Abstract

In some universities, student advisors are often hired to enhance students’ retention rate. Having some students in mind, these advisors may find some difficulties in guiding the students in terms of selecting relevant courses. This paper proposes an advisor-oriented course recommendation system. Using this system, the advisors may suggest relevant courses to their students easier and more accurate. This system relies on student grades and comprehensive course data. Further, it utilises content-based and collaborative filtering for predicting relevant courses. According to our evaluation, the system is considerably effective; the accuracy of content-based filtering is about 66% while the accuracy of collaborative filtering is about 58%. Further, some parameters may be potential for enhancing accuracy while the others may be not.

Abstract

Caring for indoor ornamental plants is a challenge for the owner. They require special attention and treatment from the owner to grow well and beautifully. The most important and common thing that must be considered is choosing the type of plant that can adjust to the atmosphere and conditions in the room. Some indicators that determine the typical environmental conditions of potted ornamental plants are air temperature and humidity, light, and soil moisture. The smart plant pot robot is designed to provide smart care for indoor ornamental plants by incorporating a line follower mechanism. Equipped with functionalities like plant watering and environmental monitoring (including light, temperature, and humidity levels), this robot offers comprehensive plant care. Users can conveniently monitor these parameters via a smartphone using the Blynk application. In its design, the robot integrates various components such as temperature and humidity sensors, light intensity sensors, photodiode sensors, ultrasonic sensors, voltage sensors, Arduino Uno, relays, water pumps, RTC, ESP8266, DC motors, and motor drivers. The primary goal is to create a system capable of monitoring plant conditions and providing watering assistance, utilizing line tracking for transporting potted plants to sunlight exposure spots. This system aims to offer practical benefits to the community, especially in optimizing indoor ornamental plant care. The test results of this system, utilizing Arduino Uno as the microcontroller and ESP8266 for WiFi communication with the Blynk application, along with various sensors as input devices, demonstrate a remarkable 100% success rate. Notably, this accuracy is based on functional testing, encompassing everything from the robot's path detection to its connectivity with the Blynk application.

Abstract

Tantrums are outbursts of anger and they can occur at any age. An attitude tantrum or what is commonly referred to as a temper tantrum is a child's outburst of anger that often occurs when a child shows negative behavior. Emotional outbursts of tantrums that occur in children with autism are not only to seek the attention of adults, but also as an outlet for a child's feelings for parents and those around him on a whim or feeling he is feeling, but the child cannot convey it. For this reason, researchers propose a system for detecting early symptoms of tantrums in children with autism through facial expressions with CNN. The CNN method is one of the deep learning methods that can be used to recognize and classify an object in a digital image. Then the preprocessing process is carried out using labeling on the data. Then the CNN architecture is designed with input containing 48x48x1 neurons. The data was then trained using 357 epochs with an accuracy rate of 72.67%%. Then tested using test data for children with autism to get an average accuracy value of 72.67%%.

Abstract

This paper presents the design and implementation of an automatic ceiling fan speed regulator using web camera and a temperature sensor. Fans have become a very important aspect of our daily lives to present us with comfort especially in hot climates. However, they come with some attendant issues such as a person having to move to where the fan regulators are placed to be able to adjust the speed of the fan. This can be difficult as temperatures change during the day as well as at night when one is asleep. This also poses a problem for physically challenged individuals with mobility difficulties. This project seeks to design a solution that involves automatic fan regulation. This was achieved using a temperature sensor, a camera that captures images, and a system intelligent unit that processes the captured images to detect occupancy. The speed of the fan is then automatically adjusted based on the room temperature and occupancy. The system was implemented on a raspberry pi, a resource constrained edge computing environment.

