Abstract

Research has been carried out on the synthesis of river sand-based nanosilica magnetic material to improve water quality by utilizing iron sand taken from four rivers in the Lombok island region as a natural material for the water filtration process, this study aims to determine whether the iron sand nanosilica magnetic material able to improve the quality of well water or not. 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.

Abstract

21st-century learning integrates knowledge, attitudes, and skills with mastery of technology. One solution for the learning demands of the 21st century is to apply a cooperative learning model, especially in physics subjects. Researchers used the methodization method in this study with 20 national article sources. The analysis results are reviewed based on the types of cooperative models, grade levels and physics materials contained in the article. Based on the average effect size, the influence of collaborative learning on aspects of students' physical knowledge was obtained in terms of the three groupings in the high category. It states that cooperative learning models have a very effective influence on physics lessons.

Abstract

This study aims to describe students’ problem-solving abilities and percentages in solving science (physics) problems in Work materials and simple aircraft class VIII MTsN 2 Trenggalek. This research uses a qualitative approach with a descriptive type of research. The data collection techniques used are tests and interviews. The data analysis includes 3 stages: data reduction, data presentation, and conclusion. The results of the research on students’ problem-solving ability are based on the stages of the Polya model: (1) High-ability students have been able to meet all indicators of the Polya problem-solving stages by 82.99% in the very high category. (2) Moderately capable students can already meet all indicators of the problem-solving stages for Work questions. However, they are still less capable in simple aircraft questions, with a percentage of 64.58% being in the high category. (3) Low-ability students have not been able to meet all the indicators of the problem-solving stage, with 15.42% being in the deficient category. Students cannot understand problems, draw plans, execute plans, and look back. The reason is that students do not understand the material clearly, which impacts their problem-solving ability. The research showed that students’ problem-solving ability is in a suitable category with a percentage of 54.33%. The stage of understanding the problem includes the stages the student can achieve. Students are still underprivileged in the following three stages: drawing up a plan, implementing a plan, and looking back. Students still have difficulty determining the right strategy to solve problems in Work and simple aircraft questions.

Abstract

The purpose of this study was to compare the application of the think pair share (TPS) learning method and conventional methods to student learning outcomes in physics learning. The type of research used is quasi-experimental (Quasy Experimental Design). The subjects in this study were two classes, namely 24 X MIPA 1 students as an experimental class using the Think Pair Share (TPS) learning method and 24 X MIPA 2 students as a control class using conventional methods. The sampling technique used purposive sampling. Data collection techniques using documentation, tests, and observations. The data analysis technique used in this study was the Independent Sample Test (t-test) with a significance level of 5%. Before the data were analyzed, a prerequisite test for normality analysis was carried out. The results showed that there were differences in the learning outcomes of students who were taught using the TPS method with conventional methods in physics subjects. Where the average post-test score for the experimental class was 72.45, higher than the control class, which was 51.54. These results indicate that student learning outcomes in the experimental class experienced a significant increase compared to the control class. The results of calculating the gain score for the experimental class obtained an average pre-test of 54.04 and a post-test of 72.45 so a Gain of 0.40 was obtained in the moderate category. Whereas in the control class, the average pre-test was 49.87 and the post-test was 51.54 so a gain of 0.03 was obtained in the low category. This shows that learning using the TPS method is better than using conventional methods.

Abstract

This paper focuses on the characteristics of K0.5Na0.5VO3 (KNV) and SiO2 when added to Mg0.8Zn0.2TiO3 (MZT) material to reduce the sintering temperature. Initially, a single phase of Mg0.8Zn0.2TiO3 (MZT) was synthesized using the conventional solid-state reaction method at 850°C for 4 hours. Subsequently, (K0.5Na0.5)VO3 was formed as a single phase at a temperature of 500°C for 2 hours. The reduction of MZT sintering temperature was then carried out by adding K0.5Na0.5VO3 and SiO2 and sintering at 950°C for 4 hours. Adding K0.5Na0.5VO3 and SiO2 resulted in a maximum density value of 2.76 g/cc and an average grain size of 3 µm based on scanning electron microscopy (SEM) analysis. The optimal composition was found to be 0.7MZT-0.25KNV-0.05SiO2. X-ray diffraction (XRD) characterization using the Rietveld method revealed the presence of three phases: (Mg/Zn)TiO3, (K/Na)VO3, and MgTi2O5. Based on the results, it can be concluded that the (K/Na)VO3-SiO2 material can be effectively utilized as a sintering agent for (Mg/Zn)TiO3, reducing the sintering temperature of the material.

Abstract

Research on hemp fiber composites with epoxy resin matrix and lead acetate as an alternative material for X-ray radiation shielding has been conducted to determine the optimal composition of radiation shielding samples made from hemp fiber, epoxy resin, and lead acetate. The method used to make composite samples with six different designs, namely using a ratio of 4 gams, eight gams, and 12 gams of hemp fiber to 80 gams and 160 gams of resin. The lead acetate used in each composition is 2.5 gams. This study carried out three measurement processes: density, attenuation, and absorption. Density measurements were carried out by measuring the volume and mass of the sample. In contrast, attenuation and absorption measurements were carried out using a mobile X-ray aircraft with a Piranha multi-X-ray meter detector. In the three measures, the highest value was obtained in composition VI, namely with 12 gams of hemp fiber, 160 gams of epoxy resin, 80 gams of catalyst, and 2.5 gams of lead astate. The density value obtained was 1.120 g/cm3. The sample with this composition can absorb 71.22% (1.24580 cm-1) of radiation at 40 kV, absorb 66.91% (1.10621 cm-1) at 60 kV and 60.22% (0.92191 cm-1) of radiation absorbed at 81 kV voltage. Therefore, it can be concluded that the higher resin and hemp used, the more excellent density value obtained—the geater density of the sample, the geater value of attenuation and absorption.
