Development of the Biogas-Energized Livestock Feed Making Machine for Breeders

Abstract

The need for beef in Indonesia continues to increase. In 2020, it will require imports of 300 thousand t of meat or the equivalent of 1.7 × 106 cattle a year. To overcome the problem, the biogas-energized livestock feed making machine (copper) was designed. The advantage of this copper is the process of making the livestock feed can efficient and effective. Results of the calculations, known that with increasing miller rotation output, the resulting capacity shows an increase. Also, it can use drive motors that are available on the market with a power capacity of 50 W. Hence; this machine is very efficient in the use of electricity, high economic value, convenient and easy move to other places. Electricity for the engine is designed with renewable energy, namely biogas from co-digestion substrates namely animal feed waste, kitchen waste, cow dung and excreta disposal from septic tanks. This co-generation is expected to improve the life of the breeders

The Technical Design Concept of Hi-Tech Cook Stove for Urban Communities using Non-Wood Agricultural Waste as Fuel Sources

“…The application of biogas is feasible to manage kitchen waste and excreta disposal from septic tanks in urban areas for environment friendly [30][31][32][33]. The two-stage digester system is recommended because kitchen waste tends to be acidic and float [34,35].…”

Design of Rotary Dryer for Sand Drying using Biomass Energy Sources

“…Hence the thickness and lifetime can be determined. The maintenance time of this equipment need to pay attention, hence it can more durable and be used longer [12][13][14][15]. Determination of the number of baffles, size and position of placement in the rotary drayer shell chamber determine the success of the drying process.…”

“…Among them are those who developed the Organic Rankine Cycle (ORC) turbine design, which is devoted to producing electrical energy from heat energy sources with a temperature of less than 100 ºC [12]. There are also researchers who develop drying machine equipment that can be operated using electrical energy generated from solar energy [13], and also develop livestock feed processing equipment that operates using electrical energy generated from biogas energy [14], and there are also researchers who develop equipment for moving goods that are operated using electrical energy generated from other renewable energy sources [15,16]. Even now, a smart microgrid system equipment has been developed that can utilize solar energy and wind energy to produce electrical energy combined in a hybrid manner [17].…”

“…Reference [14][15][16][17] has stated biogas that drives several types of agricultural equipment. Precisely [15] recommends fish waste at the Fishing Ports (Pelabuhan Perikanan), Fish Auctions (TPI -Tempat Pelelangan Ikan), or Fish Auctions Center (PPI -Pusat Pelelangan Ikan) as feedstocks for the biogas digester.…”

“…The performance of this rotary dryer, can be known through the following formulas [12][13][14][15]. The motor rotation output calculated using the Equation (1).…”
