Abstract

This study investigates the abundance and diversity of bacteria associated with two intertidal seaweeds, Sargassum sp. and Kappaphycus alvarezii, in Ekas Bay. Intertidal zones are dynamic environments where seaweeds and their associated microbial communities play crucial roles in ecological processes. Seaweeds host a variety of bacteria that contribute to nutrient cycling, seaweed health, and overall ecosystem function. The primary variable measured in this study was the bacterial abundance, expressed as Colony Forming Units per milliliter (CFU/mL). The conclusion of these findings has positive implications for the environmental health around the floating raft, base stakes, Sargassum sp. and Kappaphycus alverazii. The absence of harmful bacteria supports the sustainability of aquatic ecosystems and can provide positive benefits for the species inhabiting those areas.

Abstract

Ekas Bay is a semi-enclosed bay and estuary in the southern part of Lombok Island. Ekas Bay has an area of 5,312.68 hectares, although it is not very wide, this bay has its own uniqueness and is relatively protected from waves because it is located inland. In Ekas Bay itself, two river estuaries are found, namely the Awang River Estuary and the Kelongkong River Estuary. The existence of these two river estuaries has a negative impact on the condition of the waters of Ekas Bay because residue from household activities is carried away by the river current, one of which is plastic waste. The presence of microplastics on ocean coasts has a negative impact on sea water quality and the life of marine biota, microplastics cannot evaporate or degrade by themselves, microplastics will accumulate in sea water and the body parts of marine biota. This research aims to identify the type and abundance of microplastics in the Ekas Bay floating net cage area and the results obtained in water samples were that the abundance of microplastics at point A was 49.44 par/L, point B was 55.76 par/L and point C was 40.40 par /L. The abundance of microplastics in sediment samples at point A was 12.25 par/L, point B was 10.8 par/L and point C was 11.01 par/L.

Abstract

Freshwater prawn (Macrobrachium rosenbergii) is a freshwater species which intensively cultivated. Calcium (Ca) and magnesium (Mg) are crucial factors supporting the biological and physiological activities of freshwater prawns. The presence of calcium and magnesium minerals in the environment is utilized by the prawns, especially after the molting process. Calcium and magnesium play roles in osmoregulation and the formation of the prawn's carapace. This study aims to determine the optimal ratio of calcium and magnesium minerals to support molting frequency, specific growth rate, survival rate, and feed efficiency.The experimental design used in this research is a completely randomized design (CRD) with five treatments and three replicates. The treatment given consisted of increasing Ca-Mg in the media: A: 30 mg l-1 Ca + 0 mg l-1 Mg (1:0); B: 30 mg l-1 Ca + 15 mg l-1 Mg (1:0.5); C: 30 mg l-1 Ca + 30 mg l-1 Mg (1:1); D: 30 mg l-1 Ca + 45 mg l-1 Mg (1:1.5) and E: 30 mg l-1 Ca + 60 mg l-1 Mg (1:2). Based on the result, treatment C: 30 mg l-1 Ca + 30 mg l-1 Mg (1:1) was found to improve molting frequency, growth rate, feed efficiency and survival rate.

Abstract

This study investigates microplastic contamination in whiteleg shrimp (Litopenaeus vannamei) cultivation systems, focusing on water, feed, and shrimp health. Microplastics, which pose significant threats to aquaculture, are often ingested by shrimp, potentially causing physiological damage and reducing product quality. The research was conducted from June to September 2024 at PT—X in North Lombok Regency. Samples of water, shrimp organs (intestines, stomach, and gills), and feed (pellets and crumbles) were analyzed for microplastic contamination. Results revealed a high presence of microplastic fragments in both shrimp and feed, with a significant reduction in microplastic particles after water filtration treatment. Specifically, the water reservoir contained 71 microplastic particles before treatment, with fragments being the most prevalent, and decreased to 8 particles post-treatment. The pelleted feed showed 102 microplastic particles, with fragments comprising 90 of them. Similarly, crumble feed contained 49 microplastic particles, predominantly fragments. The findings emphasize the significant role of microplastic pollution from the surrounding environment and the feed production process in shrimp farming. This study provides essential insights into the sources and impact of microplastics on shrimp health and the quality of aquaculture products, advocating for improved management practices and environmental awareness to mitigate contamination risks.

