Population growth has a significant impact on transportation demand. With proper road
infrastructure, these traffic activities will go smoothly. As an important mobilization channel,
roads must be able providing safety and comfort for users. The solution to good service also needs
good paving materials. However, in combination with modified connecting materials, the paving
material becomes even better. By using mechanical empirical method of the KENPAVE program,
the average daily traffic data was used for analysis to find the pavement thickness, asphalt
stiffness modulus (Sbit) value, mixed stiffness modulus (Smix), and predicted road damage, and
then transfer function is performed to reach an acceptable number of lanes to receive a
representative load. Based on the results of the analysis, it is possible that the mixture of Asphalt
Concrete Wearing Course (AC-WC) with Starbit E-55 and Pen 60/70, showed the first signs of
permanent damage to the road structure. Deformation damage is 37,645,893 ESAL on Starbit E 55 and 37,174,111 ESAL on Pen 60/70. In terms of performance, the blend of AC-WC with Starbit
E-55, compared to the blend of AC-WC with 60/70 rods, can overall withstand higher loads in
terms of damage parameters. The mixture of AC-WC and Starbit E-55 is known to have
advantages over its performance, so based on the results of this analysis, use of a mixture of AC WC and Starbit E-55 is recommended as an alternative or solution to the maximum dramatically
reduce the risk of road damage and increase the service life of the road surface.

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.
