PARADIGMA HIDUP BERSAMA RISIKO BANJIR (RUMAH PANGGUNG MALAKA)
type: item
description: This paper examines the coping culture of the community in Malaka Regency, East Nusa Tenggara Province (NTT), in responding to annual floods through the practice of stilt house construction. Although proven to be resilient against floods, stilt houses have not yet become the primary choice in housing policies and public infrastructure development. This approach is not intended as a single solution for flood risk reduction, but rather as part of a living with disaster approach, as recommended by the United Nations. This study highlights that floods are a complex phenomenon caused by natural and anthropogenic factors, and exacerbated by climate change. Based on literature review and field observations, it was found that local stilt houses made of wood and gewang leaves have eco-architectural advantages that support environmental adaptation. Although the community has started adopting modified stilt house models, government agencies still construct conventional buildings that are less adaptive to flood risks. Therefore, supportive policies are needed to preserve and develop this coping culture as part of a sustainable disaster risk management strategy.

ANALISIS NERACA AIR PADA DAS MANIKIN KABUPATEN KUPANG PROVINSI NUSA TENGGARA TIMUR
type: item
description: This study aims to analyze the annual water balance and develop a water allocation plan for the Manikin Watershed (DAS Manikin) located in Kupang Regency, East Nusa Tenggara Province (NTT), Indonesia. The primary motivation for this research is the imbalance between water availability and demand, particularly during the dry season. The methodology includes the collection of climate and infrastructure data, analysis of water demand and availability, and water balance modeling using Excel and Cropwat 8 software. Reliable discharge was calculated using the FJ Mock method with an 80% probability (Q80%). The analysis revealed that the peak irrigation water demand occurs in August, reaching 0.54 l/s/ha, while the available discharge in the same month is only 0.67 m³/s, indicating a significant water deficit. This study offers technical and policy recommendations for efficient, equitable, and sustainable water management in semi-arid regions vulnerable to drought.

PERILAKU PEMADATAN TANAH EKSPANSIF DI BAWAH STANDAR MAXIMUM DRY DENSITY (MDD)
type: item
description: Abstrak: Tanah ekspansif memiliki perubahan volume signifikan akibat fluktuasi kadar air yang dapat mengancam stabilitas konstruksi. Pemadatan tanah berfungsi untuk menurunkan porositas dan meningkatkan berat isi kering, sehingga memperbaiki sifat mekanik tanah. Penelitian ini mengevaluasi pengaruh pemadatan di bawah Maximum Dry Density (MDD) pada tingkat 95%, 90%, dan 85% terhadap karakteristik fisik dan mekanik tanah ekspansif di wilayah Kupang. Metode meliputi pengujian kadar air, berat isi kering, California Bearing Ratio (CBR), dan uji kuat geser langsung. Hasil menunjukkan penurunan pemadatan menyebabkan peningkatan kadar air dan porositas, serta penurunan berat isi kering dan nilai CBR. Meskipun kohesi meningkat, sudut geser dalam menurun signifikan, mengindikasikan penurunan kestabilan tanah. Studi ini menegaskan pentingnya pencapaian MDD untuk menjamin keandalan struktur pada tanah ekspansif.

SDOF STRUCTURE RESPONSE DUE TO SINUSOIDAL LOADS USING NUMERICAL METHODS
type: item
description: Dynamic loads are types of loads that change in magnitude and/or direction with time. Structures that frequently experience dynamic loading can receive repeated (periodic) loads. This repetitive load pattern can be in the form of a graph of a sine function or cosine function, therefore the structure needs to be evaluated against dynamic loads with a sinusoidal pattern. The aim of this research is to determine the maximum response of a structure that can be modeled as a single degree of freedom system due to sinusoidal loads. The method used in this research is a numerical method. Based on the results and analysis of the response of the SDOF structure in this research, both Linear Acceleration and Average Acceleration methods show the same results. From the results and analysis it can be concluded that the greater the mass, the greater the maximum displacement produced or in other words the mass is directly proportional to the maximum displacement. This is different from stiffness, the greater the stiffness, the smaller the maximum displacement produced, or in other words, stiffness is inversely proportional to maximum displacement. Variations in mass and stiffness produce maximum velocities whose values are all negative. This shows that the maximum speed occurs in the direction opposite to the direction of the load. The speed and acceleration values for each additional mass tend to increase, while the speed values for each additional stiffness tend to decrease.

