| dc.description.abstract | The research about risk management in PDAM study location in PDAM Pekalongan City,
Central Java. The WSP-Operator begin with: (1) intake, (2) water treatment units, and (3)
water distribution units. Hazard events that may occur in drinking water quality are analyzed
by laboratory tests through sampling in the supply chain, water treatment installations, and
household connections as the basis for developing the FMEA Methodology. Development of
FMEA Method done by aligning indicators and sub-indicators of severity which is happened
related to 4K (Quality, Quantity, Continuity, Affordability) by adding Delphi Method. The
results of the Delphi method questionnaire show that the most important physical quality sub indicators of quality susceptibility are odor (108) and turbidity (100), chemical quality
susceptibility sub-indicators are industry (94) and agriculture (62), biological quality sub indicator susceptibility is bacteria (64) and worms (48), susceptibility to quantity of water loss
sub-indicators (104) and regulation (96), vulnerability to continuity of pressure sub-indicators
(94) and vulnerability to affordability of production cost sub-indicators (66). The FMEA method
can see the level of severity, the level of probability of occurrence, the level of detection, and the
level of authority so that it can produce a Risk Priority Number (RPN). The results of the RPN
at peak hours of water use with the lowest value is 2700 for the danger of "unavailability of
minimal coagulant stock" while the highest is 213.920 for the danger of "stone and river sand
mining". Thus, PDAM Pekalongan can take appropriate and sustainable alternative hazard
control or hazard mitigation measures. | en_US |
