This study aims to measure the values of passenger car unit (PCU) at a four-legged roundabout based on the time occupancy data in complex traffic operation. Within mixed traffic, the PCUs are needed as a equivalency factor to convert various type of vehicles to a standard unit. The unit of PCU was used to determine capacity and level of service of specific the traffic condition. The composition of vehicles going through the intersection, mostly varies and each type of vehicles tends to have diverse effects on capacity and level of services. Consequently, a conversion factor from various vehicles to a standard vehicle is required. The data of this study was collected using a drone at the investigated roundabout at one of the major roundabouts in Aceh Besar, Aceh province, Indonesia. The method used was the vehicle's time occupancy, in which calculated from the average time required by each vehicle to pass through the roundabout area. The results show that the PCU values obtained is 0.16 for motorcycle, 0.59 for rickshaw, 1.07 for pickup, 1.91 for a medium vehicle, and 3.76 for the heavy vehicle. These results should be utilized for converting various type of vehicles into PCUs to estimate capacity and level of services, especially at the roundabout trafict. This results may be suitable to revise the Indonesian Traffic Code, named Indonesian Highway Capacity Manual 1997, and useful for ongoing national-level efforts to upgrade the Indonesian Highway Capacity Manual.
Kapasitas jalinan sangat berperan penting untuk perencanaan bundaran lalu lintas terutama pada lalu lintas campuran dengan komposisi lalu lintas didominasi kendaraan roda dua (sepeda motor). Simpang Tujuh Ulee Kareng merupakan simpang tak bersinyal dengan kondisi lalu lintas campuran dengan proporsi roda dua sangat tinggi. Maka, penelitian ini bertujuan untuk meninjau pengaruh proporsi roda dua terhadap kapasitas bagian jalinan. Metode analisis digunakan simulasi lalu lintas dengan menggunakan simulator VISSIM 6.00-22. Lokasi penelitian dipilih Simpang Tujuh Ulee Kareng dimana berdasarkan Rencana Tata Bangunan dan Lingkungan (RTBL) Kawasan Simpang Tujuh Ulee Kareng yang direncanakan oleh pemerintah Kota Banda Aceh dengan konstruksi Bundaran. Hasil penelitian dengan menggunakan simulator lalu lintas VISSIM 6.00-22 kapasitas bagian jalinan hanya mengalami perubahan kecil pada skenario komposisi roda dua 40% - 90%. Penurunan kapasitas bagian jalinan terjadi saat komposisi roda dua/motorcycle (MC) pada skenario 10% - 30% yang diakibatkan meningkatnya komposisi kendaraan ringan/light vehicle (LV) sehingga membuat banyaknya ruang antara (gap) kendaraan yang kosong. Panjang antrian dan tundaan yang terjadi semakin rendah saat komposisi roda dua (MC) pada skenario 40% - 90%. Dari hasil simulasi dapat dilihat bahwa roda dua (MC) memberikan keleluasaan pada ruang jalan sehingga arus menjadi lebih lancar. Seiring meningkatnya komposisi kendaraan ringan (LV) atau roda empat mengakibatkan ruang jalan menjadi lebih sempit. Kendaraan yang berada di jalinan cukup sulit untuk bergerak sehingga kecepatan menurun yang berdampak pada antrian kendaraan yang panjang dan menyebabkan menurunnya kapasitas bagian jalinan Bundaran.
