Abstract

Usaha bidang perikanan sering mendapat kendala karena terjadi penyakit infeksi yang berakibat kematian ikan dan penggunaan antibiotik untuk mengatasi infeksi bakteri pathogen pada bidang perikanan secara terus menerus yang tidak terukur telah menyebabkankan resistansi, dan berakibat menurunnya produktifitas. Diketahui bahwa Mangrove (Rhizophora stylosa) merupakan tumbuhan yang mengandung metabolit sekunder potensial sebagai antibakteri. Tujuan dari penelitian ini untuk mendapatkan konsentrasi ekstrak (n-heksana) daun mangrove R. stylosa yang dapat menghambat pertumbuhan bakteri Vibrio spp dan A.hydrophila. Penelitian menggunakan metode eksperimental dengan Rancangan Acak Lengkap (RAL), dengan dua faktor dan  3 ulangan. Faktor perlakuan pertama adalah jenis bakteri Vibrio spp dan A. hyrdophila dan faktor perlakuan kedua adalah konsentrasi ekstrak 5000ppm,10.000ppm, 15.000 ppm, 20.000 ppm, dan kontrol positif (amoxicillin). Parameter penelitian adalah Konsentrasi Hambat Minimum (KHM) dan diameter zona hambat . Data hasil dianalisis dengan ANAVA dan bila berbeda nyata dilanjutkan dengan Uji Jarak Berganda Duncan. Hasil penelitian menunjukkan bahwa terdapat Perbedaan nyata pengaruh Jenis bakteri dan konsentrasi ekstrak n-heksana daun mangrove terhadap kontrol positif amoxicillin. Ekstrak n-heksana daun R.stylosa lebih menghambat bakteri Vibrio sp.,pada  [5000] katagori kuat dan pada [20000] katagori sangat kuat daripada  A. hydrophila [5000-15000]katagori sedang tetapi pada [20000]katagori kuat dan KHM kedua bakteri vibrio sp dan A. hydrophila terjadi pada [5000]. Dapat disimpulkan bahwa ekstrak n-heksana daun R.stylosa berpotensi sebagai antibakteri Vibrio sp. dan A. hydrophila pada ikan nila (Oreochromis niloticus).   Businesses in the fishery sector often encounter problems due to infectious diseases which result in fish death. The continuous and unmeasured use of antibiotics to treat pathogenic bacterial infections in the fisheries sector has caused resistance, and resulted in decreased productivity. Mangrove (Rhizophora stylosa) is a plant that is known to contain potential secondary metabolites as antibacterial. The purpose of this study was to obtain a concentration of extract (n-hexane) of mangrove leaves R. stylosa which could inhibit the growth of Vibrio sp. and A. hydrophila bacteria. The study used an experimental method with a completely randomized design (CRD), with two factor treantments and 3 replications. The first treatment factor was the type of bacteria Vibrio sp and A. hyrdophila and the second treatment factor was the extract concentration of 5000ppm, 10,000ppm, 15,000 ppm, 20,000ppm, and a positive control (amoxicillin). The research parameters were MIC and the diameter of the inhibition zone The result data were analyzed by ANOVA and if they were significantly different, it was continued with Duncan's Multiple Distance Test. The results show there was a significant difference in the effect of the type of bacteria and the concentration of the n-hexane extract of mangrove leaves on the positive control of amoxicillin. The n-hexane extract of leaves inhibited more Vibrio sp. bacteria, at [5000] strong category and at [20000] very strong category than A. hydrophila [5000-15000] medium category, but in [20000] strong category and MIC of both Vibrio sp and A. hydrophila bacteria occurred in [5000].. It can be concluded that the n-hexane extract of  R. stylosa leaves has the potential as an antibacterial for   Vibrio sp. and A. hydrophila in nila fish(Oreochromis niloticus).

