Abstract

The research investigated the occurrences of heavy metal (Pb, Cu, and Cd) in waters, sediments, and wild shrimps collected from the Barito River estuary. Water and sediment samples were collected from 11 study sites by purposive sampling. At the same time, shrimps samples were captured around the sites. The study showed low levels of heavy metals in water samples; those were: Cd<0.0019 mg/L, Cu<0.001 mg/L, and Pb<0.0019 mg/L. Low levels of heavy metals were also detected in sediment samples, those were Cd <0.24 mg/kg, Cu <0.013-0.69 mg/kg, and Pb<0.024 mg/kg. Heavy metals contaminations were detected in Parapenaeopsis sculptilis, those were Cd = 2.802 mg/kg; Cu = 3.399 mg/kg, and Pb = 1.294 mg/kg. In Acetes japonicus, the heavy metals concentration were Cd = 2.127 mg./kg, Cu = 5.518 mg/ kg, and Pb = 2.723 mg/kg. In Penaeus merguiensi, the heavy metals concentrations were Cd = 8.598 mg/kg, Cu = 6.403 mg/kg, and Pb = 5.433 mg/kg. This study indicated the increases of heavy metals concentrations from water to sediment and finally into the shrimps. The presence of heavy metals in shrimps indicated the bioaccumulation of toxic metals, especially for Pb and Cd concentrations which exceeded the tolerable limit according to JECFA.

Abstract

Kawasan mangrove di Desa Pagatan Besar Kecamatan Takisung Kabupaten Tanah Laut memiliki potensi sebagai tujuan wisata alam. Beberapa upaya yang telah dilakukan untuk memetakan kawasan mangrove di wilayah pesisir Kalimantan Selatan, akan tetapi sangat sedikit kegiatan tersebut berhasil. Sifat biologis mangrove yang tumbuh di kawasan peralihan antara dan lautan menyebabkannya sangat rentan terhadap gangguan atau kerusakan. Mengingat pentingnya keberadaan dan peranan ekosistem hutan mangrove bagi daerah pantai sebagai kawasan ekowisata, maka penataan dan pengelolaan hutan mangrove yang sesuai dengan sifat dan karakteristiknya sangat perlu dilakukan. Dalam hal ini, salah satu upaya yang diperlukan adalah kegiatan pemetaan hutan mangrove untuk keperluan ekowisata. Untuk mendukung kegiatan tersebut, diperlukan kegiatan sosialisasi, pelatihan rehabilitasi mangrove yang dapat dilakukan oleh masyarakat agar dapat tumbuh dan berkembang sesuai yang diharapkan, sehingga kawasan ini dapat dijadikan sebagai tempat wisata yang efektif dan berkelanjutan. Metode yang digunakan dalam rangka memetakan kawasan ekosistem mangrove bersifat deskriptif dengan pendekatan partisipatif yaitu melalui pendekatan sosialisasi, penyuluhan dan pembentukan kelompok binaan, penanaman, penyulaman, hingga pemeliharaan. Hasil yang dicapai pada pengabdian ini berupa rencana pengembangan kawasan pesisir (mangrove), terwujudnya penguatan kapasitas kelembagaan, sehingga masyarakat mampu swamandiri di berbagai bidang.

Abstract

Pesisir Tanah Bumbu memiliki banyak potensi pariwisata bahari yang sangat indah yang menyediakan keragaman hayatidan keindahan pantai yang dapat menjadi tujuan utama wisatawan.Salah satu sektor pariwisata bahari KabupatenTanah Bumbu yang belum dimanfaatkan dengan baik adalah Pantai Madani. Pantai ini memiliki panorama pantai yang sangat indah dan menarik. Potensi ini harus terus didorong agar meningkatkan kunjungan wisatawan baik lokal, domestik maupun luar negeri.Penelitian ini bertujuan untuk mengukur kekuatan parameter fisik (physical attribute) di perairan kawasan Pantai Madani sebagai salah satu indikator dalam penilaian kelayakan kawasan wisata Pantai.Metode pengujian dan analisis konsentrasi parameter fisik diuji berdasarkan baku mutu kualitas air untuk pariwisata bahari Menteri Lingkungan Hidup Keputusan No.51/MENLH/2004 tentang baku mutu air laut, pengujian dan analisis konsentrasi amoniak berdasarkan SNI 19-6964.3-2003.Hasil pengujian dibandingkan dengan nilai baku mutu yang sudah ditetapkan. Faktor utama yang diamati dianalisis menggunakan metode recreation opportunity spectrum.Hasil penghitungan tiga parameter utama (fisik, pengelolaan dan sosial) menunjukkan bahwa parameter fisik merupakan parameter yang memiliki nilai paling tinggi mengartikan bahwa parameter tersebut merupakan spektrum peluang pengembangan yang harus dipertahankan.
PENGARUH LAMA WAKTU PENGGARAMAN YANG BERBEDA TERHADAP KADAR PROTEIN DAN ASAM AMINO CUMI-CUMI (LOLIGO SP.) Rabiatul Adawyah; Ulil Amri; Widya Ramadhini; El Redha El Redha; Findya Puspitasari

