Abstract

Abstract :One of the problems felt by the people of Malang City is the problem of congestion and traffic system irregularities. Borbudur -Soekarno Hatta road, including roads that experience traffic problems, namely frequent traffic jams, especially at the time of departure or return to school, and hours of departure and return to work, this is because the road is the road access to the education area , trade and one of the access roads that lead to the center of Malang City. If this is not done immediately, the traffic problems will increase. A possible alternative to overcome this problem is to reduce motorbike users entering the road, by diverting some motorbike users to non-motorized bikes (bicycles) primarily for purposes of educational facilities, by providing special lanes for bicycles, which above the road (Sky Road). From the results of the analysis it can be seen that by providing a Bicycle Special Path above the Road Body (Sky Road), it can reduce the value of degree of saturation (DS) and can increase the level of service from C to B. Estimated cost of the main Sky road structure Rp. 9. 236,308 000 ,, - (Nine Billion Two Hundred Thirty-Six Million Three Hundred Eight Thousand Rupiahs) Keywords: special bike lanes, sky road, road performance

Abstract

Terdapat dua metode produksi beton readymix yang digunakan saat ini yaitu wetmix dan drymix. Pencampuran wetmix merupakan metode pencampuran beton yang memiliki produktivitas yang lebih tinggi dibandingkan drymix. Tingginya produktivitas tipe wetmix dikarenakan pan pengaduk pada pencampuran wetmix memiliki putaran mixing yang lebih cepat dari pada tipe drymix sehingga durasi pengadukan lebih cepat. Adapun perbaikan yang dapat dilakukan untuk meningkatkan produktivitas produksi beton readymix adalah dengan merubah bentuk batching plant serta memperbesar kapasitas hooper agregat agar dapat mengurangi waktu tunggu alat lain pada operasi penggunaan loader, sebab produksi beton pada aktivitas produksi berasal dari penggunaan loader untuk transportasi agregat.

Abstract

Parking is a condition of not moving a vehicle that is temporary because it was abandoned by the driver. Included in the definition of parking is every vehicle that stops at certain places whether stated by traffic signs or not, and not solely for the benefit of raising and / or lowering people and / or goods.Campus 3 Lumajang State Community Academy has facilities and infrastructure prepared by the Lumajang Regency government. However, the parking lots provided cannot accommodate vehicles optimally because of the ratio of the number of vehicles and the area of the parking area that is not appropriate. This is because the area of the parking lot is not analyzed by data error when measuring.Each measurement data is assumed to have errors both systematic errors, random errors, and large errors (blunders), so that in the measurement of parking lots certainly there are errors. From this the authors intend to conduct research to find out how the propagation of systematic errors and the large systematic errors of the area of campus parking lot 3 Lumajang Community Academy.The methods used in this study include preparing materials and tools, making land sketches, decomposing them, determining distances using theodolite, determining land area equations, and finding systematic error propagation. So that the final goal in this study is to find large systematic errors in the parking area of Campus 3 of the Lumajang State Community Academy

Abstract

      The work of embankment in the main dam with an upright core consists of 5 pile zones: the core, filter, random, rock, and rip-rap. There was difference in planning and implementation of embankment filling. Random and rock used quarry Bondrang in planning but blasting upstream of the excavated material was used in implementation. This difference is because there are social problems with the community surrounding the Bondrang quarry. The purpose of this thesis is to repair the dam foundation, to find out the seepage discharge, to analyze the possibility of piping, to determine the safety factor of slope stability in the dam, and to determine RAB Maindam of Bendo Dam Project Ponorogo.      The required data were of the geologic of the dam foundation, embankment materials, cross-sectional images of the dam body, and dam technical. Repairing the foundation using 3 methods : curtain grouting, consolidated grouting and blanket grouting; and for seepage calculations using the Cassagrande formula; to calculate safety figures using the Fellenius method and use the Geo-Studio 2012 application, the Seep / W program to find out the seepage discharge and the Geo-slope program to find out slope stability in maindam.      The analysis resulted in 3 methods of repairing dam:  curtain grouting with a depth of 39.83m, consolidated grouting with a depth of 5m, and blanket grouting with a depth of 15m; seepage discharge capacity <1% passing water average meaning safe; velocity seepage (7,3816 x 10-7m/sec) < velocity critical (0,004017m/sec) and 11,97  > 4 meaning safe for piping; >1.5 slope stability in various conditions without earthquake load meaning safe; 1.2 slope stability in various conditions with earthquake load meaning safe; the estimated cost IDR290,388,884,070.62 for main dam

Abstract

Gerigi weir was a modification of jigsaw weir, which the difference was in direction of curves. On jigsaw weir the curves were horizontally, but in gerigi weir the curves were vertically. The aim of this modification was sediment in upstream of weir could pass at certain speed of water. This research utilized open channel model. From this research would be known the possibility of gerigi weir in passing the sediment. Sharp weir would be used too as a comparison in flowing the sediment. In this research, some of different discharges were be used. Based on the observation, variation of the height of sediment on gerigi weir was more variable than on sharp weir. Ability to transport the sediment on gerigi weir was better than sharp weir.               Keywords: gerigi weir, open channel flow, sediment
