Authors: Srikandi Nadhira , Hapsari Handayani Hepi , Andiek Maulana Mahendra 
Published: December 2024

Abstract
Floods in urban areas are primarily caused by high rainfall combined with inadequate drainage systems, inappropriate land use changes, and insufficient flood mitigation measures. Surabaya, characterized as a seasonal zone with periodic rainfall, frequently experiences flood inundation due to the loss of water retention areas and an inadequate drainage infrastructure. Three-dimensional (3D) city models provide a detailed representation of urban environments, capturing the three-dimensional geometry of objects and general urban structures. This 3D modeling approach can enhance the understanding of flood depths impacting surrounding buildings and infrastructure and assist in estimating the effects on drainage capacity and catchment areas for long-term planning. In this research, 3D flood inundation modeling was conducted using LiDAR data and aerial photography, integrated with other GIS data. The flood inundation simulation was performed using HEC-RAS, while the 3D modeling was carried out using GIS-based software employing semi-automatic methods. The results of the 3D modeling and visualization indicate potential flood inundation depths reaching up to 5 meters, affecting 1,100 buildings and 30 roads. Further research could focus on improving the accuracy of terrain and channel data used in flood modeling to enhance the precision of the results.

Abstract
Geospatial information has various beneficial to support sustainable environment and human health, such as monitoring distribution of pollutant gases. Carbon Monoxide (CO) is one of harmful pollutant gases. So, preventing the increases of CO and its wider spreading in the atmosphere is very important and also can be as an initial step to mitigate the CO increases. It is often the case that CO concentrations in many big cities are higher than those in its surrounding cities. The current study was conducted in Surabaya city, which is known as one of the major big cities in Indonesia and pose high population density and urban activities. Sentinel-5P imageries were used as the primary data processed and analysed using Google Earth Engine (GEE) platform in order to estimates CO concentration and its distribution in Surabaya. WebGIS for CO monitoring was developed using GEE as the final output in this research. This allowing the results of CO concentration and distribution to be accessed by public. Temporal of Sentinel-5P imagery starting from 2018 up to present were used as the primary data for extracting the CO in Surabaya. The WebGIS developed in this study can be seen at https://ee-devikarahma28.projects.earthengine.app/view/co-distribution-of-surabaya-city. Based on the WebGIS that describes the CO distribution in Surabaya, this study showed the highest CO concentration was in 2018, with values range from 0.294 to 0.331mol/m2. While the lowest CO was in year 2022 with values ranges from 0.0261 to 0.0298 mol/m2. The highest CO concentration has frequently occurred in the central of Surabaya, while the lowest CO concentration was in the east Surabaya.

Published: December 2024

Abstract
Carbon monoxide is a colorless, odorless, and poisonous gas. For several decades, industry contribute as the main factor of the increases of carbon monoxide in the atmosphere. Bekasi has the largest number of industries in West Java and has continuously an increasing trend. This will contribute to the increases of carbon monoxide concentration in the city. This study analyzes the spatial increases in carbon monoxide concentration due to industrial growth in Bekasi city and its vicinity from 2019 to 2022. The carbon monoxide time series data were obtained from Sentinel-5P satellite imagery, downloaded and processed using Google Earth Engine. The analysis reveals that the carbon monoxide concentration in Bekasi ranges from approximately 0.037 mol/m2 to 0.041 mol/m2. District-level analyses indicate that Tarumajaya consistently exhibited high CO levels, reaching 0.044 mol/m2 in 2020. Furthermore, the results show a moderate correlation of 0.688 between industrial growth and carbon monoxide concentration, indicating that as the number of industries increases, CO levels in Bekasi rise accordingly. Additionally, this study examines the influence of wind direction on the spatial distribution of carbon monoxide, highlighting that winds from specific directions can transport CO to areas farther from its source, resulting in variable concentration levels across the region.

Published: December 2024

Abstract
Urban parks are green oases in the middle of the hustle and bustle of the urban, where people can do activities and socialize. Not only are they beautiful, but urban parks are also designed to facilitate various activities, such as recreation and sports. The aim of this research is to determine the distribution of active urban parks based on service coverage in Semarang. So, it will be able to provide guidance to users when visiting urban parks. The research scope area is Semarang, which observations objects focuses on 51 active urban parks. This research is a continuation of previous research. In this research, the results of mapping the range of active urban park services in Semarang were obtained using a buffer process, so this research uses the results of this mapping. Analysis was carried out to ensure all houses in Semarang had active park visit directions. This is done because there are still houses that are not included in the scope of the visiting directions. Generally, the results describe that the distribution of active parks in Semarang is not completely even. There are districts which have various directions choices for visiting active urban parks, they are Semarang Selatan District, Semarang Timur District, and Semarang District. However, there are still districts that do not have park to visit, specifically Tugu District. Therefore, the public is advised to visit the nearest park first to visit.

