Abstract
The deep-water Sadewa Field is located about 45 km east-northeast offshore of the Mahakam delta, North Kutai Basin, East Kalimantan Indonesia, at water depths of 1,000 to 2,800 feet. Most of the producing reservoirs in Mahakam delta were the Early Miocene sand reservoirs deposited in shallow water of shelf delta. During Miocene the study area was submerged under shallow sea level and there were multiple small-scale low-stand system-tracts deltas deposited along the Sadewa shelf slope. The coarse-grain clastic sediments were fed the shelf slope onto the channels and local fans of the deltas. The local fans were filled with thicker, cleaner, and more porous sands as they had bigger accommodation space and higher depositional energy than the channels. Seismic stratigraphy analysis, guided by seismic attributes, identifies and maps the channel and fan facies. This research focuses on delineating the Sadewa Miocene net-pay sand reservoirs using seismic attributes and inversion. The post-stack AI inversion is applied to mapping the associated lithology, porosity, and pore fluids. The net-pay sand was calculated based on the stratigraphic thickness between the two top target zones (gross sand) with cut-off values of VCL < 40%, POR > 10%, and SW < 70% for each target reservoir. Based on the cross plot between seismic attributes and net-pay thickness, shows that net-pay thickness is associated with high RMS seismic amplitude and low attribute variance. The result shows that RMS seismic amplitude is related to the presence of hydrocarbon fluid and the variance is related to the facies and reservoir geometry in terms of continuity and reflector alignment. Thus, using the RMS amplitude*1/Variance attribute can provide answers for hydrocarbon production needs and determine which geometry and sediment are more prioritized. Later, this attribute can be used to see the distribution of net-pay sand with facies and reservoir geometries with high thicknesses.

Abstract
One of the challenges faced in exploration field development is many geological factors that are still not well understood regarding reservoir distribution and net pay. Fasies analysis become the key to understanding the characteristics of reservoirs and their distribution. This paper discusses the characterize of the reservoirs through stratigraphy and facies analysis supported by seismic attributes. Biostratigraphy data is used to understand the depositional environment and dividing sequence. Each sequence contains a target reservoir with different facies, caused by different sedimentation rates. The target reservoir was found in the Low-stand System Tract (LST), with the gamma-ray log showing fining upward and some coarsening upward patterns. Based on seismic attributes analysis on different sequences, the facies of the target reservoir are slope-fan and channel with slope-fan facies is thicker than the target with channel facies. The thicker slope-fan contains higher net-pay sand that becomes the main target of reservoir. The slope fan and channel facies appear in parasequence that have higher sedimentation rates, while channel facies only appear in parasequence with lower sedimentation rates. Sedimentation rates play a significant role to determine the thickness and the facies of the reservoir.

Abstract
Nickel reserves in the Hukurila area are laterite nickel deposits from the weathering ultramafic rocks. The layers in laterite nickel deposits show different percentages of element values, where the focus point is the saprolite and limonite zones with a large percentage of nickel elements. This research examines the structure of nickel laterite deposits below the surface. Each layer in laterite nickel deposits has a different resistivity value, this means that the structure of the limonite and saprolite layers below the surface can be studied easily using the electrical resistivity tomography method, this method can describe differences in resistivity values below the surface so that the distribution of resistivity values in each layer of laterite nickel deposits in the Hukurila area can be determined. The Wenner-Schlumberger configuration has a good level of resolution vertically and can describe subsurface conditions well laterally which is used in this research. After conducting research, it was found that the resistivity value for each limonite and saprolite layer was 0 – 100 Ωm for the limonite layer and 100 – 400 Ωm for the saprolite layer. And the volume for the two layers is: 165,589.5 m3 for the limonite layer and 124,076.5 m3 for the saprolite layer, volumetric calculations estimate both layers have nickel reserves of 16,956,313 tons for the limonite layer and 14,516,951 tons for the saprolite layer. This geophysical approach highlights the utility of ERT in mineral exploration, particularly in mapping nickel resources critical for sustainable energy solutions.

