Generally, the database access of a website lies in the user login. When the login data is not accompanied by security techniques, it is very easily accessible by other parties. One effort that can be done to solve the problem is to encode the login data of website users based on cryptographic technique algorithm. Triangle Chain Cipher (TCC) is one of the classic cryptographic algorithms that encode data doubly and generate keys randomly along the plain. The process of encryption and decryption are interdependent to be one of the advantages of this algorithm. This algorithm will be more effective when combined with the Cipher Block Chaining (CBC) operation mode that is widely used in modern cryptographic algorithms today. The feedback mechanism between the blocks in this mode of operation is the operating advantage. This study describes how to combine the mode of operation of block chaining cipher with triangle chain cipher algorithm so that cipher data login website generated more random and difficult to find its original meaning.

Security in the protection of sending messages is a matter that must be considered, because the more the development of the age, the more sophisticated the technology. So that security in sending messages and data communication should be of more concern. Therefore we need a method or algorithm that can protect the message to be sent to the recipient of the message. The algorithm that can be used in encrypting is Caesar Cipher, as a cryptographic coding technique for messages so that messages that look difficult to read and solve. As for the method of inserting messages on encrypted image media using the End of File (EOF) steganography method, which is the method used directly at the end of the file. In the work of securing techniques of messages on this system, using various sizes of images or images that will be inserted a coded secret message or encryption whose capacity is not much different from the photos or images to be used. The conclusion of this study is that the application of the Caesar Cipher Algorithm can be used as a message security technique even though the algorithm is so simple but the level of security is assisted by the End of File (EOF) method to insert the encryption results from the Caesar Cipher algorithm so that the security level it has is sufficient to protect message information to be safe from eavesdroppers or hackers of the message that is not responsible or as a protection of data held.

INA TEWS (Indonesian Tsunami Early Warning System) is an important part of the national disaster mitigation system, and a domestic technological innovation for tsunami disaster mitigation. In the assessment of technology development priorities, INA TEWS uses the Analytical Hierarchy Process (AHP) method and the Technology Readiness Level (TRL) method to assess the level of technology readiness. There are four criteria of assesment, namely urgency of need, financing, supply of raw materials, and acceleration of innovation. INA TEWS technology is divided into four technology components, namely Technoware, Humanware, Infoware, Orgaware. Based on the preferences of expert respondents, it shows that the most prioritized criteria at this time are supply of raw materials (30.9%), urgency of need (28.4%), financing (22%) and the last is innovation creation (18.8%). For the highest priority technology components are Technoware (42.5%), Orgaware (28.4%), Humanware (19%), and finally Infoware (10.1%). Technoware components are priority and top. As seen from the test results of various sensitivity chart analysts, the Infoware component looks the lowest of all other technology components. It seems that Infoware has not become the focus of attention for management in developing INA TEWS. For this reason, the Infoware component is encouraged to immediately meet the aspect of innovation creation criteria.

Many students experience fatigue due to lack of sleep which can be caused by a psychological conditions or bad habits. Lack of sleep can affect student’s performance academically and causes many illnesses, stress and depression. Students with fatigue causes students to not study well, increasing risk of academic failure and will lead to having low GPA. In this research, fatigue detection is carried out to find out which students are experiencing fatigue. In this study, an annotated video dataset was used with a total of 18 subjects acted drowsy and alert. Fatigue detection is based on mouth movements, therefore mouth annotation is used. Mouth annotation has 2 categories, namely annotation 0 which indicates a closed mouth and annotation 1 which indicates the mouth is yawning. Previous study proves ResNet50 has better performance than other pre-trained models such as AlexNet, Clarifia, VGG-16, and GoogLeNet-19. We also applied image augmentation which is useful for providing new image variations to the model in each epoch by changing the rotation, random shift, and random zoom. ResNet50 model is used to perform binary classification which has two outputs, namely mouth stillness and yawning. The results of the frame classification are evaluated using precision, recall and f1-score. By using ResNet model, the results of the classification of frames labeled 0 or mouth stillness, obtained a precision of 0.72, a recall of 0.88, and an f1-score of 0.79. Meanwhile, the frame classification labeled 1 or yawning has a precision value of 0.85, a recall of 0.65, and an f1-score of 0.74.

According to Law No. 14/1967 concerning banking principles, it is explained that financial institutions are all entities that carry out their activities in the financial sector. withdraw money from the people and channel it into the people. Financial institutions have large data on financial facilities. In order to improve the quality of information disclosure to the public, financial institutions require the application of financial facilities as a means to register the financial facilities they have. This financial facility application consists of two platforms, namely web-based and mobile-based, so that a mechanism is needed to process data transactions between different platforms and can support interoperability between systems. Web service is a standard used in conducting data transactions between systems, because applications that exchange data can be written in a variety of programming languages and run on a variety of different platforms. The financial facility web service is built using node js with asynchronous javascript programming language so that it has better performance in handling requests. In this study, the web service was built using a REST architecture that uses the HTTP protocol to exchange data. Tests have been carried out to see the results of the web service using insomnia software. The results of this study indicate that web services can be a bridge for communication and data transactions between financial facility search applications and can run well and are able to support interoperability between systems.
