Abstract

Narkoba is an abbreviation for narcotics, psychotropics, and other addictive materials. Drugs themselves can be interpreted as artificial substances that affect the behavior, thoughts, feelings, and conditions of the consumer. Drugs or narcotics can also be interpreted as natural, semi-synthetic, or synthetic substances or drugs that can cause decreased consciousness, excitability, and hallucinations. These drugs cause addiction due to excessive use. The reason for using forward chaining is that many different methods and rules for drawing conclusions are very simple, and researchers want to draw conclusions from the truth. To overcome this problem, researchers use the forward chaining method, which allows them to find solutions based on symptom data selected by the user. The system built can provide suggestions in the form of diagnostic results and solutions based on the facts presented.

Abstract

Various problems due to shortages in attendance are still implementing the system manual method so that the teacher feels that it has reduced flexibility in attendance. Following up on the problem, system changes must occur in order to support the attendance program. The system that was built applies some of the technology (internet of things) with a combination of hardware that functions to scan student cards of the Smart Quik Response Card type and web-based software for processing machine data with a MySQL database. The method of choice for software design is to apply bcrypt as password security at login to overcome breaches in attendance data. The results of this study built an automatic attendance system based on a smart quik response card. Based on testing by applying the blackbox method to accurately assess the attendance system that has been built, it gets a compatible score or runs smoothly for each trial feature. After experimenting with the implementation at the research location, it can be concluded that the process of absenteeism that occurs at school aims to make teachers more efficient and facilitate administration in using the application system to become disciplined and timely students.

Abstract

In order for sales transaction data to be useful and useful, data development or data mining methods are needed, especially in the use of the apriori association rule algorithm, in utilizing sales transaction data obtained from items purchased simultaneously by consumers when shopping. The data is used to find out items that are often purchased by consumers to increase their stock and reduce the stocking of goods that are not selling well. The data is also used by the store in arranging the placement of goods according to consumer behavior when shopping. Data retrieval with association rule is done through a mechanism with a minimum support of 0.17 and a minimum confidence of 0.60. The purpose of this study is to determine the results of analyzing transaction data that accumulates in clothing stores into useful information and to find out what items are bought simultaneously by consumers at clothing stores to manage inventory and can make it easier to arrange the placement of goods according to consumer interests based on the value of support and confidence. From the results of this study, items that have a relationship are Women's Tops and Men's Tops with a support value of 27.86% and a confidence value of 68.00%. This information can also be used to find out what items are in great demand and less in demand by consumers in determining what stock procurement should be prioritized in the future.
