Abstract

In order to do bearing capacity and slope stability analysis of rock, determination of physical and mechanical parameter of the rock is needed. The objective of this study is to determine the mechanical parameter of the rock using RMR and GSI method. Result of this study are rock in Melasti beach area is classified into fair rock with range of GSI value of 35 to 45. Mechanical parameter of the rock using RMR method are f = 25 – 35 and c = 200 KPa – 300 KPa and mechanical parameter using GSI method is f = 24 – 29 and c = 256 KPa – 330 KPa.

Abstract

Birobuli is located in South Palu, which has highly vulnerable to earthquakes. One of the phenomena that usually occur after an earthquake is liquefaction which causes significant damage and loss of life. Furthermore, all the infrastructure is required to analyze the effect of external load and potential hazards. This research aims to investigate the liquefaction potential in Birobuli, South Palu. The method was divided into two categories: grain size distribution analysis and empirical formula based on CPT data. The result presented a similar trend in grain size analysis which consist of all the range in the potential to liquefaction, while the CPT result describes the same meaning. The CPT 1 result showed SF<1 between 0-5m and 9-11m, while CPT 2 had fluctuating data in ranges between 0.18-2.00 in 0-4m, SF under 2 in 6-8m and 9-11m. This study was expected to provide information for local government as disaster mitigation for Birobuli Area.

Abstract

In Indonesia, earthquakes occur very frequently. As a result of the earthquake, the safety of building structures against earthquakes really needs to be taken into account in the analysis of calculating the factor of safety. Apart from the effect of the earthquake on the superstructure, the effect of the earthquake on the substructure must also be considered. One of the substructure failures that can occur in the substructure due to an earthquake is a soil liquefaction where the soil experiences a loss/decrease in the bearing capacity of the soil as a result of the earthquake. This study used a quantitative method by conducting soil investigations and taking soil samples from the field. The results of the soil investigation will be used in calculating the potential for liquefaction of the soil layers and the axial bearing capacity of single pile foundations before and during liquefaction. At the study site, the dominant soil is loose sand with a high ground water table. The soil has the potential to experience liquefaction from a depth of 1.5 m to 13 m. This study modeled 2 pile models where both of them experienced a decrease in the axial pile bearing capacity respectively: 93% and 79%.

Abstract

Desa Adat Pejaten, Kabupaten Tabanan, Bali, memiliki Setra Tunon yang menjadi wadah kegiatan adat bagi masyarakat yang hingga kini senantiasa menjaga budaya warisan leluhur. Saat ini kondisi dinding penahan tanah pada Setra Tunon telah mengalami kerusakan dan diupayakan untuk dilakukan pembuatan serta perbaikan. Dalam upaya perbaikan dinding penahan tanah maka perlu dilakukan renovasi secara bertahap untuk mencegah keruntuhan tanah yang lebih parah. Untuk mendukung rencana tersebut, harus disertai dengan perencanaan yang baik berupa gambar rencana dan kelengkapannya. Kolaborasi tim Pengabdian Kepada Masyarakat dengan pihak mitra menjadi kunci dari keberhasilan kegiatan ini, sehingga permasalahan yang ada di lapangan dapat dicarikan solusinya secara bersama-sama. Keberhasilan target menyediakan capaian berupa gambar rencana struktur dinding penahan tanah diharapkan bermanfaat sebagai pedoman bagi desa adat dalam proses pengaturan, pembuatan Rencana Anggaran Biaya, serta dapat digunakan sebagai kelengkapan pengajuan proposal pengumpulan dana pengaturan setra Tunon
