Abstract

Water availability is a key factor in the sustainability of small-scale livestock farming. Tambong Village, Kabat District, Banyuwangi Regency, faces limited access to water for livestock needs, particularly during the dry season, as well as low community knowledge regarding water supply and distribution technologies. This community service program aims to develop efficient water source infrastructure and enhance community capacity in managing livestock water supply. The methods employed include site surveys and preliminary studies, technical planning, construction of shallow wells with gravity-based distribution systems, and training and socialization on water supply technology. The results indicate that the water infrastructure—consisting of a dug well, storage tank, piping network, and electrical system—has been successfully constructed and operates properly. Evaluation results show that the community’s level of understanding reached 85.17%, categorized as very good. This program contributes to improving livestock productivity and supports food security programs at the village level.

Abstract

Peat soils, which are mainly composed of semi-decayed plant remains, usually have high compressibility and low bearing capacity. The high compressibility and low bearing capacity mean that peat soil must be improved if construction is to be built on it. Research was conducted to find a method for soil improvement. Improvements were made by reinforcing the peat with bamboo stakes using the finite element method modeling. In the results of modeling and calculations using software based on the finite element method, the Ambarawa peat soil, before reinforcement with a bamboo stakes at a 5-day time interval, obtained a total deformation value of 7.18 m. After a 5-day interval, the soil collapsed due to its low bearing capacity, preventing further calculations and leaving the safety number unknown. In the Ambarawa peat soil after reinforcement with a bamboo stakes planned 8 m long bamboo stakes and a distance of 1 m between bamboo stakes based on calculations using finite element method modeling at a time interval of 5 days, the total deformation value was obtained at 3.98 m, a time interval of 10 days at 4.46 m, a time interval of 15 days at 4.46 m. Based on the known deformation value, the maximum safety value of this modeling was obtained at a time interval of 30 days, with a value of 1.173.

Abstract

High-plasticity clay soil commonly exhibits low bearing capacity and therefore requires an effective, economical, and applicable reinforcement method. This study aims to analyze the effect of bamboo pile length variation on the unconfined compressive strength of clay soil from Kedungdandang Hamlet, Tapanrejo Village, Muncar District, Banyuwangi Regency. Disturbed soil samples were collected at a depth of 70 cm and characterized through sieve analysis, water content, specific gravity, unit weight, and Atterberg limit tests. Mechanical performance was evaluated using the Unconfined Compression Test on untreated clay and clay reinforced with bamboo piles measuring 3 mm in diameter, 1.25 cm spacing, and lengths of 3.5, 5, and 7.5 cm. The soil was classified as high-plasticity clay, with a liquid limit of 81.81% and plasticity index of 46.96%. The average UCS increased from 26.60 kPa to 32.66, 36.61, and 47.19 kPa. The 7.5 cm piles provided the highest improvement, 77.41% over untreated soil.

Abstract

Tanah lempung bila dalam keadaan kering akan bersifat keras, dan jika basah akan bersifat lunak plastis, dan kohesif, mengembang dan menyusut dengan cepat. Tanah pada Desa Tapanrejo, Kecamatan Muncar, Kabupaten Banyuwangi dibuktikan munculnya fenomena ekspansif yang menyebabkan kerusakan konstruksi diatasnya berupa keretakan pada dinding rumah dan elevasi tanah yang tidak merata. Pada penelitian ini akan dilakukan penambahan bahan stabilisasi tanah lempung dengan menambahkan campuran kapur dan abu ampas tebu menggunakan pengujian dengan metode uji kuat tekan bebas atau UCT (Unconfined Compression Test) dimana metode pengujian ini akan langsung menghasilkan tekanan yang langsung memberikan pendekatan terhadap daya dukung kualitas tanah. Pengujian ini bertujuan untuk mengetahui pengaruh campuran kapur dan abu ampas tebu terhadap kuat tekan bebas tanah sebagai salah satu alternatif perbaikan tanah dengan dibuat variasi campuran kapur sebesar 10%, 12 %, dan 14% untuk abu ampas tebu sebesar 10%, 12 %, dan 14%. Berdasarkan hasil pengujian kuat tekan bebas dimana pada variasi campuran kapur dengan presentase 10% menghasilkan nilai kuat tekan tertinggi dari semua variasi dan bisa dikatakan bahwa pada campuran kapur 10% dapat meningkatkan nilai daya dukung tanah dimana pada pencampuran tanah dan kapur dengan presentase 10% mendapatkan nilai qu sebesar 106,99 kN/ (kPa). Pada pencampuran tanah asli dan abu ampas tebu 10 % diperoleh nilai tertinggi dengan hasil nilai qu sebesar 77,07 kN/ (kPa). Dan pada pencampuran tanah asli + kapur + abu ampas tebu nilai tertinggi yaitu pada variasi 10% sebesar 78.58 kN/ (kPa).

