The preparation of an asset inventory is taken into account the aspects of asset management and risk management. The measurement results with SEM obtained APC values and values &lt; 0.05 and AVIF &lt; 5 so that the relationship between the criteria for asset management and risk management has a significant effect on the design of asset information systems. Measurement of risk management obtained 4 critical risks that affect the design of asset information systems. One of the asset information systems that meet the criteria of being integrated, easy to manage, and easy to update the data is a QR code-based check sheet. Its use in a small scope is easier to implement than using a database system.</p> Yudha Adi Kusuma, Aan Zainal Muttaqin Copyright (c) 2022 Jurnal Sistem Teknik Industri https://creativecommons.org/licenses/by-nc-sa/4.0 https://talenta.usu.ac.id/jsti/article/view/6909 Fri, 29 Jul 2022 00:00:00 +0700 The PDCA Approach with Seven Quality Tools for Quality Improvement Men’s Formal Jackets in Indonesia Garment Industry https://talenta.usu.ac.id/jsti/article/view/7711 <p>Garment production with men's jacket products still finds products with poor quality and a high percentage of defects. The method used in this study is the PDCA approach with seven quality tools. The purpose of this study is to determine the cause of defects, provide solutions to repair these problems by reducing product defects, and reduce the percentage of dominant defects in the Finishing section. This study found that the factors causing the damage were human, machine, method, material, and environmental factors. Meanwhile, improvement efforts are contained in the Action stage, namely 5W+1H. The results of these improvements have an impact on the reduction of finishing defects from 17.8% to 11.8% which means a decrease in defects by 33.7% every month in the finishing section. The implications of this research can be used as a reference to reduce similar problems in the garment industry process. The combination of the PDCA approach and seven repair tools results in a defect percentage control system using a control chart so that defects will be controlled and corrective actions will be taken quickly.</p> Didin Sjarifudin, Hibarkah Kurnia Copyright (c) 2022 Jurnal Sistem Teknik Industri https://creativecommons.org/licenses/by-nc-sa/4.0 https://talenta.usu.ac.id/jsti/article/view/7711 Fri, 29 Jul 2022 00:00:00 +0700 Integration of the HEART and SHERPA Approach to Evaluating Human Errors in the Refinery Salt Production https://talenta.usu.ac.id/jsti/article/view/7755 <p>Human error can be prevented by measuring human reliability through the Human Reliability Assessment approach. PT A is a national scale salt producer that produces salt. The quality division identifies human error problems made by operators in the salt refining process. This study aims to identify, calculate probability values, and provide recommendations for improvement to reduce human error in salt refining production operators. HEART and SHERPA are research approaches used because they are considered the most suitable for this study. The results showed that the most visible human error for the error mode category was C2, incomplete checking, and 42 error modes because the operator infrequently did a complete check. The process with the highest Human Error Probability value is the drying process 1, with a value of 7.49. In contrast, the process with the most minor Human Error Probability value score of 0.085 is the bagging process 2. Human error prevention efforts are carried out for each process based on the highest score on the Human Error Probability Index, including Personal Protective Equipment, Standard Operating Procedures, and training to improve operator skills.</p> Putri Rammadaniya, Nina Mahbubah Copyright (c) 2022 Jurnal Sistem Teknik Industri https://creativecommons.org/licenses/by-nc-sa/4.0 https://talenta.usu.ac.id/jsti/article/view/7755 Fri, 29 Jul 2022 00:00:00 +0700 The Measurement Of Employee Performance With A Human Resource Scorecard Methods: A Study Case in PDAM MEDAN https://talenta.usu.ac.id/jsti/article/view/8566 <p class="JAbstractTextENG" style="line-height: normal;">The success of an organization or company in carrying out tasks with the aim of realizing the company's vision, mission, and goals can be seen from the performance of its human resources. So far, PDAM Tirtanadi's employee performance measurement is still focused on the financial aspect and based on a preliminary questionnaire, employee performance is in the poor category. So that this research has the aim of designing indicators and measuring employee performance with the Human Resource Scorecard (HRSc) approach. HRSc is a performance measurement based on 4 perspectives, namely finance, employees, internal business processes, and growth. From the results of data collection and processing, 16 indicators and 18 key performance indicators (KPI) were obtained, so that by using the Likert scale method and questionnaire in each perspective, the measurement value was 3.385 with a less category.</p> KHAIRUN NISSA SIREGAR NISSA, Sukaria Sinulingga, Meilita Tryana Sembiring Copyright (c) 2022 Jurnal Sistem Teknik Industri https://creativecommons.org/licenses/by-nc-sa/4.0 https://talenta.usu.ac.id/jsti/article/view/8566 Fri, 29 Jul 2022 00:00:00 +0700 Flood Disaster Relief Operation: A Systematic Literature Review https://talenta.usu.ac.id/jsti/article/view/8378 <p>A flood is natural disaster that often occurs in many regions. Flood has a significant impact on the nature conditions, local communities, and regional economic losses. The flood can happen due to a damaged environmental system; therefore, it needs deeper study and extra effort to prevent it. Thus, an appropriate and right Disaster Relief Operation (DRO) is needed in responding to flood disaster. In this research, 50 articles categorized in "flood disaster relief operation" published in the range 2012 to 2022 have been reviewed. This review is conducted by using the Systematic Literature Review (SLR) method. This study aims to explore and analyze flood DRO. The findings reveal that the flood DRO still has several weaknesses in the current system that should be improved: the lack of an integrated information system, not enough collaboration of the stakeholders, the lateness of information exchange, and unplanned relief operations through the preparation. For further research, it is recommended to implement the proposed system in the relief operations execution.</p> Febrina, Johan K. Runtuk, Anastasia L. Maukar, Erri W.

