  • Application of Probiotic and Fermented Feed in the Nursery of Anguilla
           bicolor

    • Authors: Agoes Soeprijanto, Guntur Guntur, Muhammad Fakhri
      Abstract: The main problem in Anguilla bicolor nursery is low productivity and survival rate (SR) that caused by poor water quality and low digestibility of feed. The purpose of this study was to evaluate the application of probiotic and fermented feed on A. bicolor nursery from stadia elver to fingerling. In this study, one treatment of probiotic and fermented feed and one control without supplementation of probiotic and fermented feed were applied. Probiotic of 5 ml/m3 for every three days and fermented feed with protein of 42% were administered for 4 months. The results showed that survival rate of 93% and specific growth rate of 2.82%/day were obtained in the treatment of probiotic and fermented feed while survival rate of 81% and specific growth rate of 2.76% were produced in control tank. Feed conversion ratio and total production in treatment tank were 1.8 and 18.01 kg, respectively. On the other hand, feed conversion ratio and total production in control tank were 2.3 and 14.68 kg, respectively It can be concluded that probiotic and fermented feed application were able to improve the productivity of A. bicolor.

  • Determination of Optimal Planting Distance Between Seed Clump on Seaweed
           Verticulture Method

    • Authors: Petrus R Pong-Masak, Nelly H Sarira
      Abstract: Seaweed Kappaphycus alvarezii cultivation with the verticulture method has been introduced by LP2BRL since 2013 until now. However, scientific studies on other technical aspects are needed to improve the quality, quantity, and continuity of production and utilization of land in a maximum and productive manner. One of them is the difference of planting distance between seed clump of seaweed. The purpose of this study is to determine the optimal planting distance between seed clump on seaweed verticulture method. Cultivation construction using a 10x10 m2 buoyancy raft containing 36 vertical nets measuring 5x2 m2/net. Each net is made into a knot as a ring rope is tied back and forth or two sides. Seaweed seeds with an initial weight of 50 g were tied to a vertical net with a distance between knot on the verticulture net of 15 cm, 25 cm, and 35 cm. Seaweed cultivation is done for 3 cycles (1 cycle = 45 days) and done continuously in the cycle of planting season. The experimental units were prepared with Completely Randomized Design (RAL) with 3 replications. The results showed that daily growth rate (DGR) and carrageen content of seaweed planted with a distance of 15 cm, 25 cm, and 35 cm between clumps were not significantly different (P>0,05). However, it is recommended to apply 25 cm distance between seed clump for the optimization of production in the verticulture method.

  • Diet and Feeding Habits of the Javelin Grunt Pomadasys kaakan (Cuvier,
           1830) in Pabean Bay West Java

    • Authors: Chilmia Ayu Annisa, M Fadjar Raharjo, Ahmad Zahid, Charles P.H Simanjuntak, Aries Asriansyah, Reiza M Aditriawan
      Abstract: Pabean Bay is an estuary area that has the potential fisheries resources. One of which is the javelin grunt. A study was conducted to identify food item and explain diet of habit the javelin grunt Pomadasys kaakan (Cuvier & Valenciennes, 1830) in Pabean Bay, West Java, from July until December 2016 on each month. Fish samples were collected by gill net and trap net. Analysis the food used the method the index of relative importance, niche breadth, niche overlap, and feeding strategy. The result showed that the juvelin grunt is a carnivore, however more precisely it is crustacivore. Food composition could be divided into nine groups were Acetes sp., Penaeus sp., Portunus sp., Clupeidae, Ambassidae, Sciaenidae, Gobiidae, Sillaginidae, and organisms unidentified. The main food is type Penaeus sp. same according to time and size every month. The main food did not change but the proportion it was be changed as getting the measure of the length, the proportion it was type Penaeus sp. on the size 41-84 mm (96.17), 85-130 mm (95.64), and 131-175 mm (88.15).

  • Wind-Driven Coastal Upwelling in the Southern Coast of Yogyakarta

    • Authors: Faizal Rachman, Ratih Ida Adharini, Riza Yuliratno Setiawan, Indun Dewi Puspita, Endy Triyannanto
      Abstract: Satellite measurement provides synoptic view of sea surface wind and can be used to study variability of coastal upwelling. Here we analyzed data of 12 years of satellite-derived sea surface wind, sea surface temperature (SST), and sea surface chlorophyll-a (Chl-a) to examine the spatial and temporal distributions of coastal upwelling off the Yogyakarta waters. Results show that upwelling occurs during the Southeast Monsoon (SEM) season. During this season, the Yogyakarta waters are dominated by strong wind speed (~7 m/s) and SST cooling (25 °C). Whereas during the Northwest Monsoon (NWM) season the low wind speed (<4 m/s) no longer favor upwelling and SST cooling. We suggest that as the Yogyakarta coastline is oriented east-west, northwesterly winds result in downwelling condition at the coast, while southeasterly winds lead to the offshore Ekman transport of surface water and subsequent upwelling.

  • Restoration of Mangrove Ecosystem in Coastal Village Based on
           Co-Management

    • Authors: Rudianto Rudianto
      Pages: 1 - 12
      Abstract: The purpose of the research was to reorder the mangrove ecosystem restoration of coastal villages in order to overcome the damage coastal environments that have been damaged as a result of changes in land use. Data collection was done by using questionnaires and interviews with stakeholders. The study was conducted for three years from 2013 until 2016 with locations in Gresik and Malang districts. Data analysis was done by Partial Least Square and Analytical Hierarchy Process method to find out the priority order of restoration of the coastal ecosystem. In addition to SWOT analysis was conducted to determine the institutional capacity of the village and which would be responsible for restoring coastal ecosystems. The results show that the order of handling on coastal ecosystem damage was firstly mangrove forest, secondly coral reef, thirdly estuary area and fourthly seagrass area. Institutions responsible for handling the level of damage to coastal ecosystems was a village government, which was supported by the regional work units (SKPD) at the district level. Besides that, the role of government, private and community became the key to success on the successful implementation of restoration. Technical manual implementation of Coastal Ecosystem restoration-based co-management was necessary for the restoration of coastal ecosystems.
