Abstract

This research analyzes misconceptions in the 2013 Biology curriculum book for class X, especially regarding ecosystem material. Using qualitative descriptive methods, this research identifies parts of the book that have the potential to cause misconceptions and involves interviews and questionnaires with students and teachers. The results show that less than 10% of concepts experience misconceptions, with the highest level of misconceptions in the concepts of food chains and energy flow. Most misconceptions are caused by students' lack of understanding of teacher explanations that are difficult to understand. Students tend to look for references on the internet to clarify material, but this also has the potential to increase misconceptions if the source is not clear. Lecture-based learning methods and the use of PowerPoint media without in-depth explanations also contribute to misconceptions. This research emphasizes the importance of meaningful and participatory learning to reduce student misconceptions.

Abstract

The purpose of the study was to analyze genetic disorders in humans based on 10 national and international based journals. This research method uses a literature review design. From the results obtained, the pure genetic disease found was Down syndrome, with a total of 13 cases in four years. Other diseases that can be influenced by genetic factors such as primary hypertension, asthma, and schizophrenia were also found in sig1nificant numbers.

Abstract

This research discusses the effect of fermentation time on the taste and texture quality of yogurt through a literature study approach. Yogurt is a popular fermented milk product because it contains probiotic bacteria, such as Lactobacillus bulgaricus and Streptococcus thermophilus, which can improve digestive health. A fermentation process that utilizes lactic acid bacteria converts lactose into lactic acid, which acts as a natural preservative and determines the taste and texture of yogurt. Fermentation time is a crucial factor that influences the organoleptic and microbiological quality of the product. This research uses data from various scientific journals. The results showed that the duration of fermentation influenced the degree of acidity (pH), viscosity and total lactic acid bacteria in yogurt. Fermentation that is too long can cause a decrease in textural quality due to a decrease in pH approaching the isoelectric point of casein, thereby causing phase separation. This study also found that the concentration of fruit juice in yogurt had a significant effect on the acidity of the product. The conclusion of this study shows that managing the fermentation duration is very important to produce high quality yogurt. It is hoped that this article can be a reference for innovation in making fermented products, as well as a learning resource in biology education.

Abstract

Penelitian ini bertujuan untuk mengamati teknik budidaya tanaman hortikultura pada ubi jalar (Ipomoea batatas) di Desa Lau Dendang. Ubi jalar merupakan komoditas pertanian yang memiliki potensi tinggi sebagai sumber karbohidrat dengan kandungan gizi yang baik. Namun, produktivitasnya di Indonesia masih belum optimal akibat keterbatasan keterampilan petani, penggunaan pupuk yang kurang efisien, serta penanganan pascapanen yang belum maksimal. Penelitian ini menggunakan metode eksplorasi dengan pendekatan observasi lapangan, wawancara, dokumentasi, dan studi literatur. Hasil penelitian menunjukkan bahwa teknik budidaya yang efektif meliputi persiapan lahan dengan pembuatan guludan, penggunaan bibit berkualitas, pemeliharaan dengan pemupukan dan pengairan yang tepat, serta pengendalian hama secara ramah lingkungan. Panen dilakukan pada umur tanaman 3-4 bulan dengan proses seleksi dan sortasi untuk menjaga kualitas hasil. Dengan penerapan teknik budidaya yang optimal, produktivitas ubi jalar dapat ditingkatkan, sehingga mendukung ketahanan pangan dan meningkatkan nilai ekonomi bagi petani.
