Abstract

Feeding fish in pond-based aquaculture involves the hand distribution of food by individuals around the pond's perimeter. Farmers utilize boats to achieve extensive food delivery. Technological advancements have facilitated the creation of self-feeder or dement-feeder statistical techniques. This device functions autonomously to provide feed at regular intervals and has a predetermined coverage area at its designated position on the periphery of ponds. Due to its peripheral location, the technology deployment system has limited capacity to distribute feed across the entire pond area, making it less effective for use in big ponds. Hence, it is imperative to develop a solar-powered unmanned boat (Petates) equipped with an Auto Feeder system to regulate the feeding process in shrimp and fish farming. This study aims to develop a solar-powered unmanned boat design for fish and shrimp farming that can efficiently distribute feed across the pond. Additionally, the research aims to assess the impact of feeding machines on the conversion of feed by fish and shrimp. The research results show that the maximum floating weight of the boat is 48.7 kg using two solar-powered electromotor-driven buoys. The boat has a maximum speed acceleration of 2.4 m/s, achieved through a well-balanced and efficient bow acceleration. Experiments were conducted using two distinct feed types: type 781-2 with a diameter ranging from 2.3 to 3 mm, and type 781-3 with a diameter ranging from 3.2 to 4 mm. The throwing distance for the feed is between 8 and 10 meters, and between 7 and 8 meters. The feed spreading rate for each minute is 950 grams and 1,080 grams, with a feed capacity of 7 kilograms and 6 kilograms respectively.

Abstract

Analisis dilakukan terhadap tiga kelompok ikan pada ekosistem yang berbeda. Ikan gabus yang digunakan bobot rata-rata 190 gram. Pengambilan sampel plankton mengunakan planktonet yang kemudian diawetkan menggunakan alkohol. Sedangkan daging ikan dilakukan pengujian kadar albumin dan komposisi proksimat. Penelitian bertujuan mengamati pengaruh ekosistem yang berbeda terhadap kadar albumin ikan gabus. Metode yang digunakan yaitu metode deskriptif untuk menggambarkan kadar albumin, komposisi proksimat ikan gabus dari berbagai ekosistem perairan. Sedangkan data kualitas air yang diamati meliputi suhu, pH, DO, Amonia. Berdasarkan hasil penelitian menunjukkan kadar albumin tertinggi terdapat pada ikan gabus di danau yaitu sebesar 5,75%, diikuti oleh ikan pada ekosistem rawa yaitu 2,64%, dan terendah pada ikan gabus di ekosistem sungai yaitu sebesar 1,27%. Hasil analisis proximat daging menunjukkan kadar protein tertinggi terdapat pada ikan gabus di ekosistem danau sebesar 17,16%,  diikuti oleh rawa sebesar 16,88%, dan sungai sebesar 16,41%. Parameter kualitas air menunjukkan suhu pada kisaran 25-33oC, pH kisaran 5-6,7. Oksigen terlarut berkisar 2-7 ppm, dan kadar ammonia 0,25-0,33 ppm. hasil identifikasi plankton yang menunjukkan bahwa kelimpahan species plankton paling banyak ditemukan pada ekosistem danau dengan species Chlorella yang ditemukan pada ketiga ekosistem perairan tersebut.

Abstract

Palm kernel meal is considered very potential to be used as fish feed because it contains 15.43% crude protein. The problem by aquaculture is the imbalance in income obtained compared to production costs that have been incurred. This is because farmers depend on manufactured feed so that the price of commercial feed issued is high. The purpose of this study was to analyze the effect of different soybean meal and palm kernel meal feed substitutions on the growth and survival of catfish (Clarias sp). The study used a Completely Randomized Design with 3 treatments and 4 repetitions, consisted of three main treatments, namely: the first treatment (P1) feed based on a ratio of 80% soybean meal with 20% palm kernel meal and the second treatment (P2) feed based on 70% soybean meal and 30% palm kernel meal and (P3) feed based on 60% soybean meal and 40% palm kernel meal...The highest Weight gain value was found in P1 at 71.3 gr, followed by P2 at 51.5 gr, and P3 at 47.6 gr. The results showed that the highest RGR value was found in treatment P1 at 0.3% followed by treatments P2 and P3 at 0.2%. The best Feed Covertion Ratio (FCR) was found in treatment P1 at 4.31, followed by treatment P2 at 5.85 and treatment P3 at 6.22. The highest SR in treatment was found in treatment P1 at 91.7% followed by P2 and P3 at 90%.
