Food Supply Chain Network (FSCN) Analysis of Traditional Smoked Fish Enterprises in Bone Regency: Structure and Risks
Traditional smoked fish enterprises are an important economic activity supporting the livelihoods of coastal communities. However, the perishable nature of fishery products causes the supply chain to face various challenges, including uncertainty in raw material supply, limited coordination, and distribution risks. This study aimed to analyze the Food Supply Chain Network (FSCN) of traditional smoked fish enterprises in Bone Regency, Indonesia, by examining the supply chain structure, supply chain management, business processes, resources, product, information, and financial flows, as well as identifying key bottlenecks and supply chain risks. This study employed a qualitative method using the FSCN approach and was conducted from November 10, 2023, to January 12, 2024. Data were obtained through observations, interviews with 38 smoked fish producers selected using a census method as the primary respondents, and in-depth interviews with 20 other supply chain actors selected purposively as supporting informants. Data were analyzed descriptively using the FSCN framework, covering supply chain structure, supply chain management, business processes, resources, product, information, and financial flows, as well as the identification of key bottlenecks and supply chain risks. The results showed that the smoked fish supply chain network in Bone Regency consisted of five main actors: fishers, raw material suppliers, smoked fish producers, traders/retailers, and final consumers, supported by secondary members providing production inputs. Producers served as central actors that created added value through the processing of fresh fish into smoked fish products. Product flow moved from fishers and suppliers to producers and was subsequently distributed through traders/retailers to final consumers. Information flow was bidirectional, whereas financial flow moved from downstream to upstream, with transactions predominantly conducted on a cash and trust-based basis. Business processes included raw material procurement, production, replenishment, and customer order fulfillment. FSCN analysis identified raw material supply as the main key bottleneck due to dependence on fishers’ catches, which are influenced by seasonal and weather conditions, compounded by limited processing technology and the risk of quality deterioration during distribution. These findings indicate that strengthening raw material supply continuity, improving coordination among supply chain actors, and enhancing institutional integration are key strategies for improving the resilience and sustainability of the traditional smoked fish supply chain in Bone Regency.

Kajian literatur identifikasi dan pemahaman tentang kontaminasi mikroplastik di biosfer
Mikroplastik merupakan partikel plastik dengan ukuran kurang dari 5 mm yang kini menjadi zat kontaminan yang semakin diperhatikan dalam konteks ekotoksikologi lingkungan akuatik dan juga bagi kesehatan manusia. Walaupun polusi mikroplastik tersebar di biosfer daratan, air, dan udara, lingkungan ini sering kali dilihat sebagai entitas terpisah; meskipun, pada kenyataannya, keduanya saling terkait. Penelitian ini bertujuan untuk meninjau literatur ilmiah yang terkait dengan penelitian mikroplastik di biosfer dan mengidentifikasi kesenjangan dalam penelitian yang dapat membantu menilai prioritas penelitian di masa depan. Artikel ilmiah yang membahas polusi mikroplastik, diterbitkan antara tahun 2014 dan 2024, diidentifikasi dalam basis data Web of Science. Artikel penelitian asli yang tercakup dalam kategori Environmental Sciences, Marine/Freshwater Biology, Toxicology, Multidisciplinary Sciences, Environmental Studies, Oceanography, Limnology, dan Ecology di Web of Science dan lainnya dipilih untuk mengeksplorasi penelitian mikroplastik di laut, estuari, sungai, danau, tanah, dan atmosfer. Artikel yang terkait dengan laut, estuari, sungai, dan danau kemudian diklasifikasikan lebih lanjut berdasarkan (i) keberadaan dan karakterisasi, (ii) penyerapan dan dampak pada organisme, dan (iii) isu perilaku dan transportasi. Hasilnya menunjukkan bahwa sementara penelitian mikroplastik di laut telah menerima perhatian ilmiah yang signifikan, pemahaman terhadap sejauh mana polusi mikroplastik di lingkungan kontinental, seperti sungai, danau, tanah, dan udara, beserta interaksi lingkungannya, masih kurang memadai.

HA PERAN MODAL SOSIAL DALAM PENGAMBILAN KEPUTUSAN PRODUKSI DAN RELASI PRODUKSI PEMBUDIDAYA RUMPUT LAUT DI DESA PUNAGA KABUPATEN TAKALAR
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. Keywords: Social capital, Seaweed, Patron client, Inequality, Seaweed Farmer

Indonesian Blue Economy for Sustainable Fisheries
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

Fish feed is an important factor in aquaculture, where the physical properties of sinking feed affect its efficient use by fish. Waste fish filets have potential as an alternative feed, but farmers have difficulty finding high-quality feed at affordable prices. This study aims to determine the physical properties of feed with the addition of fermented fish filet waste flour (TLFIF). The method used was a completely randomized design (CRD) with 5 treatments and 3 replicates: P0 (control, without TLFIF), P1 (10% TLFIF), P2 (20% TLFIF), P3 (30% TLFIF), and P4 (40% TLFIF). Parameters observed included: appearance test, aroma, texture, durability test, homogeneity test, and feed sinking speed test. Data were analyzed using analysis of variance (ANOVA) and descriptive analysis. The best TLFIF addition research results were found in the 10% treatment (P1), which had a durability of 98.80%, homogeneity of 42.67%, and a sinking speed of 7.15 seconds/20 cm. The feed's appearance is light brown in color, cylindrical in shape, and fairly uniform in size, with a dense, fibrous texture, a slightly rough surface, and a slight fermentation aroma.
Level of Likeness of Sausages Based on Type of Demersal Fish
Processing fish meat as soon as possible is very important to increase its added value. The demand for processed fish products that is currently increasing is fish sausages. This research aims to determine the appropriate type of demersal fish meat as the main ingredient for making sausages based on the level of organoleptic preference. The research method used was experimental with a completely randomized trial design with three treatments. The three treatments are fish meat, pomfret, snapper and grouper meat. The fish sausages obtained from the three treatments were observed for their level of preference for appearance, aroma, texture and taste. The data obtained were analyzed using non-parametric statistics, the Friedman test and the multiple compression test. The Bayes method was used to determine the selected treatment. The results showed that the level of preference for the appearance, aroma, texture and taste of fish sausages was not influenced by the type of demersal fish meat used. Fish sausages made from snapper fish are preferred over sausages made from grouper or pomfret fish. The snapper sausage has a favorite level in the category of appearance, aroma, texture and taste. The average value of appearance favorability is 7.13 with a favorability percentage of 79.3%. The average value of aroma preference level is 6.20 with a percentage preference level of 68.9%. The average value for texture preference level is 7.13 with a percentage preference level of 79.3%. The average value of taste preference level is 6.86 with a percentage preference level of 76.3%.
The Effect of Adding Thyroxine Hormone (T4) to Commercial Feed on The Growth Profile of Pompano (Trachinotus blochii, Lacapede)
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
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
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.
