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

Abstract

Sea cucumbers are a type of marine organism with significant economic worth and potential applications as nutraceuticals. This marine organism possesses possibly useful chemicals, making it a viable alternative for the fisheries product processing businesses. The objective of this study was to assess the efficacy of the methanol extract of Holothuria atra in preventing the formation of calculi and its ability to inhibit the growth of bacteria. Extraction was performed using the maceration method with methanol as the solvent over a period of 72 hours The analysis revealed the presence of four bioactive components in the methanol fraction: alkaloid, triterpenoids, flavonoids, and saponins. In vitro anticalculi activity was assessed by measuring the decomposition of kidney stones (Ca) using an atomic absorption spectrophotometer (AAS). The maximum decline of calcium stones was regarded at a concentration of 500 ppm of sea cucumber extract. The disc diffusion method was employed to assess the antibacterial activity against Escherichia coli and Staphylococcus aureus. The inhibition zone diameter was measured at all concentrations (25%, 50%, 75%, and 100%), indicating their potential as antibacterial agents. The greatest level of antibacterial effectiveness against Escherichia coli was observed at a concentration of 50%, resulting in a zone of inhibition of 1.90 mm. In contrast, the most significant antibacterial activity against Staphylococcus aureus was observed at a concentration of 25%, resulting in a zone of inhibition measuring 4.50 mm.Keywords:Holothuria atraExtractMethanolAnticalculiAntibacteria

Abstract

Activities around Bone River, one of the largest rivers in Gorontalo Province, include agriculture, settlement, gold mining, sand excavation, industry, and illegal logging. This research aimed to report the water quality status of Bone River using the STORET method as an index commonly used for measuring pollution levels in a water body, which the Indonesian government regulates, as stated in the Decree of the Minister of Environment, No. 115, 2003. This work involved data from 2021-2023 along the upstream to downstream of the river. There were 12 water quality parameters measured: temperature, TSS, DO, pH, COD, BOD, nitrate, phosphate, ammonia, and the heavy metals (Pb, Cd, and Hg) concentration. This study revealed that parameters met water quality standards for class I and class II: temperature, pH, DO, Pb, and Cd. The index scores ranged from -96 to 0. The upstream area was categorized as good, and the midstream to downstream was recognized as heavily polluted. This pollution level is dominated by organic waste from agricultural and domestic household activities. The concentration value consistently exceeds the quality standard in all data from St 5 to St 12. These two parameters are enough to significantly cause worsening water quality based on the STORET with a total score contribution of -40. BOD and COD parameters contribute the most to the river pollution level.Keywords:Water qualityPollutionSTORETBone River

Abstract

The spot-tail shark, Carcharhinus sorrah is a species of requiem shark found primarily in warm coastal waters of the Indo-Pacific region. This study aims to assess the length at first maturity and length distribution The spot-tail shark, C. sorrah collected from key fish landing sites in Aceh Province, Indonesia. Data collection occurred between March 2020 and October 2022 at three fishing ports: Banda Aceh (BA), Aceh Barat (AB), and Aceh Barat Daya (ABD). A One-way Analysis of Variance (ANOVA) was employed to analyze the total length (TL) of male and female fish from these sites. Results indicated an overall sex ratio of female to male fish at 1:1.67 ( = 45.19, p 0.001), with significant differences observed in sex ratios between BA and ABD ( = 6.72, p = 0.01; = 41.14, p 0.001), while AB showed no significant difference ( = 1.64, p = 0.20). Logistic regression analysis revealed variations in the length at which 50% of males and females reached maturity (Lm50): males from ABD, AB, and BA were 110.65 cm TL, 117.03 cm TL, and 152.65 cm TL, respectively, while females from BA, ABD, and AB were 107.30 cm TL, 113.94 cm TL, and 116.14 cm TL, respectively. Notably, males from ABD and females from BA matured earlier than those from other sites. In terms of length distribution, the average greatest with standard deviation (SD) length of male C. sorrah was 122.8737.87 cm TL in AB, followed by BA at 113.8013.10 cm TL and ABD at 107.8618.38 cm TL. This species is important for both ecological balance and fisheries, emphasizing the need for effective management and conservation efforts.Keywords:The spot-tail sharkCarcharhinus sorrahsex ratiolength at first maturitywesternmost Indonesia

