These bacteria have many virulence factors that play an important role in the pathogenicity of infection and antibiotic resistance. Pili protein Klebsiella pneumoniae with 38.6 kDa as one of the virulence factors, that have roles as hemagglutinin dan adhesin protein so potentially as a vaccine candidate. This research aimed to immunodetection pili protein 38.6 kDa using Western Blot.  Western Blot was used to detect that protein with specific primary antibodies. These antibodies are obtained from mice serum-induced intraperitoneally with Pili protein 38.6 kDa Klebsiella pneumoniae. Protein bands that appear on the membrane of Western Blot results are proteins with a molecular weight of 85.6 kDa, 65.5 kDa, 46.9 kDa, and 29.4 kDa. This study concludes that Pili protein 38.6 kDa Klebsiella pneumoniae as the target protein does not appear in the Western Blot result.Abstrak: Klebsiella pneumoniae adalah patogen yang menyebabkan infeksi di komunitas maupun rumah sakit.

Analysis of the distribution of geothermal manifestations can be done with remote sensing techniques and direct measurement. Furthermore, information on geomorphological conditions, surface temperature, and geothermal potential distribution can be known based on the density value on the FFD (Fault Fracture Density) map and satellite image processing results. Data processing uses ArcGIS and ENVI software concerning geothermal manifestations. The analysis was performed by converting DEMNAS data to a hillshade for drawing straightness structures related to the fault. Image data processing to obtain vegetation density (NDVI), hydrological state (NDWI), and surface temperature distribution (LST). NDWI values are inversely proportional to NDVI. The LST value depends on the density of the vegetation; the higher the vegetation density, the lower the surface temperature. The FFD map is divided into three levels i.e. low (0-0.17 km/km2), moderate (0.17-0.47 km/km2) and high (0.47-1.2 km/km2). The distribution of geothermal potential is at medium and high-density levels, including the Silih Nara, Wih Pesam, and Pintu Rime Gayo areas. The straightness direction is in the north-south and southeast-northwest positions. Based on the NDVI, NDWI, and LST map analysis results, geothermal energy distribution has a rare to moderate vegetation density with surface temperatures ranging from 25.8oC-39.6oC.

The Covid-19 pandemic has accelerated a cultural, ethical, and normative change in people's behavior. The potential for social change resulting from the emergence or advancement of information and technology is significant. The rise of social media, which has now become a common form of communication, is unavoidable. Digital communication through a variety of websites to obtain information will leave digital traces. The concept of a digital trail certainly reaffirms what has previously been written in Al-Qur'an, Surah Yasin: 65. This verse is relevant to digital multi-hop tracks that outline human actions and behavior to the swipe of their fingers. The verse is translated through the use of a digital trail that is connected to internet access. This library research study uses the source triangulation method to analyse exploratory qualitative content. The study's findings indicate a correlation between the digital trail and Surah Yasin 65, demonstrating that current digital technology proves that the Qur'an's nash or verses are consistent with the unquestionable assumption of human rationality. It also emphasizes the importance of being cautious and responsible when using digital platforms.Abstrak: Tren peningkatan penggunaan internet memberikan pengaruh besar terhadap perilaku masyarakat.

However, the appropriate concentration should be well studied to obtain the optimum concentration to improve the sperm quality and quantity. The present research tried to provide information on how lemon could improve the sperm quality by designing a true experimental using a series concentration of lemon extract (25%, 50% and 75 % concentrations) given to the male mice (Mus musculus). The investigation was made by giving the lemon treatment three times a day for 5 weeks. To investigate the effect of lemon extract, the mice sperm were taken from the epididymis and observed using a multimedia microscope and counted using Neubauer’s counting rooms, while motility and morphology were observed using object-glass. The result showed that the high concentration of lemon could not provide the greatest improvement of sperm quality and quantity. The optimum condition was seen in 25% of lemon extract, where the increase of lemon concentration suppressed the lemon improvement effect, which reduced the sperm quality and quantity. However, the improvement was still made if the result was compared to control, meaning consuming lemon was better than consuming any lemon treatment. The result was in accordance with quality improvement of sperm, where 25% of lemon concentration treatment provided the highest average motility and normal morphology of sperm. However, the high concentration of lemon extract (50% and 75% of lemon concentrations) provided a lower effect due to the adverse effect.

Modernity concept to visualize the simple form in a mosque is relevant, which would help the worshippers to be more solemn. Office buildings, mainly located in Aceh, known as Serambi Mekkah, are required to provide a mosque in the office environment. Since its concept transforms from traditional style to modern style, the mosque in the office area is designed in modernity. The study purposes of enabling climate-responsive principles in mosque design for achieving indoor thermal comfort. Even though without available power support. The design method approached problem-solving by creating the building friendly to the environment and achieving indoor thermal comfort. This study used trial and error through modeling appropriate to climate-responsiveness mosque design in the office area. Furthermore, this study would be continued in complex buildings, namely schools and offices, promoting environmentally-friendly to be applied in building design. Abstrak: Masjid adalah tempat ibadah bagi umat Islam. Konsep modernitas untuk memvisualisasikan bentuk sederhana di masjid adalah relevan, yang akan membantu jamaah untuk lebih khusyuk. Gedung perkantoran khususnya yang berada di Aceh yang dikenal dengan Serambi Mekkah wajib menyediakan mushola di lingkungan kantor. Karena konsepnya bertransformasi dari gaya tradisional ke gaya modern, masjid di area perkantoran juga didesain dengan gaya modern. Tujuan studi ini adalah untuk mengaktifkan prinsip responsif iklim dalam desain masjid untuk mencapai kenyamanan termal dalam ruangan meskipun tanpa dukungan daya yang tersedia. Metode desain pada studi ini menggunakanpendekatan pemecahan masalah untuk menciptakan bangunan ramah lingkungan dan mencapai kenyamanan termal dalam ruangan. Penelitian ini menggunakan metode trial and error melalui pemodelan yang sesuai dengan desain masjid yang responsif terhadap iklim di kawasan perkantoran. Selanjutnya studi ini akan dilanjutkan penerapannya pada bangunan kompleks seperti sekolah dan perkantoran untuk mempromosikan desain bangunan ramah lingkungan.","PeriodicalId":11527,"journal":{"name":"Elkawnie","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76373323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
