The Design of IoT Based Lighting Installation Tools in Electrical Installation Engineering and Microcontroller Systems Courses

Internet of Things (IOT)-based lighting installation development Since teaching aids are an exact science, it is essential to have a tool that can depict the subject covered in the Electrical Installation Engineering course. The teaching tools created are meant to help lecturers better present the topic for electrical installation engineering to their students while also making it simpler for them to comprehend. In order to turn on and off lights and outlets using a smartphone and a manual switch in the event that the wifi network is damaged, this study added Internet of Things (IOT) installation procedures and a swap switch. The Research & Development approach is being used in this investigation. A validation sheet is created by planning and creating research instruments, which is what is done to test the viability of instructional aids by professional validators. According to the results of expert validation, this teaching tool is appropriate for use with media and material experts based on the percentage values of media expert 1 receiving a score of 94.28% and media expert 2 receiving a score of 97.14%, and for material expert 1 receiving a score of 90% and material expert 2 receiving a score of 92%, with the category "Very Eligible".


Introduction
Every human being must keep up with the advancement of technology in order to avoid falling behind.One such example is the internet of things (IoT), which fosters the growth of technology that is crucial to modern human existence.It is highly recommended to apply and teach the internet of things (IoT) to the next generation through the application of IOT teaching aids in schools or colleges in order to develop the capabilities that they have.One such application is making a lighting installation teaching aid that has been designed or supported by technology and controlled via a smartphone in the classroom.Therefore, it is crucial to have teaching tools that facilitate collaboration between specific lecturers and students in order to achieve an emphasis on understanding the material in order to achieve the continuity of the learning cycle in Electrical Installation Engineering and microcontroller systems.
The findings of online questionnaires administered by the researchers' Google Form revealed that many Electrical Engineering Education students who had taken the Electrical Installation Engineering course believed that it was crucial to have teaching aids in this subject.The average justification for this belief was that the material is difficult to comprehend.Regarding some earlier studies on electric lighting fixtures or domestic electrical installation components.A research of " Building information modeling for sustainable design and LEED® rating analysis," by [1], was created as the final project for the Mechatronics Department at the Polytechnic of Malang City.By including an exchange switch that allows one light to be turned off from another location, this teaching tool illustrates the installation of a complete electrical installation.A research of " Design and Fabrication of Smart Home With Internet of Things Enabled Automation System," by [1] designed to finish the department of industrial engineering's final project.This tool is designed to accelerate technological advancement in the area of installing lighting in homes.Which is where a smartphone may be used to turn on and off lights and electronic devices at home.The findings of [2] study, "Miniature electrical installations to increase student understanding," indicate that the two classes, namely classes without media and classes with media, have different average values.that the inclusion of tiny media improves students' comprehension.
The research will differ from other studies in that it won't just simulate a lighting installation powered by the Internet of Things (IoT), where a number of instructional aids may be managed via a smartphone.However, the researchers also incorporated an exchange switch into a number of lighting fixtures in this investigation.To solve the issue of a downed WIFI network, an exchange switch was built, rendering a number of lighting installations, such as lights and outlets, inaccessible to smartphone control.The lights and sockets can now be manually turned on and off thanks to an exchange switch.The final section of this study focused on "Design of Internet of Things (IoT)-Based Lighting Installation Tools in Electrical Installation Engineering and Microcontroller Systems Courses" [3].Designing and implementing an Internet of Things (IoT)-based lighting installation toolkit can speed up learning, enhance the effectiveness of

Methodology
Research-Based Development (R&D) or research-based development, which refers to research techniques used to create certain goods and evaluate their efficacy, is the research paradigm employed in this study.[4] provides a systematic overview of the processes the researcher used to ensure that the product he produced meets an eligibility requirement in the development model.Because the research was only intended to examine the viability of an Internet of Things-based lighting installation teaching tool in the Electrical Installation Engineering course, it was only used up until the product validation stage.
The absence of internet of things (IoT)-based teaching resources in the Electrical Installation Engineering course is the possible issue that is examined in the first step [5].The first step taken to get information and data is to post a link to a google form questionnaire filled out by Electrical Engineering Education level 18 who have taken electrical installation engineering courses.The second stage collects data from observations and literature studies.Information gathered from observations about the need for teaching tools in current electrical installation engineering courses.92.9% (13 people) of those who participated in the observation said it was crucial to have teaching aids for this subject because, on average, it was difficult to understand because it was just theory and an overview of electrical installation circuits; however, if there were props, it would be simpler for us to understand; only 7.1% (1 person) said it was not crucial.Then look for reading materials pertaining to the issue at hand, such as library books, articles, websites, and others, assisted by consulting programmers.The final stage is designing, which combines the circuits for each block to create the instructional aids as a whole.The ESP8266 functions as the Arduino Uno's control center, processing incoming data and generating output commands.The Blynk application is unable to instruct the relay to turn lights or sockets on or off if there is a WiFi network interruption due to the use of an exchange switch [6].Because the exchange switch's operating system is identical to the relay's, which has 1 input and 2 outputs, it may be projected onto the relay as shown in Figures 1 and 2. This design requires the usage of an exchange switch.The on/off lights that have been designed are controlled via the Android app BLINK.To connect to the Arduino program, we first create a mydevice project in the blynk application [7].After that, we create three ON/OFF buttons to control the lights on the props, as seen in figure 4.    Regarding the expert validation sheet, it was used to determine whether instructional aides were media and material-compatible.
Researchers conduct prop presentations before material experts and media experts while handing out validation sheets to each expert as a tool for feasibility testing in terms of material and media teaching aids for lighting installations based on the Internet of Things (IoT).This is done in order to analyze expert validation data collection techniques.In order to determine the validity of a teaching aid from the responses of respondents, the total score of the answers obtained divided by the total score of the maximum answers set will be used in a descriptive analysis of the respondents' answers to determine the feasibility of the props.Based on the percentage level of responses in table 2, the categories of expert validation results were determined.

