ABSTRAK Pengelolaan limbah organik sisa pertanian maupun limbah rumah tangga menjadi hal yang perlu diperhatikan, karena akan berdampak negatif bagi lingkungan. Desa Rawa Selapan merupakan salah satu desa dengan luas sawah terbesar di Lampung Selatan. Selama ini, limbah pertanian di desa tidak dimanfaatkan dengan baik. Selain itu, sistem pertanian dengan penggunaan pupuk kimia dapat mengubah ketersediaan hara dan mikroorganisme tanah sehingga tanah mengalami penurunan tingkat kesuburan. Salah satu upaya untuk memanfaatkan limbah organik dan meningkatkan kesuburan tanah yaitu mengolah limbah organik menjadi pupuk organik/kompos. Kegiatan ini bertujuan untuk memanfaatkan limbah organik pertanian di Desa Rawa Selapan, serta melatih masyarakat desa membuat pupuk kompos menggunakan alat fermentor dan rotary biocomposter. Kegiatan dilakukan dengan tahapan persiapan, pembuatan alat fermentor dan rotary biocomposter, pelaksanaan kegiatan dengan pemaparan materi dan pelatihan pembuatan kompos, serta hasil kegiatan dievaluasi dengan kuisioner. Terdapat peningkatan pemahaman peserta mengenai pembuatan pupuk menggunakan fermentor dan rotary biocomposter, yang semula hanya 39% menjadi 83% peserta yang memahami hal ini. Selain itu, berdasarkan post-test, sebanyak 91% peserta menjawab akan melanjutkan pembuatan pupuk organik menggunakan fermentor dan biocomposter. Kegiatan ini berhasil meningkatkan pengetahuan peserta mengenai dampak negatif penumpukan limbah organik dan penggunaan pupuk kimia berkepanjangan. Selain itu, peserta kegiatan juga telah menguasai teknik pembuatan pupuk kompos dan bioaktivator berbasis fermentasi menggunakan alat fermentor dan rotary biocomposter.

Rawa Selapan Village is one of the villages with the largest rice field area in South Lampung. So far, agricultural waste in the village has not been utilized properly. In addition, agricultural systems using chemical fertilizers can alter the availability of soil nutrients and microorganisms, resulting in decreased soil fertility. One approach to utilizing organic waste and increasing soil fertility is the conversion of organic waste into organic fertilizer/compost. Objective: This activity aims to utilize organic agricultural waste in Rawa Selapan Village and provide training to village communities on compost production using fermenters and rotary biocomposters. This activity aims to utilize organic agricultural waste in Rawa Selapan Village, as well as train village communities to make compost using fermenters and rotary biocomposters. The activity was carried out in several stages, including preparation stages, building a fermenter and rotary biocomposter, explanation of materials, training in compost production, and the evaluation of the program using a questionnaire. Participants' understanding of compost production using fermenters and rotary biocomposters increased from an initial 39% to 83%. Furthermore, 91% of participants indicated their intention to continue producing organic fertilizer using fermenters and biocomposters based on the post-test result. This activity succeeded in increasing participants' knowledge regarding the negative impacts of organic waste accumulation and prolonged use of chemical fertilizers. Additionally, activity participants have acquired proficiency in fermentation-based compost fertilizer production and the use of bioactivators with fermenters and rotary biocomposters.
