Abstract

Applying the Low-Impact Development (LID) approach in urban drainage systems can help control surface runoff, therefore mitigating the potential of flooding risk. However, its effectiveness varies widely, and various technical factors influence its performance. This study aims to determine the effectiveness and performance of LID units, namely bioretention and infiltration wells, in controlling surface runoff. The Center Park Housing area, covering an area of ​​11.53 hectares located in Palembang City, was chosen as the study area. The ability of the LID unit to reduce the volume and discharge of runoff, as well as the runoff coefficient, was simulated using the Storm Water Management Model (SWMM) program based on input from various design rainfall cases. There were four simulated design rainfalls, i.e. 108.76 mm (2-year return period), 133.20 mm (5-year), 149.38 mm (10-year), and 169.82 mm (25-year). The LID unit implementation scenarios were varied with the number of infiltration well units of 1 - 4 units per house plot. The number and area of ​​bioretention units were considered constant for all scenarios. The simulation results show that the LID implementation can reduce runoff volume and peak discharge and help decrease the runoff coefficient in the study area effectively, especially in the case of lower design rainfall (2-year). The performance of the infiltration wells unit in producing runoff losses is better than the bioretention unit because its construction structure has a larger storage capacity for a similar unit area. Although the LID method is quite effective in reducing runoff, its combination with conventional methods may produce better performance, so further research that discusses this needs to be addressed.

Abstract

Untuk menjaga keselamatan dan kesehaan kerja (K3) selama beraktivitas di dalam laboratorium penting untuk dilakukan K3 laboratorium yang jelas dan komprehensif. Tindakan keselamatan kerja ini harus disertai dengan cara kerja yang baik dan harus dipatuhi oleh seluruh teknisi laboratorium. Tahapan bekerja di laboratorium dimulai dengan memahami peraturan kesehatan dan keselamatan kerja, kepatuhan terhadap peraturan berpakaian, langkah-langkah penanganan bahan kimia dan peralatan laboratorium secara aman, dan pembuangan limbah yang tepat. Saat ini mayoritas laboratorium yang ada di Fakultas Teknik Universitas Sriwijaya belum sepenuhnya menerapkan K3. Hal ini terbukti masih kurangnya fasilitas, peralatan dan rambu-rambu K3 yang ada di lingkungan sekitar. Terlebih lagi tenaga laboran yang meliputi kepala laboratorium, asisten lab serta teknisi laboratorium belum pernah mendapatkan pelatihan terkait K3 maupun sertifikasi K3. Oleh karena itu dipandang perlu untuk melakukan pendampingan dan bimbingan teknis terkait penerapan K3 di laboratorium dan lingkungan Fakultas Teknik Unsri.
