ASSESSMENT OF WATER QUALITY IN SITU TLAJUNG HILIR USING POLLUTION INDEX AND SAPROBIC QUOTIENT APPROACHES
Get PDFSitu Tlajung Hilir is a natural lake in West Java, utilized by the local community to support livelihoods and contributing to the balance of the surrounding ecosystem. However, pollution from industrial and residential activities has raised concerns over its declining water quality. This study aims to assess the water quality of Situ Tlajung Hilir using the Pollution Index (PI) and Saprobic Quotient (SQ) methods. A descriptive quantitative approach with purposive sampling was conducted at four observation stations. Research activities included field observation, sample collection, measurement of physical, chemical, and biological parameters, and laboratory analysis. Instruments were calibrated prior to use. PI values ranged from 1.02 to 1.04, indicating a slightly polluted status based on the Decree of the Minister of Environment No. 115 of 2003. SQ values ranged from -0.10 to -0.79, reflecting moderate to fairly heavy pollution. The PI analysis showed that dissolved oxygen (DO) and temperature did not meet Class III water quality standards. SQ analysis revealed a dominance of Euglenophyceae and Paramecium (Ciliates), both indicators of organic pollution. In conclusion, the water quality of Situ Tlajung Hilir is categorized as slightly to fairly heavily polluted. Emphasizing the need for ongoing monitoring and improved waste management to protect the aquatic ecosystem
Legal Analysis of Punishment for Perpetrators of Violence Against Children in the Perspective of Substantive Justice (Study of Decision Number 103/Pid.Sus/2017/PN Psb)
Get PDFThis study aims to analyze the application of the law to perpetrators of child abuse in Decision Number 103/Pid.Sus/2017/PN Psb and to assess the extent to which the decision reflects the principles of justice and legal protection for child victims. The phenomenon of violence against children in Indonesia continues to increase, but the response of criminal justice often does not fully support the best interests of children. A qualitative approach with a case study design was used in this study, focusing on one court decision as the unit of analysis. Data were collected through court decision documentation, literature studies, and reviews of laws and regulations, which were analyzed descriptively-qualitatively to reveal the suitability of the application of the law to the principles of child protection. The results of the study indicate that normatively, the judge has applied the provisions in Article 80 paragraph (1) in conjunction with Article 76C of Law No. 35 of 2014 by imposing a sentence on the defendant. However, the decision does not fully reflect substantive justice because it does not contain an order for psychological recovery for child victims. This finding indicates that the legal approach still tends to be repressive and has not touched on holistic aspects of recovery. This study contributes to the understanding of the weaknesses of the juvenile criminal justice system in ensuring comprehensive justice. Further research is recommended to examine the implementation of the decision and its impact on the psychosocial conditions of child victims of violence
Analyzing the Effectiveness of Network-Centric Warfare-Based Defence Strategies In Responding to Asymmetric Threats: A Quantitative Approach
Get PDFThis study examines the impact of Network-Centric Warfare (NCW)-based defence strategies on military effectiveness in countering asymmetric threats. Focusing on three critical dimensions—Information and Communication Integration, Command-and-Control (C2) Interoperability, and Adaptive & AI-Capable NCW Systems—the research adopts a quantitative methodology using Structural Equation Modeling (SEM) to assess their influence. Asymmetric threats, characterized by unpredictable, unconventional tactics, require military forces to adapt rapidly and operate with high coordination. The findings indicate that NCW-based strategies significantly enhance military capabilities in terms of responsiveness, adaptability, and operational coordination. The integration of real-time information and communication technologies enables better situational awareness and informed decision-making. C2 interoperability ensures seamless collaboration among units and branches, while adaptive systems enhanced with artificial intelligence provide strategic advantages in dynamic conflict environments. This study highlights the importance of transitioning from traditional, platform-centric models to network-enabled operations, thereby enabling effective responses to contemporary security challenges. The empirical evidence supports the strategic value of NCW in enhancing combat readiness and operational performance. By validating these relationships, the study contributes to the body of knowledge on defence innovation. It offers practical insights for military planners and policymakers in strengthening national security through technology-driven strategies

Comparison of K-Means and K-Medoids Methods in Clustering High Population Density Areas in Bireuen Regency
Get PDFThis study examines the population density distribution in Bireuen Regency by applying two clustering algorithms, namely K-Means and K-Medoids, to demographic data from 2019 to 2023. Three main variables were used: total population, number of ID card holders (KTP), and number of households (KK). The clustering results identified three primary groups: very dense, dense, and not dense. Districts such as Kota Juang, Jeumpa, and Peusangan consistently fell into the very dense category, while districts like Pandrah, Gandapura, and Makmur tended to be classified as not dense. Cluster quality was evaluated using the Davies-Bouldin Index (DBI). The evaluation results showed that the K-Means algorithm performed better in most years analyzed, particularly in 2020 with the lowest DBI value of 0.3906. Meanwhile, in 2023, K-Medoids outperformed K-Means, with a DBI value of 0.7724. These findings indicate that K-Means is more effective in handling homogeneous data, whereas K-Medoids is more adaptive to data containing outliers or irregular patterns. Overall, the choice of clustering method depends on the characteristics of the data used. The results provide a spatial overview of population distribution that can support regional planning and data-driven public policy. These findings are expected to serve as a basis for more targeted and equitable regional development planning. For future research, it is recommended to expand the analysis by including additional variables such as area size and socioeconomic indicators, as well as optimizing the number of clusters using methods like the Elbow method or Silhouette Score

No full textThis study investigates the influence of social media on political involvement and public involvement activities throughout Delta State alongside its capacity to expedite immediate information distribution public discussions and community organization. According to the Uses and Gratifications Theory, individuals select their social media engagement through personal objectives and political beliefs. Ethiope East and Ethiope West are the main focus while Isiokolo and Oghara town were specifically selected as the population for the study. A sample size of 400 participants revealed that participants follow political news on social media platforms. A structured questionnaire was distributed electronically and in hardcopies to collect data on social media usage patterns, political participation, and civic engagement levels. The data analysis was done using descriptive and inferential statistics as Spearman Rank was used to test the hypothesis. The analysis showed that political accessibility depends on cultural collectives together with political capacity, social constraints, education, and economic background. It is recommended therefore that governments, academic institutions, and civil society organisations should create programs to teach citizens how to differentiate between reliable political information and false information, guaranteeing responsible and informed civic engagement by improving their critical thinking and digital.Penelitian ini menyelidiki pengaruh media sosial terhadap keterlibatan politik dan aktivitas keterlibatan publik di seluruh Delta State, serta kemampuannya untuk mempercepat distribusi informasi secara langsung, diskusi publik, dan organisasi komunitas.
