Development of middleware that has been done in previous research which refers to interoperability problem. Interoperability issues are raised that refers to the development of middleware in order to connect devices that use different protocols namely CoAP, MQTT and Websocket protocol. Tests on the previous studies used DHT22 and nodemcu as sensors. The result was that node sensor and IoT can communicate well with delay parameters, packet loss and overhead of each protocol used. The previously developed IoT Middleware aside from the idea of ​​syntactical interoperability, is also developed with the aim of semantic interoperability, where semantic interoperability is the process of sending data that refers to the content and context of data sent. However, previous studies of middleware testing were limited to syntactical interoperability, where in this study semantic testing will be done, with data structures sent differently than usual and data sent in the form of images, animated moving images and video. Based on the test results, the middleware is able to receive the data, with the results. At the time of transmitting images with resolution 1360x768. The lowest obtained delay is in QoS 2 and the highest in QoS 0.002993 seconds. When transmitting images with 1024x768 resolution. The lowest obtained delay is in QoS 2 and the highest in QoS 0.003959 seconds. When transmitting images with 800x600 resolution. The lowest received delay is in QoS 2 and highest on QoS 0.006523 seconds.

Credit cards are one of the most popular and many used payment methods on online transactions. In line with the large number of credit card users and even become a daily payment method, the security in verifying every transaction is also very important to be improved. Data mining is one of the most method that can assist in solving problems in credit card transaction security. This research purpose to design a verification system of credit card transactions, which can help the banks in knowing the possibility of fraud that occurred. This research uses support vector machine (SVM) method to detect fraud based on outlier / anomaly on transaction data.Sample data of 100 rows, using attribute of account number as label, month, and transaction nominal as training data. Testing is done by simulating a transaction on the form, by filling in the account number, month, and transaction nominal. The system will detect whether tranksaction with the account number is entered in the designated in the model class. If out of the class then the transaction is suspended.

Urban people who have high mobility are starting to realize the importance of better environmental health by reducing air pollution so that they can reduce high stress levels. Being in the house, does not mean avoiding air pollution. According to the EPA (US Environmental Protection Agency) or environmental protection agency in the United States, indoor air pollution is 2-5 times greater than outdoors. Then came the biophilic trend for urban communities by making their homes a comfortable and healthy place by using live plants as a lifestyle because they nourish the body both physically and psychologically. Limited residential areas such as apartments are starting to become the choice of urban communities because of good security, complete facilities, and easy parking and strategic locations. The problem of small residential land in apartments is a problem for users, so they tend to choose to use multifunctional products. The limited land also makes it difficult for the residents to channel their hobby of maintaining plants and pets, as a means of recreation and entertainment. Researchers try to analyze the need for multifunctional furniture that can channel the hobby of raising animals and plants, namely Smart Aquaponics; by not taking up a large space, having an attractive design and complete with automation features. This smart aquaponics research was conducted for apartment users who need a good living environment but have limited time to maintain it. This study tries to apply an automation system in Smart Aquaponik products that can help apartment residents to be able to have functional furniture that accommodates a biophilic lifestyle.
