<span lang="EN-US">Since the COVID-19 pandemic, automated liquid dispensers have been increasingly developed to assist transmission prevention. However, data availability of automatic liquid dispenser mechanism's technical characteristics is not yet widely available. This causes frequent over or under design in its development. Therefore, we specifically measure push and pull forces engineering characteristics generated by the automatic liquid dispenser mechanism. A wire mechanism-based automatic liquid dispenser apparatus was used to experiment. A load-cell sensor was used to detect the force that occurs from a servo motor controlled by a microcontroller. The force data (push and pull) will be sent directly to the database server cloud with a recording </span><span lang="EN-US">frequency of every second. Three types of fluid treatment levels are used i.e. water, liquid soap, and hand sanitizer gel. Three types of fluid volume treatment levels used were 50 ml, 150 ml, and 250 ml. Each treatment level combination is carried out at the servo motors rotation steps 180</span><span lang="EN-US">°</span><span lang="EN-US">, 150</span><span lang="EN-US">°</span><span lang="EN-US">, 120</span><span lang="EN-US">°</span><span lang="EN-US">, 90</span><span lang="EN-US">°</span><span lang="EN-US">, 60</span><span lang="EN-US">°</span><span lang="EN-US">, and 30</span><span lang="EN-US">°</span><span lang="EN-US">. The results show that no significant differences were found in maximal forces required to release the water, liquid soap, and hand-sanitizer gel. It is also known that the volume of the fluid has a very significant effect on the amount of push and pull forces generated.</span>

Cluster Server

A database server called the Database Management System (DBMS) that relates tables in a database is called the Relational Database Management System (RDBMS). DBMS/RDBMS is a computer program that provides data services for computers or other computer programs. One of the RDBMS type database server (hereinafter referred to as a database server) is MariaDB. The database server is in charge of managing and providing data, so data must always be ready, fast presented, accurate, and safe, it cannot be damaged or even lost. One way to provide this data is to install several database servers using the concept of replication in the Multiple Server Database system. Replication in a cluster server database is a method of installing several database server nodes that allow between node servers to copy each other and distribute data from one node to another database server node, which then synchronizes data between server nodes to maintain data consistency. This study looks for the most optimal number of minimal database server nodes to provide accurate, fast and safe data on the MariaDB Cluster RDBMS. From the results of the replication test from the cluster server database, it can be concluded that the number of 3 (three) node servers can be known to always synchronize and consistency of data between server nodes, so there are 3 (three) nodes of minimum database node with MariaDB RDBMS.

Compared with other parts of the hand, the area beneath fingernails harbors the most microorganisms and is most difficult to clean. Artificial fingernails, which are usually long and polished, reportedly harbor higher microbial populations than natural nails. Hence, the efficacy of different hand washing methods for removing microbes from natural and artificial fingernails was evaluated. Strains of nonpathogenic Escherichia coli JM109 and feline calicivirus (FCV) strain F9 were used as bacterial and viral indicators, respectively. Volunteers with artificial or natural nails were artificially contaminated with ground beef containing E. coli JM109 or artificial feces containing FCV. Volunteers washed their hands with tap water, regular liquid soap, antibacterial liquid soap, alcohol-based hand sanitizer gel, regular liquid soap followed by alcohol gel, or regular liquid soap plus a nailbrush. The greatest reduction of inoculated microbial populations was obtained by washing with liquid soap plus a nailbrush, and the least reduction was obtained by rubbing hands with alcohol gel. Lower but not significantly different (P &gt; 0.05) reductions of E. coli and FCV counts were obtained from beneath artificial than from natural fingernails. However, significantly (P ≤ 0.05) higher E. coli and FCV counts were recovered from hands with artificial nails than from natural nails before and after hand washing. In addition, microbial cell numbers were correlated with fingernail length, with greater numbers beneath fingernails with longer nails. These results indicate that best practices for fingernail sanitation of food handlers are to maintain short fingernails and scrub fingernails with soap and a nailbrush when washing hands.