ANALISA STABILITAS LERENG MENGGUNAKAN PERKUATAN SOIL NAILING PADA SISI KANAN PELIMPAH BENDUNGAN ROTIKLOT KABUPATEN BELU PROVINSI NUSA TENGGARA TIMUR
type: item
description: This study aims to analyze the slope stability of the right side spillway of Rotiklot Dam in Belu Regency, East Nusa Tenggara, which is dominated by high-plasticity Bobonaro clay with low shear strength. Evaluations were carried out for the existing conditions and after reinforcement using the soil nailing method and its combination with gabions. The analysis utilized Rocscience Slide software and manual calculations. Results indicate that soil nailing increased the slope safety factor from 0.998 to 2.065 under normal conditions, and from 0.708 to 1.436 under seismic conditions. The combination of soil nailing and gabions yielded better results. These findings indicate the effectiveness of slope reinforcement methods as a geotechnical solution in landslide-prone areas.

PENGARUH ON STREET PARKING TERHADAP KINERJA RUAS JALAN MOCH. HATTA KOTA KUPANG (Studi Kasus Di Depan RSUD Prof. Dr. W.Z. Johannes)
type: item
description: On-street parking can affect the performance of the road section due to the reduction in the effective width of the road. This problem occurs on Jl. Moch. Hatta in front of Dr. Prof. W.Z. Johannes Hospital. The purpose of this study was to determine the characteristics of parking on the roadside and its impact on the performance of the road section. The research method uses parking characteristic calculations such as volume, accumulation, duration, index and turnover, while the calculation of road section performance uses the PKJI 2023 method. The results of the study related to the characteristics of on-street parking obtained a parking volume on the left side of the roadside of 261 vehicles and on the right side of 248 vehicles. The highest parking index per hour on the left side of the road for motorcycles was 63% and for cars 96%, while on the right side of the road for motorcycles it was 25% and for cars 90%. These results show that the parking index is dominated by passenger car. The results of the road section performance obtained the highest traffic volume is 1,112 pcu/hour, the capacity in existing conditions is 1,776 pcu/hour with a DJ value of 0.63 (LOS C). The average speed obtained is 16.06 km/hour and the free flow speed obtained is 42.854 km/hour. The level of road service from the relationship between speed and DJ is obtained as LOS E. The effect of on-street parking on the performance of the road section is 42% to 68%. This is calculated based on two simulation condition, first condition if there only 1 sided on-street parking and the second condition if on-street parking is eliminated.

EVALUASI PEMENUHAN STANDAR TEKNIS FASILITAS PEJALAN KAKI PADA KAWASAN KUANINO KUPANG
type: item
description: The Kuanino area in Kupang City is an area that is dense with goods and services trading activities. The ease of access to this area is supported by various existing transportation infrastructure facilities. One thing of concern is access to pedestrian infrastructure, which often gets the last priority in the development of road transport infrastructure. Pedestrian facilities can be said to be good if they meet technical planning standards that accommodate all levels of society, including people with disabilities. The purpose of this study was to evaluate the fulfillment of existing pedestrian facilities to the minimum technical service standards based on applicable regulations and guidelines. The research method uses an evaluation of the existing condition of pedestrian facilities against the standard criteria for pedestrian facilities. 03/PRT/M/2014. The results of the study show that the safety aspects (height differences and guiding tiles for people with disabilities), accessibility (disruption to the sidewalk), connectivity (crossing facilities) and support still do not meet the technical standard criteria, so it is necessary to improve pedestrian facilities on Jl. Gen. Sudirman (Kuanino) based on the 3E model, namely engineering, education and enforcement.

PENYELIDIKAN TANAH MENGGUNAKAN METODE UJI SONDIR
type: item
description: Cone Penetration Test (CPT) or sondir is a method designed to determine and test the strength of the soil layer. This sondir test has been carried out in Tunfeu Village, Nekamese District, Kupang Regency, East Nusa Tenggara to determine the resulting bearing capacity and determine the type of foundation that is suitable for the research location point. The soil investigation method is carried out by direct testing in the field using a sondir tool. Secondary data were obtained from several literature studies. Primary data obtained from sondir results at three predetermined location points. Data analysis used two parameters at each depth, namely the Conus Resistance Value (qc) in kg/cm2, and the total shear value (Tf) in kg/cm units. The two parameters above were recorded for every 20 cm interval where at point 1 the value of qc ³ 245 kg/cm2 is obtained at a depth of –11.60 m with a Tf 337.33 kg/cm. At point 2 the value of qc ³ 225 kg/cm2 is obtained at a depth of –21.20 m with a Tf 394 kg/cm. While at point 3 the value of qc ³ 235 kg/cm2 is obtained at a depth of –19.60 m with a Tf 548.67 kg/cm. Based on the results of the sondir above, the type of foundation that is suitable for the soil conditions in Tunfeu Village is a pile or deep foundation (bored pile).

