Abstract

Subsea pipes are a tool for flowing water, oil and gas fluids. By using this underwater pipe installation, fluids can be transferred from one place to another, from a production unit to another production unit, from a storage unit to a processing unit, and from a process transferred to a storage unit. During the production process, safety must be guaranteed to avoid fatal damage such as anchor drag, sinking ships, nets or trawls and other factors such as pipe corrosion. To prevent corrosion in pipes, we need appropriate and practical solutions. We can prevent this from happening by conducting a literature study regarding the application of optimization planning for cathodic protection in pipes. The design and analysis process discusses cathodic protection analysis, which refers to the DNV GL-RP-F103 standard criteria. Additional discussion is carried out as an optimization step, namely analyzing the type of paint used based on DNVGL-RP-B401.

Abstract

Breakwater adalah bangunan pantai yang didesain untuk melindungi daerah perairan pelabuhan dari gangguan gelombang. Pemecah gelombang yang saat ini banyak digunakan adalah tipe tumpukan batu, baik batu alam maupun buatan. Kelemahan breakwater tipe tumbukan batu adalah dimensinya yang besar sehingga harga yang dikeluarkan juga sangat mahal. Oleh sebab itu diperlukan alternatif tipe pemecah gelombang baru yang dimensinya lebih kecil dan biaya pembangunannya menjadi lebih sedikit. Salah satu solusi yang dapat diaplikasikan adalah hanging sheet pile breakwater. Penelitian ini dilakukan di Laboratorium Riset Teknologi Kelautan Universitas Hasanuddin dimana parameter penting kaitannya dengan kinerja struktur sheet pile sebagai pemecah gelombang adalah besarnya gelombang transmisi. Hal inilah yang menjadi pokok kajian dalam penelitian ini. Tujuan penelitian ini adalah mengetahui pengaruh parameter gelombang (Hi/gT2) dan struktur (b/D) terhadap gelombang transmisi yang dihasilkan oleh respon struktur dalam saluran gelombang (wave flume) yang dilengkapi dengan alat pembangkit gelombang dan alat ukur gelombang. Dalam penelitian ini dilakukan variasi tinggi gelombang (H) sebanyak 5 variasi, periode gelombang (T) sebanyak 5 variasi, dan jarak antar sheet pile (b) sebanyak 3 variasi. Hasil dari penelitian ini menunjukkan bahwa nilai Kt akan semakin menurun dengan bertambahnya nilai Hi/gT2. Sehingga semakin kecil nilai b/D maka nilai Kt akan semakin meningkat

Abstract

Salah satu tipe pemecah gelombang yang potensial dikembangkan untuk mengatasi permasalahan pantai dan pelabuhan adalah hanging breakwater. Pemecah gelombang ini relatif murah dibandingkan pemecah gelombang tumpukan batu. Dilihat dari sisi biaya, pemecah gelombang ini relatif murah. Namun perlu dilakukan kajian untuk mengetahui parameter yang berpengaruh terhadap besarnya gaya gelombang yang bekerja pada bangunan ini. Penelitian ini adalah penelusuran pustaka terkait untuk menyusun formula yang dapat digunakan untuk menghitung gaya gelombang secara analitis pada hanging breakwater. Hasil penelitian menunjukkan bahwa gaya gelombang yang bekerja pada hanging breakwater dipengaruhi oleh parameter gelombang dan parameter struktur. Semakin besar nilai Hi/D dan D/h, semakin besar nilai CG dan semakin besar nilai L/B untuk B konstan dan B/L untuk L konstan maka semakin kecil nilai CG.

Abstract

Breakwaters are highly effective breakwater constructions that can be used to protect harbor waters by interrupting wave energy coming from the deep sea. Widely used breakwaters today are of the pile type, both natural and artificial. The drawback of rock breakwaters is that they are large in size and therefore very expensive to issue. Therefore, a new type of breakwater is needed that is smaller in size and cheaper to build. One solution that can be applied is a suspended breakwater. The purpose of this study is to determine the effect of wave parameters on the coefficient of wave transmission through a suspended breakwater. The research was conducted at the Marine Technology Research Laboratory, Hasanuddin University. The parameters in this study were carried out with 5 variations of wave height, 5 variations of wave period (T), and 3 variations of model length (L). From the results of the research we have done, it can be concluded that the value of the transmission coefficient (Kt) is inversely proportional to the steepness of the wave (Hi/L). Figure 3 shows that when compared between model variations (L1 = 40 cm; L2 = 50 cm; and L3 = 60 cm) with depth conditions (d = 70 cm) and with period variations (T 1; T 1.2; T 1.5; T 1.8 and T2 s), it can be seen that the Kt value is lower in the third model variation, L3 = 60 cm with a value of 0.095 < Kt < 0.53.

Abstract

Tallo River is located in Makassar City, South Sulawesi, and has an important role in the Mamminasata region. The flow of the Tallo River that crosses the center of Makassar City has a strategic location in the urban area of Mamminasata. Ocean currents refer to the movement of water masses, both horizontally and vertically, that reach equilibrium. Factors that affect ocean currents include pressure gradients, winds, pressure or density differences, and tides. In many waters, the main factors affecting the strength of currents are wind and tides. The data used in this study included riverbank line data from Google Earth Pro, tidal data measured directly in the field from two different points, namely the Monkey pier and the Tallo pier, bathymetric data used to create an unstructured network taken directly in the field, and wind data obtained from ECMWF. The results showed that the water level in the Tallo River, Makassar, South Sulawesi was influenced by tides. At low tide, the river flow flows towards the mouth of the river, while at high tide, the direction of the river flow towards the upper reaches of the river with the current rotating in certain locations. The water level in the Tallo River ranges from 0.8 to 2.2 meters, and the current speed varies between 0.015 to 0.21 m/s.

Abstract

In 2006, the Pangandaran Regency area was hit by a tsunami caused by a tectonic earthquake measuring 7.7 SR. The slope conditions in the Pangandaran Regency area have a percentage value ranging from 0% - 4.59%, with this value the vulnerability value to the impacts of the tsunami will be greater. Looking at the slope of the area will show how the slope value is influenced. The data collection method is through previous data and secondary data. This analytical study can be a reference in considering development planning by understanding the surrounding environmental conditions and disaster history of the area, so as to minimize the impact of disasters.

Abstract

Coastal and marine geohazard threats can occur in coastal tourism areas in Makassar City. Several coastal tourism sites in Makassar City are managed by the community, namely by the Tanjung Merdeka Community Empowerment Agency (LPM) and acts as a partner for socialisation activities. Tourism managers are still ignorant of the potential for coastal and marine geohazards, such as the lack of information on geohazard signs and the potential for accidents that lead to disasters for tourism visitors. Socialisation of coastal and marine geohazards in Makassar City's coastal tourism areas has been carried out with an increase in the average knowledge of participants by 45.3%. The increase in partner knowledge includes awareness, preparedness, and disaster response attitudes about coastal and marine geohazard phenomena in coastal tourism activities, which can ultimately encourage and realise partners as community-based tourism managers who implement early warning of disaster risk and occupational safety. Strengthening partners is realised by handing over coastal and ocean geohazard signs as an early warning of disasters that can occur at tourist sites.

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

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.
