Abstract

This study was conducted to explore the culture technique of Chaetoceros calcitrans as a natural feed and its role in supporting the maintenance of the brown mussel (Mytilopsis adamsi). The microalga was chosen because it provides essential nutrients such as proteins, lipids, and carbohydrates that are important for the growth of aquatic organisms. The work took place over one month, from May 6 to June 4, 2025, at the National Research and Innovation Agency (BRIN), North Lombok. The culture followed a stepwise approach, starting with sterilization of equipment and media, the addition of KW21 fertilizer and silicate, inoculation with five-day-old seed cultures, daily maintenance, and cell density monitoring. The observations showed that C. calcitrans density rose steadily from the first day and peaked on day 5 at 4,020,000 cells/ml, before declining by day 7. This trend reflects the typical growth phases of microalgae, from lag and exponential to stationary and death phases. Feeding trials involved offering C. calcitrans to brown mussels twice daily at a dose of 500 ml each time. The results indicated consistent weight gain across all replicates, although growth levels varied among treatments. Overall, the study confirms that stepwise culture with appropriate nutrient supply and water quality management can produce C. calcitrans at optimal densities. Its application as a natural feed also provides measurable benefits for the growth of brown mussels in culture systems.

Abstract

Lobster pasir (Panulirus homarus) salah satu komoditas perikanan dengan nilai ekonomi tinggi yang memiliki permintaan besar di pasar lokal maupun internasional. Peningkatan kebutuhan tersebut menjadikan budidaya lobster pasir sebagai peluang usaha yang potensial dan menguntungkan bagi masyarakat pesisir di Dusun Ujung Betok. Dusun Ujung Betok merupakan wilayah pesisir yang memiliki potensi sumber daya laut dan wilayah yang ditetapkan sebagai kawasan budidaya lobster pasir di NTB. Masyarakat nelayannya memiliki sebuah Kelompok Usaha Bersama (KUB) yang bernama Segare Lauq yang bergerak dibidang perikanan dan hasil budidaya laut terutama lobster. Kendala utama yang dihadapi oleh pembudidaya adalah kondisi benih tidak 100% sehat dan siap dibudidayakan. Hampir 50% benih yang didatangkan dari luar atau ditangkap dari alam, dalam satu hingga dua hari pemeliharaan akan mengalami kematian. Permasalahan tersebut dapat diatasi dengan cara penanganan (karantina) benih di dalam sebuah wadah yang disebut wadah karantina sebelum ditebar. Tim pengabdian melakukan sosialisasi dan pendampingan teknis dalam pembuatan wadah karantina dan pemanfaatannya. Wadah karantina didisain berbentuk tabung dengan ketinggian 1,5 m, diameter 1 m dan ukuran mata jaring 1 inch. Melalui penyediaan wadah karantina diharapkan mampu mendukung kegiatan budidaya lobster untuk menghasilkan benih yang lebih sehat, seragam dan siap dibudidayakan. Selain itu wadah karantina berfungsi untuk menampung lobster yang baru dipanen, sehingga dapat memudahkan pembudidaya dalam sortasi dan  mengurangi stress pada lobster yang siap kirim. Kegiatan program pengabdian melalui skema Pengabdian Karya Dosen yang Dimanfaatkan Masyarakat ini juga diharapkan bisa meningkatkan kinerja yaitu pada IKU 5, hasil kerja dosen dapat digunakan dan dimanfaatkan oleh masyarakat.

Abstract

Kegiatan pengabdian masyarakat ini berfokus pada penerapan teknologi aerasi microbubble venturi untuk mengatasi permasalahan utama budidaya ikan nila di Kelompok Pembudidaya Ikan (Pokdakan) Tunas Karya, Kecamatan Lingsar, Lombok Barat. Permasalahan tersebut adalah rendahnya kadar oksigen terlarut (DO = 2-3 mg/L) dalam kolam yang menyebabkan tingkat kematian ikan tinggi (18%) dan efisiensi pakan rendah (FCR 1.8). Metode kegiatan meliputi sosialisasi, pelatihan teknis, instalasi alat, serta pendampingan dan evaluasi berkala. Hasilnya menunjukkan peningkatan signifikan kadar DO menjadi 5-6 mg/L. Dampak lanjutannya adalah penurunan mortalitas di bawah 7%, peningkatan efisiensi pakan (FCR 1.4), dan pertumbuhan biomassa yang lebih baik. Selain aspek teknis, kegiatan ini juga berhasil meningkatkan kapasitas SDM kelompok melalui pelatihan dan pembentukan tim teknis internal untuk menjamin keberlanjutan. Disimpulkan bahwa teknologi aerasi microbubble venturi efektif meningkatkan produktivitas dan ekonomi budidaya ikan nila. Oleh karena itu, replikasi teknologi ini kepada kelompok pembudidaya lain sangat disarankan.

