Food Supply Chain Network (FSCN) Analysis of Traditional Smoked Fish Enterprises in Bone Regency: Structure and Risks
type: item
description: Traditional smoked fish enterprises play an important role in supporting the livelihoods of coastal communities. However, the highly perishable nature of fish products poses significant challenges to the supply chain, including uncertainty in raw material availability, limited coordination among supply chain actors, and distribution risks. This study aimed to analyse the Food Supply Chain Network (FSCN) of traditional smoked fish enterprises in Bone Regency, Indonesia, by examining the network structure, supply chain management, business processes, resources, product, information, and financial flows, as well as identifying key bottlenecks and supply chain risks. A descriptive research approach was employed through field observations and interviews with 38 traditional smoked fish producers selected using the census method as the primary respondents. The analysis was further supported by information obtained from other supply chain actors to provide a comprehensive FSCN assessment. The results revealed that the smoked fish supply chain consists of five main actors: fishers, raw material suppliers, smoked fish producers, retailers, and end consumers, supported by secondary actors providing production facilities and supporting services. Smoked fish producers serve as the central actors by transforming fresh fish into value-added smoked fish products. Product flows move from fishers and suppliers to producers and subsequently to retailers and end consumers. Information flows occur bidirectionally among supply chain actors, while financial flows move upstream from consumers through predominantly cash-based transactions founded on mutual trust. The business processes encompass raw material procurement, production, inventory replenishment, and customer order fulfilment. FSCN analysis identified raw material supply as the primary key bottleneck, primarily due to dependence on capture fisheries, where seasonal variation and adverse weather conditions disrupt the continuity o…

Productivity of FAD-Based Purse Seine Fisheries and Its Relationship with Oceanographic Variability in the Makassar Strait
type: item
description: The Makassar Strait is one of Indonesia’s productive fishing grounds and serves as an important operational area for FAD-associated purse seine fisheries. The productivity of pelagic fisheries in this region is influenced by the use of fish aggregating devices (FADs) and oceanographic conditions that affect fish distribution and abundance. This study aimed to analyze catch composition, estimate fishing productivity using Catch Per Unit Effort (CPUE), and examine its relationship with oceanographic parameters in the Makassar Strait. The research was conducted from September to November 2025 at the Lero Fish Landing Base (PPI Lero), Pinrang Regency, South Sulawesi. Primary data were collected through field observations, catch recording, fishing-trip monitoring, and fishing ground. Oceanographic data, including sea surface temperature (SST), chlorophyll-a, salinity, and current velocity, were obtained from MODIS satellite imagery and the Copernicus Marine Data Store. Data were analyzed descriptively for catch composition, while CPUE was used to evaluate fishing productivity and its association with oceanographic variables. The results showed that the catch was dominated by skipjack tuna (Katsuwonus pelamis), kawakawa (Euthynnus affinis), and scads (Decapterus spp.). Total catch reached 48,638 kg from 17 fishing trips, resulting in a CPUE value of 2,861.06 kg trip⁻¹. The highest catches were associated with SST of 30.6–30.8°C, salinity of 33.80–33.89 ppt, chlorophyll-a concentrations of 0.13–0.19 mg m⁻³, and current velocities of 0.85–1.04 m s⁻¹. These findings indicate that purse seine productivity is influenced by the interaction between FAD deployment and favorable oceanographic conditions that support pelagic fish aggregation.

Analysis of Land and Water Use Efficiency: Transforming Traditional Earthen Ponds into Recirculating Aquaculture Systems (RAS)
type: item
description: The aquaculture sector in Indonesia faces significant challenges due to the reduction of productive land and the degradation of surface water quality. This study aims to evaluate the effectiveness of transforming conventional earthen pond cultivation systems into Recirculating Aquaculture Systems (RAS) through a comprehensive analysis of land and water use efficiency. The method employed is a quantitative and qualitative descriptive approach via systematic literature review (SLR), adapting the PRISMA guidelines. Secondary data were extracted from 10 primary scientific articles published between 2016 and 2026. The results indicate that RAS technology enables extreme intensification of stocking density up to 2,000 fish/m³, significantly outperforming conventional earthen ponds (±100 fish/m³). The filtration system in RAS is proven to maintain optimal water quality stability, with very low ammonia levels (<0.01 mg/L) and high dissolved oxygen (6.0–7.2 mg/L). These conditions drive the Specific Growth Rate (SGR) to reach 2.68% and optimize the Food Conversion Ratio (FCR) to 1.08. Economically, despite high initial capital expenditure, RAS demonstrates long-term feasibility with a Payback Period of less than 4 years at an optimal commercial scale. In conclusion, the transformation to RAS technology is a strategic solution that offers superior technical, biological, and economic benefits, while ensuring ecosystem sustainability through a zero-waste concept.

