Abstract

In 2015, the area of oil palm plantations in Indonesia had reached 10,701,436 ha, with details of the people's oil palm plantation 4,810,271 ha, state-owned oil palm plantations 704,094 ha and private oil palm plantations 5,207,071 ha. A ton base of fresh palm oil fruit bunches will produce 20% - 23% CPO; 5% - 7% PKO and the rest in the form of solid waste, namely 20% - 23% oil palm empty bunches; 10% - 12% oil palm fruit fiber and 7% - 9% oil palm shells.In the implementation of this study, oil palm shell charcoal was made by treating palm oil shells. From the treatment of oil palm shell roasting, the average yield was 38.20% (the last temperature of roasting 348 0 C, when the palm shells being roasted were no longer smoke).From the results of the chromatogram analysis of GC - MS, oil palm shell charcoal is known as 25 organic compounds with the dominant composition being cyclopropyl with a concentration of 14.87%; acetic acid with a concentration of 17.01%; benzenesulfonic acid with a concentration of 12.11%; benzene with a concentration of 7.3% and phenol with a concentration of 15.59%.The characterization of the composition of the organic palm shell charcoal organic compounds needs to be done in order to about the development of the use of oil palm shell charcoal as an auxiliary material to increase plant fertility.

Abstract

Penelitian ini bertujuan untuk mengetahui performansi pengeringan biji kakao fermentasi dengan mengkondisikan udara pengering sehingga memiliki kelembaban yang lebih rendah dan suhu yang lebih tinggi daripada lingkungan. Penelitian ini menggunakan pompa kalor, kolektor surya, evaporator dan kondensor. Pengeringan berlangsung di posisi 3,36°LU - 98.4°BT, pada ketinggian 200 meter di atas permukaan laut dan waktu meridian (GMT + 7), selama tiga (3) hari dengan tiga kali pengulangan. Selama pengeringan, intensitas radiasi berada pada kisaran 20-803 Watt/m2 dan suhu ruang pengering dalam kisaran 32-48°C dan 35-80%RH. Hasil percobaan menunjukkan bahwa efisiensi termal rata-rata solar kolektor adalah 40-51%. Koefisien kinerja (COP) dan total kinerja pompa kalor, berturut-turut adalah 3,9 dan 9,3. Laju pengeringan, laju penguapan air spesifik dan konsumsi energi spesifik berturut-turut adalah 0,0481 kg/jam, 0,294 kg/kWh dan 6,12 MJ/kg. Pengeringan surya dibantu pompa kalor memberikan waktu pengeringan lebih pendek (rata-rata 24 jam) daripada penjemuran langsung (rata-rata 40 jam atau 5 hari).Kata kunci: pengeringan, tenaga surya, pompa kalor, performansi, mutu biji kakao ABSTRACTThis research aims to find out the performance of drying of fermented cocoa beans by conditioning the dryer air so that it has lower humidity and higher temperature than the ambient condition. This research uses heat pump, solar collector, evaporator and condenser. Drying takes  at position 3.36 oLU - 98.4 oBT, at an altitude of 200 meters above sea level and meridian time (GMT + 7), for three (3) days with three repetitions. During drying, the radiation intensity is in the range of 20-803 Watts / m2 and the drying room temperature in the range of 32-48 oC and 35-80% RH. The experimental results show that the average thermal efficiency of collector solar is 40-51%. The performance coefficients (COP) and total heat pump performance, respectively, are 3.9 and 9.3. Drying rate, specific water evaporation rate and specific energy consumption are 0.0481 kg / hour, 0.294 kg / kWh and 6.12 MJ / kg, respectively. The solar drying assisted heat pump gives shorter drying time (24 hours on average) than direct drying (average 40 hours or 5 days).
