This study aims to optimize the implementation of the K-Nearest Neighbors (K-NN) algorithm for medical image classification by focusing on selecting the optimal KKK parameter and applying dimensionality reduction techniques to improve accuracy and efficiency. The data used was sourced from public medical image repositories such as The Cancer Imaging Archive (TCIA) and Medical Image Analysis datasets, covering various diseases, including brain tumors, lung cancer, and kidney lesions. The research process involves data collection, data preprocessing, dimensionality reduction using Principal Component Analysis (PCA), applying the K-NN algorithm with Euclidean, Minkowski, and Cosine distance metrics, and performance evaluation using accuracy, precision, recall, and F1-score. Experimental results demonstrate that K=5with the Euclidean distance metric provides the best performance, achieving an accuracy of 90%. Additionally, PCA effectively reduces computational time by 30% without significantly compromising accuracy. This study proves that K-NN is an effective method for medical image classification. However, further research is needed to integrate K-NN with deep learning models to enhance performance and feature extraction capabilities.

Open-pit mining system mining is greatly influenced by surface runoff, rainwater and groundwater. This surface water runoff is highly dependent on rainfall catchment areas, climate, and land use. Handling surface water runoff entering the mining area by creating water channels in the form of open channels and closed channels. One of the mining methods that is generally carried out in Indonesia is the open-pit mining method, which is widely found in East Kalimantan. Large basins will be created as a result of this mining technique, which could eventually serve as a reservoir for water from both surface runoff and groundwater. Therefore, an analysis of the runoff water output in the sump is required, sump capacity and appropriate pumping ratio so that mining activities can continue. The results of the study obtained the runoff discharge value in the sump was 4,071.37 m3/day, the sump capacity was 207,474.07 m3, the water balance in the sump with a total runoff discharge of 5,871.37 m3/day, and the existing volume of water in the sump was 24,771 m3. evaporation of 4.36 m3/day, infiltration of 91.36 m3/day, and pump discharge of 8,229.27 m3/day. A pumping ratio of 0.71 was obtained.

Wearing Course Lataston (HRS-WC) is a type of flexible pavement with durable and good durability and flexibility. The constituent materials of HRS-WC asphalt consist of aggregate, asphalt, and filler. Bentonite powder is an active chemical filler material with superior swelling ability, ion exchange properties, and large surface area. It quickly absorbs water to form a thick suspension. This research aims to determine and determine the Optimum Asphalt Content (OAC), optimum filler content, comparison of the percentage value of increase or decrease in Marshall test parameters, and the effect of adding bentonite powder filler to HRS-WC Asphalt on asphalt performance according to the General Specifications for Bina Marga Year 2018 Revision 2. Based on the research results on Marshall characteristics, the KAO value was obtained at 7.5%, and the optimum filler content value was 1.90%. The addition of bentonite filler shows changes in the characteristics of HRS-WC asphalt, namely an increase in stability, Marshall Quotient, and VFA, as well as a decrease in flow, VIM, and VMA. So, the effect of adding bentonite filler to HRS-WC asphalt can increase density, reduce the number of voids, fill voids between aggregates, and be able to bind asphalt to the asphalt mixture. However, the excessive addition of bentonite powder as a filler can reduce the flow value and make the asphalt mixture harder and stiffer.

In Indonesia, restorative justice has begun to receive serious attention, as evidenced by the issuance of several regulations to support its implementation. One of these is the Juvenile Criminal Justice System Law, which incorporates the spirit of restorative justice into efforts to resolve cases involving children through the Diversion mechanism. However, despite the existence of supporting regulations, the implementation of restorative justice in Indonesia still faces various challenges. The purpose of this article is to examine the effectiveness of fulfilling restorative justice in Indonesia. The research results indicate that there are still several shortcomings in the enforcement of restorative justice. Additionally, there is a need for an institution capable of overseeing the implementation of non-litigation processes. The Witness and Victim Protection Agency is considered to have a strong position to act as a supervisor for restorative justice due to its alignment with its duties and functions.

The application of diversion in the juvenile criminal justice system aims to prevent children from undergoing formal legal proceedings that could negatively impact their development. This study analyzes the implementation of diversion in Decision Number 5/Pen.Div/2023/PN Kot Jo and Number 18/Pid.Sus-Anak/2023/PN Kot, involving a 15-year-old minor as the perpetrator of a minor offense. The study highlights the judge's considerations in determining diversion, including the child's age, the type of offense, and the offender's social background. Furthermore, this research examines how the principles of restorative justice are applied through diversion deliberations involving the offender, the victim, their families, and other relevant parties. The findings indicate that diversion in this case successfully reached a voluntary agreement, requiring the offender to return the item and compensate the victim. This agreement not only aims to prevent the negative impact of formal judicial proceedings but also provides an opportunity for the child to rehabilitate and reintegrate into society. These findings emphasize that when implemented effectively, diversion mechanisms can serve as an efficient solution for resolving juvenile delinquency cases without resorting to litigation.

Through this outreach about affiliate make up, it is hoped that the village community, especially women, will understand and be interested in doing affiliate work, especially in the field of make up. The results of this evaluation can be seen from the enthusiasm of the socialization participants who were excited about the material presented and some of them even wanted to try becoming affiliates.

A witness is a person who can provide information for the purposes of investigation, prosecution and justice regarding a criminal case that he himself heard, saw for himself and experienced for himself. The rules regarding the procedures for how a person can be presented as a defendant and then whether he will then be sentenced or not are regulated in a series of writings called the Criminal Procedure Law. In handing down a criminal decision, according to article 183 of the Criminal Procedure Code, a judge may not impose a crime on someone unless there are at least two pieces of evidence. One of the pieces of evidence that can be used by a judge is witness testimony. Children can be witnesses in a criminal trial. However, the validity of children's testimony is often still in doubt and further investigation is needed regarding the validity of children as witnesses in court. In Indonesia itself, the definition of child is regulated in various statutory regulations, including Law Number 23 of 2002 concerning Child Protection. A child is defined as someone who is not yet 18 (eighteen) years old, including children who are still in the womb. This article will explain more specifically the involvement of children as children in conflict with the law in the case of children who are witnesses to criminal acts, the position of children as witnesses in criminal trials, and the strength of the evidence of child witnesses' statements in criminal trials.
