Abstract

Banyuwangi Regency, located in East Java, Indonesia, has rapidly emerged as a leading tourism destination due to its exceptional natural beauty and cultural richness. The increasing number of domestic and international tourist visits requires adequate transport infrastructure to ensure accessibility and connectivity across major destinations. Without a well-functioning transport system, the tourism sector may face barriers to sustainable growth and equitable regional development. Accessibility is defined as the ease with which tourists can reach specific destinations, whereas connectivity reflects the degree of linkage and travel efficiency between those destinations. This study seeks to analyze the performance of the tourism transport system in Banyuwangi by applying the Hansen accessibility model, using both to assess spatial accessibility and inter-destination connectivity. Primary data were collected by measuring the distances between selected tourist destinations (ODTWs) along existing transport routes through Google Maps. Secondary data were obtained from the Banyuwangi Regency Tourism Office, including records of tourist arrival volumes. The results show that accessibility values range from 0.0067 to 0.07, while connectivity values vary between 0.87 and 1.09. These findings reveal significant disparities in transport service distribution and functional integration between routes. The study emphasizes the urgent need for strategic planning and investment in transport systems tailored to the dynamics of tourism flows. Enhancing transport accessibility and connectivity is essential not only to support tourist mobility but also to promote inclusive and sustainable tourism development across the region.

Abstract

Owner Estimate (OE) determination in Engineering, Procurement, and Construction (EPC) projects remains a challenging process due to high levels of uncertainty arising from technical complexity, market fluctuations, incomplete information, and project-specific risks. Although Monte Carlo Simulation (MCS) can generate probabilistic cost estimates through percentile distributions, it does not provide a systematic mechanism for selecting the most appropriate percentile as the final OE. This study aims to develop a risk-based decision framework that integrates probabilistic estimation and multi-criteria decision-making approaches to support a transparent and objective OE percentile selection process. The research applied a combination of Monte Carlo Simulation to generate percentile-based alternatives, the Delphi method to identify and weight relevant decision criteria based on expert consensus, and PROMETHEE II to rank alternative OE percentiles. The results demonstrate that the proposed framework effectively transforms probabilistic outputs into structured decision alternatives by considering technical, economic, and organizational factors. Among the evaluated alternatives, P80 achieved the highest PROMETHEE II net flow value (? = 0.508), indicating its superior balance between risk mitigation and cost efficiency. The findings confirm that OE selection should not rely solely on statistical confidence levels or managerial judgment but requires an integrated analytical approach. This study concludes that the proposed framework provides a transparent, reproducible, and risk-based decision model to improve consistency and reliability in EPC project cost estimation.

Abstract

ABSTRACTBekasi City is a buffer city of the Capital City of DKI Jakarta, with a population of 2,873,484 inhabitant. KRL, LRT, and BRT were built to meet the needs of trips to the city of Jakarta to reduce congestion. In fact, many people didn’t use KRL, LRT, and BRT as means to go to Jakarta. Therefore it is necessary to anlyze the accessibility to the three stations. The method used in this study is the Accessibility Method with the Competition Measure. Each land use surrounded the Bus Rapid Transit station area, Jabodebek LRT station, and Commuter Train Station is identified. Each facility's capacity, the physical distance between zones, travel time based on mode, and travel costs are the considered variables. The results show that the worst accessibility value is on Thursday, with the worst accessibility value of 5.804 for centroid number 235. The total area with a good accessibility category is 89 km2, moderate is 117 km2, and bad is 89 Km2. From the multiple regression analysis, the modeling form Y = -0.731 + 0.006 X1 + 0.075 X2 + 0.03 X3 + 0.031 X4 is obtained. From the new accessibility results, the value obtained the results of the category of good accessibility from 89 Km2 become 86 km2, areas with moderate accessibility category increased from 117 Km2 to 132 km2, and areas with poor accessibility categories from 33 km2 to 19 km2.Keywords: Accessibility; BRT Station; LRT Station; KRL Station; Public Transportation.ABSTRAKKota Bekasi merupakan kota penyangga Ibukota DKI Jakarta dengan jumlah penduduk 2.873.484 jiwa, serta memiliki potensi pergerakan orang yang besar menuju wilayah DKI Jakarta. KRL, LRT, dan BRT di Kota Bekasi dibangun untuk memenuhi kebutuhan perjalanan menuju Kota Jakarta untuk mengurangi kemacetan. Pada kenyataannya, banyak orang tidak menggunakan sarana tersebut menuju ke Kota Jakarta. Oleh karena itu perlu dilakukan penelitian untuk mengetahui tingkat pelayanan angkutan umum menuju ketiga stasiun tersebut. Salah satu indikator tingkat pelayanan adalah aksesibilitas. Adapun metode yang digunakan didalam penelitian ini adalah pengukuran aksesibilitas dengan metode penghitungan Competition Measure, dimana pada masing masing kawasan stasiun Bus Rapid Transit, stasiun LRT Jabodebek, Stasiun Kereta Commuter akan dilakukan penghitungan kapasitas masing–masing fasilitas, jarak fisik antar zona,  waktu tempuh perjalanan, biaya perjalanan. Penghitungan menghasilkan nilai aksesibilitas terburuk pada hari kamis dengan nilai aksesibilitas terburuk 5.804 pada centroid nomor 235, dengan luas wilayah kategori baik sebesar 89 Km2, sedang sebesar 117 Km2, dan buruk sebesar 89 Km2. Dari analisa regresi berganda didapatkan bentuk pemodelan Y  = -0.731 + 0.006 X1 + 0.075 X2 + 0.03 X3 + 0.031 X4. Dari hasil nilai aksesibilitas baru didapatkan hasil kategori aksesibilitas baik sebesar 89 Km2 menjadi 86 Km2, wilayah dengan kategori aksesibilitas sedang dari 117 Km2 menjadi 132 Km2, dan wilayah dengan kategori aksesibilitas buruk dari 33 Km2 menjadi 19 Km2.Kata Kunci: Aksesibilitas; Stasiun BRT; Stasiun LRT; Stasiun KRL; Pengangkutan Umum.

