Evaluation of the Integrated Marine and Fisheries Center Development Program in Natuna Regency
type: item
description: This study aims to evaluate the implementation of the Integrated Marine and Fisheries Center Development Program (Sentra Kelautan dan Perikanan Terpadu or SKPT) in Natuna Regency, focusing on its benefits for fishers and coastal communities. A descriptive qualitative approach was used, involving in-depth interviews, observations, and documentation. The results show diverse perspectives among stakeholders. Some fishers and cooperative managers perceive the SKPT as beneficial in expanding market access and maintaining product quality; however, limited capital, low post-harvest skills, and weak institutional readiness remain major challenges. Meanwhile, officials from the Department of Marine and Fisheries and SKPT managers emphasize the need to improve inter-institutional coordination and landing regulations to optimize the program's effectiveness. The study also reveals protests and resistance from coastal communities, particularly traditional fishers, who feel disadvantaged due to reduced fishing zones and unequal distribution of aid. Furthermore, academic assessments indicate that the program’s success remains partial, with significant physical achievements but limited impact on broad economic welfare improvements. Based on these findings, it is concluded that the success of the SKPT requires a participatory approach, strengthening of local capacity, and continuous evaluation based on comprehensive evaluation models such as CIPP. The implications of this study highlight the importance of aligning physical, social, and economic development to achieve the goals of independence and sustainable welfare for Natuna’s coastal communities.

Effect of Type of Diluent on The Growth of Bacterial Colonies Bacillus sp. on The Isolation Process in Bacterial Culture
type: item
description: Bacillus sp. are bacteria that play an important role in shrimp farming, especially in maintaining the balance of the pond ecosystem and as probiotics. This study aims to determine the effect of the type of diluent on the number of Bacillus sp. colonies formed in the isolation process and determine the most effective diluent. Three types of diluents were used, namely distilled water, NaCl solution, and infusion water (NaCl 0.9%). This study used a completely randomized design (CRD) with 9 replicates in each treatment. The data obtained were analyzed using one-way ANOVA to determine the significance of differences between treatments, followed by Tukey test and LSD 5%. The results showed that distilled water produced the highest number of colonies (1711.56), followed by infusion water (1222) and NaCl solution (771.44). The ANOVA test showed highly significant differences (p<0.05) between treatments, with Tukey and LSD 5% test results supporting these findings. 0.9% infused water was proven to be an effective diluent for the isolation of Bacillus sp. which provides an accurate picture of the bacterial population, because growth is optimal and remains controlled. This study recommends the use of infusion solution in the process of bacterial isolation to be applied in pond culture, in order to improve water quality through the utilization of probiotic bacteria.

A Review of The Effectiveness of Fish Aggregating Devices (FADs) in Indonesian Waters
type: item
description: The utilization of Fish Aggregating Devices (FADs) in fisheries represents one of the most attractive and effective methods for increasing fishermen's catches. This review article aims to evaluate the use of FADs in enhancing sustainable catch outcomes and considers their role as an effective management tool. Various types of FADs have been designed and developed across different waters in Indonesia. There are several types of FADs commonly observed, including Squid FADs, Bio FADs, Sea urchins FADs, Electronic FADs, Bamboo raft FADs, Coconut leaf attractor FADs, Palm fiber attractor FADs, Light attractor FADs, FADs palm midrib, Rafia rope attractor FADs, Lubuk larangan FADs, and Fiber FADs. This paper reviews the different types of FADs, considering aspects such as the catch produced, technical specifications, and economic factors. Among these, portable FADs constructed from coconut leaves and raffia lines as attractors emerge as particularly effective and commonly used in Indonesian waters. FADs are also often combined with lift nets or electric fish attractors to enhance their effectiveness. Environmentally friendly fishing gears such as handlines and fishing rods are commonly operated around FADs. The types of fish caught typically include a mix of small and large pelagic species.

Catfish is only used as a fresh commodity without processing and preservation activities. One of the well-known preserved products is jambal roti. Jambal roti is a product of salt fermentation. This research aims to analyze the nutrition contents of jambal roti catfish, Sidenreng Rappang Regency, South Sulawesi. The research method used was experimental with a Completely Randomized Research Design. The treatment was long fermentation (24, 36, and 48 hours) at a salt concentration of 30%. The parameters observed were water content, salt content, protein, fat, and amino acids. The research results showed that the treatment given significantly affected water content, salt content, protein, fat, and amino acids. The best treatment is a fermentation period of 36 hours.

