“…Water vapor on the surface of the grain will quickly be removed at high airflows, thereby preventing the water vapor from becoming saturated on the surface of the grain. Drying of coffee beans from the initial moisture content of 42% to 12% using a forced convection system at a velocity of 4.03 m/s takes about 3 hours [10].…”

Green coffee beans to be stored for transportation must meet storage quality standards, especially the maximum moisture content of 12.5%, so the drying process must be carried out to achieve quality standards, but still economical. The study aims to obtain optimum operating conditions on the drying of Arabica-type coffee beans using a fluidized bed dryer assisted by zeolite adsorbents in a separated fluidized bed prior to heating, as well as calculating the energy consumption of blowers and air heater. The operating conditions were varied, namely air flow rate of 1.79 – 2.29 m/s, air temperature of 45 o C, 50 o C, and 55 o C, zeolite adsorbent mass of 150 g, 175 g, and 200 g. The coffee beans quality tests carried out were the moisture, carbohydrates, protein content, and the visual appearance of the beans. The results show that the optimum drying process of coffee beans resulting a minimum protein and carbohydrate damage are the air velocity of 2.1 m/s, air temperature of 55°C, drying time of 240 minutes, and zeolite adsorbent mass of 150 grams, with energy consumption of 5.02 KWH (equivalent to 180 MJ/T). The addition of zeolite as much as 150 grams, 175 grams, and 200 grams as adsorbent was able to reduce the relative humidity (RH) of air by 16.65%, 18.60%, and 21.17% respectively. The drying rate of coffee beans is mainly influenced by air temperature (more predominantly) than the adsorption of air humidity by zeolite.

“…Therefore, it would be better if the company invests in a drying machine to reduce its dependence on climate conditions. Sun drying is done until the bean moisture reaches 42%, which takes approximately 3 days, and then followed by the use of a drying machine with 20-45 kilograms capacity and 3 hours of drying [18]. The temperature is also controlled at 60 o C to reach the expected moisture content of 11-12% and to maintain the quality.…”

The rapid competition between business and sustainability policy has encouraged the coffee industry in Indonesia to make their business more environmentally friendly. However, this initiative has yet to be fully underway. Several inefficiencies still prevail in Arabica coffee production sites, such as product defects in inventory, the inefficiency of production machine performance, and dependence on manpower that can increase the production and inventory costs. Therefore, the Arabica coffee agroindustry needs to improve its performance by addressing these issues in production activity using the lean manufacturing approach. Several tools proven influential to reduce waste in the agroindustry are Value Stream Mapping (VSM) and VALSAT. VSM could document the entire mapping of material and information management, but cannot classify the time required to complete the whole process. VALSAT has several derivative tools, but polyacrylamide (PAM) and Supply Chain Response Matrix (SCRM) are mostly used in agroindustry to classify value-added time of processes and illustrate the supply chain cumulative inventory of a company. The result of this study shows that the Indonesian Arabica coffee industry could reduce its cycle time by 57%, lead time by 63%, and changeover time by 50%. In addition, the recommendations result in the involvement of only 2 people during the drying process and eliminate the non-value-added time, while improving the overall production efficiency and capacity.

“…Penanganan pascapanen yang tidak baik akan menyebabkan terjadinya kehilangan hasil, baik bobot maupun kualitas produk yang dihasilkan, terutama untuk panen musim hujan (Firmansyah, et al, 2007). Sebagai contoh, salah satu penanganan pasca panen yang sangat dibutuhkan petani kopi adalah pengeringan (Sary, 2016).…”

Innovation of Coffee Postharvest Technology Machines as Campus Intellectual Business Products Lhokseumawe State PolytechnicAbstract. The growth of the area of coffee plantations continues to increase every year needs to be supported by the readiness of postharvest technology that is suitable to be able to produce quality coffee beans. The Lhokseumawe State Polytechnic has taken the opportunity to form a business unit for the production of appropriate the technology of the postharvest coffee machine, through a service program with the scheme of the Campus Intellectual Product Business Development Program. The center for production of machinery for appropriate technology for postharvest coffee The Lhokseumawe State Polytechnic aims to increase the productivity of coffee farmers through the mechanization of the coffee postharvest process by innovating appropriate technology technologies for coffee postharvest. Besides that to support campus independence through the business of producing coffee postharvest machines. The method of implementing activities starts from machine design, provision of raw materials, production processes, to product marketing. From the results of the activity has been formed production centers of appropriate technology for postharvest coffee machines. The center for production of machinery appropriate technology postharvest coffee has made innovations in coffee postharvest technology machines. Innovative products from the machine production center for appropriate technology for postharvest coffee include mobile pulper machines, coffee bean washing machines, mobile huller machines and multi-functional hullers, coffee bean sorting machines, and vibrating systems. These machines have advantages of construction and mobilization compared to products that have been circulating in the market so far. Product marketing has been done through a showroom as a place to showcase products, sales websites, and online stores.Keywords: innovation, postharvest technology, coffee, campus intellectual products.Abstrak. Pertumbuhan luas perkebunan kopi terus meningkat setiap tahun perlu didukung dengan kesiapan teknologi pascapanen yang cocok untuk dapat menghasilkan biji kopi bermutu. Politeknik Negeri Lhokseumawe telah mengambil peluang tersebut dengan membentuk unit usaha teknologi tepat guna pascapanen kopi, melalui program pengabdian dengan skim Program Pengembangan Usaha Produk Intelektual Kampus (PPUPIK). Kegiatan PPUPIK ini bertujuan menunjang kemandirian kampus melalui usaha produksi mesin-mesin pascapanen kopi melalui inovasi dan produksi mesin-mesin TTG pascapanen kopi. Kegiatan ini pada akhirnya akan meningkatkan produktifitas petani kopi melalui mekanisasi proses pascapanen kopi yang baik. Metode kegiatan PPUPIK terbagi dalam tiga tahapan, yaitu tahapan produksi, pemasaran dan pendirian unit usaha. Tahapan produksi dimulai dari design mesin, penyediaan bahan baku, proses produksi, sampai pemasaran produk. Dari hasil kegiatan telah terbentuk unit usaha Pusat Produksi Mesin-mesin Teknologi Tepat Guna Pascapanen Kopi. Unit usaha ini telah melakukan inovasi mesin teknologi pascapanen kopi. Produk inovasi dari Pusat Produksi Mesin-mesin Teknologi Tepat Guna Pascapanen Kopi antara lain mesin pulper mobile, mesin pencuci biji kopi, mesin huller mobile dan huller multi fungsi, dan mesin sortasi biji kopi sistem getar. Mesin-mesin TTG tersebut mempunyai keunggulan dari konstruksi dan mobilisasi dibandingkan produk yang telah beredar dipasaran selama ini. Pemasaran produk telah dilakukan melalui showroom sebagai tempat lokasi pamer produk, website penjualan, dan toko online.Kata kunci: inovasi, teknologi pascapanen, kopi, produk intelektual kampus.
