Abstract

The science of steganography leads to a branch of computer science that is about hiding data information in media that cannot be easily detected. There are many types of media for steganography. The most popular ones are digital images. Along with the development of the science of steganalysis, there is needs of a way to add security to the hidden data. With steganalysis, one can easily reveal existence of hidden data in media files. Therefore, this study seeks to answer the need for securing the data. The program is an application that is useful for securing hidden data. The function of this program is to encrypt data that will be hidden using the AES cipher method. By converting hidden data into ciphertext, even though hidden data can be taken its form is still in the form of text that cannot be read without using the key used to encrypt. This process involves data that will be hidden to be converted into ciphertext first and finally steganography will be performed using least significant bits. Not only that, the program will also compress stego image. From the results of the encryption, steganography and compression trials, the hidden image data can be retrieved using the key used during encryption. The hidden data does not experience loss of information because the process is carried out lossless. The hidden data has been compared with extracted data and produces unlimited PSNR values.

Abstract

From the increasing interest of the people in Indonesia in the use of YouTube, this has triggered the emergence of content creators who choose YouTube as a medium for work. So that the content creators are competing to produce video works that can be enjoyed by YouTube users. Various methods are used by content creators to improve the quality of the video produced.The process carried out in this thesis is the process of processing raw data that has been collected from YouTube, before the training and classification process. The process of data preprocessing needs to be done to overcome the raw data that is varied and inconsistent so that it can affect the training process and the classification process. Data preprocessing conducted in this thesis includes Tokenization, Stopwords Removal, Stemming. The classification process is the process by which the classification algorithm is run on comments that are used as input data for comments.Applications used in scientific papers have succeeded in producing smoothing values, where the value shows that the comments belong to the classifications of positive sentiments, negative sentiments or non-Indonesian data.

Abstract

In the advanced era of globalization, fish care can be created using special system to monitor the aquarium. The system that  can be controlled via Android becomes one of the most comfortable to use. By using a microcontroller that is connected to the internet, it can monitor the aquarium using sensors in real time and automatically insert data into the database. Through the Blynk application, fish owners can adjust environmental conditions by entering desired requirements. You can monitor data obtained from sensors through a website that is directly connected to the microcontroller. The test is carried out in 2 different fish environments (no system environment and monitoring system environment).  The monitoring system in this study not only can monitors 4 parameters in the aquarium (feeding, water temperature, water level, and water pH) but also controls most of the parameters in the aquarium (except water pH). Based on the results of the study, the monitoring system environment has fish mortality rate of 20% with temperatures around 28 °C while non monitoring system environment has fish mortality rate of 50% with temperatures above 30 °C.

Abstract

Along with the increasing number of 4-wheeled vehicles (cars), problems related to the availability of parking spaces for cars have also increased. Flow in and out of the car that is not balanced with the capacity of the parking lot. This is because the drivers/visitors do not have information about the availability of parking space before being in the parking lot.In this study, a trial will be conducted to help resolve the problem by implementing internet of things technology at the entrance and exit gates of the parking lot, and detecting the availability of parking slots. Then use a digital payment system with QR Code media for parking payments. Implementation of Internet of Things that is used at the entrance and exit gates is to use infrared sensors to detect the presence of cars at the gate and servo motor to control the parking entrance gate. While Internet of Things technology to detect parking slots is to use ultrasonic sensors. The ultrasonic sensor will always detect and send the status of each slot on the server. Then for the payment system created, will use the QR Code media as proof of parking transactions. The entire technology and system will be integrated in an application, so that it is expected to help the problem of the availability of parking lots and simplify the parking payment process.
