Abstract

Proses pemijahan ikan mas (Cyprinus carpio) dapat dilakukan secara alami atau tradisional. Akan tetapi fekunditas dan fertillisasi dari pemijahan tersebut masih cukup rendah. Untuk itu perlu dilakukan pemijahan secara buatan melalui aplikasi hormonal dengan menggunakan teknik hipofisasi untuk merangsang dan mempercepat ovulasi serta pemijahan induk ikan dan mampu meningkatkan fekunditas, hatching rate,dan kuantitas benih ikan. Kelenjar hipofisa katak sawah (Fejervarya cancrivora) memiliki beberapa kelenjar endokrin yang bertugas menghasilkan hormon untuk mengatur dan mengontrol tugas-tugas tubuh, merangsang, dan mengaktifkan jaringan reproduksi. Penelitian ini bertujuan untuk menguji dosis penggunaan kelenjar hipofisa katak sawah yang paling efektif untuk meningkatkan fekunditas dan hatching rate ikan mas. Metode yang digunakan yaitu metode eksperimen terdiri dari empat perlakuan dosis kelenjar hipofisa katak sawah, yaitu P1 (0 mL kg-1), P2 (0,3 mL kg-1), P3 (0,5 mL kg-1), dan P4 (0,7 mL kg-1) dengan tiga ulangan. Data yang diperoleh dianalisis secara statistik dengan menggunakan analysis of variance (ANOVA). Hasil penelitian menunjukkan bahwa dosis yang paling efektif untuk meningkatkan fekunditas danhatching rate ikan mas adalah 0,5 mL kg-1. Fekunditas tertinggi sebesar 85.516,51 ± 2.110,94 butir dengan hatching ratesebesar 76,87 ± 1,33%.Penggunaan dosis yang rendah mengakibatkan hormon tidak mencapai konsentrasi yang cukup untuk merangsang respons reproduksi yang diinginkan. Sebaliknya, dosis yang terlalu tinggi dapat menyebabkan terjadinya overstimulasi sistem reproduksi ikan, yang pada akhirnya dapat mengganggu keseimbangan hormonal akibat toksisitas.The spawning process of carp (Cyprinus carpio) can be done naturally or artificially. However, fecundity and fertilization from spawning are still quite low. For this reason, it is necessary to carry out artificial spawning through hormonal applications using pituitary techniques to stimulate and accelerate ovulation and spawning of parent fish and is able to increase fecundity, hatching rate and quantity of fish fry. The pituitary gland of crab-eating frog (Fejervarya cancrivora) has several endocrine glands whose job is to produce hormones to regulate and control body tasks, stimulate, and activate reproductive tissue. This study aimed to test the most effective dose of crab-eating frog's pituitary gland to increase the fecundity and hatching rate of carp. The method used was the experimental method consisting of four treatments of crab-eating frog’s pituitary gland doses, namely P1 (0 mL kg-1), P2 (0.3 mL kg-1), P3 (0.5 mL kg-1), and P4 (0.7 mL kg-1) with three replications. The data obtained were analyzed statistically using analysis of variance (ANOVA). The results showed that the most effective dose for increasing fecundity and hatching rate of carp was 0.5 mL kg-1. The highest fecundity was 85,516.51 ± 2,110.94 eggs with a hatching rate of 76.87 ± 1.33%. The use of low doses resulted in the hormone not reaching sufficient concentrations to stimulate the desired reproductive response. On the other hand, doses that are too high can cause overstimulation of the fish's reproductive system, which in turn can disrupt the hormonal balance due to toxicity.

Abstract

The Covid-19 pandemic has caused an economic crisis, the price of feed is increasing so that the selling price of catfish no longer matches the price of the feed provided. The focus of community service in the Tanjung Kasau Plantation village is to assist fish farmers in managing and increasing fish farmers' income. The priority objective of this activity is efforts to improve the economy, namely increasing income in terms of production costs, both fish feed, production cost management and training in maggot cultivation by utilizing surrounding waste, namely solid palm oil waste. The implementation method is carried out in 3 stages which involve problems in the fields of production and management. This service activity uses education, training and mentoring methods. Community-Based Empowerment Activities carried out at the Tangkas Mina Jaya Group in Tanjung Kasau Plantation Village ran smoothly, marked by good community participation from the start to the end of the activity. Community-Based Empowerment Activities also provide a positive impact by increasing community knowledge and skills

Abstract

Penelitian ini bertujuan untuk mengetahui tingkat kelayakan Pantai Salbe Nauli Beach di Desa Togu Domu Nauli, Kecamatan Dolok Pardamean, Kabupaten Simalungun sebagai destinasi ekowisata. Metode penelitian yang digunakan adalah deskriptif kuantitatif dengan pendekatan studi kasus lapangan. Data dikumpulkan melalui observasi, wawancara, dokumentasi, dan penyebaran kuesioner kepada wisatawan dan masyarakat sekitar. Analisis data dilakukan menggunakan metode statistik deskriptif berdasarkan empat aspek utama pariwisata, yaitu daya tarik, aksesibilitas, amenitas, dan dukungan masyarakat. Hasil penelitian menunjukkan bahwa Pantai Salbe memiliki nilai rata-rata kelayakan sebesar 3,768, yang termasuk dalam kategori “layak” untuk dikembangkan sebagai destinasi ekowisata. Hasil analisis SWOT menunjukkan bahwa kekuatan utama Pantai Salbe terletak pada daya tarik alam yang indah dan dukungan masyarakat lokal, sementara kelemahannya adalah keterbatasan fasilitas dan pengelolaan. Peluang pengembangan terbuka melalui dukungan pemerintah dan tren wisata berbasis alam, sedangkan ancaman yang dihadapi antara lain potensi degradasi lingkungan dan persaingan dengan destinasi lain di kawasan Danau Toba. Dengan demikian, pengembangan Pantai Salbe sebaiknya difokuskan pada peningkatan fasilitas, perbaikan aksesibilitas, serta penguatan partisipasi masyarakat dalam pengelolaan wisata secara berkelanjutan.

Abstract

Puput Fish (Ilisha Elongata) is an economic fish that is continuously utilized by fisheries actors to meet the demand for public consumption. Research on the Relationship between the Length and Weight of Puput Fish (Ilisha Elongata) Landed at Tanjung Tiram Batu Bara Port was conducted on August 5-September 4, 2025. This study aims to measure the length and weight of Puput Fish (Ilisha Elongata), To determine the body shape of Puput Fish (Ilisha Elongata), To determine the condition of the waters where Puput Fish (Ilisha Elongata) are caught, and the results of this study may be a reference in maintaining Puput Fish (Ilisha Elongata) resources for fishermen who catch Puput Fish (Ilisha Elongata) excessively using survey and analysis methods. The results of this study were obtained from a total of 50 fish, namely fish lengths ranging from 141 mm to 189 mm, where the dominant total length of fish caught was in the average range of 162.08 mm. Meanwhile, the weight of Puput Fish (Ilisha Elongata) ranges from 24 to 52 grams, with an average fish weight of 38.10 grams. The result of the b value calculation obtained in the Puput Fish (Ilisha Elongata) test is 1.3537. Based on the b value obtained, it can be stated that the length of the fish weight is <3, which means negative allometric which means that the length growth is faster than the weight growth. The result of the K calculation in the Puput Fish (Ilisha Elongata) test is 2.7609 which means that the shape of the fish is flat (plump).
