Abstract

Blue swimming crab (BSC) is a fishery commodity with high economic value and great demand in domestic and foreign markets. P. pelagicus swimming crabs are commonly found in Indonesian sea waters, one of the largest contributors to the country's foreign exchange after shrimp and tuna. The high demand for blue crab resources will trigger an increase in fishing efforts. If this is done continuously, it is feared that it could endanger the population structure. Moreover, disrupting the sustainability of blue swimming crab resources in the waters, this study examines the morphometric distribution and growth pattern of P. pelagicus crabs based on environmental characteristics in Candi waters, Pamekasaan Regency. Census sampling was carried out using the census method; the census method was carried out by taking all crab samples caught by fishermen. The results obtained found 33 individual crabs, which were divided into three classes, namely small (<10 cm), medium (>10 cm), and large (>12 cm) size classes. Male crabs dominated the research locations with wider straps than female crabs. The analysis results show that the width-weight relationship's b values are 1.47 (males) and 2.00 (females). In addition, male and female crabs have a positive allometric growth pattern. Blue swimming crabs are often found in habitats with a substrate of dusty mud, high salinity and organic matter.

Abstract

Phytoplankton have important as food-chain major component and primary production of marine environment. However, high abundance of phytoplankton could give harmful effects toward water ecosystem. Moreover, they could produce toxic substances that will be accumulated within their consumer. This accumulation could be dangerous for human or animals.This research were aimed to determine and calculatespecies of harmful algae in Banyuasin coastal waters. The study was conducted on April, June, August, October and December of 2013, and in February 2014, at ten stations. Phytoplankton samples were taken vertically using plankton nets. In the form of cone-shaped with a diameter of 30 cm, length 100 cm and mesh size 30 μm.The result showed that there are 35 genera of phytoplankton. That have been found and consisted of four groups; Bacillariophyceae, Dinophyceae, Cyanophyceae and Chlorophyceae. 13 species were identified as Harmful Algal (Chaetoceros, Coscinodiscus, Nitzschia, Skeletonema, Thalassiosira, Alexandrium, Ceratium, Dinophysis, Noctiluca, Protoperidinium, Prorocentrum, Anabaena dan Oscillatoria), with seven of them were known for having toxin (Nitzschia, Alexandrium, Dinophysis, Protoperidinium Prorocentrum, Anabaena and Oscillatoria). Monitoring result showed that the highest number of species of potential harmful algal blooms (HABs) occured in June and the highest abundance occured in August, especially Chaetoceros and Skeletonema.How to CiteAryawati, R., Bengen, D.

Abstract

The Garapan river mouth forms part of the Tanjung Pasir coastal area. This region receives materials not only from coastal waters but also from domestic sewage and industrial wastewater that contains heavy metals such as Cu, Pb, and Zn. On the contrary, the Cibungur river mouth in the different coastal area, receives relatively lower amounts of domestic sewage and industrial wastewater. The objective of this study was to determine the Cu, Pb, and Zn content in the coastal sediment as well as the levels of A.indica and their relationship with water quality parameters. Samples were collected from four stations located in the Garapan and Cibungur river mouths and were analyzed for metal content using atomic absorption spectrometry Shimadzu 6300. Samples of A. indica found in the field are categorized into three diferent size classes. It is because size related to heavy metal accumulation. Results showed that bioconcentration factor (BCF) values were Zn>Cu>Pb in both locations. Small size A. indica tends to have higher values of BCF for Cu and Zn compared to medium and larger sized samples. Furthermore, the BCF values of Cu, Pb, and Zn in A. indica were higher when the sediment had a lower concentration of organic matter.

