Abstract

AbstrakPelabuhan Perikanan Samudera (PPS) Kendari merupakan salah satu pelabuhan perikanan terbesar di Sulawesi. Banyaknya kapal-kapal yang berlabuh di PPS Kendari membuat banyak pula buangan sampah dan tumpahan minyak - minyak bekas yang masuk ke perairan laut. Buangan-buangan tersebut mengakibatkan terjadinya perubahan kualitas perairan. Penelitian ini bertujuan untuk mengetahui kondisi kualitas air berdasarkan parameter fisika dan parameter kimia di PPS Kendari. Penelitian ini diharapkan dapat bermanfaat bagi pengelolaan wilayah pesisir khususnya Pelabuhan Perikanan Samudera. Penentuan stasiun penelitian berdasarkan aspek keterwakilan pengaruh akibat aktivitas industri dan PPS yaitu, Stasiun 1 berada di dermaga PPS dimana dijadikan sebagai tempat berlabuhnya kapal dan tempat pembongkaran hasil tangkapan. Stasiun 2, berada di muara instalasi pembuangan limbah (IPAL) PPS Kendari. Parameter lingkungan yang diukur meliputi suhu, padatan tersuspensi, pH, salinitas, oksigen terlarut, nitrat, fosfat. Hasil penelitian menunjukkan bahwa kondisi kualitas air PPS Kendari ditinjau dari parameter fisika dan kimia berdasarkan KepMen LH No. 51 Tahun 2004 sudah melebihi baku mutu air terutama untuk suhu, salinitas, oksigen terlarut dan fosfat.

Abstract

Perairan Asia Tenggara dan sekitarnya memiliki variabilitas laut-atmosfer yang besar akibat dari fluktuasi parameter oseanografi yang berasal dari perairan Samudera Pasifik dan Samudera Hindia pada arah zonal dan pada arah meridional berasal dari Laut Cina Selatan, perairan utara dan selatan Jawa dan perairan barat Australia. Fenomena yang dominan mempengaruhi variabilitas laut-atmosfer di wilayah Asia Tenggara dan sekitarnya adalah Muson, Dipole Mode (DM) dan El Nino Southern Oscillation (ENSO) dengan siklus waktu dari musiman sampai antar tahunan. Penelitian sebelumnya yang dilakukan lebih banyak mengkaji Muson, DM dan ENSO secara individu dari fenomenanya itu sendiri, tidak secara komprehensif mengarah kepada kemungkinan adanya interaksi satu sama lain. Tujuan dari penelitian ini adalah mengkaji variabilitas lautatmosfer dan proses dinamika interaksi antara Muson, DM dan ENSO secara simultan terhadap curah hujan di Propinsi Lampung. Analisis data yang digunakan pada penelitian ini dengan pendekatan metode yang dapat mendekomposisi sinyal tersebut baik pada skala ruang maupun waktu dari hasil interaksi antara Muson, DM dan ENSO. Analisis yang digunakan meliputi transformasi wavelet kontinyu dan korelasi silang transformasi wavelet. Dari analisis transformasi wavelet kontinu, koherensi maupun transformasi silang diperoleh kesimpulan bahwa pola curah hujan di wilayah lampung sangat dipengaruhi oleh pengaruh musiman atau adanya pengaruh WNPMI dibandingkan dengan pengaruh DMI dan SOI, akan tetapi arah fase yang berlawanan menunjukkan adanya pola pergantian pengaruh yang terjadi. DMI berpengaruh pada periode 6 bulanan, sedangakan SOI berpengaruh pada fase 12 bulanan

Abstract

Coconut crab (Birgus latro) is  one of the species of crustaceans that economically valuable. The research aimed to investigate habitat characteristics and gonad maturity of Coconut crabs (Birgus latro) in Uta Island, North Mollucas. Sampling was conducted through cruising survey from May to September 2012, while parameters examined to the habitat characteristics and reproductive aspects were physical-chemical, gonad maturity, and vegetation existence. Habitat characteristics were assessed using Cluster Analysis. Result showed that length and weight relationship of male crabs wasW= 1.93 (CP + r), while the female was 1.17W= 1.97 (CP + r) 0.97. During the observation, it showed that mature gonad occurred in all catching time indicating that it didn’t occur simultaneously on the broodstock. The smallest crabs were found 65.44 mm in length (CP + r). There was no significant different of sex ratio between males and females (1:1). Disparity of habitat characteristics in each station doesn’t affect to the catch, both the quantity and level of gonad maturity. Habitat conditions at all stations strongly supported their activities to live sustainably.
