Abstract

Procedures for planning earthquake resistance for building and non-building structures, SNI 1726:2019 have been approved as a revision of procedures for planning earthquake resistance for building and non-building structures, SNI 1726:2012. With the implementation of SNI 1726:2019, existing buildings should be re-evaluated for their safety against this new regulation. This research examines changes in the performance of shophouse structures in the cities of Sidikalang, Tarutung, Padangsidimpuan, Sei Rampah, Tebing Tinggi, Limapuluh, and Lubuk Pakam. The results show that as a result of the change from SNI 1726:2012 to SNI 1726:2019 there was an increase in the value of the base shear force in the cities of Sidikalang, Sei Rampah, Tebing Tinggi, Limapuluh, and Lubuk Pakam with values respectively 32%, 8%, 11%, 7 %, and 10%. However, in the cities of Tarutung and Padangsidimpuan there was a decrease in the basic shear force value of 3% and 30%. The increase in base shear force is directly proportional to the increase in drift and interstory drift. The interstory drift that occurs is still below the permitted interstory drift.

Abstract

The title of this research was The Influence of Communication Strategy and Prime Service on Library Members’ Satisfaction at the Library of Politeknik Negeri Medan. The research used the theory of satisfaction. Kotler (2014) points out that there are two theories of satisfaction: theory of performance expectation and theory of cognitive inappropriateness. Theory of performance expectation states that consumer satisfaction is the function of consumers’ expectation of the result. If the result is in accordance with what has been expected, consumers will be satisfied, if it exceeds what has been expected, they will be more satisfied, but if it is not in accordance with what has been expected, they will be dissatisfied. The population was 5,994 members of the library, and 98 of them were used as the samples, taken by using Slovin formula. The data were gathered by using questionnaires and conducting documentation and observation. The result of the research showed that the factors of communication strategy and prime service had positive and significant influence on library members’ satisfaction which indicated that the better the communication strategy and the prime service, the higher the library members’ level of satisfaction.
