Abstract

The problem that occurred in the ABC Flats Construction Project in Banjarbaru was that the project land was quite narrow. So if there is a large scale accumulation of material waste and lack of material management it can result in delays in the construction process, especially the mobilization and demobilization of tools. The aim of this research is to determine materials that cause large waste costs and the factors that cause them, as well as possible strategies to minimize waste. The analysis method is carried out using Pareto, waste cost and fishbone analysis. Collecting data by means of observation and interviews or brainstorming on several similar projects. The results of the Pareto analysis (80/20) show that there are two materials that contribute large costs, namely iron and concrete. The material that has the potential to generate large waste costs in the ABC Kalimantan Flats Construction Project as of the 21st week is ready mix concrete. The contribution of waste value per square meter is 0.073 m3 with a waste cost of 0.003% of the contract value. Based on the fishbone analysis, it was found thst the factors causing waste are a narrow location, stacking of moving materials, workers placing material carelessly, length of reinforcement that is not uniform, simplification of the shape of the pile cap structure, use of tools that do not match their function, number of orders that do not match, the rest of the concrete in the mixer, workers fatigue. Strategies to minimize waste of iron-concrete and ready-mix concrete materials are providing guidance to blacksmiths and workers, making access to tool distribution, using tools according to their functions, utilizing residual concrete, analyzing linear programs or barbending schedules. These results become considerations and suggestions in reducing the project budget due to the impact of material waste.

Abstract

This research intends to determine whether the capacity of existing drainage channels is still sufficient or not. The method of analysis used involved collecting rainfall data over the past 14 years (2010-2023) from the Class I Banjarbaru Climatology Station and obtaining the dimensions of the drainage channels from direct field measurements. From the results of the study, it was found that some of the drainage was unable to withstand the discharge plan, so redesign and new drainage design were needed. The planned channel dimensions for the redesigned drainage have a channel depth of 1 m and a planned width of 0.9 m. The planned channel dimensions for the new drainage have a channel depth of 0.9 m and a planned width of 0.7 m.

Abstract

Floods are one of Indonesia's most frequent natural disasters, especially in densely populated cities. Major floods in February 2023 hit Cempaka and Gunung Kupang Districts. To overcome this problem, the government built the Cempaka Embung and the Gunung Kupang Embung to control flooding and increase water infiltration into the ground. Land use changes upstream of the reservoir greatly affect the reservoir, especially land erosion and sedimentation that enter the reservoir body, which will reduce the performance of the reservoir in reducing flooding. Therefore, erosion and sedimentation analysis is needed to support better management in flood control in Cempaka District. The data used in this study are land use data, soil type data, topographic data, conservation data, and location photos are secondary data. In this study, the rate of erosion and sedimentation was calculated using the USLE method. Based on the results of the analysis, it was found that the erosion rate of the USLE method in the Cempaka Reservoir was 131.934 tons/ha/year, and the sediment rate was 38.0765 tons/ha/year. In the Gunung Kupang Reservoir, the USLE method erosion rate was 18,790 tons/ha/year, and the sediment rate was 6,057 tons/ha/year.Keywords: Watershed Erosion, Reservoir Sediment, USLE, Reservoir

Abstract

The Kampung Banjar Reservoir and Kebun Raya Reservoir were built to address the disrupted water catchment areas caused by land clearing for the development of the South Kalimantan Province Government office area in Banjarbaru. These two reservoirs are planned to function as water catchment areas, water tourism destinations, and raw water sources within the office areas. The water availability in the reservoirs is expected to remain stable. Therefore, a study on the water availability analysis of both reservoirs is necessary to ensure that the stored water can be utilized optimally and sustainably, particularly for tourism purposes. The research methodology includes data collection, data analysis, results, and discussion. The analysis phase involves evapotranspiration analysis, water availability analysis using the F. J. Mock method, and dependable flow analysis. Based on the flow simulation calculations using the F. J. Mock method, a 90% dependable flow was selected for raw water rEquationuirements. The largest dependable flow occurs in December, with a flow value of 0.1557 m³/second for the Kampung Banjar Reservoir and 0.2028 m³/second for the Kebun Raya.  Keywords: Water Availability, Dependable Flow, Kampung Banjar Reservoir, Kebun Raya Reservoir.

Abstract

Perubahan iklim dipengaruhi oleh kondisi cuaca yang tidak stabil sebagai contoh curah hujan yang tidak menentu, sering terjadi badai, suhu cuaca yang ekstrim, dan arah angin yang berubah drastis hingga akhirnya menyebabkan banjir atau tanah longsor. Permasalahan yang mendasar adalah kurangnya kesiapsiagaan atas bencana banjir yang terjadi di daerah Martapura, Kabupaten Banjar. Manajemen risiko merupakan kegiatan mendasar yang diarahkan untuk mengevaluasi skema untuk mengurangi risiko tetapi tidak untuk menghilangkan semua risiko, karena risiko dalam banyak kasus tidak dapat sepenuhnya dihilangkan. Pada pengabdian ini akan memberikan informasi mengenai risiko banjir dan genangan secara terintegrasi dengan memberikan analisis terhadap kesiapsiagaan terhadap kejadian banjir oleh masyarakat. Sehingga dapat memberikan referensi terkait mitigasi bencana banjir bagi SMPN 5 Martapura khususnya serta masyarakat Martapura pada umumnya.
