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.

Sebagai salah satu negara kepulauan terbesar di dunia, garis pantai Indonesia menjadi garis pantai terpanjang nomor dua dan menjadikan wilayahnya sangat rentan terpapar berbagai dinamika perubahan lingkungan, seperti terjadinya abrasi yang disebabkan oleh faktor alam ataupun antropogenik. Aktivitas penambangan pasir laut menjadi salah satu kegiatan antropogenik yang berdampak besar terhadap fluktuasi di wilayah pesisir. Penambangan pasir laut merupakan proses ekstraksi pasir dari lingkungan laut yang dilakukan oleh sekelompok orang atau masyarakat dengan tujuan memanfaatkan sumber daya tersebut untuk kebutuhan material konstruksi, reklamasi lahan, kebutuhan industri, maupun permintaan ekspor. Kegiatan ini memicu dampak signifikan terhadap dinamika wilayah pesisir, terutama pada proses abrasi pantai. Artikel ini bertujuan untuk mengkaji dampak penambangan pasir laut terhadap perubahan garis pantai di Indonesia melalui pendekatan studi literatur. Hasil penelitian ini menjelaskan bahwa eksploitasi pasir laut secara berlebihan mengakibatkan kerusakan fisik ekosistem wilayah pesisir, termasuk tergerusnya wilayah pantai akibat abrasi, degradasi ekosistem terumbu karang, padang lamun, dan mangrove serta peningkatan risiko bencana seperti potensi bencana banjir dan tanah longsor. Lebih dari itu, kegiatan penambangan pasir laut juga diketahui memicu munculnya konflik sosial-ekonomi pada masyarakat. Artikel ini diharapkan dapat menjadi sumber informasi dalam merumuskan strategi perencanaan dan pengelolaan wilayah pesisir yang berkelanjutan dalam jangka panjang.

The coastal zone is a transitional area characterized by complex dynamics influenced by the interaction between land and sea. One of the consequences of this interaction is the accumulation of solid pollutants in the form of waste, which has the potential to disrupt the surrounding ecosystem's balance. This study aims to estimate the origin and movement pathways of marine debris along the coast of Sukajaya Lempasing Village by analyzing surface current patterns. The methods applied include purposive sampling and both quantitative and qualitative descriptive analysis. Waste data collection followed the guidelines issued by the Ministry of Marine Affairs and Fisheries in 2024, while surface current simulations were conducted using MIKE 21 with the Flow Model Flexible Mesh module. Monitoring results indicated that plastic waste dominated at all stations, with the highest number recorded at Station 1 (671 items), which also had the greatest total waste weight, amounting to 38.5 kg. The average waste density in the study area was 4.82 pcs/m². Surface current speeds ranged from 0.004 to 0.008 m/s on March 28, 2024, and from 0.005 to 0.015 m/s on April 2, 2024. Based on modeling results and interviews with local residents, the primary source of the waste was river discharge, which was then transported by longshore currents and subsequently accumulated along the coast of Sukajaya Lempasing Village.

The Cuku Nyinyi Mangrove Ecotourism Area in Sidodadi Village, Pesawaran Regency, Lampung has strong potential for marine ecotourism based on mangrove, seagrass, and coral reef ecosystems. However, increasing pressure from human activities and changing environmental conditions have led to the degradation of coral reefs, highlighting the need for rehabilitation efforts involving local communities. This community service program aimed to improve the knowledge and skills of ecotourism managers and local residents in coral reef transplantation using the spider-web method as an effort to support conservation and sustainable marine tourism development. The program was implemented through educational sessions on coral reefs, training in the use of diving equipment (SCUBA), construction of transplantation media, coral fragmentation, attachment of coral fragments to spider-web frames, and placement of the media on the seabed at a depth of approximately 5 meters. Activity data were collected through field observations, documentation, and informal discussions and interviews with participants. The results showed active community participation throughout all stages of the program and increased understanding of the importance of coral reef rehabilitation. The transplantation structures were successfully installed, and initial maintenance was carried out by removing algae to reduce competition with coral fragments. The main challenges included participants’ limited experience in using diving equipment and dynamic water conditions. Overall, this program had a positive impact on improving community capacity, strengthening conservation awareness, and supporting the development of educational tourism attractions in the Cuku Nyinyi Ecotourism Area.
