Abstract

Rumput laut jenis Eucheuma cottonii adalah salah satu hasil perikanan yang mempunyai nilai ekonomis cukup penting karena mengandung karagenan yang merupakan bahan dasar dalam industri farmasi, makanan, maupun bahan industri lain. Mengingat besarnya permintaan pasar akan kebutuhan rumput laut maka perlu dilakukan usaha untuk meningkatkan produksinya. Namun seiring dengan meningkatnya permintaan, pembudidaya sering mengalami permasalahan antara lain bibit rumput laut yang dihasilkan belum maskimal baik dari segi jumlah maupun kualitas, sehingga perlu ada kajian untuk menghasilkan pertumbuhan benih bibit rumput laut yang baik yaitu menggunakan pupuk Conway pada media kultur rumput laut dari hasil kultur jaringan. Pupuk conway mengandung unsur nutrien yang sangat bermanfaat bagi pertumbuhan rumput laut. Penelitian ini bertujuan untuk mendapatkan dosis pupuk Conway yang tepat pada media kultur terhadap pertumbuhan bibit rumput laut E. cottonii. Penelitian ini menggunakan E.cottoni dari hasil kultur jaringan Seameo Biotrop. Penelitian ini menggunakan Rancangan Acak Lengkap dengan 5 perlakuan dan 5 ulangan yaitu dosis pupuk Conway (0, 2, 4, 6, dan 8 ml). Padat tebar E.cottoni yaitu 5 eksplan per wadah. Hasil penelitian didapatkan bahwa pemberian pupuk Conway dengan dosis berbeda berpengaruh sangat nyata (P<0.01) terhadap pertumbuhan panjang mutlak dan laju pertumbuhan spesifik, serta pertumbuhan bobot mutlak E. cottonii, dengan nilai tertinggi yaitu masing-masing 1,04 cm, 0,014%, dan 0,25 g pada perlakuan dosis pupuk Conway 8 ml. Seaweed Eucheuma cottonii is one of the fishery products that have highly important economic value because it contains carrageenan which is a basic ingredient in pharmaceuticals, food, and other industrial materials. Given the large market demand for seaweed, it is necessary to make efforts to increase production. However, along with increasing demand, cultivators often experience problems, the constraints that are often experienced are, among others, the seaweed seeds produced are not optimal both in terms of quantity and quality,  so there needs to be a study to produce good seaweed seed growth, namely using Conway fertilizer on seaweed culture media from tissue culture results. Conway fertilizer contains nutrients that are very beneficial for the growth of seaweed. This study aims to obtain the correct dosage of Conway fertilizer in culture media on the growth of E. cottonii seaweed seedlings. This study used E.cottoni from the Seameo Biotrop tissue culture.

The results showed that the application of Conway fertilizer with different doses had a very significant effect (P<0.01) on absolute length growth, specific growth rate, and absolute weight growth of E. cottonii, with the highest values of 1.04 cm, 0.014%, and 0,25 g, respectively, at the Conway fertilizer dose of 8 mL. 
康威肥料在培养媒介中对海藻生长的Eucheuma cottonii种子的使用
棉花型欧几里得海藻是最具经济价值的食品之一,因为它含有氢气,而氢气是制药、食品或其他行业的基本成分。鉴于市场上对海藻的巨大需求,必须努力增加产量。但随着需求的增加,传粉者经常会遇到问题,包括产生的海藻在数量或质量上都不是阳性的,因此有必要进行研究,以产生生长良好的海藻种子,即在网络培养的海藻培养基中使用康威豆。这些球道含有对海藻生长非常有用的营养物质。本研究的目的是在培养基上获得合适剂量的康威肥料,以对抗棉花苔的生长。本研究使用了来自Seameo Biotrop网络文化的E.cottoni。本研究采用患者计划,共有5次治疗和5次重复剂量的康威颗粒(0、2、4、6和8ml)。E.cotton的厚度为每只容器5个表达式。研究结果发现,不同剂量的康威肥料对棉花的绝对长生长和比生长率以及棉粪绝对棉的生长都有非常真实的影响(P<0.01),每种都有1.04cm、0.014%的较高值,海藻棉胶是一种具有高度重要经济价值的渔业产品,因为它含有卡拉胶,卡拉胶是制药、食品和其他工业材料的基本成分。鉴于市场对海藻的需求很大,有必要努力增加产量。然而,随着需求的增加,栽培者经常遇到问题,经常遇到的限制因素包括,生产的海藻种子在数量和质量方面都不是最佳的,因此需要进行一项研究,以产生良好的海藻种子生长,即从组织培养结果中在海藻培养基上使用康威肥料。康威肥料含有对海藻生长非常有益的营养物质。本研究旨在获得培养基中康威肥料对棉花海藻幼苗生长的正确剂量。本研究使用了来自Seameo Biotrop组织培养的E.cottoni。它采用了一个完全随机的设计,有5个处理和5个重复,即康威肥料的剂量(0、2、4、6和8ml)。棉花E.cottoni的放养密度为每个容器5个外植体。结果表明,施用不同剂量的康威肥料对棉花的绝对长度生长、比生长率和绝对重量生长有非常显著的影响(P<0.01),在康威肥料用量为8mL时,其最高值分别为1.04cm、0.014%和0.25g。

期刊介绍: The Journal of Marine Research publishes peer-reviewed research articles covering a broad array of topics in physical, biological and chemical oceanography. Articles that deal with processes, as well as those that report significant observations, are welcome. In the area of biology, studies involving coupling between ecological and physical processes are preferred over those that report systematics. Authors benefit from thorough reviews of their manuscripts, where an attempt is made to maximize clarity. The time between submission and publication is kept to a minimum; there is no page charge.
