Coffee plantation within community forest (HKm) requires the use of an agroforestry system, but knowledge of the concept and its implementation in the field, is still lacking. The use of shade trees in coffee plantations is known to be beneficial for the long-term sustainability of coffee production. Recent result of coffee harvests are still low due to minimal intensification methods and maintenance e.g. in returning of soil nutrients into the agroforestry system. This community service program is carried out to, first, provide an understanding of the importance of shade trees within coffee plantations in the Agroforestry system, second, restore and increase soil nutrients by making compost from coffee husks. And third, introduce red-picking fruit harvest to increase the value of the community's coffee bean. The results of the activity showed better understanding in the arrangement of shade trees and increased skills in composting from coffee husks. The increase in crop yields is still in the implementation stage by using self-made compost which is sown on coffee plantations. The sustainability of this program can be achieved by involving young people in forest farmer groups and the coffee composting business can provide income, in addition to being used alone in their coffee plantation. With the addition of coffee husk compost, it is believed that it will increase coffee yields in the future and with changes in the red-picking harvest pattern, the price of coffee bean will be higher. Abstrak Penanaman kopi rakyat di areal Hutan kemasyarakatan (HKm) mensyaratkan penggunaan sistem Agroforestry, namun pengetahuan tentang konsep dan implementasi Agroforestry di lapangan masih sangat minim. Penggunaan pohon naungan dalam kebun kopi telah diketahui manfaatnya untuk keberlanjutan produksi kopi dalam jangka panjang. Hasil panen kopi yang dihasilkan masih rendah sengan minimnya intensifikasi perawatan dan pengembalian hara tanah ke dalam system Agroferestry. Program pengabdian ini dilaksanakan untuk 1. Memberikan pemahaman tentang pentingnya pohon naungan dalam kebun kopi rakyat system Agroforestry, 2. Mengembalikan dan meningkatkan unsur hara tanah dengan pembuatan kompos dari kulit kopi. 3. Memberikan wawasan pola panen petik merah untuk peningkatan nilai panen kopi masyarakat. Hasil kegiatan menunjukkan pemahanman yang lebih baik dalam hal pengaturan pohon naungan dan meningkatnya ketrampilan dalam pembuatan kompos dari kulit kopi. Peningkatan hasil panen masih dalam tahap implementasi/pemakaiana kompos hasil pembuatan sendiri yang ditabur di lahan kebun kopi. Keberlanjutan program ini dapat dicapai dengan pelibatan kaum muda di kelompok tani hutan dan usaha pembuatan kompos kopi dapat memberikan pendapatan, selain dipakai sendiri di kebun kopinya. Dengan penambahan kompos kulit kopi dipercaya akan meningkatkan hasil panen kopi di masa yang akan datang dan dengan adanya perubahan pola panen petik merah membuat harga kopi yang dihasilkan akan lebih tinggi.

Status: PreprintStrategy formulation was conducted to develop organic agriculture as sustainable agricultural practice in Bengkulu Province. This research used multicriteria decision-making tools which were analytical hierarchy process (AHP) and strength-weakness-opportunity-threat (SWOT) analysis to generate alternative strategies. Then, fuzzy analytical hierarchy process (fuzzy-AHP) was utilized to choose the best strategy for developing organic agriculture in Bengkulu Province. The results identified five strength factors, 16 weakness factors, eight opportunity factors and seven threat factors. The evaluation of internal and external factors led to the internal factor value of 2.26 and the external factor value of 2.54. This result placed the current condition of organic agriculture development in Bengkulu Province in the position of weakness-opportunity (WO) quadrant. The fuzzy-AHP analysis ranked the strategies, respectively developing export-oriented competitive organic products, supporting the production and marketing of organic products, and developing community supported organic agriculture

Artisanal and small scale gold mining (ASGM) is considered as the largest source of mercury pollution worldwide. The ASGM has been practiced for years in the area of Lebong Regency of Bengkulu Province. To extract gold from the ores, miners use a simple technique called Gelondong. This practice involves amalgamation process which forms amalgam, a mixure composed of mercury and gold. These amalgamation generates liquid and solid wastes (tailings) which still contain significant amount of mercury. Consequently, ASGM activities can potentially create mercury contamination of the environment, especially aquatic ecosystems. This study was aimed to investigate the concentration and distribution of total mercury in rivers to which wastes from ASGM communities in three villages of North Lebong District were dumped. Water and streambed sediments along the rivers were collected and brought to the laboratory for total mercury analysis. Data showed that total mercury was not detected in the river water but high in the river sediments with high variations among lactions from 0.11 to 110.37 mg kg-1. Apparently, total mercury tended to decrease with the distance from it source. High amounts of mercury in the river sediments could potentially spread to wider area and cause bioaccumulation in aquatic organisms, especially fish which can be dangerous to consume.
