Abstract

This study aimed to explore the characteristics of Arbuscular Mycorrhizal Fungi (AMF) across varying land slope gradients in the conservation area of local pineapple plantations in Majene Regency. The analysis was conducted on five slope categories: flat (0-8%), gentle (8-15%), moderately steep (15-25%), steep (25-45%), and very steep (>45%), to examine the spore density and morphology of AMF as well as to see its relationship to ecological factors such as climate and topography. The results revealed that slope gradients significantly influenced AMF spore density, with the highest density observed on moderately steep and steep slopes. In contrast, lower densities were recorded on flat, gentle, and very steep slopes. Four AMF spore genera were identified: Glomus, Acaulospora, Gigaspora, and Scutellospora. Glomus was dominant across all slopes, Acaulospora was more prevalent on moderate slopes, and Gigaspora preferred steep slopes. Scutellospora was detected in limited quantities on extreme slopes. Environmental factors, including stable temperatures (27.61 °C-27.77 °C), high relative humidity (79.44%-80.41%), and varying precipitation levels, influenced AMF spore distribution and morphology. These findings emphasize the critical role of topography and climate in supporting AMF sustainability in management strategies to conserve AMF biodiversity and enhance crop productivity.

Abstract

weet corn productivity in Indonesia is still in the low category. One of the causes is the problem of soil with low pH. Soil with a low pH causes the availability of nutrients to decrease, thereby inhibiting plant growth and development. Efforts can be made to add dolomite, because hydrolyzed dolomite can increase nutrient availability in the soil. Therefore, this research was carried out with the aim of analyzing the effect of adding various doses of dolomite on soil chemical properties, plant uptake of Ca, Mg and P, population of phosphate solubilizing bacteria, and sweet corn productivity in the Tegalan Land of Junrejo Village, Batu City, East Java. The research design used a randomized block design (RAK) consisting of 9 treatments with 3 replications. Treatment consisted of: M0 = control; M1 = 100% N, P, K; M2 = 100% N,P,K + 100% Kieserite; M3 = 100% N,P,K + 50% Dolomit; M4 = 100%  N,P,K + 100% Dolomit; M5 = 100%  N,P,K + 150% Dolomit; M6 = 75%  N,P,K + 50% Dolomit; M7 = 75%  N,P,K + 100% Dolomit; M8 = 75%  N,P,K + 150% Dolomit. The data was analyzed for diversity using R studio software and continued with the DMRT (Duncan Multiple Range Test) test at 5% level. Next, to see the relationship and influence between parameters, correlation and regression tests were carried out. The findings demonstrated that adding 2.8 tonnes of dolomite per hectare might raise soil CEC (50.61%) and pH (13.41%). In addition, the addition of 4.2 tons/ha of dolomite was able to decrease soil P-available (5.65%), increase Ca-dd (26.4%), Mg-dd (85%), Ca absorption (165.12%), Mg absorption (366.67%), P absorption (78.57%), and sweet corn yield (78.04%). The addition of different doses of dolomite did not significantly alter the overall population parameter of phosphate-solubilizing bacteria. Furthermore, the link between sweet corn yield and nutritional absorption was both robust and weak. The increase in sweet corn output was impacted by P, Ca, and Mg absorption by 54.54%, 41.21%, and 42.79%, respectively.

Abstract

Sweet corn production in Batu city is lower than in other districts/cities. This is thought to be due to a decrease in land area and deterioration of land conditions.  In addition, intensive agricultural practices in the long term can reduce soil pH which will have an impact on the low availability of essential nutrients such as Mg, S, and P. Kieserite fertilizer application can be used as an effort to overcome these problems. This study aimed to evaluate the application of various doses of kieserite fertilizer combined with a single inorganic fertilizer on the efficiency of nutrient uptake and production of sweet corn plants. The research was conducted in Junrejo Village, Batu City in September 2023 - May 2024. The research used Randomized Group Design (RGD) with Kieserite fertilizer doses (0; 26.92; 53.85; 80.77 kg ha-1). The parameters observed and analyzed were plant height and number of leaves, corn production (quantity and quality), soil chemical properties (pH, Mg-dd, SO42-, P-available), nutrient uptake efficiency (Mg, S, P), and phosphate solubilizing bacteria (BPF) population. The research data were analyzed by ANOVA then DMRT further test at 5% level, correlation and regression tests using R-Studio. The results showed that the application of Kieserite fertilizer at a dose of 50% (~26.92 Mg ha-1) combined with inorganic fertilizer (N,P,K) at a dose of 75% shown in treatment A6 significantly increased the efficiency of Mg nutrient uptake by (RE=7.7%), S nutrient by (RE=2.9%), and P nutrient by (RE=49.9%). This increase in nutrient uptake efficiency certainly affected the level of sweet corn productivity. The correlation test between nutrient uptake efficiency (Mg, S, and P) and sweet corn production showed a positive and strong relationship (r=0.5-0.7), where the higher the nutrient uptake efficiency, the higher the sweet corn production. This study confirms the importance of efficient use of Kieserite fertilizer in order to get optimum production results.

