Abstract

Indonesia has enormous biomass resources due to its land territory is mostly surrounded by forests and agricultural area. One of the main agricultural commodities is Gayo Arabica coffee. Coffee agro-residue such as coffee-pulp contains glucose, organic matter, protein, nitrogen and high minerals. Therefore, coffee pulp can be a potential raw material for bioethanol production. In order to develop an effective technology for bioethanol production from coffee-pulp, it is necessary to investigate in early the way of glucose can be effectively prepared. In this preliminary investigation, glucose products ware prepared using two methods, i.e. method-I under several main-stages including extraction, delignification, and hydrolysis. While, under method-II, the sample was directly hydrolyzed at 100°C for 4 h. Under both methods, hydrolysis process to get glucose was performed by adding sulfuric acid (H2SO4) at various concentrations (8 wt.%, 10 wt.% and 12 wt.%). Based on analysis results, the highest glucose level, i.e. 17 % was obtained from method-II by adding 8 wt.% sulfuric acid. The less the amount of sulfuric acid added, the higher the glucose level produced. No difference in pH was found from both methods. The color of glucose produced under method-I is clearer compared to those prepared under method-II.

Abstract

KM.6 Village is a village where most of its area functions as oil palm, rubber, and areca nut plantations. Citronella oil farmer community in Kec. Simpang Keuramat is the driving farmer who has initiated to grow fragrant lemongrass as one of the essential oil raw materials. The processing of fragrant lemongrass leaves into citronella oil significantly increases the economic value. In the field, things that affect the quality and quantity of citronella oil produced are found because farmers, as workers, are unskilled and inexperienced in the refining process and unscheduled harvesting and refining operations. To improve this situation, guidance was carried out as a form of community service from Malikussaleh University. The implementation of this service activity is by providing counseling and assistance in making harvest and distillation schedules. The scheduling guidance aims to produce more citronella oil. More citronella oil can be achieved by minimizing idle time, thereby increasing the effectiveness of farmers and workers, which leads to increased productivity of citronella oil refining. From the changes in harvest and production scheduling made, there was an increase in the yield of citronella oil refined by 6% for one month planning period. The main hope of this activity is to improve the welfare of local farming communities by cultivating and processing fragrant lemongrass plants so that they can earn a living and fulfill their proper needs. --- Desa KM.6 merupakan desa yang sebagian besar wilayahnya difungsikan sebagai perkebunan sawit, karet, dan pinang. Masyarakat petani minyak sereh wangi di Kec. Simpang Keuramat merupakan petani penggerak yang menginisiasi menanam tanaman sereh wangi sebagai salah satu bahan baku minyak atsiri. Proses pengolahan daun sereh wangi menjadi minyak sereh wangi meningkat nilai ekonomis secara signifikan. Namun, kualitas dan kuantitas minyak sereh wangi yang dihasilkan kurang baik karena petani tidak terampil dan tidak berpengalaman dalam proses penyulingan serta pelaksanaan panen dan penyulingan yang tidak terjadwal. Untuk memperbaiki situasi tersebut, maka dilaksanakan bimbingan penjadwalan panen dan produksi sebagai bentuk pengabdian masyarakat. Pelaksanaan kegiatan pengabdian ini dilakukan dengan memberikan penyuluhan dan pendampingan pembuatan jadwal panen dan penyulingan. Bimbingan penjadwalan yang dilakukan bertujuan menghasilkan minyak sereh wangi dengan kuantitas yang lebih banyak. Hasil yang lebih banyak dapat diraih dengan meminimalisir waktu kosong (idle time) sehingga meningkatkan efektivitas petani dan pekerja yang berujung pada peningkatan produktivitas penyulingan minyak sereh wangi. Dari perubahan penjadwalan panen dan produksi yang dilakukan, terjadi penambahan hasil penyulingan minyak sereh wangi sebanyak 6% untuk periode perencanaan satu bulan. Harapan utama dari kegiatan ini adalah meningkatkan kesejahteraan masyarakat petani lokal dengan budidaya dan pengolahan tanaman sereh wangi sehingga mendapatkan penghidupan serta pemenuhan kebutuhan yang layak.
