Abstract

The development of Governor's Office of West Papua Province has cause change forest land area become using other land on the surrounding area, so that it has cause increasing the runoff surface wide and the coefficient of runoff . Objective of this study was for know development of the runoff surface wide and the average runoff coefficient with using satelitte image since 2010 to 2023. Results observation of satellite image that the runoff surface wide increase to 99.55 ha (56.25%) and average runoff coefficient increases from 0.32 to 0.56.

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
