Abstract

South Sumatra Province has characteristics that significantly increase hotspots and produce greenhouse gas (GHG) emissions in strong El Niño phenomena. This study investigates the impact of forest fires on GHG emissions during extreme climate in the South Sumatra Province from 2010 to 2020. This research analyzes the effects of La Niña and El Niño on the region by analyzing factors such as precipitation patterns, temperature fluctuations, hotspots, and greenhouse gas emissions. This study indicates that forest fires mostly happen during the dry season (May to October). El Niño occurred for the second time in 2015-2016 and 2018-2019, which affected the highest fire (hotspots, HSs) during the strong El Niño. Meanwhile, La Niña occurred three times in 2010-2011, 2011-2012, and 2017-2018, which is related to the low HSs found and represents the highest annual rainfall in the last ten years. The highest forest fire (HSs = 17.559) occurs in the characteristics of A1-B4 (precipitation 0-100, SSTA > 0.5°C). The highest GHG emission (>400 Mton) occurred in 2015 when the strong El Niño occurred in South Sumatra Province. The strong and weak El Niño produces the highest GHG emissions of more than 30 megatons per day, while the maximum mean daily GHG emission is under 10 megatons per day. Hotspot numbers rise exponentially with increasing SSTA, showing strong statistical relationships (R² > 0.80, r > 0.79) with burned area (R² = 0.90, r = 0.92) and burned area with CO₂ emissions (R² = 0.77, r = 0.79).

Abstract

Participatory conservation is an activity to mitigate and adapt to forest and land fires through field farmer school (FFS) activity which forest farmer groups (FFG), non-governmental organizations (NGOs), and academics attend. This research aims to provide an innovative approach to conservation activities with the community, especially on Mount Arjuno, which often experiences forest fires. The results show that local stakeholders and authorities must support community participation in forest conservation. This study shows that FFS (Field Farmer School) activities can facilitate the community in identifying problems and generating ideas for conservation activities through the agroforestry system, mitigation and adaptation of forest and land fires, and edu-ecotourism. Conservation designs and community participation strategic plans are outputs of forest fire mitigation and adaptation activities. The FFS as the methodology used is adequate for knowing what the farmer needs relating to conservation that stakeholders will program. Moreover, generating the conservation activity must be combined with activities to increase the FFG income. So, the FFG will have good welfare.

Abstract

Tree management such as pruning of coffee canopy and fertilization in coffee-based agroforestry systems plays a crucial role in reducing nutrient losses through leaching. This study aims to evaluate the impact of coffee pruning and fertilization management on nutrient leaching. The study was conducted in a coffee agroforestry system in the Universitas Brawijaya forest from February to August 2023. This study used a split-split plot design with main plots of coffee canopy pruning (T1: pruned coffee, T2: unpruned coffee), subplots of fertilizer type (O: organic fertilizer, A: inorganic fertilizer, M: 50% organic + 50% inorganic), and sub-plots of fertilizer dosage (D1: dosage based on farmer practice, D2: recommended dosage based on the Coffee and Cocoa Research Center, D3: dosage based on the replacement of nutrients removed by the coffee bean harvest). The study had 18 treatments with 4 replicates, resulting in 72 experimental plots. The variables measured included ammonium, nitrate, phosphorus, and potassium concentrations. Sampling of nutrient leaching was conducted four times over a period of six months (February-July), specifically in February, March, April, and July 2023 at 0.5 m distance from the coffee stem in 0.6 m depth of soil. The results showed that pruning coffee plants had a significant effect (P < 0.05) on nutrient losses due to leaching, especially nitrate and potassium. A pruned coffee canopy in an agroforestry system was able to reduce nitrate and potassium leaching by 30% and 13%, respectively, compared to unpruned coffee in the agroforestry land. Nutrient loss of phosphorus through leaching was found to be 21% greater in treatment D1 compared to D2. However, this study did not find a significant effect of the interaction between pruning and fertilization in reducing the leaching of nitrogen, phosphorus, and potassium nutrients.

Abstract

The presence of groundwater in the groundwater basin increases the potential of rainwater seeping into the soil and reaching the groundwater system. As a result, the soil takes longer to get saturation and maintain its stability. The groundwater basin stability is also influenced by the layer's lithological, soil, and morphological properties above the groundwater system and human activities on the land. The purpose of this study was to characterize the groundwater basins, non-groundwater basins, and landslides that happened in those locations in the tropical region of Bogor, Indonesia. The characteristics of landslide events, including lithological, groundwater table, soil, slope, and land use in each groundwater basin zone, were evaluated using quantitative descriptive analysis. The result showed 686 landslides from 2015 to 2019 that mainly occurred in the discharge zone, characterized by slope classes of >45%, soil types of Technosol (Inceptisols), Quaternary lithology periods, and settlement land use. The landslide type in the groundwater basin is dominated by surface landslides, while the landslides in the non-groundwater basin are mostly shallow landslide types.

Abstract

Bogor, Cianjur, and Sukabumi areas of West Java Province, Indonesia, are vulnerable landslide areas. This study analyzes the landslide characteristic and the factors affecting landslides. The analysis was carried out on 148 landslides from 415 of 2018-2020 landslides, which were selected purposively by considering the heterogeneity of soil, geology, slope classes, land use type, and accessibility of landslide locations. Landslide characteristics and factors affecting landslides were analyzed using frequency analysis and binary logistic regression. The results showed that the most dominant characteristics of surface and shallow landslides were the landslides characterized by slopes >45%, Quaternary geological period, Andisol soil type, agriculture land use type, the occurrence of rain, and absence of earthquake. The dominant factors affecting surface and shallow landslides are human activities in land use, soil properties, steep-very steep slopes, Inceptisol and Entisol soil orders, young rocks (Quaternary geological period), rainfall events, and high earthquake magnitude.

Abstract

Root system mechanical reinforcement through root-soil cohesion on slope stability is important. However, the root cohesion of Tectona grandis, Maesopsis eminii, and shrubs (Chromolaena odorata) on slope stability is rarely studied and modelled. This study aimed to model the mechanical effect of vegetation through root cohesion, namely teak (Tectona grandis), Maesopsis eminii, and shrubs (Chromolaena odorata). The study was conducted in a simultaneous landslide on January 1, 2020, that dominantly occurred on vegetated slopes of Sukajaya District, Bogor Regency, West Java. The Wu model's root cohesion (CR) was modelled on slope stability using a modified Bishop model. The modelling used the data from field and laboratory-measured. The study found that the presence of a root system increases slope stability's factor of safety (FOS). The root system of young Maesopsiss eminii produces the largest effect of FOS compared to the root system of shrubs, teak, and old Maesopsis eminii. The slope stability of vegetated slopes is a function of the CR and the effective root zone depth. The highest total CR of vegetation was teak with 0.398 kPa, followed by shrubs, young Maesopsis eminii, and old Maesopsis eminii with 0.202 kPa, 0.191 kPa, and 0.087 kPa, respectively. The effective root zone of teak, young Maesopsis eminii, and shrub were 500, 230, 140, and 66 cm, respectively.