Published: December 2024

Abstract
In the face of escalating environmental concerns, effective management of air quality remains critical. This study focuses on Perth, Australia, a region impacted by frequent bushfires and industrial emissions, necessitating precise monitoring of atmospheric pollutants like NO2. Leveraging advanced remote sensing technologies, including Sentinel-2 and Sentinel-5P satellites, this research assesses the spatial and temporal dynamics of NO2 before, during, and after the 2021 Wooroloo bushfire. A key objective was to convert satellite-derived NO2 data from mol/m2 to μg/m3 to enable accurate environmental assessment. This conversion utilized a unit conversion method, improving accuracy metrics substantially, with a correlation coefficient (r) increasing from 0.59 to 0.82 and root mean square error (RMSE) decreasing from 7.58 μg/m3 to 3.20 μg/m3. A regression model, validated with ground-level measurements, demonstrates robust predictive capability (R2 = 0.76, RMSE = 2.58 μg/m3), aiding in the creation of NO2 distribution maps across Greater Perth. Comparison with six ground stations revealed varying accuracy (RMSE: 2.9249 to 7.2705 μg/m3), likely influenced by proximity to the fire and prevailing wind directions. Spatiotemporal analysis depicted distinct NO2 patterns: stable levels pre-fire, dramatic increases during, and gradual post-fire recovery. Maximum NO2 concentrations peaked during the fire (up to 79.227 μg/m3), exceeding air quality guidelines. Post-fire, concentrations normalized, yet sporadic peaks persisted, indicating an ongoing environmental impact. Furthermore, analysis of environmental parameters such as Land Surface Temperature (LST), precipitation, and Normalized Difference Vegetation Index (NDVI) during the study period revealed significant correlations with NO2 levels. LST showed a positive correlation (r = 0.64) with NO2 concentrations during the fire, suggesting temperature influences on atmospheric stability and pollutant dispersion. Precipitation exhibited a negative correlation (r = −0.52), indicating its role in scavenging NO2 from the atmosphere post-fire. NDVI displayed a weak negative correlation (r = −0.30), reflecting vegetation recovery trends post-fire. This comprehensive study integrates advanced remote sensing with statistical modelling to enhance air quality monitoring and inform decision-making in bushfire-prone regions. By elucidating NO2 dynamics and their environmental implications, this research contributes essential insights for mitigating air pollution and safeguarding public health amidst climate-induced challenges.

Published: December 2024

Abstract
Illegal fishing activities are the biggest challenge for Indonesia in protecting its territorial waters from illegal fish transhipment. To address this issue, a real-time load measurement system is needed on ships. Real-time measurement devices can also replace land-based measurement functions, thus improving the quality of catch during the transfer of tuna from the ship to the cold storage. The method used in this research is testing, which requires real data to support and simulate the implementation of the study. The research involves a prototype that utilizes a load cell as a sensor for detecting the mass of fish, and NodeMCU as a microcontroller programmed with Arduino IDE language. The prototype is integrated with Wi-Fi to send data to a MySQL database. The sensor circuit consists of four load cells, a junction box, and an HX711 amplifier. The results of the sensor experiment at a 12-degree tilt condition, which indicates the roll or trim condition of the ship, show a decrease in sensor accuracy and relatively unstable results compared to normal conditions. The average accuracy rate of sensor readings under normal conditions is 99.42%, while the average accuracy rate of sensor readings at a 12-degree tilt is 96.98%.

Published: December 2024

Abstract
In the offshore oil industry, well-intervention barges provide crucial support for the production enhancement of offshore platforms. These specially designed ships contain tools and equipment to perform perforation activities that keep the wells active. However, with the relevance and practical operations, operators meet two principal challenges: 1) limited barge availability to serve a set of platforms and 2) each platform exhibits specific job requirements (different number of wells, duration, production gain, cost, time windows). This short literature review provides an overview of the Well Intervention Campaign Problem (WLICP) adopting the model of Vehicle Routing Problem considering Profits (VRPP). We propose four carefully designed questions to answer. It relates to 1) problem structure 2) modelling approach 3) solution technique and 4) optimization scenario. According to the result, WLICP exhibits a rigorous project management structure. Its structure contains the breakdown of n-sub-project representing VRP nodes. Combinatorial optimization helps barges find routes and schedules to maximize profit.

