  • MODIFIKASI KAPAL PURSE SEINE BERDASARKAN KAJIAN STABILITAS

    • Authors: Hasanudin Hasanudin, Rizky Chandra Ariesta, Totok Yulianto, Ahmad Nasirudin
      Abstract: Based on the results of the investigation of the KNKT, fishing boats still the highest order type of ship that crashed at sea. The relatively small size of fishing vessels and different types of extreme operation when pulling the tool and catches easily lead fishing boat capsized and sank. Some wooden fishing boat 30 GT-owned sea mina recently completed in Batang traditionally experienced heel ± 15 degrees when pulling the net. This paper analyzes the vessel stability for various operating conditions and solutions to steady the ship safe to use. The analysis shows that the stability of existing ships do not meet the criteria Intact Stability IMO, after the addition of the outrigger so ships can meet these criteria.

      Abstract: Fishing boats are used in capturing or collecting aquatic resources. As a means of production, the boat should meet various conditions of seaworthiness i.e. good stability, good seakeeping ability and minimum resistance. Those criteria can be identified when the boat size and the hull form are designed. This study investigates the effect of the boat dimension and the hull form on the stability, resistance and seekeeping ability. Various sizes and hull shapes of a 20 GT fishing boat were simulated, and their performances were compared to the IMO standard. The results suggest that the minimum breadth (B) - draft (d) ratio which meets the stability criterion is 2.50, while the ratio of the center of gravity distance from the keel (KG) and the depth (D) of the boat is 0.65. Furthermore, for the boat with a higher B and D ratio, its resistance is relatively smaller. In terms of seakeeping ability, particularly roll and pitch motions, U type bottom performed better than the Akatsuki bottom. Keywords: fishing vessel, sea keeping, ship hull, stability, resistance

      Abstract: Tanjung Jabung Barat Regency has a great potential for mantis shrimp (Harpiosquilla raphidea) resources. This commodity is highly valued, as its price range from Rp. 143,600 to 180,700 for each individual. Annually, the total catches constitute 125,000-225,000 individuals, which become one of export commodities to various countries. In Tanjung Jabung barat, the mantis shrimp has been caught by using gillnet with mesh size of 10 cm. Unfortunately, mantis shrimp fishing deal with a significant number of bycatch and discards, which potentially have negative impact on sustainable fisheries resources. Therefore, the purposes of this study was to emphasis on sustainable fishing effort of mantis shrimp and identify the composition and proportion of bycatch and discards. A series of surveys was conducted for collecting the amount of species caught by gillnet during mantis shrimp fishing operation. The result shows that the bycatch and discards dominated the total catches making up to 54.99% (7 species) and 22.69% (7 species) respectively. Mean while, the total of fishing catches for mantis shrimp was 22.32%.

      Abstract: A gross tonnage (GT) is a volume capacity of fishing vessel regarding its role in the fisheries resource utilization and management affairs. Information regarding GT is important, hence there is a need to conduct measurement in objective manner. The result of GT recalculation conducted by the Ministry of Transportation on under 30 GT fishing vessels showed that there is a significant difference between the documented GT and recalculated GT which indicates a massive mark down. Consequently, most of owners decline the later result as it goes higher and has impact on operational cost. Regarding that problem, this paper investigates the GT calculation process in Indonesia. In order to provide objective measurement, this research compares the existing GT calculation method and numerical computation. The result reveals that both methods produced different GT, which is about 32% gap for fishing vessels in Muncar and 27% gap in Prigi.

      Abstract: Blue swimming crab (Portunus pelagicus) is an important economical fishery commodity for fishermen in Banten Bay that are caught using gill nets and collapsible traps. The increasing of fishing pressure has highly potential to reduce the quality of the catch as exposed in previous studies. However, the comprehensive, and time series analysis of the previous research results have not been conducted. The purpose of this study is to analyze the variations of blue swimming crab caught in Banten Bay through a combination of meta-analysis techniques, fishing trials and field obser-vations to determine the effect of fishing activities on swimming crab sizes, and evaluate the status of swimming crab fisheries in Banten Bay. Standard mean difference from 10 different studies was used as a meta-analysis parameter. The results of the meta-analysis showed that fishing activities were conducted from 2004 to 2018 had a significant effect on the decreasing of the swimming crab size. The average of swimming crab carapace width caught in 2019 approximately 121.66 mm. The proportion of legal swimming crabs in 2014, 2015 and 2019 was more than 80%, so that the status of swimming crab fisheries in Banten Bay is still environmentally friendly.

      Abstract: The blue swimming crab in the waters of Lancang Island is indicated as being overfished. Hence, the major challenge is managing its utilization in a proper manner. The purpose of this study is to explore the water's characteristics which is suitable for blue swimming crab fishing. Accordingly, the potential fishing ground around Lancang Island waters can be mapped spatially as an initial effort for species preservation. Geospatial analysis was applied to assess the physical parameters of the existing habitat. The results show that parameters such as MPT, TDS, brightness, phosphate, nitrate, depth and substrate types were remarkably suitable to support the growth of blue swimming crabs. Meanwhile, parameters such as salinity, DO, and temperature show lower quality which implied that the habitat is less suitable. However, the result of weighting and reclassification conclude that Lancang island waters is a decent habitat for blue swimming crab. Catch data show that 40% blue swimming crabs have small carapace size (7-11.83 cm) which is undersized and prohibited by law. Furthermore, about 68% of catch are quite light (30-147 gr) and the sex ratio of males to females was 1:2. It was also revealed that approximately 35% of female species were carrying eggs (BEF/barried female).

