Primary and secondary data were collected using both open and closed-ended questionnaires. Welders and fabricators of Sarkyoyo enterprise at the Suame Spare parts dealership area in Kumasi were engaged in the survey. The elastic strain and stress mathematical models were used to determine the stress points in a loaded leaf spring with the aid of ANSYS. The factors considered in the analysis were the leaf spring SAE design specification, the recommended Ghana Highway Authority load limit for heavy-duty vehicles, and the terrain. Analysis was done for both the standard and variable curvature leaf springs. The mode of failure was found to be fatigue loading. The causes of failure were determined to be loaded beyond the recommended 43 tons per wheel limit, bad roads, and reckless driving. It was also observed that loading causes the edges of the leaf spring to bend outwardly from the top, making the edges more prone to failure. Results further showed that the leaf spring with variable curvature recorded strain energy 2.5 times higher than the standards leaf spring.</p> Prince Yaw Andoh L D Mensah D E K Dzebre Kofi Owura Amoabeng Charles Kofi Kafui Sekyere Copyright (c) 2022 Journal of Applied Engineering and Technological Science (JAETS) 2022-08-16 2022-08-16 4 1 1 15 10.37385/jaets.v4i1.508 Finite Element Analysis of SS316L-Based Five-Hole Plate Implant For Fibula Reconstruction <p><em>This study analyzed the design performance of SS316L-based plate implant for fibula restoration using a Finite Element Analysis approach. The simulated model design has dimensions of 35 x 5 x 1.5 mm and five holes with 2-3 configuration. The results of the bending test simulation showed that the values for both displacement and Von Mises stress that occurred (0.008 mm and 116 MPa of each) were still considerably below the yield stress of the SS316L material. The same results were also shown in the tensile test simulation, although the clamping setting on the plate was changed on the other side. From this finite element analysis approach, the SS316L-based five-hole plate implant design has a fairly good strength performance as a fibular bone-implant restoration product.</em></p> Nanang Qosim Zakki Fuadi Emzain AM.

The guava itself has a soft and dense flesh texture compared to water guava. The guava itself has a pink color if it is raw but if the guava is ripe it will be dark red. From a glance, when viewed from human vision, it is very easy to distinguish between them, but from most people it is still difficult to distinguish which guava is ripe, half-ripe and unripe guava because of differences in opinion from one human eye to another. Based on these problems, researchers have developed a system that is able to detect the maturity level of guava fruit by utilizing the Hue Saturation Value (HSV) feature extraction with K-Nearest Neighbor (KNN). The data used in this study were 465 datasets which were divided into 324 training data and 141 test data. The data had classes, namely ripe, half-cooked, and raw.

The use of Artificial Intelligence in helping humans in dealing with problems is growing. Humans can take advantage of computer/smartphone media in today's technological era. One of its uses is Optical Character Recognition. This research is motivated by the problem where the running system requires development in terms of technology to detect characters in the quote text image, because the previous system still performs manual input. Optical Character Recognition has been widely used to extract characters contained in digital image media. The ability of OCR methods and techniques is very dependent on the normalization process as an initial process before entering into the next stages such as segmentation and identification. The image normalization process aims to obtain a better input image so that the segmentation and identification process can produce optimal accuracy. To get maximum results, it takes several pre-processing stages on the image to be used. To achieve this, it is necessary to perform Optical Character Recognition which can be done using Tesseract-OCR. The OCR program that was created was successfully used to scan or scan a quote text image if the document was lost or damaged, and it could save time for creating, processing and typing documents.</em></p> Ikha Novie Tri Lestari Dadang Iskandar Mulyana Copyright (c) 2022 Journal of Applied Engineering and Technological Science (JAETS) 2022-09-02 2022-09-02 4 1 58 63 10.37385/jaets.v4i1.905 Classification of Maturity Levels in Areca Fruit Based on HSV Image Using the KNN Method <p>Areca nut (Areca catechu) is a kind of palm plant that grows in Asia and Africa, the eastern part of the Pacific and in Indonesia itself, areca nut can also be found on the islands of Java, Sumatra and Kalimantan.

