Era disrupsi meluas sebab adanya pandemi Covid-19 pada pertengahan Maret tahun 2020 secara global termasuk dalam bidang transportasi. Investigasi dilakukan untuk mengidentifikasi karakteritik pengguna transportasi publik antarmoda dan manajemen transportasi antarmoda di Cirebon, Jawa Barat, Indonesia. Desain investigasi menggunakan metode campuran. Sampel dengan teknikk accidental sampling sebanyak 300 responden, dan 6 ahli transportasi di Kota Cirebon. Data dianalisis secara deskriptif dan multicriteria decision melalui AHP. Investigasi memberikan informasi bahwa : (1) Karakteristik responden pengguna transportasi antarmoda ialah berumur 21-30 tahun, berjenis kelamin laki-laki, pendidikan terakhir D3/S1, pekerjaan karyawan swasta, dengan pendapatan kurang dari 1,5 juta perbulan. (2) Alternatif Kebijakan yang seharusnya diambil oleh Pemerintah Kota Cirebon dalam mengatasi persoalan lalulintas di wilayah Cirebon ialah sebagai berikut : (a) Revisi Perda No 8 Tahun 2016, (b) Pengembangan Sistem Transportasi Massal. Kebijakan pengembangan sistem transportasi publik terpadu yang berbentuk bus rapid transit. Kebijakan ini merupakan langkah meretas kemacetan yang dapat mengurangi penggunaan kendaraan pribadi
The main problem of transportation in urban areas is that the growth of private vehicles is not proportional to the increase in the length of the existing roads, so this will make policy makers begin to suppress the use of private vehicles and improve public transportation infrastructure. The use of various modes of transportation so that people can move from one type of transportation to another quickly, cheaply, safely, and comfortably, it requires integrated management of existing stakeholders. The research objective is to analyze the policies of the Cirebon City Government in dealing with transportation problems and traffic jams, (2) to find alternative policies that should be taken by the Cirebon City Government in overcoming traffic problems. Qualitative descriptive method was used for this research. The data collection technique used structured interviews and took as many as 6 respondents from related stakeholders, namely the Department of Traffic and Road Transportation of the Transportation Agency, the Police, Members of the Cirebon City DPRD, BAPPEDA staff, and academics from Swadaya Gunungjati University Cirebon. Data analysis used Analytical Hierarchy Process method. The results of this study conclude that (1) the government is still the actor who has the most role in the transportation management model, then the legislature, and the community. This is evidenced by alternative (1) the continued maintenance of Cirebon City Regional Regulation No. 8 of 2016 concerning the implementation of traffic impact analysis because it is still relevant to the development of transportation infrastructure for the city of Cirebon. (2) It is necessary to take measures to improve the road network by the government as well as to develop an integrated public transportation system in the form of a bus rapid transit. This policy is a step to reduce congestion by reducing the use of private vehicles. (3) The action of the DPRD's supervisory role should be more enhanced than the role of legislation and budgeting, while the community plays an important role in increasing participation in obeying traffic signs
The economic growth in Banyumas Regency, Central Java, and its surroundings, followed by the increasing number of vehicles crossing the area. Among the national roads in Banyumas, the Buntu intersection area is one that requires attention. Data collection was conducted by interviewing and filling out questionnaires directly from respondents. In considering the priority of road repairs, there are 11 criteria used in this study. The alternatives that can be done are asphalt pavement, concrete pavement, and concrete - asphalt pavement. The method used in this study uses the Analytical Hierarchy Process (AHP) method with the help of Expert Choice 11 software. Results of field survey indicated the types of road damage that occurred at the intersection of four dead ends in Banyumas Regency, the Sampang-Buntu section were ruts, potholes, wear (polished aggregate) while for the Buntu section-South Kedu the types of damage include alligator cracking, ruts, potholes, stripping. Concrete pavement repair is the main choice because the Buntu intersection is a national road whose daily traffic is traversed by heavy vehicles with the heaviest axle loads above 10 tons, such as buses or large trucks so that respondents want road pavement repairs at crossroads to prioritize traffic average daily.
Dalam rangka pemerataan taraf hidup dan derajat kesehatan masyarakat di wilayah Ketanggungan Kabupaten Brebes, Pemerintah daerah kota Brebes telah melakukan beberapa upaya strategis, salah satu diantaranya adalah pembangungan infrastruktur RSUD diwilayah tersebut. Projek pembangunan ini bersifat mendesak sehingga perlu diselesaikan tepat waktu agar dapat segera difungsikan. Penjadualan menjadi sangat esensial dalam projek pembangunan tersebut, pekerjaan yang dipercepat dari penjadualan normal tentu saja akan mempengaruhi prmbiayaan proyek. Agar kegiatan pembangunan berjalan dengan efektif, efisien dan optimal, analisa yang tepat sangat diperlukan guna mendukung proses penjadualan kerja sesuai yang diharapkan, termasuk pemilihan item pekerjaan prioritas yang harus segera diselesaikan dalam waktu tertentu dengan pembiayaan yang efisien. Guna menentukan nilai pembiayaan tersebut, penentuan Lintasan Kritis dengan menggunakan PDM (Precedence Diagram Method) sangat diperlukan. Data primer dan sekunder yang digunakan dalam analisis berupa catatan, arsip atau rujukan seperti jurnal penelitian, jadual pelaksanaan, laporan berikut jadual kegiatan proyek, RAB dan rujukan lain yang relevan dengan kegiatan penelitian ini. Hasil analisa dari data diatas diuraikan kedalam diagram jaringan untuk memudahkan penentuan durasi percepatan pelaksanaan melalui penambahan jam kerja sebelum kemudian dihitung optimalisasi biaya yang dihasilkan. Percepatan dilakukan dengan menggunakan metode Crashing, metode Overlapping, dan metode Combine (Crashing dan Overlapping) guna memperoleh hasil percepatan dengan waktu/durasi 7 minggu (21 %) dan juga nilai optimasi biaya pelaksanaan sebesar Rp. 4.207.237.695,03 (7%), dimana biaya pelaksanaan semula adalah Rp. 58.557.390.571,00 menjadi Rp. 54.350.152.875,97.Kata Kunci : optimalisasi, crashing, overlapping, combine ABSTRACTIn order to equalize the standard of living and health status of the community in the area of responsibility of Brebes Regency, the local government of the city of Brebes has made several strategic efforts, one of which is the construction of hospital infrastructure in the region. This development project is urgent so it needs to be completed on time so that it can function immediately. Scheduling is very essential in this development project, work that is accelerated from the normal schedule will of course affect project financing. In order for development activities to run effectively, efficiently and optimally, proper analysis is needed to support the work scheduling process as expected, including the selection of priority work items that must be completed within a certain time with efficient financing. In order to determine the value of the financing, determining the Critical Path using the PDM (Precedence Diagram Method) is very necessary. Primary and secondary data used in the analysis are in the form of notes, archives or references such as research journals, implementation schedules, reports along with project activity schedules, budget plans and other references relevant to this research activity. The results of the analysis of the above data are described in a network diagram to facilitate the determination of the duration of accelerated implementation through the addition of working hours before calculating the resulting cost optimization. Acceleration is carried out using the Crashing method, the Overlapping method, and the Combine method (Crashing and Overlapping) in order to obtain acceleration results with a time/duration of 7 weeks (21%) and also an optimization cost of Rp. 4,207,237,695.03 (7%), where the initial implementation cost was Rp. 58,557,390,571.00 to Rp. 54,350,152,875.97.Keywords: optimization, crashing, overlapping, combine
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
