Abstract

Climate change has become a significant threat to water resources management in river basins (DAS). This article examines the impacts of climate change on water resources management, with a focus on changes in rainfall patterns, increasing temperatures, and effects on the hydrological cycle. Increased rainfall intensity and global temperatures have changed the characteristics of river discharge, affecting water availability for agriculture, households, and industry. Climate change also affects the hydrological cycle through changes in rainfall patterns, increasing temperatures, and changes in evapotranspiration. Studies have shown that increasing average temperatures and changing rainfall patterns in Indonesia have had significant impacts on water management in watersheds, including the Brantas and Citarum watersheds. In addition, land-use changes such as deforestation and urbanization exacerbate the impacts of climate change, increasing the risk of flooding and drought. Effective water resources management requires a holistic and adaptive approach, such as Integrated Water Resources Management (IWRM), which integrates various sectors and interests in water management. The implementation of IWRM in Indonesia has shown mixed results, with some watersheds successfully adopting this approach, while others face obstacles such as lack of coordination between agencies and limited accurate hydrological data. Innovative and participatory adaptive approaches to water management are needed to address challenges caused by climate change, ensure sustainability of water resources, and maintain ecosystem balance. This article emphasizes the importance of local community involvement and development of climate-resilient water infrastructure in water resource management in the basin

Abstract

Integrated Watershed Management (DAS) is a holistic approach to managing natural resources, reducing disaster risk, and increasing environmental resilience. This study aims to analyze the effectiveness of integrated watershed management in reducing disaster risk in Indonesia. The analysis methods include literature review, policy evaluation, hydrological and environmental data analysis, and participatory studies involving various stakeholders. The results of the analysis indicate that integrated watershed management has a significant role in mitigating natural disasters such as floods, landslides, and droughts. Steps such as vegetation conservation, erosion control, land use regulation, and active community participation have helped reduce disaster risk in a number of watersheds in Indonesia. Several challenges that need to be overcome in the implementation of integrated watershed management include lack of coordination between institutions, limited resources, and low public awareness of the importance of environmental conservation. Therefore, further efforts are needed to improve institutional capacity, strengthen collaboration between institutions, and increase community participation in integrated watershed management. This study provides deeper insight into the role of integrated watershed management in reducing disaster risk in Indonesia, as well as providing recommendations for further improvement and development in disaster mitigation efforts at the watershed level.

Abstract

Inceptisol is a type of soil that has a dominant coarse fraction. Inceptisol has a productivity that is generally still low because it has a coarse texture with low-moderate soil organic matter content, which has a negative impact on soil physical properties and plant growth. This study aims to examine the long-term effect of biochar on N element leaching through the residual effects of rice husk and dolomite biochar. The method used in this study was a Completely Randomized Design with 8 experiments with 3 replications, so that 24 experimental units were obtained. Based on the results of the study, it can be concluded that inceptisol soil if given Biochar + dolomite treatment, makes the soil too porous and causes high N nutrient leaching. giving biochar up to 22 tons + 1.5 tons of dolomite (treatment H) is able to maintain the pH of water from acidic rain.

Abstract

A study on chemical properties of Inceptisols in four slope classes in scrubland areas was conducted in Nagari Aie Dingin, Lembeh Gumanti Sub-District, Solok Regency, from May 2022 to February 2023. This research was aimed to assess the chemical properties of Inceptisols in several slope classes in Nagari Aie Dingin, Lembah Gumanti Sub-District, Solok Regency. The study was carried out using a survey method. Samples were purposively taken from four slope classes (8-15%, 15-25%, 25-45%, >45%) and one comparison land (25-45%) at depths of 0-20 cm and 20-40 cm with three replications. The parameters analyzed were soil pH, organic C, total N, C/N ratio, available P, and CEC. The research results indicated that the soil pH ranged from 4.61 units to 5.62 units (acidic to slightly acidic). The organic carbon content of the soil ranged from 1.51% to 2.55% (low to moderate). The total nitrogen content ranged from 0.05% to 0.19% (very low to low). The C/N ratio ranged from 9.37 to 35.8 (low to very high). The P-available content ranged from 2.29 ppm to 43.6 ppm (very low to very high). Cation exchange capacity (CEC) had values from 14.28 me/100g to 43.62 me/100g (low to very high). The result showed that in the research area there was a decrease in the value of soil chemical properties along with increasing slope class.

