Abstract

The spiny eels (family Mastacembelidae) is a fish that naturally and widely distributed on Java Island, especially in the Brantas River of East Java. This fish has high economic value, as a source of protein for local people and has recently popular as an ornamental fish among hobbyists. To fulfill market needs, fishermen must catch the fish from nature, leading to a severe population decline. Basic scientific information regarding species identification and determining the phylogenetic position fish species including the spiny eels is very important in order to support aquaculture, domestication and maintain its sustainability in nature. Specimens of the spiny eels were collected from Brantas River basin, East Java, at two localities in Malang and Kediri. Mitochondrial DNA from the cytochrome c oxidase subunit I was then sequenced on several randomly selected specimens. Results of morphological and genetic analysis using BLASTn showed that the specimens under study could be confirmed as Macrognathus aculeatus. Phylogenetic analysis using the Bayesian Inference method showed that M. aculeatus in this study has the closest relative to M. arai from Bangladesh. The phylogenetic reconstruction showed that individuals of M. aculeatus from Malang and Kediri were clustered together with individuals from Mojokerto with very shallow molecular divergence, indicating that they possibly originated from the same population. The results of this study can be used as basic information to design effective management of domestication, aquaculture, and conservation in the future.

Abstract

Gorontalo Bay, the estuary of the Bone River, is part of the Tomini Bay area. Nike, a school fish larva appearing in Estuary Bone only a few days monthly, suits the prima donna of the community and fishermen in Gorontalo. Any technical matters related to “nike” fishing have never been reported in a structured method. Therefore, scientific investigation is necessary to provide relevant information. This study aimed to identify the fishermen’s profiles and matters linked to “nike” fishing. Structured interviews using a questionnaire instrument were conducted to obtain information from Gorontalo fishermen who actively catch “nike” every month in Gorontalo Bay. The results showed that most “nike” Gorontalo fishermen are elementary and junior high school graduates aged 20-60. Nike fishing is done in groups using wooden boats with totalu'o or tagahu fishing gear. The operational fishing capital they used could be from boat owners, groups, or loans from fish collectors. Most fishermen sell their catch at the Fish Auction, Gorontalo City, with an average price of Rp. 20.000 to Rp. 40.000 per kg. According to fishermen, the “nike” fish population tends to be abundant in the waters during the east monsoon. When the population in the seas is high enough, the fishermen’s catch reaches more than 100 kg per trip. The high intensity of catching and the quantity of fish caught per season of emergence can threaten the sustainability of the “nike” population in nature. A more comprehensive follow-up study is needed to analyze the synergies of economic, social, and ecological aspects to increase “nike” fishermen’s welfare in Gorontalo with the sustainability of the “nike” fish guarantee.

Abstract

Fish resources Utilization in Southeast Maluku waters uses fishing gear, one of them is the bottom gill net. This study aims to determine the composition of fish species caught with different bottom gill net mesh sizes and the effective mesh size. The method used in this study was an experimental method of fishing with different mesh sizes, namely 2.5 inches and 3 inches, as well as data analysis using the paired sample t test. There were five types of catch obtained at a mesh size of 2.5 inches, namely Bubara fish (Carangoides bajad) totaling 54 individuals (22.41%), Cockatoos (Skarus dimidiatus) 46 individuals (18.67%), Samandar (Siganus canaliculatus 35 individuals (14.52%), Sikuda (Lethrinus atkinsoni) 39 individuals (12.45%) and Jackfruit seeds (Parupeneus indikus) totaling 24 individuals (9.96%).The mesh size of 3 inches obtained the type of Cockatoo fish (Skarus dimidiatus) totaled 27 individuals (30.58%), Jackfruit seeds (Parupeneus indikus) 14 individuals (15.91%), Bubara (Carangoides bajad) 13 individuals (14.77%), Samandar (Siganus canaliculatus) 11 individuals (12 .50 %) and sand (Pentapodus nagascokiensis) 6 (6.62 %). The total weight of the catch in basic gill nets with different mesh sizes, namely a 2.5-inch mesh size, obtained a total catch weight of 49,731.44 grams with an average catch per operation of 4,521.04 grams, while for mezh size 3 inches of 21,615.51 grams with an average per operation of 1,965.05 grams. Based on the paired sample t-test, it showed a significant difference in the use of different mesh sizes on the total weight of the catch, where the total weight of the catches obtained in the 2.5-inch treatment was more than in the 3-inch treatment, which means that hypothesis H1 is accepted Hₒ rejected.

Abstract

The rise of global surface temperature is predicted to increase the rainfall and runoff. Long-term changes in rainfall will affect the water resource, thus also influencing the fisheries and maritime sector. Understanding the global climate change and their effects, especially in Indonesia as one of the environmental condition parameters, is a part of the strategy for mitigation and adaptation towards climate change, and it is important to do early to support the sustainable development of Indonesia. Magicc-Scengen v5.3 is one of the widely-used climate models. Magicc is used in the projection of sea level and temperature, while Scengen is used to produce the regional climate change scenario with the resolution of 2.5°×2.5° latitude and longitude. This study aims to determine the climate change level especially the air temperature and rainfall in Indonesia using Magicc-Scengen model (global circulation model UKHADCM3 and UKHADGEM) using A1-BAIM and B2-MES scenarios. According to the Magicc-Scengen simulation model, in the year 2100, the global temperature will change from 2.5°C (B2-MES) towards 3°C (A1-BAIM). In Indonesia, the maximum change of temperature will occur on the A1-BAIM scenario, which is 2.12°C, distributed across Sumatra and Kalimantan. Moreover, on B2-MES scenario, the maximum temperature change is 1.88°C. The simulation results also show a rainfall escalation, from 25.4 towards 26.2%, in March-April-May (MAM) period. The A1-BAIM scenario determines that the highest rainfall will occur in MAM (for the year of 2050 and 2100), while B2-MES scenario determines that the rainfall pattern varies widely, in which the highest of it in 2050 will occur on December-January-February (DJF). However, for the year 2100, the highest rainfall will occur on MAM.

