Abstract

Penggunaan maggot atau larva Black Solider Fly (BSF) sebagai pengurai limbah organik sudah banyak diaplikasikan di Indonesia. Hal ini dikarenakan kemampuannya dalam mengurai limbah organik mencapai 52-56%. Produk yang dihasilkan dari pengolahan BSF diantaranya larva, kasgot, dan residu. Tempat Budidaya Larva BSF Pasar Puspa Agro Sidoarjo menghasilkan kasgot mencapai 50-100 kg/hari. Permasalahan yang dimiliki adalah belum dilakukannya uji karakteristik kasgot, sehingga belum diketahui apakah kandungannya sesuai dengan baku mutu pupuk organik yang ditetapkan oleh Permentan No. 261/KPTS/SR. 310/M/4/2019. Selain itu, belum diketahui juga kemampuan kasgot yang dihasilkan sebagai campuran media tanam pada pertumbuhan tanaman pakcoy (Brassica rapa chinensis). Penelitian pendahuluan berjalan selama 30 hari, dengan menganalisis karakteristik kasgot yang dihasilkan menggunakan lima variasi substrat maggot, diantaranya SH1 (100% sampah resto hotel), SP1 (100% sampah pasar), RB1 (90% sampah resto hotel dan 10% sampah pasar), RB2 (80% sampah resto hotel dan 20% sampah pasar), serta RB3 (70% sampah resto hotel dan 30%) sampah pasar. Parameter uji karakteristik yang digunakan adalah kadar air, pH, C-organik, total N, rasio C/N, P, dan K. Kemudian dilanjutkan dengan penelitian pendahuluan selama 35 hari berupa penumbuhan tanaman pakcoy (Brassica rapa chinensis) menggunakan 2 jenis substrat maggot, yaitu RB1 sebagai kasgot dengan kualitas terbaik dan SH1 sebagai interpretasi produk kasgot Tempat Budidaya Larva BSF Pasar Puspa Agro Sidoarjo. Pada pertumbuhan tanaman pakcoy, kasgot digunakan sebagai campuran media tanam dengan variasi dosis 150 gram kasgot/500 gram media tanam, 200 gram kasgot/500 gram media tanam, dan 250 gram kasgot/500 gram media tanam. Dengan variasi dosis kasgot tersebut, dilakukan analisis pertumbuhan tanaman dengan parameter tinggi, jumlah daun dan, diameter batang semu tanaman, serta pemanenan tanaman dengan parameter berat basah tanaman. Hasil penelitian pendahuluan terkait uji karakteristik kasgot, menunjukkan bahwa seluruh jenis kasgot yang dihasilkan memenuhi baku mutu pupuk organik berdasarkan Permentan No. 261/KPTS/SR.310/M/4/2019. Hasil uji ANOVA One-Way dengan metode Duncan dan matriks penilaian karakteristik kasgot menunjukkan bahwa jenis substrat RB2 memiliki karakteristik kasgot terbaik dengan karakteristik kadar air (14,72%), pH (7,1), C-Organik (50,1%), N-total (8,34%), rasio C/N (6,01), fosfor (1,1%), dan kalium (3,86%). Hasil penelitian utama terkait pertumbuhan tanaman pakcoy menunjukkan bahwa pertumbuhan tanaman terbaik dimiliki oleh tanaman yang menggunakan campuran media tanam SH1 (100% sampah resto hotel) dengan dosis 150 gram kasgot/500 gram media tanam. Namun, pertumbuhan tanaman dengan dosis tersebut masih berada di bawah tanaman yang menggunakan media tanam secara penuh yaitu dosis 0 gram kasgot/500 gram media tanam.
=======================================================================================================================
The use of maggot or Black Soldier Fly (BSF) larvae as organic waste decomposers has been widely applied in Indonesia. This is due to their ability to decompose organic waste by up to 52–56%. The products resulting from BSF processing include larvae, kasgot (BSF frass), and residue. The BSF Larvae Cultivation Center at Puspa Agro Market in Sidoarjo produces kasgot at a rate of 50–100 kg per day. However, one of the main issues is that no characterization test of the kasgot has been conducted, so it is still unknown whether its composition complies with the organic fertilizer quality standards set by the Ministry of Agriculture Regulation No. 261/KPTS/SR.310/M/4/2019. Additionally, the effectiveness of the resulting kasgot as a growing media mixture for the cultivation of pakcoy (Brassica rapa chinensis) is also yet to be determined.
The preliminary study was conducted over 30 days by analyzing the characteristics of the kasgot produced using five types of maggot substrates: SH1 (100% restaurant and hotel waste), SP1 (100% market waste), RB1 (90% restaurant and hotel waste and 10% market waste), RB2 (80% restaurant and hotel waste and 20% market waste), and RB3 (70% restaurant and hotel waste and 30% market waste). The parameters used for kasgot characterization included moisture content, pH, organic carbon (C-organic), total nitrogen (N-total), C/N ratio, phosphorus (P), and potassium (K). This was followed by a 35-day preliminary study involving the cultivation of pakcoy (Brassica rapa chinensis) using two types of maggot substrates: RB1 as the best-quality kasgot, and SH1 as a representation of the kasgot product from the BSF Larvae Cultivation Center at Puspa Agro Market, Sidoarjo. In the plant growth experiment, kasgot was used as a growing media mixture with dosage variations of 150 grams kasgot/500 grams growing media, 200 grams kasgot/500 grams growing media, and 250 grams kasgot/500 grams growing media. Plant growth was analyzed using parameters such as plant height, number of leaves, and pseudostem diameter, while harvesting was evaluated based on the fresh weight of the plant.
The preliminary study on kasgot characterization showed that all types of kasgot produced met the organic fertilizer quality standards based on the Ministry of Agriculture Regulation No. 261/KPTS/SR.310/M/4/2019. The results of the One-Way ANOVA test using the Duncan method and the kasgot characteristic scoring matrix indicated that the RB2 substrate produced the best kasgot, with the following characteristics: moisture content (14.72%), pH (7.1), organic carbon (50.1%), total nitrogen (8.34%), C/N ratio (6.01), phosphorus (1.1%), and potassium (3.86%). The main research on pakcoy plant growth showed that the best growth was observed in plants using the SH1 substrate (100% restaurant and hotel waste) with a kasgot dosage of 150 grams per 500 grams of growing media. However, the growth of these plants was still lower compared to those grown entirely with standard growing media (0 grams kasgot/500 grams media).
