Abstract

This study aims to analyze the effectiveness and efficiency of applying AGV in the production system at the PT. Adhikara Wiyasa Gani. AGV is implemented as a means of transporting materials from the warehouse to the production line, as well as returning finished goods to the warehouse. The research method used was data collection through field observations, interviews with workers, and analysis of production data before and after using AGV. The research results show that the use of AGV can increase the effectiveness and efficiency of the production system. The time required for material delivery from the warehouse to the production line and the return of finished goods to the warehouse can be minimized, thereby speeding up production time. In addition, AGV can also reduce production costs by reducing labor costs and minimizing the risk of human error in shipping goods. In conclusion, the application of AGV can have a positive impact on the production system at the PT. Adhikara Wiyasa Gani. However, further research can be conducted to deepen the effectiveness and efficiency of AGV implementation in production systems in general.

Abstract

This article focuses on the application of deep learning methods for failure prediction. Failure prediction plays a crucial role in various industries to prevent unexpected equipment failures, minimize downtime, and improve maintenance strategies. Deep learning techniques, known for their ability to capture complex patterns and dependencies in data, are explored in this study. The research employs Multi-Layer Perceptron as deep learning architectures. This model is trained on AI4I 2020 Predictive Maintenance data to develop accurate failure prediction models. Data preprocessing involves cleaning, feature engineering, and normalization to ensure the quality and suitability of the data for deep learning models. The dataset is split into training and testing sets for model development and evaluation. Performance evaluation metrics such as accuracy, ROC, and AUC are utilized to assess the models' effectiveness in predicting failures. The experimental results demonstrate the effectiveness of deep learning methods in failure prediction. The models showcase high accuracy and outperform SVM approaches, particularly in capturing intricate patterns and temporal dependencies within the data. The utilization of Multi-Layer Perceptron architecture further enhances the models' ability to capture long-term dependencies. However, challenges such as the availability of diverse and high-quality data, the selection of appropriate architecture and hyperparameters, and the interpretability of deep learning models remain significant considerations. Interpretability remains a challenge due to the inherent complexity and black-box nature of deep learning models. In conclusion, deep learning method offer significant potential for accurate failure prediction. Their ability to capture complex patterns and temporal dependencies makes them well-suited for analyzing operational and sensor data. Future research should focus on addressing challenges related to data quality, interpretability, and model optimization to further enhance the application of deep learning in failure prediction.

Abstract

Today in Indonesia, intercity railway service has become an essential part of human mobility and can carry more than 298 million passengers in 2022. It is a reliable service since it can carry many passengers and is a form of time-efficient mode of transport. More and more people are using this service including disabled passengers. They are using the railway to travel between the cities. The railway industry has changed a lot in recent years. If we look at the 90s and before, traveling by train was almost entirely used by non-disabled people and very few of the passengers are people with disabilities. It has now changed while some disabled passengers used the rail, and it created some issues for the industry. This service for disabled passengers is a part of Equality, Diversity, and Inclusion (EDI) and the Author found a mismatch between what the disabled passenger wanted and what the industry responded to. This research will try to understand what is happening in the Indonesian railway industry, compare it with the same issue in another country like the United Kingdom (UK), and what or how to get the ideal design and service for intercity onboard service for disabled passengers. This research uses the triangulation ergonomic principle which consists of measurement, observation, and consultation to combine a literature study and interviews with representatives of 4 stakeholders in the Indonesian railway: 1) A regular user of disabled passenger; 2) Executive Director of one of the Indonesian disability passengers Organization; 3) Traffic coordinator of the Directorate General of Railway (DGR) in the Indonesian Ministry of Transport; 4) A Vice President of the Passenger Division from PT. Kereta Api Indonesia (Persero)/KAI, an intercity railway operator. This interview is then combined with the data from the literature study then analyzed with several methods like Quality Function Deployment (QFD) to get the ideal coach design, Communication-Persuasion Matrix theory to address the communication gap between the parties and make an ideal roadmap solution with phasing approach.
