Abstract

Tropical peatlands are among the largest carbon stocks on earth, but also the most vulnerable to anthropogenic disturbances. This study aims to analyze the impacts of land-use change on carbon stocks in peatlands, focusing on conversion to plantations, agriculture, and infrastructure, as well as to evaluate the effectiveness of restoration strategies and protection policies. Using a systematic review approach of 50 recent scientific publications (2010–2025), the results show that peatland conversion causes large amounts of carbon release, ranging from 70–120 tons of CO₂ per hectare per year, accompanied by land subsidence of up to 7 cm per year. Drainage and land fires are the main factors accelerating carbon emissions. In contrast, restoration efforts through rewetting and revegetation have been shown to reduce emissions by up to 65% and increase long-term carbon accumulation. The success of this strategy is greatly influenced by the biophysical conditions of the land, policy support, and local community participation. This study recommends the need for an integrated approach that includes moratoriums, economic incentives, legal strengthening, and technology-based monitoring as strategic steps in protecting carbon stocks and mitigating climate change.

Abstract

The shifting cultivation system is an integral part of the local culture of the Papuan people in Indonesia, persisting to this day. This study investigates the relationship between vegetation abundance and soil chemical composition in former plantation lands of varying ages in Papua, Indonesia. Three sites with distinct fallow periods - 5 years (BK-5), 10 years (BK-10), and 15 years (BK-15) - were analyzed. Multivariate analysis was employed to model the combination of dominant vegetation density and soil physical and chemical characteristics. The results revealed that the BK-5 site exhibited poor soil quality, characterized by acidic pH and low organic carbon and nitrogen content. In contrast, the BK-10 and BK-15 sites demonstrated improved soil fertility. The multivariate analysis highlighted distinct differences in vegetation composition and soil nutrient parameters among the sites, with specific plant species associated with particular soil conditions. The study confirms that older former plantation lands tend to have higher soil fertility, suggesting that short fallow periods may be insufficient for optimal soil fertility restoration. These findings underscore the importance of considering the age of former plantation lands and the role of vegetation in shaping soil conditions. This research provides valuable insights into the ecological recovery of post-agricultural landscapes in Papua.

Abstract

Indramayu Regency is one of the rice barns in Indonesia with high productivity, producing agricultural waste in the form of straw in large quantities. However, the suboptimal management of straw, such as its direct burning in fields, causes environmental pollution and the loss of soil nutrients. On the other hand, the growth of water hyacinth in Indramayu waters causes problems for the aquatic ecosystem. This study investigates how bokashi, made from rice straw and water hyacinth, functions as a bioameliorant to improve rice development and productivity. This study was conducted using a factorial approach in a Randomized Block Design (RBD) with two factors, namely the dose of rice straw bokashi (0, 10, and 20 tons ha-1) and the dose of water hyacinth bokashi (0, 10, and 20 tons ha-1). It is proven that the use of bokashi and water hyacinth as bioameliorants increases rice development and productivity. According to the research results, there was a significant interaction between the two types of bokashi on plant height at 14, 28, 42, and 56 HST, number of leaves at 42 and 56 HST, and weight of 1,000 grains as well as harvest yield. The optimal dose recommended to achieve the best results is 10 tons ha-1 of rice straw bokashi and 20 tons ha-1 of water hyacinth bokashi. The implementation of this technology has the potential to increase agricultural productivity sustainably and reduce negative impacts on the environment through more efficient utilization of agricultural waste and aquatic ecosystems.

Abstract

Inceptisol is a marginal soil type with low fertility, limited water retention, and an acidic pH, which poses challenges for horticultural cultivation, including chaisim (Brassica rapa var. parachinensis). This study aimed to evaluate the effect of biochar dosage on soil physical properties, soil pH, and chaisim growth in Inceptisol from three locations: Singgalang, Padang Lua, and Sariak. Five biochar dosages were used (0, 15, 20, 25, and 30 tons/ ha-1). The observed parameters included water percolation, soil pH, and fresh plant weight. Results showed that the 20 tons/ha-1 dose gave the best results by reducing water percolation by up to 4%, increasing soil pH from 6.38 to 6.42, and producing the highest fresh plant weight of 203 grams per pot, which was much higher than the control (11 grams per pot). The increased soil pH improved the availability of nutrients such as phosphorus, calcium, and magnesium, which are important for plant growth. However, the 30 tons/ ha-1  biochar dose caused soil pore saturation, reducing aeration and nutrient uptake efficiency, resulting in a lower fresh plant weight of 97 grams per pot. Combining biochar with NPK fertilizer also improved water use efficiency and nutrient availability. The effectiveness of biochar was further influenced by initial soil characteristics, with the best results found in soil from Singgalang.This study showed that biochar could be a sustainable soil management strategy to improve horticultural crop productivity on marginal tropical soils.

