50 Kota Regency has quite a lot of potential water sources. One of them is the Kamuyang River spring. This spring has been utilized by the surrounding community to meet their daily water needs. The abundant water discharge in the rainy season allows the utilization of this water to sometimes exceed the capacity that can be utilized by residents. However, it is possible that the discharge will decrease significantly in the dry season. This study examined how much potential the Kamuyang River spring can be utilized. The purpose of the study was to determine the amount of the mainstay discharge from the Kamuyang River spring using the NRECA method. The mainstay discharge taken was 80% reliability and 90% reliability of the discharge produced by the spring. From the calculation results, the mainstay discharge of 80% Q80 was obtained as 0.000424 m3/sec or equivalent to 36.599 m3/day, and the mainstay discharge of 90% Q90 was 0.000184 m3/sec or equivalent to 15.883 m3/day. By knowing the mainstay discharge from this water source, it is hoped that the utilization and exploitation of water at this location will not exceed the existing capacity so as not to damage the groundwater cycle in the Kamuyang River area and its surroundings.

Soil density is closely related to determining the design CBR on road pavements. In this study, soil density testing used standard proctor test methods (ASTM D-698) to obtain the optimum water content (w) and maximum dry weight (γ_d). This study obtained an optimum water content of 24.72% and a maximum dry weight of 1.61 gr/cmᶟ. Meanwhile, for the CBR labor test, the water content obtained from the results of the previous soil density test was used, while for the CBR labor test based on the ASTM D-1883 standard with 3 test samples, namely 10 impacts, 25 impacts and 56 impacts. From the results of the CBR labor obtained at a decrease of 0.1 inches with 10 impacts was 7, for 25 impacts it was 8.74 and 56 impacts it was 9.81. This value is used to determine the design CBR value which is associated with 95% maximum dry weight on soil compaction, the value is 9.6%. This value, if adjusted according to pavement standards, is included in the fairly good category of soil and can be used for sub-base on the pavement of the Eka Jaya Permata II housing complex in Payakumbuh City.

Gunung Malintang Sub-district is the largest Sub-district in Pangkalan Koto Baru District, Lima Puluh Kota Regency, West Sumatera Province. With an area of 249.43 km2, Kenagarian Gunung Malintang occupied 35.03 % of Pangkalan Koto Baru District’s total area. Crossing by a major river, Batang Mahat river, made this area hit by floods frequently which brings loss to the local community. Building dams is one of the solution for controlling the flood problems. As we know, dams could be a storage for the excessive water during floods, and it could also be a water resource during the dry season. For the reasons mentioned above, it is necessary to analyze the flood area on the location where the dams would build. The aim of this research is to calculate the discharge of probable flood (flood routing) using Muskingum method,and to estimate the storage capacity of the basin on the proposed construction site using relationship curve between elevations – storage area – storage volume. From the flood routing calculation of the probable flood for 100 year of return period, the inflow discharge 325,0911 m3/s and the outflow discharge is 165,6724 m3/s. The peak flood discharge occured at 3 rd hour. So the probable storage balance based on inflow – outflow discharge is 13,773,771.82 m3 in volume. From the storage capacity determination, using topographic analysis obtained 4.467.693,43 m2 in storage area and 30.213.084,779 m3 for storage volume. The dead storage capacity placed on the elevation +156 m above msl. The conclusions of the study indicates that the dead storage capacity meets the probable storage balance from flood routing. Which means that the design dam could be constructed at the elevation +156 m.

Every housing complex must have adequate road access because roads are a means of public transportation used by the community to support daily activities. Road infrastructure makes transportation easier and allows people to carry out activities. The road foundation layer will experience a decrease in the soil's bearing capacity as traffic flow increases, because the road structure distributes the load to all layers beneath it and supports the weight of vehicles passing on it. In circumstances like this, road construction must be of the utmost importance, and data about the existing soil on the site must be tested first. In this research, the author took a residential road that had just been built and still had a layer of compacted pavement. By making this road, people can more easily access transportation and feel comfortable when using it. Field density analysis was carried out on Jalan Perumahan Ekajaya Permata 1 Sicincin, Payakumbuh City. The sand cone method or sand cone test is used to calculate the degree of soil density. Various measurements are calculated, including sand bulk density, soil bulk density, water content, dry soil bulk density, and degree of field density. Tests were carried out at ten points at a distance of 25 meters each. The average soil water content is 7.73%. According to SNI 03-2008-1992, the recommended value of soil density is 95%. The test results show that the average degree of density in the field is 72.51%. Because the soil density in the field does not yet meet the soil density requirements of 95%, it is necessary to increase the compaction further until it meets the specified density requirements.
