Komoditi pertanian merupakan produk yang sangat mudah untuk rusak bila disimpan pada kondisi yang tidak sesuai. Untuk menyimpan produk pertanian, pada umumnya dilakukan didalam ruang berpendingin, yang pada umumnya menggunakan thermostat sebagai pengatur suhu. Kelemahan yang paling umum ditemukan pada ruang penyimpanan produk pertanian berpendingin adalah besarnya rentang fluktuasi suhu di dalam ruang penyimpanan. Hal ini disebabkan penggunaan thermostat sebagai pengatur suhu ruang pendingin, dimana thermostat memiliki toleransi suhu yang cukup besar yaitu 3 oC sampai 5oC. Dengan demikian apabila suhu ruang pemnyimpanan yang diinginkan adalah 0 oC sampai 10 oC, maka suhu ruang pendingin sebenarnya berkisar antara -3 oC sampai 13 oC. Hal ini yang menyebabkan walaupun hasil produk pertanian sudah disimpan dalam ruang berpendingin, tetapi masih mudah rusak, karena suhu pada ruang pendingin tidak sesuai dengan suhu penyimpanan yang ideal. Pada penelitian ini telah dihasilkan sensor suhu yang lebih baik, menggunakan dioda yang mempunyai toleransi suhu lebih kecil dari thermostat. Dioda merupakan suatu komponen elektronik yang dapat dipengaruhi oleh perubahan suhu sebesar 0.2 oC . Sistem kontrol elektris yang digunakan dapat mengatur suhu ruang pendingin dengan toleransi kesalahan kurang dari 1 oC. Pada hasil pengujian diperoleh rentang kerja sensor dan sistem kontrol adalah 6 oC hingga 26 oC dengan error suhu 0.75 oC

IKM ”Simpati” telah beroperasi selama tiga bulan. Selama waktu tersebut seluruh biaya operasi disubsidi dari anggaran bantuan peralatan, dan hasil operasi seluruhnya diserap oleh pabrik makanan Unibis di medan. Namun Saat ini kondisi peralatan pengolahan coklat di IKM tersebut tidak lagi beroperasi. Hal ini disebabkan untuk mengoperasikan peralatan tersebut dibutuhkan infrastruktur dan biaya operasional yang cukup tinggi. Agar seluruh alat tersebut dapat beroperasional, maka setidaknya dibutuhkan daya Listrik sebesar 6500 watt – 7500 watt dengan biaya operasional 2 -3 juta rupiah perbulan. Biaya ini seharusnya dapat ditutupi oleh penjualan hasil produksi, namun rendahnya kapasitas kerja peralatan yang dihibahkan tersebut membuat operasi seluruh peralatan ini tidak ekonomis.Dari seluruh peralatan pengolahan kakao yang ada di IKM Simpati, kapasitas alat yang satu dengan yang lainnya tidak seragam. Pada alat alat seperti Alat Pemasta, Alat Pengempa, Alat Grinding/Kounching dan Alat pengayak kapasitas kerja alat hanya 600 – 1200gr/jam. Sedangkan pada peralatan lainnya, kapasitas kerja alat bervariasi antara 28 – 150 kg/jam. Dengan demikian maka akan terjadi ”Bottle Neck” (penyumbatan) pada alat-alat produksi dengan kapasitas kecil. Penyumbatan ini akan mengakibatkan bertumpuknya bahan baku pada fase tertentu dalam alur produksi sehingga waktu operasional alat bertambah dan mengakibatkan biaya produksi tidak ekonomis lagi. Untuk itu maka seluruh perlatan pengolahan kakao harus mempunyai kapasitas kerja yang seragam. Bagi peralatan dengan kapasitas kecil, maka jumlah alat harus ditambah atau alat diganti dengan kapasitas kerja yang lebih besar. Sebagai acuan kapasitas kerja yang digunakan adalah alat pengering dengan kapasitas kerja 1.5ton/hari atau 62.5kg/jam.

Testing the chemical components of coffee beans has so far been carried out conventionally with laboratory analysis which requires a long time and is expensive. Technological advances allow testing of chemical components to be carried out quickly and accurately using the NIRS (Near Infra Red Spectroscopy) method. This research aims to develop a prediction model for caffeine and protein in Solok Radjo coffee beans using the NIRS method. Solok Radjo coffee is a type of Arabica with specialty grade because of its very strong character, aroma and taste. A total of 30 samples with a weight of 6 g per sample were used in this study. This research uses NIRS Type FT-IR IPTEK T-1516 with a wavelength of 1000 - 2500 nm. The partial least squares (PLS) method was used to process the data with several SNV, MN, and MSC pretreatments to improve the model. The research results show that caffeine is found at wavelengths of 1456 - 1475 nm, 1937 - 1974 nm. Proteins 1455 - 1475 nm, and 1935 - 1974 nm. MSC pretreatment is able to improve PLS performance results. Caffeine calibration values are R2 = 0.996 and SEC = 0.002%, validation values R2 = 0.989, SEP = 0.002%, and RPD 11.869 while protein calibration R2 = 0.999 and SEC = 0.004%, Validation values R2 = 0.999, SEP = 0.010%, and RPD 19,943. NIRS can be used to predict the chemical components of Solok Radjo coffee non-destructively using the PLS method. Key work: Caffeine, NIRS, PLS, predict, protein

Crude palm oil (CPO) is a raw material for making cooking oil that comes from palm oil, which is greatly influenced by the quality of oil palm fresh fruit bunches (FFB). Oil and carotene content in the FFB influence the quality of palm oil. The oil content is usually determined using a chemical method (Soxhlet extraction) which is time consuming and destructive. This research aimed to predict the oil and carotene content contained in oil palm FFB using partial least square (PLS). In this research, the sample used was the Tenera variety with a maturity of 140-160 day after anthesis (DAA) and 200-220 DAA. The nondestructive method involves recording images using an optical camera, which produces RGB and L*a*b* values. Results showed that PLS predicts the relationship between optical properties and oil and carotene content in palm oil. Non-destructive prediction results using PLS provided consistently correlation of L*a*b* values with estimated oil and carotene content in the FFB. Keywords: Non-destructive, Optical properties, Fresh fruit bunch, Oil palm.
