Tiku Beach in Tanjung Mutiara District, Agam Regency, West Sumatra is a 12.77 km coastal area experiencing continuous shoreline changes due to abrasion and accretion. This study aims to identify and map shoreline changes and calculate the area of abrasion and accretion in 2014, 2019, and 2024 using the Modified Normalized Difference Water Index (MNDWI) method based on Landsat 8 OLI satellite imagery. The MNDWI method utilizes the reflectance difference in the Green band (Band 3) and SWIR band (Band 6) to automatically separate the land-water boundary. Shoreline change analysis was performed using Net Shoreline Movement (NSM) and End Point Rate (EPR) methods through ArcGIS 10.8 software with the Digital Shoreline Analysis System (DSAS) extension. Analysis of 336 transects shows that accretion is more dominant than abrasion along Tiku Beach. The largest accretion was recorded at transect 230 with an NSM value of 71.3 m and an EPR rate of 7.12 m/year, while extreme abrasion occurred at transect 249 with an NSM value of -121.67 m and an EPR rate of -12.15 m/year. The evolution of the shoreline shows that in 2014 the coastline was still relatively stable, then in 2019 mild abrasion occurred in the west along with accretion in the east, and by 2024 this pattern became more pronounced. The results of this study are expected to serve as a scientific basis for decision-making in coastal disaster mitigation planning and sustainable coastal management in Agam Regency.

Mangrove forests play an important role in maintaining the stability of coastal ecosystems, reducing coastal abrasion, and supporting the socio-economic life of coastal communities. However, the sustainability of the mangrove ecosystem in Kayu Ara Permai Village, Siak Regency, faces various threats originating from natural factors and human activities. This study aims to evaluate the policy of mangrove forest protection and preservation in Kayu Ara Permai Village and identify obstacles in its implementation. This research used a descriptive qualitative method with data collection techniques through observation, interviews, and documentation. The results showed that the implementation of Village Regulation Number 07 of 2018 succeeded in reducing illegal logging activities and increasing public awareness regarding mangrove conservation. Policy evaluation was analyzed using indicators of effectiveness, efficiency, adequacy, equity, responsiveness, and accuracy. The findings indicate that the policy has been fairly effective in controlling illegal exploitation, but has not been optimal in addressing coastal abrasion and providing rehabilitation support facilities. The main obstacles include increasing coastal abrasion, limited wave-breaking equipment, lack of operational patrol facilities, and limited institutional support. Therefore, stronger collaboration between the village government, local communities, and regional government is needed to improve the sustainability of mangrove protection and preservation policies.

This study analyzes the strategy of the Community Monitoring Group (Pokmaswas) in developing mangrove forests in Pelambung Village, Tanjung Balai Karimun, Riau Islands. This study aims to explore Pokmaswas management patterns and their impacts on local communities and coastal ecosystems. Mangrove forests play a crucial role in maintaining ecosystem balance, protecting coasts from abrasion, flooding, and storms, and supporting the biodiversity of fish, shrimp, and crabs. In Indonesia, mangrove area has decreased drastically from 5.2 million hectares in 1982 to around 2.5 million hectares due to land conversion, logging, and pollution. In Pelambung Village, Pokmaswas, established in 2023, began rehabilitation by planting 5,000 mangrove seedlings such as Rhizophora (mangrove), Avicennia (api-api), and Sonneratia. This qualitative, descriptive study, using observation, local community interviews, and documentation techniques, was conducted from July to August 2024. The Community Development Group (Pokmaswas) is active in nursery, harvesting, maintenance, monitoring, and ecotourism development, generating economic benefits (job creation, mangrove coffee MSMEs and miniature canoes), ecological benefits (protection from abrasion, increased fisherman's catch), and biological benefits (marine biota habitat). Challenges include limited funding, pest attacks, and integration with regional development.    

