Abstract

[SPATIAL DISTRIBUTION SOIL CARBON MARAPI MOUNTAIN]. Volcanic activity will significantly affect the carbon component and its fraction in the soil. Volcanic soils have high carbon content. This study aimeds to map the soil carbon and its fraction vocanic soil of Mt. Marapi. A total of 93 soil samples were taken with a grid interval of 750 x 750 m at a depth of 0-20 cm spread across the Southwest, West and Northwest areas affected by the eruption of Mt. Marapi at a radius of 4.5-7 km from the peak. The parameters analyzed were: bulk density, soil pH, C-organic, C fractions. The results showed that, soil pH ranged from 4.59-6.19 (pH H2O) and 3.8-5.8 (pH KCl), C organic ranged from 3.00%-14.16%, C-very labile ranged from 0.001-0.045%, C-labile ranged from 0.14-1.41%, C boundts non-crystalline clay ranged from 0.20-2.10%, C-metal complex ranged from 0.11-1.70%. Soil pH in Northwest was different from those of in West and Southwest. Very labile carbon in Southwest slope was not the same as those found in West and Northwest. C-metal complex in Northwest soil did not the same as those found in West and Southwest. The diversity of carbon fractions can be used as a reference in tillage to maintain carbon storage and become a marker for soil health. Full text pdf

Abstract

[EFFECTS OF WATERLOGGING ON THE GROWTH OF TARO (Colocasia esculenta (L.) Schott) ACCESSIONS IN COASTAL AREA OF BENGKULU]. Taro (Colocasia esculenta (L.) Schott) is a vital tropical root crop with considerable potential for food diversification due to its nutritional and carbohydrate content. In Bengkulu Province, Indonesia—a region with rich taro genetic diversity in coastal agroecosystems—systematic evaluation of local accessions under waterlogging stress remains limited. This study assessed the effects of waterlogging depth and accession variability on taro growth using a Randomized Complete Block Design with three replications, evaluating ten local accessions under three waterlogging levels: 0 cm (control), 15 cm, and 30 cm. Results revealed significant (p < 0.01) differences among accessions for plant height, leaf width, leaf length, and stem diameter, indicating substantial genetic variation. Waterlogging significantly affected leaf width and length (p < 0.01) and plant height (p < 0.05), but not leaf number or stem diameter. No significant accession × waterlogging interaction was observed, suggesting consistent accession performance across treatments. Karang Tinggi (AK10) showed the greatest plant height (134.69 cm) and stem diameter (6.39 cm), while Bentiring 2 (AK4) exhibited the largest leaves. Moderate waterlogging (15 cm) did not impair growth relative to the control, but 30 cm waterlogging reduced leaf dimensions. These findings support the selection of resilient accessions like Karang Tinggi and Bentiring 2 for cultivation in flood-prone coastal areas and provide a foundation for breeding waterlogging-tolerant taro varieties.

Abstract

[RELATIONSHIP BETWEEN SOIL SILICA AND PLANT TISSUE SILICA ACROSS DIFFERENT LAND USES IN MADIUN DISTRIC]. Agricultural land in Madiun District frequently experiences drought during the dry season, reducing plant tolerance to environmental stress. Although not an essential nutrient, silica can enhance plant resistance to drought stress and plays a role in nutrient binding. This study aimed to examine soil and plant tissue silica content across various land uses in Madiun District. The research was conducted on three land use units in  Gunungsari, Banjarsari, and Sirapan Villages. Soil and plant samples were collected at 0–30 cm and 30–60 cm depths. Soil analyses included physical properties (texture and moisture content) and chemical properties (pH,organic C, total N, cation exchange capacity, and silica content). Data were analyzed using correlation and linear regression tests. Results showed that the highest silica content in plant tissue was found in paddy fields (40%) and the lowest in sugarcane fields (29%). Soil silica content in sugarcane fields was highest in Banjarsari Village (57.31%) and lowest in Sirapan Village (56.75%), while in paddy fields it was highest in Gunungsari Village (66.69%) and lowest in Sirapan Village (65.57%). The presence of silica influenced soil cation exchange capacity and nitrogen content, and it contributed to increasing plant tolerance to drought by reducing water loss through transpiration. The study recommends land management practices to enhance silica availability, such as returning crop residues to the soil. Full text pdf

Abstract

[ARTHROPOD DIVERSITY IN RED CHILI CULTIVATION UNDER SUGAR PALM SHADE IN SOUTH SUMATRA]. Arthropods are essential components of terrestrial ecosystems, functioning as pollinators, decomposers, herbivores, and natural enemies, and their presence reflects the health of agricultural landscapes. The red chili agroforestry system under sugar palm shading in South Sumatra creates a favorable habitat for arthropod communities through the interaction of canopy cover, microclimate conditions, and plant diversity. This study aimed to analyze the structure, diversity, and ecological roles of arthropod communities associated with chili plants withinthis system. Sampling was conducted systematically across several plots, and collected specimens were identified and analyzed using the Shannon–Wiener diversity index, evenness, and dominance metrics. The results showed that the arthropod community consisted of various orders, with predators forming the dominant guild, followed by pollinators, herbivores, and decomposers. The balanced distribution of individuals among trophic groups indicates a stable community structure, while fluctuations in population density were associated with plant growth stages and seasonal variation. The agroforestry environment of chili plants shaded by sugar palms supports a functionally diverse arthropod community that contributes to maintaining biodiversity and enhancing natural pest regulation. Arthropods in shaded cultivation also experience a more stable microhabitat than those in open fields, allowing for stronger interspecific interactions, including predator–prey dynamics that aid in natural pest suppression. Sustained diversity suggests that agroforestry systems reduce environmental stress on arthropod populations, helping communities function effectively. Therefore, the findings of this study provide an important scientific foundation for developing sustainable agroforestry management strategies that improve ecosystem services and support resilient agricultural production.

Abstract

[SPATIAL ANALYSIS OF THE IMPACT OF CLIMATE VARIABILITY ON LAND SUITABILITY POTENTIAL FOR BLACK PEPPER (Piper nigrum L.) Cultivation In The Bangka Belitung Islands]. The Bangka Belitung Islands are a major center of pepper production in Indonesia; however, over the past decade, cultivated area and productivity have declined due to climate variability and limited land biophysical information. This study aims to analyze land suitability for pepper (Piper nigrum L.) cultivation based on climatic, topographic, and soil indicators, as well as to evaluate the effect of climate variability on changes in land potential across the island region. The data used include rainfall observations from 71 rain gauges during 2014–2023, ERA5 reanalysis data for surface temperature, humidity, and solar radiation, and maps of slope and soil types as physiographic parameters. All parameters were processed using a Geographic Information System with the Inverse Distance Weighting (IDW) interpolation method to generate the spatial distribution of climate variables, while a weighted overlay method was applied to determine land suitability classes. Validation was conducted by comparing ERA5 data with observational data to ensure the consistency of spatial climate patterns. The results indicate that climate variability contributes to a decline in land suitability in coastal areas with soil textures that are sensitive to environmental changes. Most of the area, covering 1,189.76 ha, is classified as Highly Suitable (S1) and is distributed in central Bangka Island and parts of Belitung Island. Meanwhile, 452.65 ha are classified as Moderately Suitable (S2) and are predominantly located in coastal areas with soil limitations and coastal environmental influences. These findings highlight the importance of climate adaptation strategies to support sustainable national pepper cultivation. Full txt pdf
