Abstrak. Besarnya potensi alam yang dimiliki oleh Kota Langsa yaitu tumbuhan mangrove dikembangkan yang nantinya dapat digunakan dalam bidang kesehatan khususnya untuk pencarian bahan baku obat-obatan seperti obat antimikroba. Selain tumbuhannya, ketersediaan makanan laut seperti kepiting bakau juga merupakan salah satu potensi lokal yang banyak diminati oleh masyarakat setempat. Namun masyarakat harus berhati-hati dalam mengkonsumsi kepiting bakau karena ada kepiting bakau yang mengandung mikroorganisme atau bakteri berbahaya yang dapat merusak kesehatan manusia baik dalam jangka pendek maupun panjang. Penelitian ini bertujuan untuk mengkaji potensi mangrove sebagai antimikroba dan mengetahui komponen bioaktif yang terdapat pada mangrove dalam mengatasi penyakit pada kepiting bakau. Pengumpulan data dilakukan dengan pengambilan sampel biji mangrove Avicennia marina dilakukan  pada Desa Kuala Langsa.  Sampel mangrove yang diambil adalah biji yang tua dan kondisinya utuh, sampel kemudian dimasukkan dalam kantong sampel ditimbang hingga beratnya 1 kg. Hasil data uji skrining fitokimia diketahui kandungan senyawa biokatif dan jenis senyawa bioaktif yang terdapat di dalam ekstraksi biji mangrove adalah triterpenenoid, tanin, fenol dan alkaloid. Pengujian daya hambat ekstrak metanol dan n-heksan biji A. marina dilakukan dengan metode difusi agar. Pada beberapa pengulangan ekstrak pelarut metanol dan n-heksan sampel biji mangrove didapatkan zona bening rata-rata 3,13 mm dan 3,03 mm dari kontrol positifnya. Hasil gejala klinis pada kepiting bakau pasca perendaman ekstrak biji tumbuhan mangrove terlihat adanya perubahan seperti mengecilnya melanosis pada karapas, memudarnya kaki renang yang memerah, dan warna karapas mulai kehijauan.Kata Kunci: antimikroba, biji mangrove, kepiting bakau Abstrak. The amount of natural potency possessed by Langsa City is developed mangrove plant which later can be used in health field especially to search for raw material of medicines like antimicrobial drug. In addition to the plants, the availability of seafood such as mangrove crab is also one of the local potential that many in demand by the local community. But people should be careful in consuming mangrove crabs because there are crabs containing microorganisms or harmful bacteria that can damage human health both in the short and long term. This study aims to assess the potential of mangrove as an antimicrobial and to know the bioactive components contained in mangrove in overcoming the disease in mangrove crab. The data was collected by sampling of mangrove seeds conducted in Kuala Langsa Village.

