Abstract. 65.5:8.5 is the consumption ratio of fossil energy and clean energy in Indonesia with 389.43 million metric tons carbon emission in 2010 (WDI & GDF 2013). It is an irony because Indonesia is one of the lungs of the world and Indonesia has so many alternative energies such as sea wave energy that has zero emission. Indonesia needs to develop this kind of energy because Indonesia has great length of shore and the one of the greatest shore for sea wave energy is Gunungkidul’s shore. That potential place needs to be developed by quick and right technique to know suitability of on shore sea wave energy power station placement. Remote sensing technique that integrated with Geographic Information System is an effective way to get information of sea wave energy placement suitability. Landsat Satellite image 30 m spatial resolution used to find out shore morphology. Bathymetric map can give sea water depth and shore tilt information by interpolate every height point. Shore slope data is used to identify the wave type of the shore. Wind data interpolation in every measure point gives information about wind speed and wind direction. Matching method is used against parameter of shore morphology, sea water depth, shore slope, wave type, wind speed, and wind direction as the early rating and basic of land suitability identification for onshore sea wave power station site selection. Land suitability level is divided to very suitable (S1), quite suitable (S2), marginal suitable (S3), and not suitable (N). Based from identification result with matching method could be known suitability level of onshore sea wave power station placement so that can produce optimal energy.

Abstract: Indonesia is 15^th strongest country in the world, and  1^st in South-east Asia with maritime power 17^th in the world (3^rd in South-east Asia) and air power 31^st in the world (3^rd in South-east Asia) (Global Fire Power). It is unfortunate because Indonesia is the biggest archipelago country with number of islands more than 17 thousand but doesn’t have optimal power of maritime and air that can weaken Indonesia itself. With quite little power of maritime and air Indonesia should have the right strategy spatially so that Indonesia can maintain all region from outside attack when maritime and air power still in development. Overlay method of Attack Map with analysis of attacks that have occurred is used to determine the right spatial defense strategy. Consideration parameters that are used are attacks-that-have-occurred direction, number of armada, strongest type of armada, number of near-country, presence of Indonesian important facility, and technology of the attacker. With remote sensing, bathymetric map, and topographic map, description of Indonesian relief will be known and can be utilized to determine every strategy in every region in Indonesia because every region has different characteristic of environment and geography so that it needs to make profound region study to determine the suitable defense strategy in every region. The result is attack prediction map with the suitable strategy spatially.

UAS was the END

Semoga semester ini bisa membawa kabar baik ya buat orang rumah.

aamiin :)

Welcome HOLIDAY~

Pasar Kangen Jogja

Hari ini selepas gue selesai UAS, seperti biasanya hal pertama yang gue lakukan setelah itu adalah jalan-jalan meenn!! Tujuan refreshing kali ini ke Taman Budaya Yogyakarta, tepatnya berkunjung ke Pasar Kangen Jogja yang menghadirkan kembali suasana tempo dulu khas Kota Gudeg. 

 
Karena pasar kangen menjanjikan suasana tempo dulu, so pasti hal pertama yang gue cari di sana adalah perangko. Berburu perangko, yuuuhhuuuu :D

Abstract

This time we indicate that Indonesia will suffers the crisis of energy. Indonesia has so much energy to solve that problem. There is a source of great energy that people seldom use this energy, sea wave energy. Indonesian shore has length about 81,000 km, but Indonesia doesn’t utilize it to make a sea wave power plant as commercial power plant yet. The sea wave power plant will be a great potential power source of Indonesia that can produce energy around 61 GW. On the other hand, sea wave energy is a really good eco-energy that has zero emission. Gunungkidul is a region in Yogyakarta that has a unique region characteristic and can be utilized for onshore sea wave power plant. Most of Gunungkidul’s shores are made by karst/limestone with steep slope of shore so the wave will grow bigger. We use scoring method, remote sensing and geographical information system application for choose the right place and thematic map overlay for serve the result. This research can be used as reference for sea wave power plant planning in Gunungkidul and can become the alternative energy for green living.
