Abstract

The purpose of this research is to analyze the value of erosion factors and the level of erosion hazard using the RUSLE method in the Lisun Sub Watershed, Nagari Silokek, Sijunjung Regency. This type of research is quantitative research. The results show that: 1) The erosion factor that most influences the low erosion that occurs in the Lisun Subwatershed is CP where the Lisun Subwatershed still has a very large forest area of 28,886.33 ha (70%) with high forest density so that the amount of erosion can still be controlled.2) The level of erosion hazard in Lisun Sub-watershed includes very light to heavy and consecutive land area in Lisun Sub-watershed from very light 0.247 tons/ha/year (30.65%), light 5.047 tons/ha/year (40.69%) medium 23.007 tons/ha/year (14.33%) and heavy 106.882 tons/ha/year (14.28%) with total erosion of 135.184 tons/ha/year.

Abstract

This research aims to map the level of landslide danger and analyze the factors that cause landslides in IV Koto District, Agam Regency. The research method uses a quantitative approach with frequency ratios to determine the level of landslide danger and Pearson correlation to analyze the factors that cause landslides in District IV Koto. The research results show that the level of landslide danger is divided into four categories: not dangerous covering 48% (3.868,989 hectares), slightly dangerous 26% (2.033,912 hectares), dangerous 14% (1.137,001 hectares), and very dangerous 12% (949,303 hectares) of total area of ​​the research area. Based on Pearson correlation analysis, the most dominant factor causing landslides in IV Koto District is geology with a positive correlation value of 0.894 to the level of landslide danger, indicating that the geological structure has a very strong influence on landslide events in the area.

Abstract

Model spasial bahaya banjir di Daerah Aliran Sungai Sikilang,’  Pasaman Barat mempunyai tujuan untuk analisis intensitas hujan 2024-2034-2044, memodelkan penggunaan lahan dan tutupan lahan’’ tahun 2024-2034-2044, model numerik banjir, dan model mitigasi banjir melalui tindakan konservasi. ‘Metode yang digunakan dalam penelitian ini adalah metode kuantitatif’’. Hasil penelitian menunjukkan bahwa intensitas hujan meningkat seiring dengan bertambahnya kala ulang,’ selanjutnya’  perubahan penggunaan lahan dan tutupan lahan’ di DAS Sikilang mengalami penurunan yaitu semak belukar,’ hutan sekunder, hutan primer, lahan terbuka, sawah, kebun campuran, ladang, lahan terbangun, sedangkan penggunaan lahan yang mengalami peningkatan luasan yaitu perkebunan kelapa sawit’’dan ’lahan terbangun’’. Model numerik banjir di DAS Sikilang menunjukkan bahwa puncak banjir (Qp) membutuhkan waktu 6,50 jam, waktu yang dibutuhkan untuk mengurangi debit banjir (Tp+0,3) yaitu 11,74 jam, dan waktu yang diperlukan untuk mengurangi debit banjir (Tp+T0,3+1.5T0,3) adalah 19,60 jam. Model spasial banjir di DAS Sikilang tahun 2024 sampai tahun 2044 mengalami perubahan yang signifikan.’ Perubahan luas area terdampak banjir’’ tahun 2024 sampai tahun 2034 pada kelas kedalaman tinggi meningkat sebesar 694,667 ha, kelas kedalaman sedang meningkat 277,881 ha,  kelas kedalaman rendah meningkat 30,017 ha ,  perubahan luas area terdampak banjir tahun 2034 sampai 2044 pada kelas kedalaman tinggi meningkat sebesar 215,208 ha,  kelas kedalaman sedang menurun 75,842 ha dan kelas kedalaman rendah meningkat 4,42 ha’. Perubahan penggunaan lahan dan tutupan lahan 2024 sampai tahun 2034 mempengaruhi debit banjir 36,303 %, dan perubahan  penggunaan lahan dan tutupan lahan tahun 2034 sampai tahun 2044 mempengaruhi debit banjir 11,951%. Sebagai langkah mitigasi banjir, dilakukan model mitigasi banjir melalui tindakan konservasi, pada hulu DAS Sikilang,. Upaya mitigasi ini dapat mengurangi debit banjir pada tahun 2024 sebesar 4,744 m3/detik, pada tahun 2034 mengurangi debit banjir sebesar 34,647 m3/detik, dan pada tahun 2044 mengurangi debit banjir 47,303 m3/detik. Untuk mengantisipasi bahaya banjir kepada masyarakat yang tinggal di DAS Sikilang, perlu diinformasikan bahwa banjir akan terjadi apabila intensitas hujan >11 mm/jam dengan durasi 4,64 jam, maka waktu yang dibutuhkan untuk mencapai puncak banjir adalah 6,50 jam, sehingga masyarakat dapat mengambil langkah antisipasi guna mengurangi potensi kerugian akibat banjir tersebut. Kata kunci: Penggunaan lahan dan tutupan lahan, Nilai Koefisien Aliran, Banjir, Model Spasial

Abstract

The research aims : 1) analysis hydraulic model in numeric modeling of flow Bayang watershed, 2) modeling spatial flood of Bayang watershed using HEC-RAS. Type thi research uses quantitative method with spatial approach. The data used for flood discharge is maximum rainfall in 2013-2022. Data were analysis using unsteady flow technique with software HEC-RAS and literature study. 1) The study produces 100 year periode discharge with a peak time of 1.27 hours which produces a period 2 year of 263.98 m3/sec, period 5 of 303.08 m3/sec, period 10 of 328.95 m3/sec, period 25 of 361.70 m3/sec, period 50 of 385.95 m3/sec and period 100 0f 410.07 m3/sec. 2) The model produce 1-D and 2-D models, the 1-D model produc a flood overflow depth of 3.03 to 1.71 meters while the 2-D model produce a flood overflow depth of 3 to 2 meters, villages of Sawah Laweh, Pasar Baru, Talaok, and Koto Barapak.

Abstract

The city of Padang Panjang, with its undulating topography, faces difficulties in utilizing land for settlement as population growth increases. This study aims to analyze the carrying capacity and accommodating capacity of residential land in the city. Descriptive quantitative research methods with data presented through tables and maps, calculations refer to the Ministry of Environment's 2014 carrying capacity guidelines and the Guidelines for Housing and Settlement Area Development and Development Plan (RP3KP). The results showed that in 2022, Padang Panjang City has a Settlement Carrying Capacity (DDPm) value of > 1. Kelurahan Ganting achieved the highest score of 14.4 and Kelurahan Pasar Baru had the lowest score of 1.8. The area of land suitable for settlement is around 672 hectares, can accommodate 264,309 people with a total of 66,077 housing units. Kelurahan Kampung Manggis stands out with a high capacity, able to accommodate around 34,864 people, while Pasar Baru has the lowest capacity, only 503 people.

Abstract

Tourism activities are not supported by technology so that tourism potential is not optimally utilized. The platform designed for tourism in Pulai Anak Air is WebGIS Taourism. The program is carried out by involving the Pulai Anak Air Village Government, POKDARWIS, Homestay Managers, and local MSMEs. The method used is Focus Group Discussion (FGD) and training with WebGIS Tourism data management practices and updates that involve participants directly. The number of participants is 10 people who are representatives of each Institution. The results achieved are that training participants are able to update data in real time according to the needs of tourism, homestays, and MSMEs. Based on the evaluation conducted by the Community Service Team of training participants, it was found that 6 out of 10 participants were able to manage WebGIS Tourism independently. In addition, the sustainability of the program carried out by the team is in the form of regular mentoring related to website management.
