No full textSea anthills (Hippidae) are a class of crustaceans that live in tidal zones, with sandy substrates and have the potential to be used as an alternative food source. This research was conducted in November 2023 on Tial beach. Specifically, Tial beach is located east of Ambon Island with fine to medium sandy substrates. This research aims to identify the morphological characteristics of Hippidae, as well as analyze their nutritional content. The data collection method used 5 quadrant transects measuring 2 x 2 m with a distance of 8 m in each quadrant. The results showed that there were Hippidae species found, namely Hippa marmorata with a total of 49 individuals/50m2 with a carapace length ranging from 0.8 cm - 4 cm and a body weight of 0.49 gr - 6.58 gr. Morphometric analysis showed a very strong level of relationship between Hippa marmorata and its growth pattern is positive allometric. The proximate content shows that Hippa marmorata contains protein and fat to support its use as a functional food. These data provide important insights into the morphometric aspects and nutritional value of Hippa marmorata. The results support the use of Hippa marmorata as a low-fat and ecologically potent seafood source.Sea anthills (Hippidae) are a class of crustaceans that live in tidal zones, with sandy substrates and have the potential to be used as an alternative food source.

Kajian literatur identifikasi dan pemahaman tentang kontaminasi mikroplastik di biosfer
Full text linkMicroplastics 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.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
Analisis Persepsi Dampak Limbah Tambak Udang Terhadap Pendapatan Nelayan Skala Kecil Di Kecamatan Mallusetasi, Kabupaten Barru
Full text linkSmall-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.Secara global, perikanan skala kecil merupakan sektor penting dari ekonomi biru dan memiliki peran penting bagi masyarakat dalam memenuhi kebutuhan pokok.

Physical Test of Sinking Feed Made from Fermented Fish Filet Waste Meal
Full text linkFish 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\u27s 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

Full text linkThe 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\u27s 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
Development Center of Minapolitan Area in Wajo District
Full text linkRegional 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
A Review on Chicken Feather Flour Potential for Fish Feed
Full text linkThe 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
