Abstract

Roads are the infrastructure that sustains the growth of the economy and plays a very important role in the progress and development of a region. Asphalt functions as a binder in asphalt mixes, making it important to maintain its stickiness, softness, and pliability. Adding additives to asphalt is an alternative that can be used to maintain or increase the grip, soft point, and flexibility of the asphalt. Used motor vehicle tires are made from a variety of materials such as natural rubber, neoprene, chemicals, carbon black and certain oils. The characteristic of rubber is that it is durable and flexible or elastic. This study aimed to determine the value of Optimum Asphalt Content (KAO) in AC-WC mix using modified bitumen with wheel powder with 1% and 2% variations. The results of this study show the results of parametric data analysis for each KAO that the optimum value of the 3 KAOs is 6.18% with the addition of 1% asphalt + rubber tire powder. The parameter values are VIM 4.61%, VMA 18.52%, VFA 75.31%, Stability 1459 kg, and Flow 2.95 mm.

Abstract

Refrigerated LPG Terminal is a facility that handles liquefied gas as a raw material, ensuring a reliable supply of LPG for the community. Located in Remen Village, Jenu Subdistrict, Tuban Regency. The intensity of land use changes in an area will correspond to changes in the transportation system in that area. The construction of an LPG terminal will undoubtedly have transportation-related impacts in the area. Therefore, efforts are needed to address these issues by formulating traffic engineering management that is tailored to the actual conditions. The method used involves observational surveys such as Trips Attraction Survey and Origin Survey, which focus on inventorying the roads around the construction area. The impact analysis method of development using MKJI is employed. The analysis of the impact of the development of PT. Pertamina LPG terminal shows that from the existing condition before the development, during the construction phase, and at the early operation stage, it does not significantly affect the capacity of the existing roads in the area. In the forecast period of the next 5 years, there will be an increase in the road capacity value of DJ during the morning peak from 0.248 to 0.334. Regarding the level of service (LOS), it remains at level B for the existing period, construction phase, and early operational stage. By analyzing using forecasting methods, alternatives that can be planned include traffic control systems, understanding the road network system around the area, providing public transportation, installing traffic signs, providing parking facilities, and minimizing roadside parking.

Abstract

Indonesia's geographical location makes Indonesia as a country prone to earthquake risks, both tectonic as well as volcanic. The Indonesian National Standard (SNI) 1729:2015 requires bolt connections for steel buildings with a height of more than 38 m must use high-strength bolts (HSB) with pre-tensioning. Snug-tight and pre-tensioned bolted connections are physically no different. Differences will occur when the connection is loaded, namely for pre-tensioned joints, where slip between the plates being joined as a result of the bolt hole size being larger than the bolt diameter will occur when the slip limit strength is exceeded. This study aims to observe the strength and behavior of pre-tensioned bolted joints with increasing loads. The analysis was carried out according to SNI 1729:2015, with data validation through experimental tests using BJ37 plate specimens loaded with concentric axial tension. The connection uses a HSB-A325 M12 standard hole with class A surface preparation. Pre-tension bolts are applied by turn-of-nut. The test results show that the strength of the slip limit (Pslip) is 37.998 kN; this value is 5.7% higher than the analytical result of 35.94 kN. After reaching the slip limit strength, the connection can still accept the load with the bearing force transfer mechanism and reach the connection limit strength (Pu) of 50.197 kN, 32% exceeding the slip limit strength. Turn-of-nut, one of the methods recommended by SNI 1729:2015, is a fairly simple method for pre-tensioning because no special additional tools are required and the required minimum pre-tensioning force can be met by achieving Pslip experimental results not lower than the results of the analysis.

Abstract

Benanga Dam is a construction to contain the discharge and store water at Lempake, Samarinda, East Kalimantan. At the beginning of the construction, the capacity is 1.6 million m3 but capacity shrunk until 500.000 m3. Overflow around the dam area, often causes flooding at the Bengkuring’s region. This study aims to determine effect of brick substitution on asphalt pavement in Benanga Dam water. If pavement is submerged, so pavement’s void will fill up water, dissolve materials and decrease pavement quality. The use of bricks to utilize renovation waste and as a substitute for Portland cement because it has pozzolanic properties. Research was conducted by experimental using asphalt Pen 60/70, used coarse and fine aggregate from Palu, consists of 2 variables are 0% and 100% of brick filler. Asphalt concrete mix standard refers to Bina Marga, 2018 and analysis using Marshall method. In this study, innovations used 5.5% of asphalt and 100% of brick have a strength up to 3,190.7 kg and decrease around 5 cm. That asphalt mixture is able to withstand largest traffic load and smaller decrease compared to other mixtures. The Void Filled with Asphalt (VFWA) is 72,7% which is attain requirements and efficient, so the pavement doesn’t have cavity and watertight.  Asphalt mixture minimized the occurrence of damage when submerged by flood.

