Abstract

The objective of this study is to provide an alternative design of sediment problems in Kuala Raja Port that causes disadvantages for the local fishermen due to ineffective port utilization. The primary surveys conducted in this study are topographic survey, bathymetry survey, current survey and geological survey. The wind data is obtained from the Malikul Saleh Meteorological Station. Based on the tidal survey, the water surface during the tide water is 1,56 m above  0.00 m LWS. The current data shows that the flow rate is low, which is less than 1.5 m/sec whereas not interfere ships’ movement, because the standard size of ships allowed crossing the shipping lanes is planned less than 50 GT. Based on the correction using SPM nomogram acquired high waves 3.50 m with wind speed > 20 knots and the North largest fetch  490.04 miles. Sediment transport on shore of Kuala Raja beach is  46,934.59 m3/year moves from West to East. The hand bore data on the location of the planned jetty obtained SG = 2,648, Wc = 25.66, gd = 1,549, f = 31.00, c = 0.03. Therefore, the determination of the layout of jetty at Kuala Raja Port is considering the direction of sediment transport, the wave height that occurs, the field data attained and the economic feasibility. Sediment management at the Kuala Raja Port can be done within 2 (two) ways: firstly by increasing the length of the jetty on the left and the right side and, secondly by dredging the navigation channel. The length of the jetty that is needed to expand on the left side is 284 meters long and 127.65 meters long on the right side, in order to avoid the addition of sedimentation volume. The jetty’s slope is planned 1: 2 outside the channel and 1: 1 inside the navigation channel. The dredging volume at the port entrance is approximately 39,811.60 m3.

Abstract

Tanah ekspansif adalah tanah yang kandungan lempungnya memiliki potensi kembang susut akibat perubahan kadar air. Kondisi jalan pada ruas jalan Ie Mirah-Lama Muda (Kabupaten Aceh Barat Daya) mengalami hal yang sama, yaitu cepat mengalami kerusakan meskipun sering dilakukan perbaikan pada lapisan permukaan (surfase). Tujuan dari penelitian ini adalah untuk mengetahui apakah fly ash yang berasal dari PLTU Nagan Raya layak dijadikan bahan stabilisasi untuk proyek-proyek jalan pada tanah ekspansif khususnya ruas jalan lintas barat Aceh. Metode yang dilakukan adalah dengan melakukan stabilisasi tanah dengan menambah Fly Ash dan melakukan pengujian di Laboratorium Pengujian yang dilakukan adalah analisis kadar air, analisis saringan, analisis berat jenis, pengujian batas attenberg, analisis CBR dan pemadatan standar proctor. Hasil dari uji laboratorium menunjukkan adanya penurunan berat jenis sampel tanah disebabkan karena tanah distabilisasi dengan fly ash yang memiliki berat jenis yang lebih kecil. Hasil dari penambahan Fly Ash menurunkan kadar air dalam campuran tanah. Hal ini sangat menguntungkan dalam proses stabilisasi karena potensi pengembangan tanah semakin berkurang. Hasil test Attenberg menunjukkan penambahan Fly Ash 20% mampu menurunkan nilai indeks plastisitas dari 28,61% menjadi 2,88%. Hal ini terjadi karena penambahan Fly Ash menyebabkan terjadinya ikatan antar partikel dan tertutupnya sebagian pori-pori tanah sehingga tanah menjadi kurang sensitif terhadap perubahan kadar air. Penambahan Fly Ash meningkatkan berat isi kering karena terjadi perubahan distribusi butiran halus menjadi tanah berbutir kasar sesuai banyaknya penambahan Fly Ash. Penambahan fly Ash 20% memberikan peningkatan yang cukup signifikan dengan nilai CBR sebesar 15,7% dibandingkan daya dukung tanah asli yang hanya memiliki nilai CBR 3.4% dan tergolong tanah yang jelek. Fly Ash yang berasal dari PLTU Nagan Raya layak untuk dijadikan bahan stabilisasi tanah dalam pelaksanaan konstruksi khususnya jalan raya yaitu sebagai subbase course
