Abstract

In construction work, construction management is needed. Construction management is the activity of planning, actuating and controlling projects using resources effectively and efficiently. The fundamental functions of construction management are planning, organizing, actuating and controlling. The Dittopad flats are a construction carried out by Pusziad TNI AD to raise personnel morale by providing a place to live. The purpose of writing is to analyze the application of construction management that occurred in the Dittopad Flats building construction project. The research method used was a literature review obtained by filling out a questionnaire with 50 respondents involved in the construction of the Dittopad Flats. The analysis was carried out using factors that influence the construction work system on basic management functions related to aspects of time, cost and quality. Based on factor analysis of the construction management work system, it was found that the most influencing function was planning with a value of 4.31. From the analysis of the actions taken by construction management at the Dittopad Flats, it was found that the one that had the most influence was the planning stage with a value of 4.26.

Abstract

Indonesia, as an agrarian country, heavily relies on the availability of water for irrigation, raw water supply, and electricity generation to support industrial growth. One of the government’s efforts to ensure water availability is the construction of dams, including the Cibeet Dam, which serves to reduce flooding, provide raw water, support irrigation, and generate electricity. A crucial component of a dam is the spillway, which must be capable of accommodating excess water, especially during extreme flood events. This study aims to re-evaluate the spillway design of the Cibeet Dam using a hydraulic and structural stability analysis approach. The data used includes the Cibeet Dam planning documents, topographic data, hydrological data, geotechnical data, soil investigation data, climatological data, and reservoir capacity data. The analysis covers stability against overturning, sliding, seepage, and soil bearing capacity under three water level conditions (empty, normal, flood), and assesses construction cost efficiency. The results show that reducing the spillway crest width by 0.5 m only increases the head (Hd) by 2 cm. The spillway with an ogee crest and USBR II stilling basin is considered stable, with safety factors >1.5 under normal conditions and >1.2 during seismic events. The soil bearing capacity is also deemed sufficient to support the structure under all water level conditions.

Abstract

Infrastructure development often faces slope stability challenges due to suboptimal soil conditions. One possible solution is the use of coconut coir as a soil reinforcement material to improve slope stability. This study analyzes the stability of embankment slopes reinforced with coconut coir using GeoStudio Slope/W 2012 software with the limit equilibrium Method and compares the results with Fahriani's (2016) study, which utilized Plaxis. The analysis was conducted on embankment slopes with varying percentages of coconut coir addition (0%–5%) using five limit equilibrium Methods: Morgenstern-Price, Spencer, Bishop Simplified, Janbu Simplified, and the Ordinary Method of Slices. The results indicate that all analysis Methods show an increase in the factor of safety (FoS) as the percentage of coconut coir increases. The comparison with Plaxis results shows a small FoS difference, ranging from 0.154% at 0% coconut coir to 1.397% at 5% coconut coir, with 0%–3% having a difference of less than 1%, indicating that both Methods provide relatively consistent results. The trend of increasing the factor of safety due to the addition of coconut coir remains similar in both software programs, reinforcing the effectiveness of coconut coir as a slope reinforcement material.
