Abstract

This study discusses conventional bioethanol production through fermentation as a response to the need for environmentally friendly alternative energy sources. The objectives of this practicum are to understand the basic principles of fermentation, identify the factors that influence it, carry out a simple fermentation process using natural materials (sugar/corn/cassava) and Saccharomyces cerevisiae yeast, and analyze the results. The methods used include preparing a sugar solution, inoculating yeast, anaerobic incubation at 30–35 °C for 2–5 days, observing CO₂ formation, filtration, and simple purification through distillation. The study employed an experimental design, with 63 biology education students participating. The results of the practicum indicate that students understand the success rate of bioethanol fermentation, as evidenced by the formation of CO₂ bubbles and the feasibility of ethanol separation by distillation. Students can understand the factors that influence conventional bioethanol production.

Abstract

Polymerase Chain Reaction (PCR) is a fundamental biotechnology technique used to amplify specific DNA fragments in large quantities through in vitro replication. This virtual laboratory aims to (1) understand the basic principles and working stages of PCR, (2) identify the main functions of PCR components, and (3) apply PCR simulations to amplify target genes using the LabXchange platform. The research was conducted virtually, using an interactive experimental approach, by 60 Biology Education students working in one group. Data were collected from student worksheets and simulation outputs. The results showed that students were able to identify and explain each stage of the PCR process, including denaturation, annealing, and extension, as well as analyze the roles of the DNA template, primers, dNTPs, buffer, and Taq polymeraseenzyme. The simulation successfully demonstrated efficient amplification of the target gene. These findings indicate that virtual laboratory learning effectively enhances students’ conceptual understanding and analytical skills in biotechnology.

Abstract

Perundungan (bullying) merupakan fenomena sosial yang mengancam perkembangan psikologis dan akademik siswa di sekolah. Kegiatan pengabdian ini bertujuan untuk mendeskripsikan peran mahasiswa KKN sebagai agen perubahan dalam mengedukasi pencegahan perundungan di SMPN 2 Cisoka, Desa Caringin Tangerang. Masalah utama yang diidentifikasi adalah tingginya normalisasi terhadap kekerasan verbal di lingkungan sekolah pedesaan. Metode yang digunakan adalah Peer Education yang melibatkan 55 perwakilan siswa dari kelas VII, VIII, dan IX (2 orang per kelas) sebagai sasaran antara. Mahasiswa berperan sebagai edukator, fasilitator, dan motivator melalui workshop interaktif, media audio-visual, dan simulasi peran. Hasil evaluasi menunjukkan peningkatan signifikan pada pemahaman peserta, di mana pengetahuan kategori "Baik" melonjak dari 21,1% menjadi 89,5% pasca-intervensi. Kontribusi mahasiswa sebagai agen perubahan terbukti efektif dalam mentransformasi persepsi siswa mengenai perundungan dan membangun keberanian moral untuk melaporkan kekerasan. Disimpulkan bahwa kehadiran mahasiswa mampu menjembatani hambatan komunikasi di sekolah dan menginisiasi budaya sekolah yang lebih inklusif dan aman.
