Carrying capacity of coastal tourism need to be reviewed from the multiple aspect of ecology, physical, political and economic as well as socio-cultural. Then various indicators need to be formulated to make an assessment of the impact of coastal tourism development. The cases of coastal tourism could be an interesting topic to integrate the subject matter of geography. In this paper the framework of that carrying capacity is applied to Mandeh coastal tourism development in West Sumatra.

Jumlah penduduk di Kota Pariaman semakin bertambah dari waktu ke waktu. Seiring dengan meningkatnya jumlah penduduk maka kebutuhan lahan untuk permukiman dan non permukiman di Kota Pariaman juga akan mengalami peningkatan, sehingga  menjadi ancaman bagi ketersediaan lahan sawah di Kota Pariaman. Penelitian ini bertujuan menemukan kategori tekanan penduduk terhadap lahan sawah di Kota Pariaman yang meliputi lahan sawah yang memiliki tekanan rendah dan tekanan tinggi beralih fungsi. Faktor – faktor alih fungsi lahan sawah terdiri dari faktor situasi (eksternal) yaitu laju pertumbuhan penduduk, kepadatan penduduk, jarak dengan pusat primer, kelas jalan, rute angkutan umum yang melewati jalan dan jarak dengan fasilitas, faktor kebijakan yaitu kebijakan terkait sesuai dengan rencana tata ruang, kebijakan terkait sesuai dengan data dari LP2B, kebijakan terkait hamparan lahan sawah dan kebijakan terkait bentuk lahan sawah berdasarkan sistem pangairannya dan faktor site (internal) yaitu harga lahan sawah. Data yang digunakan adalah data sekunder yang diperkaya dengan data primer. Data primer berupa harga tanah yang dikumpulkan melalui wawancara kepada beberapa orang masyarakat, tuan tanah dan pengembang, Sedangkan data sekunder dilakukan melalui kajian kepustakaan dan data dari instansi pemerintah yang terkait, Analisis data dilakukan melalui metode checklist dan metode overlay peta menggunakan software Sistem Informasi Geografis (GIS). Hasil penelitian menunjukkan bahwa terdapat dua kategori tekanan penduduk terhadap lahan sawah di Kota Pariaman, yaitu tekanan penduduk terhadap lahan sawah tinggi dan tekanan penduduk terhadap lahan sawah rendah

Spatial plan is a reference in spatial development in Indonesia. One of the information displayed is landslides susceptibility area. Lima puluh kota regency in province of West Sumatra, which is located in the Bukit Barisan mountains, is a landslide-prone area, so that the regional spatial plan (RTRW) document contains a map of landslide susceptibility areas. This study evaluates the accuracy of the landslide susceptibility map contained in the regional spatial plan with landslide events in the regency until 2021, using the overlay method and then examining with the characteristics that affect it. The results of the study show that not all landslide events are in the locations indicated on the map in the spatial plan. It is necessary to improve the information on the landslide susceptibility map on a regional scale which has been based on the InaRisk map published by the BNPB (National Disaster Management Agency) on a small scale. In order to be more accurate with the causal factors, it is needed to improve the method of landslide susceptibility maps at the regional level. The methods that have been heuristic in nature need to be improved with statistical methods.

AbstrakTujuan dari penelitian ini adalah menganalisis hubungan antara karakteristik kependudukan di Kabupaten Padang Pariaman dengan variabel seperti sex ratio, beban ketergantungan, umur median, penduduk petani, tingkat kemiskinan, kepadatan agraris, kepadatan netto dan laju pertumbuhan penduduk. Analisis keterkaitan tersebut dilakukan dengan menggunakan korelasi Pearson r dan Chi Square. Dari hasil analisis ini ditemukan bahwa tingkat kemiskinan di Kabupaten Padang Pariaman dipengaruhi oleh besarnya laju pertumbuhan penduduk, dan tingginya umur median. Sedangkan karakteristik kependudukan lainnya tidak terlalu menunjukkan pengaruh yang besar terhadap tingkat kemiskinan. Khususnya kepadatan lahan pertanian ternyata berpengaruh lemah terhadap tingkat kemiskinan di Kabupaten Padang Pariaman. Kesimpulan yang dapat ditarik yaitu hubungan antar karakteristik demografis ditentukan juga oleh aspek lain khususnya ekonomi.Kata kunci : karakteristik kependudukan, korelasi, wilayah AbstractThe purpose of this study was to analysis of the relationship between population characteristics in Padang Pariaman Regency such as sex ratio, deployment ratio, median age, farmer population, poverty level, agrarian density, net density and population growth rate using Pearson r and Chi square. It was found that the poverty rate in Padang Pariaman Regency was influenced by the large rate of population growth, and the high median age. Whereas for other population characteristics it does not show a significant influence on the level of poverty. Especially agricultural land density affect the poverty level in Padang Pariaman Regency weakly. Conclusions that can be drawn is relationship among region demographic characteristics is also determined by other aspects particularly economy.

Landslide susceptibility zonation is necessary to be considered in land use planning at various scales., different approaches and analytical methods can be used to evaluate and zone the area and processed with GIS software. However, there are constraints in its use, such as the cost of the licenses of software and source code that cannot be accessed and evaluated by users. The recent development of open-source software that can integrate data, analysis, and graphs in a representation such as the R program, has opened up opportunities for researchers to reevaluate and modify interpretation further from available ones to address issues. In this regard, this study aims to create functions in R using the Weight of Evidence (WoE) method, a form of bivariate statistic approach to acquire the significant factors controlling landslides and generate a susceptibility map. The case study is located in Limapuluh Kota Regency, West Sumatra Province of Indonesia, a hilly and mountainous region where its districts are prone to landslides. Eight of eleven factors such as geology, landform, land cover, elevation, density of vegetation greenness, slope, rainfall intensity, and proximity to stream were regarded to control landslides which set up four classes of landslide susceptibility zone (very low, low, moderate, and high).
