Day of Discovery: Learning DNA Sequencing in Plant Science


     Today, we attended a short but insightful lecture on DNA sequencing as part of our exchange program at IPB University. The session was held in preparation for our hands-on laboratory activity scheduled for tomorrow, where we’ll be working alongside the Plantation Production Management class. It was a fascinating introduction to a field that plays a crucial role in modern plant science and agriculture.

     ~ During the lecture, we learned about the structure and function of DNA (Deoxyribonucleic Acid)—the molecule that carries the genetic instructions for all living organisms. DNA is made up of four nucleotide bases: adenine (A), thymine (T), cytosine (C), and guanine (G). These bases pair in specific ways (A with T, and C with G) to form the famous double helix structure.



     DNA sequencing refers to the process of determining the exact order of these bases in a DNA molecule. By understanding this sequence, scientists can identify genes, study genetic variation, and even modify plant traits through selective breeding or genetic engineering.


     The purpose of this lecture was to give us a foundational understanding of how DNA works so we’ll be more prepared and engaged during tomorrow’s lab activity. Knowing the basics of DNA sequencing helps us appreciate how genetic information can be used to improve crops, enhance yield, and develop disease-resistant plant varieties—all of which are crucial for food security and sustainability.


     ~ It’s truly amazing to think about how brilliant scientists were to discover DNA and its applications in plant breeding. Their work has opened doors to evolving agriculture, expanding scientific knowledge, and making the world a better, more sustainable place to live. We’re excited to apply what we’ve learned in the lab tomorrow and continue exploring the science behind the plants we grow and consume.

Day One Diaries: Firsts That Last

Image
    On April 16, 2025, as of our academic journey, students and lecturers from Guimaras State University - Baterna Campus, Philippines were given a wonderful opportunity to visit IPB University in Bogor, Indonesia. This experience became more than just an academic presentation—it was a beautiful blend of culture, learning, and connection.       Upon our arrival, we were warmly welcomed by the faculty and students of IPB University. Their hospitality was truly felt by all of us. The event began with a research presentation delivered by two of our lecturers, who shared their studies and areas of expertise. The participants from IPB University actively engaged by asking insightful questions, driven by curiosity and a strong desire to explore innovative ideas. Our lecturers addressed each question professionally, providing clear and thoughtful answers.     As the presentations wrapped up, four of us students prepared to showcase a piece of Philippine cultu...

From Lecture to Life: Drawing Plants and Grafting Cacao

Image
     On our 9th day as exchange students at IPB University, we had another exciting and enriching experience that blended classroom learning with practical fieldwork. The day was filled with discovery, skill-building, and bonding with classmates — a perfect blend of science and friendship.      We began the day with a lecture on Seed Technology alongside our classmates. Our task was to identify various plant samples that were brought to class and sketch them. While working on the activity, I managed to sneak in a quick breakfast since I was feeling quite hungry — luckily, the teacher had already finished the lecture and the atmosphere was relaxed, giving us the freedom to work at our own pace.      After completing our plant drawings, we headed to the shed for a hands-on grafting activity. Each of us was given a cacao rootstock and a cutter to collect our own scion from a cacao tree. The challenge was to select the right size of scion tha...

My Second Day; An Unforgettable Day of Learning and Discovery as an Exchange Student in Indonesia

Image
     •••    As exchange students in Indonesia, every day presents new experiences and adventures. Our second day was a perfect example of how stepping outside of our comfort zone can lead to memorable encounters, new friendships, and an incredible learning journey. From attending our first class to visiting one of the most advanced laboratories at IPB University, this day was filled with excitement, surprises, and knowledge. —-We woke up early, eager to attend our first official class, but ended up entering late because we weren’t sure of the exact location. We wandered around the Gedung Gada Kandang building, searching for our lecture room. Eventually, we found a room near the aquaculture area, knocked on the door, and saw a class already in session. Unsure if it was the right one (since we didn’t know our classmates yet), we closed the door and waited outside, hoping someone would guide us.    After a few minutes, a student opened the door and invi...
