ABSTRACT This study aims to design and make a soybean planting tool with aspects that need to be considered such as planting conditions, number of seeds per planting hole, planting distance, seed conditions when planted, and planting efficiency. The expected outcome of this research is that it can produce soybean planting tools that can be used by farmers and academics to support government programs in increasing national soybean production. The process of designing and manufacturing tools was carried out at the Agriculture Technology laboratory and planting or testing the performance of the tools carried out in the Unsrat village of Wailan experimental village in North Tomohon District. This research began from April 8 to May 20 2019 for the manufacture of tools and the planting process was carried out on May 22, 2019 using a planting tool that had been made with a hand tractor as a towing force and 3 weeks of observation of growing soybeans. The soybean varieties grown are Dega 1 soybean variety which is the best variety according to 2017 R & D data. Data obtained after the process of planting and observing soybeans for 3 weeks was in the form of field efficiency data of 81.57%. with the percentage of seeds growing 61.59% and the percentage of seeds not growing 38.41%. The total percentage of seed growth is closely related to the performance of the tool because the tool still has a deficiency in the metering device that has a gap with the hopper resulting in the seeds entering the gap breaking and unable to grow when planted.

ABSTRACTEnergy is a crucial global issue. Demand for energy increases every year. According todata collected by the Ministry of Energy and Mineral Resources (2006) Indonesia's oilsupply amounts to a mere 9 billion barrels, which will run out with continued consumption.To decrease dependency on fossil fuels, the government has issued Peraturan PresidenRepublik Indonesia number 5 year 2006 about National Energy Policies to developalternative renewable energy resources. Energy experts around the world are now researchingand developing renewable energy, one of which is biogas. This research is done in Totabuanvillage, district of Lolak, Bolaang Mongondow regency, using experimental methods withdescriptive analysis of the formation of biogas using biodigester technology with a permanent12 m3 dome-type reactor. Biogas started forming on the 9th day, up to the 26th day, with 12m3 of raw materials, which is a 1:1 mix of cow feces with water (6 m3 cow feces and 6 m3water), and yielded 4,68 m3 of biogas that can be used to cook for 12,3 hours. Each 1 m3 ofbiogas can be used to cook for 2,63 hours. Biogas yield is 39%Keywords: Energy, Renewable, Biodigester, Biogas.
