WorldView-2 Satellite Image Classification using U-Net Deep Learning Model

Land cover maps are important documents for local governments to perform urban planning and management. A field survey using measuring instruments can produce an accurate land cover map. However, this method is time-consuming, expensive, and labor-intensive. A number of researchers have proposed using remote sensing, which generates land cover maps using an optical satellite image with various statistical classification procedures. Recently, artificial intelligence (AI) technology, such as deep learning, has been used in multiple fields, including satellite image classification, with satisfactory results. In this study, a WorldView-2 image of Terangun in Aceh Province, which was acquired on Aug 2, 2016, was classified using a commonly used deep-learning-based classification, namely, U-net. There were eight classes used in the experiment: building, road, open land (such as green open space, bare land, grass, or low vegetation), river, farm, field, aquaculture pond, and garden. For comparison, three classification methods: maximum-likelihood, random forest, and support vector machine, were performed compared to U-Net. A land cover map provided by the government was used as a reference to evaluate the accuracy of land cover maps generated using two classification methods. The results with 100 randomly selected pixels revealed that U-Net was able to obtain a 72% and 0.585 for overall and kappa accuracy, respectively; whereas, overall accuracy and kappa accuracy for the maximum likelihood, random forest and support vector machine methods were  49% and 0.148; 59% and 0.392; and 67% and 0. 511; respectively. Therefore, U-Net outperformed those three of classification methods in classifying the image. &nbsp

Kekuasaan Perspektif Politik Islam

Sebagai hasil dari penganalisaan tentang kekuasaan dalam politik Islam diketahui bahwa politik atau siyasah dalam pandangan Islam tidak hanya sebatas kebijakan-kebijakan dalam institusi terkecil sekalipun seperti rumah tangga. Politik atau siyasah adalah cara mengatur urusan kehidupan bersama untuk mencapai kesejahteraan dunia dan akhirat. Ia muncul dalam dunia domestic maupun publik, kultural, maupun struktural, personal dan komunal. Meski dalam perkembangannya, politik memiliki penyempitan makna menjadi istilah politik praktis, politik structural, perebutan kekuasaan untuk kepentingan diri atau sebagian orang dan sesaat, bukan untuk kepentingan masyarakat luas dan masa depan yang masih panjang. Kekuasaan yang sejalan dengan politik Islam adalah kekuasaan yang yang seperti dicontohkan Rasulullah saw. dalam kepemimpinannya. Kekuasaan itu sendiri terbagi tiga, yaitu kekuasaan legislatif, kekuasaan eksekutif, dan kekuasaan yudikatif. Hal ini memberikan gambaran bahwa pemerintah atau pemimpin yang menjadi penguasa bukanlah penguasa tunggal. Tetapi, dibantu oleh beberapa ahli dalam bidangnya masing-masing, agar kekuasaan yang muncul kemudian bukanlah kekuasaan yang bersifat dictator dan sewenang-wenang. Islam adalah agama rahmat, yang telah mengajarkan tata cara berpolitik yang islami, yaitu dengan tetap merujuk kepada Al-Qur‟an dan sunnah Rasulullah saw. Oleh karena itu, bagi pemimpin di belahan bumi manapun, Rasulullah saw. merupakan panutan dan teladan yang paling sempurna

Permasalahan pada skripsi ini yaitu: Bagaimana Perspektif Hukum islam terkait izin Poligami bagi PNS Pengadilan Agama Makassar. Permasalahan adalah: 1)Bagaimana pertimbangan hakim pengadilan agama Makassar dalam memutuskan izin poligami bagi PNS, 2)Bagaimana Pandangan Hukum Islam Terhadap Izin Poligami PNS di Pengadilan Agama Makassar. Penelitian adalah penelitian lapangan. Penelitian bermaksud menggambarkan objek penelitian saat sekarang, yaitu tentang izin poligami bagi PNS di pengadilan agama makassar perspektif hukum islam. Hasil penelitian adalah bahwa dalam pertimbangan hakim terkait perkara izin poligami PNS diterima karena pemohon memenuhi syarat yang diatur dalam PP Nomor 45 Tahun 1990 tentang Perubahan PP Nomor 10 Tahun 1983 tentang Izin Perkawinan dan Perceraian bagi PNS, selain itu memperoleh izin istri pertama. Secara islam poligami tidak dilarang selama adil. Hukum islam dalam memandang pertimbangan hakim dalam memutuskan izin PNS di pengadilan agama Makassar betul karena hakim tidak memutuskan hanya memperhatikan aturan pemerintah tetapi memperhatikan hukum islam. Peneliti berharap semoga menjadi pertimbangan hakim memutuskan izin poligami tidak hanya memperhatikan peraturan pemerintah dan undang-undang tapi juga memperhatikan hukum islam. Sehingga poligami tidak merusak norma-norma perkawinan. Teruntuk para akademisi Islam memberi pengetahuan poligami secara mendalam agar tidak terjadi masalah ketika itu terjadi.The problems in this thesis are: How is the perspective of Islamic law related to polygamy permits for civil servants of the Makassar Religious Court. The problems are: 1) What is the consideration of Makassar religious court judges in deciding polygamy permits for civil servants, 2) What are the views of Islamic law on PNS polygamy permits at the Makassar Religious Court. Research is field research. This study intends to describe the current object of research, namely about polygamy permits for civil servants at the Makassar religious court from the perspective of Islamic law. The results of the study were that in the judge's consideration regarding the case of polygamy permits for civil servants were accepted because the applicant met the requirements stipulated in Government Regulation No. 45 of 1990 concerning Amendments to Government Regulation No. 10 of 1983 concerning Marriage and Divorce Permits for Civil Servants, in addition to obtaining permission from the first wife. In Islam polygamy is not prohibited as long as it is fair. Islamic law in looking at the judge's considerations in deciding the permit of civil servants at the Makassar religious court is correct because the judge does not decide only to pay attention to government rules but pay attention to Islamic law. Researchers hope that the judge's consideration in deciding polygamy permits not only pays attention to government regulations and laws but also pays attention to Islamic law. So that polygamy does not destroy the norms of marriage. For Islamic academics who provide in-depth knowledge of polygamy so that there are no problems when it happens

