Abstract

Pollution of water will have an impact on the ecological aspects, social, cultural and economical too. Thus the effort necessary improvements and countermeasures against polluted river costly when compared with the benefits derived from the river. One of the environmental problems that arise in the city of Padang was pollution in some rivers. This causes a decrease in the quality of river water, while known to the river is a source of water that is still used by people who live along the river flow. But on the other side of the river is one of the shelters of waste water or waste originating from a variety of activities such as residential population, household industry and market. Padang city, there are several rivers flowing along the residential areas in between Sungai Batang Arau, Batang Kandis, Batang Kuranji and others. Therefore, the quality of the river should be maintained so communities along the river can exploit. Capacity calculation is done on the river Batang Kuranji divided by five (5) sections calculations. These considerations are based on the same type of pollutant sources resulting in decreased water quality Kuranji Batang River, their tributaries were in and out of Sungai Batang Kuranji.Keywords: Quality, Capacity, Pollution

Abstract

Perkembangan penggunaan tanah secara spasial di Nagari Cubadak dibatasi oleh faktor fisik yang didominasi oleh kemiringan landai dan agak sedikit curam. Penelitian ini dilakukan dengan tujuan untuk  mengetahui dan menganalisis Penggunaan tanah dan Pola perubahan penggunaan tanah untuk pertanian secara spasial di Nagari Cubadak. Penelitian ini menggunakan metode yang dilakukan adalah metode interpretasi citra penginderaan jauh, metode survey, dan analisis deskriptif berbasis keruangan. Interpretasi citra penginderaan jauh dilakukan untuk mengetahui informasi jenis penggunaan lahan khususnya pertanian aktual dan tahun-tahun terdahulu berdasarkan nilai digital yang terekam pada data penginderaan jauh. Dari penelitian ini dapat disimpulkan bahwa, Penggunaan tanah di Nagari Cubadak bisa diklasifikasikan delapan (8) jenis penggunaan lahan yakni; Bangunan Umum, Fasilitas Olahraga, Kolam, Makam, Perumahan, Sawah, Tanah Kosong, Tegalan dan Tempat Ibadah. Kemudian, pengurangan penggunaan tanah 1990–2000 yang paling banyak terdiri dari penggunaan tanah tegalan dengan 91 kavling, paling banyak berubah menjadi perumahan sebanyak 75 kavling, kemudian pengurangan sawah dengan 25 kavling, paling banyak berubah menjadi tegalan dengan 35 kavling dan kolam 20 kavling dengan pengurangan 52 kavling.The development of spatial land use in Nagari Cubadak limited by physical factors which are dominated by sloping slopes and slightly steep. This research was conducted with the aim to find out and analyze land use and the pattern of changes in land use for agriculture spatially in Nagari Cubadak. This study uses the method used is the method of interpretation of remote sensing images, survey methods, and spatial-based descriptive analysis. Interpretation of remote sensing imagery is done to find out information on the type of land use, especially actual and previous years based on digital values recorded on remote sensing data. From this study it can be concluded that, Land use in Nagari Cubadak can be classified as eight (8) types of land use namely; Public Buildings, Sports Facilities, Swimming, Graves, Housing, Paddy Fields, Empty Land, fields and places of worship. Then, the reduction in land use from 1990 to 2000 which mostly consisted of the use of upland land with 91 plots, at most turned into housing lots of 75 plots, then reduced fields with 25 plots, most changed to moor with 35 plots and pools of 20 plots with subtraction 52 lots.

Abstract

Perkembangan penggunaan tanah bergerak horisontal secara spasial ke arah wilayah yang mudah diusahakan. Penggunaan tanah juga bergerak secara vertikal dalam rangka menaikkan mutunya. Penelitian ini bertujuan untuk menganalisis pola penggunaan lahan, bagaimana manajemen penggunaan lahan di satu wilayah berdasarkan batas Nagari. Metode yang digunakan adalah analsisis spasial dengan interpretasi citra penginderaan jauh, survey lapangan, dan analisis deskriptif. Pertumbuhan pemukiman Nagari Sungai Sariak Kecamatan VII Koto Kabupaten Padang Pariaman mengakibatkan pemanfaatan ruang menjadi tumpang tindih. Diperlukan cara-cara pengelolaan dan managemen penggunaan tanah dalam rangka pembangunan berkelanjutan yang menaikkan taraf hidup masyarakat dan tidak menimbulkan kerugian lingkungan.Terdapat 9 jenis penggunaan lahan yang ada di Nagari Sungai Sariak. Penggunaan lahan tersebut adalah Primary Forest, Secondary Forest, Paddy Field, Settlement, Mixed Plantations, Crop Fields, Water Bodies, Bushes, dan Plantations. Penggunaan lahan yang paling luas di Nagari Sungai Sariak adalah jenis penggunaan lahan Primary Forest, sebesar 48% dari total luas wilayah Nagari Sungai Sariak. Pada tahun 2011 sampai tahun 2016, penggunaan lahan paling luas terjadi pada penggunaan lahan jenis Primary Forest yang kemudian menjadi Mixed Plantations. Land use Changes moved horizontally spatially towards areas that are easily cultivated. The land use also moves vertically in order to increase its quality. This study aims to analyze land use patterns, how land use management in one area is based on Nagari boundaries. The method used is spatial analysis with interpretation of remote sensing images, field surveys, and descriptive analysis. The growth of Nagari Sungai Sariak in Kecamatan VII Koto, Kabupaten Padang Pariaman resulted in overlapping use of space. Management methods are needed and management of land use in the framework of sustainable development that raises the standard of living of the community and does not cause environmental losses. There are 9 types of land use in the Nagari Sungai Sariak. The land uses are Primary Forest, Secondary Forest, Paddy Field, Settlement, Mixed Plantations, Crop Fields, Water Bodies, Bushes, and Plantations. The most extensive land use in Nagari Sungai Sariak is the type of Primary Forest land use, amounting to 48% of the total area of the Nagari Sungai Sariak. From 2011 to 2016, the most extensive land use occurred in Primary Forest land uses which later became Mixed Plantations.

