Reliability of distribution networks is a factor that greatly affects customers as consumers of electricity. Analyzing and calculating the reliability of distribution networks are determined by the reliability index including SAIFI, SAIDI, CAIDI, and ASAI. On the other hand, smartphone technology is growing rapidly with a variety of applications to help simplify and accelerate human work in several fields of work. This paper delivers the design of an Android-phone-based analytic tool for distribution system reliability index measurement by developing it on Android application software. This application is named KALINDA, stands for Kalkulator Indeks Keandalan (Reliability Index Calculator), and created by using Android Studio IDE. We compare the data result between KALINDA calculations and manual calculations. The results obtained from the KALINDA application are declared to be valid accurate.
Pandemi Covid-19 telah berlangsung hampir satu tahun dan belum menunjukkan tanda- tanda penurunan kasus, bahkan semakin meningkat. Penularan virus corona melalui droplet bisa langsung dari orang ke orang ataupun melalui media benda padat yang telah terkontaminasi virus. Oleh karena itu masyarakat diminta untuk selalu mencuci tangan, menjaga jarak dan memakai masker dalam setiap aktivitas. Untuk benda-benda yang mungkin menjadi media penularan bisa dilakukan desinfeksi dengan cairan disinfektan.
Masyarakat telah mengenal cairan desinfektan dan telah jamak digunakan dalam kegiatan sehari- hari. Cara lain untuk melakukan desinfeksi adalah dengan penyinaran ultra violet (UV) terhadap benda-benda yang mungkin terkontaminasi. Saat ini telah banyak beredar peralatan desinfeksi UV yang bisa dibeli di toko-toko namun harga jualnya masih sangat tinggi, mencapai jutaan rupiah. Harga ini jelas tidak terjangkau oleh masyarakat bawah.
Peralatan desinfeksi menggunakan paparan sinar UV sebenarnya bisa dibuat sendiri dengan biaya yang murah. Meskipun demikian banyak hal yang perlu disadari dalam penggunaan sinar UV karena mengandung bahaya bagi kulit atau mata yang terpapar langsung. Tujuan Program Pengabdian kepada Masyarakat Program Kemitraan Masyarakat (PKM) ini adalah memberikan pengetahuan kepada masyarakat akan cara lain dalam melakukan desinfeksi benda yang mungkin terpapar virus, serta membantu masyarakat untuk membuat UV chamber dan menghindari resiko yang mungkin terjadi.
The development of communication technology in Indonesia is currently growing, one of which is cellular telecommunications technology. Cellular communication technology developed from the first generation to the present time has entered the 4th generation known as 4G LTE. The writing of this final project discusses the analysis and optimization of the 4G LTE network of Telkomsel seluer operators in Jombang, East Java. Measurements were made using the drive test method to test the 4G LTE network in the inner area of Jombang district. This testing is done to check the network in the inner area whether it is optimal in providing network to customers. This drive test uses a nemo handy device and to analyze drive test results using a nemo analyzer. The results measured when doing a drive test are RSRP, SNR, and throughput parameters. The results of the RSRP parameter get 95% of the total sample RSRP values -100 dBm to 0 dBm. The SNR parameter gets 94% of the total sample which has a value of 0 dB to 25 dB. The throughput parameter gets 95% of the total sample value above 1Mbps. After a drive test and analysis there are 4 areas that need to be optimized because in terms of quality or SNR and the data speed or throughput is below the standards applied by the operator.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
