In fulfilling customer demands, this SME produces sugar using a make-to-order system. Based on initial observations, indications of bottlenecks were found in the production process. The indications of bottleneck were found in the cooking process as this process is repeated and takes a long time. The prolonged cooking process results in the subsequent process stopping because there are no products to process. In addition, signs of bottleneck also occurred in the printing process, which takes a long time. After identification, the bottleneck occurred at workstation 4 where the cycle time at workstation 4 exceeded the production takt time. The bottleneck caused the company to experience delays in meeting production targets. To improve the bottleneck problem, workstation balancing was done using the rank positional weight method. The RPW method is a heuristic method that has advantages in terms of performance and is easy to apply to real problems. The results of the improvement were then simulated using Extend software. Line balancing with the RPW method resulted in 2 proposed workstation allocations. The first proposal divides the workstations into 5 workstations with idle time calculation results of 157.3 minutes and line efficiency of 65%. The second proposal divides the workstations into 5 workstations with idle time calculation results of 57.31 minutes and line efficiency of 84%. Based on the simulation results, no bottleneck was found in both proposals, with the first proposal producing an average output of 3.7 batches while the second proposal producing an average output of 4.1 batches. The recommended improvement proposal is to allocate workstations according to the second proposal.","PeriodicalId":512976,"journal":{"name":"Engineering Headway","volume":"161 1‐3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140698453","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}

WHO notes, deaths caused by cancer will reach 10 million cases in 2021. Of many cancers, breast cancer is a cancer with the most cases. Early diagnosis of breast cancer plays an important role in the treatment process. Various imaging methods, including magnetic mammography, are used to diagnose breast cancer. With the help of machine learning, the process of diagnosing breast cancer with mammography images is more precise and accurate. Various machine-learning methods have been developed by researchers to diagnose breast cancer. Among them is a deep learning method that can achieve good feature representation and can solve the problem of image classification and object localization. Through a systematic literature review, this research collects and analyzes related studies regarding the classification of breast cancer that have been done previously. Several aspects that will be evaluated include the methods used, data sources used, and accuracy of the method used. This research is expected to provide clear knowledge about the advantages and disadvantages of using artificial intelligence techniques for breast cancer classification. The results of this study can provide insight for researchers and medical practitioners in the further development and application of deep learning methods in the diagnosis and classification of breast cancer.","PeriodicalId":512976,"journal":{"name":"Engineering Headway","volume":"34 S132","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140694636","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}

By using the DFMA method to find proposals for the production process, the process of making a design proposal is not much different from the process of making a set of chairs and a dining table made of wood; it's just that there are some differences due to the different materials used, so that the types of tools and assembly materials are different. The cost of goods sold obtained for making a set of chairs and tables consisting of 2 chairs and 1 table is 987,333.73.

Starting from the design planning stage, design testing/ experimentation, design analysis, selection of the best design, to design implementation. This research was conducted to evaluate workspace designs using the Taguchi method. In this study, four factors were determined as elements of the workspace environment: the level of lighting, noise, temperature, and aroma of the room. Taguchi orthogonal array design produces 8 experiments obtained from a combination of 4 factors and 2 levels. Experimental activities in the form of the influence of the physical work environment on the resulting typing speed. The research sample in each experiment was 30 responses. The experimental results were analyzed using the Taguchi method with the help of Minitab software. In the analysis of the larger the better factor, based on the ranking, it is found that three factors have amajor influence on typing speed: lighting using room lights, not adding sound (noise), and regulating the room temperature to keep it cool. The ANOVA results show that lighting, noise, and temperature factors significantly affect typing speed. It is known that the calculated F value of the lighting factor is 42.10, noise is 12.22 and temperature is 14.45, all of which are greater than the F table of 4.07. The results of this study can be used as managerial evaluation material for companies to design workspaces by prioritizing bright lighting, not too noisy, and cool temperature of room.","PeriodicalId":512976,"journal":{"name":"Engineering Headway","volume":"72 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140694854","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 are many debates about similarities between those holy scriptures from many famous preachers and scholars. Technology can be used as an alternative solution to solve these problems. There are at least two overall approaches to determine text-similarity; the vector space model and semantic similarity —define the similarity or the distance. The similarity between words is often represented by a similarity between concepts associated with the words. This paper presents a method for identifying semantic sentence similarity among each sentence from each dataset using semantic relation of word senses between different synsets using WordNet path similarity and Wu-Palmer similarity. This method is also evaluated and has acceptable accuracy. Although both Path Similarity and Wu-Palmer Similarity successfully identify the similarity between two sentences; still, they have slightly different accuracy. The Wu-Palmer similarity is superior to path similarity when identifying sentences between Quran Sahih International and An-Nawawi Forty Hadith Translation. Looking ahead, we might be able to improve our results by using multipliers such as reverse document frequency (TF-IDF), combining the results of several steps in WordNet similarity, using vector space models, and optimal matching methods.","PeriodicalId":512976,"journal":{"name":"Engineering Headway","volume":"23 5‐6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140698435","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}
