Pemilik lahan sendiri lebih bebas melakukan apa yang akan lakukannya sementara penyewa dan gadai dibatasi oleh beberapa peraturan yang telah disepakati. Hal tersebut dapat menyebabakan perbedaan pengelolaan dari ketiga status kepemilikan lahan yang ada. Untuk menganalisis kemungkinan perbedaan pengelolaan tersebut, penelitian ini dilakukan di Desa Sukamandi Hilir Kecamatan Pagar Merbau Kabupaten Deli Serdang. Metode yang digunakan dalam penelitian ini adalah metode analisis diskriptif dan ANOVA. Untuk melihat perbedaan biaya produksi dan produktivitas maka diambil 30 petani sampel. Hasil penelitian menunjukkan bahwa biaya produksi lahan milik sendiri paling tinggi dibandingkan lahan sewa dan lahan gadai. Sebaliknya produktivitas lahan milik sendiri lebih rendah dibandingkan keduanya, hasil uji ANOVA menunjukkan bahwa perbedaan biaya produksi dan produktivitas cukup signifikan. Kata Kunci : Status Lahan, Pengelolaan, Biaya Produksi, Produktivitas.

Enzymes play a vital role in improving nutrient absorption and digestion efficiency in fish feed, particularly for indigenous Indonesian fish species. This review aimed to comprehensively evaluate the current state of enzyme utilization in feed for native Indonesian fish, highlighting its benefits, challenges, and potential contributions to the advancement of sustainable aquaculture. It examined the role of endogenous enzymes and various exogenous enzymes, such as protease, lipase, phytase, Non-Starch Polysaccharides (NSP) enzymes, and multi-carbohydrase complexes, in enhancing feed efficiency and fish growth. The integration of these enzymes into feed formulations offers significant advantages in boosting growth performance, optimizing feed conversion efficiency, and promoting environmental sustainability. Additionally, this review discussed the potential benefits and challenges associated with enzyme application in fish feed. Looking ahead, the development of enzyme utilization in aquafeed holds great promise for enhancing the sustainability, efficiency, and productivity of the aquaculture sector. This review provides valuable insights into the potential of enzyme supplementation to maximize feed utilization for native Indonesian fish species, outlining both its advantages and challenges, while also exploring its future prospects in driving cost-effective and eco-friendly aquaculture practices.

This study aimed to formulate planning and development strategies for the tourism industry in Panai Hilir District, Labuhanbatu Regency, North Sumatra, using SWOT and QSPM methods. The region holds significant natural and cultural tourism potential, but it has not been optimally developed due to limitations in infrastructure, promotion, and community involvement. This research employed a descriptive approach through the collection of primary and secondary data, which were then analyzed using IFAS, EFAS, SWOT, and QSPM matrices. The SWOT analysis resulted indicate strengths such as natural and cultural richness and community support, and weaknesses including limited facilities and infrastructure. Opportunities included government policies and community support, while threats involve competition from other regions and economic-political conditions. The QSPM analysis produced four main strategies, with the highest priority being the improvement of living standards and community welfare through the tourism sector, followed by infrastructure development, management system enhancement, and capacity building of human resources. These findings are expected to serve as a strategic policy foundation for sustainable tourism development in Panai Hilir and contribute to local economic growth and cultural preservation.
