Along with technological developments, market developments are also increasing rapidly and competition is starting to occur between entrepreneurs and business people, which requires entrepreneurs to take advantage of existing technology. At this time the Universal Homeware Store does not realize that this data can be processed effectively to find out the development of a business or business that is being run, besides that the procurement of goods that customers need is often unavailable. One of the data processing technologies is by applying data mining. Data mining is a form of extracting information from data that is large enough to obtain data patterns so as to produce information data that is useful for making decisions and increasing profits in developing marketing strategies. One of the uses of data mining is using the Naive Bayes Classifier algorithm. Naive Bayes Classifier is one of the existing algorithms in data mining which is used to deal with uncertainty problems by emphasizing the concept of probability of use and measuring the level of accuracy so that it can predict purchasing strategies from past sales analysis. with research results Using 36 data and with rapid minner tools produces an accuracy value of 80%

Current technological developments have brought changes to human lifestyles, such as lifestyle, selection of antic goods and communication equipment such as smartphones and other devices. Nowadays it is known that the collection of branded items is also a lifestyle trend such as bags, rings, clothes and other fashions. Batam as an industrial city encourages investors to invest in Batam, because Batam is the most strategic city and is an international trade route directly adjacent to Singapore. The problem that often occurs at PT Tas Import Sukses in serving consumers is that the goods sent are not on demand, so consumers suspect that the products traded do not have good quality. And if there is a problem, the company responds with a very slow time. The purpose of this study is to analyze consumer satisfaction with the quality of products at PT Tas Import Sukses using the Naïve Bayes method, to determine the level of consumer satisfaction with the quality of bag products. And the last is to find out the level of accuracy in determining product satisfaction and quality with the Naïve Bayes method. While the results of this study are that satisfaction is strongly influenced by the level of service, while the second order is product quality, where the average level of satisfaction accuracy using the naïve bayes algorithm is 91%, pression 89% and recall 88.33%.
当前的科技发展给人类的生活方式带来了改变，比如生活方式、对古怪商品的选择和通讯设备，比如智能手机等设备。如今，众所周知，收集品牌物品也是一种生活方式的趋势，如包包、戒指、衣服和其他时尚。巴淡岛作为一个工业城市鼓励投资者在巴淡岛投资，因为巴淡岛是最具战略意义的城市，是直接毗邻新加坡的国际贸易路线。PT Tas Import Sukses在服务消费者时经常出现的问题是，所送的商品不是按需的，因此消费者怀疑所交易的产品质量不好。如果出现问题，公司的反应速度非常慢。本研究的目的是使用Naïve贝叶斯方法分析消费者对PT Tas进口Sukses产品质量的满意度，以确定消费者对袋产品质量的满意度水平。最后是利用Naïve贝叶斯方法确定产品满意度和质量的准确度。而本研究的结果是满意度受到服务水平的强烈影响，而第二级是产品质量，其中使用naïve贝叶斯算法的平均满意度水平准确率为91%，减压率为89%，召回率为88.33%。

This study aims to analyze the risk level of Musculoskeletal Disorders (MSDs) in workers who carry out Manual Material Handling (MMH) activities at PT JMS Batam. MMH is a manual transportation and material transfer activity using human labor. This study was conducted because MMH activities carried out repetitively often cause health complaints, especially in the skeletal muscles. The primary data collection method is carried out through observation, direct interviews with employees, documentation using mobile phone cameras, and the distribution of Nordic Body Map (NBM) questionnaires to identify complaints on workers' body parts. The Rapid Entire Body Assessment (REBA) method is used to assess the posture of workers during MMH activities. The results showed that Nordic Body Map analysis showed that all stevedoring workers had the potential to experience musculoskeletal disorder complaints, especially on the left shoulder, right shoulder, back, waist, and buttocks. Workers with scores above 70 are at high risk and need immediate improvement. Workers scoring 55-70 are at moderate risk and require consideration of future improvements. Analysis using the REBA method showed that material transfer has a high risk of trunk and upper arm posture, increasing the risk of injury and health problems.

