Abstract

Communication technology continues to develop rapidly, now 4G has become a network standard used in various countries. 4G networks offer higher data speeds, lower latency, and greater capacity compared to previous networks. Now, we can exchange information and establish relationships with others without having to meet in person. However, in remote areas and areas with limited networks, there are still problems in using these celluler phones that are poorly understood by people living in remote areas or areas that are not covered by celluler phone networks. For example, the use of very simple cellular phone facilities such as Short Message Service (SMS). OpenBTS is a new part of BTS technology that is very economical both in terms of funds and resources because openBTS is based on opensource software so that it is easily available and anyone can implement this openBTS, and can provide services to communicate such as Short Message Service (SMS) or short messages and can be used as a substitute for telephone facilities in the event of signal interference. For this reason, in this study, the implementation of services for short messages using the Universal Software Radio Peripheral (USRP) B210 device on 4G-based 3GPP communication standards. The hardware used is USRP B210.

Abstract

Hearing impairment was considered a significant barrier to understanding verbal communication. Therefore, an alternative communication medium in the form of sign language was required to bridge interactions between Deaf and hearing individuals. One of the sign languages used in Indonesia was the Indonesian Sign Language (BISINDO). The advancement of deep learning technology provided a great opportunity to develop an effective and accurate BISINDO alphabet classification system. This research was conducted to evaluate and compare the performance of two Convolutional Neural Network (CNN) architectures, namely ResNet50 and MobileNetV2, in classifying BISINDO alphabet images consisting of 26 classes from A to Z. Model training wa carried out over 100 epochs and was analyzed using metrics such as training and validation accuracy, precision, recall, F1-score, and confusion matrix. The training process used a dataset that was divided into 80% training data and 20% validation data, and include image preprocessing steps such as resizing and rescaling. The evaluation results showed that ResNet50 achieved 86.42% training accuracy and 98.64% validation accuracy with 98.80% precision, 98.69% recall, 98.57% F1-score, and 31 misclassifications. In contrast, MobileNetV2 showed superior performance with 99.99% training accuracy, 99.65% validation accuracy, 99.69% precision, 99.65% recall, 99.61% F1-score, and only 8 misclassifications. Based on these results, MobileNetV2 was recommended as a more effective and efficient architecture for BISINDO alphabet image classification compared to ResNet50.

Abstract

The teacher's job is to increase student interest in learning with the aim of improving student achievement in the learning process. One of the problems faced by teachers at SMAS Kristen Soleman is the lack of knowledge and skills in the use of animation learning technology, so that the teaching materials produced are less attractive and become one of the factors in decreasing student interest in the learning process. The purpose of this community service is to improve knowledge and skills through training and mentoring in making interactive teaching materials using animated learning technologies such as Canva, Kahoot, and Powtoon to teachers at SMAS Kristen Soleman. The implementation method is carried out starting from the preparation stage (field observation, literature study, and partner identification), the implementation stage (training and mentoring), to the evaluation stage using pre-test and post-test before and after training and mentoring is carried out. Based on the evaluation results of training and mentoring teachers in making interactive teaching materials using animated learning technology, it shows an increase in knowledge from 41.7% to 100%, where teachers already knew interactive teaching materials using animation learning technology. Meanwhile, teachers' skills increased from 12.5% to 91.7%.

Abstract

Digitalisasi peminjaman alat dan ruangan di Laboratorium Teknik Telekomunikasi Politeknik Negeri Sriwijaya bertujuan meningkatkan efisiensi, mempercepat administrasi, dan mendukung sistem paperless. Sistem berbasis web ini dikembangkan dengan PHP dan MySQL serta diuji menggunakan XAMPP. Hasilnya, proses peminjaman menjadi lebih cepat, akurat, dan terdokumentasi dengan baik melalui fitur login, form peminjaman, validasi data, pemantauan status, dan laporan. Digitalisasi ini berhasil mengurangi kesalahan, meningkatkan transparansi, dan mempercepat pengambilan keputusan. Selain itu, kegiatan ini dilakukan dengan metode sosialisasi kemudian dilanjutkan dengan uji coba website oleh mahasiswa, Tenaga Kependidikan dan Dosen selaku user. Hasil uji coba website menunjukkan bahwa sistem yang dibuat layak digunakan dan diharapkan dapat membantu dalam pengelolaan alat dan peminjaman ruangan pada Laboratorium Teknik Telekomunikasi agar lebih efisien. Berdasarkan hasil kuesioner nilai rata-rata uji kelayakan sistem sebesar 86,1% sangat layak.
