The Impact

One way to improve compost quality of typical organic waste is by addition of additive such as wood chips. This study aims to analyze the impact of the wood chips addition (ratio 1:10) on compost quality of typical organic waste (fruits, vegetables, yard waste, and food waste) in home composter, and to compare the compost quality with the standard of domestic compost according SNI 19-7030-2004. Analysis was conducted on composts raw material, compost maturity process in every 5 days measurement, and on compost product. Analysis of compost product of typical organic waste with addition of wood chips showed that parameters of temperature, moisture content, and pH of vegetables and yard waste has complied the standard whilst parameter of C/N ratio has not complied. The addition of wood chips caused the drop of compost temperature and moisture content, resulted in the decomposition process located in aerobic condition, resulted in production of compost in form of humus in greater volume. The addition of wood chips also caused the compost pH and C/N ratio increased.Keywords: compost quality, home composter, typical organic waste, wood chipsAbstrakSalah satu upaya untuk memperbaiki kualitas kompos sampah organik adalah dengan penambahan bahan aditif, seperti serpihan kayu.

The article presents research on the preparation of raw materials, creation and granulation of compositions from obsolete sludge deposits of peat and biomass. Studies of raw material preparation processes have shown that obsolete sludge deposits have excessive ash content. To reduce ash content, it is advisable to add peat and biomass to sludge. During the study of peat, it was determined that peat extracted from the floodplain of Irpen has a high ash content, so for further research used peat from Chernihiv. The created compositions were subjected to granulation in different compositions and ratios. Preliminary dehydration of peat in the drying cabinet and moistening of the sludge were performed to create different sludge-peat mixtures with different moisture content of sludge and peat. When creating two-component compositions to sludge-peat add biomass. Studies have allowed us to choose the optimal ratio for granulation.

Aleurites Moluccana

Candlenut (Aleurites moluccana) is a plant with various benefits. Currently, candlenut is mostly used as a spice, candlenut shells also has a high calorific value so that it can be used as fuel. Candlenut has shells which is an organic waste. Candlenut shells have a hard texture and high carbon content. Most of the candlenut shell is used as fuel and only a small part is used as raw material for carbon production. Candlenut shell have good physical and chemical properties as carbon raw materials. Activated carbon is one of the carbon phases that can be used for various applications. In this paper, we report on the synthesis and characterization of carbon from candlenut shells to obtain high-quality carbon by controlling the carbonization temperature. In carbon production, we use variations in carbonization temperatures of 300, 400, 500, 600 and 700 C. Proximate analysis was carried out to determine the moisture content, ash content, volatile matter content and bound carbon content. Analysis of the effect of carbonization temperature on the quality of carbon from candlenut shells resulted in the highest carbon in the sample with a temperature of 700 C, producing carbon with 5.32% moisture content, 9.40% ash content, 12.76% volatile matter content, and fix carbon content 72,52%
