Abstract

Besarnya hasil produksi kopi di Desa Sriwulan diiringi dengan besarnya limbah tanaman kopi. Selain itu, Kualitas rendah tanaman kopi yang dihasilkan turut mempengaruhi produktivitas dan perekonomian petani karna kurangnya pengetahuan terhadap budidaya tanaman kopi. Oleh karena itu, tujuan dilakukannya pengabdian di Desa Sriwulan ini adalah untuk memanfaatkan limbah daun kopi menjadi teh kombucha dan dampak penanaman tumbuhan penaung lamtoro pada kualitas mutu kopi serta strategi pemasaran digital guna meningkatkan ekonomi di Desa Sriwulan. Metode yang digunakan dalam penelitian ini adalah literatur review. Pelaksanaan pengabdian ini dibagi menjadi tiga kegiatan yaitu sosialisasi pembuatan teh kombucha, penanaman tumbuhan penaung, dan pemberian materi sosialisasi digital marketing dan pembuatan akun OSS. Hasil penelitian menunjukkan bahwa pengolahan limbah daun kopi menjadi teh kombucha memiliki potensi sebagai solusi berkelanjutan dalam pengelolaan limbah dan peningkatan pendapatan lokal. Selain itu, penanaman tumbuhan penaung lamtoro memberikan dampak pada peningkatan kualitas kopi yang dihasilkan. Kesimpulannya, pengabdian ini menciptakan potensi keberlanjutan dalam pengolahan limbah, pertanian dan ekonomi di Desa Sriwulan, memberikan bukti nyata tentang bagaimana praktik inovatif dapat merangkul aspek ekonomi dan lingkungan secara seimbang.

Abstract

Biodiesel is a solution to the problem of depleting fossil fuel sources in Indonesia. Biodiesel can be derived from vegetable and animal fats. On the other hand, microalgae cultivation areas are spread across 26 provinces in Indonesia with a production potential of 462,400 tonnes/year. Microalgae with lipid content ranging from 38% - 60% can be converted into crude biodiesel as much as 35%. Irradiation microwave is the simplest and most effective technology with a constructive method for extracting oil from animal and vegetable fats, and biomass, and can be scaled easily. Using irradiation microwave, oil will be extracted from microalgae using hexane: methanol solvent for 60 minutes with a microwave power of 600 watts. Microalgae extraction with the help of irradiation microwave can produce more lipids compared to conventional lipid extraction which is 31% and 26% higher. Microalgae that go through a treatment process using irradiation microwave is more efficient because the average cost is two-thirds less compared to conventional heating, its lower energy consumption, lower costs, a more effective heating process, can increase production, and have a big impact on increasing biofuel yields.
