Abstract

Ultisol has a texture with a high clay content and a medium to high bulk density so it is susceptible to increasing soil compaction. High soil compaction indicates physical soil problems and inhibits plant growth. The application of soil amendments such as biochar and mycorrhiza can help be help improve soil compaction and support corn growth. This study aimed to examine the potential of biochar from palm fronds and mycorrhiza in improving Ultisol compaction and increasing corn yield. The research was conducted by using a randomized factorial design with 2 factors. The first factor was, oil palm frond biochar with 3 levels, no biochar (B0), biochar 5 tons.ha-1 (B5), and biochar 10 tons.ha-1 (B10). The second factor was mycorrhiza with 3 doses, without mycorrhiza (M0), mycorrhiza 10 grams (M10), and mycorrhiza 20 grams (M20). The results showed that the combination of oil palm frond biochar and mycorrhiza did not show an interaction in improving soil density, but had a significant effect on organic matter, plant height, and yield of maize plants. The application of biochar and mycorrhiza alone was able to improve the bulk density, soil porosity, penetration resistance and soil moisture content. The combination of 10 tons.ha-1 biochar and 20 grams mycorrhiza increased soil organic matter, plant height, and corn yield 66.74%, 24.77%, and 30.26%, repectively compared to the control. Thus, the combined application of oil palm frond biochar at 10 tons.ha-1 and mycorrhiza at 20 grams has the potential to improve soil organic matter content and increase corn yield.

Abstract

Indonesia's national sugar demand continues to increase, while domestic production is still limited due to the lack of accurate data on the area and type of sugarcane cultivation. To address this issue, this research utilized the Random Forest (RF) algorithm on PlanetScope satellite imagery to classify the types of sugarcane cultivation, i.e. early planted sugarcane and pressed sugarcane. This study offers a more detailed approach than previous studies by dividing sugarcane based on its growth cycle into two main classes: < 3 times and ≥ 3 times. The results showed that the Random Forest (RF) method was able to increase the mapping accuracy to 94.52%, higher than conventional methods which are generally in the range of 85-91%. Of the three classification schemes tested, Scheme 3 produced the best performance with an accuracy of 94.52% and a Kappa coefficient of 43.87%. The mapping results also revealed that sugarcane cultivation of ≥ 3 squeezes dominated the study area with 93.08% coverage of the total sugarcane land, while sugarcane of < 3 squeezes only covered 7.55%. The difference between the classification results and the field data shows that the imbalance in the number of samples and spectral similarity between classes are the main challenges in mapping sugarcane cultivation. This finding proves that the Random Forest algorithm with PlanetScope images can significantly improve the accuracy of sugarcane cultivation type mapping compared to previous methods. The results of this study make an important contribution in providing more accurate spatial data to support sugarcane production estimation, optimization of plantation management, and strategic planning in achieving national sugar self-sufficiency.

Abstract

Land Use and Land Cover (LULC) change are major factors affecting Land Surface Temperature (LST), especially in areas experiencing urbanisation and climate change pressures. Ciputri Village, which is predominantly agricultural, has experienced significant changes in land cover patterns over the past two decades, with the potential for increased surface temperature due to land use change. This study analyses and predicts the dynamics of land use and cover changes and their relationship with land surface temperature in the period 2005-2035 using a combination of remote sensing data and Cellular Automata-Artificial Neural Network (CA-ANN) models. The analysis showed that between 2005 and 2020, the area of dense vegetation decreased by 20.49%, while built-up land increased by 43.75%. In line with these changes, surface temperature increased by 1.96°C on average. Predictions to 2035 show a similar trend, with built-up land projected to increase by 20.11%, while average surface temperature is expected to increase by 2.71°C compared to 2005. The correlation between land cover change and surface temperature variation suggests that conversion of dense vegetation to mixed land and built-up land is a major factor driving temperature increases. These findings emphasise the urgency of spatially-based climate change mitigation, including vegetation conservation and sustainable development planning to reduce the impact of future temperature increases.

