Abstract

The Second Gangbrand shoe shop is one that sells second-hand shoes or what you could also call quality and original second-hand shoes that have certain brands at affordable prices that are cheaper than the original price. This research aims to measure the level of customer interest by comparing the C4.5 algorithm method and the Naive Bayes algorithm. The data source was obtained from second gangbrand stores which were taken based on customer interest. So it is necessary to carry out data analysis to classify customer interest data using the C4.5 and Naive Bayes algorithms to compare accuracy and precision which are the benchmarks in this research. Calculations in this research were carried out manually using Microsoft Excel according to the C4.5 and Naive Bayes algorithm calculation models and then evaluated using the Rapidminer 10.3 tool which was used to help determine accurate values. After conducting research testing, the C4.5 algorithm received an accuracy value of 60.00% and a precision of 50.00%, while the Naive Bayes algorithm received an accuracy value of 60% and a precision of 33.33%. So it can be concluded that the two algorithms have the same accurate accuracy value, but in terms of precision value the C4.5 algorithm is superior in determining customer interest recommendations. It is hoped that the results of this research can provide input and information for future researchers.

Abstract

Indonesia is a country that has advantages in the agricultural sector which has the largest plantation and agricultural areas in ASEAN, one of which is oil palm plantations. Indonesia is one of the largest crude palm oil (CPO) business players in the world. More and more palm oil mills and oil palm land are being converted to oil palm cultivation, because oil palm plantations are more beneficial for farmers and palm oil processors. Palm oil plantations are still trying in several ways to maintain stable market demand, one of which is by increasing palm oil production, because palm oil is the main source of other product derivatives. Palm oil production fluctuates every month, but the ups and downs are caused by many factors, namely climate, rainfall, soil fertility, selling prices, and others. Reduced production has a direct impact on the income of farmers and workers in the sector, which in turn can cause economic instability. Actions are needed to ensure the continuity of this industry, one of which is by making predictions. One prediction technique is the Backpropagation artificial neural network. The prediction model can provide very accurate estimates of palm oil production at the provincial level. By analyzing historical data, this research can identify patterns that can help predict future palm oil production. The urgency lies in the strategic role of palm oil in the Indonesian economy.

Abstract

The Beginner Teacher Induction Program is an introductory activity at a particular school/foundation, the training covers all teaching and learning activities and an introduction to the structure of the organization that exists in that institution, both the school and the foundation. The concept of work/method of work of the induction teacher includes 3 actors, namely the novice teacher as the object, the accompanying teacher as the provider of material directions and assignments to the novice teacher, and the Educational Institution as the control/validation of the results of learning/introduction to novice teachers. This research was built by applying a web base with the use of online media. The results of this study are in the form of a web-based application that can be used as an information tool to prepare novice teachers to become professional teachers in carrying out the learning process and as a reference in getting to know organizational schemes in a related agency.

Abstract

E-learning is an important advance in the modern education system. While an Illustration is an art of visual on writing artwork, drawing, painting, photography or another type on an art. Most People want to be an illustrator usually must learning their skill basic with self-taught or learning on art of school. However most people specifically for known illustration and want to learn their skill on art school but constrained with distance or time or another reason with their tools art. Until the most people can not got their skill with fast. By looking at this times with the Design Online Learning Of Education On Illustration At Website, which have contain more information and education about illustration and the illustrator can make easier for other to learning or to hone their skill with complete material which is came from most experience illustrator. The design will become a place of sharing content about illustration, it was built with PHP, and DBMS MySql. This research resulted in an e-learning application using Iconix process.

Abstract

The assessment system at SMK TI Budiagung still relies on conventional methods but has gradually shifted towards AI-based automated assessment. This study aims to analyze the effectiveness of an automated assessment system using the Certainty Factor method in evaluating students objectively and accurately. The research methodology includes interviews with educators and an analysis of the implemented system. The findings indicate that automated assessment enhances efficiency in grading objective answers but faces challenges in evaluating subjective aspects such as creativity and problem-solving skills. Furthermore, the application of the Certainty Factor method allows the system to provide assessments based on calculated certainty levels from available data. The main challenge is ensuring valid and weighted data for more accurate evaluation results. With further development and integration into the learning system, automated assessment is expected to improve academic evaluation quality at SMK TI Budiagung.
