Service becomes a value addition to the products offered. A product-service system (PSS) is a tangible manifestation of the integration of services and products. However, the integration of products and services must still ensure the quality of PSS. This paper aims to review the development of research related to the quality of PSS where products and services are considered as an integral part of the integration results. Previous research investigations were carried out by collecting journals discussing PSS. The quality of PSS was then discussed, and its mapping to the quality dimension. The mapping shows the research clusters that can be examined for emerging trends in research and potential future research. Those potential future researches are related to the dimension of reliability, durability, serviceability, aesthetic, and perceived quality.","PeriodicalId":178760,"journal":{"name":"Proceedings of the 2022 International Conference on Engineering and Information Technology for Sustainable Industry","volume":"65 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131623359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The six-sigma method is applied to improve quality. The highest defects occurred in the sealing process with four types of defects, they are seal join, seal damage, seal crooked, and perforation. Based on the analysis, the most dominant defects are seal joins and seal damage. The problem is the lack of operator skill to set up the machine, the lack of operators on the production floor, and the operator's lack of understanding of the SOP. The best improvement to be proposed to the company is making a work assessment form and a checklist of work instructions for operators. The improvement could not be implemented due to the pandemic.","PeriodicalId":178760,"journal":{"name":"Proceedings of the 2022 International Conference on Engineering and Information Technology for Sustainable Industry","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114767323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These activities are mainly implemented manually which bring high posture risk for the operators. This research is aimed to analyze ergonomic risk in painting industry by utilizing Ergo-FMEA (Failure Mode and Effect Analysis) methodology. Research stage is commenced by starting with job analysis, identification, ergonomic risk valuation and analysis, and improvement design to minimize risk. Risks are identified based on six risk categories namely horizontal distance, vertical distance, position, movement, environment, and performance. Identification results revealed 14 risks of work posture faced by operators. Activities that produce the highest risk are manual product moving and manual product lifting. These risks often lead to muscle pain, twisted joints, and back injury. The proposed improvements to minimize these risks are wire cart work facility design, workplace layout process costing improvement, and SOP of safe manual product lifting. This improvement proposal is expected to minimize the risk of posture on painting operators.","PeriodicalId":178760,"journal":{"name":"Proceedings of the 2022 International Conference on Engineering and Information Technology for Sustainable Industry","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115162761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nadya","doi":"10.1145/3557738.3557883","DOIUrl":"https://doi.org/10.1145/3557738.3557883","url":null,"abstract":"One of the stages in mining is processing. At the processing stage. minerals are processed to produce products with higher mineral concentrations. This process has by-products called tailings. The Indonesian mining industry as one of the world's nickel producers cannot be separated from this issue. The large nickel production also has an impact on the large tailings production. These tailings are generally just stockpiled without further use. This study aims to provide an understanding of the strength of the material resulting from the addition of tailings to the concrete mixture. Five variations of the material were made by mixing tailings with ratios of 0%, 20%, 40%, 50%, and 60% in the concrete mix. Physical and mechanical properties testing was carried out to obtain the rock strength value from the concrete sample. During this research, the parameters of UCS, Young's Modulus, and Poisson's Ratio were used as indicators of rock strength. Based on the tests that have been carried out, the addition of tailings to the concrete mix generally weakens the strength of the concrete. However, there is a trend of increasing rock strength at a mixture ratio of 60% where the UCS value is 1.324 MPa and Young's modulus is 0.584. Furthermore, porosity and degree of saturation are considered to have a role in these rock strength parameters. This is indicated by the degree of saturation of the 60% ratio, which is 18.8 with an increase in Young's Modulus and UCS. Based on these results, it can be concluded that tailings can be further utilized in concrete mixtures so that their availability in the field can be converted and reduced. Finally, other parameters of the mixing ratio can be performed to complement the weaknesses in this study.","PeriodicalId":178760,"journal":{"name":"Proceedings of the 2022 International Conference on Engineering and Information Technology for Sustainable Industry","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126305191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rahadian","doi":"10.1145/3557738.3557847","DOIUrl":"https://doi.org/10.1145/3557738.3557847","url":null,"abstract":"In 2013, PT X received a request for the construction of 2,109 tower units which would later be rented out by PT Y. Thus, PT X started planning the tower construction in 2014. However, only 242 sites of the projected 856 towers were completed in the first quarter of 2014. This could lead to a potential withdrawal of the tower construction request by PT Y. As a consequence, PT X's management attempted to speed up the tower construction process by procuring mobile towers to serve as temporary replacement towers before conventional towers could be established. Therefore, feasibility study analysis was necessary for the purchase of the mobile towers. The data were collected by distributing questionnaires, conducting interviews, and gathering historical data of the company. Calculations were made based on these data for two alternative decision-making scenarios: without the purchase of mobile towers (alternative A) and with the purchase of mobile towers (alternative B). In addition, the calculations were done using several methods, namely net present value (NPV), internal rate of return (IRR), payback period (PBP), and profitability index (PI). From the two alternatives, alternative B was determined as the best alternative with an NPV of IDR 273 billion, an IRR of 13,81%, a PBP of 14 years and 10 months, and a PI of 1,14. Subsequently, a risk analysis was performed using sensitivity analysis for three variables, namely the possibility of increasing tower construction costs, decreasing revenue from tower rentals, and increasing tower operational costs. Among the three variables, the variable that most influenced NPV and IRR was a decrease in revenue from tower rentals with an NPV of IDR 32 billion and an IRR of 11.78%. Furthermore, Monte Carlo analysis was performed for three risk analyses simultaneously. From 10,000 trials, the probability of NPV < 0 was 1.06% and IRR < WACC was 1.03%, indicating that the chosen alternative (B) has a very small probability of failing. The study's findings led to the conclusion that alternative B would be the best option for PT X. The results of this study can also be a recommendation for other tower providers and further researchers to conduct further studies on the procurement of mobile towers.","PeriodicalId":178760,"journal":{"name":"Proceedings of the 2022 International Conference on Engineering and Information Technology for Sustainable Industry","volume":"255 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124210436","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The production of global palm oil mostly comes from Southeast Asia and South America. However, palm oil production also gives several negative impacts on society and the environment. Palm oil's negative impact has been a significant issue in most palm oil producers in the world, especially in Indonesia, which contributed the most significant portion of the world's palm oil production. Therefore, a sustainable supply chain management model for the palm oil industry needs to be conducted. The supply chain needs to consider social factors and the environment as crucial factors to create sustainability. This paper proposes a framework for a sustainable supply chain (SSC) with the integration of the Internet of Things (IoT) to meet company goals, achieve customer requirements, and also sustainability for the company, societies, and environment. The method for conducting the study is by comprehensive literature review. The most important finding is IoT that present in the study becomes an enabler to give visibility and transparency for the entire SSC as enhancement of technological use might give a significant benefit.","PeriodicalId":178760,"journal":{"name":"Proceedings of the 2022 International Conference on Engineering and Information Technology for Sustainable Industry","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128916624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
