Abstract

North Galesong District, an area located in Takalar Regency, is a coastal area with abundant natural resources and significant economic potential. Coastal areas are areas where sea and land meet. Despite this, people living in the coastal areas of North Galesong sub-district still face economic challenges that need to be addressed. Therefore, it is important to empower coastal communities in North Galesong Sub-district so that they can improve their economy and achieve sustainable development. Empowerment is an effort to increase the capacity and independence of individuals or communities in meeting their own needs. The goal of this paper is to propose a coastal community empowerment model that can be implemented in North Galesong District. The research was conducted by combining a literature review of empowerment models that have been successfully implemented in other coastal areas and analyzing the local situation in North Galesong District. The results show that an empowerment model suitable for North Galesong Sub-district should consider local characteristics and existing economic potential.

Abstract

The ocean possesses advantages as a sustainable and predictable source of energy, with tidal energy being one such marine-derived energy source. This study examines the analysis of ocean energy potential in the study location of the Bali Strait. The analysis of tidal energy potential follows the guidelines of the European Marine Energy Center (EMEC) and employs numerical modeling to identify current velocities using Delft3D. This study investigates the influence of water depth columns to determine the optimal depth for the placement of energy conversion technologies. It is found that the highest current velocities occur in the strait's narrowed section. Furthermore, from the analysis of tidal energy potential, it is determined that upper water depth columns (9 m, 19 m, and 26 m) can generate twice as much energy as the lower water depth columns (40 m and 45 m).

Abstract

With the rule of Indonesian Law No. 3 of 2023 concerning the Stipulation of Perpu 2 of 2022 concerning Job Creation and its derivatives/OMNIBUSLAW which have an impact on the management of licensing for the utilization of marine space, wave height datasets which are data that must be attached to the proposal for submission of a Marine Space Utilization Conformity Confirmation Approval (PKKPRL) are very important. However, most of the existing data requires further analysis and will make it difficult for small-scale marine space utilization businesses with activities that have a relatively low level of risk to the marine and coastal environment. Therefore, a dataset of wave height data that has been analyzed from the available data is needed so that it will be easily used by small-scale marine space utilization businesses in submitting PKKPRL proposals. This study presents an analysis of maximum wave height in the period 1999-2023 in Sulawesi seas obtained from monthly significant wave height data from altimetry satellites that have been reanalyzed by ECMWF (European Centre for Medium-Range Weather Forecasts) and presented in the form of digital maps. This dataset is expected to make it easier for small businesses to utilize it in the process of applying for marine space utilization permits.

Abstract

Kesesuaian kegiatan pemanfaatan ruang laut (KKPRL) adalah kesesuaian antara rencana kegiatan pemanfaatan ruang laut dengan rencana tata ruang dan/atau rencana zonasi. KKPRL diwajibkan bagi setiap orang atau badan usaha yang melakukan kegiatan pemanfaatan ruang laut di perairan pesisir, wilayah perairan, dan/atau wilayah yurisdiksi secara menetap di sebagian ruang laut. Semua bentuk pemanfaatan ruang laut memerlukan izin dari Ditjen Pengelolaan Ruang Laut. Dalam pelaksanan pengajuan PKKPRL, dokumen yang diajukan oleh pihak pelaku usaha tidak sesuai dengan harapan tim penilai dokumen sehingga siklus persetujuan dokumen membutuhkan waktu lama akibat adanya koreksi yang berulang. Makalah ini bertujuan untuk mensosialisasikan penyusunan dokumen pengajuan PKKPRL sesuai aspek teknis ketentuan UU No. 6 tahun 2023, sehingga akan mereduksi waktu pengajuan dokumen PKKPRL. Dalam pertimbangan kelayakan aspek teknis dokumen yang diajukan, tim penilai membuat data pembanding sebagai parameter penilaian dokumen pemanfaatan ruang laut dengan memberikan masukan/saran terkait peninjauan aspek teknis, sehingga dibutuhkan perbaikan dokumen sesuai persayaratan KKPRL. Hasil akhir pemeriksaan dokumen pengajuan, tim penilai memberikan rekomendasi surat penolakan ataupun penerbitan persetujuan KKPRL.

Abstract

Ocean currents are the flow of water in the ocean, influenced by factors such as temperature and salinity gradients, wind stress, gravitational forces from the moon, and bathimetry of ocean. These currents follow specific patterns and significantly impact climate, weather, and marine ecosystems. This study focuses on validating field measurements of current speed against simulated speed generated by the MIKE 21 software, a widely used tool for hydrodynamic modeling in coastal engineering. The validation process involved comparing in-situ measurements of current speed, obtained using an acoustic Doppler current profiler, with the simulated currents from MIKE 21. The simulation parameters were calibrated to reflect the field conditions accurately. The results indicated that the maximum discrepancy between field measurements and the model's simulated currents was approximately 6.3%. This level of agreement confirms that the MIKE 21 model accurately represents the field conditions. Therefore, the model's predictions can be reliably used for other hydrodynamic simulations and coastal management applications.

