Disability is one of a person's physical and mental conditions that can inhibit normal daily activities. One of the disabilities that can be found in disability is speech without fingers. Persons with disabilities have obstacles in communicating with people around both verbally and in writing. Communication tools to help people with disabilities without finger fingers continue to be developed, one of them is by creating a virtual keyboard using a Leap Motion sensor. The hand gestures are captured using the Leap Motion sensor so that the direction of the hand gesture in the form of pitch, yaw, and roll is obtained. The direction values are grouped into normal, right, left, up, down, and rotating gestures to control the virtual keyboard. The amount of data used for gesture recognition in this study was 5400 data consisting of 3780 training data and 1620 test data. The results of data testing conducted using the Artificial Neural Network method obtained an accuracy value of 98.82%. This study also performed a virtual keyboard performance test directly by typing 20 types of characters conducted by 15 respondents three times. The average time needed by respondents in typing is 5.45 seconds per character.

This Study aims to create a Falling Floor type of Rats Trap that can automatically catches and kills rats that enter the trap and then, it will send a notification to the user’s phone via telegram chat app also automatically set it back to steady state again once the times given to kill the rat is over by using a sensor while system is controlled by a microcontroller. The system consists several main components that construct the system, first Wemos D1 “a wifi connections ready microcontroller” that controls whole system, an ultrasonic sensor as the main input, it detects the range of the sensor from the rat that enter the trap, the exact range will be determined as the the right condition so that system says a rat is detected, servo motors that used as rat traps mechanic that move each exact part of rat traps, like moves the rat enter‘s door, moves the trap floor, and moves the fences insde the rat cage, and especially systems should be connected to an internet connection by the wemos D1, so that system can sends a notification to user’s phone if a rat caught by the system with overall success rate is 67%.

The problem that occurs in Sanjai Tourism Village is inadequate internet access. Internet access is fundamental nowadays, both in daily activities and in the context of promotional activities for Tourism Villages to attract visitors. One of the aspects of assessing the Indonesian Tourism Village Award is digital creativity. To make this happen, it is necessary to have internet access that everyone can enjoy, including the community, visitors, and the Tourism Village group (Pokdarwis) in the Sanjai Tourism Village. Therefore, in Community Service activities, a Wi-Fi Coin system was designed to improve internet access in the Sanjai Tourism Village. The Wi-Fi Coin System uses coins to access the internet. In addition, the Wi-Fi Coin system can be portable for use in the desired location. The method used consists of three stages: preparation consisting of a survey and needs analysis to obtain data on community needs, especially the Sanjai Tourism Village Pokdarwis. The implementation consists of system design, testing, and implementation. System design and testing were carried out at the Unand Computer Engineering Department. Meanwhile, the implementation was done directly before the Pokdarwis team and the Village Community. Trials and equipment handover to the Sanjai Tourism Village Pokdarwis marked the activity results.

The use of technology is fundamental in the digital era. Adjustment and transformation are essential activities to keep up with technological developments. One of the uses of technology is product marketing and promotion. Sanjai Tourism Village, located in Bukittinggi City, is one of the villages where marketing and promotion of tourism products are still carried out using conventional promotional methods such as through newspapers, radio advertisements, posters, and distribution of brochures. This method is still limited and cannot reach a broader scope. Therefore, to compete in the digital era, there needs to be a transformation of promotion and marketing of tourism products through the internet media using a website. Information about promoting and marketing tourism products can be done digitally and online using a website. The results of advertising and marketing tourism village products by utilizing the website can be spread and known to the public with a broader reach. Therefore, in the community service activities of the Unand Computer Engineering Department, the Sanjai Tourism Village website was built with a method consisting of several stages, such as coordination, surveys, design, website implementation, improvement, and submission of the website to Sanjai Tourism Village. Each stage has been carried out, and a website has been produced with features such as a homepage, profile, tourism products of various fields, news and activities, and contacts.
