Abstract

Along with technological developments in the field of civil engineering, various systems are used to reduce the impact of earthquakes on the structure. One system that has long been developed is a passive prevention system consisting of seismic isolation. Buildings that use seismic dumper are expected to fail structure when an earthquake occurs. This study discusses the comparison of internal forces in buildings using base isolation and without base isolation. The building which is the case study is the Indonesian Heritage Foundation school building in Cimanggis. The analysis uses the 2016 ETABS program. Earthquake analysis uses the Spectrum Response method. From the research results, it is known that the building which was installed with an insulator shakes the structure to 1,344 seconds. The vibration period of the structure increased 41% from the vibration period of the structure which still used a fixed base of 0.796 seconds. Seen from the intersection between floors the maximum direction of X can be reduced by 15.4% by installing an insulator. The same thing happened to the maximum inter-floor deviation for the Y direction deviation is muted by 27.75%. Base isolation installation reduces the moment in a column by 36% in the earthquake X direction and 61% in the earthquake Y direction. For column shear force is reduced by 58% in the earthquake X direction and 75% in the earthquake Y direction. Base isolation can reduce basic shear force in buildings by 24.49% in the X direction of the building and 22.24% in the Y direction.

Abstract

The aim of this research is to find out how the residents of Rijang Pitu sub-district, Maritengngae District, and Sidenreng Rappang Regency perceive the existence of broiler chickens. The research was conducted from July 29 to September 29 2023 at Rijang Pitu Village, Maritengngae District, Sidenreng Rappang Regency. sample used in this research were people who lived close to broiler chicken breeders with a total of 38 respondents. Samples were taken using purposive sampling. The type of study carried out in this research is descriptive and quantitative with a Likert scale. To measure the subvariables odor, fly population, and livestock waste, the measurement scale is very disturbed, disturbed, quite disturbed, not disturbed, and very not disturbed. The results of the research show that the odor generated from livestock is in the moderately disturbed category with a weight value of 374, the fly population generated from livestock is in the disturbed category with a weight value of 392, and the waste generated from livestock is in the moderately disturbed category with a weight value of 366. It can be concluded that the perception of society as a whole is in the moderately disturbed category with an overall weight of 1.132.