Abstract

One of the rivers with potential for development into a river transportation system in the city of Makassar is the Tallo River, which is approximately 22.2 km long. This river can connect the Tamalanrea sub-district with the coastal area of Makassar. Currently, the Tallo River is utilized as a transportation route to Lakkang Island, which is one of the tourist destinations. Based on the relatively wide characteristics of the river, the Tallo River can accommodate vessels with a relatively large draft. However, a study is needed to determine the maximum draft of vessels that can operate in the river based on water depth and air clearance at the Reformasi Toll Bridge. The objective of this research is to determine the maximum draft and freeboard of vessels that can operate in the Tallo River, identify areas of shoaling, and calculate the volume of dredging required. The research begins with literature review, collection of secondary and primary data, data analysis, and identification of shoaling points for calculating dredging volume. The data collected includes bathymetric data, tidal data, current data, bottom sediment data, and river discharge data. Based on the data analysis results, the maximum vessel draft before dredging is 1.0 m LWL with an air clearance of 1.9 m from the high tide water level. After dredging, the draft of vessels that can use the Tallo River is 1.5 m LWL. The locations requiring dredging are 13 points, with a total dredging volume of 1283.49.

Abstract

Accurate time estimation is the key to the success of KM Wilis repair activities at PT Industri Kapal Indonesia (Persero). Delays in ship repair activities will be able to cause losses for shipowners in fulfilling shipping transport service schedules. This study aims to develop a reparation plan for KM. Wilis with critical path method in order to obtain the optimal duration of repair work. Based on the KM Wilis repair list, repair activities were identified into smaller components (work breakdown structure) to determine the relationship between preceding and preceded activities. The repair list is also used as a guideline for data analysis, which includes job descriptions, labour, duration, and work volume. Critical Path Method as a time management method is used to identify activities that are on the critical path. KM Wilis repair time estimation obtained a duration of 33 days with critical path activities including tug boat services, docking services, hull cleaning work with water jets, hull cleaning work with scrap, unloading skerm bush pintles and rudder leaf pens, dismantling of the lowered rudder leaf on the dock floor, making new left rudder leaves, reinstalling rudder leaves, undocking services, tug boat services and sea trials.

Abstract

At the Fish Landing Harbor (PPI) coastal protection buildings have been built to protect the area in an effort to obtain calm waters at the harbor. A breakwater is infrastructure built to break waves by absorbing wave energy. The types of wave breakers are sloping side breakwaters, vertical side breakwaters and mixed wave breakers. Waves are a form of energy that can shape beaches, cause currents and sediment transport in perpendicular directions and along the coast, and cause forces that act on coastal buildings. The aim of this research is to determine the characteristics of wave transmission and alternative breakwater construction in ports, simulated using a numerical hydrodynamic model to simulate waves. The input data is wave height, wave period and wave direction. The Fish Landing Harbor Breakwater (PPI) is not yet optimal because the waves entering the port area in the west season reach 1.2 meters. Based on the results of the breakwater design used to optimize its function, this can be proven by the existence of breakwater construction designed in modeling where the breakwater with a length of 150 m, the wave height entering the protected area is 0.81 m, the breakwater with a length of 300, the wave height entering the area protected by 0.2 m, and a breakwater with a length of 500, the wave height entering the protected area is 0.03 m.

Abstract

Human life cannot be separated from the use of energy. Energy is needed for many things like cooking, traveling, and working. Currently, electrical energy is the main need. To produce electrical energy, power plants that utilize renewable and non-renewable energy sources are needed. Technology in the field of renewable energy continues to experience rapid development. The use of renewable energy aims to reduce the impact of global climate change and reduce dependence on fossil fuels. A variety of natural resources are available as renewable energy alternatives, one of which is marine power technology. Marine energy technology is a technology that utilizes various properties and movements of the ocean to generate electrical energy. Energy sources from the sea can be utilized by using marine technology such as ocean current technology, ocean wave technology, and ocean thermal energy conversion. This technology makes it easy to adapt to the characteristics of the exploited sea.

Abstract

Madden-Jullian Oscillation (MJO) climate variability is global climate variability that can influence oceanographic conditions, including sea surface temperature. This research was conducted to determine the influence of the MJO phenomenon on sea surface temperature variability during the Asian Monsoon period in the Makassar Strait. The data used in this research are MJO monitoring data from BOM, sea surface temperature data from NOAA's Aqua MODIS Satellite. The method used in this research is to group active MJO events into phases 2, 3, 4 and 5 and then create a monthly average SST. Next, determine the monthly SST anomaly and then analyze it. The research results show that when the MJO is active in phases 2,3,4 and 5, there is an increase and decrease in SST
