Abstract

Downtime pada cloud computing seringkali memiliki dampak langsung penggunanya. Situs besar dapat kehilangan jutaan dana atau lebih dalam pendapatan setiap menit situs mereka tidak tersedia. Dengan menggunakan server load untuk balancing yang dimungkinkan untuk memberikan keandalan yang lebih baik karena algoritma load pada balancing digunakan untuk meminimkan kesalahan serta memungkinkan kemungkinan pada peningkatan dan pemeliharaan server tanpa mengganggu layanan yang ditawarkan. Jika server macet dan perlu dimatikan karena pemeliharaan, itu hanya akan menyebabkan penurunan kinerja, sementara layanan masih tersedia di server yang masih aktif. Penyedia layanan perlu menyesuaikan dengan perjanjian tingkat pada sebuah layanan yang menggambarkan batasan untuk layanan yang diberikan, seperti waktu respons, waktu aktif, bandwidth, dll. Karena padatnya komunikasi lintas jaringan dapat berubah dengan cepat sehingga sangat penting bagi penyedia layanan untuk dapat beradaptasi dengan perubahan yang mungkin terjadi karena untuk meningkatkan lalu lintas terhadap server. Load balancing menyediakan kemungkinan untuk menyesuaikan jaringan dengan permintaan yang banyak dan meningkat pada lalu lintas berdasarkan dinamika cloud computing.

Abstract

Fossil fuel reserves are limited while the growing demand for energy utilization. It leads to an acceleration of renewable energy use. One of the renewable energy resources is solar energy, called the photovoltaic system. This paper uses a photovoltaic solar system consisting of a solar panel module, DC-DC boost converter, voltage divider, ACS712 as a current sensor, Arduino Uno, and load resistor. Maximum Power Point Tracking (MPPT) controller is implemented to track the maximum power point of the solar panel system using a boost converter based on the Incremental Conductance algorithm embedded in Arduino UNO. The PV system with MPPT controller is designed with PV 20 W. The testing of the ACS712 current sensor and voltage sensor show error values of about 1.82% and 0.83%, respectively, which are acceptable limits. Besides, the DC-DC boost converter is also tested, and its performance shows an increase in the output voltage. The test result of the PV system with MPPT control based on the Incremental Conductance algorithm shows the average value of the PV power output with resistive load at 36 Ω is about 7.34 W, while the PV system without MPPT is about 6.07 W. Thus, the Photovoltaic system using MPPT controller based on the incremental conductance algorithm can control PV power output at the maximum power point.

Abstract

During the pandemic, many events are held online. conference registration (webinars, seminars, workshops) which basically will cause its complexity for admins if there are excess registrants or over participants from achieving the registration quota target. In addition, the admin must monitor regularly to ensure that there are no excess registrants that result in inefficient. The method used in the development of this application is the waterfall method. The purpose of this research is to build a web-based conference registration system that can make it easier for admins/organizers to manage the registration process. The results of this study the system can display the results of the recap from the admin so that the user can see the quota from the conference registration organized by the committee as well as testing of users from several tests to produce an application system that runs well.
