Abstract

Kebutuhan internet mempengaruhi pengunjung website semakin meningkat dan membuat beban traffic meningkat pada server, semakin banyak jumlah traffic ke server bisa menyebabkan web server menjadi down, jika digunakan dengan jumlah berlebih (overload). Server down karena tidak mampu dalam menjalankan request yang berlebihan, upaya untuk meningkatkan kinerja web server karena adanya akses request layanan yang sangat banyak, maka menggunakan sistem load balancing adalah solusi untuk mengatasi terjadinya server down. Server load balancing dapat bertugas untuk mendistribusikan beban kerja ke banyak server, dengan mempertimbangkan kapasitas dari setiap server yang ada. Pengujian ini dilakukan dengan 6 buah server. Yang masing masing mendapatkan 4000,8000, 12000, 16000 request, dengan pengujian menggunakan software apache benchmarking tool. Dengan Menerapkan load balancing Nginx mampu menstabilkan dan menjaga keseimbangan web server, dengan didukung 3 metode algoritma (Round Robin, Leas Connection, IP Hash) yang bisa digunakan dalam load balancing Nginx. Metode algoritma yang terbaik adalah Least Connection karena mempunyai stabilitas response time 116ms yang signifikan dan kecepatan response time nya lebih bagus dan mendapatkan 2300.96 req/s. DOI: https://doi.org/10.26905/jtmi.v6i1.3792

Abstract

Redistribusi protokol routing saat ini sering dijumpai dibanyak kasus seperti penggabungan dua perusahaan atau ketika jaringan internal didalam satu Autonomous System (AS) ingin terhubung dengan internet yang terdiri dari ribuan AS yang berbeda. Open Shortest Path First (OSPF) adalah salah satu protokol routing Interior Gateway Protocol (IGP) yang paling banyak digunakan, sementara Border Gateway Protokol (BGP) merupakan satu-satunya protokol routing yang digunakan di internet. Salah satu kekurangan BGP yaitu memiliki waktu konvergensi yang paling lambat dibanding yang lain [8]. Oleh sebab itu banyak penelitian dilakukan agar dapat mengurangi waktu konvergensi BGP diantaranya adalah dengan pengaturan keepalive dan hold time BGP. Pada penelitian ini dilakukan simulasi redsitribusi protokol routing OSPF dan BGP dengan mengatur nilai keepalive dan hold time BGP untuk menghasilkan waktu konvergensi yang cepat. Nilai optimal keepalive dan hold time pada penelitian ini adalah 30 detik untuk hold time dan 10 detik untuk keepalive yang menghasilkan rata-rata waktu konvergensi 28.86 detik yang lebih cepat dibanding penelitian sebelumnya [2].

Abstract

Rob is a flood disaster that is generally caused by the flow of strong water that rises to lower land. In other cases, the occurrence of tides is due to the meeting of tides with the flow of the river so that the overflow of water into the mainland. Therefore, to support the mitigation of tidal disasters, researchers took the initiative to design a water level monitoring tool to provide early warning information about tidal disasters in real-time. The design of the tool uses an ultrasonic sensor and a Wemos D1 R1 microcontroller as a prototype of seawater level detection devices, then sensor data will be sent to thingspeak to be monitored in real-time so as to produce output in the form of warning notifications via telegram on smartphones and social media information on Twitter and Facebook. The results of testing the system and tools are able to work as expected. When the sensor reads the water level between 26 <35cm it will be alerted to a telegram alert with a delivery time of 17 seconds, and the system will automatically post warning information via Facebook with a duration of 10 seconds and Twitter for 13 seconds. However, if the water level is <25cm, the hazard notification will appear continuously every 16 seconds by telegram. The results of testing the sensor data accuracy there is a difference of an average error value of 3.68cm with an error percentage of 7.7%.
