Abstract

Sea cucumbers are an Indonesian fisheries export commodity. Sea cucumber populations that are endangered in nature encourage sea cucumbers to be produced through hatchery and nursery. Through nursery, it is expected that sea cucumber juveniles are stronger and can increase survival rate when stocked in growth containers or restocked. This study aims to provide better sandfish nursery techniques and local area characteristics to support hatchery activities. This study was conducted in May - July 2018 at the Hatchery CV Pesona Manir Rat, Southeast Maluku Regency. Juvenile sandfish 30-36 days old, rearing in hapa measuring 100 x 100 x 70 cm with a density of 200 individuals/hapa. In one tank rearing is placed one hapa. During rearing, 100-150% of water is changed and given one-liter Navicular sp. every day. Aeration was installed 4 points on each hapa and water quality measurement was conducted every day. At the end of the study, body length measurements and mortality calculations were conducted. The result is that sea cucumber juvenile which is maintained has absolute growth ranging from 1.98 to 2.1 cm with an average absolute growth of 2.03 cm. The average mortality obtained was 53.83% with a range of 53% - 55%. Based on the discussion it was concluded that this technique can be applied in sandfish nursery. ABSTRAKTeripang merupakan komuditi eksport perikanan Indonesia. Populasi teripang yang terancam di alam mendorong teripang harus diproduksi melalui pembenihan dan pendederan. Melalui pendederan diharapakan anakan teripang lebih kuat dan dapat bertahan hidup lebih baik ketika ditebar pada wadah pembesaran atau direstoking. Penelitian ini bertujuan memberikan informasi teknik pendederan teripang pasir yang lebih baik dan berkarakteristik daerah setempat guna menopang kegiatan pembenihan. Penelitian ini dilaksanakan pada bulan Mei – Juli 2018 di Hatchery CV Pesona Manir Rat, Kabupaten Maluku Tenggara. Juvenil teripang pasir berusia 30 – 36 hari, dipelihara pada hapa berukuran 100 x 100 x 70 cm dengan kepadatan 200 individu / hapa. Pada satu bak pemeliharaan ditempatkan satu buah hapa. Selama pemeliharaan dilakukan pergantian air sebanyak 100 – 150 % dan diberikan satu liter Navicular sp. setiap hari. Aerasi dipasang sebanyak 4 titik pada setiap hapa dan dilakukan pengukuran kualitas air setiap hari. Diakhir penelitian, dilakukan pengukuran panjang tubuh dan perhitungan mortalitas. Hasilnya juvenile teripang yang dipelihara mengalami pertumbuhan mutlak berkisar antara 1,98 – 2,1 cm dengan rata-rata pertumbuhan mutlak sebesar 2,03 cm. Mortalitas rata-rata yang diperoleh sebesar 53, 83 % dengan kisaran 53 % - 55 %. Berdasarkan pembahasan disimpulkan bahwa teknik ini dapat diterapkan dalam pendederan teripang pasir.

Abstract

AbstractSea cucumber Holothuria sp. is a marine biota that has economic value. The rearing activity of sea cucumbers is still limited to the have bay or strait areas with relatively calm coastal. This research aimed to determine the effectiveness of two types of pen‒culture system for sea cucumber rearing to the influence of ocean waves and currents. This research was done from February to July 2017 in the coastal of Rat village, Southeast Maluku Regency. The two of cultivated containers tested were a conventional pen‒culture (treatment A) and engineered pen‒culture (treatment B). A total of 30 individuals sea cucumber seeds sized 4‒6 cm were released at each pen‒culture. Survival rate and water quality were also calculated as supporting data. Observation of endurance and clearance of pen‒culture was done every two weeks. The result of visual observation showed that conventional pen‒culture treatment A was more quickly damaged and it was more damaged compared to engineered pen-culture treatment B.Through t‒test we got T count (1.065) < Ttable (6.313) for survival and T count (0.084) < Ttable (1.782) for growth. The result means that treatment A and treatment B have the same effect onsurvival rate and growth of sea cucumber. The results showed that treatment B was better applied to more open waters than treatment A. Keyword: endurance, pen‒culture, sea cucumber, survival, growth  AbstrakTeripang Holothuria sp. merupakan biota laut yang memiliki nilai ekonomis. Kegiatan budidaya teripang masih terbatas pada daerah‒daerah yang berteluk atau berselat dengan perairan yang relatif tenang. Penelitian ini bertujuan untuk membandingkan efektivitas dua sistem budidaya teripang dalam kurungan tancap terhadap pengaruh gelombang laut dan arus. Penelitian ini berlangsung dari bulan Februari hingga Juni 2017 di perairan Desa Rat, Kabupaten Maluku Tenggara. Dua tipe wadah budidaya yang diujicobakan adalah kurungan tancap konvensional (perlakuan A) dan kurungan tancap yang direkayasa (perlakuan B). Pada setiap kurungan tancap, dimasukkan teripang pasir berukuran 4‒6 cm sebanyak 30 ekor. Sebagai data pendukung, dihitung persentase kelangsungan hidup dan pengukuran kualitas air. Pengamatan ketahanan dan kebersihan kurungan tancap dilakukan setiap dua minggu sekali. Hasil pengamatan visual diketahui bahwa kurungan tancap perlakuan A lebih cepat rusak dan mengalami kerusakan yang lebih besar dibandingkan perlakuan B. Melalui uji-tdiperoleh hasil Thitung (1,065) < Ttabel (6,313) untuk kelangsungan hidup, dan Thitung (0,084) < T tabel (1,782) untuk pertumbuhan.  Hasil uji‒t bermakna bahwa perlakuan A dan perlakuan B memiliki pengaruh yang sama terhadap kelangsungan hidup dan pertumbuhan teripang. Hasil pengamatan menunjukkan bahwa perlakuan B lebih baik diaplikasikan pada perairan yang lebih terbuka dibandingkan perlakuan A. Kata kunci: ketahanan, kurungan tancap, teripang, kelangsungan hidup, pertumbuhan