PENGARUH PARKIR DI BADAN JALAN TERHADAP KINERJA RUAS JALAN CAK DOKO
type: item
description: Management of on-street and off-street parking is important in controlling traffic so that congestion, pollution, noise can be reduced, and in turn it can improve environmental quality standards, the quality of pedestrians and cyclists movement (Hobbs, 1995) . One of the cases that hinders traffic flow and reduces the level of road service on Jalan Cak Doko is the presence of many public facilities such as offices, restaurants and shops in the area. This study aims to examine road performance on the Cak Doko street section. Analysis using the Indonesian Road Capacity Manual method shows that the performance of the road segment is poor, with a degree of saturation for the existing condition of 0.77 and for the no-parking condition of 0.72. The LoS value for existing conditions reaches 0.77 (Category E) where the traffic volume approaches or is at an unstable flow capacity and sometimes stops. And LoS for no parking conditions is 0.72 (Category D) where the flow is approaching unstable, the speed is still controlled and the Q/C level is still acceptable. The dominant cases that contribute to traffic congestion and reduce the level of road service are on-street parking activities. In order to improve road performance, one aspect of improvement is the management of on-street parking activities.

STRATEGI PENGELOLAAN JALAN KOLEKTOR BERDASARKAN KONDISI FUNGSIONAL JALAN
type: item
description: Road damage in general is a condition of road buildings that do not function both from a technical point of view, benefits, and safety. Road damage is one of the factors causing traffic jams and accidents. This study aims to determine the pattern of road handling based on the functional condition of the road on the Kupang urban collector road. The identification of the damage conditions is carried out using the SDI formula wherein the damage conditions are determined by the level of road damage on each of the observed roads. Furthermore, based on the level of road damage, a road handling strategy is determined. In this case, because the quality of accessibility and mobility services between regions is affected by not only physical connectivity but also functional aspects, to facilitate the process of identifying the service performance of the collector road network, a road functional condition mapping model is used. The results of the mapping clearly show which segments and/or parts of the road are damaged and have an impact on the smoothness and safety of inter-regional travel. That's why QGIS is used for the mapping. The results showed that in the Maulafa sub-district, out of a total of 17 sections in the region, there were 6 roads that had to be repaired. The implication of the results of this study is that the results of the mapping of the functional condition of the road not only allow openness and at the same time ease of access, but also facilitate the preparation of programs for handling road damage and the provision of a budget for its management. Therefore, in the future this model needs to be developed through the use of WebGIS-based applications and by involving community participation in the aspect of supplying road condition data.

MENGENAL BERBAGAI MODEL HIDROLOGI DI INDONESIA
type: item
description: The hydrological model is a simplification of the complexity of a real-world hydrological system of a watershed. Since 1890, various hydrological models have been developed to assist decision makers in formulating watershed management scenarios. This study examines nine hydrological models through a literature review. The nine models are HydroOffice BFI+, HEC-HMS, HEC-SSP, EPA-WMOST, EPA-AGWA, EPA-SWMM, AGNPS, ANSWERS, and ANFIS. The results of the study are briefly explained as follows. Flood analysis could apply one of the tools namely HEC-HMS, AGWA, SWMM, AGNPS, ANSWERS, and ANFIS. However, certain flood analysis programs need to be combined with GIS and HEC-SSP to get an adequate analysis. Baseflow separation analysis could use BFI+ with the daily rainfall as input data. Analysis of the rate of erosion and sedimentation could apply AGWA, AGNPS, ANSWERS. The HEC-SSP model provides assistance in correcting incomplete and inconsistent data. In terms of water resource management on a watershed scale, the WMOST and AGNPS models can be used. However, some types of models have limitations. Therefore, in applying the model, it is necessary to combine several models to get optimal results. In addition, the results of the hydrological model analysis need to be confirmed by field measurements

ANALISA MATRIKS KEKAKUAN PADA BALOK NON PRISMATIS DENGAN MENGGUNAKAN PRINSIP ELEMEN HINGGA
type: item
description: In structural planning, planners often choose a uniform landscape across a stretch of structure. But sometimes for certain certain contour selection of non-prismatic views, it is necessary to analyze the rigour matrix on the non-prismatic beam to make it easier and faster for calculations in structural analysis. The prismatic beam viewer selected in this study is a simple beam at one long landscape but has a distinct geometric form and type of material. The results of this study are the results of the rigour structure for a non-prismatic beam affected by the value of modulus elasticity that describes the type of material, as well as the broad and long landscape that describes the geometry of a non-prismatic beam viewer.

