Abstract

This research was conducted on one of the Siak River tributaries that crosses the urban area in Pekanbaru, namely the Pengambang River. The Pengambang River flow is dammed to become a reservoir; one of its functions is as a source of raw drinking water. Increased activity along rivers and reservoirs certainly has an impact on water quality. The research was carried out in May-October 2023. Water sampling was taken at 3 points each along the river flow and in the Reservoir. The physicochemical water quality parameters measured include temperature, TSS, BOD, COD, DO, pH, TP, Nitrate, and Total coliforms for rivers and reservoirs, while Chorofil-a only for reservoirs. Water quality was evaluated using CCME-WQI, and the results of water quality evaluation according to CCME-WQI in the Pengambang River at all sampling stations could have been bad to marginal. At the same time, in the Reservoir, it was marginal. The CCME_WQI Index value in rivers ranges 42.33 to 54.97, while in reservoirs, it is higher 49-56, it indicated water quality in reservoir better than river. Parameters influencing water quality in rivers and reservoirs, especially TC and BOD come from household waste cage fish cultivation.

Abstract

Seaweed cultivation in Majene Regency, West Sulawesi, has not experienced significant development as in neighboring Polewali Mandar and Mamuju Regency. This can be seen from the absence of active seaweed cultivation activities in Majene Regency. The aim of this research is to assess the physical and chemical aspects of water to determine the suitability of locations for cultivating Eucheuma cottonii seaweed in Majene waters. The method used to measure ecological suitability included parameters such as temperature, salinity, dissolved oxygen (DO), pH, phosphate, nitrate and salinity. Subsequently, the data is scored to determine suitability classes: suitable (S1) with values ranging from 37 to 48, moderately suitable (S2) with values between 36 and 25 and non sultable (S3)/N) with value 25. The results showed that after applying weighting and scoring, locations such as East Banggae, Pamboang 1, Tubo Sendana, and Sendana 2 showed suitable scoring result with scores of 39, 39, 40, and 40. While locations such as Pamboang 2, Pamboang 3, Malunda, and Sendana 1 showed moderately suitable scoring results with scores of 33, 33, 34 and 36. Majene waters have potential areas for seaweed cultivation based on classes S1 (suitable) and S2 (moderately suitable).Keywords:SeaweedMajene WatersLocation SuitabilityWater QualityAquaculture

Abstract

Coral reefs in Tobok Batang, a nearby estuary of Bontang Regency, have a vital role in the threatened ecosystem due to non-environmental-friendly fishing practices and a global threat in the form of coral bleaching. In response to these conditions, PT Pupuk Kalimantan Timur initiated the Kilau Samudera Program to support damaged coral reef recovery through community-based rehabilitation by developing and maintaining artificial reef modules. The study objective was, therefore, to determine the rehabilitation efficacy in Tobok Batang, through (1) coral growth informed by colony diameter, and (2) targeted reef fishes informed by abundance and biomass. Data was collected by purposive sampling in eleven clusters of three modules: pyramid, dome, and cube. The result shows that coral had been found attached in all these eleven clusters, while the targeted fishes had been found in most clusters. Clusters deployed in 2015 and 2017 have an average colony diameter of 30 cm (SE), the two highest among the other clusters. The highest abundance of corallivores was found in the cluster deployed in 2017 and 2020 (9 ind/100 m2). The highest herbivore abundance also was found in the cluster deployed in 2017 and 2020 (23 ind/100 m2), while its highest biomass was found in cluster 2020 only (40 kg/100 m2). The highest carnivore abundance was found in cluster 2017 only, with four fish per 100 m2 as well as the biomass in the same cluster (9kg/100 m2). All these cluster groups have provided new habitats in shallow waters, indicating that the cluster has a good position and probably good material composition that can trigger coral juveniles to attach, settle, and grow, which also became a unique habitat for some targeted reef fish. This study showed that the location and these three modules were proven effective for rehabilitating methods in damaged coral reefs.Keywords:Coral Reef,Rehabilitation,Tobok Batang,Bontang,Reef Fish

Abstract

To overcome excess residues and fish mortality rates during transportation, natural ingredients, namely clove oil, can be used. Compounds in clove oil are considered safe because they use natural ingredients. The purpose of this study was to determine the effectiveness of using clove oil as an anesthetic agent with different doses on the length of time of unconsciousness and survival rate of tilapia. This research was conducted from May to June 2023. This research was carried out at the Bungus Fish Seed Center, Padang, and West Sumatera. The method used in this study is the experimental method. The design used in this study was a completely randomized design (CRD) consisting of 4 treatments and 3 replications. The treatment used in this study is use of clove oil with different doses. Treatment A1 = 0.5 ml L-1 water, A2 = 1 ml L-1 water, A3 = 1.5 ml L-1 water and A4 = 2 ml L-1 water. Observations of changes in tilapia behavior and water quality were analyzed descriptively, while the length of time of stupor and survival of tilapia obtained during the study were analyzed using analysis of variance (ANOVA). To see the differences between treatments, the Duncant Multiple Range Test (DMNRT) was performed. Data is processed using the SPSS 26 program. The conclusion that can be considered in this study is that the administration of clove oil with different doses as an anesthetic has a significant effect on the longest induction time, on the length of time the fish were unconscious, the length of time the fish regained consciousness and survival rate of tilapia. In treatment A2 with a dose of 1 mL L-1 of water, it was optimal to stun tilapia for 244 minutes with a survival of 88.89%.Keywords:Clove oilFish transportationTilapia

