Nowadays, an airport is no only a place for passengers to come and go, but it plays a significant role in developing and driving the local economy. Realize or not, there will be urban areas that offer connectivity at the airport (aerotropolis), and each airport has different aerotropolis potential. This study aims to analyze changes occurring around Kualanamu International Airport during the pre-construction and post-construction of the airport in 2007 and 2013. Six of the seven criteria of the establishment of aerotropolis show positive results, including air traffic, connectivity, sustainable development, economic income, government support, and Demographics. Significant growth was seen in the added value of the industry, the size of the industrial area, and the increase in GDP per capita. The added value of the industry has an average growth of 99.72% per year from the previous only 1.4% per year, the total area of the industry increased to 780 hectares from the previous only 200 hectares, and the GRDP also more than doubled. The only criterion that has not shown a positive potential is the status of ownership and management by the private sector because until now there has been no partnership in managing Kualanamu International Airport. To realize the development of the concept of aerotropolis in this region, the role of government and stakeholders is needed, both for policies related to aerotopolis development, public-private partnership discourse, the form of partnership, the concession period, and its contribution to the area around the airport.

Sebagai moda transportasi utama antar pulau di Bengkulu, maka dibutuhkan pelayanan dan fasilitas penunjang yang baik, untuk menciptakan keadaan aman dan nyaman bagi pengguna jasa. Penelitian ini bertujuan untuk mengetahui pelayanan dan fasilitas yang diberikan PT ASDP Indonesia Ferry (Persero) Cabang Provinsi Bengkulu berdasarkan kepuasan penumpang. Analisis dilakukan dengan metode Importance and Performance Analysis (IPA) dan Customer Satisfaction Index (CSI), yang kemudian diolah menggunakan aplikasi SPSS 21. Dari metode Importance and Performance Analysis (IPA) didapatkan nilai kepuasan penumpang (X) rata-rata sebesar 45,25 dan nilai harapan (Y) sebesar 54,73. Hal ini menunjukkan bahwa lebih besar harapan dari pada kepuasan penumpang. Artinya, pelayanan perusahaan harus lebih ditingkatkan lagi . Beberapa faktor yang prioritas untuk diperbaiki yaitu kondisi jalan akses ke pelabuhan, lampu penerangan, daya tampung kapal/luas parkir di dalam kapal, ketepatan jadwal keberangkatan, jarak dan ketersediaan angkutan umum dari pelabuhan, serta kesesuaian tarif angkut kendaraan dan barang.  Sedangkan dengan metode Customer Satisfaction Index (CSI), didapatkan nilai sebesar 7,3%. Nilai ini berada pada rentang nilai 0,66-0,80;  yang berarti bahwa konsumen merasa puas secara keseluruhan terhadap pelayanan yang diberikan. Disarankan bahwa perusahaan harus lebih meningkatkan lagi pelayanan untuk memaksimalkan tingkat kepuasan kosumen terhadap perusahaan.

The effectiveness and efficiency of public transport should be a priority for transportation in developing cities. Despite the efforts from the government to improve public transportation, in Jakarta City, Indonesia, there is still 9.93% increase of private vehicles annually per year. In detail, contributor for increasing vehicles in Jakarta is motorcycles with an average annual increase of 10.54% every year, followed by an increase in the percentage of passenger cars by 8.75%. In contrast, the number of public transportation increased only by 1.74%. This research did the evaluation for public transport service in Jakarta by availability and accessibility for them. Neighborhood analysis and Proximity analysis used in this research. The results of the research showed that major problems in public transportations in Jakarta City are the coverage area of the service, route connectivity, and its accessibility for public facilities. There are only 7.78% for coverage area by flexible bus stop service with average walking distance by 300 m. Thus, there are some areas that are not passed by public transport routes, for about 18.5 million people live in blank spot area.

Based data from Bengkulu Environmental centre in 2019, it is known that the volume of waste for Bengkulu city residents per day reaches 373.07 m 3 /day. The amount of water that enters the Air Sebakul TPA causes leachate to collect quickly and then moves to dissolve into the ground. The absence of waste water treatment plant at this landfill causes contamination of surface water and ground water. Especially when it rains, the leachate will flow into the drainage channels of residents around the TPA which causes an unpleasant odor. The purpose of this research ia to determine the ned for WWTP (waste water treatment plant) at the Air Sebakul TPA Bengkulu by using geomembrane layer. The method of the study uses a survey method with forecasting using geometric formulas and mononobe while the data validation test uses a tracking signal approach.The results of this study show that the prediction of the Bengkulu city waste heap and leachate discharge for the next five years is 792.746,35 (m 3 /year) or 9.972 m 3 /day. Based on the current land capacity which has an area of + 30.000 m2, The air Sebakul TPA is declared capable of accommodating waste for the next years. While the planning for the next ten years with waste generation reaching 1.728.810, 26 (m 3 )/year is declared unable to accommodate waste.Therefore, a large-scale land expansion is needed from the existing land availability, as well as a larger IPAL storage capacity.