Abstract

Heavy metal present in marine water can affect aquatic organisms, particularly bivalves that function as filter feeders and therefore have a high potential to accumulate heavy metals in their bodies. Blood cockle (Anadara granosa) is one of the marine organisms commonly found in the waters of West Lombok, especially in the Lembar area, which is influenced by port activities and coastal community activities. This study aimed to analyze the concentration of lead (Pb) in blood cockles and sediments in the waters around Lembar, West Lombok, and to determine the safe consumption limit of cockles for the community. Samples of blood cockles and sediments were collected from three observation stations in Lembar waters. Each sample was collected in triplicate as replicates. The Pb concentration was analyzed using Atomic Absorption Spectrophotometry (AAS) methods and the results were compared with applicable quality standards. The results showed that the Pb concentration in blood cockles ranged from 0.043–0.051 mg/kg with an average value of 0.047 mg/kg. These values are below the maximum limit set by the government, which is 0.1 mg/kg. Meanwhile, Pb concentrations in sediments ranged from 0.887–1.32 mg/kg and were still below the sediment quality standard of 25 mg/kg. The calculation of the safe consumption limit indicated that the Maximum Tolerable Intake (MTI) of blood cockles ranged from 29-35 kg/week for adults with an average body weight of 60 kg, indicating that blood cockles from the Lembar waters are still safe for consumption.

Abstract

West Nusa Tenggara has strong aquaculture potential, particularly in freshwater catfish (Clarias sp.) farming. However, farmers in Embung Pas Hamlet, Sigerongan Village, face challenges due to limited knowledge of jaundice disease, which can lead to mass mortality and economic losses. This community service activity aimed to improve farmers’ knowledge and awareness regarding the identification, risks, prevention, and treatment of jaundice in catfish culture. The program was conducted on March 10, 2026, using a participatory approach through interactive lectures, discussions, demonstrations, and follow-up assistance. The materials included fish health management, disease symptoms, and control strategies. The results showed active participation and increased understanding among farmers, particularly in early detection and water quality management. Although minor constraints such as limited time and varying knowledge levels were encountered, the program was successfully implemented. Overall, this activity effectively enhanced farmers’ awareness and capacity in managing fish health sustainably.

Abstract

A common problem faced by betta fish breeders during the hatchery stage is the low survival rate of fry, as they are highly susceptible to changes in water quality and disease. Therefore, fry management is necessary to increase survival rates by using natural ingredients that are environmentally friendly and do not cause resistance. Ketapang leaves (Terminalia catappa) and betel leaves (Piper betle) can be used because they contain active compounds such as flavonoids, which have antimicrobial properties that can help inhibit the growth of bacteria and fungi in the water. The aim of this study was to determine the appropriate dosage of ketapang leaves and betel leaves for the survival rate of betta fry. This study used an experimental method, namely RAL with 4 treatments and 3 replications, the treatments tested were P0 (control): no treatment, P1: 1 g/l ketapang leaves, P2: 1 g/l betel leaves, P3: 0.5 g/l ketapang leaves and 0.5 g/l betel leaves. The parameters tested included absolute weight, absolute length, specific weight growth, daily length growth and survival rate. The results showed that the average absolute weight of betta fish ranged from 0.193-0.444 g, the average absolute length ranged from 2.379-3.021 cm, the average specific growth rate ranged from 0.015-0.006%/day, the average daily growth rate ranged from 0.034-0.019%/day, and the average survival rate ranged from 60.00-13.33%.
