The review process in this journal employs a double-blind peer-review, which means that both the reviewer and author identities are concealed from the reviewers, and vice versa.</p> <p>The latest accreditation decree is No. <strong>10/C/C3/DT.05.00/2025, </strong><strong>dated 21 Maret 2025, valid until Vol. 10 No. 2 2028</strong></p> http://jurnal.polimdo.ac.id/index.php/jtst/article/view/1188 2025-09-02T14:58:39+00:00 Eunike Imania Kaligis eunimania0303@gmail.com Jeanely Rangkang jeanely.rangkang@sipil.polimdo.ac.id Beldie Aryona Tombeg eunimania0303@gmail.com

<p><em>Penjadwalan waktu pelaksanaan yang akurat merupakan aspek krusial dalam pengelolaan proyek konstruksi, terutama pada proyek gedung perkantoran berskala besar. Penelitian ini bertujuan untuk menganalisis estimasi waktu penyelesaian proyek menggunakan metode Program Evaluation and Review Technique (PERT), serta membandingkan dengan realisasi waktu proyek berdasarkan data Kurva S. Metode PERT digunakan untuk menghitung estimasi waktu rata-rata (te) dari setiap aktivitas proyek, dengan memperhitungkan waktu optimis, waktu kemungkinan besar, dan waktu pesimis. Hasil analisis menunjukkan bahwa pekerjaan struktur memiliki estimasi waktu penyelesaian sebesar 303 hari dengan probabilitas 96,56% (z = 1,824). Dibandingkan dengan realisasi di lapangan sebesar 321 hari, sehingga ditemukan keterlambatan sebesar 18 hari pada pekerjaan struktur. Keterlambatan ini disebabkan oleh beberapa faktor, seperti kompleksitas pekerjaan, durasi aktivitas yang panjang, serta ketergantungan antar disiplin kerja. Penelitian ini memberikan kontribusi dalam penerapan metode PERT untuk evaluasi kinerja waktu proyek konstruksi, serta sebagai acuan pengambilan keputusan dalam perencanaan waktu pada proyek serupa.</em></p>

<p><em>The distribution of clean water remains a challenge, especially in rural areas. To address this issue, the government has implemented the PAMSIMAS Program as an alternative solution for providing clean water. Howev er, due to the conventional distribution system being less than optimal, further analysis is conducted through numer ical simulations using the EPANET 2.2 software to identify problems and formulate improvement solutions. Existing condition data and technical specifications of the pipe network are used as input for the analysis, referring to the Minister of Public Works Regulation No. 18 of 2007 to evaluate pressure, velocity, and head loss at each node and pipe. Three simulations were conducted: the existing condition, system improvement simulation, and projection of clean water needs until 2040, using the geometric method to calculate population growth. In 2024, the water de mand for 224 residents was recorded at 0.257 liters/second, indicating that the flow velocity did not meet the re quired standard. As a result, improvements such as pump replacement and pipe diameter adjustments were neces sary. The 2040 projection estimates a population increase to 1,470 people with a constant service level of 18.93%, leading to a projected water demand of 0.319 liters/second. The simulation results indicate that replacing the 2 HP pump with a 3 HP unit, along with adjusting the pipe diameter from 40–50 mm to 20–40 mm.</em></p>

<p><em>Land use changes in the Melangit Sub-Watershed, Bangli Regency, have caused an increase in surface runoff, a decrease in infiltration capacity, and a risk of flooding in residential areas. This study aims to analyze hydrological characteristics and evaluate the capacity of the existing drainage system using a Geographic Information System (GIS) approach. The research methods included analysis of planned rainfall using the Gumbel distribution, calculation of planned discharge using the Rational method, and evaluation of channel capacity based on hydraulic parameters using the Manning equation. The results showed that the planned rainfall intensity for a 5-year return period was 177.5 mm/hour with a total runoff discharge of 40.89 m³/second. Residential areas produced the highest discharge of 11.39 m³/second, while industrial plantations produced the lowest discharge of 4.41 m³/second. Spatial analysis showed that the priority zone for drainage planning was in flat to sloping areas with high residential density. The research findings confirm that GIS-based drainage planning and conservation zoning are necessary to improve the effectiveness of runoff control and flood mitigation. In conclusion, the integration of hydrological analysis and GIS can be the basis for adaptive and sustainable drainage infrastructure planning.</em></p> <p><strong><em>Keywords:</em></strong><em> Hydrological analysis, Drainage, GIS, Surface runoff, Water management system</em></p>