Monitoring Coastal Line Changes Using the Digital Shoreline Analysis System (DSAS) Method in the Coastal Area of Mekkatta Village, Mejene Regency
type: item
description: Analysis of coastline changes in Mekkata Village from 2013 to 2023 was conducted using the baseline of the nearest coastline to the mainland. This baseline was used as a reference point for transects measuring changes. The shoreline encompasses the coastline during the research period. Net Shoreline Movement (NSM) was employed to differentiate between erosion and accretion in the study area, showing an average shoreline change value of -9.72 meters towards the mainland, indicating predominant erosion. According to DSAS, it is observed that the coastline of Mekkata Village experienced erosion along 41 transects, while 31 transects exhibited accretion, highlighting significant changes. The most notable erosion area was identified along transects 60, 61, and 62, indicating consistent land reduction. Meanwhile, the most accretion-prone transects were 11, 12, and 13, signifying substantial land addition. The predominant erosion process is suspected to be influenced by the gentle slope of the coastal area and the composition of sand material. Human activities such as deforestation and river mouths also contribute to erosion. The absence of coastal protection structures allows direct waves and currents to impact the shore, potentially causing erosion. Meanwhile, accretion areas around river mouths indicate the formation of emergent land or deltas.

Scenario of Scleractinian Larva Dispersal in Sulawesi Waters From A Hydrodynamic Modeling Perspective
type: item
description: Scleractinian coral such as Lobophyllia corymbosa that reproduce by external fertilization have an extended planktonic phase in their life cycle during which they "drift" in the water column. This life cycle phase is an advantage in itself because it increases the capacity of propagules to disperse far from their place of origin. In this hydrodynamic model study, secondary data on bathymetry and tides for the western monsoon period (represented by November 2017) were input into the Surface Water Modelling System SMS 8.1 to simulate the surface current circulation model. In running this program there are 2 important stages, namely GFGEN (Geometry File Generation) and RMA2 (Resources Management Associates-2). The simulation of surface current direction during the west monsoon, which is the reproductive period of L. corymbosa in Indonesia, shows the complexity and distraction of current vectors that occur in the coastal waters around Sulawesi Island. The model results indicate the possibility of spatial and temporal biological networks forming in waters around Sulawesi. The current patterns forming in Sulawesi waters during the west monsoon tend to circulate from north to south due to the higher volume of water mass originating from the Pacific Ocean flowing to the southern part of Sulawesi which is also the entry point for the Indonesian Throughflow (ITF). The larval dispersion model scenario produced for each location (Manado, Toli-Toli, Palu, Mamuju, Spermonde, Sinjai, Wakatobi, and Luwuk Banggai) tended to follow the water movement patterns, with most propagules leaving the location where they were spawned.

Analysis of The Use of Rice Washing Water and Fermented Cassava Peel Waste on Population Growth of Daphnia Magna
type: item
description: Daphnia magna is a potential natural food source due to its nutritional content. The availability of Daphnia magna is not always consistent, posing a challenge to fish cultivation. An alternative solution is to use rice wash water and fermented cassava peel waste as a source of nutrition for Daphnia magna. Rice wash water contains soluble nutrients, while fermented cassava peel waste is rich in nutrients from the fermentation process. This research was conducted in the Fisheries Cultivation Laboratory, 1st Floor, Universitas Muhammadiyah Gresik, in April-May 2023. The research method employed was experimental with five treatments and three replications. P1= 0% rice wash water, 100% fermented cassava peel; P2= 25% rice wash water, 75% fermented cassava peel; P3= 50% rice wash water, 50% fermented cassava peel; P4= 75% rice wash water, 25% fermented cassava peel; P5= 100% rice wash water, 0% fermented cassava peel. Data analysis used analysis of variance and least significant difference test. The results showed that treatment P3 had the highest population density with an average of 2578 individuals. Additionally, treatment P3 also yielded the highest growth rate of Daphnia magna, reaching a value of 28.35. The population distribution across all treatments predominantly showed the total length class <100µm. Overall, the water quality within the temperature range of 26-28°C and pH range of 6.5-8 indicated optimal conditions for the growth of Daphnia magna.

ANALYSIS OF PREVALENCY, INTENSITY, AND CORELATION OF PARASITE WITH ENVIRONMENTAL CONDITIONS IN MILKFISH (Chanos chanos) IN TRADITIONAL POLYCULTURE PONDS OF KEDANYANG VILLAGE
type: item
description: This study aimed to examine the relationship between parasite prevalence in milkfish and water quality in the Traditional Fishponds of Kedanyang Village, Gresik Regency. The research was conducted for one month in April 2023. Random samples of milkfish were taken from two ponds, with a total of 40 fish. Parasite examination was performed by observing ectoparasites on mucus, gills, fins, and scales, as well as endoparasites in the fish's internal organs. The identification results revealed the presence of two types of parasites in the traditional polyculture ponds of Kedanyang Village, namely Dactylogyrus found in the gills and Cappilaria sp. found in the digestive tract. The prevalence and intensity of these parasites ranged from 2.5% to 5% and 1-2, respectively, which can be classified as low. The water quality in the ponds was categorized as good and well-tolerated by the fish. Correlation analysis showed that temperature, salinity, ammonia, nitrite, and nitrate had a weak positive relationship with parasite prevalence, while pH, dissolved oxygen (DO), and biochemical oxygen demand (BOD) had a weak negative relationship.

