The Pesanggrahan Dalem Paku Buwono IX (PB IX) is situated in Langenharjo Village, Sukoharjo Regency, Indonesia. The site was founded in 1870 by PB IX (1830-1893), but it is currently facing environmental degradation, despite its past pristine water and natural hot springs. However, with the new management takeover by GPH Wicaksono, a descendant of the Surakarta Royal Family, there is hope for the conservation of this heritage site. This research explores servant leadership practices within the cultural context of GPH Wicaksono as the manager of heritage site in Langenharjo village. Drawing on Greenleaf's servant leadership principles, it examines how Javanese culture, and the wisdom of the manager can foster collective engagement in environmental preservation. The study aimed to provide valuable insights into leadership's role in promoting sustainability for the heritage site and the local community. The identification of servant leadership implementation in the heritage site was using a qualitative approach. Data collection involves on-site observations and in-depth interviews with relevant stakeholders, including community leaders, members of the community, and cultural enthusiasts. The data is analyzed using phenomenology analysis to identify specific servant leadership behaviors of site manager and their role in fostering environmental preservation and sustainability within the community. The study's findings showed that the manager is dedicated to preserving the heritage site by promoting strong ties with Javanese culture and tradition. He encourages an eco-friendly mindset and collective participation to sustainably protect the environment. He also values effective communication and respects his colleagues, which in turn fosters trust and empowerment among the team. By following principles of Javanese culture, he leads and empowers communities toward environmental sustainability. This study contributes to the importance of incorporating cultural values in leadership practices to foster collective engagement and green awareness for long-term environmental preservation. It serves as an initial study for further research using quantitative analysis to deepen our understanding of servant leadership’s effectiveness in diverse cultural contexts.

The Dhaka Metro Rail Line 1, also known as DMRT Line 1, is the first subterranean metro rail project in Bangladesh, and is currently undergoing depot construction work under contract package-1 (CP 01). The construction of depot work is mainly susceptible to ambient air quality due to the land development and soil improvement activities. The long-term construction period can significantly impact the surrounding air quality of the project area and so it is crucial to identify air pollution concerns and analyze the impact of air quality on the environment. This study evaluated ambient air quality in four distinct zones of the depot area from June 2023 to September 2024. There were several pollutants measured in the ambient air including Particulate Matters (PM10 and PM2.5), Ozone (O3), Lead (Pb), Sulfur Dioxide (SO2), Nitrogen Dioxide (NO2), Carbon Monoxide (CO). The air quality monitoring machine Oceanus AQM-09 and Haz-Scanner (HIM, 6000) were used for 8 hours on the site. The power-law equation of Schroeder and Jugloff, 2012 was applied to provide 24-hour and 8-hour averages for the air quality parameters. It is observed that in pre-monsoon period of 2024, there is quite high intensity of particulate matter (PM2.5) present in the air, whereas other air pollutants values were found in all four zones are moderate in the air samples as prescribed by Air Pollution Control Rules, 2022.

The mangrove area in Tritih Cilacap, Central Java is decreasing due to illegal logging. This affects the distribution pattern of gastropods. This study aims to determine the distribution pattern of gastropods and provide information related to physical chemical factors that play a role in gastropod distribution patterns. This study was conducted at five sampling points. Five sampling points from the sea to the land. The sampling method used for gastropods was collection from 1x1 m plots. Gastropods in the plot were collected by hand on the top of the sediment and in the sediment were taken 10 cm deep using a corer with 3 repetitions for each station. Environmental parameters measured were: temperature, salinity, organic matter content, pH, and substrate type. The distribution of gastropods in Tritih Cilacap mangrove forest has a clustering and random pattern. There were 11 species of gastropods found from 7 families. Gastropod species that have clustered distribution patterns are: Ceritidhea alata, Telescopium telescopium, Neritina violacea, Neritina zigzag, Chicoreus capucinus, and Assimenia brevicula. Gastropod species that have random distribution patterns are: Ceritidhea quadrata, Neritina lineata, Cassidulla aurisfelis, Cassidulla nucleus, and Littoraria carinifera. The results of BIOENV analysis showed that the most influential environmental factors on gastropod density were water temperature, salinity, organic matter content and sand substrate.

The extractive political economy chosen by the New Oder since the beginning of its rule has transformed natural resource-rich areas in Indonesia into areas at the heart of global capitalism. In the past, extractive politics began by opening the tap for foreign capital to exploit forests, converting scrubland into monoculture plantations and exploiting coal deposits. At the same time, colonial demographic politics were revived to open up major extractive areas, transforming scrubland from former HPH concessions into agricultural areas, alongside coal mining exploration. Tenggarong Seberang District, East Kalimantan has experienced social reconfiguration many times, from an area with a subsistence production model to a major coal extractive area in Kutai Kartanegara Regency. This article describes how Manunggal Jaya Village, which was previously managed by the local farming community, became a center for transmigrant settlements that successfully transformed the village into a center for Kutai rice farming during the New Order era; and drastically changed into a center for supporting services for the multinational mining industry after regional autonomy. The research was conducted for 2 months involving 3 researchers, 2 research assistants throughout August-October 2024. Primary data was collected through observation and in-depth interviews with 10 key informants. The results of the study found a social reconfiguration of the position and role of transmigrant farmers in Tenggarong Seberang. Transmigrants came from poor areas in East Java, became the dominant social class throughout the 1980s-90s, changed drastically into the most vulnerable marginal class entering the mid-2000s. Agricultural land conversion to mining sites, reduced government support; pressures from companies, village bureaucrats, and land brokers have placed significant burdens on farmers. They face water scarcity, land degradation, pollution, new pests, and psychological stress; discouraging younger generations from farming and leaving remaining farmers to struggle under these challenges.

This is one of the greatest challenges in computer network security and cannot be dealt with without a set of most recent detection techniques. This paper lays down a new hybrid technique that combines Clustering-Based Local Outlier Factor (CBLOF) and Extreme Gradient Boosting (XGBoost) to enhance accuracy while detecting Distributed Denial of Service (DDoS) from network traffic. The proposed hybrid model utilizes a CBLOF for outlier detection as feature engineering. Over the detected anomalies, classification is to be done using XGBoost classification to attain the objective. The proposed hybrid model was tested extensively on CICIDS 2017 and CICIDS 2018 datasets Compared with traditional ones, the proposed model outperformed the traditional ones with an accuracy rate of 99.99%, precision of 100%, and F1 score reflecting perfection. These results confirm this model's efficiency in terms of known and novel attack patterns and introduce a further reliable framework for the timely detection of DDoS attacks. Even if it is computation-heavy, optimization could be made towards real-time large-scale data.
