Abstract

This study examines input and output analysis as a form of matrix application that functions as a mathematical model to understand the interrelationships between activities in an economy. Learning and mastery of mathematics are crucial because many problems require the ability to formulate concepts mathematically through modeling. This study uses the Matrix Inverse Method and the Gauss-Jordan Elimination Method. The calculation process is performed using MATLAB (Matrix Laboratory) software, which facilitates efficient handling of mathematical operations.

Abstract

Konservasi sumber daya alam (SDA) kerap dipahami semata sebagai persoalan ekologis, padahal di dalamnya melekat dimensi ekonomi yang mendasar, yaitu kelangkaan, pilihan, dan biaya peluang. Penelitian ini bertujuan menganalisis konsep konservasi SDA dari sudut pandang ekonomi sumber daya alam, mencakup keterkaitan antara prinsip konservasi, kelangkaan dan efisiensi pemanfaatan, nilai ekonomi total, eksternalitas, serta strategi pengelolaan SDA yang berkelanjutan. Riset memakai pendekatan kualitatif dengan metode studi literatur (library research) atas sejumlah buku dan artikel jurnal mengenai konservasi dan ekonomi sumber daya alam, yang dianalisis secara tematik. Hasil kajian menjelaskan dimana konservasi tidak dapat dilepaskan dari logika ekonomi karena menyangkut alokasi sumber energi yang langka di antara pemanfaatan generasi saat ini serta generasi mendatang. Nilai ekonomi total (Total Economic Value), yang mencakup nilai guna langsung, nilai guna tidak langsung, nilai opsi, serta nilai keberadaan, memperlihatkan bahwa manfaat SDA jauh lebih luas daripada yang tergambar pada harga pasar, sehingga eksploitasi berlebihan yang mengabaikan eksternalitas cenderung menimbulkan kegagalan pasar. Konservasi, dengan begitu, dapat dipahami sebagai strategi ekonomi untuk menjaga aliran manfaat SDA secara berkelanjutan, yang membutuhkan sinergi antara kebijakan pemerintah, mekanisme pasar yang mencerminkan biaya lingkungan, dan partisipasi masyarakat dalam pengelolaannya.

Abstract

Indonesia’s halal certification regime involves consumer protection, freedom of religion, standardization, and international trade. Within the World Trade Organization (WTO) framework, mandatory halal certification may be examined as a technical regulation and/or conformity assessment procedure related to the Agreement on Technical Barriers to Trade (TBT). The issue has become more relevant following the signing of the Agreement on Reciprocal Trade (ART) between Indonesia and the United States on 19 February 2026. This study analyzes the legal position of halal certification under WTO law, the implications of the ART for the recognition of foreign halal certification, and the potential consequences for domestic industries and micro, small, and medium enterprises (MSMEs). This normative legal research applies statutory, conceptual, and international-agreement approaches. Primary legal materials include Law Number 33 of 2014 on Halal Product Assurance and its amendments, the TBT Agreement, GATT 1994, the ART documents, and official government explanations. The study finds that the ART does not abolish halal certification requirements for food and beverages; rather, it addresses non-tariff barriers, standards, conformity assessment procedures, and recognition of foreign halal bodies. Such recognition must be transparent, objective, verifiable, and consistent with Indonesia’s legitimate level of consumer protection. The principal risk for domestic industries is not simply increased imports, but an imbalance in compliance costs and procedures. The government should therefore equalize procedural treatment, accelerate MSME certification, strengthen post-market surveillance, and ensure that technical measures are applied in a non-discriminatory manner.
