This antique straight keris is from the dapur Jalak Tilam Sari. The meaning of the dapur Jalak Tilam Sari is as follows: "Jalak" symbolizes a man as the head of the household, "Tilam" is a place to lie down, a place to rest or in a broader sense a place to live and Sari is fragrant. The meaning of Jalak Tilam Sari is to impart fragrant protection in the presence of God Almighty as well as fellow human beings. The concept of the expected master prayer for the keris Jalak Tilam Sari is that the owner as the head of the household who is responsible for the livelihood, along with the residents of the house who take care of the keris Jalak Tilam Sari, always have glory, happiness, peace and receive a good name, be respected by the people around him and always receive the protection of safety from God Almighty. I estimate the tangguh to be Mataram (1582-1749). The pamor is Ngulit Semangka. The pamor Ngulit Semangka is believed to be able to expand associations, be popular with everyone and make it easier for the owner to seek happiness. If we get along well with each other and are liked by many people, the door to happiness is basically wide open for us, because opportunities can come from anywhere. There are also those who argue that the stripe motifs on the pamor of Ngulit Semangka are like different roads/paths leading to a destination. It is a message that we should not allow ourselves to be discouraged from achieving our goals and hopes in this life. This dapur has a simple gandik. The ganja is mbatok mengkureb.
