Physical distancing merupakan salah satu langkah pencegahan dan pengendalian infeksi virus Corona dengan menganjurkan orang sehat untuk membatasi kunjungan ke tempat ramai dan kontak langsung dengan orang lain. Kini, istilah physical distancing sudah diganti dengan physical distancing oleh pemerintah. Ketika menerapkan physical distancing, seseorang tidak diperkenankan untuk berjabat tangan serta menjaga jarak setidaknya 1 meter saat berinteraksi dengan orang lain, terutama dengan orang yang sedang sakit atau berisiko tinggi menderita COVID-19. Berdasarkan permasalahan ini diusulkan ide pembuatan suatu prototipe alat yang digunakan untuk penerapan physical distancing, untuk masyarakat yang terpaksa untuk keluar rumah karena keperluan mendesak seperi belanja kebutuhan pokok dipusat-pusat perbelanjaan ataupun berada pada suatu pusat keramaian lain seperti ditransportasi umum dan lain sebagainya. Orang-orang seperti ini memiliki resiko tinggi untuk tertular virus jika tidak berhati-hati. Dengan adanya prototipe alat ini harapkan masyarakat lebih memperhatikan dan menerapkan Physical Distancing, dikarenakan alat ini dapat mendeteksi obyek lain yang berdekatan dan memberikan sinyal berupa bunyi, dan didukung dengan sistem IoT (Internet of Things) sehingga mempermudah pengguna dalam memonitoring jarak dan lokasi kapanpun dan dimanapun. Selain itu mitigasi di masa pademi ini sangat penting seperti sosialisasi dan pemberian bantuan edukasi sangatlah penting. Sampai tahap pelaporan kemajuan ini, pengabdian masyarakat telah berjalan sesuai dengan jadwal. Prototipe gelang social distancing telah dibuat dan dilakukan pengujian. Gelang menunjukkan fungsi sesuai dengan spesifikasi yang diinginkan yaitu mampu mendeteksi keberadaan orang di sekita dengan jarak tertentu, mengirimkan posisi pengguna saat ini, dan dapat dilakukan pemantauan pengguna melalui aplikasi android.

Each production requires a system monitoring, so efficiency that the desired and productivity can be achieved and monitored in real time. This system is needed in the type of press machine production which is mainly influenced by based production lead time. The monitoring process is one of the factors that influences the time of production and manufacturing. Conventionally, the system is monitoring carried out manually by the operator on a piece of paper. This method tends to create errors and quite a long time. This paper aims to overcome the problems that occur by creating a system that is able to record and monitor the machine automatically. The solution is made by utilizing a sensor limit switch, infrared, pressure transmitter and Wi-Fi network based on Web Interface that is connected to the Firebase real time database. Equipped with PID control using the Ziegler Nichols 1 method to stabilize wind pressure on the system. Monitoring devices can be accessed on PCs, laptops, smartphones, connected to the internet, equipped with user-level operators, management, or engineers so that they can be used easily. All production data for each press is collected in a database. The data will be processed by the system to produce a value OEE machine. All data will be displayed on the Web Interface in real-time. The system output is the actual production, value OEE and wind pressure control. The test results show the system is running well, with 2s delay time and data accuracy of ± 0.2%.

The Pb-Zn mineralization in the Cho Don - Cho Dien ore districts often occurs in 2 types: (1)oxidized ore near to the surface and (2) sulfide ore at deeper section. Based on microscopic observations,sulfide ores can be divided into sphalerite-galena-pyrite and/or galena-sphalerite mineralization types. Toexamine the geochemical features of the Pb-Zn ores, SEM-EDX and ICP-MS analytical methods wereperformed in this study. Previous δ34S data of Pb-Zn concentrates, and sulfide minerals from variousdeposits suggest that the Pb-Zn ore-forming fluids might be related to the felsic-granitic magmaticactivities rather than a genesis of stratiform type. Geochemical data show that the major, minor, and traceelement compositions of lead-zinc ores have wide ranges of variation even in each deposit. The sulfideores are generally higher in economic components than those in the oxidized ores. The positivecorrelations between Pb-Ag can be found in the entire dataset, whereas excellent Zn-Cd correlation canonly be observed from Cho Don ore samples. Apart from the principal components (Pb and Zn), the oresalso contain other accompanying elements that supply high-technological manufacturing industries. Ofwhich As, Cu, Ag, Sb, and Cd could be potential by-products and can be extracted during smelting Pb/Znconcentrate processes, and need more detailed studies for every deposit.

Assessing the tendency of suspended sediment concentration (SSC) in the river watershedsenables a better understanding of the hydromorphological properties of its basins and the associatedprocesses. In addition, analyzing this trend is essential to address several important issues such as erosion,water pollution, human health risks, etc. Therefore, it is critical to determine a proper method to quantifyspatio-temporal variability in SSC. In recent years, remote sensing and GIS technologies are being widelyapplied to support scientists, researchers, and environmental resource investigators to quickly andsynchronously capture information on a large scale. The combination of remote sensing and GIS data willbecome the reliable and timely updated data source for the managers, researchers on many fields. Thereare several tools, software, algorithms being used in extracting information from satellites and support forthe analysis, image interpretation, data collection. The information from satellite images related to waterresources includes vegetational cover, flooding events on a large scale, rain forecast, populationdistribution, forest fire, landslide movements, sedimentation, etc., and especially information on waterquality, sediment concentration. This paper presents the initial result from LANDSAT satellite imageinterpretation to investigate the amount of sediment carried downstream of the Ba river basin.

Vietnam is an Asian country with hot and humid tropical climate throughout the year. Forestsaccount for more than 40% of the total land area and have a very rich and diverse vegetation.Monitoring the changes in the vegetation cover is obviously important yet challenging, considering suchlarge varying areas and climatic conditions. A traditional remote sensing technique to monitor thevegetation cover involves the use of optical satellite images. However, in presence of the cloud cover,the analyses done using optical satellite image are not reliable. In such a scenario, radar images are auseful alternative due to the ability of radar pulses in penetrating through the clouds, regardless of day ornight. In this study, we have used multi temporal C band satellite images to monitor vegetation coverchanges for an area in Dau Tieng and Ben Cat districts of Binh Duong province, Mekong Delta,Vietnam. With a collection of 46 images between March 2015 and February 2017, the changes of fiveland cover types including vegetation loss and replanting in 2017 were analyzed by selecting two cases,using 9 images in the dry season of 3 years 2015, 2016 and 2017 and using all of 46 images to conductRandom Forest classifier with 100, 200, 300 and 500 trees respectively. The result in which the modelwith nine images and 300 trees gave the best accuracy with an overall accuracy of 98.4% and a Kappaof 0.97. The results demonstrated that using VH polarization, Sentinel-1 gives quite a good accuracy forvegetation cover change. Therefore, Sentinel-1 can also be used to generate reliable land cover mapssuitable for different applications.