Abstract

Characteristics of plastic debris were assessed among two types of beaches on Bawean Island (windward and leeward) to analyze its sources and long-term effects. Plastic debris was collected inside a 5 x 5 meter transect with five transect plots on each beach per 20 meters. Samplings were carried out three times at intervals of seven days from six different beaches. The average abundances of plastic debris were almost similar between leeward (0.1690.123 pcs m-2) and windward beaches (0.8410.577 pcs m-2). On the other hand, in terms of weight, leeward beaches contained a very low value of debris (0.9270.746 g m-2) compared to windward beaches (4.4793.551 g m-2). Sheets on the windward beaches and wholes on the leeward beaches dominate the shape of plastic debris with the average size was 1520 cm. The color on both type of beaches was dominated by white (38%) and blue (12%). The weathering intensity is 48% on the leeward beach and 52% on the windward beach. The absence of significant differences in size, color, and weathering intensity implies that the debris found came from the same source. The large size and low weathering intensity of the plastic debris means that the debris has not been exposed to hydro-oceanographic factors for an extended period and they came from a local source. The difference in abundance and shape of plastic debris suggests that wind still plays a vital role in shaping the characteristics of plastic debris on Bawean Island.Keywords:Marine DebrisPlastic WeatheringWind DirectionMarine PollutionMacroplastic

Abstract

Poropuntius tawarensis is an endemic fish of Laut Tawar that is currently classified as Endangered according to the IUCN Red List. The decline in its population is caused by habitat degradation, overfishing, and the introduction of alien species that act as predators This study aims to analyze the diversity and distribution patterns the population of kawan fish (Poropuntius tawarensis) in Lake Laut Tawar, Central Aceh Regency. Fish samples were collected from four different locations and analyzed using the Shannon-Wiener and Morisita indices. The results indicate that the diversity level of kawan fish (Poropuntius tawarensis) is classified as a "Low level of diversity," with significant differences between sampling locations. All locations (Hakim Balai Bujang: 0.796845; Toweren: 0.301815; Kelitu: 0.753952; Kala Segi: 0.467728) show a low level of diversity, which is H' 1. Analysis using the Standardized Morisita Index indicates that the distribution pattern of kawan fish (Poropuntius tawarensis) in the four study locations tends to be clumped dispersion. This is evidenced by Morisita index values greater than 1 at all sites (Hakim Balai Bujang: 1.2834; Toweren: 1.0212; Kelitu: 1.0053; Kala Segi: 1.0134). These values suggest that the fish tend to concentrate in specific areas within each village rather than being evenly distributed.Keywords:Poropuntius tawarensisLaut Tawar LakeDiversityDistribution Patterns

Abstract

Goonch (Bagarius yarelli) is one of the local fish species affected by dynamic changes due to activities along Perjaya Dam. The first component in conducting the cultivation of local fish is domestication The main problem in domestication is the adaptation of wild fish to the controlled environment. Another aspect that needs to concern in domestication is the defense of domesticated species from several pathogens, especially parasites because most of wild fish captured from natural habitats are attacked by several parasites. This study aimed to determine the prevalence and intensity of ectoparasites attacked goonch captured from Perjaya Dam. The sampling method used was purposive sampling method and followed by laboratory examination. A total number of 90 goonch were collected using fishing rods and gillnets with an aid from local fishermen during this study. Ectoparasites were examined on several external organs including skin or scales, fins, and gills. Ectoparasites found during the sample examination were recorded for further calculation of ectoparasites types, prevalence, and intensity. The measurement of water quality parameters was performed after sample collection. Water quality parameters measured consisted of temperature, pH, dissolved oxygen, ammonia, and transparency. Goonch captured from Perjaya Dam were infested by Lernaea sp. and Gyrodactylus sp. through single infestation and with the same prevalence level (1.11%). Lernaea sp. showed a higher intensity (52 ind/fish) on goonch than that of Gyrodactylus sp. (1 ind/fish). Almost all water quality parameter in sampling site, including temperature, pH, and dissolved oxygen, were in normal ranges to support the live of freshwater fish.Keywords:EctoparasitesGoonchGyrodactylus sp.Lernaea sp.Prevalence