FRP Ship Hull Strength Performance at the UD Wahyu Asih Fiberglass People's Shipyard, Kebumen
type: item
description: The UD Wahyu Asih Fiberglass community shipyard has produced various types of FRP ships; however, the manufacturing process does not adhere to the construction standards set by the Indonesian Classification Bureau (BKI) and still relies on the independent experience of the business owner. Additionally, this shipyard lacks scientific evidence regarding the strength of the FRP ship hull structures it produces. This study aims to describe the stages of ship construction and the materials used, as well as determine the value of material strength through tensile tests, compressive tests, and the elastic modulus of the FRP ship hull structure. Data collection was conducted through literature studies, field observations, specimen creation, and mechanical property testing of materials, and then analyzed using a descriptive-comparative approach. The results of the study showed that the materials used in the manufacture of FRP ships include Yukalac 235 resin, Yukalac G-123 T-EX gelcoat, CSM300, WR600, WR800 fibers, and additives such as Mepoxe catalyst, cobalt napthanate, pyrogenic silica, talc, Matapel Unipol dye, miracle gloss, kerosene, ivory rubbing compound, and kit (compound). The ship construction process was carried out in two main stages: lamination and finishing, utilizing hand lay-up techniques. Although the tensile strength value has met the minimum BKI standard, the compressive strength and elastic modulus values ​​obtained are still below the limits set by BKI. Based on the results of this study, ships built at the UD Wahyu Asih Fiberglass shipyard can be recommended to the Ministry of Maritime Affairs and Fisheries for the procurement of aid ships, provided that their tensile strength and elastic modulus are improved.

Literature Review of Identification and Understanding of Microplastics Contamination in The Biosphere
type: item
description: Microplastics are plastic particles with a size less than 5 mm which pose a growing concern in terms of ecotoxicology in aquatic environments and human health. Despite the widespread presence of microplastic pollution in land, water, and air, these environments are often viewed in isolation, although they are intricately interconnected. This study endeavors to examine the existing scientific literature pertaining to microplastic research across various environmental compartments and identify research gaps to shape future priorities. Scientific papers addressing microplastic pollution, published between 2014 and 2023, have been identified in the Web of Science database. Original research articles categorized under Environmental Sciences, Marine/Freshwater Biology, Toxicology, Multidisciplinary Sciences, Environmental Studies, Oceanography, Limnology, and Ecology in the Web of Science are chosen for a detailed investigation into microplastic research in seas, estuaries, rivers, lakes, soil, and the atmosphere. The selected papers for seas, estuaries, rivers, and lakes are further categorized based on (i) occurrence and characterization, (ii) uptake by and effects on organisms, and (iii) issues related to fate and transport. The findings indicate that, despite significant scientific research on marine microplastics, our understanding of the extent of microplastic pollution in continental environments, including rivers, lakes, soil, and air, as well as the associated environmental interactions, remains limited.

Evaluation of Nutritional Composition and Lead Detection in Suckermouth Catfish (Pterygoplichthys sp.) Egg Flour as a Candidate Feed Additive for Fish Feed
type: item
description: This study aims to evaluate the nutritional value and heavy metal lead (Pb) content in suckermouth catfish (Pterygoplichthys sp.) egg meal as a candidate feed additive in fish feed. The fish eggs were obtained from fishermen's catches in public waters in East Java, then cleaned, dried, and processed into meal for analysis. The proximate parameters tested included protein, fat, crude fiber, and ash content using the AOAC standard method, while Pb content was analyzed using Atomic Absorption Spectrophotometry (AAS). The results showed that suckermouth catfish egg meal had the following nutritional composition: protein 39.25±0.02%, fat 9.19±0.01%, crude fiber 2.36±0.03%, and ash 4.95±0.02%. This nutritional profile indicates that suckermouth catfish eggs are a high source of animal protein and have a low fiber content, thus having the potential to improve feed quality through the addition of essential amino acids and energy. Heavy metal Pb content was not detected within the sensitivity limits of the instrument, thus this product meets the safety aspects of feed ingredients related to heavy metal contamination. Overall, the results of this study indicate that suckermouth catfish egg meal has competitive nutritional value compared to several conventional feed ingredients and is safe from Pb contamination. Thus, this ingredient has the potential to be developed as an alternative feed additive in fish feed formulations.