The Influence of Ocean Current Patterns on Surface Marine Debris Distribution In Makassar City Waters
type: item
description: A survey of the abundance and distribution of macro debris (>2.5 - <100 cm) and meso-debris (>0.5 – <2.5 cm) has been carried out in Makassar City waters. This research was carried out to map the distribution of surface marine debris following ocean current patterns. The macro debris abundance range is 2222-17222 items/km2 and the meso-debris range is 2222-30556 items/km2, with the dominance of 47,03% plastic debris for macro sizes and 49,74% wood debris for meso-sizes. The highest abundance was found at the Jeneberang estuary, then at the Losari Coastal Waters and the lowest at the mouth of the Tallo River. The current pattern in Makassar City waters at low or high tide tends to move from north to south towards the Jeneberang River estuary, with the current speed getting southern and slower. This condition causes a high abundance of macro and meso debris at the mouth of the Jeneberang River.

Spatial and Temporal Distribution of Skipjack and Little Tuna in Fisheries Management Area 713
type: item
description: Indonesian Fisheries Management Area (IFMA) 713 is a strategic and potential area for utilizing large pelagic fishery resources. In general, there are no fixed fishing grounds for large pelagic fish, and they are always changing and moving following the movement of environmental conditions, which naturally causes fish to choose a more suitable habitat. This study examines the distribution and abundance of skipjack tuna (Katsuwonus pelamis) and little tuna (Euthynnus sp) in relation to oceanographic conditions such as the distribution of sea surface temperature and sea surface chlorophyll-a concentrations in Indonesian Fisheries Management Area 713, which includes the Makassar Strait, Flores Sea, and Bone Bay. Based on the findings, skipjack tuna tends to be caught at warmer temperatures and higher chlorophyll-a concentrations than little tuna. Skipjack tuna tended to be distributed at a temperature of 29.84°C-30.28°C, which was associated with a chlorophyll-a concentration of 0.3 mg m-3, in contrast to little tuna, which was distributed at a temperature of 27.92°C-28.66°C with the most productive chlorophyll-a concentration (relatively high CPUE) of 0.2 mg m-3. This information on habitat distribution and optimum conditions of oceanographic parameters is very useful for the sustainable management of skipjack tuna and little tuna in the IFMA 713. in contrast to little tuna, which was distributed at a temperature of 27.92°C-28.66°C with the most productive chlorophyll-a concentration (relatively high CPUE) of 0.2 mg m-3.

SOCIAL ECONOMIC ANALYSIS OF ILLEGAL FISHING FISHERS IN SPERMONDE ISLAND
type: item
description: The sustainable use of fish resources is closely related to fishing practices by fishermen. It is a classic problem that utilizing marine and fishery resources, the exploitation method carried out by fishermen often does not consider environmental sustainability aspects or is contrary to the principles of responsible fisheries management (Code of Conduct for Responsible Fisheries - CCRF). This study aims to examine IUU fishing activities from the socio-economic dimension, which under certain conditions will produce its own understanding, especially when it comes to traditional rights, resource share allocation, and the level of dependence on fishery resources. The type of research is qualitative research with a case study method. Data collection techniques are observation, interviews, and literature study. The data collected includes primary data and secondary data. The data analysis technique used is the content analysis method through the stages of data reduction, data presentation, and drawing conclusions. The results of this study indicate that illegal fishing that occurs in the Spermonde Islands is dominant due to the pressure to fulfill economic needs, other factors are the low understanding of the importance of sustainable use of fishery resources; increasing demand for foreign markets, especially live fish; and inconsistency and weak law enforcement in preventing the use of explosives and drugs. Empirical data on resource potential is required and integrated into policy formulation in the form of responsible fisheries, including other activities that can be done by fishermen as alternative livelihoods, and ecosystem approaches for conservation and management of fish stocks of related species.

