Super Longan is result of research by Dr. Hidayat Teguh Wiyono, M.Pd. a lecturer at Department of Biology, Faculty of Mathematics and Natural Sciences, University of Jember. The Super Longan stems from Pak Teguh concern about the Jember local longan plant which initially only grew without fruit. One of the reasons is that the hot temperature in Jember Regency makes longans do not want to flower to process into fruit. Furthermore, Pak Teguh said that longan Jember will flower only if stimulated so that it can bear fruit, without being stimulated with a booster it cannot. With special ingredients and packaged in the form of fertilizer, it is able to produce thick, sweeter longan fruit and smaller seeds. It was proven when holding the harvest on terrace of the Biology Department, FMIPA University of Jember a few days ago, The FMIPA of UNEJ community tried firsthand the advantages of super longan. “The flesh of the fruit is thick, tastes sweet and what is different is that the seeds are smaller than other longans,” said one of the staff at FMIPA UNEJ. Dozens of super longan bundles were prepared by being transported by Pak Teguh’s own unique vehicle. Several FMIPA staff who came to Biology building also received many stories about the management of super longan. The super longan, which was the result of Pak Teguh’s research, was also planted in the Banyuwangi, Lumajang, Bondowoso, and Situbondo areas of course with a booster.Mr. Teguh in producing super longan has long been concerned with longan fruit. It is told from a collection of longans that have been stimulated by a booster and then transplanted. From there, superior seeds are produced so that they get special fruit too. Accompanied by students, the event on the terrace of Biology Department, FMIPA UNEJ lasted until late in the afternoon and was attended by many visitors. “The fruit is big and fresh, so a lot of visitors come here” said one student.

Dr. Hidayat Teguh Wiyono, M.Pd. is a graduate of Institut Keguruan dan Ilmu Pendidikan Malang for S1 and S2. While the Doctorate degree was obtained from Airlangga University, Surabaya. Pak Teguh is a senior lecturer in the Biology Department, FMIPA UNEJ who produces a lot of research, dedication and also guides students, especially in field activities..
