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).","PeriodicalId":213875,"journal":{"name":"Jurnal Periodic Jurusan Kimia UNP","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122855597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

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%.","PeriodicalId":213875,"journal":{"name":"Jurnal Periodic Jurusan Kimia UNP","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133570313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
