Abstract

The building performance is an innovative approach that discusses planning, design, construction methods, and the users of the building. To ensure the building functions as intended, maintenance and care are essential. An analysis of user satisfaction regarding building performance reflects users' needs and expectations. Politeknik Negeri Padang, a vocational higher education institution established for 37 years, warrants a user satisfaction analysis of its facilities to maintain comfort in its activities. This research was conducted through a questionnaire survey with 700 respondents, including staff, educators, and students. The analysis using the Suitability Level approach identified three priority indicators for improving building performance: information technology facilities, the condition of public facilities like restrooms, parking, and pantries, and the cleanliness of public toilets. Meanwhile, the Importance and Performance Analysis (IPA) highlighted four key areas for performance enhancement: availability of trash bins and cleanliness of the environment, public facilities such as pantries, toilets, and parking areas, room temperature issues, and information technology facilities like internet connectivity.

Abstract

Sedimentation is one of the problems that often occurs in rivers. Sedimentation that occurs continuously will cause siltation of the riverbed so that it can cause flooding due to reduced cross-sectional capacity of the river. Understanding these conditions, this study was conducted to examine the distribution of sediment transport that occurs in rivers. The river that is the location of the study is Batang Kuranji River which is located in the city of Padang, West Sumatra. HEC-RAS version 6.1 was used to model and simulate the sediment transport process. Simulations were carried out with a duration of 100 days and three flow conditions, flood discharge at return times of 2, 5 and 10 years. The sediment transport function used is the Meyer Peter-Muller equation. The results indicate the occurrence of sedimentary material deposits scattered throughout the study location. The total volume of sediment deposit in flood discharge conditions for 2, 5 and 10 years, respectively, is 6,978 m3; 2,989 m3 and 132 m3. The highest sediment deposit occurred in the simulation with a 10-year return period discharge at RS 14 (STA 1+350) which was 5,141,533 m3. After analysis, the high sediment deposition in the Batang Kuranji river section is caused by a decrease in flow velocity due to the influence of tides at the river estuary.

Abstract

Ladang Laweh Irrigation District Dam is located in Sicincin nagari, Padang Pariaman Regency with an irrigation service area of 1,140 Ha. The Ladang Laweh Irrigation Area weir receives flow from the Batang Mangor river which is included in the Batang Mangor watershed. On September 22, 2021 a flood occurred on September 22, 2021 resulting in an overflow with a height of 2.5 m above the lighthouse with an estimated discharge of 141.946 m3 /dt resulting in runoff flow in the area upstream of the bending. Analysis of the capacity of the existing river upstream of the weir was carried out with a 25-year plan flood discharge. Modeling is done by analyzing 15 years of rain data and catchment area starting from the location point of the weir upstream. The validation results under full bank capacity conditions obtained the closest match to the theoretical flood discharge value of the Nakayasu method. The simulation results show that the existing cross section of segments P1 to P19 at the Korong Gadang location is inundated during flood events with river capacity in several locations exceeding the maximum capacity. The results also provide recommendations for flood management by suggesting the addition of river embankments at locations that experience inundation.