Supply Chain Performance Analysis of Catfish Farmers in Kediri Case Study on Fish Hatchery
type: item
description: This study aims to analyze the supply chain system in catfish farming in Kediri, focusing on three main aspects: the flow of goods, financial flow, and information flow. It also aims to identify the actors involved in the supply chain and determine the appropriate supply chain model. This research was conducted from March to July 2025 among four catfish farmers in Kediri city and regency. The method used is a case study approach with interviews with four business actors consisting of catfish breeders and growers. The data analysis used exploratory descriptive analysis, explaining the actors involved in the supply chain, the flow of goods, the flow of money, and the flow of information in the form of graphs, tables, and figures. The results show that the flow of goods is dominated by an informal distribution network through middlemen, with distribution patterns varying between business actors depending on the type of business. With minimal intervention from the credit system and a high degree of trust between actors, financial flow occurs easily through cash and transfer channels. Without written contracts, information is communicated directly between people, making it less formal yet more flexible. The resulting supply chain model is a trust-based supply chain in which players cooperation is primarily driven by their social relationships. In order to increase the effectiveness, sustainability, and transparency of the supply chain for catfish farming in Kediri, this study suggests that institutional assistance and technology integration are necessary.

Perception Analysis of The Impact of Shrimp Pond Waste on The Income of Small-Scale Fisheries in Mallusetasi District, Barru Regency
type: item
description: Small-scale fisheries play a strategic role in the blue economy and food security in coastal regions. In Mallusetasi District, fishers still rely on traditional and environmentally friendly fishing gear, yet they remain vulnerable to changes in coastal ecosystems, including shrimp farming activities. This study aims to analyze the perceptions of small-scale fishers regarding the impact of shrimp pond waste on their income. A total of 40 respondents were selected through purposive sampling, and data were analyzed using a Likert scale and Spearman correlation. The Likert scale analysis produced a total score of 552, indicating that fishers perceive a decline in catch volume and income due to waste discharge and expansion of shrimp farms. However, the Spearman correlation test revealed no statistically significant relationship between shrimp farming activities and the income of small-scale fishers. These findings indicate a discrepancy between environmental perceptions and actual economic conditions, suggesting that fishers are able to adapt and maintain their income through various coping strategies. Further investigation is required to better understand the socio-economic adaptation dynamics of small-scale fishers amid the pressures of coastal aquaculture activities.

Growth and Population Dynamics of Daphnia sp. on Different Fermented Nutrient Sources
type: item
description: Chicken manure is an organic material rich in nutrients and can be fermented using specific microbes to break down complex compounds into simpler forms. This fermentation process enhances the availability of nutrients that are more easily absorbed by aquatic organisms such as Daphnia sp., supporting their growth. This study aimed to evaluate the effect of different nutrient treatments on the growth and population dynamics of Daphnia sp. Three treatments were tested: unfermented chicken manure (A), chicken manure fermented with EM4 (B), and chicken manure fermented with yeast (C), each with four replications. A total of 100 g of chicken manure was fermented for three days before being used as a culture medium for Daphnia sp. The cultivation of Daphnia sp. lasted for 12 days in 2 liters of clean water per container, with an initial density of 50 individuals/L. Parameters observed included daily population growth and the timing of peak population. The results showed that treatment B (chicken manure fermented with EM4) produced a significantly higher population growth rate (P < 0.05). Meanwhile, the peak population of Daphnia sp. was observed simultaneously on day 9 across all treatments, based on descriptive observations. The population began increasing from the first day after stocking, peaked on day 9, and then declined until day 12 (end of the study). Water quality parameters during the study remained within a suitable range for Daphnia sp. growth. Therefore, fermentation of chicken manure using EM4 has the potential to improve the efficiency of Daphnia sp. population growth.