Abstract

Javanese script is a part of Javanese culture which is owned by Javanese society which should be preserved. One of the efforts to preserve it is by introducing Javanese script in formal education. Javanese language subjects are local content that must be taken by students from grade I to grade VI elementary school students. Javanese script began to be introduced to third grade elementary school students. Javanese script is one of the basic competencies that most students do not understand because most students consider Javanese script a difficult material to learn because of its various forms and complicated writing rules. Therefore, to overcome the above problems, a learning innovation using augmented reality technology is needed. With this application, it is hoped that students can be helped in understanding Javanese script material. Java script learning applications are made using the Waterfall method with the development of augmented reality, namely marker based tracking. The output of this application is that the application will display a video on the smartphone screen that contains learning material for Javanese script. In the black box test results on functional testing obtained a percentage of 99.7%, camera distance testing obtained 66.25% results, camera angle testing obtained 75% results, light intensity testing obtained 100% results. In the usability test results, the Carakan application obtained an adjective rating of 71.54 in the Good category, obtained a grade scale result in the C category, and obtained acceptability ranges in the acceptable category.

Abstract

The increase in motorcycle theft cases has become a serious concern. This research aims to design a motorcycle parking security system through a website in response to this challenge. The system uses a website accessible via smartphones using QR code. Users scan the provided QR code to access the website, where they will be prompted to enter a password that functions as a controller for the locking and unlocking process of the motorcycle's front wheel using a servo motor. Furthermore, to detect forced removal attempts, the system is equipped with an alarm that notifies the parking attendant. This alarm will be activated if vibrations above 20 cm/s2 are detected and will be accompanied by a buzzer sound as a danger signal. Based on the results of the study, this system can work well and produce the appropriate output as previously designed with a success percentage of 91% and the servo motor as a motorcycle safety device can work to lock the front tire of a motorcycle that has a tire tread width of 90 mm according to with what was previously defined

Abstract

The problem of time discipline in the work environment is a common challenge that is often faced, especially in organizations with many employees. This problem becomes increasingly complicated when the organization has many employees with different work schedules and is spread across prominent locations. A time discipline monitoring system has been developed to overcome this problem. This system is designed to make monitoring employee attendance and time discipline easier by utilizing fingerprint scanner technology near the entrance to a room or office building. When an employee enters or leaves, they are required to scan their fingerprints using the fingerprint scanner. The data from the fingerprint scan is then recorded and stored on a server connected to the system. The administrator can easily access this data via a website provided by the system. This way, monitoring employee time discipline becomes more efficient. Furthermore, this system also has a feature that allows the head of organization to permit employees to have tasks outside the office. This simplifies the process of managing tasks outside the office and increases work flexibility. Based on the test results, the system demonstrates strong performance in monitoring, achieving a fingerprint detection accuracy of 95% and achieving a 100% success rate in website monitoring

Abstract

Lora is the solution to the problem of the need for long-distance two-way communication between machines that are targeted by IoT (Internet of Thins. LoRa has long-distance transmission capabilities, has power, and a low bit rate. Based on the needs related to LoRa, further research is needed, to analyze the performance of LoRa communication. The LoRa communication protocol will be applied to the One Duit Bogor bridge monitoring system using the Website and LabVIEW. This study used LoRa SX1276 with a frequency of 915MHz with the LoRa point-to-point method and LoRa gateway. The parameters analyzed include RSSI (Received Signal Strength Indicator), SNR (Signal to Noise Ratio), Delay, Throughput, and Packet loss to determine the quality of LoRa performance with TIPHON standards. Based on the tests that have been carried out, it proves that LoRa communication has good performance. In urban areas or around the Satu Duit Bogor bridge, LoRa can transmit data from a distance of 0 to 500 m with an average delay of 217 ms, an average packet loss of 10.237%, an average throughput of 137.881 bps, an average SNR of 7.54 dB, and an average RSSI of -71,798 dBm. At a distance of 0-400 m there is an insignificant change in LoRa parameters, but at a distance of 500 m a high change occurs, this is due to the fact that the distance greatly affects the transmission of data. The longer the range, the more obstacles will be passed so that data transmission is disrupted.