The community service activity was carried out with the partner of Karang Taruna Bimantara, as a youth organization located in kampung Kalikepiting Jaya VI, RT 5, RW 5, Kelurahan Pacarkembang, Kecamatan Tambaksari, Surabaya City. This activity was aimed at reviving this organization which has been inactive for a long time and empowering the youths in preventing the transmission of Covid-19. The activities offered were providing enlightenment about Covid-19, assistance in producing liquid soap, hand sanitizers and non-medical cloth masks which could be developed into productive economic businesses. The implementation of these activities also involved the organization of Family Welfare Education (Pendidikan Kesejahteraan Keluarga or PKK) which was an organization of mothers in this kampung.  The enlightenment were included Covid-19 and diseases transmitted by mosquitoes, their prevention and transmission. By producing the items than can be used to prevent transmission of Covid-19 followed by obedience to the health protocols, they could participate in preventing the transmission of Covid-19. In order to increase their knowledge on productive economy, the enlightenment on productive economy, marketing of goods and financial management of business, the enlightenment was also given. Hopefully the activities which can be developed into a productive economy business can increase the income of this kampung. The enlightenment provided pre-test and post-test. Comparison of both tests resulted in an insignificant increased in knowledge on both topics. More participants and more questions are recommended to improve the more significant scores of tests. The sales of liquid soap and hand sanitizer resulted in profit can be used to reproduce. Furthermore, more assistance is needed to develop a business into a productive economy.abstrakKegiatan pengabdian masyarakat ini dilaksanakan bersama mitra Karang Taruna Bimantara yang berada di kampung Kalikepiting Jaya VI, RT 5, RW 5, Kelurahan Pacarkembang, Kecamatan Tambaksari, Kota Surabaya. Kegiatan ini bertujuan untuk menghidupkan kembali organisasi yang sudah lama tidak aktif ini dan memberdayakan para pemuda dalam rangka pencegahan penularan Covid-19. Kegiatan yang ditawarkan antara lain adalah penyuluhan tentang Covid-19, bantuan pembuatan sabun cair, hand sanitizer dan masker kain non medis yang dapat dikembangkan menjadi usaha ekonomi produktif. Pelaksanaan kegiatan ini juga melibatkan ibu-ibu yang tergabung dalam organisasi PKK (Pendidikan Kesejahteraan Keluarga) yang merupakan wadah ibu-ibu di kampung ini. Penyuluhan yang diberikan adalah mengenai Covid-19 dan penyakit yang ditularkan oleh nyamuk, pencegahan dan penularannya.

ABSTRACT Disinfection is an essential measure for interrupting human norovirus (HuNoV) transmission, but it is difficult to evaluate the efficacy of disinfectants due to the absence of a practicable cell culture system for these viruses. The purpose of this study was to screen sodium hypochlorite and ethanol for efficacy against Norwalk virus (NV) and expand the studies to evaluate the efficacy of antibacterial liquid soap and alcohol-based hand sanitizer for the inactivation of NV on human finger pads. Samples were tested by real-time reverse transcription-quantitative PCR (RT-qPCR) both with and without a prior RNase treatment. In suspension assay, sodium hypochlorite concentrations of ≥160 ppm effectively eliminated RT-qPCR detection signal, while ethanol, regardless of concentration, was relatively ineffective, giving at most a 0.5 log10 reduction in genomic copies of NV cDNA. Using the American Society for Testing and Materials (ASTM) standard finger pad method and a modification thereof (with rubbing), we observed the greatest reduction in genomic copies of NV cDNA with the antibacterial liquid soap treatment (0.67 to 1.20 log10 reduction) and water rinse only (0.58 to 1.58 log10 reduction). The alcohol-based hand sanitizer was relatively ineffective, reducing the genomic copies of NV cDNA by only 0.14 to 0.34 log10 compared to baseline. Although the concentrations of genomic copies of NV cDNA were consistently lower on finger pad eluates pretreated with RNase compared to those without prior RNase treatment, these differences were not statistically significant. Despite the promise of alcohol-based sanitizers for the control of pathogen transmission, they may be relatively ineffective against the HuNoV, reinforcing the need to develop and evaluate new products against this important group of viruses.

Corona Virus

Coronavirus adalah virus baru yang belum diidentifikasi pada manusia sebelumnya yang menyebabkan penyakit corona virus yang disebut COVID-19. Virus dapat dengan mudah menular dari orang ke orang yang membuatnya menyebar dengan cepat. Salah satu yang biasa gejala COVID-19 yang dapat dengan mudah diidentifikasi adalah demam. Seiring dengan semakin cepatnya perkembangan teknologi saat ini, teknologi memiliki peranan yang sangat penting dalam kemajuan kehidupan manusia. Teknologi juga dapat diterapkan di bidang kesehatan khususnya pendeteksi suhu tubuh pada manusia, agar pencegahan coronavirus dapat optimal maka suhu tubuh dan kebersihan dari tangan harus dijaga. Apabila suhu tubuh dan kebersihan tangan tidak terjaga sesuai peraturan normalnya orang sehat tidak menjadi ODP (Orang Dalam Pengawasan) jika suhu tubuh <38ºC dan apaliba suhu tubuh >38°C maka orang tersebut akan menjadi PDP (Pasien Dalam Pengawasan). Dari pemikiran tersebut maka penulis mengambil sebuah judul yaitu Perancangan Dan Implementasi Alat Otomatis Hand Sanitizer Dan Ukur Suhu Mandiri Menggunakan Microcontroller Arduino Berbasis Internet Of Things Pada PT.Mitra Kontruksi Untuk Mencegah COVID-19. Dalam penelitian ini komponen utama yang digunakan adalah mikrokontroler NodeMCU Esp8266 serta sensor suhu GY-906 dan sensor halangan inframerah. Alat ini nantinya dilengkapi servo motor serta alarm buzzer yang berfungsi memberi peringatan apabila suhu tubuh >38ºC, selain itu alat ini juga nantinya akan terkoneksi pada Smartphone melalui wi-fi yang akan menampilkan informasi mengenai suhu tubuh yang diukur.
