Abstract

The population of Bekasi and Depok City continues to increase, so the need for housing will also increase. To fulfill the need for housing, settlements will continue to develop. With the continued development of settlements, the volume of surrounding traffic will also increase. When the increase in traffic volume is not balanced with an increase in the capacity of the road section, there will be long queues of vehicles and long travel times. The purpose of this study is to determine the generation of movements generated from settlements. The results of this study are the estimation of movement generation from Kranggan Permai housing with a linear regression equation model, namely multiple Y1 = -0.007 + 0.011X1 + 0.649X4 + 0.118X5 + 0.336X7 with a generation value of 512.94 and Cibubur housing with a regression equation model, namely Y2 = 0.929 + 0.530X4 + 0.388X6 + 0.423X7 with a generation value of 603.043 smp/hour.

Abstract

Depok Baru Station is a train operating facility that stops regularly to pick up and drop off passengers, Depok Baru Station is in the operational area of DAOP 1 Jakarta. Depok Baru Station has so many passengers that one of the motorized vehicle parking facilities cannot accommodate vehicles parked in the area at Depok Baru Station. Therefore, it is necessary to study parking analysis at Depok Baru Station to provide benefits for motorbike users who do not get parking space, this is to create comfort and security for passengers who park their motorbikes in the Depok Baru Station area. So that it can provide an alternative parking control at Depok Baru Station so that no more motorized vehicles are found that are not parked neatly. This study aims to obtain the existing capacity of parking locations at Depok Baru Station and to obtain parking characteristics (accumulation, duration of each vehicle, parking space turnover rate and parking index) of motorized vehicles in the Depok Baru Station area. This study uses quantitative methods, data collection is carried out by means of observation as primary data, including data on the number of incoming vehicles, data on the number of outgoing vehicles, data representing peak hours, peak days, normal hours, normal days, number of Parking Space Units (SRP) . The results of this study are that the existing parking lot obtained secondary data using the survey method to produce existing data on an area of 840m2 motorcycle parking area with a capacity of 300 SRP (parking space units) and a slope angle of 90° at Depok Baru Station. the largest accumulation stasis was 358 vehicles with an average parking duration of 12.20 hours on Tuesday 13 June 2023. During the eight days of the survey, the maximum parking volume was 480 vehicles with a maximum accumulated vehicle parking of 424 vehicles which occurred on Monday June 12, 2023, the highest turn over for motorcycle parking at Depok Baru Station reached 161.00%, therefore the performance of motorcycle parking is quite high. The capacity of motorcycle parking spaces at Depok Baru Station cannot accommodate the available parking space requirements. This can be reviewed by looking at the parking index which exceeds 100%.

Abstract

The development of urban areas requires a city to meet residential space needs which can have an impact on reducing green open space and causing derivative impacts in the form of decreasing air quality. The problem faced by the City of Yogyakarta in developing green open space is limited land, therefore innovation in green open space development is needed, one of which is developing green infrastructure by implementing a green roof scenario. So this research aims to analyze the application of the green roof scenario to air quality, especially in the distribution of Urban Heat Island (UHI) and Nitrogen Dioxide (NO2) in Yogyakarta City. The method used in this research are Landsat 8 images in 2021 with field observations and delineation of the potential area for green roofs at hotels and malls that have rooftops and the potential to implement green roofs. The research results show that implementing the green roof scenario in Yogyakarta can affect air quality. There are changes in the area that decrease the area in UHI class 4 (>3) from 4.74 Ha to 3.78 Ha and an increase in the Non-UHI area from 1,449.68 Ha to 1,731.57 Ha. Based on the NO2 parameter there has also been a change that increases in the area on a very good air quality scale from 406.80 Ha to 560.96 Ha, and a decrease in the area on a very poor scale from 23.71 Ha to 16.24 Ha. The results of the delineation of the UHI map, NO2 distribution, and spatial plans for Yogyakarta City show that locations with high UHI levels and poor NO2 quality are most widely distributed in Kemantren Gondokusuman, Umbulharjo, and Kotagede.

