Abstract

Plastic is one of the materials most widely used by humans. The more plastic that is used, the more plastic waste is released into environment and will polute water areas in various sizes, both macroplastics and microplastics. Microplastic are classified as plastic particles whose diameter is less than 5 millimeters. One type of microplastic that has an adverse impact on the life of aquatic organisms is polyvinyl chloride (PVC). The aim of this research was to determine the effect of PVC microplastic exposure on the survival rate and growth performance of tilapia, Oreochromis niloticus. This study was conducted in a completely randomized design (CRD) consisting of four treatments with three replications. The treatments were as follows: MP0 = No addition of microplastics (control); MP1 = Addition of 5 mg/L microplastics; MP2 = Addition of 15 mg/L microplastics; MP3 = Addition of 20 mg/L microplastics. The results showed that exposure to polyvinyl chloride microplastics on the survival rate and growth performance of tilapia through water made a real difference to Survival Rate (SR), absolute weight growth, absolute length growth, Specific Growth Rate (SGR), Feed Convension Ratio (FCR) and the abundance of polyvinyl chloride microplastics in fish gut.Keywords:MicroplasticPolyvinyl chlorideTilapiaSurvival rateGrowth performance

Abstract

Research related to the influence of facilities on the quality of fish landed and auctioned has been done previously, but the catches under this study are still limited to large pelagic fish with complex fish auction facilities. This study was conducted for small pelagic fish where the handling facilities at this location are still very limited. Therefore, survey research with purpose to analyze the effect of handling facilities (ships, fish auction sites, baskets) on the quality of small pelagic fish. The data taken is daily data with the method of observation at the location on the ship, fish auction place, and baskets. The species that taken were Eleutheronema tetradactylum, Ilisha elongate, Pampus argenteus, and Johnius trachychepalus. Each species consists of 5 individuals. Its tests was done by looking at the organoleptic and pH values. The tests were done to every species of fish. The pH value was obtained by testing the fish meat sample on the meat pH meter, while the organoleptic value was obtained by looking at the physical condition of the fish using a score sheet of fresh fish quality parameters. Then after the results are obtained, an analysis is carried out to determine the magnitude of facility influence on fish quality by simple linear regression analysis. The organoleptic values of four kinds of samples were on average 6.84 - 4.95, while the pH values measured in these fish ranged from 6.3 - 5.94. The effect of fish handling facilities on the organoleptic value is 82% compared to other factors. The fish quality as measured by the organoleptic test showed a fairly good quality, while measured by the pH test showed good results. Handling facilities do not greatly affect the quality of fish and there are other factors that can affect the decline in fish quality other than facilities. The relationship between fish handling facilities and quality can give an overview of the contribution of handling facilities to fish quality.Keywords:Fish auction marketFish qualityHandling facilities

Abstract

The marine ecosystems in the southern part of Rote Ndao District, within the Timor Sea, could be harmed by oil spills from ships or offshore rigs operated by oil and gas companies in the Timor Sea block, shared by Indonesia, Australia, and Timor Leste. The assessment using Environmental Sensitivity Index (ESI) maps using the thematic data. Areas identified as most sensitive to oil spills include West Rote district (Boa and Nembrala villages), and Southwest Rote district (Oeseli, Landu, and Manuk villages and Ndana islands). The beach type in Rote Ndao which is dominated by sloped sandy beach is a substrate type that is easy to clean from oil spill. Conversely, the biodiversity component has the highest sensitivity. The socio-economic components that are most sensitive to the effect of oil spills are the main sources of livelihood include seaweed cultivation, fisheries, and marine tourism. Oil spill mitigation in Rote Ndao must be focused on oil spill risk management in the hotspot area based on the environmental sensitivity index. A plan to prevent oil spills can be created, targeting these hotspots to establish an early warning system for effective mitigation.Keywords:Environmental sensitivity indexoil spillRote Ndaobiodiversityrisk management