Abstract
The epicenter of the 2021 swarm earthquake was previously determined automatically using the STA/LTA method. Although, the results obtained show that the distribution of earthquake epicenters still needs to be accurate. This is shown by errors in determining the arrival times of P and S waves. Therefore, in this study, we try to improve the location of the earthquake epicenter manually. This manual detection method is done by re-analyzing the arrival times of P and S waves, which are recorded at each station, one by one. This study aims to determine the pattern of the 2021 Toba swarm earthquake to be used as a preliminary study, mainly in seismic hazard mitigation in Toba. The processing step starts by selecting the P and S arrival times using XQUAKE and then localized using HYPO71. We selected and only used earthquakes with azimuth angles ≤ 200 degrees and a minimum distance from the earthquake to the station < 100 km. The final results show that the epicenter distribution of the Toba swarm earthquake is clustered on the west side of Samosir Island toward the northwest-southeast and not along the Sumatra Fault. The results of this study indicate that the 2021 Toba swarm earthquakes are suspected to be caused by an unidentified geological structure.

Abstract
The Sunda Strait lies between two distinct tectonic regions with perpendicular and oblique subduction in Java and Sumatra, respectively. The region experiences significant seismic activity, with an active volcanic ring resulting from the collision between the Indo-Australian and Eurasian plates. In this research, we employed 3-D velocity tomography to visualize the subsurface in the western Java region, particularly within the Sunda Strait, down to a depth of 150 km. We utilized traveltime data for P- and S-waves from 1,418 earthquakes with at least 15 phases and magnitude greater than M3, which were recorded at 52 the Indonesian Agency for Meteorology, Climatology, and Geophysics (BMKG) seismic stations between April 2009 and December 2021. We used the SIMULPS12 code to simultaneously invert the velocities of P- and S- waves, the Vp/Vs ratio, and the hypocenter locations. High- and low-velocity anomalies from seismic tomography may depict geological features such as the subduction slab, volcanism, and other seismogenic zones. Our results show that high-velocity anomalies indicate the curvature of the oceanic slab subducted below the region extending from Western Java to Southern Sumatra, a low Vp/Vs ratio, and clustered seismicity down to 150 km depths. We suggest the presence of partial melting zones at 100 km depth beneath Mount Sekincau, Krakatau, Prakasak, and the Mount Salak and Guntur complexes, which are indicated by low velocity and high Vp/Vs ratio.

Abstract
Sumatra, Indonesia, is situated in a highly seismically active region. The Sumatra Fault Zone, which spans 1,900 kilometers, runs along the island’s spine and develops within or around active volcanic arcs. The area of interest is located at the boundary between the Indo-Australian and Eurasian tectonic plates, resulting in high pressure and increasing the risk of earthquakes. The Sumatra Fault Segment Renun is characterized by a strike-slip type fault with a west-northwest to southeast orientation in the northern part of the island. This study aims to identify variations in the principal stress direction with depth in the subduction zone, the Sumatra Fault Segment Renun, and transition zone between two structures mentioned. The study used earthquake data from 1977 to 2023, which contains 72 events with focal mechanisms dominated by strike-slip. The earthquakes’ depths were categorized into three groups: 10-40 km, 41-60 km, and 61-100 km. Iterative joint inversion method was applied to determine the rotation of stress that occurred by utilizing data on focal mechanisms to estimate stress within the Earth’s crust. The results included a principal stress diagram with P/T (Pressure/Tension) axis, confidence level of principal stress, Mohr circle, and shape ratio. The principal stress direction (σ1) and shape ratio for the three depth categories are: north-south with a ratio of 0.4-0.55, southwest with a ratio of 0.7-0.9, and west-northwest to southeast with a ratio of 0-0.38. This suggests that the orientation of principal stress in Sumatra Fault Segment Renun is predominantly north-south at shallow depths of 10-40 km, which is positively correlated with the Sumatra Fault and indicates that this stress drives the movement of the Sumatra Fault Segment Renun with a west-northwest to southeast orientation.

Abstract
Yogyakarta is a city rich in culture and heritage, which makes it the second tourist destination in Indonesia. The tangible heritage is well maintained, but the intangible aspects still need to be fully addressed. One of the intangible aspects of Yogyakarta is the sound environment. A preliminary study showed that Yogyakarta’s sound environment is now filled with traffic noise, which largely masks the local soundmark. An appropriate sound environment will contextually develop heritage and cultural sites into more memorable tourism yet a healthy and comfortable environment. The study reported here aims to describe how residents and visitors experience the sound environment in Yogyakarta. A modest quantitative method for collecting data using an online questionnaire was employed, with 252 respondents expressing their opinions. The results show that demographic variables influence respondents’ perceptions of sound. Age variations significantly affect the perception of pleasantness and annoyance. Female participants tend to perceive the sound environment more positively than males. Residents tend to perceive the sound environment as generally appropriate, but visitors perceive it as primarily appropriate. The finding will serve as a reference for further soundscape development of Yogyakarta.

