The rapid development of infrastructure in Riau Province has an impact on increasing land needs, especially in coastal areas which are dominated by soft soils. Soft soil will experience a large settlement if it is given a construction load for a long time. This is caused by the discharge of pore water in the soil causing damage to the construction structure. The preloading method on soft soil with vertical drain system is one of the most popular methods used to increase the shear strength of soft soil and control the settlement that occurs after construction. The permeability rate of soft soil is very low so that the time for consolidation to achieve the optimum shear strength will take more time. Generally, consolidation occurs only in the vertical direction, whereas in this study horizontal consolidation is obtained by modifying the consolidation test, namely by using a membrane to limit the movement of pore water when compressed by loading so that the water moves radially towards the vertical hole that filled with sand. This study aims to analyze the relationship between the vertical consolidation coefficient and the horizontal consolidation coefficient on the physical properties of the soil through laboratory tests. Soil samples used in this study were taken in undisturbed conditions. The results of this study obtained differences in the decline that occurred in various types of soil from the coastal areas of Riau Province. The largest land subsidence for vertical consolidation and horizontal consolidation is on the Pakning River. Based on the results of testing that has been done, the correlation coefficient cv and coefficient ch, is obtained by means of linear regression. Correlation of coefficient cv and coefficient ch obtained empirical correlation value in an equation ch = 11.088cv + 0.0005. Keywords : Soft Soil, Vertical Drain, Vertical Consolidation, Horizontal Consolidation, Square Root of Time Method.

Gradation and grain shape of sand are some of the factors that influence the shear strength of sand. This needs to be considered, so that the effect can be maximized for construction related to sand. The purpose of this research is to find out how to analyzethe shape of the sand grains and analyze the behavior of the angle of friction (ϕ) due to the influence of the grading and shape of the grains. The test is carried out by dividingthe gradation, which consists of three variations with a relative density of 70%. Gradation 1 is dominated by medium granules as much a 100%, gradation 2 is dominated by coarse granules as much a 60%, and gradation 3 is dominated by finegranules as much a 60%. The shape of the sand grains is divided into two forms, namely the group of angular and rounded grains, which are distinguished based on themorphological parameters of the granules namely roundness (R), sphericity (S) and regularity (ρ). The morphological parameters of the granules are analyzed usingimageJ. The results showed that the analysis of grains shape of sand using imageJ, obtained levels of grain shape from the two sands, namely sub-angular and subrounded.The effect of gradation on angle of friction (ϕ) is gradation dominated bycoarse grains of 60%, namely gradation variation 2, and which has a long grain distribution, namely gradation variation 3 has a higher angle of friction (ϕ) compared to gradation variation 1. Comparison of the angle of friction (ϕ) between the grainshape of sand, that is sand with a sub-angular shape has a higher the angle of friction (ϕ) compared to sand with a sub-rounded shape.Keywords: Sand, gradation, particle shape, imageJ, roundness (R), sphericity (S), regularity (ρ), angle of friction (ϕ).

Abstract. Breakwater is one of coastal structures to overcome problems of abrasion. Due to difficulties in obtaining rock material at the coast area, so the using of sandbags as a breakwater providing advantages in utilizing local materials. Therefore, the problem of the rock material supply can be overcome. The environmentally oriented conservation of the coastal protection is necessarily built without damaging the beauty of the coast itself. That is why this research on behavior of the stability of submerged sandbag breakwater is carried out this experimental research conducted in 2-D physical model and take place on the flume tank of Laboratory Ocean Engineering Department, ITS Surabaya for stability test, it shows that the deformation of the sandbags is influenced by the elasticity of sandbags which depends on its dimension and density. The sandbags size influences the grip zone. As a result, the deformation of sandbag depends on the wave forces, as a consequence of the change of slope and cross areas due to sandbags shape and formation type. The formation of SK1 has relatively high stability; the structure with mild slope is more stable, and the sandbag shapes B1 more stable than B2 Abstrak. Pemecah gelombang merupakan salah satu struktur pantai yang digunakan untuk mengatasi permasalahan abrasi. Namun sering sulit ditemukan material batuan di lokasi tersebut, maka penggunaan kantong pasir sebagai pemecah gelombang menguntung karena menggunakan material lokal. Sehingga permasalahan suplai material batuan dapat terselesaikan. Pengaman pantai yang berwawasan lingkungan sangat diperlukan untuk mengamankan pantai tanpa merusak pemandangan pantai. Oleh sebab itu penelitian ini melakukan studi mengenai perilaku stabilitas pemecah gelombang kantong pasir tipe tenggelam.Penelitian ini berbentuk pengujian model fisik 2-D skala lab, yang dilakukan di Flume Tank Laboratorium Jurusan Teknik Kelautan, ITS Surabaya. Pada uji stabilitas menunjukkan bahwa respon kantong pasir dipengaruhi oleh elastisitas kantong pasir, sedangkan elastisitas kantong pasir tergantung pada dimensi kantong dan kepadatan kantong. Ukuran kantong berpengaruh terhadap zona jepitan, dimana zona jepitan ini dipengaruhi oleh perbandingan panjang dan tebal kantong. Perilaku deformasi kantong pasir tergantung pada elastisitas kantong. Sesuai hasil pengujian, deformasi kantong pasir tergantung pada gaya yang bekerja pada kantong, jadi deformasi kantong dipengaruhi oleh kemiringan dan luas penampang kantong, sebagai akibat perubahan bentuk kantong dan jenissusunan. Jenis susunan SK1 mempunyai stabilitas relatif tinggi; struktur dengan kemiringan landai lebih stabil, dan bentuk kantong B1 lebih stabil dibandingkan bentuk B2 untuk susunan yang sama.
