Abstract

Palm oil mill effluent (POME) as one of the largest wastes produced in the crude palm oil (CPO) production process is one of the significant environmental challenges in the palm oil industry. POME contains low pH and also contains organic and highly nutritious materials so that it has the potential to be utilized. The land application method has been proposed as one solution to utilize POME sustainably. This study evaluated the utilization of POME through the land application method at PT. X, with a focus on the palm oil mill liquid waste management system and its effect on surface water quality. The data obtained showed that the PT.X palm oil mill liquid waste management system already succeeded in reducing BOD levels by 64.83%. The results of surface water quality tests in the upstream and downstream water bodies around the activity location also showed that most parameters were still below the quality standards required by the government regulations. However, supervision of the implementation of land application must always be carried out because it also has a risk of water pollution if not managed properly.

Abstract

Penelitian ini bertujuan untuk mengetahui densitas serangga predator dan polinator pada komposisi dan struktur vegetasi mangrove yang berbeda di kawasan ekosistem mangrove Desa Marga Sungsang dan Desa Sungsang IV, Kabupaten Banyuasin, Sumatera Selatan. Metode yang digunakan adalah deskriptif kuantitatif dengan teknik survei in-situ melalui observasi langsung terhadap vegetasi mangrove serta pengambilan sampel serangga menggunakan tiga teknik yaitu hand collecting, chemical knockdown, dan yellow trap. Titik sampling ditentukan secara purposive sampling dengan plot berukuran 10 x 10 m² pada transek 100 x 50 m² di setiap lokasi. Hasil penelitian menunjukkan bahwa serangga predator lebih dominan dan bervariasi dibandingkan serangga polinator. Terdapat hubungan timbal balik antara vegetasi mangrove dan serangga, di mana mangrove menyediakan habitat dan sumber makanan, sementara serangga membantu proses penyerbukan dan predasi. Struktur dan komposisi vegetasi berpengaruh signifikan terhadap kerapatan serangga, di mana vegetasi yang lebih kompleks mendukung keanekaragaman dan kepadatan serangga yang lebih tinggi.
