ITROSCO, SEMARANG – Fifth day of ITroSCo (24/8), Virleon as a Master of Ceremony of the day opened the event very warmly; after his opening speech and greeting all participants, Virleon then handed over to Dr. Mada Triandala, S.Pi., M.Si. to lead as a moderator for today. Prof. Junichi Tanaka gave the first lecturer, Prof. Tanaka, talking about Indonesia’s marine ecosystems from an international researcher’s point of view. As Prof. Tanaka has been involved in biodiscovery projects from coral reef organisms in Okinawa, located between Taiwan and mainland Japan, we screened hundreds of marine invertebrates and algae, from which we characterized secondary metabolites. Prof. Tanaka also had opportunities to visit Indonesia between 1997 and 2011 under collaborative projects between Indonesia and Japan. Although his experience on Indonesian coral reef organisms is limited, Prof. Tanaka hopes to talk about marine natural products study in several aspects: introduction to this field, chemical space, similarities and differences in the marine bioresources between Indonesia and Okinawa and other related issues for research. In the question and answer session, Mr. Tanaka got some questions about marine coral in Indonesian waters from the participant. They enjoyed Mr. Tanaka’s presentation.

After taking some pictures for the documentation session, we moved on to the ice-breaking session. Rayyen led this ice-breaking session as Person in Charge. In the ice-breaking session, we play a game on a web called gartic, where everyone can draw anything based on the clue, and the other participant can type and guess the answer. Everyone can share their creativity during this game and have much fun like the day before; we also had a break session where it took 30 minutes of free time.
To the following agenda, right after the break session, we had a second lecturer. Agus Trianto gave the second lecturer, ST., M.Sc., Ph.D., where Mr. Agus presented Marine Natural Products from Indonesia’s Traditional Knowledge for Future Biopharmaceuticals. The geographical position between two oceans and two continents makes Indonesia a country with mega diversity, both terrestrial and marine biota. A large number of Indonesians live in coastal areas and depend on marine resources for their livelihoods. They also use coastal and marine plants and animals for the treatment of various ailments and to increase stamina. However, the low culture of literature has become an obstacle to collecting complete prescriptions on marine and coastal organisms for medicinal purposes. Some animals and plants are still used as drugs or stamina enhancers, but many are no longer used because they have been replaced with modern medicines. Bioactivity of compounds in various seaweeds can be used for anti-tumor, antioxidant, anti-diabetic and reduction or prevention of, anti-obesity, and many more.
The seaweed market is very high and keeps increasing year by year. Mr. Agus also talked about the benefits of sea urchins and how to consume them. Sea urchins are also proven to contain several amounts of anti-inflammatory. Mangrove spreads in most of Indonesia’s coastal areas. Mangroves are plants with high flavonoid content; flavonoids can produce compounds such as anti-inflammatory, anti-hepatotoxic, and antioxidants that can be used to ward off free radicals. Black coral or known as akar bakar, is not a plant, but it is an animal. Traditional drug based on black coral. Traditional people use this black coral for a magical medicine. For people on Sabu-Raijua Island, East Nusa Tenggara use the bahar root as a medicine. Black coral contains radium in small amounts, then Mr. Agus talking about the benefit of radium itself. To close the presentation, Mr. Agus was joking around to invite all participants to fly ahead to Karimun Jawa to see sea urchins together after this pandemic ends.
During the question and answer session, Dr. Agus also actively communicated between him and the participant. After taking a picture together to close the second session, we went straight forward into the game session where we played Mentimeter; Farras became Person in Charge on this session. We were playing Mentimeter, where a question you have to answer true or false with some explanation facts from Farras as a Person in Charge of the day after the results come up. For this game, we do it twice with different and interesting questions; in this session, we could see the answer from the participant by Farras sharing the screen so we can see the different perspectives from other participants. After playing the game twice with Farras adding some fun comments about the participant’s answer. We closed the game with fun and joy. (Committee of ITroSCo 2021)