Abstract

Fertilization is essential for sustaining crop productivity, yet foliar application of NPK fertilizer remains underutilized in cabbage (Brassica oleracea) cultivation. This study evaluated the effectiveness of liquid inorganic NPK fertilizer applied directly to cabbage leaves to enhance growth and yield. The experiment followed a randomized complete block design (RCBD) with six treatments: no fertilizer (P0), 0.5 dose (P1), 0.75 dose (P2), 1.0 dose (P3), 1.25 dose (P4), and 1.5 dose (P5), alongside a uniform basal application of Urea, KCl, and SP-36. Results showed that the 1.5-dose treatment significantly improved plant height, leaf number, yield per plot, and yield per hectare compared to the control. Economically, this treatment also achieved the highest benefit-cost ratio, indicating superior profitability. These findings suggest that foliar application of liquid inorganic fertilizer is both agronomically effective and economically viable for cabbage production. The recommended application rate is 3.0 L/ha, applied at 2, 3, 4, and 5 weeks after transplanting.

Abstract

Cold lava floods contain volcano material that is rich in micronutrient which will gradually release through weathering process. The study of micronutrient elements affected by cold lava floods was conducted in Nagari Limo Kaum, Tanah Datar Regency, from October to March 2025. This research was aimed to assess and analyze the content of micronutrients (Fe, Mn, Cu, Zn, Mo and B) in land impacted by cold lava floods in Nagari Limo Kaum, Tanah Datar Regency. The study was carried out using a survey method. Soil samples were collected using purposive sampling from lava deposit (Locations 2, 3, and 4), areas affected by floodwater flow without deposition (Location 5), and unaffected areas (Location 1) as a comparison. Soil samples were collected from 0-20 cm soil depth at each location with 3 replicates. The analyzed parameters included soil pH, cation exchange capacity (CEC), exchangeable aluminum, and micronutrients (Fe, Mn, Cu, Zn, Mo and B). The results showed that increased the micronutrient content and exchangeable aluminium, increased while Zn and B content had low to very high criteria. The chemical properties especially pH and CEC of the soil  at L1 and L5, were lower that those at impacted soils.

Abstract

Cabbage (Brassica oleracea L.) is a high-value vegetable crop that requires balanced nutrient management to achieve optimal growth and yield. This study aimed to evaluate the agronomic and economic effectiveness of a compound fertilizer containing 21% N, 17% P₂O₅, and 17% K₂O on cabbage production. The experiment was conducted using a randomized complete block design with seven fertilization treatments, including a control, a reference NPK treatment, and five levels of compound fertilizer (0.5 to 1.5 recommended doses), each replicated four times. Observations included plant height, leaf number, yield per plant, yield per plot, and yield per hectare. Statistical analysis was performed using ANOVA and Duncan’s Multiple Range Test at a 5% significance level, while economic analysis was based on profit and benefit-cost ratio (R/C). The results showed that the 1.0 dose of compound fertilizer significantly improved plant height at 3 and 4 weeks after transplanting, increased leaf number at 5 weeks, and produced the highest yield per plant (1.92 kg), per plot (43.8 kg), and per hectare (17,500 kg). This treatment also demonstrated the highest relative agronomic effectiveness (139%) and economic viability, with an R/C ratio of 2.23 and a profit of IDR 14,487,900. Based on these findings, the recommended application rate for cabbage is 211 kg/ha of compound fertilizer, applied one week after transplanting. The study concludes that compound fertilizer is both agronomically effective and economically profitable for cabbage cultivation under the tested conditions.

Abstract

Sweet corn is a horticultural commodity that is widely cultivated and consumed in Indonesia. This study aimed to determine the growth and yield response of sweet corn plants to the application of various doses of ammonium sulfate fertilizer. The research was conducted at Pasir Kuda Experimental Field, Bogor, West Java. This experiment used a randomized complete block design (RCBD)with a single factor, namely the dose of fertilizer application. Treatments were arranged in 4 levels of application, namely: (1) control, (2) standard NPK fertilization, (3) 0.5 dose of N, (4) 1,0 doses of N, (5) 1,5 doses of N, and (6) 2,0 doses of N. The results of this test indicate that the application level of ammonium sulfate fertilizers at the application level of 1,0 doses N fertilizer treatment can generally provide plant height, stem diameter, number of leaves, stover weight, cob weight with husk, cob weight without husk, production plot-1, and productivity which are statistically higher than the control treatment. The application of 1,0 doses N fertilizer treatment had Relative Agronomic Effectiveness (RAE) values that meet the requirements to pass the fertilizer effectiveness test, with the highest RAE value obtained in the application of 1,0 doses N fertilizer at 188%.
