Abstract

Beach is an area that is physically subject to change. This change is caused by natural processes and human activities. Physical changes that generally occur on the beach are erosion and sedimentation. The dynamic processes that occur atthe beach are the result of a combination of various forces at work on the beach, which include the force of waves,currents, sedimentary movements, wind and so on. To analyze sediment transport in coastal areas, one of the main thingsthat need to be known is the characteristics of coastal sediments. The study was carried out on beaches prone to erosion and sedimentation, the location of sample data research at several points taken in the area around the Aeng TakalarVillage Beach and Padongko Barru Beach. The analysis carried out is the analysis of the distribution of sediment grainsto determine the characteristics of existing sediments on the beach. The results showed that the sizes of the sediment samples on the beach in Aeng Village, Takalar District were a mixture of fine sand and medium sand which had a diameterof 0.125 mm - 0.5 mm and the size of the sediment grains on the Padongko beach. Kabru was a mixture of fine sand and medium sand which has a diameter of 0.125 - 0.5 mm.

Abstract

PT. Sinergi Perkebunan Nusantara plans to use the Lampia port for shipping of Crude Palm Oil (CPO). Lampia Jetty has more than ten years old so that its carrying capacity against external loads may have decreased. Therefore for the operational safety of the ship, it is necessary to study the engineering capacity of the pier. By knowing the engineeringcapacity of the existing pier, the maximum ship dimensions that can be served by pier can be determined. This study began with the collection of supporting data consisting of ship data, hydro-oceanographic data, bathymetry data, pier structure data and earthquake data. Furthermore, the load calculation that works on the pier consists of dead and live loads, earthquake loads, ship impact loads, current loads, wave loads, ship tensile loads and wind loads. After the load calculation is completed, then the pier modeling is done using SAP2000 software followed by inputting the load using aspecific combination of loading and running model. In this study the dimensions of the ship were varied namely 500 ton, 700 ton, 1000 ton, 2000 ton and 3000 ton. The indicator used in assessing the technical capacity of the pier is the safety factor (SF) as a function of the ship DWT. Based on the results of the strength analysis of the pier structure, it wasfound that the existing pier is capable and safe serving ships with a size of 27 1027 DWT if it uses a safety factor (SF) 1.5. Whereas if use the safety factor (SF) 2.0, the existing pier structure is capable and safe to service ships with a size of ≤ 510 DWT.

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
