Abstract

Penelitian ini bertujuan untuk menentukan penguasaan hasil belajar matematika di kalangan siswa kelas X di SMAN 1 Peukan Bada melalui penerapan model pembelajaran Probing-Prompting. Populasi penelitian terdiri dari seluruh siswa kelas X di SMAN 1 Peukan Bada, dengan sampel dipilih menggunakan purposive sampling. Sampel terdiri dari 20 siswa dari kelas X-2. Data dikumpulkan melalui tes akhir yang terdiri dari tiga pertanyaan esai yang diberikan setelah perlakuan. Hasil menunjukkan rata-rata sampel sebesar 86,15, melebihi kriteria penguasaan minimum (KKM) sebesar 70. Pengujian hipotesis menggunakan uji-t dengan tingkat signifikansi α=0,05 dan 19 derajat kebebasan (df) menghasilkan tobserved > ttable (7,78 > 1,729). Akibatnya, H0 ditolak dan Ha diterima. Dapat disimpulkan bahwa hasil belajar siswa menggunakan model Probing-Prompting berhasil mencapai penguasaan. This study aims to determine the mastery of mathematics learning outcomes among Grade X students at SMAN 1 Peukan Bada through the implementation of the Probing-Prompting learning model. The research population consisted of all Grade X students at SMAN 1 Peukan Bada, with the sample selected using purposive sampling. The sample included 20 students from class X-2. Data were collected through a post-test consisting of three essay questions administered after the treatment. The results showed a sample mean of 86.15, exceeding the minimum mastery criterion (KKM) of 70. Hypothesis testing using a t-test with a significance level of α=0,05 and 19 degrees of freedom (df) resulted in tobserved > ttable (7,78 > 1,729). Consequently, H0 was rejected and Ha was accepted. It can be concluded that student learning outcomes using the Probing-Prompting model successfully achieved mastery.

Abstract

Women’s economic empowerment through micro, small, and medium enterprises (MSMEs) is widely recognized as an important strategy for supporting household livelihoods and local economic resilience. However, women entrepreneurs continue to face structural and socio-cultural constraints, particularly in rural contexts. This study aims to explore how women-owned MSMEs are experienced in relation to family welfare and how empowerment is shaped by Islamic values and local wisdom in Aceh Besar Regency. This study employed a qualitative field research approach. Data were collected through semi-structured interviews, observations, and documentation involving 12 women MSME actors selected using purposive sampling. Participants were aged 20–45 years, engaged in culinary, handicraft, and small-scale retail businesses, with business experience ranging from 1 to 10 years. Each interview lasted approximately 45–60 minutes. Data were analyzed using the interactive model of Miles, Huberman, and Saldana. The findings suggest that participants reported contributing to household income, particularly in meeting daily needs and supporting children’s education. MSME activities were also described as helping households manage financial uncertainty. Participants indicated that Islamic values, such as honesty, fairness, and avoidance of riba, along with local practices such as community cooperation, influenced business practices and supported customer trust. At the same time, participants reported ongoing challenges, including limited access to capital, markets, and technology. These findings suggest that women’s involvement in MSMEs is perceived as meaningful for household welfare, while also being shaped by broader structural and socio-cultural contexts.

Abstract

This study examines the integration of production system optimization, supply chain management, and market risk management in the plastic recycling industry within a circular economy context. Using a qualitative systematic literature review approach covering publications from 2017 to 2025, this study synthesizes findings from Scopus, Web of Science, OECD, and World Bank sources. The results indicate that production optimization strategies such as lean manufacturing, process simplification, energy efficiency, and capacity planning enhance cost efficiency and operational stability. At the same time, effective supply chain management, including reverse logistics coordination, supplier diversification, and inventory control, strengthens supply chain resilience and reduces disruption risks. Cost efficiency and supply stability increase price flexibility, which mitigates market risk exposure and supports profitability stability. The study proposes an integrative conceptual framework linking production optimization, supply chain coordination, market risk mitigation, and profitability resilience. The findings contribute to bridging operations management and risk governance literature while offering practical insights for improving competitiveness and sustainability in the plastic recycling sector.

Abstract

Penelitian ini bertujuan untuk menganalisis kebijakan perizinan yang diterapkan oleh Dinas Kesehatan Kota Subulussalam dalam rangka meningkatkan pelayanan publik di sektor kesehatan. Fokus utama dari kajian ini adalah bagaimana implementasi kebijakan perizinan, efektivitas proses perizinan, serta tantangan yang dihadapi dalam pelaksanaannya. Dengan menggunakan pendekatan kualitatif deskriptif, data diperoleh melalui wawancara dengan pegawai Dinas Kesehatan, pengamatan langsung, serta telaah dokumen kebijakan. Hasil penelitian menunjukkan bahwa meskipun Dinas Kesehatan telah menerapkan sistem perizinan yang sesuai dengan regulasi nasional, namun masih terdapat beberapa kendala, seperti keterbatasan sumber daya manusia, kurangnya pemahaman masyarakat terhadap prosedur perizinan, serta lambatnya integrasi sistem digitalisasi. Oleh karena itu, diperlukan upaya perbaikan dalam bentuk peningkatan kapasitas aparatur, sosialisasi kebijakan, dan modernisasi sistem perizinan untuk mewujudkan pelayanan kesehatan yang transparan, cepat, dan akuntabel.

Abstract

Penerapan ekonomi sirkular pada industri daur ulang plastik semakin mendapat perhatian sebagai strategi untuk mengurangi limbah, meningkatkan efisiensi sumber daya, dan mendukung pembangunan berkelanjutan. Penelitian ini bertujuan menganalisis konsep ekonomi sirkular, mengidentifikasi tren penerapan, mengevaluasi tantangan implementasi, serta mengkaji prospek penelitian pada industri daur ulang plastik. Penelitian menggunakan pendekatan kualitatif deskriptif dengan metode narrative literature review melalui sintesis literatur dari berbagai publikasi ilmiah bereputasi internasional yang diperoleh dari Scopus, ScienceDirect, SpringerLink, Wiley Online Library, Google Scholar, dan Taylor & Francis Online. Analisis dilakukan secara naratif dan tematik berdasarkan lima kelompok pembahasan utama. Hasil kajian menunjukkan bahwa perkembangan ekonomi sirkular didorong oleh inovasi teknologi, digitalisasi, penerapan Extended Producer Responsibility (EPR), serta model bisnis berbasis closed loop supply chain. Meskipun demikian, implementasinya masih menghadapi kendala teknis, ekonomi, sosial, dan kelembagaan. Penelitian ini memberikan sintesis komprehensif mengenai perkembangan ekonomi sirkular pada industri daur ulang plastik sekaligus mengidentifikasi peluang penelitian masa depan yang mendukung transformasi menuju industri yang lebih berkelanjutan.
