Abstract

Produksi abalon (Haliotis squamata) saat ini lebih banyak diperoleh dari tangkapan di alam, sehingga dikhawatirkan terjadinya pengambilan yang tak terkendali. Ketersediaan pakan sangat penting bagi kelangsungan hidup abalon. Penelitian ini bertujuan untuk mengetahui jenis pakan yang terbaik terhadap kematangan gonad abalon. Penelitian dilakukan di Balai Budidaya Laut Lombok (BBL) Kecamatan Sekotong Barat, Kabupaten Lombok Barat, pada bulan Juni-Agustus 2012. Metode yang digunakan adalah metode eksperimental dengan rancangan acak lengkap (RAL) terdiri dari 3 perlakuan jenis pakan yaitu Gracillaria sp, pellet, dan agar, masing-masing perlakuan diulang sebanyak 6 kali. Hasil penelitian menunjukkan bahwa jenis pakan yang berbeda mempengaruhi perkembangan gonad. Pakan Gracillaria sp memberikan tingkat kematangan gonad yang lebih baik dibandingkan dengan pakan agar dan pellet. Masa waktu minimum untuk abalon mengalami perkembangan gonad adalah 43 hari. Waktu yang diperlukan untuk mengalami perkembangan gonad dari TKG 0 ke TKG 1 adalah ±21 hari, dari TKG 1 ke TKG 2 adalah ±14 hari, dan dari TKG 2 ke TKG 3 adalah ±14 hari. Kualitas air selama proses pematangan gonad adalah: suhu 26,0-26,2oC, pH 6,5-6,6, salinitas 34,1-34,6 ppt, DO 3,9-4,4 mg/l. Nilai kualitas air tersebut, masih dalam kisaran optimum kehidupan abalon.

Abstract

This research aims to comprehensively examine the alignment between Muhammadiyah's Manhaj Tarjih logic and mathematical thinking, alongside its implications for education, humanization, and enlightenment dawah. Employing a qualitative approach through library research, data were gathered from primary sources, including official organizational documents, educational philosophy literature, and relevant national and international scientific journals. The analysis was conducted using inductive and reflective content and thematic analysis to achieve a holistic understanding. The findings reveal a robust epistemological alignment between Manhaj Tarjih logic and mathematical reasoning, particularly regarding rationality, systematic structure, and consistency. Furthermore, mathematics education serves a strategic role in integrating Muhammadiyah’s scientific mission, fostering humanistic awareness, and internalizing Islamic values into pedagogical practices. This study concludes that mathematics is an essential medium for developing progressive Islamic education that is critical, rational, and welfare-oriented. Ultimately, this synergy strengthens the enlightenment dawah movement, ensuring it remains adaptive to modern scientific dynamics while staying firmly rooted in humanistic principles and religious values.

Abstract

This study aims to map and analyze global trends in the use of Linear Regression in Education Systems quantitatively, including publication counts, citations, author collaboration patterns, institutional affiliations, and country contributions. Publication data from the Dimensions database covering 2010–2025 were analyzed using bibliometric methods with VOSviewer, while literature selection followed the PRISMA framework to ensure validity and transparency. The results revealed 2,987 publications with a total of 12,647 citations, showing a significant increase since 2017, particularly in the fields of Education Systems, Education, and Curriculum and Pedagogy. Network, overlay, and density visualizations confirmed Linear Regression as a central method in Educational research, closely related to teacher performance, student learning outcomes, and engagement. Although researcher collaboration remains fragmented, the dominance of quantitative and computational journals demonstrates the wide and interdisciplinary application of Linear Regression, including integration with digital learning and financial literacy. These findings highlight the relevance of Linear Regression in evidence-based Educational research and suggest opportunities for advancing analytical methods and international collaboration in the future.
