Islamic Boarding School has a treatment capacity of 33 m3 and an area of 24 m2. Based on the results of initial wastewater quality tests on communal WWTP, the TSS, COD, and BOD parameters are above the quality standard threshold based on the Wastewater Quality Standard of the Minister of Environment Regulation Number 68 of 2016. This evaluation aims to determine the processing efficiency of communal WWTP and evaluate the processing unit in communal WWTP as well as alternative improvements that effectively reduce the parameters of pH, TSS, BOD, COD, and fatty oils. This research method is descriptive analytics, which analyses problems from data collected descriptively to find solutions to problems. The results of this evaluation show that the TSS, COD, and BOD parameters are above the quality standard threshold. The pH parameter increased by 3.6%, removal efficiency for BOD by 76.4%, COD by 71.9%, TSS by 84.3%, and oil grease by 91.9%. Alternative WWTP improvements are carried out by redesigning the Communal WWTP, which consists of calculating the equalization unit, precipitator I, anaerobic filter, Precipitator II, disinfection, and sludge thickener, Sludge digester, sludge drying bed and analysis of the Budget Plan Cost (RAB). The communal WWTP redesign requires a land area of 52.62 m2 with a processing capacity of 56.8 m3 and a cost budget plan of Rp.157,224,000.00. The redesign results of this evaluation can reduce environmental impacts due to domestic wastewater.

Pontianak City has a low ground elevation and a reasonably high groundwater level. The distribution of clean water from regional companies tends to be less than optimal, and there is high rainwater runoff, causing the channel discharge to increase along with the growth of land converted into residential and business areas. Therefore, houses often use fresh water storage, both raw and rainwater, to meet clean water needs. One type that is often used is concrete culverts. However, concrete culverts have gaps in the joints that have the potential to contaminate storage water. The development of modular wells can be an option that is superior in various aspects to concrete culverts. The results showed that installing polypropylene modular wells costs less than concrete culvert wells. In addition, the use of modular wells also has advantages in terms of ease of installation and maintenance, as well as efficiency in land use. Endurance strength Modular wells can carry a load of up to 24 tons/m2. Thus, the results of this study are expected to provide alternative methods of storing clean water in Pontianak City that are more effective and efficient in terms of cost and quality by considering technical and environmental factors.

The height of the bridge arch significantly impacts the strength and structural efficiency. Research on the height of the Tayan Bridge arch was conducted to determine the values and behaviour of member forces, structural weight, and deflection and to design the optimal arch height geometry. This research involved five variations of the arch height. The bridge structure was modelled using AutoCAD software. Relevant bridge loading data based on the SNI 1725-2016 standard was inputted into AutoCAD for structural design, and then the structure was modelled and analysed using SAP2000. The analysis results provided information on the bridge weight, deflection, and member forces. The analysis results were then compared with the bridge arch height, and this comparison was presented in the form of graphs. From the analysis results, it can be concluded that the bridge arch height has a positive linear relationship with the bridge weight. Tensile and compressive forces exhibit opposite behaviour. Increasing the arch height with constant value results in weight, deflection, and member force variations. Constantly expanding the arch height also does not lead to an increase in the stiffness of the bridge. Structurally, the optimal arch height is 42.134 meters.

