The construction of a complementary access road to the top of the dam is to the left of the Tugu dam pedestal. Based on geological studies, it is feared that there is a potential for seepage that passes through the left pedestal through joints, fractures, and fault areas/rock layers below the foundation surface. To anticipate this, the allowable seepage requirement is the lugeon value (Lu) < 3. This study aims to determine the geological conditions and the amount of seepage before and after foundation repairs are carried out using the grouting method. The type of this research is field research, qualitative descriptive because this research tries to collect lugeon population and cement material absorbed into the rock from water pressure test and grouting injection work by grouping each type of hole, pilot hole, primary hole, secondary hole, tertiary hole, and check hole. The study results by taking rock cores found that the constituent rocks were volcanic breccia units and colluvial rocks. Furthermore, a water pressure test before grouting with a water passing value of (k) = 6.62E-05 to 4.73E-04 cm/sec or with a lugeon value (Lu) of 5.07 to 36.21. After repairing the foundation using rim curtain grouting, the seepage that occurs decreases with a water passing value (k) = 1.96E-05 to 3.03E-05 cm/sec or lugeon (Lu) 1.50 to 2.32, so the requirements the target value of Lu < 3 was achieved with the effectiveness in the good category.

The slums in Sidoarjo city are caused by people who ignore the cleanliness of the environment. The number of people who dispose of waste, household waste, or production waste in the channel causes the reduced function of drainage channels. This study aims to determine the capacity of existing channels in the flood area of Sidokare and Lemahputro slum, Sidoarjo. The method used uses a quantitative descriptive method—hydrological data obtained from rainfall recording stations for ten years. The data was then analyzed using rational methods to calculate the discharge of flood plans when resetting the 10-yearly. The hydrology and hydraulic analysis calculation results obtained plan discharge (Qr) of 0.092 m3/s and existing discharge (Qs) of 0.032 m3/s. These results showed the existing channel condition could not accommodate the discharge of rainwater runoff, so there needs to be redimence of the channel. From the analysis of the dimensions of drainage channels conducted, obtained a new channel in the form of Box U-Ditch with a channel depth (h) 0.50 width under the channel (b) 0.40 m, with channel discharge plan that 0.128 m3/s can accommodate.

Construction management is very necessary in project management. To increase the efficiency and effectiveness of construction development activities, a unit price calculation tool is needed, namely construction cost analysis. Contractors generally make bid prices based on analysis that is not entirely guided by BOW (Burgerlijke Openbare Werken) analysis or SNI (Standart National Indonesia) analysis. Contractors tend to calculate the unit price of work using their own analysis which is based on previous experience in completing a construction work. The purpose of this study was to analyze the unit price of work on the building using the SNI, BOW and Field methods. The work components analyzed in this study are the unit price of materials and wages for partner work and foundation work. In each calculation method used, the most economical cost budget plan is obtained, namely using the field method calculation with the unit price value for the work of a partner, it costs Rp. 509.9996.78 while for foundation work it costs Rp. 722,965.1. By using the field method, a unit price is more economical when compared to BOW and SNI methods. So that these results can be used as a reference in planning the budget for a construction project.

Flooding is a problem that needs to be considered because it affects all sectors. The Bruno River in Kediri Regency often experiences flooding in the rainy season, although the overflow does not reach the settlements. But already, some levees in the Bruno river broke because they could not accommodate the discharge from the Bruno river. Such characteristics have the potential to be the cause of flooding. The core of the problem arranges various flood control efforts. The development of complementary infrastructure such as Water Resources becomes the right choice to overcome the flood event. This research aims to plan Water Resources to control the flood on the Bruno river, Kediri Regency. The analysis includes hydrological analysis and hydraulic analysis. The hydrological analysis includes rainfall calculations, match tests, and flood plans, while hydraulic analysis includes the calculation of bend dimensions. Rainfall data were obtained from kanyoran rain station for the past 10 years. From the rainfall data is done calculations and compared with estimates when re-from related agencies. So, the difference in discharge is known that is used as the basis of the analysis of Water Resources planning. The results of the study obtained flood discharge of 69,20762609 m3/s. ≈ 70 m3/s with a high bend planning bend 4.3m wide 30 m. The elevation of the water level downstream of the bend is +51.56 m so that the planning results can be used as a step to reduce flooding in the Bruno river.
