The method used in making this system by means of data collection, system planning, system analysis, system design and database. The system built on this website uses the PHP programming language and MySQL database. The input needs on the Extracurricular Website of SMP Negeri 7 Jambi City are extracurricular data, student data, and registration data. Process requirements needed are: Login Process, Registration Process, and input, edit, and delete processes. The output data produced is in the form of information that will be attached, including: registration activity reports. The purpose of making this Job Training is the creation of an extracurricular website for SMP Negeri 7 Jambi City. With the existence of a new system that has been designed and created by researchers, it can help facilitate the parties involved in developing extracurricular activities effectively.","PeriodicalId":17695,"journal":{"name":"Jurnal Akademika Kimia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91445410","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}

So many activities in the Karangantu fishing port area, such as a place for landing fisherman’s boats, shipping fish catches, and tourism object. These activities may impact the water quality. This research aims to analyze the water quality and pollution index in Karangantu fishing port. The water sample was carried out by purposive sampling in three stations around the Karangantu fishing port area: the estuary area, the fish auction, and the dock. Twelve parameters were analyzed: temperature, turbidity, transparency, TDS, TSS, pH, DO, COD, nitrate, cadmium, lead, and total coliforms. The water quality analysis result was compared by Class III water classification based on PP RI Nomor 82. Water quality was determined by the pollution index based on the minister of environment decree No. 115/2003. The result indicates that the estuary area is polluted, with a PIj score of 6.35; the fish auction and the dock f are in the moderately polluted categories, with PIj scores of 4.99 and 3.90. The worse pollution can be prevented by raising public awareness about the importance of clean water and providing waste management facilities.","PeriodicalId":17695,"journal":{"name":"Jurnal Akademika Kimia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82173964","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 characteristics of clay significantly affect the quality of the resulting material. This study will study the aspects of natural clay in Gowa Regency, South Sulawesi Province, without the leaching process and with acid leaching. Acid leaching uses 3 M HCl, previously roasted at a temperature of 600 oC. The characterization consisted of metal oxide analysis using XRF, mineral content analysis using XRD, morphological analysis, and compound content using SEM-EDX. The results showed that the primary metal oxide content in natural clay was Fe2O3, Al2O3, and SiO2, the content of Fe2O3 decreased after the raw clay was treated with acid. The main mineral content in the sample is quartz, kaolinite, and hematite. The sample's morphology looks different after being given acid treatment; the acid leaching natural clay sample shows a porous morphology, while the natural clay without acid leaching shows the morphology in the form of lumps. The EDX mapping analysis showed that the number of impurities decreased after being given acid treatment.","PeriodicalId":17695,"journal":{"name":"Jurnal Akademika Kimia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72769044","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}

Analysis using IR spectrophotometer showed the success of ASH synthesis as indicated by the appearance of functional groups -NH2 and -CH2 at wavenumbers 1635 cm-1 and 1473 cm-1. With the continuous method, SG and ASH sorbents that have bound phosphate were then desorbed at various times of 2, 3, 4, 7, 8, and 9 days. The amount of phosphate anion released from SG and ASH was tested using a UV-Vis instrument then modeling was carried out to determine the rate of phosphate release. The desorption results showed the amount of phosphate released from the ASH sorbent was less than that of the SG sorbent. Through modeling, the proceeds of the phosphate release rate follow the Lagergren Pseudo-second Order Kinetic with an experimental QE of 0.22089 M/g for SG sorbent and 0.33333 M/g for ASH sorbent.","PeriodicalId":17695,"journal":{"name":"Jurnal Akademika Kimia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80243384","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 study aimed to examine changes in students' thermochemical concepts in each subject of high, medium, and low ability. Qualitative descriptive research with mixed methods was conducted on SMAN 1 Bumi Raya Morowali, Central Sulawesi students. The study began by giving an initial test to all students of class XI IPA 1 and 2, as many as 60 students, to obtain initial concept data and the basis for grouping subjects on each ability criterion (high, medium, and low). Every two people from each ability group in semi-structured interviews. Thermochemical material is re-taught using a metacognitive skill learning model and given a final test and interview to get concept data after learning to assess conceptual changes. Five concepts become variables in this study: the heat of reaction, enthalpy of reaction in a calorimeter, Hess's law, energy diagrams, and bond energies. The results showed that concept changes occurred in all high, medium, and low ability subjects. Changes in students' conceptions occurred in the concepts of the heat of reaction, reaction enthalpy, calorimeter, Hess's law, energy diagrams, and bond energy. The most significant conceptual change occurred in the subject of medium ability and low ability, namely the concept of bond energy.","PeriodicalId":17695,"journal":{"name":"Jurnal Akademika Kimia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78851758","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}