Abstract

Rumput laut jenis Eucheuma cottonii adalah salah satu hasil perikanan yang mempunyai nilai ekonomis cukup penting karena mengandung karagenan yang merupakan bahan dasar dalam industri farmasi, makanan, maupun bahan industri lain. Mengingat besarnya permintaan pasar akan kebutuhan rumput laut maka perlu dilakukan usaha untuk meningkatkan produksinya. Namun seiring dengan meningkatnya permintaan, pembudidaya sering mengalami permasalahan antara lain bibit rumput laut yang dihasilkan belum maskimal baik dari segi jumlah maupun kualitas, sehingga perlu ada kajian untuk menghasilkan pertumbuhan benih bibit rumput laut yang baik yaitu menggunakan pupuk Conway pada media kultur rumput laut dari hasil kultur jaringan. Pupuk conway mengandung unsur nutrien yang sangat bermanfaat bagi pertumbuhan rumput laut. Penelitian ini bertujuan untuk mendapatkan dosis pupuk Conway yang tepat pada media kultur terhadap pertumbuhan bibit rumput laut E. cottonii. Penelitian ini menggunakan E.cottoni dari hasil kultur jaringan Seameo Biotrop. Penelitian ini menggunakan Rancangan Acak Lengkap dengan 5 perlakuan dan 5 ulangan yaitu dosis pupuk Conway (0, 2, 4, 6, dan 8 ml). Padat tebar E.cottoni yaitu 5 eksplan per wadah. Hasil penelitian didapatkan bahwa pemberian pupuk Conway dengan dosis berbeda berpengaruh sangat nyata (P<0.01) terhadap pertumbuhan panjang mutlak dan laju pertumbuhan spesifik, serta pertumbuhan bobot mutlak E. cottonii, dengan nilai tertinggi yaitu masing-masing 1,04 cm, 0,014%, dan 0,25 g pada perlakuan dosis pupuk Conway 8 ml. Seaweed Eucheuma cottonii is one of the fishery products that have highly important economic value because it contains carrageenan which is a basic ingredient in pharmaceuticals, food, and other industrial materials. Given the large market demand for seaweed, it is necessary to make efforts to increase production. However, along with increasing demand, cultivators often experience problems, the constraints that are often experienced are, among others, the seaweed seeds produced are not optimal both in terms of quantity and quality,  so there needs to be a study to produce good seaweed seed growth, namely using Conway fertilizer on seaweed culture media from tissue culture results. Conway fertilizer contains nutrients that are very beneficial for the growth of seaweed. This study aims to obtain the correct dosage of Conway fertilizer in culture media on the growth of E. cottonii seaweed seedlings. This study used E.cottoni from the Seameo Biotrop tissue culture. It used a completely randomized design with 5 treatments and 5 replications, namely the dose of Conway fertilizer (0, 2, 4, 6, and 8 ml). The stocking density of E. cottoni was 5 explants per container. The results showed that the application of Conway fertilizer with different doses had a very significant effect (P<0.01) on absolute length growth, specific growth rate, and absolute weight growth of E. cottonii, with the highest values of 1.04 cm, 0.014%, and 0,25 g, respectively, at the Conway fertilizer dose of 8 mL.

