[Tempe aparoduction Bussiness Group] When the outdoor condition is very cold, they use a room to process the fermentation. The humidity and temperature of the room is undefined because there is no device to control the temperature of this room.

[Tempe aparoduction Bussiness Group] Optimal temperature for fermentation is 25 ° C –37 ° C with the best relative humidity at 70-80%. We propose to make a incubator based on Arduino in order to control lamps and fan.

[Villagers] Power output is the main idea of this system so we need to control the power voltage. It aims to optimize the maximum effective output power and turbine speed.

[Villagers] Since the main problem of the river is the flood during the rainy season, we need to overcome this problem not only using traditional sluice but using the now days tech of sluice.

[Villagers] No electricity to light up their village at night. The river flow in this village have the advantage of never dry during the dry season, we choose the hydro vortex with extended Kaplan turbine for the tech, this can generate electricity.

[Research Institute for Tea and Cinchona] Humidity is one of the main concerns in drying tea. The right humidity that good for the tea is around 60-70% with the temperature around 25 Celsius to 27 Celsius. (using hot blower that can be maintain using IoT)

[Research Institute for Tea and Cinchona] Rotor must not overheat or the machine will be down. The rotor must have a monitoring device. Each rotor in the machine does not have sensor to know how many rotations per minute (RPM).

[Chambre d'Artisanat] The craftsman sits on a low chair, close to the floor, with an uncomfortable and tired sitting position, where he uses both hands, resulting in a lack of ergonomics, especially that the fabrication process can take quite a long time.

[PT. Nusa Palapa Gemilang] As chemical-based fertilizer company, smoke and raw materials can pollute the air inside the company. Information on air condition is needed.

[PT. Nusa Palapa Gemilang] Information on energy consumption is only provided on a monthly basis. The company can’t decide whether their consumption levels are normal or excessive. It is necessary to monitor electricity usage in several areas.
