Abstract

The conversion of agricultural land in urban areas has resulted in increasingly narrow agricultural land and many irrigation networks are not functioning. This has resulted in many isolated lands that cannot even be served by irrigation, so that the alternative source of agricultural water is local shallow ground well water. With the potential of water sources and limited land area, farming is expected to utilize water efficiently. Small sprinkler irrigation systems such as the 24D Netafim on the market, are expected to be an alternative in providing irrigation and for that it is necessary to test the ability of the irrigation system on the irrigation radius and its uniformity at a duration of 15 minutes. The test results showed that the irrigation uniformity was above 85% at the distance between sprinklers 4.5 m, 5 m and 5.5 m and 6 m with a stick height of 0.5 m and 0.75 m. For stick heights of 1.0 m and 1.25 m at the same sprinkler distance, the uniformity coefficient is less than 85%. While the optimal irrigation radius obtained at a sprinkler distance of 4.5 m, 5 m and 5.5 m is an average of 5.6 m.

Abstract

In steel construction the selection of types and installation details of connection is an important thing that cannot be ignored. There are three types of steel connections, namely bolts, welds, and rivets. Welding connections have a good strength if conducted in proper quality control. In addition, these connections are also inexpensive and easy to implement. The focus of this study is the modelling of welding connections which can produce outputs that are close to the experimental results. The modelling is done by using finite element program. There are two models carried out; Model-1 uses tie constraint interaction type, meanwhile Model-2 uses merge and chamfer type. Results show that Model-2 is closer to the experimental result with an accuracy of 97.75% for its ultimate load. The deformation that occurred in Model-2 also resembles the experiment deformation. In terms of energy dissipation, the experimental result is 78,036.396 kN.mm while the result of Model-2 is 94,456.982 kN.mm. Thus, the accuracy level of Model-2 is 82.62%.

Abstract

Peat soil is one type of subgrade that is not good for road construction. Peat soil has a low bearing capacity which is indicated by a low CBR value. The embankment on peat is needed to increase the CBR value, but compaction and spreading are difficult to do. Therefore, it is necessary to strengthen the combination of bamboo grids and concrete piles. The purpose of this study was to determine the potential for increasing CBR of embankment reinforced on peat soil. The research was conducted through a series of model tests in a test box filled with peat soil with and without bamboo grid reinforcement and a combination of bamboo grid and concrete piles. The CBR test was carried out on the embankment which was differentiated based on the thickness of 0-15 cm. The results showed that reinforcement can increase the CBR value of the embankment soil on peat soil. The results of the analysis for the embankment thickness of 3.93 m, the combination of bamboo grid reinforcement and concrete piles has the potential to increase the CBR value by 183% (from 5% to 14.15%) and bamboo grid reinforcement by 32% (from 5% to 6.6%).

Abstract

As many as 33% of vehicle ownership in Bali Province in 2019 was in Denpasar City, coupled with the passing of vehicles from outside the city to work and recreation to burden the road network in Denpasar City. This causes problems in the transportation system that affects the performance of the road network, especially the performance of signalized intersection in Denpasar City. The performance of the signalized intersection is affected by the capacity of the approach where one of the factors that affect it is saturation flow. This study aims to find out the comparison of saturation flow in protected and opposed approach between the IHCM and Time Slice Method. The saturation flow result in the protected approach in Simpang Subita based on IHCM is 3,629 pcu/green hours greater than 71.18% compared to the Time Slice Method which is 2,120 pcu/green hours, while the saturation flow result in the opposed approach in Simpang Waribang based on IHCM is 1,857 pcu/green hour smaller than 37.49% compared to the Time Slice Method which is 2,971 pcu/green hour.

Abstract

Glass is an object that cannot be separated from human life. Based on data from the Minister of Environment and Forestry (LHK) in 2020, it was stated that data on waste in Indonesia reached 67.8 million tons, of which 0.7 million tons were glass waste. It is known that the types of waste produced in Indonesia are organic waste (60%), plastic waste (14%), paper waste (9%), metal (4.3%), glass and wood (12.7%). The purpose of this study was "to know the effect of adding glass waste powder and bamboo leaf ash on the performance of paving blocks". The data needed in this study are primary data and secondary data. The technique used to collect primary data in this research is the experimental method. The data to be analyzed was obtained from the results of testing in the laboratory using 45 samples. Data were analyzed using multiple linear regression test. All analysis using SPSS software which is then presented in the form of tables, pictures and descriptions. The results showed that the average compressive strength of paving blocks was B quality with regression equation Y = 19.010+ (-0.119) X1 + (0.063) X2, while for absorption was D quality with regression equation Y = 10.598+ (-0.094) X1 + (-0.001) X2. In general, the addition of glass waste and bamboo leaf ash has an effect on the compressive strength and water absorption of paving blocks.
