Abstract

Air limbah industri susu bersumber dari beberapa proses pengolahan, seperti pelarutan, penyucian alat dan mesin, air residu proses pengolahan susu, luapan pada tangki, dan juga susu reject. Susu reject merupakan hasil produk susu yang tidak dapat didistribusikan karena tidak memenuhi standar kualitas produk yang layak untuk didistribusikan. Air limbah industri susu berupa susu reject memiliki kandungan yang kaya akan zat organik, seperti protein dan lemak, sehingga susu reject berpotensi dimanfaatkan sebagai pakan larva BSF.
Pada penelitian ini dilakukan pemanfaatan susu reject dengan menggunakan larva Black Soldier Fly (BSF). Selain susu reject, digunakan limbah ampas tahu sebagai variasi bahan pakan larva BSF. Penelitian dilakukan dengan pemberian pakan larva BSF menggunakan lima variasi komposisi pakan; 100% susu reject, 75% susu reject dan 25% ampas tahu, 50% susu reject dan 50% ampas tahu, 25% susu reject dan 75% ampas tahu, 100% ampas tahu. Masing- masing variasi pakan diberikan pada larva BSF setiap tiga hari sekali, sejumlah 1 kg. Setiap tiga hari sekali dilakukan pengamatan yang meliputi suhu, pH, ukuran dan berat larva BSF. Larva BSF dipanen dan ditimbang untuk dibandingkan hasilnya dari setiap variasi komposisi.
Susu reject mengandung 84,48% kadar air, 5,92% protein, dan 24,38% lemak. Ampas tahu memiliki kandungan 87,84% kadar air, 3,31% protein dan 17,05% lemak. Hasil panen larva memiliki hasil rata-rata tertinggi pada larva BSF dengan media pakan 50% susu reject dan 50% ampas tahu, yaitu 226,5 gr larva, dan hasil rata-rata terendah pada media pakan 100% susu yaitu 90 gr. Berdasarkan hasil tersebut, diketahui bahwa media pakan yang optimum yaitu media pakan dengan komposisi 50% susu reject dan 50% ampas tahu.

Milk industry wastewater includes waters from some of processing, i.e. dissolving, cleaning tools and machines, residual water from milk processing, overflow in tanks, and rejected products. Rejected products are the milk products which unable to distributed due to the product quality standards. This results occurs due to various factors, includes errors in the production process, bad raw materials, or human error. Dairy industry wasterwater in the form of rejected milk contains high organic matter, such as protein and fat. Rejected milk has the potential ti be used as BSF larvae feed.
In this research studied about the processing of rejected milk using Black Soldier Fly (BSF) larvae. In addition, tofu waste will be used as the subsidiary of the feed. The mixed feed consist of five variations; 1) 100% rejected milk, 2) mix of 75% rejected milk and 25% tofu waste, 3) mix of 50% rejected milk and 50% tofu waste, 4) mix of 25% rejected milk and 75% tofu waste, 5) 100% tofu waste. Feeding frequency once every three days, with one kilogram each feed.
Rejected milk contains of 84,48% water, 24,38% fat, and 5,92% protein. Tofu waste contains 87,84% water, 17,05% fat, and 3,31% protein. Feed with mixture of 50% rejected milk and 50% tofu waste produce the most results with 226,5 grams of pupas and the fewest results with 90 grams of pupas is fed with 100% rejected milk. Based on the results, mixture of 50% rejected milk and 50% tofu waste is the optimum feed ratio for BSF larvae between the others.
