Abstract

The foundation is a very important part of a structure that is not protected by air such as sediment. Basic foundation repairs aim to ensure that the soil stress that arises as a result of the dam's own weight, air pressure, earthquake forces and acting loads does not exceed the carrying capacity of the dam foundation soil at the bottom or on the left and right banks of the dam. In the Jlantah Dam Construction Project there were problems related to the dam foundation. Repairs to the Jlantah Dam foundation were originally designed using curtain grouting, but from the results of grouting tests on the riverbed the results were not able to reach the required airtightness (Lugeon) value. Considering that alluvial deposition and strongly weathered rock layers are still quite porous, it is necessary to repair the foundation specifically using a cut-off wall or diaphragm wall. The purpose of using a diaphragm wall is to strengthen the foundation when the body bends. The method used in making plastic concrete is laboratory testing to obtain results that comply with standards. The conclusion obtained from plastic concrete on barrier walls is in accordance with applicable standards.

Abstract

The Bakung Village watergate construction began in early September and concluded on October 9, 2023. If the physical construction of the water gate deviates significantly from the planned schedule, there is a concern that the project will be disrupted by high water flow in the fields. This situation could lead to the failure of the Bakung Village water gate project due to the high water volume in the fields. Additionally, supervision of the specifications and volume of each work unit is necessary to ensure that the constructed structure can be used properly and safely. Time and quality control are essential to ensure the project is completed successfully according to the contract. The method used for time control is the bar chart/graph. For quality control, the method involves comparing the actual work's specifications and volume of unit prices with the planning stated in the contract. Supervision and control are carried out by verifying the contractor's project results using documents and direct monitoring in the field. The total duration of the work is 40 calendar days. The contractor could carry out the work according to the technical specifications, and the volume of each work unit stated in the contract. Based on daily and weekly reports from the supervising consultant and field inspections, the Bakung Village water gate construction was completed according to the contract agreement.

Abstract

Floods occur when the overflowing water cannot be accommodated by the river and inundates the flat area around the river. Flood protection parapets are one method for dealing with flooding on the Jeroan River in Madiun Regency. The 300-meter-long parapet was built in 2019. However, water seepage outside the embankment caused landslides, which was a problem during maintenance. So, from 2020 to 2021, the handling of the Jeroan River is evaluated based on financial conditions and input from the work directors. The stability analysis method was carried out using Geoslope software under normal, earthquake and rapid drawdown conditions. The results of the research were carried out at a location in Gelonggong Village, which was evaluated with three conditions and the addition of simple concrete blocks. The results show the safety factor value for normal conditions is 1.80, earthquake conditions 1.32, and rapid drawdown 1.6. At this location, slope strength is not added because the location is far from residential areas, so it does not endanger residents. The results of the analysis carried out in Kedung Jati Village, where there were three conditions, strengthening gabions and adding flat plate concrete blocks, showed a normal safety factor value of 3.19, earthquake conditions 2.18, and rapid drawdown 3.07. In Warurejo Village, the normal safety factor value was 3.19, earthquake conditions 2.25, and rapid drawdown 3.20. In Babadan Lor Village, the normal safety factor value was 3.26, earthquake conditions 2.78, and rapid drawdown 3.20.

Abstract

The study of water balance is an analysis of the equilibrium between water demand (demand system) and water availability (supply system). Current conditions show that the water balance tends to become increasingly critical, leading to conflicts of interest in water use. Therefore, optimizing water allocation in a watershed (DAS) is necessary by considering water users and the regulations applicable within the administrative area where the watershed is located. The location of the water balance analysis research is in the Barito River Basin, which consists of the Barito Watershed, Kapuas Watershed, Maluka Watershed, and Tabanio Watershed. In this study, the Barito Watershed is the largest watershed within the Barito River Basin, crossing two provinces, namely Central Kalimantan Province and South Kalimantan Province. The aim of this research is to provide water balance calculations that can serve as a basis for developing water allocation concepts in the form of an annual water supply plan. The data used in the water balance analysis include spatial data, hydrological data, and walkthrough implementation data. The results of the water allocation modeling provide an overview of the extent to which water demand is met under existing conditions and can serve as a consideration if there is an increase in water utilization rates for each user in the future.

Abstract

Most coal mining activities in South Kalimantan apply the open pit method, which has the potential to produce acid mine drainage. As wastewater from coal mining activities, acid mine water has high acidity and metal content. Mitigation of the handling of acid mine drainage can be grouped into two processing techniques: active processing using conventional methods by neutralizing the acidity by applying quicklime. Still, in the end, this processing is considered very expensive, and passive processing is relatively cheaper but has limited processing capacity, so development with the Swampy Forest system is required. The acid mine drainage that has occurred and which has been collected in the post-mining lake is then channeled to the Swampy Forest system processing pond, which has been given organic material, and the specified types of hyperaccumulator grass and trees have been planted to change the water quality which does not meet the quality standard values to meet it. quality standard values under applicable regulations. The Swampy Forest system is proven to significantly improve water quality to meet applicable regulatory compliance requirements with a cheaper and environmentally friendly process.

Abstract

PT Adaro Indonesia is a leading energy producer company with a mining and coal business sector. PT Adaro Indonesia through its Coal Processing and Barge Loading (CPBL) division produces 5 types of coal which are differentiated by their CV value. In the process there are several things that cause operational stops, one of which is dust. Dusty is generated from the grinding process in crusher equipment with a total loss time in 2022 of 1951 minutes. Basically, the method used uses the PDCA method (plan, do, check, action). From the PDCA method, 3 root problems were obtained that needed to be resolved. Firstly, the material is dry due to the long dry season and extreme weather conditions, this requires maximizing the work of the sprayer system. The two new methods used are capable of carrying out distribution in accordance with the chemical budget forecast plan. Third, the machine used is modified in such a way as to improve the process of setting chemical doses and reporting automatically using a Scada system. From the results of this improvement, a reduction of 90.2% was obtained with NAB entering the category of quality standards permitted in accordance with PP No. 22 2021.