The Role of Social Capital in Production Decision Making and Production Relations among Seaweed Farmers in Punaga Village, Takalar Regency
type: item
description: This study aims to analyze the role of social capital in production decision-making and the formation of production relations among seaweed farmers in Punaga Village, South Sulawesi. A qualitative approach was employed using participant observation, in-depth interviews, and document analysis. The findings indicate that trust, communal norms, and local social networks are central to seaweed farming practices. Social capital functions as a mechanism for information exchange, access to production inputs, and collective labor arrangements. However, the research also reveals that strong social capital fosters patron client relationships that reinforce the dominance of punggawa/pappalele in controlling capital and distribution channels. Closed social networks produce exclusivity and limit economic mobility for new farmers. These findings suggest that social capital is ambivalent: while it supports social cohesion, it also reproduces structural inequality. Strengthening local institutions and developing more inclusive social capital are essential to promoting independence and equity in aquaculture production systems.

Effect of Different Fish Species on Growth of Fish in a Bucket Culture System (Budidamber)
type: item
description: This study aims to analyze the effect of different fish species on fish growth in a bucket aquaculture system (Budidamber). The study was conducted from July to September 2024 at the Dry Land Aquaculture Laboratory, Nusa Cendana University, Kupang, using 60 catfish (Clarias gariepinus), 60 tilapia (Oreochromis niloticus), and 60 patin fish (Pangasius sp.) with an average weight of ±10 grams and an average length of ±8 cm. The study used a completely randomized design (CRD) with three types of treatments, each repeated three times. The treatments were A (catfish), B (tilapia), and C (pangasius). The parameters observed included absolute weight gain, absolute length gain, and fish survival. The results of the analysis showed that the catfish treatment had a significant effect (P<0.05) on absolute weight gain. However, for the parameters of length increase and survival, no significant differences were found (P>0.05) between the three types of fish.

The Effect of Sample Preparation, Extraction Duration, and Precipitant Toward Carrageenan Characteristics which Extracted from Kappaphycus alvarezii
type: item
description: Carrageenan is a polysaccharide compound product produced from carrageenophyte seaweed extraction, one of which is Kappaphycus alvarezii. The yield and other characteristics are conventionally produced from an extraction process and have different results. This study aims to explore and optimize the characteristics of carrageenan produced by treating sample preparation with two types of precipitants at specific concentrations, setting the timing during the extraction process, and examining the interaction of these three treatments on the carrageenan characteristics. The results obtained showed that the yield value, acid-insoluble ash (AIA) content, and viscosity were influenced by the preparation method, specifically by chopping the seaweed before extraction. Additionally, the characteristics of the gel strength were influenced by the preparation method, specifically by blending the seaweed. The use of KCl precipitant affects the water content, AIA content, and viscosity, while the CaCl₂ precipitant affects the yield value and gel strength. 1-hour extraction process affected the characteristics of carrageenan for AIA content and gel strength, while extraction for 2 hours affected the yield value, water content, and viscosity. The interaction of 8% KOH solvent by cutting sample treatment, extracted for 2 hours and using KCl precipitant, produced good carrageenan characteristics for water content, AIA content, and viscosity.

Indonesian Blue Economy for Sustainable Fisheries
type: item
description: Blue economy is a management system for all aquatic ecosystem resources, including marine and terrestrial ecosystems, related to economic value, sustainability of ecosystems and production resources, and distribution of benefits. The adoption of this concept in Indonesia uses the term inclusive and sustainable blue economy to emphasize the equitable distribution of benefits from the development of the blue economy by ensuring the sustainability of its carrying capacity. This paper explains the importance of managing Indonesian fisheries resources based on the blue economy concept to ensure the sustainability of existing fisheries resources. The literature study method issued by agencies and strategic stakeholders is the primary reference in this study. In this study, it was found that the significant challenges faced were the problem of environmental damage due to illegal activities such as illegal fishing, damage to mangrove forests, seagrass ecosystems, coral reefs, and production activities and the fisheries industry that often pays little attention to sustainability aspects so that it is deemed necessary to implement sustainable fisheries management policies that must focus on several urgent matters to achieve Indonesia's blue economy goals. Based on this, as a role model for research purposes, recommendations and research efforts have been made with a roadmap for the sustainable use of pelagic fisheries resources based on Indonesia's blue economy program in the Bone Bay area. Sustainable fisheries management based on the blue economy concept can be developed and applied well through collaboration and synergy with all existing stakeholders consisting of the government, universities, NGOs, and fishing communities.

