Whiteleg shrimp (Litopenaeus vannamei) is a fisheries commodity which has high economic value because of its high demand and easier cultivation. Lamongan regency is one of the minapolitan region in East Java Province, especially at Glagah district, Jatirenggo village which becomes the minapolist, with one of the superior commodities is whiteleg shrimp. The development of a certain village can be determined by village developing index or IDM which consists of three categories, they are left behind, developing, and advance village. Jatirenggo village has a village developing index (IDM) of 0.6080 which classified as developing category or category 2. Thus, in order to increase its status, the welfare of its people need to be considered. Whiteleg shrimp pond aquaculture can be one of the effort to increase the income of Jatirenggoâ€™s. This study aims to analyze the sustainability of whiteleg shrimp aquaculture activity in Jatirenggo village according to ecology, socio-economic, technology-infrastructure, and institutional dimension. The used method was MDS Rapfish. The results showed that the whiteleg shrimp aquaculture in Jatirenggo village is classified as sustainable, or it means the situation in Jatirenggo village is suitable for a successful aquaculture. Thus, it can be expected to increase the income of the farmers.Â Â

Ikan sidat (Anguilla sp.) merupakan jenis ikan yang mempunyai nilai permintaan ekspor yang tinggi di Indonesia. Tetapi pada tahun 2011 volume ekspor menurun sebesar 39.1% yang diakibatkan oleh lambatnya laju pertumbuhan karena rendahnya daya cerna protein, karbohidrat dan lemak dalam pakan oleh sidat. Pemeriksaan histopatologi merupakan salah satu cara dalam mendiagnosa adanya perubahan sel dalam jaringan ikan. Metode yang digunakan yaitu eksperimental dengan dosis probiotik yang berbeda 10 ml/kg; 15 ml/kg; 20 ml/kg dan 25 ml/kg dan penambahan minyak ikan masing-masing 5%. Dari hasil penelitian, nilai skoring kerusakan histopatologi lambung terendah pada perlakuan dosis 15 ml/kg diperoleh rata-rata dan standart deviasi kerusakan jaringan sebesar (1.40Â±0.20) radang; (1.27Â±0.23) kongesti dan (1.53Â±0.43) nekrosis. Sedangkan nilai makrofag tertinggi pada dosis 15ml/kg dengan nilai 2.13Â±0.31 sehingga dapat disimpulkan bahwa nilai tersebut mampu memberikan perbedaan yang signifikan terhadap histopatologi lambung pada ikan sidat (Anguilla sp.) selama masa pemeliharaan. Penggunaan probitoik dapat menurunkan resiko kerusakan histopatologi lambung ikan sidat dan dapat lebih efektif meningkatkan daya cerna ikan sidat sehingga dapat diaplikasikan pada budidaya ikan sidat (Anguilla sp.) dengan dosis 15ml/kg dan minyak ikan 5% pada pellet guna meminimalisir kerusakan jaringan pada sel.Kata kunci: Ikan sidat, Kesehatan ikan, Probiotik, Histopatologi

C. vulgaris is photoautotrophic, which refers to microalgae that require light as an energy source. One of the light sources used to affect pigments in microalgae is UV light. The advantage of UV light is that it can change gene composition, which results in mutant genes in biopigment mutations and causes a higher number of activities compared to the natural ones, thereby increasing the growth, carotenoids, and chlorophyll-a of microalgae. The aim of this research is to determine the effect of oxidation stress of UV light on growth, carotenoids and chlorophyll-a content of Chlorella vulgaris. The treatments were given based on differences in the power of the UV-C light from, 8W, 15W and 30W. This study used the UV-Vis Spectrophotometer method was used to calculate growth, carotenoids and chlorophyll-a. Data were analysed using ANOVA test, Duncan's Multiple Range Test, and Principal Component Analysis (PCA). The results showed a significant effect of UV-C light. The best treatment was found in the administration of 30 W UV light, with the results of growth was 4.7746 × 106 cells/ml, content of carotenoids was 1.75 mg/ml and chlorophyll-a was 4.67 mg/ml of C. vulgaris. Biopigment can absorb radiation from UV-C light, which causes these microalgae to survive in environmental stress conditions. Absorbed light can affect the spectrum of pigments, thereby increasing growth, carotenoids, and chlorophyll-a.

