Abstract

Coral reef ecosystems have an important role in maintaining the balance of the marine environment, providing habitat for various ecosystems, and supporting the existence of coastal and marine resources. However, coral is also vulnerable to being threatened by various diseases and health disruption which can cause a decline in its quality and sustainability. This research aims to identify types of diseases and coral health disruption, forms of coral growth infected with diseases and disruption, and analyze the prevalence of coral diseases in Pomalaa waters. Sampling was carried out at 4 observation points. The research used a survey method and a belt transect method, measuring 5 m x 50 m to identify coral diseases and health problems. The research results found 6 types of coral disease, namely Black Band Disease (BBD), White Syndromes (WS), Yellow Band Disease (YBD), Pink Plotch (PP), Ulcerative White Spots (UWS), and Red Band Disease (RBS). Coral health disruption are generally caused by coral bleaching, Crown of Thorns Starfish, Growth Anomalies, Pigmentation Response, and Sediment Damage. The decline in the quality of the aquatic environment plays a major role in the emergence of various diseases and disruption of coral health, which have an impact on physiological disturbances for coral biota. Meanwhile, the coral growth forms (lifeforms) that are infected are Acropora Branching, Acropora encrusting, and Coral Massive. The highest prevalence rate of coral disease was at station 1, while the lowest was at station 4. The high prevalence rate of corals was the result of a combination of various natural and anthropogenic factors. The low level of coral prevalence at station 4 is possible because this side is a windward area that is exposed to currents at all times, thus helping corals to clean sediment attached to the surface which may carry bacteria that cause disease and coral health disruption. Global warming, pollution, destructive fishing practices, and invasive species are some of the main causes that increase corals' vulnerability to disease and health disorders.

Abstract

Bengkulu Province, located on the west coast of Sumatra Island and facing directly onto the Indian Ocean, causes sea waves in Bengkulu Waters to be directly influenced by its geographical conditions. Sea waves in Bengkulu Waters vary due to the influence of monsoon winds and global climate. Seasonal variations in significant wave height (SWH) obtained from altimetry satellite imagery in five regions representing Bengkulu, namely Mukomuko Waters, North Bengkulu, Bengkulu City, Seluma, and Kaur can be used to monitor sea waves. The coordinates of the five regions representing Bengkulu Waters are as follows: Mukomuko is located at 2°40'20.82" S, 100°38'47.12" E; North Bengkulu at 3°20'6.55" S, 101°4'59.68" E; Bengkulu City is located at 4°0'7.57" S, 101°31'49.10" E; Seluma is located at 4°20'0.00"S, 102° 0'0.00"E; and Kaur is located at 5°0'59.65"S, 102°49'24.50"E. The data used for five years (2018-2022) is in the form of an average daily SWH every 3 hours and is processed using Panoply software to display the distribution of SWH and time series for each of the five regions in Bengkulu Waters. The results of the study show that the highest sea waves occurred in Kaur Waters, reaching 3.9 meters in August 2022 with an average wave height of 1.73 meters. Meanwhile, the lowest sea wave height occurred in Mukomuko Waters which reached 2.7 meters in January and February 2022, with an average wave height of 0.3 meters. Sea wave height in Mukomuko Waters, North Bengkulu Waters, Bengkulu City Waters, Seluma Waters, and Kaur Waters showed an increasing trend over the past five years. The relationship between significant wave height and season shows a consistent pattern.

Abstract

The use of mangrove fruit to create economic benefit for the community is anticipated to bolster conservation efforts for the mangrove environment. In Mandar Banyuwangi Village, one application of mangrove fruit is its conversion into flour. This study aimed to examine the proximate composition of Rhizophora mucronata mangrove flour and evaluate the profitability of processing this flour into pastries. The analysis conducted encompasses the proximate content test (including protein, fat, water, ash, and carbs) and a profit analysis that factors in the cost of goods sold (COGS). Mangrove flour manufactured by Poklahsar “Mina UPA Karya” is derived from the fruit of Rhizophora mucronata. The processing method necessitated seven days to manufacture mangrove flour. The proximate composition of mangrove flour, as per SNI criteria, includes water and carbohydrate content, although protein, fat, and ash content are marginally over or below SNI specifications.  Mangrove flour is utilized in a variety of desserts, including nastar, kastengel, cookies, almond chocolate, roses, jam sumprit, chocolate sumprit, peanut cake, and krispi brownies. Products made using processed mangrove flour in pastries yield a profit margin of 9.16% of the cost of goods sold (COGS). The R/C, BEPs, BEPq, profit, and profitability ratio of the mangrove flour processing business indicate profitability, since they go over the minimum requirements of profitability criteria.

