Abstract

Flamboyan is a market located in Pontianak City which produces organic waste with a percentage of 89.57%. The high level of organic waste produced at the Flamboyan Market can cause organic waste to decompose and cause unpleasant odors and become a vector of disease so that sanitation and environmental aesthetics decline. Therefore, it is necessary to handle the waste by composting. The purpose of this study was to determine the physical quality and chemical quality of compost based on color, odor, texture, temperature, pH, humidity, C/N ratio, nitrogen content (N), phosphorus content (P), and potassium content (K) against PERMENTAN No. 70 of 2011 and identified the effect of local microorganism activator of vegetable waste, EM4 and cow dung on the quality of compost maturity. This research method is aerobic composting with vegetable waste as the basic ingredients and the addition of local microorganism activator of vegetable waste, EM4 activator and cow dung activator with composting time of 35 days and using the same number of microorganisms, which is 7,850,000 cells. The results obtained, composting using the same number of microorganisms as many as 7,850,000 cells gave the best compost results in cow dung activator which is an effective activator in making compost in this study with parameters that have met quality standards consisting of a temperature of 31oC, pH of 5.8, blackish brown color, smell like soil, fine texture, potassium (K) content of 4.4%, C-Organic content of 32.9% and compost C/N ratio of 23.54 and MOL activator, EM4 and cow dung did not have a different effect on compost maturity. Keywords: Activator, Compost, EM4, Cow Dung, Local Microorganisms, Vegetable WasteA B S T R A K Flamboyan merupakan pasar yang terletak di Kota Pontianak yang menghasilkan sampah organik dengan persentase 89,57%. Tingginya kadar sampah organik yang dihasilkan di Pasar Flamboyan dapat menyebabkan sampah organik terurai dan menimbulkan bau tidak sedap serta menjadi vektor penyakit sehingga sanitasi dan estetika lingkungan menurun. Oleh karena itu, perlu dilakukan penanganan sampah dengan cara pengomposan. Tujuan penelitian ini adalah untuk mengetahui mutu fisik dan mutu kimia kompos berdasarkan warna, bau, tekstur, suhu, pH, kelembaban, rasio C/N, kandungan nitrogen (N), kandungan fosfor (P), dan kandungan kalium. (K) terhadap PERMENTAN No. 70 Tahun 2011 dan mengidentifikasi pengaruh aktivator mikroorganisme lokal limbah sayuran, EM4 dan kotoran sapi terhadap kualitas kematangan kompos. Metode penelitian ini adalah pengomposan aerobik dengan bahan dasar limbah sayuran dan penambahan aktivator mikroorganisme lokal limbah sayuran, aktivator EM4 dan aktivator kotoran sapi dengan waktu pengomposan 35 hari dan menggunakan jumlah mikroorganisme yang sama yaitu 7.850.000 sel. Hasil yang didapatkan, pengomposan dengan menggunakan jumlah mikroorganisme yang sama sebanyak 7.850.000 sel memberikan hasil kompos terbaik pada aktivator kotoran sapi yang merupakan aktivator yang efektif dalam pembuatan kompos pada penelitian ini dengan parameter yang telah memenuhi baku mutu yang terdiri dari suhu 31oC, pH 5,8, warna coklat kehitaman, berbau seperti tanah, tekstur halus, kandungan Kalium (K) 4,4%, kandungan C-Organik 32,9% dan rasio C/N kompos 23,54 dan aktivator MOL, EM4 dan kotoran sapi tidak memiliki efek yang berbeda pada kematangan kompos.

Abstract

The rapid economic and population growth of Pontianak City has triggered an increase in domestic waste. The composition of Pontianak City waste in 2020 is dominated by organic waste (91.8%). The wood processing industry will produce 50% of its waste, as sawdust. One of the efforts to reduce the generation of organic waste and sawdust is to use it as fuel in the form of environmentally friendly bio-briquettes. This paper studies the chemical characteristics of calorific value, moisture content, and ash content as they variations in the composition of the resulting bio-briquettes. The research methods include drying, curing, sieving at 40 mesh, mixing charcoal with 15% starch adhesive, and compaction. The composition variations in this study were sawdust (SG): organic waste (SO) (85%:15%, 75%:25%, and 65%:35%). The results showed that the highest calorific value was found in the composition variation of sawdust (SG) at 85%:15% organic waste (SO) of 49 cal/gr, while the highest water content was 20.52% and the highest ash content was 14.57% in the variation of the composition of sawdust (SG) 65%:35% organic waste (SO). The results of the chemical characteristics of calorific value, moisture content, and ash content of bio-briquettes did not meet the requirements of SNI 01-6235-2000. Keywords: bio-briquettes, alternative energy, organic waste, sawdust  ABSTRAK Pesatnya pertumbuhan ekonomi dan penduduk Kota Pontianak memicu peningkatan sampah domestik. Komposisi sampah Kota Pontianak tahun 2020 didominasi oleh sampah organik (91,8%). Industri pengolahan kayu akan menghasilkan 50% limbahnya berupa serbuk gergaji. Salah satu upaya untuk mengurangi timbulan sampah organik dan serbuk gergaji adalah dengan memanfaatkannya sebagai bahan bakar berupa biobriket ramah lingkungan. Makalah ini mempelajari karakteristik kimia nilai kalor, kadar air, dan kadar abu sebagai variasi komposisi biobriket yang dihasilkan. Metode penelitian meliputi pengeringan, pemeraman, pengayakan pada ukuran 40 mesh, pencampuran arang dengan perekat kanji 15%, dan pemadatan. Variasi komposisi pada penelitian ini adalah serbuk gergaji (SG): sampah organik (SO) (85% : 15%, 75% : 25%, dan 65% : 35%). Hasil penelitian menunjukkan bahwa nilai kalor tertinggi terdapat pada variasi komposisi serbuk gergaji (SG) 85% : 15% sampah organik (SO) sebesar 49kal/gr, sedangkan kadar air tertinggi 20,52% dan kadar abu tertinggi 14,57% pada variasi komposisi serbuk gergaji (SG) 65% : 35% sampah organik (SO). Hasil karakteristik kimia nilai kalor, kadar air dan kadar abu biobriket tidak memenuhi persyaratan SNI 01-6235-2000. Kata kunci: biobriket, energi alternatif, sampah organik, serbuk gergaji
