The effect of the percentage of alaban waste and rice husk waste with tapioca adhesive on the physical properties

Abstract

Tapuk Village, Limpasu District, Hulu Sungai Tengah Regency is one of the processing centers for alaban wood charcoal in South Kalimantan. The alaban wood charcoal produced by Tapuk Village consists of several grades, namely: grade A, grade B, Grade C, and Grade D. Grade D charcoal is small pieces of charcoal which are leftovers from large charcoal, often called alaban wood charcoal waste. Around Tapuk Village, there are also many residents’ rice fields, where almost all year round there are piles of rice husks that are not used by the residents. The benefits of alaban wood charcoal and rice husk waste can be increased by making it into briquettes. The percentage of briquettes waste of alaban wood charcoal and rice husks, namely 100%: 0%, 90%: 10%, 80%: 20%, 70%: 30%, 60%: 40%, 50%: 50%, 40%: 60%, 30%: 70%, 20%: 80%, 10%: 90%, and 0%: 100%. Briquettes also use 5% tapioca starch adhesive. The briquettes are then tested for their physical properties. From testing and analysis, it is known that the moisture content, ash content, and volatile matter content increased along with the increase in the percentage of rice husks. The content of bound carbon (fixed carbon) and heating value decreased along with the increase in the percentage of rice husks.

Production of bio-briquettes from pineapple peels and sewage sludge as an alternative renewable energy

“…Correspondingly, tapioca starch adhesive carried higher carbon content than other adhesive types. This was due to the high carbon content of tapioca starch, 85.2% [38].…”

Effect of Variation of Mixture (Wood Gelam+Rice Husk) on Bio-Pellet on the Value of Temperature, Rate and Pressure of Combustion

“…Pellet raw materials can be taken from useless materials such as gelam waste and rice husk waste which are widely available around us. Gelam wood has a calorific value of 4100 cal/g [28] and rice husks of 3300 cal/g [32]. The addition of the percentage of gelam does not increase the combustion temperature as well as the addition of the percentage of rice husks; this is very beneficial when considering the lower calorific value of rice husks.…”