Abstract

Tantangan pengembangan pariwisata di kawasan konservasi muncul ketika kepentingan pembangunan ekonomi tidak selaras dengan pembangunan ekologi. Raja Ampat memiliki keanekaragaman hayati yang perlu dilindungi. Di sisi lain, keanekaragaman hayati tersebut menjadi potensi wisata yang dimanfaatkan untuk kepentingan ekonomi. Pemerintah Kabupaten Raja Ampat menetapkan Kawasan Perairan Raja Ampat sebagai zona semiintensif, yakni kawasan yang dirancang untuk menerima kunjungan wisatawan dalam skala kecil dengan aktivitas wisata yang terbatas. Kolaborasi antarpemangku kepentingan dalam pemanfaatan potensi wisata diperlukan untuk menghindari berbagai konflik kepentingan. Penelitian ini bertujuan untuk menguraikan mekanisme dan hubungan dinamis yang kompleks antarpemangku kepentingan dan mengungkapkan kunci keberhasilan pengelolaan kolaborasi ekowisata di kawasan konservasi. Penelitian ini menggunakan pendekatan kualitatif dengan metode studi kasus. Penelitian dilakukan di Kampung Wisata Arborek, Yenbuba dan Sawinggrai Kabupaten Raja Ampat pada bulan Oktober 2020. Pengumpulan data diperoleh melalui wawancara mendalam, observasi partisipatif dan focus group discussion. Hasil penelitian menunjukkan bahwa mekanisme pengelolaan kolaborasi dilakukan melalui sinergi peran antara pemerintah, masyarakat, LSM, akademisi, dan swasta mulai dari tahap perencanaan, pelaksanaan, hingga pengawasan dengan tipe konsultatif. Tipe konsultatif ini ditandai dengan adanya mekanisme dialog antara pemerintah dan masyarakat, tetapi pengambilan keputusan masih dilakukan oleh pemerintah. Kunci keberhasilan pengelolaan kolaborasi ekowisata di kawasan konservasi meliputi (1) koordinasi antarpemangku kepentingan; (2) keterlibatan masyarakat lokal; (3) kesadaran dan komitmen bersama; (4) aturan pengelolaan disepakati bersama; (5) pembentukan kebijakan sesuai dengan kondisi lokal; (6) adanya pembagian kekuasaan dan tanggung jawab; (7) adanya mekanisme penyelesaian konflik; dan (8) berlakunya sanksi. Title: Mechanism and Keys to Successful Collaboration Management of Marine Ecotourism in The Raja Ampat Conservation Area   The challenge of developing tourism in conservation area arises when the interests of economic development are not aligned with ecological development. Raja Ampat has a biodiversity that needs to be protected. On the other hand, this biodiversity is a tourism potential utilized for economic interests. The Raja Ampat Regency Government has designated the Raja Ampat Waters Area as a semi-intensive zone, namely an area designed to receive tourist visits on a smaller scale with limited tourist activities. Collaboration among stakeholders in utilizing tourism potential is required to avoid various conflicts of interest. This research aims to elucidated complex dynamic mechanisms and relationships between stakeholders and revealed the keys to successful collaborative ecotourism management in conservation areas. This research used a qualitative approach with a case study method. Research was conducted in Arborek, Yenbuba, and Sawinggrai Tourism Villages, Raja Ampat Regency in October 2020. Data was collected through in-depth interviews, participatory observation, and focus group discussion. The study results showed that the mechanism collaborative management was carried out through the synergy of multi-party, namely government, communities, NGOs, academics, and the private sector, by forming a collaborative management strategy from planning to monitoring with a consultative type. This consultative type is characterized by the existence of a dialogue mechanism between the government and the community, but decision making is still carried out by the government. The keys to successful collaborative management of ecotourism in conservation areas include (1) coordination between stakeholders; (2) involvement of local communities; (3) awareness and commitment among stakeholders; (4) mutually agreed management rules; (5) local based policies and regulations; (6) a division of power and responsibility; (7) a conflict resolution mechanism; and (8) sanctions apply.

Abstract

Understanding the influence and impact of environmental factors on manta ray sightings is critical to understanding the spatial and temporal ecology of a highly mobile species. Therefore, this study aims to determine the influence and impact of environmental factors as indicated by the parameters of wind speed, chlorophyll-a, SST, salinity, pH, dissolved oxygen, and the number of phytoplankton and zooplankton species. The mapped chlorophyll-a was re-analyzed based on the seasonal period throughout 2021 downloaded from marine copernicus and analyzed by kriging method. The influence and effects of environmental parameters on the short-term appearance of eye rays were studied using an adaptive model (GAM). The analysis showed a significant influence of environmental factors on manta ray sightings in Raja Ampat, namely Calanoid spp, Oithona nana, Acartia clausi, Calanus helgoladicus, and Oithona brevicornis. Based on this model, zooplankton is an important parameter that can describe the influence of environmental parameters on manta ray sightings at observation points in Raja Ampat MPA. The results of the reanalysis of chlorophyll-a concentrations were highest in the eastern to transitional seasons, which were scattered on the west side of Raja Ampat waters. Meanwhile, chlorophyll-a concentrations were low in the west to transitional season on the east side. This mechanism may drive the foraging strategy of manta rays, which visit shallow waters where zooplankton density and biomass are abundant. Adopting the BHS MPA network concept, as it has been implemented, would be in line with broader conservation expectations for the sustainability of manta rays in Raja Ampat.

