Abstract

The purpose of this research is to analyze the value of erosion factors and the level of erosion hazard using the RUSLE method in the Lisun Sub Watershed, Nagari Silokek, Sijunjung Regency. This type of research is quantitative research. The results show that: 1) The erosion factor that most influences the low erosion that occurs in the Lisun Subwatershed is CP where the Lisun Subwatershed still has a very large forest area of 28,886.33 ha (70%) with high forest density so that the amount of erosion can still be controlled.2) The level of erosion hazard in Lisun Sub-watershed includes very light to heavy and consecutive land area in Lisun Sub-watershed from very light 0.247 tons/ha/year (30.65%), light 5.047 tons/ha/year (40.69%) medium 23.007 tons/ha/year (14.33%) and heavy 106.882 tons/ha/year (14.28%) with total erosion of 135.184 tons/ha/year.

Abstract

The research aims : 1) analysis hydraulic model in numeric modeling of flow Bayang watershed, 2) modeling spatial flood of Bayang watershed using HEC-RAS. Type thi research uses quantitative method with spatial approach. The data used for flood discharge is maximum rainfall in 2013-2022. Data were analysis using unsteady flow technique with software HEC-RAS and literature study. 1) The study produces 100 year periode discharge with a peak time of 1.27 hours which produces a period 2 year of 263.98 m3/sec, period 5 of 303.08 m3/sec, period 10 of 328.95 m3/sec, period 25 of 361.70 m3/sec, period 50 of 385.95 m3/sec and period 100 0f 410.07 m3/sec. 2) The model produce 1-D and 2-D models, the 1-D model produc a flood overflow depth of 3.03 to 1.71 meters while the 2-D model produce a flood overflow depth of 3 to 2 meters, villages of Sawah Laweh, Pasar Baru, Talaok, and Koto Barapak.

Abstract

The city of Padang Panjang, with its undulating topography, faces difficulties in utilizing land for settlement as population growth increases. This study aims to analyze the carrying capacity and accommodating capacity of residential land in the city. Descriptive quantitative research methods with data presented through tables and maps, calculations refer to the Ministry of Environment's 2014 carrying capacity guidelines and the Guidelines for Housing and Settlement Area Development and Development Plan (RP3KP). The results showed that in 2022, Padang Panjang City has a Settlement Carrying Capacity (DDPm) value of > 1. Kelurahan Ganting achieved the highest score of 14.4 and Kelurahan Pasar Baru had the lowest score of 1.8. The area of land suitable for settlement is around 672 hectares, can accommodate 264,309 people with a total of 66,077 housing units. Kelurahan Kampung Manggis stands out with a high capacity, able to accommodate around 34,864 people, while Pasar Baru has the lowest capacity, only 503 people.
