“…3. Showed that on the 10th day of composting the pH of compost arrived at its peak value which is clearly related to temperature, also maybe caused to encourage NH3 production during composting (Spencer and Van Heyst, 2013). The pH value declined to stabilize with the end result at 100 days being 6.9, 7.4, 7.1 and 7.0 for composting treatment T1, T2, T3 and T4, respectively.…”

This study aims to study the effect of adding rock phosphate and plant growth-promoting rhizobacteria (PGPR), in the physical and chemical properties of the corn residues compost during aerobic decomposition. Four composting heaps were included in this study as it follows, 1) traditional method composting heap (T1), 2) heap was supplied with rock phosphate (T2), 3) heap was supplied with rock phosphate + Bacillus megatherum culture (T3), and 4) heap was supplied with rock phosphate+(Bacillus.megatherum, Azospirillum lipoferum, Azotobacter chroococcum) mixed cultures (T4). All compost treatments showed an increase in temperature right after composting started. The heap treated with three bacterial inoculums (T4) reached the highest peak values of 62.2°C on day 12 compared to other treatments. At the end of the composting period T1 recorded the lowest value of bulk density (533 kg/m 3 ) compared to other treatments. The pH value declined to stabilize with the end result at 100 days being 6.9, 7.4, 7.1 and 7.0 for composting treatment T1, T2, T3 and T4, respectively. The initial C/N ratio was 61:1 for all composting treatments, and the final values of total C/N ratio after the 100 days were 15:1, 14:1, 12:1 and 10:1 for composting treatments T1, T2, T3 and T4 respectively. Compost supplied with rock phosphate and three bacterial inoculums (T4) reached has more N, P and K content compared to other composting treatments T1, T2, T3. These results indicated that adding rock phosphate and (PGPR) to corn residues during composting improve nutritional value of the resulting compost.

“…Penurunan kadar nitrogen pada limbah makanan karena adanya proses penguapan nitrogen bersama kadar air dan adanya peningkatan pH pada bahan sehingga adanya volatilisasi N sebagai NH3 (Spencer dan Heyst, 2013). Selain itu waktu pengolahan mempengaruhi kadar nitrogen dimana semakin lama proses pemanasan akan semakin berkurangnya kadar nitrogen akibat penguapan yang terjadi dengan waktu yang lama hingga bahan menjadi kering.…”

Sampah saat ini menjadi permasalahan lingkungan. Salah satu sampah yang banyak dihasilkan adalah sampah organik berupa sisa makanan yang berasal dari rumah tangga maupun restoran atau rumah makan. Pengelolaan sampah skala individu atau kelompok sangat diperlukan untuk meminimalisasi volume sampah yang masuk ke Tempat Pemrosesan Akhir (TPA). Pada penelitian ini dilakukan pengolahan sampah makanan dengan alat Food Waste Recycler (FWR) untuk menurunkan massa limbah dengan menggunakan metode conductive drying pada suhu 70 o C selama 5 jam (S1) dan 10 jam (S2). Berdasarkan penelitian menunjukkan faktor-faktor yang mempengaruhi hasil dari pengolahan limbah makanan dengan menggunakan alat FWR, yaitu massa limbah, suhu,

“…Kandungan N total, P total, dan K total pada seluruh reaktor mengalami peningkatan selama pengomposan. Akan tetapi, pada kandungan N total mengalami penurunan pada hari ke-5 akibat volatilisasi N sebagai NH 3 karena meningkatnya pH pengomposan (Spencer & Heyst, 2013). Mikroorganisme membutuhkan nitrogen dalam pembentukan protein (Kumar, et.…”

Rasio C/N merupakan salah satu faktor penting pada proses pengomposan dan produksi listrik dalam compost solid phase microbial fuel cells (CSMFC). Rasio C/N menggambarkan nutrisi yang tersedia bagi mikroorganisme dalam CSMFC. Besarnya nilai rasio C/N yang terdapat dalam substrat yang digunakan mempengaruhi kinerja CSMFC. Penelitian ini bertujuan untuk menentukan nilai rasio C/N yang optimum terhadap kinerja CSMFC. Variasi nilai rasio C/N yang digunakan yaitu 30:1, 40:1 dan 50:1. Kadar air diatur pada 60 %. Penelitian dilakukan secara batch selama 23 hari. Parameter yang diujikan berupa suhu, pH, kadar C Organik, N total, P total, K total, rasio C/N, power density, dan Coulombic efficiency. Hasil penelitian menunjukkan bahwa kinerja CSMFC yang optimum terdapat dalam reaktor dengan rasio C/N 30:1 dengan nilai suhu, pH, kadar C Organik, N total, P total, K total, power density, dan Coulombic efficiency secara berturut-turut sebesar 7,1, 27,5 OC, 20,31%, 1,63%, 0,19%, 0,21%, 12,47, 48,02 mW/m2 dan 0,19%.
