Abstract

The utilization of mariculture fisheries resources in Ambon Bay faces several challenges, including technological limitations, limited market access, and suboptimal government policies. The Ambon City Government and the Maluku Provincial Government have designated this area for marine aquaculture development. Youth involvement is a crucial aspect, as young people serve as partners in the implementation of government policies. This study aims to identify the forms of youth involvement, government policies, and the utilization practices of mariculture fisheries resources in Ambon Bay. Data collection was conducted through interviews with 51 respondents. The identified forms of mariculture fisheries resource utilization include seaweed farming and fish cultivation using floating net cage systems. Youth involvement was categorized as follows: 5.9% as business owners, 68.6% as members of business groups, and 25.5% as laborers. Government policy interventions in the area include the provision of assistance or grants in the form of fish seed, feed, supporting facilities, and training by the Ministry of Marine Affairs and Fisheries, the Maluku Provincial Government, the Ambon City Government, as well as village and sub-district governments. These entities consistently provide support in the form of production facilities for fish farming using floating net cage systems. Government policies on youth empowerment need to be implemented comprehensively, beginning with the preparation of human resources (youth), the development of adequate competencies and skills, and the provision of accessible business capital. These efforts aim to encourage greater youth involvement in the utilization of mariculture fisheries resources in Ambon Bay.

Abstract

Pole and line is a fishing gear consisting of a fishing rod or bamboo which has a main rope, secondary rope and hook and is operated by hand with the target of skipjack tuna. Sometimes there are still fishermen who do not carry out fishing activities based on applicable regulations. The  study was carried out in Bitung with the aim of knowing pole and line fishing techniques, identifying the technical linkages of pole and line fishing in KM. Sari Usaha 09 with Permen KP 36 of 2023 and uses observation, documentation, and interview methods then is analyzed by descriptive and comparative. The technical connection between pole and line operations has discrepancies in Permen KP 36 of 2023 with  result research data with the criteria for vessel size, fishing line, FADs. Criteria for hook and rod length were taken from 3 journals/references on the operation of pole and line fishing gear in the North Sulawesi region. There is a discrepancy in the criteria for pole and line fishing gear because Permen KP 36 of 2023 does not discuss fishing hooks and rod length, so journals/references regarding the operation of pole and line fishing gear in the North Sulawesi region are cited. Regarding the results of the KPA regarding technical comparisons of pole and line operations with Permen KP 36, it is known that four criteria are suitable and one is not suitable, namely boat size, fishing line, FADs, and rod length while the criteria are not suitable, namely, hook size.

Abstract

Eucheuma spinosum seaweed is a species of seaweed that is quite abundant in East Sumba Regency, but its use is still limited. This seaweed is known to have a high carrageenan content and can be used as a stabilizer and emulsifier in cosmetic products, one of which is body lotion. This research examines different E. spinosum formulations (0%, 5%, 10%, 15%) on the characteristics of the body lotion produced. The research results show that the characteristics of body lotion have an average pH value ranging from 7.6-8.4, an IC50 value ranging from 259 ± 2.27 ppm to 454 ± 3.38 ppm, and does not meet antioxidant standards for cosmetic preparations. The homogeneity of body lotion still contains seaweed granules, which are not homogeneous. Different concentrations of E. spinosum did not significantly affect color, aroma, or texture. However, it affects absorption capacity.

Abstract

Mangrove ecosystems are characterized by the high diversity of associated biota found, such as sea scallops. Sea scallops are filter feeders and suspension feeders that live at the bottom of the waters by burying themselves in sediment. This study aims to determine the biological aspects of sea scallops (morphometrics, density, distribution, and growth) and ecological aspects (mangrove vegetation structure and knowing the condition of sediment fractions and organic matter) in Buruk Bakul Village, Bukit Batu District, Bengkalis Regency, Riau Province. Sampling was carried out on transects containing 9 plots measuring 1 x 1 m² with a depth of 30 cm and a distance between transects of 100 m. Sampling and observation were carried out 3 times with an interval of 2 weeks. The results showed that the morphometric size of sea scallops varied. The density value of lokan clams ranges from 150 ind/ha to 2,700 ind/ha, with the highest lokan density at station I, natural mangrove forest conditions, and no community activities. The distribution pattern of lokan clams is categorized as uniform with an average value of <1. The growth pattern of lokan clams shows a negative allometric pattern, namely b <3. The highest density of mangrove vegetation is at station I, with 1,522 trees/ha, in a good category. The highest sediment fraction is the mud fraction, ranging from 30.24% to 84.6%. The highest organic matter content is at station I with a value of 28.37%. The results of the study showed that the density, growth, and morphometrics of lokan clams in Buruk Bakul Village were significantly influenced by the ecological conditions of the mangrove forest, especially the density of mangrove vegetation, substrate composition, and concentration of organic matter in the sediment.