Abstract

Gelatin, a valuable biopolymer, is commonly derived from animal by-products such as fish skin, providing a sustainable alternative to traditional bovine and porcine sources. The extraction process is influenced by factors like acid type and temperature, which impact both yield and quality. This study aimed to compare the effects of citric acid and acetic acid, at two temperatures (50C and 60C), on the gelatin extracted from yellowfin tuna (Thunnus albacares) skin. The extracted gelatin was evaluated for yield, proximate composition, functional groups using FTIR, and surface morphology through SEM. Results indicated that acetic acid produced a significantly higher yield than citric acid at both temperatures, with the highest yield (10.10%) at 50C and the lowest (2.46%) from citric acid at 60C. Gelatin extracted with acetic acid also had higher protein content and lower moisture and ash levels. FTIR analysis confirmed the presence of characteristic gelatin functional groups, including Amide I, II, and III. SEM images showed a denser and more uniform structure in acetic acid-extracted gelatin, while gelatin extracted with citric acid had a more porous and irregular surface. SDS-PAGE analysis revealed stronger protein bands for gelatin extracted with acetic acid, indicating higher protein content and a more efficient extraction process. Both acid-extracted gelatins showed -chains and -chains, characteristic of denatured collagen. In conclusion, acetic acid proved to be more effective than citric acid in producing higher yield and superior quality gelatin from yellowfin tuna skin. Further studies should assess the gel strength and amino acid composition of the extracted gelatin.Keywords:environmental chemistrybelow waterbiopolymergelatinmarine chemistrywaste valorizationyellowfin tuna

Abstract

The black sea cucumber Holothuria atra was used in integrated aquaculture with sea bass juveniles (Lates calcarifer) as the lowest and highest trophic level organism, alongside the seaweed Gracilaria sp. as an organic extractive organism. Therefore, this study aimed to assess the potential of integrated aquaculture combined with sea bass juvenile and seaweed to support the growth of the black sea cucumber. The experiment was carried out using a completely randomized design with 3 fish density treatments (50, 100, and 150 fish/m3), each integrated with 10 bags of seaweed and 4 individual black sea cucumbers. The study was conducted for 8 weeks and the fish were fed with trash fish at 10% of body weight. Water quality parameters were measured in situ every day except for TOM, ammonia, and nitrate which were measured at the beginning, middle, and end of the study. The results showed that the specific growth rate of the black sea cucumber ranged from 0.31-0.45%/day. The black sea cucumber was able to use the feed and metabolic waste produced by the culture of sea bass, showing the highest growth rate at a density of 100 fish/m3. Water quality parameters remained in ranges considered suitable for growth, except salinity. Furthermore, the black sea cucumber was found to have a strategy for adapting to fluctuations in salinity, as shown by the ability to survive at 15 ppt.Keywords:Sea bass juvenilesSeaweedSalinityTOM

Abstract

The lack of information regarding the existence of potential natural resources supporting tourism activities and the suitability and capability of resources to support the implementation of good tourism activities can be a factor that hinders the sustainability of tourism in Kurenai Beach. Beach tourism activities can make a positive contribution to economic growth and the level of community welfare. On the other side, these activities also negatively impact the sustainability of coastal resources. For this reason, it is necessary to limit the tourists according to the carrying capacity of Kurenai Beach. This research gave the initial information to support the sustainability and management of Kurenai Beach tourism, Bone Bolango Regency. This research aims to determine potential resources through regional suitability and carrying capacity. Further, it is expected that the result of this study can be used as a recommendation in preparing a tourism development policy plan for Kurenai Beach, Bone Bolango Regency. The research was conducted from March to August 2023 in Tomini Bay waters, Kurenai Beach. This is a survey and interview research. The types of data used in this research were primary and secondary. The analysis used in this research was suitability analysis and carrying capacity analysis to determine the resource potential of Kurenai Beach. The research results showed that the suitability of Kurenai Beach tourism in the beach recreation category was divided into 3 (three) suitability categories, namely very suitable (S1), suitable (S2), and not suitable (S3). The carrying capacity of the Kurenai Beach tourist area could accommodate around 33,840 people/month. Kurenai Beach has some potential resources that are very suitable for beach tourism, amounting to 15,379 m2 and the total visitors of Kurenai Beach has not exceeded the carrying capacity of the Kurenai Beach tourist area so optimizing its use and management is highly possible.Keywords:Natural resourcesSustainable tourismTomini BayBotubarani Village

