Abstract

Mangrove crab (Scylla serrata) was one of the fisheries export commodities and also got high demand in traditional markets, mini markets, and supermarkets. Inadequate storage and inappropriate handling during processing lead to decreasing weight and quality of mangrove crabs. The present study aims to investigate the effectiveness of different preservation methods of mangrove crabs on quality and physicochemicals to inhibit quality deterioration. The preservation methods are cold, frozen, and live and the period of storage is between 0, 2, 5, 8, and 12 days. The obtained result showed that frozen storage is longer than cold and lived storage to maintain quality (organoleptic, moisture level, TVB, and pH). Mangrove crabs are kept alive is better than frozen and cold storage to maintain weight loss.

Abstract

Coastal areas with mangrove forests are a natural landscape that has a unique environmental tone. In the past, this coastal area was a landing place for traders and religious leaders to preach. Developing this area into religious ecotourism is an economic potential that should be grown from integrated marine space management with sustainable exploration of coastal resources. The research aims to develop implementation strategy stages for the development of religious ecotourism in coastal areas and mangrove forests in the Southeast Asia region. Descriptive research with a qualitative approach. Data was obtained from cross-information between researchers at four different locations. Each researcher obtained empirical data from interviews and direct observations in the field. The implementation strategy was prepared using SWOT-BSC analysis with a combination of weightings, where each researcher reported the two most important aspects in the implementation feasibility approach based on observations at each of their nearest residential locations. Collaborative research provides general results that contain a compilation of different strategies. Aspects of the religious approach and aspects of revitalizing the role of coastal communities and indigenous communities are the main things that must be prioritized from the start to realize religious ecotourism so that it becomes a leading tourist destination in an area.

Abstract

Purse seine or purse seine is one of the dominant fishing tools for catching pelagic (surface) fish which operates by circling schools (schooling) of fish. In the process of circling a school of fish, the bottom must be crimped immediately and quickly using a crimping rope or what is usually called a "drawstring" so that the fish remain in the circle and do not escape. This research was conducted from August to October 2019 on the north coast of Pekalongan, Java Sea. The application of hydraulically powered capstan axle crimp rope pulling machines on small scale vessels is expected to increase effectiveness, operational safety and efficiency of time and energy. Especially for purse seine ships <30GT and can increase catches which in turn can increase fishermen's income. Based on the test results, it was found that the driving diesel RPM without a pulling load = 1303 / 1530 RPM; Maximum RPM of the winding capstan spool when without a pulling load = 45 / 51.5 RPM; Maximum speed of winding capstan spools without tension load = 40.5 / 58.5 meters/minute; RPM of the driving diesel when pulling the purse seine line = 1500 RPM; Maximum RPM of the capstan winder spool when pulling the purse seine line at an average load = 43.2 RPM; Maximum RPM of the capstan winder spool when pulling the heaviest load (maximum) purse seine crimp rope = 40.1 RPM; Maximum pulling speed of the towing machine at the average load of pulling the purse seine crimp rope = 40.07 meters/minute; Maximum pulling speed of the towing machine when the heaviest load is pulling the purse seine crimp rope = 37.2 meters/minute; Load towing capability = detected ± 1000kg.

Abstract

Commercial use of milkfish as a raw material for processing crackers generally only uses the meat part, while the head and bones have not been used much so far and have even been disposed of as waste. This research aims to determine consumer acceptance of crackers made from milkfish by using the head and bones as raw materials to substitute for the meat. The head and bones of the milkfish are processed into finely ground (LKT), then substituted for milkfish meat as raw material for crackers. The treatment used was the number of LKT substitutions for milkfish meat, namely 10% (S1), 20% (S2), 30% (S3), 40% (S4), 50% (S5) and control, namely without substitution (S0). The results show that panelists prefer S2 with a preference value for color 5.3 (rather like), aroma 4.8 (rather like), texture 6.0 (like), taste 5.9 (like), and overall 5.5 (Like). The physicochemical characteristics of S2 have a swelling volume rate of 817%, hygroscopicity of 7.23%, moisture of 10.19%, protein of 17.19%, ash of 5.86%, and fat of 0.29%.

