Abstract

Currently the preservation of fruit and vegetables in Indonesia is still done with traditional. Most post-harvest handling of fruits and vegetables in Indonesia directly sold into the market. So at harvest, the quantity of the commodity is abundant and when the time of harvest finished exhausted and rare commodity. In the fruit and vegetable preservation, temperature and relative humidity are two control variables that influence each other. Where the increase and decrease in temperature will result in changes in relative humidity. In this research carried out two variations control the digital control and control scheduling to determine the characteristics of the relationship of temperature and relative humidity . Results from both trials showed that the variation of the control of digital control has a good quick peak time to reach the set point temperature and humidity. While scheduling control humidity rise with the increase in temperature.     

Keywords : Temperature, Relative Humidity, Fruits, Vegetables, preservation.

 

Abstrak—Saat ini proses pengawetan buah dan sayuran di Indonesia masih dilakukan dengan cara tradisional. Banyak buah dan sayuran pasca panen langsung dijual ke pasar. Sehingga pada saat panen, kuantitas komoditi tersebut melimpah dan disaat waktu panen selesai komoditi tersebut habis dan langka. Pada pengawetan buah dan sayuran, suhu dan kelembaban relatif merupakan dua variabel kontrol yang saling mempengaruhi. Dimana kenaikan dan penurunan suhu akan berakibat pada perubahan kelembaban relatif. Pada penelitian kali ini dilakukan dua variasi kontrol yaitu kontrol digital dan kontrol scheduling untuk mengetahui karakteristik hubungan suhu dan kelembaban relatif. Hasil dari uji kedua variasi kontrol tersebut didapatkan bahwa kontrol digital memiliki waktu puncak yang cepat baik untuk mencapai set point suhu dan kelembaban. Sedangkan kontrol scheduling kenaikan kelembaban mengikuti kenaikan suhu.
    
Kata Kunci : Suhu, Kelembaban Relatif, Buah, Sayuran, Pengawetan