PENGARUH VARIASI JUMLAH TUMBUKAN TERHADAP NILAI MARSHALL HASIL PEMADATAN PADA ASPAL HRS-WC SECARA MANUAL DAN ELEKTRIK
type: item
description: In this study, an analysis was conducted on the influence of the number of compaction impacts on the density of asphalt mixtures using the Marshall method on Hot Rolled Sheet Wearing Course (HRS-WC) Thin Asphalt Concrete (Lataston) mixture. The main objective of this research is to compare the compaction results between manual and electric methods. To achieve this, variations in the number of impacts were performed, namely 2 x 25, 2 x 40, 2 x 50, 2 x 60, and 2 x 75 impacts. The research results showed a significant difference between the manual and electric compaction methods in the observed Marshall parameters. Especially with 2 x 75 impacts, a noticeable difference was observed with a stability difference percentage of up to 2.505%. Therefore, it can be concluded that although the manual and electric compaction methods yield relatively similar results in terms of Void In Mix (VIM), Void In Material Aggregate (VMA), and Void Filled With Bitumen (VFB), there is a significant difference in stability, flow, and Marshall Quotient (MQ) parameters. This research has important implications in asphalt compaction practice and can be used as a guideline for selecting the most suitable compaction method to produce optimal quality asphalt mixtures.

OPTIMALISASI DESAIN PONDASI MESIN TIPE BLOK PADA PENYELIDIKAN TANAH DI INDRAMAYU
type: item
description: Along with the development of micro-hydro power plants, machines with very heavy weights are needed, therefore a special foundation is needed that can support the weight of the machine in an active or inactive state. Machine foundations are different from foundations in general, machine foundations require dynamic analysis, namely when the machine is operating, in this study four foundation calculations are taken into account, namely foundations P1, P2, P3 and P4, foundation P1 has dimensions of 10 m long, 3.5 m wide and 2.2 m high, P2 foundation is by widening 2 m, so that the width changes to 5.5 m, as well as for the P3 foundation, namely by extending 2m, so that the dimensions are 12 m long, and for the P4 foundation, by extending and widening 2m, so that the dimensions are 12 m long and 5.5 m wide. The results of the calculation of the static load, the foundations P1 to P4 meet the requirements because the load received by the foundation is 394.66 kN or 39,466 tons, while the carrying capacity exceeds the load, namely 138.13 tons, 217.06 tons, 165.75 tons and 260.7 tons, based on the comparison between the weight of the machine and foundation weight > 3 means that it meets the requirements for the magnitude of the ratio, 4.68, 7.36, 5.62 and 8.83. In addition to static loads, in the planning of machine foundations that need to be checked, namely dynamic loads, namely the value of the ratio of frequency and natural frequencies, the value cannot be less than 1, foundations P1 to P4 have a value of more than 1, which is equal to 1.16, 1.31, 1.22 , and 1.37 for the horizontal direction and 1.14, 1.28, 1.16 and 1.31 for the vertical direction, for the magnification factor value the value must be below 1.5, all foundation models meet the requirements, namely the values ??are 1.44, 1.25, 1.36 and 1.18 for the horizontal direction and 0.88, 0.76, 0.82, and 0.72 for the vertical direction. And what is very important in foundation planning is determining the comfort of w…

HUBUNGAN KELAS SITUS TERHADAP BESARAN GAYA GESER SESISMIK SESUAI SNI 1726:2019
type: item
description: Earthquakes are natural phenomena that can cause building collapse and loss of life. During an earthquake, buildings standing on the ground will experience movement at its base, the acceleration arising from ground motion will cause horizontal / lateral inertial forces on the mass of the structure, then used as a plan earthquake force that must be reviewed in planning. According to article 7.8 of SNI 1726:2019, the seismic base shear force is the product of the seismic response coefficient (Cs) and the building's seismic weight (W). The seismic response coefficient must be determined by the spectral acceleration parameter (SDS) which is highly dependent on the site class classification regulated in Article 5 of SNI 1726:2019, which uses the top 30 m layer profile data from the soil investigation. This study uses a 1-span reinforced concrete frame with 3 floors and 20 locations spread across Kupang City to see the effect of site class on the magnitude of seismic base shear force. The results showed that the base shear force of SC site increased by 87.5% against SB site, the base shear force of SD site increased by 9.22% against SC then the shear force of SE site decreased by 1.94%..

