Abstract

The method of construction determines the cost and the time required to complete a construction, as well as quality, safety and health (K3) and the environment produced at the end of the project. This study aims to analyze the cost and time required to complete a storey building, specially a floor plate using a fly slab concrete and compared with the conventional reinforced concrete. Analyz quality, K3 and environment produced from the use of fly slab concrete and compared with the conventional reinforced concrete. The method of this tudy is by re-calculate of the cost and time in construction of Polytechnic Building Madiun which was changed from using the conventional reinforced concrete into the concrete fly slab. The cost recalculation is done by recalculate both the unit volume and price. While the time will be recalculated using Microsoft Project. Quality analysis is done by reviewing the existing concrete quality in the Work Plan and requirement, then compared with the quality of the fly slab concrete. K3 and environmental analysis done by reviewing the application of the K3 and the environment at the project location then compared between the conventional reinforced concrete slab with fly slab concrete. Based on the analysis of the magnitude of the reduction of the cost of implementing development work Polytechnic Building Madiun using fly slab concrete is Rp. 16.740.000,00 or 3 % of the floor plate work using the conventional reinforced concrete. Execution time savings by using fly slab concrete is 12 days or 29 % of the total concrete work timefor second and third floor using the conventional reinforced concrete.The using of fly slab concrete does not reduce the quality of the concrete slab due to the quality of the fly slab concrete that used is higher than the conventional reinforced concrete quality. The using of fly slab concrete can to minimize the work accidents, beside that, the using of fly slab concrete can reduce the wood as formwork and casting the rest of the waste reduction project.

Abstract

The flood problem and inundation local often occurring in regions banyumanik, precisely in the intersection of Jalan Durian Raya. A limited drainage channels plus garbage and sedimentation blockage makes the water cannot flow when it rains. This leads to a puddle by the depth of between 10 - 15 cm for 1 - 2 hours. Therefore planning drainage the environmental from can overcome flooding and inundation on jalan durian. In planning, hydrological analysis is performed to seek discharge plan with program HEC-HMS. Acquired discharge flood plan of 39,6 m3/s with repeated periods of 10 years. Then to find out the effectiveness of existing cross section, rivers and drainage channels are modelled with program HEC-RAS. Cross section is planned by condition of steady flow. The result of reckoning using existing programs show a cross section rivers cannot accommodate discharge plan. Similarly with its drainage channels. Treatment done with increased capacity rivers and drainage channels. River cross section in the normalization with three types of cross-section (type I near the lower B = 7 m and H = 3, 5 m, midstream type II B = 6, 5 m and H = 3, 5 m, type III near the upper B = 5 and H = 3, 5 m). While cross section drainages deepened and assembly of a parapet to prevent the overflow.
