Abstract

Volcanic eruptions are natural events that have the potential for significant damage to humans and the environment. Identifying the type of volcano earthquake is key in disaster risk mitigation by providing information on the process and the location of magma activity beneath the volcano. In this research, we propose an approach using Principal Component Analysis (PCA) to identify types of volcanic earthquakes based on seismic recording data. Identification begins by reducing feature dimensions using Principal Component Analysis (PCA). The PCA results were then clustered and then evaluated Silhoutte Score, ARI, CH-Indeks, DB-Indeks. Experiments were carried out using recorded data totaling 329 samples. For each recording, feature extraction was carried out in the form of statistical features, entropy features and shape features with a total of 16 features in the time and frequency domains. PCA results on the two main components PC1 explained 49.2741% and PC2 24.5507% of the data variance and evaluation results using Silhouette Score were equal to 0.53, ARI 0.8, CH-Index 529.34, and DB- Index 0.6

Abstract

The advent of the Industrial Revolution 5.0 has had a profound impact on the global landscape, including Indonesia. Micro, Small, and Medium Enterprises (MSMEs) play a significant role in the national economy, but a considerable number of them have yet to leverage e-marketplaces and social media as marketing tools. This has resulted in a digital chasm between MSMEs and larger corporations. Thus, it is imperative to provide adequate assistance and training to MSMEs to enable them to harness digital technology and enhance their competitiveness in the e-commerce market. The Participatory Action Research (PAR) method is employed, which involves training, account creation practice, and mentoring for MSMEs. The training is conducted in three phases, namely preparation, implementation, and evaluation. As a result of community service activities, MSMEs need to innovate their products and employ digital marketing strategies through platforms such as marketplaces and social media. Diligent preparation is essential to enable MSMEs to adapt to these changes and bridge the digital divide. Community service initiatives in Kedondong Village strive to encourage MSMEs to embrace marketing strategies through social media and e-commerce platforms as a means to increase revenue and expand businesses in the fiercely competitive digital era.

Abstract

In the 5.0 era, Islamic religious instruction in higher education is crucial as in forming students' morality and character. With a correct and deep understanding of religion, students can internalize these values in their daily lives and make good and responsible decisions. The article's aim is to give an outline of the Islamic religious teaching and learning processes in public colleges as of 5.0. A qualitative research methodology was adopted, and instructors and students were interviewed as well as observed to obtain data involved in the learning and teaching process of Islam in public universities. Then, content analysis is used to assess the acquired data utilizing qualitative data analysis techniques. The findings indicated that there is still room for improvement in the standard of Islamic religious instruction in public universities, especially in terms of subpar teaching and learning. Lack of emphasis on character education, poor teaching, and minimal use of technological in the process of learning and instruction are some of the reasons that contribute to the poor quality of Islamic religious education in public universities. Thus, character education, raising the bar of instruction, and implementing better technology in the learning and teaching process of Islam in the 5.0 era are necessary to improve the quality of Islamic religious instruction in public universities. (Di era 5.0, pengajaran agama Islam di perguruan tinggi menjadi sangat penting dalam membentuk moralitas dan karakter mahasiswa. Dengan pemahaman agama yang benar dan mendalam, mahasiswa dapat menginternalisasi nilai-nilai tersebut dalam kehidupan sehari-hari dan mengambil keputusan yang baik dan bertanggung jawab. Artikel ini bertujuan untuk memberikan gambaran umum tentang proses pengajaran dan pembelajaran agama Islam di perguruan tinggi umum di era 5.0. Metodologi penelitian kualitatif diadopsi, dan para pengajar serta mahasiswa diwawancarai serta diobservasi untuk mendapatkan data yang terlibat dalam proses belajar dan mengajar agama Islam di perguruan tinggi umum. Kemudian, analisis isi digunakan untuk menilai data yang diperoleh dengan menggunakan teknik analisis data kualitatif. Temuan penelitian menunjukkan bahwa masih ada ruang untuk perbaikan dalam standar pengajaran agama Islam di perguruan tinggi umum, terutama dalam hal pengajaran dan pembelajaran yang masih di bawah standar. Kurangnya penekanan pada pendidikan karakter, pengajaran yang buruk, dan minimnya penggunaan teknologi dalam proses belajar mengajar merupakan beberapa alasan yang berkontribusi terhadap rendahnya kualitas pendidikan agama Islam di universitas umum. Oleh karena itu, pendidikan karakter, peningkatan standar pengajaran, dan penerapan teknologi yang lebih baik dalam proses pembelajaran dan pengajaran agama Islam di era 5.0 sangat diperlukan untuk meningkatkan kualitas pengajaran agama Islam di perguruan tinggi umum.)
