Abstract

Waste is a global problem, both developed and developing countries. It is estimated that in 2025 the population will increase by 284.83 million people with an estimated increase in the amount of waste to 5.93 million tons per year. The accumulation of garbage produces toxic liquids (leachate) that can degrade the quality of rivers, groundwater, and soil. This study aimed to analyze the ability of Hermetia illucens larvae to consume bait and the reduction index on 15g of organic waste in the form of 5g cabbage, 5g rice and 5g fish offal with variations of 0 larvae, 15 larvae, 20 larvae and 25 larvae for 15 days. This research is an experimental research with Posttest-only Control Design. Based on the results of the study, it can be seen that the control group has the characteristics of sharp-scented waste, it is contaminated with house fly larvae. The treatment group had the opposite characteristics, namely that the waste had no sharp odor, was not contaminated with other fly larvae other than Hermetia Illucens larvae and there was no larval death in all samples. The highest feed consumption was in the P3 group with a feed consumption value of 92.22% and the lowest was in the P0 group, which was 71.11%. The highest decomposition index was in the P3 group of 6.15% and the lowest was in the P0 group, which was 4.74%.

Abstract

Kromium (Cr) merupakan logam berat dengan sifat persisten, bioakumulatif dan toksik (PBT) yang banyak ditemukan dalam limbah cair batik akibat penggunaan bahan kimia. Penelitian ini dilakukan pada limbah cair Industri Batik Tulis X di Kaliwates, Jember dengan kadar Cr mencapai 1,820 mg/L, melebihi baku mutu lingkungan. Penelitian bertujuan untuk mengevaluasi potensi arang aktif dari batang tembakau dalam menurunkan kadar Cr. Metode yang digunakan adalah True Experiment, dimana arang aktif yang dihasilkan melalui karbonisasi dan aktivasi H2SO4 digunakan untuk perlakuan berupa penambahan massa arang aktif pada limbah cair batik. Rata- rata kadar Cr masing-masing pada setiap kelompok perlakuan yaitu X1 sebesar 1,139 mg/L, X2 sebesar 1,082 mg/L dan X3 sebesar 0,278 mg/L. Hasil pengujian menunjukkan penurunan kadar Cr yang signifikan, dengan kelompok perlakuan X3 menurunkan kadar Cr hingga 75,84%. Disarankan kepada pemilik industri batik untuk mengolah limbah, memantau kadar Cr secara berkala, serta melakukan substitusi dengan pewarna ramah lingkungan dan pengelolaan arang aktif bekas.
