PUSAT KULINER SEAFOOD DI MUARA LAUT SUNGAI KAKAP, KABUPATEN KUBU RAYA

Indonesia is a maritime country because it has an area of water reaching 3.25 million km2 or about 63%. The sea mouth of the Sungai Kakap, Kubu Raya regency, is part of the Indonesian maritime region that has fisheries management or WPP711 Natuna Sea, making it the second largest fish producing region in West Kalimantan. Sungai Kakap is part of a strategic tourism area that can be further developed. UnfortuUnfortunately, it wasn’t felt the benefits by the surrounding community. Based on these, the architectural response must offer a place containing the results of the marine resources of culinary-tourism based on Sungai Kakap and connected to the existing restaurant as the Seafood Culinary Center of Sungai Kakap Estuary. By realizing a cooperative system with the Sungai Kakap community, it is hoped that the design will improve the quality of life of the residents of Sungai Kakap. Applying the glass box method, planning becomes more objective, using the information obtained during data collection, which is supported by a clear conceptual analysis and synthesis. With a land area of 1.39 hectares, Sungai Kakap Estuary Seafood Culinary Center consists of a new mass area, an existing masses area and a space connecting the masses. The new area masses will consist of a restaurant function with different services than the current restaurant/market place, and a workshop/community-kitchen with movable internal walls. A connecting space used as a plaza and for culinary events.

DEVELOPMENT OF OCEAN RENEWABLE ENERGY MODEL IN INDONESIA TO SUPPORT ECO-FRIENDLY ENERGY

Abstract. Renewable energy is a solution for reducing environmental damage caused by greenhouse gas emissions from fossil fuels. Energy consumption in Indonesia involves sectors such as industry, households, transportation, and agriculture, which still heavily rely on non-renewable energy sources. Indonesia possesses significant maritime potential, boasting the second longest coastline in the world, a water area covering 71%, and abundant marine biological resources that can contribute to maritime economic growth. This research aims to leverage remote sensing technology and geographic information science to harness Indonesia's maritime potential. In the realm of renewable energy, this study emphasizes the potential of wave energy and current energy in Indonesia, with the objective of establishing an Ocean Renewable Energy (ORE) model. Additionally, the research will consider marine habitat suitability to mitigate any negative impact on biodiversity from power generation activities. Based on the research findings, the ocean current energy in Lombok Strait has a high energy potential reaching 1,035 Watts and Maluku Sea has 1,536 Watts, while the southwest region exhibits wave energy potential of Panaitan Island has a wave energy potential of 23,051 kW/m, while Sangiang Island has a potential of 12,842 kW/m. Furthermore, potential energy locations will be identified through the overlaying of potential fish zones. The ultimate goal of this research is to fulfill sustainable energy needs, decrease dependence on fossil fuels, and promote sustainable economic growth in Indonesia.

Development of Indonesian Maritime Sovereignty Culture Through Indonesian Maritime Policy with Indonesian Maritime Defense Strategy

In the past, Indonesia wielded a significant influence over the Southeast Asia region and beyond, particularly through the Srivijaya Kingdom and later Majapahit's maritime prowess. Indonesia's natural affinity for maritime culture predates its very conception and is evident in the vast territorial waters surrounding almost all of its provinces. This unique geographical aspect makes Indonesia an archipelagic state with a maritime tradition. To support Indonesia's maritime defense, it is crucial to promote the prosperity of its maritime affairs. The country's national defense strategy takes into account its archipelagic nature. Maritime culture is a key aspect of the five pillars that drive Indonesia towards becoming a World Maritime Fulcrum. This policy point recognizes that a robust maritime culture is fundamental to the formation of Indonesia's maritime defense. Strong maritime culture begets a robust maritime defense, highlighting the interdependence of these two critical components. Keywords: maritime culture, maritime defense, maritime power, world maritime fulcrum

Long-term trend and variability of ocean heat content in the Indonesian Maritime Continent

The evolution of 64 years of the ocean heat content for the upper 300 meters (OHC300) in the Indonesian Maritime Continent, viz the Banda Sea, the Sulu Sea, the Java Sea, and the Karimata Strait, was investigated using the combination of ocean and atmosphere reanalysis data. The study aims to understand its long-term trend variability and association with El Niño-Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD). The result showed a positive trend in all basins except the Banda Sea. The most significant rise was the Sulu Sea. The IOD fluctuation was more pronounced in the Western part of Indonesia. In contrast, the ENSO variation was more apparent in the Eastern part of Indonesia. The coincided La Nina events and the negative IOD significantly increased OHC—conversely, the coinciding of the El Niño events and the positive IOD caused a decrease in OHC magnitude. The significant factor increasing OHC in the maritime continent is the ENSO fluctuation, followed by the IOD fluctuation.

