Abstract

ABSTRAK

Teripang dan bulu babi adalah salah satu filum echinodermata yang terdapat dilaut, hewan ini biasanya hidup di ekosistem lamun dan terumbu karang. Kotawaringin Barat merupakan kawasan konservasi laut dan memiliki wilayah perairan salah satunya perairan desa Sungai Bakau. Selain itu, kawasan ini memiliki keanekaragaman biota-biota laut salah satunya adalah teripang dan bulu babi. Teripang dan bulu babi dikawasan ini belum teridentifikasi jenisnya dan dipublikasikan, padahal informasi ini sangat penting sebagai upaya konservasi teripang dan bulu babi di Kotawaringin Barat, oleh karena itu, perlu dilakukan penelitian tentang studi keanekaragaman teripang (Holothuridae) dan bulu babi (Echinoidea) di perairan desa Sungai Bakau Kecamatan Kumai Kabupaten Kotawaringin Barat untuk mengetahui spesies keanekaragaman teripang dan bulu babi yang ada di Perairan Desa Sungai Bakau Kecamatan Kumai Kabupaten Kotawaringin Barat serta bagaimana kualitas fisika-kimia di perairan pantai Desa Sungai Bakau Kecamatan Kumai Kabupaten Kotawaringin Barat.

Penelitian ini dilakukan pada tiga wilayah stasiun yang berbeda. Stasiun I berada di wilayah Timur, stasiun II berada di wilayah Selatan, dan stasiun III berada di wilayah Barat. Penelitian ini menggunakan pendekatan kualitatif dan jenis penelitiannya adalah survei sedangkan metode yang digunakan yaitu metode transek kuadrat dengan tekhnik purposive sampling dengan jumlah plot sebanyak 53. Sampel diidentiifikasi dan dilakukan perhitungan mengenai keanekaragaman dan dominansi serta pengukuran faktor fisika-kimia perairan.

Berdasarkan hasil penelitian didapatkan 468 individu dari 3 spesies di tiga wilayah sampling yaitu spesies teripang (Holuthuridae) yaitu 103 individu, spesies bulu babi (Lytechinus variegatus) yaitu 135 individu, dan bulu babi (Pseudoboletia Maculata) yaitu 230 individu. Nilai keanekaragaman teripang wilayah stasiun I (timur) memiliki keanekaragaman yang tinggi yaitu (0,35), stasiun II (selatan) yaitu (0,32) dan nilai keanekaragaman terendah di stasiun III yaitu (0,31). Nilai keanekaragaman bulu babi stasiun I yaitu (0,72), stasiun II (0,68), dan stasiun III (0,7). Hasil pengukuran faktor fisika-kimia perairan di kawasan pesisir desa sungai bakau pada tiga wilayah sampling yaitu pH subtrat (7), pH air (6), Suhu (30-31˚C), kecepatan arus (1,5 m/dt), intensitas cahaya (11,75) dan DO (2,03 mg/i). Hal tersebut menunjukkan nilai keanekaragaman teripang dan bulu babi dikategorikan keanekaragaman rendah sedangkan kondisi perairan di wilayah kawasan pesisir desa sungai bakau tergolong kedalam lingkungan yang ekstrim rendah sehingga berpengaruh terhadap keanekaragaman teripang dan bulu babi.

ABSTRACT

Sea Cucumber and Sea Urchin are as one genus of phyla Echinodermata, where this species usually live at sea grass ecosystem and coral reefs. Kotawaringin Barat is a sea conservation area and has coastal area where one of it is Sungai Bakau village. Mangrove river is dominated by mangrove vegetation and has sloping sand condition, sea grass ecosystem and also seaweed vegetation and coral reefs, besides its area also has variant of sea biota where one of them is Sea Cucumber and Sea Urchin. The variant of Sea Cucumber and Sea Urchin at this are have not been identified and publicized yet. Whereas the information is important as an effort of Sea Cucumber and Sea Urchin conservation at Kotawaringin Barat, to do an investigation about the varieties of Sea Cucumber (Holothuridae) and Sea Urchin (Echinoidea) in the Coastel at Sungai Bakau village of Kumai District of Kotawaringin Regency to know the varieties of Sea Cucumber and sea urchin at Sungai Bakau village of Kumai District of Kotawaringin Barat regency and also to know the quality of water chemical physic at Sungai Bakau village of Kumai District of Kotawaringin Barat regency.

This research did at three different area. First stage is at East area, second stage at South area and third area at West area. This study used qualitative approach and the type of study was survei, while the method was transact quadrate method by using purposive sampling technique on total plot of 53. The sample counting identified and done based on the varieties and domination by using the formula of Shannon-Weaver and Simpson and also by using the measurement of watering chemic-physic factor.

Based on the result found that 468 individual of 3 species on three sampling areas they were sea cucumber (Holuthuridae species) that is 103 individual, sea urchins (Lytechinus variegates species) that is 135 individual, and sea urchin (Pseudoboletia Maculata) that is 230 individual. The Varieties sea cucumber value of first station area (East) had high varieties it was (0,35), second station (South) was (0,32) and the lowest varieties at third station it was (0,31). The varieties sea urchins value of first station it was (0,72), second station was (0,68) and third station it was (0,70). The result of watering chemic-physic measurement factor at coastal area of Sungai Bakau village on three sampling areas were substrate pH (7), water pH (6), temperature (30-31oC), flowing speed (1.5 m/dt), light intensity (11.75) and DO (2.03 mg/i). It is showed that the varieties value of Sea Cucumber and Sea Urchin categorized to low varieties while the area of watering condition at coastal area of Sungai Bakau village is classified to low extreme environment which then influence the varieties of Sea Cucumber and Sea Urchin.