type: item
description: The hot mix asphalt-aggregate mixture in the construction of asphalt concrete roads generally consists of three layers: the base layer, intermediate layer, and surface layer placed on a granular subbase. One of the asphalt concrete layers is the Intermediate Layer, which is a hot asphalt mixture consisting of aggregate, asphalt material, and filler mixed at a central mixing plant. The resulting mixture is spread and compacted on the Aggregate Base Layer. The hot asphalt mixture is designed according to the General Specifications for Road and Bridge Construction by the Directorate General of Highways in 2018 (Revision 3) to ensure that the design assumptions regarding Asphalt Content, Air Voids, Stability, Flexibility, and Durability are in line with the planned traffic. Research results indicate differences in Marshall characteristics from Marshall test results for the Intermediate Layer asphalt concrete mixture (AC-BC) of the two compositions. Almost all Marshall properties meet the Directorate General of Highways specifications in 2018 Revision 3, except for Flow with a particle size of 19 mm, which does not meet the specified flow range of 2 – 4 mm, and Marshall Stability for Aggregate Residue with a particle size of 19 mm, which does not meet the specified minimum of 90%. Meanwhile, the Optimum Asphalt Content (OAC) values for Aggregate with a particle size of 25 mm are 5.11%, and for Aggregate with a particle size of 19 mm, it is 5.18%.

type: item
description: Development of socio-economic activities occurs linearly with respect to the road network. Along the edge of the Timor Raya Timor Raya road Km 8+800 to Km 9+000 the side barriers are now getting higher, both due to vehicle parking on the road body, as well as due to vehicles entering and leaving the parcel (access) and pedestrians on the shoulder of the road and road crossings. Traffic problems that arise due to the activity of vehicles parked on the road are of course detrimental to road users such as when the vehicle is parked or when the vehicle exits the parking lot, therefore parking controls on the Timor Raya road Km 8+800 to Km 9+000 is the most important thing to do to control traffic so that congestion, pollution, noise can be minimized. Based on the analysis conducted using the Indonesian Highway Capacity Manual (MKJI, 1997). It is known that the peak volume occurred on Monday, 08 May 2023 at 17.30-18.30 WITA with a volume of 2162.75 PCU/hour, a capacity of 2366.63 PCU/hour, and the performance of Jalan Timor Raya, Oesapa Km 8+800 to Km 9+ 000, is at service level E with a DS value of 0.91. with a light vehicle free flow speed of 35.8 km/hour and an average speed of 22 km/hour. in conditions without light vehicle (LV) and heavy vehicle (HV) parking on the road, enter service level D where the DS value reaches 0.78, with a capacity of 2781.83 pcu/hour, free flow speed of light vehicles 38.9 km/hour and an average speed of 28 km/hour.

type: item
description: Water is a basic need for human life, where its availability and optimal distribution play an important role in improving people's welfare. One of the water sources that is commonly used is groundwater. Based on data from the Central Statistics Agency of East Nusa Tenggara in 2018, there are 2,576 groundwater springs in the province, with 666 of them in South Central Timor Regency. However, challenges in the clean water distribution system, such as limited access and difficult geographical conditions, often hinder the fulfillment of water needs for the community. This study aims to analyze the hydraulic conditions of the clean water transmission network at SPAM Bonleu, Tobu District, South Central Timor Regency. The research methods include literature studies, data collection through field studies, data processing using AutoCAD Civil 3D, EPACAD, and EPANET V2.0 software, as well as hydraulic analysis of pressure, flow velocity, and head loss in the transmission network. The modeling results show that the pressure in the network is greater than the required standard, which is more than 250 m of water column. The flow velocity meets the minimum standard of 0.3 m/s, while the head loss is within the permitted limit, which is not less than 10 m/km. However, there is one parameter that does not meet the requirements, so further evaluation is needed for system optimization