In general, infrastructure development requires materials from nature and one of them is natural coarse aggregate of crushed stone. The rapid development of infrastructure in Indonesia has resulted in the depletion of the natural coarse aggregate. Therefore, other efforts are needed in terms of using coarse aggregate as a construction material. So in this study the aim is to make artificial coarse aggregate made from fly ash. The results showed that this artificial coarse aggregate met the requirements of the General Specifications of Bina Marga 2010 rev 3 as a construction material, namely for an abrasion value of 40% and water absorption of 3%. In this study, 5 types of comparisons were carried out, namely, 70:30%, 60:40%, 50:50%, 40:60%, 30:70 and for the type of composition comparison 70:30% (70% fly ash:30% cement). ) the abrasion value is still below 40%, and the amount of water absorption is below 3% so that this artificial coarse aggregate still meets the standard specifications of General Highways 2010 rev 3. Based on the price comparison that has been made between artificial coarse aggregate and natural coarse aggregate of crushed stone , shows a price disparity of Rp. 35,779 - Rp. 58,779. Thus, this artificial coarse aggregate is one solution that can be developed to reduce the environmental impact due to the presence of fly ash which is quite abundant in Indonesia.

Holtekamp Beach is a coastal area in Jayapura City that is very prone to abrasion due to sea waves because it is located directly opposite the Pacific Ocean.

The research aims to analyze the impact of abrasion on the Holtekamp coastal area using survey and interview methods. Furthermore, data analysis is carried out by utilizing SWOT Analysis. This research was conducted from May to June 2025. The results showed that there are 4 (four) priority strategies that can be used as a basis for developing a strategy for Abrasion Disaster Risk Management Strategy in the Holtekamp Coastal Area of Jayapura City, namely; a) Increasing cooperation & coordination between stakeholders, namely the community and local government in achieving abrasion disaster management programs in the Holtekamp Coastal Area of Jayapura City; b) Optimizing supervision of development development/tourist lodges in the coastal area of Holtekamp Beach; c) Community participation is needed to maintain infrastructure that has been built and increase their awareness of environmental issues.d) Construction of wave breakers that function to reduce waves.

This study aims to analyze how internal strategies and external challenges can influence the achievement of Regional Original Revenue targets at the Laboratory Technical Implementation Unit (UPTD) of the Public Works and Public Housing Agency (Dinas Pekerjaan Umum dan Perumahan Rakyat) of Cilacap Regency. The research object is the performance of the Laboratory Technical Implementation Unit (UPTD), a technical unit providing construction material testing services, which directly contributes to Regional Original Revenue in Cilacap Regency. The qualitative approach employed a case study method, and data collection techniques included interviews, observation, and documentation. The sample in this study was obtained purposively. The results indicate that internal strategies focused on superior testing methods such as core drilling, abrasion, and concrete compressive strength have been conducted. However, limited equipment, human resources, and the lack of accreditation are major obstacles. On the other hand, external challenges include the lack of updated Regional Regulation tariff regulations, the absence of formal obligations for the use of laboratory services for regional budget projects, and a saturated local market. These findings provide important implications for the Laboratory Technical Implementation Unit (UPTD) in emphasizing policy revisions, increasing internal capacity, and strengthening inter-agency coordination to increase Regional Original Revenue realization.

Pedada leaves (Sonneratia caseolaris), a type of mangrove plant that grows in tropical and subtropical coastal areas, have high ecological and pharmacological value. In addition to functioning as coastal protection from abrasion and seawater intrusion, this plant is also known to contain various secondary metabolite compounds such as flavonoids, tannins, saponins, and alkaloids. These compounds have been widely reported to have important biological activities, one of which is as an antimicrobial agent. This study aims to identify the effectiveness of pedada leaf ethanol extract in inhibiting the growth of pathogenic microorganisms, especially bacteria that cause infections. The extraction process was carried out using 96% ethanol solvent through the maceration method, namely soaking the material in the solvent for a certain time to optimally obtain active compounds. The obtained extract was then tested for its antimicrobial activity using the disc diffusion method against test bacteria, both Gram-positive and Gram-negative. The inhibition zone formed around the disc was measured as an indicator of the antibacterial effectiveness of the extract. The results showed that pedada leaf extract was able to produce inhibition zones with varying diameters depending on the concentration used. The higher the extract concentration, the larger the diameter of the inhibition zone formed. This indicates a positive relationship between extract concentration and its antibacterial strength. This activity is believed to originate from the ability of compounds such as flavonoids and tannins to damage bacterial cell walls or disrupt microbial metabolic processes. This study provides initial evidence that pedada leaves have potential as an environmentally friendly and sustainable source of natural antibacterials. This potential is highly relevant in efforts to develop alternative antibacterial materials based on local plants, especially amidst increasing bacterial resistance to synthetic antibiotics.

