Cahyaningtyas, Elok Tiara (2019) Studi Perencanaan Pemecah Gelombang (Breakwater) di Pantai Sanur Kota Denpasar Provinsi Bali. Sarjana thesis, Universitas Brawijaya.
Abstract
Perencanaan pemecah gelombang mula-mula dilakukan dengan menganalisis gelombang datang dengan kala ulang 25 tahun yang bertujuan untuk memperoleh dimensi pemecah gelombang. Pemecah gelombang ini menggunakan tipe pemecah gelombang Roublemound (tumpukan batu). Setelah didapatkan dimensi, akan dihitung stabilitas bangunan terhadap kelongsoran rotasi dan daya dukung tanah. Pondasi tiang pancang yang direncanakan mengunakan kayu gelam. Hasil perencanaan ini diperoleh gelombang dominan dari arah Tenggara dengan tinggi gelombang signifikan sebesar 1,50 m untuk kala ulang 25 tahun. Pemecah gelombang terletak pada elevasi 0,0 m dengan tinggi puncak pada elevasi + 5,10 m, panjang 1315 m sepanjang garis pantai, berat batu pelindung terluar sebesar 2,11 ton dengan diameter 1,16 m. Analisis stabilitas lereng terhadap kelongsoran rotasi mengunakan bantuan software Geostudio Geoslope dengan metode Fellenius, Bishop dan Janbu dapat dikatakan aman. Pondasi tiang pancang direncanakan sedalam 7m dengan diameter tiang pancang sebesar 0.2 m. Total rencana angaran biaya (RAB) dengan material pondasi tiang pancang mengunakan dolken kayu gelam sebesar Rp 60.381.849.000,00
English Abstract
The coastal morphology of Sanur Beach has changed due to erosion from wave motion.The damages of the settlements, public facilities and other buildings were caused by the changes of coastline can be minimized by a breakwater construction. The initial stage to design the breakwater was analyzing the design wave witha 25 year of return period. After the dimension is obtained, the stability of breakwater structure against the rotational slide and the bearing capacity of the soil can be evaluated. The utilized alternative pile foundation was made of gelam wood. From this study, it was observed that the dominant waves came from southeast with a significant wave height of 1.50 m for a 25-year of return period. As a final design, the height of breakwater is 5.10 m with a length of 24 m and 17,9 m along the coastal line. The weight of the outer protective rock is 2.11 tonnes with a diameter of 1.16 m. From the analysis of slope stability using Geostudio Geoslope software with Fellenius, Bishop and Janbu method indicates that this structure was stable against rotational slide. The depth of pile foundation is 7 m with a diameter of 0.5 m. The estimation of total cost with pile foundation using gelam wood is Rp 63,381,400,000.
