Abstract

This study aimed to determine physical properties (temperature) and chemical characteristics (pH) at days 0, 14, and 28, as well as Nitrogen (N), Phosphorus (P), and Potassium (K) levels at days 14 and 28, in compost made from mangrove litter. The study employed three material ratio treatments: A1B1 (500 g mangrove litter : 500 g kepok banana peel), A1B2 (700 g : 300 g), and A1B3 (300 g : 700 g). The composting process was conducted anaerobically over the 28-day period with the addition of EM4, sugar, and water. The results indicated that the best performance—regarding temperature, pH, and N, P, and K levels—was achieved by the compost using a ratio of 300 g mangrove litter to 700 g banana peel. This treatment yielded a temperature of 30–35°C, pH of 5–7, N of 1.92–2.23%, P of 0.21–0.38%, and K of 2.14–2.23%. These values ​​met the established SNI 19-7030-2004 standards (temperature 28–30°C, pH 6.80–7.49, minimum N 0.40%, minimum P 0.10%, and minimum K 0.20%).

Abstract

Penelitian ini bertujuan untuk mengetahui respon pertumbuhan bibit tanaman karet terhadap pemberian biofertilizer berbasis MOL kulit pisang kepok dan pupuk kandang sapi, menentukan dosis terbaik, serta mengetahui adanya interaksi antara kedua perlakuan tersebut. Penelitian dilaksanakan menggunakan Rancangan Acak Lengkap (RAL)  faktorial dua faktor, yaitu biofertilizer berbasis MOL kulit pisang (0, 75, dan 150ml/0,5 liter air) dan pupuk kandang sapi (0, 200, dan 300 g/polybag). Hasil penelitian menunjukkan bahwa pemberian biofertilizer berbasis  mikroorganisme lokal kulit pisang kepok dan pupuk kandang sapi berpengaruh  nyata terhadap seluruh parameter pengamatan. Dosis biofertilizer berbasis MOL kulit pisang kepok 150 ml/0,5 liter air dan pupuk kandang sapi 300 g/polybag memberikan hasil terbaik terhadap pertumbuhan bibit karet. Interaksi kedua  perlakuan berpengaruh nyata terhadap tinggi tanaman, diameter batang, jumlah  payung, dan panjang akar. Penelitian ini menunjukkan bahwa pemberian biofertilizer berbasis mikroorganisme lokal kulit pisang kepok 150 ml/0,5 liter air  dan pupuk kandang sapi 300 g/polybag efektif meningkatkan pertumbuhan bibit karet.
