<span>It has been done a research about separation of regional-residual anomaly in Gravity method. <span>This research compares the result of three methods i.e. moving average method, polynomial <span>method, and inversion method. The computer program is created using a computer programming <span>Matlab 7. From three methods that have been made, the separation results are compared with<br /><span>results of separation by using Upward Continuation method. From the results of these <span>comparisons will be available an excellent program of regional-residual anomali separation. The <span>results show that in polynomial method of the order 4 obtained similar contour to the separation <span>by Upward Continuation Software. So that the output of this separation will be treated again <span>with Grav2DC software. The output of this software is the density of rock Grav2DC of the study<br /><span>area. Processing results obtained the minimum error of 1.85% for the separation by polynomial <span>method, while for the method of Upward Continuation obtained minimum error of 2.22%. The <span>results obtained show that the separation of regional-residual anomali by polynomial method is <span>similar to separation by Upward Continuation method.</span></span></span></span></span></span></span></span></span></span></span></span><br /></span>
<span>It has been conducted a research about sea level rise (SLR) in surrounding Jawa island by using <span>satellite altimetry data Topex/Poseidon, Jason-1 dan Jason-2 for period 2000 <span>– <span>2010. Satellite <span>altimetry is satellite which specially design for measuring dynamics of sea water. Those <span>satellite lauched firstly in 1992 incorporation between <span><em>National Aeronautics and Space </em><span><em>Administration </em><span>(<span><em>NASA</em><span>) dan European Space Agency (ESA). There are six locations for <span>measuring SLR i.e. Jakarta, Semarang, Surabaya, Pangandaran, Jogjakarta dan Prigi. We chose<br /><span>locations based on alongtrack of satellite and near the big cities in Jawa island with dimension <span>area around 0.5<span>o<span>x0.5<span>o <span>degrees. We found SLR rate for Jakarta (2.5 ± 0.24 mm/yr), Semarang <span>(2.16 ± 0.20 mm/yr), Surabaya (2.72 ± 0.19 mm/yr), Pangandaran (0.71 ± 0.33 mm/yr), <span>Jogjakarta (0.91 ± 0.38 mm/yr) and Prigi (1.3 ± 0.38 mm/yr). The average SLR rate for North <span>coast is (2.46 ± 0.21 mm/yr) and for South coast (0.97 ± 0.36 mm/yr). This results are well<br /><span>correlated with data from tide gauge stations.</span></span></span></span></span></span></span></span></span></span></span><br /></span></span></span></span></span></span></span></span></span></span></span>
Telah dilakukan upaya dalam rangka optimalisasi penjualan produk – produk hasil karya masyarakat Wonorejo Kecamatan Paolokarto Kabupaten Sukoharjo. Bulan Maret tahun 2020 merupakan awal terjadinya pandemi virus Corona sehingga penjualan produk secara <em>offline </em>hampir terhenti karena masyarakat diwajibkan tetap berada di rumah. Sebuah upaya dilakukan agar masyarakat tetap dapat memperoleh pendapatan, sehingga dihasilkan layanan berbasis media sosial <em>ecommerce</em> untuk menampung berbagai produk masyarakat, hasilnya berupa akun facebook Produk Unggulan Wonorejo untuk proses jual beli, proses awal adalah sosialisasi akun tersebut, akun yang dibuat sejak 12 April 2020 telah memiliki teman 2761 dan juga group jual Produk Unggulan Wonorejo yang memiliki anggota 510 Anggota. Sampai saat ini telah ada 1670 postingan jual beli, banyak terjadi transaksi jual beli untuk produk – produk hasil masyarakat, dengan adanya akun dan group ini membantu masyarakat dalam menjual produknya di masa pandemi covid 19 terlihat dari hasil jajak pendapat dimana selama 2 bulan hasilnya adalah 80 % menyatakan bermanfaat, 19 % cukup bermanfaat dan 1 % tidak bermanfaat
INITIATING ENTREPRENEURIAL SKILLS THROUGH THE INTRODUCTION OF E-COMMERCE FOR ORPHANS OF THE MUHAMMADIYAH ORPHANAGE IN BLIMBING SUKOHARJO. Efforts to improve skills and the cultivation of entrepreneurial spirit have been carried out at the Orphanage PKU Muhammadiyah Cabang Blimbing. This institution is home to 20 orphans located in Wonorejo, Polokarto, Sukoharjo. Wonorejo village is a convection village where most of the population work as convection producers, which in the sale of their clothes still use conventional methods, which are sold in stores and in markets. The pattern of mutually beneficial cooperation between convection entrepreneurs and orphans is initiated by technopreneurship activities namely by selling convection through online stores.