Abstract

Climate variations can affect sea surface temperature (SST), feed distribution, and fish habitat. Temporal analysis of SPL and chlorophyll-a can help identify the impact of climate change on capture fisheries productivity. This study aims to analyze the relationship between chlorophyll-a and sea surface temperature (SST) on the productivity of dominant capture fishery commodities in the southern waters of the Special Region of Yogyakarta I-FMA 573. Fisheries productivity data on five dominant fish species at the research site (yellowfin tuna (Thunnus albacares), skipjack tuna (Katsuwonus pelamis), savalai hairtail (Trichiurus savala), Indian scad (Decapterus russelli), and common dolphinfish (Coryphaena hippurus)) in 2014-2023 were collected from PPP Sadeng. Chlorophyll-a and SST data for 2014-2023 were obtained from Aqua Modis multisensory satellite imagery. The data was classified based on the four seasons in Indonesia allowing analysis of seasonal changes affecting fisheries productivity. Skipjack tuna has the highest productivity, with an average of 410,803 kg/trip, while common dolphinfish has the lowest productivity, with an average of 29,521 kg/trip. Based on the results of multiple linear regression, chlorophyll-a and SST had a significant effect on the productivity of yellowfin tuna, skipjack tuna, Indian scad, and common dolphinfish, so that chlorophyll-a and SST may indicate the presence of these fish populations. Meanwhile, savalai hairtail are not significantly affected by chlorophyll-a and SST, because many environmental factors affect including monsoon winds, currents, and rainfall.

Abstract

Unutilized mussel shells have the potential to become solid waste and potentially pollute the environment. In fact, the shell has a high calcium content of 61.39% which can be used as a precursor to hydroxyapatite. Hydroxyapatite is known to have antibacterial activity that causes dental caries, namely Streptococcus mutants. However, the antibacterial activity of HAp from mussel shells against S. mutans bacteria is not yet known. This study aims to determine the Minimum Inhibitory Concentration (MIC), Minimum Bactericidal Concentration (MBC) and determine the inhibition zone against S. mutants bacteria from hydroxyapatite of mussel shells. This research procedure started from hydroxyapatite synthesis, MIC test, MBC test, and inhibition zone analysis at several HAp concentrations, namely 12.5 mg/mL, 25 mg/mL, and 50 mg/mL, as well as positive control and negative control. The results showed that no KHM and KBM values were found at the HAp concentrations used. Furthermore, the diameter of the hydroxyapatite inhibition zone against S. mutants bacteria at concentrations of 12.5 mg/mL, 25 mg/mL, and 50 mg/mL, was 0 mm. Thus, the hydroxyapatite of mussel shells is neither bacteriostatic nor bacteriocidal.

Abstract

Male tilapia fish grow faster than female tilapia, so administering synthetic steroids orally or by soaking has proven to be the simplest, easiest, most effective and reliable technology for sex reversal of tilapia larvae to become males. This research was conducted to analyze the administration of 17α- methyltestosterone on the growth rate and feed conversion of tilapia (O.niloticus). This study used a completely randomized design (CRD) consisting of 3 treatments and 4 replications. The optimum dose used is (60) mg/kg feed, and 0.5 ml/l. The results of this study showed that body weight gain with oral treatment had the best average, namely 226.83c ± 11.88; average length 12.79b ± 0.99, specific growth rate (SGR) 5.46c ± 0.06 and FCR namely 1.05a ± 0.06. Research on the effect of using 17α-methyltestosterone on the growth of oral male tilapia fish obtained the best results by not exceeding the residue limit (5 µg/L or 5 µg/kg) of synthetic steroids in the body of tilapia fish.
