Abstract

Penelitian ini adalah untuk menghitung besar arus gangguan hubung singkat pada Saluran Kabel Bawah Tanah (SKTM) 20 kV di Kota Pontianak. Gangguan hubung singkat yang mungkin terjadi di dalam jaringan distribusi ada 3 (tiga), yaitu: gangguan hubung singkat 3 fasa, gangguan hubung singkat fasa ke fasa dan gangguan hubung singkat 1 fasa ke tanah. Dengan menulis penelitian ini dapat mengetahui besar arus hubung singkat dan acuan dalam penyetingan peralatan proteksi saluran kabel bawah tanah 20 kV di Kota Pontianak. Perhitungan ini dilakukan pada penyulang Mawar 1, Dahlia, Megamall, Krisan 1, Kenanga 1, Teratai 1, dan Sakura dengan asusmsi titik gangguan hubung singkat pada 25%, 50%, 75%, dan 100% dari panjang penyulang. Didapat hasil perhitungan gangguan arus hubung singkat SKTM di Kota Pontianak dengan bentuk kurva linier. Dapat disimpulkan bahwa arus hubung singkat tiga fasa lebih besar dari fasa-fasa maupun fasa-tanah. Semakin dekat titik gangguan dengan sumber, maka semakin besar arus gangguan yang dapat terjadi. Dan semakin kecil kapasitas trafo, maka arus gangguan hubung singkat juga akan semakin kecil.

Abstract

Construction is one of the sectors that the government relies on to contribute to national growth; the impact of this policy is that the number on the projects is not balanced with construction experts, thereby increasing the workload of construction employees, coupled with the pandemic, limiting construction project activities which are labour-intensive activities that require a lot of interaction and physical activity in the field. This study aims to determine the impact of a workload and responsibility load on work stress and job performance in construction projects during the pandemic. This research uses a correlational descriptive quantitative approach: the population in this study is 100 construction employees in Indonesia. The sampling technique is total sampling with multiple linear regression. The result showed that workload significantly affects the responsibility load on construction project workers in Indonesia. The workload has a positive and significant impact on Indonesian construction project workers. Responsibility load has a positive and significant effect on Workstress on Project Construction workers in Indonesia. The influence of responsibility load on work stress is negative and significant. Work stress on employees does not affect job performance on employees. Namely, there is no effect if construction employees have high work stress on their work. It does not affect job performance. The work stress variable has no positive or significant effect on job performance. Further research can incorporate variables that influence job performance, such as workload, responsibility load, work stress, and others, to improve job performance at construction.
