Efforts to maximize the utilization of coconut derivative products are still being carried out in coconut production centers. North Sulawesi as one of the highest coconut-producing regions in Indonesia is still trying to increase the value of existing coconut products. One of the problems faced in increasing the value of coconuts is the decreasing number of workers who climb and peel coconuts. Coconut coir as a very significant part of the amount in one fruit still needs attention so that its value can be increased. Coconut coir has the potential to be utilized but requires processing equipment, which can decompose coconut coir into fiber (coco fiber) and dust (cocopeat). The problem is that decomposers are relatively difficult to obtain in this area, and if they are available, they have to be imported from other islands and they are expensive. For this reason, this research was made, namely to make and test the performance of coconut coir processing equipment. The research method was carried out experimentally, and the data obtained were analyzed descriptively. Experiments were carried out using the engine rotation speed: 500 rpm, 600 rpm, and 700 rpm. The raw material for coconut fiber used was 10 kg with three repetitions. From the results of the study, it was found that the best results were at a speed of 500 rpm which was able to produce the highest yield of 90.9 percent of total cocopeat and coco fiber, while at speeds above 500 rpm, namely 600 rpm and 700 rpm, the higher the coir material that became granules dust. The highest decomposition yield of coir into coco fiber was at 500 rpm, namely 95.68 kg/hour or as much as 765.44 kg/day (note: 1 day = 8 hours). To increase comfort, further research can be directed at ergonomic testing to increase the comfort and safety of using the tool. Keywords: Coconut husk, cocopeat, coco fiber, performance test, decomposition machine. Abstrak Upaya pemanfaatan maksimal dari produk turunan kelapa masih terus dilakukan di daerah sentra produksi kelapa. Sulawesi Utara sebagai salah satu daerah penghasil kelapa tertinggi di Indonesia masih terus berupaya untuk meningkatkan nilai dari produk kelapa yang sudah ada. Salah satu permasalahan yang dihadapi dalam peningkatan nilai kelapa adalah semakin berkurangnya tenaga kerja yang pemanjat dan pengupas kelapa. Sabut kelapa sebagai bagian yang sangat signifikan jumlahnya dalam satu buah, masih perlu perhatian untuk dapat ditingkatkan nilainya. Sabut kelapa berpotensi untuk dimanfaatkan akan tetapi perlu alat pengolah, yang dapat menguraikan sabut kelapa menjadi serat (cocofiber) dan debu (cocopeat). Permasalahannya adalah alat pengurai relatif sulit didapat di daerah ini, dan bila ada harus didatangkan dari pulau lain serta harganya mahal. Untuk itulah penelitian ini dibuat yaitu membuat dan menguji kinerja alat pengolahan sabut kelapa. Metode penelitian dilakukan secara eksperimental, data yang didapatkan di lakukan analisis secara deskriptif. Percobaan dilakukan menggunakan kecepatan perputaran mesin: 500 rpm, 600 rpm, dan 700 rpm. Bahan baku sabut kelapa yang digunakan sebanyak 10 kg dengan tiga kali ulangan. Dari hasil penelitian didapati bahwa hasil terbaik, adalah pada kecepatan 500 rpm yang mampu menghasilkan rendemen tertinggi sebesar 90,9 persen total cocopeat dan cocofiber, sedangkan pada kecepatan di atas 500 rpm, yakni 600 rpm dan 700 rpm, semakin tinggi bahan sabut yang menjadi butiran debu. Hasil penguraian tertinggi sabut menjadi serat sabut kelapa pada kecepatan 500 rpm, yaitu 95,68 kg/jam atau sebanyak 765,44 kg/hari (catatan:1 hari= 8 jam). Untuk meningkatkan kenyamanan, penelitian lebih lanjut dapat di arahkan pada pengujian ergonomis untuk meningkatkan kenyamanan dan keamanan penggunaan alat.

