<![CDATA[The Leuwikeris Dam is a dam built in two districts, namely Ciamis Regency and Tasikmalaya Regency. One of the structures of the dam is a stilling pond. Stilling ponds are built to reduce the energy contained in the flow by utilizing hydraulic jumps from a high-speed flow. The type of stilling pond at the Leuwikeris Dam is type USBR II which has a Froude number value of more than 4.5 and a discharge of more than 60m³/second. The research carried out this time calculated the amount of energy loss in the stilling pond of the Leuwikeris Dam with the USBR II stilling pond type. In finding the value of energy loss, the discharge of the Leuwikeris Dam is needed using modeling. Discharge modeling uses the NRECA method by calibrating with existing discharge, namely the discharge in Cirahong. Discharge modeling is also used with normal distribution method calculations, log normal, gumbel and log pearson type III. The results of these calculations are an NSE value of 0.756 in modeling discharge using the NRECA method and calibrated with the Cirahong discharge for 5 years and the amount of energy lost in the stilling pond of 4.78 meters.]]>

<![CDATA[Clean water plays a very important role in everyday life. However, the dry season causes a water crisis in several areas of Garut Regency, one of which is Cibunar Village, Cibatu District. The aim of this research is to plan drinking water discharge needs, storage tank capacity and water distribution planning by maximizing the potential of drilled well water as a source of raw water. There is a need for distribution engineering with PVC pipe networks and combined drainage systems. In planning this network, population projections use the geometric method for the 2023-2042 plan year with a population at the end of the plan year of 11,191 people, the total water requirement per person is 60 liters/person/day. The total domestic water requirement for one village is 671,460 liters/person/day or 7.77 liters/second at the end of the 2042 projected plan year. The complete data was then analyzed using the EPANET 2.2 application, the results of the analysis obtained the average pressure 25.23 m, average head loss 0.56 km/m and average flow speed 0.18 m/s and from the results of this analysis the ideal diameter of the distribution pipe is 100-200 mm. Meanwhile, the results of running with the peak hour scenario obtained a flow of 879 liters/hour. In planning the pump specifications required a total head of 159.34 m and a power of 45.41 Kw with pump type CR 120-5-1. Cibunar Village distribution network planning at the end of the planning year can meet community needs during the planning period.]]>

<![CDATA[Parking areas are one of the transportation infrastructures that must be well organized and managed in order to meet the need for adequate and appropriate parking spaces. The problem that occurs at Kerkof Culinary Tourism on weekends is that the parking requirements for two-wheeled vehicles exceed capacity, resulting in four-wheeled vehicles being parked on the road and causing traffic jams. This research aims to evaluate the capacity of motorized vehicle parking in the Kerkof Culinary Tourism area. The method used was a direct survey of the number and duration of parked vehicles at the research location as well as an analysis of parking needs. The analysis results show that the parking capacity for two-wheeled vehicles covering an area of ”‹”‹486 m2 for current conditions is 324 SRP with a parking index of more than 100%. This indicates that the parking area in the Kerkof Culinary Tourism area is no longer able to accommodate the demand for parking for two-wheeled vehicles. So an evaluation was carried out with the results of the need for two-wheeled vehicle parking area of ”‹”‹958.5 m2 with 639 SRP.]]>

<![CDATA[Indonesia is intensively developing various infrastructure such as buildings, mosques, roads, bridges, dams and much more. Detailed planning is needed so that construction runs smoothly and results are maximum, including planning the budget (RAB). One method that can help identify significant costs in construction projects is the Cost Significant Model Method. The Cost Significant Model method is a cost analysis method that can be used to identify significant costs in construction projects. This method uses multiple linear regression analysis. In Indonesia, building district roads is a priority to improve connectivity and community welfare. Applying the Cost Significant Model in the Garut district road project is very important for efficient cost management. The aim of this research is to identify significant cost factors in district road projects and analyze the effect of implementing the Cost Significant Model on project cost management in the region. The research results show that the cost significant model provides accurate cost predictions with a coefficient of determination of 0.943, indicating a significant influence of variables on project costs. The variables Asphalt pavement division (X4) and structure division (X5) have a significant influence on project costs, so they can be prioritized to manage risks and reduce the impact of unexpected costs. The conceptual cost estimation model from this research is Y = -339907740.45 + 380172.81 (X4) + 117874.24 (X5). Testing the validity of this model shows that the cost estimation using this model is more accurate than using the average price per square meter times the building area. The Cost Significant Model method is an effective tool for managing road project costs in Garut Regency. This can help project managers predict costs more accurately and identify factors causing cost increases.]]>

