Abstract

Learning difficulties are conditions where students experience difficulties in understanding subject matter, so that the learning outcomes obtained do not match their abilities. This study aims to determine the factors causing learning difficulties in Natural and Social Sciences (IPAS) for fourth-grade students at SDN 40 Cakranegara. Data collection methods were carried out using questionnaires and interviews. The data analysis technique used was Miles and Huberman with analysis components including data reduction, data presentation, and conclusion drawing. The results showed that learning difficulties in IPAS are influenced by internal and external factors. Based on the questionnaire results, the contribution of internal factors includes learning attitude (15.70%), motivation (23.24%), and interest (21.66%), while external factors consist of family (22.74%) and school (17.03%). In detail, from internal factors, students' learning attitudes are still low, especially in the indicators of self-confidence and feelings; learning interest is low in the indicators of attraction and feeling of pleasure; and motivation is not yet optimal in the indicators of initiative and commitment. From external factors, the school's social environment is not fully supportive because students lack encouragement from peers, while from the family side, an unsupportive home atmosphere, unsupportive parenting styles, and economic limitations were found. The learning difficulties in IPAS among fourth-grade students are the result of the interaction between weak internal factors and lack of external support, thus requiring synergy between teachers, schools, and parents to help students overcome learning difficulties more optimally.

Abstract

This study aims to determine the effect of differentiated instruction on student learning outcomes in the subject of Natural and Social Sciences (IPAS) for Grade IV at SD Negeri 247 Palembang. The background of this research is based on the low student achievement in the topic "Me and My Needs" and the suboptimal application of instructional strategies that address individual differences. Differentiated instruction is an approach that adapts the process, content, and product of learning based on students’ readiness, interests, and learning profiles. This study used a quantitative method with a quasi-experimental design, specifically the Nonequivalent Control Group Design. The sample consisted of 60 students selected through simple random sampling and divided into two groups: the experimental class (using differentiated instruction) and the control class (using conventional instruction). Data were collected through validated pretest and posttest essay-type questions. Data analysis was conducted using normality tests, homogeneity tests, and an Independent Sample T-Test with the help of SPSS version 26. The results showed that the average score of students in the experimental class increased from 40.67 to 71.27, while in the control class it increased from 28.8 to 55.00. The t-test showed a significance value of 0.001 < 0.05, indicating a significant difference between the two groups. Thus, it can be concluded that differentiated instruction has a positive and significant effect on student learning outcomes. This study recommends that teachers implement more differentiated instruction strategies to improve the quality of learning in elementary schools.

Abstract

This research is motivated by the low independence of elementary school students in mathematics, especially fractions, due to conventional methods and the lack of innovative teaching materials. The objective is to develop and test the effectiveness of Applied Behavior Analysis (ABA)-based mathematics teaching materials to improve student independence. Using the ADDIE development model, this research began with an analysis of student needs and the curriculum. The design stage included designing a fraction addition module, including visual elements. Development involved validation by material and media experts, as well as revisions. Implementation was carried out through a trial in grade V of SD Negeri 1 Moyot, with data from response questionnaires and learning outcome tests. Product evaluation showed that this teaching material was very feasible (media experts 98%, material experts 80%). Student responses were positive ("Good" 66.48%), and learning outcomes improved ("Good" 75.64%), with classical completeness of 76%. The implication is that ABA teaching materials are effective in improving student independence and mathematics learning outcomes, and serve as a reference for the development of innovative teaching materials

Abstract

Solar cells are devices composed of solar panels that convert light into electrical energy. Conventionally, energy is primarily derived from fossil fuels, which are non-renewable resources. Consequently, many researchers have sought alternative sources of energy. One such innovation is the Dye-Sensitized Solar Cell (DSSC). This study aims to investigate the effect of Antigonon leptopus flower dye as an active material in Dye-Sensitized Solar Cells (DSSC). The absorbance testing was conducted using a UV-Visible Spectrophotometer (1601 PC), while current and voltage (I–V) measurements were carried out using a Keithley instrument. The results showed that the natural dye extracted from the leaves of Antigonon leptopus exhibited an absorbance spectrum in the range of 200–800 nm. These findings suggest that Antigonon leptopus has potential as a natural sensitizer material for application in Dye-Sensitized Solar Cells (DSSC).