Propagation of tropical squall line-induced storm coastal inundation episodes in Java-Bali, Indonesia

The short-lived tropical squall lines could trigger weather-related hazards to the northern part of the Indonesia Maritime Continent (IMC), such as Sumatra and Kalimantan. Herein, we investigated the rare propagation event of the long-lived Sumatra squall line associated with a severe storm surge that induced coastal inundation in Java-Bali with devastating impacts from 22 May–2 June 2020. With a comprehensive approach combining observational, numerical, and analytical studies, for the first time, we proposed the possible mechanism related to the long-lived squall line over the IMC, which represents the largest equatorial tropical region with the most complicated air-sea interaction area in the world. Our findings suggest that the long-lived squall line related to the supercell-like thunderstorm initiated from multicell over central Sumatra on May 20, 2020, continuously propagated southeastward until several days later reached Bali. The near-quasi steady convective line has 6 hours of time travel from central Sumatra to west Java. The supercell-like rapidly develops from multicell with a deep convective updraft under the strong and fast cold pool (∼13.8 m s−1). The further southeastward propagation of squall line with broken line type seems reinforced by low-level moist transport from the Java Sea. This study also suggested that this unusual event of a long-lived squall line might occur more frequently in the warming upper ocean in the IMC.

Prediction of the Sea Level from the PUMMA System Using SARIMA

The rising sea levels can threaten millions of people residing along the coast or lowlands. The risk can be mitigated by the sea-level prediction done by collecting information on the likelihood of rising sea levels. The Ministry of Marine Affairs and Fisheries of Indonesia has developed Perangkat Ukur Murah untuk Muka Air Laut (Inexpensive Device for Sea Level Measurement, PUMMA) to measure sea levels. PUMMA is located in remote monitoring stations based on Indonesian maritime area. The PUMMA system currently lacks a prediction feature. This objective of this study is to model the sea-level prediction using the dataset for one year, from July 2021 until July 2022. The seasonal autoregressive integrated moving average (SARIMA) method was used because SARIMA proved to be a flexible and versatile method for a dataset having noncomplex nature and seasonal patterns. This study has developed several models of the SARIMA. The model performance was evaluated using the mean absolute percentage error (MAPE), R-squared, mean square error (MSE), and root mean square error (RMSE) metrics. The SARIMA(1, 1, 0)(1, 1, 1)12 model achieved the lowest prediction error with an R-squared of 0.508, MSE of 0.0479, and RMSE of 0.069. Based on the performance, SARIMA(1, 1, 0)(1, 1, 1)12 model is feasible for predicting sea levels using the PUMMA dataset.

Unlocking Opportunities: Tourism Ship Financing Through Leasing Agreements for Micro, Small, and Medium Businesses in Indonesia

Objective: This research explores the prospects of leasing agreements as a financing solution for tourist boats for MSMEs, considering the vast potential of marine tourism in Indonesia. Despite the potential benefits of leasing agreements, no specific regulations govern them, resulting in deviations from leasing principles and limited understanding among stakeholders. Methods: The study adopts the triangle legal pluralism approach and focuses on the Special Capital District of Jakarta and Labuan Bajo as significant marine and tourism industry hubs. Primary data collection includes interviews, observations, and secondary data from legal documents and literature. The analysis employs deductive and inductive logic and triangulation for validation. Result: According to this study, leasing agreements can help Indonesian tourism MSMEs finance tourist boats. Indonesia's maritime tourist business has great potential due to its archipelago and natural resources. However, MSMEs need help to acquire capital to ensure tourist boat growth, impacting tourism services and experiences. The following suggestions aim to unlock potential and promote sustainable tourism growth: Include Rental Contract Laws: Due to the industry's lack of rules, leasing agreements vary and cause disputes. Implementing lease agreement guidelines will provide legal certainty, protect lessors and lessees, and ensure fair and transparent business practices; Because many need help understanding, outreach, and education must increase. Leasing Agreements must broaden and organize outreach to educate MSMEs, business actors, and the public about leasing's benefits and processes. Suggestions: Ultimately, this research aims to provide valuable insights for policymakers, businesses, and academics to promote tourism ship financing through leasing agreements to grow the Indonesian tourism industry.

