Abstract

The purpose of the study was to determine the correlation between the level of online game addiction and student achievement in the Mathematics Education Study Program, UIN Raden Intan Lampung. The method in this research was quantitative with the type of correlation research. The data collection technique used a questionnaire and tested it to see the validity and reliability. The data analysis technique in this study used the normality test using the Kolmogorov Smirnov method and the linearity test using SPSS software version 24.0, and hypothesis testing using a correlation test with a significant level of 0.05 or 5%. The study results were that of the 30 questionnaires tested, 25 questions were feasible to use. The reliability test has a value of rcount > rtable. The normality test got a significant value of 0.065 and 0.066 on online game addiction and learning achievement. So it can be said that there is a significant correlation between student achievement and online game addiction, and the value is 0.307, which means correlation

Abstract

The ability to solve problems and the ability to communicate mathematically in a student's study is a skill that students need to provide asa basis for resolving mathematical problems. Based on the results of daily mathematicians saying that the ability to solve problems and mathematical communications at MTS Darul A'mal Metro is still low, judging by the student's process of resolving mathematical problems caused by many who pay no attention to the explanations presented by teachers and students are not able to solve math problems properly. In addition, there are less diverse learning models. To address the problem, researchers applied the CRI model with IOC techniques. The purpose of this study is to know the difference between the CRI learning model with the IOC and the direct learning model of problem solving and student mathematical corover. This research is an experiment quasy research. Sample demonstration techniques using the simple random sampling technique. The samples in this study are class VII D as an experiment class and class VII E as a control class. The instrument used to collect data is a description test. The custom data analysis technique used was the normality test, the homogenity test and the hypothetical test used the manova test. Based on manova's test results of Pillai's Trace, Wilks' Iambda, Hotelling's Trace, Roy's Lagest Root  and value a test criteria  which means that the p-value value is smaller than a test criteria, so that ho is thus denied it can be inconclusive that there is an influence between the CRI model and the IOC techniques of student solving and mathematical communication capability

Abstract

Mathematical problem solving ability is one of the things that must be owned by students in learning mathematics. Students have low mathematical problem solving abilities caused by difficulties in solving mathematical problems that require logic. The research is aimed to determine the effect of the Alqurun Teaching Model on mathematical and gender problem solving abilities. This research is quantitative research. The population were 264 in eighth grade students of SMPN 17 Bandar Lampung. Sampling technique used by sample random sampling technique. Data analysis techniques used the normality test with Liliefors test and homogeneity test with Barlett test. Hypothesis testing using the two-way cell ANAVA test is not the same. The results showed that there was an influence of the Alqurun Teaching Model (ATM) learning model on mathematical and gender problem solving abilities. The mathematical problem solving abilities of female students are better than male students in the Alqurun Teaching Model learning.

Abstract

Low understanding of mathematical concepts in mathematical learning is due to a lack of learning strategies. Therefore, this study aims to analyze the influence of Habits of Mind (HOM) on students' visual thinking in understanding mathematical concepts. Costa and Kallick's 16-category HOM questionnaires were used as research instruments. Data analysis techniques used data reduction, data presentation, and conclusion withdrawal. Based on the results of data analysis, it is known not to have the ability habits of mindfully. The results showed the profile of HOM in the understanding of the mathematics of students with visual thinking is still classified as sufficient criteria. And overall, the average Habits of Mind indicator obtained is 66.61% included in the requirements enough. Students who have Habits of Mind and good visual thinking will more easily understand mathematics. In contrast, Habits of Mind and visual thinking that is not good will be more difficult to understand mathematics.

Abstract

Biodiesel is biodegradable and non-toxic and has a low carbon content, high lubricity, and Biodiesel is biodegradable and non-toxic and has a low carbon content, high lubricity, and higher ash point than diesel. The purpose of this study was to obtain data on the physicochemical properties of biodiesel from waste cooking oil (WCO) produced with different amounts of catalyst in the transesterification process. Methods This research carried out a two-step process: (1) esterification with an acid catalyst (H2SO4) and (2) transesterification with an alkali catalyst (KOH). The remaining frying oil is degummed by adding 2% H3PO4. Furthermore, the esterification process was carried out by adding 2% (v/v) H2SO4 at 800 rpm for 90 minutes. The transesterification process using an alkaline catalyst (KOH) was varied from 0.7-1.5% at a temperature of 60 oC with a rotation of 800 rpm and a time of 90 minutes. In the ester/transesterification process, the ratio of methanol: oil is 1:2 (v/v). The biofuels are then tested for cetane number, flash point, density, viscosity, calorific value, and others. The results showed that the amount of wet catalyst (KOH) in the transesterification process gave a difference in the yield of WCO oil. The optimum value was obtained at the amount of 1% KOH catalyst, which was 85%.

Abstract

The number of rivers and canals in most parts of Indonesia is large enough to be developed into a micro-hydro power plant. The Archimedes srcew turbine (Archimedes scew turbine AST) has been implemented to convert hydroelectric energy since the 1990s. Many variables affect the performance of Archimedes screw turbines such as pitch ratio, immersion rate, water flow and turbine shaft angle. The purpose of this study was to determine the effect of the turbine shaft inclination angle (25-35o) on the rotation, current and voltage produced by the screw turbine. The screw turbine has a diameter of 260 mm with a shaft length of 1200 mm and a pitch distance of 200 mm. The flow rate of water is used at 0,0065 m3/s to rotate a low speed generator. The results showed that the higher the turbine shaft angle resulted in an increase in rotation, voltage and current produced. The optimum angle is obtained at a turbine angle of 35o which produces 2,058 Watts at 243 rpm.