Abstract
Overfishing is caused by excessive fishing, resulting in a significant decrease in fish populations. This has a detrimental impact on marine ecosystems, fish availability, and fishermen’s income. Since 2008, the fishing area in the Madura Strait has experienced overfishing. In relation to the many fishing areas in Indonesia that have experienced overfishing, Government Regulation No. 11 of 2023 was issued on controlled and proportional fishing, carried out in measured fishing zones, based on fishing quotas to preserve fish resources and their environment, and equalize national economic growth. From the perspective of a Marine Engineer, one method to implement this government policy is by changing from fuel to batteries on fishing boats, as well as building energy stations throughout the waters of the Madura Strait. Therefore, this research aims to design a floating energy station based on solar panels and wind turbines to cover the needs of four 10 GT fishing boats with a battery capacity of 90 kWh. Based on numerical methods and trial and error according to weather data, the floating energy station uses 135 solar panels of 550 Wp and 16 wind turbines of 2 kW used to charge 300 batteries of 24 Volts, 100Ah. All batteries can be recharged in 8.5 hours.

Published: December 2024

Abstract
Tree inventory is crucial in managing road trees in urban areas. In Indonesia, roadside trees in public areas are managed by local governments. However, local governments, including Denpasar, have limited tree management resources, such as a lack of budget, low resource capacity, limited numbers of field staff, and incomplete equipment. Under these conditions, local governments can only conduct tree inventories on a small percentage of roadside trees using traditional (paper-based) methods that are time-consuming and poor database management. As a result, the city government does not have complete data for managing roadside trees, including anticipating failure that threatens public safety and property. It is necessary to improve roadside tree inventory methods that can be self-carried out by local governments within the limitations they have. This study examines the time required to record several trees using a mobile application-based field survey method and a mobile mapping system. This study used 1386 roadside trees to be recorded using the mobile application-based field survey method and 12,846 trees to be recorded using the mobile mapping system. The study results show that the mobile application-based field measurement method takes about 11.5 minutes to collect tree data consisting of the local name, diameter, height, tree damage, trunk slope, and tree coordinates. As for the mobile mapping system method, the time needed to collect data for 12,846 trees is 5 days (7 working hours) to record pictures (acquisition) and 15 days to process the recorded images to produce tree data.

Abstract
Banten Forest Management Unit (FMU) is undertaking an effort to develop sengon (Falcataria falcata) as a wood-producing commodity alongside teak, acacia, and mahagony. Local farmers carrying out sengon propagation assist in this development effort. Improper practices of propagating and cultivating sengon and the need for more public knowledge regarding pests and diseases that attack sengon raise questions regarding the public’s perception of cultivation techniques and control of plant pests and diseases. Training on sengon cultivation and introducing pests and diseases on sengon plants was held on 25 November 2023 at the Cigembor Wood Collecion Place (WCP), inten Jaya Village, Lebak, Banten. In total, 30 participants who were members of a forest local community (LMDH) at Perum Perhutani FMU Banten attended this activity. The training method involves presentations and direct practice in the field. The results of the pre- and post-test evaluation showed an increase of 25% in knowledge of pests and diseases in sengon plants and 10% in knowledge of sengon cultivation. The test results also showed that 8 out of 10 participants could differentiate between forest pests and diseases. Furthermore, 10 out of 10 participants knew the harvest age for sengon. In general, this training increased the participants’ knowledge and experience in cultivating sengon and identifying pests and diseases in sengon plants.

Published: December 2024

Abstract
Enhanced Recovery After Surgery (ERAS) protocols are evidence-based care improvement pathways which are perceived to expedite patient recovery following surgery. Their utility in the setting of oesophagectomy remains unclear. The aim of this study was to perform a systematic review and meta-analysis of randomised clinical trials (RCTs) to evaluate the impact of ERAS protocols on recovery following oesophagectomy compared to standard care. A systematic review was performed in accordance with preferred reporting items for systematic reviews and meta-analyses guidelines. Meta-analysis was performed using Review Manager (Version 5.4). Six RCTs including 850 patients were included in this meta-analysis. Overall complication rate (Odds Ratio (OR): 0.35, Confidence Interval (CI): 0.21, 0.59, P &lt; 0.0001), pulmonary complications (OR: 0.40, CI: 0.24, 0.67, P = 0.0005), post-operative length of stay (LOS) (OR -1.88, CI -2.05, −1.70, P &lt; 0.00001) and time to post-operative flatus (OR: -5.20, CI: −9.46, −0.95, P = 0.02) favoured the ERAS group. There was no difference noted for anastomotic leak (OR: 0.55, CI: 0.24, 1.28, P = 0.17), cardiac complications (OR: 0.86, CI: 0.30, 2.46, P = 0.78), gastrointestinal complications (OR: 0.51, CI: 0.23, 1.17, P = 0.11), wound complications (OR: 0.85, CI: 0.28, 2.58, P = 0.78), mortality (OR: 1.37, CI: 0.26, 7.4, P = 0.71), and 30-day re-admission rate (OR: 1.29, CI: 0.30, 5.47, P = 0.73) between ERAS and standard care groups. ERAS implementation improved post-operative complications, LOS, and time to flatus following oesphagectomy. These results support the robust adoption of ERAS in patients indicated to undergo oesphagectomy.
Hydrocarbon metabolism and petroleum seepage as ecological and evolutionary drivers for Cycloclasticus

