Abstract
Metode pengelolaan sampah di Indonesia masih dititik beratkan pada metode penimbunan sampah di TPA. Sampah di Indonesia didominasi oleh sampah organik. Sampah organik di Kota Surabaya menduduki tingkat pertama dengan persentase 71,96%. Pengelolaan sampah memanfaatkan larva Black Soldier Fly (BSF) dari spesies Hermetia illucens mampu mereduksi sampah organik sebesar 50-85%. Selain itu, larva BSF dapat dipanen dan dijadikan pakan ternak karena mampu mengonversi sampah menjadi kandungan nutrisi dalam tubuhnya. Penelitian ini memiliki tiga tujuan yaitu tujuan pertama untuk menentukan rasio komposisi sampah dengan variasi jenis sampah yang dapat memberikan persentase reduksi terbesar. Tujuan kedua adalah menentukan tingkat pengaruh pertumbuhan larva dari variasi rasio terpilih. Tujuan ketiga menentukan karakteristik fisik-kimia hasil dekomposisi sampah organik oleh larva BSF. Penelitian ini dilakukan dalam skala laboratorium, dengan menggunakan larva BSF berusia enam hari. Pada penelitian ini terdapat dua jenis variabel penelitian yaitu variabel jenis sampah yang digunakan dan variabel rasio komposisi campuran sampah. Jenis sampah campuran yang digunakan adalah sampah sisa makanan yang dicampurkan dengan masing-masing residu kompos windrow, kompos windrow setengah matang, dan kotoran sapi. Rasio komposisi sampah yang digunakan adalah 90:10, 70:30, dan 60:40. Hasil penelitian didapatkan persentase reduksi sampah organik terbesar oleh larva BSF adalah pada rasio 90:10 disetiap komposisi sampah campuran. Reduksi sampah pada campuran sisa makanan dan windrow setengah matang (SM:WS) 90:10 sebesar 82,18%. Reduksi sampah pada campuran sisa makanan dan residu kompos windrow (SM:RW) 90:10 sebesar 79%. Reduksi sampah pada campuran sisa makanan dan kotoran sapi (SM:KS) 90:10 sebesar 74,5%. Kandungan protein yang terkonversi pada jenis SM:WS (90:10) adalah 54,6%, SM:RW (90:10) adalah 63,11% dan pada SM:KS (90:10) 48,75%.

The solid waste management method in Indonesia was still focused on the landfilling method. Solid waste composition in Indonesia was dominated by organic waste. Organic solid waste in Surabaya City occupies the first level, that reaching up to 71,96%. The alternative management of organic waste will be able to reduce the waste load which is enter the landfill. Waste management using Black Soldier Fly (BSF) larvae from the Hermetia illucens species capable of reducing organic waste by 50-85%. Besides, BSF larvae can be harvested and used as animal feed because they can convert waste into nutrients in the body. This study has three objectives, the first objective is to determine the composition ratio of waste with variations in the type of waste that can provide the largest reduction percentage. The second objective is to determine the level of larval growth from each selected variation ratio. The third objective is to determine the physical-chemical characteristics of the decomposition of organic waste carried out by BSF larvae. This research was carried out on a laboratory scale, using BSF larvae aged six days. The types of waste that used was mixtures of fresh food waste with other organic waste types, i.e., immature windrow composting material, windrow compost residue, and fresh cow manure at three different composition ratios. The composition ratio of food waste with the other wastes used was 90:10, 70:30, and 60:40. The results showed that the highest reduction was at the ratio of 90:10 achieved for each component of mixtures waste. Waste reduction in mixtures of food waste and immature windrow composting material (SM:WS) 90:10 was 82,18%. Waste reduction in mixtures of food waste and windrow compost residue (SM:RW) 90:10 was 79%. Waste reduction in mixtures of food waste and cow manure (SM:KS) 90:10 was 74,5%. The converted protein content in type SM:WS (90:10) was 54,6%, SM:RW (90:10) was 63,11% and in SM:KS (90:10) was 48,75%.
