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.

The agriculture development of progressive crop land consists of three significant factors such as human resources, natural resources and appropriate technology. The method used in the research is survey, a kind of research of which data is collected from samples over population to represent all population. The type of survey used is explanatory research, a kind of research means to explain the position of variables researched and the relation between a variable and another. The population of the research was all the youths in Labuhan batu Utara being 17-30 years old. According to BPS data in 2013, there were 46,091 youths in Labuhan batu Utara. Sampling used simple sampling random method where sample taken randomly from population based on the probability frequency of all the population’s members. By using the formula of Frank Lynk, it was obtained 96 sample respondents. The conclusion of the research is 1) the youths’ perception to the agriculture development of progressive crop land in Labuhanbatu Utara is positive, 2) the youths’ role to the agriculture development of progressive crop land in Labuhanbatu Utara is positive and 3) the effect of the youths’ role as the agent of change, the agent of development and the agent of modernization is simultaneously significant to the agriculture development of progressive crop land in all the aspects- human resources, natural resources and appropriate technology. Meanwhile the variable of the agent of modernization effects positively but is not significant to the agriculture development of progressive crop land.

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.
