At present there are still many government offices, especially the tourism and cultural offices of the Thousand Islands, which do not utilize technology for employee attendance, resulting in frequent manipulation of attendance data. Manual presence can cause the tourism office to have to manually record a large amount of attendance data, and make the process ineffective and inefficient. Therefore, this study aims to discuss the Employee Presence System Design with IoT (Internet of Things) Based RFID Using NodeMCU ESP8266. So this research can facilitate the Department of Tourism for the present system of attendance for employees to be more effective and efficient and does not take much time. This system is integrated with the website so that when the employee makes a presence, the data is automatically saved directly into the website database. Database processing on websites using MySQL with the PHP programming language. From several tests, many types of cards can be read by RFID Reader, because these
Bella Frame ART shop is a business shop that is engaged in selling paintings, calligraphy, and frames. Until now, the promotion method still uses brochures, posters, and pamphlets, so shop owners need a lot of money to convey information to a broad target market. Storing the results of feedback, or messages from customers is also needed, in order to assist the store in making decisions in product marketing and customer service in the future. With the application of CRM in the website-based marketing information system at the Bella Frame ART Shop, data storage can be stored neatly and in detail, and delivery of product information to customers can be done more easily and quickly and is expected to help the store make decisions in marketing products and customer service for the future. In this study, the authors used application development methods, namely the waterfall and agile methods. Web-based information systems with the proposed Customer Relationship Management (CRM) method are systems that meet the needs and have the advantage of being integrated with systems related to marketing information systems. As well as using the waterfall method can help writers in the first stage of application development because testing is carried out after the application has been run while the agile method is used at a later stage so that it can cover deficiencies in the first stage of application development, namely requests for changing needs so that applications can continue to be developed despite requests needs change and application testing can continue at any time so that errors or bugs can be found more easily.Keywords:Information Systems, Customer Relationship Management, Website, Waterfall, Agile.
In this Digital era, Microcontrollers are now growing rapidly and are increasingly in demand in control system applications. Including Arduino Microcontroller, by using this Arduino trying to overcome a problem that often occurs in the Data Center space, namely the problem of temperature and humidity instability that has a major impact on data on each rack in the data center space. This problem occurs if the temperature is too hot or too excessive humidity which results in overheating so that it can damage data stored in the data center. To solve the problem, Arduino detects temperature and humidity using a DHT11 module that can detect clearly and accurately, and can display on the LCD screen, or display the results of temperature and humidity detection on a webbased Thingspeak application and the Blynk application that can be accessed via a smartphone. Internet-based of Things (IoT). With DHT11 processed by Arduino can produce an ideal temperature of 18 ° C - 28 ° C and humidity of 40.00% - 60.00%, and provide Notifications that will be sent to the blynk application if there are problems with temperature and humidity instability.
High rainfall in the rainy season can last about six months, this makes it rain continuously and cause an increase in the volume of water that has the potential for flooding. While the public does not get information or notice directly when it will happen. To anticipate these problems, the design of a water level monitoring system as an early flood detection based on IoT is considered efficient. The system will detect the distance of the sensor to the surface of the water, if the distance of the surface water approaches the sensor, the system will sound the siren as a sign of flooding. The system will display the alert status that occurs and the water surface distance in realtime.. From 100 data of water surface distance with ultrasonic sensors that have been tested, get 6 times the distance reading error. In testing of several water surface distances with sensors, the system can store all distance data into a database.
Pujasera Hangout Salihara is a company engaged in the business of serving food and beverages for the public. During the Covid 19 pandemic, there were many impacts, one of which was in the restaurant business sector. With the Fuzzy database method Tahani model and Simple Additive Weighting are used in determining the destination of the favorite food menu at the food court according to customer desires accurately, quickly, and easily understandable, helping the food court owner and tenant of the food court at the salihara hangout food court in providing food menu recommendations, the most popular drink menu and the highest and lowest rating of each food court in a week or a month. The method of Fuzzy database model Tahani and Simple Additive Weighting are applied in making a decision support system with stages determined by the researcher. The result of the Decision Support System is a system that can assist in making decisions that are carried out accurately and according to the desired goals. In applications that have been built, the results are based on the value of the degree of membership and the truth value of the calculation process in the application. Testing is done by means of the BlackBox testing.Keywords:Decision support system, Fuzzy database method, Tahani model, Simple Additive Weighting, Pujasera.