type: item
description: The purpose of this study was to analyze the effect of adding commercial feed with various concentrations of the hormone thyroxine (T4) on the growth profile of star pomfret (T. Blochii, Lacapede). This research was conducted for 50 days at BPBL Sekotong. The method used is an experimental method with a completely randomized design (CRD) which includes 4 treatment levels and 3 replications. consisting of: P1: control (without thyroxine hormone), P2: thyroxine hormone 1 mg/kg feed, P3: thyroxine hormone 1.5 mg/kg feed, P4: thyroxine hormone 2 mg/kg feed. Parameters measured were absolute weight, absolute length, specific growth rate (SGR), feed efficiency (EP), feed conversion ratio (FCR), survival (SR) and water quality. Data were analyzed using variance (ANNOVA) and continued with Duncan's test. The addition of the concentration of thyroxone hormone (T4) in commercial feed can affect the growth of star pomfret but does not affect the value of feed utilization efficiency (EPP), feed conversion (FCR) and survival (SR). The addition of the concentration of thyroxine hormone (T4) 2 mg/kg in commercial feed is the best treatment in star pomfret culture, because it can provide an absolute weight of 7.69 g, an absolute length of 3.50 cm, and a specific growth rate of 2.28%/day.

A Review on Chicken Feather Flour Potential for Fish Feed
type: item
description: The escalating demand for chicken meat over the years has led to a corresponding increase in waste generation, particularly chicken feathers. While efforts such as making dusters and cocks have been undertaken to address this issue, they have yielded limited success in effectively managing chicken feather waste. Given the significant levels of nutrients, including protein and amino acids, present in this waste, it holds immense potential as a raw material for fish feed. However, the utilization of chicken feather waste remains relatively uncommon due to the challenging digestibility of its large crude protein structure, primarily composed of keratin protein. Thus, preprocessing is essential to degrade the keratin within chicken feathers, rendering it digestible for fish. This review aims to provide an overview of the potential utilization of chicken feather meal in aquaculture, particularly in fish feed formulations, by exploring its nutritional value and various processing methods to enhance the quality of this raw material.

Development Center of Minapolitan Area in Wajo District
type: item
description: Regional development with a Minapolitan concept is part of the marine and fisheries industrialization policy strategy which aims to realize accelerated increases in the income of cultivators, fishermen, processors, and marketers by integrating upstream and downstream production systems to increase the scale and quality of production, productivity, competitiveness and added value for sustainable marine and fisheries resources. The Minapolitan program is designed to increase the competitiveness of fisheries commodities which is then targeted to increase regional competitiveness and reduce the gap between urban and rural areas. This activity is intended to formulate a development center for the Minapolitan area of ​​Wajo District which will become the basis for preparing technical work plans for related agencies. Based on field results, it was found that the marine and fisheries resource potential of Wajo District was mapped into two resource potential zones, namely (1) the coastal subdistrict area (Bola, Takkalalla, Sajoanging, Penrang, Keera and Pitumpanua subdistricts) which is directly connected to the waters of Bone Gulf for the utilization of potential resources of capture fisheries and aquaculture (marine cultivation and pond cultivation); and inland fisheries areas, especially in the Tempe lake area (Sabangparu, Tempe, Tanasitolo and Belawa subdistricts). Utilization of the potential of the coastal areas of the District of Wajo, with its characteristics of an open water area directly bordering Gulf of Bone, has more potential for the development of capture fisheries, marine aquaculture, and brackish/pond cultivation with the superior commodities of seaweed and mangrove crabs as well as coastal ecotourism. Meanwhile, the Tempe Lake area is more geared towards fishing, cultivating freshwater fish and limited area management for ecotourism activities.
