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. Practically, the flaws in the work procedure of rebuilding cylinder bore significantly affects clients’ satisfaction.</p> 2022-06-10T00:00:00+07:00 Copyright (c) 2022 Journal of Applied Engineering and Technological Science (JAETS) Expert System For Career Early Determination Based On Howard Gardner's Multiple Intelligence 2022-05-21T19:09:27+07:00 Rizky Ema Wulansari RH Sakti Ambiyar Ambiyar M.

To facilitate the watering of plants when farmers leave the city on agricultural land and know the level of soil moisture periodically, an automatic watering device based on IoT notification is made using the arduino Uno mikrocontroler. The whole tool is divided into several parts which consist of smartphone, esp, arduino uno revision three microcontroler, soil moisture,relay module, and pump. This tool works when the esp module connects to the internet, from esp then to siol moisture sensor if the level of moisture in the soil is detected below 70%, then provide information&nbsp; to the arduiono microcontroler to provide information on the humidity level to the LCD and the website as well as watering orders for plants. From the microcontroler then to the relay module to turn on the water pump. After the pump is running, the automation of the soil mositure sensor re-detects the soil moisture level, if it is above 70% then gives it again to the arduino microcontroler to give the command to turn off the pump. The results of the research show that esp can communicate well with arduino uno when it’s connected to the internet.</em></p> 2022-06-13T00:00:00+07:00 Copyright (c) 2022 Journal of Applied Engineering and Technological Science (JAETS) Analysis of The Noise Level of The Diesel Engine with 1100 RPM in The Indoor Condition 2022-03-21T21:46:24+07:00 Nanang Qosim <p>One of the weaknesses of diesel engines that most users complain about is the vibration and the noise. Therefore, it is very important to know the noise level of an engine in a room to consider the allowed duration of the exposure time, which is the aim of this study. The instrument used in this study was the Sound Level Meter, by first determining the radius of the hemisphere used in determining the location for the data collection. The measurement was carried out four times, where the largest value was considered as the main data, at four points. The result in this study indicated that the noise level of the diesel engine with a speed of 1100 rpm was 92.805 dBA with the background noise in the diesel engine room of 51.6 dB. Based on government regulations, the maximum exposure time to the noise at this level is 2 hours.</p> 2022-06-14T00:00:00+07:00 Copyright (c) 2022 Journal of Applied Engineering and Technological Science (JAETS) Application of C5.0 Algorithm in Prediction of Learning Outcomes in Calculus Subject 2022-06-12T13:23:04+07:00 Fida Nafisah Giustin Betha Nurina Sari Tesa Nur Padilah <p><em>Calculus is one of the basic subject that must be studied at the computer science faculty of the informatics engineering study program.

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)
