Abstract

Perairan selatan Jawa merupakan bagian dari perairan samudera Hindia yang memiliki arus besar yang disebut Arus Khatulistiwa Selatan (AKS) yang sepanjang tahun menuju ke arah barat dan menyebar dari barat laut Australia menuju sisi lain dari samudera Hindia. Dinamika oseanografi perairan timur Samudera Hindia sangat dipengaruhi oleh keterkaitan yang kompleks. Penelitian ini bertujuan untuk menganalisis kondisi sebaran menegak dan melintang medan massa, tekanan dan arus geostropik perairan selatan Jawa. Penelitian ini menggunakan data World Ocean Atlas (WOA) hasil penginderaan jarak jauh bulan Agustus tahun 2009. Hasil penelitian yang diperoleh menunjukkan perairan selatan Jawa merupakan bagian dari perairan samudera Hindia yang memiliki arus besar yang disebut Arus Khatulistiwa Selatan (AKS) yang sepanjang tahun menuju ke arah barat dan menyebar dari barat laut Australia menuju sisi lain dari samudera Hindia. Apabila aliran AKS bergerak semakin cepat sepanjang pantai selatan Jawa-Sumbawa, maka akan mengakibatkan massa air akan menumpuk di belahan bumi selatan yang merupakan bagian sisi lepas pantai. Hal ini mengakibatkan bagian lepas pantai (yang menjauh dari pantai)  memiliki kedalaman dinamik yang lebih tinggi dari bagian yang lebih dekat atau berada di sisi pantai, sehingga arus geostropik yang mengalir pada wilayah tersebut akan mengalir dan dibelokan ke arah barat.

Abstract

The profile concentration of heavy metals, organic matter and the composition of the grain sizes is determined in two sediment cores from Karimata Strait. This study aimed to estimate the distribution of sediment grain sizes and distribution of heavy metals (Pb, Cu, Zn, Ni, As, and Fe) in three sediment fractions (>250 μm, 63-250 μm and <63 m) of Karimata Strait. Sampling was conducted using box core. Graining size analysis was carried out through sieving, continue with digestion, and analyze the heavy metals using Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES). Results of the study show that the sediment grain size distribution is strongly influenced by the water hydrodynamic condition (currents). It can be seen by the dominance of finding coarse grain size in the research areas. The highest concentration of the heavy metals was found in the finest grain size (<63 m) due to the larger surface area and higher adsorption capacity. Distribution of heavy metals Cu, Pb, Zn and Ni in the upper layer of sediments is higher than in the bottom layer. Furthermore, the As and Fe concentration in the surface were lower than in the bottom layer. Statistical analysis shows an association and a source of heavy metals mainly coming from the surrounding areas. It is supported by the enrichment factor values of finding heavy metals generally has been undergone enrichment.Keyword: Grain sizes,Heavy metals, ICP-OES,Karimata strait, Sediment

Abstract

The Western Pacific Equator waters are a meeting place for water masses coming from the Northern and Southern Hemispheres. This study aims to identify the characteristics of water masses formed in the waters of Northern Papua. The study of water mass characteristics in the northern waters of Papua was carried out based on reanalysis data from the World Ocean Atlas (WOA) in August 2018. There were 12 stations divided into 3 transects to be analyzed in this study, namely transect 1 and transect 2 which stretched north-south and transect 3 which stretches east-west. The analysis were performed by method of the core layer and was processed with Sofware Ocean Data View (ODV). The results showed in the waters of North Papua there was a meeting of 2 water masses from the North Pacific and South Pacific. The water masses characteristics in latitudes <5 oLU are affected by surface and intermediates of the South Pacific carried by the Papua New Guinea Coastal Current that flows along the northern coast of Papua New Guinea and into Papua waters and beyond into the waters of the Halmahera Sea. Whereas the mass of water in latitudes > 5 oLU is dominated by surface and intermediate water masses from the North Pacific carried by North Equatorial Counter Current.

Abstract

The issue of marine debris which is dominated by single-use plastic is one of the crucial problems that have the potential to cause various problems in the health of marine and coastal ecosystems, animals, to human health. During the pandemic, this problem continues to increase due to the environmentally unfriendly habits of the community and the lack of effective waste management. Socialization and virtual environmental campaigns are some of the most effective solutions that can increase public awareness in using plastic wisely during pandemic. This fieldwork practice aims to determine the stages of the environmental campaign activity "Plastic Free Parade" and the techniques of delivering materials in a virtual environmental campaign. The fieldwork practice is using a descriptive method that took place during the months of July - September 2020. Retrieval of data and information is obtained through assignments given by the executive director and field supervisor of Divers Clean Action. The practical results show that this activity was attended by 117 communities and 3600 viewers from all regions of Indonesia through zoom and YouTube applications. Various positive responses and commitments were given by the government, society, and other institutions regarding this activity