      Abstract: Agel ropes have lower mechanical properties (breaking strength and elongation) than synthetic fiber ropes. Chitosan coating is expected to improve the mechanical properties of agel ropes. The aims of this study are to investigate the effect of immersion in chitosan on the physical and mechanical properties of agel ropes, and to examine the breaking strength and elongation of coated agel ropes after being soaked in both freshwater and seawater. This experimental study was conducted at the Laboratory of Fishing Gear Technology, Department of Fisheries Resources Utilization IPB University, and Laboratory of Forest Product Engineering, Department of Forest Products IPB University. The experiment involved 3 mm in diameter of two agel ropes incorporating control rope and agel rope soaked in 1% chitosan for 24 hours. The control rope was light brown, stiff, and rough, while the treated rope was darker, less stiff, and smoother. The breaking strength of control and treated rope was significantly different (P<0.05), which in respect constitute 15.06 kgf and 24.54 kgf. The elongation of both ropes were also significantly different (P<0.05), making 10,56% for control and 18,04% for treated rope. Breaking strength of the agel rope decreased by 50% after being immersed for 28 days. Keywords: agel rope, chitosan, breaking strength, elongation

      Abstract: For design of marine propeller, the energy supply from marine engine to the propeller should be converted to thrust force with minimum losses. Furthermore, the unwanted vibration and cavitation due to the overlooking a detail calculation of the propeller should be prohibited for increasing the fuel efficiency and life-span of the propeller. In the last few decades, most of small and medium sized enterprises (SMEs) focusing their work on ship component industry in Central Java Province Indonesia provide the marine propeller to the ship manufacturer and ship repairmen in some shipyards in northern part of Central Java port. The design of the propeller is never been observed and optimized. The aim of the present work is to redesign the installed propeller on a wooden fishing boat with the new optimized design using B-Series propeller theory approach. The reverse engineering method uses three-dimensional scanner to obtain the geometrical data of the installed ship propeller. The new optimized propeller design is obtained from free software calculation based on the boat and engine specification. The comparison shows that the new optimized propeller design has a wider blade and larger pitch and increases 20% of the open water efficiency of the propeller performance at lower engine rotation.

      Abstract: Fishing port plays a vital role in providing fish raw materials (IBB) required for fish processing industries (IPI). The planning and development of IPI at Tasik Agung Rembang Coastal Fishing Port (PPP) rely on information regarding IBB supplies, however little data is available to support the decision. The purpose of this study was to investigate the origin of the IBB in fulfilling IPI demand for Pindang production and assess the IBB actual supplies (type, number, quality). A survey on the availability of IBB was conducted by involving various stakeholders including port officers, fishers, and IPI related entrepreneurs. Data collection consisted of both demand and supplies of IBB, which incorporate types, volume, and quality of fish. The results showed that the total demand for IBB was 824.8 ton/month and consisted of 9 species. However, the existing supplies of IBB only cover 59.5% of it.

      Abstract: A fishing operation is a dangerous and high risk activity. Stability of the vessel plays an important role in performing safely and successfully fishing operations. A brand new 30 GT purse seiner, production of a traditional shipyard in Batang Regency, experienced 15o heel after its launch. This condition potentially affects the stability of the vessel. The purpose of the study is to analyze the vessel stability and improve existing stability by adding outriggers. Research was conducted in two phases, data collection in the research site and stability analysed using a naval architecture software. The vessel stability was analyzed in six loading scenarios following the fishing operation process, subsequently the stability was compared against IMO standard. Results show that with the existing design, the vessel does not meet IMO criteria for the most applied scenarios. Next step, outriggers were added in both sides of the vessel model, as an effort to improve its stability. Accordingly, it is revealed that outriggers addition is scientifically proven to improve the stability of the studied vessel. As this research merely focused on the stability improvement, further analysis regarding maneuverability is required given a purse seiner operates encircled fishing gear.

    • Authors: Abdul Hamid, Syamsul Kamri
      Pages: 215 - 224
      Abstract: Information regarding the diversity of bycatch from blue swimming crab fishing operations is important in ecosystem-based management and assessment for Marine Stewardship Council (MSC) certification of crab fisheries in Southeast Sulawesi and Indonesia. However, data limitation becomes major challenges. This study aims to specify the types of bycatch caught from blue swimming crab fishing in Lasongko and Kendari Bay Southeast Sulawesi. This research was conducted in March to September 2019. Data was collected from trap and bottom gillnet fishing by using a purposive sampling method on a monthly basis. Bycatch was categorized into two groups, namely economically valuable and discarded, according to the local fishers’ perception. Information was presented both spatially and temporally. The results show that bycatch consists of 66 species including 42 economically valuable and 24 discarded species. Indices of diversity, evenness and dominance of fish were also discussed to describe the ecological conditions. Accordingly, this bycatch composition is able to support the management and assessment of MSC certification of crab fisheries in Southeast Sulawesi. Keywords: bycatch, fish diversity, blue swimming crab fisheries, Southeast Sulawesi.