Technological advancements continue to progress rapidly, allowing experts to enhance their knowledge across various industries, including health, network security, and others. PT Air Batam Hulu is a water company situated at Building A-WTP Moya Muka Kuning Jl. Letjend Supranto in Batam, responsible for managing the security of drinking water. However, the company's existing system is susceptible to data security breaches due to unauthorized hacking attempts. In addition, computer network systems face both physical and logical threats, such as Sniffer, Spoofing, Preaking, Remote Attack, Hole, Hacker, Cracker, and more. Among the current successful hacking attempts, UML sites, Malware, Trojans, Viruses, and port scanning are commonly encountered. To address security concerns, the company implements a security system called "port knocking," which involves opening or closing access to specific ports through the use of a firewall on network devices. This system works by sending certain packets or connections, including TCP, UDP, and ICMP protocols. To gain access to restricted ports, users are required to perform a "knocking" action by inputting the necessary rule beforehand. This ensures that only authorized users can access and use specific ports, enhancing data security and reducing the risk of unauthorized infiltration.
技术进步继续快速发展，使专家能够提高他们在各个行业的知识，包括卫生、网络安全等。PT Air Batam Hulu是一家水务公司，位于Moya Muka Kuning jr . a - wtp大厦。巴淡岛的Letjend Supranto，负责管理饮用水安全。然而，由于未经授权的黑客攻击，该公司现有的系统容易受到数据安全漏洞的影响。此外，计算机网络系统面临着物理和逻辑威胁，例如嗅探器、欺骗、伪造、远程攻击、漏洞、黑客、骇客等。在当前成功的黑客攻击中，经常会遇到UML站点、恶意软件、特洛伊木马、病毒和端口扫描。为了解决安全问题，该公司实施了一种称为“端口敲门”的安全系统，该系统涉及通过使用网络设备上的防火墙打开或关闭对特定端口的访问。该系统通过发送某些报文或连接来工作，包括TCP、UDP和ICMP协议。为了获得对受限端口的访问权限，用户需要通过事先输入必要的规则来执行“敲门”操作。这样可以确保只有授权用户才能访问和使用特定端口，增强数据安全性，降低未经授权的渗透风险。

PT ABC is a manufacturing company engaged in canned food products. PT ABC produces several types of ready-to-eat food cans ranging from small to large sizes. Based on field studies, several problems were found in the can lid, where the can lid is often difficult to open, causing pain when opening the can lid. Another problem is the side of the can cover that is too sharp, causing cuts when hit by the side of the can cover when taking food. Therefore, it is necessary to redesign a safe food can lid to maintain user safety. The method used in this research is the NIDA method (Need, Idea, Decision, and Action). Based on the research results, there are 2 alternative forms of can lid design. The first alternative provides an increase in the distance between the puller and the lid of the can by 2mm and adds a curve to the side of the can cover in the form of a radius of 0.3mm. While the second alternative adds a distance between the puller and the lid of the can by 2mm and adds an arch on the side of the can cover in the form of an angle of 60 °. Based on the results of the analysis of the two alternatives, the first alternative was chosen as a safe form of can lid design.

While the second alternative adds a distance between the puller and the lid of the can by 2mm and adds an arch on the side of the can cover in the form of an angle of 60 °. Based on the results of the analysis of the two alternatives, the first alternative was chosen as a safe form of can lid design.","PeriodicalId":500489,"journal":{"name":"Computer and Science Industrial Engineering (COMASIE)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135045713","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}

All products must have aesthetic value in order to attract customer interest, one of which is to apply color coating by carrying out the painting process. This research was conducted at the painting department at PT XYZ where the color coating process on nonflip bof products was carried out without the use of tools according to product specifications, as a result the product fell due to wind pressure from the spray gun causing the nonflip bof product to become deformed and the target was not reached. Based on this, the researcher intends to conduct research on the design of work aids for the painting process of nonflip bof products using the Design for Manufacturing and Assembly (DFMA) method. Based on the DFMA analysis, the design of this tool was assembled with a total of 10 components and a manufacturing cost of IDR 2,608,163 and a manufacturing time of 3.82 hours. From the test results after using the tools from the design results, it was found that the painting process of nonflip bof only took 3.64 minutes for one time painting process of 20 units of nonflip bof products with a total output of 1 working day producing 1,860 units.