Abstract

Watershed management will rely on biophysical activity such as erosion control, reforestation of critical lands, and institutional dimensions such as incentives and regulations related to the economic field. The social dimension in watershed management is more directed to understanding local socio-cultural conditions and using these conditions as a consideration for planning strategies for effective and efficient high-flow watershed management activities. As one of the existing resources, the river flow needs to get attention, both from the community and from the government. From the management of water resources can be traced to environmental damage, especially on erosion. Environmental damages, whether they are influenced by humans or caused by the natural conditions themselves, can be seen from the symptoms and phenomena of river flow behavior from time to time. The state of the river will be worrying if left constantly. This condition could have an impact on the community such as people's houses, rice fields, roads and community estates will be eroded along the river in Nagari Sungai Sariak. This problem is very necessary to be investigated because if left without any effort from the community and the government will have an impact on environmental damage that resulted in fatal damage to the environment, rice fields and homes surrounding the river will erode. It is hoped that by doing this research will be an input for the community and local government in managing the River.

Abstract

Penelitian ini adalah penelitian deskriptif dengan metode survey, Metode yang digunakan dalam tahap analisis tabuler adalah metode scoring berdasarkan hasil penelitian lapangan yang telah dilakukan. Setiap parameter penentu tingkat bahaya longsor diberi skor tertentu. Setiap unit analisis skor tersebut dijumlahkan dan hasil penjumlahan skor selanjutnya diklasifikasikan untuk menentukan tingkat bahaya longsor. wilayah Kota Padang Panjang terbagi atas 3 potensi rawan longsor yaitu: (1) Tingkat sedang, (2) Tingkat rendah dan (2) Tidak rawan. Bahaya Longsor tingkat sedang terdapat di sebagian Kelurahan Bukit Surungan, Pasar Usang, Koto Katik, Koto Panjang, Ganting, dan Sigando, dan Silaing Bawah. Pada Zona ini dapat terjadi longsor jika curah hujan di atas normal, terutama pada daerah yang berbatasan dengan lembah sungai, gawir, tebing jalan atau jika lereng mengalami gangguan. Untuk bahaya longsor tingkat rendah yaitu terdapat di hampir sebagian besar wilayah Kota Padang panjang, bisa dikatakan hampir 2/3 bagian Kota Padang Panjang digolongkan pada kawasan dengan tingkat bahaya longsor rendah. Dan untuk kawasan yang tidak rawan longsor terdapat di sebagian Kelurahan Ganting, Silaing Bawah, Silaing Atas, Kampung Manggis, dan Bukit Surungan. This research is a descriptive research with survey method, the method used in the tabular analysis stage is the scoring method based on the results of field research that has been done. Each parameter determining the level of landslide hazard is given a certain score. Each unit of score analysis is summed and the sum of the results of the next score are classified to determine the level of landslide hazard. The area of Padang Panjang City is divided into 3 potential landslide hazards, namely: (1) Medium level, (2) Low level and (2) Not vulnerable. Medium level landslide hazards are found in parts of Bukit Surungan, Pasar Usang, Koto Katik, Koto Panjang, Ganting, and Sigando, and Silaing Bawah. In this zone landslides can occur if the rainfall is above normal, especially in areas bordering river valleys, swamps, road cliffs or if the slopes experience interference. For low level landslide hazards, which are found in most parts of the city of Padang Panjang, it can be said that almost 2/3 of the city of Padang Panjang is classified as an area with a low level of landslide. And for areas that are not prone to landslides, there are some in Ganting, Silaing Bawah, Silaing Atas, Manggis, and Bukit Surungan.
