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

ABSTRACT Geographically, South Minahasa district lies between 1 ° 17'18.22 "north latitude and 124 ° 54'48.84" east longitude, with a total area is 1188.67 km2, or approximately 8% of the total area of North Sulawesi (15.069.00 km2 ), with the coast in the north and south and the high plains, where irrigated rice fields provide an abundant harvest. Nature and the weather in this area is suitable for agricultural. At almost all districts  various agricultural crops can grow. Rice cultivation is mostly irrigated, in addition there is still also a rainfed. Planting is done two to three timesa year  and sometimes rotated withother food  crops. Food crops cultivated by the inhabitants consist of rice, corn, potatoes, and other food crops as well as various other horticultural crops. Besides Rice, South Minahasa also produces maize and cassava in relatively large quantities. Thus, the food crop farmers in South Minahasa can choose from various types of crops that can be cultivated in their agricultural lands. This study was conducted in August until September 2016 in South Minahasa regency. Required data were collected using survey methods, and analyzed with linear programming method using  solver application in Microsoft excel. Based on the research results, if the labor supply increased by 2 per family farmers and harvesting is done by machines  the farmer income per year increased from Rp 720 million, - to Rp 1.84 billion, - obtained from the cropping pattern of 15 hectares rice and 10 hectares corn for Musafir 4 farmer groups. the same goes for the Torout Jaya farmer groups, revenue per year increased from Rp 582 million, - to Rp 2.3241 billion, - which is obtained from the cropping pattern 17 hectares of rice and 20 hectares of soybeans.  Keywords : Optimization Farming, Linear Programming, Solver

Abstract

Abstract Walnut are native to Indonesia, which grows in many parts of the east, such as North Sulawesi and Maluku. Walnut shell is one of the Agricultural solid waste that has not been used optimally. Walnut shells have a physical structure that is hard enough to allow it to be used as charcoal, the use of walnut shells is still very lacking, so it takes the process of processing walnut shells into a more useful product. The purpose of this study is to make walnut shell briquettes and analyse content, ash content, briquette fuel that meet the Indonesian National Standard (SNI). The research was carried out for six months in two places, namely the Engineering Laboratory of the Faculty of Agriculture, Sam Ratulangi University Manado and the Laboratory of the Industry and Trade Standardization Research Institute.this study uses a descriptive method with different amounts of flour treatment (50 grams, 100 grams, 150 grams) and aims to observe the effect of adhesive material (tapioca flour) on the results of research, walnut shell briquettes have met the Indonesian National Standard (SNI). Keywords : walnut shell, tapioca adhesive, bioarang briquette

Abstract

Abstract Corn (Zea mays L) is one of the cereal plants that grows almost all over the world and is classified as a species with large genetic variability. In Indonesia corn is the second staple food after rice. Besides that, corn can be used as animal feed ingredients and industrial raw materials (Fadhullah Muhammad 2016). Sieving is the separation of the mixture of solid particles that have various sizes of material using a sieve. The sieving process is also used as a cleaning tool, the separator of waste which is different in size from the raw material. The purpose of this study was to modify and technically test the corn seed cleaning system using the electro motor sway and different air flow speeds using a fan. This research has been carried out in the Agricultural Engineering Workshop, Agriculture Technology Department of the Faculty of Agriculture Unsrat for 3 months from May to July 2018, including the making of sieving tools, implementation of sieving experiments and analysis of research data. This study includes the modification and technical testing of corn seed cleaning equipment with a combination of swaying and wind blowing sieve systems, using 3 different air flow rates from different fans with 3 (three) replications, namely: 1. Air flow velocity 1.3 m / s ( A), 2. Air flow velocity 2.1 m / s, (B), and 3.Air flow velocity of 3.5 m / s (C). The speed of air flow in this study is not the same level, only adjusting the speed of the fan (fan) made by the factory  Keywords: Modification of tools, sway sieve system, wind gusts

ABSTRACT This research aims to analyze the differences from the type of material and mass of briquette molding toward the characteristics of burning briquette. Burning characteristics include temperature of burning, burning time, boiling time of water, and thermal efficiency resulting from. The method used in this research is descriptive experimental method with coconut shell and corncob as raw material for briquettes. This study uses the difference in mass of material when molding briquettes. The mass of material at the time of moulding is divided into 50 g and 40 g. The results indicate the quality of briquettes as follows, moisture content of 7.22%-8.31%, density of 0.52 g/cm3 – 0.78 g/cm3, a heat value of 6,259.81 cal/g – 6,906.56 cal/g. Briquettes A (coconut shell with a mass printing of 50 g) produces the lowest moisture content 7.22%, the highest density 0.78 g/cm3, as well as the greatest heating value i.e. 6,906.56 cal/g. The results of the burning indicate optimum fire temperature reached 934.8 oC from briquettes B (coconut shell with a mass printing of 40 g). Average the time of boiling 2 litres of water ranged from 22.16 minutes – 27 minutes with a total of boil water between 12-14 liters, the burning time ranging between 167 minutes/kg – 220 minutes/kg briquettes, as well as thermal efficiency achieved 14.03% – 15.15%.  Keywords: Briquette, burning characteristics, thermal efficiency.

Abstract

ABSTRACT Nutmeg seeds are a commodity that are well known in Indonesia, making nutmeg seeds as an important spice since the past. This study aims to analyze several drying parameters in the nutmeg drying process such as temperature, relative humadity, reduction in weight of the material, drying rate, intensity of solar radiation in drying using solar energy and LPG (Liquefied Petroleum Gas). This research was conducted at the Agricultural Engineering Laboratory, Faculty of Agriculture at Sam Ratulangi University. This research uses descriptive method of temperature in the dryer on rack 1 ranges from 35.7°C - 59.2°C, rack 2: 35.6°C - 58.4°C and rack 3: 33.6°C - 46.6°C while the ambient temperature from 30°C - 37°C. The relative humadity of the environment during drying is 60% - 88% and in the dryer is, rack 1: 25% - 66%, rack 2: 23% - 66%, and rack 3: 26%- 74%. During the drying process there is a decrease in water content from 61.52% bk dropped to an averange rack 1: 34.32%, rack 2: 33.34% and rack 3: 36.42%. The highest intensity of solar radiation reaches is 872.25 watts/hour and the lowest is 407.05 watts/hour. Drying using solar energy and LPG will speed up the drying process.
