Abstract

The planning of the Altertantif Road Development Project in Kuta District, Badung Regency, Bali Province was carried out to facilitate access to transportation in the area and to overcome traffic congestion at the Jalan Raya Kuta - Jalan Blambangan intersection. The implementation plan of the Road Construction Project over the Mati River, Kuta District, Badung Regency, Bali Province has various risks that may occur. Risk management is needed to minimize the impact and possibility of risks that will occur in the Road Construction project over the Dead River, Kuta District, Badung Regency, Bali Province. The method used in this research is descriptive qualitative method, namely interviews and brainstorming with competent parties and parties involved in the Road Construction Project over the Dead River, Kuta District, Badung Regency, Bali Province with a total of 25 respondents. Each respondent responds to the likelihood of a risk occurring (likelihood) and responds to the impact/influence that occurs due to the risk (consequences), then will get a risk assessment by multiplying the mode value of the frequency/probability of risk occurrence (likelihood) with the mode value of the influence/impact of risk (consequences). In this study, 34 risk identifications were obtained. These risks include 6 (17.65%) unacceptable risks, 21 (61.76%) undesirable risks, 7 (20.59%) acceptable risks, and 0% or no risks classified as negligible

Abstract

Sawangan Beach is located directly facing the Indian Ocean, the high waves and the generation by the wind which produce great energy that hits Sawangan Beach. The coastline was a setback when, around 2010, the access from Sawangan Beach to Pura Geger had turned into rock because the sand on the beach was increasingly eroding. The increasingly steep coastal contours can interfere with fishing activities and the existence of existing groin buildings that are hit by high waves causes the position of the protective stones to not function properly. Therefore it is considered necessary to know the wave height and period at Sawangan Beach. This wave height calculation can later be used in planning appropriate coastal protection structures on the beach. Calculation of wave height in this study focuses on wave generation due to wind, which is called a wind setup using the hindcasting method. Data In determining wave height, wind data is needed. Monthly maximum average wind data from BMKG sources includes 8 directions and wind speeds. The dominant wind is cdaric eastward c, namely c40.83%. Forecasting wave height (hindcasting) from the calculation of the wind stress factor and effective fetch, the value of the wave height (H) is 2.75 meters with a wave period (T) of 10 seconds

Abstract

The Oongan Irrigation Area, which is located in East Denpasar as part of the Tukad Ayung River Basin, has a potential land area of 1781 Ha, but only 617 Ha has been utilized. In March 2019, the average discharge reached 680 l/second, while the Oongan intake gate required a discharge of 880.7 l/s for the rice growing period. Based on these data, there is a need for in-depth research in the Oongan Irrigation Area regarding the efficiency and effectiveness of irrigation canals.. The research method used is the survey method. Based on the results of the analysis of the efficiency of the primary and secondary canals and the effectiveness of the Oongan Irrigation Area, the percentage results were 80.47%, 94.1% and 35% which showed that the primary canal was not efficient and irrigation that was not effective was below the standard value, namely 90% and 55%. There needs to be an improvement both in the water management system and the physical improvement of irrigation infrastructure. Meanwhile, secondary canals get an average yield with a percentage of 94.1% which is included in the efficient category so that it needs to be maintained and carried out maintenance through operational and maintenance activities on irrigation canals.

Abstract

Soil investigations in the form of hand boring, SPT tests, and laboratories were carried out on Jalan Pura Demak Denpasar City. The purpose of this study is to determine the characteristics of the soil in the area. Handboring results showed 0 to 2.5 m of clay soil, depth of 2.5 to 3.5 m of sandy silt rock tuff, depth of 3.5 to 4 m sandy clay, depth of 4 to 10 m sandy rock. SPT test results obtained values of 12 at depths of 0 to 2.5 m, at depths of 2.5 to 3.4 m are 40 and at depths of 4 to 10 m are 43-50. Based on laboratory tests, the following soil characteristics were obtained: the moisture content at a depth of 1 m is 39.65% and at a depth of 5 m is 15.39%. Specific gravity at a depth of 1 m = 2.778, at a depth of 5 m = 2.543. Compressive strength 0.310 kg/cm2 and cohesion 0.155 kg/cm2 at a depth of 1 m. Direct shear strength at a depth of 5 m, cohesion of 0.00 kg/cm2 and shear angle of 35.30°. The results of the filter analysis for sample tests at a depth of 1 m were 80.69% clay, 13.96% silt, 5.05% fine sand, and 0.40% medium sand. At a depth of 5 m is loam + silt 29.80%, fine sand 22.47%, medium sand 25.25%, coarse sand 8.08%, and small gravel 14.39%.
