No full textCurrently the progress of Information and Communication Technology has been adapted by various government agencies or private, one of the technology that can be used is web, government have used this technology for e-government. The Office of Industry, Trade and SME of Kota Pagar Alam that runs the Market through the Technical Implementation Unit of the Service gives the right to rent at Pasar Dempo Pagar Alam. During this time if there is an empty kiosk, prospective tenants come to the clerk for confirmation and lease submission process. To simplify the management and lease submission process, an application is needed that can facilitate the officer and prospective tenants to interact, while the application will be built is web-based. The purpose of this study design application in the sense of translating the results of the analysis into the form of software packages later Create the system or improve the existing system. To make the proposed system the author uses the steps of Customer Communication, planning, modeling, construction and deployment
A Sustainable Campus for Higher Education Institutions in the US
No full textThe green and sustainable campus as a concept is not something new to the US However, well organized and coherent activities to effectively "green" campues are not that common, and efforts are minor in comparison tothe potential of these universities (green and tompson, 2005)This poster was presented by Alam, Md Imtiajul A Sustainable Campus for Higher Education Institutions in the US. at the 5th Graduate and Professional Student Research Conference April 11, 2018, Memorial Union, Iowa State University, Ames, Iowa.

North-East Interface: Ethnographic Reading of the Hidden Land
No full textThis paper is an attempt to explore the general and demographic overview of North East India pertaining to ethnicity and ethnic set up. There is no other part in the country which is more diverse to us than the entire North East and it’s not some small corners of India, it spreads over 2.6 lakh square kilometres, larger than hundred sixteen nations of the world and inhabited by more than two hundred fascinating communities largely originated from Caucasoid, Mongoloids and Australoids. They also show an ethno-cultural bridging with the neighbouring countries of South East Asia. This region has more than four hundred languages and dialects representing each and every ethnic community with Assamese as a ‘lingua-franca’. North East is also home to more than seventy five percent languages belonging to the four language families i.e. - Indo-Aryan, Tibeto-Burman, Austro-Asiatic and Dravidian. To find four language families in such a place is really incredible and could be well regarded as a linguistic area. The phenomenal rise and growth of multi-ethnic identities in this kaleidoscopic land presents the picture of the possibilities of exploring the human scrapes, its culture, demography and above all the ‘ethnic way of life’ (Biswas and Suklabaidya,) with the view of imagining an inside of thinking. It further tries to widen the socio-political and philosophical imaginations of the ‘nation from below’ (Biswas and Suklabaidya, 231). Also ethnography sets an agenda to explore the cultural position of ethnic groups lost in the universalist mapping of humanity
Teacher Candidates' opinions about Augmented Reality(AR) as a supplemental educational tool
No full textThis poster was presented by Alam, I., Teacher Candidates' opinions about Augmented Reality(AR) as a supplemental educational tool. Presented at 10th Annual Graduate and Professional Student Conference, held at Memorial Union, Ames, IA, April 6 2022. Posted with permission.In recent years, augmented reality (AR) technology has been widely proposed as innovative technology. AR technology superimposes digitally simulated information on the physical environment, which can be a unique element for learning experiences. Despite the potential of AR, there has been relatively little integration of AR into the
classroom. The purpose of this pilot study is to examine the acceptance and intentional use of AR technology by teacher candidates and their opinions of AR as a supplemental educational tool. The study has utilized a phenomenological design that is comprised of System Usability Scale survey and interview questions. Based on the participants' answers, research data has been analyzed and discussed
Lingkungan Hidup Dan Pengelolaan Sumberdaya Alam Dalam Perspektif Islam
No full textThis paper discusses the environment and natural resource management in an Islamic perspective from the author\u27s perspective based on the limited amount of Islamic literature that the author knows. The discussion starts from defining the environment, analyzing human behavior towards the environment, human behavior and environmental destruction, human efforts in environmental conservation. It also discussed ethics and the environment, and finally religious views, especially Islam on the environment and natural resource management as well as environmental conservation orders, both recorded in the holy book as well as in history and hadith. Information was collected based on a literature review of research results and previous records as well as the results of observations of the environment itself.Tulisan ini membahas tentang lingkungan dan pengelolaan sumber daya alam dalam perspektif Islam dari kacamata penulis berdasarkan sejumlah terbatas literatur Islam yang penulis ketahui. Pembahasan dimulai dari pendefinisian lingkungan, analisis perilaku manusia terhadap lingkungan, perilaku manusia dan pengrusakan lingkungan, usaha manusia dalam pelestarian lingkungan hidup. Dibahas juga tentang etika dan lingkungan hidup, dan terakhir pandangan agama, khususnya Islam terhadap lingkungan hidup dan pengelolaan sumberdaya alam serta perintah pelestarian lingkungan, baik yang tercatat dalam kitab suci maupun dalam riwayat dan hadits. Informasi dikumpulkan berdasarkan kajian literatur hasil penelitian dan catatan sebelumnya serta hasil pengamtan terhadap lingkungan itu sendiri

No full textThe past, present, and future of piezoelectric fluoropolymers: Towards efficient and robust wearable nanogenerators
No full textPolyvinylidene difluoride (PVDF) derivatives in metal/PVDF/metal (MPM) sandwich structures have been studied extensively since 1969. Cousin copolymers of the same family have been discovered with fascinating piezoelectric, pyroelectric, electrocaloric, and ferroelectric properties. Solution processing, flexibility, lightweight, and thermal stability make this class of materials complementary to inorganics. Thus, PVDF based polymers potentially compete with inorganic materials for a broad range of technologies such as energy generators, loudspeakers, coolers, and memories. However, the stable non-electroactive α-phase and hydrophobic nature of PVDF are the main barriers for developoing high performing and robust MPM devices in electronic applications. In this review, we present an up-to-date overview on different methods to induce the electroactive β-phase and improve the adhesion strength with metals to ensure robust and durable MPM devices. We go through advantages and disadvantages of several methods and pinpoint future opportunities in this research area. A special attention is paid to wearable piezoelectric nanogenerators for energy harvesting from human body motion, where flexible PVDF derivatives are compared with rigid piezoelectric ceramics. While the piezoelectric coefficient of PVDF (d33 ~ 24–34 pm/V) is one order lower than ceramic materials, novel co-polymers of PVDF display d33 > 1000 pm/V upon bias. This shows promise to bring piezoelectrics to flexible and large-area applications such as smart textiles. We also discussed challenges to improve wearability, such as light weight, breathability, and flexibility.Funding Agencies|Linköpings Universitet, LiU, (2009-00971); Knut och Alice Wallenbergs Stiftelse, (KAW 2022-0383)</p
