Abstract

Indonesia is intensively developing various infrastructure such as buildings, mosques, roads, bridges, dams and much more. Detailed planning is needed so that construction runs smoothly and results are maximum, including planning the budget (RAB). One method that can help identify significant costs in construction projects is the Cost Significant Model Method. The Cost Significant Model method is a cost analysis method that can be used to identify significant costs in construction projects. This method uses multiple linear regression analysis. In Indonesia, building district roads is a priority to improve connectivity and community welfare. Applying the Cost Significant Model in the Garut district road project is very important for efficient cost management. The aim of this research is to identify significant cost factors in district road projects and analyze the effect of implementing the Cost Significant Model on project cost management in the region. The research results show that the cost significant model provides accurate cost predictions with a coefficient of determination of 0.943, indicating a significant influence of variables on project costs. The variables Asphalt pavement division (X4) and structure division (X5) have a significant influence on project costs, so they can be prioritized to manage risks and reduce the impact of unexpected costs. The conceptual cost estimation model from this research is Y = -339907740.45 + 380172.81 (X4) + 117874.24 (X5). Testing the validity of this model shows that the cost estimation using this model is more accurate than using the average price per square meter times the building area. The Cost Significant Model method is an effective tool for managing road project costs in Garut Regency. This can help project managers predict costs more accurately and identify factors causing cost increases.

Abstract

Tannery sludge waste is solid waste produced by the leather tanning industry. This waste is B3 waste because it can cause itching on the skin, health problems and give off an unpleasant odor. However, this waste also contains the same compounds as cement, namely iron and aluminum, so it can be used as a substitute material for clay soil with the aim of increasing the soil's bearing capacity. Clay soil is considered poor soil if it is to be used as the basis for construction. Therefore, research was carried out on the physical properties of clay soil mixed with tannery mud waste. The method used is experimental, where the physical properties of clay soil are tested, consisting of water content, bulk density, specific gravity, sieve analysis, and Atterberg limit, plus a mixture of tannery mud waste in proportions of 0%, 25%, 50%, and 75%. % of soil weight. The results of the research showed that clay soil with the addition of tannery sludge waste resulted in a decrease in water content; increase in unit weight and specific gravity; the proportion of fine grains decreases and coarse grains increase; as well as an increase in the plasticity index.

Abstract

Pasir Bajing TPA is the only TPA with a Sanitary Landfill system in Garut Regency. The increasing burden of landfills along with population growth makes the feasibility of the Pasir Bajing landfill interesting to study. This research aims to analyze the technical feasibility of the Pasir Bajing TPA and evaluate the feasibility of waste storage buildings in the Sanitary Landfill system at the Pasir Bajing TPA. The research method used is descriptive evaluative. Data obtained directly through field surveys. The technical feasibility of the landfill was analyzed based on SNI-03-3241-1994, while the feasibility of the waste storage building was analyzed using SNI 03-6154-1999. The research results show that the Pasir Bajing TPA technically does not fully meet the requirements according to SNI-03-3241-1994 because there are no monitoring wells, leachate collection buildings, drainage is not yet effective and a new weigh bridge has been built. The evaluation results of the waste storage building show that in terms of dimensions it meets the criteria of SNI 03-6154-1999. Based on the calculation of the capacity of the waste holding building, it is able to accommodate waste for the next 2 years, however, in terms of strength, it is not suitable because the height of the embankment and the height of the embankment or gabions do not match the strength to hold the embankment in the event of a shock or landslide.

Abstract

Balok beton bertulang sebagai elemen struktur yang berfungsi menahan lentur dan geser dimana parameter utama untuk menentukan kuat lentur dan geser balok beton bertulang meliputi: dimensi penampang, mutu beton, mutu baja tulangan, ukuran baja tulangan dan jumlah baja tulangan yang digunakan. Dalam konstruksi parameter tersebut umumnya memiliki batasan minimum, seperti halnya dengan jarak tulangan dan dimensi penampang kecil. Untuk mendapatkan elemen struktur dengan penampang kecil namun memiliki kekuatan yang besar, dengan jarak tulangan yang kecil karena luas tulangan yang dibutuhkan besar, maka perlu dilakukan penempatan tulangan dengan cara bundel. Tujuan penelitian ini untuk mengetahui nilai kuat lentur dan geser balok beton tulangan bundel TP 4Φ6 dan balok beton tulangan tunggal Φ12 yang memiliki proporsi luas penampang tulangan yang sama. Analisis dilakukan dengan metode analisis teoritis dengan data yang diperoleh dari hasil eksperimen terdahulu. Berdasarkan hasil analisis diperoleh nilai kuat lentur rata-rata balok tulangan bundel TP 4Φ6 = 8,53 kN.m, dan balok tulangan tunggal Φ12 = 11,31 kN.m. Nilai kuat geser rata-rata balok tulangan bundel TP 4Φ6 = 58,88 kN, dan balok tulangan tunggal Φ12 = 57,92 kN. Dari hasil eksperimen dan analisis diperoleh perbedaan kuat lentur balok tulangan bundel TP 4Φ6 sebesar (6,36%) dan balok tulangan tunggal Φ12 sebesar (48,62%). Sedangkan kuat geser balok tulangan bundel TP 4Φ6 diperoleh hasil yang sama yaitu 58,88 kN dan balok tulangan tunggal Φ12 diperoleh perbedaan sebesar (0,03%).

Abstract

Road infrastructure is one of the most strategic transportation infrastructure facilities. This is supported by road stability which is supported by road maintenance and repairs. Handling road repairs cannot be separated from funding from the budget of each region, especially in the district. Budget limitations affect road repairs, so there needs to be priority handling. The aim of the research is to determine the criteria that are the basis for prioritizing road maintenance and to develop a priority order for district road maintenance based on the availability of budget allocations in Banyuresmi District, Garut Regency. The research methodology uses a descriptive evaluative method, analyzed using the Analytical Hierarchy Process. The results of respondents' assessments of road maintenance handling show that the priority criteria consisting of the type of road damage factor have an influence of 31.9%; policy factors influence 31.7%; traffic condition factors influence 23%; and the service condition factor has an influence of 13%. The priority order for handling Regency road maintenance is based on the availability of budget allocations in Banyuresmi District, Garut Regency, for the Pasirmuncang - Cipicung, Tanjung - Maleer, Cipicung - Wanaraja, Cibudug - Cipicung, Bojongsalam - Menger, Jager - Jolok/Cipicung, and Warungpeuteuy - Kiaralawang roads.
