Abstract

Land use refers to an organized spatial management pattern through institutional arrangements for the benefit of the community in a fair manner. Land use maps serve as an analysis tool that helps determine the area of the area, monitor development, and identify land use patterns. This study aims to produce land use map planning in Sematang Borang District by utilizing manual measuring devices and GPS.  The research method used by the Focus Group Discussion (FGD) method was used to obtain additional information from related agencies. The process of planning land use maps in Sematang Borang District begins with the identification of problems and regional objectives, followed by field surveys to collect primary and secondary data. The results will be a reference for more targeted and sustainable land use policies. The results of the land use map planning research comprehensively describe the allocation of space for various functions, such as settlements, industries, green open spaces, and conservation. Environmental, social, and economic aspects are the main focus in this planning, with the aim of supporting sustainable management of the area. The environmental aspect pays attention to the sustainability of natural resources and ecosystem protection, while the social aspect emphasizes an inclusive approach to local communities for well-being.

Abstract

This study aims to compare the Dynamic Cone Penetrometer (DCP) value with the laboratory California Bearing Ratio (CBR) value on soil classified as SC according to USCS and A-2-6 according to AASHTO. Soil samples were taken from the area of the Balai Besar Pelaksanaan Jalan Nasional (BBPJN) South Sumatra at a depth of ±60 cm in three test points. The laboratory tests included natural moisture content, specific gravity, Atterberg limits, sieve analysis, and standard Proctor compaction. The compaction test results showed an optimum moisture content of 18.06% and a maximum dry density of 1.70 g/cm³. The CBR values were obtained from laboratory testing, while the DCP values were measured through dynamic cone penetration on the same samples. Correlation analysis using four methods (PUPR, ASTM, Kleyn, and Zumrawi) indicated varying results. The PUPR method produced the most consistent estimates compared to laboratory data, while ASTM D6951-03 achieved the highest coefficient of determination (R^2 = 0.9743). The Kleyn method remained applicable though less accurate, whereas the Zumrawi method showed significant deviations and was unsuitable for the soil conditions in this study. These findings confirm that the DCP test can serve as a rapid and efficient alternative for estimating CBR values of subgrade soils with similar characteristics.

Abstract

Kinerja perkerasan jalan sangat dipengaruhi oleh kualitas material tanah dasar. Tanah lempung kurang baik digunakan sebagai tanah dasar karena mempunyai daya dukung yang rendah dan sensitif terhadap perubahan kadar air akibat curah hujan maupun genangan. Makalah ini menyajikan hasil studi laboratorium mengenai pengaruh penambahan abu terbang dan kapur  terhadap tanah lempung untuk dijadikan material tanah dasar jalan perkotaan.  Nilai Plastisitas dan California Bearing Ratio (CBR) digunakan sebagai indikasi peningkatan kekuatan tanah dasar pada kondisi tidak direndam dan direndam. Dalam penelitian ini dilakukan penambahan 5% kapur dan 5 – 30% abu terbang. Hasil pengujian menunjukkan nilai optimum penambahan abu terbang sebesar 25%. Uji batas Atterberg menunjukkan bahwa penambahan 5% kapur dan 25% abu terbang menurunkan indeks plastisitas tanah dari 23,60% kepada 17,72%, sehingga dapat mengurangi pengaruh air terhadap tanah. Hasil pengujian CBR menunjukkan bahwa penambahan 5% kapur dan 25% abu terbang memberikan nilai CBR tertinggi sebesar 8,27% dan nilai pengembangan terendah yaitu 0.84%.

Abstract

In Southeast Sulawesi, the Konawe Regency–Kendari City–Sampara District corridor experienced severe flooding in 2019, resulting in road inundation and multiple landslides, including a major failure at Km 22. This study investigates the mechanisms and contributing factors of the landslide by modeling the effects of river water level fluctuations, groundwater level changes, and scouring on slope stability using Slope/W software. The analysis reveals that rising river water levels increase the slope’s safety factor, whereas sudden drawdown conditions significantly reduce it, potentially triggering slope failure.Keywords: Failure, slope stability, Safety factor
