Phefferkorn is also known as the creator of the 'Indo Melati' flag and emblem. The flag represents communal pride and loyalty and overal peace and non-violence supported by signs of defensibility.
- The two tilted 'siku-siku' (tridents) and the 'golok' (sword) represent Indo people as advocates and fighters in words and deeds.
- The middle of the triangle is reserved for the 'kembang melati' (jasmine flower); the flower represents charm and beauty. This flower particularly symbolizes Indo women.
- The star on top symbolizes the brightness during a dark night and people that shine when times call for it.
- The symbol is enclosed by a 'padi' halm (young rice stalk) on the left and right side. This symbolizes prosperity and good fortune.
- At the bottom the word INDO is written in gold coloured capital letters
In 1931 at the age of 10 Phefferkorn started practicing Pencak Silat in Bandung, the Dutch East Indies. He became a prodigy and only Indo student at the Javanese Pencak Silat school of teacher Mr. Sumanto who practiced the style of ‘Setia Hati’. For 7 years he trained with Sumanto on a daily basis.
When WWII broke out Phefferkorn enlisted as volunteer and became an air force armaments mechanic and air gunner. The aging Glenn Martin bombers at the secret airport of Samazinda where he was stationed were no match for the modern Japanese war machine and on the 8th of March, 1942 he was made a POW. He managed to escape the Japanese prisoner camp and fled to the Preanger mountains where he joined other resistance fighters to engage the Japanese in a guerilla war. Despite the fact he was half Indonesian his blue eyes revealed he was not Javanese and he was caught during a razzia by the Kempeitai. Non of the other resistance fighters survived Japanese imprisonment. Phefferkorn barely survived himself and after Japans’ defeat in the war he only weighted 21 kilos.
Due to the revolutionary violence during the Bersiap period following Japans capitulation, he was initially unable to leave the prison camp, but was too frustrated with the fact that he had to be protected by Japanese guards that he stole weapons and escaped their protective custody. He survived the Bersiap period and vainly attempted to build a home for his family during the chaotic years of the Indonesian Revolution. In one of the last so called repatriation waves he left Indonesia for the Netherlands.
The Netherlands 1959-2010
Penniless Phefferkorn arrived in the Netherlands with a family of 7 children and only continued the art of Pencak Silat for his personal training exercises. In 1967 he started a small school in the city of Utrecht. Soon he established a second school and in the end ran 17 schools throughout the Netherlands. He became part of the "Council Of Elders" advising the Dutch Pencak Silat union, BPSI (Bond Pencak Silat Indonesia).
