Landslide is one of the most frequent disasters in Indonesia, especially in hilly areas, valleys, and volcanoes. Geographical conditions that are generally mountainous areas and have slopes make the soil unstable. As a result, when the movement of the land becomes easy to slide. Ground shifts and excessive water content are the main causes of landslides. The landslide disaster can cause many losses, such as to cause loss of life, can disrupt transportation facilities, damage agricultural land, and various other consequences. In this study used sensor MPU6050 and Soil Moisture and NodeMcu sensors to provide early warning of landslides. Linear acceleration is detected by using MPU6050 sensor and will define the ground movement based on the scenarios developed in this study. Soil moisture sensor detects soil moisture. The result of soil movement detection and soil moisture is stored in file storage. When ground detection and soil moisture is greater than 51%, the alarm alert is sent to the user's smartphone with a 100% success percentage.

This study aims to create a security system that can work when motorcycles are parked or are being driven. Most congenital motorcycle security systems work only when the motor is parked, such as the security of the ignition key and the handlebar lock. In fact, not infrequently theft is done by robbing a motorcycle that is being driven by owner. Then made a system using Arduino microcontroller platform, GSM SIM800L module and mobile device. The system created consists of three MODE, the MODE PARKIR, MODE JALAN and MODE MANUAL that can be selected through mobile devices with Bluetooth connection. In MODE PARKIR there are two sensors that detect the theft action, the vibration sensor SW420 and Voltage sensor. If the ignition key is successfully broken or there is a motorcycle on the motorcycle GSM SIM800L module will give notification in the form of SMS and phone call. For Roadside mode the motorcycle ignition system will be activated automatically and the owner can directly use the vehicle without having to manually activate the ignition. When the motorcycle is seized the owner can turn off the vehicle engine by pressing the Stop button on the mobile device and GSM module SIM800L will send the coordinates of the nearest BTS.

People in general have a desire to live a healthy life. One way to keep health is by consuming herbal drinks, one of them is known as jamu. Jamu which is commonly found is "jamu gendong" which is a home-based herbal product that is marketed in the form of liquid in the bottle. When buying jamu, the seller will mix various types of jamu by pouring jamu from each bottle into a glass according to the buyer's request. However, mixing several types of jamu is carried out using the seller estimate, so the dosage of several types of jamu to the glass will vary according to the pouring. The purpose of this research is to make a arduino Mega based automatic jamu beverage mixing system. This system uses an LDR sensor to detect the presence of a glass with a resistance value read by an LDR sensor is > 500 ohm and a DC motor can move by the stirrer. The selection of the jamu menu's is done by pressing the keypad button from the code '1' to the code '8'. After the menu is selected, the jamu will flow to the glass and the volume of jamu will be calculated using a water flow sensor that uses multiplier values. For the volume of 150 mL is used to multiplie factor 3.7 , for the volume of 100 mL is used to multiplie factor 2.9 , and for the volume of 50 mL is used to multiplie factor 1.2.

Disaster is a sudden event, such as an accident or a natural catastrophe, that causes great damage or loss of life. Disasters can occur at any time, therefore a mechanism is needed to evacuate out of the building during a disaster. Generally public facilities have provided instructions and evacuation routes outside the building. Based on the severity of the disaster and the evacuation capability of the victim, the evacuation strategy can range from evacuation as soon as possible, evacuate slowly, move to a safe location inside the building or take refuge in the available protection room and wait for the rescue team to arrive. The algorithm for finding the shortest paths can be used to determine the evacuation route. But this path is still static, if the route damaged in then the evacuation route would become useless. The time for the evacuation process can also increase if the condition of the evacuation route is not known whether damaged or not. The solution to solve this problem is to make a system that can help find the safest and shortest evacuation routes during emergencies. This system consist of microcontroller Arduino Mega to control the system and led for evacuation sign. The evacuation routes is determined by implementing dijkstra algorithm with priority queue to search the shortest path.

The wireless sensor networks (WSN) are increasingly implemented in air quality monitoring with real-time and high spatial-temporal resolution. In this context, current work aimed at designing and testing a cost- and energy-efficient WSN-based air quality monitoring system. The system was assembled principally by wireless sensors, solar cells, microcontroller and network communication. In addition, a new circuit for buck-boost converter was implemented for voltage and current regulations. On-field, testing the proposed air quality monitoring system outdoor and indoor showed efficient real-time readings for the concentrations of carbon dioxide (CO2) and total volatile organic compounds (TVOC). Furthermore, it provided data about ambient temperature, relative humidity and air pressure with good accuracy. In conclusion, our results suggest a reliable and scalable WSN-based system for monitoring ambient air quality.
