Abstract

Traditional fish smoking methods often raise significant concerns regarding product safety, quality inconsistency, and environmental pollution. This study aimed to evaluate a modified Efhilink smoking cabinet designed to address these issues by utilizing agricultural waste, specifically corn cobs and coconut shells, as bio-smoke sources for producing high-quality, safe smoked fish compliant with the Indonesian National Standard (SNI 2725:2013). Three fish species (mackerel tuna, Euthynnus affinis; flying fish, Cypselurus spp.; and ray, Dasyatis spp.) were processed using the modified cabinet and a traditional cabinet (control) and subsequently analyzed for sensory properties, proximate composition, histamine, TVB-N, pH, total phenolic content, and various contaminants (microbiological, heavy metals, chemical residues, and polycyclic aromatic hydrocarbons (PAH4)). The results demonstrated that all smoked fish samples from the modified cabinet met all critical parameters of the national standard. Coconut shell smoke generally yielded superior products, characterized by higher acceptability in aroma and taste, a greater infusion of phenolic compounds (up to 0.334 mg/kg), and significantly lower levels of PAH4 contaminants compared to the traditional control. All samples from the modified cabinet exhibited histamine levels well below the 100 mg/kg safety limit (12.36–19.37 mg/kg), total plate counts within the permissible range (10 to 3.6x10? CFU/g), and a complete absence of detectable pathogens (E. coli, Salmonella spp., S. aureus, V. cholerae) or hazardous chemical residues (chloramphenicol, malachite green, nitrofuran); heavy metal contaminants were also found at levels far below the maximum allowable limits. The modified cabinet significantly outperformed the traditional method in reducing PAH4 contamination. The technology not only enhances food safety but also promotes sustainable practices by converting agricultural waste into value-added products. In conclusion, the modified Efhilink cabinet, using either corn cob or coconut shell bio-smoke, effectively produces safe, high-quality smoked fish that complies with stringent food safety standards, with coconut shells demonstrating superior performance as a smoke source by enhancing sensory attributes and bioactive compound content while minimizing hazardous contaminants.

Abstract

Marine plastic waste in Palang Village, Tuban Regency, has caused serious environmental problems, such as water pollution, declining fish catches, and health disturbances due to microplastics. This community service initiative aims to address these issues through the implementation of RECYFUEL pyrolysis technology, which converts plastic waste into alternative energy (diesel) while empowering the Putera Bahari Youth Group. Implementation methods include socialization, technology application training, mentoring and evaluation, and program sustainability measures. The results show an increase in the partners' empowerment level in Management Aspects (100% of partners mastered waste management and financial reporting), Production Aspects (90% of partners were able to independently produce diesel), and Marketing Aspects (90% of partners were able to market diesel products to local fishermen). A total of 50% of plastic waste was successfully processed into diesel, with a conversion rate of 1 kg of plastic yielding 300–400 ml of diesel, along with the creation of a new profitable business opportunity. This program not only reduces environmental pollution but also enhances the economic income of the community. Thus, RECYFUEL technology proves to be an effective and sustainable solution for plastic waste management and the empowerment of coastal communities

Abstract

Regular monitoring of microplastics contamination in marine biota have been concerned in the world, since its tiny size can be swallowed direct or indirectly and lead health problems. Tuban waters is the one of Indonesia's coastal and marine fisheries areas with high risk of microplastic pollution due to their highly anthropogenic activities. We investigated the microplastic in the digestive tracts of pelagic and demersal fishes in Tuban sea waters.  Microplastic in fish sample guts were observed under microscope and the type of polymer were examined using FT-IR. This study reveals that number of microplastic in digestive tract of pelagic fishes were higher than demersal fishes. The dominant form was fiber (62%) with black color and dominant size ranging from 100-500 um (72%). The types of polymers found were polyethylene and polyamide.