Flooding can occur because the volume of water flowing in a river exceeds its drainage capacity. The high rainfall intensity can cause the Sekayam River to overflow in Sanggau Regency. A maximum of 1 (one) day of rainfall data from observation stations is needed for flood control and management. However, some observation stations still need complete 1 (one) day maximum rainfall data. One alternative that can be used to obtain rainfall data is to utilize the TRMM satellite. However, the data generated by the TRMM satellite cannot be fully utilized due to interference with infrared and microwave radiation in the atmosphere. It is necessary to make corrections first before rainfall data is used. Correction is done using the correction equation obtained through the test results. Testing begins with quality testing of observation station rainfall data by conducting homogeneity testing using the data analysis tool with the t-test method: two samples assuming equal variances in MS. Excel and consistency testing using the Worsley Likelihood Ratio Test method. Then, the TRMM satellite rainfall data is filtered by looking at the correlation coefficient results with the condition ≥ 0.5 against the observation station data, which has homogeneous and consistent data properties. TRMM rainfall data that passes will go through the calibration and validation stages. The correction equation obtained during the calibration stage and produces the most significant correlation coefficient in the validation stage will be used to correct TRMM satellite rainfall data so that TRMM satellite rainfall data will be obtained after correction. Data after correction will be tested again with data before correction to see the data quality by looking at the results of RMSE and relative bias.The homogeneity and consistency test of observation stations states that all observation stations have homogeneous and consistent results. TRMM rainfall data that passes the data filtering stage is 21 Grids. TRMM rainfall data with a correction equation with the highest correlation coefficient results is on Grid 27 with the correction equation Y = 0.976 x - 10.685 and a correlation coefficient of 0.737. The correction equation is used to correct rainfall data on 21 Grids that have passed the data filtering stage. The results of RMSE and relative bias in TRMM rainfall data after correction using the correction equation Y = 0.976 x - 10.685 show tiny and satisfactory results in interpretation so that the correction equation can be utilized as a correction of TRMM rainfall data in the Sekayam Watershed.
洪水泛滥可能是因为河流的水量超过了其排水能力。高强度降雨会导致 Sekayam 河在 Sanggau 地区泛滥。洪水控制和管理需要观测站提供最多 1（一）天的降雨量数据。但是，一些观测站仍然需要完整的 1（一）天最大降雨量数据。获取降雨量数据的一个替代方法是利用 TRMM 卫星。然而，由于受到大气层中红外线和微波辐射的干扰，TRMM 卫星生成的数据无法得到充分利用。在使用降雨数据之前，有必要先进行修正。校正是利用通过测试结果获得的校正方程进行的。 测试首先要对观测站降雨量数据进行质量测试，使用数据分析工具进行同质性测试，采用 t 检验法：在 MS.Excel 进行一致性测试，并使用 Worsley Likelihood Ratio Test 方法进行一致性测试。然后，根据观测站数据与 TRMM 卫星降雨量数据的相关系数≥ 0.5 的结果，对 TRMM 卫星降雨量数据进行筛选，筛选出具有同质性和一致性的数据。通过的 TRMM 雨量数据将进入校准和验证阶段。校准阶段得到的、在验证阶段产生最显著相关系数的校正方程将用于校正 TRMM 卫星降雨数据，从而得到校正后的 TRMM 卫星降雨数据。校正后的数据将与校正前的数据再次进行测试，通过均方根误差和相对偏差的结果来检验数据质量。通过数据过滤阶段的 TRMM 降水数据为 21 个网格。TRMM 降雨量数据的修正方程相关系数结果最高的是第 27 网格，其修正方程为 Y = 0.976 x - 10.685，相关系数为 0.737。该修正方程用于修正 21 个已通过数据过滤阶段的网格的降雨量数据。使用修正方程 Y = 0.976 x - 10.685 对 TRMM 雨量数据进行修正后，其 RMSE 和相对偏差结果显示极小，解释结果令人满意，因此可以利用修正方程对 Sekayam 流域的 TRMM 雨量数据进行修正。

The high number of traffic accidents is a problem for the government in realizing traffic security, safety, and smoothness. Intersections are the most common point of conflict, especially unsignalized intersections. The research location of the intersection of Jl. Budi Utomo - Jl. 28 October-Jl. Parit Nenas, Siantan Hulu Village, North Pontianak District, and Pontianak City intersect environmental-type commercial roads with many vehicles and education centers. The research objectives are to identify traffic conflicts, analyze the level of traffic conflicts, and provide alternatives to overcome problems.Traffic Conflict Technique is an observation method to analyze traffic conflict that illustrates the seriousness of the conflict. The research data used CCTV recording for two days, Saturday and Tuesday. The Traffic Conflict Technique method uses the Time to Accident and Conflicting Speed values to determine the seriousness of the conflict.Based on the analysis of the Traffic Conflict Technique method, the research location with 34 vehicle conflicts has a severe level of conflict that could potentially cause accident risk. The level of serious conflict is 27 vehicle conflicts, with a percentage of 79.41%. Vehicle speed in the class 15 km / h - 19 km / h is the most severe conflict speed, with 12 vehicle conflicts and a percentage of 44.44%. Accelerating vehicle behavior is the most severe conflict, with 25 vehicle conflicts and a percentage of 83.33% of accidents that have the potential to occur. Alternatives to reduce the causes of accidents are adding traffic signaling devices and traffic signs to improve safety.

Acceleration on projects is frequently used when there is a mismatch between the actual and planned schedules. In addition, acceleration is frequently implemented in response to requests from the project owner to complete the project as quickly as possible to meet specific goals so that the building can be used immediately. The owner of the Dekranasda Building and Hall in West Kalimantan requested that the project be finished immediately so that the Dekranasda Building could be used as the location for a national UMKM exhibition event. The initial plan for this project was scheduled for 152 working days. Because there would be an exhibition event, the project was accelerated to 128 working days. The purpose of this research is to accelerate the project for 24 days. The stages of this acceleration analysis start from finding what activities can be softened, then compiling a network diagram to identify activities on the critical path, followed by crashing analysis to get crash duration, crash cost, and cost slope, then Time Cost Trade-Off analysis is carried out. This research uses the PDM (Precedence Diagram Method) method applied to Microsoft Project to compile a Network Diagram. The results of the acceleration analysis show that the crashing process is carried out until the 12th crashing to meet the target acceleration duration of 128 working days from the normal duration of 152 working days, and the usual 24-day length is shortened. Twelve tasks have been added, raising the overall project cost from Rp. 6,794,007,874 to Rp. 7,091,725,614 by a total of Rp. 297,717,741.

