Abstract

Science learning, especially in physics, is an abstract concept and difficult for students to understand. In addition, there is also a need for a bridge that can connect physics concepts with life in the student's daily environment. Therefore, technological innovations are needed in learning such as developing an electronic practicum guidebook for solar cells, Arduino IoT systems based on automatic feed thrower prototypes to develop students' science process skills. This study used a 4D model. The subjects of this study were 6th semester S1 Science students totaling 52 students. The data generation instrument uses questionnaires and implementation observation sheets. Data analysis techniques use qualitative and qualitative. Based on the results of the validation that has been carried out, the practicum guide that has been prepared as a whole has eligibility criteria that are very feasible to use, with a percentage of 92.25%, while the students' science process skills in the solar cell electronic practicum guide for the Arduino IoT system based on the prototype of this automatic feed thrower get an average of 92% with a very good category so that it can be considered that students are good at understanding and Work on the basis of practicum guidelines developed.

Abstract

The purpose of this study is to make snake fruit briquette charcoal mixed with goat dung an alternative energy source that supports environmentally friendly technology. The samples used were snake fruit and goat dung as charcoal and tapioca flour as an adhesive. Each sample has 200 grams of charcoal and 30 grams of adhesive. The percentage of charcoal is 50% snake fruit bark charcoal and 50% goat dung charcoal. Snake fruit briquettes and goat dung are divided into 3 groups: A1 (87% charcoal: 13% adhesive), A2 (77% charcoal: 23% adhesive), and A3 (97% charcoal: 3% adhesive). In 3 samples tested with the percentage of charcoal flour to tapioca flour, the first one was produced in sample A1 (87%: 13%), which produced a moisture content of 9.87%, an ash content of 36.75%, and a calorific content of 5899 kcal/kg. The A2 sample (77%:23%) yielded a moisture content of 11.44%, an ash content of 32.13%, and a calorific content of 5634 kcal/kg. The A3 sample yielded a moisture content of 8.93%, an ash content of 41.38%, and a calorific content of 6339 kcal/kg.  This study concludes that the best calorific value in the A3 sample is 97% charcoal briquettes with 3% adhesive, with a calorific value of 6339 cal/kg.

Abstract

Knowledge continues to evolve, requiring teachers to innovate, particularly in implementing the Kurikulum Merdeka (Independent Curriculum). Field observations indicate that many schools still struggle with its implementation, as they must tailor learning to students' individual characteristics. SMPN 03 Lebong in Bengkulu Province is one such school facing these challenges. Given these issues, an alternative solution is needed to support the independent implementation of the Kurikulum Merdeka. One possible approach is to provide training for teachers at SMPN 03 Lebong on designing learning activities and practical worksheets based on the Prediction, Observation, and Explanation (POE) model. This training follows the I-CARE design, which consists of five stages: Introduction, Connection, Application, Reflection, and Extension. As a result, teachers successfully developed six learning designs and practical guides based on the POE model, utilizing available tools and materials from their surroundings. This initiative enhances student-centered learning, aligning with the objectives of the Kurikulum Merdeka.

Abstract

One of the heavy metals that can pollute waters is the heavy metal chromium (Cr). Chromium has many important roles in life. Chromium material is widely used by humans for various purposes, especially in the industrial world. However, the large number of uses of chromium in the industrial world and the waste it generates can have a negative impact on the environment and human health. One way to deal with chromium pollution is by analyzing the presence of chromium in waters. The aim of this research is to analyze the presence of chromium using a simple, effective, economical and accurate method, namely the biosynthesis of gold nanoparticles using samples of starfruit (Averrhoa bilimbi) as a bioreductor rich in ascorbic acid, with a colorimetric method, namely a method based on the aggregation of gold nanoparticles with ascorbic acid from starfruit, which causes a shift in plasmons and causes color changes that can be seen by the eye. Based on the analysis results, data was obtained that gold nanoparticles synthesized from the starfruit bioreductor can detect chromium with a concentration of 10 ppm with optimum conditions at pH 5, temperature 75oC, optimum incubation time of 5 minutes and gold nanoparticles are selective and sensitive for detecting chromium.

Abstract

This study aimed to identify the antioxidant content in turmeric leaf extract using the DPPH (2,2-diphenyl-1-picrylhydrazyl) method. The tested concentrations include 200 ppm, 150 ppm, 100 ppm, 50 ppm, 25 ppm, and 12.5 ppm, with absorbance measurements conducted using a UV-Vis Spectrophotometer. Data were analyzed by calculating the percentage of antioxidant activity based on the absorbance values of each concentration. Subsequently, the IC50 value was determined using a nonlinear regression equation, representing the relationship between the logarithm of concentration and the percentage of antioxidant activity (inhibition). The results of the study showed that the IC50 value of turmeric leaf extract was 61.88. The conclusion of this study indicates that turmeric leaf extract exhibits strong antioxidant activity. Keywords: Antioxidant, Turmeric Leaves, DPPH, IC50

Abstract

This study aims to determine students' responses after implementing biology learning on the pH scale material using the Physics Education Technology (PhET) Simulation. The method used was a survey by distributing questionnaires to 15 Biology Education students at Universitas PGRI Silampari, Lubuklinggau City, South Sumatra Province, who had studied pH scale measurement material using the PhET Simulation. The questionnaire included several indicators: students' interest, benefits, display, and usability of PhET, divided into six statements. The results showed that 86.7% of students strongly agreed that learning using PhET was very interesting, 53.3% of students strongly agreed that PhET motivated and facilitated learning the pH scale, 60% of students strongly agreed that PhET made it easier to understand the pH scale material, and 53.3% of students strongly agreed that the PhET Simulation was easy to understand and its animation design and text met students' needs. In conclusion, the PhET Simulation is very engaging, motivates learning, facilitates material learning, eases material understanding, is easy to use, and its animation design and text align with students' needs. Keywords: PhET, Potential of Hydrogen, Student Response.
