Temperature is a main factor for drying tea. Higher the temperature, the little more time needed for drying. We must not put the temperature as high as possible because there is an optimal degree for drying tea.

[Humidity Control for Drying Tea] When nights come, the humidity level is to high, affect the production process of drying tea leaves.

[Tempe aparoduction Bussiness Group] The humidity and temperature of the fermentation room is undefined. it need a control system and a notification to the android apps.

[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] 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.