Abstract

Bekasi Regency is the second highest in the number of motorized vehicles for motorbikes and first for cars. During peak hours at certain sections and intersections, especially in the SGC area, Cikarang Terminal and Jababeka area, there are traffic problems ranging from side obstacles, public transport dropping/picking up passengers incorrectly, and so on. The aim of this research is to outline the performance of existing sections and intersections in the SGC area, Cikarang Terminal and Jababeka area as well as identify existing traffic problems and how to handle them. The methods used are Four step model, section performance analysis, intersection performance analysis, Forecasting, model validation and using PTV Vissim. The research results show that there are 3 problematic road segments with a high level of service, including Jl. Fatahillah 2, Jl. Raya Industri, Jl. Captain Sumantri with a VC Ratio of 0.75, 0.85, and 0.94 respectively and there are 6 of the 9 intersections that have problems, namely the Brigief Dormitory intersection, the terminal intersection, the Yos Sudarso-Kp.Sumantri intersection, the Arief Rahman Hakim- Jl .Industry intersection, Pasir Gombong intersection and SGC intersection. Changes resulting from traffic management and engineering are not very significant every 5 years because many drivers will switch to the road section with the lowest VCR.

Abstract

The country of Indonesia is prone to earthquakes, because geographically Indonesia is located at the meeting point of four tectonic plates, namely the Asian continental plate, the Australian continental plate, the Indian Ocean plate and the pacificocean plate. An earthquake is a vibration or shock that occurs on the surface of the earth due to the sudden release of energy from within, creating seismic waves. Earthquakes are usually caused by movements of the earth's crust (earth plates). Planning an earthquake-resistant building structure in Indonesia is very important, because most areas in Indonesia are in fairly high earthquake areas, so earthquake regulations, namely SNI 1726-2019, have been issued. Design re-planning or follow-up can be done using the real R value. If in the SRPMK structure the real R value is greater than the design R, then the planner can save reinforcement by re-analyzing the structure using real R. With the results of this research analysis, it can be concluded that the SRPMK structure with horizontal irregularities at the Jakarta location, produces a real modified response (R) value (referring to the ATC-40 limit on the ratio of deviations between floors and the rotational capacity of structural components) which is smaller than the specified maximum value. on SNI. In accordance with the provisions of ATC-40, all structural configurations are included in the Damage Control (DO) category level, which means that the transition between Immediate Occupancy (IO) SP-1 and Life Safety (LF) SP-3, the building is still able to withstand the forces of the earthquake that occurred, with the risk of human loss is very small. Only SRPMB's 8-story medium ground structure is included in the Life Safety (LF) category level SP-3. The real R value obtained in the SRPMK structure varies between 7.218 – 8.515. The results of this analysis are not significantly different from existing provisions, and in soft soil conditions the value is smaller than for the SRPMB structure. Real R less than the provisions is the maximum value that can be used based on this research. The real R value obtained in the SRPMB structure varies between 5.081 – 10.276. The results of this analysis are very different from the existing provisions for both soft and medium soil conditions; and Structural optimization has been carried out in each building configuration, but it was found that the cross-sectional dimensions of the SRPMB columns and beams in soft soil conditions were the largest cross-sectional dimensions compared to the others.

Abstract

One of the cities in Indonesia that usually uses motorbike taxis or online motorbike taxi services for transportation is Palembang. Mode selection is the main stage in transportation planning and policy. Urban areas need to provide space for mobility modes and transportation infrastructure because the choice of mode affects how efficiently people can move around. The choice of transport mode is determined by competition between transport modes, which takes into account travel demand and can benefit both private and public transport. Data-based online motorcycle taxi applications facilitate consumer access by making it easier for the general public and students to confirm the driver's identity. Online transportation is becoming increasingly common in big cities like Palembang as the transportation sector develops to better serve people's demand for efficient mobility. This research aims to analyze how travel time and transportation costs can influence the use of online motorcycle taxi transportation in Palembang City. This research uses quantitative descriptive research, this research uses non-probability samples with a purposive approach, namely a technique for determining samples with certain opinions, so the number of samples in this research is 96 people in the city of Palembang who use online motorbike taxi transportation. Data collection techniques using questionnaires, and data analysis using multiple linear regression. Based on the research results, travel time has a significant influence on the use of online motorcycle taxis in Palembang City (0.003 < 0.05), and transportation costs have a significant influence on the use of online motorcycle taxis in Palembang City (0.000 < 0.05). Travel time and transportation costs have a significant influence on the use of online motorcycle taxis in Palembang City (0.000 < 0.05), with a model capability of 70.5%, while the remaining 29.5% of online motorcycle taxi use in Palembang City is influenced by factors others not examined in this study.

