Abstract

In this study, an analysis was conducted on the influence of the number of compaction impacts on the density of asphalt mixtures using the Marshall method on Hot Rolled Sheet Wearing Course (HRS-WC) Thin Asphalt Concrete (Lataston) mixture. The main objective of this research is to compare the compaction results between manual and electric methods. To achieve this, variations in the number of impacts were performed, namely 2 x 25, 2 x 40, 2 x 50, 2 x 60, and 2 x 75 impacts. The research results showed a significant difference between the manual and electric compaction methods in the observed Marshall parameters. Especially with 2 x 75 impacts, a noticeable difference was observed with a stability difference percentage of up to 2.505%. Therefore, it can be concluded that although the manual and electric compaction methods yield relatively similar results in terms of Void In Mix (VIM), Void In Material Aggregate (VMA), and Void Filled With Bitumen (VFB), there is a significant difference in stability, flow, and Marshall Quotient (MQ) parameters. This research has important implications in asphalt compaction practice and can be used as a guideline for selecting the most suitable compaction method to produce optimal quality asphalt mixtures.

Abstract

Along with the development of micro-hydro power plants, machines with very heavy weights are needed, therefore a special foundation is needed that can support the weight of the machine in an active or inactive state. Machine foundations are different from foundations in general, machine foundations require dynamic analysis, namely when the machine is operating, in this study four foundation calculations are taken into account, namely foundations P1, P2, P3 and P4, foundation P1 has dimensions of 10 m long, 3.5 m wide and 2.2 m high, P2 foundation is by widening 2 m, so that the width changes to 5.5 m, as well as for the P3 foundation, namely by extending 2m, so that the dimensions are 12 m long, and for the P4 foundation, by extending and widening 2m, so that the dimensions are 12 m long and 5.5 m wide. The results of the calculation of the static load, the foundations P1 to P4 meet the requirements because the load received by the foundation is 394.66 kN or 39,466 tons, while the carrying capacity exceeds the load, namely 138.13 tons, 217.06 tons, 165.75 tons and 260.7 tons, based on the comparison between the weight of the machine and foundation weight > 3 means that it meets the requirements for the magnitude of the ratio, 4.68, 7.36, 5.62 and 8.83. In addition to static loads, in the planning of machine foundations that need to be checked, namely dynamic loads, namely the value of the ratio of frequency and natural frequencies, the value cannot be less than 1, foundations P1 to P4 have a value of more than 1, which is equal to 1.16, 1.31, 1.22 , and 1.37 for the horizontal direction and 1.14, 1.28, 1.16 and 1.31 for the vertical direction, for the magnification factor value the value must be below 1.5, all foundation models meet the requirements, namely the values ​​are 1.44, 1.25, 1.36 and 1.18 for the horizontal direction and 0.88, 0.76, 0.82, and 0.72 for the vertical direction. And what is very important in foundation planning is determining the comfort of workers, foundation P1, is included in Limit Form Machines And, meaning that it is not recommended because it is included in danger to structures, foundations P2, P2 and P3 are included in Trobele some to persons (quite disturbing), foundation P3 is not optimal because the max displacement is only 0.40 inc, type P2 is more effective, namely only by widening the foundation the value drops to 0.38 inc from the previous 0.41 inc on the P1 foundation, while P4 even though the value is 0.38 inc but the dimensions of length and width are larger.

Abstract

The rapid development of technology is directly proportional to the request of the project owner to complete the work in a fairly short time. This study aims to find the dimensions and amount of reinforcement, as well as the quality of concrete that meets. The dimensions of the tank in this study have a diameter of 17.66 m and a height of 10.965 m with a planned capacity of 2,500 m3. While the planned pile cap dimensions are 19.47 m in diameter with a planned thickness of 40 cm. The planning standard used is API 650 of 2019 published by the American Petrolium Institute. Meanwhile, the repetition that is not in API 650 is determined based on SNI 1727:2020 and pile cap repetition using SNI 2847:2019. The software used is STAAD Pro Connect Edtion v.22. As for the calculation of strouss foundation repetition using PCA COLUMN v6.0. From the planning calculations, it can be determined that the double repetition for the pile cap is D16-150 (thread reinforcement diameter 16 mm, distance 150 mm) with (f'c) = 29.05 Mpa (concrete K-350), (fy) = 320 Mpa, and concrete blanket thickness 70 mm. Meanwhile, for the strouss foundation, 18D16 main reinforcement is evenly distributed on all sides of the circle with a minimum distance of 65 mm and a minimum concrete blanket thickness of 60 mm.

