Abstract

ABSTRACTUtilization around of Belau Rivers was diverse, such as agriculture, industry, households, hotels, markets, residential population and fishing boats. According to the explanation, the purpose of this study was to determine distribution and concentration distribution patterns of Pb, Cd, and Cr which evaluated from the distribution of salinity, calculate the assimilation capacity in marine and analyzing the direction of environmental management Estuary Belau at Lampung Bay. The data was analyzed by using the view pattern of relationship between dissolved heavy metals and salinity through mixing graph approach. Furthermore, to know the pollutant load and capacity of assimilation were use a graph of the relationship between the concentration of each parameter with pollutant load on these parameters. The results analysis of pollutant loads and assimilation capacity showed that the parameters of TSS, BOD and COD were still able to perform self purification, whereas for the parameters of nitrate, phosphate, Pb, Cd and Cr were unable to perform self-purification. The management must be built not only within the autority of Lampung Government and the staffs, but also must be holistic upstream to downstream along the river that involves several government autority. Keywords: Pollution Load , heavy metals, the assimilation capacity, Estuary Belau

Abstract

Gastropods Conus spp. is a macrozoobenthic organism that is abundant in coastal waters and is consumed by coastal communities. Conus is a carnivorous organism that lives permanently at the bottom of the waters and has the property of accumulating pollutant materials such as pesticides, carbonates and heavy metals into the body's tissues through the food chain. The aim of this study was to identify the gastropods species Conus spp. from the Manokwari Coastal Waters. The available research method is quantitative descriptive research. The target species in this study were gastropods of the genus Conus spp. collected from the Manokwari Coastal Waters. A total of 27 individuals from 6 species of Conus spp. collected from 3 observation stations. Gastropods Conus spp. 6 species were found, namely: 1) Conus leopardus; 2) Conus imperialis; 3) Conus eburneus; 4) Conus virgo; 5) Conus planorbis, and 6) Conus lividus. The air quality parameters measured were within the appropriate range for the Gastropods Conus spp.

Abstract

Sedimentation adversely affects corals by impeding recruitment, hindering growth, and inducing stress, ultimately leading to degradation. This study aims to ascertain the correlation between sedimentation and coral cover. Five stations were sampled in Arfai waters in May 2023, with sedimentation rates measured using traps over 14 days. Coral reef conditions were assessed via the Point Intercept Transect (PIT) method, revealing a 'good' coral cover of 51%, dominated by Acropora submassive (ACS), Acropora branching (ACB), and Coral branching (CB). Sedimentation rates ranged from 6.26 to 33.92 mg/cm²/day, with impacts categorized from mild to moderate and moderate to heavy. Analysis confirms sedimentation's influence on coral reef life. Despite its significance for management strategies, long-term studies tracking coral reef structure and function in response to sediment influx are lacking. Further research on coral reef recovery post-sediment exposure is imperative.  Sedimentasi memengaruhi karang dengan menghambat rekruitmen, menghambat pertumbuhan, dan menyebabkan stres, yang akhirnya menyebabkan degradasi. Studi ini bertujuan untuk mengetahui hubungan antara sedimentasi dan tutupan karang. Lima stasiun diambil sampelnya di perairan Arfai pada Mei 2023, dengan tingkat sedimentasi diukur menggunakan perangkap selama 14 hari. Kondisi terumbu karang dinilai melalui metode Point Intercept Transect (PIT), yang mengungkapkan tutupan karang 'baik' sebesar 51%, didominasi oleh Acropora submassive (ACS), Acropora branching (ACB), dan Coral branching (CB). Tingkat sedimentasi berkisar dari 6,26 hingga 33,92 mg/cm²/hari, dengan dampak yang dikategorikan dari ringan hingga sedang dan sedang hingga berat. Analisis menegaskan pengaruh sedimentasi terhadap kehidupan terumbu karang. Meskipun penting untuk strategi pengelolaan, studi jangka panjang yang melacak struktur dan fungsi terumbu karang dalam menanggapi masukan sedimen masih kurang. Penelitian lebih lanjut tentang pemulihan terumbu karang setelah paparan sedimen sangat penting.

