Analysis of Tool Failure in Stainless Steel Pipe Notching Using Bi-Metal Hole Saw under Manual Operation Norman Iskandar Sulardjaka Bernadus Endra Tri Rahardjo Volume 5, Issue 5, Pages 1-8, May 2026 The notching process of stainless steel pipes is widely applied in fabrication industries, particularly for structural joint preparation. However, machining stainless steel presents inherent challenges due to its low thermal conductivity, high toughness, and work hardening characteristics. This study investigates tool failure in a bi-metal hole saw used under manual machining conditions base... Read More Article DOI: doi.org/10.47001/ICJES/2026.505001
CFD-DPM Based Prediction of Erosion Rate in Elbow Pipe under Seawater Flow Conditions Muchammad Budi Setiyana Galang Hardhian Prasetyo Volume 5, Issue 5, Pages 9-17, May 2026 Erosion due to the interaction of solid particles in fluid flow is one of the main causes of material degradation in piping systems, especially at the elbow sections where the flow direction changes. This phenomenon can reduce the reliability and service life of the pipe due to particle impacts concentrated in certain areas. This study aims to analyze the influence of variations in particle s...

Occupational Noise Intensity Analysis of Grinding Operations and Risk Control Evaluation Using the PDCA Method in a Steel Fabrication Industry Norman Iskandar Nurul Aulia Sulardjaka Volume 5, Issue 5, Pages 25-31, May 2026 Occupational noise is one of the dominant physical hazards in manufacturing industries, particularly in grinding operations involving high-speed rotating machinery. Excessive noise exposure may cause hearing impairment, decreased concentration, communication difficulties, and reduced productivity. This study aims to analyze the noise intensity generated during grinding activities under idle a... Read More Article DOI: doi.org/10.47001/ICJES/2026.505004
Natural Language Processing for Guest Experience and Sentiment Analysis in Hospitality C Lakshmanna N Renuka Chowdary Volume 5, Issue 5, Pages 32-39, May 2026 The hospitality industry increasingly relies on customer feedback to evaluate service quality and improve guest satisfaction. Hotel reviews contain valuable unstructured textual data that reflects customer opinions, emotions, expectations, and overall experiences. However, manual analysis of large volumes of reviews is time-consuming, inconsistent, and susceptible to human bias. To address t... Read More Article DOI: doi.org/10.47001/ICJES/2026.505005
