The benefit of this research is to present a simple laboratory that can be used in physics education class as a test tool for heat absorption. The research method that applied is Microcomputer Based Laboratory (MBL). The software that used is LabVIEW which connected to Arduino Uno hardware and heat source. The appropriate set of tools and materials is then tested for eligibility. The feasibility test of the device is reviewed from the aspect of content, linguistic, presentation and graphic by an expert validator as well as the compatibility of the findings with the theory. The results found that the darker the color of the object, the greater the ability of heat absorption and vice versa. Changes in power at a light source can affect changes in maximum temperature in the color absorption of heat. The greater the power provided by the light source, the greater the increase in maximum temperature. This development research concludes that the tools are feasible to use and appropriate based on existing theories.","PeriodicalId":42020,"journal":{"name":"Jurnal Pendidikan Fisika Indonesia-Indonesian Journal of Physics Education","volume":"16 1","pages":"41-46"},"PeriodicalIF":0.6,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67006564","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 data used are weather parameters in the form of air temperature data, air humidity, rainfall, duration of solar radiation and wind speed as input data and data on dengue hemorrhagic fever cases as the target data. This study aims to see the confirmation of dengue hemorrhagic parameters in Pontianak. The benefit in the field of education is that students and teachers are aware of the dangers of dengue because it can cause death. The method used is back propagation neural networks with the best network architecture in predicting cases of dengue hemorrhagic fever are [50 40 30 1] and binary sigmoid activation function, bipolar sigmoid and linear function. The activation function will determine whether the signal from the neuron input will be forwarded to other neurons and is also used to determine the output of a neuron. Network training correlation value is 0.9995 (very strong correlation) with MSE 0.0001 and network testing is 0.9325 (very strong correlation) with MSE 1.61. Determination coefficient serve as accuracy with values obtained is 0.85, which means that 85% of weather parameters can be used as input in predicting the incidence of dengue hemorrhagic fever in Pontianak City.","PeriodicalId":42020,"journal":{"name":"Jurnal Pendidikan Fisika Indonesia-Indonesian Journal of Physics Education","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2019-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47843549","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 purpose of this study was to map the student problem-solving skills after inquiry learning in Physics subject, impulse, and momentum in class X SMAN 1 Prambanan, Yogyakarta. Experimental research model with one-shot case study design was used in this study. Data collection was performed through essays at the end of the learning process. The results of the mapping show that students have different problem-solving skills levels at each stage. At the stage of problem identification, students were in a very good category. At the stage of planning the problem solution and problem-solving implementation, the students were in a good category, while in results evaluation, the students were in a fairly good category. The result of this study can contribute to giving the point of view to the teacher about students' problem-solving skills level based on the indicators as well as giving the additional information as a literature in the topic of students’ problem-solving skills after inquiry learning.","PeriodicalId":42020,"journal":{"name":"Jurnal Pendidikan Fisika Indonesia-Indonesian Journal of Physics Education","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2019-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42632836","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}

Inversion of gravity data is done by first determining the simulation data. Forward modeling uses simulation data to produce an initial guess inversion model expressed with parameters n0 (1), n0 (2), n0 (3) and n0 (4). The forward modeling is performed on the next initial guess that the value of the misfit is as small as possible through an iteration using the Jacobian matrix. Accuracy of inversion results is determined by the initial guess and the number of iterations. The results obtained show that inversion modeling is more valid in the inversion modeling process compared to advanced modeling, because the value of the parameters sought is generated from mathematical observations of the observation data. Guesses greatly affect the results of inversions obtained. Initial guesses are given in the form of parameters n0 (1), n0 (2), n0 (3) and n0 (4). The initial guess for the parameters n0 (1), and n0 (2) that are made far deviant does not affect inversion. The initial guess for the parameters n0 (3), and n0 (4) that are made deviating far influences the inversion caused by a very small RCON value so that the result is NAN","PeriodicalId":42020,"journal":{"name":"Jurnal Pendidikan Fisika Indonesia-Indonesian Journal of Physics Education","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2019-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46003231","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}
