Abstractâ€” The use of biomass from mahogany wood waste briquettes as a substitute fuel for oil and gas requires briquette technology. Mahogany wood briquette is able to convert into fuel with a fairly good conversion efficiency, high density and ease of storage and distribution. The purpose of this study was to determine the effect of pressure variations on the density, moisture content and rate of burning of mahogany wood waste briquettes. The process of making charcoal biobriquettes begins with the carbonization process with a temperature of 400 ÌŠC, then smoothed and sieved with a size of 80 mesh - 100 to get the same size, and using tapioca adhesive 30% of the weight of the mixture. The mixture is put into a molding machine and then printed with a pressure of 80 kg/cm2, 115 kg/cm2, 150 kg/cm2, and 185 kg/cm2. Charcoal biobriquettes are dried in an oven at 105 ÌŠC for 1 hour. In this research, the mass density and moisture content of the mahogany wood waste met the Indonesian biobriquette standards, the results of this study obtained the higher density of 0,55 g/cm3at a pressure of 150 kg/cm2. The results lowest water content of 47,2% at a pressure of 185 kg/cm2. The lowest combustion rate is 0,257 g/min at a pressure of 185 kg/cm2.Â Keywordsâ€”: mahoni wood waste; pressure; moisture content; combustion rate.

Bio-briquette is a solid fuel made from organic waste and mixed with other materials and then printed using a certain pressure to get the desired shape and characteristics. This research is focused to know the influence of variation of pressure on the density, moisture content and combustion rate on the bio-briquette of sengon wood waste with variation of pressure 45 kg / cm2, 80 kg/cm2, 115 kg /cm2, 150 kg/cm2. Use of this research obtained the highest density 0.47 g/cm3 on the bacon of sengon woodÂ bio-briquette with the pressure of 150 kg/cm2, the highest moisture value is 6.6 % in the bacon of sengon wood bio-briquette with pressure 150 kg/cm2 and burning at an average of 0,35 g /min of sengon wood waste with a pressure of 150 kg /cm2. The greater the pressure the higher the density, the lower the water content and the lower the burn rate.

The purpose of this study was to obtain activation energy with the rate of combustion air, reduced mass weight and reaction rate of combustion of charcoal briquettes from biomass waste of old coconut, young coconut, cacao waste with carbonization at a temperature of 400oC, for 30, 60, 90 and 120 minutes. The study was conducted in a laboratory, with 3 (three) repetitions. The study was carried out by sorting raw materials, chopping, drying, carbonizing, grinding, sifting, adding tapioca glue to print, and pressing at 115 kg / cm2. The results of the briquette were analyzed for heat, the highest calorific value of old coconut waste, young coconut, cocoa waste was analyzed for activation energy during the combustion process using DSC by varying the air heating rate of 20, 30, 40 ml / minute. The highest yield of old coconut briquette heating value is 6,927 cal/g with 90 minutes carbonization time. The lowest activation energy is 133.20 joules / gram on old coconut briquettes with an air speed of 40 ml / minute. In the rate of combustion reaction by thermogravimetry with Thermal Gravimetry Analyzer (TGA), the greatest reduction in mass weight on old coconut waste briquettes compared to young coconut and cocoa waste briquettes was 55.34% from 590.5 oC to 599.2 oC.

Housewives need dishwashing soap and clothes washing soap every day. It would be more economical if these ingredients could be made themselves and would be more economical. The plan for this community service activity is to provide training in making liquid soap which will be carried out in Tawangrejo Village, Kartoharjo District, Madiun City, Madiun, whose are PKK’s member. The aim of this activity is to provide knowledge, insight and assistance in making liquid soap which is used for washing dishes and washing clothes. The methods used in community service activities use presentation and demonstration methods. Community Service Activities have been carried out well and smoothly and the mothers are very enthusiastic and motivated to do it independently. Attended by 30 mothers, 12 participants of the Unmer Madiun KKN, the mothers took part in mixing the soap ingredients, stirring so they took part in the practice of making liquid soap. The result of this service activity was that the participants received products and understood entrepreneurial opportunities in liquid soap products as dishwashing and clothes washing soap

Natural fiber reinforced composite materials are increasingly being developed as an alternative to metal due to their lightweight, strong, and environmentally friendly properties. This study used pineapple leaf fiber and shell powder with an epoxy matrix to determine the optimal composition to improve the tensile properties of the composite. The purpose of this study was to determine how much fiber influences the tensile strength of pineapple leaf fiber and shell powder with an epoxy resin matrix. Specimens were made using the hand lay-up method and alkalization treatment, with a fixed composition of 60% epoxy, while the content of pineapple leaf fiber and shell powder varied from 10%; 15%; 20%; 25%; 30%. Tensile tests were carried out in accordance with ASTM D638. The results showed that the composition of 60% epoxy, 25% pineapple leaf fiber, and 15% shell powder produced the highest tensile strength of 20.80 MPa and the highest elastic modulus of 2029.4 MPa, while the highest strain value of 0.0228 was obtained in the composition of 60% epoxy, 15% pineapple leaf fiber, and 25% shell powder. In general, pineapple leaf fiber contributes to increasing tensile strength, while shell powder increases material stiffness through a more even stress distribution.
