EXPERT SYSTEM DIAGNOSIS PENYAKIT JANTUNG MENGGUNAKAN METODE RULE-BASED REASONING BERBASIS ANDROID
Get PDFCardiovascular disease remains one of the leading causes of mortality worldwide, emphasizing the urgency of early detection and preventive efforts. This study presents the design and development of an expert system application for the diagnosis of heart disease using a Rule-Based Reasoning method, implemented on an Android platform. The application enables users to input symptoms and severity levels through an intuitive interface. These inputs are then matched against a knowledge base consisting of expert-defined rules to generate potential diagnostic results. The system is expected to support both individuals and healthcare workers by providing preliminary insights before further medical examination. The use of mobile technology ensures wider accessibility, real-time interaction, and ease of use. Testing results demonstrate that the application performs with satisfactory accuracy in diagnosing based on symptom patterns. Future enhancements may include integration with Certainty Factor methods or machine learning to improve diagnostic precision
ANALISIS PERBAIKAN KUALITAS PROSES PEMBUATAN TAHU PADA UKM TAHU JK
Get PDFJK Tofu SME still faces obstacles in meeting market demand due to wasteful activities in the production process, such as excessive soybean soaking time and inconsistent and unmeasured yeast addition. This study aims to identify factors affecting tofu production process quality and process requirement standards. The methods used are quantitative approaches through DPMO calculations, Value Stream Mapping, and QFD. The results show that the production process still has defects such as dirty, smelly, and soft tofu. Current Value Stream Mapping analysis indicates low efficiency with a PCE of 51.67% and non-value-added time (NVA and NNVA) of 290 minutes. After improvements through Future State Mapping, the PCE increased to 71.26% and the total process time decreased to 435 minutes. The average DPMO of 33,333.33 with a sigma level of 1.933 indicates that quality is still far from Six Sigma standards. Through QFD Levels 1–3, consumer needs are translated into technical specifications, product characteristics, and production process requirements. Specifications such as ingredient composition and cooking processes influence product quality, while integration across QFD levels strengthens quality control. QFD provides strategic and operational guidance for continuous product quality improvement. This study shows that analyzing the causes of waste can affect product quality and that it is necessary to determine process requirement standards

FAKTOR–FAKTOR YANG MEMPENGARUHI KEPUTUSAN PEMBELIAN PELEMBAB WAJAH GARNIER DI KOTA BATAM
Get PDFThis study aims to identify and analyze the extent to which Brand Ambassador, brand image, and product quality influence consumer purchasing decisions for Garnier facial moisturizer products in Batam City. The increasingly competitive beauty industry demands companies to implement effective marketing strategies, including the use of public figures, brand identity reinforcement, and the provision of high-quality products. A quantitative approach with a survey method was used in this research.

The results indicate that brand image and product quality have a significant impact on purchasing decisions, while Brand Ambassador does not show a significant effect.

THE ROLE of PRODUCT CHARACTERISTICS and PRICE DISCOUNTS in ENHANCING CUSTOMER SATISFACTION and LOYALTY
Get PDFThis study aims to examine the role of product characteristics and price discounts in building customer satisfaction and loyalty. The study is motivated by the growing competition among café businesses, where customer retention and satisfaction are crucial for business sustainability. This research explores whether product features and price discounts can effectively shape customer loyalty, either directly or through the mediating role of customer satisfaction. Using a quantitative approach, data were collected through purposive sampling involving 114 respondent who had previously visited MoMoo Café, located in a popular culinary tourism area. The analysis was conducted using Partial Least Squares Structural Equation Modeling (PLS-SEM) to test the proposed hypotheses. The results show that price discounts do not have a direct and significant effect on customer loyalty. However, discounts were found to significantly influence customer satisfaction, which in turn significantly affects customer loyalty. This indicates that although discounts do not directly create loyal customers, they enhance satisfaction through the perception of value received, which subsequently drives loyalty. In contrast, product characteristics were found to have no significant influence, either directly on loyalty or on customer satisfaction. These findings highlight the importance of customer satisfaction as a strategic mediator in the formation of loyalty. Therefore, businesses operating in tourist areas should not rely solely on price promotions but should focus on creating a satisfying customer experience. Enhancing service quality, ambiance, and emotional engagement with the brand can result in more sustainable loyalty than price-based incentives alone. This study contributes to the consumer behavior literature in the tourism context by emphasizing the indirect role of price discounts and the central position of satisfaction in building long-term customer relationships