Abstract

This study was conducted to evaluate the effect of chemical fertilizer coated with biochar on the growth of shallots (Allium ascalonicum L.) in sandy soil. The research was carried out at the Greenhouse of the Agroecotechnology Department, Faculty of Agriculture, Trunojoyo University of Madura, located in Telang Village, Kamal District, Bangkalan Regency, Madura, at an altitude of approximately 5 meters above sea level, from August to December 2023. A non-factorial Completely Randomized Design (CRD) was used, consisting of six treatments: P0 (control), P1 (recommended fertilizer), P2 (80% urea coated with rice husk biochar + bentonite), P3 (100% urea coated with rice husk biochar + bentonite), P4 (80% urea coated with corn cob biochar + bentonite), and P5 (100% urea coated with corn cob biochar + bentonite). The results showed that the application of biochar-coated urea fertilizer had no significant effect on plant growth and yield parameters such as plant height, number of leaves, number of tillers, number of tubers, tuber diameter, and root volume. However, plant height at 42 days after transplanting (DAT), the number of tillers at 42–63 DAT, and chlorophyll content showed significant differences among the treatments. Additionally, soil analysis parameters—including pH, organic carbon (C-organic), and soil nitrogen (N)—showed significant responses to the treatments.

Abstract

Rabbits are animals that have the potential to be cultivated, but the liquid waste they produce can cause pungent odors. The solution is to process the waste into biourine. This study aims to determine the effect of fermentation time and dosages of EM-4 and molasses on the physical and chemical properties of rabbit biourine, and to determine the best treatment. This research was conducted from March to May 2025 in Pandanrejo Village, Bumiaji District, Batu City. This study used a factorial completely randomized design with 2 factors with 3 replications. The treatment consisted of a combination of fermentation time (0, 14, and 28 days) and dosages of EM-4 (0, 20, 40 and 60 mL) and molasses (0, 25, 50 and 75 mL). The results showed that the treatments had a significant effect on color, odor, pH and N-total levels, but no significant effect on phosphorus (P2O5) and potassium (K2O) levels. The best treatment was obtained in the W2D3 treatment, which produced biourine with a dark brown color, a distinctive fermentation odor, pH 4.57, N-total content of 0.158%, phosphorus (P2O5) 0.024% and potassium (K2O) 0.381%.

Abstract

Consumption of sweet corn has increased from 2021 to 2024. To meet the growing market demand, sweet corn production must be carried out in a sustainable, economical, efficient, and environmentally friendly manner. The use of a combination of sludge, rice husk charcoal, compost, and inorganic fertilizer was tested to enhance corn plant growth and productivity. The study was conducted at the Cikabayan Experimental Farm, IPB University, using a Randomized Complete Block Design (RCBD) with five treatment levels and three replications. The results showed that treatment S2H1 (75% sludge + 75% rice husk charcoal + 30% compost + 75% NPK) exhibited the best vegetative and generative growth (stem diameter, number of leaves, ear length, biomass weight per plot, and ear weight per plot). The S1H1 treatment (100% sludge + 75% rice husk charcoal + 30% compost + 75% NPK) showed improved biological and chemical soil quality (pH, organic carbon, total nitrogen, total phosphorus, and base saturation). All treatments resulted in an R/C ratio above 1, indicating economically viable potential. The results indicate demonstrate that the combined use of sludge and organic materials allows NPK fertilizer inputs to be reduced by 25%, supporting sustainable agriculture.