Every day humans will produce waste, both industrial waste and household waste in everyday life. Garbage will become an environmental problem because it can interfere with human health, cause bad smells and even air pollution. Poor waste management causes harmful and unhealthy environmental problems. Sometimes people are reluctant when they want to dispose of garbage by opening and closing the trash can so it is feared that they will get bacteria on their hands. The problem of environmental waste can arise from waste management that unites all types of organic and inorganic waste in the same place, making it difficult to recycle waste. Another problem is that sometimes the cleaners are negligent in emptying the full trash can, so it will cause a bad smell. Based on the above problems, it is necessary to make a smart trash bin which will later be able to sort out the types of organic and inorganic waste. The lid of the trash can will open automatically when someone wants to throw out the trash and it will close automatically when it's finished taking out the trash. With the waste sorting technology, it will automatically reduce environmental pollution by waste, and facilitate waste management so that it can be recycled again. To overcome the bins that are full for too long, if the trash is full, it will automatically notify the cleaners via Telegram messages. From the test results, it can be concluded that the ultrasonic sensor can detect if someone is approaching with a maximum distance of 50 cm so that the cover can be opened automatically for 7 seconds. The servo motor can rotate the waste sorter according to the type of organic or inorganic waste based on the detection results of the capacitive proximity sensor. The telegram message has been successfully sent if the garbage condition has been fully detected through the ultrasonic sensor. LCD can display the type of organic or inorganic waste accurately.</em></p> Aldiga Rienarti Abidin Yuda Irawan Yesica Devis Copyright (c) 2022 Journal of Applied Engineering and Technological Science (JAETS) 2022-09-29 2022-09-29 4 1 202 208 10.37385/jaets.v4i1.1015 Application of Pregnant Mom's Diet Based on Raspberry PI Using Telegram Chatbot <p>A healthy and regular diet is needed to maintain the body's immunity, the benefits that can be used for mothers and fetuses to help in the growth and development of the fetus in the mother's womb so that the eating patterns that are consumed must have good quality and nutrition, because good diet can be increase the development of the fetus while in the womb, so it is necessary to make an application with the aim of providing information on a dietary pattern of raspberry-based pregnant women using the telegram chatbot.

KEN is an implementation of the mandate of Law no. 30 of 2007 concerning Energy. Apart from being used as primary energy for power generation, NRE is also being developed as energy that is used directly by the user sector. At this time the type of EBT that is most widely used by users is PLTS, in addition to its simple construction and heat sources can be obtained anywhere, this is also the government's recommendation to achieve the PLTS development target. In fact, until now, consumers are still very less willing to use PLTS in meeting their electrical energy needs, this is due to several problems, including the high cost of PLTS construction, besides that the material costs are also relatively expensive. In this study, an overview of the calculation of how much cost can be saved or saved if the energy source used is a Hybrid between PLN and PLTS 500 Wp which is used alternately in supplying the electrical load of a simple house. with specifications of 2 solar panels of 250 wp each, 2 batteries of 100 Ah each, 130 solar panel control and 1300 watt inverter. The cost of electricity charges paid monthly before using PLTS Roof ranges from 300 to 400 thousand rupiah, After using PLTS Roof, the monthly electricity costs are 200 to 300 thousand rupiah, the average monthly savings is 100 thousand rupiah, if you take into account the investment costs will return in 1 year, the average material life of PLTS is around 20 years. The cost savings in electricity costs are around Rp. 22.800.000,- in 20 years.

Because of the diverse and frequently shifting message patterns on this social media, it is extremely challenging and time-consuming to manually identify topics from a collection of messages. Topic modeling is one method for obtaining information from social media. The model and visualization of the results of modeling topics that are discussed on social media by the Makassar community are the goals of this study. The Latent Dirichlet Allocation (LDA) algorithm is used to model and display the results of this study. The modeling results indicate that the eighth topic is the most frequently used word in a conversation. In the meantime, the 7th and 6th topics emerged as the conversation's core based on the spread of the words with the highest term frequency.

This cooperative operates in the storage of pure cow's milk with a total of around 300 milk farmers located around the cooperative. The problem that often arises is the dependency on receiving milk by the milk factory. Milk that has been sent to the dairy factory can be rejected by the milk factory for various reasons. In the field of marketing, KSU SN established a business entity with the name CV MSN which is located on Jalan Tirto Agung, Semarang. Product delivery logistics activities have so far been carried out with four-wheeled vehicles and using two-wheeled vehicles. To transport milk, each driver uses a bag or styrofoam which is used to transport milk products. Apart from being impractical, the transport process is messy, and the milk temperature cannot be maintained. To overcome this problem, milk transport boxes are designed to be able to transport milk more effectively, maintain product temperature, be ergonomic and increase the capacity of milk that can be distributed because previously they used boxes made of cork or styrofoam.

