Likewise with features in the phone is increasingly sophisticated. Currently bluetooth version 4 is almost mandatory in all phones. Even for entry level phones are now equipped with bluetooth version 4. This paper discusses the use of Bluetooth Low Energy-which is part of bluetooth version 4, in providing information about the status of plant growth chamber conditions. By using this concept, all phones or tablets that have bluetooth version 4 and there are applications in it will be able to receive the latest chamber status. The results show that this way of broadcasting is very effective. The data required to be monitored by a laboratory technician can be continuously broadcasted so that anyone on duty will get instant information at his grasp.
Managing letters related to residence in Babau Village usually takes a long time. Residents must meet directly with the head of the RT/RW in the domicile area to obtain a cover letter, then they can go to the Kelurahan office to arrange the intended documents. The problem that then arises is if the community cannot meet the RT/RW leader because of busy life. Likewise if it arrives at the Kelurahan office, it turns out that the Lurah is not there. This will certainly hinder the management process. In addition to the above problems, another problem that can also arise is the RT/RW cover letter that has the potential to be falsified.These problems can be solved by building a Digital Village platform where the community does not need to meet directly with the RT/RW but can use the existing platform to manage the required documents. The proposal letter that goes to RT/RW can be directly approved and forwarded to the Village Head to be approved and ready to be printed. Everything is done without the need for paperless paperwork.
