Abstract

The oil palm land donated to Universitas Samudra is planned for the development of the campus area, including the construction of a number of buildings and supporting facilities. However, the process of identifying and mapping oil palm plants has been done manually, which is time-consuming, inefficient, and prone to errors. This problem underscores the need for faster and more accurate methods to support spatial data-based planning. This study aimed to calculate the number of oil palm plants in 2022 and 2023 at the University of Samudra using the template matching method with eCognition Developer software, as well as evaluate the accuracy of automatic detection results based on aerial images obtained using drones. The research was carried out using survey methods and descriptive analysis, involving primary data in the form of aerial imagery and field validation, as well as secondary data from the map of the oil palm plantation area of Samudra University. The results of the study show that the number of oil palm plants in 2022 based on automatic calculations was 2,060 trees, while the results of manual validation showed the actual number of 2,169 trees with a difference of 109 trees. In 2023, the automatic calculation detected 1,932 trees, while the actual number was 2,030 trees, with a difference of 98 trees. The accuracy level of automatic calculations in 2022 had an average accuracy of 98.56%, recall of 94.05%, and F1-score of 95.63%, higher than in 2023 with precision of 97.41%, recall of 92.73%, and F1-score of 94.98%. Then the template matching method is effectively used for oil palm tree detection and can support the planning of campus area development efficiently. The use of this technology is expected to be a model that can be implemented in various other educational institutions.

Abstract

One of the impacts of the rampant urbanization is the rising phenomenon of Urban Heat Island (UHI). This phenomenon occurs when the temperature in urban areas is higher than in the surrounding areas that are less developed (rural). The research was conducted in DKJ Jakarta Province, namely East Jakarta City, South Jakarta City, North Jakarta City, Central Jakarta City, and West Jakarta City. This study aimed to analyze the highest and lowest distribution of UHI based on the Land Surface Temperature (LST) algorithm and using the overlay method. Data were collected through literature study and analysis of Landsat 8 level 2 satellite imagery collection 2 Tier 1 OLI 2. The results of the study showed that high urbanization (population density) affected the average value of CSI to increase so that it was directly proportional to UHI. The non-UHI intensity range ranged from -4 oC to 0 oC, while the areas experiencing UHI had an intensity range ranging from ±0oC to 8.6oC. The city with the highest intensity was estimated to be in the East Jakarta City area while the lowest was in the Central Jakarta area.

Abstract

The purpose of this study was to find out and describe the use of GIS in mapping the level of landslide vulnerability in Sibolangit District, Deli Serdang Regency, North Sumatra. The model used referred to the estimation of the 2004 Puslittanak, as it utilizes parameters that are easy to measure, widely available, and in accordance with the territory of Indonesia. These parameters include rainfall, rock type, soil type, slope gradient, and land cover.  The research methods used were overlay, scoring, and weighting. In the mapping process, each parameter had a score of classification multiplied by the weight of each parameter, then the results of the multiplication of the scores and weights were summed based on the suitability of their geographical location. The results of the study showed that the Sibolangit District area had the potential for landslides from low, medium to high levels. Based on the landslide disaster prediction model, the study area predominantly fell under the moderate susceptibility class, covering 15 villages. Additionally, 10 villages were identified with low vulnerability level and 5 villages with high vulnerability level. The use of GIS was also used to see the size of each area in Sibolangit District based on the level of vulnerability to landslide disasters. The level of validity of this map is quite good because it uses official data and methods suitable for the territory of Indonesia. Thus, it is accurate enough for the purpose of vulnerability identification and landslide disaster mitigation planning.

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.
