Abstract

Quercetin was a flavonoid compound that was found in Annona muricata L. leaves. The UV Spectrophotometric method was used to determine quercetin from Annona muricata in liquid. The degradation was determined by selectivity, linearity, accuracy, precision, LOD, and LOQ. Selectivity showed that spectra had maximum absorbance at λ 374 nm. Good linearity was shown by y = 0,07368x - 0,01937 (r = 0,9984; p<0,05). The precision of standard quercetin in a concentration of 6,4 ppm showed a relative standard deviation (RSD) of 0,19%. LOD and LOQ of standard quercetin were 0,0240 µg/ml and 0,0801 µg/ml, and the accuracy was 91,867±7,59%. Determination of quercetin in Annona muricata leaf extract showed a concentration of 12,62±3,29% and (263,96 ± 6,69) mg in 10 ml liquid.Keywords: Quercetin, Annona Muricata L, UV Spectrophotometry, Method of Validation

Abstract

Micro-entrepreneurship in the property sector, particularly in rental shop-house (ruko) businesses, represents a promising strategy for fostering asset-based economic independence. However, limited research has explored female entrepreneurship practices through the lens of Islamic values, especially among MSME actors in semi-urban areas. This study aims to analyze the practice of Islamic edupreneurship in a ruko rental business managed by Ibu Sunaryati in Inderapura. A qualitative approach was employed using an exploratory case study design. Data were collected through in-depth interviews with the main entrepreneur, tenants, and community figures; participatory observation of business activities; and documentation of legal aspects such as lease contracts and building certificates. Thematic analysis was conducted using the Integrated Islamic Entrepreneurship Model (IIEM), which is grounded in three pillars: asset Islamization, entrepreneurial education values, and communal barakah (blessing). The findings reveal that this ruko rental business functions not only as a source of passive income but also embodies Islamic values such as ikhlas (sincerity), amanah (responsibility), and barakah in its daily operations. Business success is supported by a modular strategy, the application of sharia-compliant contracts (akad), and relationship management rooted in akhlaqul karimah (noble character). The study concludes that Islamic edupreneurship holds strong potential as an adaptive and sustainable model for micro-entrepreneurship. Its implications suggest that this model can be replicated by female MSME actors as a spiritually grounded approach to economic empowerment and asset-based prosperity.

Abstract

Teacher professionalism in the era of educational transformation and Society 5.0 faces epistemological challenges that are not only related to mastery of pedagogical and technological competencies, but also require the strengthening of moral and spiritual dimensions as the foundation of professionalism. This study aims to reconstruct Educational Science and Profession in order to strengthen teacher professionalism based on Islamic values through an integrative approach. The research used a qualitative method with a case study design conducted through field study activities, with the researcher acting as a teaching assistant in the Educational Science and Profession course at the Mathematics Education Study Program, Faculty of Tarbiyah and Teacher Training, Universitas Islam Negeri Sunan Kalijaga Yogyakarta. Data collection was conducted over one semester through participatory observation of the lecture process, semi-structured interviews with lecturers and students, and analysis of learning documents, including the Semester Learning Plan, teaching modules, presentation materials, student papers, and course learning achievement instruments. The data were analyzed using thematic analysis to identify patterns of value integration, learning dynamics, and the construction of teacher professionalism. The results of the study show that the integration of Islamic values such as trustworthiness, honesty (ṣidq), intelligence (faṭānah), compassion (raḥmah), and good character (akhlak karimah) serve as an epistemological and ethical framework that enriches students' understanding of educational science and the teaching profession. This integrative approach has been proven to increase student activity, encourage critical reflection, and shape a holistic paradigm of teacher professionalism through the integration of cognitive, affective, and moral-spiritual dimensions. This research has implications for the urgency of reconstructing the education curriculum, which systematically integrates Islamic values at the epistemological, pedagogical, and axiological levels in order to build teacher professionalism that is characterful, has integrity, and is relevant to the educational needs of the present and the future.