Abstract

Analysis of Airport Passangers Trip Origin Towards The Access To The Airport (Case Study: Semarang, Yogyakarta and Surabaya): The economic development of a city will be accompanied by an increase in the number of population, which means it will generate more mobility as well as the need of transportation. Changes in travel time due to congestion will also affect travel cost. From the relationship between the growth of the number of vehicles in a city and the accessibility to the airport, it is necessary to research the significance of that relationship. Three airports namely Ahmad Yani Airport, Adisucipto Airport and Juanda Airport with the correspondent cities they served used as the case study. The data of travel time and travel distance of the respondents processed using the relation analysis. The problem solving method exercised the distribution of modal choice, the difference of travel time to theairport and to forecast the number of passengers if mass transport is utilized. The result of the study indicates that the growth of air transport demand correlate positively with the population growth. Respondents indicates mass rail transport is required if the possibility of loss of flight can occur in cities with varying fluctuations in travel time. Berkembangnya ekonomi kota akan diiringi dengan bertambahnya jumlah penduduk dan meningkatkan tingkat bermobilitas yang menyebabkan kebutuhan transportasi bertambah. Perubahan waktu perjalanan juga akan mempengaruhi biaya perjalanan yang diakibatkan kemacetan. Dari hubungan antara pertumbuhan jumlah kendaraan disuatu kota dan aksesibilitas menuju bandara, maka perlu dilakukan penelitian signifikansi hubungan tersebut. Sebagai studi kasus digunakan data 3 bandara yaitu Bandara Ahmad Yani, Bandara Adisucipto dan Bandara Juanda. Data waktu tempuh dan jarak perjalanan responden diolah dalam analisis hubungan waktu tempuh dan jarak perjalanan. Metode penyelesaian permasalahan yang ada adalah mengidentifikasi distribusi penggunaan moda, menghitung perbedaan waktu tempuh perjalanan menuju bandara dan dilakukan peramalan jumlah penumpang apabila diadakan transportasi massal. Hasil Penelitian menunjukkan adanya kesesuaian bahwa pertumbuhan demand transportasi udara seiring dengan pertumbuhan jumlah penduduk. Responden menunjukkan transportasi massal rel dibutuhkan jika kemungkinan terjadinya kehilangan penerbangan dapat terjadi pada kota dengan fluktuasi perubahan waktu tempuh yang sangat bervariasi.

Abstract

Kebutuhan transportasi udara terus meningkat dari tahun ke tahun. Peningkatan kebutuhan ini juga berdampak pada lingkungan sekitar bandar udara dan salah satunya adalah dampak kebisingan dari operasional pesawat. Dalam penelitian ini, akan dibandingkan kapasitas runway dengan sudut approach standar (3⁰) dengan steep approach (4,5⁰). Dengan data lalu lintas dari peak hour eksisting, akan diketahui kapasitas runway awal menggunakan diagram ruang-waktu yang menghasilkan kapasitas ultimate dari runway tersebut dan dapat diketahui pula kapasitas runway steep approach. Dengan kapasitas runway ultimate dan kapasitas runway steep approach, akan diketahui perbedaan kapasitas dari kedua metode approach dan diketahui pengurangan kapasitas dari steep approach. Hasil analisa menggunakan diagram ruang waktu menunjukkan bahwa tidak terjadi pengurangan kapasitas dengan 34 pergerakan per jam. Jenis pesawat yang memenuhi target kecepatan 137±4kt adalah Airbus A320. Kesimpulan dari penelitian ini adalah steep approach tidak mengurangi kapasitas runway pada peak hour. Pada peak hour, pesawat cenderung homogen dalam tipe wake turbulence yang dihasilkan. Penggunaan ILS akan diperuntukkan bagi standard approach dan steep approach dapat menggunakan Microwave Landing System atau GBAS (Ground Based Augmentation System) Landing System. Terjadi pengurangan kebisingan tingkat 2 dari 1400 m menjadi 1282 m dan pada area perumahan sekitar bandara sebesar 60,5%.
