Abstract

Mangrove ecosystem is one of the unique ecosystems that has high productivity and it grows along the coast of Aceh Province, Indonesia. The mangrove vegetation in Aceh Tamiang District was decreasing due to human exploitation i.e. stems of mangrove vegetation utilized by local communities become charcoal and firewood. These activities have a negative impact on live and growth of mangrove vegetation. Therefore, the purposes of the study are to analyses the important value index (IVI), mangrove species diversity, and to analyses the correlation between substrate characteristics with mangrove density. The research stations determined using the purposive sampling method and each station has three plots as replication. There were 4 research stations located in Seruway, Bandahara, Banda Mulia, and Manyak Paye sub districts. The study reported 12 species of mangrove in the trees category, 9 species of saplings, and 8 species of seedlings. The 12 species of mangroves found were Avicennia lanata, A. marina, A. officinalis, Brugeira parviflora, B. sexangula, Ceriops decandra, C. tegal, Lumnitzera recomosa, Nypa fruticans, Rhizopora apiculata, R. stylosa, and Sonneratia alba. The R. apiculata was species commonly found in each sampling location and it had highest IVI for the tree, sapling and seedling categories with the value of 207.24, 300, and 200, respectively. The average of diversity index was 1.56 categorized in the medium category.

Abstract

Coffea canephora or robusta coffee was known as a medicinal plant that admitted various biological properties. However, its application as a medicinal plant in fish disease treatment has not been reported. This study aimed to investigate the effect of dietary robusta coffee leaf (RCL) extract on the survival rate and hematology of Cyprinus carpio infected by Aeromonas hydrophila. Two hundred fish were randomly divided into five treatment groups consisting of uninfected fish (UF), infected fish (IF), and a diet supplemented with different concentrations of RCL extract (30%, 40%, and 50%). The negative control group was injected by NaCl 0.9% and other treatment groups were injected by A. hydrophila. Feeding treatment was carried out for 7 days after clinical symptoms appeared. The results showed that RCL extract increases the survival rate and hematological parameters (number of erythrocytes, hemoglobin, and lymphocytes) significantly (P0.05). The highest survival rate (100%) was recorded in groups that accepted 50% of RCL extract. This current study indicates that RCL extract could be considered a potent medicinal plant for treating fish disease caused by A. hydrophila at the optimum dose of 50%.Keywords:AeromonasCoffea canephoraExtractHematologyCyprinus carpio

Abstract

Aquatic Tourism Park (ATP) of the Southeast Sulawesi Province has significant contribution to achieve the total targeted of 30 million of Marine Protected Areas (MPA) in Indonesia. The conservation area is located in 3 coastal districts of Konawe, South Konawe, and Kendari City Districts. The time-consuming process of legalizing the conservation area has driven the need to re-evaluate the ecological conditions from 2012 to 2020. The objective of this study is to this aims to determine the status, gaps and ecological feasibility of conservation areas in the Southeast Sulawesi region. One of the noticeable gaps is the change of ecological conditions in the reservation area. The gap could be identified by comparing ecological conditions before and after the area was reserved for a conservation area. Ecosystem suitability was measured by using ecological criteria, such as number of protected fish species, mangrove density, seagrass coverage, coral coverage, and naturalness. The score of suitability assessment was 31, which showed that the reserved location was suitable for a Marine Conservation Area. However, gap analysis results showed 10% decline in coral coverage and 17% decrease in seagrass coverage, while mangrove density decreased as much as 102 trees/ha during that period. Evaluation on the ecosystem condition was conducted by applying suitability analysis of the modified E-KKP3K dan Sambah et al. (2020) methods, resulting a status of suitable or conservation area allocation (score 31). Criteria used were chosen based on its contribution in facilitating important ecological processes and as ecosystem buffer system in the area. This study will give the implementation on MPA management optimalisation and it can be contributed on fisheries management.Keywords:Conservation areaFeasibility areaGapSoutheast Sulawesi

