Abstract

The Williamson’s self-rating scale for self-directed learning (SRSSL) questionnaire is applied to determine which learning strategies first-year African engineering students have adopted at the start of a problem-based learning module that is designed to promote self-directed learning (SDL). This approach can help academics to better identify “who” their students are, thereby helping them to leverage and improve on current learning strategies to try and enhance student engagement. A requirement for becoming a great teacher in one’s field of study is to come to know your students cognitively, affectively, and culturally. Many different cultures have strongly embedded identities that would form and shape student learning strategies. Intended outcomes: The purpose of this article is to identify what self-perceived learning strategies engineering students have adopted from their school education, by using a standardized questionnaire. Student perceptions regarding their own levels of SDL, as well as their expectations and actual achievements of academic success, are also presented. The purpose of the problem-based learning module that is used in this study is to give engineering students the opportunity to develop managerial skills as the module involves much teamwork, where imaginary companies are formed with the goal of designing and constructing specific projects for real industry-based clients. A time-lag study is used where quantitative data are collected using a standardized questionnaire. Results indicate that 77% of females report high levels of SDL, while only 66% of males do so. No significant correlation exists between the self-reported scores of the students and their final grades. However, the three most reported learning strategies include interactive teaching and learning sessions, simulations, and educational interactive technologies. It is recommended that academics encourage SDL among first-year engineering students by helping them to identify appropriate learning strategies that can help them to enhance their engagement with the course and subsequent academic success.

Abstract

Frequent floods in Indonesia cause many problems, therefore it is necessary to create devices with the implementation of Raspberry Pi-based IoT Gateways in the LoRa communication system. The gateway has a function as a performance informer and makes it easy to access the exchange of information data and the space to store a lot of data received from the node. To maximize the implementation, a Gateway was designed consisting of Raspberry Pi 3 B+, ESP-32, and LoRa 433 MHz. This research uses the Research and Development method. The data obtained includes how the Gateway works which will be displayed on the Raspberry Pi screen properly, monitoring the state of the water using Thinger io. Data were obtained from the Gateway and data transmission system from Gateway to Client as much as 42 times with an RSSI value of -53.3 dBm in very good condition at a distance of 1.54 km with a wajanbolic antenna and a very poor RSSI of -91.4 dBm at a distance of 8.32 km without a wajanbolic antenna. A poor RSSI value can cause an error. The results obtained from the experiments in the study showed that the implementation of Raspberry Pi-based IoT Gateways in the LoRa communication system on flood detection worked well.

Abstract

Damage to the 20 kV cubicle at PLN Branch Lahat often occurs because the overheater causes considerable losses. Insulation failure at the corroded cubicle terminal results in a decrease in heat production and heater resistance. So there is a mall function (saturated) and a short circuit. Therefore, this study aims to design a prototype to maintain temperature and humidity conditions in a 20 kV cell using Proportional Integral Derivatives (PID) and LabVIEW. Set the Kp, Kd, and Ki parameters, namely proportional, derivative, and integral constants, so that the desired temperature can be maintained to prevent corrosion. The parameter value was obtained at the set point of 40 °C by a value of Kp is 1, Ki is 0.1, and Kd is 0.05, resulting in a rise time of 188 s, a peak time of 216 s, stabilization of 288 s, and a steady-state error of 0.30%. In addition, the setpoint is 43°C, the rise time is 272 s, the peak time is 311 s, the settling time is 377 s, and the steady-state error is 0.60%. Moreover, the 45°C setpoint has a rise time of 338 s, a peak time of 380 s, a settling time of 448 s, and a steady-state error of 0.93%. These results indicate a reasonably good prototype performance.