One of the popular research is using analytical method. The purpose of this study was to determine the relationship between work activity behavior, government and community regulations and social distancing as a mediator in preventing an increase in Covid-19 cases in West Java. This research method uses path analysis model. Social distancing variables directly have a positive and significant impact on preventing positive cases of Covid-19, meaning that with social distancing the spread of the Covid-19 virus can be reduced. The effect of social distancing on the prevention of positive cases of Covid-19 is 87% and the remaining 13% is due to the influence of other factors. Based on the four variables used as predictors of the prevention of Covid-19 cases, the social distance variable is the strongest variable that affects the prevention of positive cases of Covid-19 compared to the other three variables. Social distancing is very important to reduce the spread of Covid-19 cases. The implication of this research shows that awareness of people's behavior by keeping a distance is very important to prevent the Covid-19 virus.</p> Welly Atikno, Hibarkah Kurnia, Indra Setiawan, Bambang Setiawan, Bayu Hari Nugroho, Muhammad Wahid Copyright (c) 2022 Jurnal Sistem Teknik Industri https://creativecommons.org/licenses/by-nc-sa/4.0 https://talenta.usu.ac.id/jsti/article/view/8499 Fri, 29 Jul 2022 00:00:00 +0700 Risk Mitigation Design in the Production Process of Packaged Fruit Juice Drinks Using a Fuzzy Based House of Risk (HOR) Approach https://talenta.usu.ac.id/jsti/article/view/8498 <p>Agro-industry is a sector that has quite diverse development potential, especially in the field of processing. One of them is processing fruit into fruit juice drinks. Nozy Juice is classified as an advanced MSME, but its competitive level is still lower than other agro-industry. This is because almost all of Nozy Juice's production activities are still done manually, giving rise to various risks that have an impact on decreasing the company's productivity level. To reduce this risk, a fuzzy-based House of Risk (HOR) approach is used which aims to identify the most critical risk agents. Then the risk mitigation design is carried out as an action plan. The essential risk of the 15 risk agents was a human error with an Aggregate Risk Potential (ARP) percentage of 24.275%. Furthermore, a risk mitigation design is carried out for 10 risk events. This is expected to minimize risks in the production process of packaged fruit juice drinks at Nozy Juice.</p> Copyright (c) 2022 Jurnal Sistem Teknik Industri https://creativecommons.org/licenses/by-nc-sa/4.0 https://talenta.usu.ac.id/jsti/article/view/8498 Fri, 29 Jul 2022 00:00:00 +0700 Inventory Optimization Model Design with Machine Learning Approach in Feed Mill Company https://talenta.usu.ac.id/jsti/article/view/8637 <p>This article aims to address the impacts that companies can have with the application of machine learning to carry out their demand forecasts, knowing that a more accurate demand forecast improves the performance of companies, making them more competitive.

The horse's hooves are repeatedly subjected to loadings during walking, trotting, running and jumping. In this research, we introduce a newly developed horseshoes made of polymeric composite materials. The horseshoes are placed inside the leather boot; it is a specially designed for horse. The process of making horseshoes and horse boots were discussed and the responses of the horse shoes as well as horses were analyzed. The horses were subjected to a series of testing, e.g., walking, trotting, and running. The result of the tests indicate that horseshoes and horse boots are quite strong, light, and safe to be used on horses. The response of horses shows that the horseshoe and boots are quite comfortable for them. This can be seen because there are no significant behavioral changes of the horse before and after wearing the boot. After being used to, it was shown that there is no damage or crack of the horseshoe. Therefore, it can be concluded that the composite horseshoe is safe and good to be used as horseshoe material.</p> </div> </div> </div> Bustami Syam, Maraghi Muttaqin, Julius Tantono, Eddo Eddo, Febri Sandry Copyright (c) 2022 Jurnal Sistem Teknik Industri https://creativecommons.org/licenses/by-nc-sa/4.0 https://talenta.usu.ac.id/jsti/article/view/8664 Fri, 29 Jul 2022 00:00:00 +0700
