Tujuan penelitian ini adalah untuk menganalisis kelayakan rencana pendirian usaha pengolahan tempurung kelapa menjadi asap cair dan briket di Kecamatan Pengabuan, Kabupaten Tanjung Jabung Barat, Provinsi Jambi Jambi yang dilihat dari aspek teknis, pasar, dan finansial. Ketersediaan bahan baku tempurung kelapa sebesar 1.500 ton/tahun. Jika satu kali produksi memerlukan 6,25 ton tempurung kelapa, maka dapat menghasilkan 3.750 liter asap cair, dan 1.912 kg briket. Lokasi yang dipilih untuk usaha ini adalah Desa Parit Pudin dengan tata letak pabrik menggunakan tipe produk. Harga jual untuk asap cair yaitu Rp22.000/liter dan briket yaitu Rp12.196/kg. Target pasar untuk asap cair grade 3 adalah industri pengolahan lateks, sedangkan target pasar untuk briket adalah negara yang mempunyai 4 musim. Kelayakan aspek finansial meliputi NPV lebih besar dari nol yaitu Rp38.511.979.874, IRR lebih besar dari MARR 7% yaitu 85,38%, payback period selama 1,48 tahun, dan net B/C yaitu 2,43. Keseluruhan kriteria kelayakan secara teknis, pasar dan finansial didapatkan bahwa usaha asap cair dan briket dari tempurung kelapa layak didirikan.

Tea (Camellia sinensis) is widely grown for its leave sand is commercialized as black tea. Product diversification and value addition are currently are of great interest. This study provides data on the physicochemical properties of tea seed oil from Kayu Aro, Jambi Province. Extraction using-hexane was employed to obtain tea seed oil followed by physical-chemical analysis to assess its properties. Physicochemical properties, namely oil yield, density, refractive index, viscosity, turbidity, color, and melting point, as well as free fatty acid, iodine value, peroxide value, and saponification were determined. The oil yield is up to 14% (dB), density is 882.5±5.5kg/m3, refractive index is 1.48±0.20, viscosity is 64.1±0.2 Pa.s, turbidity is 0.88, color 47.0 (L),34.6 (C) and 95.3 (h) as well as free fatty acid 0.39-0.92%, iodine value 29.63-30.87gI2/100g, peroxide value 0.019-0.417 meq O2/100g, and saponification 127.721-168.382. Tea seed oil is stable and can be a potential source of edible and non-edible applications, such as natural nutraceutical,  pharmaceutical, and cosmetic products

Areca nut coir contains several chemical compounds, i.e., cellulose (34,18%), hemicellulose (20.83%), and lignin (31.6%). These chemical compounds are a source of carbon in the manufacture of activated charcoal or adsorbents and coconut coir is a material containing lignicellulose which can be used as a substitute for fuel. One way to use areca nut and coconut coir is to make biobriquettes. Processing of areca and coconut coir into biobriquettes deals with numerous production factors, starting from additional materials, labor, production equipment, and other materials. Processing costs are conducted to obtain higher prices and higher profits than without a production process, so value added analysis is needed. The purpose of this research is to find out the added value generated from processing areca nut shells and coconut coir into biobriquettes. Data were obtained from primary and secondary data. The methods used in this research are descriptive and quantitative methods. Based on the results of the research, processing of areca shell charcoal and coconut coir into biobriquettes starts from ordering raw materials, maintenance and storage of raw materials. The production process is conducted by weighing the raw materials, carbonizing, milling, sieving, mixing charcoal flour with tapioca flour, moulding, drying and packaging. and added value analysis shows that the business plan for processing areca shell charcoal and coconut coir into biobriquettes obtains an added value of Rp. 3,077/kg of raw materials. A large added value of zero (Rp. 3,077> 0) means that the utilization of areca nut shells and coconut husks into biobriquettes generates added value.