Abstract

Ekosistem mangrove merupakan ekosistem dengan komponen sumberdaya alam meliputi bentang alam, flora, fauna, dan masyarakat sekitar dengan beragam fungsi seperti ekologis, ekonomis dan sosial. Alih fungsi lahan mangrove untuk tambak dan pemukiman yang masif dilakukan mengakibatkan kondisi mangrove di Ujung Piring dan Teluk Awur mengalami penurunan kualitas ekosistem mangrove. Informasi spasial kondisi terkini ekosistem mangrove yang belum tersedia mengakibatkan upaya pencegahan kerusakan dan konservasi ekosistem mangrove tidak berjalan maksimal. Tujuan penelitian ini adalah mengetahui sebaran, luas, dan kondisi kesehatan mangrove di kawasan Ujung Piring dan Teluk Awur menggunakan citra Sentinel 2A melalui penginderaan jauh dan validasi lapangan. Pendekatan penginderaan jauh memadukan composite band dengan supervised classification dilakukan untuk mengetahui sebaran dan metode Normalized Difference Vegetation Index (NDVI) untuk mengetahui luas dan kondisi kesehatan mangrove. Validasi lapangan menerapkan hemispherical photography untuk menganalisa tutupan kanopi mangrove di lapangan. Hasil penelitian menunjukkan mangrove kawasan Ujung Piring tersebar di area pantai, ekowisata, dan tambak. Luas mangrove di kawasan Ujung Piring sebesar 21,004 ha terdiri dari 17,519 ha (83,41%) kategori lebat; 2,527 ha (12,03%) kategori sedang; dan 0,958 ha (4,56%) kategori jarang. Mangrove kawasan Teluk Awur dapat dijumpai di area pantai, daerah konservasi mangrove, tambak, aliran sungai, pemukiman, dan lahan terbuka. Mangrove di kawasan Teluk Awur memilki luas 10,657 ha tersusun oleh 8,013 ha (75,1% kategori lebat); 0,688 ha (6,5%) kategori sedang; dan 1,956 ha (18,4%) kategori jarang.  The mangrove ecosystem contains various natural resource components including landscapes, flora, fauna, and its surrounding communities with various ecological, economic, and social functions. Massive conversion of mangrove area for ponds and settlements has reduced the ecosystem quality of mangroves in Ujung Piring and Teluk Awur. The lack or even inexistence of spatial information regarding the current condition of the mangrove ecosystem has hindered the efforts to prevent damage and conserve mangrove ecosystem from running optimally. This research sought to examine the distribution, area, and health condition of mangroves in Ujung Piring and Teluk Awur areas using Sentinel-2A imagery by means of remote sensing and field validation. The remote sensing approach combined composite bands with supervised classification to determine the distribution and the Normalized Difference Vegetation Index (NDVI) method to determine the extent and health conditions of mangroves. The field validation applied hemispherical photography to analyze mangrove canopy cover in the field. The research results revealed that the mangroves in Ujung Piring area were distributed in coastal, ecotourism, and pond areas. The mangroves in Ujung Piring area measured 21.004 ha consisting of 17.519 ha (83.41%) in the dense category; 2,527 ha (12.03%) medium category; and 0.958 ha (4.56%) in sparse category. The mangroves in Teluk Awur area were found in coastal, mangrove conservation, pond, river, settlement, and open areas. The mangroves in Teluk Awur measured 10,657 ha consisting of 8,013 ha (75.1% dense category); 0.688 ha (6.5%) medium category; and 1,956 ha (18.4%) in sparse category.

Abstract

Spirulina platensis merupakan mikroalga yang mengandung protein tinggi. Mikroalga ini tidak hanya bertindak sebagai sumber protein sel tunggal, tetapi juga memberikan beberapa manfaat lainnya antara lain sumber karotenoid, klorofil, serta sumber mikronutrien. Salah satu kandungan karotenoid yaitu lutein. Lutein memiliki manfaat sebagai antioksidan untuk melawan radikal bebas pada mata. Pertumbuhan mikroalga dipengaruhi oleh beberapa macam faktor lingkungan, salah satunya yaitu salinitas. Penelitian ini bertujuan untuk mengetahui pengaruh salinitas terhadap kandungan lutein pada S. platensis. Metode yang digunakan ialah eksperimen laboratoris. Mikroalga S. platensis dikultivasi dengan tiga perlakuan salinitas yang berbeda yaitu 15, 23, dan 27ppt. Pertumbuhan sel S. platensis diamati selama 5 hari kemudian dipanen untuk perhitungan biomassanya. Biomassa basah hasil kultivasi diekstraksi menggunakan pelarut aseton. Ekstrak aseton S. platensis kemudian dianalisis kandungan luteinnya secara spektrofotometri. Hasil penelitian menunjukkan salinitas berbeda tidak memberikan pengaruh nyata terhadap kandungan lutein S. platensis. Kandungan pigmen lutein S. platensis yang tertinggi terdapat pada salinitas 23 ppt sebesar 0.0113 µg/g.  Spirulina platensis is a microalga that contains high protein. This microalga is not only acts as a single cell protein source, but also provides several other benefits, including a source of carotenoids, chlorophyll, and a source of micronutrients. One of the carotenoids contents is lutein. Lutein has benefits as an antioxidant to fight free radicals in the eyes. Microalgae growth is influenced by several kinds of environmental factors, one of which is salinity. This study aims to determine the effect of salinity on lutein content in S. platensis. The method used is a laboratory experiment. Microalgae S. platensis was cultivated with three different salinity treatments, namely 15, 23, and 27ppt. The growth of S. platensis cells was observed for 5 days and then harvested for biomass calculation. Wet biomass from cultivation was extracted using acetone as a solvent. The acetone extract of S. platensis was then analyzed for its lutein content spectrophotometrically. The results showed that different salinity didn’t have a significant effect on the S. platensis. The lutein content of S. platensis is highest at 23 ppt (0.0113 µg/g).