Abstract

Color enhancement in ornamental fish is an essential quality parameter that directly influences market value and consumer preference. Natural pigments derived from marine resources, such as seaweed, offer a sustainable alternative to synthetic color enhancers. This study aimed to determine the effect of seaweed meal (Eucheuma cottonii) on the color brightness of goldfish (Carassius auratus). Goldfish used had an initial weight of 10.12 ± 0.06 g and an initial length of 5.08 ± 0.02 cm. Fish were fed using the ad libitum method three times daily with four feed treatments: P1 (Control), P2 (4 g seaweed meal), P3 (8 g seaweed meal), and P4 (12 g seaweed meal). The study was conducted for 45 days to evaluate growth performance and color characteristics. A completely randomized design with four treatments and three replications was applied. Data were analyzed using one-way ANOVA at a 95% confidence level (p < 0.05). Results showed that the addition of seaweed meal significantly influenced the red hue variable in goldfish. Brightness showed no significant difference among treatments, with the highest value in P4 (55.88%) and the lowest in P3 (52.68%). The red hue differed significantly, with the highest value in P3 (16.96%) and the lowest in P1 (9.13%). The yellow hue showed no significant difference, with values ranging from 36.68% (P1) to 38.43% (P2). Overall, supplementation with 8 g of seaweed meal effectively enhanced the visual red hue of goldfish.

Abstract

Penelitian ini bertujuan untuk menganalisis komposisi dan kelimpahan fitoplankton sebagai bioindikator kesesuaian lingkungan pada sistem budidaya polikultur lobster pasir (Panulirus homarus) dan ikan baronang (Siganus sp.) dalam keramba jaring apung (KJA). Fitoplankton berperan penting dalam menjaga stabilitas ekosistem perairan serta mencerminkan kondisi kualitas air melalui perubahan struktur komunitasnya. Pengambilan sampel dilakukan pada 3 titik di sekitar KJA menggunakan metode purposive sampling. Parameter yang diamati meliputi kelimpahan, keanekaragaman, dominansi, serta indeks keseragaman, yang dianalisis secara deskriptif untuk menilai kondisi perairan. Hasil penelitian menunjukkan bahwa kelimpahan fitoplankton termasuk dalam eutrofik, keanekaragaman (H’) sedang, keseragaman (E) tinggi dan indeks dominasi (D) yang rendah. Faktor luar terjadinya eutrofikasi dalam suatu perairan salah satunya adalah kegiatan budidaya dengan menggunakan sistem KJA. Fitoplankton dari kelas Bacillariphyceae ditemukan paling banyak yaitu dari spesies Rhizosolenia sp. dan Synedra sp. Beberapa penelitian menunjukkan kedua spesies tersebut secara alami ditemukan pada isi lambung lobster dan merupakan pakan alami lobster pasir dan ikan baronang. Nilai parameter fisika dan kimia kualitas air menunjukkan perairan KJA Ujung Betok masih dalam kondisi layak untuk kegiatan budidaya.  Berdasarkan analisis bioindikator dan kondisi fisika kimia perairan, KJA Ujung Betok sesuai untuk budidaya polikultur lobster pasir dan ikan baronang.

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

The development of stable and palatable artificial feed remains a major challenge in the culture of Asian swamp eel (Monopterus albus), mainly due to the continued reliance on natural feeds such as earthworms. This study evaluated the effects of different binder types and concentrations on feed stability and eel feeding responses using pasta feed formulations combining commercial pellets and earthworms. The experiment applied a factorial Completely Randomized Design involving four binder types—gelatin, gluten, carboxymethyl cellulose, and chitosan—with several concentration levels (10%, 15%, and 20%) including a control without binder. Feed stability was assessed through water immersion tests measuring feed disintegration and structural deformation, while feeding behavior was evaluated through approach frequency, consumption, rejection behavior, and feeding latency. The results showed that binder incorporation significantly improved feed stability compared with the control treatment. Chitosan at a 10% concentration provided the best resistance to feed breakage, whereas 10% of carboxymethyl cellulose, gluten, and chitosan, maintained feed structure effectively during immersion. Binder-containing feeds, particularly those with gelatin, gluten, and chitosan, exhibited no different in feeding acceptance. These findings demonstrate that optimizing binder type and concentration can improve feed stability and feeding efficiency, supporting the development of more sustainable artificial feeds for swamp eel aquaculture.