A traffic accident is an unexpected road event involving a vehicle with or without other road users resulting in human casualties and/or property loss. This research is a retrospective descriptive using secondary data from visum et repertum results of patients. The research sample was analyzed using a univariate approach to determine the distribution of age, gender, occupation, location of injuries, type of injuries, number of injuries based on the type of injury, the status of road users, and how patients arrive. The results of the study obtained as many as 2984 victims alive and 210 victims died. The age group of 15–29 years is the most (49.3% for living victims and 39% for dead victims), with a male predominance. The head and neck were the most common locations for injuries (73.1% of living victims and 90.5% of deaths). Abrasions were the most type of wound (82.4% of living victims and 81.4% of deaths). In the group of road users, 59.2% were motorbike riders and 71.1% came to the third referral hospital in Padang by being referred from another hospital. The living and dead victims due to traffic accidents based on age, gender, location of injuries, and types of injuries are in the same group.

Coastal areas are transitional areas between land and marine ecosystems that are very vulnerable to natural disasters, one of which is abrasion. Coastal abrasion is the process of erosion of coastal areas caused by wave activity, ocean currents, and human activities such as infrastructure development and sand mining. Ciberi Beach (Tanjung Ciberi) located in Enggros Village, Abepura District, Jayapura City, is one of the coastal areas that experiences continuous abrasion. Its strategic location and direct facing the Pacific Ocean makes this area very vulnerable to coastal erosion. Based on the author's experience while conducting Field Work Practices at the Papua River Basin Center (BWS Papua), it is known that abrasion has caused damage to public facilities and significant coastline decline since 2019 (Cepos, 2024). Strong suspicions arose from the community based on the results of interviews conducted that the construction of the Youtefa Bridge contributed to the acceleration of abrasion. Previous research also showed that the rate of abrasion in the Yos Sudarso Bay area, including Ciberi Beach, reached 0.89 meters per year. Therefore, this study aims to analyze the level of damage to Ciberi Beach due to abrasion during the period 2014–2024, and to provide recommendations for handling to reduce the impact of damage in the coastal area.

The sea fence in Tangerang Regency, Banten, has become a complex issue involving violations of spatial law, environmental impacts, and the rights of coastal communities. This research analyzes the social and environmental impacts of the case and examines the protection and restoration of victims' rights based on a greenvictimology perspective. Using an empirical juridical approach, data collection was conducted through interviews with fishermen and legal aid organizations, as well as secondary data from legal literature. The results showed that sea fences disrupt fishermen's activities, damage marine ecosystems, and violate regional spatial regulations. Ecological impacts include changes in ocean currents, decreased water quality, disruption of fish migration, damage to coral reefs, and coastal abrasion. Protection and restoration of victims' rights in the Pagar Laut case to date have not been fully fulfilled and realized by the responsible parties. This can be seen from the absence of concrete policies and concrete actions in the form of providing compensation or compensation to fishermen who are directly affected by the installation of the Sea Fence which hampers their access and space for fishing activities. In addition, efforts to restore the marine environment have also not been carried out optimally, especially in terms of dismantling sea fences that have not been carried out thoroughly and assistance programs from the Ministry of Maritime Affairs and Fisheries have not been implemented.

The mangrove ecosystem is an ecosystem that has a very high ecological value.

Minor wounds, such as abrasions, scratches, or small cuts, are commonly experienced by teenagers, especially in school environments. However, improper treatment of minor wounds can lead to infections and more severe complications. This study aims to raise awareness and educate students at SMP Negeri 1 Kairatu on the proper management of minor wounds. The research employs a descriptive approach with an interactive educational method involving presentations, discussions, and live demonstrations. Respondents in this study were students from grades 7 to 9. The results indicated that prior to the socialization, most students had inadequate knowledge regarding proper wound care, often resorting to inappropriate methods (e.g., using toothpaste or oil). After the educational intervention, there was an 85% increase in students’ understanding of proper wound management, such as cleaning wounds with clean water, applying antiseptics, and covering wounds with sterile bandages. The socialization program also successfully raised awareness among students about the importance of wound hygiene to prevent infections. Thus, this initiative proved effective in enhancing teenagers' knowledge of proper wound care practices.

