Abstract

In 2021 the total amount of waste from various types of waste in Indonesia alone will reach 68,5 milion tons. Based on these data, as much as 17 percent, or around 11,6 milion tons, was contributed by jenna R.Jambeck from the University of Geogia in 2010, there were 275 tons of plastic waste produced worlwide. Around 4,8-12,7 milion tons of them are waste and pollute the sea. Indonesia itself has a coastal population of 187,2 ,milion which annually produces plastic waste. Around 0,48-1,29 milion tonnes of plastic waste is thought to have polluted the oceans. To overcome this, proper management of plastic waste is needed, one of which is by making paving blocks made from plastic waste. The study aims to determine the characteristics of thr various composition paving blocks according to the Dquality standard, which is used for garden pavements and other uses. In this study, aratio of 1:1:1 was used for plastic, sand, and oil. Then coconut shells were added to the treatment P1 as much as 3%, P2 as much as 6%, P3 as much as 9%, and P4 as much as 12% of the paving block volume paving block quality standardD has requirements, namely the maximum value obtained from the results of the compressive strength test is 10 Mpa and water absorption is 10%. From the result of the research that i did, it was found that the variations in the P treatment were closestto the quality standard D, with a compressive strength test value of 5,84 Mpa. Keywords : Coconut Shells, Paving Blocks, PET, Plastic, Waste.

Abstract

Sugarcane bagasse is the remaining solid waste from sugarcane (Sacharum officinarum) milling which has the potential to be developed as solid fuel in the form of pellets. The purpose of this study was to determine the effect of variations in pressure and particle size on the characteristics of pellets from sugarcane bagasse. The research was carried out with a combination of variations in particle size (fine, medium, and coarse) and pressure (1, 2, and 3 tons). The results showed that sugarcane bagasse has the potential to be developed as a pellet fuel because it has a relatively high calorific value, an average of 16.53 MJ/kg. Sugarcane bagasse pellets meet SNI 8675-2018 standards in terms of moisture content, density, and ash content. The results showed that although the ash content of the pellets was affected by the particle size, in general, the characteristics of the pellets were not significantly affected by the treatment factors (pressure and particle size as well as their interactions). Sugarcane bagasse pellets have a high water absorption capacity, so they require a good storage method. Keywords: Densification, Density, Pressure, Particl Size, Strength

Abstract

This study aims to determine the effect of adding coconut shell biochar on biogas production from a mixture of chicken manure and cow manure. The research was conducted using a batch type digester with an active volume of 2000 mL. The substrate consists of a mixture of chicken manure and cow manure with a weight ratio of 1:1 and 3:1. Biochar from coconut shells is mashed and added at a rate of 3 grams. Parameters observed included ambient temperature, initial and final pH, biogas production and methane content in biogas. The results showed that the addition of coconut shell charcoal had a negative effect which was marked by a decrease in cumulative biogas production. The highest cumulative biogas production was obtained in the treatment without the addition of biochar, both K1B0 and K2B0. Biogas from the K2B0 treatment has a higher CH4 content than those of other treatments. Keywords: Biogas Production, Methane, pH, Substrate Rasio, Temperature

Abstract

Indonesia is an agrarian country because it has abundant agricultural products, one of its mainstay is corn. Besides rice, corn is one of the staple foods consumed by Indonesian people, but only the corn’s grain are used in corn. The cornhusk and corn cobs are usually thrown away or just burned because they are not used. One of the way to process corncobs waste is by chopped corncobs to be used as animal feed. Corncobs that have been separated from the grains of corn were chopped using a chopper machine (Chopper). All this time, these machines have been widely used by society. However, it still raises problems related to the chopper machine. This study uses the observed parameters, namely the enumeration work capacity, fuel consumption, the uniformity of the enumeration results, and the yield. Based on the result of the study, the effect of treatment on yield was not significantly different, with an average yield value of 94.89%. The highest chopping results of corn cobs is at high rotational speed of 1245 rpm with an engine working capacity of 332.88 kg/hour. The lowest fuel consumption is at a rotating speed of 890 rpm with a fuel requirement of 0.74 liters/hour. The effect of treatment on the distribution of chopped results was not significantly different, with the average value for fine chopping 67.29% and 32.71% for coarse chopping. Based on the ANOVA test, the effect of treatment on fuel productivity was not significantly different, with an average fuel productivity value of 301.61 kg/liter. Keywords: Chopper, Chopper Machine, Corn, Corncobs, Rotating Speed.
