Abstract

This research was conducted in Bumi Dipasena Mulya, East Rawajitu District, Tulangbawang Regency, Lampung, which is known for its intensive farming and fishing activities, especially mullet fish. The research method used is experimental, by measuring physico-chemical parameters of waters including temperature, salinity, pH and dissolved oxygen (DO). The results of the study showed the average value of several histopathological indicators for mullet fish, namely endema on the gills (3), which indicates swelling of the gill tissue due to fluid accumulation in response to environmental stress, such as pollution. In addition, the necrosis value (1,08) reflects the death of cells in the gill tissue, which is caused by exposure to harmful substances, including heavy metals, which can damage gill function. Congestion (1,92) indicates a buildup of blood in the gill vasculature, associated with an inflammatory or stress response, which can disrupt blood and oxygen flow. These findings emphasize the importance of water quality management to maintain the health of aquatic biota.

Abstract

Microalgae is a photosynthetic microorganism that oftenly used as live feed for aquaculture. One of the species that mostly used is Thalassiosira sp. This species belongs to the group of diatom which has high nutritional content. The availability of nutrient in media is one of the main factor affecting growth and biochemical content of Thalassiosira sp. This study aimed to evaluate effect of cultivation media on the growth, biomass, and pigment content of Thalassiosira sp. This research consisted of four treatments and four replicates. The treatments included different cultivation media namely walne, Blue Green-11 (BG-11), Bold’s Basal Medium (BBM), dan f/2 (Guillard). During the study, growth was observed daily while biomass and pigment content were evaluated at the early stationary phase. The result showed that different culture media was significantly (p < 0.05) effect the growth, biomass, and pigment content of Thalassiosira sp. The walne medium produced highest growth, biomass, and pigment content. On the other hand, the lowest production of growth, biomass, and pigment content were obtained in BBM. This study indicated that the suitable medium for Thalassiosira sp. cultivation was walne.

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

Fish hybridization is the process of crossing two different fish species to produce offspring that have characteristics of both parents. The main purpose of hybridization is usually to combine superior traits from both species, such as faster growth, disease resistance, or improved meat quality. The experimental design used in this study was a completely randomized design (CRD) with 2 treatments and each treatment consisted of 3 replicates. The treatments were as follows: P1 = Koi X Koi Fish Hatchery (control), P2 = Koi X Kaviat Fish Hatchery. The results showed that the pH value in borehole water quality was 7.89 with Kohaku broodstock producing fecundity of 640 eggs, obtained an average Fertilization Rate (FR) of 17.29% resulting from the average of each egg sample calculation. The highest number of fertilized eggs was found in the PIU1 treatment which was 1470 eggs and the average Hatching Rate (HR) was 49.35%. The conclusion of this study is that hybridization between Koi and Kaviat fish can produce good potential performance based on water quality that can be maintained well with test parameters seen from fecundity, FR, HR, Length Growth, and good Survival Rate (SR).  Superior fecundity and quality in the hybridization process between koi and caviat fish can occur well if several environmental factors such as temperature and pH are still on an optimal scale.

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

Microalgae give an idea of the fertility of a body of water because the more microalgae in a body of water, the more fertile the water is. This research aims to determine the structure of the microalgae community in the Umbul water tourism area of Klaten Regency. This type of research is descriptive quantitative with a survey method. The data collection technique uses purposive sampling with hand-collection techniques. The data analysis technique uses the Shanon-Wiener diversity index (H'), species evenness index, dominance index, and species richness index as well as looking at physical and chemical parameters to determine water quality. The most common microalgae come from the Bacillariophceae and Cyanophyceae classes.The Shannon-Wiener diversity index for the three stations is in the stable category but the highest index value is at station III at 2.860 and the lowest index value at station I is 2.427. The highest species evenness index was at station I, namely 0.864, and the lowest index at station II was 0.764, so the species evenness index was stable. The highest Dominance Index at station II is 0.13 but is still close to 0 so the dominance index is low. The highest species richness index was at station III and the lowest at station II was 4.83. According to the results of the Umbul Nilo diversity index, Umbul Ponggok and Umbul Sigedang are included in the unpolluted category

Abstract

Selected as the National Fish Reserve (LIN), Maluku Province is known for its abundant marine resources and enormous fishery potential, supported by a capture fishery area of 658,294.69 km² which is the largest in Indonesia. Maluku has three Fishery Management Areas of the Republic of Indonesia (WPPNRI), namely WPPNRI-714, WPPNRI-715, and WPPNRI-718. However, based on production data for the capture fishery and aquaculture sectors in Maluku Province during the 2018-2022 period, these resource potentials have not been optimally utilized. Therefore, this research aims to analyze the ecological conditions and utilization of fishery resources in Maluku Province as a consideration for developing targeted policies and strategies for fishery resource utilization. This research uses a quantitative descriptive approach with data presented in narrative format, simple tables, graphs, and Multidimensional Scaling (MDS) analysis. Data collection was conducted from various sources over a 5-year period (2018-2022). Based on the analysis results, the status of ecological conditions and fishery resource utilization in Maluku Province is classified as less sustainable, indicated by Rapfish scores below 50. To improve the sustainability of fishery resource management in this region, strengthening of monitoring systems and community education about the importance of aquatic ecosystem conservation is needed.

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.
