Abstract

The purpose of the Yogyakarta - Bawen Toll Road construction was to improve connectivity between Yogyakarta and Semarang. However, during its construction, soft soil problems were found, so Prefabricated Vertical Drains (PVD) were installed. The installation of PVD aims to increase the rate of pore water discharge from the soil, thereby compacting it and enhancing its bearing capacity. Changes in soil material parameters also accompany this increase in bearing capacity. This study was conducted to analyze the effect of PVD installation on the physical and mechanical properties of the soil. The analysis was conducted by comparing soil investigation data before and after the PVD installation. Soil sample data were collected from the Yogyakarta-Bawen Toll Road, STA 4+500, specifically at BH 17. The physical properties under review are water content, wet unit weight, soil specific gravity, Atterberg limits, and changes in particle composition as determined by grain size analysis. Meanwhile, changes in the mechanical properties of the soil include pre-consolidation pressure, compression index, recompression index, consolidation coefficient, and volume compressibility. Undrained shear strength parameters were measured using an unconfined compression test to identify the soil's bearing capacity. The results show changes in physical and mechanical parameters before and after PVD installation. Overall, the most critical aspect of the accelerated consolidation method for physical parameters is a decrease in water content of 13% to 37% compared to the pre-PVD installation condition. Meanwhile, changes in the consolidation parameters, as well as a decrease in unconfined compressive strength of 2% to 12%, are also observed. This occurs for various reasons, one of which is the relationship between the completion time of the consolidation process and the consolidation process. However, the soil classification remained the same, according to the USCS, as a very stiff soil type

Abstract

Kondisi akses masuk pemakaman umum Dusun Setro, Jembrak, Pabelan selama ini hanya berupa jalan tanah dengan tanaman rindang di kanan kiri jalan. Seiring dengan banyaknya warga perantau yang ziarah ke makam tersebut, warga sekitar mulai berupaya menggalang dana dan bergotong royong untuk membuat akses masuk ke pemakaman menjadi lebih baik dengan membuat jalan, saluran air, dinding penahan tanah, serta gapura. Tim Pengabdian kepada Masyarakat Departemen Teknik Sipil membantu memberikan pendampingan pembuatan dinding penahan tanah serta gapura pada daerah akses masuk ke pemakaman Dusun Setro, Jembrak tersebut. Kerjasama dan koordinasi yang baik antara Tim Pengabdian kepada Masyarakat Departemen Teknik Sipil bersama-sama dengan warga Dusun Setro, Desa Jembrak diwujudkan sehingga permasalahan yang ada di dalam masyarakat dapat tertangani dengan baik. Struktur dinding penahan tanah yang dibuat berupa dinding pasangan batu kali di sebelah kanan dan kiri jalan yang akan dibuat. Ketinggian dinding disesuaikan dengan kontur tanah untuk dapat menahan longsoran tanah ke badan jalan, sedangkan gapura dibuat dari material beton bertulang. Dengan selesainya program Pengabdian kepada Masyarakat Batch 2 ini bersamaan dengan selesainya pekerjaan pembuatan akses jalan masuk pemakaman umum Dusun Setro sehingga diharapkan dapat bermanfaat bagi Masyarakat Dusun Setro maupun warga sekitar desa
