Analysis of Teachers' Needs in Renewable Energy Learning Programs Using SSI Integrated with PjBL-STEM to Enhance Collaborative Problem-Solving and Entrepreneurial Skills
No full textThis preliminary study explores the needs of teachers and students in physics learning, focusing on renewable energy topics. Using a survey method, data were collected from 24 high school physics teachers in Lampung Province via Google Forms. The findings were analyzed to identify educational gaps and propose solutions. Results reveal a pressing need for learning programs that enhance Collaborative Problem-Solving and Entrepreneurial Skills. While 83.30% of teachers reported integrating Project-Based Learning STEM (PjBL-STEM) into their teaching, only 23.50% of worksheets used were PjBL-STEM-based, and just 26.70% were self-created. Teachers faced challenges such as limited time and difficulty initiating development. Additionally, only 54.20% of teachers were familiar with the Sustainable Development Goals (SDGs). The study also highlights gaps in skill assessment, with 75% of teachers not evaluating Collaborative Problem-Solving Skills and 87.50% not assessing Entrepreneurial Skills. Despite using teaching media and worksheets, these gaps suggest a need for more robust tools and methods.The findings underscore the importance of developing renewable energy learning programs integrated with PjBL-STEM. Such programs can address existing challenges, promote SDG awareness, and equip students with critical skills for collaboration and entrepreneurship in the context of physics education.Penelitian ini merupakan studi pendahuluan yang bertujuan untuk menentukan kebutuhan guru dan siswa dalam proses pembelajaran, khususnya dalam konteks mata pelajaran fisika yang terkait dengan energi terbarukan.

Hal tersebut dikarenakan guru terkadang bingung memulai awalnya dan belum ada waktu yang cukup untuk mengerjakannya. Selanjutnya sebanyak 75% guru belum mengukur ketarampilan Collaborative Problem Solving dan sebanyak 87,5% guru belum mengukur Enterpreneurial Skill alam proses pembelajaran. Oleh karena itu, pengembangan program pembelajaran energi terbarukan yang terintegrasi dengan PjBL-STEM menjadi sangat penting
Penyakit Hirschsprung di Indonesia: Faktor Potensial yang Berkontribusi dan Analisis Silsilah
No full textHirschsprung’s disease (HD) has a complex origin involving genetic factors. While HD cases have been documented in Indonesia, the genetic inheritance is unexplored. This study aims to update HD in Indonesia, determine the inheritance pattern through pedigree analysis, and identify the non-genetic factors contributing to HD, including parental demographics and maternal aspects. A cross-sectional survey was conducted with 87 respondents across Indonesia. The results revealed a male-to-female incidence ratio of 1.90:1, with the ultra-short segment being the most common type (75.86%), and familial cases accounted for 8%. Seventeen patients exhibited other congenital abnormalities, with pneumonia, redundant colon, and cardiac defect as the highest cases. Over 70% of the parents were aged 20-35 and had relatively high education and income levels. Notably, nearly half of the mothers experienced food aversion in the first trimester (n=38) and frequently consumed fast or instant food during pregnancy (n=33). The study confirmed that HD follows an autosomal recessive inheritance pattern. These findings emphasize the role of genetic inheritance in incidents of HD, which is valuable for developing early detection strategies and providing genetic counseling for at-risk families. Maternal lifestyle factors may play a role in the development of HD, which needs further investigation
Analysis of Assessment Instrument Needs to Measure Students Critical Thinking Skills and Self-Efficacy in Physics Learning
No full textThis research is a preliminary study that aims to determine the needs of teachers and students in the learning process, especially in the material of particle motion dynamics. The research method chosen was a survey, which was conducted on 20 physics teachers and 30 high school students in the MIPA field in Lampung Province using Google Form. The collected data were then curated and analyzed to identify and address educational needs. The results of the data analysis showed a demand for assessment instruments that can measure critical thinking skills and self-efficacy in physics learning. According to the survey, 45% of teachers never assess critical thinking skills and 60% of teachers never assess self-efficacy. Teachers do not apply because of the lack of examples or instruments owned to assess critical thinking skills and self-efficacy. Teachers also do not have assessment instruments that are easy, practical, and appropriate during the learning process. Physics learning assessment at school has not optimized critical thinking skills well, so critical thinking skills are still low, and self-efficacy is still an obstacle. Therefore, the development of assessment instruments to measure critical thinking skills and student self-efficacy in physics learning is very important

Investigation and Analysis of Fuzzy Logic Controller Method on DC-DC Buck-Boost Converter
No full textThis study evaluates the performance of PID, Mamdani FLC, and Sugeno FLC controllers on a DC-DC Buck-Boost Converter to determine their suitability for various control applications. The Buck-Boost Converter, operating in conventional configuration, was modeled using MATLAB/Simulink with parameters: input voltage (12 V), output voltage (24 V), resistor (6.5 Ω), capacitor (1.5 µF), and inductor (10 µH). The converter's switching frequency was set at 20 kHz to ensure stability under varying load and input conditions. PID control was implemented using the Ziegler-Nichols tuning method, while fuzzy controllers utilized Gaussian membership functions and 3×3 fuzzy rule bases. Mamdani employed the centroid defuzzification method, whereas Sugeno used weighted average defuzzification. The simulation tested performance metrics, including rise time, overshoot, output stability, and voltage ripple, under conditions of load and input voltage variations. Results show that PID achieved the fastest rise time (72.452 ms) but exhibited higher sensitivity to input changes. Sugeno provided the most stable output with minimal ripple, while Mamdani demonstrated greater adaptability but less stability compared to Sugeno. Statistical analysis confirmed significant differences in rise time but no differences in overshoot across methods. These findings highlight the strengths of each method, with Sugeno being optimal for stability and precision, PID for fast response, and Mamdani for complex fuzzy logic applications
