ANALISIS POLA PENJUALAN ALAT KESEHATAN DENGAN ALGORITMA APRIORI PADA PT. DIAN FAJAR CAHAYA GEMILANG

badrul — 2025-09-30

PT. Dian Fajar Cahaya Gemilang is a company engaged in the sale of medical equipment. To improve the quality of service to consumers, the company is required to be able to overcome problems that often arise, including changes in order requests for certain products so that the company cannot provide product stock quickly and accurately. Lack of stock in a company will have a very negative impact on the success and smoothness of sales and purchase transactions. This can be caused by customer sales patterns that are always changing and cannot be predicted. This study implements data mining using the apriori algorithm stage to find valuable information in the form of purchasing patterns by customers by utilizing the large amount of sales transaction data so that the company can prepare stock quickly and accurately to prevent accumulation and lack of product storage that will later result in losses

Putri Anengsi Manurung Sabar Manurung — 2025-09-30

Digestive disorders in children are a serios health issue globally, with diarrhea being a leading cause of mortality among toddlers. In Batam City, the hitgh incidence of acute diarrhea and other digestive disorders in children underscores the urgency for better management. Contributing factors include immature immune systems, unhealthy eating patterns, poor sanitation, low parental understanding of Clean and Healthy Living Behavior, and limited access to medical information and facilities. This problem is futher exacerbated by overlapping symptoms of digestive disorders, making early diagnosis difficult. To address these challenges, this research aims to design and build a web-based expert system application capable of detecting digestive disorders in children. The system implements a Rule-Based Reasing method with a Forward Chaining algorithm, which logically matches user-inputted symptoms against rules in tis knowledge base to generate a rapid initial diagnosis. This application focuses on three main indicators of degetive disorders : Diarrhea, Constipation, and GERD, for children aged 5 months to 12 years. Thus, this expert system is expected to be an interactive tool that enhances parental understanding, facititates early diagnosis of digestive disorders in children, and serves ad a reference for healthcare professionals and the development of health information systems.

PENGEMBANGAN APLIKASI GAME IQRO’ SEBAGAI MEDIA EDUKASI PADA ANAK MENGGUNAKAN CONSTRUCT 2

Marnini — 2025-09-30

Learning to read the Qur’an is a fundamental component of early Islamic education, with the Iqro’ method being one of the most widely used approaches in Indonesia. However, traditional implementations often lack interactivity and engagement, which can reduce their appeal to young learners. In response to this challenge and the increasing digital exposure among children, this study aims to develop an educational game application using Construct 2 as a supplementary medium for teaching Iqro’ reading skills to first-grade students at SD IT Al-Jauharotunnaqiyah Ciajeng. The application presents material from Iqro’ Volume 1 in an interactive format, incorporating audio pronunciation, multiple-choice quizzes, writing simulations, and
immediate visual and auditory feedback. The implementation results indicate that the application fulfills both functional and non-functional requirements. Furthermore, black-box testing confirms that all features perform as intended. This application is considered a suitable and
engaging tool to support early Qur’anic literacy and has the potential to redirect children’s screen time toward educational and spiritually enriching activities.

GAME EDUKASI PENYELAMATAN BUMI DARI SAMPAH BERBASIS CONSTRUCT 2 SEBAGAI MEDIA PEMBELAJARAN

Siti Nurhalizah — 2025-09-30

The issue of waste accumulation has become a critical environmental concern that requires early educational intervention. Conventional waste education methods in elementary schools are often ineffective in fostering students' awareness and behavioral change. This study aims to design and develop an interactive educational game using Construct 2 and the Multimedia Development Life Cycle (MDLC) framework to enhance elementary students’ understanding of waste types, including organic, inorganic, and hazardous (B3) waste. The game, titled "Saving the Earth from Waste", adopts an educational adventure genre, integrating storyline, challenges, and reward systems to provide an engaging and meaningful learning experience. Validation results from teachers and parents indicated positive responses regarding the game’s interface, navigation, and educational content. The game is distributed in .apk format for easy access and installation and is considered suitable as a learning media for environmental education at the elementary level. The main contribution of this research is the provision of an effective, interactive, and contextual adventure-based educational game to support environmental education for young learners

SISTEM PENDUKUNG KEPUTUSAN PEMILIHAN SISWA TERBAIK DENGAN METODE PIPRECIA-MARCOS (STUDI KASUS: SMK TI GLOBAL SINGARAJA)

Marselinus Harson Rewo — 2025-09-30

The selection process for outstanding students at SMK TI Bali Global Singaraja faces objectivity challenges, particularly when assessing candidates with seemingly equal qualifications. This study aims to mitigate subjectivity and enhance transparency by designing and implementing a web-based Decision Support System (DSS). The system was developed using the Software Development Life Cycle (SDLC) framework and integrates a hybrid Multi-Criteria Decision-Making (MCDM) model. The Pivot Pair-wise Relative Criteria Importance Assessment (PIPRECIA) method was applied to determine the weights of seven evaluation criteria, while the Measurement of Alternatives and Ranking according to Compromise Solution (MARCOS) method was used to rank student candidates. The results show that the DSS was successfully implemented, as validated by black-box testing with a 100% success rate. Furthermore, a usability evaluation using the System Usability Scale (SUS) yielded an average score of 75, indicating good user acceptance. This research concludes that the integrated PIPRECIA-MARCOS model provides a structured and accountable framework for decision-making. The novelty of this study lies in the application of this specific hybrid method to the student selection process, offering a robust solution that minimizes bias and increases the integrity of the evaluation
