Abstract

The development of a portable ladder for pepper harvesting in Sanatap Village, Sajingan Besar Sub-district aims to improve farmers' ergonomics, safety, and productivity. Using the Quality Function Rapid Entire Body Assessment (REBA) dan Deployment (QFD) methods, this study identified farmers' key needs such as ease of operation, lightweight materials, and ease of storage. The designed ladder is foldable, has wheels, and is made of strong yet lightweight galvanised iron, and has additional safety features. The results of the analysis showed a significant improvement in the farmers' working posture and a reduction in the risk of injury, from moderate risk (REBA score 4-7) to low risk (REBA score 2-3). This shows that the ladder can reduce the risk of injury to pepper farmers. In addition, this portable ladder is expected to not only improve the efficiency and safety of pepper farmers, but also open new business opportunities that contribute positively to the local economy. The implementation of this tool is expected to improve the welfare of farmers in Sajingan Besar Sub-district and provide practical solutions that are profitable and sustainable.

Abstract

Predictive maintenance involves the early detection of potential machine failures and subsequent maintenance to prevent such failures. Machine learning is a pertinent statistical method for predictive maintenance, enabling the early detection of machine failures and the implementation of preventive measures through a model. The development of the machine learning model commences with data collection from the machine, encompassing vibration, acceleration, machine temperature, and machine sound, facilitated by a microcontroller equipped with sensors. Subsequently, the data undergoes cleaning, including removing outliers or missing values and standardization. Data is partitioned into 70% allocated for training and 30% for testing. After determining hyperparameters and their values through hyperparameter tuning, the training data is utilized to train machine learning models, such as K-nearest neighbor, decision tree, and random forest models. Post-training, the models are evaluated using the remaining test data, employing performance metrics such as accuracy, precision, recall, and F1-score. The random forest model excels due to its utilization of a substantial number of trees for predictions and the full exploitation of the variables which F1-score is 91.22%. The best-performing model is subsequently deployed into a monitoring system, providing real-time machine condition predictions. The deployment results validate the accurate prediction of machine failures.
