Abstract

The Halmahera Sea is one of the waters that has an important role for the development of Indonesia's climate. The waters of the Halmahera Sea are the ARLINDO route which is part of the global circulation flow. This study aimed to examine the horizontal and vertical temperature profiles, salinity density and T-S diagrams in the Halmahera Sea. The results showed that the horizontal and vertical profiles in the two seasons did not have a significant effect, this could be due to the movement of the New Guinea air mass along the coast of North Papua, then into the Halmahera Sea. T-chart showed the current moving in the Halmahera Sea vertically, including the SPSW or South Pacific Subtropical Water category, as evidenced by a salinity value of 34.7 PSU and a temperature value of 14oC at a depth of 500 m.

Abstract

Pollution is a threat to coral reefs in Indonesian waters. The number of coral reefs that are in very good condition denies very little compared to the total area of ??coral reefs in Indonesia. One form of pollution that can threaten coral reefs is marine debris. This study aims to identify potential sources of marine debris that can disrupt the health of coral reefs. the research was carried out in the waters of Kelapa Island, Kelapa Dua Island and Harapan Island, DKI Jakarta. The data used includes current data obtained using secondary data, data on the amount of marine debris,and the water base data substrate obtained using the LIT method. The results showed that the waste was thought to come from community activities, tourism and fisheries. The location that can be a source of marine debris in the research location comes from the mainland of Jakarta Bay. The bottom substrate conditions are in the "bad" to "medium" category. The range of the lowest proportion of live coral cover is 10,8% and the highest live coral cover at 31.1%. The coral reefs in the research location are in a state of worry and their existence is threatened by pollution of marine debris.

Abstract

Geological activity in the areas around the Sunda Strait has received attention through the tsunami that occurred at the end of 2018. Other activity was also recorded through a tectonic earthquake in the Sunda Strait subduction zone with Magnitude 6.9 on 2 August 2019. This condition raises concerns about the threat of an earthquake and tsunami disaster in surrounding area. Tanggamus Regency, which is located around the Sunda Strait, has a very wide tsunami-prone lowland, especially in the area at the tip of Semangka Bay. Based on these conditions, this study generally aims to map tsunami-prone areas, evacuation service areas for each Temporary Evacuation Place (TES), and analyze evacuation accessibility models. To answer these challenges, this research was conducted using Geographic Information systems (GIS) by following several methodological steps. Starting from determining the study area using spatial analysis, determining TES points, digitizing the road network and integrating it with Network Analysis tools on the ArcGIS platform, determining evacuation service areas, and modeling the travel time from each population residents to the nearest TES. Based on the results, it was found that some of the farthest areas were Semaka District, Wonosobo District and Kota Agung Barat District. The sub-district has a higher travel time to reach TES than the estimated arrival time of the tsunami.

Abstract

Marine debris atau sampah laut dapat didefinisikan sebagai bahan padat yang sengaja maupun tidak sengaja masuk ke lingkungan laut dengan cara dibuang secara langsung maupun tidak langsung dengan cara masuk dari arah daratan melalui sungai. Sampah laut memiliki dampak yang sangat luas, terutama pada ekosistem pesisir dan laut. Tidak sedikit biota laut yang dapat terjerat, terluka, atau bahkan menelan sampah laut. Melihat besarnya dampak yang ditimbulkan oleh sampah laut maka penyadaran masyarakat mengenai bahaya sampah laut sangat penting. Penyadaran masyarakat diperlukan untuk memberikan wawasan agar masyarakat lebih peduli terhadap lingkungan sekitarnya terutama pada wilayah ekosistem pesisir dan laut.Masyarakat Desa Way Lubuk yang berlokasi di kecamatan Kalianda memiliki potensi sumberdaya alam ekosistem pesisir dan laut yang cukup melimpah. Oleh karena itu, pengabdian masyarakat yang kami lakukan menggabungkan pengalaman dan pengetahuan di bidang marine debris sehingga diharapkan mampu memberikan dorongan bagi masyarakat untuk melakukan kegiatan coastal cleanup secara berkala dalam upaya mengurangi jumlah serta dampak sampah laut bagi ekosistem pesisir dan laut di wilayah Desa Way Lubuk.

Abstract

Dusun Kalangan Desa Pahawang memiliki potensi geografis wilayah darat dan laut dimana sebagian besar ekosistem daratan merupakan hutan dan daerah pantai terdapat hutan mangrove yang relatif masih baik. Namun, masyarakat belum banyak mengetahui manfaat dan fungsi dari ekosistem mangrove secara ekologis dan ekonomis. Sebagai wilayah pesisir Dusun Kalangan juga mengalami kejadian abrasi pantai dan juga banjir. Namun, masyarakat tidak mengetahui apa yang menjadi sebab dan solusi apa yang harus dilakukan. Melalui kegiatan pengabdian kepada masyarakat dusun kalangan ini telah dilakukan sebelumnya kunjungan kepada ketua dusun dan akan diambil langkah untuk memberikan 200 bibit tumbuhan mangrove dimana nantinya akan terlebih dahulu diberikan sosialisasi kemudian dilanjutkan dengan menanam massal bersama masyarakat bibit mangrove. Pengetahuan masyarakat yang masih minim terkait permasalahan banjir dan abrasi pantai merupakan salah satu kendala yang dapat diatasi dengan dilakukannya penyuluhan dan pelatihan bersama menanam bibit mangrove serta diskusi di lapang.