This research aims to develop the potential of ecotourism based on local wisdom in the mangrove forest area of Tapak, Semarang City. The methods used include field observation, interviews with local stakeholders, and qualitative data analysis. The results show that local wisdom plays an important role in managing the mangrove ecosystem and improving community welfare. Traditional practices applied by the local community are effective in maintaining environmental balance and addressing threats of abrasion and pollution. The Tapak mangrove area faces significant challenges, including coastal erosion and industrial waste pollution, which threaten the ecosystem's sustainability. However, the local community has developed various initiatives based on local wisdom for mitigation and conservation. Collective mangrove planting, the use of natural materials in pond management, and the implementation of zoning systems are some practices that have shown positive results. The development of ecotourism in this area not only has the potential to increase local income but also to strengthen environmental awareness among the community and visitors. Recommendations from this study include enhancing community capacity in ecotourism management, strengthening zoning systems, and promoting ecotourism based on local wisdom. Training and empowering the community in aspects of tourism guidance and sustainable resource management are key to ensuring the long-term success of this ecotourism. Therefore, sustainable and community-based ecotourism management strategies need to be continuously developed and supported by various parties to preserve the mangrove ecosystem and improve the welfare of the local community.  

The coastal area in Aeng Batu-Batu Village, Galesong, Takalar Regency is one of the areas whose lives depend on marine products, especially on seaweed cultivation as their main livelihood. However, due to the sea mining activities that began in the area since 2017 to meet the needs of infrastructure projects on the Center Point of Indonesia (CPI) reclamation island, it has had a significant impact on the social life of the local community, a change in income that has decreased from seaweed cultivation which has finally made fishermen switch to looking for other marine biota such as crabs and squid. In the context of social dynamics that occur as a result of mining, it has made changes in the daily activities of the local community, especially in the search for income. In this case, the solidarity of the local community is also an important factor in changing habits that occur after sand mining occurs. Sand mining also triggers coastal abrasion which causes houses in coastal areas to be exposed to abrasion. This research uses qualitative methods that focus on interview techniques, observation and literature review which are used to analyze the effects of sand mining on the coastal communities of Aeng Batu-Batu Village. The results of this study show that coastal sand mining has brought changes to the social dynamics and interaction patterns that exist in the community, especially in the management of marine resources and their place of residence. These results are expected to be material for further attention regarding coastal environmental management policies related to the utilization of natural resources, especially for reclamation needs in order to prevent negative impacts that arise in coastal communities.

This article examines the management of marine tourism in Lanjukang Island, a tourist destination located in the Spermonde Islands, Makassar City, South Sulawesi, with a focus on the role of maritime diplomacy in increasing tourism potential while preserving marine resources. This research uses a qualitative approach with literature study methods and interviews with relevant parties, such as local governments and local communities. Lanjukang Island, with its beautiful underwater nature and beaches, faces challenges in the form of coral reef damage due to destructive fishing practices and coastal abrasion processes. Nevertheless, Lanjukang Island remains an attractive tourist destination for domestic and foreign tourists. The Makassar City Government plays an active role in promoting marine tourism through international collaboration, one of which is through the Makassar International Eight Festival and Forum (F8) event. Maritime diplomacy, which emphasizes international cooperation in marine resource management and tourism, plays a key role in facilitating sustainable tourism development on Lanjukang Island. The research found that while there is great potential in the marine tourism sector, more integrated and sustainable management is needed to support the local economy and the preservation of the marine environment. Collaboration between government, community and international partners is essential to achieve a balance between tourism development and nature conservation.

The Naval Academy is one of the state educational institutions that also contributes to the preservation of mangrove forests in Indonesia, especially in the Surabaya area and its surroundings in order to maintain the coastal ecosystem and prevent abrasion. In addition, this mangrove forest can also be used as a training facility for cadets, especially Marine Corps Cadets, in order to prepare Marine Corps Cadets to become a platoon commander, and can train their combat instincts and support the main task of the Naval Academy in producing responsive, agile and agile young officers. One of the efforts to utilize the mangrove forest area is to use it as a training facility called the Swamp Combat Laboratory which aims to improve the combat instincts of Marine Corps Cadets. This is in accordance with the many fields of assignment that the Marine Corps often faces, which are special fields such as swamps, seas, rivers and beaches, where in carrying out assignment operations in these special fields requires instincts and combat abilities, both individual and group, that are professional and trained. With the existence of these training facilities, it can be useful in improving the combat instincts of Marine Corps Cadets and be ready to face various assignments throughout the territory of the Republic of Indonesia.
