Kota Pariaman tahun 2009 mengalami gempabumi dua kali dengan kekuatan gempa (Mw) 7,9 dan 6,2 (USGS, 2009). Dampak yang ditimbulkan terjadi korban jiwa meninggal 46 jiwa, luka berat 64 jiwa dan luka ringan 363 jiwa (BPK - RI 2010).Upaya yang dilakukan untuk meminimalisasi korban jiwa, pemerintah daerah membuat rute evakuasi menuju TES di lokasi yang aman. Lokasi penelitian berada di Desa Naras Satu, Desa Ampalu, Desa Kampung Baru, Desa Karan Aur, Desa Taluak, Desa Marabau dan Desa Pasir Sunur. Upaya yang dilakukan agar meminimalisasi korban bencana dengan mengevakuasi warga menuju TES dengan jarak tempuh 270 m yang dapat dicapai dalam waktu 6 menit. Proses analisis SIG menggunakan jaringan jalan (network analysis). Parameter yang digunakan adalah jaringan jalan dan sebaran rumah penduduk.Dari Hasil analisis SIG dapat diketahui usulan TES berjumlah 39 unit yang berada di Desa Naras Satu sejumlah 8 unit, Desa Ampalu 5 unit, Desa Kampung Baru 11 unit, Desa Karan Aur 7 unit, Desa Taluak 1 unit, Desa Marabau 4 unit dan Desa Pasir Sunur 3 unit. Kelayakan TES yang dapat menampung warga antara lain Kantor lama Walikota Pariaman Karan Aur, Mesjid Pasir Sunur, SDN 5 Marabau, SMPN2 Kampung Baru dan SDN 15 Ampalu.

This study aims to determine oceanographic characteristics such as tides, waves, and currents in Karimunjawa Coastal Waters during the 1st transitional season and to update the oceanographic database for spatial management evaluation in the region. The tidal characteristics were obtained from the least square method analysis using World Tide software based on Matlab programming language, while wave and current characteristics obtained from 2-dimensional numerical modeling using Mike 21 software on the flow model and spectral wave module. The primary data used were the significant wave height (Hs), wave peak period (Tp), and ocean current components (u and v velocity) on 13-26 May 2016 using the Sontex Argonaut XR type Acoustic Doppler Current Profiler (ADCP) equipment. Tide data were predicted for the Kemujan Islands station from 1-31 March 2020. Secondary data for additional numerical model input were obtained from ERA5-reanalysis in the form of Hs, Tp, u, and v wind velocity data for May 2020 with a temporal resolution of 20 minutes, while bathymetry data derived from GEBCO Satellite Derivated Bathymetry (SDB) data. The tide analysis results showed that Karimunjawa waters are a single daily mixed tidal type. The wave characteristic moves from east to west with high waves reached 0.9 meters and a peak period of 7 seconds. The eastern side of Karimunjawa Island, Kemujan Island, and the western area have a calmer wave. The current characteristic moves northeastward with a speed of 5-28 cm/s, which concludes that in several locations, such as the Menjangan Besar-Menjangan Kecil strait, the currents depend on the tidal conditions.

Healthy coral reefs depends on the quality of the waters , so that research and monitoring of water quality becomes important. This research attempt to asses marine waters quality at kaledupa island and it’ s surrounding waters on October and November 2014. 33 In-situ samples were collected using multiparameters tool purposively which are categorized into physical parameters (temperature, turbidity and clarity), and chemical parameters (DO, salinity and pH). Waters quality defined by STORET method based on Ministry of Living Environment decree number 115 year of 2003. Analysis geographically has been conducted to describe distribution of waters quality spatially. The result shows that Kaledupa waters has sustain slightly pollution, especially on DO, turbidity, temperature and salinity parameters which have deviated from standard values. The light pollution in Kaledupa waters is suspected caused by the entry of abundance organic matter and shallow bathymetry.