Abstract

The range between boron deficiency and toxicity in plants is utterly narrow, so that the certain dose of boron fertilizer is required for plants. Indicators of optimum boron fertilization can be measured from plant production and boron use efficiency (BUE) value. BUE influenced by the amount of soluble B-soil, type of B fertilizer, amount of boron input, type of plant, and adequacy of available macronutrients (NPK). However, excessive application of NPK base fertilizer from inorganic fertilizers can trigger soil degradation. Currently, there has not been much research that measures the reduction in the dose of NPK base fertilizer combined with boron fertilizer on plant BUE. The combination of reducing the dose of NPK base fertilizer and boron fertilizer was tested on sweet corn plants on production and BUE. This study was conducted with a randomized block design with 7 treatments, namely without fertilization (K0), base fertilization (D1), 100% base fertilization and 50–15% borate (D2–D4), and 75% base fertilization and 50–15% borate (D5–D7). The results of the initial soil analysis showed low boron content in the soil, so borate fertilization was required to provide nutrients for sweet corn plants. Application of NPK base fertilizer (100%) and addition of borate fertilizer at a dose of 50-100% (~3-6 kg/ha) significantly increased growth, plant biomass, B uptake, boron recovery efficiency (BRE), and B fertilizer efficiency ratio, compared to lower NPK-base fertilizer. Based on the estimated response curve, the recommended dose to achieve optimum-maximum sweet corn production and maximum boron recovery efficiency is 100% macro inorganic fertilization (urea, SP-36, KCl) combined with 5.72-6.75 kg/ha borate fertilizer.

Abstract

Coffee agroforestry systems have great potential in optimizing the dual function of carbon and biodiversity conservation, especially in areas with high land use pressure. However, although coffee agroforestry has been widely practiced in Indonesia, the specific relationship pattern between carbon stocks and vegetation biodiversity is still not well understood. This study aimed to evaluate (1) the role of coffee agroforestry in maintaining vegetation diversity and carbon sequestration compared to disturbed forests (HT) and (2) the relationship between carbon stocks and biodiversity at various plant growth stages. Three land use systems were  selected such as HT and complex (AFM) and simple (AFS) coffee-based agroforestry systems. The number of trees, species richness (R), Shannon-wiener index (H’), species evenness (E), and carbon stocks were measured in 12 plots (100 m x 20 m) for each vegetation growth stages (seedlings, saplings, poles, and trees). The results showed that the H index in coffee agroforestry was generally low to moderate (0.57-2.05), with the highest diversity in the tree category. The diversity level of AFM could mimic HT. In terms of carbon stock, HT had the highest stock (82±19 Mg ha-1), while total carbon stock showed a positive relationship with H index in all vegetation stages (R2=0,13-0,57). In contrast, the relationship between soil carbon stock and H index tended to be weak (R2=0,10). This study emphasizes the importance of maintaining total carbon stock through diverse vegetation in agroforestri systems to support climate change mitigation and biodiversity conservation.

Abstract

Mangrove forests can store four times more carbon than other tropical forests, mainly stored in the soil. This study aimed to evaluate the carbon content stored at two sediment depths (0-30 cm and 30-60 cm) with different vegetation density levels (very dense, medium, and sparse). The method used was a survey with purposive sampling and sampling using a 7.6 cm diameter PVC sediment corer. Parameters analysed included sediment texture, weight volume (BV), pH, salinity, and organic carbon content. The results showed that the denser the vegetation, the higher the stored carbon and the highest in the 30-60 cm depth zone, with a value of 184-403 tons/ha, while in the upper zone, 0-30 cm amounted to 29-210 tons/ha. In general, higher mangrove density levels had higher salinity, lower BV, but varying pH values with a range of neutral-slightly alkaline, and had a finer soil texture. The highest and lowest densities had salinities of (2.10-4.13 mS/cm) and (0.28-2.50 mS/cm), respectively, with BV values of 0.932 and 1.752 g/cm³.

