Abstract

The breakdown of candlenut seeds from the shell is very important to note due to the increasing consumption needs of candlenut seeds in the market has not been able to be balanced with the quality of the breakdown of good candlenut seeds. The purposed of this research was to identified the physical and mechanical properties of candlenut, analyzed the strength of the candlenut seeds that was in the treatment, analyzed the mass of the candlenut seeds which stick to the shell, analyzed the level of integrity of the candlenut seeds. This research was conducted using factorial randomized block design (RAKF) method with 2 factors. The first factor was the variation of NaOH concentration, while the second factor was the time of immersion ice water. Pressed load testing of candlenut shell used brazillian test, from this research was obtained the result of press load candlenut seeds with variations of NaOH immersion and the immersion time of ice water 10 and 45 minutes on average were 31.28 N and 22.30 N, while the load control was 44.692 N. Mass the seed core that was still sticky to the shell with the treatment given was an average value of 0.114 gr (3.8%) and 0.033 gr (1.2%), while the control is 1,753 gr (63%). The whole candlenut seeds core results with the given treatment were 7 grains (31.8%) and 15 grains (64%), whereas the control did not get the whole candlenut seeds core. The results of research is shows that the parameters of the increase in NaOH concentration does not have a significant effects but when compare with the control of NaOH it is very significant for the breakdown of candlenut, while the time parameters have a very significant effects.Keywords: NaOH, Ice water immersion, The process of breaking candlenut,

Abstract

Waste is a remnant produced from human activities such as; household, commercial, office, industrial, etc. Waste is considered to have no value because it cannot be reused so that some people do not care about the impact of waste. The accumulation of waste that accumulates every day will harm the environment and society. The incoming waste to be processed at Talangagung Landfill comes from: Settlements, markets, Sub-Landfill, hospitals, offices, companies and highway services. In 2018 the Talangagung landfill receives 48,063.37 tons/year of waste. The largest source of waste entering the Talangagung landfill comes from settlements of 54%, the market by 22%, sub- landfill by 15%. Talangagung landfill educational tourism is one of the pilot landfills that use a controlled landfill system to manage waste to minimize negative impacts on the environment and society. The waste that enters the Talangagung landfill will be processed into biogas. Renewable energy produced from Talagagung landfill in the form of methane gas arising from waste decay. The potential for waste management into biogas can be calculated using the scholl canyon method from Talangagung landfill waste data in 2018. The results of the calculation of the gas produced are 183,558 m3 / year. The gas produced is assumed to only be captured at 75% with the composition of methane gas at 50% -55% of the total gas produced. The resulting methane gas has decreased to reach 31,897.6 tons/year in the 40th year. This is because waste that experiences an anaerobic phase experiences nutrient reductionKeywords: Controlled landfill, Renewable energy, Methane, Waste