Abstract

HighlightMarine debris can be as a treat for coral reefBranching coral is the most affected by marine debrisPlastic marine debris commonly found in all research location, especially from fisheries and daily activityAbstractA coral reef is one of the important ecosystems, however, the existence of coral reef is threatened. Several factors can be a threat to the coral reef, such as marine debris. Research about marine debris on coral reefs in Indonesia has not much been done. This research aims to identify marine debris that is found and impacted, to identify the impacts caused, and to identify the life forms most susceptible to being affected. This research was conducted in Kelapa Island, Kelapa Dua Island, and Harapan Island by using the Belt Transect method sized 20 x 4 m2 with four repetitions at each station to determine coral reef life form, and type of marine  debris. The data was analyzed by using the Correspondence Analysis (CA) to determine the correlation of marine debris and the affected life forms of coral reefs. The result showed the plastic marine debris was found in all stations. Six life forms were affected by marine debris, and the most susceptible life forms that affected were massive and branching. The most dominant impact category on coral reefs was tissue loss with algal growth (TLAG).

Abstract

Highlight Research The very first attempt to investigated and revealing biodiversity of crustacean crab in coral reef ecosystem at Tidung Island, Indonesia Conservation area (Tidung Kecil) has more abundant crab species than tourism area (Tidung Besar). A microhabitat that suffers anthropogenic pressure may alter the composition of crustacean biodiversity, especially in crab group. Different characteristics and complexity of coral habitat affect the dynamics of cryptic crustacean communities   Abstract   Recent studies have been widely carried out on the important role and ecological function of coral reefs. However, little attention has been given to small and cryptic crustaceans organisms living within different microhabitat in dead corals. This study aimed to reveal the diversity of crustaceans that inhabit dead corals in Tidung Islands, Indonesia. A total of 134 individuals from 41 species in 13 families were recorded within eight dead corals taken from two different sites. Furthermore, the species identified from Tidung Kecil were significantly different and more diverse than Tidung Besar. It was suggested that differences in anthropogenic pressure between Tidung Besar and Kecil might have an important role in the spread of crab crustaceans' organisms. Xanthidae from infraorder Brachyura were observed to be the most dominant family, while Galatheidae and Porcellanidae from infraorder Anomura spread almost equally in both sites. Additionally, Psaumis cavipes and Chlorodiella nigra were species with the largest contribution of crab crustaceans' communities in the death of coral's ecosystem in the Tidung Islands. This result indicated that dead corals might play a key role in supporting and providing a habitat for crustacean cryptic.

Abstract

Kalangan Hamlet is one of the coastal communities in Pahawang Island Village, Lampung. It has abundant natural resources and offers prospects as a tourist destination. It is located away from Pahawang Island, so the area is considerably behind in terms of tourism management. The aim of the research was to develop effective strategies for managing the coastal areas of Kalangan Hamlet. The strategies had been suggested to contribute to Kalangan Hamlet's potential for coastal tourism growth. Data was collected using survey and observation methods, with respondents chosen through the snowball sampling technique. The collected data was analyzed using Strengths, Weakness, Opportunities, and Thread (SWOT) analysis and Analytic Hierarchy Process (AHP). The primary strategy for managing the coastal areas of Kalangan Hamlet involves enhancing infrastructure to support tourism, while simultaneously prioritizing the preservation of the natural ecosystem and ensuring the well-being of the local population. This approach balances economic development with environmental sustainability and social equity, thereby fostering a holistic and sustainable tourism model.

Abstract

The Java Sea is influenced by the west and east monsoons, which have an impact on hydrodynamic processes and chemical-biological water quality. Chemical-biological parameters play an important role in the food chain cycle that occurs in these waters. The quality of the eastern Java Sea waters is still limited by chemical-biological parameters, so the characteristics and distribution of these waters can be comprehensively known. chemical-biological. This study aimed to analyze the characteristics and distribution of nitrate, phosphate, oxygen, chlorophyll-A, and NPP parameters in the eastern Java Sea waters. This study used secondary data with daily temporal resolution from January to December 2020. Spatial analysis uses the climatological averaging method for 6 months as a statistical representative of the west monsoon and east monsoon. For each parameter, a vertical analysis was conducted to compare parameter values between the coastal waters of Tuban, Java Sea, and Banjarmasin Waters. Correlation analysis between parameters was conducted using the Pearson correlation method. Nitrate, phosphate, oxygen, chlorophyll-A, and NPP concentrations have temporal and spatial variability. Monsoon factors in Indonesia have a strong influence on the variability of nitrate, phosphate, oxygen, chlorophyll- A, and NPP concentrations. During the east monsoon, the concentration of chemical-biological parameters decreases, while in the west monsoon, the concentration increases and reaches its highest value. Generally, high concentrations occur in the northern and southern parts of the study site, around the coastal areas of Java and Kalimantan. Key Word: Chemical-Biological Parameters, Java Sea, Tuban Waters

Abstract

The mangrove ecosystem is a coastal ecosystem that is important for humans. Mangroves absorb carbon in the atmosphere and store it in biomass or sediment. So, in other words, mangroves play a significant role in mitigating global climate change. This study aimed to examine the structure of the mangrove ecosystem composition and estimate standing carbon stocks on Sangiang Island, Banten. The data taken was for the categories of trees, saplings, and seedlings (consisting of mangrove species, DBH, and height). The study was conducted at three stations with three replications for each station. The allometric formula obtained the estimated carbon stock from the stand biomass value. The results showed that 11 species of mangrove species were found with an average density of 1266 ind/ha (trees), 3733 ind/ha (saplings), and <70% (seedlings). Then the estimated average carbon stock in Sangiang Island, Banten is 271.29 tons/ha.
