ABSTRACT MANUSCRIPT HISTORY HKBP Church has an important parking lot to facilitate the parking needs of A the congregants who want to worship at the church. The parking lot Ais located around the HKBP Tangerang City Multipurpose Building, which is still A functional, but the parking capacity could not accommodate the number of vehicles needed. Aims: The objective of this article is to review the parking layout design of the HKBP Tangerang City Multipurpose Building in order to optimize the number of parking vehicles. Methodology and results: The 90A parking pattern for 40-motorcycles and the lack of sufficient parking spaces clearly interfere the available area for other facilities, making parking a very important issue. Conclusion, significance and impact study: The study employed the observation method, which was carried out by several field surveyors. The results were considered as 'primary data', while secondary data were obtained from various references and previous studies. This paper demonstrates that effective parking lot management requires an optimal parking pattern and flow. Through simulation, it was determined that a 45A angle parking pattern can accommodate 200 motorcycles, while a 90A angle pattern can accommodate 100 cars.

Number 1, pp 36 Ae 46, 2025 INTRODUCTION Parking is a temporary situation in which a vehicle is left by its driver . It is generally permissible to park on the side of the road, but parking in the middle of the highway . is legally prohibited. The definition of parking encompasses any vehicle that is stationary at a specific location, irrespective of whether a traffic sign designates the location. This includes both the loading and unloading of goods or people. Parking is a significant component of the transportation network system. consequently, its regulation influences network performance . The configuration of the building layout is paramount, with the arrangement of parking spaces for two-wheeled and four-wheeled vehicles exerting a significant influence . It is anticipated that they will be connected following the function and purpose of the building infrastructure, thus ensuring a safe, smooth, and efficient means of transportation devoid of technical, environmental, and architectural barriers. The HKBP Tangerang Kota Church is a place of Christian worship located in the middle of a residential neighborhood . ee Figure 1. Its address is Gg. Melati II No. RT. 001/RW. Tanah Tinggi. Cipondoh sub-district. Tangerang City. Banten 15148 . The edifice is situated between residential properties . ee Figure 1. The yellow boxes denote the location of the multifunctional building and the The primary church edifice, which is frequently utilized for various activities, is in the orange box on the right. Figure 1. Location of HKBP Tangerang City Multipurpose Building (Google Earth, 2. The relationship between residential density and population, on the one hand, and the number of church congregations, on the other, is an essential consideration in optimizing parking capacity. A strategic approach to parking arrangement patterns in the affected area is essential when a deficiency in parking capacity is identified. Currently, the HKBP Tangerang City Doi: https://doi. org/10. 25105/livas. Design of Parking the Lot Layout of HKBP Multi-Purpose Building in Tangerang City Zulyadaen. Manurung p-ISSN 2580-7552. e-ISSN 2548-7515. Volume 10. Number 1, pp 36 Ae 46, 2025 Multipurpose Building has two parking lots. one is to the left of the Church, and the other is in the field. The field lot can accommodate 68 cars and 93 motorcycles, while the lot to the left of the Church can accommodate 40 motorcycles. The resource person has stated that the current condition of the parking area is suboptimal and that improvements are required to ensure full utilization of the parking area, thereby preventing vehicles from parking on the road. In light of these observations, a study on the Parking Planning of HKBP Tangerang City Multipurpose Building is recommended. Preceding studies have demonstrated that the layout of facilities is paramount to enhancing operational success and efficiency. Facility layouts are devised using the Activity Relationship Chart (ARC) and the Total Closeness Rating (TCR). ARC analysis facilitates identifying relationships between facilities, such as parking lots. The TCR analysis determines the priorities of the facility while developing the proposed layout . The author employed the AutoCAD 2021 application in this study to calculate and plan the proposed layout drawings. It is hoped that this proposed layout will assist the church management in re-arranging the parking area so that the capacity of the HKBP Tangerang City Church parking area is optimized. RESEARCH METHOD The research method is the sequence of steps that must be determined before resolving problems . The objective is to facilitate the execution of the research and to streamline the analysis of prevailing issues . The following are the research methods that guided this study. Preliminary study The preliminary study comprised a field review and consultation with relevant parties regarding the issues encountered and the subsequent development phase requirements. This preliminary research was conducted through two methods: field and literature studies. ProblemAos identification At this stage, the researcher identifies the problems of regularity/irregularity of parking patterns, land availability, parking capacity, patterns, types of vehicles, and time of use of parking areas. Data collection Direct field observation is one way to collect primary data. Primary data is from direct observation at the study site, where some people are involved as surveyors to help observe and record the necessary data . Primary data in this study are the number of vehicles. Doi: https://doi. org/10. 25105/livas. Design of Parking the Lot Layout of HKBP Multi-Purpose Building in Tangerang City Zulyadaen.

The data collection method uses pen and pencil equipment, roll meters, and pipe meters. Survey personnel consisted of several people placed at three observation points. The survey was conducted three days from 00 to 15. 00 West Indonesia Time. Analysis The type, number, and time of parking vehicles determine the parking area and capacity on the existing site. Time management is a consideration in deciding how much capacity can be accommodated in one day, and parking layout patterns affect how efficient parking lots are to get the optimal number of parking vehicles. RESULTS AND DISCUSSION Direct observation and interviews with relevant parties, such as parking attendants, were used to identify the current parking system. The results are as follows: The area of the church side parking lot is approximately 540 m2, and the building area of HKBP Tangerang City Multipurpose Building is 11080 m2. There are two entrances and exits for motorcycles and cars. In addition to the four-wheeled vehicles parked on the field, there is a unique motorcycle parking lot. Strict guarding of parking spaces aims to avoid the loss of motorcycles and cars. Unused parking spaces were found due to the irregular placement of vehicles when Lack of information about the occupancy of parking spaces causes some motorists to park their vehicles out of place when conditions are full.