Abstract

Raja Ampat is one of the regions in Indonesia that implements the concept of sustainable marine tourism. The concept of sustainability for eco-resorts is adapted from the criteria of the Global Code of Ethics for Tourism (GSTC). The aim of this study is to find accurate data related to whether 8 resorts in South Waigeo have met the criteria for sustainable accommodation. Research is carried out with the collection of data quantitatively and qualitatively with descriptive analysis. The scores obtained are then processed on a likert scale with P=(F/Nx100%). The total sample was 96 people with a random sampling technique. The results showed GSTC criteria in 8 resorts obtained with a variable percentage. The lowest percentage is in the environmental sustainability criteria of 20-50% including indicators of nature conservation, natural resource management, waste and emission management, criteria for socio-economic improvement of local communities and criteria on the protection of cultural heritage indicate percentages below 55%, while organizational management criteria that include organizational structure, stakeholder engagement, obtain a percentagen of 49-63%. This percentage indicates that eight resorts do not meet the implementation of the criteria of sustainable water tourism, need seriousness together with all stakeholders in encouraging the tourism business to carry out the practice of Sustainable Tourism.

Abstract

The purpose of this study was to determine the potential formation of THM in surface water sources, namely Maruni River water and SP 6 River water in Manokwari Regency. Each sample was characterized for its physical and chemical characteristics including parameters of Total Organic Carbon (TOC), total suspended solids (TSS), ammonia, pH, turbidity, and conductivity (DHL). The ideal/correct concentration for chlorination of water samples is determined based on the need for chlorine which leaves a residual chlorine of 0.5 mg Cl2/L for 24 hours. The TOC content of the Maruni River and SP 6 River water samples were 0.5 mg C/L and 17.2 mg C/L, respectively. Both water samples were chlorinated with chlorine concentrations of 3.44 mg Cl2/L and 10.36 mg Cl2/L, respectively. In Maruni River water, the concentration of THM (read as chloroform) formed was 6.5 µg/L and Kali SP 6 water was 577.5 µg/L. The level of chloroform formed in the Maruni River water sample is very low compared to the required quality standard according to Health of Indonesian Ministry No. 907 of 2002 regarding requirements and monitoring of drinking water quality, which is 200 µg/L, so that the Maruni River water can be treated by chlorine to be used as drinking water.

Abstract

The high level of land conversion and utilization for wood extraction in the mangrove ecosystem in Bonkawir Village, Raja Ampat Regency impacts environmental degradation. Damage of mangrove ecosystems results in a decrease in the diversity and abundance of fish populations. The lack of scientific information about the current condition of the mangrove ecosystem on the coast of Bonkawir Village is an important reason to conduct a study related to the analysis of mangrove vegetation. This study aimed to identify mangrove species, describe the composition, density, frequency, dominance, and Important Value Index (INP) of mangroves on the coast of Bonkawir Village, Waisai District, Raja Ampat Regency. Data were collected using the line plot transect method at three observation stations then it is analyzed to find out the INP. Based on the observation, it is known that the types of mangroves found at the study site were 14 families consisting of 20 species. Species scattered throughout the station were Rhizopora apiculata, Rhizopora mucronata, Bruguiera gymnorrhiza, Xylocarpus granatum, and Derris trifoliate. The condition of the substrate which is dominated by muddy sand and water quality parameters that affect the growth of mangroves in general still meet the quality standards of mangrove growth. The Rhizopora apiculata had the highest Relative Density, Relative Frequency, and Relative Dominance in the tree category at Stations I and II so it had the highest INP at both stations. The tree category Bruguiera gymnorrhiza has the highest INP at Station III. At Station I the species with the lowest INP was found in Rhizopora mucronata; at Station II was Xylocarpus muloccensis. Meanwhile, Bruguiera parviflora and Ceriops decandra in the tree category together have the lowest INP at Station III.

Abstract

Microplastics are the result of degradation and fragmentation originating from plastics with a size of <5 mm. Currently, many people use broiler chicken intestines which are possibly contaminated by microplastics as food for pomfret (Colossoma macropomum) in floating net cages (KJA). The purpose of this study was to determine the number and type of microplastics present in the intestines of broiler chickens and the digestive tract of pomfret cages (C. macropomum) and to see the correlation level of the presence of microplastics in the digestive tract of pomfret (C. macropomum) fed using intestines. broiler chicken. The method used in this study was purposive sampling for the sampling of pomfret cages (C. macropomum). A sampling of broiler chicken intestines was carried out at random from KJA fish cultivators in Teluk Kenidai Village. The results obtained were microplastics of film type, fiber, and fragments found in the intestines of broiler chickens and the digestive tract of pomfret (C. macropomum). The number of microplastics found in broiler chicken intestines was 322 film particles, 112 fiber particles, and 52 fragment particles. While in the digestive tract of pomfret (C. macropomum) 343 are film particles, 203 fiber particles, and 63 fragment particles. The relationship between the presence of microplastics in the digestive tract of pomfret (C. macropomum) fed with broiler chicken intestines has a very strong relationship with a correlation value of 0.952.
