Abstract

ABSTRACTBiomass energy is an alternative energy that is converted from biological material derived from recently dead organisms into energy to be used as a power plant. The purpose of this study of was to analyze the energy consumption of gas produced biomass and its comprasion with diesel fuel. Alaysis was done by varying loading on diesel power plants with a substitution gas from gasification of biomass from coconut husk. Conversion of biomass energy as a source of electrical energy was obtained from the downdraft gasifer. This research uses experimental methods to analyze the consumption of diesel fuel in some electrical loading with the substitution of diesel with the coconut husk produced gasification. Electrical load variation are : 500W, 1000W, 1500W, 2000W. the results of the study with 12,34% water content show that the higher the electrical load is used, the grater the fuel used. The consumption of diesel fuel can be reduced by using biomass gasification. The diesel reduction generated at a load of 500W is 50,87, and the reduction of diesel fuel consumption of loads of 1000W, 1500W and 2000W are 48,81%, 46,98% and 44,48%. It is advisable to further simplify the process of providing raw materials which is prepared manually, due reques a hard effort to unifom the size of coconut husk. Keywords : gasification, solar fuel

Abstract

ABSTRACTThe purpose of this study was to determine the amount of loss of rice at harvest time, lostbecause it is not harvested, lost because of lagging on the machine, lost in the threshing. andthe capacity and efficiency in the field using the Mini Combine Harvester. Research wasconducted during April-May 2016, in the of Torout village, South Minahasa district. UsedSako rice which is the local varieties. Mini Combine Harvester Maxxi Type-M is used as aharvesting machine. Results showed that losses at the stage of harvesting or cutting, (2.09 ±0.81)%, standing crop loss (1.08 ± 0.17)%, un-thressed loss (1.44 ± 0.40)% and the threshingloss (0.003 ± 0.002)%.

Abstract

ABSTRACT Extreme climate change is one of the factors that determine the quality of the plant. In this case one of the main factors driving plants to photosynthesise is light. (Alhadi, 2016). In general, the provision of ideal conditions is still limited to the protection of plants from extreme weather using greenhouse or better known as the greenhouse or plant house. Plant house is one way to provide an environment closer to the optimum conditions for plant growth. According to (Fides, 1992) the addition of artificial light to create long day conditions in the equator area of about 3-4 hours with the intensity of light with a range of 32-108 lux. Long day manipulations can be made using light from both incandescent and tube lamp sources (Kofranek, 1980). The purpose of this research is to study the substitution of sunlight with HID (High Intensity Discharge) lamp and LED (Light Emiting Diode) to optimize the growth of Cherry tomato plant in tropical plant house made from polyethylene (PE) roof. The results showed that the total intensity of light inside the plant house was obtained from the total intensity of the incoming sunlight in the plant house plus the total HID light bulb that is equal to 217.86 MJ/ m2 (treatment N2) and total sunlight plus total LED lamp light that is equal to 208.58 MJ / m2 (N3 treatment). But the intensity of this light is still much smaller than the total intensity of light outside the plant house (treatment N0) that is equal to 526.65 MJ / m2
