Abstract :
The High buildings are one of the object that have a high probability of being struck
by lightning, given the geographical location of Indonesia, which is crossed by the
equator, which results in high rainfall and lightning strike intensity. Therefore it is
important to protect high-rise buildings with a reliable system. Pagoda Taman
Lumbini which is located in the highlands at an altitude of 1300 mdpl with a building
height of 46.8 m is place of worship that also contains a natural park with a land area
of up to 30,000 m2 based on PUIPP, NFPA, and NFC 17-120 standards included in
the building. with the level of protection needs level I, which means it really needs a
safety system. In this building, external lightning protection has been installed with the
type of Evo Franklin type 150 which in the calculation with the Protective Angle
method has been able to protect the entire building area with a protection area of
85140.75 m2. But besides that, for the results of grounding at the Taman Lumbini
Pagoda it is very high, namely at 11 ohms for measurement and 17.32 ohms for
calculations which are not in accordance with the PUIL 2000 standard, which is a
maximum of 5 ohms, so that when lightning discharges to the ground it is feared to fail
and cause damage. Efforts are urgently needed to improve this, such as by changing
the current of grounding electrodes with the tape electrode, in which a simulation of
the calculation is carried out to obtain a value of 4.64 ohms, it could also be by
changing the soil chemistry, or by embedding deeper electrodes. already exists, the
result of the simulation calculation is 4.89 ohms.
