STUDI KELAYAKAN PLTM CIATEN KABUPATEN BOGOR DARI SEGI HIDROLOGI DAN EKONOMI

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 to
downstream, moving from high places to low places. Microhydro, or Microhydro
Power Plant (PLTM), is a small-scale power plant that uses water power as its
driving force, such as irrigation canals, rivers or natural waterfalls, by utilizing the
height of the waterfall (head) and the amount of water discharge. The Cianten River
has sufficient water potential throughout the year, reliable discharge, suitable
contours, and has been utilized for PLTM.
Data collection techniques in this research include observation and data collection
in the field by observing and recording data on the area of each watershed and the
area of civil building planning. Several models used for hydrological analysis are the
Tank 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 and
intake building, sand trap, waterway, headpond, penstock, powerhouse, and exhaust
channels (tailrace). The generation discharge that can be selected based on the plant
factor value is in the probability range of 35% - 55%. The Cianten I PLTM project is
considered feasible to be realized if it is in a condition of normal value and
increasing benefits. Under normal conditions, financial analysis and sensitivity
analysis show the Project FIRR results are 9.88%, FIRR on Equity is 36.52%, NPV
is IDR. 2,916,937,135, and a BCR of 1.03 with an investment payback period of
10.87 years.
