Abstract

Cerme District is located in South Gresik area which has an area of 71.73 km2. This area is located above the height of ± 4m sea level. While the slopes of the Cerme District are in the range 0-2% with a slope to the north. The land-use plan map of Cerme sub-district should be designated as an industrial area and residential area which is still inundated at several points. One of these puddles is in the left-hand cerme drainage system, especially in the secondary sub-catchment cerme kidul. The inundation height is between 20-30cm with inundation ± 2-4 hours. This final project can find out the results of the planned debit calculation using existing land use and land use plans, the difference in the calculation of the debit reaches 60%. While the calculation of canal capacity using planned land use can be known that 2 "safe" and 8 channel segments "need normalization".

Abstract

Kalidami river has a length of 4.2 kilometers with a stretch of channels from the Airlangga, Manyar, Kertajaya, to Kejawan Putih Tambak areas. Boezem Kalidami is located at the downstream of the Kalidami river which is also equipped with a pump house and a water gate. The Log Pearson III method produces a design rainfall of 127.38 mm / 24 hours so that the rainfall is very heavy. So that it will produce a maximum flood discharge of 40.3 m³ / s and when compared to the capacity of Boezem Kalidami which is only 49,440 m³, Boezem Kalidami will fill very quickly. Coupled with the total efficient pump capacity of only 15.33 m³ / s, Boezem is only able to accommodate the first 2 hours and an overflow of 1.58 meters from Boezem Kalidami's riverside at 2.14.

Abstract

Flood has always been expected in the rainy season at the Pakal District before 2019, where rainwater flows from Benowo channel to the Sumber Rejo channel and backwater flows from Lamong river to the Sumber Rejo channel. These water “attacks” from the two sides of the water bodies made Sumber Rejo flood every rainy season. In this analysis the maximum water flow rate in Sumber Rejo channel within the 20-year period (Q20) is 22,57 m3/second. To eleminate flood in Sumber Rejo channel, a flood pump station is needed to pump the waterflow from Benowo channel dan stop the backwater infiltrating from the Lamong river. Two flood pumps with a total flow rate of 6 m3/second are already installed and running at the moment, while the optimal capacity of this flood pump station should be 12 m3/second. A large water storage with capacity around 88.712 m3 is already built to keep the water elevation low enough to not overflow the Sumber Rejo channel.

Abstract

Kalibokor Channel is one of the primary channels in East Surabaya. This channel overflows during the rainy season. The inundation height that occurs is between 0-15 cm. Some of the flood-prone areas that the channel passes through are Manyar, Klampis, Gebang Putih, and JL. Arif Rahman Hakim. The Surabaya City Government built the araya pump house as a helper for the Kalibokor channel in order to reduce inundation on Jl. Arief Rachman Hakim and reduce the load on the Kalibokor pump house. The study was conducted by calculating the value of the planned rain and flood discharge, then analyzing the existing one and ending by recommending a new pump capacity design. The results of the analysis calculation obtained that the planned discharge entered the Kalibokor primary channel on the side of Jl. Arief Rachman Hakim is 18.56 m3/s while the existing capacity of the Kalibokor primary channel on the side of Jl. Arief Rachman Hakim can only accommodate a capacity of 16.6 m3/s.

Abstract

rainage channel designed to accommodate plans with precipitation data, safe based on the use of, land and the dimensions. channelDrainage channel in water catchment areas along a channel darmo satellite is one of infrastructures supporting functioning of an urban system in the city surabaya.Changes in land over the function of the green space into land settlement and trade services responsible for the runoff of the surface in several locations in the city of surabaya. The problem a runoff a surface that often happens when the rainy season resulting from increased discharge of water drainage channel water catchment areas in the rain along a channel darmo, satellite causing the need for a study to analyze the performance of drainage channel. The data used in this study is secondary data, namely: the last 10 years of rainfall data obtained from rain stations (gunungsari rain stations, simo, and cages) and drainage channel data. While the methods used are hydrological analysis, arithmetic methods, and gumble methods. The data obtained is then analyzed to find out the plan discharge and drainage channel capacity. The analysis conducted in this study includes hydrological and hydraulic analysis. Hydrological analysis includes: 1) calculation of planned rainfall with Gumbel distribution with a re-period of two and five years, and 2) calculation of plan discharge using HSS Nakayasu.

Abstract

Embankment dams based on the grain size of the embankment material used are divided into 2 types, namely rock filled dams and earth fill dams. The Beringin Sila Dam is a random and rock fill dam with an upright core which is in the process of being built by stockpiling materials such as stone, gravel, clay, and soil. Blasting is an activity of breaking up a material (rock) using explosives or the process of an explosion, in blasting one of the important things that must be considered is the fragmentation of rock resulting from blasting. The method is carried out by observing the realization in the field and analyzing project data. The purpose of this study was to determine the productivity of heavy equipment, to analyze the realization costs of excavation and heap of blasted rock at the quarry location. The results of this study indicate that the productivity of drilling tools for drilling tools, with the Crawler Rock Drill (CRD) tool, it gets 5 holes/hour, while with the Hydraulic Crawler Drill (HCR) it gets 4 holes/hour. Productivity of loading and unloading equipment on excavation work and blasting heaps of rock at the quarry location, with an average of 25 units of transportation equipment and 4 units of CAT 330 excavator as loading equipment. For loading equipment, the production yield is 41.40 m3/hour, while for transportation equipment the production yield is 6.62 m3/hour. The realization cost for excavation work and rock heap from blasting at the quarry location in July – September required a cost of Rp.11,124,373,500.00 including the cost of wages, materials, and tools.
