Abstract

One of the negative impacts of transportation problems is congestion. Traffic congestion in urban areas is gradually becoming an important social and economic problem that needs to be addressed. Tangerang City is one of the supporting cities for the Jakarta metropolitan area as well as an area with a significant increase in population and vehicles, resulting in an increase in the number of people's movements or mobility in order to meet the needs of life. Meanwhile, the length of roads in Tangerang City during 2018-2019 did not increase and it is possible that there will be an imbalance between movement and available road capacity or minimal accessibility. The research approach used is quantitative with primary data sources obtained from closed questionnaire instruments from 180 road user respondents at the TangCity Mall intersection, Tangerang City. Analysis of the data used is a structural equation model with the AMOS 22.00 program to determine the factors that influence the impact of congestion. The results of the analysis show that the factors that most influence the impact of congestion are decreased concentration and loss of energy during traffic jams, which are more common in men who are married at the age of over 35 years, with a diploma level of education, as well as the type of work as a Civil Servant.

Abstract

The city of Bogor has varied contours and high rainfall. Potential natural disasters that often occur include floods, landslides, collapsed buildings, fires, landslides, hurricanes, earthquakes, and landslides. The city of Bogor is included in the zone 4 earthquake. Buildings in the Ibn Khaldun University (UIKA) Bogor were erected vertically as an optimization of limited land. The study of the vulnerability of buildings to earthquakes is very important to ensure that building users are in a safe condition during the service life of buildings against earthquakes using the Rapid Visual Screening (RVS) Method and the Hazus Method. The RVS form is obtained from the design spectra and the response spectrum, namely the high seismicity level based on the building coordinates. Based on the results of the RVS, the value of the vulnerability of buildings in the UIKA Bogor environment is 0.086% with an average value of 3.156. Based on the inspection that has been carried out, the buildings are classified as C1 and S1 building types, vertical irregularities occur in 3 buildings, plan irregularities occur in 1 building out of a total of 9 buildings and the land is assumed to be medium soil (type D) because there is no soil investigation.

Abstract

Depok City has traffic movement characteristics that are no different from other cities. Traffic movements in Depok City are quite busy and even tend to be congested at certain hours, such as when people go to work and return from work as happened on Arif Rahman Hakim Road which is a 4/2D road type (4 lanes 2 divided directions) which often experiences traffic jams. Efforts to overcome traffic jams are by implementing a system change from 4/2 to 2/1 (two lanes one way) which is expected to improve traffic performance. Observing this phenomenon, this study intends to determine the effect of implementing a one-way system on traffic performance. The findings in the field show that the application of a one-way system can improve traffic performance with an increase in the level of road service in one lane. The results of multiple regression analysis using vehicle situation, side barriers, and road situations simultaneously have a significant effect on traffic performance with an effect value of 10.3%.

Abstract

Medical waste management in health care facilities is very important because medical waste has various health risks. One hospital can incur up to Rp 1 billion/year for medical waste treatment costs. This study aims to analyze the proper processing of medical waste in hospitals in Jakarta during the pandemic. This type of research is a descriptive observational study conducted cross-sectional through observations on solid waste management at Hospital X, Jakarta City. Decision analysis in this study uses the Analytical Hierarchy Process (AHP) method to support the medical waste treatment decision-making process. In this study, two processing methods are given, namely the incinerator and autoclave. An incinerator is a thermal process used to treat medical waste at controlled temperatures. An autoclave is a medical waste treatment that combines moisture, heat, and pressure to sterilize medical waste. The results of the AHP show that hospitals should optimize autoclaves to sterilize highly infectious waste, which can also be used to sterilize sharp medical waste. Meanwhile, medical waste treatment using incinerators can generate other waste in the form of ash from combustion residues. Ash from the combustion process can contain heavy metals such as Cr, Zn, and Pb. Therefore, a strategy is needed to deal with this waste generation so that the final treatment does not end in a landfill but can be a useful product.

Abstract

Concrete durability is the ability of concrete to last as it was originally planned, in the structure of a building can be defined as the ability to maintain function, stability and aesthetics due to environmental influences so as not to incur large maintenance and repair costs during the planned service life. The durability aspect is very important, especially for infrastructure that has a fairly long service life. Building life is the period or time during which a structure is required to continue to function as planned. In building structures whose construction has been completed, both new and old buildings, specific data related to the quality of the concrete and the planned age of the building is quite difficult to obtain, this is because the influence during the implementation of construction is also not good in governance. documentation, both technical documents and other non-technical documents, therefore it is necessary to have a sufficiently representative tool to test the concrete quality of a building that has been completed to comply with the quality of the built concrete.

Abstract

Changes in land use are closely related to the increasing number of people who are increasing from time to time. This land use change has an impact on increasing the runoff coefficient because the rain that falls will not be retained or seep and flows directly into the river. This is what causes an increase in peak discharge in a watershed. The purpose of this study was to determine the magnitude of changes in peak discharge that occurred in the Serenan watershed in 2015 and 2021 due to changes in land use. The method used in analyzing the peak discharge is the Snyder unit hydrograph, the results of this method will be compared with the measured unit hydrograph to determine the correlation between the two. To make a synthetic unit hydrograph, non-physical parameters are needed in the form of Ct and Cp values. The Ct value used in 2015 was 2.30 and in 2021 it was 2.00 while the Cp value in 2015 was 0.90 and in 2021 it was 1.10. The results of the analysis using the Snyder method showed that the peak discharge was 139.61 m3/s in 2015 and 194.56 m3/s in 2021. The analysis shows that the peak discharge increased by 54.95 m3/s and has a very strong correlation with the hydrograph of the measured unit.