Abstract

The background of this research is the high level of heavy metal contamination of lead (Pb) and cadmium (Cd) at the former Final Disposal Site (TPA) Talang Gulo, Jambi Province. Preliminary results showed that the concentration of Pb reached 615 mg/kg and Cd was 5.145 mg/kg, exceeding the safe limits set by the Indonesian Ministry of Environment and Forestry Regulation Number 2 of 2023 concerning Soil Quality Standards, which are 300 mg/kg for Pb and 3 mg/kg for Cd. Sansevieria trifasciata laurentii can be used as a phytoremediation agent to address this contamination issue. The objectives of this study were (a) to analyze changes in the concentrations of heavy metals Pb and Cd before and after the phytoremediation process, and (b) to evaluate the effectiveness of Sansevieria trifasciata laurentii in reducing heavy metal concentrations in soil contaminated by landfill leachate at TPA Lama Talang Gulo, Jambi. The results showed that over 8 weeks of observation, Sansevieria trifasciata laurentii effectively reduced the concentrations of Pb and Cd. The plant was able to absorb Pb by 61-91% and Cd by 52-83%. Based on the results of the T-test, a significance value of > 0.05 (0.080) was obtained, with a t_calculated value of 7.867 and a t_table value of 63.1875. Since the t_calculated value was greater than the t_table value, the null hypothesis (H0) was rejected and the alternative hypothesis (H1) was accepted, indicating a significant difference in heavy metal reduction before and after phytoremediation. This research confirms that Sansevieria trifasciata laurentii is effective in reducing the concentration of Pb and Cd in the soil at TPA Lama Talang Gulo, Jambi. This plant has the ability to accumulate heavy metals, making it a potential natural solution for remediating contaminated soil.

Abstract

Conversion of forests into agricultural land is one of the environmental problems currently being faced, leading to various environmental challenges including the decline in soil health. One effort to improve land management and slow down land degradation is to plant various types of trees and intercrops through an agroforestry system. Agroforestry is considered a viable strategy to gradually create a conducive microclimate for soil biota that can improve the physical, chemical and biological properties of the soil. The biomass of microorganisms as quantified – Microbial Biomass Nitrogen (MBN) and Microbial Biomass Carbon (MBC) – has been proposed as sensitive indicator of soil change. This research aimed to understand how MBN responds to agroforestation of Imperata grasslands in Solok Regency, West Sumatra (Indonesia). Fields of eight land use types (in three replications each) were sampled in the Juli-August 2024 period. Plot characteristics such as canopy cover were measured, to compare with MBN and MBC for soil at a depth of 0-10 cm. The results showed statistically significant differences in MBN and MBC in various land uses,  that match differences in canopy cover and age of agroforestry systems. A 1% increase in canopy cover could increase soil MBN levels with 0.94 mg kg-1 (R2 = 0.90). The C:N ratio for microbial biomass varied in the 2-6 range, with the lowest values for intensively cropped land, and the highest for existing or recently converted Imperata grasslands.

Abstract

The spread of Imperata cylindrica in agricultural lands is often associated with a decline in soil fertility, causing crops to be outcompeted by Imperata cylindrica. This study aimed to evaluate land cover, litter biomass, and soil infiltration rates in lands previously occupied by Imperata cylindrica that had been reclaimed with coffee-based agroforestry in Nagari Sirukam, Solok Regency, West Sumatra. The survey on volcanic soils was conducted in July-August 2024. The results showed that natural remnant forests (HT) had the highest canopy cover at 69%, while multistrata  agroforestry (AFMT) had a canopy cover of 37%. The highest standing litter was found in multistrata agroforestry (3.1 Mg ha-1), while at HT had 0.6 Mg ha-1 only. The highest infiltration rate was found in Imperata cylindrica grassland (AF0) with 0.072 cm sec-1, due to the dense rhizomes, while multistrata agroforestry had an infiltration rate that was 73% lower (averaged 0.02 cm sec-1). Although the infiltration rate was lower, agroforestry combined with fire control was effective in maintaining soil stability, reducing erosion, and improving soil quality sustainably, providing long-term benefits for soil and water conservation.

Abstract

Shifting cultivation is a traditional agricultural practice that has been carried out by Indigenous communities across tropical regions for thousands of years. Although this system is characterized by land rotation and slash-and-burn techniques, it has become a subject of debate in the context of sustainable food security and environmental threats. This study aimed to analyze the controversy surrounding shifting cultivation as a potential solution for sustainable food security, as well as its ecological and socio-economic impacts. The method employed in this research was a Systematic Literature Review (SLR). The findings indicated that shifting cultivation had dualistic impacts. On one hand, it could lead to deforestation and significant carbon emissions, particularly when fallow periods were less than ten years, resulting in the loss of up to 80% of forest carbon stocks. On the other hand, when practiced with long fallow cycles (15–30 years), shifting cultivation could support the regeneration of natural ecosystems and restore up to 50% of forest carbon reserves. Furthermore, shifting cultivation contributed to the food security of Indigenous peoples through crop diversification and the preservation of local ecological knowledge in biodiversity conservation. Shifting cultivation represented an adaptive strategy for Indigenous communities in managing natural resources. As a food production system, it held sustainability potential when aligned with natural cycles and grounded in traditional knowledge. Its environmental impact largely depended on the manner of implementation, damaging when mismanaged, but regenerative when properly applied. Therefore, context-specific and inclusive policies that recognize Indigenous land rights are essential to ensure the positive contribution of shifting cultivation to food security and environmental sustainability.

