Until now, there are still parts of Indonesia that have not received electricity. In areas that do not have electricity, lighting at night is done using senthir or thinthir lamps.
Ordinary flashlights are made in home home industry. The bottom of the lamp which is the fuel reservoir is made of glass so that the remaining fuel volume is visible. The middle part is a circle that is connected to the bottom. The wick is inserted into the center of this lamp. while the top is a cover of glass.
There is another form of senthir lamp, made from used bottles or cans with a wick made of t-shirt material. This type of flashlight does not have a glass cover. If the wind blows strong enough, the light of this senthir lamp will sway or even turn off.
The light produced by the flashlight comes from the burning wick. The fuel used is kerosene. Kerosene in bottles or cans will flow to the top of the burning wick slowly.
When compared to the light produced by 5 watt TL lamps, senthir lamps are much dimmer. But the flashlight is enough to help people who do not get electricity.
Unfortunately, in the process of burning the wick of the lamp, it produces black carbon which is commonly referred to as jelanga. Jelanga makes around the house dirty. In addition, the effects of jelang also damage the environment.
Currently, the flashlight is rarely used. In addition to lack of light, causing dirty, also because kerosene as a fuel is increasingly scarce.
Compared to the best in use, senthir lamps are still much sought after. This lamp, which has a unique cover glass shape, is hunted for decoration or souvenir. Many traditional shops or restaurants use sethir lamp ornaments of various sizes as lighting and decoration.
To hunt for unique flashlights, you can come to flea markets or second-hand markets and souvenir shops. Apart from the shape, what makes the flashlight unique is that it is not made in a factory, but by home craftsmen and the price is quite cheap.
