Call scope:
The Indonesian Science Fund (Dana Ilmu Pengetahuan Indonesia, DIPI) has recently
been established under the auspices of the Indonesian Academy of Sciences (AIPI).
This 2016 Research Call aims to provide grants for research in the following two
focus areas:
* Life, health and nutrition
* Identity, diversity and culture
Competitive research grants up to three years and IDR 1,5 billion/year will be
offered for researchers from Indonesia to pursue high-quality scientific research
projects. The funder aims to support fundamental, frontier, and excellent research
in the above two focus areas of importance to Indonesia’s future. For this 2016
Research Call, Principal Investigators applying for the grants are required to be of
Indonesian nationality and based in Indonesia. Domestic and international
collaborations between researchers and their institutions are encouraged, as are
interdisciplinary projects, but neither is a requirement. The expected result of the
research must be eligible for publication in highly reputable scientific journal.
Pemanfaatan e-learning sebagai salah satu penunjang pembelajaran saat ini telah berkembang luas di UGM, diantaranya dengan terus digunakannya situs e-learning yang dibuat oleh dan untuk komunitas di UGM. Untuk lebih meningkatkan pemanfaatan dan peran e-learning, maka Pusat Inovasi dan Kajian Akademik (PIKA) UGM mengadakan Hibah e-learning yang ditujukan bagi staf pengajar di UGM dalam pemanfaatan e-learning sebagai penunjang pembelajaran.
Kegiatan hibah ini terbagi menjadi 2 tipe:
- Tipe A: pengembangan bahan ajar multimedia dengan dana maksimal
Rp15.000.000 untuk 15 penerima hibah. - Tipe B: pengembangan matakuliah diarahkan untuk Massive Open On-line Course (MOOC) dengan dana maksimal Rp 30.000.000 untuk 5 penerima hibah.
Batas waktu pengumpulan proposal Senin, 16 Mei 2015 jam 15.00.

Abstract
Adsorption of Hg(II) ions onto selective adsorbent of dithizone-immobilized natural zeolite (DIZ) from Wonosari, Yogyakarta, Indonesia has been investigated in batch mode. Some parameters influencing immobilization of dithizone and adsorption of Hg(II) were optimized including effect of temperature and reaction time on the effectiveness of dithizone immobilization as well as effect of pH, contact time and initial concentration of Hg(II) ion on the efficiency of the Hg(II) adsorption. Preliminary application of the adsorbent in the removal of Hg(II) ion in river water spiked with Hg(II) was also studied. The FT-IR and XRD analytical results show that the surface of natural zeolite can be modified by immobilization of selective organic ligand towards Hg(II) ions. The optimum conditions for the adsorption of Hg(II) is achieved at pH 5 and 90 min of contact time. Kinetics and adsorption isotherm studies suggest that the capacity, affinity and selectivity of the DIZ in adsorbing hazardous metal ions such as Hg(II) is significantly improved compared to those of non-immobilized activated natural zeolite (AZ). The Hg(II) adsorption capacity for AZ and DIZ at optimum condition is 8.0 and 13.1 µmol/g, respectively and the both adsorption follows first-order reaction. It has also been demonstrated that the DIZ adsorbent may be applied in the removal of Hg(II) ion in the river water spiked with Hg(II) ion up to 99.36% from the initial concentration of 8 mg L-1 in two serial batch adsorptions.
