Abstract: The purpose of this research is to study the performance of early landslide detection devices based on arduino
microcontroller AT89S51. This is related to the frequent landslide hazards caused by high rainfall, improper
soil characteristics and soil tillage. Therefore it is necessary to preventive action is the existence of a tool that
is able to monitor or detect any cracks and soil instability that has the potential to landslides. This research is
carried out with a research and development approach. At the beginning of the study, the data needs analysis
of soil shifting parameters. The design of landslide detection devices is constructed based on research that
precedes and developed as needed in the field. Landslide early detection devices utilize extensometer sensors
(detection of ground shift), humidity sensors and vibration sensors and AT89S51 arduino microcontrollers in
the supply of electrical energy from the sun and equipped with GSM communication networks, and sirens as
a warning sign of landslides. The result of the design of landslide detection device can work well with some
limitations that is the maximum transmission signal coverage range of only up to 800 meters and soil moisture
sensor has a percentage error value of 2.89%. The test results indicate that the warning sign through the buzzer
will sound after 2.0 seconds from signal reception in the RX section, while the SMS gateway via mobile will
appear after 2.5 seconds from signal reception in RX. Solar cell as a power supply in the transmission (TX)
has a great benefit considering the location of TX is in the field, which is difficult PLN electricity but very
much got sunlight during the day. The result of converting solar light energy into electrical energy will be
stored on the akmulator / battery so as to provide energy requirements on the device at night.solar powered
for disaster mitigation.
1 INTRODUCTION
In landslide areas, risk mitigation must often face
problemsrelated to economical resources,
environmental impact and logisticissues. This is
particularly true for structural counter-measures,
whichaim at mitigating the risk by reducing the
probability of failure (bolts,anchors, piles etc.), by
preventing the landslide from reaching theelements at
risk (barriers, ditches, retaining walls etc.) or by
reinforcingexisting buildings. On the other hand,
early warning systems (EWSs) are an alternative cost-
effective means to reduce the risk with a low
environmental and economical impact. In some cases,
for instance when a landslide is so large that it cannot
possibly be stabilized, theycan even be the only
solution. Indeed an efficient EWS should comprise
the following activities. (DiBiagio and Kjekstad,
2007): (a) monitoring, including data acquisition,
transmission and maintenance of the instruments; (b)
analysis and forecasting, which can be done by using
thresholds, expert judgment, forecasting methods and
so on; (c) warning, i.e. the dissemination of
understandable messages alerting for the impending
threat; (d) response, concerning if people are able to
understand and how they react to the warning.
Therefore the need for landslide detection equipment
that has the ability from the side of monitoring,
forecasting, warning and response in detecting the
movement of the soil to obtain information as early as
possible. This paper examines the application
performance of landslide detection devices based on
AT89S51 arduino microcontroller using
extensometer sensor, humidity and vibration of solar
energy supply.