Published: February 2025

Abstract
Climate sensitive urban design is an important design approach to respond to a climate condition in an urban area which has an increasing temperature phenomenon. Temperature rise in an urban area will lead to urban heat island phenomenon which has an impact on outdoor thermal comfort. The proposed central business district master plan in Semarang has a high intensity of floor area ratio (FAR), thus it is at risk to encounter urban heat island. A design review with a climate sensitive urban design approach is needed to cope with the circumstance, anticipate microclimate issues and to achieve an outdoor thermal comfort condition within the master plan.
The aim of this research is to carry out a design review with a climate sensitive urban design approach to assess the central business district master plan and ensure an outdoor thermal comfort condition. Design review uses an ex-ante evaluation time orientation. Ex-ante evaluation is an assessment of a program before it is implemented. This study is calculating numerical variables of microclimate such as air temperature, wind speed, relative humidity, and mean radiant temperature with ENVI-Met software to understand the outdoor thermal comfort based on the thermal comfort index which is PMV and PET.
Micro Changes
Authors: Bruskin Signe 
Published: February 2025

Abstract
Micro changes are defined in a process perspective as fluid, pervasive, ever changing, and existing in the organization’s micro processes. These organizational changes should be addressed in the literature and practice but have typically been neglected or forgotten. However, employees point at micro changes influencing everyday work activities as the most radical ones, crucial to their well-being and engagement at work. This book unpacks micro changes from a process perspective combined with empirical examples and cases. It aims to answer the questions of what micro changes are, why they are crucial to organizations, and how they are to be handled. Thus, it gives scholars within organizational studies new insights into organizational changes grounded in empirical material and inspires practitioners by offering a new and alternative lens through which to view organizational changes.
Physical Changes

Published: February 2025

Abstract
Physical changes are types of micro changes often experienced by employees as radical. This could be moving to another office or shifting to activity-based working. Employees attribute symbolic meaning to the physical space. When employees experience physical changes as radical, it creates an insecurity that goes beyond the practicalities often ascribed to the changes. A shift in new ways of working has made physical changes even more pertinent. This chapter unpacks examples of physical changes and appeals to proactively discussing rules and agreements on working flexibly, remotely, hybrid, at home, and so forth to overcome the challenges and gain from the benefits that arise.
Sententialism
Authors: Salje Léa 
Published: February 2025

Abstract
Chapter 2 considers an inflationist view of articulatory self-knowledge that construes the complete and determinate thought posited at the outset of the process as a linguistically formatted thought. This view is called sententialism. I first identify the core commitments of the view by applying it to an example, and then demonstrate how a worked-out version of the view might go by considering a recent account of self-knowledge by Alex Byrne. Despite a number of starting advantages, I end the chapter by arguing that there are two significant problems for sententialism that should send us looking elsewhere for a satisfying account of our target phenomenon: sententialism is unexplanatory, and it implies an implausible range of stopping points for the process we are interested in. It also invites a corollary view about the format of thought that many will find unappealing.
Reflections and Conclusions

Abstract
This chapter examines the factors that may shape the future of the AIIB, as it navigates its unique position as a multilateral development bank created by China, with the participation of all major donor nations except the United States and Japan. While the AIIB may be deeply nested as a member of the MDB community, this does not mean it is impossible for it to be thrown off track. The chapter examines three different scenarios for the future of the AIIB. Understanding the AIIB in a larger context of a fragmented authoritarian country’s strategies, policies, activities, and actions helps academics and policymakers better grasp important nuances necessary to understand more broadly and clearly how global economic governance is shaped and may evolve.

