This study uses an experimental method where iron sand has gone through the coprecipitation process and the water quality parameters measured are temperature, pH and conductivity. The measurement results showed that well water after being mixed with iron sand decreased for temperature and conductivity parameters and increased for pH parameters. Of the three parameters, only one parameter does not meet the water quality standard requirements, namely the pH value before being mixed with iron sand which is below the standard, which is 6.32. However, after the well water was mixed with the four samples of river iron sand, the pH value increased to 7.99, 7.85, 7.75, and 8.00 so that it was able to meet water quality standards for pH parameters.","PeriodicalId":137476,"journal":{"name":"KONSTAN - JURNAL FISIKA DAN PENDIDIKAN FISIKA","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134497805","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 teacher-centered method causes less meaningful learning for students. Learning is still largely theoretical and infrequently relates what students are taught to their everyday lives. The purpose of this study is to evaluate how well students learn physics utilizing a participatory learning model and critical problem-solving skills. The study used an experimental design (control group pre-test post-test design) involving class VIII SMPN 3 Batukliang, with the research sample being class VIII A students as the experimental class and class VIII B students as the control class. A straightforward random sample method was used for sampling. Learning outcomes determined by testing are used to determine student achievement. A descriptive and statistical analysis of student achievement in two classrooms (experimental and control) was conducted. Average scores for each treatment group are used in the descriptive analysis, whereas variance is questioned in the statistical analysis using the t-test. The effect of the participatory learning model using critical problem-solving techniques (experimental group) was measured by the difference in student achievement when compared to the control group after analysis using a t-test. The t-test findings show that, at the 95 percent confidence level, the t-count value (4.249) is higher than the t-table (1.675). Based on these results, it can be concluded that the participatory learning model using critical problem-solving techniques has a significant impact on increasing students' learning achievement in physics.","PeriodicalId":137476,"journal":{"name":"KONSTAN - JURNAL FISIKA DAN PENDIDIKAN FISIKA","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129661961","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}

CaO is a compound that can be applied in various fields such as biomaterials, electronics, agricultural industries, and others, for example as a source of biological calcium which plays a role in the growth and survival of shrimp, lobsters, and fish. This study aims to examine the effect of Calcination Temperature on calcium oxide (CaO) characteristics of pearl clam shells (Pinctada Maxima). The procedures carried out in this study include the preparation of pearl clam shells (pinctada maxima), the formation of Calcium Oxide (CaO) using the calcination method which is then continued with the characterization of the test sample. The CaO characteristics studied include CaO characteristics such as CaO compound content, powder size, powder density, bulk density and porosity. The results of measuring the CaO characteristics of pearl clam shells with variations in calcination temperature get an increase in calcination temperature resulting in the CaO yield value tending to decrease with an increase in CaO levels. Bulk density is not particularly affected by calcination temperature, but powder density tends to increase with temperature increase, whereas, porosity and particle size have smaller values. Interestingly, the values of density and porosity are inversely proportional which is closely related to empty cavities or pores formed as a result of differences in calcination temperature.","PeriodicalId":137476,"journal":{"name":"KONSTAN - JURNAL FISIKA DAN PENDIDIKAN FISIKA","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117076276","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}