Abstract

The purpose of this study was to determine the NPK value, biomass increase, and pH as the effect of the use of variations in Chinese cabbage and papaya waste feed to reduce environmental pollution and also increase the benefits of organic waste, and organic vegetable and fruit waste has the potential to fertilize the soil. This study was conducted on July 22, 2024 to August 19, 2024 at the Sumber Belajar Ilmu Hayati Ruyani (Bengkulu) and used the RAL (Complete Randomized Design) research method. Data analysis was carried out using an analytical balance, pH paper, and NPK level testing carried out at the Soil Science Laboratory, University of Bengkulu on November 18, 2024 using the methods, namely Nitrogen (Kjeldahl or spectrophotometric method), Phosphorus (Sulfuric acid method followed by spectrophotometric method), Potassium (Extraction method followed by analysis using spectrophotometry). The results of the study showed that the highest NPK levels in sequence were Nitrogen (N) 2.05% in the 100% (Chinese cabbage) feed variation, Phosphorus (P) 0.58% in the 75% (papaya): 25% (Chinese cabbage) feed variation and potassium (K) 0.40% in the 50% (Chinese cabbage): 50% (papaya) feed variation. The highest biomass increase was obtained in the 100% (papaya) feed variation with a weight increase of 27.4g and the highest pH in the 100% (papaya) variation of 6.8 in the normal category. Based on the results of data analysis, it can be concluded that the addition of earthworms Lumbricus rubellus in making vermicompost can degrade Chinese cabbage and papaya waste into usable products, and the use of Chinese cabbage and papaya waste as feed in making vermicompost can increase NPK levels, Biomass and soil pH.

Abstract

Oil palm productivity can be increased by optimizing the availability of nutrients in the soil. Evaluation of nutrient status can be done to determine the level of nutrient availability for plants and as a basis for compiling site-specific fertilizer recommendations. This study aimed to evaluate the soil nutrient status in oil palm plantations at SMK PPN Sembawa Banyuasin and to compile fertilizer dose recommendations according to plant nutrient needs and nutrient availability in the soil. Analysis of chemical and physical properties of the soil was carried out at the Analytical Laboratory of PT. Binasawit Makmur Palembang. The parameters observed were pH, C-Organic, N, P, K, CEC, Al-dd and Soil Texture. This study used a detailed survey method on an area of 5 ha. Soil sampling was carried out at 5 observation points at a depth of 0-30 cm. The results of the study showed that the soil nutrient status at the research location had acidic soil pH conditions, low organic carbon, very low to low availability of N, P, K nutrients and low soil CEC. The soil texture class at the study location was Dusty Clay Loam. The low availability of nutrients at the study location caused the production of oil palm plants to be less than optimal. The calculation of the recommended fertilizer dose for 14-year-old oil palm plants at the study location was, with an average of 225.75 kg of Urea/ha/year or 1.83 kg/tree/year, SP-36 as much as kg/ha/year or 1.42 kg/tree/year, and KCl as much as 226.65 kg/ha/year or 1.83 kg/tree/year.

Abstract

Biochar is an organic soil amendment that can be used as a coating in the production of slow-release fertilizers. This study aimed to determine the growth and yield response of corn in sandy soil due to the application of biochar-coated urea fertilizer, exploring the novelty of using coatings derived from local agricultural waste (which has been understudied) and the effectiveness of fertilizer dosage. The experiment was arranged in a Non-Factorial Completely Randomized Design (CRD) with 6 treatments, which were: P0, P1, P2, P3, P4, dan P5. Data were analyzed using ANOVA at 5%, followed by Duncan’s Multiple Range Test (DMRT) at 5% to determine the best treatment. The results showed that biochar-coated urea significantly influenced plant height during the advanced growth phase (42-84 DAP) but not in the early phase (14-28 DAP). For leaf number, treatments had significant effects at 42, 70, and 84 DAP, with P0 consistently yielding the lowest values. Leaf area also increased significantly at 42-84 DAP, with P3 showing the highest trend. The generative phase (flowering and cob development) was significantly affected by treatments. Meanwhile, corn production under P5 matched the results of P1. Implicatively, corn cob biochar-coated urea has the potential to replace conventional urea with a 20% lower dosage without compromising productivity, thereby reducing production costs and environmental pollution risks due to N leaching. These findings highlight opportunities to utilize corn cob waste as an eco-friendly material in slow-release fertilizer production.
