Motor listrik merupakan mesin listrik yang merubah energi listrik menjadi energi gerak. Pemanfaatan energi gerak ini yang kemudian banyak digunakan oleh beberapa gedung bertingkat untuk mempermudah proses pendistribusian air. Kantor Walikota Pekanbaru memiliki motor listrik untuk pendistribusian air yang memiliki kapasitas daya 7,5 kW sebagai mesin penggerak pompa. Penelitian ini dilakukan pada motor induksi tiga phasa di kantor Walikota Pekanbaru untuk mengetahui kinerja motor terhadap perubahan bukaan valve. Saat bukaan valve minimal diperoleh arus stator 6,215 Amper, arus rotor 4,180 Amper, putaran rotor 2979 rpm, torka induksi 8,044 N.m dan torka beban 7,987 N.m. Saat bukaan valve medium diperoleh arus stator 8,389 Amper, arus rotor 7,236 Amper, putaran rotor 2963 rpm, torka induksi 14,257 N.m dan torka beban 14,080 N.m. Saat bukaan valve maksimal diperoleh arus stator 10,006 Amper, arus rotor 9,319 Amper, putaran rotor 2950 rpm, torka induksi 18,080 N.m dan torka beban 17,798 N.m.
Data storage media, or what is often referred to as a database is something that is quite vital for technological developments. As the amount of data increases, it allows database services to experience downtime. For this reason, it is necessary to build an infrastructure that can replicate itself, so that it will avoid downtime. This infrastructure can be built using a container orchestration tool called Kubernetes which has high availability and autoscaler features, so it can replicate and guarantee service availability, to avoid downtime. This research builds a MongoDB NoSQL database service. This service is built using micro Kubernetes clusters from several different data centers. This service also implements a horizontal pod autoscaler feature that is capable of replicating pods, to increase high availability and avoid downtime. The autoscaling process will be tested by providing a load request for the service. Testing is done several times on each server. This study will compare the MongoDB service that was built monolithically with a micro Kubernetes cluster, and with HPA features and without HPA features by paying attention to several things. Based on Response Time, Response Code per Seconds, and CPU Usage, the results obtained are that the service built on a micro Kubernetes cluster with HPA features is the best, with a constant response time value below 100 ms, Response Code per Seconds reaches 500 threads per second. seconds, and CPU Usage in the range of 30 – 55%.
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.