Abstract

Kegiatan pembangunan industri yang berkembang cukup pesat di kawasan industri Kabupaten Kendal diduga menjadi penyebab meningkatnya limbah buangan industri yang didalamnya terkandung logam berat timbal (Pb), sehingga limbah tersebut berkontribusi menurunkan kualitas perairan Bandengan, Kabupaten Kendal. Penelitian ini dilakukan dengan tujuan untuk mengetahui kadar logam (Pb) pada air, sedimen, dan kerang darah (A. granosa) serta batas maksimal konsumsi mingguan kerang darah (A. granosa) yang mengandung logam timbal (Pb) di Perairan Bandengan, Kabupaten Kendal. Penelitian ini dilaksanakan pada bulan Maret dan April 2022. Metode penelitian yang digunakan yaitu metode deksriptif sedangkan penentuan lokasi penelitian dengan metode purposive sampling. Analisis konsentrasi logam berat Pb dilakukan di Laboratorium Balai Besar Teknologi Pencegahan Pencemaran Industri (BBTPPI) dengan metode AAS (Atomic Absorption Spectrophotometry), sedangkan untuk analisis batas aman konsumsi mingguan dihitung dengan MTI (Maximum Tolerable Intake). Hasil penelitian ditemukan konsentrasi logam Pb di perairan Bandengan sebesar <0,003 mg/l, sedimen berkisar 15,32-24,21 mg/kg, dan kerang darah berkisar 0,209-0,731 mg/kg. Berat maksimal mengkonsumsi kerang darah (A. granosa) perminggu dari perairan Bandengan, Kabupaten Kendal individu dengan berat badan 60 kg sebesar 2,051-7,177 kg/minggu. Sedangkan, individu dengan berat 45 kg yaitu 1,538-5,382 kg/minggu. Industrial development activities have been developing quite rapidly in the Kendal Regency industrial area and are suspected to be the cause of the increase in the waste containing lead (Pb) heavy metal. It might contribute to reducing the quality of Bandengan waters. This study was to know the levels of metal (Pb) in water, sediment, and blood cockles (A. granosa) and the maximum weekly consumption of the cockles containing lead (Pb) in the waters. The study conducted in March and April 2022 used the descriptive method and purposive sampling to determine the locations. Analysis of Pb concentration was at the Laboratory of the Center for Industrial Pollution Prevention Technology (BBTPPI) using the AAS (Atomic Absorption Spectrophotometry) method. The analysis of the safe limit for weekly consumption was using the formula of MTI (Maximum Tolerable Intake). The results showed that Pb concentrations in water, sediment, and tissue in Bandengan waters were <0.003 mg/l, 15.32 - 24.21 mg/kg, and 0.209 - 0.731 mg/kg, respectively.
