Abstract

In solving a complex problem is often less adequate sequential computing, especially in terms of execution time is very long, and thus become not fisibel. An interesting alternative to overcome the long computational time is the use of parallel computing. Kompuasi parallel performance can be measured by various metrics, one of them is isoefisiensi. With predictable isoefisiensi scalability of a parallel system. As a test program used in this study and the vector matrix multiplication, the matrix is partitioned following the chessboard pattern. Test program is executed on a computer with hypercube architecture. From the test results can be concluded that the parallel system is scalable because it requires a small increase in weight along with the increase in the number of processors.

Abstract

The purpose of identifying post-fire occupational safety is to ensure that a workplace or facility affected by a fire can resume operations safely and effectively. This includes measures to protect workers, prevent further damage, and minimize potential hazards that may arise after a fire. Primary data was obtained by conducting interviews and questionnaires were administered to select project personnel who held supervisory positions. Secondary data refers to information obtained by other individuals from various sources, such as the internet, literature, and previous research, Characteristics of Occupational Safety and Health (OHS) hazards that often arise in construction projects were obtained from literature research and observation, The HIRADC technique has demonstrated efficacy in identifying, evaluating, and categorizing hazards, in addition to ensuring appropriate mitigation strategies.
