To overcome these problems, a technology that can be studied and controlled according to the standards is needed. It can also facilitate pond farmers to facilitate pond air quality and the automation of standardization of water quality indicators. This development uses internet-related matters in data communication between prototypes with farm farmers. The development model used is prototyping. For the testing process, (3) trials are conducted: (1) evaluation testing, with test results, prototypes, get a percentage of 100% with a very effective category. (2) validity testing, with a margin of error of 4.38% and the overall sensor test results under 4.38%.

In determining student learning outcomes on student learning satisfaction with distance learning during the Covid-19 pandemic, a study was carried out using the Simple Additive Weighting (SAW) method. This study aims to determine student learning outcomes during the Covid-19 pandemic. The type of research used in this research is applied research, in which this research is directed to obtain information that can be used to solve problems. The method used is Simple Additive Weighting (SAW) by comparing the results of the decision of the SAW method between the weighting based on the Fuzzy Logic method and the weighting based on the ROC method. The subjects involved in this study were 36 students of Vocational High School (SMK). Data collection in the study was carried out using direct observation, interviews, and questionnaires. The criteria contained in the questionnaire are factors that affect the process of student learning outcomes on learning satisfaction during the Covid-19 pandemic. The criteria used are device ownership, accessibility, ease of obtaining materials, method accuracy, monitoring ability, interactivity, and independent learning. From the seven criteria, the priority scale is determined. The results showed that the analysis of the search for weight scores using the Simple Additive Weighting (SAW) method using Fuzzy Logic and Simple Additive Weighting (SAW) using the Rank Order Centroid (ROC) method resulted in different sub-criteria weighting scores, so it can be said that the combination of SAW- ROC provides a more accurate and more selective selection of the number of students.","PeriodicalId":181108,"journal":{"name":"International Journal of Natural Science and Engineering","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116411633","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}

On the other hand, the problem of water scarcity is the main thing, because the characteristics of karst rocks can escape, dissolve and absorb water. The condition of the ex-niche mining and water shortages are two different problems. But in this study, trying to combine these problems into a solution with the aim of making experiments that can make limestone from Pecatu Hill have the potential to hold water for a long time in the form of a miniature reservoir model. This miniature reservoir model is made with a mixture of clay suspensions of various concentrations (0%, 5%, 10% and 15%). This miniature reservoir model is tested for discharge and absorption of water which is assumed to be rainwater puddle to determine the ability to absorb rainwater. The result of this test is that the miniature reservoir with a mixture of 15% clay suspension has the ability to withstand a decrease in rainwater shrinkage of 0.04L / minute and has a small water absorption capacity of 10.91% compared to other concentrations. This shows that the miniature limestone reservoir of Pecatu Hill with a mixture of 15% clay suspension has potential as an instrument for harvesting and collecting rainwater. So this is expected to be utilized by the villagers of Pecatu Hill as an instrument for harvesting and collecting rainwater.","PeriodicalId":181108,"journal":{"name":"International Journal of Natural Science and Engineering","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133026214","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}
