Abstract

Kemiri (Aleurites moluccana Willd.) merupakan salah satu komoditi Hasil Hutan Bukan Kayu (HHBK) di Kecamatan Batulanteh, Sumbawa, Nusa Tenggara Barat, dengan luas lahan pada tahun 2015 sebesar 595,7 ha dan total produksi sebesar 285,17 ton (BPS, 2017). Penanganan pasca panen dan pengolahan kemiri masih dilakukan secara tradisional yaitu dimulai dari pengeringan dan pemecahan kemiri. Proses pengeringan biji kemiri dengan menggunakan sinar matahari langsung membutuhkan waktu 1-7 hari, sedangkan kapasitas pengupasan kulit secara tradisional sebesar 5-6 kg per hari. Permintaan yang tinggi dengan produksi kemiri yang rendah mengakibatkan efisiensi usaha menjadi rendah. Sehingga dibutuhkan suatu alat yang mampu mengeringkan kemiri yaitu dengan Mesin Oven Kemiri Berbasis Solar Dryer (MASKIRI-BSD). MASKIRI-BSD menggunakan kolektor surya yang tersusun dari plat absorber berbentuk gelombang dengan tebal 0,4 mm dengan nilai konduktivitas (k) 11,2 W/m0. Selain itu menggunakan penutup kaca bening dengan tebal 3 mm dengan kemiringan kolektor 18o. Alat ini menggunakan rangka berupa aluminium hollow dan besi siku. MASKIRI-BSD dapat menghasilkan rata-rata T out sebesar 82.01oC dari T in sebesar 360C sehingga, pengeringan kemiri hanya berlangsung selama 1,5-2 hari, hal ini lebih efektif dan efisien dibandingkan dengan pengeringan tradisional. Penggunaan MASKIRI-BSD juga mempercepat tingkat titik impas yang diperoleh, yaitu hanya dalam waktu 3 jam atau 0,14 kali pengeringan, sehingga pengusaha lebih cepat mendapatkan laba.

Abstract

Indonesia one of the plants that leaves and seeds grow has many useful benefits for human life, namely candlenut. The post-harvest handling of candlenut at the farm level it is generally still done traditionally where candlenut is drying on the floor or by direct exposure to solar radiation. They need approximately 7-9 days to get the appropriate drying results. Candlenut drying is influenced by the intensity of solar radiation on temperature and drying time according to the required hazelnut content. the dry hazelnut can use solar radiation power that is solar dryer. Absorbent plate is one component that is very important because it functions to absorb the intensity of solar radiation and convert it into heat energy and move it to the workpiece (candlenut) above it. In this study, testing was done on variations of the absorbent plates of zinc, aluminum and iron as well as variations in the thickness of the absorbent plates. Data collection starts at 09:00 until 15:00 WITA in sunny weather conditions. The results showed that the aluminum absorbent plate with a thickness of 0.04 mm was more effective and efficient in drying the candlenut to increase the productivity of the candlenut. The highest absorbent plate temperature and drying time were found on the aluminum absorbent plate with a thickness of 0.4 mm that is 72.36 oC and a drying time of 6 hours and meets the standard of moisture content of candlenut solution, which is 5.3%.

Abstract

Candlenut is a spice that is used as an ingredient in the manufacturing process of the food and cosmetic industry, the obstacles faced in breaking the candlenut shell are that the time and energy required is still too large so that the splitting of the candlenut shell is less efficient and there are still many farmers who still use traditional candlenut crackers. with a driving force in the form of human power. In addition, the results of the quality of the candlenut cracking are not good because there are still many broken hazelnut seeds after the process of breaking the candlenut shell. These constraints add to the time, cost and effort in the process of breaking candlenut manually. From some of the constraints that have been described, there is an idea to conduct research to find out how the rotation of the candlenut crusher influences the pressure according to the needs and optimizes the rotation variation of the candlenut crusher to produce whole candlenuts. The research method used is rotational variation (10 RPM, 20 RPM, and 27 RPM) to pressure 24.928 /????2, 21.952 /????2 and 19.286 /????2 with three treatments and each treatment combination was repeated three times. The parameters of this research are the percentage of whole, split, crushed and unbroken candlenut. The results of this study indicate that variations in rotation and pressure affect the percentage yield of candlenut seeds. The average value of the right rotation to break candlenut seeds with a beating pully A is 20 rpm with a pressure of 24.928 N/m2 to get an average of 60% intact, 20% halved, 0% crushed and 20% unbroken. At the right rotation of the pulley B, which is at 20 Rpm with a pressure of 21.952 N/m2, the average value of breaking is 60%, intact is 60%, split is 30%, destroyed is 0% and does not break is 10%. Meanwhile, at a pressure of 19.286 N/m2 for a rotation of 20 Rpm, the average value of broken, 50% intact, 0% halved, 20% crushed and 30% unbroken.
