Marine Debris

Marine debris is a waste product found in the sea, whether intentionally disposed of or not. This type of plastic waste is the most commonly found in the sea.Plastic waste that found in the ocean will degrade into micro-plastics. Micro-plastics can cause harm to marine organisms and even reach humans through food chain events. In order to reduce the dangers and impacts, it is necessary to introduce the management of coastal areas as part of the ecosystem, through socialization activities to coastal communities. The results of the activities showed interest and positive responses from the community. In addition, the knowledge about the concepts of marine debris, micro-plastics and ecosystems and their relationships has also increased by i.e., of 76%.

Plastic waste will degrade in the water and will break down into small particles called microplastics. Microplastics have a shape similar to food sources for marine organisms such as plankton, where if these microplastics are accidentally ingested by marine organisms it will enter the food chain and end up in humans through bioaccumulation and biomagnification. Plankton are divided into two types, namely phytoplankton as the main water producer and zooplankton as the second energy level that connects major producers with consumers at a higher level of food. This research was conducted to determine the type and ratio of the amount of microplastic and plankton as a source of food for marine organisms. This research was conducted in the waters of Benoa Bay, which is a semi-closed water area and has a variety of activities and there are also two large rivers that can contribute to pollution waste in the waters of Benoa Bay, this can lead to competition between the amount of plastic and plankton as the main producer in food chain. This research was conducted from February to July 2020 and sample analysis was carried out at the Marine Science Laboratory, Faculty of Marine and Fisheries Sciences, Udayana University. Sampling is done by pulling the trawl horizontally with a distance of 500 meters and a constant boat speed of 5 km/hour. The composition of the types of microplastics found were film, fragment, foam and fiber. The highest composition of phytoplankton comes from the Bacillariophyceae class, while the highest composition of zooplankton comes from the Malacostraca class. The average total abundance of microplastics is 1.69 particles/m3, while the average total abundance of plankton is 2851 Ind/m3 and a ratio of 1:1687. This result shows that until now the abundance of plankton is still much greater than the abundance of microplastics in the waters. However, considering the high amount of plastic use from household and tourism activities, it can also increase the inclusion of plastic waste that will enter the ocean.

<p><strong>Abstract</strong>: Changes in the global oceanic system have already negatively affected the world’s marine life and the livelihoods of many coastal communities across the world, including in the Middle East' and Eastern Africa's Least Developed Countries (LDCs). Coastal communities in Somalia and Yemen for instance, have been particularly affected by extreme environmental events (EEEs), with an increase in the frequency of tropical cyclones over the past 20 years. Using expert elicitation as a method to generate data to assess and quantify a specific issue in the absence of sufficient and/or reliable data, the authors interviewed selected specialists in or from Somalia and Yemen, from diverse fields of expertise related to climate change, extreme environmental events, disaster risk reduction, and humanitarian affairs. Ten experts followed the elicitation protocol and answered a specific series of questions in order to better quantify the expectable mid-to-long-term climatic and humanitarian levels of risks, impacts, and consequences that climate change and related issues (e.g., sea-level rise, tropical cyclones, and sea surge) may generate in coastal areas along the Gulf of Aden's coastal cities of Aden and Bossaso, in Yemen and Somalia, respectively.</p><p>The findings indicate that there is cause for significant concern as climate change is assessed by all interviewees - irrespective of their background -, as very likely to hold a negative to a devastating impact on (fresh) water security, food security, public health, social conflicts, population displacement, and eventually political stability; and to strongly worsen the humanitarian situations in Somalia and Yemen, both in the medium-term (i.e., 2020-2050) and the long-term (i.e., 2020-2100). The authors call on the scientific community to further research the issue of climate change in the understudied coastal areas of the Gulf of Aden, and on the international community to pro-actively and urgently help the local populations and relevant authorities to rapidly and strongly build up their adaptation capacities, especially in the niche of coastal EEEs.</p>