Abstract

The development of urban areas occurs due to the demands for space for activities from the community. Increased activity in the city center has an impact on increasing the need for housing. Kampong Batan is one of the settlements located in the downtown triangle area of Pandanaran road, Pemuda road and Gajah Mada road (PANDAMA). Kampong Batan is also one of the old kampongs that experienced the growth of residential areas due to the development of activities. The implication of the development of activities in the city center to Kampong Batan is experiencing changes that are seen physically and non-physically. In this study, we will examine the characteristics of the Batan settlement in Semarang City in order to find out the changes that occur due to the development of activities in the city center. The research method used is field observation by looking at the development of Kampong Batan from the colonial era to the present based on the map of the previous year of Semarang City. Then it is identified the changes that occur based on the road network, changes in the use of residential space and the characteristics of the settlements. The result is that the settlement of Old Kampong Batan began to be filled with settlements from 1925 to 2000. The changes that are happening today can be seen from the expansion of residential activity space into a terrace, for parking and as a place to sell. In addition, many changes in the area that were previously only areas with residential functions have now turned into trade and service functions.

Abstract

Flexible pavement structures that use asphalt as a binder are currently the mainstay of the Indonesian people because of their large load-bearing capacity and economical construction costs. One type of flexible pavement used is asphalt concrete with the top surface layer or Asphalt Concrete Wearing Course (AC-WC). The use of asphalt from the petroleum refining process is one of the problems because its availability is decreasing. However, the condition of the road pavement which has a limited life requires periodic repairs to maintain the condition of the road. In addition, there are also problems regarding the processing of plastic waste which is still not optimal. Based on data published by the National Waste Management Information System in 2020 as much as 18.3% of the total waste generated. This figure increased by 2.3% from the previous year. Sukoharjo Regency also experienced an increase in sales of plastic waste by 1.16% from 14.04% (in 2019) and now to 15.20% (in 2020). Plastic is one type of polymer in the thermoplastic polymer group which is processed by organic chemical compounds. One type of plastic that is often used is High Density Polyethylene (HDPE) which has strong, light and flexible properties that can soften at a temperature of 130-137"℃" and harden again if. In this study, HDPE plastic bag waste was used as a pure asphalt substitute with variations in the proportion of substitution of 2%, 4%, 6%, 8%, 10%. Where this study aims to analyze the effect of adding HDPE plastic waste as a mixture of AC-WC asphalt on asphalt parameters. From the research conducted, the use of asphalt content of choice is 5.7%. With the results of the mixture with HDPE asphalt mixture HDPE has increased with the addition of variations of HDPE. The flexibility of HDPE asphalt mixture decreased according to the flow meter reading. At a content of 2% HDPE has the largest percentage of VIM, flow, and proportion of VMA, but has the lowest value and percentage of VFB. The best range of HDPE content is in the percentage of 4%-6% because it can increase the value of a more flexible mixture and optimal asphalt absorption. The use of HDPE plastic waste is an alternative in waste treatment and can reduce the use of asphalt. It can be concluded that HDPE plastic bags can be used as an alternative to bitumen substitutes that meet the requirements of Bina Marga 2018 Revised 2nd Edition.

Abstract

Vulnerability is the inability of an individual or community group to minimize the impact caused by a hazard. Information about the level of vulnerability is essential to reduce the risks and effects caused by a disaster. Assessment of the level of vulnerability of threatened areas is carried out to minimise losses and the population exposed to disasters. This study aims to determine the level of vulnerability to coastal abrasion in North Galesong District, Takalar Regency. The analytical method used is the vulnerability index of coastal areas consisting of population components, namely population density and vulnerable groups, economic components, low-income families and anglers, physical components in the form of building density and ecological features in the form of mangrove vegetation. Analysis of vulnerability index data using the vulnerability assessment table issued by the Regulation of the Head of BNPB Number 2 of 2012. The overall results of the research are the vulnerability level of coastal villages in North Galesong District is in the high category. The category of high vulnerability is a condition of a community or society that leads to or causes a high inability to deal with the threat of coastal erosion in the North Galesong District. Vulnerability reduction activities can be carried out by increasing public understanding, especially vulnerable groups and poor fishers groups, through training and socialization activities regarding potential disaster threats, the driving factors for their occurrence and the risks. Socialization of the potential danger of abrasion and extreme waves for fishers is necessary to increase knowledge in dealing with disaster threats. Socialization can be done by inviting anglers to disaster management activities.

Abstract

The average level of vehicle ownership, number of students, working population, number of schools and the average family income can cause an increase in movement in the form of generation and attraction. The rise and pull of traffic on land use, especially in the Districts of Kemang, Parung and Ciseeng is one of the problems that often causes traffic jams during busy times in the morning and afternoon. To overcome these problems, the author opens an analysis of the generation and pull of the movement of traffic flow. The land use that will be analyzed to predict trip generation and attraction, namely the Hospital, Housing, Shopping Center, Office, Industry and Education Areas (SD, SMP and SMA/SMK/Private and Non-Private), while the classification of roads used are Arterial and Collectors located in Parung Subdistrict, Kemang Subdistrict and Ciseeng Subdistrict. Analysis of roads using 2017 MKJI and prediction of generation with ITE (Trip Generation Manual) and modeling with Saturn applications. Looking at the Existing Conditions at the study site for road network data, it can be concluded that the level of service at each entrance in the categories C and D, which means the value of C is a stable current and D is an unstable starting flow. The large number of trip generation and attraction at the study sites in three sub-districts namely Ciseeng, Parung and Kemang Subdistricts which included the education area, trading center or market, parks, and hospitals had a generation of 9,140 trip/hour and a Tug of 29,404 trip/hour. The design equation for transportation modeling in Ciseeng sub-district, Parung dang Kemang is Y = 94,565 + 1,015 (X).
