Abstract

Kelulusan tepat waktu merupakan salah satu indikator penting keberhasilan penyelenggaraan pendidikan tinggi. Salah satu faktor yang diduga memengaruhi kelulusan tepat waktu adalah kualitas pembimbing akademik yang dirasakan oleh mahasiswa. Penelitian ini bertujuan untuk menganalisis pengaruh persepsi mahasiswa terhadap kualitas pembimbing akademik terhadap kelulusan tepat waktu. Penelitian ini menggunakan pendekatan kuantitatif dengan metode survei. Populasi penelitian adalah mahasiswa pada perguruan tinggi yang menjadi objek penelitian, dengan sampel yang ditentukan menggunakan teknik probability sampling sebanyak 150 responden. Data dikumpulkan melalui kuesioner dengan skala Likert dan dianalisis menggunakan regresi linear sederhana. Hasil penelitian menunjukkan bahwa persepsi mahasiswa terhadap kualitas pembimbing akademik berpengaruh positif dan signifikan terhadap kelulusan tepat waktu. Temuan ini mengindikasikan bahwa semakin baik kualitas pembimbing akademik yang dirasakan mahasiswa, maka semakin besar peluang mahasiswa untuk menyelesaikan studi sesuai dengan masa studi yang ditetapkan. Penelitian ini memberikan implikasi bahwa peningkatan kualitas pembimbingan akademik perlu menjadi perhatian strategis perguruan tinggi dalam upaya meningkatkan tingkat kelulusan tepat waktu mahasiswa.

Abstract

Hari Bumi ke-55 tahun ini diperingati dengan "Gerakan Penanaman 1 Juta Bibit Matoa" sebagai wujud tanggung jawab kolektif dalam merawat kelestarian bumi dan merespons krisis iklim serta kerusakan alam. Kegiatan ini merupakan sinergi konservasi dan edukasi, khususnya di Tempat Pemakaman Umum (TPU) Muslim Simalingkar B, Medan, sebagai model rehabilitasi Ruang Terbuka Hijau (RTH). TPU Muslim Simalingkar B dipilih karena ketersediaan lahan terbuka yang luas namun masih tandus, menyebabkan suhu tinggi, degradasi tanah, dan menurunnya fungsi ekologis. Metode pengabdian ini menggunakan pendekatan partisipatif dan edukatif, melibatkan berbagai mitra seperti pemerintah daerah (Kementerian Agama Kota Medan, Pemerintah Kota Medan, BPDASHL Asahan), komunitas (Fosil BKMI Kota Medan, Perwaku, Fordas Wampu Ular), perguruan tinggi (Universitas Amir Hamzah, Universitas Tjut Nyak Dhien), dan mahasiswa. Tahapan kegiatan meliputi persiapan, sosialisasi dan pelatihan, penanaman, pemeliharaan dan monitoring, serta edukasi berkelanjutan. Hasil utama kegiatan ini mencakup penanaman 1.000 bibit matoa di TPU Muslim Simalingkar B, terbentuknya area percontohan penghijauan TPU, serta peningkatan pengetahuan dan keterampilan masyarakat, mahasiswa, dan mitra dalam teknik penanaman dan pemeliharaan pohon matoa. Dampaknya termasuk peningkatan fungsi ekologis lahan pasif, implementasi keilmuan Program Studi Agroteknologi, peningkatan kesadaran dan partisipasi masyarakat, serta terjalinnya kolaborasi lintas sektor. Keberhasilan kegiatan dinilai dari partisipasi masyarakat dan kesadaran kolektif bahwa menjaga bumi adalah tanggung jawab bersama, merupakan investasi jangka panjang untuk generasi mendatang.

Abstract

The development of artificial intelligence (AI) technology has brought significant changes to the world of education, particularly in the process of preparing students' academic assignments. One widely utilized innovation is ChatGPT, which can help students generate ideas, develop writing outlines, and improve the quality of academic language and structure. This study aims to analyze the use of ChatGPT in supporting students' academic assignment preparation process and identify the benefits and challenges faced in its use. This study used a qualitative approach with a descriptive research type. Data were collected through interviews, observations, and documentation of students who used ChatGPT in academic activities. Data analysis was conducted using thematic analysis techniques through the stages of data reduction, data presentation, and conclusion drawing. Data validity was maintained through triangulation of sources and methods to ensure the accuracy and credibility of the research results. The results show that the use of ChatGPT has a positive impact on improving the efficiency and quality of academic assignment preparation, especially in terms of idea development, writing structure, and language improvement. However, the use of this technology also poses challenges, such as potential dependency, decreased critical thinking skills, and the risk of violating academic ethics. Therefore, it requires wise and responsible use and support from educational institutions in the form of policies and guidelines for the use of AI.

Abstract

Pengabdian ini bertujuan untuk meningkatkan kapasitas dan daya saing pelaku UMKM melalui pengembangan produk snack berbasis pisang lokal. Metode pelaksanaan yang digunakan mencakup pelatihan teknis, demonstrasi, serta pendampingan berkelanjutan yang berorientasi pada peningkatan keterampilan produksi, diversifikasi produk, dan penguatan manajemen usaha. Hasil kegiatan menunjukkan adanya peningkatan signifikan dalam pengetahuan dan keterampilan mitra, yang tercermin pada kemampuan mengolah bahan baku secara lebih higienis dan efisien, serta menghasilkan produk yang lebih variatif dan inovatif. Selain itu, terjadi peningkatan kualitas produk dan konsistensi proses produksi, disertai dengan penguatan identitas produk melalui branding dan inovasi kemasan. Dalam aspek pemasaran, mitra mulai mengadopsi strategi yang lebih luas, termasuk pemanfaatan media digital untuk memperluas jangkauan pasar. Dampak lain yang teridentifikasi adalah meningkatnya kemandirian dan kepercayaan diri pelaku UMKM dalam mengelola usaha, serta bertambahnya potensi ekonomi melalui peningkatan volume produksi dan diversifikasi pasar. Meskipun demikian, pelaksanaan program masih menghadapi tantangan berupa keterbatasan sumber daya, inkonsistensi dalam penerapan standar kualitas, dan kesenjangan literasi teknologi. Secara keseluruhan, kegiatan ini memberikan kontribusi nyata dalam memperkuat kapasitas dan daya saing UMKM berbasis potensi lokal, serta membuka peluang pengembangan usaha yang lebih berkelanjutan.

Abstract

This study aims to evaluate the impact of implementing virtual simulation in Biology learning on concept understanding by Agrotechnology students. Along with the development of technology, technology-based learning, especially virtual simulation, has begun to be applied to support the understanding of more complex concepts. Although a number of previous studies have shown the successful use of virtual simulations in various disciplines, there are still research gaps that need to be filled regarding the application of virtual simulations in the context of Biology education, especially in Agrotechnology study programs. This creates a phenomenon where students have difficulty in understanding these concepts. This research fills the gap by evaluating the application of virtual simulation as a learning method in overcoming this challenge. Using an experimental method, this study involved 30 students as samples, who were tested using pretest and posttest to measure the improvement of their understanding of Biology concepts. The results of the analysis showed that the application of virtual simulation resulted in a significant increase in students' understanding, which was reflected in the N-gain score with an average of 78.25. This value indicates a substantial increase in understanding of Biology concepts after using virtual simulation as a learning method. This finding supports the effectiveness of virtual simulation in improving the understanding of complex concepts, so it can be an effective alternative in learning in Biology. The results of this study provide positive implications for the use of technology in education, especially in improving the quality of learning in higher education
