Abstract

Abstract. The Banggai cardinalfish Pterapogon kauderni is a species of national and international conservation concern. Established in November 2019, the Banggai marine protected area (MPA) in Central Sulawesi, Indonesia covers most of the endemic range of this ornamental fish. The third repeat survey (T2 monitoring) under the National Action Plan for Banggai Cardinalfish Conservation (NAP-BCFC) was carried out in October 2019 at eight sites in the Bokan Kepulauan region within the MPA. The T2 monitoring used the standard NAP-BCFC belt transect method. Data were collected on P. kauderni abundance (by size class: recruits, juveniles, adults) and microhabitat (sea urchins, sea anemones, hard corals, and others). Data were evaluated with respect to the T0 (2017) survey and T1 (2018) monitoring at the same sites, as well as previous surveys in 2004 (2 sites) and 2012 (4 sites). The data show wide between-site variation in P. kauderni and microhabitat parameters, with one subpopulation at very high risk of extirpation. Trends included declines over time in P. kauderni, sea urchin and sea anemone abundance, with an increase since 2017 in hard coral microhabitat use by adult P. kauderni. We recommend evaluation of other P. kauderni populations in Bokan Kepulauan and specific site or zone-based actions. However, we conclude that the most urgent priority for P. kauderni conservation in Bokan Kepulauan is protection of key microhabitat through a moratorium on sea urchin and sea anemone collection in P. kauderni habitat.  Keywords: Banggai cardinalfish, endangered species, marine conservation, microhabitat, monitoring, ornamental fishery, CITES

Abstract

The objectives of present study were to determine the distribution of sediment associated with shoreline changes and to analyze the beach dynamics in Rening Beach. Sediment samples were taken from seventeen sampling points spread along the beach, and then followed by the lab test using granulometri method to determine the characteristics of sediment. Shoreline change was analyzed using analysis of satellite imagery in 2011, 2014 and 2016, while the sediment transport were analyzed using Hjulstrom graph. Then, Rening Beach dynamics can be analyzed. Sediment test results showed that sediment type in Rening Beach was dominated by sand with diameter of between 0.25-5 mm. The ocean currents movement was dominantly to the west. The results of shoreline change analysis between the years 2011-2016, and Hjulstrom graph analysis showed the same pattern that Rening Beach was eroded. The Rening Beach was high dynamics with subjected to beach erosion in the form of littoral drift due to longshore currents.Penelitian ini bertujuan untuk mengetahui perubahan garis pantai, transpor sedimen dan dinamika pantai di Pantai Rening. Pengambilan data arus dan sampel sedimen diambil dari tujuh belas titik pengambilan sampel yang tersebar merata di sepanjang perairan Pantai Rening. Sampel sedimen kemudian diujikan di laboratorium menggunakan metode granulometri untuk mengetahui karakteristik sedimen. Perubahan garis pantai dianalisa menggunakan analisis peta citra satelit tahun 2011, 2014 dan 2016, sedangkan pola transpor sedimen dianalisa menggunakan grafik Hjulstrom. Dari hasil analisa perubahan garis pantai dan transpor sedimen, dapat dianalisa dinamika Pantai Rening. Hasil uji sedimen menunjukkan bahwa jenis sedimen didominasi oleh pasir sedang dengan diameter antara 0.25-5 mm. Pergerakan arus dominan mengarah ke arah barat. Hasil analisis perubahan garis pantai antara tahun 2011-2016, dan analisa grafik Hjulstrom menunjukkan pola yang sama bahwa pada Pantai Rening mengalami erosi dan mundurnya garis pantai. Dinamika Pantai Rening cukup tinggi dengan kecenderungan terjadi erosi pantai berupa littoral drift akibat arus sejajar pantai.

Abstract

Barramundi Lates calcarifer is a high economic value fish in Indonesia and Southeast Asia countries. However, the aquaculture system still experiences problems, including the high cost of production, specifically from feed, which is due to its relatively slow growth and low digestibility. Therefore, this study aims to determine alternative ingredients that can be used in the fish diet to improve feed utilization and growth performance using pumpkin flour Cucurbita moschata. A completely randomized design (CRD) with 6 treatments and 3 replications was adopted in this study. The tested diet was (A) diet without pumpkin flour (control), (B) with 5% (C) 10% (D) 15% (E) 20%, and (F) 25%. The size of the Barramundi samples was 3-4 cm on average and the body weight was 1-3 g at the stocking density of 15 fish/container. The fish fed as much as 10% body weight daily, which is divided into 2 times, namely 08.00 AM and 4.00 PM for 60 days. The results showed that the addition of pumpkin flour had a significant effect on weight gain, daily and specific growth rate, survival, feed efficiency, conversion ratio, and carcass protein (P0.05). The diet with 5% pumpkin flour gave the best results over other treatments, with an average weight gain of 0.761 g, feed conversion of 1.578, feed efficiency of 63.455%, and a daily and specific growth rate of 0.012 g and 0.738%, respectively, The highest carcass protein content was found in the control treatment with a value of 18.210%, which was not significantly different from the 5% pumpkin flour treatment. Therefore, it is concluded that pumpkin flour can be added to the Barramundi diet as much as 5%. Keywords: Barramundi, Snapper, pumpkin, feed utilization

Abstract

The shipyard industry plays an important role in supporting fishing activities and efforts to fulfill animal protein for humans. It is an industry that has an orientation to produce a product in the form of a ship. There are two types of shipyards, which are offshore buildings and floating buildings - both are used to build new ships and repair old ships. Based on the level of technology used by the shipyard industry, it is divided into modern, traditional, and semi-modern shipyards. Its productivity can see the advantages and disadvantages of a shipyard to ensure this industry remains to exist. Several factors need to be taken into account to increase the shipyard productivity, including land or location, human resources, technology, and materials.Keywords:ProductivityShipyardTechnology