Abstract

Cumi-cumi (Loligo sp.) merupakan binatang lunak dengan tubuh berbentuk silindris. Sirip-siripnya berbentuk triangular atau radar yang menjadi satu pada ujungnya. Pada kepalanya disekitar lubang mulutnya terdapat 10 tentakel yang dilengkapi dengan alat penghisap (sucker) dan merupakan sumber protein hewani yang mana komponen utama penyusun proteinnya adalah asam amino. Penelitian ini bertujuan untuk mengetahui pengaruh lama waktu penggaraman yang berbeda pada proses pengolahan cumi-cumi terhadap kadar protein dan profil asam amino. Hasil penelitian menunjukkan bahwa perlakuan lama waktu penggaraman yang berbeda memberikan pengaruh yang tidak berbeda nyata terhadap kadar protein berdasarkan hasil Analysis of Variance (ANOVA) α 5%. Kesimpulan dari penelitian ini adalah pengaruh lama waktu penggaraman cumi yang berbeda tidak berpengaruh terhadap kadar protein, Hasil analisa kadar protein tertinggi ada pada perlakuan C yaitu penggaraman selama 5 hari sebesar 15,09% sedangkan untuk profil asam amino lisin sebesar 1,38% dari perlakuan 0 yaitu cumi-cumi segar merupakan jenis asam amino esensial tertinggi dari profil asam amino penyusun protein cumi, sedangkan jenis asam amino non esensial tertinggi adalah asam glutamat sebesar 2,79% dari perlakuan 0 yaitu cumi-cumi segar. The squid (Loligo sp.) Is a soft animal with a cylindrical body. The fins are triangular or radar-shaped which are joined at the ends. On the head around the mouth opening there are 10 tentacles which are equipped with a sucker (sucker) and are a source of animal protein where the main component of protein is amino acids. This study aims to determine the effect of different salting times in the processing of squid on protein content and amino acid profile. The results showed that the different salting time treatments had no significant effect on protein content based on the results of the Analysis of Variance (ANOVA) α 5%. The conclusion of this study is that the effect of different salting time of squid has no effect on protein content.The results of the analysis of the highest protein content were in treatment C, namely salting for 5 days at 15.09%, while for the lysine amino acid profile of 1.38% of the treatment. 0, namely fresh squid is the highest type of essential amino acid from the amino acid profile of squid protein, while the highest type of non-essential amino acid is glutamic acid at 2.79% from treatment 0, namely fresh squid.

Abstract

North Aru Island’s offshore had a long exploration history since 1973 until present. The characteristics of seabed can be studied through the shapes, acoustic reflection pattern, type of substrate or sediment, or by living organisms at the seafloor. In Indonesia, the sub-bottom profiler data was previously only used to measure sea depth. This study was expected to provide overview and updated information about sea depth, seabed and sedimentary layers characteristics based on generated acoustical reflection values and to identify information about abiotic compounding seabed (grain size) used methods Folk 1974 and Spread. Resulted bathymetry data could explain the depth and topography of study areas, seabed characteristics, sea bed sediment classification that were expected to support the determination of shipping tracked lines, underwater pipelines construction, and to determine mineral compounds in the deep sea. The obtained data of field records were in digital *.odc format that is a standard format for BATHY-2010 software. In order to simplify data processing, there would be a series data conversion process into other formats. Data processing of sub-bottom profiling was conducted by Kogeo-imaging software. For more clear and better look than the playback data, the processing data was undergone some steps of treatments such as filtering, stacking and additional gain. Moreover, those data were interpreted at once time with digitizing to interpreted sediment layers. The sea depth of research location was around 52.59-97.03 below the sea surface. Sea bottom formed land (flat) was in the eastern part of the location. Steep basin or Aru Trough was in the western with type substrate of gravelly mud. In general, recorded seismic cut (section) was in the time domain which created vertical velocity distortion and lateral that would produce seismic records that would be different with its actual. Seismic only enabled to detect lithology border if there any acoustical impedance exchange which would be bigger than detectable limit of used seismic waves.