Abstract

Salt is a product from marine resources which is a strategic commodity as an industrial raw material and food for the community. However, the condition of national salting is currently still not conducive, this is because salt production, both quantity and quality, is still insufficient and sufficient to meet national salt needs. This research aims to compare the effectiveness of traditional techniques and heating techniques in aging seawater for the seawater crystallization process in making salt. With this research, it is hoped that there will be the latest technological innovations to speed up the time for making salt with maintained quality, good quantity and profit so that national salt needs can be met. From this research it can be concluded that the use of heating techniques is more effective than traditional techniques because it can minimize the aging time of sea water and can increase the quantity of salt produced.

Abstract

Fish bones are a by-product or waste from fish processing, both on a small and large scale. Many efforts have been made to utilize these bones by converting them into bone meal. The use of the pressure hydrolysis method in the production of fish bone meal can produce high-quality products. This study aimed to determine the quality of the mackerel tuna bone meal using the pressure hydrolysis method. The data obtained were then discussed descriptively and qualitatively. The results showed that the pressure hydrolysis method effectively produced mackerel tuna bone meal. The highest yield of mackerel tuna bone meal was obtained in the TT2 treatment with a heating time of 2 hours. The bone meal produced had moisture content ranging from 6.58% to 8.76%, ash content ranging from 96.86% to 98.82%, and organoleptic values such as odor, texture, and color were acceptable to the panelists. During storage for 3 days at room temperature, there was mold growth of Aspergillus flavus and Aspergillus penicillium in the range of 1.25×102 to 1.45×102 colonies per gram and met the minimum standards set by the Indonesian National Standard (SNI).

Abstract

The presence of plankton is very important for aquatic ecosystems. Kalianda Coastal Beach has direct access to the open sea. Its water condition can experience changes including physical, chemical, and biological conditions. Moreover, the beaches in the Kalianda coastal area are widely used for vannamei shrimp breeding, ferry port, fishery and trade port. The purpose of this study was to evaluate the structure of the plankton community, including abundance and species composition, diversity index, uniformity, and dominance. This study used data from water sources in three vannamei shrimp nurseries located in Kalianda Coastal Beach, South Lampung. Water parameters observed in Kalianda Coastal were plankton, salinity, pH, nitrate, ammonia, dissolved solids (TSS), and phosphate. The results showed that the plankton found in Kalianda coastal area consisted of four classes, phytoplankton namely Bacillariophyceae (78.75%) and Dynophyceae (9.85%), zooplankton Ciliata (7.79%) and Crustacea (3.61%). The range of phytoplankton abundance is 2392-3029 cells/l, while the abundance of zooplankton is 279-414 ind/l. Plankton diversity and uniformity indices are high meaning that the plankton community in Kalianda Coast is very diverse and stable, low dominance means that there are plankton that dominate, namely from the Bacillariophyceae class. The structure of the plankton community in Kalianda Coastal Beach shows a stable condition at the time of the research. To know the plankton community structure more thoroughly, it is necessary to take plankton samples every season with more station points.

Abstract

Purse seine is a type of fishing gear that has the principle of catching fish by circling a school of fish. Fish caught by purse seine include lemuru, skipjack, and tuna (pelagic fish), which have economic value. One area where the majority of fishermen use purse seines is PPS Kendari. The more fishermen use the purse seine, the more it will affect the income or feasibility of the fishing business. The feasibility status of the business can be identified by conducting a business analysis of the fishing activity. Business analysis begins with participating in a trip to one of the purse seine fishing activities at PPS Kendari in January-May 2020. Carry out business-related recording activities (business capital, maintenance, and income). After the data is obtained, a business analysis will be carried out on the profit value, profit sharing system, R/C ratio, and payback period (PP). Based on the business analysis that has been done, the total cost of fishing activities is Rp. 212,716,600.00, and the company made a profit of Rp. 1,074,353,400.00. profit-sharing system, with each share amounting to Rp. 20,270,818.87. So, it can be said that fishing using purse seines at PPS Kendari is still feasible, with a value of 6.05 and a PP of 0.61 years.
