Abstract

This study aimed to present a comprehensive evaluation of land suitability for wetland paddy cultivation in Paser Regency, East Kalimantan Province using the Simple Additive Weighting (SAW) process and Geographic Information System (GIS) techniques. The ten factors determining land suitability selected were soil texture, soil depth, soil drainage, soil type, rainfall, temperature, slope, distance from roads, distance from rivers and land use. The factor weights were considered the same, for the suitability analysis of the use of rice development in the study area. Then, after carrying out a weighted sum analysis, Paser Regency was qualitatively categorized as very suitable, quite suitable, marginally suitable, not currently suitable for rice land development with values ​​of 20, 39, 28, 13% respectively. Meanwhile, taking into account land use, the very suitable category was 20% and quite suitable was reduced to 33% of the total research area. Based on the available land, the opportunity for developing rice plantations in Paser Regency was relatively large. The study revealed that the SAW approach technique was acceptable for identifying appropriate land for rice development in the study area.

Abstract

Landslides have occurred in several tropical regions of Indonesia and caused many losses in both upstream and downstream areas. This study aims to identify landslide prone areas in the Wadaslintang catchment area, Central Java Province Indonesia. Nine parameters were used to analyze landslide potential such as land use, land slope, rainfall, constituent rocks, soil type, soil permeability, population density, drainage density and runoff coefficient. Each parameter has five possibility scores ​​(1 to 5) determined based on certain criteria. The value of each parameter was presented in a raster map with 15 meters of resolution and analyzed in ArcGIS 10.8. The level of landslide susceptibility was classified into five categories.  The relationship between landslides and the triggered factor was analyzed using Frequency Ratio (FR). The result showed that the parameters with the highest FR values were land use, land slope, rainfall, and soil permeability, indicating a strong influence on landslides. Very high vulnerability areas were found in mixed farmland and settlements especially on steep slopes. Area with moderate and low categories of landslide vulnerability covers the largest area of the study site with an occupied area of 98.54 km2 (51.04% of the total area) and 57.91 km2 (29.99% of the total area), respectively. While the others i.e., areas with the very low, high and very high categories, occupy around of 3.74 km2 (1.94% of the total area), 30.94 km2 (16.02% of the total area), and 1.93 km2 (1% of the total area) respectively. Validation results indicated that landslides mostly occurred in areas with medium and high categories of landslide vulnerability.

Abstract

The East Kalimantan Provincial Government has designated North Penajam Paser Regency as one of rice food supports for the National Capital City (IKN) of the Archipelago. This decision is based the domestic production which met and even exceeded demand in 2020. One step to support rice production is to identify land with the greatest potential for cultivation. Therefore, this study aimed to analyze land suitability zonation for rice production using the criteria of climate, topography, and soil properties, as well as infrastructure. Land suitability was evaluated using simple additive weighting (SAW), multicriteria, and GIS methods taking into account the factors of drainage, soil depth, texture, type, rainfall, temperature, slope, distance from road, distance from river, and land use land cover. Suitability zonation (classes) were arranged based on land suitability classification outlined by the Food and Agriculture Organization (FAO, 1976) in Minister of Agriculture Regulation No. 79 of 2013, namely Very Suitable (S1), Moderately Suitable (S2), Marginally Suitable (S3), Not Suitable (N1). The results showed that the areas classified as highly, moderately, marginally, and not suitable were 4,960 ha (3.1%), 103,738 ha (65.5%), 44,889 ha (28.4%), and 4,708 ha (3.0 %) respectively.Received:2024-02-01 Revised:2024-09-26 Accepted:2025-03-11 Published: 2025-04-27

Abstract

Sumber daya air merupakan elemen penting dalam proses produksi padi khususnya di wilayah tropis seperti Indonesia. Penelitian ini bertujuan untuk menganalisis water supply demand index (WSDI) untuk mendukung produksi padi di Daerah Aliran Sungai (DAS) Serayu Hilir, Jawa Tengah. Evaluasi WSDI didasarkan pada perbandingan ketersediaan dan kebutuhan air di wilayah DAS. Analisis ketersediaan air di DAS dilakukan dengan menggunakan model hidrologi tank, sedangkan kebutuhan air irigasi padi ditentukan dengan menggunakan metode Penman-Monteith dengan bantuan software CROPWAT 8.0. Pada proses perhitungan ditetapkan debit andalan 80% sebagai nilai yang mewakili ketersediaan air minimum untuk memenuhi kebutuhan air irigasi tanaman padi. Berdasarkan hasil analisis, WSDI untuk musim tanam pertama (MT1) dan kedua (MT2) diklasifikasikan sebagai “sangat baik”, tetapi musim tanam ketiga (MT3) mengalami ketersediaan air dengan kategori “buruk”, terutama pada tahun 2018, 2019, dan 2020. Hal ini mengindikasikan bahwa terdapat banyak variasi musiman terkait ketersediaan air yang sangat dipengaruhi oleh pola curah hujan. Studi ini merekomendasikan pola tanam padi-padi-hortikultura untuk memaksimalkan penggunaan air, terutama pada MT3 ketika risiko kekeringan meningkat. Analisis WSDI memberikan informasi yang berguna untuk eksplorasi spasial dan terestrial serta menyoroti pentingnya strategi konservasi dalam mengatasi kekeringan di musim kemarau. Pemilihan tanaman hortikutura pada MT3 didasarkan pada kebutuhan air rata-rata tanaman yang lebih rendah, masa tanam singkat, Penelitian ini berkontribusi pada pengembangan strategi pengelolaan sumber daya air yang berguna untuk meningkatkan produksi beras di wilayah DAS yang mengalami perubahan iklim dan tata guna lahan.

Abstract

Land conversion in river basins poses a threat to future water availability. This research aims to estimate water availability, particularly stream flow for planning of water conservation. Water availability was analyzed using a hydrology tank model. The model was calibrated by using stream flow data measured in a reservoir and then used to estimate water availability in the reservoir's catchment area. The value of model parameters such as wet infiltration coefficient (WIC), dry infiltration coefficient (DIC), soil moisture capacity (SMC), initial soil moisture (ISM), initial groundwater storage (IGWS), groundwater recession constant (k) was determined through the calibration process. The results showed that the model has good accuracy for stream flow calculation indicated by the value of statistical parameters i.e. coefficient of correlation (R) = 0.93, a volume of error (VE) = 0.04, and a coefficient of efficiency (CE) = 1.00. During the wet season, the specific maximum discharge is 0.11 m3s–1km–2. Meanwhile, the minimum specific discharge is 0.030 m3s–1km–2. These differences indicate that optimizing rainwater harvesting during the wet season is required. Rainfall-runoff modeling reveals the potential for surface runoff during the wet season is 1,139 mm. This finding provides an essential reference for water conservation, especially using water recharge ponds. Keywords: Hydrology tank model, Stream flow, Tropical river basin, Water availability, Water conservation.
