My final project is the effect of hydrothermal holding time to zeolite characterization which synthesized by geothermal sludge. Zeolite is a smart material. It is belong to microporous material and has many advantages such as filter, adsorbent, ion exchanger and the others. I took the gothermal sludge from geodipa energy, the owner of geothermal plant in Dieng, Wonosobo. Geothermal sludge was dried and was distilled, and then fused at 850 deg C. Geothermal ash mixtured with natrium aluminate and natrium silicate to get an aluminosilicate gel. It was synthesized hydrothermally at 100 deg C during 3,4,and 5 hours.Then,it was washed by aquabidest and was dried in the oven at 80 deg C during 5 hours. Finelly zeolite was produced by the process.

By the way, indonesia has many beautiful beaches in every island. It is not less bautiful than the other beaches in the world. Example, The famous beach in Bali, Kuta beach. But there are many beautiful beaches that unexposed by media, like sundakh beach. Only local visitor who visit this beach, no one from foreign people. I like this beach, clean with white sands
Jaman-jaman jadi mahasiswa baru, itulah jaman dimana kita mulai ditindas hahaha, ga enak kalo dirasain , tapi enak kalo diinget, bikin ngakak juga. Alhasil kini saya sudah menjadi senior karena dunia itu berputar, yang dulunya jadi junior sekarang jadi senior, tapi kalo udah jadi senior udah sibuk mikir tugas akhir. Bersabarlah bagi mahasiswa baru yang baru masuk dan belum dianggap di kampus tercinta, yang penting lakukan yang terbaik untuk kampus tercinta, nanti masamu menjadi senior akan datang juga hahaha.
