Abstract

This study was performed to evaluate the input-otput energy for oil palm production and to identify the possibility to save energy consumption for activities related to oil palm production. Observation was conducted at PTPN VII Farm Unit of Rejosari, South Lampung. The energy inputs included human power, fuel and electricity as well as indirect energy resulted from the use of farm machinery, fertilizer, and pesticide. Energy outputs to be considered were resulted from full fruit bunch (FFB) consisted of crude palm oil (CPO), palm kernel oil (PKO), fiber, shell, empty fruit bunch, and trunk. The study revealed that total energy input of 57,63 GJ.ha-1 was required in oil palm production. Maintenance of productive plant consumed the highest energy, that was 33,06 GJ.ha-1  or 57,37 % of the total energy input. Based on energy sources, fertilizer was the most important input for oil palm production, accounted for 31,22 GJ.ha-1  (51,18 % of total energy input). The study also concluded that oil palm production generated energy output of 339,14 GJ.ha-1 with energy rasio of 5,88, energy productivity of 0.258 kg FFB per MJ, energy intensity of 3,87 MJ per kg FFB, and net energy gain of 281,51 GJ.ha-1.ABSTRAKPenelitian ini bertujuan untuk menganalisis energi masukan-keluaran dan mengidentifikasi kemungkinan penghematan energi pada proses budidaya kelapa sawit. Penelitian dilakukan di PTPN VII Unit Usaha Rejosari, Lampung Selatan dengan mengamati semua energi yang digunakan dan dihasilkan. Energi masukan terdiri dari tenaga manusia, bahan bakar, energi tidak langsung dari pupuk, pestisida, dan alat-mesin pertanian. Energi keluaran berasal dari tandan buah segar (TBS) dengan komponen minyak sawit, minyak inti sawit, serat, cangkang, dan tandan kosong, serta pelepah. Hasil penelitian menunjukkan bahwa budidaya kelapa sawit memerlukan energi masukan sebesar 57,63 GJ.ha-1  dan menghasilkan energi 339,14 GJ.ha-1. Sebagian besar energi masukan adalah penggunaan pupuk yang mencapai 31,22 GJ.ha-1  (54,18 % dari total energi masukan). Berdasarkan tahapan budidaya, maka pemeliharaan tanaman produktif memerlukan energi yang paling besar yaitu 33,06 GJ.ha-1  (57,37 %). Budidaya kelapa sawit menghasilkan energi neto 281,51 GJ.ha-1 dengan rasio energi 5,88, produktivitas energi 0,258 kg TBS/MJ, dan intensitas energi 3,87 MJ/kg TBS.

Abstract

Oyster mushroom can grow properly at temperatures of 16–30 °C and relative humidity of 80–95%. Environment conditioning by spraying of water in mushroom house manually in the morning and evening as the temperature and humidity controling is less effective and highly bothersome. Using of technology can controlling temperature and humidity in a mushroom house automatically.  This research aims to design an automatic control system to control temperature and humidity in oyster mushroom house. Research is located at an altitude of 125 meters above sea level. Automatic control system with a setting point temperature of 25 – 30 °C and humidity of 80 – 95% was tested at mushroom house with dimensions of 4 × 2 × 2 m with a capacity of 600 baglog mushrooms.  The results show that the performance of daily temperature and humidity without control is respectively 24.10 to 35.19 °C and 64.28 to 99.90%. While the temperature and humidity with the control system are 25.10 to 30.09 °C and 80.84 to 99.90%, respectively.
