Abstract

Considering that almost all buildings are built on or on the surface of the land, the land must have resistance to the building or the forces that work through the building by stabilizing the quality of the soil. This research aims to analyze the effect of using coffee grounds and wood charcoal on the geotechnical properties of clay soil. The main focus of the research is on changes in the Unsoaked CBR (California Bearing Ratio) value of clay soil due to the addition of coffee grounds and wood charcoal, both of which have binding properties such as coffee grounds which contain organic C (44.87%), N. (1.69%), K(2.49%), Na(0.04%), P(0.18%), pH (5.6) and wood charcoal can improve water and air circulation so that it can bind carbon and reduces soil swelling and shrinkage. The experimental method was used by mixing 10% wood charcoal and variations of coffee grounds 5%, 10% and 15% into clay soil samples. The results of testing the soil characteristics showed that the soil according to AASHTO was clay soil. Meanwhile, according to the USCS classification, this soil is included in the CH category (high plasticity inorganic clay). The results of the research showed that adding 10% Wood Charcoal to the original soil could increase the CBR value by 23.91%, while in the Wood Charcoal variation with the addition of Coffee Grounds by 5%, 10% and 15%, the CBR value decreased by 18.42%. 15.38%, and 9.57%.

Abstract

This study examines the "Review of Time and Labor Schedule Planning for the Bulo-Bungin Road Improvement Project in Enrekang Regency" which has the aim of knowing the duration of time and how much optimal labor is needed or required in the Bulo-Bungin road improvement project in Enrekang Regency. This research uses quantitative research to analyze data obtained from project sites and related documentation. The analysis method used in this research is Critical Path Method (CPM). Where Critical Path Method (CPM) is used to prioritize project activities or activities. The results showed that using the Critical Path Method to plan the project's time and labor schedule was more effective, because the duration of the work time was 8 days faster than before using the s-curve says it takes 140 days.

Abstract

Water plays a very important role in meeting human needs. The water supply in Lompo Tengah Village has not been able to reach all residents evenly, so it is necessary to plan clean water supply system. This study aims to plan clean water supply system in Lompo Tengah Village to public hydrants, which can meet water needs for the next 20 years. The methods used in this study include population projections, clean water requirements, and piping network simulations using Epanet 2.0. The results analysis projected population growth of Lompo Tengah Village for the next 20 years, calculated using the arithmetic method, reached 3,541 people, which was then reduced so that the number served was 142 people with water demand 0.586 liters/second and peak demand 0.88 liters/second. water source used Waenungnge' spring with flow 6.3528 liters/second. The clean water planning system is carried capturing spring using 73.5 m3 capacity catchment tank, then channeling through 35 milimeters diameter transmission pipe with the help pump to 13.2 m3 capacity reservoir, after which the water is distributed by gravity to 3 public hydrants. Based on analysis distribution piping system using Epanet 2.0, the pipes used PVC pipes with diameter of 25 millimeters.

Abstract

The potential of the Cabbue Dam is located in Cabbue Ompo village, Lalabata sub-district, Soppeng Regency, South Sulawesi Province. The water source for this dam will be supplied from the Tinco Dam. The Cabbue Dam area in Soppeng Regency plays an important role in the availability of population resources, especially in the aspect of agricultural irrigation and food security in South Sulawesi Province. This study aims to determine the safety factor value of the Cabbue Dam against shear and overturning, which is the main requirement in determining whether the dam can be said to be stable or not. To analyze the stability of the weir structure, a research method is carried out in the form of calculating the forces acting on the weir structure, then the forces acting on the structure are analyzed and their stability is controlled against the safety factors. In the stability analysis of the Cabbue Dam, it was obtained under normal water conditions that the stability results against overturning were Sf = 24.29 > 1.5 and stability against shear was Sf = 10.14 > 1.5. Meanwhile, in flood conditions, the stability results against overturning are Sf = 29.54 > 1.5 and stability against sliding is Sf = 7.73 >1.5, where the SF value is > 1.5. Based on the safety values obtained, it can be stated that the stability control of the Cabbue Dam building meets the requirements and is safe.

Abstract

Flooding issues in Makassar City remain a major concern that requires government attention. The Makassar City area, particularly during the rainy season with high rainfall, often coincides with the occurrence of the highest tidal surge in the Makassar Strait, which blocks the flow of the Tallo River at its mouth. The current river cross-section is unable to accommodate the discharge coming from the upstream, causing overflow that inundates residential areas and agricultural land. This study aims to determine the storage capacity and evaluate the effectiveness of the Nipa-Nipa regulation pond in flood management in Makassar City. A quantitative research method with a descriptive approach was used, presenting field survey data systematically and factually while establishing the relationship between the objects being studied through descriptive narration. The results of the study indicate that the storage capacity of the Nipa-Nipa regulation pond is 0.051231 m³/second. Furthermore, the effectiveness of the Nipa-Nipa regulation pond in handling flood discharge is measured at the peak discharge of Q2 years, which is 491.31 m³/second, with a time interval of 130 minutes. At the peak discharge of Q100 years, the value reached 1,131.94 m³/second, with a time interval of 56 minutes. Based on these analyses, the effectiveness of the Nipa-Nipa regulation pond’s capacity decreases at specific return periods, influenced by factors such as rainfall intensity.

Abstract

Construction projects heavily depend on efficient human resource utilization. Decreased productivity is a common issue, leading to project delays and increased costs. This study aims to analyze labor productivity in the installation of Reinforced Concrete Pipe (RCP) drainage in Green River View (GRV) Tanjung Bunga. This research employed a six-day field observation. Productivity data was analyzed using the Labor Utilization Rating (LUR) method to measure time efficiency, supplemented by interviews to identify qualitative factors. The average LUR was 53.20%, categorized as fairly efficient. Productivity fluctuated daily, influenced by factors such as weather, worker tardiness, differences in work tools, smoking habits, team coordination, and supervision quality. The work group with high discipline and modern tools showed the highest LUR. LUR proved to be an effective indicator for measuring work efficiency and management performance. This study recommends improving time management, standardizing tools, and enhancing supervision to boost overall project productivity.
