Abstract

Abstrak— Analisa dinamik pada struktur merupakan tahapan lanjutan bagi profesional konstruksidalam memahami bagaimana suatu struktur akan berperilaku. Jurnal ini meneliti konvergensiperhitungan numerik tiga metode yang sering digunakan, yaitu Newmark, Chung-Hulbert dan CentralDifference. Rangka beton 2 lantai akan menjadi acuan untuk melihat keandalan ketiga metodenumerik tersebut, ekstraksi matriks K dan matriks M akan diambil dari program bantu SAP2000 daniterasi numerik akan memakai python sebagai solver nya. Kecepatan konvergensi untuk kondisi tanpabeban luar dicapai lebih cepat 1.5% dengan eksplisit central difference, sedangkan Newmark danChung-Hulbert tetap mencapai konvergen meskipun dnegan pengaruh beban luar.Abstract - Dynamic analysis of structures is an advanced stage for construction professionals inunderstanding how a structure will behave. This journal examines the convergence of numericalcalculations of three frequently used methods, namely Newmark, Chung-Hulbert and CentralDifference. The 2-storey concrete frame will be a reference to see the reliability of the three numericalmethods, the extraction of matrix K and matrix M will be taken from the SAP2000 output andnumerical iteration will use python solver. The convergence rate for conditions without external loadwas achieved 1.5% faster with explicit central difference, while Newmark and Chung-Hulbert stillachieved convergence despite the influence of external loads.

Abstract

The Sidoarjo District Manpower Office has the task of assisting the Sidoarjo Regent in carrying out government affairs which fall under regional authority in the field of employment. The Sidoarjo District Manpower Office manages employment data which includes data on job seekers, companies, job vacancies and job training. This still needs special attention because current employment management is not well managed, job seekers in Sidoarjo Regency still have difficulty in choosing job vacancy information. In addition, the Sidoarjo Regency Manpower Office has difficulty in preparing training programs that are in accordance with the needs of the labor market because data processing is not yet online and integrated. This research was conducted with the aim of building an Employment Management Information System application at the Sidoarjo Regency Manpower Office. It is expected that the application built by the author is able to facilitate the Sidoarjo Regency Manpower Office in managing employment data and providing the best service to residents in Sidoarjo Regency. Keywords: Website, Information System, Sidoarjo Regency, Manpower Office.