Published: December 2024

Abstract
Aqueous-soluble hydrocarbons dissolve into the ocean’s interior and structure deep-sea microbial populations influenced by natural oil seeps and spills. n-Pentane is a seawater-soluble, volatile compound abundant in petroleum products and reservoirs and will partially partition to the deep-water column following release from the seafloor. In this study, we explore the ecology and niche partitioning of two free-living Cycloclasticus strains recovered from seawater incubations with n-pentane and distinguish them as an open ocean variant and a seep-proximal variant, each with distinct capabilities for hydrocarbon catabolism. Comparative metagenomic analysis indicates the variant more frequently observed further from natural seeps encodes more general pathways for hydrocarbon consumption, including short-chain alkanes, aromatics, and long-chain alkanes, and also possesses redox versatility in the form of respiratory nitrate reduction and thiosulfate oxidation; in contrast, the seep variant specializes in short-chain alkanes and relies strictly on oxygen as the terminal electron acceptor. Both variants observed in our work were dominant ecotypes of Cycloclasticus observed during the Deepwater Horizon disaster, a conclusion supported by 16S rRNA gene analysis and read-recruitment of sequences collected from the submerged oil plume during active flow. A comparative genomic analysis of Cycloclasticus across various ecosystems suggests distinct strategies for hydrocarbon transformations among each clade. Our findings suggest Cycloclasticus is a versatile and opportunistic consumer of hydrocarbons and may have a greater role in the cycling of sulfur and nitrogen, thus contributing broad ecological impact to various ecosystems globally.
The Dynamics of Banking and Insurance

Published: December 2024

Abstract
Banking and insurance share an origin but have distinct evolutionary paths. First, this chapter traces the history of both sectors from their shared origins to the transformations brought by industrialization, crises, and state regulation. Then the chapter compares the dynamics in both industries focusing on risk, regulation, and societal and technological changes. Managing risk is the main dynamic that shaped both banking and insurance from the very start. Regulation introduced external risk management and turned out to be the single most influential dynamic. Shifts in social strata significantly shaped product offerings and uptake from the 18th century on, as lower-income households became able to save up. Recently, digital access further ‘democratized’ financial services. In the final part, the chapter assesses the future of the insurance and banking industry in light of the dramatic changes of the early 21st century, suggesting that the traditional distinction between the two is becoming less useful. This is not so much due to their convergence but to the addition of alternative providers both from within and from outside the financial sector.

Published: December 2024

Abstract
Dynamic change has characterized the history of the modern chemical industry from its inception in the early 19th century to the present. This article departs from previous studies of the industry’s evolution by dividing the history of the industry into five distinct periods. Each has entailed fundamental changes in the industry’s products, processes, main actors, and other aspects, and therefore alterations to its fundamental character. The main drivers and impacts of change over time have included technology, in particular application of theoretical science for product and process innovation; feedstocks; the companies populating the industry; government policy, especially with regard to intellectual property; and globalization.
Age Groups and Civic Subdivisions
Authors: Kennell Nigel 
Published: December 2024

Abstract
This chapter surveys the major civic divisions in the Greek cities of the Roman Empire. It traces the Hellenistic origins and Imperial-period developments of the constituent grades of the citizen training systems (paides, ephēboi, neoi), as well the corporate groupings of older citizens (presbuteroi, gerousiai) that appeared shortly before the Imperial period and became predominant in later centuries. The roles of the officials and staff involved in citizen training are examined, together with elements of the curriculum. The relationship between the presbuteroi and gerousiai is likewise discussed, along with their powers and functions. The overview concludes with an account of the oldest and most enduring civic divisions, the originally fictive kinship groups known as phylai and their subdivisions in various cities.
