Abstract

U-Turns are employed as a particular access for drivers who want to switch lanes while they're moving. However, the problem that often occurs is that this intersection can be the main cause of congestion on a road. In the case of the U-Turn intersection of Arterial Road Jl. Letjen Suprapto, to be exact, is across from SP Plaza Batu Aji. Traffic jams are often caused by this, especially in the afternoon during work hours. in accordance with the 1997 Indonesian Highway Capacity Manual, This study tries to evaluate the intersection's performance and determine whether it is the primary cause of persistent traffic congestion. The technique used to obtain data is observation and documenting. The results showed that the road capacity value was 2884.1 pcu/hour. Traffic volume value in the direction of Muka Kuning - Tg. Uncang of 1458.7 pcu/hour. 2475.4 pcu/hour in the opposite direction. 1033 vehicles were shown at 17:30-18:00 as making U-turns with an average travel time of 08'36". As a result of vehicles making u-turns, delays occur which hinder the passage of vehicles through the road segment resulting in congestion. This is the main cause of congestion on this road section with a road service value of 0.51 or a service level of C. These results indicate that the road segment is still stable, but vehicle speed is starting to be controlled. The research's conclusions can act as a guide for further investigation.

Abstract

Sidoarjo mudflow (Lusi) still occurs today, various efforts to stop and reduce the eruption have been made but have not stop able to stop the Sidoarjo mud. To help reduce the mud being ejected, it is necessary to utilize Sidoarjo mud. Researchers aim to reduce the mud caused by Sidoarjo mud by utilizing artificial materials as substitutes for natural materials. Utilization is also carried out for fly ash which is waste from the PLTU. Sidoarjo mud and fly ash are combined with an alkaline activator to form geopolymer paste and cement paste. The geopolymer paste specimen were tested for specific gravity of fine aggregate and its porosity. The result show Sidoarjo mud has a specific gravity of fine aggregate of 2.519 and fly ash of 2.525 which is greater than specific gracity of water, namely 1. The porosity of the geopolymer paste is 3% and that of cement paste is 3.8%.

Abstract

Damage that occurs in building structures is a problem that often occurs, especially damage to beams. Beams are a very important structural element in buildings. Collapse that occurs in beams is generally caused by shear forces, because collapse caused by shear forces occurs suddenly because concrete is brittle. Handling that can be done one of which can be done by handling the shear reinforcement in the beam with reinforcement so that the beam can withstand the working load. One of the methods used to overcome damage to beams is by providing strength or in the form of mixed materials in the form of flakes/iron filings. The purpose of this study was to determine the effect of beam strength on the shear capacity of reinforced concrete beams. The benefits of this research are expected to contribute to science, in particular to become recommendations for strengthening structures. 6 specimens were used with variations in tensile reinforcement and there were 3 beams that did not use iron flakes/fibers and 3 beams used flakes/iron filings reinforcement. Based on the results of the research obtained, the greater the value of the reinforcement ratio given, the greater the stiffness of the specimen, but the greater the value of the tensile reinforcement ratio given will not affect the shear capacity of a reinforced concrete beam.

Abstract

The use of artesian wells or drilled wells is still the main choice of the people of Cot Mee Village, one of the areas in Nagan Raya Regency, where this is done to meet the needs of raw water sources as domestic needs. In addition to the expensive cost of installing borewells, this also adversely affects the environment due to excessive use of groundwater and raises the potensial for land subsidence. Under these circumstances, in order to solve the problem of raw water for individual lives, alternative solutions are needed that are more effective and efficient. One of alternative is to create a rainwater harvesting system from the roof of the building by maximizing high rainfall or known as rainwater harvesting technique. Field studies show the building area in Cot Mee Village is currently in good condition and livable and the entire roof is made of zinc. Of course, this condition will be very maximum in the process of harvesting rainwater. Analysis of the potensial for rain harvesting in Cot Mee Village is 64,685.61 liters/day, with the potential for rainwater harvesting per house of 743,512 liters/day. The ratio between the total water harvested amounted to 64,685.61 liters/day with the total use of raw water for needs of the people of Cot Mee Village of 43,399.8 liters/day. Research shows that rainwater harvesting technique will be adequate and able to be an alternative in providing raw water for domestic needs.