Abstract

The quality of the Siak River is gradually deteriorating with the rapid socio-economic development in its tributary watersheds. S. Sibam and Air Hitam are part of the Siak tributaries in the Siak tributary sub-region in Pekanbaru City. The quality of the Sibam and Air Hitam tributaries in the Siak Watershed of Pekanbaru City has been studied to determine the relative pollution level of water quality standards. Water quality measurements were carried out from January to August 2022 at the upstream, middle, and confluence with the Siak River. The pollution level of the Sibam River and Air Hitam River was measured using the pollution index method. The quality of the Sibam River and Air Hitam waters is compared to the quality standards according to The Regulation of Government of the Republicof Indonesia(RGRI) Number 22/2021 Class III. The water quality parameter measured consisted of dissolved oxygen, TSS, pH, BOD, COD, nitrate, nitrite, ammonia, and total phosphate. Pollution index calculations for the Sibam and Air Hitam rivers show light pollution, with index values ranging from 1.75 to 3.57. Nitrite and ammonia concentrations in the Sibam River do not meet quality standards. Whereas in the Air Hitam River, the BOD, nitrite, and ammonia level exceeds the quality standards (RGRI Number 22/2021 Class III). The highest pollution index is in the middle of the river, with settlements on both rivers.Keywords:Pollution IndexWater QualitySibam RiverAir Hitam River

Abstract

Women's forest in the local language called Tonotwiyat is a private space for women. Women's forests are not only limited to controlling disasters and neutralizing air pollution but are like mothers who provide life for local communities. This article is a literature study by conducting text and discourse analysis on socio-cultural events whose subjects are library materials. The results of this study indicate that the construction of the rowing venue has contributed to the damage to the women's forest ecosystem in Jayapura City. The tradition of protecting women's forests as a source of local food and as a place for character education for women is now starting to be eroded as a result of environmental pollution and land conversion. Rehabilitation is carried out as an effort by the government to preserve the damage to the mangrove ecosystem that has been affected by development. As a recommendation In addition to carrying out rehabilitation and revegetation, in the future it is necessary to expand by planting mangrove seedlings by colonizing new areas or extensification. Including the importance of regulations governing the protection and management of women's forests based on local wisdom adopted by the local community.Keywords:Women's forestMangrovesDevelopmentRowing venue

Abstract

One of the problems faced in the development of the marine and fisheries sector nationally is the low quality of the fish capture due to the limited capacity and quantity of available port infrastructure resulting in the decrease in competitiveness. The data in this study were related to fish capture from fishing boats to wholesalers. The data obtained was observation of the location of the vessel, the fish auction place, and the marketer. The types of fish taken were Kurisi (Nemipterus pneumatophores), Biji Nangka (Upeneus mullocensin), Kapas-Kapas (Gerres erythronium), Bawal Putih (Pampus argenteus), Kembung (Rastrelliger spp). Fish examining was done by looking at the organoleptic and pH values. The pH value was obtained by testing the pH meter, while the organoleptic value was obtained by observing the physical condition using a score sheet. To determine the magnitude of the influence of facilities on fish quality, and the correlation between organoleptic values and pH, an analysis using simple linear regression was conducted. The average organoleptic value of fish while on the boat, when distributed, and when in the marketplace were 8,248; 7,024; and 6.6 respectively. Meanwhile, the average pH value was 7.05; 5.51; and 5.15. The quality of fish caught at Class A Fishing Port of Belawan is still of good quality. The pH test showed decline in pH value ever since the fish was brought to the port until they were marketed. The influence of facilities on the fish organoleptic and pH value are 98.3% and 96%. Thus, facilities significantly affect fish quality at Belawan Fishing Port. Between pH and organoleptic values showed a positive correlation, hence when the pH value decreased, the organoleptic value also dropped.Keywords:Belawan Fishing PortEast WatersFacilities InfluenceFish Quality

