Abstract

Penduduk Indonesia menyumbang sampah sebesar 150-184/kg/orang.tahun. Sebagian besar sampah di Indonesia didominasi oleh sampah makanan dengan persentase 44 % dan di Jawa Timur sebesar 49,08%. Sampah makanan yang tidak dikelola akan menyebabkan masalah seperti masalah kesehatan, masalah sosial, dan masalah lingkungan. Pengomposan menjadi solusi dari pengolahan sampah makanan. Pengomposan sendiri dibagi menjadi 2 menurut suplai oksigen yaitu ketersediaan oksigen cukup (aerobik) dan fermentasi (anaerobik). Pengomposan dibagi menjadi dua metode yaitu windrow composting atau secara konvensional dan in-vessel composting. Metode in-vessel composting yaitu metode pengomposan dalam suatu reaktor menjadi metode yang digunakan dalam skala besar atau menengah. Metode ini dapat membuat kompos dalam waktu yang cepat. Faktor-faktor yang dapat mempercepat pengomposan yaitu aerasi dan pengadukan. Penelitian ini bertujuan untuk mengkaji pengaruh pengadukan dan aerasi pada kualitas kompos dan kualitas air lindi. Variasi aerasi yang digunakan yaitu 1 L udara/menit dan 1,5 L udara/menit. Variasi pengadukan yang digunakan yaitu 5 hari sekali dan 10 hari sekali. Parameter pada kompos yang diamati yaitu kadar air, kadar total karbon, kadar total nitrogen, rasio C/N, suhu, pH, dan tinggi kompos. Parameter pada air lindi yang diamati yaitu nilai COD dan kuantitas air lindi. Berdasarkan hasil penelitian, diperoleh bahwa adanya aerasi berpengaruh terhadap nilai pH pada kompos dan rasio C/N. Frekuensi pengadukan berpengaruh terhadap penurunan temperatur dan nilai pH. Aerasi dan frekuensi pengadukan tidak berpengaruh terhadap kuantitas dan kualitas air lindi.

Indonesian population contributes waste of 150-184 /kg / person. per year. Most of the waste in Indonesia is dominated by food waste with a percentage of 44% and in East Java 49.08%. Unmanaged food waste will lead to problems such as health problems, social problems, and environmental problems. Composting is a solution to food waste processing. Composting itself is divided into 2 according to oxygen supply, namely sufficient oxygen availability (aerobic) and fermentation (anaerobic). Composting is divided into two methods, namely windrow composting or conventionally and in-vessel composting. The in-vessel composting method is a method of composting in a reactor into a method used on a large or medium scale. This method can make compost in a fast time. Factors that can speed up composting are aeration and turning. This study aims to examine the effect of turning and aeration on compost quality and leachate. The variation of aeration used is 1 L of air / minute and 1.5 L of air / minute. The variety of turning used is once every 5 days and every 10 days. The parameters of the observed compost are moisture content, total carbon content, total nitrogen content kjeldahl, C/N ratio, temperature, pH, and compost height. The parameters of leachate water observed are COD value and leachate quantity. Based on the results of the study, it was found that the presence of aeration affects the pH value of the compost and the ratio of C / N. The frequency of turning affects the decrease in temperature and pH value. Aeration and turning frequency do not affect the quantity and quality of leachate water.
