Abstract: DELOS SANTOS, SIR MAURIS N., CIPRES, JOHANNA KRIS B., MOJICA, ERICK JOHN L. Charcoal Briquette (Fuel) Production from Cow Dung- Rice Hull Mixture and Coconut Husk. Applied Research Il. Cavite State University, Science High School. April 2005. Adviser: Dr. Lilibeth P. Novicio The study was conducted at the Forest Products Research and Development Institute at Los Bafios, Laguna. It aimed to recycle cow dung, rice hull, and coconut husk into briquettes for fuel, determine and evaluate the physical and chemical properties of briquettes produced from cow dung-rice hull mixtures and coconut husk, and determine the best treatment in producing charcoal briquettes from cow dung-rice hull mixture and coconut husk. The cow dung-rice hull mixture and coconut husk were mixed with cassava starch in the desired proportion of 9:1 (9 parts agro waste: 1 part cassava starch). The mixture was molded using the briquetting machine fabricated at the Forest Products Research and Development Institute at Los Bafios, Laguna. Different treatments were used: Treatment 0 (Control) commercial abaca charcoal briquettes, Treatment 1 (T)) 100% cow dung-rice hull mixture (200g cow dung-rice hull mixture), Treatment 2 (T2) 50% cow dung-rice hull mixture and 50% coconut husk (100g cow dung-rice hull mixture + 100g coconut husk), Treatment 3 (T3) 75% cow dung-rice hull mixture and 25% coconut husk (150g cow dung-rice hull mixture + 50g coconut husk), Treatment 4 (T4) 25% cow dung-rice hull mixture and 75% coconut husk (50g cow dung-rice hull mixture and 150g coconut husk) and Treatment 5 (T5) 100% coconut husk (200g coconut husk). Based on the results of this study, briquettes can be produced from cow dung, cow dung-rice hull mnistive and coconut husk, and coconut husk. Chemical properties of the briquettes such as moisture content, volatile combustible matter, ash content and fixed carbon were comparable to commercial briquettes. On the other hand, the physical properties such as weight, texture, burning and crushing strength were different from the commercial briquettes. The best briquettes were those produced from 75 percent cow dung-rice hull mixture and 25 percent coconut husk (Treatment 3). These briquettes had the highest crushing strength and. tongest burning time. Based on the sensory evaluation, briquettes produced from 100 percent coconut husk exhibited moderately smooth appearance compared to the other briquettes.

The study was conducted at the Forest Products Research and Development Institute at Los Bafios, Laguna. It aimed to recycle cow dung, rice hull, and coconut husk into briquettes for fuel, determine and evaluate the physical and chemical properties of briquettes produced from cow dung-rice hull mixtures and coconut husk, and determine the best treatment in producing charcoal briquettes from cow dung-rice hull mixture and coconut husk.

The cow dung-rice hull mixture and coconut husk were mixed with cassava starch in the desired proportion of 9:1 (9 parts agro waste: 1 part cassava starch). The mixture was molded using the briquetting machine fabricated at the Forest Products Research and Development Institute at Los Bafios, Laguna.

Different treatments were used: Treatment 0 (Control) commercial abaca charcoal briquettes, Treatment 1 (T)) 100% cow dung-rice hull mixture (200g cow dung-rice hull mixture), Treatment 2 (T2) 50% cow dung-rice hull mixture and 50% coconut husk (100g cow dung-rice hull mixture + 100g coconut husk), Treatment 3 (T3) 75% cow dung-rice hull mixture and 25% coconut husk (150g cow dung-rice hull mixture + 50g coconut husk), Treatment 4 (T4) 25% cow dung-rice hull mixture and 75% coconut husk (50g cow dung-rice hull mixture and 150g coconut husk) and Treatment 5 (T5) 100% coconut husk (200g coconut husk).

Based on the results of this study, briquettes can be produced from cow dung, cow dung-rice hull mnistive and coconut husk, and coconut husk. Chemical properties of the briquettes such as moisture content, volatile combustible matter, ash content and fixed carbon were comparable to commercial briquettes.

The best briquettes were those produced from 75 percent cow dung-rice hull mixture and 25 percent coconut husk (Treatment 3). These briquettes had the highest
crushing strength and. tongest burning time. Based on the sensory evaluation, briquettes produced from 100 percent coconut husk exhibited moderately smooth appearance compared to the other briquettes.
