This specifically goes to the automobile manufacturers and engine rebuilders of Ghana. Though agile and very skillful in rebuilding engines many have reported grievances on their service renders to them. This shows that, the knowledge and zeal to rebuild it puts the industry at a certain level but needs further additional and requisite tuning to reach the pinnacle. For this reason, the researcher therefore sought to investigate how cylinder bores and piston ring end-gap contribute to the failure of locally rebuilt engines. A descriptive design was used for the study and sample of 60 participants responded to the structured questionnaire. The study used primary data to provide reliable and up-to-date information the researcher needs for the analysis. The data were entered in SPSS with analysis performed using inferential and descriptive analysis methods. The findings of the study revealed that errors made in the work procedure had a stronger effect on the clients’ than its other counterpart.

The Internet itself is a form of utilization of a computer network system, a computer network system consisting of a group of computer systems and other computing hardware linked together through communication channels to facilitate communication and resource sharing among various users. TCP / IP is a standard protocol that is applied to the internet network. The existence of a router in a TCP/IP network is very important, this is due to the large number of hosts and the differences in the devices used on a TCP/IP network. Router is a computer network device that is used to forward data packets from one network to another, both within the scope of LAN and WAN networks (Yani A., 2008). As a result, a routing mechanism is needed that can integrate many users with a high degree of flexibility. Routing is generally divided into two categories, namely static routing and dynamic routing. Static routing is a routing mechanism that depends on the routing table with manual configuration while dynamic routing is a routing mechanism where the routing table exchange between routers on the network is carried out dynamically. Routing in the world of information technology (IT) is part of how to improve network performance. Routing is a process to choose the path (path) traversed by the packet. Routing itself is very instrumental in building a network, be it LAN or WAN. Currently the use of routing in a network is something that needs to be taken into account in a company. Today's companies that have business processes in the IT sector are very dependent on network availability. Network reliability is the main point in the operation of the system. An adequate and reliable network infrastructure is very much needed by the company, especially regarding the company's electability. Companies that have large-scale networks need several techniques so that the network can work optimally and reliably in overcoming various problems that arise, including network connectivity that is still not stable and link redundancy has not been implemented as a backup path to overcome network failures if interference occurs. alternative network paths that are used to increase network availability, so that if there is a broken link in a network, the data path can still be connected without affecting the connectivity of devices on the network </em></p> 2022-06-24T00:00:00+07:00 Copyright (c) 2022 Journal of Applied Engineering and Technological Science (JAETS) https://yrpipku.com/journal/index.php/jaets/article/view/771 Implementation of Quality Improvements to Minimize Critical to Quality Variations in Polyurethane Liquid Injection Processes 2022-06-29T12:07:01+07:00 Nazaruddin Nazaruddin nazarhasibuan10@gmail.com <p><em>PT Topjaya Antariksa Electronics is a manufacturing company that produces various refrigerators, home freezers, and showcase refrigerators.

This study aims to plan improvement efforts to reduce process failures in the polyurethane shop and then evaluate the results of implementing the proposal. The FMEA (Failure Mode and Effect Analysis) method is used. This method performs several stages, such as determining the potential failure mode in each process, identifying the cause of failure, and then making a priority order. Process failure in this polyurethane shop is the most significant process failure compared to other shops. This failure causes the defects in the process at the polyurethane shop to be higher than in other shops. In 2019, 2020, and 2021, the number of refrigerator cabinets in the flawed polyurethane injection process amounted to 7,666 units, 8,256 units, and 8,014 units.