Abstract

Canned fish industry production generates significant waste, which, if left untreated, can pollute the environment and have negative impacts. While solid waste from fisheries has been widely utilized, the utilization of liquid waste from fisheries remains uncommon. This research aims to analyze the chemical quality of liquid organic fertilizers and determine the best treatment between liquid waste from pelagic tuna canning and kepok banana peel extract. The research employed a laboratory experimental method with one treatment, which is different concentrations of liquid waste from fish canning and kepok banana peel extract, with four treatment levels and three replications: PO (700 mL liquid waste from fish canning), P1 (600 mL liquid waste from fish canning + 100 mL kepok banana peel extract), P2 (550 mL liquid waste from fish canning + 150 mL kepok banana peel extract), and P3 (500 mL liquid waste from fish canning + 200 mL kepok banana peel extract). The parameters observed were nitrogen (N) content, phosphorus (P) content, and potassium (K) content. The research data were analyzed using a completely randomized design (CRD). The data analysis results stated that the treatment levels of P0, P1, P2, and P3 had a significant effect on the quality of liquid organic fertilizer and were statistically significantly different on the levels of nitrogen, phosphorus, and potassium of liquid organic fertilizer products. The results indicate the appropriate formulation for liquid organic fertilizers nd the best chemical quality, which is treatment level P2 with a formulation of 550 mL. liquid waste from fish canning, 150 mL. kepok banana peel extract, 300 mL. coconut water, and 40 mL EM4, yielding nitrogen (N), phosphorus (P), and potassium (K) values of 3.18%, 5.47%, and 5.54%, respectively. These values meet the quality standard requirements for liquid organic fertilizers according to Minister of Agriculture Regulation number 70/Permentan/SR.140/10/2011, which is between 3-6%.Keywords:Fish wasteLiquid organic fertilizerNitrogenPhosphorusPotassium

Abstract

Poor water quality caused by the influence of activities on land and sea can disrupt the ecosystem and the existence of fish resources in coastal areas. Damage to fish habitat impacts fishing areas, resulting in a decrease in fishermens catches. Fish resources will move further away from the coast, resulting in a narrower utilization of sea space for small fishermen and leading to conflicts. Thus, this study aims to analyze the quality of the aquatic environment and map the pollution degradation in the northern waters of West Java Province. The survey method was used in this study. The types of water quality data measured were water clarity, sea surface temperature, salinity, light attenuation coefficient, total suspended solids, and chlorophyll-a. In-situ seawater quality measurements in coastal waters were carried out at 30 points. In-situ water quality data was compared with remote sensing image data. Water quality parameter data was analyzed descriptively by comparing the results obtained with seawater quality standards for marine biota based on the Decree of the Minister of Environment No. 51 of 2004 concerning Seawater Quality Standards. The results showed that the light attenuation coefficient and salinity parameter had an average that did not comply with the seawater quality standards for biota. The parameters of chlorophyll-a, brightness, suspended solids load, and sea surface temperature were still within the threshold of seawater quality standards for biota life (good condition). The environmental conditions of the northern waters of West Java Province are classified as good, were around 3,261.703 km2, while the lightly polluted area was around 3,043.452 km2. The northern waters of West Java Province, classified as lightly polluted, were concentrated in two locations, the northern waters of Bekasi, and Indramayu.Keywords:Quality standardsDegradationWest JawaWater qualityMapping
