Abstract

Kabupaten Banyuwangi merupakan wilayah dengan aktivitas seismik tinggi yang menuntut penerapan desain struktur tahan gempa. Penelitian ini mengevaluasi kinerja seismik struktur gudang baja eksisting dengan sistem Ordinary Moment Frame (OMF) dan membandingkannya setelah dimodifikasi menjadi sistem Ordinary Concentrically Braced Frame (OCBF). Analisis dilakukan menggunakan metode Linear Time History Analysis (LTHA) pada ETABS v22, dengan input tiga data gempa historis (Chi-Chi, Miyagi, Tokachi). Hasil menunjukkan bahwa struktur OMF mengalami overstress pada elemen kolom (rasio tegangan D/C sebesar 0,951), rasio kelangsingan KL/r mencapai 205,49 (melebihi batas 200), serta simpangan antar tingkat sebesar 249,22 mm (2,6%), melampaui batas izin 143,077 mm. Setelah modifikasi ke sistem OCBF, nilai D/C turun menjadi 0,785, rasio KL/r menjadi 141,84, dan simpangan antar tingkat berkurang drastis menjadi 70,09 mm (0,7%). Dengan demikian, penambahan bracing terbukti efektif meningkatkan performa seismik struktur baja pada kawasan rawan gempa.

Abstract

This community service program aimed to empower farmers in Bambang Village, Wajak District, Malang Regency, to manage organic waste into compost as an effort to restore soil fertility in former sand-mining areas and promote sustainable agriculture. The program was carried out over two months, involving 20 farmers through three main stages: socialization, technical training, and evaluation. An educational-participatory approach was applied to enhance farmers’ knowledge and skills in compost production and application on horticultural land. The results showed a 40% increase in participants’ knowledge, successful production of high-quality compost, and noticeable improvements in soil structure after its application. In addition, farmers began reducing their dependence on chemical fertilizers and managing organic waste independently. This activity proved effective in improving farmers’ capacity while contributing to the rehabilitation of degraded land ecosystems and the development of sustainable agriculture in Bambang Village.
