Abstract

Briquettes mixture of peat and charcoal leaf midrib palm oil is one of the alternative energy for replacing fossil fuel energy. It is environmentally friendly and abundant in Indonesia, mainly in South Kalimantan. In this study, the percentage of briquettes mixture of peat and charcoal leaf midrib of palm oil were 50%:50%, 60%:40%, 70%:30%, 80%:20% and 90%:10%, respectively. In addition, 1 gram of starch was added as an adhesive for every variation of briquettes mixture. In briquetting process, the pressures were 10 kg/cm2, 20 kg/cm2 and 30 kg/cm2. The combustion characteristics of  briquettes was tested, then it was compared by subbituminous coal briquettes. The results show, ignition delay of briquettes decrease by increasing additional percentage of peat, however extend the burning time of briquettes, consequently the burning rate decrease and the briquettes temperature becomes low. Briquetting pressure affects the combustion characteristics of briquettes. Ignition delay of briquettes decrease by the pressure. On the other hand, extend the burning time of briquettes and decrease the burning rate, however combustion temperatures of briquettes increases. The results also show a comparison of mixture briquettes peat and charcoal palm leaf midrib with subbituminus coal briquettes. The subbituminous coal briquettes produces higher combustion temperature, the longer combustion process and the lowest  combustion rate.

Abstract

South Kalimantan is one of the natural habitats of gelam wood. In South Kalimantan, gelam wood can grow well and fertile. This makes the availability of gelam wood abundant and can be used for various purposes, one of which can be used as raw material for wood pellets (biomass energy). Wood pellets made from gelam wood have not been widely studied, so it is necessary to know the effect of the size of gelam wood powder and the addition of the percentage of adhesive on the physical properties of gelam wood pellets. Wood pellets made from gelam were made using various sizes of powder (mesh) 40, 50, and 60 as well as using flour adhesive (percentage of adhesive 5%, 10%, and 15%). Gelam wood pellets were then tested for physical properties in order to determine their performance. From the research that has been carried out, it is found that the volatile matter content, ash content, and water content tend to increase with the smaller size of the gelam sawdust. Meanwhile, the calorific value and fixed carbon content have a tendency to decrease with the smaller size of the gelam sawdust. volatile matter content, ash content, and water content tend to increase as the percentage of adhesive is increased. Meanwhile, the calorific value and fixed carbon content tend to decrease with the increase in the percentage of the amount of adhesive.

Tujuan dari penelitian ini adalah untuk mengetahui pengaruh variasi ukuran mesh dan persentase perekat tapioka terhadap sifat fisik pellet kayu gelam. Metode yang digunakan adalah secara eksperimental. Pellet kayu gelam dibuat dengan menggunakan variasi ukuran serbuk (mesh) 40, 50, dan 60 serta menggunakan perekat tapioka dengan persentase perekat 5%, 10%, dan 15%. Pellet kayu gelam selanjutnya di lakukan pengujian di laboratorium Baristand Banjarbaru. Pellet kayu gelam diuji meliputi pengujian sifat fisik yang terdiri dari nilai kalor, kadar air, kadar abu, kadar zat-zat terbang (volatile matter), dan kadar karbon terikat (fixed carbon). Hasil pengujian menunjukkan pellet kayu mengalami peningkatan pada kadar air, kadar abu, dan kadar zat-zat terbang seiring semakin kecilnya ukuran serbuk (mesh) kayu gelam. Sedangkan kadar karbon terikat dan nilai kalor pellet kayu mengalami penurunan seiring dengan semakin kecilnya ukuran serbuk (mesh) kayu gelam. Sehingga dapat disimpulkan bahwa penambahan perekat tapioka mempengaruhi karakteristik sifat fisik pellet kayu, semakin tinggi persentase perekat maka kadar air, kadar zat-zat terbang, dan kadar abu semakin meningkat. Sementara itu, penambahan persentase perekat pada pellet kayu menyebabkan penurunan pada kadar karbon terikat dan nilai kalornya. AbstractUtilization of the potential of biomass found in South Kalimantan with abundant raw materials, one of which is gelam wood which can be used as boiler fuel for steam power plants to reduce the use of coal fossil fuels. Gelam wood is processed into wood pellets using tapioca flour adhesive. The gelam wood pellet then carried out tests in the form of testing physical properties which included water content, ash content, volatile matter content, fixed carbon content, and calorific value. Wood pellets made from gelam were made using various sizes of powder (mesh) 40, 50, and 60 as well as using tapioca adhesive (percentage of adhesive 5%, 10%, and 15%. The gelam wood pellets were then tested for physical properties to determine their performance. The test results showed that wood pellets increased in moisture content, ash content, and volatile matter content along with the smaller size of gelam wood powder (mesh). While the carbon content and calorific value of wood pellets decreased along with the smaller size of the gelam wood powder (mesh). The addition of tapioca adhesive characteristics affect the physical properties of wood pellets, the higher the percentage of adhesive, the water content, volatile matter content, and ash content increase.