Complete Feed Based on Fermented Sago Waste Against the Consumption and Digestion of Goat

A common method used to improve the nutritional quality of feed is by fermentation method.  The working principle is that fermentation activates the growth and metabolism of microorganism so that it can increase the digestibility of feed and produce the preferred aroma of livestock.  This study aims to find out the effect of giving fermented sago waste on the consumption and digestibility of goat and cattle. Two feed treatments were tested on 12 goats.  The results showed that the consumption and digestibility value of Dry Matter (DM) and Crude Protein (CP) showed no noticeable difference in goat cattle. The study concluded that complete feed-based fermented sago waste did not affect the consumption and digestibility of CP and DM of goat. Keywords: Sago waste, completed feed, consumption, digestion, dry matter, crude protei

Characteristics Of Cogon Grass Fibre Reinforced Thermoplastic Cassava Starch Biocomposite: Water Absorption And Physical Properties

The aim of this study is to investigate the characteristic of thermoplastic cassava starch (TPCS) composites containing cogon grass fiber (CGF) in the range of 1, 3, and 5 wt. %. Initially, the mixture of TPCS and CGF are prepared by pre-mixing using a high-speed mixer at 3000 rpm for 12 min. Then, the thermoplastic composites were pressed at 160°C for 35 min by using a compression molding machine. The composites were characterized for its moisture content, water absorption, thickness swelling and water solubility characteristics. Inclusion of 5 wt. % loading had significantly reduced the thickness swelling and water solubility of the biocomposites by 5.38% and 7.82%, respectively, compared with the neat TPCS. The moisture content and water absorption of the composites did not show significant changes following the addition of CGF. Overall, the incorporation of CGF into TPCS has enhanced the functional properties of the composites for short-life product applications

How land use/land cover changes can affect water, flooding and sedimentation in a tropical watershed: a case study using distributed modeling in the Upper Citarum watershed, Indonesia

[EN] Human activity has produced severe LULC changes within the Upper Citarum watershed and these changes are predicted to continue in the future. With an increase in population parallel to a 141% increment in urban areas, a reduction of rice fields and the replacement of forests with cultivations have been found in the past. Accordingly, LCM model was used to forecast the LULC in 2029. A distributed model called TETIS was implemented in the Upper Citarum watershed to assess the impact of the different historical and future LULC scenarios on its water and sediment cycles. This model was calibrated and validated with different LULCs. For the implementation of the sediment sub-model, it was crucial to use the bathymetric information of the reservoir located at the catchment's outlet. Deforestation and urbanization have been shown to be the most influential factors affecting the alteration of the hydrological and sedimentological processes in the Upper Citarum watershed. The change of LULC decreases evapotranspiration and as a direct consequence, the water yield increased by 15% and 40% during the periods 1994-2014 and 2014-2029, respectively. These increments are caused by the rise of three components in the runoff: overland flow, interflow and base flow. Apart from that, these changes in LULC increased the area of non-tolerable erosion from 412 km(2) in 1994 to 499 km(2) in 2029. The mean sediment yield increased from 3.1 Mton -yr(-1) in the 1994 LULC scenario to 6.7 Mton-yr(-1) in the 2029 LULC scenario. An increment of this magnitude will be catastrophic for the operation of the Saguling Dam.This study was partially funded by the Spanish Ministry of Economy and Competitiveness through the research projects TETISMED (CGL2014-58,127-C3-3-R) and TETISCHANGE (RTI2018-093717-B-I00).
