The presence of the internet of thinks (IoT), is able to solve problems related to warehouse security. This study aims to be able to control warehouse security in real time remotely by utilizing SMS notification messages on mobile phones. Applying the prototyping research method, this research on warehouse monitoring systems with ultrasonic sensors based on the Arduino microcontroller is able to produce system security by providing hazard warning messages to warehouse supervisors. So that incidents of theft can be detected in a fast time.</em></p> 2022-05-12T10:24:22+00:00 ##submission.copyrightStatement## Work Accident Risk Analysis Using the HIRARC Method 2022-05-15T00:33:53+00:00 Fajar Muhammad Khudhory Lina Dianati Fathimahhayati Theresia Amelia Pawitra <p><em>CV. Jaya Makmur repairs and sells second-hand heavy equipment spare parts. This workshop has an area of about 400 m<sup>2</sup> with limited working space due to large number of materials like machines, tools and finished products spread around. When doing work activities, it was often found that workers did not wear complete Personal Protective Equipment (PPE). This condition led some minor work accidents ovvur almost everyday. Due to many potential hazards in CV. Jaya Makmur, analysis related to occupational health and safety needed to be done in order to control the potential hazards. This research aims to identify potential hazards, assess risks, and control the risks in CV. Jaya Makmur using HIRARC method. Based on the results of observations and interviews with a workshop owner and three workers, there were 18 potential hazards. There were also 12 low level risks and 22 moderate level risks. There was some risk control that can be done like engineering control, which is installation of barriers between the source of danger and workers. There were also some administrative control like changing work procedures, conducting supervision and warning, providing training to workers on the importance of occupational safety and health in the workplace, as well as making and performing periodic maintenance on work equipment. In addition, the workers needed to use personal protective equipment like work clothes, face shield, safety glasses, gloves, safety helmet, mask, safety shoes, and earmuff while working.</em></p> 2022-05-13T08:00:59+00:00 ##submission.copyrightStatement## Redesign of Production Facilities Layout for Writen Natural Dye Batik 2022-06-10T05:59:41+00:00 Nancy Oktyajati Diyah Dwi Nugraheni Sri Mayasari Sri Purwanti <p><em>Batik is an indigenous Indonesian product that is recognized worldwide. One way to preserve and develop batik culture is increasing the batik business productivity effectively, economically, and safely. Increasing the productivity of the batik industry can be realized by minimizing production costs. Reduction of operational costs can be done by designing the layout of the facility. Redesigning the layout and facilities is closely related to the design of the floor production as an object. Layout planning is a way of managing existing facilities on the production floor so that production can run smoothly. This study, aims to redesign the facilities on the floor production at SME Batik Natural Jarum so that they have a more efficient material flow. Arrangements are made for all work stations: raw material storage, production areas, and finishing areas. The purpose of this facility redesign is make the movement of materials run smoothly and reduced material handling costs. The method used in this research is Systematic Layout Planning (SLP). The results of the proposed layout redesign are a reduction in material handling distances and material handling costs by 8%.</em></p> 2022-05-31T00:00:00+00:00 ##submission.copyrightStatement## Comparison of Forecasting Methods Using Time Series Models 2022-06-10T23:51:32+00:00 Monanda Wandita Rini Nessa Ananda <p><em>Forecasting needs to be done to predict conditions in the future so that they can prepare the required resources. PT XYZ is a manufacturer of veterinary drugs with one of its products being probiotics with a size of 2kg whole research problems being studied. Demand for probiotic products fluctuated so that forecasting was needed to predict the number of products in the future period. This study aims to compare demand forecasting with forecasting methods on the Time Series Forecasting Model and determine the best forecasting method. Forecasting methods used are Moving Average, Weighted Moving Average, Exponential Smoothing, and Trend Linear. Based on the error measurements that have been made, the Trend Linear method gives the Mean Square Error, Root Mean Square Error and Mean Percentage values smaller than other methods. Meanwhile, the error measurement based on the Mean Absolute Deviation and Mean Absolute Percentage Error, the Exponential Smoothing method with α = 0.5 gives a smaller value than other methods. However, in the verification of forecasting based on tracking signals, the results show that the Linear Trend method is more predictive and gives closer to actual results than the Exponential Smoothing method with α = 0.5. Therefore, the best forecasting method chosen is the Linear Trend method. The results of forecasting the demand for 2kg probiotic products for the next period show an increase in demand. The results of this study are expected to provide recommendations for companies to determine policies to prepare to fulfill demand in the coming period.</em></p> 2022-05-31T00:00:00+00:00 ##submission.copyrightStatement##
