The total population is 12 specimens with a sample of compressive strength 5 specimens and split tensile strength 4 specimens for each treatment which is a random sample, i.e.: A (reference concrete); B, C, D, and E for concrete with 2% fiber and L/D ratio of 50; 62.5; 75 and 87.5. The test results of concrete materials meet the SNI. The significance level of 0.05 indicates that the test data are normal distribution and uniform. The hypothesis result shows that there is a difference between the reference concrete and the concrete fiber with variations L/D. The unit weight of concrete between the reference concrete and the concrete with variations of L/D is slightly different. The slump value decreases with the L/D ratio. Characteristics of the concrete increase up to L/D 75. Based on the design of K-200 concrete per-as Permen PUPR No. 28/PRT/M/2016 article B.06, compressive strength, split tensile strength, and flexural strength for reference concrete are 17,316 MPa, 2,317 MPa, and 3,083 MPa, greater than 35,9%, 43,8%, and 28,7% of design.

The existence of the Titab Dam is accompanied by the development of activities of the surrounding community, both tourism, economic and daily activities. Unfortunately, this activity in the future will have a negative impact on the condition of the dam so that it poses a risk. This study aims to determine the amount of sediment inflow with land erosion approach at the Titab Dam using the USLE (Universal Soil Loss Equation) method. Erosion rate prediction was carried out using the USLE method and with the help of ArcGIS 10.8 software. From the results of the analysis, it was found that in the Titab Dam catchment area, only 3 classes were obtained. The results of the calculation of the erosion rate using the USLE method showed that the magnitude of the erosion was 439,962 tons/year or 53.05 tons/ha/year. In addition, the most influential factors on the rate of erosion are the length and slope factors. In addition, land cover is also one of the most influential factors.","PeriodicalId":34836,"journal":{"name":"Prokons","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73353849","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the scope works in spillway model is a carrier channel downstream of the spillway which is 360 m long. To overcome the scour that occurs in the carrier channel downstream of the spillway, in the 4th series test, a groundsill structure was installed as a basic stabilizer for the carrier channel. The method is used in modelling include physical modelling, drainage testing, and observation of water flow and scouring that occurs at the bottom of the channel. The carrier channel groove model and the groundsill structure are made with a 1:40 scale both upright and flat (without distortion). The model test shows that the water flow in the carrier channel upstream of the groundsill is even and uniform with the bottom material of the channel not moving. At the bottom of the channel on the outer side of the bend which is assumed to be granular material, it is scoured to a depth of 2.68 m on the Z9 profile.
