This tool system works automatically, which functions to feed the fish and detect the water turbidity. The fish that being feed and the water that is detected are in Aquarium or in Pond. Input for this tool are RTC (real time clock), Turbidity sensor and on/off button. To start or turn off the tool is used on/off button, to feed the fish automatically is used RTC component and to detect water turbidity is used turbidity sensor. Output for this tool is an LCD (liquid crystal display) display, Buzzer, Servo Motor and LED (light emitting diode) component. To display information in writing format is used LCD display, to sounding information in sound format is used buzzer, to move waterways door and foodways door is used servo motor and to indicate the tool is activated and processing is used LED component. The main component of controlling all component and program in this tool is Arduino Mega 2560. To make a tool program that will install in Arduino Mega is used C programming language for Arduino. By using this tool, will make activity in feeding the fish and detect turbidity of water be more effective, more efficient and easier than manually.

Solar-Cell panels function is to capture the energy of sunlight and then convert it into electrical energy. In this tool, Solar-Cell panels can move according to the tilt of the sun’s direction of motion so that the captured sunlight can be maximized. The electrical energy is used for free tourist facilities such as lighting, internet wi-fi, charging electronic devices, CCTV, and LCD. This tool will be placed in one of the tourist attractions in the city of Padang. So far, based on observations, tourists do not like to linger in tourist attractions because of the lack of free facilities for tourists. They cannot charge their gadgets, cannot access free internet, feel unsafe because there are no CCTV cameras and no audio-visual media. The purpose of this tool is made to increase the number of tourist visits to tourist attractions in Padang so that it can increase the PAD of Padang.

Healthy food menu for toddlers is selected based on criteria that have been determined by Puskesmas Sasak Ranah Pasisie. The selection of healthy food menus for toddlers is carried out by the institution as the selection of healthy foods for toddlers. The selection of toddler food menus still uses traditional methods that have not been systemized. With these problems, a decision support system is applied using the La Raelite Elimination Et Choix method. This method is able to give subjective and inuitive considerations of the criteria factors that are considered important influences on alternative choices. Decision Support System is a computer technology solution that can be used to support decision making that is complex in problem solving in an organization, in order to be able to determine the selection of the best competitive and superior healthy food menu from the many toddler food menus then the process of selecting a healthy toddler food menu that determines the optimal alternative is fast and efficient.

This study focuses on the creation of a novel algorithm for monitoring field data collection activities by field data collection officers from Indonesia's Central Statistics Agency (BPS) using web-based digital technology. This study aims to check the accuracy and veracity of data collected by the BPS data collection officer. In this research, 200 respondents were collected by 10 data collection officers of Indonesia's Central Statistics Agency (BPS) and monitored by 5 supervisors’ officers from BPS. Then the Head of BPS supervises process monitoring at a certain regional BPS office. We propose a novel algorithm that can be used with web-based digital technologies. The algorithm is developed by comparing data from the BPS office in the form of three variables that are a list of names of respondents, a list of questioners for respondents, and the location (area) of respondents with data from the respondent's NIK (ID Number), answers to respondents' questions entered into the system, and the GPS location of field data collection officers detected by the web-based system. This research employed a novel algorithm on web-based digital technology, increasing the accuracy and veracity of collected data. The score value of the respondent's name variable is 92 percent, the respondent's answer to the questionnaire variable is 93 percent, and the respondent's location variable is 95 percent. The data was evaluated by all field data collection officers, supervisory officers, and the BPS head.
