Abstract

This study evaluates the hydraulic performance of Palembang"™s drainage system under passive and pump-assisted conditions using EPA SWMM 5.1 modeling. The passive scenario (pump inactive) revealed critical vulnerabilities, particularly at Junction 19, where water levels rose 1.8 meters, causing overtopping and backwater effects extending 285 meters upstream. This confirms the system"™s inability to handle extreme rainfall (>50 mm/hr) without mechanical intervention. In contrast, activating the 650 LPS pump system reduced flood volumes by 89% and maintained water levels 0.6 meters below channel banks, eliminating overflows. The simulations demonstrate that Palembang"™s flat topography (0.2% slope) necessitates hybrid drainage solutions combining gravity flow and targeted pumping. Key findings include: (1) Junction 19 requires prioritized upgrades due to persistent bottlenecks, (2) pump activation thresholds must be optimized to 0.85-meter water levels for timely response, and (3) system-wide flood duration can be reduced by 78% with mechanical assistance. These results provide a blueprint for climate-resilient urban drainage in low-gradient delta cities, though long-term success depends on regular maintenance, sediment control, and adaptive pump operations tied to real-time weather forecasts.

Abstract

Penelitian ini bertujuan untuk menganalisis penerapan manajemen waktu pada proyek pembangunan Jalan Lingkar KM. 10 menuju TPA Simpang Bandara dan Sungai Limpah oleh CV. Dua Pandawa Sakti. Metode yang digunakan adalah mix method dengan data yang diperoleh melalui dokumen proyek, observasi lapangan, dan wawancara. Hasil analisis menunjukkan bahwa manajemen waktu diterapkan secara efektif melalui penyusunan jadwal kerja, monitoring progres, analisis deviasi, dan tindakan korektif. Kurva-S menunjukkan bahwa progres fisik proyek lebih cepat dari rencana. Keberhasilan ini dipengaruhi oleh koordinasi dan penerapan sistem manajemen waktu yang baik. Kata kunci : Manajemen Waktu, Pembangunan Jalan, Proyek Konstruksi
