Abstract

Changes in land use in an area greatly affect water absorption. Inundation occurred in Ilir Timur II Subdistrict, Palembang City due to lack of maintenance of drainage channels and changes in land conversion which was originally land into a water catchment area, now it is a concrete or residential area. During the rainy season, water will fill residents' spaces in the form of puddles and floods, which will continue to increase surface runoff in the area. The impact of the inundation is very disturbing and detrimental to various parties. The purpose of this study is to determine the peak discharge, analyze existing drainage, and plan a new secondary drainage design. The data used are primary data, namely channel length measurement data, channel slope, and existing channel dimension measurement data. While the secondary data used is in the form of 10-year rainfall data obtained from two rain posts, namely the rain post in Sako District and the rain post in Ilir Barat I District, as well as land use data in the Fruit Watershed of Palembang City covering an area of 1222.89 hectares. Then carry out an analysis of changes in land use currently and calculation of peak discharge to plan the dimensions of the new secondary drainage channel. The current peak discharge (Qp) calculation results in the studied area are 24.4 m3/s. For the calculation of channel dimensions, it is planned to have a rectangular cross-section with channel dimensions at sta 0.00 - 672.80 m, namely the channel dimension height is 4.5 m, the channel width is 4.5 m, and the guard height (f) is 0.30 m. From the results of analysis and calculations it is known that with the dimensions of the new drainage design there will be no runoff along the secondary canal. It is hoped that this can be a reference in planning the drainage rearrangement in Ilir Timur II District to reduce frequent inundation.

Abstract

The project is a series of sensitive work mechanisms because each aspect of the project is interconnected with each other. The purpose of this research is to determine the planned duration, critical path activities, and probability in the implementation of the Dexa Medica warehouse construction project in Palembang. Primary data used for estimation of work time, while secondary data used time schedules (S-curve) and work plan drawings. The methods used are the Critical Path Method (CPM) and the Program Evaluation and Review Technique (PERT). The planned project completion duration using the CPM calculation method is 39 weeks. The activities known to be on the critical path are preparation, earthworks and others on the 1st floor, concrete work on the 1st floor, architectural work on the 1st floor, site development, and genset room work. The planned project completion duration using the PERT calculation method is 40.2 weeks. The probability (Probabiliti) with the PERT method is found to be 0.7324, meaning that there is a 73.24% probability that the project will be completed within 41 weeks.

Abstract

Lake Normalization is a job that aims to improve the structure of the lake shape by moving sedimentation in the lake so that the lake volume increases and can accommodate more water capacity. Lake normalization work uses excavator heavy equipment with hitachi and sumitomo brands. The purpose of this study is to determine the productivity of excavator heavy equipment using the analysis method of PERMEN PUPR No. 28/PRT/M/2016 and determine the number of heavy equipment needed in lake normalization work. Based on the results of the analysis that has been done, it is known that the volume of the lake is 98,350 m³ with hourly productivity of hitachi brand heavy equipment 93.72 m³ / hour and productivity of sumitomo brand heavy equipment 84.35 m³ / hour and the heavy equipment needed in lake normalization work is 10 units consisting of 5 units of hitachi brand excavators and 5 units of sumitomo brand excavators.

Abstract

Road construction projects undertaken by the Prabumulih City Government involve contractors as service providers. Therefore, project cost evaluation is required to determine whether contractors obtain a profit or incur a loss during implementation. This study aims to determine the Project Implementation Budget (RAP) based on actual material prices, labour wages, equipment costs, and field conditions, and to compare it with the Cost Budget Plan (RAB) for the Nigata Road Construction Project in Sukajadi Subdistrict, Prabumulih City. Primary data were obtained through field measurements, calculation of work volumes, and preparation of the cost estimate for Segment 2. Secondary data consisted of the project RAB, design drawings, the 2023 Unit Price Analysis, and the research location map. The RAB and RAP were calculated using the method applied by the Prabumulih City Public Works and Spatial Planning Agency, particularly in determining coefficients for each work item. The results showed that the RAP for the Nigata Road Construction Project amounted to IDR 862,024,101.46. The comparison between the RAB and RAP indicated a difference of 14.986%. This difference may represent the contractor’s potential profit margin, depending on actual expenditures and conditions encountered during project execution in the field and effective management of available project resources.
