Abstract

Perubahan iklim dan aktivitas antropogenik menyebabkan tekanan signifikan terhadap sumber daya air, mempengaruhi keseimbangan ketersediaan dan kebutuhan air di berbagai daerah aliran sungai. Penelitian ini bertujuan mengevaluasi ketahanan sumber daya air (water resilience) di hulu DAS Batang Arau, Kota Padang dengan menggunakan pendekatan terpadu berbasis pemodelan hidrologi SWAT dan analisis Reliability, Resilience, Vulnerability (RRV). Metode penelitian meliputi: (1) karakterisasi morfometri DAS dengan menganalisis 19 parameter morfometri; (2) pemodelan SWAT dengan kalibrasi-validasi yang menghasilkan nilai performa bervariasi (R² = 0,54-0,97) dan sangat baik (NSE = 0,79-0,89); (3) analisis keseimbangan supply-demand; serta (4) evaluasi ketahanan air dengan pendekatan RRV. Hasil analisis morfometri menunjukkan DAS memiliki bentuk memanjang (Form Factor 0,25) dengan kerapatan drainase sedang (1,40 km/km²). Pemodelan SWAT menghasilkan debit andalan Q80 sebesar 1,51 m³/s yang masih mencukupi total kebutuhan air 0,63 m³/s (domestik 0,0234 m³/s; pertanian 0,4252 m³/s; industri 0,1811 m³/s), dengan Water Availability Ratio (WAR) 1,427. Analisis RRV menghasilkan Indeks Keberlanjutan DAS (IKDAS) sebesar 0,85 (sangat baik), didukung oleh keandalan tinggi (1,0), ketahanan baik (0,84) dengan tutupan hutan 87,9%, namun masih menghadapi kerentanan signifikan (0,65) terutama akibat tingkat erosi tinggi (385,6 ton/ha/tahun) dan area rawan banjir (34,63%). Rekomendasi pengelolaan meliputi teknik konservasi tanah-air, sistem peringatan dini banjir, perluasan zona riparian, dan penguatan kelembagaan pengelolaan kolaboratif untuk mengintegrasikan kepentingan berbagai pemangku kepentingan. Pendekatan RRV terbukti efektif untuk evaluasi komprehensif kondisi DAS dan perumusan prioritas intervensi strategis.

Abstract

Batu Tanjung Village is located in Sawahlunto City, West Sumatra, which is better known as coal mines village. Therefore, its agricultural and livestock potential has not been developed and utilized optimally. Generally, the people work as farmers, however they do not know in detail about the potential of the agricultural and livestock sectors. This community service activity aimed to (1) explore the actual potential of the agricultural sector, and (2) mapping the potential of the agricultural sector on participatory base and GIS. The methods used in this activity were survey of agricultural potential, participatory mapping using the Participatory Rural Appraisal (PRA) method, SWOT analysis for developing strategies of agricultural and livestock sectors. The results of this activity show the superior potential of the village, namely rice (320 ha), rubber (76 ha), cocoa (9 ha), coconut (32 ha), and areca nut (35 ha). The potential for the food sector is almost evenly distributed in all hamlets in Batu Tanjung Village. Some of the leading potentials in the livestock sector in Batu Tanjung Village are buffalo (239), cows (141), purebred chickens (6264) and quail (996). The conclution of this activity shown the potential of the village's agricultural and plantation sectors, namely rice, corn, rubber, cocoa, areca nut and coconut which are spread throughout all hamlets in Batu Tanjung Village. The potential for the livestock sector are buffalo, cows and laying hens. Furthermore, this activity also produced a potential map of the agricultural, plantation and livestock sectors of Batu Tanjung Village with a scale of 1:120 and was submitted to the Head of Village.

Abstract

This research has been carried out to identify areas that were suitable for planting superior crops in Nagari Lawang, Matur District, Agam Regency. This research was conducted using the matching method and then was continued with scoring of the slope, rainfall, C-Organic, soil pH, and soil texture parameters. The obtained values ??were used to determine the classification of land suitability for sugar cane, corn, peanuts and shallots. Land with the potential for planting sugar cane, corn, peanuts, and shallots is land in the very suitable (S1) and suitable (S2) suitability classes. Several commodities can be planted on a piece of land depending on the suitability of the characteristics of the land to the conditions for growing plants. The results of the analysis show that the land in Nagari Lawang that is suitable for planting sugar cane is 380.23 ha (27.57%), corn is 380.23 ha (27.57%), peanuts is 362.57 ha (26.29%), and shallots is 380.23 ha (27.57%) of the total land area of ??Nagari Lawang. Nagari Lawang's land (2023) that has been planted (S1 and S2 classes) with sugar cane covers an area of ??184.26 ha, corn covers an area of ??2.6 ha, peanuts covers an area of ??2.09 ha, and shallots covers an area of ??0.12 ha. The potential for developing sugar cane is 195.97 ha, corn is 377.63 ha, peanuts is 360.48 ha and shallots is 380.11 ha, respectively.
