Abstract

Ultisols generally have low soil fertility status due to their acidic nature, low organic matter, and limited nutrient availability. The utilization of ultisols for oil palm plantations and secondary forests certainly affects the availability of nutrients, organic matter, and soil acidity. Soil management that does not align with the fertility conditions will result in other problems that can threaten the sustainability of agricultural production. The lack of comprehensive research on soil fertility, particularly in Pak Bulu Village, Anjongan Sub-District, limits the available information on the long-term impacts that could affect soil quality. This situation highlights the importance of conducting this research to determine the appropriate land management practices for soil fertility in each land use. This study employed a soil survey method, with sampling points determined by overlaying maps of soil types, slope classes, and land use, using a purposive sampling method, which was divided into four land units. The soil samples were analyzed for their chemical properties in the Soil Chemistry and Fertility Laboratory of the Faculty of Agriculture, Tanjungpura University. The laboratory results were then categorized based on the criteria for evaluating soil chemical properties by the Soil Research Center (1983), and the soil fertility status was subsequently evaluated based on the soil fertility evaluation guidelines by the Soil Research Center Bogor (1995). The evaluation results showed that the soil fertility status of both land uses was at the same level; however, the oil palm plantation had limiting factors such as Cation Exchange Capacity (CEC), Base Saturation (BS), Total Phosphorus (P-total), and Total Potassium (K-total) that were classified as low to very low, while the secondary forest only had Base Saturation and Total Potassium classified as very low, with CEC classified as low.

Abstract

A rice field land-use map is essential in the sustainable land management of rice fields for physical monitoring and planning. Such maps are usually created using multitemporal image data with a spectral approach, but this method can only be applied to certain areas and cannot be easily applied to other areas with different land characteristics. While multitemporal data has been widely used by researchers and proven effective, using single-date imagery can be more efficient. This study aimed to map rice field land-use based on a single-date Sentinel-2 imagery and landform maps. These landform maps were derived through visual interpretation of false colour composite bands, DEMNAS, and land system map. The interpretation resulted in eleven landform classes. The landscape ecology approach assumed the influence of landforms on land-use. The use of ten optical bands in multispectral classification using the maximum likelihood algorithm and convolutional neural network algorithm resulted in twelve land cover classes. The land cover map and the landform map were implemented through a two-dimensional ecological spatial relationship matrix that produced nine land-use classes. The convolutional neural network algorithm obtained an overall accuracy of 90,28% with a Kappa of 0,87. This result was better than the maximum likelihood algorithm, which obtained an overall accuracy of 86,81% with Kappa 0,83. The land-use map for the rice field class produced by the convolutional neural network algorithm had a total area of 33.686,69 ha and a mean absolute error (MAE) value of 0,0241, while the maximum likelihood algorithm produced a total area of 29.590,21 ha with a larger MAE value of 0,0343.

Abstract

Waste is one of the materials that can pollute the river. Most waste is disposed of into the river so that it will cause pollution in the river. The problem of river pollution, one of which occurs in the Loji River located in Pekalongan City, which still discharges a lot of batik waste carelessly into rivers and waterways. The research was conducted in Loji River, Pekalongan City. The purpose of this study was to determine the water quality and level of water pollution in the Loji River Pekalongan due to batik industry waste. The determination of location used survey method. The sampling method was purposive sampling based on land use activities and ease of access to water collection, which was divided into three segments, namely segment I, segment II, segment III. In each segment, two sample points were taken. Water quality was determined based on Government Regulation Number 22 of 2021 according to river water quality standards. The level of water pollution was determined by the Pollution Index (IP) method. The results showed that based on the parameters that had been tested, the water quality of the Loji River no longer met the class II water quality standards. The level of water pollution in Loji River was categorized as lightly polluted based on the pollution index. The lowest Loji River water pollution index value was 0.731 which was in the good category and the highest value was 1.725 which was in the lightly polluted category.

Abstract

Soil respiration and microbial biomass are key biological indicators for soil fertility, especially in the context of agricultural sustainability. Potatoes (Solanum tuberosum L.) are a high-demand crop; their cropping system often ignores conservation principles, causing land degradation. Applying biogeotextiles and probiotics might be potential solution to reduce erosion and maintain soil fertility. This study aimed to evaluate the impact of biogeotextile and probiotic applications on soil respiration and microbial biomass as indicators of soil health in potato farming in Andisols. Randomized Block Design Factorial was used with biogeotextile application as the first factor and and probiotic as the second factor. Four treatments were applied, i.e., control (no treatment), biogeotextile, probiotic, and a combination of biogeotextile and probiotic. Soil pH, % organic C, % N-total, and soil microbial Carbon were measured in 0, 40, and 80 days after treatment (dat), while soil respiration were observed every week. The results showed that the application of biogeotextiles and probiotics had no significant effect on soil pH, soil organic C, and soil N-Total. Microbial biomass remained stable until 80 dat, however, it tended to increase in the final growth phase, irrespective to the effect of biogeotextile and probiotic applications. Soil respiration showed a fluctuating pattern, with a significant increase on 35 and 42 day after planting. This study emphasizes the need for long-term observations to further understand the impact of biogeotextile and probiotic applications on soil biochemical properties in Andisols.

Abstract

This study investigated the potential of anaerobic digestion sludge derived from palm oil mill effluent (POME) to enhance the structure of sandy soils in the Samas Coastal Area, Bantul Regency, Yogyakarta. Sandy soils, having low water retention and nutrient-holding capacity, present significant challenges for sustainable agriculture. By applying different volumes of digestate (0 ml, 50 ml, 100 ml, 200 ml, 400 ml, and 800 ml per kilogram of soil) in a 30-day greenhouse experiment, this research assessed the impact of POME sludge on soil structure improvements, particularly focusing on aggregation, porosity, and bulk density. Treatments with higher digestate volumes, especially 800 ml/kg, yielded substantial improvements in soil aggregation, contributing to better moisture retention. Enhanced aggregation facilitated improved water retention and root penetration, indicating that anaerobic digestion sludge could effectively amend sandy soil limitations. These findings underscore the potential of POME-derived organic amendments as sustainable soil conditioners, offering a dual benefit of waste valorization and enhanced agricultural productivity for marginal soils in coastal areas.

Abstract

The Important Ecosystem Area of ​​Mesangat Suwi Wetlands has a total area of ​​around 14,722.69 ha located in East Kutai Regency, East Kalimantan. These wetlands have a strategic role as a regulators of the upstream water system, a source of freshwater fisheries, and a habitat for important protected animals. This study aimed to determine the rate of suspended sediment transport and river water quality. The study was conducted in two stages, the first was data and sample collection in the field, and the second was laboratory testing. The results of the study showed that the river water discharge and TSS in the Suwi and Masangat Rivers at the study location were directly proportional to the height of suspended sediment. The total average of suspended sediment in Suwi was smaller, it's 0.79 tons/year compared to Masangat at 2.64 tons/year. suspended sediment grains could settle and become bottom sediment. The rate of sedimentation in the river would accelerate the shallowing process which affected the wetlands ecosystem. The reduction in vegetated or forested areas in the Masangat wetlands was due to high human activity compared to Suwi. Currently, the water quality in the study areas, including COD, BOD, TDS, and TSS, is generally still below the standard quality threshold and is categorized as class two, namely water that can be used for freshwater fish farming, recreational facilities, livestock farming, and can be used to irrigate crops or rice fields.

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

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.