Abstract

Improving the quality of compost paper is important to increase the availability of nutrients and reduce heavy metals. The quality of compost paper can be improved by using Pseudomonas aeruginosa bacteria, which can help mineralize nutrients and break down or convert heavy metals into less harmful forms. This study used a completely randomized design with five treatments in different concentrations of Pseudomonas aeruginosa bacteria (10%, 15%, 20%, and 25%). The analysis parameters used were pH H2O, Total N, organic C, C:N, Pb and Hg in the resulting compost. The results showed that the KK3 treatment produced higher pH H2O and Total N than other treatments. The availability of Pb metal on KK3 produced a relatively smaller value compared to other treatments, likewise, although it was not significantly different from C. The correlation results showed no significant relationship (p>0.05) between increasing doses of Pseudomonas aeruginosa and the availability of nutrients and heavy metals. The mineralization and incubation processes were factors in the study of improving the quality of compost by using Pseudomonas aeruginosa.

Abstract

The standard values of quality and quantity of living needs continue to increase over time, leading to competition in the utilization of agricultural and non-agricultural land. This results in uncontrolled land use conversion. Land use changes in Gunungkidul between the 1940s and 1970s caused widespread deforestation, making the area barren. Conservation efforts up to the early 2000s yielded positive results. However, population growth and the expansion of activity centers in Gunungkidul during the 2000s may trigger further deforestation. This study analyzes spatiotemporal land use changes in Gunungkidul Regency over the period 2015–2023. Land use data were obtained from Landsat and Sentinel-2 satellite imagery and analyzed using Geographic Information Systems (GIS) and accuracy assessment through ground checks. The results show significant land use changes, particularly the conversion of vegetation into built-up areas, with an increase/decrease in area from 2015 to 2023 of 72.65%. The most significant changes occurred in Wates District, the administrative center of Gunungkidul Regency, forming a pattern concentrated around service centers and spreading linearly along access routes to these centers. Land changes were also observed in the northern and southern regions with a scattered pattern. These changes are driven by population growth and regional development in Gunungkidul Regency. Land use changes may lead to land degradation, highlighting the importance of this study in providing crucial information for better spatial planning and land management in the future.

Abstract

Erosion and sedimentation are two significant issues influenced by hydrodynamic activities and sediment transport, leading to many hydrological changes in a watershed. Erosion in a watershed streamflow will cause sedimentation and riverbed shallowing. A similar situation occurs in the Mentaya Watershed, where sedimentation has triggered a rise in river water levels, increasing the potential for flooding during rainfall events. The RUSLE method in assessing erosion rates provides results that can inform effective erosion control strategies under the current conditions of the Mentaya Watershed. This study aimed to identify the current conditions of the Mentaya Watershed and monitor the estimated magnitude of erosion and sedimentation through RUSLE calculations using Google Earth Engine (GEE). The study results showed a dynamic increase in erosion rates in the Mentaya Watershed from 2016 to 2024, with the highest predicted figure reaching 509.84 tons/ha/year in 2024. The highest amount of transported sediment was found in 2024, occurring in areas with slopes greater than 40%, while the lowest transported sediment was found in areas with moderate slopes of 10-20%. The sedimentation level in the Mentaya Watershed was expected to continue increasing in line with the high erosion rates. This condition will significantly affect the levels of erosion and sedimentation vulnerability in the Mentaya Watershed.

Abstract

Land evaluation is the process of assessing the potential of land for various types of use to support planning and management, taking into account the physical and chemical characteristics of the soil. Seed Agung Village, located in the Muting District, has the potential for development for robusta coffee. This research aimed to determine the actual land suitability class for robusta coffee plants in Seed Agung Village, Muting District. The method used in this study was a survey conducted on 2 land types, namely mix gardens and fields. Soil samples were taken to a depth of 0-80 cm, which is the layer of soil that can still be penetrated by roots. Data were collected through direct observation, laboratory analysis, and data processing. Data analysis was conducted by matching the results of field observations and laboratory tests with land suitability criteria for robusta coffee plants based on the Technical Guidelines for Land Evaluation for Agricultural Commodities (Revised Edition 2011). The results showed that the mix gardens and field/field were classified in the marginal suitability class (S3), with limiting factors in the form of water availability (wa) and nutrients (na). The practical implication of the results of this study is as a basis for land management planning, namely irrigation management and water conservation and soil fertility improvement through fertilization.