Diatom, Bacillariophyceae, has an important role in environmental support because these algae contribute to 25% of the oxygen supply globally and each year represent 40% of primary production by fixed carbon using photosynthesis. Diatom samples were obtained from 3 different sites in around NRPS. Cleaning diatoms analyzed using SEM for describe ultrastructure in diatom valves. Three dominant diatoms Cocconeidaceae and Bacillariaceae from the south Java Sea (Indian Ocean). Basic information regarding the diversity of diatoms, and the success of photoautotrophic micro-algae that can be found both in marine and freshwater habitats, is very important to describe the role of each taxon from an ecology perspective in the future. Samples are taken from the substrate of 3 stations in Nature Reserve Pulau Sempu and prepared in the laboratory for scanning electron microscopy photographs. Clear and detailed features diatom frustule of SEM photograph reveal a schild diatom (Cocconeis) and panduriform diatom (Psammodictyon) are dominating taxa in NRSP areas.Keywords:Hard coralCocconeisPsammodictyonPulau SempuDiatom

Kawasan pesisir Jawa Timur memiliki beberapa lokasi pendaratan dan peneluran penyu, akan tetapi pada saat ini belum terdapat data komprehensif yang menggambarkan kondisi dan sensitivitas kawasan tersebut terhadap ancaman perubahan iklim. Fenomena cuaca ekstrim di Samudera Hindia timur pada kurun waktu 2016 â€“ 2018 diduga memberikan dampak terhadap pantai peneluran penyu di pesisir Jawa Timur. Penelitian ini dilakukan untuk mengidentifikasi kondisi fisik dan pengelolaan pada 6 lokasi utama peneluran penyu di pesisir Jawa Timur. Taman Nasional Alas Purwo dan Taman Nasional Meru Betiri merupakan kawasan konservasi penyu yang dikelola oleh pemerintah, sedangkan lokasi lainnya merupakan lokasi peneluran penyu yang dikonservasi oleh kelompok masyarakat, diantaranya Pantai Taman Ria (Pacitan), Pantai Kili Kili (Trenggalek), Pantai Pathuk Gebang (Tulungagung) dan Pantai Bajulmati (Malang). Kegiatan observasi lapangan dilaksanakan pada Tahun 2017 dan 2018. Variabel pengamatan meliputi perubahan fisik pantai akibat cuaca ekstrim, sementara analisis komponen eksposur dan sensitivitas habitat didapatkan dari pengukuran variabel temperatur substrat, serta event siklon dan anomali SPL. Hasil penelitian menunjukkan cuaca ekstrim berupa gelombang tinggi dan banjir pasang yang menyebabkan adanya fitur abrasi dan pergeseran lokasi peneluran pada pantai pendaratan penyu. Curah hujan yang tinggi pada musim peneluran menyebabkan suhu substrat berada pada rentang bawah pivot (25 â€“ 28â—¦C) dengan kelembaban bervariasi. Walaupun begitu, belum terdapat bentuk manajemen adaptif terhadap perubahan iklim pada seluruh area konservasi penyu di Jawa Timur.Â

Microalgae, micro-sized plant organisms, play a crucial role in aquatic ecosystems. While many microalgae inhabit substrates or the bottom of water bodies, several types are planktonic. This study aimed to identify the types and abundance of microalgae in both sediment and water column habitats, as well as to analyse the environmental factors influencing their abundance. The research encompasses observations of water quality factors, microalgae abundance, relative abundance, diversity index, evenness index, and dominance index. Statistical analyses were using non-metric multidimensional scaling (NMDS) and Canonical Correspondence Analysis (CCA). The study was conducted in May-June 2022, with bi-weekly sampling at three points within each location for two months. Microalgae identified in the coastal area of Probolinggo belong to the Bacillariophyceae, Cyanophyceae, and Chlorophyceae classes. The highest microalgae abundance in sediment habitat was 58,472 ind/cm2, while in the water column was 4,118 ind/l. Diversity, evenness, and dominance indices in both sediment and water column habitats ranged from 1.93 to 2.61, 0.88 to 0.98, and 0.09 to 0.10, respectively. NMDS and CCA analyses indicate a graphical representation of the Bacillariophyceae class, demonstrating its prevalence across all sites.
