Abstract

This study aims to determine the influence of the Inquiry-Based Learning model on students' scientific ability in Rotational Dynamics of a Rigid Bodies. This influence is seen from whether or not students can achieve the criteria of completeness by mastering three PISA (Program for International Student Assessment) indicators in 10 items on the test consisting of two questions to identify scientific problems, five question to explain phenomena scientifically, and three questions to interpret data and scientific evidence. The research method applied is the experimental method and uses the One Group Pretest-Posttest Design as a research design involving 4 classes, where 1 class acts as the experimental class and 3 classes as the replication class. Based on the statistical results of the t-test to test the research hypothesis, the t-count value for each sample class is greater than the t-table value. This shows that the use of the Inquiry-Based Learning learning model has an effect on students' scientific literacy abilities in the rotational dynamics of a rigid bodies

Abstract

Unfortunately, there has been a great worry about clean and healthy water for human consumption lately. Even though 2/3 of the earth's surface is covered by water, the access to safe water is only concentrated in certain areas. In Indonesia, water scarcity is increasing each year. Recent data on freshwater resources possessed by all countries in the world shows that Indonesia is ranked 51st with the highest risk of water scarcity (40-80%). There are several methods to gain access to safe water, one of which is the use of distillation equipment. This research aims to produce a design of freshwater distillation equipment from seawater by utilizing solar radiation towards the quantity of freshwater and to determine the quality of freshwater from the results of distillation which include water pH, salinity, and TDS tests. The research method is done by heating sea water in the distillation equipment using solar radiation. Findings reveal that the average solar intensity of 1608.25 (lux) and the ambient temperature of 38.5 °C can produce an average volume of freshwater of 336.75 ml per day from the incoming seawater volume of 2000 ml. The water quality produced has a pH of 6.5, a salinity of 0.2 ppt, and a TDS of 152 mg/L.

This study aims to see the effect of the Contextual teaching and learning model on science learning for disabled children. The learning devices use the Contextual Teaching and Learning (CTL) approach and the PBI (Problem Based Instruction) learning model for disabled children in class X SMA which consists of the syllabus , RPP, LKPD, teaching materials and competency assessment. This research is a type of research and development using the ADDIE development model which consists of 5 stages, namely the Analysis, Design, Development, Implementation, and Evaluation stages. This study uses data collection consisting of expert validation, observation, interviews and tests. Based on the results of the study, it was found that the learning tools that had been developed met the appropriate criteria and could be used with minor revisions. Decent learning tools were obtained from validation results by 3 validators who were test lecturers, while the effectiveness of the devices was obtained from several indicators, namely learning implementation with an average of 93.93%, student activity with an average of 86.9%. As well as positive responses from teachers and students obtained by interview.

Abstract

Landslides are one of the geological disasters that often occur in Indonesia. North Gorontalo is an area where landslides occur every year. Based on data from the 2022 Badan Penanggulangan Bencana Daerah (BPBD), in the last year, there were 8 landslides. Landslides can occur due to several factors, namely; human factors and natural factors. In principle, landslides occur when the restraining force is less than the driving force. In this study a landslide simulation will be carried out using a simulation model made on a lab scale, the size of the simulation model is 40 cm x 30 cm x 25 cm. The simulation was carried out using soil samples taken at the research location. Variables that were observed during the simulation were the effect of the slope angle (o) on the exiting water (ml), the water infiltration time (t), and the effect of the slope (o) on the depth of the slip plane (cm). The soil taken from the research location will be subjected to a sieving analysis test with a hydrometer test to determine the texture class of the soil. From the soil texture test results, some of the research locations have a sand-gravel type of texture. The simulation test carried out also obtained the result that the slope of the slope greatly influences the water infiltration time with the depth of the slip plane. The greater the angle of the slope of the sled that is carried out, the results of the variable being measured will also be directly proportional.

This research is experimental, with the research design being a one-group pretest-posttest design. The population in this study was all class VIII of SMP Negeri 8 Paguyaman for the 2023/2024 academic year. Research data was collected using test techniques. Then, the data was analyzed using descriptive and inferential statistics, including normality tests, hypothesis tests, and n-gain analysis. The average score for all sample classes for class VIII students is greater than the minimum completion criteria (MCC), as shown by the average score for the experimental class of 81.97, replication class 1 of 80.91, and replication class 2 of 80.15, compared to the MCC of 75. Based on the course results, the average normalized gain obtained by the experimental class was 0.69, replication class 1 was 0.68, and replication class 2 was 0.68, meaning that all sample classes are in the medium category. Thus, the PjBL model based on local Gorontalo cultural values ​​has a significant effect on student learning outcomes in simple aircraft concepts

Abstract

Sugarcane bagasse is waste from the sugar industry which has the potential to be an efficient fuel for producing electricity by converting heat energy into electrical energy using a Thermoelectric Generator (TEG). TEG can be optimized to burn sugarcane bagasse as an alternative energy source in Indonesia. This research uses series and parallel configurations to test the optimal TEG configuration to increase energy conversion efficiency. The research results revealed that supercapacitors' parallel configuration produced the highest power in the 66th minute at 0.26 W. In comparison, the series configuration with supercapacitors produced 0.21 W of power in the 63rd minute. For the parallel configuration without supercapacitors, the energy produced reaches 0.20 W in the 69th minute, and the series configuration without supercapacitors produces 0.19 W in the 63rd minute. The parallel configuration shows more optimal performance than the series configuration, making it a promising solution in diversifying energy sources, especially in supporting efforts to utilize agricultural waste sustainably. Optimization of the thermoelectric generator configuration for burning sugarcane bagasse can be used as an alternative energy source.
