Spatial Analysis and Assesment of The Impact of Regional Border Transportation Corridor on Land Use: A Case Study of Yogyakarta-Surakarta Transportation Corridor
Authors: Susilo B , Widianingrum N A 
Published: February 2025

Abstract
Land use change is a complex process that significantly contributes to the increasing greenhouse gas emissions on the earth’s surface. While researchers have traditionally focused on urban areas, the impact of transportation corridors on land use change, affecting 15–20% of the global land, has been overlooked. This study examines the land use and land use change from 2000-2024 in the transportation corridor between Yogyakarta and Surakarta city, utilizing the Yogyakarta - Klaten segment as a case study. The research employs the spatial proximity analysis method to delineate transportation corridors, creating analysis units known as corridor and buffer zones. The findings reveal a change in land use over approximately 24 years, covering an area of 1,373.81 hectares, which is 13.86% of the total research area. The most significant (68.52%) type of land use change observed is the transition from agricultural land to settlement and other buildings. Moreover, the study highlights that the intensity of change tends to diminish with the increasing distance from the central Yogyakarta-Solo road, highlighting the impact of transportation corridors on land use patterns and distribution. Interestingly, the Yogyakarta-Prambanan zone shows a higher intensity of change than the Prambanan-Klaten zone, indicative of the influence of regional characteristics on land use patterns and distribution.

Authors: Harwinanto F D A , Adji T N 
Published: February 2025

Abstract
The increasing population growth rate causes an increase in demand for land and groundwater usage. Limited land in cities means urban development will focus on sub-urban areas within the city area. This research aims to describe changes in groundwater recharge in sub-urban regions of Bantul Regency and analyze urbanization’s effects on groundwater recharge in sub-urban areas of Bantul Regency. The method used in this research is the water budget method which uses rainfall, evapotranspiration, surface runoff, and groundwater recharge as its parameters. Groundwater recharge is obtained through rainfall, evapotranspiration, and surface runoff. The result showed that the groundwater recharge within the study area has decreased due to the increasing surface runoff. Through policies, land use change can be controlled to decrease the impact of surface runoff and keep the quantity and quality of the groundwater at acceptable levels.

The study aims to identify formations with potential as source rocks, based on the geochemical characteristics of source rocks and the burialhistory in the research area. The analysis was conducted on single research well. From the study conducted on one well, source rock samples were obtained from the Mallawa Formation and Balangbaru Formation, which were further analyzedin geochemical analysis. The method employed in this research involves analyzing geochemical characteristics (quantity, quality, and maturity level), including Total Organic Carbon (TOC), Rock Eval-Pyrolisis (REP), Vitrinite Reflectance (VR), Van Krevelen Diagram, HI and Tmax Cross-plot. Burial history is analyzed using Petromod 1D software this software can create burial history graphs used age data, top formation, biostratigraphy (paleo water depth), lithology, and TOC values. From this data, burial history modeling can be generated. The quantitative and qualitative analysis results indicate that the potential source rocks are the Mallawa Formation and Balangbaru Formation, based on the organic material content (total organic carbon). The Mallawa Formation has TOC values ranging from 0.77% to 6.11%, with Fair to Excellent quantities, type III kerogen indicating that this type of kerogen is derived from woody terrestrial material. It is rich in carbon and produces primarily gas when heated, and Immature maturity, while the Balangbaru Formation has TOCvalues ranging from 0.03% to 7.41%, with Fair to Excellent quantities, type II/IIb kerogen is also rich in hydrogen but produces a mix of oil and gas when heated, and Immature to Peak Mature maturity. Based on the research results, it is inferred that source rocks in the Mallawa and Balangbaru Formations have the potential to generate hydrocarbon productssuch as oil and gas. The burial history of the source rocks in Well AYP-1 is controlled by the sedimentation rate, basin subsidence rate, and tectonics.

Published: February 2025

Abstract
Frequently drilling activity causes formation damage. The damage can be estimated from the drill stem test analysis. Formation damage is indicated by a skin factor (S) with higher than 0 or flow efficiency parameter (FE) lower than 100%. Improvement of formation damage can cause an increase in flow rate. Artificial neural network (ANN) model is used to estimate the increase flowrate of productive zones on “X” Field with FE 20% to 100%. The ANN model used reservoir pressure, temperature, permeability, formation thickness, specific gravity of oil, gas to oil ratio, oil viscosity, and flow efficiency as input parameters. While the flow rate is as the output parameter. Based on predictions with the ANN model obtained the increase in flow rate varies between 1.1% to 78.0%. Besides, it is found that flowrate of the layers on the field is influenced by the product of kh, where kh is equivalent with the flowrate.

Published: February 2025

Abstract
Microbial Enhanced Oil Recovery (MEOR) involves injecting nutrients into oil reservoirs to enhance the oil recovery. This technology has the capacity to increase the amount of oil that can be extracted. Microbes in the reservoir oil can be activated by nutrients that they come contact with, leading to a response. The interaction between nutrients and microbes in the reservoir oil can optimize oil recovery efficiency by catalyzing the decomposition of hydrocarbon chains. This research is written based on the information provided. The objective of this study is to evaluate the efficiency of nutrition injection by analyzing data obtained from scientific journals. The aim of this study is to investigate the impact of different injection-production well designs and the most effective nutrient injection rate on enhancing oil recovery and the recovery factor value in the “DHP” Field using MEOR injection. The methodology employed in this study comprises a comprehensive review of existing literature and the utilization of reservoir simulation techniques. This data is subsequently utilized to conduct reservoir simulation for nutrient injection using a simulator. The problem lies in the fact that the scenarios generated only incorporate sensitivity analysis of the injection-production well layouts and injection rates, without taking account into the economic factors. The study’s findings indicate that employing suitable nutrient injection well layouts and optimizing the nutrient injection rate can enhance oil recovery in the MEOR process through nutrient injection. The simulation findings for the Base case, Scenario 1, 2, 3, 4, 5, 6, 7, and 8 yielded oil recovery factors of 12.62%, 15.90%, 13.72%, 24.92%, 23.25%, 26.53%, 25.63%, 15.33%, and 15.90% respectively. Hence, the most optimal approach for enhancing oil recovery in the “DHP” Field by MEOR nutrition injection is Scenario 5, which involves a direct drive injection design and an injection rate of 40 bbl/day.

