Abstract

Streaming is a service that transmits video and audio over the internet. In this application, users can obtain video files such as movies by downloading or installing them through Android. However, downloading video files with a considerable duration can increase the usage capacity on Android storage, and sending such files may require a long time. To address this issue, it is necessary to compress the downloaded video files using one of the algorithms available in compression. Compression is a process of transforming a set of data into a code or symbol to save storage space and prevent the file size from becoming too large. Many algorithms have been developed in the compression process, one of which is the arithmetic coding algorithm. Arithmetic coding is a lossless compression technique, meaning it produces data that is identical to the original and does not lose information during compression and decompression processes. By using the arithmetic coding algorithm, the system achieves a Compression Ratio performance of (2.5), Compression Ratio of (40%), space saving of (60%), and Redundancy of (60%).

Abstract

PLN (Persero) is a state-owned organization owned by the majority of the public that has the capacity as a provider of electricity frameworks spread throughout Indonesia. The most common way to check customer complaints is by using the website in particular to provide information. Where this takes a few minutes to take care of customer complaints more quickly and accurately. So it can contribute with information to utilize websites that make information more coordinated with PCs which makes it easier to track information, process information, and report customer complaints quickly. This exploration provides an outline of the timeliness spent on filing customer complaints by utilizing a website-based framework. With this website-based framework, it will facilitate the process of inputting data for a more accurate information so that it can work in the most common way of finding and providing clearer information and all the data is more accurate, it can be formed according to customer wishes. One of the methods that can be used to measure customer complaints is the servqual method. This method makes a thorough evaluation of customer complaints,. The evaluation is completed in 5 components of administrative quality, namely: Tangibles (direct evidence), Reliability (reliability), Responsiveness (responsiveness), Assurance (assurance), Emphaty (attention). Customer dissatisfaction exists due to an imbalance between customer expectations and perceived service performance.
