NOC is generated by the interaction of wind stress and the North Natuna Sea’s bottom topography. The purposes of the present study is to investigate the vertical variability of NOC and its relation to El Niňo Southern Oscillation (ENSO) using Marine Copernicus reanalysis data. The vertical variability refers to the spatial distribution of NOC pattern at the surface layer, thermocline layer, and deep/bottom layer. in 2014 as representative of normal ENSO condition. -
Ocean Wave Characteristics in Indonesian Waters for Sea Transportation Safety and Planning
IPTEK, The Journal for Technology and Science, Vol. 26, No. 1, April 2015 19 Ocean Wave Characteristics in Indonesian Waters for Sea Transportation Safety and Planning Roni Kurniawan1 and Mia Khusnul Khotimah2 AbstractThis study was aimed to learn about ocean wave characteristics and to identify times and areas with vulnerability to high waves in Indonesian waters. Significant wave height of Windwaves-05 model output was used to obtain such information, with surface level wind data for 11 years period (2000 to 2010) from NCEP-NOAA as the input. The model output data was then validated using multimission satellite altimeter data obtained from Aviso. Further, the data were used to identify areas of high waves based on the high wave’s classification by WMO. From all of the processing results, the wave characteristics in Indonesian waters were identified, especially on ALKI (Indonesian Archipelagic Sea Lanes). Along with it, which lanes that have high potential for dangerous waves and when it occurred were identified as well. The study concluded that throughout the years, Windwaves-05 model had a magnificent performance in providing ocean wave characteristics information in Indonesian waters. The information of height wave vulnerability needed to make a decision on the safest lanes and the best time before crossing on ALKI when the wave and its vulnerability is likely low. Throughout the years, ALKI II is the safest lanes among others since it has been identified of having lower vulnerability than others. The knowledge of the wave characteristics for a specific location is very important to design, plan and vessels operability including types of ships and shipping lanes before their activities in the sea. -
5. ARTISANAL FISHERIES There Is No Universal Definition of “Artisanal Fisheries” but Common Criteria (SEAFDEC 1999) Include 1
ACIAR Project FIS/2001/079 5. ARTISANAL FISHERIES There is no universal definition of “artisanal fisheries” but common criteria (SEAFDEC 1999) include 1. Small scale and often decentralized operations, 2. A predominance of small vessels (often <10 GT), 3. A predominance of traditional fishing gears (but may include trawl, seine, gill-net, and longline vessels), 4. Fishing trips are generally short and inshore, and 5. The fisheries are often largely subsistence fisheries, but there may be some commercial component. The ports surveyed for the artisanal component of this report only meet these criteria to varying degrees, with some being home to many vessels >10 GT, and with centralized commercial operations. However, for the purposes of this study, “artisanal ports” includes not only the smallest scale of landing place at the fishing village level (i.e. what most readers would consider truly artisanal), but also these larger landing places where fishing vessels are primarily owned by fishing households, but not by fishing companies, and where the majority of vessels are smaller than 25 GT. A summary of key features of the artisanal landing places surveyed are shown in Table 5.0.1. More detailed descriptions are provided in the sections that follow. 5.1 Bungus – Padang, Pariaman, and Painan (West Sumatra) There are 5 provinces on the west coast of Sumatra – from north to south, the provinces of Nanggroe Aceh Darussalam (formerly Daerah Istimewa Aceh), North Sumatra (Sumatra Utara), West Sumatra (Sumatra Barat), Bengkulu, and Lampung. Numerous islands are located off this coast - Banyak Archipelago islands in the north, Nias Island, Tanahmasa and Tanahbala Islands, the Mentawai Islands (that include Siberut, Sipura and Pagai Islands), and Enggano Island in the south. -

Kemanan Dalam Wisata Bahari (Penyelaman dan Surfng) : Tinjauan Permen Pariwisata R.I. No. 3 Tahun 2018 KEAMANAN DALAM WISATA BAHARI (PENYELAMAN DAN SURFING): TINJAUAN PERMEN PARIWISATA R.I. NO.3 TAHUN 2018 Muhamad Ali Muchlis Staf Pengajar Akademi Pariwisata Jakarta [email protected] Abstract Indonesia has many places for diving and surfing. Indonesia is a paradise for tourists to do diving and surfing. The problem then is legal protection for these activities. In 2018 the Minister of Tourism Decree No.3 has accommodated tourism activities for diving and surfing, this will increase protection for tourists. With maximum tourism equipment and management in the field of diving tourism and surfing tourism, it is expected that an increase in the area of tourist visits or tourist destinations and can benefit the community and the country and ensure the preservation of nature. Keywords: marine tourism, diving, surfing, accommodation, legal protection. I. Pendahuluan Indonesia adalah nusa-antara wilayah dengan pulau-pulau besar dan kecil di antara Samudera Hindia dan Samudera Pasifik dengan wilayah darat sebagai rangkaian pegunungan api yang memiliki keragaman geografis dan kaya akan sumber daya alam. Keindahan alam Indonesia memang tiada tara. Sebagai bangsa bahari Indonesia mewarisi taman laut yang menakjubkan, antara lain: Bunaken, Wakatobi, dan Raja Ampat yang menyimpan kekayaan terumbu karang dunia. Di Kawasan Raja Ampat terdapat lebih dari 1.070 jenis spesies ikan, 600 jenis spesies terumbu karang, dan 66 jenis molusca. Selain Kawasan Raja Ampat, Indonesia juga memiliki Laut Sulawesi yang masih penuh misteri, karena ditemukannya ikan Coelacanth yang diduga sudah punah 65 juta tahun yang lalu. Indonesia mewarisi kekayaan pantai yang beragam, pantai dengan pasir putih, pasir coklat, pasir hitam, pantai berpasir pink seperti di Pink Beach Pulau Komodo. -

Inversion is performed with 99,741 Brst-arrival p waves from 16,196 local and regional earthquakes occurred around the Sumatra Subduction Zone (SSZ) between 1964 and 2018. Tomographic results show low-velocity (low-V) anomalies that reCect both accretion and possibly, asthenospheric upwelling associated with subduction of the Australian Plate beneath Eurasia around the SSZ. The prominent low-V anomaly is thickest around the Conrad, extending beneath Straits of Malacca and parts of peninsular Malaysia, but disap- pears around the Moho in the region. Below the Moho, the subducting slab, represented by a high-velocity (high-V) anomaly, trends in the orientation of Sumatra. At these depths, the eastern shorelines of Sumatra, most parts of Malacca Strait and the west coast of peninsular Malaysia show varying degrees of positive velocity anomalies. We consider that asthenospheric upwelling around the SSZ may provide heat source for the 40 or more hot springs distributed north–south in peninsular Malaysia. -

Located between the Pacific and Indian Oceans, Indonesia provides a central conduit for global shipping via the Strait of Malacca – a major shipping channel through which 30 per cent of global maritime trade passes. It is also home to several other key maritime transit points, such as the Makassar, Sunda and Lombok Straits. -
