PANDANSARI LIGHTHOUSE

Pandansari Beach is located in the villages of Patehan, Gadingsari, Sanden, Bantul. This beach is located in other clusters of beaches such as Goa Cemara, Samas, Pandansimo and Kuwaru beach. The location can be accessed from Yogyakarta with a distance of about 30 kilometers. It takes around one and a half hours. Although access to this place is quite easy, public transportation, which can reach Pandansari beach, is not yet available. So it’s better to drive your own car or rent a motor vehicle.

The name Pandansari comes from the conditions around the coast. On the beach there are lots of wild Pandan. Although this beach is not as famous as other beaches, the condition of this beach is cleaner compared to other beaches around it. If you visit the beach in the morning, you will see people fishing on the beach. Tourists can also catch fish, but they must be careful because the waves are big and there are lots of coral.

Pandansari Beach is one of the beaches in Yogyakarta that has a lighthouse. The 40 meter high lighthouse has a circular staircase that can be accessed to the top. The lighthouse was built in 1996 and began to be used in 1997 as a sign and lighting for ships that sail at night.

WHAT IS A LIGHTHOUSE?

A lighthouse is a building specifically designed to emit light and functions as a navigation guide for ships at sea. Without a lighthouse, ships will have difficulty sailing at night and risk hitting rocks or dangerous objects.

HOW DOES LIGHTHOUSE WORK?

The way the lighthouse works is not as simple as reflecting light into the sea. The lighthouse works on the principle of reflecting vertical light onto a horizontal surface. This horizontal surface is affixed with a giant lens called a Fresnel lens. This lens reflects light in the form of light.

If the lighthouse is erected on a rock in the middle of the sea, the lens will rotate continuously in a clockwise rotation. Do not be underestimated, these lenses are very strong, you know! Thus, a beam of light will be easily visible even in bad or foggy weather conditions.

A LANGUAGE FOR SAILORS

Lighthouses mark reefs or dangerous areas on the coast. But the lighthouses do not only illuminate the approach to the coasts. They also allow sailors to find their way around. Each lighthouse has its own characteristics, its own way of illuminating the horizon. Some headlights emit sector lights, that is to say light beams of different colors: red or green to indicate dangerous areas, white to indicate the road to follow. Those which send only white light, can be fixed lights (constant and identical light intensity in all directions), flashing lights (periods of darkness longer than the periods of lighting), isophase lights (same dark and lighting times), or blackout lights (longer lighting periods than dark periods). To find his way around, all that remains for the sailor to do is determine what type of light is lighting him, count the durations of darkness and light and measure the rate at which these durations are repeated. By referring to his book of lights, where all the lighthouse codes are indicated, he will discover the name of the lighthouse that lights it and deduce its position in relation to the coast. Useful if the GPS or radar is down
