<![CDATA[It has been successfully created a robot named "MAX". MAX Robot uses 2 (two) main sensors, those are ultrasonic sensors as sensors that detect an objects and LM35 temperature sensors as sensors to detect and monitor the temperature of the robotic machines. Both sensors are connected and controlled by ATMega328P microcontroller based Arduino Uno. The results of the readings from the temperature sensor on the robot's body will be displayed to the Light Crystal Display (LCD). The MAX robot is able to detect objects effectively at a distance of ±25 cm, then the robot stops and then turns in a certain direction by considering the distance of the object around the robot body. If a barrier is not detected, the MAX robot runs straight. In addition, the MAX robot is also able to detect and monitor engine temperature on its own and is able to automatically activate engine coolers when the engine temperature is above the set – point (hot) and non-active again when the engine is in normal temperature.]]>

<![CDATA[It has been successfully made design of a digital temperature and humidity measuring instrument using ATmega 328P microcontroller. The results of temperature and humidity data are measured using the DHT22 sensor which receives data signals in the form of temperature and humidity. Design of the instrument is placed in the same place as the reference instrument, namely in the instrument shop, then the results of the design of the reference instrument and instrument are processed into graphical form and proven using linear regression equations. The measurement results are displayed on the LCD keypad shield. The results of the instrument design calibration carried out on the reference instrument have a fairly good level of accuracy, namely for air temperature of 99.99% and humidity of 98.34%. From the results of the calibration carried out, it shows that the design of the instrument made has good validity (accuracy and precision).]]>

<![CDATA[A CCTV optimization system has been designed using PIR (passive infrared) sensor based on AT89S52 microcontroller. This device consists of several series of sensor circuit, AT89S52 microcontroller minimum system, stepper motor driver circuit, push-on circuit and alarm circuit. The working system of the room safety device is when the PIR (passive infrared) sensor detects the movement of the object, then the output of the sensor is forwarded to the microcontroller, the microcontroller will process and convey to the driver circuit to drive the stepper motors that moves the CCTV. The push-on circuit is connected to the microcontroller port for controlling the movement of the stepper motor so it won’t rotate beyond 180 degrees, and for the safety of the room, an alarm circuit is connected to the microcontroller port as an alarming sound generator.]]>

<![CDATA[Studies have been conducted to detect the intrusion of sea water in the Candikusuma village, Melaya District, Jembrana regency, Bali. Sea water intrusion is the ground water contamination in the soilto make fresh water into salt. To determine the presence of sea water below the soil surface be used geoelectric resistivity method because sea water has aresistivity 0.2 ?m. Geoelectric resistivity method based on Ohm's law, aims to find a variety of material sundera layer of soil based on the distribution of resistivity values??. By injecting current through two current electrodes the potential can be measured by the electro depotential. Variations of resistivity will be obtained If the distance of each electro demodified, according to Wenner configuration. Smallest space used for all tracksis 5 m. The experiment data analyzed with the Software Res2 dinv. From the Software Res2 dinv obtained cross-section2-D, which indicates the presence of sea water on track1 which has a length 80 m with a resistivity 0.291 ?m, the length of track2 is 150 m with a resistivity 0.257 ?m, the length of track 3 is 150 m with a resistivity 0.203 ?m and track 4 with alength of 150 m has a resistivity of 0.287 ?m. From the analysis of the Software Res2 dinv sea water intrusionin the village Can dikusuma ± 470 m from the beach. Starting from the coordinates to coordinate .]]>