A PROFIT SHARING SYSTEM OF HAND LINE FISHERMEN AT HILA VILLAGE CENTRAL MALUKU DISTRICT
type: item
description: Income of hand line fisherman very dependent on the influence of nature and the existence of a working relationship between boat owners and labor fishermen in fishing operations. This study aims to analyze the profit-sharing and income-sharing system of hand line fishermen at Hila Village, Central Maluku District. Primary data was collected through interviews with 6 fishermen and analyzed using the business income equation and profit sharing system as well as the amount of income earned by fishermen. The results showed that hand line business income of Rp23.093.023/month and the application of the profitsharing system is 1:3 for owner fishermen, boats and 1 crew member. However, the boats's share becomes the property of the owner fisherman, so the owner fisherman gets 2 shares and the crew gets 1 share. The income obtained based on the profit sharing system is the owner of Rp15.393.349/month and the crew of Rp7.697.674/month.

type: item
description: Suckermouth catfish (Pterygoplichthys pardalis) are found in Lake Tempe, Wajo Regency, but their existence has not been utilized so far and is even considered the cause of the loss of several endemic fish species in the lake. This study aims to determine the chemical characteristics and the preference level of sticks fortified with Suckermouth catfish (Pterygoplichthys pardalis) meal as an effort to utilize these fish. The research method used was experimental with treatment of SK (control without adding Suckermouth catfish flour), S1 (addition of 10 g of Suckermouth catfish flour), S2 (addition of 20 g of Suckermouth catfish flour), and S3 (addition of 30 g of Suckermouth catfish flour). The parameters observed were moisture, protein, fat, carbohydrate, and ash content, and the level of preference (hedonic test). The results showed that the panelists tended to say they really like the appearance and flavour of the stick S1 product, and very much like the taste and texture of the stick S3 product. The highest protein and water content was in S3 treatment, the highest ash and carbohydrate content was in SK treatment, and the highest fat content was in S1 treatment

ANALYSIS OF THE CYSTOCARP DEVELOPMENT OF SEAWEED (Kappaphycus alvarezii) ON MEDIA ENRICHED WITH A COMBINATION OF NITROGEN AND PHOSPHATE
type: item
description: Seaweed (Kappaphycus alvarezii), in terms of providing seeds in cultivation activities, is still carried out vegetatively, namely cutting the thallus (cuttings), which is then cultivated until it is ready to be harvested (Rao & Reddy, 1997). However, such a method will experience problems, especially the provision of quality seeds on a large scale, and it does not depend on the season. The possible alternative to do is by generative seeding method. K. alvarezii can be developed for cultivation by utilizing the nature of generative reproduction through the development of carpospores, characterised by cystocarps on the surface of the thallus. However, the cystocarp that has been formed needs nutrients in the development process to produce spores of good quality and quantity. Nutrients that are needed to support cystocarp development include nitrogen and phosphate. The benefits of nitrogen and phosphate for seaweed growth cannot be replaced with other elements. This is due to the role of nitrogen as a constituent of protein and phosphate as an energy provider. This study aimed to determine the optimum nitrogen and phosphate enrichment ratio for cystocarp development. The research was carried out from November 2018 to February 2019 at the Seaweed Laboratory of the Takalar Brackish Aquaculture Fisheries Center (BPBAPT). The research location is Mappakalompo Village, Galesong District, Takalar Regency, South Sulawesi Province. They were analyzed at the water quality laboratory of Hasanuddin University to analyse the N and P content in the media. There were 6 treatments with 3 replications each, namely Treatment A: Without enrichment (SW), Treatment B: 1N=0.5 ppm: 1P=0.5 ppm, Treatment C: 2N=1 ppm: 1P= 0,5 ppm, Treatment D : 3N=1,5 ppm : 1P=0,5 ppm, Treatment E : 1N=0,5 ppm: 2P = 1 ppm, and Treatment F : 1N=0,5 ppm : 3P = 1.5 ppm. The results showed that the development of a shorter cystocarp phase was found in treatment D, which was 14 days. Meanwhile, treatment with a lo…

Macrozoobentos Community Structure at Ecoshrimp Reservoir Pond, Waetuoe Village, Lanrisang District, Pinrang Regency
type: item
description: Mollusc has great commercial benefits in capture fisheries and aquaculture. However, it can also cause economic losses and human suffering. Some macrozoobenthos of the mollusc species are intermediate hosts for parasites and pests in aquaculture pond systems. The reservoir in the pond is a sedimentation area and a biofilter to optimize water quality before flowing into the pond. This study aims to analyze macrozoobenthos community structure at the ecoshrimp reservoir pond located in Waetuoe Village, Lanrisang District, Pinrang. Macrozoobenthos sampling was carried out using a 1x1 m quadrant-transect. The results showed that the identified molluscs consisted of eight species grouped into four families and two classes, including Gastropods and Bivalves. The abundance of macrozoobenthos at the pond's edge was smaller than those in the middle part (994 individuals vs. 1095 individuals). Sermyla requtii was the species with the highest density of 350 ind/m2 at the edge and 670 ind/m2 in the middle of the reservoir. The frequency of occurrence of macrozoobenthos at both observation sites has a value of > 25%.