In addition, acceleration is frequently implemented in response to requests from the project owner to complete the project as quickly as possible to meet specific goals so that the building can be used immediately. The owner of the Dekranasda Building and Hall in West Kalimantan requested that the project be finished immediately so that the Dekranasda Building could be used as the location for a national UMKM exhibition event. The initial plan for this project was scheduled for 152 working days. Because there would be an exhibition event, the project was accelerated to 128 working days. The purpose of this research is to accelerate the project for 24 days. The stages of this acceleration analysis start from finding what activities can be softened, then compiling a network diagram to identify activities on the critical path, followed by crashing analysis to get crash duration, crash cost, and cost slope, then Time Cost Trade-Off analysis is carried out. This research uses the PDM (Precedence Diagram Method) method applied to Microsoft Project to compile a Network Diagram. The results of the acceleration analysis show that the crashing process is carried out until the 12th crashing to meet the target acceleration duration of 128 working days from the normal duration of 152 working days, and the usual 24-day length is shortened. Twelve tasks have been added, raising the overall project cost from Rp. 6,794,007,874 to Rp. 7,091,725,614 by a total of Rp. 297,717,741.","PeriodicalId":52838,"journal":{"name":"Jurnal Teknik Sipil","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139381183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each district or city is required to establish a Public Service Mall for services to the community, therefore the Government wants to make the Kapuas Indah Market building multifunctional which has been neglected for a long time by having a Public Service Mall on the 3rd floor of the Kapuas Indah Market with a total building area of ± 7,380m2. The construction of this renovation will certainly have various impacts so it is necessary to carry out a feasibility study in terms of technical and financial aspects.Analysis of the technical aspects carried out is based on the Basic Building Coefficient (KDB) of 78.79%, Building Floor Coefficient (KLB) of 2.36, Green Area Coefficient (KDH) of 21.20%, Parking Space Requirement of 581SRP, and Accessibility The locations reviewed are in accordance with applicable regulations and guidelines that the technical aspects of the renovation of the construction of the Kapuas Indah Market and Public Service Mall can be said to be feasible or have met the requirements in the construction of a project. While the results of the financial feasibility analysis show that the renovation project for the construction of the Kapuas Indah market and the Public Service Mall is feasible (profitable) because the results obtained using the Net Present Value (NPV) obtained a value of Rp. 10,223,725,624 > 1, the value of the Benefit Cost Ratio (BCR) of 1.1409 ³ 1 , the Internal Rate Of Return (IRR) is 7.78% > MARR, and the Payback Period (PP) value is 22 years 11 months 14 days < the investment plan age is 30 years. The sensitivity results show that the feasibility assessment of financial parameters is very sensitive to the IRR parameters for increasing expenses and decreasing revenue costs.

Road maintenance on the section of the road classified as a district road in the Sintang sub-district is the responsibility of the Sintang District Government. The financial constraints of the Sintang District Government, allocated annually in the Regional Revenue and Expenditure Budget (APBD) of Sintang District, pose a challenge in realizing the plan for district road maintenance, whereas funding for road maintenance needs to be budgeted regularly to maintain the road conditions in good shape, therefore, in this case, stakeholders or decision-makers are expected to be able to consider and decide which road sections should receive recommendations for "urgent," "immediate," and "postponed" maintenance. The chosen road maintenance points must not solely prioritize the lowest construction costs, accessibility, or strategic area value. Indeed, in this case, an analysis is required to integrate various criteria, thus serving as the basis for a decision as the best choice. The research method is presented descriptively, explaining the determination of the scale for recommending maintenance of district roads. The data collection technique is carried out using primary data in the form of documentation photos of each road section and road condition data assessed using the Road Condition Index (RCI) method or road roughness index, as well as secondary data consisting of road inventory data, road condition data, accident data, area size data, socioeconomic data, and maps. The fulfillment of the Minimum Service Standards (MSS) for roads is then calculated based on the collected data. This includes both the MSS for individual road sections and the MSS for the road network. The fulfillment of the road network's MSS is divided into three aspects: accessibility, mobility, and safety. Based on the analysis of the MSS, it is categorized into three recommendations: "urgent," "immediate," and "postponed." After obtaining the recommendations for each road section, they are presented as a map. After obtaining the research results, two road sections fall under the "urgent" recommendation for road maintenance. For immediate recommendations, there are 15 road sections. Meanwhile, 44 road sections are included in the delayed recommendations for road maintenance to be carried out.