Abstract

ABSTRACT  The presence of coral reefs in coastal regions serves crucial ecological and economic functions, providing significant benefits for biodiversity and local communities reliant on these ecosystems for their livelihoods. Despite their importance, coral reefs face numerous threats stemming from both anthropogenic and natural activities. One viable restoration strategy to protect coral reef ecosystems in coastal areas is coral transplantation. This community service initiative aims to enhance understanding and awareness of the critical role of coral reef ecosystems while promoting their sustainability among the coastal communities of Arfai. The outreach program included two primary topics: coral reefs and the technique of coral transplantation. The session, lasting approximately 1.5 hours, featured a question-and-answer format to facilitate discussion and idea exchange. A demonstration of coral transplantation was conducted for residents of RT 001, utilizing the spider web method. Participants actively engaged in the transplantation process by tying seedlings and placing transplant racks in the waters surrounding Raimuti Arfai Island. Keywords: Arfai Coastal Communities; Coral Transplantation; Environmental Concern   ABSTRAK  Keberadaan terumbu karang pada wilayah pesisir memiliki fungsi dan manfaat penting secara ekologi dan  ekonomis bagi kehidupan biota dan bagi masyarakat pesisir dalam memenuhi kebutuhan hidup. Disamping potensi yang dimiliki, terumbu karang juga selalu mengalami ancaman dari berbagai aktivitas yang bersifat merusak baik akibat aktivitas antropogenik maupun alam. Salah satu upaya restorasi yang dapat dilakukan untuk menyelamatkan kehidupan terumbu karang di wilayah pesisir yaitu melalui tranplantasi karang. Tujuan kegiatan pengabdian ini adalah meningkatkan pemahaman dan kepedulian tentang pentingnya ekosistem terumbu karang dan turut menjaga kelestarian ekosistem terumbu karang kepada masyarakat pesisir Arfai. Dalam kegiatan penyuluhan terdapat 2 materi yang disampaikan yaitu tentang terumbu karang dan transplantasi karang. Kegiatan penyuluhan berlangsung selama kurang lebih 1,5 jam, dilakukan diskusi berupa tanya jawab atau saling bertukar pemikiran. Demonstrasi kegiatan transplantasi karang secara langsung kepada warga RT 001 tentang teknik transplantasi karang menggunakan metode jaring laba-laba (spider web). Warga turut dilibatkan dalam melakukan kegiatan transplantasi seperti pengikatan bibit, dan penempatan rak tranplantasi di perairan Pulau Raimuti Arfai.  Kata Kunci: Kepedulian Lingkungan; Masyarakat Pesisir Arfai; Transplantasi Karang

Abstract

ABSTRACT: The rabbitfish, Siganus canaliculatus is one of the components in the coastal waters ecosystem (mangrove, seagrass, and coral reef) and also has important economic value for coastal communities, but information is still limited, especially in Papuan waters. This study aims to analyze the size composition and growth patterns of rabbitfish (Siganus canaliculatus) based on habitat differences in the waters of Kwatisore, Yaur District, Nabire Regency. Sampling was carried out at three locations representing various habitat types, such as mangrove, seagrass, and coral reef. The data collected included the total length (mm) and body weight (g) of the fish, which were then analyzed using the length-weight relationship model W = aLb. The results showed that the average body length and average body weight were greater in the coral reef habitat type, but relatively the same among the three research locations. The overall growth pattern (habitat type and location) with a tendency for body length to increase faster than body weight (negative allometric pattern) with a b value ranging from 2.771 to 2.888. The size and growth patterns obtained in this study indicate connectivity between locations and habitats, although both habitat types show different roles in the life cycle of this fish. This study provides important information for ecosystem-based management of the rabbitfish resource in the coastal area of Nabire.
