Abstract

This research examines the productive zakat development model in Indonesia and Brunei Darussalam through a comparative approach. Productive zakat is an effort to utilize zakat funds to improve the economic welfare of mustahik in a sustainable manner. In Indonesia, zakat is regulated by Law no. 23 of 2011 and managed by the National Amil Zakat Agency (BAZNAS) and various Amil Zakat Institutions (LAZ). Meanwhile, in Brunei Darussalam, zakat is managed by the Brunei Islamic Religious Council (MUIB) based on sharia law. This study found that the two countries have different approaches but both focus on empowering the mustahik economy through programs such as providing business capital, skills training and assistance with production equipment. Indonesia shows diversity in program implementation with extensive collaboration between various institutions, while Brunei Darussalam utilizes full government support for more focused and effective program implementation. Challenges facing Indonesia include unequal distribution and weak supervision, while Brunei faces challenges in economic diversification. However, both countries have great opportunities to increase the effectiveness of productive zakat programs through technological innovation and closer collaboration between the public and private sectors. This study provides insight into best practices and lessons that can be drawn from each country to improve the welfare of mustahik in a sustainable manner. The conclusion of this research emphasizes the importance of strengthening the legal and institutional framework, as well as increasing transparency and accountability in the management of productive zakat.

Abstract

Pesut mahakam (Orcaella brevirostris) merupakan mamalia akuatik endemik yang hidup di Kawasan Konservasi Perairan Mahakam Wilayah Hulu. Statusnya sudah dikategorikan critically endangered oleh IUCN dan tergolong pada Appendiks I CITES. Penurunan populasinya yang terjadi setiap tahun menjadikan upaya konservasi penting untuk segera dilakukan. Upaya konservasi yang dilakukan oleh pemerintah adalah dengan menetapkan Kawasan Konservasi di Perairan Mahakam Wilayah Hulu Kabupaten Kutai Kartanegara melalui Keputusan Menteri Kelautan dan Perikanan Nomor 49 Tahun 2022. Penetapan kawasan konservasi ini didukung dengan Keputusan Direktur Jenderal Pengelolaan Kelautan dan Ruang Laut Nomor 61 Tahun 2023 tentang Rencana Pengelolaan Kawasan Konservasi di Perairan Mahakam Wilayah Hulu Kabupaten Kutai Kartanegara 2023-2042. Penelitian ini bertujuan untuk memberikan rekomendasi terhadap rencana pengelolaan kawasan konservasi yang telah dilakukan. Metode yang digunakan dalam penelitian ini adalah metode deskriptif. Data primer yang diambil terdiri atas data pemahaman masyarakat, data kondisi sosial ekonomi masyarakat, serta data pemantauan penggunaan alat tangkap tidak ramah lingkungan. Hasil penelitian menunjukkan bahwa terdapat peningkatan pemahaman masyarakat terhadap kawasan konservasi setelah dilakukan sosialisasi. Namun, terdapat beberapa tantangan dan pelanggaran, seperti penggunaan alat tangkap tidak ramah lingkungan dan tingkat pendidikan masyarakat. Beberapa rekomendasi yang dapat diberikan terhadap rencana pengelolaan kawasan konservasi adalah: (1) peningkatan keterlibatan masyarakat melalui program pemberdayaan masyarakat, pendidikan penggunaan alat tangkap ramah lingkungan, dan pengembangan ekonomi alternatif yang berkelanjutan; (2) peningkatan pendidikan konservasi secara formal maupun informal; (3) pengenalan inovasi alat tangkap ikan dengan pemasangan perangkat akustik yang dapat mengusir pesut; dan (4) penguatan penegakan hukum dengan pelibatan champion atau warga desa yang tergabung dalam pokmaswas.

Abstract

The abstract and symbolic nature of chemistry presents significant learning challenges for students, particularly in the understanding of foundational concepts through a variety of representations. It's tougher to teach well, especially in Indonesia, because there are not many trustworthy instruments to measure students' interpretative skills, which are very important for representational competence. The goal of this study was to fill this gap by creating and testing a reliable assessment tool called the Assessment of Representational Competence in Fundamental Chemical Laws (ARC-FCL), which was meant to measure the interpretative skills of Indonesian senior high school students.  The Define, Design, and Develop stages of the 4D model were employed in the Research and Development process of this study design. The Kozma-Russell framework and the Three-Dimensional Learning Assessment Protocol (3D-LAP) helped shape the instrument's development. The ARC-FCL test has two levels of multiple-choice and essay questions about the laws of Lavoisier, Dalton, and Gay-Lussac. Two chemistry education professors and one experienced instructor reviewed the content to ensure its validity. Researchers got real-world data for psychometric analysis from 30 11th-grade students at a senior high school in Lampung, Indonesia. The study looked at item validity using Pearson correlation, item discrimination, and internal consistency reliability using Cronbach alpha. All three designed items had great validity, with correlation values over the key threshold of 0.361 and good discrimination indices between 0.50 and 0.75. The instrument was somewhat reliable, with a Cronbach alpha coefficient of 0.572. This is fine for a formative diagnostic tool at this early stage of development. Item analysis also showed that students had the most trouble with the question about the Law of Multiple Proportions.  In conclusion, this study developed a valuable and valid instrument for identifying the specific challenges faced by students when attempting to comprehend sub-microscopic representations of fundamental chemical principles. As a formative assessment instrument that fits with the Kurikulum Merdeka, the ARC-FCL is quite useful for Indonesian teachers. It encourages a move from memorizing things by heart to comprehending them better and learning how to do science. Future work should be focused on adding more items to the bank to make it more reliable and cover more ground. Keywords: representational competence, assessment instrument, interpretive skills, basic chemical laws, 4D model, instrument validation.
