Rancang Bangun Mesin Pengurai Sabut Kelapa Menjadi Cocopeat menggunakan Mata Pisau Tipe Gunting Dengan Kapasitas 50kg/jam

Bengkalis Island is one of the regions in Riau Province known as a coconutproducing area. The high level of coconut farming activities in this region results in an abundance of coconut husk waste that has not been optimally utilized. In fact,coconut husks can be processed into valuable products such as cocopeat and cocofiber, which are widely used as growing media and raw materials for the handicraft industry. Based on this potential, this research aims to design and develop a coconut husk decorticating machine with a target capacity of 50 kg/hour to support the utilization of coconut husk waste by local communities, especially farmers in Bengkalis Island. The machine is designed using a scissor-type cutting blade system, consisting of a rotating blade and a stationary blade to produce finely shredded and separated material. The machine is powered by a 7 HP diesel engine (dompeng) operating at a high rotation speed of 2400 rpm. Test results show that the machine is capable of processing 28 kg of dried coconut husk per hour, producing 17 kg of cocopeat and 6.5 kg of cocofiber, while the remaining 4.5 kg is lost as fine fibers due to the absence of a dust control system. The resulting cocopeat has a fine particle size of approximately 2 mm mesh, which meets the standard for horticultural growing media. Based on performance tests, the machine has proven to operate according to its design objectives, although the actual capacity is still below the initial target. It is expected that this tool can serve as an appropriate technology solution for the people of Bengkalis Island to increase the added value of coconut husk waste and support the development of a sustainable agricultural sector.
