This paper’s study case is in one of the buildings in University at Bandung which uses fiber optic and wireless network for both 2,4GHz and 5GHz frequencies. Existing conditions were tested in site surveys which are high frequency interference of wireless signals, misconfigured channel bands caused frequent disconnections close to two different access points, and there are blank spots causing user’s devices cannot properly connect to network. Wireless network optimization needs to be done to solve its problems. Method used is the Network Development Life Cycle (NDLC) which consists of Analysis, Design, and Simulation Prototyping phases, and performance measurements using Quality of Service (QoS) parameters. Site survey results showed many high interference areas caused by channel misconfiguration in each access point that the same channel can be used for adjacent access points, misplacing wall-mounted access points on ceiling which can interfering both upper floor and lower floor networks. QoS performance measurements to match TIPHON Standardization for throughput is higher than 1kbps, packet loss lower than 3%, and delay lower than 150ms. Recommendation for optimizing network is properly configuring channel band using non-overlapping channel configuration (1-6-11) for all adjacent access points, and there is simulation for replacing wall-mounted access points that placed on the ceiling to a ceiling-mounted type access point. It showed a decreasing interference in the entire network, whether its on the same floor or between upper and lower floor.","PeriodicalId":471454,"journal":{"name":"JRSI : Jurnal Rekayasa Sistem & Industri","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136301003","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 building sector accounts for 31% of global energy consumption. Humans also increasingly recognize the importance of the health aspects, convenience indoor quality, and user safety in the building. This study combines the concepts of green building assessment and green ergonomics to produce a new framework called green ergonomic building. The green ergonomic building is a building condition that not only focuses on energy use, indoor quality but also health, convenience, safety, and improving quality of human life in carrying out their activities in buildings. The development of a green ergonomics building assessment model was developed from literature studies and questionnaires distributed to respondents working in green building certified office buildings. Data processing using the Principal Component Analysis. The results of data processing, seven dimensions of proposals and indicators are obtained. These dimensions are the basic components of indoor quality and security; waste management and safety; water efficiency management and artificial lighting; suitability of furniture work area and material; application of sensory technologies and health; the convenience of workspace; and mechanical ventilation and supporting facilities. These dimensions and their indicators are expected to be used as a valuation model to identify that buildings have met the green ergonomic building assessment requirement.","PeriodicalId":471454,"journal":{"name":"JRSI : Jurnal Rekayasa Sistem & Industri","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136301178","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}

To overcome this problem, many algorithms have been used in decision making. In this paper we have carried out the identification of planning team needs and the optimization of the bidding scheme using key requirements to minimize the influence of quality perceptions. The Kano Model Analysis method, the Analytical Hierarchy Process and Technique for Order Preference by Similarity to the Ideal Solution are used to analyze and determine the key requirements in the bidding process for telecommunications equipment needed by the planning team. Vendor selection based on key of requirements specifications is carried out in six stages, namely the preparation stage, requirements search, selection of Key of Requirements specifications, vendor selection, accuracy testing and conclusions. The results of the analysis show that the need for new planning and architecture of telecommunication service providers can increase to NFVi and services. An important criterion for NVFi (Hardware) development is Virtual Infrastructure Management (VIM) with a weight of 22%, while the service criteria are Fixed Services with a weight of 50.94%.

The company applies a flow shop production model whose production pattern is line to line in series using the First Come First Serve production scheduling method. The problem with the FCFS method which is considered to have not reached the optimal enough in meeting uncertain product demands, causing delays in the production schedule, which has an impact on the flow or distribution of goods and can lead to increased production in activities. The proposed improvement method is made to optimize production scheduling, focusing on minimizing the makespan values in the scheduling system's order. This study uses a heuristic approach to the Campbell, Dudek, Smith (CDS) algorithm in overcoming scheduling problems. The CDS method is a production scheduling heuristic method developed from the Johnson algorithm in obtaining several sequences of 6 types of work processes at the work center which aims to analyze the total time for each processing process (makespan). Comparing the two methods using the FCFS method by sorting the scheduling according to the order of the initial order time produces a total value of 2,408.75 minutes, while using the CDS algorithm which uses 5 iterations produces a minor matter of 881.3 minutes. Comparing the results obtained by applying the scheduling system with the CDS method can be used as a proposed improvement in overcoming the delay in delivery and the production scheduling process.","PeriodicalId":471454,"journal":{"name":"JRSI : Jurnal Rekayasa Sistem & Industri","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136301006","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}

There is a phenomenon that often occurs in one of Store X's branches, such as the shortage of jetblack hijab products in stock. This phenomenon results in the company's loss of opportunity to gain profit and has an impact on high inventory costs. Based on this, it is known that one of Store X’s branches does not yet have a good inventory system, so it is necessary to apply optimal inventory methods and minimize inventory costs. This study uses a quantitative approach to data collection methods of interviews, literature studies, and company historical data. The data analysis method used is the SMA, WMA, and SES methods with each of the two conditions. As well as using the Continuous Review System method (Q method) and the Periodic Review System method (P method) for the calculation of inventory policy and total inventory costs. Based on the results of the study, it was found that the Q method determines the optimal ordering lot quantity and the point of having to reorder goods. This resulted in the stock in the warehouse always being replenished on time so that there were no excess or shortage of inventory and customer requests could be fulfilled so that inventory costs could be minimized. Based on this statement, it is stated that the Q method is suitable for the company because it provides an optimal inventory policy and minimizes inventory costs by 5.90% or IDR 44,771,467 of company costs.","PeriodicalId":471454,"journal":{"name":"JRSI : Jurnal Rekayasa Sistem & Industri","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136301001","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}