Abstract

Earthquakes are natural phenomena that can cause building collapse and loss of life. During an earthquake, buildings standing on the ground will experience movement at its base, the acceleration arising from ground motion will cause horizontal / lateral inertial forces on the mass of the structure, then used as a plan earthquake force that must be reviewed in planning. According to article 7.8 of SNI 1726:2019, the seismic base shear force is the product of the seismic response coefficient (Cs) and the building's seismic weight (W). The seismic response coefficient must be determined by the spectral acceleration parameter (SDS) which is highly dependent on the site class classification regulated in Article 5 of SNI 1726:2019, which uses the top 30 m layer profile data from the soil investigation. This study uses a 1-span reinforced concrete frame with 3 floors and 20 locations spread across Kupang City to see the effect of site class on the magnitude of seismic base shear force. The results showed that the base shear force of SC site increased by 87.5% against SB site, the base shear force of SD site increased by 9.22% against SC then the shear force of SE site decreased by 1.94%..

Abstract

The hot mix asphalt-aggregate mixture in the construction of asphalt concrete roads generally consists of three layers: the base layer, intermediate layer, and surface layer placed on a granular subbase. One of the asphalt concrete layers is the Intermediate Layer, which is a hot asphalt mixture consisting of aggregate, asphalt material, and filler mixed at a central mixing plant. The resulting mixture is spread and compacted on the Aggregate Base Layer. The hot asphalt mixture is designed according to the General Specifications for Road and Bridge Construction by the Directorate General of Highways in 2018 (Revision 3) to ensure that the design assumptions regarding Asphalt Content, Air Voids, Stability, Flexibility, and Durability are in line with the planned traffic. Research results indicate differences in Marshall characteristics from Marshall test results for the Intermediate Layer asphalt concrete mixture (AC-BC) of the two compositions. Almost all Marshall properties meet the Directorate General of Highways specifications in 2018 Revision 3, except for Flow with a particle size of 19 mm, which does not meet the specified flow range of 2 – 4 mm, and Marshall Stability for Aggregate Residue with a particle size of 19 mm, which does not meet the specified minimum of 90%. Meanwhile, the Optimum Asphalt Content (OAC) values for Aggregate with a particle size of 25 mm are 5.11%, and for Aggregate with a particle size of 19 mm, it is 5.18%.

Abstract

Development of socio-economic activities occurs linearly with respect to the road network. Along the edge of the Timor Raya Timor Raya road Km 8+800 to Km 9+000 the side barriers are now getting higher, both due to vehicle parking on the road body, as well as due to vehicles entering and leaving the parcel (access) and pedestrians on the shoulder of the road and road crossings. Traffic problems that arise due to the activity of vehicles parked on the road are of course detrimental to road users such as when the vehicle is parked or when the vehicle exits the parking lot, therefore parking controls on the Timor Raya road Km 8+800 to Km 9+000 is the most important thing to do to control traffic so that congestion, pollution, noise can be minimized. Based on the analysis conducted using the Indonesian Highway Capacity Manual (MKJI, 1997). It is known that the peak volume occurred on Monday, 08 May 2023 at 17.30-18.30 WITA with a volume of 2162.75 PCU/hour, a capacity of 2366.63 PCU/hour, and the performance of Jalan Timor Raya, Oesapa Km 8+800 to Km 9+ 000, is at service level E with a DS value of 0.91. with a light vehicle free flow speed of 35.8 km/hour and an average speed of 22 km/hour. in conditions without light vehicle (LV) and heavy vehicle (HV) parking on the road, enter service level D where the DS value reaches 0.78, with a capacity of 2781.83 pcu/hour, free flow speed of light vehicles 38.9 km/hour and an average speed of 28 km/hour. Whereas in conditions without parking at the entrance to the service level C where the DS value reaches 0.71, with a capacity of 3019.31 pcu/hour, the free flow speed of light vehicles is 42.6 km/hour and the average speed is 32 km /hour.

Abstract

Rainwater Harvesting System (RWHS) is a simple concept for utilizing water resources, by collecting rainwater that falls in the roof and channeling it into a reservoir. Non domestic water needs in school buildings are needed in large quantities considering the large number of water users. With the RWHS concept, it is hoped that it can provide an alternative solution for using rainwater at SMA Negeri 1 Taebenu. Basen on the results of the water balance analysis at SMA Negeri 1 Taebenu, the water deficit was greatest in Juli at 0,61 liters/s. Based on these values, 2 rainwater storage tanks are planned with a capacity of 4,5 m3 each with dimensions of 1,5 x 1,5 x 2 meters. The storage tank is designed to be below groung level due to limited land. Rainwater is only used for bathroom purposes and watering plants, so the design of the reservoir is made simple, just using a dirt filter in the gutter to dispel dirt carried from the roof into the tank.
