Abstract

Menurut Direktorat Jenderal Minyak dan Gas Bumi (Ditjen Migas), LPG (Liquefied Petroleum Gas) adalah gas bumi yang telah diproses melalui pencairan. Gas ini terdiri dari bahan utama butana (C4H10) dan propana (C3H8). LPG dapat dihasilkan dari kondensasi gas bumi dari kilang minyak bumi atau melalui proses absorpsi dan kriogenik. Ada kemungkinan kebocoran gas saat menggunakan LPG, yang dapat membahayakan pengguna. Gas bocor yang tidak terdeteksi menyebabkan kebakaran seluruh dapur rumah. Gas elpiji menyebar karena tekanan gas yang tinggi saat bocor. Oleh karena itu, penulis akan menggunakan mikrokontroler ESP8266 dan sensor MQ2 yang menggunakan metode Triple Modular Redudancy (TMR) untuk membuat sistem yang dapat mendeteksi kebocoran gas LPG. Hasil dari pengujian sistem tersebut ialah, sensor 1 dan sensor 3 masih terdeteksi dengan lancar.Sedangkan pada sensor 2, terkadang nyala dan mati sekitar 9%-6% kemungkinan error.

Abstract

Recidivism remains a significant challenge in the social reintegration of former prisoners, particularly due to persistent social and economic pressures after release. This study aims to analyze the role of mosque-based communities in providing religious guidance as a mechanism for preventing recidivism among former prisoners in Jakarta. This research employs a qualitative case study approach, using unstructured interviews and participant observation involving three former prisoners and one mosque community mentor. Data analysis is conducted using General Strain Theory to examine the relationships among post-release pressures, emotional responses, and the tendency to reoffend. Findings indicate that former prisoners experience ongoing economic difficulties and social stigma, which increase vulnerability to recidivism. Mosque communities serve as alternative social spaces that offer religious mentorship, social support, and adaptive coping mechanisms to address these pressures. Religious guidance contributes to emotional regulation and the development of more constructive life orientations. This study concludes that mosque-based communities serve as effective informal social actors in supporting social reintegration and preventing recidivism among former prisoners.
