Classification of Types of Crimes Against Human Physique Using the K-Means Clustering Method

Rizkah Fadillah — 2025-01-30

Human physical crimes are unlawful acts and prohibited by the rule of law, which can harm or damage the body of others. This study aims to examine the number of groupings of types of crimes against human physique in 2019 to 2020 in all areas of East Nusa Tenggara province. To do this, we use the K-Means Clustering method to group the types of physical crimes against humans. The data used came from the Central Statistics Agency of East Nusa Tenggara province. The K-Means method is one of the non-hierarchical data clustering methods that seeks to partition data into the form of one or more clusters/groups. After the application of the K-Means algorithm in the grouping of types of crimes against human bodies in 2019 to 2020 in the East Nusa Tenggara region, there are 3 centroids, C1 for areas with low crimes, C2 for areas with moderate crimes and C3 for areas with high crimes. The initial centroid value is determined randomly and then for the next centroid is adjusted to the result of the calculation of the closest distance (minimum). The final results obtained are areas with low crime totaling 13 regions, namely East Sumba, Lembata, Sikka, Ende, Ngada, Manggarai, Rote Ndao, West Manggarai, Central Sumba, Southwest Sumba, Nagekeo, East Manggarai, and Sabu Raijua. There are 7 areas with moderate crimes, namely West Sumba, Kupang, South Central Timor, North Central Timor, Belu, Alor, and East Flores. As for the area with high crime, there is 1 area, namely Kupang City.

Sistem Pendukung Keputusan Pemilihan Security Officer Pada PT Kharisma Esa Unggul Menggunakan Metode VIKOR

William Dhaniel Tampubolon — 2025-01-30

A security officer is a security unit or security group established by a business entity to ensure physical security in the environment where they are assigned. The duties of a security officer include maintaining safety and order in their work area and surroundings, covering physical security. Security officers also act as sources of information, protect, and serve the public and surrounding environment. A security officer is a unit or group of personnel formed by an institution or business entity to carry out physical security as part of organized self-managed security within the work environment. The issue that arises in selecting security officers at PT Kharisma Esa Unggul is that the company conducts basic evaluations, primarily assessing skills and applying subjective judgment, meaning the company relies on relative impressions, assumptions, feelings, or preferences. A Decision Support System (DSS) is a system that plays a role in supporting the decision-making process in an organization or company. Therefore, for selecting security officers, each alternative must have criteria, and each criterion should have a predetermined weight, followed by a resolution process using the Vise Kriterijumska Optimizacija I Kompromisno Resenje (VIKOR) method for ranking. In this study, the result of the VIKOR method calculation showed that Aziz Marbun (A2) achieved the highest score of 0. The calculated ranking score for selecting a security officer ranges from 0 to 1. This approach helps the company make security officer selections in an accurate, efficient, and precise manner.

Data compression technology is the process of converting a set of data into a lower form of code. Compression techniques are usually used for data transmission processes, Data compression or data compression is a way in computer science to require smaller storage space, making it more efficient in storage. Boldi Vigna is an example of an algorithm for compression where both compress data by descending sorting each character. Implementation is the application or implementation, as an action to carry out the plans that have been made.

At this time, the increasingly rapid development of science and technology makes two-dimensional image files very necessary, where the resulting image size is large, requiring very large storage media, and other problems arise when exchanging data and information which increasingly consumes time and bandwidth. Therefore, a solution to the problem above emerged, namely by data compression. Data compression or data compression is a way in computer science to require smaller storage space, so that storage is more efficient. This is a compression method designed for grayscale images. The FELICS method presents a simpler system for lossless image compression that runs very quickly and only loses minimal compression efficiency. Implementation is the application or implementation, as an action to carry out the plan that has been made.

Learning is a process of interaction between students and educators and learning resources in a learning environment that includes teachers and students who exchange information. Learning is also a process to help students learn well. In the context of education, teachers teach a lesson so that students can learn and master the contents of the lesson to achieve a specified objective, can also influence changes in attitudes, and skills of a student, but this teaching process gives the impression of only one party's work, namely the teacher's work. ADDIE is an everyday term used to describe a systematic approach to learning development. In addition to the CBI, CAI, and other learning methods, the ADDIE method is also a method that is suitable for use in a learning system that will make it easier for teachers to deliver material. One way of computer-assisted learning is the application of the ADDIE method. The ADDIE method is one of the learning system design models that shows the basic stages of a simple and easy-to-learn learning system. In the computer-assisted learning process, where computers are used for the purpose of presenting learning in the form of tutorials, simulations, and games. This can really help students to be able to apply a learning system while playing which is very effective for the learning process for students.