Abstract

Phytoplankton blooms in the lake cause ecological, economic, health, energy, and aesthetic losses. It reduces water quality and biota diversity, creates toxins in the waters, and changes the structures and functions of the ecosystem. The essential nutrients for the growth of phytoplankton are nitrogen and phosphorus. Controlling phytoplankton growth can be managed by controlling the limiting nutrient input. This study aims to identify the limiting nutrient, analyze variations in TN:TP ratio spatially and temporally, and model TN:TP ratio and chlorophyll-a relationship. This study used secondary data from previous studies, namely TN, TP, and chlorophyll-a observed monthly in seven stations purposively during a year. Rainfall data was also obtained from the previous study. Limiting nutrients were determined by Redfield theory, and data were analyzed by Spearman correlation, One-way ANOVA, Kruskal-Wallis, and regression analysis. The results showed phosphorus was a limiting nutrient for phytoplankton growth in Lake Laut Tawar. TN:TP ratio and chlorophyll-a did not vary spatially, indicating the lake surface waters were evenly mixed. The parameters varied temporally, expressing the influence of hydroclimatological factors, especially rainfall. Rainfall increases nutrient input to the lake, but only rain below 200 mm/month causes an increase in the concentration of nutrients in the lake. The rainfall above 200 mm/month increases lake water volume significantly, thereby reducing nutrient concentrations. TN:TP ratio and chlorophyll-a related negatively and formed a non-linear relationship with an empirical model Chlorophyll-a = 2770.285 (TN/TP)-1.871. Eutrophication of Lake Laut Tawar should be anticipated by controlling the anthropogenic phosphorus input.Keywords:AnthropogenicChlorophyll-aEutrophication,Limiting nutrientRainfall

Abstract

Plastic waste that is not managed properly will damage the environment by polluting the ecosystem. Plastic in waters can turn into micro-sized plastic waste. Plastics whose size is less than 5 mm are called microplastics. The emergence of microplastic pollutants is caused by increasing population activity in Percut Waters. Percut waters are waters located in the coastal area of North Sumatra where there are many anthropogenic activities that cause the emergence of microplastics. Microplastics can have a negative impact on exposed marine biota. Nowadays microplastics are not only found in the environment, but can also accumulate in the bodies of organisms, for example. This research aims to determine the abundance of microplastics in fish found in Percut waters. The research was carried out in October November 2022 in Percut Waters. Fish samples were caught using nets and the samples were separated from their digestive tract and diluted with the addition of NaCl and H2O2 lauric. The average abundance of microplastics in fish samples ranged from 24294 particles. The fish species where the most microplastics were found was mullet fish with 294 particles. The most common types of microplastics found in total are fiber microplastics.Keywords:MicroplasticDigestionCoastalPercut

Abstract

Contamination of palm oil mill effluent (POME) into water bodies potentially increases turbidity, resulting in disrupting aquatic organisms behaviour, including predation period. However, the effect of increased turbidity due to POME contamination toward the fish predation is still unexplored. Siamese fighting fish (Betta splendens) is one of the ideal test fish to investigate this effect. This study aims to analyze the effect of increased turbidity due to POME contamination toward the fish predation period of Siamese fighting fish. The research design was completely randomized with six treatments (0, 20, 40, 60, 80 and 100 NTU) followed by five repetitions for each treatment. The experimental data parameters include the predation rate of Siamese fighting fish during foraging activity, which was calculated from the percentage of the number of mosquito larvae consumed per 2 min during 15 min. The significance level of predation between treatments in each observation time period was analyzed using a one-way Analysis of Variance (ANOVA) with the confidence interval set at the 95% level. The results showed that at a turbidity level of 100 NTU, the predation period of Siamese fighting fish had been altered. In the period of 0-2 min, the predation rate decreased significantly. Meanwhile, the predation rate increased significantly during the period of 2-4 and 8-10 min. This finding should be considered to support POME remediation management, especially turbidity parameters.Keywords:POMEFeeding periodForaging areaTurbidity

Abstract

Rewataya Village is situated on Tanakeke Island, within the Takalar Regency. Despite its significance, previous studies have not addressed the mapping of changes in mangrove land area within this locale. The present research aimed to fill this gap by assessing alterations in mangrove land area from 2013 to 2023, alongside examining density and canopy cover conditions. The method employed for mapping changes in land area entailed utilizing the unsupervised method with maximum likelihood classification. Additionally, the assessment of mangrove conditions involved employing plot line transects to determine species density and hemispherical photography methods to evaluate canopy cover. Notably, two types of mangroves, namely Rhizophora mucronata and Rhizophora apiculata, are prevalent in this village. The mangrove species density in Rewataya Village, Tanakeke Island, is categorized as good. In addition, the canopy cover in Rewataya Village falls within the classification of very dense according to mangrove damage criteria. However, there has been a notable reduction in the mangrove ecosystem area between 2013 and 2023, with a decrease of 42.28 hectares (from 367.13 hectares to 324.84 hectares).Keywords: MangroveLandsat 8Rewataya villageUnsupervised
