Vol. 7 No. 1 (2016): Vol 7 No 1 (2016)

We offer our praise and gratitude to the presence of God Almighty because thanks to His grace and guidance, the Global Atmospheric Monitoring Station (GAW) Bukit Kototabang data has again published the MEGASAINS Bulletin.

In its publication, which has entered its 7th Volume in 2016, the MEGASAINS Bulletin appears with a new face and presentation design. Starting with this edition, the MEGASAINS Bulletin uses a logo in the form of a circle with a combination of green, white and blue gradations, and is equipped with a blue shadow. This logo reflects the MEGASAINS Bulletin study which focuses on Scientific Writing (KTI) in the fields of Meteorology, Climatology, Air Quality and Geophysics (MKKuG), as well as the environment. Changes to the layout have also been introduced by utilizing a two-column display on each page.

For this edition, six KTIs from various scientific disciplines are presented. In the field of meteorology/atmospheric physics, radiation measurements in the 2015 period at Kototabang Hill are reviewed in more depth. In the field of climatology, the concept of probability is used for dry land in Lombok by referring to intervals and rainfall. In other KTI, the frequency of rainfall from six different locations in Indonesia was also analyzed to determine the normal seasons in Indonesia. In the field of air quality, the WRFChem model is applied to determine air quality in West Sumatra. In the field of geophysics, analysis of the seismic gap on the Sumatran Fault. In the environmental sector, landslide incidents in South Aceh were studied using Landsat 5 satellite imagery.

Supported by the enthusiasm of all GAW Bukit Kototabang Station staff in their support for the continued publication of the MEGASAINS Bulletin, the Editorial Board certainly hopes that this KTI can encourage the creation of improvements in MKKuG services in the future. In addition, the emergence of awareness in carrying out research principles is also expected to support increased knowledge and performance in carrying out daily tasks.

There is no ivory that is not cracked, and the same goes for this issue of the MEGASAINS Bulletin which is still far from perfect. Therefore, the Editorial Board really hopes for suggestions and constructive input to improve its publications in the future.
