Abstract

Kondisi perairan Teluk Kendari saat ini semakin memprihatinkan, padahal kawasan perairan ini merupakan pelabuhan utama di Provinsi Sulawesi Tenggara. Daerah Aliran Sungai (DAS) Wanggu seluas 339,73 km² merupakan DAS penyumbang sedimen terbesar di perairan Teluk Kendari, dengan laju sedimentasi yang semakin meningkat. Kondisi iniakan menyebabkan terjadinya ancaman terhadap kualitas air untuk biota laut dan lingkungan sekitarnya. Penelitian ini bertujuan menganalisis pola sebaran kualitas air laut berdasarkan KepMen LH No.51 Tahun 2004 tentang baku mutu untuk biota laut. Penelitian dilaksanakan pada bulan Juni 2015 berdasarkan parameter nilai pH, DO, kekeruhan dan salinitas yang diukur menggunakan alat Water Quality Checker TOA DKK di 25 stasiun titik pengamatan. Data – data yang diperoleh kemudian disesuaikan dengan baku mutu air untuk biota laut dan selanjutnya dilakukan analisis dengan pendekatan spasial menggunakan Sistem Informasi Geografis (SIG). Hasil yang diperoleh menunjukan nilai pH berkisar antara 8,64 – 8,96 ini berarti kondisi pH berada pada kondisi tidak sesuai untuk biota laut, nilai DO berkisar antara 6,57 – 7,29 mg/l ini berarti kondisi DO berada pada kondisi sesuai untuk biota laut, sedangkan nilai salinitas berkisar antara 11,2-33,5% ini berarti pada stasiun 3, 24 dan 25 berada pada kondisi sesuai untuk biota laut dannilai kekeruhan berkisar 1,8 – 64,4 ntu, ini berarti nilai kekeruhan pada stasiun 8, 10, 11, dan 22 berada pada kondisi sesuai untuk biota laut.KATA KUNCI: Biota laut, kualitas air laut, Teluk Kendari.

Abstract

Komplek Pelabuhan Perikanan Samudera (PPS) Bungus merupakan kawasan pelabuhan perikanan terpadu klas Samudera yang berbatasan dengan laut (Selat Mentawai) dan dilalui sungai kecil dengan area persawahan disekitarnya. Terdapat beberapa fasilitas di komplek PPS Bungus yaitu pelabuhan perikanan, pengawasan perairan, penelitian, industri pengolahan perikanan, permukiman dan lain-lain. Beragam kegiatan yang ada tentu berdampak pada perairan yang ada. Tujuan penelitian ini adalah untuk mengetahui status air berdasarkan metode indeks golongan air. Hasil analisa berdasarkan PP No.82 Tahun 2001 yang dilakukan terhadap golongan air di muara sungai dan outlet menunjukkan bahwa kondisi perairan termasuk Klas IV atau untuk pertanian dan industri, sedangkan di sekitar dermaga, perairan termasuk Klas III, untuk perikanan. Kelas indeks air berdasarkan Kepmen LH No.115 Tahun 2003 menunjukkan bahwa muara sungai, outlet dan dermaga berstatus tidak tercemar. Hasil analisa terhadap perairan untuk Klas IV menunjukkan indeks 0,780 di muara sungai dan 0,712 di outlet, sedangkan di dermaga menunjukkan indeks 0,794 atau Klas III. Beberapa parameter air seperti turbiditas, BOD dan Cd di muara dan outlet sedikit melebihi baku mutu namun masih dalam batas toleransi (Kepmen LH No.51 Tahun 2004). Ditinjau dari segi kualitas air terhadap aktivitas industri berdasarkan Permen Lingkungan Hidup No.3 Tahun 2010 tentang baku mutu air limbah di kawasan industri (outlet) untuk parameter COD, pH, TSS, Selenium dan Tembaga menunjukkan hasil sesuai baku mutu.

Abstract

Climate change and global warming have a negative impact on coastal, especially small islands. Abration and floods can be very danger and need response to minimize the disaster risks. A simple and practical method is needed to inform the location and type of coastal vulnerability and its risks along coastal segments. Smartline is a coastal management method that represents the geomorphology of coastal, hinterland and shoreline. The North Pagai is a small island, a part of the Mentawai Islands that located at the west offshore of Sumatra Island and one of the under developed areas in Indonesia. The island is surrounded by the Hindia Ocean and located on a subduction path of tectonic plate that prone to earthquakes and Tsunami. High rainfall, strong winds, the complexity of coastal morphology and also the majority of coastal residents and limited infrastructure make the problems more complicated. Tsunami in 2010 (7.7 Mw) caused the change of shoreline getting worst on The East Coast of The North Pagai Island. This study aims to identify the coastal vulnerability using Smartline method. The research was conducted on April and September 2016. The result concludes that physical aspect shows Saumangaya and Matobe Village at high and also very high level of vulnerability hence Sikakap Village at very high level. The socio-economic aspect shows that The Sikakap Village is more advanced but contrary more vulnerable to disaster in terms of population density and complex activities. The North Pagai Island is a vulnerable island from physical and socio-economic aspects.

Abstract

Abstract. The marine sediment is important indicator of the seafloor. The characteristics of marine sediments can be seen from grain size, type and Total Dissolved Solid (TDS). Sediments derived from organic and non-organic particles are carried by the sea currents, waves, streams and tidal process in the coastal areas. At very high levels, sediments can cause pollution or vulnerability such as decreasing of dissolved oxygen, coral bleaching, and increased the eurotrification processes. Pagai Strait is located between North Pagai Island and South Pagai. This strait has enormous potential and it is used by the surrounding community for various activities such as port and sea transportation, fishery, marine aquaculture and tourism. This study aims to determine the characteristics of sediment in Pagai Strait. The field survey was conducted in September 2016 for waves, currents, water quality and sediment samples with purposive sampling method. The results showed that the average of sediments in Pagai Strait is D35 sized 0.155 mm; D50 sized 0.273 mm; and D90 sized 1.574 mm with specific gravity 2.665 gr/cm3 and dominated by sand 66.88%. TDS between 51.6 to 55.0 mg/L, appropriate for port and mangrove. Scale of sediment, A = 0.119 and sediment velocity is 0.002 m/s. Sediment transport approximately is 0.389 m3/day.