Kepiting bakau (Scylla  serrata  Forsskål, 1775) merupakan salah satu sumber daya hayati laut yang dipergunakan sebagai bahan baku untuk memproduksi kepiting soka. Organisme ini mempunyai nilai ekonomis penting dan banyak dibudidayakan oleh petani tradisional untuk memenuhi kebutuhan pangan baik di pasar lokal maupun ekspor. Dikeluarkannya Keputusan Menteri No 1 Tahun 2015 membuat banyak pembudidaya maupun pengekspor Kepiting Bakau mengalami banyak kerugian karena kepiting soka yang diproduksi kebanyakan tidak memenuhi syarat ukuran yang sesuai dengan ketetapan Pemerintah. Oleh karena itu untuk mengatasi permasalahan tersebut perlu dilakukan pendekatan melalui penelitian perubahan morphometri Kepiting Bakau sebelum dan setelah moulting. Penelitian ini bertujuan untuk mengetahui hubungan panjang/lebar dan berat Kepiting Bakau pada saat sebelum dan setelah moulting yang dipelihara pada lingkungan budidaya di kawasan pertambakan di Desa Mojo, Kecamatan Ulujami, Kabupaten Pemalang. Penelitian ini menggunakan Kepiting Bakau (S. serrata Forsskål, 1775), berat 80 - 150 g, dipelihara pada bok plastik (30 x 20 x 25 cm) secara seluler, padat penebaran 15 ekor per m2. Penelitian ini menggunakan metode studi kasus. Parameter penelitian ditujukan pada pengukuran morphometri tubuh Kepiting Bakau sebelum dan setelah moulting, yaitu panjang dan lebar carapace serta berat. Parameter morphometrik bagian tubuh kepiting, meliputi: hubungan panjang carapace dan pertambahan panjang carapace, hubungan lebar carapace dan pertambahan lebar carapace, hubungan berat dan pertambahan berat tubuh kepiting bakau dianalisis menggunakan analisis regresi (Sudjana, 1982). Ukuran panjang carapace, lebar carapace dan berat kepiting bakau sebelum moulting satu sama lain menunjukkan adanya pola korelasi linier positif. Pola korelasi yang sama ditunjukkan juga pada hubungan antara ukuran panjang carapace, lebar carapace dan berat Kepiting Bakau sebelum moulting dengan pertambahan panjang carapace, lebar carapace dan berat Kepiting Bakau setelah moulting. Pertumbuhan panjang carapace, lebar carapace dan berat kepiting bakau pada saat moulting masing – masing secara berurutan dicapai sebesar 12,26 % ± SD 5,57 %, 13, 65 % ± SD 3,59 %, 23,46 % ± SD 10,934 %. Dengan diketahuinya parameter tersebut dapat dipergunakan sebagai parameter penentu pemilihan ukuran Kepiting Bakau sebagai bahan baku produksi kepiting soka yang sesuai dengan ketetapan peraturan pemerintah.  Mangrove crabs (Scylla serrata Forsskål, 1775) is one of the biological resources of the sea, that is used as raw material for soft shell crab production. This organism have economically important value and has been widely cultivated by traditional farmers to meet food needs in both the local and export markets. Assigned KepMen No 1 Tahun 2015 made more mangrove crab culturer and exporter were loss in bussines because the producing soft shell crab was not apropriate with the gorverment regulation. Therefore to solve this problem was importantly done the approach through the research about the change of morphometric of mangrove crab before and after moulting.This research was aimed to know the correlation between carapace length, carapace wide and weight of mangrove crab before and after moulting thats reared in the environment culture of brackishwaterpond area in Mojo Village, Ulujami District, Pemalang Regency. This research used mangrove crab (S. serrata Forsskål, 1775), the body weight size of 80-150 g, individually kept in plastic boxes (30 x 20 x 25 cm), 15 pieces per m2 density. Research was carried out using case study method. The research parameters were aimed on the meassuring of the mangrove crab morphometric before and after moulting, such as: carapace  length, carapace wide and body weight.  Morphometric parameters of mangrove crab body, include the rellation of carapace lenght and body weight, carapace wide and body weight, carapace lenght and carapace wide were analyzed with regression metode (Sudjana, 1982). Carapace  length, carapace wide and body weight before moulting one anothers showed a regression of linier positive model. The same correlation model were showed on the correlation between carapace lenght, carapace wide and body weight of mangrove crab before moulting with the addition of carapace  length, carapace wide and body weight of mangrove crab after moulting, each following order, are: 12,26 % ± SD 5,57 %, 13, 65 % ± SD 3,59 %, 23,46 % ± SD 10,934 %. This parameter could be used as defining parameter to choose the size of mangrove crab as raw material for soft shell crab production that appropriate to the goverment regulation.

Abstract. Indarjo A, Salim G, Zein M, Septian D, Bija S. 2020. The population and mortality characteristics of mangrove crab (Scylla serrata) in the mangrove ecosystem of Tarakan City, Indonesia. Biodiversitas 21: 3856-3866. The mangrove crab is an iconic species of Tarakan City and is often is used as a souvenir. However, the high demand for this species can cause its population to decline. This study aimed to characterize the mangrove crab (Scylla serrata) population in the mangrove ecosystem of Tarakan City, North Kalimantan, Indonesia. This study was designed using a quantitative descriptive method with a case study model. The samples of mangrove crabs were obtained from 6 different stations using a purposive sampling method. The mangrove crab specimens were caught using 35-50 units of crab traps known as the ambau brackets. The primary data included carapace length, carapace width, carapace thickness, sex, and the total weight of each mangrove crab specimen. The results showed that male mangrove crabs have positive allometric growth when the condition index was fat. However, female crabs exhibited negative allometric growth when the condition index was thin. The Von Bertalanffy growth model analysis showed that the maximum carapace length of male mangrove crab in the mangrove ecosystem of Tarakan City was approximately 11.1118 cm for 189 days, while the female length was 9.6474 cm for 80 days. The total mortality value of male and female crabs was 120.01% and 154.94%, the mortality due to fishing was 84.69% and 135.75%, and natural mortality was 35.32% and 19.2%, respectively. The estimated rate of exploitation of both male and female crabs was 70.57% and 87.61%, respectively. The exploitation of S. serrata in the mangrove ecosystem of Tarakan City was evident, hence, conservation efforts are urgently required.

