Abstract

The COVID-19 pandemic has had a major impact on the education sector, including universities, which must immediately switch from classical learning to online learning. In the Electrical Engineering study program at Sebelas Maret University, one of the main challenges is achieving the learning output targets set in the courses, especially in the Autonomous Vehicles course. This study aims to examine the implementation of the Project-Based Learning (PBL) approach in the Autonomous Vehicles course during the pandemic, as well as to understand students' perceptions of the learning methods applied, including through online learning with blended learning. The study used a case study approach, where students were divided into three groups to work on an autonomous vehicle simulation project using Webots software. Each group faced different challenges, such as avoiding obstacles, overtaking other vehicles, and self-parking. A questionnaire was used to collect data on students' perceptions of the implementation of PBL. The results showed that PBL was successfully implemented well in the Autonomous Vehicles course, although there were several challenges, especially related to the duration of the project. Overall, students felt that this method was effective in improving their technical and soft skills, such as critical thinking, problem solving, and teamwork.

Abstract

This literature review comprehensively explains the role of sentiment analysis as a policymaking solution in companies, organizations, and individuals. The issue at hand is how sentiment analysis can be effectively applied in decision making. The solution is to integrate sentiment analysis with the latest NLP trends. The contribution of this research is the assessment of 100-200 recent studies in the period 2020-2024 with a sample of more than 5,000 data, as well as the impact of the resulting policy recommendations. The methods used include evaluation of techniques such as Deep Learning, lexicon-based, and Machine Learning, using evaluation matrices such as F1-score, precision, recall, and accuracy. The results showed that Deep Learning techniques achieved an average accuracy of 93.04%, followed by lexicon-based approaches with 88.3% accuracy and Machine Learning with 83.58% accuracy. The findings also highlight the importance of data privacy and algorithmic bias in supporting more responsive and data-driven policymaking. In conclusion, sentiment analysis is reliable in areas such as e-commerce, healthcare, education, and social media for policy-making recommendations. However, special attention should be paid to challenges such as language differences, data bias, and context ambiguity which can be addressed with models such as mBERT, model auditing, and proper tokenization.

Abstract

An induction motor (IM) is one type of AC motor which widely used. IM is chosen due to its simplicity, reliability, efficiency, and low cost. There are many methods proposed to control the speed of IM which is known as variable speed drive (VFD). In this study, the DTC method is used since it is more robust to the parameter’s changes. The combination of the Fuzzy and PI method is used in speed control. PID performances decrease when the system condition changes. Therefore, fuzzy is used as an adaptive algorithm to vary the PID gain. It was superior in terms of settling time, overshoot/ undershoot, and IAE compared to the PI method. It has lower IAE in both speed tracking and loaded conditions by 44.98% and 4.47%, respectively.

Abstract

Kepyar Village, located in Purwantoro District, Wonogiri Regency, possesses significant potential for the development of natural tourism due to its lush and pristine environment. However, despite its scenic beauty, the village remains relatively underpromoted, resulting in limited tourist visits, predominantly from nearby areas. This study explores the use of TikTok as a promotional tool to enhance the visibility of Kepyar Village as a tourist destination. By utilizing TikTok for destination branding, the village aims to attract a wider audience, thereby benefiting the local economy and community. The initiative is expected to raise broader public awareness about Kepyar Village’s tourism potential, contributing not only to its reputation as a tourist village but also providing an economic avenue for residents to improve their livelihoods.

Abstract

The rapid advancement of technology is driving the transition toward Society 5.0, where intelligent transportation systems enhance safety, efficiency, and sustainability. One of the biggest challenges in transportation is the high frequency of vehicle accidents, with approximately 80% attributed to driver error. To mitigate this, Advanced Driver Assistance Systems (ADAS) have been developed to improve vehicle autonomy and reduce accidents. This research proposes a potential field-based collision avoidance system for autonomous vehicle navigation, where the vehicle and obstacles act as positive poles, repelling each other, while the target destination serves as a negative pole, attracting the vehicle. Experimental results demonstrate a GPS positioning error of 1.55 m with a 66% success rate and LiDAR sensor accuracy of 96.4%, exceeding the required 95% threshold. Obstacle avoidance was tested with two safety thresholds (2 m and 2.5 m) across single- and two-obstacle scenarios. The 2 m threshold resulted in shorter travel distances (16.406 m vs. 16.535 m for 2.5 m) and faster completion times (19.036 s vs. 19.144 s), while the 2.5 m threshold provided greater clearance. GPS accuracy was significantly influenced by HDOP values and satellite count, with lower HDOP improving trajectory precision. The system successfully adjusted its trajectory in response to obstacles, ensuring effective real-time navigation.

Abstract

The capacity strengthening program for electric vehicle conversion workshops at SMK Karya Nugraha Boyolali was implemented through a synergistic collaboration model between universities, vocational schools, and industry. This study employed a qualitative descriptive approach with a case study method to evaluate the effectiveness of the six-month program. The findings revealed a significant improvement in participants’ technical competencies, as evidenced by the increase in pre-test and post-test scores, as well as the successful development of a solar photovoltaic (PV)-based electric vehicle charging station prototype. Beyond technical achievements, the program also strengthened multi-stakeholder collaboration and fostered the creation of a micro-scale clean energy ecosystem within the school environment. These results demonstrate that practice-based vocational training combined with strategic collaboration can make a substantial contribution to achieving the Sustainable Development Goals (SDGs), particularly clean energy (SDG 7), industry innovation (SDG 9), and climate change mitigation (SDG 13).

Abstract

Saat ini listrik menjadi kebutuhan utama masyarakat. Pembangkit listrik di Indonesia sebagain besar bersumber dari energi batu bara yakni mencapai 57.2%. Batu bara sendiri merupakan sumber energi yang tidak bisa diperbaruhi. Selain itu, pembangkit listrik jenis ini menimbulkan pencemaran udara. Untuk itu, sumber pembangkit listrik alternatif yang ramah lingkungan dan dengan suplay yang melimpah sangat diperlukan. Salah satu sumber listrik alternatif yang paling mudah untuk dibangun dengan biaya rendah adalah sistem panel surya. Sistem panel surya sudah banyak diaplikasikan di Indonesia, bahkan sudah dibangun Pembangkit Listrik Tenaga Surya (PLTS). Beberapa tempat yang sudah terpasang sistem panel surya, pada akhirnya terbengkalai karena rusak dan masyarakat belum begitu faham sistem panel surya sehingga tidak bisa memperbaikinya. Untuk itu, sosialisasi tentang energi terbarukan ini penting untuk dilaksanakan. Pengenalan sumber energi terbarukan tenaga surya ini perlu dikenalkan lebih dini kepada siswa sekolah untuk meningkatkan minat dan rasa ingin tahu siswa dalam mempelajari, memanfaatkan, dan bahkan mengembangkan nantinya. Kegiatan dilakukan secara daring guna mematuhi protokol kesehatan covid-19. Media yang dipakai adalah grup whatsapp, video, dan e-booklet. Untuk mengukur keberhasilan program, sebelum acara dilakukan pre-test dengan hasil 22, 5% siswa tidak tahu tentang panel surya. Setalah sosialisasi post-test, hasilnya rata-rata nilai mencapai 79,46%, yang menunjukkan tingkat pamahaman peserta cukup baik terhadap materi yang disampaikan. Sampel pertanyaan mendasar tentang sistem panel surya, menunjukkan hanya 0,9% siswa yang salah. Kesimpulan akhir, siswa telah mendapat pengetahuan tentang energi terbarukan panel surya melalui kegiatan sosialisasi yang telah dilakukan.
