Abstract

Organic fertilizer is a fertilizer that is expected to improve the physical, chemical, and biological properties of the agricultural land resources, which is undergoing fertilityand productivity degradation. Compost is one of the organic fertilizers produced from the biological decomposition process by a consortium of microorganisms, includingfunctional microorganisms. To make it easier for farmers and efficiency in the use of organic fertilizer, organic fertilizer will be further processed into granular form and is called Granules Organic Fertilizer (POG). In the manufacturing process, namely at the time of drying using a rotary dryer, was suspected of using high temperatures to kill microbes (including functional microbial) that naturally exist in the organic compost fertilizer (POK), which is the raw material for POG. To increase the presence of functional microbial populations, the POG which has produced before, then added with bio fertilizer that is rich in microbial functional. This research was conducted to determine and evaluate the total microbial population and functional microbial in pure POK, compared with the total microbial population and functional microbial in the POG are enriched with bio-fertilizer. The results showed: There is an indication to the higher number of total microbial population in the POK, who showed by total fungi population, compared with the POG. The number of functional microbial population, as shown by bacterial phosphate solvent and non-symbiotic bacteria that are fastening N in POK, very high and already meets the criteria to be called as a biological fertilizer. The amount is not significantly different compared to the POG that is already enriched with bio fertilizer that is rich in microbial functional. There is an indication of the influence of high heating using a rotary dryer, in the POG manufacturing process against the decreasing of the amount of microbialpopulation that are resulting in the POG, including functional microbial

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

Abstract

The most important part is manufacturing since PV modules areproduced under very height energy consumption characteristic.Photovoltaic energy production is suppose to be an environmentallyfriendly energy system with no emissions and no waste production, cleanand noiseless but ins important to ensure that manufacturing is not goingto be more harmful for the environment than operation advantages. Then itis very important to know if the product is going to be economically andenvironmentally viable for the overall life cycle. For the manufacturingprocesses environmental impact, three different studies have been carriedout: Energy Analysis, Energy Related Emissions Analysis and Materialflow analysis.Operation. Advocates of renewable solar system argue thatduring operation the environmental impact of this technology is minimal incomparison with other form of renewable energies. Decommissioning. At theend of the lifetime of the modules, they must be dispose in a sensitiveway. At the moment there are no many option for recycle the siliconwafer. Aluminum frames can be recycled separately in the same wayas this material normally is, glass could be recycle i technologies would exist to separates the glass from the adherent EVA and othermodule components.
