However, only few studies use multi-scale accuracy methods to estimate the loss of hard corals in Kapoposang Marine Tourism Park. Hence, this study aims to map and analyze the dynamics of coral reef covers in Kapoposang Marine Tourism Park of Spermonde Islands for the past two decades (from 2000 to 2019). Data was obtained from the coral reef survey, to validate the Landsat imageries (TM dan ETM+), which were acquired and selected based on similar tides conditions. Gap fills on Landsat ETM+ are managed using Frame and Fill software, then analyzed using Lyzenga algorithm and validated with ground truth data. This study reveals that the coral reef coverage in Kapoposang Marine Tourism Park increased about 9,61% from 2000 to 2015, then declined about 7,41% from 2015 to 2019.

Banten Province coastal region was directly affected by the tsunami waves last December 2018 due to the Anak Krakatau Volcano’s activities, covering Pandeglang and Serang Regencies. Regional and spatial planning in a coastal buffer zone is mandated by laws and regulations, both central and local, but still sometimes neglected. The spatial analysis was carried out by identifying land use/cover in Banten Province coastal area using high and medium resolution images acquired from the Google Earth website. The results of the land use/cover map observations, which validated with field data, showed that the built-up area from the tourism sector in the form of buildings, facilities, and infrastructures dominate the coastal buffer zone, both in Pandeglang and Serang Regencies, especially in Anyer District (22.3 ha), Carita District (10.7 ha), and Cinangka District (7.2 ha). Moreover,...

The existence of these offices requires a mobilization for employees who are generally in the neighboring area of Jakarta. Land transportation is an option that is widely used as a means of mobilization. This paper will present the results of a study on the effects of implementing Large-Scale Social Restrictions starting in April 2020 to prevent the spread of the Covid-19 disease. Through a questionnaire distributed to pickup drivers, employees of the Ministry of Marine Affairs and Fisheries in Ancol, North Jakarta. The result is that PSBB has brought positive and negative impacts on land transportation travel.

It designated as a conservation area by the decision of Berau District Head No. 516 of 2013 concerning the Reservation of Coastal Conservation Areas and Small Islands. Derawan Island, also known as the National Tourism Destination (DPN) based on its coral reefs diversity that considered adjacent to the Coral Triangle Initiative (CTI). The increase of Tourist visits to Derawan Islands since 2000, which affected land cover changes in Derawan Island coast such as for lodging, jetty and other infrastructure. Changes in land cover together with natural coastal processes causing abrasion in the west, and east sides, while accretion in the southeast side of the island. Land cover change especially built-up area from 2003 to 2018 is 6.25% per year. Observations and analyzes using DSAS (Digital Coastline Analysis System) conducted in...

Kawasan ini dinilai terbaik di dunia dengan sering dijadikan sebagai ajang diving dan snorkling bagi para penyelam nasional maupun internasional. Penelitian ini bertujuan untuk menentukan kesesuaian kawasan untuk wisata bahari menggunakan SIG. Metode yang digunakan dalam penelitian ini adalah metode analisis spasial (keruangan) dan analisa tabular terhadap kesesuaian kawasan dalam SIG. Hasil analisis spasial dan tabular terhadap kesesuaian kawasan untuk wisata bahari, menunjukkan bahwa lokasi yang sesuai adalah di utara Pulau Wangi-wangi, Kecamatan Wangi-wangi dan di utara Pulau Kapota, Kecamatan Wangi-wangi Selatan dengan luas sekitar 2.786,9 hektar atau 20,3% dari luas total wilayah kawasan

Jumlah wisatawan terus bertambah untuk menikmati keindahan alamnya. Wisatawan yang terus bertambah tersebut dapat berdampak buruk terhadap lingkungan di daerah wisata, salah satunya adalah kualitas air di bawah tanah yang biasa digunakan untuk keperluan masyarakat sehari-hari. Penelitian ini bertujuan untuk meneliti kualitas lingkungan pesisir Kecamatan Karimunjawa yang meliputi air tanah di Kecamatan Karimunjawa terhadap kemungkinan pencemaran akibat aktivitas manusia. Metode yang digunakan adalah studi literatur, survei, dan analisis hasil survei. Survei yang dilakukan meliputi survei sampling air tanah dan wawancara dengan narasumber. Data primer yang diperoleh di lapangan dilengkapi data sekunder selanjutnya diolah dan dianalisis sehingga diperoleh informasi mengenai indikasi adanya pencem...

Each sea has significantly different characteristics.<br> The Timor Sea is a deep-sea habitat with depths of more than 2000 m, whereas<br> the Arafura Sea is a shallow sea of less than 60 m depth. The circulation of the<br> Arafura and Timor Seas, particularly at the surface, is affected by the monsoon<br> wind pattern. The changes of wind strength and direction that blow on the sea<br> surface produce changes in water dynamics. According to Clark et al. (1999),<br> strengthening of the monsoon wind will result in increased Ekman transport,<br> vertical mixing and greater heat loss due to evaporation during summer, causing a<br> decrease in sea surface temperatures. However, during weak wind, the vertical<br> mixing of water masses is weak, causing less heat loss through evaporation. The<br> latter condition caus...

Teluk sebagai suatu estuaria tertutup memiliki peran strategis sebagai salah satu sumberdaya ekologi dan layanan lingkungan. Paper ini mencoba menyajikan kriteria penentuan teluk menurut UNCLOS, dengan aplikasi langsung untuk wilayah Bungus Teluk Kabung-Kota Padang. Menurut UNCLOS definisi teluk adalah bentukan laut yang menjorok ke arah daratan dengan luas area yang lebih besar daripada luasan setengah lingkaran berdiameter mulut lekukan di teluk tersebut. Hasil menunjukkan bahwa peta RBI produk dari Bakosurtanal belum sepenuhnya mengacu pada kriteria teluk yang disyaratkan oleh UNCLOS. Kata Kunci: UNCLOS, kategori teluk, konvensi hukum laut ABSTRACT Indonesia as an archipelagic country has many bays. As an enclosed estuary, a bay area has strategic role as a source of ecological resources and other environmental services. This paper triesto present a criteria to consider an area as abay under UNCLOS, with direct...
