Abstract

Pabrik Tahu Al-Jalil merupakan salah satu usaha rumah tangga yang terletak di Kec. Arjasa, Kabupaten Jember, Jawa Timur. Industri tahu ini selain dapat memberikan lapangan pekerjaan bagi masyarakat juga dapat menimbulkan pencemaran lingkungan. Potensi pencemaran lingkungan yang dapat ditimbulkan berupa pencemaran air. Dari permamasalah tersebut, didapatkan solusi untuk mengurangi dampak pembuangan limbah pada lingkungan sekitar dengan memanfaatkan limbah cair tahu dan kotoran ternak warga menjadi biogas dengan nama “Ware Gas” yang dilengkapi dengan sensor monitoring. Sasaran dari kegiatan ini adalah memberdayakan warga sekitar Pabrik Tahu Al-Jalil. Metode pelaksanaan kegiatan ini adalah perancangan reaktor biogas, pembuatan reaktor biogas, perancangan sistem monitoring, pembuatan sistem monitoring, sosialisasi dan demonstrasi alat. Hasil dari kegiatan ini adalah reaktor biogas yang telah dilengkapi dengan sistem monitoring aplikasi Blynk. Selain itu, memberikan pengetahuan masyarakat tentang bagaimana mengelola limbah tahu dan memanfaatkannya menjadi biogas.

Abstract

Essential oil is compounds that contained in plants and have many benefits. Basil is an aromatic plant that can produce essential oils. Essential oils can be extracted from basil leaves using Microwave Assisted Hydrodistillation (MAHD) method. To determine the efficiency of the MAHD method, it’s necessary to study the kinetics of the extraction method. It’s because kinetic studies can be used to identify the optimal point in the process where the highest efficiency is obtained, so the extraction process can be optimized. The aim of this research is to evaluate the suitable kinetic model for the basil leaf extraction process using the MAHD method. This extraction using 100 grams of basil leaves and 200mL aquadest, heated at various microwave power 150W, 300W, and 450W. The extractions were carried out for 70 minutes with 10 min intervals. The results showed that the largest oil yield was obtained when using 450W power, which was 0.190 grams. Based on the experimental data obtained, the most suitable kinetic model is second-order model. This can be analyzed from the highest R2 (0.9946 – 0.9999) and the lowest RMSE (0.0062 – 0.0349). Increasing the irradiation power will affect the extraction rate and parameter values of each kinetic model.