Before distributing the questionnaires, an instrument test such as the Gregory test will be carried out by involving system experts and linguists. Then a validity test will be carried out, a reliability test will be carried out after that a heuristic test is carried out by distributing questionnaires. Based on the calculation results that the lowest percentage is owned by the visibility of the system status variable by 75% and the highest percentage results in the match between the system and the real world and consistency and standard with the same calculation results obtained by 81%. The results of the analysis show that the tracer system of Universitas Lancang Kuning has high usability with an average percentage of 78%.</em></p> 2022-06-30T00:00:00+07:00 Copyright (c) 2022 Journal of Applied Engineering and Technological Science (JAETS) https://yrpipku.com/journal/index.php/jaets/article/view/790 User Satisfaction Analysis f Service Quality Of Dapodik Applications (Educational Data) Using Servqual Method 2022-07-02T11:45:30+07:00 Rizki Novendra rizkinovendra@unilak.ac.id Nizwardi Jalinus rizkinovendra@unilak.ac.id Waskito Waskito rizkinovendra@unilak.ac.id Afriansyah Afriansyah rizkinovendra@unilak.ac.id Anna Rasfira rizkinovendra@unilak.ac.id <p>Dapodik is an education data system with a national scale in which there are various kinds of information regarding educational data units. The problem that occurs is that the operator has difficulty if the input data is invalid, so to correct the invalid input data, it is done in the operator's account, while to synchronize the data the operator must first login to the principal's account. In addition, for filling the infrastructure (facilities and infrastructure) operators have difficulty measuring the percentage of damage that occurs to school facilities because they are not in their expertise or field. Therefore, this dapodik application needs to be measured user satisfaction with the quality of its services using the servqual method. This study aims to measure user satisfaction in using the dapodik application on the quality of its services using the servqual method. The results of the measurement can be concluded that the empathy dimension, H5 (-1.03) should be further improved because the value of user dissatisfaction is higher. In addition, based on tangible values, reliability, responsiveness and assurance are still not good, so it is necessary to improve the quality of dapodik application services.</p> 2022-06-30T00:00:00+07:00 Copyright (c) 2022 Journal of Applied Engineering and Technological Science (JAETS) https://yrpipku.com/journal/index.php/jaets/article/view/813 Application of Savonius Type Turbine Technology for The Conversion of Low Speed Wind into Electrical Energy at Wong Polo Beach Kota Pari Village Indonesia 2022-07-21T15:21:16+07:00 Parlin Siagian parlinsiagian@dosen.pancabudi.ac.id Hamdani Hamdani hamdani@dosen.pancabudi.ac.id M. Erpandi Dalimunthe erpandi@dosen.pancabudi.ac.id <p>Utilization of the potential that exists in tourist attractions aims to increase the savings in expenses that must be borne by the community to manage tourism. The beach is a place that is rich and abundant in wind potential that can be used to drive wind turbines. To take advantage of the existing wind potential, of course, we must know how the wind potential is in the form of wind speed and locations that have wind speed potential and how to use it as energy to drive wind turbines. To obtain the potential of wind energy and utilize it, wind speed measurements are carried out using a digital anemometer and recorded for some time. The position of the measuring instrument installed must be protected from wind obstacles so that it is installed as high as 20 meters above the ground in an open position against the direction of the incoming wind. From the measurement results over a period of one day, the wind speed varies and changes at any time and the maximum value is 6 m/s during the day starting at 10:00 to 04:00. The wind speed profile obtained is analyzed and the type of turbine is determined according to the low wind speed below 10 m/s. From the analysis results, the appropriate turbine is the Savonius VAWT type and can produce electrical energy of approximately 2.43 Watts with a diameter of 0.11 m. The use of turbines for wind at low speeds will still have the potential to generate small-scale electrical energy for communities in coastal areas</p> 2022-06-30T00:00:00+07:00 Copyright (c) 2022 Journal of Applied Engineering and Technological Science (JAETS) https://yrpipku.com/journal/index.php/jaets/article/view/832 Web-Based Batik Clothing Information System on Cv.

The purpose of this research is to find out the factors for the success of a construction project and the extent of the influence of these factors on the success of the project, especially the implementation of construction in the district of West Lombok and the city of Mataram. The ultimate goal of this research is to provide tools for parties involved in the implementation of construction, to predict project success and provide useful information in allocating resources to produce satisfactory results. This research consists of two stages, namely the pilot study and the second stage of research. In the pilot study in the form of a questionnaire containing questions referring to Chan's research (1998), it has succeeded in obtaining data from 60 respondents from business practitioners in the construction service sector in the district of West Lombok. Mataram city. The second phase of the questionnaire obtained data for 52 respondents consisting of project owners, professional practitioners, both consultants and contractors. The mean value of the tap factors from a total of 44 variables resulted in the 15 factors with the highest ranking. The fifteen factors were analyzed by step wise multiple regression to determine the extent of the influence of each factor on the project's success criteria. The six most dominant factors influencing project success are the project owner's emphasis on time, quality and cost of supervision, involvement with the implementation team from the start, health &amp; safety programs supported by the parent company, and relationships with fellow business associates.The results of the study prove that the project design factors that are adequate enough to be carried out at the construction implementation stage are the factors that most influence the project's success, followed by supervision at the construction implementation stage running well, the project team's technical ability, communication between the parties involved in the implementation. construction, and regular coordination.</p> 2022-06-30T00:00:00+07:00 Copyright (c) 2022 Journal of Applied Engineering and Technological Science (JAETS)
