Abstract

Aktifitas PKL dan kendaraan yang melakukan parkir pada badan jalan menimbulkan kemacetan lalu lintas dan berkurangnya tingkat pelayanan jalan. Tujuan dalam penelitian ini adalah mengidentifikasi dan menganalisis pengaruh keberadaan PKL dan parkir terhadap kinerja jalan. Metode penelitian yang digunakan adalah metode penelitian survey yang dilengkapi dengan observasi. Penelitian ini menggunakan data kuantitatif yang dianalisis dengan kualitatif deskriptif. Berdasarkan hasil penelitian, disimpulkan bahwa pada ruas jalan arteri, PKL dan parkir memiliki pengaruh yang signifikansebesar 0,026 terhadap DS dan 0,028 terhadap kecepatan, dengan kenaikan DS sebesar 14%, dan penurunan kecepatan sebesar 26%, hal tersebut juga terjadi karena pada lokasi penelitian terdapat U-Turn, lokasi tersebut merupakan jalan arteri 2 arah yang dipisah oleh median, serta perbedaan fungsi guna lahan. Sedangkan pada ruas jalan kolektor, keberadaan PKL dan parkir mempengaruhi DS sebesar 0,049 dengan kenaikan DS sebesar 7%. Sedangkan terhadap kecepatan pengaruhnya tidak signifikan sebesar 0,064, tapi terjadi penurunan kecepatan sebesar 7%. Pada ruas jalan lokal, keberadaan PKL dan parkir tidak berpengaruh signifikan baik terhadap DS maupun kecepatan, namun terjadi peningkatan DS sebesar 80%, dan penurunan kecepatan sebesar 10%,selain PKL dan parkir, hal tersebut juga disebabkan oleh volume lalu lintas yang secara langsung mempengaruhi hambatan dan kinerja jalan

Abstract

DOI:10.17014/ijog.9.1.61-69Shear strength parameters influence the bearing capacity of pile foundations, i.e. internal friction angle (ϕ) and cohesion (c). Soil parameters are affected by water content, which can be altered by climate change. Clay soils have high swelling and shrinking potential, caused by changes in water content, and this can affect the failure of foundations. Analysis of the influence of moisture content on the friction resistance of piles needs to be carried out, especially in clay soils. This research uses laboratory experiments to model four piles, with diameters of 16 mm. The pile group models are modeled in soil samples taken from three different locations, i.e. Tembalang, Pengaron, and Pingit, in Central Java. The samples were treated (soaking and drying) for one, three, and seven days. The USCS categorization of the soil samples were OH (organic clay with medium plasticity) and CH (inorganic clay with high plasticity). Friction resistance in piles within soaking conditions, decrease in proportion to an increase in moisture content. On the other hand, friction resistance increases under drying conditions. However, the friction resistance of the soil that had been treated (by soaking and drying) was not equal to the initial conditions.
