Hernawati Gohzali, Dita Maria Panjaitan — Sat, 17 Aug 2024 00:00:00 +0000

In the current film industry, the competition is very big. We can see it in online streaming content through the ratings obtained. Film itself is a visual work that is packaged as a product of public entertainment for a specific purpose. However, there are also many films that are considered not to meet the audience's expectations. Even the films presented are sometimes illegal or pirated films. We can also find out whether a film is recommended or not. The problem is that viewers rarely understand how to see recommendations or even provide appropriate film recommendations. This study aims to develop a film recommendation system model using a combination of K-Means bisecting and Collaborative Filtering. The film data used in this study comes from Movie-Lens which consists of 100,000 ratings from 668 users for 10329 film titles in 18 film genres. The training process consists of a cluster process with the K-Means bisecting algorithm and calculating similarity values with collaborative filtering (item-based and user-based). The testing process is carried out to calculate the system error value by calculating the Mean Absolute Error (MAE) value. The results of the study show that recommendations with bisecting K-Means and user-based collaborative filtering get lower MAE values compared to bisecting K-Means and item-based collaborative filtering.

Mosaic image is an image made from a collection of many other small images placed side by side, so that from a distance it looks like one big image. The use of this mosaic image varies, for example in digital image processing, in the context of image analysis, mosaic can also mean the process of combining several images with overlap to create one large image, for example in geographic mapping using satellite imagery. Then as a pattern creation in the field of design, mosaic images are used to create complex or abstract patterns, which can be used in decoration, architecture, or product design. Mosaic image is a combination of several images to get a wider view. One of the problems in mosaic image is in the image matching process, the right image matching can produce a better mosaic image. This study will compare the image matching method with RANSAC and SSD. The mosaic image of both methods was tested using objective fidelity criteria. The results showed the RANSAC method with an MSE value of 121.5820 and a PSNR value of 27.2821 dB, while the SSD method with an MSE value of 140.8373 and a PSNR value of 26.6436 db. The RANSAC algorithm is good for use in cases of mosaic images with feature-based methods, while SSD is good for use in cases of mosaic images with direct methods.

Hanafi Dana Bastyan, Putri Febi Utami — Sat, 17 Aug 2024 00:00:00 +0000

A musician, especially a guitarist or a bassist, is certainly familiar with digital sounds or tones. Almost in the current technological era, they also use technology in music. Currently, there are many digital music devices. One of them is the use of digital effects for guitars and basses. These devices very widely, from large to compact. Sometimes guitarists and bassists often have difficulty controlling them. This is because the design of the device is made minimalist, so that with the large number of preset tones available with a small number of controls, it will complicate their performance on stage. The use of digital effects requires a large storage capacity, therefore, the role of the digital effect is like a processor in the CPU. If so much storage is not controlled, then it is possible to forget the configuration settings. Therefore, control is needed as a support and a tool to remind the preset memory. Therefore, additional devices are needed to control the preset tones. This paper will discuss how to create a model to control preset tones in the digital effects they use. The goal is to make it easier when they perform on stage. With good control features, and the arrangement of the appropriate tone arrangement, guitarists and bassists will find it easy to manage the presets stored in the digital effect memory.

Good leadership helps maximize the use of resources to achieve organizational goals. Data shows that this comes from young people who are enrolling in colleges in the Banyumas area. The local government, from the village to the region, plans a way so that local arts and culture are not easily influenced by other cultures. This method is used by the local government to encourage young people at the college level to improve community activities and college student activity programs. When the organization looks less professional, this problem arises. This is caused by a number of main factors, including problems related to the vision and mission, especially in managing the organization itself. Organizations founded by young people can face various unique problems due to the dynamics and unique characteristics of young members. Based on the problems found in the previous situation analysis, it is necessary to provide counseling and guidance to young students. This is especially true for students who are members of groups and communities in the college environment. This community organization focuses on the context of arts and culture in the Banyumas area, Central Java. Solutions must be used to address problems to improve leadership in organizations managed by young people. The first thing we do is provide an important understanding of leadership in organizations, then we go into the content, namely about arts and culture in the Banyumas region of Central Java.
