Abstract

Manggarai Station is planned to be central of public transportation in Jakarta. Commuter line or known as KRL is one of the modes offered at the station and has served trips and become a favorite mode of Jabodetabek commuters. The planning requires a switchover transition, which impacts Manggarai Station in the form of changes in routes and infrastructure. This also has an impact on commuter travel behavior. This study aims to identify variables that relate and affect commuter travel behavior towards changes at Manggarai Station. Methods were conducted with chi-square and multinomial logit analysis on a sample of 400 commuters through questionnaire data. The results show that the factors associated with changes in passenger behavior are marital status, education, income, location of residence, number of cars and motorbike owned, origin station, alternative modes used, destination line, transit frequency, travel frequency, waiting time, overall travel time, KRL travel time, mode used and changes in other passenger behavior. In addition, factors that have a significant effect of 34.6% on changes in commuter travel behavior are the location of residence (Bogor City), origin station (Cilebut Station and Bojong Gede Station), the mode used (public transportation), KRL travel time (100-199 minutes) and awareness of changes in other passenger behavior. Meanwhile, the other 65.4% is influenced by independent variables outside the study.

Abstract

The use of plastic in the city of Balikpapan in currently often used in daily activities, causing plastic waste in the city of Balikpapan to contribute up to 17% of the total waste production. The use of plastic in the world of construction has begun by using PET (Polyethylene Terephthalate) plastic as a concrete mixture. With its utilization, it can be a solution to reduce the production of plastic waste in the city of Balikpapan. In this research, PET plastic was used as a concrete mixture with a percentage of 0.7% and combined with local materials from East Kalimantan as a form of supporting the relocation of the state capital to East Kalimantan province. The purpose of this study was to determine the effect of using PET type plastic as fine aggregate on the flexural strength of concrete. The method used in this study is the experimental method with a test sample measuring 15x15x60 cm. The test results showed that normal concrete got a slump value of 10 cm and the PET variation was 7% 9 cm with the flexural strength test results of normal concrete with a curing period of 14 and 28 days getting a value of 3,044 MPa and 3,188 MPa, PET variations of 0.7% 14 and 28 days got a value of 2,370 MPa and 2,423 MPa, based on the results of this study it can be concluded that the use of PET plastic as fine aggregate experienced a decrease in the quality and weight of the sample due to the smooth and slippery texture of PET plastic causing the concrete mixing process to be poor.

Abstract

The high use of private vehicles in big cities, including the city of Bandung, also increases negative impacts, one of which is congestion. For this reason, it is necessary to limit private vehicles so that negative impacts can be reduced. One of them is by carrying out odd-even trials in the city of Bandung, to determine the impact on transportation conditions. Literature studies show that odd-even can reduce travel time, reduce vehicle volume, increase vehicle speed, and reduce pollution levels. Some countries that have implemented odd-even have felt a positive impact, but there are also those who have felt the opposite. Referring to the success of several cities, including the city of Jakarta, odd-even will also be tested on several roads in the study area. This research aims to determine the percentage of people's mode choices and changes in road network performance when odd-even is implemented. The method in this research is quantitative based on questionnaires from people who actively pass through the road sections affected by the trial. The results show that people still tend to use private vehicles compared to public transportation. Apart from that, there were visible changes in road performance, where there was a decrease in vehicle volume by 30% and a decrease in travel time of around 17-25 seconds per section on the road tested.

Abstract

Blood clam is a popular shellfish in Indonesia. Especially in Langsa because it is close to the sea area, blood cockles are found in large numbers which produce waste in the form of shells in large quantities. However, blood cockle shells contain calcium carbonate (CaCO3), which functions to bind water because water is the enemy of asphalt which can affect the age of asphalt, so the ash of blood cockle shells can be used as a filler. The aim of this test is to determine the stability and durability values due to the effect of adding blood cockle shell ash content as an additive to filler with blood cockle shell ash content of 0%, 30%, 50%, 70% and 100 %. The method used is the experimental method, namely experimental activities to obtain data. In this study, the addition of blood cockle shell ash as an added filler to the AC-WC asphalt mixture on the Marshall value showed that the greatest stability value was at 30 minutes of immersion, namely at a percentage of 50%, 1557.93 kg and the greatest stability value was at 8 hours of immersion, namely at a percentage of 50% it is 1404.40 kg. In this study, durability values were obtained based on the analysis results that at variations of 0%, 30% and 50% blood cockle shell ash content as a filler additive had the best durability values with values of 93.30%, 92.42% and 90.15% above 90% in accordance with the specifications required by the Department of Highways 2010.

Abstract

The existence of shuttle public transportation will result in a decrease in revenue from bus public transportation. Studying the level of influence of factors that influence the characteristics of the choice of transportation mode between bus public transportation and shuttle public transportation, especially in Sumedang Regency, reviewing simulations of changes in travel costs to determine the relationship between travel costs and levels. possibilities in choosing bus and shuttle public transportation. In this research, it can be concluded that the simplification of variables uses a simple correlation method and uses a stepwise method. Based on the calculation of the average level of probability of selecting shuttle and public bus modes, if shuttle and public buses serve the Sumedang - Jakarta route then the probability level of selecting shuttle mode is 51 % and public bus mode 49% with an average cost difference that is not too significant at Rp. 35,000 to Rp. 50,000,-. So in this research travel time and waiting time for departure are factors to consider in choosing public transport modes. On the Sumedang - Jakarta route or vice versa, the shuttle crosses the Cisumdawu Toll Road which connects Sumedang City - Cileunyi Bandung Toll Road and the MBZ Sheikh Mohammed Bin Zayed Flyover Toll Road which connects the Cikampek - Jakarta Toll Road, so the travel time on the Sumedang - Jakarta route is shorter using the shuttle. , while public buses are not allowed to cross the MBZ Elevated Toll Road. The study only analyzes the mode choice between bus and shuttle public transportation for the Sumedang – Jakarta route. The scope of this study can be expanded for passenger movements on other routes and competition for other modes.

Abstract

Domestic wastewater contributes 60% of water pollution, mainly due to households dumping their wastewater into drainage channels. Domestic wastewater contains organic and inorganic pollutants such as BOD, COD, TSS, and ammonia. Biological treatment can reduce the pollutant levels in domestic wastewater by using microalgae Chlorella sp. in suspension and attached to form biofilm on MBBR.. The research aims to examine and determine the effectiveness of MBBR with microalgae Chlorella sp. in domestic wastewater treatment. The research focuses on the role of microalgae biofilm in reducing ammonia concentration in domestic wastewater. The research uses MBBR with different volumes of kaldnes 3 media (10%, 20%, and 30%) and different retention times (8 hours, 24 hours, 60 hours, and 120 hours). The highest biofilm formation of microalgae Chlorella sp. occurred in reactor C7 (kaldnes 20%) with an initial cell density 10.630x104 cells/mL at a retention time of 60 hours (2.5 days). The reactors with microalgae Chlorella sp. had the best ammonia removal ability compared to the control reactors. The highest removal was in reactor C7 (kaldnes 20%) with 98.84% removal and 0.048 mg/L residual ammonia at a retention time of 60 hours (2.5 days). Microalgae Chlorella sp. can oxidize ammonia to nitrate through nitrification process involving Nitrosomonas and Nitrobacter bacteria.
