The purpose of this research is the optimal carbonization temperature, to obtain economical, environmentally friendly and quality carbon from cassava peel waste. Cassava peel carbon is synthesized through a carbonization process. The method used to manufacture carbon from cassava peel is by calcining it in a furnace at various temperatures of 250℃, 350℃, and 450 for 1 hour. The carbon obtained was tested for ash content, vapor content and bound carbon. In this study, the standard used to determine the characteristics of the carbon produced is the Indonesian National Standard (SNI 06-3730-1995). The results showed that the optimal carbonization temperature for cassava peel carbon was 250℃, where the ash content was 7.14%, the vapor content was 5.32% and the bound carbon was 87.54%. Based on these results, it can be concluded that cassava peel waste can be used as carbon that meets the Indonesian National Standard (SNI 06-3730-1995).

— Malachite green is a dye that is widely used in the textile industry. Malachite green has toxic properties that can cause cancer, skin and eye irritation, and respiratory toxicity. Malachite green is difficult to degrade in waste so it requires serious handling. This study aims to determine the optimum time and optimum mass of ZnO catalyst for malachite green degradation by sonolysis method. The absorbance value was obtained using a UV-Vis spectrophotometer. The results of this study stated that the malachite green solution had a maximum wavelength of 617.2 nm. The optimum time to degrade malachite green with ZnO catalyst was obtained at 30 minutes with %D 85.04% and the optimum mass of catalyst to degrade malachite green with ZnO catalyst was obtained at 0.1 gram with %D 83.31%.

— Eriochrome Black-T (EBT) is a dye that is commonly used in the textile industry to dye silk, wool, nylon, and double fiber, as well as in the laboratory to estimate Ca 2+ , Mg 2+ , and Zn 2+ . If EBT dye is discharged into natural waters, it can have a substantial impact on the aquatic environment's photosynthetic activity since its breakdown components, such as naphthoquinone, are carcinogenic. As a result, its presence in drinking and surface water can be fatal. Therefore, the dyestuff is degraded before being released into the environment so that the environmental pollution can be decomposed. The goal of this study is to find the best timing for EBT degradation using the sonolysis method and to add TiO 2 doping to the ZnO catalyst. The absorbance value measured with a UV-Vis spectrophotometer was used to calculate the percentage of EBT dye degradation. The maximum absorbance (max) of EBT was 535.60 nm, which was used to measure absorbance. The results revealed that the best period for EBT degradation was 30 minutes, with an 81.65% degradation rate. The effect of changing the amount of TiO 2 doping produced the best results, with a degradation percentage of 84.30 % at ZnO-TiO 2 10%.

Indonesia has many spices that have medicinal properties, one of which is cinnamon bark, coriander and cumin which are known to have antioxidants that can lower blood glucose levels, total cholesterol and anti-obesity. The purpose of this study was to determine the effect of cinnamon bark, coriander and cumin on the taste of beef rendang. The hedonic test was carried out with 15 panelists and the parameters observed were color, texture, aroma and taste. The results showed that the addition of cinnamon bark, coriander and cumin had no significant effect on texture, aroma and taste but significantly (P>0.05) on color organoleptic values.

— Carbon material is a material obtained from organic materials through carbonization which is processed into carbon. Corn stalks contain cellulose, hemicellulose, and lignin which have the potential to be used as carbon sources for advanced materials. This study aims to analyze carbon from corn stalks. Corn stalks were carbonized with temperature variations of 250˚C, 300˚C, 350˚C, 400˚C, and 450˚C. The carbon of corn stalks formed was carried out by proximate analysis by testing the vapor content, ash content, and bound carbon. The results of the analysis show that the higher the carbonization temperature, the lower the vapor content and the bound carbon content, while the higher the ash content. In this study, the results of the carbonization of corn stalks in Kecamatan 2 x 11 Kayutanam in accordance with SNI 06-3730-1995 were carbonized samples of 250˚C with a vapor content of 2.9%, ash content of 8.69%, and bound carbon content of 88.41%.