Abstract

Coral reefs are unique ecosystems and only occur in the tropics area. Diversity, distribution, and coral growth are influenced by environmental factors. Coral colonies morphologies or coral lifeform rates vary significantly between species and between environmental factors. This study aimed to determine the variations of hard coral based on their lifeform; and assess the condition of reefs by measuring the percent cover of live coral in the coastal area of Rendani Airport. Coral cover and coral damage data gathering used a survey approach with Point Intercept Transect (PIT) method. The results showed the variations of coral lifeform in the coastal area of Rendani was relatively low, as indicated by the absence of some coral lifeforms in the study site. The most variation lifeform was found at 7m depth with five lifeforms, while the lowest was found at 3m depth with three lifeforms. The live coral cover reached 77,66% at station 1 and 75,00% at station 2, and the lowest coverage was 11,33% at station 3. The highest average of rubble at station 1 at 4.33% and dead coral with algae was found to be highest at station 3 at 8.00%.

Abstract

Sponges are one of the most influential benthic organisms in coral reef ecosystems. Many studies on sponge communities have been carried out globally, from the tropics to the sub-tropics. However, in Indonesia, the sponge community has not been sufficiently observed, especially its diversity and interactions with habitats. Manokwari, a developing city north of the Bird's Head Seascape region, Papua has a lack of information on benthic communities and no reports of sponges. This study is to examine the sponge community (diversity and distribution) in coral reef ecosystem. This study found that sponge richness (species and morphology) was categorized as “low”, with only 11 species with 8 morphological forms. The most common species included Niphates erecta, Stylissa carteri, and Pseudoceratina purpurea, while the most common growth forms were massive and encrusting, accounting respectively for 27.3% and 18.2% of the total number of species. The highest diversity was found on the island of Kaki (5 species) with the island of Nusmapi having an uneven distribution of sponges. The results of our study found that there was no relationship between sponge diversity and morphology. This baseline information is essential for management of marine biodiversity hotspots in taking decisions for marine life conservation.  Spons merupakan salah satu organisme bentik yang paling berpengaruh dalam ekosistem terumbu karang. Banyak penelitian tentang komunitas spons telah dilakukan secara global, dari daerah tropis hingga sub tropis. Namun di Indonesia, komunitas spons belum cukup diamati, terutama keanekaragaman dan interaksinya dengan habitat. Manokwari, kota berkembang di utara dari wilayah Bentang Laut Kepala Burung (BLKB), Papua memiliki kekurangan informasi tentang komunitas bentik dan tidak ada laporan tentang spons. Studi ini untuk mengkaji komunitas spons (keanekaragaman dan distribusi) pada ekosistem terumbu karang. Penelitian ini menemukan kekayaan spons (spesies dan morfologi) yang dikategorikan “rendah”, dengan hanya 11 spesies dengan 8 bentuk morfologi. Spesies yang paling umum termasuk Niphates erecta, Stylissa carteri, dan Pseudoceratina purpurea, sedangkan bentuk pertumbuhan yang paling umum adalah massif dan encrusting dengan menyumbang masing-masing 27,3% dan18,2% dari total jumlah spesies. Keanekaragaman tertinggi ditemukan di pulau Kaki (5 spesies) dengan pulau Nusmapi memiliki sebaran spons tidak merata. Hasil penelitian kami menemukan tidak ada hubungan antara keanekaragaman spons dengan bentuk morfologi. Informasi dasar ini sangat penting untuk pengelolaan hotspot keanekaragaman hayati dalam perumusan keputusan untuk konservasi biota laut.

Abstract

Walking sharks are endemic to the New Guinea-Australian region, inhabiting shallow reef ecosystems. In Papuan waters there are four species of walking sharks, including Hemiscyllium galei. This research investigated ecological and biological aspects of H. galei in Doreri Bay near Manokwari, West Papua Province. The samples used in this study were collected from two locations in the waters of Doreri Bay, namely the islands of Arowi and Nusmapi between September and November 2020. This research was conducted using underwater visual census (UVC) during nighttime. Observations were made at two locations covering a total area 9,000 m2. A total of 10 individuals (7 males and 3 females) of H. galei were collected during the study. They were identified as distinct individuals based on spot shapes on the pectorals. All of them were then measured their morphometric parameters including total length, precaudal-fin length, head length, and body weight. After measurements were taken, all individual sharks were safely released back into their habitat. Morphometric measurements showed the total length of individual walking sharks obtained was no more than 75 cm for both male and female individuals. The abundance estimates of H. galei at Arowi and Nusmapi were 13,33 ind.ha-1 and 8,88 ind.ha-1 respectively. Analysis of length-weight relationship showed a negative allometric growth pattern, where body length growth was faster than weight gain.  Based on the present study, walking sharks probably occupies only a limited area in Doreri Bay, and are therefore very vulnerable to the daily activities of humans living in the vicinity.