Abstract

Rivers play a crucial role as aquatic ecosystems within the hydrological cycle, serving as vital areas for environmental water absorption. Their conditions are intricately shaped by both human activities and the inherent characteristics of their surrounding environments. Among these rivers, the Bone River stands as a pivotal hub of community life in Gorontalo, yet it faces significant vulnerability to pollution. This research endeavors to assess the water quality of the Bone River utilizing Ephemeroptera, Plecoptera, and Trichoptera (EPT) as bioindicators. Conducted between March and April 2021, the study spanned eight carefully selected observation stations, covering the river's course from upstream to downstream. The evaluation of water quality is undertaken through a quantitative analysis of biotile diversity parameters, encompassing calculations of EPT diversity, percentage abundance, and the overall diversity of macrozoobenthos families. From the research findings, it was revealed that the Bone River hosts 16 EPT families, comprising a total of 1438 individual observations. Across the eight stations, the diversity of the EPT family encompassed 16 taxa, inclusive of 7 Ephemeroptera and 9 Trichoptera taxa, with Plecoptera notably absent. Notably, the results of the Biotilik examination yielded a score of 2.28 for the water quality of the Bone River. This score indicates a pollution burden on the river, as evidenced by elevated Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) concentrations at select observation sites, surpassing established quality standards. Furthermore, the absence of macrozoobenthos, particularly Plecoptera, which are known for their sensitivity to pollution, further underscores the compromised state of the river's water quality.

Abstract

Coral reef ecosystems are vulnerable to damage. This ecosystem is found in tropical and subtropical seas and consists of reefs (calcareous structures) derived from coral animals and other biota. Considering these issues, efforts are needed to find other ways to enhance the exploration of marine resources without causing damage or increasing environmental productivity. This research employs the process of literature review. The results of article searches in the identified databases show that there are various factors that cause damage to the coastal coral reef ecosystem. There are two human (anthropogenic) factors, including the dumping of garbage into the sea, the use of destructive fishing tools, the mining of corals for consumption, and the temperature, brightness, and predators of coral. The damage to the coral reef ecosystem is caused by the human factor (80.98%) compared to the natural factor (58.09%). Addressing this problem, coral reefs in Indonesia have been saved through rehabilitation and conservation using techniques such as spider web transplantation and hybrid shelves and cor, as well as developing CMRIS (Coral Reef Management Information System) and COREMAP (Coral Reef Rehabilitation and Management Programme) as technology systems.

Abstract

This study aims to identify the utilization of Non-Timber Forest Products (NTFPs) in the mangrove ecosystem and analyze their impact on the livelihoods of coastal communities in Teminabuan District, South Sorong Regency. The research was conducted from July to September 2024 using direct interviews with 50 respondents selected through purposive sampling, specifically community members who utilize mangrove resources. Data were collected through inventory to obtain comprehensive information on the types, quantities, and productivity of each NTFP commodity, and then analyzed using qualitative descriptive methods. The results indicate two main categories of NTFP utilization: flora (mangrove leaves, pedada, nipah, coconut, and rattan) and fauna associated with mangroves (honeybees, crabs, clams, ants, catfish, and shrimp). The utilization of NTFPs includes direct consumption, traditional medicine, sales, tourism, and garden creation. Mangroves play an important role as a source of food and livelihood for coastal communities, thus the utilization of NTFPs is carried out sustainably. This study provides baseline data on the potential of mangrove NTFPs in Teminabuan District, supporting sustainable management, community empowerment, forest conservation, and the improvement of coastal community welfare. These findings contribute to local economic development and the conservation of mangrove ecosystems in Southwest Papua.
