Abstract

Television media is an information technology that displays images and sound, where television is a communication medium that provides various updated information and disseminates it to the public. At this time there are so many television stations that there is increasingly competition among television stations to provide interesting programs, these television stations are competing in terms of providing innovation and information and there are those who compete only to attract the public's attention so that the television station's programs get attention. high rating to seek its own profit. To overcome the above problems, a decision support system is needed where the method uses the Analytical Network Process (ANP) method, which this method is used because it can provide the best decision based on the highest value to the lowest value and will provide recommendations to the public which television stations can be recommended as worthy. watched by the public according to the needs of the community. From the calculation results, it was found that RCTI  had a value of 0.3775, SCTV had a value of 0.1954, Indosiar had a value of  0.1770, TV One had a value of 0.1363 and Kompas TV had  a value 0,0325

Abstract

At this time there are so many Internet packages provided by companies in the telecommunications sector to help facilitate Android users in accessing the Internet. Android users using this Internet package are for the purposes of social media, chatting, browsing, streaming and downloading where Android users will feel incomplete if they do not use the Internet package because in terms of finance it is most cost effective compared to using regular pulses. The Internet is currently one of the main alternatives in meeting all needs, namely Information and Education needs that provide positive value for all people. The number of operators offering Internet packages will certainly make it difficult for consumers to make the right choice according to their wishes and criteria. To overcome these problems, a system is made that will make decision making easier for choosing an Internet service package, one of which is the decision support system to help the community choose the best Internet service package. The method used in this study is the ANP Method. With the ANP method, it is expected to help the community in determining which alternatives will be chosen as a final decision in the selection of Internet Packages as needed

Abstract

AbstractDigital Image Processing, known as Digital Image Processing, is a scientific discipline related to techniques for processing an image using a computer. There are several types of images, namely color images (RGB), grayscale images (grayscale), binary images (monochrome) (Akhmad Fadjeri et al, 2023). In the world of medicine, image segmentation is used to detect an object in a medical image or analyze the nature of a disease such as eye disease (keratitis) (Kon et al, 2023).Image is a representation or can also be said to be a picture, imitation, imitation, or similarity, of a particular object. Images, when grouped based on the type of data that makes up the image, are divided into 2 types, namely analog images and digital images (Yao et al, 2022). Analog Images and Digital Images Analog images are produced using analog tools, such as analog video cameras, CT scans, analog photo cameras, x-ray sensors for thorax photos, cams, short wave sensors in radar systems, ultrasound sensors in ultrasound systems, and others. -other (Tarpley et al., 2021).

Abstract

The concept of cryptography has been used since ancient times by Julius Caesar and continues to develop today. Based on the era, cryptography is divided into two parts, namely classical cryptography and modern cryptography. The similarity between the two is that they both use mathematical concepts in the technique of creating and breaking a message. But in classical cryptography, the mathematical concepts used are still very simple, such as substitution, permutation and transpose. Meanwhile, in modern cryptography the mathematical concepts used are no longer simple, such as polynomials, prime numbers, groups, rings and fields. The advantage of classical cryptography is that it is easy to encrypt messages, but some encryption techniques also have a fatal weakness, namely that they are very easy to crack. An example of classic cryptography that is very easy to create and solve is the Caesar Cipher which only has 26 possible keys. Caesar Cipher is included in the Substitution Cipher encryption, where a random code or script is obtained by replacing each character in the original text.

Abstract

Much research has been carried out on medical image processing by developing various methods of image processing. The research was carried out with the aim of improving image quality, so that it is easier to interpret and analyze images objectively. The same is true for CT scan images of the lungs, which are images in DICOM (Digital Imaging and Communications in Medicine) format which were researched using the Active Contour method to be able to segment the borders of the lungs and be able to calculate the size of their area and circumference more appropriate. There were 5 CT scan images of the lungs used in this research as examples of segmentation using the Active Contour method. The results obtained from detecting CT scan images of the lungs based on validation of the suitability of calculating the area and circumference of the lungs by doctors have an accuracy of 80%. Based on this research, it can be used as a medical reference for determining the size of the area on CT scan images of the lungs.

Abstract

PT. Cemara Saringan Medan, a medium-scale manufacturer of palm oil filtration components, continues to experience frequent machine downtime and performance inefficiencies that disrupt production stability and increase operational costs. To address these challenges, this study aims to enhance machine reliability and productivity through the implementation of Total Productive Maintenance (TPM) integrated with a web-based monitoring system. Using a waterfall-based research methodology, the study involved data collection, preprocessing, TPM computation (availability, performance efficiency, and quality rate), OEE analysis, UML-based system design, application development, and black-box testing. The results show that the company’s production machines achieved an availability level of 89%, performance efficiency of 83%, and a product quality rate of 96%, indicating that productivity losses are primarily attributed to breakdown-related downtime and cycle-time inefficiencies rather than product defects. The integration of TPM with digital monitoring further demonstrates strong potential to enhance maintenance transparency, reduce human error, and support more responsive decision-making. These findings imply that adopting web-based TPM tools can significantly improve operational control and serve as a scalable foundation for predictive maintenance in medium-scale manufacturing environments.

Abstract

Wifi.id merupakan layanan internet publik yang berbeda dengan IndiHome yang melayani pelanggan perorangan. Dalam penanganan gangguan, koordinasi masih dilakukan melalui grup Telegram, di mana admin membagikan nomor tiket dan teknisi mengonfirmasi tugas secara manual. Sistem ini memiliki kelemahan karena data teknisi dan waktu penanganan tidak terdokumentasi secara resmi. Untuk mengatasinya, dirancang aplikasi pelaporan gangguan layanan IndiHome berbasis Android dengan pemodelan Use Case Diagram, Activity Diagram, dan Sequence Diagram. Sistem ini dikembangkan menggunakan bahasa pemrograman Java dan Firebase Realtime Database untuk meningkatkan efisiensi pelaporan dan dokumentasi data di PT. Telkom Gaharu.
