Earthquake events caused thousands of families to be displaced, some inside refugee camps, others living in relatives’ houses, besides causing the stages of government, economy and Social Stage to experience many obstacles. Reconstruction implementation Community-based housing is the backbone for sustainable development. Through this approach, it is hoped that people can realize the importance of building a building using earthquake resistant building structures. Based Deskriftive analysis and factor analysis, there are 18 (eighteen) the risk of pre-construction project of housing reconstruction after the earthquake based society including the risk of unexpected (Undesirable). From 8 (eight) Stages of pre-construction phase of the housing reconstruction is 1 (One) Stages of risks are still acceptable namely Stages 6 (Stages of Establishment of Community Organizations). The greatest risk is in Stage 8 is R.8.16. The price of Building Materials which has the biggest risk value is: 5.389. With this risk analysis it is hoped that the parties concerned can pay more attention to the risks that have high value (categorized as an unexpected risk)”.

Permasalahan transportasi sangat sering terjadi seperti kemacetan, polusi udara, kecelakaan, antrian maupun tundaan biasa di jumpai dengan tingkat kualitas yang rendah maupun tinggi. Kota padang adalah salah satu kota diSumatra Barat dan merupakan kota industri dan pariwisata yang banyak menarik peminat penduduk di kota lain yang ikut berkunjung. Jln. Khatib Sulaiman pada simpang empat bundaran merupakan salah satu simpang yang terletak di simpang presiden. Arus lalu lintas yang melalui simpang tersebut tersebut cukup padat pada waktu-waktu jam sibuk. Sehingga terdapat aktivitas padat di jalan ini seperti angkutan umum yang berhenti untuk naik dan menurunkan penumpang, kendaraan yang parkir di badan jalan serta kendaraan yang keluar masuk disamping jalan darilingkungan sekitar simpang. Penelitian ini bertujuan untuk menganalisis atau mengevaluasi arus jenuh pada simpang empat bundaran Khatib Sulaiman saat ini dengan memberikan alternatif pemecahan masalah yang tepat pada simpang tersebut. Sifat dari penelitian ini adalah analisis, penelitian dilakukan satu minggu penuh dari hari senin sampai minggu dan di mulai pada pukul 07:00-09:00, 12:00-14:00, sampai 16:00-18:00. Dari hasil penelitian yangdilakukan maka didapat nilai kapasitas sebagai berikut: Kapasitas (C) = 1921,01 SMP/jam, Penelitian kapasitas jalan Teuku Umar kurang memadai disebabkan tingkat pelayanan jalan (LOS) mencapai 2,3 dimana dengan nilaitersebut sering terjadi kemacetan dan antrian panjang dengan tingkat pelayanan F dan berdasarkan banyak jumlah pengguna kendaraan Di Jl Khatib Sulaiman arah simpang DPRD pada jam sibuk yaitu hari senin jam 16.00 – 18.00 adalah sebesar 3291,3.

The coastal environment is an area that always changes. It depends on the power balance between topography, rocks, and its nature with tidal and wind waves. Progress in the Purus sub-district resulted in an increase in the amount of groundwater demand. If this happens, it can cause a drawdown so that the well water of the residents feels brackish or feels salty. This study aims to determine the salinity of shallow well water when viewed from the distance of the well to the coastline (x1) and groundwater level (x2) in Purus Padang Village. This type of research is field research (field research), using a quantitative approach. The sample was taken as many as 18 wells in Purus. The results showed that the salinity of well water occurred unevenly in Purus Village. If the distance of the well is further away from the coast, the salinity value will be lower. If the depth (height) of the water table is getting farther away from the sea level, the salinity value will be higher. For consumption, the salinity content in Purus Village is still within normal limits (<250 mg/l). The spread of salinity is caused by the flow of surface water.

Liquefaction is a condition of continuous soil mass deformation at residual stress due to increasing pore water pressure that results in effective stress reduced. This study was conducted to identify the potential hazards of liquefaction in the Jondul Rawang area in Padang City. This study is to observe the soil contour and characteristics. Primary data obtained by observing the soil contour, soil characteristics, and the form of buildings, etc. Whilst, secondary data obtained from the related documents as supporting data. The results concluded that the Jondul Rawang area is potentially liquefaction area where the soil contours and characteristics could be classified as peat soil and lied in the swamps. Furthermore, if the rainfall intensity increase then flooding occurred. Then as consequences, there were many residential houses and other buildings around the area turning into tilted and drowned due to the degradation of soil bearing capacity. Therefore, requiring disaster management efforts against the threat of liquefaction in that area, both in terms of the drainage system due to flooding and overall repairs for the sewerage could work well.
