Food is a basic need for every human being to grow and sustain life. In food, there is what is called BTP or Food Additives. According to the Regulation of the Minister of Health of the Republic of Indonesia No. 033 of 2012 [1], Regarding food additives, boric acid or borax is prohibited from being used in food products. However, many people still use boric acid as BTP in producing food. This study aimed to identify and determine boric acid levels in food samples. The research method used was qualitative analysis with the addition of liquid curcucumin and quantitative analysis using UV-Vis spectrophotometry at a maximum wavelength of 540 nm. The results of identification and determination of boric acid levels showed that sample A had a color change from purplish-red to orange, indicating that the food sample was positive for boric acid. The average level of boric acid in sample A equals 986.947 ppm. The %RSD value obtained is 1.583%, indicating that this test has good precision.

Galam wood (Malaleuca cajuputi) is one of the woody plants that is able to grow well in the peat swamp environment of the South Kalimantan wetlands. Research on the synthesis and characterization of magnetic-hydrochar from galam bark waste for the treatment of sasirangan liquid waste has been carried out. This study aims to determine the characteristics of hydrochar and magnetic-hydrochar against the adsorption ability of sasirangan liquid waste. The results showed that the modification of galam bark into hydrochar and magnetic-hydrochar produced different characteristics based on the analysis of functional groups of infrared spectra. The surface morphology of hydrochar and magnetic-hydrochar also showed the significant differences based on scanning electron microscope (SEM) analysis. The resulting magnetic-hydrochar showed a higher adsorption ability to sasirangan waste than the hydrochar of galam bark and galam bark without modification.

The research aims to study the lipolytic activity of bacteria isolated from soil contaminated with oil. Screening of lipolytic bacteria was performed in Rhodamin-B agar plate containing olive oil. The lipolytic activity was determined by spectrofotometry method toward p-nitrofenil palmitat as a substrate. The result this research showed that there are 15 of 150 isolates bacteria from soil contaminated with oil was confirmed by observing the zone of hydrolysis formed around the growth of colony on Rhodamin B agar plate containing olive oil. One of the lipolytic bacteria identified as higher activity was produced lipase with activity of 7,41 U/ml \u0000 ","PeriodicalId":196624,"journal":{"name":"ALKIMIA : Jurnal Ilmu Kimia dan Terapan","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124574260","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}

Antibiotics have recently gained in popularity due to their usage in medical treatment and the process of removing them from the environment. Amoxicillin is one of the antibiotics that constitutes the study's subject. On a Pt disc electrode and a cobalt hydroxide modified-Pt electrode, the scan rate and pH in the electrochemical oxidation of amoxicillin were investigated. The voltammetry measurement's current peak revealed that changing the electrode surface could increase the electrochemical response and sensitivity of the working electrodes. The Pt/Co(OH)2 modification working electrode had a high sensitivity in the electro-oxidation determination of amoxicillin, with a linear range of the sensor of 20 to 80 M and a limit of detection of 7.15 M for the Pt disc electrode and 3.64 M for the cobalt hydroxide modified Pt electrode. The findings of determination in real samples with electro-oxidation using a modified electrode were in good agreement with a confidence level of 95 percent, according to the comparing method with HPLC.
抗生素最近因其在医疗中的使用以及从环境中去除它们的过程而受到欢迎。阿莫西林是构成该研究主题的抗生素之一。在Pt圆盘电极和氢氧化钴修饰的Pt电极上，研究了阿莫西林电化学氧化的扫描速率和pH值。伏安法测量的电流峰值表明，改变电极表面可以提高工作电极的电化学响应和灵敏度。Pt/Co(OH)2修饰工作电极对阿莫西林电氧化测定具有较高的灵敏度，传感器线性范围为20 ~ 80 M, Pt圆盘电极的检出限为7.15 M，氢氧化钴修饰Pt电极的检出限为3.64 M。采用改良电极对实际样品进行电氧化测定的结果与HPLC法比较，置信水平为95%。