Number 1, pp 36 Ae 46, 2025 Figure 2. Parking pattern at the HKBP Multipurpose Building in Tangerang City (Zulyadaen, 2. There are currently two parking lots at HKBP Tangerang City Multipurpose Building, namely, next to the church and in the field. All parking lots use 90A and 45A angle patterns. The capacity of the parking lot next to the church is 40 motorcycles. As mentioned above, the parking lots in these two locations are inefficiently used. The researcher tried to collect data and information to process them and reorganize the parking lot so that the congregation can use it as optimally as possible when they worship there. Figure 3. The existing layout of the parking lot of the HKBP multipurpose building in Tangerang City. (Zulyadaen, 2. Above is a picture of the parking lot layout of the multipurpose building and its current size, where the main obstacle is that the parking lot in the field can only accommodate 68 cars and 93 motorcycles. The parking lot to the left of the church can accommodate 70 Every day, it feels inadequate. So, there are four models for parking motorcycles: 30o, 45A, 60A, and 90A. After measuring four times, the motorcycles should have a width of 72 cm, a length of 185 cm per motorcycle, and a distance of 35 cm between each number. With the above plan, the researcher tried to rearrange the layout so that the inadequate parking lot could accommodate the motorcycles and cars parked by calculating the four existing parking patterns and determining which one was more effective.

Number 1, pp 36 Ae 46, 2025 Maximum Capacity of Parking Area The calculation of the maximum capacity of the car park site is based on two factors: the land area allocated for vehicle parking and the number of parking spaces. The formula used to calculate the capacity of 90A angled parking spaces . T h e f ormula for calculating the capacity of 30A angled parking spaces. The formula for calculating the capacity of 45A angled parking spaces . The formula for calculating the capacity of 60A angled parking spaces . Figure 4. Parking pattern with 45A angle. ( Zulyadaen, 2. The number of 813 motorbike vehicles is still divided by 4. 05, where the number is calculated by dividing the total number of all alleys by the free space, 17,45 = 4,05 then 810 = 200 motorbike vehicles. 4,05 Parking Time Parking time is defined as the amount of time one vehicle spends in a parking area. The calculation of vehicle parking time considers vehicles entering and exiting on worship days and weekdays during the survey period . Doi: https://doi. org/10. 25105/livas.

Average data of vehicles parked in the HKBP Multipurpose Building in Tangerang City. Day Number of parked vehicles yu=5 Average The data processing results show that parking arrangements must be made to reduce the amount of unused land. This can be seen from the flow of parking and its patterns . After calculating with two existing patterns, the result is that the parking lot area next to the church has an area of approximately 540 m2 and 11080 m2 building area of HKBP Tangerang City Multipurpose Building, then the result is: 45A parking pattern can accommodate up to 200 motorcycle vehicles. 90A parking pattern for 100 four-wheelers, and 90A parking pattern for 40 motorcycles only. Criteria for Determining the Parking Layout There are several criteria for determining the layout of a car park . Car parks should be located on a level surface. A cut-and-fill system should be considered if the original land surface is sloping. The purpose of providing a level surface in the car park is to ensure the safety of the vehicles so that they can be parked safely and do not roll. If the distance between the car park and the place of worship is large enough, it is necessary to have clear and direct access to the car park. In terms of its use, the car park is divided into : A Parking of four-wheeled vehicles, cars, and sedans, a maximum of 100 vehicles. A Parking two-wheeled vehicles, bicycles, and motorcycles, a maximum of 150 to 200 From the point of view of their design, the criteria and principles for car parks should be broadly in line with the following factors.

A Availability of parking support facilities. Selected Concept Drawings Based on consideration of lessons learned from other cases . , the following criteria were developed for the layout of the existing parking lot layout : The parking layout for cars and motorcycles is separated Factors influencing parking layout differences between cars and motorcycles are vehicle size, safety, and accessibility. In this case, the size of the car is more significant than that of the motorcycle. Therefore, car parking areas require more space for maneuvering and safe parking. In addition, the motorcycle parking is closer to the guard post, making it easier to monitor and more compact to be placed in a smaller space. Car parking pattern with a 90A angle In general, the vehicle position is 90A. In terms of space effectiveness, the 90A angle is most favorable. This parking pattern has more capacity when compared to parallel parking patterns, but for the ease and comfort of drivers, maneuvering in and out of parking spaces is more complex than parking patterns with angles smaller than 90A. This parking pattern with an angle of 90A has a capacity of 4 . wheeled vehicles, as many The 45A angle parking pattern has been shown to offer several advantages over other parking patterns, including a greater capacity for vehicles and easier maneuvering. Compared to the parallel parking pattern, the 45A angle parking pattern has been demonstrated to have a larger capacity and can accommodate more motorcycles in the same area. Furthermore, drivers have been shown to find it easier to maneuver in and out of parking spaces with a 45A angle, enhancing both comfort and convenience for The author's proposal for a motorcycle parking pattern with a 45A angle is intended to optimize capacity and comfort, with the capacity to accommodate up to 200 twowheeled vehicles. In the HKBP Tangerang City Multipurpose Building field, the existing parking pattern previously accommodated 68 cars and 93 motorbikes. In contrast, the parking lot to the left of the church can accommodate 40 motorbikes. The current Doi: https://doi. org/10. 25105/livas.

CONCLUSION The parking issue is of significant concern, as the scarcity of parking spaces can impede the available space for other facilities. A practical parking layout, characterized by a welldesigned pattern and efficient flow, can optimize space utilization. A 45A angle parking configuration can accommodate 200 motorbikes, while a 90A angle pattern can accommodate 100 cars. Furthermore, a 90A parking layout can accommodate 40 REFERENCES
