Abstract

Activation of rattan charcoal is carried out to increase pore size and formfunctional groups. In this study, activated carbon from rattan has been made withdifferent activation times. The research objective was to determine the pore size andfunctional groups contained in the activated carbon of rattan with an activation time of 5hours and 10 hours. The solution used to activate rattan activated carbon is KOH 10 mlcharcoal 10 grams with a burning temperature of 1500C. The results of rattan activatedcarbon were characterized using SEM and FTIR to see the pore size and functionalgroups. The activated carbon sample of rattan with the activation time of 5 hours had apore size that was not too large and only a few were formed and the sample of 10 hoursof activation time had a large pore size. The samples for 5 hours and 10 hours ofactivation have the same functional groups, namely O-H, C-C, C-O, C-H.

Abstract

Bitung district was an active seismic area in North Sulawesi Province. This is because of platetectonic activity, among other things, subduction of West Molucca Sea and subduction of NorthSulawesi Trench that can cause earthquake disaster. Earthquake is an unpredictable disaster thatcan pose a danger to a region. So the purpose of the research is to minimize the impact of theearthquake disaster. The study conducted with study of the earthquake hazard analytics usingprobability approaches with 500-year-old return period, probability exceeded 10% in 50 years ofbuilding age in condition T= 0 second, T= 0.2 second and T= 0.1 second. PSHA’s calculation in theBitung region were obtained at PGA value of the same amount 1.4g – 1.8g, SA value T= 0.2 secondis 1,7g-2,1g and SA value T= 1,0 second is 0,5-0,6g. as for the turbulence of the result of teconversion of the PGA value being on the VIII-IX MMI scale which means it can cause a seriousrisk of damage to the building.