ANALISIS PENAMBAHAN KELOMPOK KERJA DAN JAM KERJA (LEMBUR) TERHADAP WAKTU PENYELESAIAN ITEM PEKERJAAN DAN BIAYA ITEM PEKERJAAN
type: item
description: Overcoming the problem of time delays requires handling using proven methods or alternatives such as adding work groups or adding working hours. Adding working hours and labor is usually used as a solution to speed up the completion time of a project because by adding working hours, the time that can be used to work increases so that the resulting production increases and the completion time. Adding working groups and working hours to the selected work items from the critical path, namely Class A Aggregate Foundation Layer, Wearing Layer Laston and Fc 15 mpa Concrete Structure produces a new minimum production so that the completion time of the three work items is reduced, but also increases the costs required to complete the work items. Adding Working Hours (Overtime) to the three work items on the critical path, the first hour of completion duration is reduced by 12.5% in the completion duration of the work item, the 2nd hour by 22.22% in the work item, the 3rd hour by 30% in the work item. While the cost of Class A Aggregate Foundation Layer, the 1st working hour cost is 0.15%, the 2nd hour is 0.31%, the 3rd hour is 0.31%. In the Wear Layer Laston work item, the cost is 0.08% in the 2nd hour, 0.16% in the 3rd hour and 0.16%. In the fc 15 Mpa Concrete structure work item, the 1st working hour is 2.01%, the 2nd hour is 4.01% and the 3rd hour is 4.01%. The addition of labor groups for the Class A Aggregate Foundation Layer work item, the duration is reduced by 32%, the Wear Layer Laston work item is 13%, and in the Fc 15 Mpa Concrete Structure work item is 50%. The cost of the Class A Aggregate Foundation Layer work item increased by 0.37%, the Wearing Layer Laston work item increased by 8.03% and the fc 15 Mpa Concrete Structure work item did not experience an increase.

ANALISA WAKTU PENYELESAIAN PADA PROYEK PENINGKATAN JALAN KONSTRUKSI HRS BASE KELURAHAN BATUPLAT KOTA KUPANG DENGAN METODE EARNED VALUE
type: item
description: A construction project is a series of activities to achieve a goal within certain time, cost and quality limits. Construction projects require resources, namely humans, materials, equipment, implementation methods, money, information and time (Kerzner 2009). Project resources are planned to achieve project goals within time, cost and quality constraints. The challenge in project implementation is how to plan an effective time schedule and efficient cost planning without reducing quality. In the road improvement project in Batuplat sub-district, the Earned Value method has not been applied as this method functions as a tool for evaluating project performance and the results of this evaluation can be used to estimate whether the project can be completed on time or not. From the results of initial observations, the author knows that in the project implementation process, weekly evaluations were not carried out, this could result in the contractor not knowing what obstacles could prevent the project from being completed on time. The author considers that the absence of this method cannot provide an estimate that this project can be completed on time because there are two possibilities that this project can be completed on time or not.

PERENCANAAN RAINWATER HARVESTING SYSTEM SMA NEGERI 1 TAEBENU, NUSA TENGGARA TIMUR
type: item
description: Rainwater Harvesting System (RWHS) is a simple concept for utilizing water resources, by collecting rainwater that falls in the roof and channeling it into a reservoir. Non domestic water needs in school buildings are needed in large quantities considering the large number of water users. With the RWHS concept, it is hoped that it can provide an alternative solution for using rainwater at SMA Negeri 1 Taebenu. Basen on the results of the water balance analysis at SMA Negeri 1 Taebenu, the water deficit was greatest in Juli at 0,61 liters/s. Based on these values, 2 rainwater storage tanks are planned with a capacity of 4,5 m3 each with dimensions of 1,5 x 1,5 x 2 meters. The storage tank is designed to be below groung level due to limited land. Rainwater is only used for bathroom purposes and watering plants, so the design of the reservoir is made simple, just using a dirt filter in the gutter to dispel dirt carried from the roof into the tank.

type: item
description: Heavy traffic results in vehicles piling up on the shoulder of the road due to the lack of adequate parking space. So it will cause traffic to be disrupted because it only optimizes one lane. Therefore, the Evergreen Clinic building has a big influence on changes in road use, because the Evergreen Clinic does not have a large parking area. This research aims to determine and anticipate the impact of denser traffic around the Evergreen Clinic area. This research examines the traffic impact analysis in terms of traffic loading that occurs due to the existence of the Evergreen Medika Health Facility in Sorong Regency. Where the impact of parking on traffic performance on the roads around the Evergreen Clinic is on average in category C, this can also explain that there is a negative impact, namely congestion due to parking activities on traffic. The effect of parking on traffic performance on the road around the Evergreen Clinic on Sundays and Mondays has a correlation coefficient of 1.00, meaning there is a very strong relationship which indicates that parking activity on Mondays and Sundays has a very strong influence on the traffic volume on the road.
