"Comic survival science series 24 ini menceritakan ttg science pemanasan global cuaca atau perubahan iklim, lalu hal apa yang bisa kita lakukan untuk menjaga Bumi?"

"Buku yang ditulis bersama dan saya sunting ini unik dan asli dan penilitian dan pengalaman penulis-penulisnya di bidang pendidikan, industri dan organisasi, kesehatan mental dan fisik, masyarakat, dan kebijakan. Selain dari penelitian dan pengalaman, mereka juga membandingkan dengan bahan acuan yang ada. Bahasa yang digunakan dalam buku ini sederhana dan mengalir sesuai dengan hasil penelitian dan pengalaman mereka, sehingga isinya mudah dibaca."

"Periodic magnetic storms are those related to reccurent coronal hole events within a period of one solar rotation. There are still few studies on successive periodic magnetic storm. In this paper, we discuss the nature of the amplitude of the periodic magnetic storms within the solar cycle 20,21,22, and 23. The periodic nature of solar wind ( 27 days) occured on descending phase of solar cycle 22 also caused a reccurent geomagnetic disturbance. The disturbance developed into a geomagnetic storm in the first (27 days) and the ninth rotation. The geomegnetic disturbances with period 27 and 13.5 days are both significant at the low latitude while the period of 30 days are more dominant at the high latitude. That mean, from two flows of high velicity plasmas, only one that higher contribution on the occurence of geomagnetic disturbance accompanied by high intensity southern Bz field."
