This paper investigated how much the public's willingness to pay (WTP) for the cost of public water supply services (PDAM) in Pekanbaru City. This research also projected how much urban water demand of this city for period of 2014-2032. This study divided samples into two categories, namely (i) middle and high income society, and (ii) low income one. These categories were based on the type of house ownership, and the percentage of low income family in this city This research obtained two main factors affected to the WTP for public water services (Y), such as; (i) the number of family members (X1), and (ii) the amount of family income (X2). The equation formula of Y = -677.816 + 12934.502 X1 + 0.012 X2. The average public’s willingness to connect to PDAM for the middle and high income society was 62.13% and for the lower class was 44.44%.There was a trend that the middle and high incomes society’s water demand was relatively higher than that the lower one. The amount of water tariffs for middle and high income class society was at the average of Rp.6.615 / m3, and Rp.4.971/m3 for the lower income one. This tariff was higher than the average tariff in 2014 (Rp. 3,300 / m3). The water supply capacity in 2014 was estimated to 620 l/sec, and it was projected that water demand in 2032 will increase to 3,946 l/sec (three folds).

[EN] It was acknowledged that, the Hang Nadim International Airport’s aircraft movements increased significantly at recent 10 years period. The shift in aircraft dimensions and weights have raised questions whether or not the existing apron pavement dimensions are sufficient for accommodating the increase aircraft parking demands and to bear aircraft load changes. The purpose of this research is to evaluate and analyze the apron dimensions and pavement thickness at Hang Nadim Airport. This research was used two relevant methods as guidelines for calculating this apron dimension and thickness; ICAO (International Civil Aviation Organization) Anex 14 2013 and FAA (Federal Aviation Administration) 150/5320-6d. It was calculated that the apron dimension need to be expanded to 1600 m x 150 m for accommodating 31 aircraft parking in 2025 (11 units B747- 300 + 16 units B737-900 + 4 units F27). The apron thickness would be 46.2 cm of base course and 10 cm of subbase course.

Kerapatan stasiun hujan eksisting dikaji berdasarkan metode standar World Meteorogical Organization sedangkan analisis rasionalisasi jumlah dan sebaran stasiun hujan berdasarkan data hujan harian dan variasi tingkat kesalahan menggunakan Metode Kagan-Rodda. Metode Kagan-Rodda telah digunakan di beberapa wilayah penelitian dengan beragam kategori fisiografi dan lingkup terbatas pada daerah aliran sungai. Sehingga dirasa perlu melakukan pengembangan cakupan penelitian untuk wilayah yang lebih luas yaitu Wilayah Sungai. Lokasi penelitian adalah Wilayah Sungai Rokan dengan fisiografi dataran tropis mediteran dan sedang seluas 22.455,28 km². Stasiun hujan eksisting berjumlah 13 stasiun hujan dan 1 stasiun tidak lolos Uji F, koefisien luasan Thiessen eksisting tidak merata sebesar 165,03 km2-3.758,12 km2 (0,007-0,17), dan korelasi hujan harian sebesar 0,03-0,37. Evaluasi analisis WMO menghasilkan 7 stasiun hujan yang memenuhi standar untuk luas daerah pengaruh sebesar 1.000–2.500 km2/stasiun. Perhitungan metode Kagan-Rodda dilakukan 2 skenario kesalahan perataan, skenario I dengan kesalahan perataan (Z1) sebesar 4,93% menghasilkan 37 stasiun hujan, luasan pengaruh Thiessen 273,89 km2–1197,80 km2 (0,01-0,05), nilai r(0) sebesar 0,20, jarak antar stasiun hujan sejauh 26,36 km, dan 2 stasiun memenuhi standar WMO. Sedangkan skenario II dengan Z1 sebesar 9,72% menghasilkan 10 stasiun hujan, dimana mempertahankan 2 stasiun, memindahkan 8 stasiun dan menutup 3 stasiun diperoleh luasan pengaruh Thiessen 1.691,71 km2–2.488,21 km2 (0,08-0,11), jarak antar stasiun hujan sejauh 50,70 km, dan seluruh stasiun memenuhi standar WMO. Rasionalisasi metode Kagan-Rodda skenario II relatif mewakili luas pengaruh wilayah dibandingkan skenario I. [EN] The distribution of locations and the number of ideal rain stations will represent rain events to support the accuracy of analytical information in an area. The density of existing rain stations was assessed based on the standard method of the World Meteorological Organization, while the rationalization analysis of the number and distribution of rain stations based on daily rainfall data and variations in error rates used the Kagan-Rodda method. The Kagan-Rodda method has been used in several research areas with various physiographic categories and limited scope in watersheds. So it is necessary to develop the scope of research for a wider area, namely the River Basin. The research location is the Rokan River Basin with physiography of the Mediterranean and medium tropical plains covering an area of 22,455.28 km². The existing rain stations are 13 rain stations and 1 station does not pass the F test, the coefficient of the existing Thiessen area is uneven at 165.03 km2-3,758.12 km2 (0.007-0.17), and the daily rainfall correlation is 0.03-0, 37. WMO analysis evaluation resulted in 7 rain stations that met the standard for the area of influence of 1,000–2,500 km2/station. The calculation of the Kagan-Rodda method is carried out in 2 scenarios of smoothing error, scenario I with an alignment error (Z1) of 4.93% resulting in 37 rain stations, the area of influence of Thiessen is 273.89 km2–1197.80 km2 (0.01-0.05) , the value of r(0) is 0.20, the distance between rain stations is 26.36 km, and 2 stations meet the WMO standard. While scenario II with Z1 of 9.72% produces 10 rain stations, which maintains 2 stations, moves 8 stations and closes 3 stations, the Thiessen influence area is 1,691.71 km2–2,488.21 km2 (0.08-0.11), the distance between rain stations is 50.70 km, and all stations meet WMO standards. The rationalization of the Kagan-Rodda method in scenario II is relatively representative of the area of influence compared to scenario I.

Sultan Mahmud badaruddin II International Airport is located in Palembang City, South Sumatra Province. The development of air freight movements at the airport indicates that passenger terminal facilities that have an existing area of 34,000 m2 with a capacity of 3.4 million per year can no longer accommodate the existing passenger volume. This can be seen from the increase in the total number of passengers each year which exceeds capacity to reach 5.1 million passengers in 2018. The study aims to evaluate and analyze projected passenger terminal needs plans for 2022-2037. The development plan is carried out by forming a double linear regression equation between passenger volumes used asdepent variableswhile population numbers (Pdd) and Percapita PDRB on the Basis of Constant Price in 2010 (Pkt) of South Sumatra Province asindependent variables ) with the help of SPSS program version 25.00 and Microsoft Excel. Thus, the number of residents (Pdd) has a greater effect on the growth of domestic passengers. Based on KM Number 10 of 2010 on the Master Plan of Sultan Mahmud Badaruddin II Airport, there needs to be a development of this airport in the future. Based on the results of the development plan of this terminal passenger area in the 2037 plan year of 55. 324m2 with a capacity of 8,871,648 passengers per year and can accommodate 3,177 passengers during peak hours.
