Abstract. Mayalibit Bay has an unique topography due to it has only one way long canal , narrow, and devious that connecting to open sea. Study on the water mass dynamics concerning to elevation and tidal current in Mayalibit Bay was conducted by constructing the 2D numerical hydrodynamics model which was simulated for 30 days to describe the pattern of elevation and water current which was resulted from tidal processes. The 2D hydrodynamic equation was employed by finite difference methods. Validation result showed that the model has a good performance and it was relevance to in-situ measurement. The pattern of elevation and water current from many tide periods had been spatially analyzed. Generally, simulation showed that there was a significant difference between the elevation and water currents pattern inside and outside the bay during high and low tides.. Elevation and water current have higher value during highg tide (maximum 0.35 m and 0.2 m/s) than low tide period (maximum 0.14 m and 0.1 m/s ) with the velocity of water current was faster at ebb-tide or low tide. The water current in entry canal has higher value than in any part of the bay which themaximum velocity was varied from 1.6 m/s (flood-tide) to 3.7 m/s (ebb-tide). The direction of current during high tide flows was dominantly to the West-Northwest or enters the bay by following its geometric and to the East-Southeast or exits from the bay during the ebb-tidesKeywords :  Tidal; quasi-enclosed waters; numerical models; finite difference  Abstrak. Teluk memiliki topografi yang unik karena hanya memiliki satu celah atau jalur panjang, sempit, dan berkelok yang menghubungkannya dengan laut terbuka. Kajian dinamika massa air terkait elevasi dan arus pasang surut di Teluk Mayalibit telah dilakukan dengan membangun sebuah model numerik hidrodinamika 2D yang disimulasi selama 30 hari untuk menggambarkan pola elevasi dan arus akibat pasang surut. Persamaan hidrodinamika 2D diselesaikan dengan metode beda hingga. Hasil validasi menunjukkan bahwa model telah memiliki performa yang cukup baik dan relevan bila diverifikasi dengan hasil pengukuran di lapangan. Pola elevasi dan arus dalam beberapa periode pasang surut dianalisis secara spasial. Hasil simulasi menunjukkan bahwa ada perbedaan yang signifikan antara elevasi dan pola arus di dalam dan di luar teluk selama periode pasang purnama dan pasang perbani. Elevasi dan arus memiliki nilai yang lebih tinggi pada saat pasang purnama (maksimum 0,35 m dan 0,2 m/detik) dibandingkan dengan pada saat pasang perbani (maksimum 0,14 m dan 0,1 m/detik) dengan kecepatan arus yang lebih tinggi pada saat surut. Arus di jalur masuk teluk memiliki nilai yang lebih tinggi dibandingkan bagian manapun di dalam teluk, dimana kecepatan maksimumnya bisa mencapai 1,6 m/detik (pasang) sampai 3,7 m/detik (surut). Arah arus dominan di dalam teluk pada saat pasang adalah Barat - Barat Daya atau masuk ke dalam teluk mengikuti geometrinya dan ke Timur-Tenggara atau ke luar teluk pada saat surut.

Abstract

Karangantu Nusantara Fishing Port (NFP) accommodates production, processing and marketing activities, also fishermen development. Services for vessels as production facilities include: providing a home base for the fishing fleet, ensuring smooth loading of captured fishes, providing supplies for vessels such as fresh water, fuel, ice and others. This study aims to analyze the activities and operational performance and find out the determinants of the performance of Karangantu NFP. This research was conducted in October 2019 to January 2020 at the Karangantu NFP. Data analysis was performed using two methods; the first is a descriptive method to analyze the operational activities of the Karangantu NFP and assess operational performance based on the Decree of Director General of Capture Fisheries in 2015 Number 20 / KEP-DJPT / 2015; the second is Structural Equation Model (SEM) method, which is to define the determinants of Karangantu NFP performance. The results showed that Karangantu NFP operational activities continued to increase. Ship visits during 2019 increased by 15.75%. The production volume of landed fish increased by 9.0%, but the value of production fell by 7.1% due to the catches of most fish with low economic value and poor fish quality. The performance evaluation of 27 criterias based on the Decree of Director General of Capture Fisheries in 2015 showed that the operational performance of the Karangantu NFP during October 2019-January 2020 performed well. Based on SEM test results, internal (human resource/personal, budget, fishermen, and productivity) variables have the most influence on NFP performance. Keywords: Performance, SEM, Fishing Port, Capture Fisheries, KarangantuABSTRAKPelabuhan Perikanan Nusantara (PPN) Karangantu menampung aktivitas produksi, pengolahan dan pemasaran, serta pembinaan nelayan.