Abstract

Microcytis sp is plankton species that is detrimental in shrimp pond ecosystems. The purpose of this study was to detect the abundance of plankton and the presence of Microcystis sp. in the waters of vaname shrimp (L. vannamei) aquaculture ponds. The research method used is descriptive quantitative and qualitative with added analysis of dynamic modeling systems. The results showed that pond water quality conditions were still good enough for shrimp farming activities with details of dissolved oxygen 4.01-6.17 mg/L, pH 7.7-7.9, salinity 20, temperature 27.050-28.250C, nitrate 0.01-0.15 mg/L, phosphate 0.05-0.20 mg/L, brightness 25-35 cm. For the classification of plankton found among them are from the Bacillariophyceae class, there are the genera Skeletonema sp., Cyclotella sp., Coscinodiscus sp., and Amphipora sp., from the Chlorophyceae class, there are the genera Chlorella sp., Oocystis sp., and Clamydomonas sp., from the Cyanophyceae class. the genus Oscillatoria sp., Microcystis sp., and Anabaenopsis sp. The plankton diversity index (H') was obtained between 0.01-0.33 and the uniformity index (E) was obtained between 0.10-0.50, meaning that the condition of the pond waters is still quite good and there are minimal indications of pollution. The abundance of Microcystis sp. obtained between 0.2x104-0.6x104 cell/ml. from the results of dynamic modeling analysis it is shown that the abundance of Microcystis sp. in pond waters is influenced by the value of the productivity level of the waters and the process of grazing organisms. The results of this study can be concluded that the plankton abundance rate found in ponds ranges from 0.4x104-1.9x104 cell/ml which consists of 10 genera and 3 classes of plankton. Then Microcystis sp. its presence was found in 3 ponds with abundance rate ranging from 0.2x104-0.6x104 cell/ml.Keywords:CultivationGenusGrazingModelWaters

Abstract

Vannamei shrimp (Litopenaeus vannamei) production continues to decline due to parasitic attacks on ponds in North Gorontalo Regency. Ectoparasites are one of the factors that can cause failure in the cultivation of vannamei shrimp. This study aims to determine the type of ectoparasites, intensity, and prevalence of vannamei shrimp cultured in traditional ponds in the North Gorontalo Regency. The sampling of the research was carried out at five research stations. The sampling of this research was taken at random in 5 plots of ponds and the total number of shrimps as many as 150 tails. At each station, samples were taken of 30 vannamei shrimp. Sampling using fishing gear in the form of nets. The observed samples were 8-10 cm in size alive. Observations of ectoparasites were carried out microscopically using a Zeis Binocular microscope with 10x magnification. Data analysis used descriptive analysis of the types of ectoparasites, intensity, and, the prevalence of ectoparasites found. The results of the study found four types of ectoparasites found in vannamei shrimp, namely Zoothanium sp., Epistylis sp., Carchesium sp., and Vorticella sp. The intensity of ectoparasite attack on shrimp was categorized as low to moderate infection, namely 4-7 individuals/shrimp. The prevalence rate is 80-100% with the category of moderate to very severe infection.Keywords:EctoparasitesPrevalenceIntensityVannamei shrimp

Abstract

Heavy metal pollution is one of the problems that often occurs in Indonesian coastal waters. Comparative methods of looking at heavy metal content in coastal sediments include a way to show similarities and differences between one or more articles by using certain criteria. Different comparison methods to see the heavy metal content in sediments include the AAS (Atomic Absorption Spectrophotometer) method, AAN (Netron Activation Analysis), Regression, and USEPA methods. Based on the comparison of 2 methods, namely: AAS and AAN methods, the most efficient in analyzing heavy metals in sediments in coastal areas is the Atomic Absorption Spectrophotometry (AAS) method compared to the Neutron Activation Analysis (AAS) method.Keywords:CoastalSedimentHeavy MetalSpectrophotometer
