It includes the mutiara catfish ( Clarias gariepinus ) growing relatively fast and having a fairly high nutritional content. It can be used as a flavor enhancer in the form of instant broth powder. This research aims to determine the formulation and best quality of instant catfish broth powder products using the Spray Drying method as a natural flavor enhancer that the public likes and follows the Indonesian National Standard. This research was started by sampling the fish and separating the meat. Then, an analysis of fish meat, including a proximate test, was prepared and continued with making broth with different recipes based on the added weight of catfish meat (in percentage) with several spices used in several formulations: 75% (F1), 70% (F2), 65% (F3), 60% (F4) and 55% (F5) by boiling and mixing all the supporting ingredients according to the predetermined formulations. Next, the drying process was carried out using the Spray Drying method, followed by an organoleptic test to obtain a chosen formula and, finally, the quality of the instant Mutiara catfish broth powder product was tested. The instant powder (F4) was the selected product based on the organoleptic test, because this formula is the most preferred product by the panelists. The results of the analysis of physical, chemical, microbiological characteristics complied with SNI 01-4218-1996 concerning broth powder. In addition, the shelf life of this product with metallized plastic packaging was 1,028.24 days.","PeriodicalId":17697,"journal":{"name":"Jurnal Pendidikan Kimia","volume":"54 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73043364","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}

In developing good mastery of learning concepts, students' critical thinking skills are needed. The development of critical thinking skills can make students give up, so it takes a firm belief in students' abilities in overcoming difficulties so they can become more advanced. This study aims to see the effect of the Think Talk Write (TTW) and Self Efficacy on students' critical thinking skills in the matter of reaction rate. The sample used consisted of 2 classes at SMA Adhyaksa 1 Jambi City. The data collection instruments used were observation sheets, self-efficacy, and essay tests. The data analysis used was 2-way ANOVA. The results showed that learning using the TTW and Self Efficacy affected students' critical thinking skills with an average of 71% from meeting 1, meeting 2, and meeting 3.

One of the plants with flavonoids is patat (Phrynium capitatum), which is usually used as food wrapping material. This study aims to quantify total flavonoid content, antioxidant activity and identify flavonoids from patat leaves ethyl acetate extract. Patat leaves sample cleaned, dried, and grinded. Grinded patat leaves were macerated gradually for 2 × 24 hours with n-hexane, ethyl acetate, and methanol solvent. The extract undergoing total flavonoids test guided with AlCl3 and CH3COONa. Extract with the biggest flavonoids content proceed to antioxidant activity test by SOD (superoxide dismutase) method and analyzed for the flavonoid structure by UHPLC MS/MS (ORBITRAP HRMS). The biggest total flavonoids are ethyl acetate extract with 8.678 mg QE/g; then methanol extract with 5.296 mg QE/g; and n-hexane extract was not tested because of negative results in the qualitative test. The antioxidant activity of the ethyl acetate extract of patat leaves is classified as inactive, with an Ic50 value of 488.299 ppm. The low antioxidant activity is due to the sample, which is still a matrix containing many compounds. The flavonoid compounds identified by its fragmentation pattern were kaempferide, formononetin, and pinostrobin.","PeriodicalId":17697,"journal":{"name":"Jurnal Pendidikan Kimia","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76387444","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}
