Abstract

Organic materials derived from wood industry waste such as wood sawdust can be used as an alternative source of energy because the calorific value is quite high, which is 4368 cal /g. The purpose of this study is to determine the best characteristics and composition of alternative briquettes. The variables used are briquette composition and different types of adhesive. The results showed that briquettes with the composition ratio of WWTP and Wood Sawdust 1:2 with the addition of adhesive 40% molasses had a heating value of 4185,90 cal/g. Based on Briquettes in this study. The type of test that has not met the quality standard is the compressive strength test of 43.88 kg/cm². These results have not met the quality standards in SNI 4931: 2010 with the classification of type B briquettes with compressive strength test between 50-60 kg/cm².

Abstract

The larvae BSF (black soldier fly) can be used as an insect-based organic waste recycling technology. Not only for recycling organic waste, BSF larvae (black soldier fly) can also convert organic waste into a product in the form of compost. With so many waste problems, this technology is the most relevant way to deal with the problem. The purpose of this study was to examine the use of BSF (Black Soldier Fly) larvae in the composting process and to find out how much BSF (Black Soldier Fly) larvae were able to reduce organic waste. This study used an experimental method using 16 reactors containing 10000 larvae eggs in each reactor and using a variety of mixed waste. The variation used is the initial weight, in this study used an initial weight of 3 kg and 4 kg and treatment was carried out 2 times. The frequency of feeding was carried out every 3 days and then the weight reduction of the remaining waste in the reactor was measured after harvesting. The average percentage reduction in treatment 1 with an initial weight of 3 kg of waste is 18.25% while the initial weight of 4 kg of waste is 53.65%, different in treatment 2 the average percentage of waste reduction at an initial weight of 3 kg is 60 .25% and at 4 kg by 30.25%. The results of the compost will be compared with the quality standard of SNI 19-7030-2004, the results of the study show that treatment variation 2 at the initial weight of 3 kg of waste is closest to the quality standard based on the value of pH, water content, C-organic, N-organic and C ratio /N.

Abstract

Waste processing that is less than optimal causes the generation of large amounts of waste so that action is needed to process it into useful new products, for example into briquettes. The implementation of adding raw materials in making briquettes with waste that has low economic value is expected to improve the quality of briquettes. Paper waste and used cooking oil have the potential to be processed as additional raw materials in the manufacture of briquettes in producing alternative fuels. Based on the results of characteristic testing, the quality of the briquettes increased after the addition of paper waste and used cooking oil. The water content of briquettes from 5,12% decreased to 1 – 2%. The ash content of briquettes from 10,01% decreased to 5 – 7%. The calorific value of briquettes from 4902 cal/g increased to 5200 – 5700 cal/g. The compressive strength of briquettes from 4,38 kg/cm2 increased to 5,51 – 9,48 kg/cm2. The immersion treatment of used cooking oil has an optimum time limit because it can affect the solidity of the charcoal when testing the compressive strength. The addition of paper waste and used cooking oil to the combustion rate increases the combustion power of briquettes and the flame lasts longer so that the combustion rate range obtained is small. The emission of carbon monoxide (CO) produced by the briquettes in this study is relatively low because it is still far below the required quality standards.
