Electronic arm for vesa-2 replacing the human hand role in kemplang roasting process in palembang – Indonesia

A series of attempt is conducted to minimized the role of human hand in kemplangroasting, the traditional snack of Palembang - South Sumatra, Indonesia. Traditionally, the roasting is perform manually on an open charcoal fire. The negative effect on human health has become the main attentionin this matter regarding the spread of emissions gases, heat emitted and particulates generated. An equipment named PenghematEnergiVertikal (Vertical Energy Saver) or abbreviated as VESA-2 is already developed and improved. VESA-2 is an equipment made to accommodated the heat emitted, the gas and particulates generated from the charcoal stove to be streamed to a place that is safe from human breathand environment. The use of speed controller and switch relay to create reverse rotationand has already successfully imitate the human hand movement to roast kemplang. Geared DC motor is used to get the low output RPM and to facilitate the simple transmission system.