Abstract

Graphical Abstract   Highlight Research DNA Barcoding and Species Analyzed: Tissue samples from 11 individuals across five shark species and two ray species were analyzed using DNA barcoding. The species include Sphyrna lewini, Carcharhinus sealei, Stegostoma fasciatum, Galeocerdo cuvier, Carcharhinus falciformis, Rhynchobatus australiae, and Rhina ancylostoma. Genetic Similarity and Divergence: Results showed high genetic similarity within species, but some divergence was observed between different populations, indicating potential evolutionary or geographic separations. Phylogenetic Relationships: The phylogenetic analysis revealed seven distinct clades, providing insight into the evolutionary relationships of these species. Conservation Implications: Several species identified in the study are protected, such as lewini, G. cuvier, and C. falciformis. The study underscores the importance of incorporating genetic diversity data into conservation strategies to protect these ecologically vital species in Indonesia.     Abstract Sharks and rays, as apex predators or mesopredators, help maintain marine biodiversity and ecosystem balance. Their ecological and economic value underscores the need for conservation, as they face threats from overfishing, habitat loss, and climate change, with many classified as vulnerable or endangered by the IUCN. This study investigates the genetic diversity and phylogenetic relationships of sharks and rays in Bawean and Masalembu Waters, East Java, using morphological identification and DNA barcoding. The specimens were obtained from fishermen operating in Bawean and Masalembu Waters     . A total of 11 samples were analyzed from five shark species: Sphyrna lewini, Carcharhinus sealei, Stegostoma fasciatum, Galeocerdo cuvier, and Carcharhinus falciformis, and two ray species: Rhynchobatus australiae and Rhina ancylostoma. Results showed high genetic similarity within species, with some divergence observed between samples from the Bawean and Masalembu regions. For instance, populations of Sphyrna lewini from the two regions exhibited slight mitochondrial DNA sequence variations, indicating possible adaptations to local environmental conditions. Similarly, genetic differences in Rhynchobatus australiae suggest limited gene flow between populations, likely influenced by geographical barriers or habitat preferences. Phylogenetic analysis revealed seven distinct clades, highlighting evolutionary relationships such as the close grouping of S. lewini and G. cuvier, which suggests recent divergence. Several species identified, including S. lewini, G. cuvier, and C. falciformis, are protected, underscoring the need for stricter conservation and monitoring efforts to safeguard shark and ray populations. This study highlights the urgency of integrating genetic diversity into conservation strategies to ensure the long-term survival of these vital species.

Abstract

Determination of the datum chart using the tide component can be used to determine the depth of the harbour basin. TPI Palang's harbour basin is often used as a place for mooring fishing boats, but it often happens that the ships get stuck before entering the haarbour basin. The type of fishing ship at the TPI Palang harbour basin is a payang boat with a draft depth of 2 m. The depth of the harbour basin measurement results in July 2017 was 8 m, while based on the bathymetric map is 12 m. Palang waters, in Tuban Regency is located in the North Sea of East Java, which is open water type, therefore the determination of the depth of the harbour basin is based on the state of the water, is 1.2 x ship draft, which is 2.4 m. The least square and the admiralty method were used to compare the best method in calculating the tidal component. Researchers used tidal data for August 2016- July 2017 obtained from BIG. The tidal type of the Palang waters is diurnal, with an F value for admiralty treatment of 5,160 with least square processing of 5,167. The correlation coefficient of the tidal component with admiralty processing occurs in K1-MS4 of 0.792, while the least square occurs in K1-M4 of 1.6. The result of the calculation of the tidal component of the least square is used to determine the value of the datum chart. The IHO (International Hydrographic Organization) datum chart is used as a basic reference for calculating the depth of the TPI Palang harbour basin. The results show that the required depth of Palang waters in the existing condition (8 m) still requires dredging between 0.033 - 1.071 m. However, to meet the standard of the harbour basin, the required depth is 13,071 m (from LWS) to 13,557 m (from LLWS) which means that the dredging of the harbour basin is about ± 4 m.

Abstract

Drought is a recurring hydrometeorological hazard in Indonesia, particularly affecting regions with high rainfall variability and rainfed agriculture dependence. This study analyzes spatial-temporal drought patterns in Jatirogo Subdistrict, Tuban Regency, East Java (2020-2025) using the Normalized Difference Drought Index (NDDI) from Sentinel-2 imagery. The methodology involved image preprocessing, NDVI and NDWI calculation, NDDI derivation, and GIS-based drought classification. Results show strong seasonal patterns with peak severity during August-October, where moderate to severe drought dominated 65-80% of the area annually. The most severe conditions occurred in 2023-2024, with NDDI values exceeding 1.0. Villages including Kebonharjo, Sugihan, Demit, Bader, and Sekaran were identified as highly vulnerable. NDDI-based mapping revealed significant correlations with sectoral impacts: severe drought periods (NDDI > 0.8) corresponded with 40-60% crop yield reductions in rainfed paddies, increased irrigation demand, critical groundwater depletion, and elevated food security vulnerabilities among smallholder farmers. This study demonstrates that Sentinel-2 NDDI integration with GIS effectively supports village-level drought monitoring and provides essential spatial information for targeted mitigation strategies, including water resource management, adaptive agricultural planning, and early warning systems.
