Abstract

Organizational leadership is the ability to influence a group towards the achievement of a goal, so that the creation of good leadership and low work stress in the organization can improve employee performance to achieve a goal. This study aims to determine the effect of leadership and work stress on the performance of lecturers and education staff at the Medan Senior High School of Health in 2021. This research is a quantitative study using a survey method, in which basic data from a sample of a population is collected using a questionnaire instrument in field. The data used in this study is primary data. Primary data is obtained directly from the original source through the distribution of questionnaires to respondents. The research population was all lecturers and education staff at the Medan Senior High School of Health as many as 50 people with the number of samples used as total sampling. Data collection techniques were carried out by interviewing and distributing questionnaires to respondents. Classical assumption test is done by normality test, multicollinearity test, heteroscedasticity test. The data analysis technique used the T-test and F-test. The results showed that the t-count value > t-table, namely the leadership t-count value 2,978 > 1.677 and the t-count compensation value 2,040 > 1,677, this indicates that there is a positive and significant influence between leadership and work stress. on the performance of lecturers and education staff. Meanwhile, it simultaneously shows that the calculated F value > F table (4,641 > 3,20).

Abstract

Penelitian ini mengkaji pengaruh arang kayu sebagai agregat kasar terhadap karakteristik campuran beton. Tujuannya adalah untuk mengetahui pengaruh arang kayu sebagai agregat kasar terhadap karakteristik campuran beton dan untuk mengetahui perubahan sifat campuran beton akibat penambahan arang kayu sebagai agregat kasar. Variasi proporsi arang kayu yang digunakan adalah 20 % dan 25 %. Pengujian meliputi uji kuat tekan. Hasil penelitian menunjukkan bahwa penggunaan arang kayu pada proporsi 20 % dan 25 % masih memenuhi standar kekuatan structural dengan penurunan kekuatan tekan yang menunjukkan bahwa proporsi tinggi arang kayu dapat mengurangi performa structural beton. Ketahanan terhadap serapan air meningkat seiring dengan penambahan proporsi arang kayu, karena sifat pororitas arang kayu yang cenderung meyerap lebih banyak air dibandingkan agregat kasar konvensional. Kesimpulannya, arang kayu dapat digunakan sebagai agregat kasar alternatif dalam campuran beton dengan proporsi optimal dibawah 20 %, sehingga memanfaatkan limbah arang kayu (biomassa) dan meningkatkan keberlanjutan dalam industri kontruksi.