Abstract

Construction companies are one of the business sectors that drive the Indonesian economy. The increase in construction companies has led to increased competition in the industry. Culture influences the construction process that applies to the company and the output of construction products. This study aims to find out how organizational culture practices and trends in the large-size construction companies. To investigate the organizational culture practices and trends, the literature study was used to develop a framework and the Competing Values ​​Framework (CVF) through the Organizational Culture Assessment Instrument (OCAI) was adopted. The framework is also extended for each culture type, which are clan, adhocracy, hierarchy, and market into six-key dimensions. The population in this study was 26 large-size construction companies in East Java. The organizational culture practices results found that the dimensions of employee participation, innovation culture, reward, punishment, and teamwork orientation still need to be fully implemented (level 3). Meanwhile, the performance emphasis factor has been fully implemented (level 4). Furthermore, the trend of companies’ culture types is clan culture, where the dominance of cultural types from the strongest to the weakest are clan, market, hierarchy, and adhocracy, with values of 27.51, 26.35, 24.87, and 21.27 respectively. This observation contributes to enriching the study of organizational culture in construction area.

Abstract

Cold Storage Building is a building specifically designed to maintain room temperature in very cold conditions which functions as a commodity preservation area so that it can be stored fresh for a long period of time. When constructing a Cold Storage Building, a very specialist construction process is required. Therefore, it must be carried out using a certain construction method (modular construction), using special Materials (sandwich panels), requiring several specialist subcons & a lack of experienced workers. These conditions make the challenge of building a Cold Storage Building more difficult, which can affect the time performance of the project. This research aims to analyze factors that can influence time performance in the implementation of the Cold Storage Building construction project using the Multiple Linear Regression Analysis method. Based on data analysis, the equation Y = 3.166 + 0.108 X1 + 0.208 X2 + 0.040 X3 + 0.112 X4 + 0.164 Based on the results of the Coefficient of Determination Test, simultaneously Manpower Factors (X1), Material Factors (X2), Machine Factors (X3), Method Factors (X4), Money Factors (X5) and Environment Factors (X6) have an influence contribution of 87.6 % of Time Performance (Y). Meanwhile, for the results of the most dominant factors analysis using Beta Standardized x Zero-Order, it was found that the Material Factors (X2) was the most dominant factors that could influence time performance with an influence value of 34.01%. Considerations in determining alternative solutions to improve time performance on Cold Storage Building construction projects are carried out on the most dominant factors, namely the Material Factors (X2).

Abstract

The implementation of Electronic Catalog Purchasing in the Construction Sector for Reservoir Development carried out by the DKI Jakarta Provincial Water Resources Service is something new in Indonesia and includes the implementation/utilization of the Risk-Based Construction Sector Catalog, so catalog users need to have adequate technical understanding of the field and be able to mitigate risks. Apart from that, the product specifications and prices displayed by Business Actors are not yet final, therefore, at the purchasing stage a "Correction" process is required by the prospective Buyer (in this case the Commitment Making Officer (PPK)/Procurement Official (PP)) and the selection of the appropriate construction service provider. Using e-purchasing methods is influenced by many factors. So to get a service provider who is competent in carrying out construction contracts, it is hoped that the results of selecting a good provider. This makes budget users need what and dominant factors influence the selection of construction service providers using the e-purchasing method. The research method used is the Quantitative Method by processing the research instrument data in the form of a Questionnaire, then data management is carried out using the Statistical Product and Service Solutions (SPSS) Method for the Questionnaire validity test, Questionnaire reliability test, correlation test, Factor Analysis test and RII (Relative Important Index). ). With the results of the sequence of sub-factors that influence service users in determining the selection of a reservoir construction provider using the E-purchasing method via an electronic catalog, namely: RII: 0.967), and Management of the business entity is not under criminal proceedings (RII: 0.963), 0.958), 0.949) and Variable X1 Administrative Qualification Criteria is the dominant factor variable.
