RANCANG BANGUN ALAT PENGONTROL SUHU PADA PROSES PENGOMPOSAN SAMPAH BERBASIS MIKROKONTROLER ATMEGA8
ABSTRACT: Compost is organic
materials like leaves, straws, reeds, grasses, and even the animal faces which
have experienced decomposition process by micro organism so can be used to
repair the nature of soils. The aims of this research are (1) Designing
Temperature Controller system by using LM35 temperature Censor with Atmega8
microcontroller, (2) Designing and constructing software using C language
program to control temperature automatically, (3) Testing temperature
controller device at composting machine. Research parameters include censor
calibrating, microcontroller testing, and whole device testing. The research
conduction got the result for temperature sensor 1, 2, 3, and 4 used LM35
censor at range 25oC – 70oC. Linear regression for censor 1: y = 0.098x + 2.059
determination coefficient score is 0,996. Linear regression for censor 2: y =
0.101x + 0.876 determination coefficient score is 0,995 Linear regression for
censor 3 and 4: y = 0.098x + 2.059 with determination coefficient = 0,996. From
the whole device testing, first step intake of temperature data, 30 minutes
interval for 3 days: deviation score 1st day = 0.98, 2nd day = 0.906, and 3rd
day = 0.937. Controlled temperature composting needs less time and produce less
stink than composting without temperature control.
