Abstract

This research examines the implementation of a humanistic approach-based curriculum at Madrasah Aliyah (MA) Muallimat Muhammadiyah, founded on the personal education theories of John Dewey and J.J. Rousseau. Using qualitative methods through interviews and observations, this study analyzes the application of the humanistic approach in the madrasah curriculum. The research findings reveal that the curriculum implementation not only focuses on academic aspects but also encompasses students' moral and social development through various integrative learning activities. The research identifies three main findings: First, the integration of academic subjects between religious education and science that produces comprehensive understanding for students. Second, social reconstruction manifested through students' active involvement in identifying and solving social problems in their environment. Third, the effective utilization of technology to enrich the learning process and develop students' digital capabilities. The humanistic approach in the curriculum proves effective in developing students holistically. This is evident from the improvement in academic achievement balanced with mature personality development and good social skills. These findings indicate that the humanistic approach can serve as an ideal curriculum development model for Islamic educational institutions in preparing a generation that is not only intellectually intelligent but also possesses strong character.

Abstract

Abstract : This research is motivated by the problem of Realization of Separated Regional Management Wealth Results (RSRMWR) in East Java which has experienced fluctuations over the last three year period. Because the decline could result from less than optimal management of the business entity, it is estimated that the Regional Owned Enterprises (ROE) sector will become a business entity that always suffers losses and burdens the Regional Revenue and Expenditure Budget (RREB). It is expected to contribute to Regional Original Income (ROI), but in the field more grants flow from the RREB to ROE, while a small share of profits from ROE is set aside for ROI. The research aims to determine and analyze the effectiveness and contribution of RSRMWR to ROI. The research approach uses quantitative causality. The type of data used in this research is secondary data sourced from djpk.kemenkeu.go.id, the analysis method used is multiple linear regression analysis. The results of this research show that partially and simultaneously the effectiveness of RSRMWR and the contribution of RSRMWR do not have a significant effect on the ROI of Regencies and Cities in East Java in 2021-2023.  Abstrak : Penelitian ini dilatarbelakangi oleh permasalahan realisasi Hasil Kekayaan Pengelolaan Daerah Yang Dipisahkan (HPKDYD) di Jawa Timur yang mengalami fluktuasi selama periode tiga tahun terakhir.

Penelitian bertujuan untuk mengetahui dan menganalisis efektivitas dan kontribusi HPKDYD terhadap PAD. Pendekatan penelitian menggunakan kuantitatif kausalitas. Jenis data yang digunakan dalam penelitian ini data sekunder bersumber djpk.kemenkeu.go.id, metode analisis yang digunakan adalah analisis regresi linier berganda. Hasil penelitian ini menunjukkan bahwa secara parsial dan simultan efektivitas HPKDYD dan kontribusi HPKDYD tidak berpengaruh signifikan terhadap PAD Kabupaten dan Kota di Jawa Timur tahun 2021-2023.
