In the hatchery of white shrimp larvae, there are some problems, such as a decreased water quality and diseases caused by bacteria which cause a decrease in shrimp growth. The solution to reduce these problems is by applying synbiotics. This research aimed to make an innovative synbiotic formula for the absolute length growth and survival rate of white shrimp larvae (Litopenaeus vannamei) as well as the total number of bacteria and the number of Vibrio sp. In this study, there were four treatments, as follows: C-: negative control (without synbiotic application) C+: positive control (commercial synbiotic) P: probiotic 2.5 x 105 cfu/ml and prebiotic 1,5 ppm Q: probiotic 5 x 105 cfu/ml and prebiotic 1 ppm R: probiotic 7,5 x 105 cfu/ml and prebiotic 0,5 ppm S: probiotic 106 cfu/ml and prebiotic 2 ppm, each treatment with four repetitions. This research was set up in a completely randomized design experiment using twenty-four plastic tanks with 50 L total volume filled with 20 L sterile sea water and stocked with 4,000 nauplii in the PT. Citra Larva Cemerlang hatchery, Kalianda, Lampung. Variables observed in this research were survival rate, absolute length growth, total bacterial and Vibrio sp. counts, and water quality in the white shrimp larvae (Litopenaeus vannamei). The results showed that the best survival rate is in treatment S (probiotic 106 cfu/ml and prebiotic 2 ppm) (87.7%), the highest absolute length growth is in treatment P (3.8 mm), the highest total bacteria was in treatment S (11.1 log cfu/ml), and the best total Vibrio sp. is in treatment S (3.5 log cfu/ml). Water quality of the six treatments shows results that are still in normal conditions following Indonesian National Standard SNI 7311: 2009.

Indonesia is a country that has quite large marine and fisheries resources and East Nusa Tenggara is one of the provinces in Indonesia that has very large fisheries resources, for this reason further exploration is being carried out to utilize these fisheries resources for both the domestic and export markets. This research is to find out about the marine and fisheries potential in East Nusa Tenggara and the quality of these fishery products by making direct observations at the Fish Quarantine Station for Quality Control and Safety of Fishery Products (SKIPM) Kupang, East Nusa Tenggara to find out about the fishery products that are trafficked. from the SKIPM. The results of the research show that East Nusa Tenggara has a very large and varied fisheries potential such as Anggoli, Skipjack, Cakalang, Crab Meat, Sweet Lip Fish, Grouper, Red Snapper, Onaga, Hermit crab, Mud Crab, Lobster, Beef Sei Tuna, Shark Fin, Mutira snails, Mackerel, Sea Cucumbers, Tuna Loin, Fan Shrimp, Ronggeng Shrimp, Seaweed and among these products Seaweed and Skipjack tuna are the highest number of fishery products trafficked from SKIPM Kupang, East Nusa Tenggara. The research results also show that 19 products originating from several fish processing units in East Nusa Tenggara province have met the maximum limit criteria for Escherichia coli contamination, namely <3 MPN/g with sensory pass quality or were still suitable and safe for consumption or marketing.

The sea in Indonesia covers 75% of its total land area. According to data from the Ministry of Marine Affairs and Fisheries (2019), Indonesia has approximately 5.8 million km² of water area out of a total territory of 7.81 million km². The biodiversity in Indonesia's coastal areas is utilized by coastal communities in their daily lives. Coastal resources also have potential in the health sector, such as seagrass, macroalgae, and taurine, which can be used as raw materials for natural medicine. The purpose of this study is to analyze the antioxidant potential based on the IC50 value of taurine, ethanol extracts of the seagrasses Enhalus acoroides and Cymodocea rotundata, as well as the macroalgae Padina australis and Sargassum duplicatum. The method used is the antioxidant activity assay using DPPH (2,2-Diphenyl-1-picrylhydrazyl). The results of this study indicate that, after testing with DPPH, only the ethanol extract of Cymodocea rotundata had an IC50 value of < 200 µg/mL, specifically -652.95 µg/mL, whereas the IC50 values of taurine, the ethanol extract of Enhalus acoroides, and the ethanol extracts of the macroalgae Padina australis and Sargassum duplicatum were > 200 µg/mL, indicating no antioxidant activity. In conclusion, only the ethanol extract of Cymodocea rotundata has the potential to be a candidate for antioxidant raw material.

The condition of the nest greatly determines the success of turtle egg hatching. The success of turtle egg hatching, both naturally and artificially, is influenced by several factors such as the location of the nest, the depth of the nest, vegetation conditions, environmental temperature, humidity and the surrounding environment. This study aims to see the effect of shade on the length of the incubation period and the success of green turtle egg hatching in semi-natural nests. This study was conducted at Pangumbahan Nesting Beach, Sukabumi. This study used an experimental method with the treatment of semi-natural nests placed in exposed areas and shaded areas with different depths, namely 68 (control), 30, 50, 70 and 90 cm. Measurements and observations of environmental conditions were carried out during the incubation period. Observations of hatching of hatchlings began on the 55th day of incubation and the dismantling of the entire nest was carried out on the 68th day of incubation. The results showed that in exposed areas there was no significant difference given the level of treatment on the length of the incubation period, while in sheltered or protected areas there was at least one difference in the level of treatment that had a different effect on the length of the incubation period. The fastest incubation period in exposed areas was at a depth of 30 cm and in sheltered areas was at a depth of 90 cm. Key words: incubation period, the green turtle, the success of hatching.

Lele Sangkuriang (Clarias gariepinus) merupakan salah satu komoditas perikanan yang banyak dibudidayakan karena pertumbuhannya yang cepat dan tingkat adaptasinya yang tinggi. Optimalisasi proses budidaya, terutama pada tahap pendederan, menjadi hal yang penting mengingat fase ini merupakan tahap kritis dalam pemeliharaan ikan, di mana benih lele sangkuriang rentan mengalami kematian. Penelitian ini bertujuan untuk mengetahui tingkat kelangsungan hidup lele sangkuriang yang didederkan di P2MKP Aquaculture Farm, Kabupaten Tebo, Jambi. Metode yang digunakan meliputi observasi langsung dan wawancara dengan petugas lapangan. Hasil penelitian menunjukkan bahwa setelah masa pemeliharaan, tingkat kelangsungan hidup lele sangkuriang mencapai 58,2%, dengan bobot mutlak 0,83 g dan panjang mutlak 5,60 cm. Hasil ini memberikan gambaran mengenai efektivitas sistem pendederan yang diterapkan serta dapat menjadi acuan dalam meningkatkan keberhasilan budidaya lele sangkuriang di tahap awal pemeliharaan. Kesimpulan dari penelitian ini bahwa tingkat kelangsungan hidup lele sangkuriang yang didederkan di P2MKP Aquaculture Farm, Kabupaten Tebo, Jambi tergolong baik.
