Abstract

Two species of scad fish (Decapterus russelli and D. macrosoma) is a major catch of purse seine in almost fishing area, its contributed approximately 58%. Production data of scad fish is based on catch data of purse seine which having fishing base in Java (2006-2007). Chlorophyll-a concentration, sea surface temperature and Photosyntetic Available Radiation (PAR) was derived from satellite imagery AQUA MODIS. That data is used to estimate primary productivity with Vertically Generalized Production Model (VGPM). The effect of ENSO (El Niño-Southern Oscillation) to scad fish fisheries also discussed. This research is aimed to get information about the effects of ENSO to primary productivity and abundance of scads in the southern part of Makassar Strait. Results showed scad fish abundance in the waters of the southern Makassar Strait fluctuates according to season, the peak abundance lasted for three months between November to January. Utilization of scad fish as 3th tropic level component showed percentage of utilization is 8,93% in 2006 and 14,59% in 2007. AQUA MODIS image data showed the highest chlorophyll concentrations occurred between February to April each year. While the highest sea surface temperature occurs in November-January period. There are indication that ENSO have indirect effect to chlorophyll-a consentrations and sea surface temperature. Both of them having relations with scad fish abundance in Makassar Strait.

Abstract

Occupational Health and Safety (OHS) in the fishing industry is often overlooked, despite the extremely high potential for work-related accidents. This study aims to analyze the risks during the post-harvest process of shark fins at Tanjung Luar Fishing Port and UD Mamenasae using the Hazard and Operability Study (HAZOP) method. The results indicate that nearly all activities, especially cargo hold unloading, transfer, transport, identification, shark cutting, and fin drying, have a high-risk potential for accidents such as falls/slips, musculoskeletal complaints, cuts, and sunburn. Some processes, including transportation to collectors, storage, sorting, and packaging, carry a moderate risk of concussion or respiratory disorders. Furthermore, all stages present a low risk of bacterial infectious diseases. The primary hazards identified include slippery floors, non-ergonomic work postures, sharp objects, the absence of Personal Protective Equipment (PPE), sun exposure, and a lack of railings. As a mitigative measure, temporary actions such as improved hygiene, provision of PPE, ergonomic improvements, and education are highly recommended to reduce potential hazards and enhance workplace safety.

Abstract

The exponential increase in carbonaceous-based research has prompted the scientific community to apply it to numerous value-added applications. This paper aimed to systematically analyze the comprehensive contributions clusters of publications per year, country, institution, authors, and keywords-wise by using a quantitative review technique called bibliometric analysis. The data was retrieved from the Scopus database to identify the overall scientific trend results with the keyword "carbon dots as a sensor" from 2010 to 2020. The VOSviewer, WordItOut, and Datawrapper are selected as tools for bibliometric analysis and data visualization. In this work, the total citations from the Scopus Core Set and the total citations in the most recent year have only been used for the assessment of highly cited papers. The results showed that after 2014, the number of publications increased significantly with the work related to “carbon dots as sensors.” Thus, comprehensive journals like the Angewandte Chemie - International Edition were the most popular in publishing articles, contributing to almost 6.39% of the research area. The country-wise analysis revealed that China accounted for more than 67.18% of the articles published, followed by the United States and India, comprising 6.24% and 6.13%, respectively. Lastly, keyword cluster analysis revealed five major research hotspots for future discussion. Thus, this analysis provides an important starting point for further studies on research concerning the direction of "carbon dots as a sensor" for positive development in the research area.

Abstract

ABSTRAKPenelitian ini bertujuan menganalisis perkembangan, fokus tematik, dan arah riset terkait penggunaan environmental DNA (eDNA) metabarcoding untuk mendeteksi dan mengidentifikasi spons laut (Porifera). Pendekatan yang digunakan adalah systematic literature review (SLR) berbasis PRISMA dan analisis bibliometrik terhadap artikel terindeks Scopus tahun 2009–2025. Dari 116 publikasi awal, 42 artikel memenuhi kriteria inklusi dan dianalisis lebih lanjut menggunakan VOSviewer untuk mengidentifikasi tren publikasi, pola kolaborasi penulis-negara, serta struktur klaster kata kunci. Hasil menunjukkan peningkatan signifikan publikasi sejak 2017, dengan kontribusi terbesar berasal dari Britania Raya, Spanyol, dan Amerika Serikat. Analisis kata kunci menghasilkan lima klaster utama yang mencerminkan arah riset global, yaitu (1) genetika dan biodiversitas, (2) mikrobioma dan metagenomik, (3) ekologi terumbu karang, (4) invertebrata laut, serta (5) lingkungan ekstrem. Meskipun eDNA metabarcoding terbukti sensitif untuk mendeteksi komunitas spons, tantangan utama yang ditemukan mencakup keterbatasan marker gen yang belum universal serta kelengkapan basis data taksonomi yang masih rendah. Novelty penelitian ini terletak pada penggabungan SLR dan bibliometrik secara khusus pada spons laut, sehingga mampu mengungkap kesenjangan geografis, keterbatasan metodologis, serta menawarkan rekomendasi strategis berupa standardisasi protokol, penguatan basis data referensi lokal, dan perluasan kolaborasi internasional, terutama di wilayah megabiodiversitas seperti Indonesia.Kata Kunci: eDNA, metabarcoding, Porifera, bibliometric, keanekaragaman hayati.ABSTRACTThis study analyzes the development, thematic focus, and research direction of environmental DNA (eDNA) metabarcoding applied to the detection and identification of marine sponges (Porifera). A systematic literature review (SLR) following PRISMA and a bibliometric analysis of Scopus-indexed publications from 2009–2025 were conducted. From an initial 116 records, 42 articles met the inclusion criteria and were analyzed using VOSviewer to identify publication trends, author–country collaborations, and keyword cluster structures. Results show a substantial increase in publications since 2017, with major contributions from the United Kingdom, Spain, and the United States. Keyword analysis revealed five major thematic clusters: (1) genetics and biodiversity, (2) microbiome and metagenomics, (3) coral reef ecology, (4) marine invertebrates, and (5) extreme environments. Although eDNA metabarcoding demonstrates high sensitivity for sponge detection, key challenges include non-universal genetic markers and incomplete taxonomic reference databases. The novelty of this study lies in integrating SLR and bibliometric approaches specifically for marine sponges, allowing the identification of geographic gaps, methodological limitations, and providing strategic recommendations for protocol standardization, the development of local reference databases, and enhanced international collaboration, particularly in megabiodiverse regions such as Indonesia.Keywords: eDNA, metabarcoding, Porifera, bibliometric analysis, biodiversity.
