Abstract

Terdapat beberapa sisi negatif dari penggunaan motor induksi , yaitu timbulnya harmonisa yang dapat mengurangi kualitas daya listrik. Selain motor listrik, penggunaan Lampu konvensional atau lampu menggunakan ballast trafo juga turut ambil bagian menjadi penyebab turunnya kualitas daya. Penelitian bertujuan mengembangan solusi yang mampu mengurangi gangguan kegagalan fungsi atau degradasi peralatan dan perangkat yang lebih sensitif dan kerugian tambahan berupa pemanasan berlebih yang menyebabkan pengurangan umur rata-rata peralatan, minimalisasi terjadinya penurunan power faktor dan timbulnya harmonisa pada pemanfaatan energi listrik. Metode yang digunakan adalah eksperimen. Untuk beban non linier seperti lampu TL menyebabkan penurunan nilai faktor daya, beda fasa tegangan dan arusnya sebesar 69,8°, untuk beban linier lampu pijar beda fasa tegangan dan arus 0°. Untuk lampu TL nilai faktor daya terukur 0.34, lampu pijar 1.0 dan lampu Led tidak ada besaran nilai faktor daya yang terukur. Effisiensi untuk beban lampu TL 0.24%. Karena permasalahan itu, paper ini menampilkan rancangan Filter aktif Pararel yang secara prinsip akan menginjeksikan arus kompensasi yang besarnya sama dengan arus distorsi pengaruh harmonisa.

Abstract

This study examines the dynamics of personal adjustment in Quranic memorization students using a mixed methods approach, combining quantitative field analysis as primary data and meta-analysis as secondary data. The field study involved 515 students from two Indonesian Islamic boarding schools: Pesantren Tahfizh Daarul Qur'an and Yayasan Islamic Centre Sumatera Utara. The meta-analysis included 30 studies (N = 4,827) from international databases. The quantitative analysis showed a high level of personal adjustment among students (M = 3.66, SD = 0.52), with the highest score on acting objectively according to one's conditions and potential (M = 3.85, SD = 0.48). Regression analysis revealed that self-acceptance significantly predicted overall personal adjustment (β = 0.42, p < .001). The meta-analysis confirmed a positive relationship between self-acceptance and personal adjustment (r = 0.53, 95% CI [0.47, 0.59]). Moderator analysis indicated a stronger effect for female students (r = 0.58) than males (r = 0.49). These findings extend the research of Ahmad et al. (2022) and Rahma (2023) by identifying unique factors influencing personal adjustment of Quranic memorization students, such as memorization intensity (β = 0.31, p < .01) and social support in Quranic boarding schools (β = 0.28, p < .01). Additionally, the integration of primary and secondary data provides a comprehensive understanding of the dynamics of personal adjustment in Quranic memorization students, emphasizing the importance of evidence-based interventions to enhance the psychological well-being of these students.

Abstract

Using a mixed-method approach, This study examines emotional support for Quranic memorization students (santri tahfidz) in Islamic boarding schools (pesantren). Quantitative analysis of 515 santri tahfidz revealed high levels of emotional support (M = 3.74, SD = 0.68) with two primary dimensions: reliable relationships (74.96%) and trusted guidance (75.17%). Multiple regression analysis uncovered a significant relationship between emotional support and Quranic memorization achievement (β = 0.42, p < .001, R² = 0.18). A meta-analysis of 28 studies (N = 3,627) confirmed a positive correlation between emotional support and students' psychological well-being (r = 0.39, 95% CI [0.34, 0.44]). MANOVA results indicated significant differences in santri tahfidz's perceptions of emotional support based on gender (Wilks' λ = .97, F(2, 512) = 7.85, p < .001, partial η² = .03) and age (Wilks' λ = .95, F(4, 1022) = 6.73, p < .001, partial η² = .03). These findings extend previous research by Hasfi (2018) and Vista (2018) by identifying the specific roles of teacher support (β = 0.31, p < .01) and peer support (β = 0.28, p < .01) in enhancing student resilience. Furthermore, this study contributes to a more comprehensive understanding of emotional support dynamics in pesantren tahfidz education, integrating Bronfenbrenner's (1979) ecological perspective and Deci and Ryan's (2000) self-determination theory. Finally in a practical context, the researcher evaluates this study has implications for the development of more structured and efficient emotional support intervention programs in tahfidz pesantren.

Abstract

This study aims to examine the theoritical model of the effect of teacher self-efficacy and teacher perceptions of the competence of Madrasah Principals on the performance of Inclusive Madrasah teachers with job satisfaction as a mediator. The population in this study were teachers of Madrasah Aliyah (MA), Madrasah Tsanawiyah (MTs), Madrasah Ibtidaiyah (MI) and Raudhatul Athfal (RA) both public and private in the Java Island region which again amounted to 2,184 people. The sampling technique used is purposive sampling which is a type of non-probability sampling, 358 respondents who participated, only 19 had to be dropped because they did not meet the research criteria, so that the total respondents analyzed were 339 people. The measuring instruments used in this study include Teacher Performance Assessment (PKG), Madrasah Principal Competency Instruments, Norwegian Teacher Self-Efficacy Scale (NTSES) and The Teacher Job Satisfaction Scale (TJJS-9). Data analysis using Structural Equating Modeling (SEM) with Lisrel 8.8 software. The results of the Structural Equating Modeling (SEM) analysis found that the theoretical model of the influence of self-efficacy and teacher perceptions of the competence of the madrasah principal on the performance of Madrasah Inclusion teachers with job satisfaction as a mediator fit with empirical data. The results showed that only the personality and managerial competence of the Madrasah Principal had a direct effect on teacher satisfaction and performance and an indirect effect on teacher performance through job satisfaction, apart from the three dimensions of teacher self-efficacy did not affect teacher performance directly through job satisfaction. Keywords: teacher performance, self-efficacy, competency of inclusive Madrasah Principals, quality of Indonesian madrasas, job satisfaction