Published: February 2025

Abstract
This study utilizes computer simulations to explore the potential use of Methyl Ester Sulfonate (MES) surfactants derived from palm oil to enhance oil recovery stability. The main function of MES in reducing interfacial tension (IFT) and boosting recovery factor (RF) includes several key actions. MES molecules align at the oil-water interface, reducing interfacial energy and IFT. It also forms micelles that encapsulate oil, further lowering IFT. By disrupting water’s cohesive forces, MES helps disperse oil droplets, improving fluid dynamics and stabilizing emulsions. These effects enhance oil recovery, making MES effective in enhanced oil recovery applications. Using simulation software, this approach offers a simpler and more flexible way to evaluate different concentration levels, as it can be performed anytime and anywhere without incurring extra expenses typically associated with laboratory setups. It enables researchers to quickly identify the optimal concentration that yields the best recovery factor. Various concentration levels were tested to determine the optimal concentration that yields the best recovery factor. The tested concentrations ranged from 0.50% to 2.03%, with a specific gravity of 41 API for all variations and salinity brine at 8900 ppm. At a concentration of 0.50%, the lowest recovery factor (RF) obtained is 35.62%, while the highest RF is achieved at a concentration of 2.00%, with a value of 55.35%.

Published: February 2025

Abstract
The Kesongo Mud Volcano Complex on Java Island, Indonesia, is a distinctive geological feature that necessitates further study of its land cover to understand potential successions. This research examines the land cover characteristics using satellite imagery to investigate surface and visual features. Employing Harmonized Sentinel-2A MSI imagery analysis, coupled with field observations, we uncovered the complexity of the land cover, including variations in vegetation and substrate characteristics. Remote sensing techniques identified the mud volcano land-cover traits based on the normalized difference vegetation index (NDVI) and normalized difference moisture index (NDMI), both of which exhibited a linear regression trend with a coefficient of determination (R²) of 0.6184. The findings reveal contrasting patterns between the central, inner, and outer rim regions, distinguishable by specific band combinations, notably [B8, B4, B3] and [B11, B8, B12]. Furthermore, moisture and vegetation around the mud volcano indicate characteristics of recently active mudflow areas, particularly where Typhaceae, Cyperaceae, Poaceae, and Euphorbiaceae are present. This study enhances our understanding of the dynamic land cover of this mud volcano complex and provides insights into its geological and ecological features, offering valuable perspectives for geoconservation.

Published: February 2025

Abstract
West coast area of Takalar district is the central government area which is experiencing significant population growth and infrastructure development. The research area is located above alluvium deposit and has natural hazard potential triggered by Walanae Fault, Selayar Fault and Flores Back Arc Thrust Fault, which are the main seismic sources close to research site. Seismic disasters can be caused by several factors including distance, earthquake strength and local site effects. In this research, the authors used Horizontal to Vertical Spectral Ratio (HVSR) microtremor method, by comparing the horizontal to vertical components to obtain shallow factors to describe the local characteristics of research site. Takalar microzonation aims to map areas based on seismic vulnerability in the Quaternary Sediment site in Takalar Regency. The research results show that local conditions of the research site are dominated by soft to very soft soil. Coastal areas have softer characteristics and harder away from the coast. The results of microtremor microzonation show that coastal areas have low dominant frequency. This indicates that the sediment thickness is thicker, make those areas vulnerable to seismic shocks. Meanwhile, the seismic vulnerability index results are dominated by the high category throughout the research site and the amplification factor values are low to high. The authors hope this research can be used as a consideration for relevant stakeholders to mitigate potential of seismic disaster hazards in Takalar Regency.

Published: February 2025

Abstract
PT. Batubara Lahat, located in South Sumatra province, is a company that conducts coal mining using the open pit method. The open pit mining method creates a flow of water that has low pH properties commonly known as acid mine drainage and then becomes one in the lowest area of mining which is commonly called a sump. Acid mine drainage is water produced through oxidation of sulfide minerals in rocks by oxygen in the air in an aqueous environment. In good mining engineering regulations, companies must be responsible for overcoming the potential for the formation of acid mine drainage, one of which is by analyzing the quality of water that will be formed in testing as a first step by understanding the geochemical characterization of rocks on a laboratory scale. Geochemical characterization of rocks is determined by several laboratory tests, namely, static tests and kinetic tests, where in static tests are usually carried out by measuring total sulfur, paste pH, NAG pH, and Acid Base Accounting (ABA) methods, while in kinetic tests are usually carried out by the Free Draining Column Leach Test (FDCLT) method. The samples used in this study were the side rock samples of PT Lahat Coal, namely BL-A1, BL-A2, BL-B, BL-C, BL-D, BL-E and BL-F. Based on the results of this study, samples BL-A1, BL-A2 are categorized as potentially acidic rocks or PAF while samples BL-B, BL-C, BL-D, BL-E and BL-F are categorized as rocks that are not potentially acidic or NAF. The results of characterizing the geochemistry of these rocks can be a consideration for PT. Batubara Lahat in managing rock dumps in order to meet the environmental standards that have been set.