Abstract

One of the water management efforts that can be done is the construction of a weir. Aspects that need to be considered in the planning and construction of a weir are capacity and stability. Cipamingkis weir was built in 1980 and is a vital irrigation infrastructure because it irrigates ± 7.508 hectares of rice fields in Bogor Regency and Bekasi Regency. This study aims to determine the capacity of the weir and then calculate its stability condition. Through calculations, it is known that the stability of the weir during normal water level conditions is safe against overturning with a safety factor of 3,8 greater than 1,5 for overturning with earthquake and a safety factor of 10,8 greater than 1,5 for overturning without earthquake. Under normal water level conditions, the weir is known to be safe against shear with a factor of safety of 1,56 greater than 1,1 for shear with earthquake and a factor of safety of 2,99 greater than 1,3 for shear without earthquake. Under flood water conditions, the stability of the weir is safe against overturning with a factor of safety of 1.67 greater than 1,5 for overturning with earthquake and a factor of safety of 2,38 greater than 1,5 for overturning without earthquake. Likewise, the stability of the weir against shear is known to be safe with a factor of safety of 1,68 greater than 1,1 for shear with earthquake and a factor of safety of 3,11 greater than 1,3 for shear without earthquake. The capacity of the weir using the 50-year return period is 1647,44 m3/sec as the ideal design discharge and for the 100-year return period is 1859,36 m3/sec.

Abstract

Some residents in the Singosari District, Malang Regency use the potential of springs as raw water for drinking water. One of the main aspects that must be considered in exploiting the potential of springs is the feasibility of the quality of the water. The quality of the water used by residents is not necessarily identified. This research was carried out with the aim of providing an assessment of the feasibility of water quality from springs as a source of raw water for drinking water. The object of this research was 12 springs spread across the Singosari District. Physico-chemical parameters used as the basis for assessing water quality include pH, TDS, nitrate (NO3–), turbidity, iron (Fe), chloride (Cl–), manganese (Mn), sulfate (SO42–), ammonia (NH3), and sodium (Na+). The water quality from springs is assessed by using a water quality index model. The water quality index value of the springs studied has a range of 8.80 – 41.13. There are 10 springs with very good water quality category and 2 springs with good water quality category.

Abstract

Brick is a common building material used by the community to make a building. However, not all of these bricks can be used if they do not match the size or are cracked or broken so that they become waste and cannot be recycled. This often happens and is left alone by the community so that sometimes it accumulates or is used as stockpile material. Therefore, it is necessary to research how the bricks that have become waste can be reused to be a substitute for fine aggregate in fc'20 quality concrete. The research was conducted at the Civil Engineering Laboratory of Bung Hatta University by experimenting with the design of fc'20 concrete mixtures with applicable standards. The variations in the design of the stone waste mixture were 0%, 13%, 14%, 15%, 16% and 17%. The compressive strength test for the quality of fc'20 was carried out at the age of 7 days, 14 days and 28 days. The results showed that at 7 days of age with 0% brick substitution, the concrete compressive strength was 13.16 MPa and 13.59 MPa at 14 days. It is estimated that at the age of 28 days it will produce a compressive strength of 20.90 MPa, successively with the composition of a mixture of bricks at 13%, 14%, 15%, 16% and 17% at the age of 7 days to produce a compressive strength of 13.59 MPa,13, 59 MPa, 14.58 MPa, 13.02 MPa, and 12.60 MPa. At the age of 14 days the compressive strength was 17.96 MPa, 18.12 MPa, 20.24 MPa, 19.82 MPa, and 19.25 MPa. At the age of 28 days, it is estimated that the compressive strength for fc'20 is 20.59 MPa, 23.00 MPa, 22.52 MPa, 22.84 MPa and 21.87 MPa. Based on these findings it was concluded that waste bricks can be used as a substitute for fine aggregate in the manufacture of concrete with the optimum composition at 14%. A mixture of brick waste that is still feasible to produce quality fc 20 concrete at a composition of 13%, 14%, 15% and 16%

Abstract

Cone Penetration Test field instrument, also commonly refered to as sondir, has been commonly used in Indonesia. However, the usage of Cone Penetration Test in combination with pore water measurement (CPTu) is not yet used widely, which is why this research is conducted in situ by using CPTu instrument. In situ testing has a few advantages, such as:soil parameters are obtained under actual stress conditions, continous data can be obtained along the depth of soil, and it overcomes sampling problems or sample interferences. Location of this research is in Gedebage area of Bandung which currently undergoes major development. Soil in the area are soft soils which commonly have low shear strength. Soft clay shear strength (Su) can be determined by the ratio of net cone resistance and conus factor (Nkt). Further research on Nkt coefficient on soft soil shear strength evaluation based on CPTu test results are going to be verified by using laboratory testing. The research shows that Nkt coefficient which are suitable for Gedebage area ranges from 13 - 15. Range of shear strength parameter based on the laboratory test and in situ CPTu test calculations are as the following: depth of 0-10 m Su >25 kPa, depth of 10 - 25m Su is around 10 kPa, and depth of 25 - 31m Su > 100 kPa.

Abstract

The demand for housing among the population is substantial, leading to the challenge of insufficient land area for construction. We construct residential developments horizontally to address this issue. However, the construction costs associated with this approach are significantly higher. As a result, there is a need for various efforts to optimize construction costs, and one such initiative involves the application of value engineering methods. The X Apartment Project in South Tangerang, with a construction value of Rp. 203,204,569,971, is the focus of this study. Based on the significant value of the development, this study seeks to estimate cost savings through value engineering analysis, particularly in the area of architectural work. This research method has four stages, namely the information stage, the speculation stage, the analysis stage, and the presentation stage. The observations lasted one month and were conducted using a questionnaire instrument. The Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method provides an alternative decision-making system. This study demonstrates that the application of value engineering reduced the initial cost of Rp. 203,204,569,971 to Rp. 201,685,400,449, with a reduction of 0.75% in window work (J1), glass door work (PL1), door work (PD1), light brick wall work, and homogenous tile KR2B floor tile work.
