Abstract

Ekspor dan impor batubara tidak jarang terjadi di Indonesia khususnya Gorontalo Sulawesi Utara yang selalu terlibat dalam kegiatan ekspor dan impor batubara. Batubara merupakan salah satu sumber energi penting di negara ini. Kegiatan tersebut selalu melibatkan kapal. Sebuah kapal tentunya membutuhkan stasiun seperti halnya transportasi lainnya. Ada 2 jenis dermaga di alam semesta kapal, dermaga terbuka dan dermaga tertutup. Konstruksi dermaga terbuka memiliki berbagai peraturan agar kapal dapat berlabuh dengan aman. Berbagai hal dapat mempengaruhi bentuk bahkan kekuatan struktur pelabuhan. Mulai dari arus laut, pasang surut air laut, hingga jenis kapal diperhatikan kebutuhan struktur pelabuhannya. Dermaga yang direncanakan adalah dermaga bertipe open pier. Perencanaan yang dilakukan meliputi evaluasi layout, perhitungan struktur dermaga, pengerukan, serta dinding penahan tanah. Dari perencanaan dermaga tersebut, metode pelaksanaan juga dilakukan hingga perhitungan rencana anggaran biaya. Hasil dari perencanaan jetty open pier untuk kapal tongkang 10.000 DWT meliputi, rekomendasi kedalaman minimal -6,5 mLWS. Rekomendasi dimensi jetty dengan Panjang 108 m dan lebar 20 m pada elevasi +2,5 mLWS. Dari hasil perhitungan struktur atas, di dapatkan pelat dengan tebal 35 cm. Lalu untuk kebutuhan balok pada struktur jetty (500 x 750 mm) dan balok fender (2600 x 2500 x 1200 mm). Untuk poer single dibutuhkan (2000 x 2000 x 1000 mm) dan poer ganda (3000 x 2000 x 1000 mm). Dari hasil perhitungan struktur bawah, didapatkan kebutuhan tiang pancang baja D609 mm dengan tebal 12 mm untuk struktur jetty. Kebutuhan volume keruk sebesar 20.300 m3. Dimensi breast wall (400 x 2000 mm), dimensi kantilever (150 x 250 mm), dimensi kaki (2500 x 400 mm), dan tebal pengaku sebesar 30 cm. Dari hasil perhitungan keseluruhan, dapat direncanakan metode pelaksanaan sebagai berikut. Pekerjaan persiapan, pekerjaan pengerukan, pekerjaan dinding penahan tanah, pekerjaan struktur jetty, dan pekerjaan instalasi fender dan bollard. Dari pekerjaan tersebut, total biaya yang dibutuhkan adalah Rp. 51,324,256,809

Coal exports and imports are common in Indonesia, especially Gorontalo, North Sulawesi, which is always involved in coal export and import activities. Coal is one of the important energy sources in this country. These activities always involve ships. A ship certainly needs a station like any other form of transportation. There are 2 types of docks in the ship universe, open pier and closed pier. Open pier construction has various regulations so that vessel can dock safely. Various things can affect the dimension and even the strength of the port structure. Starting from ocean currents, tides, to the type of ship, pay attention to the needs of the port structure. The planned pier is an open pier type pier. The planning carried out includes evaluating the layout, calculating the pier structure, dredging and retaining walls. From the planning of the pier, implementation methods are also carried out to calculate the planned cost budget. The results of planning an open pier jetty for a 10,000 DWT barge include a minimum depth recommendation of -6.5 mLWS. Recommended jetty dimensions are 108 m long and 20 m wide at an elevation of +2.5 mLWS. From the results of the upper structure calculations, a plate with a thickness of 35 cm was obtained. Then for the beam requirements for the jetty structure (500 x 750 mm) and fender beams (2600 x 2500 x 1200 mm). For single pile cap required (2000 x 2000 x 1000 mm) and batter pile cap (3000 x 2000 x 1000 mm). From the results of the substructure calculations, it was found that D609 mm steel piles with a thickness of 12 mm were needed for the jetty structure. Dredged volume requirement is 20,300 m3. Breast wall dimensions (400 x 2000 mm), cantilever dimensions (150 x 250 mm), foot dimensions (2500 x 400 mm), and stiffener thickness of 30 cm. From the overall calculation results, the implementation method can be planned as follows. Preparatory work, dredging work, retaining wall work, jetty structure work, and fender and bollard installation work. From this work, the total cost required is Rp. 51.324.256.809
