Abstract

Time series forecasting is a method used to determine what might happen in the future based on information obtained in the past. One method used in time series forecasting is a Holt-Winters exponential smoothing method. This method can be used for time series data with trend and seasonality components. This method is based on three smoothing equations: overall smoothing, trend, and seasonal components. Holt-Winters exponential smoothing method consists of multiplicative and additive seasonality models. The method of this research is literature study by collecting and studying references that are relevant to the idea of this research, and then applying the Holt-Winters exponential smoothing method into data. The results of this research show that the multiplicative seasonality model of Holt-Winters exponential smoothing method can be used if data represent an increase in long-term and seasonal fluctuations which is the increasingly bigger with the increasing of observation time periods. These patterns identify the non-stationary of mean and variance. While, the additive seasonality model can be used if data show an increase in long-term and seasonal fluctuations that are relatively constant with the increasing of observation time. Time series forecasting is a method used to determine what might happen in the future based on information obtained in the past.

Abstract

A technology is essentially created to make human life easier and more comfortable. There is almost no area of ​​human life that is free from its use, either directly or indirectly. This is also a result of the very rapid development of technology. Technology was created to facilitate every human activity. Born from human thoughts that try to facilitate their activities which are then applied in everyday life, one of which is in the teaching and learning process in schools. Thus in the learning process, technology can be used as a learning resource. Today, technology products have become a daily necessity in carrying out life activities. The use of cellphones and internet is not something strange or new anymore. Mobile is an electronic telecommunication device which has basic capabilities conventionally which is easy to carry and does not need to be connected to a telephone network using a cable. Mobile has a function to receive calls or SMS (short messages), cellphones can also function as a means of tracing, recording all activities, as a means of information and can even be used to explore the world of the internet depending on the features of the cellphone.

Abstract

ABSTRAK The legal literacy and numeracy literacy skills of students at MI Nurul Huda Jelu still need to be improved. One of the contributing factors is the inability of teachers to integrate these optimally. This study aims to implement strengthening training in order to support the implementation of the Merdeka Curriculum at MI Nurul Huda Jelu. This training is aimed at improving teachers' abilities in integrating legal literacy and numeracy in the classroom learning process. Data were collected through interviews, observations, and documentation. The evaluation of this training is in the form of a test sheet. The results of the question training show that the abilities of students, with an average score of students in the legal literacy question training being 93, while in the numeracy literacy work the average score of students was 56. Students and teachers who take part in this training are expected to be able to compile and implement more contextual and relevant learning according to the needs of students. The suggestion from this community service activity is that teachers are consistently expected to apply and integrate learning with the legal literacy system and numeracy literacy in the learning process.

Abstract

Applying ergonomic principles in work tool design for manufacturing industries is a crucial factor in improving productivity while maintaining worker health. This research aims to analyze the effectiveness of adaptive work tool design models based on cognitive and physiological ergonomic principles, identify interaction patterns between workstation design and operational performance, and develop a conceptual framework for integrating ergonomic principles into production cycles. The research method adopts a cognitive-physiological approach with qualitative analysis of human-machine interactions, biomechanical simulations using digital human modeling, and muscle load measurements through electromyography. Implementation was conducted using a participatory ergonomics approach and IMU sensor-based real-time monitoring systems. Results show that using materials with controlled deformation capabilities (15-20%) in work tools reduces muscle work by up to 27%, while adaptive automation system integration improves assembly accuracy by 18%. Workstations with ergonomic adjustments increase assembly speed by an average of 12%, and low-cost ergonomic interventions effectively improve productivity by 11-15% in resource-limited environments. Longitudinal analysis reveals that evidence-based ergonomic investments yield a 230% ROI through increased productivity, reduced injury compensation costs, and decreased employee turnover. IMU-based posture monitoring systems integrated with adaptive feedback loops reduced musculoskeletal disorder incidents by up to 41%. In conclusion, ergonomic optimization based on cognitive-physiological principles creates synergy between production efficiency and worker well-being, making it an essential component in achieving sustainable productivity.
