Abstract

ABSTRACT Coconut oil is one of the potential coconut processing products to increase added value for farmers in the North Sulawesi area. The processing of coconut oil has actually been done quite a lot by North Sulawesi farmers, but they still use traditional equipment. This method of processing takes a long time and is inefficient. The government has distributed mechanical equipment for smallscale coconut oil processing and socialized it to several farmer groups. The purpose of this study was to technically analyze the performance of small-scale coconut oil processing systems for 2 farmer groups. This research was conducted with an experimental method in which some of the equipment was tested for its capacity. The material used is coconuts aged 11-12 months, as many as 150 coconuts. Coconut processing on the existing equipment system was carried out in 3 (three) replications, with the number of each replication being 50 coconuts. The stages of coconut processing carried out in this study were, peeling, washing, cleaning, draining, squeezing, separating and allowed to stand for 24 hours. After 24 hours, the resulting coconut cream is put in an oil cooking machine and heated at an average temperature of 1500 C for 2 hours. The results of cooking are filtered, to take the coconut oil. The results showed that the small-scale coconut oil processing equipment system can be maximized to produce commercial coconut oil products. The performance of the tool is influenced by the existing power transmission engine, and the skill of the operator in each stage of work is very important. It is recommended for maximum use of the equipments, given special training to the operators. Keywords: Coconut Oil, Processing Equipment Systems, Farmers, Operators.

Abstract

ABSTRACT Clove plants contain essential oils found in flowers (10-20%), stalks (5-10%), leaves (1-4%). In many places, the clove leaf is not used optimally. This can be seen in clove plantations where the fallen leaves are left alone in the garden. Clove leaf processing equipment into essential oil is relatively limited, therefore a clove leaf distiller was designed the steam method. The yield and performance of the tool need to be measured, to find out the performance of the tool design that has been made. For this reason, this study aims to conduct a technical test of the tool with variations in the volume of water that will be vaporized differently by measuring the temperature of the kettle and the time the first drop of condensate occurs, the volume of oil, the temperature of the condenser, the yield and the 2 color of the oil. This study used an experimental method by conducting 3 (three) experiments with different boiler water volumes, P1: 15 liters of water, P2: 35 liters of water, and P3: 45 liters of water with 3 (three) replications in each experiment. The research data are presented in the form of graphs and tables. The results showed that the higher the volume of boiler water, the longer the time the first droplet of condensate occurred. At a boiler water volume of 15 liters, the first droplet of condensate occurs at a boiler temperature of 82.56 °C and the time of the first droplet of condensate occurs at the 95th minute, while the volume of boiler water is 35 liters and 45 liters occurs the first droplet of condensate at a boiler temperature of 66.33 °C and 91.33 °C and the time of the first droplet of condensate in the 100 minute and 110 minute. The volume of clove essential oil produced is increasing at a volume of 45 liters of boiler water as much as 6 ml, while the volume of 35 liters of boiler water is 5.3 ml and the volume of boiler water is 15 liters as much as 3 ml. The condenser temperature produced in all three boiler water volume experiments was 10 °C. The highest amendment was found in the volume of boiler water of 45 liters, which was 0.848%, in the volume of boiler water of 35 liters, which was 0.646% and the volume of boiler water of 15 liters, which was 0.621%. The color of the resulting oil is dark brown. Keywords : Essential oil, Clove leaf, Technical test, Steam method

Abstract

ABSTRACT Indonesia has the potential of abundant natural resources in agriculture such as coconut plantations. The area of coconut plantations in Indonesia reaches 3,728,600 ha. Currently, Indonesian agricultural commodities are well known and their demand is increasing from various countries such as technological developments. Indonesia is able to produce 18.3 million tons of coconut in a year this number can increase from year to year so that Indonesia becomes the largest producer in this industry. In North Sulawesi, coconut yields in 2021 will reach 265,761 tons. North Sulawesi produces a lot of coconut, mostly in the form of copra. Coconut coir is used as a raw material for making charcoal briquettes that are environmentally friendly, easy to obtain and have high economic value. Based on the above, it is felt necessary to conduct research on coco briquettes by looking at the effect of mixing adhesives on the quality of briquettes. So the purpose of testing the water content, calorific value, rate of combustion and flame test of coconut fiber briquettes and starch as adhesives. The lowest air content is in the percentage of 95%: 5%, which is 18.97%, while the highest air content is in the mixing proportion of 90%: 10%, which is 19.56%. The results of the average briquette test showed that the lowest calorific value was 2244,614 cal/g using 5% adhesive, while the highest calorific value was 3225,8648% using 7.5% adhesive. The fastest average burning rate was in the 5% treatment with a time of 0.00126140 (g/s) and the longest burning rate was in the 7.5% treatment with a time of 0.001702662 (g/s). The fastest Self Burning Time is at a mixing proportion of 90%:10% with an initial ignition time of 05 minutes 10 seconds, while the longest Self Burning Time is at a percentage of 95%:5% with an initial ignition time of 06 minutes 08 seconds. The results of the test for boiling 1 liter of water, the sample mixture of 95% coconut coir briquettes: 5% starch takes a long time to boil 1 liter of water, which is 27 minutes 45 seconds. For 90% coconut coir briquette mixture: 10% starch, it takes a little faster, namely 25 minutes 33 seconds. Keywords: Charcoal briquettes, Coco coir, Initial ignition time, Biomass energy

Abstract

Many coconut husks in coconut-producing área have not been maximally utilized, especially on a small scale for farmers. It happened due to the difficulty of obtaining simple small-scale coconut decomposing machines, and the region must import it from other regions. As a result, the utilization of coconut fiber in fiber and cocopeat is still minimal. Plus, when bringing in from outside, the logistics cost of the coconut husk decomposing machine is still high. This research aims to conduct a techno-economic analysis of a small-scale coconut husk decomposer from the machine designed and made. The research method was using the experimental method. The results showed that the equipment can produce cocofiber and cocopeat with 600 kg of husk per day for 6 hours of use. The results of economic calculations based on the IRR value, the net B/C ratio, and the payback period show that this machine is feasible to be developed on a small scale for Farmer groups. Technologically, this machine is simple and relatively easy to operate. Further research hopes this machine will prove its durability over long, heavy work periods.