AKDP movement has been declining lately based on an interview survey conducted on AKDP operators that it can be seen that the number of people using L-300 cars is on average above 5 passengers and the average does not meet the available passenger seats of 11 to 16 seats . The current condition shows that people tend to use private transportation / cars compared to public transportation. Judging from the condition of the AKPD in Aceh today many people use private vehicles to make movements. The purpose of this study was to determine the performance of AKDP transport in Aceh Province using the load factor approach. The method used is the Directorate General of Land Transportation method in 2002 and refers to the Decree of Dirjendat No. 274, 1996. Data collection was carried out by means of a static survey using the interview method. From the calculation results it can be seen that the load factor of the regular operating AKDP is 64.55%. This reflects that the level of service is still in good condition ie on regular routes totaling 44 routes, while the total number of routes is 321 which operates irregularly. By not operating 277 routes on a regular basis it can be seen that people tend to use private vehicles when traveling. Keywords: AKDP; Public Transport Performance; Minibus; Load Factor __________________________ Abstrak Pergerakan AKDP Akhir-akhir ini semakin menurun berdasarkan survei wawancara yang telah dilakukan terhadap operator AKDP bahwa dapat diketahui jumlah yang menggunakan mobil L-300 rata-rata di atas 5 penumpang dan rata-rata tidak memenuhi kursi penumpang yang tersedia yaitu 11 sampai dengan 16 seat. Kondisi saat ini, menunjukkan masyarakat cenderung menggunakan angkutan pribadi/ mobil dibandingkan dengan angkutan umum. Dilihat dari kondisi AKPD di Aceh saat ini banyak masyarakat menggunakan kendaraan pribadi dalam melakukan pergerakan. Tujuan penelitian ini adalah ingin mengetahui kinerja angkutan AKDP di Provinsi Aceh dengan pendekatan load factor. Metode yang digunakan adalah metode Ditjen Perhubungan Darat tahun 2002 dan mengacu pada SK Dirjendat No. 274, 1996. Pengambilan data dilakukan dengan cara survei statis dengan metode wawancara. Dari hasil perhitungan dapat diketahui nilai load factor AKDP yang beroperasi reguler adalah 64,55 %. Ini mencerminkan bahwa tingkat pelayanan masih dalam keadaan baik, yaitu pada trayek reguler yang berjumlah 44 trayek, sedangkan jumlah trayek seluruhnya adalah 321 yang beroperasi tidak reguler. Dengan tidak beroperasinya 277 trayek secara reguler dapat diketahui bahwa masyarakat cenderung menggunakan kendaraan pribadi dalam berpergian.

The presence of sidewalks is very important to support the safety, comfortability, and activities of pedestrians in CBD (Central Business District). Therefore, this study was conducted to analyze the service quality of the pedestrian lanes in two CBDs of Banda Aceh City using the Importance-Performance Analysis (IPA) method. The results showed most of the service quality variables of the sidewalks are in quadrant A (concentrate here), followed by C (low priority), D (possible over-skill), and B (keep up the good work). This means the qualities of the sidewalk services need to be improved to ensure their performances are in line with pedestrians' expectations. This is necessary because most of the width and height of these sidewalks were found through field investigation not to meet government standards, whereas several obstacles were also discovered such as the presence of traders, merchandises, and parked vehicles, as well as the lack of seating facilities and disability lanes. These violations are part of the problems in many cities of Indonesia and other developing countries and are due to the lack of public awareness and supervision by the authorities. Therefore, further improvement is recommended to realize the expected pedestrian path.
Public transportation is widely considered more attractive in developed countries compared to developing countries, primarily due to its level of service performance, and the influencing factors vary depending on the characteristics of the place and the community. Meanwhile, passenger loyalty is essential to increase the demand for public transportation. This research aims to investigate the impact of service performance and passenger satisfaction on passenger loyalty to public bus transportation in Banda Aceh, Indonesia. The research was conducted on six Trans Koetaradja Bus corridors that connect the city and its surrounding areas, and the data was analyzed using the multiple regression method with SPSS. The results showed that that service performance and passenger satisfaction had an impact on passenger loyalty, with a correlation coefficient of 0.563. However, the determination value (R2) was only 0.317, indicating that only 31.7% of the service performance and passenger satisfaction affected passenger loyalty to the Trans Koetaradja bus. The remaining 68.3% were influenced by other variables. Meanwhile, the low contribution of service performance and passenger satisfaction was likely due to the fact that Trans Koetaradja passengers have private vehicles, which are considered more efficient. This can be seen from the respondents' trip frequency of only 1-2 times a week. To address this issue, integrated and accessible public transportation and mixed-use urban planning are needed in Banda Aceh to improve travel duration. It is hoped that these results can improve the public interest and loyalty to public transportation in their daily activities.
