The need for Sharia insurance products in the Muslim community continues to significantly increase. Sharia insurance offers sustainability in overcoming the risk of economic loss based on the principles of Islamic law. In addition, Sharia insurance can be a sustainable solution in providing risk management funds. This study aimed to analyze the development and sustainability of Islamic insurance as an alternative form of risk management, as well as its sustainability in the future. The general review is still in the form of the products offered and operational system models in the Sharia insurance industry. The systematic literature review method was used to obtain a visualization and general description of Islamic insurance, employing 774 data articles from 2010 to 2022. From the results of the analysis, it was found that research discussing Islamic insurance has demonstrated significant developments every year. Mitigating risks by offering the principles of Islamic law represents added value for the Islamic insurance industry. In addition, five models of Sharia insurance systems have been introduced and used; namely, the Mudharabah model, the modified Mudharabah model, the Wakalah model, the hybrid model, and the Waqf model. However, the products offered in Sharia insurance are not too numerous and are still focused on individual risk. Based on these results, Sharia insurance will undergo development in the future in terms of both the products offered and risk management. Of course, it can also lead to a transition to the development of sustainable Sharia insurance.

Purpose: This study aims to determine the perceptions of Muslim tourists interested in visiting halal West Java post Covid-19 pandemic has ended. Theoretical framework: West Java is a region of Indonesia that has the potential to become the cornerstone of Indonesia's halal tourism industry so that it can increase its income. However, the government and the community have yet to find solutions to issues with tourism management, particularly in promoting tourism to a larger community. Design/methodology/approach: The non-probability sampling technique used in the quantitative research method yields a sample of 260 respondents. The hypothesis is tested for significance utilizing Path and the Partial Least Square (PLS) analyses of Structural Equation Modelling (SEM). Findings: The result shows that halal tourism and destination image influence visiting intentions of Muslim tourists in West Java tourist destinations, and halal tourism indirectly influences visiting intentions through destination image as an intervening variable in West Java tourist destinations. Research, Practical & Social implications: This research contributes by examining Muslim tourists' behaviour patterns when visiting destinations in West Java. These findings' academic and managerial implications help design halal tourism marketing strategies in West Java, Indonesia. Originality/value: This study is the first conducted tourism interest on Halal tourism in West Java, Indonesia using SEM.

Despite growing global concerns, there has been limited research on the characterization and distribution of microplastics in the Indonesian Throughflow (ITF) pathways, such as the Flores Sea. The Flores Sea is a component of the Indian–Pacific Current, a significant ocean current system that links the Pacific and Indian oceans and has the capacity to carry pollution over large marine ecosystems, making this research extremely important. Understanding the microplastic pollution in this area informs local environmental management. It provides insights into how these currents may distribute microplastics (MPs) across regional and global scales, impacting marine life and human health far beyond the immediate area. To respond to these concerns, this research aims to determine the characterization and distribution of MPs at six research sites in the Flores Sea that are precisely located within the ITF. This work exhibits an extensive dataset focusing on the occurrence, attributes, and dispersion of microplastics in the Flores Sea. The water sampling was carried out during a Jala Citra 3 by the Indonesian Navy from April to May 2023. Sea surface water samples were collected using a Neuston net, while sediment samples were taken from three stations at the shallowest depth using the Ekman Grab sampler. Additionally, abundance, size, shape, and color analyses were conducted using a light microscope, and microplastic types were identified through Raman spectroscopy. The results indicated that the Flores Sea waters and sediment are polluted with microplastics, with relative abundances ranging from 0.75 ± 0.49 to 2.13 ± 0.25 items/l samples. The most dominant shapes identified were filament (77.45%) and fragment (13.40%), with sizes varying between surface water 4.70 to 3799.25 μm and seabed from 67.20 mm to 2176.87 mm, while black (30.07%) and blue (24.51%) were reported as the common MPs colors. The identified polymers include PET and PE. This study confirms visual evidence of microplastics in the open waters of eastern Indonesia. While it may not fully capture the wide range of temporal variations, it establishes initial microplastic presence and dispersion levels. Given that the ITF influences both the Pacific and Indian Oceans, this research contributes to the global understanding of microplastic distribution across ocean basins, underscoring the need for coordinated international efforts to address marine pollution.

Gill net is one of the fishing gear used by Jatigede Reservoir fisherman. The purpose of this research is to analyzed the feasibility of fish catching business with gill net in Jatigede Reservoir. This research was conducted by used data collection method (observation, questioner, literature study) and method of data analysis (feasibility business analysis). The benefits of this research is expected to be informations and references for the research who will expand a fishing business with gill net at Jatigede Reservoir. The result of feasibility of fish catching business with gill net at Jatigede Reservoir is profit value Rp. 70.890.000, Break Event Point price and production (all species of fish) Rp. 4.154/kg and 2.136kg in a year, Benefit Cost Ratio 3,37, Payback Period 2 months and Net Present Value >1 Rp. 52.820.243, the fish catching business using gill net at Jatigede Reservoir is feasible to be developed.

Bacterial infections in aquatic organisms pose a significant threat to shrimp aquaculture, often leading to production losses. In Pangandaran Regency, early shrimp harvesting is frequently practiced as a response to outbreaks. Previous studies have documented Vibrio and non‐Vibrio bacteria in pond water and sediments at five stations, but infections in shrimp tissues remain less explored. This study aimed to identify pathogenic Vibrio species in vannamei shrimp ( Litopenaeus vannamei ) and wild black tiger shrimp ( Penaeus monodon ), examine toxin genes, and quantify bacterial abundance. Samples were collected from five stations and analyzed using culture media, Gram staining and Polymerase Chain Reaction (PCR). Vibrio parahaemolyticus and Vibrio alginolyticus were detected at Stations 1 and 5, whereas only V. alginolyticus appeared at Stations 2, 3 and 4. Station 1 showed the highest Vibrio abundance (1.3767 × 10 ⁶ CFU/g), while Station 3 recorded the lowest (0.009 × 10 ⁶ CFU/g), with significant differences ( p < 0.05). Non‐Vibrio bacteria dominated most stations, except at Station 1 where Vibrio species were predominant. Toxin gene analysis revealed toxR in some isolates, while tdh, trh, pirA and pirB were absent. These findings emphasize the importance of bacterial and genetic monitoring to improve disease surveillance and support sustainable shrimp aquaculture.
