Abstract

The growth of the dairy industry in Indonesia is expected to be an attraction for the local farmers. The increasing number of breeders will have a negative impact on the increase of waste generated.Waste from the farm business can be a solid waste, gas and liquid waste. Animal husbandary waste can be processed to produce biogas as an energy alternative to oil burner and premium drive electricgenerators. From the measurement of CH4 content ranged from (56.67 - 62.8 %), while the CO2 content ranged between (36.36 - 42.64 %). This value is between methane and carbon dioxide content of the theoretical limit. Gasbio volume generated during the 24 hours ranged of 4.218 - 6.198M3, or the average of the gas produced as much: 5,096 M3 per day. Electricity generated = 3.822 kWh. Electricity power genset of 500 watt can burn for 7 hours. The results of laboratory analysis of sludge solids can be seen that the C / N ratio is still relatively high at 42.6, whereas the C / N ratio, which allowed ranged of 15-25. The C value is very high due to the organic composting process is too short, the element N is very low because the nitrogen is still in the complex chain that required the administration of N fastening bacteria such as : Azotobacter, Azotomonas, Pseudomonas.Keywords: cattle manure, biogas, energy listrk, compostAbstrakPertumbuhan industri susu olahan di Indonesia diharapkan akan mampu menjadi daya tarik bagi peternak lokal. Meningkatnya jumlah peternak akan berdampak negatif terhadap meningkatkanlimbah yang dihasilkan. Limbah dari usaha peternakan tersebut dapat berupa limbah padat, gas dan limbah cair. Limbah peternakana dapat diproses untuk menghasilkan biogas sebagai energi alternatif pengganti minyak kompor dan premium menggerakan generator listrik. Dari hasil pengukuran kandungan CH4 berkisar antara (56,67 – 62.8%), sedang kandungan CO2 berkisar antara (36.36 – 42,64%). Nilai tersebut berada diantara kandungan metan dan karbon dioksida pada batas secara teori. Volume gasbio yang dihasilkan selama 24 jam berkisar antara (4,218 - 6,198) M3,atau rata-rata gas yang dihasilkan sebanyak : 5,096 M3 perhari. Listrik yang dihasilkan = 3,822 kWh. Genset dengan daya 500 Watt maka listrik bisa menyala selama 7 jam. Dari hasil analisislaboratorium terhadap padatan sludge dapat diketahui bahwa C/N ratio tergolong masih tinggi yaitu 42,6, padahal C/N ratio yang diizinkan berkisar antara 15 – 25. Hal ini disebabkan karena Corganiknya sangat tinggi akibat proses komposing masih terlalu singkat, unsur N sangat rendah karena nitrogen masih dalam rantai yang kompleks sehingga diperlukan pemberian bakteripenambat N, diantaranya adalah: bakteri Azotobacter, Azotomonas, Pseudomonas.

Abstract

Along with the development of biogas and its utilization, biogas reactors also evolved from conventional reactor types to high rate performance reactors, adapts to the needs of increased efficiency and also the characteristics of organic waste that is difficult if processed using ordinary reactor. However, this type of reactor basically has 3 types, namely fixed bed (packed-bed, anaerobic filters, fixed-film), fluidized bed reactor, and UASB/ Upflow Anaerobic Sludge Blanket reactor. From these high rate performance reactors, fixed bed reactor is the type that is pretty much developed and implemented in Indonesia, especially for treating organic wastewater from small industries, for example tofu, tapioca and slaughterhouses. Implementation of fixed bed reactor for the tofu industry until today has reached as much as 5 units that serve the needs of about 132 households in Banyumas District, Central Java Province. The fixed bed reactor’s performance is quite high if it is evaluated from biogas yield and the efficiency of the organic content in tofu industry’s wastewater. Implementation, dissemination, and replication of this reactor for treatment of other types of organic waste or other areas have the potential to support government programs in GHG mitigation actions, renewable energy sources provision, environmental protection and the development of energy self-sufficient villages.Keywords : biogas reactor - performance high - rate, fixed bed reactors, tofu industryAbstrakSeiring dengan perkembangan biogas beserta pemanfaatannya, reaktor biogas juga berkembang dari jenis reaktor konvensional hingga reaktor berunjuk kerja tinggi (high rate performance) menyesuaikan dengan kebutuhan peningkatan efisiensi dan juga karakteristik limbah organik yang sulit jika diolah dengan menggunakan reaktor biogas biasa. Namun, pada dasarnya reaktor ini memiliki 3 jenis, yaitu reaktor unggun tetap (fixed bed, packed-bed, anaerobic filter, fixed-film), reaktor unggun terfluidisasi (fluidized bed reactor), dan reaktor UASB (Upflow Anaerobic Sludge Blanket). Dari ketiga jenis reaktor berunjuk kerja tinggi tersebut, reaktor jenis unggun tetap adalah jenis yang cukup banyak dikembangkan dan diimplementasikan di Indonesia, terutama untuk mengolah limbah cair organik yang berasal dari industri kecil, misalnya tahu, tapioka dan rumah potong hewan. Implementasi reaktor unggun tetap untuk industri tahu hingga saat ini telah mencapai jumlah 5 unit reaktor yang melayani kebutuhan sekitar 132 Rumah tangga di Kabupaten Banyumas secara berkelanjutan. Kinerja reaktor unggun tetap ini dapat dikatakan cukup tinggi jika dinilai dari perolehan biogas dan efisiensi penurunan kandungan organic dalam limbah cair tahu. Program implementasi, diseminasi, dan replikasi reaktor ini untuk pengolahan jenis limbah organik yang lain atau daerah lain memiliki potensi dalam mendukung program pemerintah dalam aksi mitigasi Gas Rumah Kaca, penyediaan sumber energi terbarukan, perlindungan lingkungan dan pengembangan desa mandiri energi.Kata kunci : biogas, reaktor high-rate-performance, reaktor fixed bed, industri tahu
