Abstract

Matlab software was applied in solving physics cases in electronics using value calculation programs and Eigenvectors. The physics case solved is an moving oscillator circuit consisting of five capacitors and four inductors. The purpose of this program is to determine the value and the Eigenvectors that can be obtained. The method used is to utilize the problem of values and Eigenvectors in the Matlab program. In the case of oscillator motion, each capacitor's size and inductor system have been determined according to the system.. The equation of motion for the capacitor and inductor system is reviewed at each point of the inductor and the function used is  called the ansatz function, then differentiated twice concerning time. By using the Matlab program application, the results obtained show that by using eig (Eigen) command the Matlab program can accurately show the results of running (execution) values and Eigenvector.

Abstract

The dissemination activity of exploring damen (rice straw) waste as liquid organic fertilizer is a form of Tridharma of higher education for community service practiced by four lecturers. This activity has several main goals: increasing public awareness, particularly among residents of RT 20 Sadar Sriwijaya Village, Bandar Sribhawono District, about the importance of utilizing damen waste to be used as liquid organic fertilizer, rather than being thrown away or simply burned after the harvesting process is complete. Socialization activities are carried out in two ways: material delivery and practice daily. Based on the socialization, it was discovered that the participants achieved the socialization's objectives with good criteria in general. As a result, the public knowledge, particularly among residents of RT 20 Sadar Sriwijaya Village, Bandar Sribhawono District, East Lampung Regency, on the use of damen waste and chicken eggshell waste is still low, so socialization is required to raise awareness of the use of agricultural waste as fertilizer

Abstract

The need for telecommunications access continues to increase. This is accompanied by the need for access to internet services. Within the increasing number of service users every time the improvement of quality of service is needed. jz power control method on the interference, used two schemes of power control method that is fixed power control, and adaptive power control. The result of simulation obtained by CDF analyisis scheme of fixed power control able to improve SINR equal to 11,45% and adaptive power control have value of improvement 8,65% in downlink period. And in uplink period increase of SINR equal to 3,29% with fixed power control and 2,24% with adaptive power control.
