Abstract

Abstract: Krakatoa volcano was erupted at 1883 which lead to tsunami and 36417 people died during this disaster. Now a days, it’s volume growth rapidly and named the Anak Krakatoa volcano. This volcano is one of 129 active volcanoes in Indonesia. It is very important to monitor the volcanic activity such as identified of soil temperature gradient as one of the important parameters for predicting volcano eruptions. In this research, furthermore, we had develop system monitoring of soil gradient temperature used mini single board computer BCM2835. Sensor DS18B20 was used to measure the temperature. Data temperature was sent by SMS technology and recorded into data base server. The system has a report activity and can be accessed through web application, early warning system was also implemented, system will sent SMS notification if there any critical event founded during measurement. Modified waterfall model was used for software development life cycle. The result of gradient temperature monitoring shown that at depths of 30, 60 and 90 cm, temperature ranged was between 25-32°C, the deepest sensor position has highest temperature and at nearest surface has lowest temperature.
