Abstract

Rivers are one of the important water sources for life on earth. Both humans,animals and plants, all need water to maintain life. Rivers flow from upstream todownstream, moving from high places to low places. Microhydro, or MicrohydroPower Plant (PLTM), is a small-scale power plant that uses water power as itsdriving force, such as irrigation canals, rivers or natural waterfalls, by utilizing theheight of the waterfall (head) and the amount of water discharge. The Cianten Riverhas sufficient water potential throughout the year, reliable discharge, suitablecontours, and has been utilized for PLTM.Data collection techniques in this research include observation and data collectionin the field by observing and recording data on the area of each watershed and thearea of civil building planning. Several models used for hydrological analysis are theTank Model, FJ Mock Model, and Markov Lag 1 Model. Apart from that,researchers also carried out financial evaluations of Microhydro Power Plants(PLTM).The results obtained for the Cianten I PLTM scheme/layout include the dam andintake building, sand trap, waterway, headpond, penstock, powerhouse, and exhaustchannels (tailrace). The generation discharge that can be selected based on the plantfactor value is in the probability range of 35% - 55%. The Cianten I PLTM project isconsidered feasible to be realized if it is in a condition of normal value andincreasing benefits. Under normal conditions, financial analysis and sensitivityanalysis show the Project FIRR results are 9.88%, FIRR on Equity is 36.52%, NPVis IDR. 2,916,937,135, and a BCR of 1.03 with an investment payback period of10.87 years.

Abstract

Project management functions to oversee the process of implementing construction work from the start of the project until the end of the project. In this research, the strategy used is the project management optimization handling strategy which will dominantly influence the implementation of the Palir Kaliancar Road widening project for the 2022 Fiscal Year. The aim of this research is to find out the factors that cause delays in implementing the Palir Kaliancar road widening project not on time. using the SWOT method.To find out the SWOT indicators that most influence the success in implementing the Palir Kaliancar Road Widening project, Semarang City. This research uses the SWOT (Strengths, Weaknesses, Opportunities, Threats) method to systematically identify various factors to formulate dominant project management optimization in the implementation of the Palir Kaliancar Road Widening project for the 2022 Fiscal Year. By conducting literature studies and research surveys, data collection includes data primary and secondary data then continued data processing. In the results of the IFE and EFE analysis of the components of the Palir Kaliancar Road Widening construction project in Ngaliyan, Semarang City, a value of Strength 4.24 Weakness 4.22 Opportunity 4.34 Threat 4.14 was obtained. For IFAS, you get a value of 0.01 from the Strength value minus the Weakness value, while the EFAS value gets a value of 0.1 from the Opportunity value minus the Threat value.From these results, you can determine the coordinates in the SWOT matrix quadrants. So the results of this combination show the coordinates of the SWOT quadrant matrix which is located in quadrant I, namely the strategy between the strength factor component (S) and the opportunity factor component (O). So the strategy developed for the Palir Kaliancar Road Widening Project component in Ngaliyan, Semarang City, uses a Progressive Strategy.