Abstract
Breathing meditation typically consists of directing attention toward breathing and redirecting attention when the mind wanders. As yet, we do not have a full understanding of the neural mechanisms of breath attention, in particular, how large-scale network interactions may be different between breath attention and rest and how these interactions may be modulated during periods of on-task and off-task attention to the breath. One promising approach may be examining fMRI measures including static connectivity between brain regions as well as dynamic, time-varying brain states. In this study, we analyzed static and dynamic functional connectivity in 72 adolescents during a breath-counting task (BCT), leveraging physiological respiration data to detect objective on-task and off-task periods. During the BCT relative to rest, we identified increases in static connectivity within attention-direction and orienting networks and anticorrelations between attention networks and the DMN. Dynamic connectivity analysis revealed four distinct brain states, including a DMN-anticorrelated brain state, proportionally more present during the BCT than the rest. We found there were distinct brain state markers of (i) breathing tasks vs rest and (ii) momentary on-task vs off-task attention within the BCT, yet in this analysis, no identifiable brain states reflecting between-individual behavioral variability.

Abstract

Aims
While the exacerbating effect of physical exercise and its correlation with arrhythmic outcomes have been demonstrated for Arrhythmogenic Right Ventricular Cardiomyopathy, the impact of physical exercise on other forms of cardiomyopathies is poorly characterized. This study aimed to investigate the relationship between lifelong exercise intensity and the development of cardiac manifestations in subjects carrying a Likely Pathogenic (LP) or Pathogenic (P) truncating variant of titin (TTNtv).

Methods
TTNtv carriers – patients and family members – were interviewed regarding their exercise habits from birth until diagnosis (type of activity, hours/week, weeks/months, months/years, and number of years of exercise). Those engaging in ≥4 hours of vigorous exercise per week (equivalent to ≥1440 METs×minutes/week) for a minimum of 6 years were classified as Athletes. All others were classified as Non-athletes.
The correlation between vigorous physical activity and the development of left ventricular systolic dysfunction (LVSD), defined as left ventricular ejection fraction below 45% (LVEF &lt;45%), was explored. Additionally, secondary endpoints included the occurrence of life-threatening ventricular arrhythmias (LTA - i.e., aborted cardiac arrest due to hyperkinetic arrhythmias, documented sustained ventricular tachycardia – SVT –, or appropriate implantable cardioverter-defibrillator therapy), non-LTA ventricular arrhythmias (i.e., &gt;1000 premature ventricular complexes/24h and/or non-sustained ventricular tachycardia – NSVT), and the development of atrial fibrillation and/or atrial flutter (AF/AFL) during follow-up.

Results
Among the 117 subjects (73% male, median age 45 – IQR 35-57 years), 38 (32%) were Athletes. Vigorous exercise was not associated with the development of LVEF &lt;45% (adjusted OR 0.663, 95%CI 0.261-1.685, p 0.388), nor with the occurrence of LTA (p = 0.607), non-LTA (p = 0.648), and supraventricular arrhythmias (p = 0.701). Comparable results were obtained when considering the total amount of METs x hours/life burned by subjects as a continuous variable.

Conclusion
In carriers of TTNtv, vigorous physical activity was not associated with LVSD and LTA development.
Temporal fruit microbiome and immunity dynamics in post-harvest apple (Malus x domestica)

Published: February 2025

Abstract
The plant immune response plays a central role in maintaining a well-balanced and healthy microbiome for plant health. However, insights on how the fruit immune response and the fruit microbiome influence fruit health after harvest are limited. We investigated the temporal dynamics of the fruit microbiota and host defense gene expression patterns during post-harvest storage of apple fruits at room temperature. Our results demonstrate a temporal dynamic shift in both bacterial and fungal community composition during post-harvest storage that coincides with a steep-decline in host defense response gene expression associated with pattern-triggered immunity. We observed the gradual appearance of putative pathogenic/spoilage microbes belonging to genera Alternaria (fungi) and Gluconobacter and Acetobacter (bacteria) at the expense of Sporobolomyces and other genera, which have been suggested to be beneficial for plant hosts. Moreover, artificial induction of pattern-triggered immunity in apple fruit with the flg22 peptide delayed the onset of fruit rot caused by the fungal pathogen Penicillium expansum. Our results suggest that the fruit immune response helps to orchestrate a microbiome and that the collapse of the immunity results in the proliferation of spoilage microbes and fruit rot. These findings hold implications for the development of strategies to increase fruit quality and prolong shelf life in fruits and vegetables.
