Abstract

Kelengkeng (Dimocarpus longan L.) merupakan komoditas hortikultura penting dengan prospek agribisnis yang tinggi. Keberadaan serangga pada ekosistem kebun kelengkeng dapat memberikan dampak positif maupun negatif, baik sebagai penyerbuk, predator, maupun hama yang merugikan. Penelitian ini bertujuan untuk mengidentifikasi keanekaragaman dan peran ekologis serangga pada perkebunan kelengkeng di Bawen serta menganalisis faktor lingkungan yang memengaruhinya. Penelitian dilakukan dengan metode hand collecting dan pitfall trap. Identifikasi serangga dilakukan secara morfologis dengan bantuan perangkat lunak dan pengukuran faktor lingkungan diukur menggunakan termohigrometer dan lux meter. Data dianalisis menggunakan indeks keanekaragaman Shannon-Wiener (H’), kemerataan (E), dan dominansi Simpson (C). Hasil penelitian menunjukkan sebanyak 1.277 individu serangga dari berbagai ordo dengan peran beragam meliputi predator, polinator, herbivora, pengisap cairan tanaman, penggerek, dan detritivor. Nilai indeks keanekaragaman H’ sebesar 1,9611 (kategori sedang), indeks kemerataan E = 0,5214 (sedang), dan dominansi C = 0,2652 (rendah). Faktor lingkungan berupa suhu 25–30℃, kelembaban 66–84%, dan intensitas cahaya 1.017–8.424 lux berada pada kisaran optimum bagi kehidupan serangga. Penelitian ini memberikan informasi dasar mengenai komposisi dan fungsi serangga pada kebun kelengkeng yang dapat digunakan sebagai dasar dalam pengendalian hama terpadu (PHT) serta mendukung keberlanjutan budidaya hortikultura.

Abstract

Household organic waste in urban settlements remains a persistent environmental challenge due to limited community-based processing systems and low levels of waste valorization. Many waste management initiatives are still activity-oriented and lack an integrated participatory circular framework that connects environmental, economic, and social dimensions. This community engagement program aimed to develop a Participatory Circular Community Model through the conversion of household organic waste into biofertilizer and Black Soldier Fly (Hermetia illucens) feed production in Plamongansari, Semarang, Indonesia. The program applied a collaborative approach involving youth organizations and women’s community groups through structured training, hands-on practice, production mentoring, and evaluation using pre- and post-assessment instruments. Organic household waste was processed into liquid and solid biofertilizer, while carbohydrate-rich residues were utilized as substrate for Black Soldier Fly larvae cultivation. The results demonstrate significant improvements in community knowledge, technical skills, and environmental awareness, accompanied by the production of economically valuable organic fertilizer and maggot feed. The developed model illustrates how participatory circular practices can reduce household waste volume while generating micro-economic opportunities. This model offers a structured framework for sustainable urban waste management and presents strong replication potential for other urban communities seeking environmentally and economically viable waste solutions.
