Case study and design the stirrer machine from solar energy for sugar jaggery

Abstract

The purpose of this research was for study and design of the stirring machine for jaggery from solar energy. By comparing the efficiency of Stirring process between machine from solar energy and manpower.

The stirring machine is assembled from 60-watt DC motor by Use a 10 amp MPPT Charger controller as a device that charges the electricity received from solar panels to charge the battery 12 volt 45 amp device is a device used to store electrical charges that can produce electricity to use immediately on a day without sunlight.

From the experiment, ii was found the jaggery was used 18 liter per cycle. When comparing production time from labor, taking 1-2 labors rotation, time using 60 minutes. The Stirling cycle of labor is 40 revolution per minute.

When using the sugar stirring machine for 35 minutes, the propeller revolving cycle is at 100 revolutions per minute. When comparing both stirring forms Mechanical agitation causes a time difference in comparison to 25-minute labor, which can be used to process various processes. To continue production When comparing the duration of 1 day, there will be production 3 times a day which will yield 54 liters per day. The labor of the people takes the time to stir the palm sugar in a total of 180 minutes per day. It takes a total of 105 minutes to stir per day when compared between labor and machinery. The use of machinery saves time than manual labor by 75 minutes per day, which is 58% faster than before. However, using machinery to replace labor can reduce labor fatigue. And can speed up the process after agitation.
