<p>PSP 01 is a training-fishing vessel that was built in a traditional dock yard in Palabuhanratu, so it was not completed with design drawings and stability calculation. This paper discusses on determining the vessel’s suitability of design and stability condition followed by redesign of main dimension to obtain more optimal design. Simulation carried out in various load conditions and different vessel sizes to get the considerably ideal size of the vessel. The main dimension ratio and coefficient of fineness analysis showed that the vessel was appropriate as multipurpose vessel for fishing activities. Stability condition of the vessel either empty or in existing load condition met the criteria recommended by IMO with a maximum GZ was 0.33 m and an initial GM was 0.64 m. To improve the stability and fish hold capacity, the breadth and depth needed to be increased. The redesign resulted an alternative size ofmain dimensions which were LOA = 14.30 m; B = 5.14 m; D = 2.12 m.</p><p><strong>Key words:</strong> design, fishing vessel, multipurpose, stability</p>

Purse seine is one of the fishing gear that has been used by PPN Muara Angke fisher to catch pelagis fish. The selectivity of purse seine was still being researched until now . This research was conducted  determine the selectivity of purse seine fishing gear with parameter the length of Euthynnus affinis, weight and numbers catch on purse seine fishing gear landed in PPN Muara Angke. The research used a survey method with quantitative descriptive analysis. The sampling method used in this was purposive sampling and random sampling. The data collected during the research were primary data and secondary data. Primary data included the number and weight of catches, fork length of Euthynnus affinis from five purse seine fishing vessel in PPN Muara Angke. Secondary data included production data of purse seine catches from 2015-2019 and vessel data obtained from Central Port Management Unit Jakarta and PPN Muara Angke. Purposive sampling used for the number of catch, weight of catch, production of purse seine catch from 2015-2019 and purse seine fishing vessels data. Random sampling used for fork length Euthynnus affinis fish, 250 samples were taken randomly on one purse seine fishing vessel. The research results pusre seine fishing gear which was landed at PPN Muara Angke was not selective due to the percentage length of the Euthynnus affinis was worth, proportion of amount and weight less than 60%.

The aim of this research is design and stability analysis Bulukumba purseseiner with three conditions cargo arrangement and two fishing seasons (peak fishing season and scarcity fisihing season). This research is done at Bulukumba regency, South Sulawesi province in February until April 2013 with measurements, observation and interview related of main dimension and cargo arrangement of Bulukumba purseseiner in field. Hydrostatic paramter analysis uses naval architecture formula and stability analysis uses PGZ software of three cargo arrangement conditions on two fishing seasons and then, these values will be compared with references value. The results of design analysis show that coefficient of finennes bulukumba purseseiner is Cb = 0.80 and Cp = 0.88 which its hull type bulukumba purseseiner is round bottom. Principal dimension ratio Bulukumba purseseiner have agreed with references of fishing vessel in Indonesia but it have not filled references of fishing vessel in Japan. The values of Bulukumba purseseiner stability have filled to IMO criteria of stability values. Stability of Bulukumba purseseiner on scarcity fishing season better than on peak fishing season and the best value of stability is PA-K3 condition (condition of purseseiner back to fishing base on scarcity fishing season).<br />Key words: Bulukumba, cargo arrangement, design, purseseiner, stability</p><p>-------</p><p>ABSTRAK<br />Kabupaten Bulukumba merupakan salah satu daerah pembuatan kapal kayu dan masih besifat tradisional.

Sustainability Analysis

Research of the sustainability analysis of fisheries resources by using trap net in the coastal ofPangkep Regency was conducted on August to October 2018 in the coastal zone of pangkep Regency.This research aims to 1) Analyze the location of trap net fishing areas, (2) Analyze environmentalfriendliness of trap net, (3) Analyze the sustainability of fish resources by using trap net in the coastalareas of Pangkep district. The method used was case study by following fishing operations using trapnet directly. Analyzed of the determination of the trap net installation location was used by geographicinformation systems (GIS), analyzed the selectivity of fishing gear used the formula based on theprovisions of FAO (1995), and analyzed the sustainability of fish resources used Rapfish analysis.Results of the research showed that fishing ground of using trap net covers the coastal areas ofPangkep Regency, there were four locations that have been determined based on analysis, which wereDistricts of Bungoro, Labakkang, Ma'rang, and Segeri. Trap net included in fishing gear that was notenvironmentally friendly, so it does not support the sustainability of fisheries resources. Utilization offishery resources by using a trap net in the coastal areas of Pangkep Regency is less sustainable.

This paper discusses on the static stability performance of a fishing vessel operated static fishing gear. A fishing boat named as KM PSP 01 was chosen as an object of this research. The objectives of this research were to analyze the static stability performance and work comfortability aboard the vessel. The result showed that KM PSP 01 was good enough for operating static fishing gear, the static stability of the boat is considered to be good with enough righting arm to upright the boat after roll to certain maximum angle. Hull of the boat considered as slim. Short rolling period i.e. 3.467 sec. considered as not so comfortable for working on deck but still safe in fishing operation.

Abstract The purse seine is the dominant fishing gear operating at the Tumumpa Fishing Port with a vessel of >90%. The purse seines that have developed are large pelagic targets, with the main catch targets being skipjack, mackerel tuna, and tuna. Tuna, mackerel tuna and skipjack are important commodities for fisheries in Indonesia. This study aims to determine the characteristics of purse seine fishing gear and its catch in the Sulawesi Sea. Data collection was carried out for two years from 2019-2020 at Tumumpa Fishery Port. Indications for the use of fish resources are calculated by comparing the length-at-first-capture (Lc) with the length-at-first-mature (Lm). The results showed that purse seines are very dominant in exploiting large pelagic resources (skipjack, mackerel tuna and tuna) with the proportion reaching 78%, small pelagic (21% scads and 1% other fish). The large pelagic fishing season using the purse seine vessel occurs in May – November, with 2 peak seasons in July and September. While the small pelagic occurs in May – September, with the peak occurring in July. The size when the frigate tuna was first caught was at a fork length of 25.15 cm (Lc) and Lm in a size of 28.52 cm for females and 28.29 cm for males. Meanwhile, the first scads was caught (Lc) at a length of 21.4 cm with the length-at-first-mature (Lm) being 20 cm for the female and 19 cm for the male. Based on this analysis, it was shown that the purse seines is a selective fishing gear for small pelagic fish but not selective for large pelagic fish.

This study aims to analyze the aspects of technical, social, and economic typologies of skipjack fisheries at Nizam Zachman oceanic fishing port, Jakarta. This research expected to provide information for decision-making in formulating policies in skipjack fisheries activities, thus they remain sustainable—this research conducted at Nizam Zachman oceanic fishing port, Jakarta from August 2019 to February 2020. The method used in this research is the survey method by interviewing the respondent through questionnaires for 100 respondents. The sampling method was done randomly, and the data were analyzed by descriptive qualitative. The social typology shows the orientation of Nizam Zachman as an industrial ocean fishing port is for commercial purposes. The main productive age level of fishers ranges from 35-39 years (33%) and the last education is a primary school (46%). Regarding the work experience, 38% had been fisher between 16-20 years. The technical typology shows the fishing gear that operated to catch skipjack at Nizam Zachman are purse seine, longline, also carrier vessel. In general, 74% of the size fleets were in 100-200 GT and the length of trips in 1-2 months (48%). The fishing ground area is in 572, 711 and 712 FMA. The economic typology shows skipjack production/trip by purse seine was 54%, longline (1%) and carrier vessel (57%).