The coconut husk is the outermost part of the coconut fruit that covers the coconut shell whereas one coconut contains 35% husk. In several areas, including in North Sulawesi, a lot of coconut husk is still being thrown away or left in the garden. Coconut husk has a potentially utilized energy capacity. For this reason, the idea arose to make a stove for energy utilization from coconut husk waste with a gasification system. The purpose of this study was to design and technically test a household-scale coconut husk stove with a gasification system. The research method was carried out by design and experimental testing, then the resulting data were analyzed descriptively. In this study, two types of stoves were designed and manufactured which were practical for application on a household scale using a gasification system made from coconut coir. The first stove that uses an air blower can reach a temperature of 740 ℃ and is tested with 1.5 liters of water, so the water can boil for 9 minutes. The second stove, which does not use an air blower, can boil 1.5 liters of water for 11 minutes at a temperature of 608℃. Both stoves have a waiting time to produce gas that is not much different, which is about 3 minutes with an initial fuel mass of 300 g. The results of economic calculations show that the cost of making this stove is relatively cheap and easy to maintain. However, the raw material for coconut coir runs out quickly and requires several replenishments of raw materials. Keywords: Stove, household scale, gasification, coconut husk. Abstrak Sabut kelapa merupakan bagian terluar buah kelapa yang membungkus tempurung kelapa dimana dalam satu butir buah kelapa mengandung 35% sabut. Di beberapa daerah termasuk di Sulawesi Utara, sabut kelapa masih banyak yang dibuang atau dibiarkan saja di kebun. Sabut kelapa mempunyai kapasitas energi yang potensial dimanfaatkan. Untuk itulah timbul ide untuk membuat kompor sebagai pengganti kompor untuk pemanfaatan energi dari limbah sabut kelapa ini dengan sistem gasifikasi. Tujuan penelitian ini adalah membuat rancangan dan uji teknis kompor sabut kelapa skala rumah tangga dengan sistem gasifikasi. Metode penelitian dilakukan dengan pembuatan dan uji teknis alat secara eksperimental, kemudian data yang dihasilkan di analisis secara deskriptif. Dalam penelitian ini di buat dua tipe kompor yang diharapkan dapat diaplikasikan pada skala rumah tangga dengan menggunakan sistem gasifikasi berbahan baku sabut kelapa. Kompor yang pertama yang menggunakan penghembus udara dapat mencapai suhu 740℃ dan uji coba dengan air 1,5 liter, maka air tersebut dapat mendidih selama 9 menit. Kompor yang kedua, yang tidak menggunakan penghembus udara dapat mendidihkan air 1,5 liter selama 11 menit dengan suhu mencapai 608℃. Kedua kompor mempunyai waktu tunggu untuk menghasilkan gas tidak berbeda jauh, yaitu sekitar 3 menit dengan massa bahan bakar awal 300 g. Hasil perhitungan ekonomi menunjukkan bahwa biaya pembuatan kompor ini relatif murah dan mudah pemeliharaannya. Akan tetapi bahan baku sabut kelapa cepat habis dan memerlukan beberapa kali pengisian bahan bahan baku. Kata Kunci: Kompor, skala rumah tangga, gasifikasi, sabut kelapa.

Corn is still an important commodity for small farmer industries in Indonesia. However, one of the problems is the natural drying process with direct sunlight which is quite long and is often disturbed in the rainy season. Reaching 14% moisture content often takes up to 6-7 days so it is not efficient. This is because the direct drying temperature is relatively low, and when it rains it must be moved around, thus increasing labor costs. Several artificial dryers have been developed, but the price is relatively expensive so it is not affordable for small industrial scale. The purpose of this study was to design and evaluate a simple small-scale dome-type dryer. The results showed that the dryers that have been designed and made are quite practical and effective to use for small-scale farmers. Drying time from 35-40% water content to 13.5-14.5% within 2 days with an average drying temperature in the tool 40-56 oC.
