Abstract

Kementerian Kelautan dan Perikanan (KKP) menargetkan produksi rumput laut pada tahun 2015 sebesar 10,3 juta ton. Salah satu jenis rumput yang sangat potensial untuk dikembangkan yaitu Caulerpa lentillifera. Rumput laut ini banyak digemari masyarakat dalam negeri maupun luar negeri karena memiliki nilai ekonomis yang sangat penting yaitu sebagai bahan makanan segar dan bahan untuk obat-obatan. Namun produksi C. lentillifera sendiri belum dapat tercukupi karena bersifat musiman dan masih banyak mengandalkan hasil dari alam. Oleh karena itu perlu adanya upaya untuk meningkatkan produksi C. lentillifera dengan  cara budidaya. Salah satu faktor yang mempengaruhi pertumbuhan  C. lentillifera dalam budidaya adalah ketersediaan nutrien yang biasanya dapat diperoleh dari pemberian pupuk. Berdasarkan hal tersebut, maka dilakukan penelitian pengaruh perendaman pupuk organik cair dengan dosis yang berbeda dan dosis yang terbaik terhadap pertumbuhan C. lentillifera. Peneltian ini menggunakan metode eksperimen dengan rancangan acak lengkap (RAL) terdiri dari 4 perlakuan dan 5 kali ulangan. Adapun perlakuan tersebut yaitu perlakuan A (0 mL), B (1,5 mL), C (2,5 mL) dan D (3,5 mL) dengan lama perendaman 6 jam. Data yang didapatkan selama penelitian yaitu laju pertumbuhan spesifik (SGR) dan kualitas air. Data dianalis dengan Anova dan dilakukan uji lanjut Duncan. Hasil penelitian menunjukkan perendaman pupuk organik cair dengan dosis yang berbeda berpengaruh sangat nyata terhadap laju pertumbuhan spesifik C. lentillifera. Perlakuan D (perendaman dosis 3,5 mL) memberikan hasil terbaik dari semua perlakuan dengan laju pertumbuhan spesifik sebesar 3.29±0.06%/hari. Ministry of Maritime Affairs and Fisheries (KKP) targets 10,3 million tons seaweed production in 2015. One of potential seaweed to be developed is Caulerpa lentillifera. This type of seaweed is preferred by many people in Indonesia and the world because it has high economic value as fresh produce and for medicine. However, production is still insufficient because it is seasonal variety and its production still depends on natural harvest. Therefore, it is needed to increase C. lentillifera production by cultivation. One factor that affects C. lentillifera growth in the cultivation is the availability of nutrient. Therefore, a study on difficult dosage of liquid fertilizer throught immertion method is needed. The aim of this research was to determine the effect of different dosage of liquid fertilizer on the growth of C. lentillifera and to find out the proper dosage which can produce the best growth of C. lentillifera. This study was done experimentally with Completely Randomised Design. There were 4 treatments: A (0 mL), B (1,5 mL), C (2,5 mL) and D (3,5 mL) with time of immersion of 6 hours. Each treatment was replicated 5 times. The data collected were specific growth rate (SGR) and water quality parameter. Data was analyzed using collected were Anova and followed by Duncan’s test. The result shows that different dosage of liquid organic fertilizer showed highly significantly effected the specific growth rate (SGR). Treatment D (dose of 3,5 mL) gives the best result compared with another treatments, with specific growth rate of 3.29±0.06%/day.

D. brachyurum merupakan salah satu pakan alami yang pergerakannya lambat dan berenang bebas dalam kolom air, serta mempunyai nilai kandungan nutrisi yang tinggi. Kultur D. brachyurum memerlukan pengkajian diet mikroalga untuk mendapatkan performa pertumbuhan terbaik. Tujuan penelitian ini adalah mengetahui pengaruh diet mikroalga yang berbeda terhadap performa pertumbuhan (kepadatan populasi, laju pertumbuhan dan produksi telur) D. brachyurum dan mendapatkan diet mikroalga yang memberikan hasil performa pertumbuhan (kepadatan populasi, laju pertumbuhan dan produksi telur) D. brachyurum terbaik. Metode penelitian menggunakan RAL dengan 4 perlakuan 4 ulangan yang kepadatannya 1 ind/ml. Diet yang digunakan untuk kultur D. brachyurum adalah Chlorella vulgaris; Chaetoceros calcitrans; Nannochloropsis oculata; dan Tetraselmis chuii. Hasil penelitian menunjukkan bahwa pemberian diet mikroalga yang berbeda berpengaruh nyata (P<0,05) pada performa pertumbuhan D. brachyurum. Diet T. chuii menghasilkan kepadatan terbaik pada anakan (neonata) (3,013±1,582 ind/ml), juvenil (2,513±0,638 ind/ml), dewasa (7,325±1,981 ind/ml), dewasa bertelur (4,050±2,401 ind/ml) dan dewasa beranak (8,975±1,569 ind/ml). Kepadatan total juga pada diet T. chuii (25,875±1,142 ind/ml) yang merupakan nilai tertinggi. Diet T. chuii juga menunjukkan hasil terbaik dan berbeda nyata (P<0,05) dibanding perlakuan lain pada laju pertumbuhan (0,163±0,002 /hari). Diet N. oculata menunjukkan hasil terbaik serta berbeda nyata (P<0,05) pada produksi telur (3,446±0,363 telur/ind), namun tidak berbeda nyata terhadap Chaetoceros calcitans (3,104±0,705 telur/ind). The live food organisme in aquaculture is very important for larvae rearing. D. brachyurum is one of the live food organisme  which slow movement and has capabiity as a free swimmer in water column, and has a high nutritional value. The study of D. brachyurum fed by different microalgal diets needs to be conducted in order to perceive its growth performance. This study aimed to determine the effect of different microalgal diets on growth performance (population density, growth rate and egg production) of D. brachyurum and suitable microalgal that supperied growth performance (population density, growth rate and egg production) of D. brachyurum. The method of this study was experimental laboratory which used completely random design (CRD) with 4 treatment and 4 replicates. The initial density of D. brachyurum was 1 ind/ml. The diets that used in this study here Chlorella vulgaris; Chaetoceros calcitrans; Nannochloropsis oculata; and Tetraselmis chuii. The results of this study showed that different microalgal diets had significant effect (P<0,05) on growth performance of D. brachyurum. The highest density of the neonata (3.013±1.582 ind/ml), juvenile (2,513±0.638 ind/ml), adult (7,325±1,981 ind/ml), adult spawn (4,050±2,401 ind/ml) and adult childbearing (8,975±1,569 ind/ml) was on D treatment (fed by T. Chuii). The highest total density of D. brachyurum (25.875±1.142 ind/ml) was on D treatment (fed by T. Chuii). D. brachyurum that fed by T.chuii had best growth rate value (0.163±0.002/day) significantly different (P<0.05) than other treatments. D. brachyurum that fed by N. oculata had best egg production value (3.446±0.363 eggs/ind) significantly different (P<0.05), but not significantly different with egg production value of D. brachyurum that fed by C. calcitrans (3.104±0.705 eggs/ind).

