Production of fuel briquettes form nipa palm shell mixed with fat dregs
Production of fuel briquettes form nipa palm shell mixed with fat dregs

This research is to study the production of fuel briquettes from the Nipa palm and Fat dregs in the ratio 1:0 1:0.1 and 1:0.3 kg respectively. We performed a study of the properties of the fuel briquette produced and also study the heating value moisture content ash volatile matter and fixed carbon. The results showed that the heating value of the fuel briquette is the most fuel briquette sclera ratio of fat and the residue was 1:0.3.The heating value of 5370 calories per gram. Followed by fuel briquette ratio 1:0.1 and 1:0 with heating value of 5300 and 5280 calories per gram respectively. The results also showed that increasing the amount of fat dregs ingredients make heating value of fuel briquettes increase as well. Also when the fuel briquette production tested by igniting the fuel briquette with no mixing of Fat dregs can ignite flammable odorless and smokeless. Fuel briquettes that are mixed in a ratio of 1:0.1 and 1:0.3 of fat can ignite flammable. The smell of burning grease and smoke residue to consider using a combination of fat dregs in fuel briquette for reduce the amount of waste that could affect the environment.

The aim of this research is to study white and colour resist printing of dye extracted from dry nipa palm shell. The printing recipes and fixation condition were studied in this work. The result of white resist printing showed that 30 % owp of sodium carbonate (Na2CO3) was used to be a resisting agent. The steam fixation for 15 minutes was suitable to show a good white resist printing in whiteness and sharpness of printing pattern. The whiteness value was 35.05. The washing and rubbing fastness were good to very good and light fastness was fair. The tensile strengths of warp and weft directions were decreased to 10.29 % and 4.25 % respectively. The colour resist printing was using Curcuma longa Linn. powder as illuminant dye. The dye was miscible in 30 % owp of sodium carbonate. The colour resist printing results were corresponding as white resist printing results. The 15 minute of steam fixation showed a good colour resist printing. The Curcuma longa Linn dye could be fixed on silk fabric and showed a good colour strength and sharpness of pattern. The washing and rubbing fastness were good to very good. And light fastness was fair. The tensile strengths of warp and weft directions were decreased to 18.37 % and 4.18 % respectively.