Sepuluh tahun yang lalu putusan Mahkamah Konstitusi Nomor 3/PUU-VIII/2010 telah menegaskan bahwa  bahwa pemberian hak pengusahaan perairan pesisir (HP3) oleh pemerintah kepada pihak swasta bertentangan dengan konstitusi, terutama dengan Pasal 33 ayat (4) UUD 1945. Pembentuk undang-undang kemudian merespon putusan tersebut dengan merevisi UU Nomor 27 Tahun 2007 menjadi Undang-Undang Nomor 1 Tahun 2014 tentang Perubahan Atas Undang-Undang Nomor 27 Tahun 2007 tentang Pengelolaan Wilayah Pesisir dan Pulau-Pulau Kecil. Revisi tersebut telah mengubah Rezim HP3 dari UU 27/2007 menjadi rezim perizinan dalam UU 1/2014. Sayangnya, perubahan tersebut justru menimbulkan berbagai persoalan mulai dari konflik antara undang-undang serta peraturan dibawah undang-undang yang pada akhirnya sangat berpotensi merugikan hak-hak konstitusional masyarakat pesisir pantai. Penelitian ini memfokuskan pada aspek yuridis maupun sosiologis terkait perlindungan hak-hak konstitusional masyarakat pesisir pantai setelah Putusan Mahkamah Konstitusi Nomor 3/PUU-VIII/2010. Penelitian ini secara mendalam membahas mengenai tindaklanjut putusan MK a quo oleh pembentuk undang-undang, pemerintah pusat hingga pemerintah daerah dan stakeholder serta pemenuhan hak-hak konstitusional masyarakat pesisir pantai. Penelitian ini merupakan penelitian hukum normatif dengan cara meneliti Putusan MK Nomor 3/PUU-VIII/2010. Pembahasan secara deskriptif digunakan untuk memahami politik hukum pengelolaan wilayah pesisir sebagai upaya memenuhi hak-hak konstitusional masyarakat pesisir pantai. Disamping itu, Pengelolaan wilayah pesisir secara terpadu yang merupakan proses yang dinamis, multidisiplin, dan berulang untuk mempromosikan pengelolaan kawasan pesisir yang berkelanjutan. Termasuk seluruh siklus pengumpulan informasi, perencanaan, pengambilan keputusan, manajemen dan pemantauan implementasi. Ten years ago, the Constitutional Court Decision Number 3/PUU-VIII/2010 confirmed that the granting of concession rights for coastal waters (after this: HP3) by the government to private parties was contrary against the constitution, especially Article 33 paragraph (4) of the 1945 Constitution. Legislators then respond to the decision to revise Law No. 27 of 2007 as Law No. 1 of 2014 on the Amendment of Law No. 27 of 2007 on the Management of Coastal Areas and Small Islands. The revision has changed the HP3 regime from Law 27/2007 to the licensing regime in Law 1/2014. Unfortunately, these changes would lead to various juridical problems ranging from conflict between the laws and regulations under legislation that ultimately is potentially detrimental to the constitutional rights of coastal communities. This research focuses on juridical and sociological aspects related to the coastal communities protection of constitutional rights after the Constitutional Court Decision Number 3/PUU-VIII/2010. This research in-depth discusses the follow-up of the Constitutional Court decision a quo by legislators, central government, local governments, stakeholders, and the fulfilment of the constitutional rights of coastal communities. This research is normative legal research by examining the Constitutional Court decision Number 3/PUU-VIII/2010. The descriptive discussion used to understand coastal zone management law's politics to fulfil the constitutional rights of coastal communities. Besides, integrated coastal zone management (Integrated Coastal Zone Management) is a dynamic process, multidisciplinary, and repeated to promote sustainable coastal areas' sustainable management. It includes the whole cycle of information collection, planning, decision-making, management, and implementation monitoring.

PLASTICS POLLUTION IN THE SEA. Indonesia is considered as the second biggest plastic waste producer in the sea. Information on waste pollution and its impact on marine organisms in Indonesia is still limited. Waste disposal and solid waste (plastics) into the sea are continuously occuring; elevating the thoughts of global impact of plastic waste contamination. Increased use of plastic is a consequence of the development of technologies, industries and also the population. This paper is expected to provide knowledge and information of plastics that exist in the sea, especially Indonesian Sea.

Microplastic research is currently an exciting trend along with global environmental problems. The purpose of this study is to review the development of microplastic research in ASEAN. The researc uses a systematic review method by searching for the keyword “microplastic” and the name of the ASEAN country on the Google Scholar website, Science Direct, and other research paper provider websites. Papers reviewed in 2018 to August 2021 period were then classified based on the components analyzed. The results showed that based on the research location category, the majority of microplastic research was carried out in Vietnam (12/50 articles). The category of research object focused on marine organisms more than terrestrial organisms, the category of microplastic concentration varied because the microplastic sampling method was not standardized, the category of microplastic form dominated by the form of fiber; commonly found in coastal areas. The socio-economic category is not much related to the circular economy. To conclude, microplastic research still has opportunities, especially from a socio-economic perspective.

Human pressure on the coastal and aquatic surrounding ecosystem in Indonesia, through plastic waste, is increasing, considering that 60 % of the approximately 250 million people live in the coastal areas. Plastic waste originating from human activities has become a massive problem in almost all the small island and coastal regions, especially in the eastern part of Indonesia. This condition is caused by poor waste management and a lack of public awareness in disposing of waste in its place, including in an area known as its marine biodiversities and marine tourism spots like Masohi in Central Maluku. Also, the composition of waste is dominated by plastic waste that cannot be decomposed in a short period, continue circulated on the ocean currents, and will be deposited in coastal areas. Furthermore, some plastic waste will break down into micro-plastics that pollute not only the environment but also marine biota, which are often consumed by humans. This situation profoundly affects the sustainability and function of aquaecosystem services in coastal areas. Therefore, a comprehensive policy and regulation, and interdisciplinary study for analysing vulnerable coastal ecosystem, and mitigating the potential risk of plastic pollution in Masohi, Central Maluku are essential to be conducted.

Marine debris is a major challenge threatening ocean and coastal environment with no easy solution in coming years. The problem is totally manmade and extendeds to coastal areas around the world. The accumulation of marine debris is largely due to lack of awareness and environmental education among the public reinforced with mismanagement of municipal litter in coastal cities. Iran has about 2415 km of coastlines in the north and south of the country that suffer severely from a marine debris problem. Despite the great scale of the problem that leads to the shutdown of some beaches to beachgoers, there are no documented data on the abundance, composition and sources of marine debris dispersed on beaches. With the cooperation of marine biology student volunteers, we surveyed beaches at two scales, 100 m and 1 km searching for litter in varying ranges. The results revealed that the most common items are made of plastic/polystyrene. Tourism and recreational activities are responsible for more than 90% of litter production on the study beach. Fisheries and aquaculture are the second source of most abundant marine litter found on the beach with considerable distance from tourism activities. We conclude that lack of education about the consequences of marine litter is the main reason for marine debris at the study beach. Another reason is related to rapid construction of coastal areas and development of coastal cities with no proper infrastructure to manage municipal littering.
