Abstract

In the context of higher education, the digital era and advancements in technology have revolutionized learning systems, necessitating an understanding of student preferences for online, offline, and hybrid methods. This study aims to investigate these preferences and the associated reasons behind them. Data were collected through a Google Form survey administered to 110 students of chemistry department, chemistry education study program, Universitas Negeri Medan, complemented by semi-structured interviews with a subset of participants. Results reveal that 9.1% of students prefer online learning due to its flexibility and cost-effectiveness, 55.5% favor offline (face-to-face) learning for its effectiveness in understanding material and fostering interaction, and 35.5% opt for a combination of both methods, which is perceived as the optimal balance. The findings underscore the importance of adapting learning methods to enhance educational effectiveness, addressing challenges such as internet access, device limitations, and transportation costs.

Abstract

The purpose of this development and research is to ensure whether the stop motion video learning media is effective in teaching Biology material on the human circulatory system. Experts in the field of media and materials have evaluated this idea. The development model used in this research is the ADDIE model. The subjects of this study are 11th grade high school students. The instrument used is a student response questionnaire. The data analysis results show that the expert lecturer's validation of the feasibility of stop motion videos scored 4.0 with a good category, and the reliability test shows an agreement percentage of 85.3% (reliable). Other reliability test results show an agreement percentage of 80.1% (reliable), with a stop motion video feasibility validation score of 3.9 and a good category. From these results, it can be concluded that the use of stop motion videos in teaching the human circulatory system material is very possible and can be one alternative method for learning Biology.

Abstract

Salah satu cara untuk mengembangkan, menerapkan, dan menarik kesimpulan dari pembelajaran IPA adalah melalui pembelajaran Kimia. Penambahan terbaru pada paradigma pembelajaran yang ada adalah Problem Based Leaning (PBL), yang menggunakan tindakan siswa untuk memecahkan masalah dan dapat diselesaikan secara individu atau kelompok dalam fase dan jangka waktu yang telah ditentukan. Berdasarkan uraian tersebut, maka dilakukan penelitian di bidang Biokimia Politeknik Tanjungbalai untuk mengetahui derajat mahasiswanya. Hasil penelitian diperoleh bahwa pre-test hanya 17% yang lulus tes dengan nilai skor 70. Pembelajaran post-test melalui PBL menunjukkan 100% lulus tes. Pada kategori sedang nilai g faktor sebesar 0,565, sedangkan pada kategori cukup efektif persentasenya sebesar 56,462%.

Abstract

Program pengabdian kemitraan masyarakat (PKM) ini bertujuan untuk melakukan pendampingan kepada mitra dengan memanfaatkan buah nanas sebagai bahan fermentasi untuk memperbaiki mutu aroma dan cita rasa kopi. Hal ini dilakukan berdasarkan hasil observasi awal yang dilakukan oleh tim pengusul yaitu : 1) Proses pengeringan kopi yang tidak seragam, dan 2) Mutu aroma dan cita rasa yang masih kurang bagus. Penyebabnya karena bahan kopi robusta yang dibeli ke petani memiliki tingkat mutu yang berbeda. Dampaknya, harga kopi menjadi rendah. Mitra PKM ini adalah Usaha Pucako Roastery di Kelurahan Amplas, Kota Medan. Metode pelaksanaan PKM ini dilakukan melalui dua tahapan utama yaitu: 1) Pembuatan bubur buah nanas, dan 2) Fermentase kopi menggunakan bubur nanas. Melalui PKM ini diharapkan terjadi perbaikan mutu aroma dan cita rasa kopi serta dapat meningkatkan penjualan mitra. Adanya enzim bromelin pada bubur nanas akan dapat menurunkan kadar kafein karena enzim ini mampu memecahkan senyawa yang mirip protein pada kopi.

Abstract

Indonesia is one of the largest coffee producing and exporting countries in the world. One of the types of coffee that is famous in Indonesia is arabica coffee. This study examines the impact of different gas environments (open, semi-closed, and closed) on the fermentation process of Arabica coffee beans (Coffea arabica L.) at various temperatures (40°C, 60°C, and 80°C). The key factors analyzed were the moisture content and pH levels of the beans after fermentation and roasting. The findings revealed that both gas environment and temperature had a significant effect on the moisture content and pH of the beans, with higher temperatures (80°C) leading to a faster reduction in moisture. Additionally, the pH level was higher under open gas conditions. This research offers valuable information on how fermentation conditions influence the chemical properties and qualities of Arabica coffee beans.