Abstract

Oithona sp. merupakan salah satu jenis copepoda yang memungkinkan untuk dikembangkan sebagai substitusi pakan pengganti Artemia. Oithona sp. juga mempunyai  kandungan nutrisi yang lebih baik dari Artemia. Penelitian ini telah dilakukan dengan tujuan untuk mengetahui pengaruh pemberian kombinasi pakan alami sel fitoplankton dan bahan organik (bekatul, ampas tahu, tepung ikan) yang difermentasi terhadap performa pertumbuhan Oithona sp., selain itu juga untuk mengetahui dosis kombinasi pakan alami sel fitoplankton dan bahan organik (bekatul, ampas tahu, tepung ikan) yang difermentasi yang memberikan performa pertumbuhan Oithona sp. terbaik.Metode yang digunakan selama penelitian Rancangan Acak Lengkap (RAL) dengan 5  perlakuan 3 kali ulangan. Kultur Oithona sp. dilakukan di botol kaca dengan volume 10 mL dan kepadatan awal Oithona sp. 1 ind/mL. Pemeliharaan dilakukan selama 21 hari. Perlakuan dalam penelitian ini yaitu A (100% fitoplankton : 0% fermentasi), B (75% fitoplankton : 25% fermentasi), C (50% fitoplankton : 50% fermentasi), D (25% fitoplankton : 75% fermentasi), E (0% fitoplankton: 100% fermentasi). Pakan Alami sel fitoplankton yang digunakan yaitu Chaetoceros calcitrans dan Isochrysis galbana, sedangkan bahan organik yang digunakan yaitu bekatul ampas tahu dan tepung ikan dengan perbandingan 35%: 35%: 30%.Hasil penelitian menunjukkan pemberian kombinasi pakan alami sel fitoplankton dan bahan organik yang difermentasi berpengaruh nyata (P<0,05) terhadap performa pertumbuhan Oithona sp. Pemberian  fitoplankton 50% dan fermentasi 50% merupakan dosis terbaik dalam penelitian ini. Kepadatan puncak Oithona sp. dengan pemberian fitoplankton 50% dan fermentasi 50% mencapai 14,333 ± 0,115 ind/ml, sedangkan kepadatan naupli dengan pemberian fitoplankton 50% dan fermentasi 50% mencapai 6,930 ± 0,360 ind/ml, kepadatan copepodit 7,470 ± 0,321 ind/ml, kepadatan dewasa 8,970 ± 0,500 ind/ml. Oithona sp. is one of copepods that possibly can be developed as substitution food replacement for Artemia. This study was done with the aims to determined the effect of combination of live food organisms of fitoplankton cells and fermented organic matters on the growth performances of Oithona sp., moreover to determine the dosage of fitoplankton cells and fermented organic matters that gives the good growth  performances of Oithona sp.The method experiment used in this research. There was designed by completely randomized design (CRD) with five treatments and three replicates respectively. Those treatments were A (100% phytoplankton: 0% fermentation), B (75% phytoplankton: 25% fermentation), C (50% phytoplankton: 50% fermentation), D (25% of phytoplankton: 75% fermentation), E (0% phytoplankton: 100% fermentation). The culture was conducted in glass bottle with 10 ml in volume and the initial density of 1 ind/ml. Maintenance was caried out for 21 days. Chaetoceros calcitrans and Isochrysis galbana used as live food in this research. Rice bran, tofu waste and fish meal used as organic matters with a ratio 35% : 35% : 30%. The results showed combination of live food organism of fitoplankton cells and fermented organic matters were significantly effected (P<0.05) on the growth performances of Oithona sp. The treatment of phytoplankton 50% and 50% fermented organic matters was the best dosage that gives the good growth performances of Oithona sp. The highest density reached 14.333 ± 0.115 ind / ml, whereas naupli density, copepodit density, and adult density reached 6.930 ± 0.360 ind / ml, 7.470 ± 0.321 ind / ml, 8.970 ± 0.500 ind / ml respectively.
