ANALISIS KEBUTUHAN ALAT BERAT YANG PALING EFEKTIF DAN EFISIEN PADA PROYEK SALURAN DRAINASE DI JALAN PIDADA, DENPASAR UTARA

Abstract

The Pidada area is an area of North Denpasar District with a high population density. During the rainy season, this residential area experiences flooding and it recurs every year. One of the areas where flooding often occurs is in the Pidada road area, which is thought to be due to the drainage system's performance not being optimal. This possibility is caused by reduced drainage capacity during the rainy season, increased water discharge, and sedimentation. Based on field observations, it was also found that the increasing conversion of agricultural land into residential areas without consistent addition or improvement of drainage infrastructure resulted in disruption of the drainage system in the Pidada settlement. From the calculations described in CHAPTER IV, several alternative combinations of heavy equipment requirements for drainage work projects in the Pidada road area are drawn as follows: From the results of calculating the productivity of the Komatsu PC 78 Mini Excavator, PC 75 Excavator and Hino 130 HD Dump truck, it was found that the heavy equipment productivity figures were: Komatsu PC 78 Mini Excavator = 41.4 m3/hour, Excavator PC 75 = 24.1 m3/hour, Dump Truck Hino 130 HD = 4,289 m3/hour. From the results of the combination of heavy equipment obtained in alternative 1, it is more effective and efficient than alternative 2, which can be concluded as follows: Alternative 1: Total Cost for 4 Days = Rp. 54,080,000, Alternative 2: Total Cost for 6 Days = Rp. 69,120,000.
