Abstract

Penyangraian merupakan salah satu tahap terpenting dalam pembuatan bubuk cokelat, selain mengurangi kadar asam dan kadar air. Sistem kendali suhu pada proses penyangraian dikendalikan oleh pengendali PID yang akan mengatur bukaan motorized valve yang mempengaruhi suhu sirkulasi tabung. Kendali PID dituning menggunakan kombinasi metode Ziegler[1]Nichols dan metode trial and error untuk mendapatkan respon sistem yang lebih baik. Suhu penyangraian berhasil dikendalikan menggunakan pengendali PID dengan nilai parameter Kp = 2.7, Ti = 0.035, dan Td =0. Respon menghasilkan kinerja dengan overshoot 5% dan settling time 12 menit untuk mencapai suhu penyangraian 300℃.

Abstract

The gravity capsule served as the main object of focus in a community service activity aimed at introducing science to children in the Cibogo Bandung shelter, specifically targeting first and second-grade elementary school students. The service learning method was employed to ensure the learning process remained simple and accessible, considering the young age of the participants. A basic experiment using the gravity capsule was conducted to introduce fundamental science concepts such as gravity, energy, and momentum. The outcome of this community service activity was considered successful, with a comprehension rate of 78.5%, based on responses to questions covering the materials delivered. However, improvements are still needed to enhance content retention among participants. Additionally, requests from the partner community for the program to be conducted regularly form the foundation for the sustainability of this initiative.

Abstract

The wind energy adventure with children from the shelter home has become the focus of a community service initiative aimed at elementary school children in the Cibogo area. The need for alternative forms of learning to stimulate interest and engagement among children at the shelter inspired the application of science using a wind power car as the central theme of this community service program. The activity was conducted using an experimental method, training the children to observe, design tools, measure results, and draw conclusions from the objects they created—ranging from mechanical components to the drive system—through hands-on experimentation. The outcomes of this wind energy adventure had a positive impact on the children, the service team, and the surrounding community, fostering awareness of the importance of experiment-based education and providing valuable knowledge to all participants involved.

Abstract

This study aims to design and build a Sign Language Interpreter Device with Voice Output in the form of an ATMega328 Microcontroller-Based Voice Speaker Module so that in its implementation and later in designing this device the writer focuses on the translation of 16 words that have been predetermined in Indonesian Sign Language especially in Denpasar City by using a Flex Sensor and a Gyro Sensor based on the ATMega328 Microcontroller with Arduino IDE programming. This device is also equipped with a 4GB SD card memory for storing voice recordings, using an ATMega328 microcontroller, four analog Flex sensors, a Gyro sensor, a buzzer and an 8 ohm speaker, and using a 7.4 volt Li-Po battery. The application of this device is aimed for thehearing impaired people who fall into the adult category who can understand writing and understand sign language. The output of this device uses an MP3 player module that is already included in the Sign Language Interpreter Device. The flex sensor readings range from 998-1005 ADC (analog digital converter) in open conditions and the sensor ranges from 1006-10018 ADC in closed conditions. The reading for the gyro pitch (Y axis) ranges from -10º to 76º then on the reading of the gyro Roll (X axis) ranges from -100º to 90º. Keywords: ATMega328 microcontroller; Buzzer; Flex Sensor; Gyro Sensor

Abstract

During the pandemic of Corona Virus Disease 2019 (COVID-19) that hit Indonesia, all activities were very limited. Electrical Engineering Study Program of Universitas Kristen Maranatha was motivated  to share knowledge especially in the field of science about "Basic Unity and Virtual Reality (VR)" to the public. This has been realized through community service activities pursued by students and lecturers. VR refers to computer simulations that create images of the world that appear in human senses, in the same way as humans perceive the real world in reality. This community service used the Participatory Action Research (PAR) approach. From the results of a survey of community service activities that have been carried out, it is concluded that the success in providing mentoring to improve the ability of the community to use Basic Unity and VR online, is shown by the results of an increase in the score from an average of 5.85 before the activity, to 7.58 (from a total score of 10) after the activity. The community service committee team's service during the activity was also considered very good and worthy of being maintained in subsequent activities. Meanwhile, the implementation of providing teaching materials, the readiness of the trainers, and the implementation of organizing activities online, still need to be re-evaluated and improved in the future for better results.

Abstract

The COVID-19 pandemic has greatly affected the learning process in practice, especially for people in the engineering field. Activities stopped and learning activities become very obstructed for a long time. Tinkercad is a simulator application that could be used as a learning tool or medium in engineering. The service learning method is used as a way of teaching and learning that links positive and meaningful action in society. Service learning uses demonstrations and experiments are used to transfer knowledge to society. A workshop elaborating the use of Tinkercad based on the service learning method was carried out online through community service activities to meet community needs in the engineering field. The workshop results showed that the service learning method was sufficient to help the community to meet the learning needs of engineering practices. A thorough demonstrations by instructors and experiments done by participants guided by assistants, produced a satisfactory result for more than 90% of the workshop participants. Periodic literacy provision was a follow-up to improve the abilities of all participants who have take part in workshop activities.
