Abstract

The purpose of this study was to determine the amount of water storage obtained from rainwater collected through the roof of the building and the monthly water needs at the University of Papua (Unipa) Manokwari Campus. The results showed that the input of rainwater per year was 3.54 times more than the water usage on campus. All buildings on the Unipa Manokwari campus had a water surplus per month, except for the Faculty of Economics and Business building which had a water deficit from October to December. Buildings with a water surplus can act as buffers for buildings with a water deficit.

Abstract

Has happen earthquake earth tectonics with magnitude 6.8 SR in Regency South Manokwari , West Papua Province on April 21, 2012. Purpose from study This is compare four decay models earthquake continuation namely the Omori , Mogi I, Mogi II and models Utsu to the earthquake data obtained from BMKG. Model with the smallest Root Means Square Error was the best earthquake decay model. Results matching curve shown the Mogi I and Utsu more suitable with earthquake decay data. Model of Mogi I and Utsu had mempredicted aftershocks for 15 days. Keyword: earthquake decay, aftershocks, Omori, Mogi I, Mogi II, Utsu
