Abstract

Crystal coconut sugar is a local Indonesian food product that has enormous potential, not only domestically but also abroad. The temperature and cooking time in the production of ant sugar are things that need to be considered because they are related to the efficiency and quality of ant sugar products. Therefore, the required fuel has a high-efficiency value so as to produce high-quality ants. This study aims to compare the performance and energy efficiency as well as the quality of ant sugar products produced from cooking sap using a pressurized LPG stove with a sawdust-fueled stove. Parameters measured include temperature and production time, production rate, yield, fuel consumption rate, fuel demand, fuel cost, energy efficiency, physicochemical and sensory parameters. The method used in this research is an experimental method with the object of research namely coconut sap. Coconut sap used from coconut plantations in Gandatapa Village. From the data analysis carried out, the results showed that the sap cooked with a pressurized LPG stove had a higher energy efficiency (43.29%) compared to the sawdust-fueled stove (13.83%), but in terms of the quality produced using the stove LPG NPSO and furnace can produce granulated sugar with quality standards according to SNI 01-3743-1995.

Abstract

Drying of grain is a process to reduce the water content. One of the obstacles in the drying process is the weather factor. The use of a rotary dryer with LPG gas fuel can be used as an alternative to dry grain. The purpose of this study was to determine the performance of the rotary dryer in grain drying including the optimum machine capacity, reduction in the moisture content of the material, drying energy, drying rate, and drying efficiency. The research method used is the experimental method. The condition of the grain moisture content tested was water content between 18%-22% and thermostat temperature between 50°C-60°C (treatment 1), moisture content between 23%-27%, and thermostat temperature between 60°C-70° C (treatment 2) with a total mass of 500 kg of grain. The results showed that the rotary dryer machine can be used to dry grain efficiently. The rotary dryer machine produces an average optimum capacity of 104.02 kg/hour in treatment 1 and 111.90 kg/hour in treatment 2, the decrease in water content in treatment 1 is 5.92% and in treatment 2 is 8.65%, drying energy in average 188.453 .1 kJ in treatment 1 and 162.862.7 kJ in treatment 2, Drying rate on average 2.71 % db/hour in treatment 1 and 4.47 % db/hour in treatment 2, Drying efficiency on average 32.67% in treatment 1 and 50.92 % in treatment 2.