Abstract

PET (Polyethylene Terephthalate) plastic cannot be separated from everyday life, as is commonly found in bottles. The increasing use of plastic, if not managed and utilized correctly, will cause harm to the environment. On the other hand, Indonesia is rated first as a palm-producing country. Unfortunately, its become a new problem due to the waste generated. POFA (Palm Oil Fuel Ash) is palm oil waste in the form of grayish-black fine granules resulting from burning palm oil at a temperature of 800 – 1000°C. POFA waste management is needed so that it does not only become waste but has added value. In addition, the high demand for asphalt mixtures requires innovations to improve the characteristics of asphalt mixtures, such as utilizing PET and POFA waste as additives in asphalt mixtures. This research aimed to determine the marshall parameters of the AC-WC mixture added with PET and POFA, obtain the KAO value (Optimum Asphalt Content), and look for the cost efficiency of the AC-WC mixture. This study designed 45 samples with details of 15 samples to obtain the KAO value and 30 samples to determine the optimum PET content varying from 1%, 2%, and 3%, along with POFA 50% and 100 %. These samples were tested using the Marshall test referring to SNI 2489-2018. This study found that the percentage of 1% and 2% PET met the requirements of the 2018 General Specification Revision 2 with the optimum percentage of adding 2% PET plastic and 50% POFA substitution.

Abstract

Contractor selection plays a vital role in project management, where factors such as cost, quality, and time must be carefully considered. This study presents an innovative approach to optimize contractor selection using an AI-driven method based on Particle Swarm Optimization (PSO). The objective is to achieve the best possible selection of contractors by considering multiple criteria simultaneously. Real-world data on cost estimates, quality scores, and project times are collected and normalized for fair comparison. The PSO algorithm is utilized to search for the optimal combination of contractors that minimizes cost, maximizes quality, and minimizes project time. The proposed weighted objective function evaluates the performance of each contractor based on the selected criteria. The results demonstrate the effectiveness of the AI-driven PSO method in achieving optimal contractor selection. The findings highlight the potential of using AI techniques for decision-making in project management, enabling project stakeholders to make informed and data-driven contractor selection decisions. This research contributes to the growing body of knowledge on AI applications in project management and provides practical insights for project managers and stakeholders involved in contractor selection processes.

Abstract

In fact, traffic accidents are a routine occurrence in the world and are one of the biggest causes of death in the world. Based on data obtained by WHO, traffic accidents cause 1.2 million deaths per year in low and middle income countries. 1000 deaths per day for under the age of 25 in the world so that traffic accidents are the highest cause of death for the category of children and adolescents in the age range of 5 to 29 years. However, one thing that is of concern is how to change the societal paradigm of traffic behavior so as to foster a culture of safety, especially from an early age. One of the strategic steps is through outreach to students from Kindergarten, Elementary, Middle School to SMA/SMK levels. The community service program is carried out at Pembangunan Jaya Middle School, located on Jl. Bintaro Utama 3A Pondok Karya Village, Pondok Aren sub-district, South Tangerang city. In socialization activities carried out at the initial stage and at the final stage by distributing pretest and posttest, of course this serves to find out the understanding of the material conveyed by the resource persons. Data processing from pretest and posttest results using IBM SPSS assistance by testing several testers. Of course, it is hoped that the results of the test will show understanding from the students of SMP Pembangunan Jaya so that later it can raise awareness about improving safety. Based on the results of the paired samples t test analysis using IBM SPSS in Figure 5, p = 0.00 (p <0.05), so that Ha is accepted and H0 is rejected, meaning that there is a significant influence on the socialization activities to raise awareness on road safety in Generation Z especially on the theme of Attitude towards Safety Riding.

Abstract

Cengklik Reservoir is one of the tourist attractions in the Boyolali area. Functionally, the Cengklik reservoir is used as a water reservoir or storage area as well as a source of water for the needs of the surrounding community and to supply rice fields. Based on observations, the reservoir has decreased in function, namely seepage is found. One of the methods applied for the handling of seepage is the foundation structure in the form of a diaphragm wall. Observations were started by collecting data (pumping test data and drawings of the diaphragm wall structure). The results obtained for the total diaphragm wall foundation with a depth of 16 m with a depth of excavated soil of 16 m. Specifications for the diaphragm wall plan with a land area of 375m. Diaphragma wall (slurry wall) is a type of plastic concrete retaining wall with a foundation that has very strong rigidity, low vibration during construction, and has a waterproof function. Diaphragama wall provides less seepage effect than other methods such as secant pile. The secant pile only has the same use but differs in area. Cut off wall is a method of excavation work, surrounded by excavated land such as a guide wall. Insulation or retaining water flow on large dam foundations is usually done by the Cut of wall method. This method is suitable for excavation work which is quite deep and dense soil area