Abstract

Coral animals have tentacles in which there are Nematocysts in the ectoderm layer and zooxanthella in the endoderm layer, and these two components have a role as a defense and food source; this study was conducted to identify the components of Montipora danae coral tentacles. The research was conducted in Marak Island, West Sumatra, with a purposive sampling method based on the presence of M.danae. The coral samples were decalcified to separate the tissue from the skeleton. The results of this study indicate that M.danae consists of Nematocysts type sH (small Holotrich), MpM-I (Microbasic p-Mastighopore I), and H (Holotrich). Holotrich has the highest relative abundance of 74-91%, MpM-I has 3,92-20,63% and sH has 3-24%. Holotrich has larger morphometrics than sH and MpM-I, namely 72,76-82,35 μm capsule length and 19,55-24 μm capsule width. The zooxanthella density of M. danae was lower than that of normal corals at 624 cells/cm2

Abstract

The waters of Madong in Tanjung Pinang city are located in a strategic area that has a significant impact on the livelihoods of fishermen, post-bauxite mining areas, ship traffic, and population activities. These factors have contributed to the contamination of heavy metal Pb in the waters, sediments, and dog conch. The purpose of this study is to analyze the levels of heavy metal Pb in the waters, sediment, and dog conch, and to assess the bioaccumulation factors of heavy metal Pb in dog conch in Madong waters. Samples of waters, sediment, and dog conch were collected from three stations and analyzed using AAS at the Marine Chemistry Laboratory of Raja Ali Haji Maritime University. The concentration of Pb in the waters ranged from 0.0204 mg/L to 0.0636 mg/L, while the concentration of Pb in sediment ranged from 0.5947 mg/Kg to 0.9402 mg/Kg. The Pb metal concentration in juvenile dog conch ranged from 0.0745 mg/Kg to 0.3437 mg/Kg. The highest BAF and BSAF values for Pb metal in adult dog conch were observed at station 1, with values of 27.241 and 0.6991, respectively. The categorization of Pb metal in Strombus canarium dog conch as low is based on the BAF and BSAF value categories.

Abstract

An integrated institutional approach is expected to be a solution to overcome this policy fragmentation. With integrated mangrove management across jurisdictions, it can be clearer to maintain the sustainability of the mangrove ecosystem while supporting sustainable development in the coastal area of Jakarta Bay. This study aims to develop an ideal inter-jurisdictional institutional framework for mangrove management in Jakarta Bay. The study used primary and secondary data. Data analysis uses stakeholder analysis, multidimensional scaling (MDS), and interpretive structural modeling (ISM). The results of the stakeholder classification showed that local communities occupy the subject category, the key players are the central government and regional governments, universities and NGOs occupy the context setter position, and the crowded category is the private sector. The results of the MDS analysis using RAP Mangrove show a sustainability index value for the institutional dimension of 11.59%. The institutional design of the three elements, which are divided into 11 sub-elements, shows that the availability of adequate data and planning for the implementation of mangrove rehabilitation, restoring mangrove ecosystems in damaged conditions, improving the quality of degraded mangrove cover and ponds, and mangrove rehabilitation at the multi-strata government policy and program level (multi-related sectors, regional government, and village government) are the basis for the achievement of the other sub-elements. Synchronization of regulations and policies across sectors, as well as active participation from various stakeholders, are the keys to success in maintaining the sustainability of mangrove ecosystems.

Abstract

Biodiversity assessment surveys are necessary for establishing conservation areas. However, such surveys are typically expensive, primarily if they cover a large area and take a long time. The survey difficulty increases when applied to cryptic, sparse, and fast-moving organisms. In addition, it requires expertise in taxonomic-biota classification. The breakthrough environmental DNA (eDNA) metabarcoding technique promises to overcome all the hurdles of assessing the potential for marine biodiversity in a non-invasive, rapid, extensive, and more effective way. We evaluated the ability of the eDNA survey to reveal the potential diversity and character of marine eukaryotes in the Lombok Island Marine Protected Area. A sampling of seawater and sediment eDNA in pore size fractions of 0.4-12 ?m and >12 ?m was carried out in the Core Zone, Non-Core Zone, and Non-Conservation Area, in east, north, and west Lombok, respectively. The detection and classification of eukaryotes using bioinformatics analysis were accomplished following extraction, amplification, and DNA sequencing. We identified 20,478 unique sequences of potential species classified in five kingdoms to 654 marine eukaryotes families. The comparison results show differences in community structure between locations, as well as differences in diversity between media and factions. The eDNA survey can assess marine biodiversity at a macro level and has implications for management in conservation areas.Keywords: Biodiversity, Marine eukaryotes, environmental DNA, the Primary V9-SSU 18S rRNA gene