Abstract

Diopatra species are members of the family Onuphidae (Polychaeta, Annelida) that are widely used as fishing bait. These tubicolous worms are common in particular mangrove areas of Cilacap. However, biological aspects of Diopatra sp. inhabiting the areas have not been studied. In the present work, we investigated several biological aspects of the worms, including the segment number, the body weight and the sex ratio, based on Diopatra samples collected from four mangrove habitats of Jeruklegi Village, Cilacap Regency, between June and July 2021. The results show that the average numbers of segments of Diopatra sp. obtained ranged from 195 to 216 segments, whereas the average body weights ranged from 2.03 to 3.12 g, and the average sex ratios ranged from 0.5 to 1.3. In general, the biological aspects of Diopatra sp. between sampling sites were relatively similar; this can be attributed to the similar environmental conditions at all sampling sites, including salinity (25–32 ppt), water temperature (30–32 oC), dissolved oxygen (6.4–8.8 ppm) and pH (7). While Diopatra worm farming is necessary so that local people do not rely on natural catch, a further taxonomic study is required to reveal the identity of this economically important local species.Keywords:Biological aspectDiopatraMangrove habitatPolychaetesTubicolous worms

Abstract. The objective of the present study was to evaluate the possibility of jaloh leaf powders as alternative raw material for the formulated diet ofAfrican catfish (Clarias gariepinus). Four concentrations of jaloh leaf powders (0%, 5%, 10% and 15%) were examined in this study. The experimental fish were fed three times a day (on 08.00 am, 12.00 am and 17.00 pm) with feeding ration of 5% of body weight and the fish was reared for 35 days. The ANOVA test showed that the different concentration of jaloh leaf powders gave a significantly effect on growth performance of African catfish larvae (P0,05) but did not give significantly effect on the survival rate (P0,05). The Duncans test showed that the higher survival rate and growth performance were found in the control (without jaloh leaf powders). Therefore it is concluded that the jaloh leaf powders is not suitable as alternativerows material for African catfish diet.Key words: Protein; Carbohydrate; Catfish; Alternative feed Abstrak. Penelitian ini bertujuan untuk mengevaluasi kemungkinan pemanfaatan  tepung daun jaloh (S. tetrasperma) sebagai bahan baku alternatif untuk pakan ikan lele(C. gariepinus). Dalam penelitian ini telah diuji beberapa tingkat proporsi tepung daun jaloh yaitu (0%, 5%, 10%, dan 15%) .Pemberian pakan dilakukan tiga kali sehari, yaitu pada pukul 08.00, 12.00 dan 17.00 WIB,sebanyak5%dari berat bobot tubuhnyaselama 35 hari. Hasil uji ANOVA menunjukkan bahwa pemberian tepung daun jaloh memberikan pengaruh nyata (P0,05) terhadap pertumbuhan mutlak dan pertumbuhan harian benih ikan lele dumbo (P0,05), namun tidak berpengaruh nyata terhadap kelangsungan hidup (P0,05). Uji lanjut Duncan’s  menunjukkan bahwa perlakuan kontrol (tanpa daun jaloh) dalam pakan memberikan hasil terbaik dari segi pertumbuhan mutlak, pertumbuhan harian dan kelangsungan hidup. Oleh karena itu dapat disimpulkan tepung daun jaloh kurang sesuai sebagai bahan baku alternatif dalam pakan ikan lele dumbo.Kata kunci: Protein; Karbohidrat; Ikan lele; Pakan alternatif
