Abstract

Mushroom cultivation is a new source of food. The cultivation requires the control of temperatureand humidity to produce good quality of mushroom. Nowdays, there are many tools of automatic or manual temperature and humidity control system. However, they have many limitation in practical situation, such as difficulties in use and assembly. This research aims to design and make a better prototype of temperature and humidity control system, which can improve the productivity of mushroom harvest.The research method has two phases, that are conceptual design and tool and system design. The conceptual design phase includes need identification, system design, and component selection. The second phase are tools application and main system, includes microcontroller, sensor, heater, refrigerator, electronic circuit, hardware, the programming tool, and assembly of tools.The research produces a prototype of temperature and humidity control by using ATmega16 microcontroller, which increases the response time of temperature and humidity control, automatically controlling the system, easy to use and maintanance, and improve the previous system which is still manual control. The prototype is able to help the farmers to control the temperature and humidity in mushroom cultivation. The result from the application of the prototype indicates that it can increase the productivity of the mushroom harvest.

Abstract

Wireless Internet Media is wireless internet access which marks that the technology has become more advanced. Nowadays, mobile phones are not only used for communication but, can also accessing internet. Moreover, the discovery of the Wireless Application Protocol (WAP) enables a mobile phone (mobile device) to access a lot of information, one of which is information about the Digital Library (Digilib). Digilib are inseparable part of the students, because it provides a collection of informations that can be used by the students as a reference to support lectures in particular and education in general. Therefore, a student or those who come from the education world inevitably will use this Digilib services. Many Digilibs are supported by web-based services. However, not all users can access Digilib easily because of limited personal internet access, so this thesis gives a solution to build Digilib applications based on Wireless Application Protocol (WAP-based). The result of this research is to produce a design of Digilib with a variety of features, such as a detailed book review, book search, and a link to download the books. This application was built using the Wireless Markup Language (WML) as programming language and PHP using MySQL database.

For known email providers have differences the number of user. In recent years, user seems to use free email. It indicates that there are the most favourite email were choosed by user. This is because the email have more usable than others. The aim of this research is to propose usability characteristic of email and to get value from usability of email. This research methodology consist of five steps, such as: to clasify the atributtes to usability dimension, to determine criteria for usability atributes, to give value to use Fuzzy AHP, to normalize scale with OMAX, and to try measurement tool. This research result usability tools that have 3 dimensions, 24 attributes, and 11 criterias of email usability. Beside, it shows that effectivity dimension is the important dimension with wight 0,3996. Based on the resulting on try measurement tool kwon that the best email usability is Gmail with value 2,83.