Currently the production of light bulb waste reaches 4.50% of the total waste production per day. These conditions require a solution to reduce the amount of waste produced by light bulbs. This paper aims to discuss the recycling technology used for light bulb waste, so that the waste can be reused as recycled and environmentally friendly lighting lamps. The method used in this study refers to an environmentally friendly concept, namely, designing lighting lamps using waste light bulbs that are no longer used. The design product is designed exactly the same as the previous product from the manufacturer, then proceed with testing in the laboratory to determine the electrical parameters and the amount of lumens produced. From the results of the research conducted, it can be seen that the results of the design of recycled lighting lamps have a decrease in lumens value for CFL types by 7%, LED by 8%, the durability and lifespan of light bulbs are reduced by CFL types by 32%, LED types by 30%, the results of the design recycled</p> Siti Anisah Rahmadhani Fitri Zuraidah Taro Rian Farta Wijaya Copyright (c) 2022 Journal of Applied Engineering and Technological Science (JAETS) 2022-12-15 2022-12-15 4 1 568 577 10.37385/jaets.v4i1.1287 LTE Optimization Using The Electrical Tilt Method At The Mandau Site <p><em>Long Term Evolution (LTE) has high-speed data access of 300 Mbps on the downlink and 75 Mbps on the uplink. The area of ??the Mandau site is located in the town of Duri-Bengkalis, Riau. In this study, a network optimization was carried out on one of the providers. From the results of the drive test conducted, a problem was found, namely throughput quality which was in very bad condition. Therefore, a network optimization simulation was carried out using the Electrical Tilt method in order to overcome the problem of unstable throughput conditions. Simulation of the application of this method is carried out using Software Atoll. The results obtained after optimization with the value on Jalan Obor 2 increased to 19,000 kbps (normal), on Jalan Obor 1 increased to 50,000 kbps (very good), on Jalan Bandes increased to 50,000 kbps (very good), on Jalan Swadaya increased to 50,000 kbps (very good) and on Jalan Hangtuah increased to 50,000 kbps (very good).</em></p> Mhd Azwar Taruna Mulyono Mulyono Rika Susanti Sutoyo Sutoyo Copyright (c) 2022 Journal of Applied Engineering and Technological Science (JAETS) 2022-12-15 2022-12-15 4 1 578 585 10.37385/jaets.v4i1.1320 Sales Mobile Application Design in Handphone Store <p>In the current era of globalization, technology is advancing rapidly, and computers are one of the technologies which are one of the tools used to make it easier to find problems, of course, it is also supported by hardware, software and brainware. Mobile stores require an information system that supports and provides satisfactory service to buyers. For this reason, the author makes this final project regarding the program for selling cellphones at the cellphone store which currently does not use a computerized system. The system at the cellphone store usually still uses a manual system. Starting from recording sales notes to bookkeeping sales reports that are still recorded in the books. This can allow for errors in recording, ineffectiveness and inefficient calculations in large numbers. And can cause inaccurate reports made. The use of the program is one solution to solving sales problems in the cellphone store. Therefore, with the use of a sales program, it is possible to further assist sales activities in the cellphone store.</p> Nanang Nuryadi Bibit Sudarsono Ayuni Asistyasari Nuryanti Nuryanti Copyright (c) 2022 Journal of Applied Engineering and Technological Science (JAETS) 2022-12-15 2022-12-15 4 1 586 598 10.37385/jaets.v4i1.1371 Analysis of E-Library Based on Level of User Satisfaction Using EUCS and IPA Methods <p><em>technology, namely the use of e-Library as an online catalog facility to directly access collections of books, theses or other collections contained in the library. This research is based on the fact that users feel dissatisfied with the services provided by the e-Library, such as collections and collection information that do not meet user needs. The purpose of this study was to measure the level of satisfaction of e-Library users using the End User Computing Satisfaction method with five perspectives namely Content, Accuracy, Format, Ease of Use, and Timeliness. The Impotance Performance Analysis (IPA) method is used to determine which attributes are important to be improved and which need to be reduced to be interpreted in the form of a matrix. This study also calculates the value of Customer Satisfaction Index (CSI) to determine the overall level of user satisfaction. The results of this study show that all attributes in terms of Importance are in a very important category, while the Performance attributes are in the satisfied category, namely the Content and Format variables. Variables with quite satisfied categories on Accuracy, Ease of Use and Timeliness variables. The results of the IPA matrix obtained 6 attributes with the most improvement in the Accuracy variable, the attribute with the most good performance in the Content variable. Overall, the CSI value is 60.34%, which means that users are quite satisfied with the performance provided by the e-Library</em></p> Muhammad Luthfi Hamzah Lovi Anisa Hultari Astri Ayu Purwati Nazaruddin Nazaruddin Copyright (c) 2022 Journal of Applied Engineering and Technological Science (JAETS) 2022-12-30 2022-12-30 4 1 599 610 10.37385/jaets.v4i1.1426 Instrument Readiness Analysis of Technology-Based Businesses <p><em>Digital technology is currently highly developed in all fields.