Abstract

This study examines soil mesofauna and macrofauna as bioindicators of soil health and ecological integrity across three land-use systems: oil palm plantations, open lands, and bamboo forests. Land-use change increasingly threatens soil biodiversity and ecosystem functioning in tropical regions, where soil organisms are key to nutrient cycling, aggregation, and ecological resilience. Understanding how land use influences soil faunal communities is crucial for assessing belowground integrity. Despite their critical ecological roles, soil faunal indicators are rarely integrated into soil health assessments in tropical systems. Addressing this gap, this study compares soil mesofauna and macrofauna diversity across contrasting land uses to establish their potential as reliable bioindicators. Soil samples were collected from the surface layer (0–10 cm) using standardized coring under uniform topography, soil type, and climate. Systematic random sampling was applied, with mesofauna extracted using Berlese-Tullgren funnels and macrofauna extracted by manual hand-sorting following the TSBF method. Specimens were identified to the order level. Shannon-Wiener analysis showed that bamboo forests supported the most complex and functionally rich communities (mesofauna H′ = 1.498; macrofauna H′ = 0.309), followed by oil palm plantations and open lands. Acari and Collembola were dominant mesofauna sensitive to habitat quality, while Formicidae and Diplopoda reflected higher trophic and structural roles. Open lands exhibited low diversity and dominance of stress-tolerant taxa, indicating reduced ecological function. The integrated assessment of mesofauna and macrofauna provides a robust framework for evaluating soil health, highlighting vegetation complexity as a driver of nutrient cycling, aggregation, and microbial activity.

Abstract

Paddy field conversion in Maros Regency during the 2013–2023 period reached 1,946 hectares, equivalent to approximately 0.7% per year, and has led to a food balance deficit since 2023. This study aims to optimize the planning of new paddy fields to support food security in Maros Regency through: (1) identification of land availability, (2) land suitability analysis, (3) determining priority allocation areas, and (4) establishing the optimal allocation of new paddy field development. Data on available land were obtained through visual interpretation of Spot 5 Satellite Imagery (2025), field surveys, and spatial analysis. Land suitability analysis for paddy fields was conducted using the criteria of BRMP-SDLP and the Multicriteria Evaluation (MCE) method. Priority allocation was determined using Spatial Multicriteria Decision Making (SMCDM). Optimal allocation was generated using a Goal Programming model with the Weighted Goal Programming (WGP) method. The results show that satellite image interpretation achieved high accuracy, with a Kappa coefficient of 92.0%. A total of 31,922 hectares of land were identified as available for new paddy field development, consisting of 1% highly suitable (S1), 26% moderately suitable (S2), 11% marginally suitable (S3), and 61% not suitable (N), with slope and soil texture as the main constraining factors. Priority areas were divided into Priority 1 (11,761 ha) and Priority 2 (20,161 ha). Simulation of four allocation scenarios (2,500 ha, 5,000 ha, 7,500 ha, and 10,000 ha) indicates that the 10,000-ha scenario yields the smallest goal function value, suggesting a more efficient and balanced distribution of land allocation.

Abstract

Marginal lands such as tidal lands used for agriculture face several problems, including shallow pyrite layers, land affected by seawater intrusion (salinity), high soil acidity (low pH) and nutrient-poor soil. The shallow pyrite layers and salinity in Pemusiran Village are major obstacles to agricultural development and have resulted in decreased land productivity. This research aims to determine and analyze the distribution of pyrite layer depth, Soil Electrical Conductivity (EC) and groundwater in Pemusiran Village. This research uses a survey method, where observation points are determined using the grid method. The results of the study showed that the sulfidic material layer (pyrite) of the soil at the research location was dominated by pyrite depth of 50-100 cm, which was included in the potential acid sulfate soil typology (PASS) category, namely PASS-2 with an area of 1,055.32 ha or 45.73% of the total research area. The depth of the pyrite layer at the research location was influenced by the distance from the sea and rivers, land management and the thickness of the peat layer. The soil EC value at the research location ranged from 64-981 μs cm-1 in the very low category. The highest EC value for groundwater was 8,863 μs cm-1 in the poor category and the lowest value was 355 μs cm-1 in the good category. Generally, the highest EC values for soil and groundwater were in coastal areas and were lower in areas far from the coast and rivers.
