Abstract

Flooding in Indonesia tends to increase from year to year, and one of the causes is high rainfall. Padang City is one of the areas that has high rainfall intensity which can trigger flooding. This research aims to present spatial information on flood-prone areas by processing data in Google Earth Engine (GEE) and determine the level of flood vulnerability in Padang City. GEE is a platform capable of processing geopatial data on a large scale using multi-temporal imagery and utilizing cloud computing technology that allows solving large problems in a short time. This research uses CHIRPS Dayli data: Climate Hazard Group Infrared Precipitation, NASA SRTM Digital Elevation 30 m, Sentinel 2-A and research administrative boundaries. This study uses rainfall, elevation, TPI, NDWI and NDVI parameters. Data analysis and processing in this study were fully carried out in GEE. The results showed that the area very prone to flooding has an area of 5569.46 ha or 8.03%. The prone area is 28064.57 ha or 40.46% and the non-prone area is 35726.20 ha or 51.51%. The results of this research are expected to help the government in flood mitigation in Padang City.

Abstract

Kemacetan lalu lintas merupakan persoalan yang terus mengalami peningkatan, khususnya di wilayah perkotaan seperti Kota Padang. Salah satu lokasi yang menjadi titik rawan kemacetan adalah di Simpang Bundaran DPRD Provinsi Sumatera Barat. Di lokasi ini ditemukan panjang antrian dan waktu tundaan yang tinggi, yang disebabkan oleh desain simpang yang kurang efisien, keberadaan bundaran yang tidak berada di posisi simetris, serta perilaku pengguna jalan yang kurang disiplin. Penelitian ini bertujuan untuk mengevaluasi kinerja simpang eksisting dengan menggunakan metode MKJI 1997 dan PKJI 2023, serta melakukan perencanaan ulang terhadap geometri simpang untuk meningkatkan efisiensi lalu lintas. Metode penelitian mencakup pengumpulan data volume lalu lintas, data geometrik, dan data sinyal yang diperoleh dari hasil survei di lapangan. Kemudian, dilakukan analisis kapasitas serta tingkat pelayanan dengan pendekatan teoritis dan simulasi mikroskopik menggunakan perangkat lunak Autodesk Civil 3D dan PTV VISSIM. Hasil kajian menunjukkan bahwa kondisi simpang saat ini menghasilkan panjang antrian hingga 55,30 meter dan rata-rata tundaan sebesar 47,61 detik per satuan mobil penumpang (smp). Alternatif perencanaan ulang dilakukan dengan menghapus bundaran dan mengganti konfigurasi simpang menjadi simpang bersinyal dengan rancangan geometri yang lebih optimal. Hasil simulasi desain tersebut menunjukkan peningkatan kinerja simpang, ditandai dengan menurunnya panjang antrian menjadi 23,99 meter dan tundaan menjadi 16,58 detik per smp. Dengan demikian, perencanaan ulang ini terbukti mampu meningkatkan efisiensi arus lalu lintas dan diharapkan dapat dijadikan acuan dalam perbaikan manajemen lalu lintas di simpang-simpang strategis lainnya di Kota Padang.

Abstract

Air Tawar Barat Village is included in the High-Risk Zone (area with a high level of vulnerability to tsunamis) in Padang City, so very severe damage likely occurs in the event of a tsunami. The characteristics of the tsunami in Padang City are local tsunamis or short-range tsunamis, where the time interval for tsunami arrivals is between 20-30 minutes. Based on these conditions, a tsunami evacuation route is urgently needed by the community. The current evacuation route is still ineffective because the distance that must be covered is 3-5 km in less than 30 minutes. This study aims to evaluate the evacuation routes that are less effective by comparing the evacuation routes from the government with the results of GIS analysis. The method used in this research is Network Analyst. The results of this study found that the time needed to evacuate was 10 minutes by going to 26 P-TES. Where 24 P-TES are located on the UNP campus, 1 is in the Air Tawar Timur Village and 1 is a planned P-TES. The evacuation route generated from the results of the GIS analysis is more effective than the route from the government because the route to P-TES is closer than having to leave the tsunami zone so that it is more likely to be taken by the community.

Abstract

Since the inactivity of the Bingkuang Regional Terminal in 2009, the city of Padang no longer has a bus terminal, which causes many shadow terminals in the city of Padang. In 2021, the Type A Terminal in Padang City was completed and tested immediately since not October 2021. However, since the trial until now this terminal is still quiet for buses and the public to visit. Then in 2021, the Type A Terminal in Padang City was completed and tested immediately since not October 2021. However, since the trial until now this terminal is still quiet for buses and the public to visit. Anak Air Type A Terminal is still quiet due to its location which is far from the city center, and access to the Anak Air Type A Terminal is considered quite difficult. The formulation of the problem in this study is how the perception of the Trans Padang bus driver on the location of the Anak Air Type A Terminal and the completeness of the facilities it has. The standard used in this study is the Decree of the Director General of Land Transportation No. 31 of 1995 concerning Road Transportation Terminals. The purpose of this study was to find out and provide the opinion of bus drivers on the existence of Anak Air Type A Terminal in Padang City and determine the feasibility of the Anak Aia Terminal based on the facilities it has. The method used in this research is qualitative type. The sample in this study was the Trans Padang bus driver. The data were collected by using interview techniques with Trans Padang bus drivers who enter the Anak Air Type A Terminal every day, observations at the terminal location to record the facilities that this terminal already has and documentation in the form of photographs. The results of the research that has been carried out through interviews with Trans Padang bus drivers found 3 keywords, namely the location of the terminal which is considered appropriate, access to the terminal is difficult to pass and there are still many facilities that are not yet available at Anak Air Type A Terminal.
