Lomban Party in Jepara was a party for the fishermen in Jepara. As the time changes, this party now is done by the people of Jepara. This party becomes the highlight of Shawwal week. It is held on the eighth day of Shawwal month every year of Islamic Calendar. It is a week after the day of Eid Al Fitr. Jepara people often called it as ‘bakda’, ‘bakda kupat’, or ‘bakda lomban’. They called it bakda kupat because when it is the day, they celebrate it by cooking kupat, lepet and others delicious food like opor ayam, rendang daging, sambal goreng, oseng-oseng, etc. Kupat (Javanese) or ketupat (Indonesia) is not a new food for Indonesian especially those who come from Central Java. This food is made of rice packed up inside a diamond-shaped pouch made of a woven palm leaf. The taste is the same with rice in common. On the other hand, lepet and kupat is alike but lepet is made of sticky rice served with a salted coconut grated. Lepet tastes savory so we can eat it with no side dishes. It is 10 cm long and has a round shape. Besides cooking the typical food of Bakda kupat and lepet, people also cook snacks. The childrens are celebrating by wearing new colorful clothes and getting ready to the Kartini Beach. Kartini Beach is the center of crowd when Lomban Party is happening.
Some people said that the word Lomban derives from the word Lomba-lomba which means the time when the people was very joyful doing any sea competition which is still be done nowadays. Some said that the word derives from the word lelumban or having fun. These two derivations have the same meaning. They are having fun after having a full month of Ramadan fasting.
People prepare “ammunition” which is used in “Perang Teluk Jepara”. Perang Teluk Jepara is a series of Lomban Party. Ammunitions used are foods and beverages, and also “weapons” like ketupat, lepet, and kolang kaling. They also bring fireworks so that it sounds like a real war. The traditional boats depart with the back sound of kebogiro, a gamelan playing.
The firework sounds and the bullet break the ears. The kebogiro song is still played during the war. After it finishes, all of the participants land in Kelor island to eat their foods. There also many people who sell foods, beverages and also others needs. On the day before Lomban Party, all of the fishermen who participate in the party go to the tomb of Encik Lanang who is buried in Kelor Island.
Lomban Party nowadays is celebrated by not only the fishermen but also the people of Jepara. It can be seen by their enthusiasm for the preparation of the party. Two or three days before the party, markets in Jepara are becoming as crowded as the days before Eid Al-Fitr day.
