Abstract

Jalan Surodinawan terdapat berbagai aktifitas dari fasilitas-fasilitas yang dibutuhkan masyarakat. Dampak yang ditimbulkan adalah bertambahnya volume kendaraan pada hari dan jam tertentu terutama pada jam-jam sibuk. Tujuan kajian ini adalah untuk mengetahui kinerja ruas jalan serta pengaruh hambatan samping terhadap ruas jalan Surodinawan Kota Mojokerto. Penelitian ini dilakukan dengan membagi Jalan Surodinawan menjadi 3 segmen, metode yang digunakan yaitu PKJI 2014. Hasil analisa dari penelitian ini yaitu volume lalu lintas pada segmen 1 sebesar 1396,53 skr/jam, segmen 2 sebesar 1135,44 skr/jam, dan segmen 3 sebesar 1199,07 skr/jam. Hambatan samping yang terjadi pada segmen 1 sebesar 561,36 kejadian dengan kelas hambatan samping Tinggi, segmen 2 sebesar 187,14 kejadian dengan kelas hambatan samping Rendah, segmen 3 sebesar 169,87 kejadian dengan kelas hambatan samping Rendah. Kinerja ruas jalan Surodinawan Kota Mojokerto masih layak dengan nilai derajat kejenuhan pada segmen 1 sebesar 0,58, segmen 2 sebesar 0,49, segmen 3 sebesar 0,50. Dari analisa kinerja pada ruas jalan Surodinawan Kota Mojokerto dengan tanpa memperhitungkan hambatan samping, didapatkan nilai kapasitas maupun kinerja ruas jalan mengalami peningkatan. Fenomena ini menyatakan bahwa adanya aktifitas samping jalan berdampak signifikan terhadap penurunan kinerja segmen jalan di sepanjang ruas Jl. Surodinawan Kota Mojokerto. Besarnya penurunan kinerja pada segmen 1 sebesar 12%, sedangkan pada segmen 2 dan 3 penurunan kinerja sebesar 4%.

Abstract

One of the conductors of water flow is an open channel, which we often encounter for irrigation and drainage purposes. Flow velocity (V) in an open channel depends on several parameters, namely longitudinal slope, cross-sectional geometric elements and obstacles that occur along the channel. Longitudinal slopes and geometric elements can be directly measured in the field or planned. The resistance value varies greatly depending on several factors, for example the material used for the body of the channel and other obstacles such as the presence of vegetation along the channel (vegetation). The resistance value in the channel is expressed by a resistance coefficient number such as the Chezy, Strickler and Manning resistance coefficient. This research aims to determine the resistance coefficient value in open channels, which is influenced by vegetation. The channel roughness coefficient used is the Manning roughness coefficient (n). Observations were carried out on a prototype open channel made from river stone masonry with dimensions of base width = 0.3 m, height = 0.5 m and channel slope = 1 : 1 with vegetation variations of 0%, 25%, 50%, 75%, and 100% of the channel length. Flow velocity was measured using a Currentmeter with 5 measurements for each variation in vegetation percentage. From the results of the analysis and changes, it was found that there was a slowdown in the flow velocity along with an increase in the percentage of vegetation relative to the length of the channel. For normal channels/without vegetation, the value "n" = 0.025 is obtained which corresponds to Manning's "n" value for stone masonry channels. Meanwhile, for the percentage of growth of 25%, 50%, 75% and 100%, there is an increase in the "n" value respectively as follows; 0.031, 0.043, 0.058, and 0.062
