<![CDATA[Gojek is an application that is very popular and in demand as a means of transportation because it is practical and fast. Consumer satisfaction is where the expectations, desires and needs of consumers are met. To assess whether the company provides quality service to consumers, it is necessary to evaluate consumers to determine the level of consumer satisfaction when using the Gojek application. This study aims to build a system for predicting satisfaction levels from Gojek Driver services to consumers using the Naive Bayes algorithm, as well as to determine the level of accuracy in classifying customer satisfaction using Gojek services. questionnaire is the method used in collecting data on Gojek consumer satisfaction. In this study, 120 questionnaires were distributed to respondents, namely Gojek service users, and these questionnaires would later become training data. Researchers use the survey method as a direct observation of the process of using Gojek services to identify the services provided to consumers. Researchers use the waterfall method as a system development model. This model is the oldest software development model paradigm, and the most widely used. The process of calculating the accuracy of the system uses the Naive Bayes method by testing based on training data taken from the questionnaire. The calculation results on the level of accuracy obtained from the training data are equal to 88.9%. The calculation is processed and divided by the system as much as 70% training data and 30% testing data or as many as 84 training data and 36 testing data. This consumer satisfaction prediction system can assist an admin in determining the classification of consumer satisfaction with web-based Gojek services by applying the Naive Bayes method.

<![CDATA[A fuzzy Logic Controller (FLC) is a control system that expresses in linguistics, there are several ways to defuzzification such as Sugeno. This paper proposes FLC to control the Motor DC Module position within -180 to 180 degrees using Real-Time Operating System (RTOS) running in the microcontroller. The FLC design based on input errors and changes of errors get from the feedback module, and defuzzification uses Sugeno rules. The FLC design simulates in the simulator program with the motor dc ideal model to show the output response transient. Experimental is done by using step input and variable inputs, step input is used to calculate the output response transient, and variable input to show the reliability of the control scheme. The output response shows that the motor DC control position has 0% of overshoot, 0.9 seconds of settling time, and 2.7769 rise time from position -80 to 0. The FLC success controls the position motor, and RTOS can be implemented in a microcontroller based on ATMega 2560 series.]]>

<![CDATA[Horror is a movie genre where the main purpose is to convey fear, anxiety, suspense, and such to the audiences. On ensuring the success of a horror movie, there is one big factor that decides it, which is color grading. Color grading is one of movies editing technique which main purpose is to change color in a video, useful to build or support a desired atmosphere. Color grading is important in horror movies because if the applied technique does not fit with the movie concept, the desired message to convey will fail to deliver. In this study, a two version of horror short movie will be produced, with one version using a darker color grading tone (A) and the other one uses brighter color grading tone (B). The method used in this study is Research & Development, with Research using semiotic analysis and Development using Multimedia Development Life Cycle (MDLC) method. The semiotic analysis will focus on 10 horror movies with a rating of at least 7 based on IMDb US Box Office Rating, and the analyzed subject is the color grading technique used on each movies. The color grading analysis result then will be applied to the short movie production. After the short movie production has been finished, a blind test will be carried out to see which version of color grading suits better with the movie. The blind test is carried out with 53 participants, and the result is 39 participants choosing A and the other 14 choosing B. Due to the significance difference, a reasoning was asked to the participants. Most of the participants who chose A said A fits more with the movie concept and for them B does not really convey the horror from the movie, while those who chose B just gave personal preference as an answer.]]>

<![CDATA[The Stream Cipher cryptographic algorithm is a cryptographic algorithm that can be used to secure symmetric key-type data. The Stream Cipher algorithm uses the same key when performing encryption and decryption. In carrying out the encryption process, the Stream Cipher algorithm uses the stream cipher method, where the cipher comes from the result of an XOR operation between the plaintext bit and the key bit. This study aims to implement the Stream Cipher algorithm with a Matlab programming language for text security. The text data used in this study is in the form of a file with a txt extension. The stages of research methods included literature studies, algorithm analysis, program design, and testing. The method used in this study is to apply the Stream Cipher algorithm to a programming language to produce an application that can be used for data security. The output of this research is the creation of an application program that can be used to secure text data so that the information contained is not easily stolen or misused by irresponsible people. The test results in the study using a key that was modulo-kan 65 first will produce a random message in the form of clear characters while using a key that is not modulated will produce a random message that is less clear in the form of boxes.]]>
