Penelitian ini menganalisis pengaruh suhu dan kelembapan terhadap fenomena flashover pada isolator polutan lumut di Koto Panjang, Payakumbuh. Analisa perhitungan dilakukan dengan variasi suhu dan kelembapan yang berbeda berdasarkan hasil eksperimen pada isolator polutan lumut untuk mengamati terjadinya flashover. Hasil penelitian menunjukkan nilai tegangan flashover tertinggi terjadi pada kelembaban 76.8% yaitu 334.1 kV Anderson dan 353 kV eksperimen, sedangkan yang terendah terjadi pada kelembaban 80.1% yaitu 330.3 kV dan 333 kV. Jadi semakin tinggi kelembaban maka tegangan flashover akan semakin rendah baik flashover perhitungan maupun flashover eksperimen. Sedangkan suhu mengalami kenaikan seiring meningkatnya nilai tegangan flashover. Nilai tegangan flashover tertinggi terjadi pada suhu 30.5°C yaitu 334.1 kV Anderson dan 353 kV eksperimen, Sedangkan yang terendah terjadi pada suhu 28.9°C yaitu 330.3kV dan 333kV. Jadi semakin tinggi suhu maka tegangan flashover akan semakin tinggi.

Abstract: The formulation of Islamic legal norms (fiqh) based on zhanni (speculative) evidence often leads to divergent interpretations among mujtahid scholars. These differences can confuse within the Muslim community regarding which legal opinion should be followed. This study aims to analyse the theoretical framework of al-mushawwibah and al-mukhaththiah within the discipline of ushul al-fiqh, particularly in the context of determining legal rulings derived from zhanni sources. Employing a qualitative descriptive approach and library research method, the study examines selected verses of the Qur’an, Prophetic traditions, and the classical as well as contemporary juristic opinions. The findings reveal that the al-mushawwibah theory affirms the validity of multiple legal conclusions as long as they are grounded in sound ijtihadic methodology. At the same time, al-Mukhaththiah asserts that only one ruling can be deemed correct, though other attempts still merit reward. The novelty of this research lies in its contextual application of classical epistemological theories to contemporary fiqh disputes, such as the differing opinions on whether bank interest constitutes riba. These insights contribute to the reinforcement of legal pluralism and encourage a moderate approach in navigating diverse ijtihad-based rulings within Islamic law.

Background: One of the problems that Manila duck farmers often face today is the high price of feed and unstable growth rates. This causes the body weight growth of Manila ducks to not be optimal and has an impact on the percentage of carcasses that are not as expected. Papaya leaves are one type of waste from agricultural businesses that can be used as additional feed by turning them into flour mixed into feed. Papaya leaf flour contains protein, calcium, and phosphorus and can increase the carcass productivity of Manila ducks. Purpose: This study aims to determine the effect of the addition of papaya leaf flour in feed on the carcass percentage of the chest and thighs of Manila ducks. Methods: This study used 40 manila ducks aged 6 weeks as material. The method used was a completely randomized design (CRD) consisting of 4 treatments and 5 replications. The treatment consisted of the addition of papaya leaf flour (PO 0%, P1 3%, P2 5%, and P3 7%). Results: The results showed that the addition of papaya leaf flour in feed had a very significant effect (P <0.01) on the percentage of carcasses of the breast and thighs of manila ducks. Conclusion: From the results of this study, it can be concluded that the addition of papaya leaf flour in feed up to 5% level can increase the percentage of carcasses of breast and thigh of manila ducks.

This study aims to analyze the impact of Effort Expectancy (EE) adapted from the Unified Theory of Acceptance and Use of Technology (UTAUT) and Cognitive Attitude (CA) from the Theory of Reasined Action (TRA) model on Willingness to Accept (WA) adapted from TAM on ChatGPT. By understanding the relationship between these factors, we can identify effective strategies to increase user acceptance of ChatGPT technology. The research method used is quantitative with multiple linear regression calculations in SPSS. This study obtained 50 respondents with a total of 10 variables but there were 3 main variables. With the final result, Effort Expectancy has no significant effect on Willingness to Accept while Cognitive Attitude has a significant effect on Willingness to Accept. This suggests that users’ perceptions of how easy or difficult it is to use ChatGPT do not influence their decision to accept and use the technology. In this context, users may feel that ease of use is not a major factor influencing their acceptance of ChatGPT. This means that users’ cognitive attitudes—including their beliefs, perceptions, and understanding of the technology—play an important role in their decision to accept and use ChatGPT.

Newton's Law is a basic concept in physics learning at the high school and college levels, but students' conceptual understanding of the concept is still weak. This study aims to analyze students' difficulties in the concept of Newton's Law by looking at the consistency of students' answers to isomorphic problems. The research method used quantitative research by means of a survey. The respondents were 118 students (58 high school students and 60 MAN students) who had taken the Newton's Law chapter. The research instruments were adapted from the Force Concept Inventory (FCI) and isomorphic multiple-choice question (IMCI) which were validated by two physics experts. The analysis technique uses isomorphic analysis by looking at the consistency of student answers to the concept of Newton's Law. Based on the consistency of the answers, three groups of students’ conceptual understanding were determined, namely the “Understanding” when students were consistently correct on three isomorphic items, “Moderately Understanding” if they were consistently correct on two isomorphic items, and “Not Understanding” if only one answer was correct or did not answer correctly on the isomorphic items. The study found that students' conceptual understanding on all isomorphic items was low. especially in Theme 5 which is about the concept of analyzing the relationship between force and the speed of motion of objects with 97.46% of students having difficulties, and Theme 3 with the concept of action-reaction on Newton's Third Law with 95.76% having difficulties. The recommendation for further research is to apply learning methods to overcome students' difficulties in Newton's LawKeywords: Conceptual understanding, newton’s law, Isomorphic question.DOI: http://dx.doi.org/10.23960/jpf.v12.n2.202402

The issue of dropout remains a serious challenge at the vocational high school (SMK) level, including at SMK Islam Nusantara. Over the past five years, the school has experienced a dropout rate of 20% of all enrolled students. This study aims to identify students at high risk of dropping out by applying the K-Means and C4.5 algorithms. The K-Means algorithm is used to cluster students based on factors such as academic performance, socioeconomic conditions, and the distance from home to school. Subsequently, the C4.5 algorithm is used to predict dropout risk based on the clustering results. The data used in this study were obtained directly from the Dapodik Data Center of SMK Islam Nusantara and include student data from the 2019 to 2024 academic years. The results indicate that socioeconomic factors, the distance from home to school, and academic performance significantly influence dropout risk. Students from low-income families and with poor academic performance were found to be at the highest risk of dropping out. This study makes a significant contribution to SMK Islam Nusantara by developing an early warning system that can help identify students at risk of dropping out. With more targeted interventions, such as academic counseling and socioeconomic support, it is expected that the dropout rate can be significantly reduced. Additionally, this predictive model can be applied to other vocational schools with similar conditions to improve the overall quality of vocational education.