<![CDATA[Tannery sludge waste is solid waste produced by the leather tanning industry. This waste is B3 waste because it can cause itching on the skin, health problems and give off an unpleasant odor. However, this waste also contains the same compounds as cement, namely iron and aluminum, so it can be used as a substitute material for clay soil with the aim of increasing the soil's bearing capacity. Clay soil is considered poor soil if it is to be used as the basis for construction. Therefore, research was carried out on the physical properties of clay soil mixed with tannery mud waste. The method used is experimental, where the physical properties of clay soil are tested, consisting of water content, bulk density, specific gravity, sieve analysis, and Atterberg limit, plus a mixture of tannery mud waste in proportions of 0%, 25%, 50%, and 75%. % of soil weight. The results of the research showed that clay soil with the addition of tannery sludge waste resulted in a decrease in water content; increase in unit weight and specific gravity; the proportion of fine grains decreases and coarse grains increase; as well as an increase in the plasticity index.]]>

<![CDATA[Pasir Bajing TPA is the only TPA with a Sanitary Landfill system in Garut Regency. The increasing burden of landfills along with population growth makes the feasibility of the Pasir Bajing landfill interesting to study. This research aims to analyze the technical feasibility of the Pasir Bajing TPA and evaluate the feasibility of waste storage buildings in the Sanitary Landfill system at the Pasir Bajing TPA. The research method used is descriptive evaluative. Data obtained directly through field surveys. The technical feasibility of the landfill was analyzed based on SNI-03-3241-1994, while the feasibility of the waste storage building was analyzed using SNI 03-6154-1999. The research results show that the Pasir Bajing TPA technically does not fully meet the requirements according to SNI-03-3241-1994 because there are no monitoring wells, leachate collection buildings, drainage is not yet effective and a new weigh bridge has been built. The evaluation results of the waste storage building show that in terms of dimensions it meets the criteria of SNI 03-6154-1999. Based on the calculation of the capacity of the waste holding building, it is able to accommodate waste for the next 2 years, however, in terms of strength, it is not suitable because the height of the embankment and the height of the embankment or gabions do not match the strength to hold the embankment in the event of a shock or landslide.]]>

<![CDATA[Balok beton bertulang sebagai elemen struktur yang berfungsi menahan lentur dan geser dimana parameter utama untuk menentukan kuat lentur dan geser balok beton bertulang meliputi: dimensi penampang, mutu beton, mutu baja tulangan, ukuran baja tulangan dan jumlah baja tulangan yang digunakan. Dalam konstruksi parameter tersebut umumnya memiliki batasan minimum, seperti halnya dengan jarak tulangan dan dimensi penampang kecil. Untuk mendapatkan elemen struktur dengan penampang kecil namun memiliki kekuatan yang besar, dengan jarak tulangan yang kecil karena luas tulangan yang dibutuhkan besar, maka perlu dilakukan penempatan tulangan dengan cara bundel. Tujuan penelitian ini untuk mengetahui nilai kuat lentur dan geser balok beton tulangan bundel TP 4Φ6 dan balok beton tulangan tunggal Φ12 yang memiliki proporsi luas penampang tulangan yang sama. Analisis dilakukan dengan metode analisis teoritis dengan data yang diperoleh dari hasil eksperimen terdahulu. Berdasarkan hasil analisis diperoleh nilai kuat lentur rata-rata balok tulangan bundel TP 4Φ6 = 8,53 kN.m, dan balok tulangan tunggal Φ12 = 11,31 kN.m. Nilai kuat geser rata-rata balok tulangan bundel TP 4Φ6 = 58,88 kN, dan balok tulangan tunggal Φ12 = 57,92 kN. Dari hasil eksperimen dan analisis diperoleh perbedaan kuat lentur balok tulangan bundel TP 4Φ6 sebesar (6,36%) dan balok tulangan tunggal Φ12 sebesar (48,62%). Sedangkan kuat geser balok tulangan bundel TP 4Φ6 diperoleh hasil yang sama yaitu 58,88 kN dan balok tulangan tunggal Φ12 diperoleh perbedaan sebesar (0,03%).]]>

<![CDATA[Landslides are a disaster that often occurs in Ciherang Village. The high intensity of rainfall causes unstable slopes resulting in landslides in the Bandung-Garut highway area, Ciherang Village, Nagreg District, Bandung Regency. This area is a mountainous area which has medium to high potential for ground movement to occur. The aim of this research is to determine the stability of slopes using retaining wall reinforcement. Building a retaining wall in the Ciherang village area. One of its functions is to stabilize the land area around the road shoulder so that landslides or land subsidence do not occur due to natural factors (rain or flood) or the pressure factors of the loads acting on it. The method used is a quantitative descriptive method. Descriptive approach with observational data collection techniques in the field for measuring, observing and taking soil samples. A retaining wall is a structure built to support the surface of a slope. Permanent walls are used to withstand lateral pressure from unstable soil due to soil erosion or topographic conditions to overcome soil erosion problems and reduce the risk of road damage. Calculation of soil stress using the Rankine method and stability against failure of soil bearing capacity based on the Terzaghi equation based on characteristic parameters (c and Ø). The results of the calculation of the cantilever type retaining wall using soil data from laboratory tests with a retaining wall height of 8 m, base width (L) of 4.80 m, obtained a safety factor against overturning force of 3.2 and a safety factor for shear force of 1.73 . Both safety factors meet the minimum requirement of 1.20.]]>
