Abstract

The increasing use of electrical energy in society in 2020 is closely related to the pandemic problem that is occurring. Increased household activity causes a surge in energy in the household sector. This increase in energy consumption needs to be balanced by providing exposure to the utilization of existing electrical equipment in households. The lighting system give an important role in energy consumption in the household sector. The dedication carried out is by providing knowledge on the use of the lighting system, the rules in PUIL 2000 and the calculation of the Basic Electricity Tariff (TDL) in 2020. Submission of this will certainly increase public understanding of energy savings so that it can contribute to overcoming the problem of electricity devisit occur.

Abstract

Banyak pedagang kecil di Kota Medan didirikan degan konsep usaha rumahan karena menurunnya keadaan ekonomi. Mitra, Usaha Kakak Adik Minuman Serbuk Jahe Segar Mawar, merupakan usaha rumah tangga dengan modal dasar 10 juta. Disamping memiliki keterbatasan modal, usaha tersebut belum melakukan penjualan menggunakan media online. Penerapan teknologi sistem pengaduk otomatis dijadikan solusi untuk memudahkan proses dan meningkatkan produksi. Penerapan sistem pengaduk otomatis pada saat memasak juga dapat meningkatkan kualitas produk yang akan dipasarkan. Begitu juga, pembuatan situs penjualan online dengan menampilkan foto bahan serbuk jahe akan meningkatkan penjualan pada saat ini. Disamping peningkatan proses penjualan dan pemanfaatan media penjualan online. tim pengabdian juga melakukan edukasi sistem manajemen serta penerapan teknologi yang sesuai untuk mencapai peningkatan penjualan. Hasil yang diperoleh dari pengabdian ini adalay diterapkan teknologi sistem pengadukan serta penignkatan penjualan menggunakan media online

Abstract

System of Linear Equation  where  is a non-singular and square matrix .  Method for solving System of Linear Equation consist of direct method and indirect method. Further indirect methods were divided into two, that is stationary and non-stationary. This research will conduct a comparative study of several indirect methods and direct methods in solving several cases of Linear equation systems. Some methods that will be compared in this research are jacobi, gauss-seidel, SOR, conjugate and biconjugate gradient. Testing several methods for some kind of matrix is useful to understand the characteristics of each method in solving different types of matrices. The result show that non-stationary such as conjugate and biconjugate has a less computation and faster to convergence compared to stationary method for several symmetric and non-symmetric matrices
