Abstract

Decomposer insect diversity are decomposer insect in Oil Plants in different growth phases at PT. Mopoli Raya Rantau Aceh Tamiang. This study aims to determine the high number of decomposer insect diversity in immature oil palm plantations and mature plantations at PT. Mopoli Raya. The research was carried out by the Oil Palm Plantation of PT. Mopoli Raya, Laboratory of Plant Pests and Diseases, Faculty of Agriculture Almuslim University Matangglumpangdua and Entomology Laboratory of Agriculture Gadjah Mada University Yogyakarta. The research took place from January to June 2022. The experiment used a survey method, focused on the diversity of decomposer insects. Insect sampling was carried out using a purposive sampling method, by selecting two stretches of oil palm plantations managed by the company. The observed variables were family composition and abundance of individual decomposers, composition and structure of decomposer species. The results showed that the species richness of immature oil palm was lower than that of mature plantations. This was suspected to be more intensive in immature oil palm, which resulted in a negative impact on the presence of decomposers compared to mature oil palm. The diversity of natural enemies of decomposers in producing oil palm plantations was higher, namely 67 individuals compared to immature oil palm plantations, namely 34 individuals. The benefit of research for the development of science is as a basis for pest control in company-owned and community plantations by using natural enemies found at PT. Mopoli Raya.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh biopestisida daun sembukan dan tembakau kering terhadap ulat penggulung daun pada tanaman padi, yang dilaksanakan di lahan Desa Cot Puuk, Kecamatan Gandapura, Kabupaten Bireuen, pada bulan Januari sampai bulan Maret 2024, dengan ketinggian tempat 197 mdpl. Penelitian ini menggunakan rancangan acak kelompok (RAK) non faktorial yaitu pengaruh Biopestisida (B), terdiri dari 7 taraf : B0 : Tanpa Pemberian Biopestisida (Kontrol), B1: 20 ml/L Air, B2 : 30 ml/L Air, B3: 40 ml/L Air, B4 : 50 ml/L Air, B5 : 60 ml/L Air dan B6 : 70 ml/L Air. Parameter yang diamati dalam penelitian ini meliputi tingkat mortalitas, kecepatan waktu kematian, intensitas serangan, tinggi tanaman, dan jumlah daun. Hasil penelitian menunjukkan bahwa perlakuan Biopestisida daun sembukan dan tembakau kering berpengaruh berpengaruh sangat nyata terhadap tingkat mortalitas yaitu 100.00%, kecepatan waktu kematian yaitu 1,00 hari dan intensitas serangan 0,00%. Perlakuan terbaik dijumpai pada perlakuan Biopestisida dengan konsentrasi 70 ml /1iter Air, akan tetapi perlakuan Biopestisida daun sembukan dan tembakau kering berpengaruh tidak nyata terhadap tinggi tanaman dan jumlah anakan pada umur 15 dan 30 HST.
