Bencana kelongsoran di perbatasan Sumbar Riau sudah beberapa kali terjadi, dari tahun 2006 sampai tahun 2016, terdapat 29 kali kelongsoran dan tanah amblas di lebih 80 titik kelongsoran. Banyak faktor penyebab kelongsoran, seperti tekstur tanah, kemiringan lereng, permeabilitas tanah, tingkat pelapukan batuan, kedalaman muka air tanah, curah hujan, beban gempa, dan kurangnya tumbuhan. Akibat kejadian kelongsoran (bencana longsor 3 Maret 2017), jalan banyak tertutup oleh material longsor sehingga beberapa waktu terputus rute jalan Sumbar dan Riau. Menyebabkan 7 orang meninggal dan banyaknya kerugian materil serta terputusnya perjalanan darat selama 2 hari dan menimbulkan kerugian secara ekonomi. Tujuan penelitian ini adalah menganalisa faktor penyebab kelongsoran tersebut. Metode yang dilakukan, pengumpulan data sekunder (photo udara dan peta situasi kawasan dari dokumen terdahulu), survey lapangan pengambilan photo situasi langsung, menganalisis dan mengelompokkan jenis kelongsoran, menentukan penyebab kelongsoran, dan mengklasifikasikan faktor dominan penyebab kelongsoran. Dari analisa data-data yang ada, penyebab kelongsoran ialah akibat adanya pertambangan batubara dan non logam, penebangan pohon-pohon untuk perkebunan, dan pemotongan lereng bagian atas untuk aktifitas manusia. Selain itu juga disebabkan akibat curah hujan yang cukup tinggi (3500 mm/tahun-4000mm/tahun). Di beberapa lokasi, kemiringan lereng cukup curam, yaitu dengan kemiringan 25o hingga besar dari 45o.

West Padang sub-district is a sub-district that has tourism potential, because in this sub-district there is a tourist attraction Puruih beach or what is known as Padang beach. As a tourist area, this sub-district still has problems with the availability of toilets and inadequate sanitation, as well as the habits of the people who still use the coast as a place to defecate. This habit will certainly cause new health problems later if you continue to let it. In addition, there are also many people who do not have their own MCK at home, and are forced to use public MCK for bathing and defecating and urinating. However, currently there are very few public toilet facilities in this area and if they do exist they are in a dilapidated condition. Added to this is the behavior of the surrounding community who do not take care of the public MCK facilities that have previously been built. In this study, researchers wanted to see changes in people's behavior after sanitation facilities were built in their area. Are they going to maintain the facilities that have been provided or are they the same as before, let the facilities be abandoned as before.

Land acquisition for the construction of toll roads is a key component of growth, however property acquisition has run into challenges. One of these challenges is that there hasn't been an adequate amount of community involvement and social and political studies of the impacted communities, which puts the community at risk while also impeding the efficient building of toll roads. With the use of the variables of community culture, political will, land governance, and community involvement in the decision-making process, this study tries to explain the elements that affect the decision-making process in land acquisition planning. The research strategy is a quantitative. 325 respondents completed questionnaires distributed to the impacted neighborhoods, which were used to gather research data. The data was then analyzed using structural equation models (Structural Equation Models) utilizing the AMOS application and the Sobel test. According to the study's findings, the decision-making process was significantly influenced by community culture, political will, and land governance. In light of community cultural characteristics such as political will, land governance, and community involvement, the study's conclusion shows that a model for land acquisition policy decision-making exists.

The strategy that might be applied to increase the use of public transportation is to apply space utilization incentives and disincentives. Incentives and disincentives for space use contain elements of regulation and control that are accommodating to various actual changes that occur in cities. The stages of this research are: : 1) distribution of questionnaires, 2) ranking of Alternative Incentives and Disincentives with Likert scale. The formulation of incentives and disincentives for space utilization that are predicted to increase the use of public transportation, Alternative incentives sequentially are: 1) Policy for subsidizing public transportation fares, 2) Policy for Rejuvenating Public Transport Fleet, 3) Improving infrastructure and supporting facilities for the use of public transportation, and for Disincentives: 1) Progressive Tax Implementation Policy on vehicle ownership, 2) Mandatory garage policy for prospective owners of private vehicles. The results of this study can be used as input for the Payakumbuh City government in making decisions related to spatial planning and transportation and further research needs to be done on alternative incentives and disincentives that have been formulated.

Kabupaten Agam merupakan salah satu kabupaten terbesar yang ada di provinsi Sumatera Barat. Didalam Kabupaten Agam tersebut terdapat salah satu kawasan wisata yaitu kawasan wisata Pantai Tiku yang berada di kecamatan Tanjung Mutiara. Berdasarkan tinggi dan pesatnya pengunjung di kawasan Pantai Tiku tersebut maka dilakukan pengembangan kawasan wisata pantai Tiku di Kabupaten Agam tersebut yang nantinya akan berdampak positif terhadap kepuasan pungunjung yang nantinya akan lebih besar menarik minat wisatawan berkunjung ke kawasan wisata Pantai Tiku. Selain berdampak positif pengembangan tersebut juga berdampak negatif seperti teningkatan volume lalulintas akan menimbulkan ketidakseimbangan antara jumlah lalulintas yang di bangkitkan dan kapasitas jalan di sekitar kawasan pantai Tiku. Penelitian ini bertujuan untuk menganalisis dampak lalulintas disekitar kawasan akibat pengembangan kawasan wisata pantai Tiku. Analisis yang dilakukan meliputi analisis bangkitan dan tarikan, analisis kinerja ruas jalan, dan analisis penanganan dampak lalulintas pada kondisi lalu lintas eksisting, masa konstruksi dan operaional. Hasil penelitian menunjukkan bahw pada kondisi lalu lintas eksisting didapatkan nilai V/C Ratio pada ruas jalan raya Tiku sebesar 0,25 dengan tingkat pelayanan B, kemudian pada kondisi lalu lintas masa konstruksi memiliki nilai V/C ratio sebesar 0,28 dengan tingkat pelayanan B pada tahun 2023 dan 0,29 dengan tingkat pelayanan masih B pada tahun 2024, kemudian selanjutnya pada kondisi lalu lintas masa operasional pada ruas jalan raya Tiku memiliki nilai V/C ratio sebesar 0,30 dengan tingkat pelayanan B pada tahun 2025 dan 0,38 dengan tingkat pelayanan masih B pada tahun 2030 atau 5 tahun setelah pengembangan.

This research addresses the problem of public knowledge of uninhabitable houses and the difficulty in identifying houses that do not meet community housing standards, to provide criteria for uninhabitable houses as well as optimize the rehabilitation assistance budget carried out by the Government. This research uses a quantitative descriptive method by collecting data through questionnaires, field observations, and documentation on 69 sample houses. The results of the analysis categorize the level of damage to the house into three categories, namely heavy, moderate, and light damage. From the research results of 69 sample houses, it was found that only 59 houses met the requirements for the uninhabitable house rehabilitation assistance program. In optimizing the allocation of aid funds, the level of damage to the house must be taken into account. With a more objective approach, rehabilitation housing programs can be more effective and provide greater benefits to people in need.
