The compounds were initially prepared using the hydrothermal method at 180°C, and part of the active materials were reheated at 500°C in the air to improve the crystallinity and reduce the impurities. The materials were characterized by X-ray diffraction, scanning electron microscopy (SEM), Raman spectroscopy, and BET surface area. Anodic electrochemical behavior was examined by cyclic voltammetry (CV), galvanostatic cycling, and electrochemical impedance spectroscopy (EIS). Results show that (Fe1/2Sb1/2Sn)O4 reheated at 500°C delivers a better capacity of ∼400 mAh/g at 0.005-1.0 V voltage range up to 60th cycle. When we cycled a higher cut-off voltage of 0.005-3.0V, higher reversible capacity and higher capacity fading were noted due to alloying and conversion reaction of these mixed oxides.

The economic improvement of fishers and boat owners is very dependent on this effort. Efficient fishing technology will reduce fishing operating costs with a larger number of catches. The description above indicates a need for research on the effect of changing fishing patterns after engine power efficiency has. The calculation is carried out on fishing gear equipment, namely power block, net length, net weight of the net, and net sinking speed on fishing operations’ efficiency. With the efficiency of fishing gear, the income of fishers increases more than the income before efficiency is carried out. The efficiency of fishing operations is strongly influenced by fuel, crew members’ consumption, fishing patterns, number of crew members, and operational effectiveness. Data analysis was carried out in two stages, namely regression analysis and efficiency analysis. Regression analysis aims to determine the magnitude of ship speed on fish catch, and efficiency analysis aims to determine engine power efficiency, operating time efficiency, hold efficiency and fishing gear efficiency. The results show that the calculation of engine power efficiency is about 75%, the operating time efficiency is around 55%, the hold efficiency is around 35%, and the fishing gear efficiency is around 73%.","PeriodicalId":13712,"journal":{"name":"INTERNATIONAL CONFERENCE ON ENERGY AND ENVIRONMENT (ICEE 2021)","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74688163","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}

The inhibition of sponge methanol extract against the growth of Escherichia coli (EC) and Staphylococcus aureus (SA) and Malassezia furfur (MF) fungi was the largest by CR sponge methanol extract, but did not have inhibitory activity against Candida albicans (CA). The growth and characterization of the metabolites produced by sponges are influenced by the environmental conditions of coral reef growth and cover.","PeriodicalId":13712,"journal":{"name":"INTERNATIONAL CONFERENCE ON ENERGY AND ENVIRONMENT (ICEE 2021)","volume":"42 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84859876","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}

This e-module is designed on atomic structure material. The used method is pre-experimental using one group pretest-posttest only design. Research instrument was involved in a scientific literacy ability test consisting of 10 description questions. Sampling technique was used purposive sampling. Data analysis technique was tested using a paired sample t-test and N-Gain value. From the sample testing, it was obtained a significance value of p<0.05 (p=0.000). This data showed that there was a significant difference between the scientific literacy abilities of students before and after using e-modules. The average value of N-Gain was found that the increase in students’ scientific literacy skills was 0.74 with high category. This value is detailed as 0.87 (high) for the context aspect, 0.75 (high) for the knowledge aspect, 0.69 (medium) for the competency aspect and 0.73 (high) for the attitude aspect. Based on the data, it can be concluded that the use of e-modules on the atomic structure material was found to be effective in improving students’ scientific literacy skills.","PeriodicalId":13712,"journal":{"name":"INTERNATIONAL CONFERENCE ON ENERGY AND ENVIRONMENT (ICEE 2021)","volume":"38 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83317231","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}
