Pengaruh Komunikasi Horizontal Terhadap Kinerja Pegawai pada Dinas Perhubungan Kabupaten Jember

Abstract

In the era of digitalization and globalization, government organizations are required to have an effective work system to improve apparatus performance. Horizontal communication, defined as the exchange of information between colleagues with equivalent authority under the same leadership, is a crucial mechanism for achieving organizational goals. This study aims to determine the effect of horizontal communication on employee performance at the Department of Transportation (Dinas Perhubungan) of Jember Regency. This research employed a quantitative associative approach to analyze causal relationships between variables. Data were collected from 59 respondents through a questionnaire measuring horizontal communication indicators (task coordination, problem-solving, information sharing, and conflict resolution) and performance indicators (quality, quantity, reliability, and work attitude). Data analysis was performed using SPSS version 25, including Rank Spearman Correlation and partial t-tests. The results of the Rank Spearman test showed a strong positive correlation (0.779) between horizontal communication and employee performance. Furthermore, the t-test yielded a t-count (8.881) greater than the t-table (2.002) with a significance level of 0.000, leading to the rejection of the null hypothesis (Ho). The study concludes that horizontal communication has a significant positive effect on employee performance. Effective interaction between peers facilitates faster problem-solving and accurate technical information exchange, which directly contributes to higher quality output and work efficiency. Therefore, maintaining cooperative work relationships and improving information transparency are recommended to sustain organizational performance.