ABSTRACT Mangrove crab (Scylla serrata) and swimming crab (Portunus pelagicus) are economically important marine commodities produced from the coastal waters of Sangihe Islands Regency. But those marine commodity products are usually only caught accidentally with a bottom gill net. There has been a special trap fishing gear for that resources, but not known well by local fishermen. Addition of squid oil extraction baits could increase the fishing power of mangrove crab and swimming crab traps. This research aims to study the effect of squid oil extract on traps bait to catch mangrove crab and swimming crab; and identify the types of biota captured. This research was done in coastal waters of Malise village, Tabukan Tengah District of Sangihe Islands Regency for 2 weeks September 2015; based on experimental method. Six unit traps were operated ten trips where three units of them used scad mackerel bait that injected with squid oil extract, and tree other units just used scad mackerel bait without extract; and the capture data were analyzed using t test. The catch was 142 individuals (135 mangrove crabs and 7 swimming crab); where 86 crabs was caught by scad mackerel bait with squid oil extract, and 56 crabs caught with bait without squid oil extract. The analysis showed that the use of squid oil extracts on trap baits increased the catch. Keywords: mangrove crab, swimming crab,trap baits, squid oil extract, Sangihe   ABSTRAK[1] Kepiting bakau (Scylla serrata) dan rajungan (Portunus pelagicus) merupakan komoditi hasil laut ekonomis penting yang dihasilkan dari perairan pantai Kabupaten Kepulauan Sangihe. Tetapi komoditi hasil laut tersebut biasanya hanya tertangkap tanpa sengaja (by catch) dengan jaring insang dasar. Sebenarnya telah ada alat tangkap bubu khusus untuk kepiting bakau dan rajungan, tetapi belum dikenal oleh nelayan lokal. Pemberian ekstrak minyak cumi pada umpan, diduga dapat meningkatkan kemampuan tangkap dari bubu kepiting bakau dan rajungan. Penelitian ini bertujuan untuk mempelajari pengaruh ekstrak minyak cumi pada umpan bubu terhadap hasil tangkapan kepiting bakau dan rajungan, dan mengidentifikasi jenis-jenis biota yang tertangkap. Penelitian ini dilakukan di perairan Malise Kecamatan Tabukan Tengah, Kabupaten Kepulauan Sangihe; selama 2 minggu pada bulan September 2015; yang didasarkan pada metode eksperimental. Enam unit bubu dioperasikan selama sepuluh trip untuk mengumpulkan data; di mana tiga unit menggunakan umpan ikan layang yang disuntikan ekstrak minyak cumi, dan tiga unit lainnya hanya menggunakan umpan ikan laying tanpa ekstrak; dan data dianalisis dengan uji t. Tangkapan total berjumlah 142 ekor (135 ekor kepiting bakau dan 7 ekor rajungan); di mana 86 ekor tertangkap dengan umpan layang yang diberi ekstrak minyak cumi, dan 56 ekor tertangkap dengan umpan tanpa ekstrak. Hasil analisis menunjukkan bahwa penggunaan ekstrak minyak cumi pada umpan bubu, memberikan hasil tangkapan yang sangat berbeda dibandingkan dengan umpan tanpa ekstrak minyak cumi.

Ecosystem Changes

Kawasan estuari merupakan wilayah yang kaya akan unsur hara di daerah pantai. Perubahan ekosistem pantai, seperti terjadinya pendangkalan menyebabkan penurunan luasan mangrove. Dampak yang terjadi merupakan penyumbang bagi kerentanan sumberdaya kepiting bakau di daerah tersebut. Tujuan penelitian ini adalah untuk mengetahui tingkat resiko potensi kerentanan sumber daya kepiting bakau dan keberlanjutannya di estuari Sungai Mahakam Kalimantan Timur. Analisis kerentanan menggunakan perangkat lunak PSA (Productivity and Susceptibility Analysis). Hasil analisis menunjukkan bahwa potensi kepiting bakau di Eestuari Mahakam mempunyai kerentanan tingkat rendah (tingkat kerentanan =1,3). Nilai produktivitas (kemampuan pulih sumber daya) menunjukan nilai yang lebih tinggi (2,1) dari pada nilai susceptabilitas (tingkat resiko sumber daya ikan terhadap aktivitas perikanan di perairan tersebut) yaitu 1,9. Dengan kondisi tersebut maka peluang keberlanjutan ketersediaan kepiting bakau di estuari Mahakam berada dalam tingkat sedang.Estuaries constitute an extremely valuable natural resource in the coastal areas. The coastal ecosystem changes such as deforestation of the estuarine caused the decrease of mangrove forestry. These impacts directly contribute to the vulnerability of mud crab resources. The purpose of this research was to determine the risk level of potential vulnerability of mangrove crab resources in the Mahakam estuary. Vulnerability analysis using Productivity and Susceptibility Analysis (PSA) software. The results showed that mangrove crabs in the Mahakam estuary were low vulnerable (vulnerability level of 1.3). Value of productivity (the ability to recover resources) higher than susceptibility (level of risk of fish resources to fisheries activities in those areas). It, means that the chances for sustainability of mangrove crab in Mahakam estuary were medium level.
