Dr. Lideman, S.Pi, M.Sc. is an alumnus of Kagoshima University, Japan (2006-2012). After a year as a research student on the experimental culture of Sargassum hornery and Laurencia brongiartii, his master’s and doctoral research focused on carageenophytes, especially eucheumatoid seaweeds, including photosynthesis, physiology, and the effect of environmental factors. In 2019 he was awarded a JSPS Invitational Fellowship for Research in Japan, again at Kagoshima University, on the effect of irradiance and temperature on stress and recovery of Kappaphycus alvarezii (local and tissue culture types) from South Sulawesi. A researcher at the Takalar Brackish-water Aquaculture Station of the Ministry of Marine Affairs and Fisheries since 1998, he has been involved in several ACIAR collaborations. In 2020 he was awarded a patent for a method for Gracilaria sp. reproduction from spores. His research interests include the sexual (spore) and asexual (e.g. tissue culture and grafting) propagation of seaweeds and practical applications in aquaculture, seedling acclimation, photosynthesis and the effect of environmental factors on wild and farmed seaweeds, seaweed biodiversity, the use of seaweeds in aquaculture of other organisms (e.g. shrimp and fish), and the use of seaweed processing waste streams. In addition to national and international scientific publications, he has produced popular articles on subjects including the cultivation of seaweeds by “planting” spores on ropes, and is active in developing and promoting the implementation of good aquaculture practices in Indonesia.
