Abstract

In Indonesia, many users use electricity for light needs. There are two types of light sources, there is man-made light and there is natural light. The light source also only has two methods, namely turning it on and turning it off. No one can set the conditions for the light, in other words it has to be done manually. Therefore, the cause of electricity waste is manual use. In this case, researchers aim to create a control system for this light. With a system that is able to control the light control system automatically. Through a PIR sensor which will control movement to turn on the lights. The way it works is very easy, if there is movement the light will turn on.  Keywords: Arduino, System, Light

Abstract

Ease of communication creates a new need, namely securing information transmitted on the communication network from sender to receiver. One form of information sent is a picture. Easily sending information to various media often misuses data so that in this study the author will use the Steganography Technique, which is a technique and art to hide messages or information in a medium, such as text, images, audio or video which aims to avoid suspicion from people who not entitled to. This study utilizes a dynamic cell spreading (DCS) algorithm. The way the dcs algorithm works is that the message hiding is done by inserting it in the low LSB (Least Significant Bit) bit of the pixel data that makes up the file using a memory buffer as a temporary storage medium. The purpose of this research is to know how to design and analyze a data security application system with the steganography technique to hide data in video files with MP4 format using dynamic cell spreading (dcs) methods and to know the process of inserting data and extracting data in a video file with the format mp4. The results obtained are in the form of an application that can secure video files with the Mp4 format that can avoid data theft.Keywords: Data, media, steganography, algorithm

Abstract

Automated control of electrical devices such as lights or lighting plays an important role in energy management in various places. One of the best solutions to achieve efficiency is through automation of electrical devices. This automatic voice-based light control system uses the Arduino platform to manage the operation of lights based on user voice commands. Users only need to give voice commands such as clapping their hands to control the lights. The main purpose of this system is to facilitate interaction between users and lights, avoid the use of manual switches, and minimize the risk of short circuits. This research provides benefits in terms of saving resources, time, cost, and increasing the service life of electrical components. Keyword: C Programming Language, Microcontroller, Arduino Mega, Sound Sensor KY-037

Abstract

Cyber Harassment dapat disebut juga dengan pelecehan online dapat berupa mengancam atau melecehkan melalui email, pesan instan, media sosial atau memposting informasi secara online.  Kasus ini kerap terjadi di media sosial seperti salah satunya adalah Twitter.  Untuk itu dibutuhkan  sebuah metode klasifikasi yang tepat agar mengatasi kasus  Cyber Harassment dari data Twitter. Pada penelitian ini menggunakan bahasa pemrograman Python dan menggunakan dua metode yaitu Naïve Bayes Classifier dan Support Vector Machine untuk membandingkan metode yang memiliki akurasi yang baik dan mengetahui kinerja metode masing-masing. Pada metode Naïve Bayes Classifier menggunakan model Complement Naïve Bayes dan Support Vector Machine menggunakan model Support Vector Classifacation (SVC). Hasil kinerja masing – masing metode dengan pembagian data trainning dan data testing yaitu 80% : 20% menunjukkan metode Naïve Bayes Classifier dengan accuracy 86.30%, precision  84.51% dan recall 87.21%. dan Support Vector Machine dengan accuracy 89.56%, precision 83.62% dan recall 94.5%. Dengan demikian metode Support Vector Machine lebih baik dari metode Naïve Bayes Classifier dan dapat diimplementasikan untuk kasus  Cyber Harassment di Twitter.

Abstract

In general, official travel is travel undertaken by employees in a company that is related to official work duties. The official duties of the North Sumatra Province General Election Commission still use manual methods by recording documents in the official travel system. And they do not yet have an effective monitoring system designed to facilitate their activities, so that the official travel system does not run according to its development. The method used is waterfall because it has a design flow to find out directly the needs of the secretary, head of section, head of sub-section, treasurer to meet clear needs. With the design of this monitoring system, North Sumatra provincial KPU employees can search for official travel data easily and quickly. These functional requirements can be accessed by Admin, employees and officials.Keywords: Business trips, Monitoring systems, Waterfall.
