The use of additive manufacturing technology is increasingly being used by various companies around the world. Fused deposition modeling (FDM) is a type of 3D printing that falls under the category of material extrusion. It is also known as fused filament fabrication (FFF). Fused deposition modeling (FDM) is the most cost-effective additive manufacturing technique. Polylactic acid (PLA) is a type of plastic that is made from renewable resources such as corn starch, tapioca roots, chips or starch, or sugarcane. It is biodegradable and bioactive and can be used for a variety of applications such as packaging materials, disposable tableware, medical implants, and 3D printing. PLA is also used in the food industry as a food packaging material. The goal of this study is to analyse the warping angle of PLA. In this study, the commercial eSUN PLA filament manufactured by Shenzhen Essun Industrial with a diameter of 1.75 mm was used. This study used experimental method with predetermined conditions such as ISO 527-2 printed specimens, annealing temperature at 50⁰C and 70⁰C. The test result shows that annealing at 50⁰C have the highest degree of side view 1.88⁰, and 1.32⁰ on average. The top view have 2.21 ⁰ and 1.19 on average. Afterwards, the study shows that annealing at 70⁰C have the highest degree of side view 6.19⁰, and 3.96 on average. The top view have 3.84⁰, and 2.33⁰ on average.","PeriodicalId":13778,"journal":{"name":"International Journal of Applied Science and Engineering","volume":"147 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77552503","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}

Tempe is usually made by fermenting soybeans with mold under special conditions to become tempeh. In the fermentation process, tempeh producers need to monitor the maturity of the tempeh until it is suitable for consumption. To detect this maturity requires a separate effort, so that an image processing approach is proposed in this study with the support of feature selection. An image allows for various features to be taken, such as texture features using GLCM and various color features including RGB, HSV, LAB, CMYK, YUV, HCL, HIS, LCH. With so many features, it is necessary to do a selection so that computation in its classification becomes efficient. This study aims to classify tempeh fermented images using the Naive Bayes method with Linear Discriminant Analysis (LDA)feature selection for GLCM features and eight color features. Tempe fermentation image is divided into three classes, namely raw, ripe and rotten. Based on the experimental results, the average accuracy in the test is 84.06%. In testing the fastest time is 1.87 seconds and the longest is 2.20 seconds. This shows that the classification of fermented tempeh maturity with Naive Bayes with LDA feature selection can work well.","PeriodicalId":13778,"journal":{"name":"International Journal of Applied Science and Engineering","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72508976","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}

Both men and women are interested in buying skin care products. Moreover, there are many brands of skin care products that are divided into several types of facial and body care, such as moisturizers, toners, cleansers, and masks. Therefore, many consumers take the time to find information, for example, in terms of price, quality, and brand for decision-making. A lot of useful information is in the form of Twitter messages known as tweets which are sent from people who use skin care products because Twitter is one of the online social media where users can share their opinions and experiences. However, consumers still have to spend a lot of time searching, reading, and understanding the comprehensive collection of tweets before buying skin care products.The purpose of this study is to analyze customer experience, analyzing automated tweets about skin care products. Tweets about skin care products will be subjected to a topic modeling process to find out what topics are being discussed. In addition, the topics that have been obtained will be subject to sentiment analysis in the form of positive and negative messages for skin care products. Consumers who are app users don’t waste time reading and analyzing large amounts of data manually and they can decide to buy skin care products more easily.The results of this study obtained 14 topics of discussion related to skincare. Meanwhile, the sentiment analysis results of 14 topics resulted in more positive sentiment class tweets overall. It related the category topic that has the number of tweets to the importance of skincare. In addition, categories related to ingredients for skincare products from nature, namely fruits and spices, are the topics that have the second highest number of tweets. The results of the analysis of tweets related to user experience on Twitter, it was found that users prefer skincare products that use ingredients from nature.","PeriodicalId":13778,"journal":{"name":"International Journal of Applied Science and Engineering","volume":"206 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86840393","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 heat from the combustion reaction heats the surface of the pan, this occurs in the process of heat transfer by convection on the surface of the pan. The rooting reaction of LPG fuel produces a flow of combustion gas with a high flow speed. This will have the consequence that the heat wasted is very large while the absorbed is very small in the process of heating the surface of the pan. To increase heat absorption by the surface of the pan can be done by inhibiting the flow when the fire touches the surface of the pan. This study will examine how the effect of using a heat collection filter on the heat absorption efficiency of the flame of LPG fuel gas and aims to compare the heat absorption efficiency of a fuel gas flame using a heat collection filter with no heat collection filter (conventional). This study uses independent variables in the form of heat absorption without a heat collection filter and with a heat collection filter, as well as variations in LPG gas flow capacity. While the dependent variable observed is the heating time to obtain heat absorption efficiency.

Water electrolysis is one way to get hydrogen gas. This study aims to determine the results of water electrolysis with three catalysts and mixed metal electrodes which are then applied to generator motor engines. The research method used was an experimental method with variations in electrolysis using KOH and NaOH base catalysts, H2SO4 acid catalysts, and stainless steel 316 electrodes. The best results for H2 gas production in this study were obtained with a 2M H2SO4 catalyst with a gas yield of 244.9mL H2 gas, while The lowest yield in this study was the 1M concentration of 1M NaOH catalyst of 12.5mL. The best results for H2 gas production were varied with pertalite fuel and then tested with a generator engine. Testing the generator motor engine is measured arm length and mass with a machine dynamometer. After testing, the data is obtained which is then analyzed to obtain the value of torque (Nm) and electric motor power (kW), and driving motor power (HP). The maximum energy produced pertalite + H2 gas has increased by 2.27kW on the electric motor and power of 4.13HP on the driving motor, while for pertalite fuel alone the power generated is 1.44kW on the electric motor and power of 2.62HP on the driving motor.[1]        S.