Result and Discussion
After conducting study, the researchers created a lighting installation tool based on the internet of things (IoT), which combines the circuits previously outlined.This created teaching tool can be used in microcontroller system courses, specifically in the topic "input and output," and electrical installation engineering courses, namely in the material "electrical installation design," as shown in Figure 6.Media experts' endorsement of instructional tools in the media On November 12, 2021, face-to-face 1 was completed.media experts' endorsement of instructional tools in the media On November 15, 2021, face-to-face 2 was completed.As shown in table 5. Recap The results of the media expert validation based on table 5 show the total score obtained is 65, with a maximum total score of 70 obtaining an eligibility percentage of 95.71%, the media expert's validation of the eligibility of teaching aids in terms of media is also in the "very feasible" category.Then, two material experts whose aim is to obtain information, criticism, and advice from experts or validators regarding the internet of things (IoT)-based lighting installation engineering material that meets the feasibility test in terms of material and can be developed into quality teaching aids in terms of material.Two Material validation expert of lecturer Muhammad Rizal Facri, S.T, M.T and Raihan Islamadina, M.T., has tested the props on November 9 2021.Table 6 displays the findings of the validation test conducted by Material Experts 1 and 2. Table 6 summarizes the results of the material experts' validation, which yielded a feasibility percentage of 91% and a total score of 91 out of a possible 100.The media expert's validation of the eligibility of teaching aids in terms of media also fell under the "Very Eligible" category.In this investigation, the researchers ran an experiment with two stages, the first of which involved 10 trials of utilizing the Blynk application to manage the lighting system.The second test uses exchange switches with 10 trials to control lighting fixtures like lamps.This experiment's goal is to determine how long it takes to turn on and off lights when utilizing the Blynk app and the exchange switch, as shown in table 7.After testing 10 times of controlling using Blynk and an exchange switch, the longest time to turn on the lights using the blynk application controller is 2 seconds, the fastest time is 0.1 seconds, and the average time needed is 0.4 seconds.Meanwhile, if controlling the lights using an exchange switch, the average is only 0.1 seconds.This study aims to design and develop an internet of things (IoT) based lighting installation aid using the Research and Development (R&D) research model.In addition, this research also aims to develop valid and practical internet of things (IoT)-based teaching aids.The data obtained from the expert validation results shows the percentage of eligibility of teaching aids in terms of material and media.The results of media validation by media expert 1 obtained a value of 94.28% and media expert 2 obtained a value of 97.14%, with the final results of the validation of the two media expert validators obtaining a value of 95.72, while the results of material validation by material expert 1 obtained a value 90% and material experts 2 get a score of 92%, with the final validation results of the two media expert validators getting a score of 91%.According to [8], the author of the book "quantitative research approach" categorizes the eligibility of props ranging from 0% -20% in the "Very Ineligible" category, 20% -40% "Not feasible", 40% -60% "Neutral", 60% -80% "Fair", 80% -100 % "Very Eligible".In terms of material and media the feasibility of the Internet of Things (IoT)-based Lighting Installation Toolkit is "Very Feasible.From the results of the expert validation of the feasibility of teaching aids, it was explained that in terms of the media, the teaching aids were also in accordance with the literature review of teaching aids, especially the characteristics of teaching aids in terms of teaching aids material, in accordance with the literature review starting from the technique of installing electrical installations.
Employing the blynk application controller and exchange switches to test internet of things (IoT)-based lighting installation products.Blynk, according to [9], is a brandnew platform for creating user interfaces for managing and keeping an eye on hardware projects from iOS and Android mobile devices.Because using the blynk application is so reliant on an internet connection, the results of tests using the blynk application control show that the delay time varies.For best results, utilize a fast, reliable internet connection.Alternatively, if the internet connection is erratic, there will be a delay in the lights going on, and you might not be able to control the lights using the Blynk application if the internet network does not permit it.While using an exchange switch, you merely physically detach and reconnect the electricity, therefore there are no barriers or delays.
It is important that if the internet connection is lost, you can manually turn on and off the lights using a swap switch.This is why designing teaching aids based on the internet of things (IoT) and projecting exchange switches on the circuit makes the circuit more complete than previous research.Depending on the state of the internet connection speed, different delays are tested when turning on and off the lights.The direct current is linked manually, thus if you use an exchange switch to manually turn on and off the lights, you may claim that it won't be impacted by an internet connection.
Four expert lecturers separated the validation testing into two parts: media validation by two expert validators, and material validation by two expert validators.The final validation results of the two media expert validators obtained a value of 95.71.In contrast, the results of the material validation by expert material 1 obtained a value of 90% and expert material 2 obtained a score of 92%, with the final validation results of the two media expert validators obtaining a value of 91%.Therefore, Internet of Things (IoT)-based Lighting Installation Tools are "Very Feasible" in terms of material and media practicality.The researcher advises adopting internet of things (IoT)-based lighting installations once the research is complete and the viability of the IoT-based lighting installation concept has been tested.Utilizing a quick and reliable internet connection to get the best results, followed by testing this teaching tool on students enrolled in the Electrical Installation Engineering course to determine whether it aids students in understanding the course material.