Community Empowerment in Outermost Small Islands in Maintaining Territorial Integrity and Realizing Indonesian Maritime Defense

Negara Kesatuan Republik Indonesia (NKRI) is an archipelagic country. Indonesia's struggle to gain world recognition as an archipelagic country was first obtained through the Archipelagic State Concept in the Djuanda Declaration on December 13, 1957. Indonesia's maritime territory is an area rich in resources that are beneficial for the welfare of society. So far the development of the outer islands has not shown good results. This is caused by many factors, among others, geographically the location of the outermost islands is difficult to reach, there are limited business scales, methods of exploiting marine resources that are not yet effective, limited facilities and infrastructure, limited ability to manage available natural wealth. This research aims toanalyze community empowerment activities living on these islands as one of the efforts to maintain territorial integrity and realize Indonesia's maritime defense. This research is a qualitative research. The research design is descriptive analysis. The results of this study arecommunity empowerment in the outermost small islands in maintaining territorial integrity and realizing Indonesia's maritime defense through the Service of the Indonesian Navy, Development of Regional Resilience and Social Communication and the Government of Natuna Regency providing various types of assistance, such as socialization of fish farming and fishing gear.The empowerment cooperation carried out by Lantamal IV Batam with the Regional Government of Natuna Regency has not gone well, the actors involved in implementing the empowerment cooperation have not worked together optimally and there are still obstacles faced, namely uniting community empowerment activity programs between Lantamal IV Batam and Natuna Regency.

Indonesian Maritime Diplomacy

This article discusses why the Indian Ocean Rim Association (IORA) is significant for Indonesia and how Indonesia plays a strategic role in IORA to realize national interests and advance its vision as the World Maritime Axis? In answering these questions, we build arguments based on Christian Le Miere's theory of maritime diplomacy and Helen Milner's theory of international cooperation. The argument in this article consists of two things. First, IORA is very significant for Indonesia because the organization has a common vision with Indonesia's national interest. Second, in order to achieve this goal, the Indonesian government utilizes cooperative and persuasive maritime diplomacy as a means of enhancing international cooperation. This is demonstrated by Indonesia's involvement in encouraging negotiations and facilitating cooperation in the IORA forum. This is also reinforced by Indonesia's election as chair of IORA for the period 2015 to 2017 as a manifestation of Indonesia's existence as a maritime country in the international arena.

Cold Surge Effect on Vertical Profile Atmosphere over Meteorological Station of Ranai Natuna: Case Study Asian Winter Monsoon 2019/2020

During the Asian Winter season, which spans from November to February, the phenomenon of cold surge often occurs, leading to increased convective activity over the western Indonesian Maritime Continent. The location of Natuna Island, situated in the southern part of the South China Sea, is of particular importance for studying cold surges due to their propagation over this area. In this study, the vertical structure of the atmosphere was analyzed using radiosonde observation data collected at the Meteorological Station of Ranai Natuna. The analysis focused on physical parameters such as air temperature and relative humidity, atmospheric kinematics including wind direction and speed, as well as atmospheric thermodynamic parameters such as Lifting Condensation Level (LCL), Level of Free Convection (LFC), Equilibrium Level (EL), Convective Available Potential Energy (CAPE), and Convective Inhibition (CIN). The results indicate that during the passage of a cold surge, air temperature (T) tends to be higher in the lower troposphere, including at the surface, but lower in the middle and upper troposphere. Relative humidity (RH) also tends to be higher during cold surges, with a significant increase in the middle and upper troposphere. In the lower troposphere, the wind direction shifts from east to northeast at a higher speed compared to when a cold surge is absent. Furthermore, the LCL and LFC heights are elevated during the presence of a cold surge, while the EL height shows an insignificant decrease. It is worth noting that intense rainfall occurs, particularly when the cold surge is more pronounced, even though the values of CAPE and CIN do not change significantly.

Reformulation of Regulations in the Context of Structuring the Indonesian Maritime Security Regime

This article discusses the reformulation of regulations in the context of structuring the Indonesian maritime security regime. The research employs a qualitative method using secondary data sources obtained through a literature review. The specific background of problems addressed in this research includes issues related to IUU fishing and other maritime security threats faced by Indonesia. The main problem addressed is the lack of cross-sectoral coordination and frequent differences in perception of authority among law enforcement agencies at sea. The research objective is to examine how restructuring Indonesia's maritime security regime can be achieved through reformulation of overlapping regulations and harmonization of authority among maritime security agencies. The article concludes that the restructuring of Indonesia's maritime security regime can be achieved through these measures.

Realizing Indonesia as a Global Maritime Fulcrum

The idea of the Global Maritime Fulcrum (GMF) becomes a maritime strategic approach. The government of President Jokowi with the vision of the GMF is determined to rebuild Indonesia's maritime glory. Maritime security is one of the key factors to guarantee the pillars of sovereignty and prosperity. A strong foundation for building Indonesia's vision as the GMF is the nation's geostrategic location and historical overview. The realization of Indonesia as the GMF has a strong foundation, both legal basis, historical review, and socio-economic strength. An important aspect to be developed in order to realize the GMF is the maritime and maritime economic aspects, as well as aspects that are components of governance. The transformation of the defense system, namely land, sea and air can support realizing Indonesia as a Maritime Fulcrum. The idea of realizing Indonesia as a GMF must have relevance between foreign policy and the geographical character of a country and assumptions about establishing the concept of making Indonesia a GMF.