Abstract

Songgon District is one of the areas in Banyuwangi Regency that has a high vulnerability to landslides due to steep slope topography, high rainfall, and tectonic and volcanic activity from Mount Raung. This study aims to analyze slope stability, identify landslide-prone zones, and develop an appropriate disaster mitigation strategy matrix in the area. The research method used is an integrative approach that combines numerical modeling based on the 3D Finite Element Method, and Geographic Information System (GIS)-based spatial mapping with Kriging interpolation techniques. Slope stability analysis was conducted at 15 critical review points spread across the Songgon area. The modeling results show significant variations in slope stability levels, where several critical points show safety factors below the safety limit FK < 1.25. Based on the spatial zoning generated through GIS Kriging, the study area is mapped into three vulnerability zones: low, medium, and high vulnerability zones. As an output of the mapping and analysis of geotechnical parameters, a comprehensive disaster mitigation matrix was prepared, including structural recommendations (such as slope reinforcement and drainage improvements) and non-structural recommendations (such as community-based early warning systems and evacuation route mapping) to minimize the risk of future disaster impacts.

Abstract

Desa Pakistaji, Kabupaten Banyuwangi, memiliki aktivitas produksi bata yang masih mengandalkan proses konvensional berbasis tanah liat dan pembakaran, sehingga memunculkan persoalan efisiensi produksi, kualitas produk yang tidak seragam, serta isu lingkungan akibat konsumsi energi dan emisi. Di sisi lain, limbah jerami padi di wilayah sekitar masih belum termanfaatkan optimal dan sering dibakar terbuka, yang berdampak pada kualitas udara dan kehilangan potensi nilai tambah. Kegiatan pengabdian ini bertujuan menerapkan teknologi BERATON–Cellular Lightweight Concrete (BERATON-CLC) berbasis jerami dan abu sekam padi serta mengevaluasi efektivitas transfer teknologi kepada pengrajin bata Desa Pakistaji, Banyuwangi. Kegiatan dilakukan melalui sosialisasi, demonstrasi, praktik produksi, pengendalian mutu sederhana, dan evaluasi pre-test–post-test terhadap 11 peserta. Skor rata-rata meningkat dari 51,18 menjadi 86,18; paired sample t-test menghasilkan t(10)=10,606 dan p<0,001 dengan Cohen’s dz=3,20. Rata-rata N-Gain individual sebesar 0,6989 termasuk kategori sedang dan mendekati tinggi, sedangkan keterampilan produksi (0,7867) dan pengetahuan produk (0,7516) berkategori tinggi. Kajian mutu menunjukkan formula tanpa ASP memiliki estimasi kuat tekan tertinggi 1,39 MPa, sedangkan ASP 10% memiliki resapan terendah 7%. Panel BERATON-CLC dengan jerami 8% mencapai kapasitas transversal 19,61 kN pada umur 14 hari. Program meningkatkan kapasitas mitra, sedangkan optimasi formula dan pengujian kuat tekan unit berbasis jerami masih diperlukan.
