This study aims to evaluate the level of heavy metal pollution and the potential ecological and human health risks in the waters of Selangan, Bontang City. The research focuses on analyzing the concentrations of iron (Fe) and mercury (Hg) in sediment, considering that both elements are toxic, persistent, and capable of bioaccumulating within the food chain. The study was conducted over six months, from January to June 2023, at four sampling stations representing the environmental conditions of Selangan waters. The methodology included sediment sampling, sample preparation through drying and grinding, and laboratory analysis using Inductively Coupled Plasma–Optical Emission Spectrometry (ICP-OES) to determine Fe concentrations. The results were then compared with quality standards established by the Washington Annotated Code 173-204-320 and Indonesia’s National Agency of Drug and Food Control (BPOM) Regulation No. 5 of 2018. The findings indicate the presence of heavy metal contamination across all sampling stations. Fe concentrations ranged from 2.35 mg to 6.308 mg, significantly exceeding the permissible limit of 0.3 mg/L. Meanwhile, Hg concentrations ranged from 0.015 mg to 0.028 mg, also surpassing the standard threshold of 0.001 mg/L. These results clearly demonstrate heavy metal pollution in the Selangan waters, posing potential threats to marine ecosystem health and coastal communities. Regular monitoring and mitigation measures are urgently recommended to prevent further environmental degradation.

The growth of the digital economy has accelerated the development of online shops as part of digital MSMEs; however, this growth has not been fully supported by systematic financial management practices. This study aims to analyze financial management strategies applied by online shops in Parepare City based on four main indicators: financial planning, recording, reporting, and control. This research employed a qualitative approach within a postpositivist paradigm. Data were collected through participatory observation, semi-structured interviews, and documentation from five online shops selected using purposive sampling. Data analysis followed an interactive model consisting of data reduction, data display, and conclusion drawing, while data credibility was ensured through source and method triangulation. The findings reveal that financial management practices have been implemented by all research objects but remain at a basic level. Financial planning is primarily short-term and experience-based, financial recording is predominantly manual, financial reporting does not yet include formal profit and loss analysis, and financial control lacks measurable quantitative indicators. These results indicate that the main challenge in online shop financial management lies not in the absence of financial practices, but in the quality of implementation and the use of financial data for strategic decision-making. This study is expected to contribute empirically to the literature on digital MSME financial management and provide practical guidance for online shop owners to improve sustainable financial management practices.

Prompt injection has emerged as a critical security threat for Large Language Models (LLMs), exploiting their inability to separate instructions from data within application contexts reliably. This paper provides a structured review of current attack vectors, including direct and indirect prompt injection, and highlights the limitations of existing defenses, with particular attention to the fragility of Known-Answer Detection (KAD) against adaptive attacks such as DataFlip. To address these gaps, we propose a novel, hybrid, multi-layered detection framework that operates in real-time. The architecture integrates heuristic pre-filtering for rapid elimination of obvious threats, semantic analysis using fine-tuned transformer embeddings for detecting obfuscated prompts, and behavioral pattern recognition to capture subtle manipulations that evade earlier layers. Our hybrid model achieved an accuracy of 0.974, precision of 1.000, recall of 0.950, and an F1 score of 0.974, indicating strong and balanced detection performance. Unlike prior siloed defenses, the framework proposes coverage across input, semantic, and behavioral dimensions. This layered approach offers a resilient and practical defense, advancing the state of security for LLM-integrated applications.

This study aims to analyze the opportunities, threats, strengths, and weaknesses of Arch Barbershop, a modern barbershop in Maumere City. The study was conducted using a descriptive approach through observation of the business environment, competitor analysis, and identification of local consumer preferences. The analysis shows that Arch Barbershop has promising opportunities due to the increasing trend of grooming among teenagers and young adults, and the lack of barbershops offering modern and consistent service concepts in the area. However, this business also faces threats in the form of competition from new barbershops, rapidly changing consumer preferences, and dependence on barber skills as the spearhead of service quality. Furthermore, internal weaknesses such as limited space, inflexible operating hours, and a less than optimal variety of services pose challenges to business development. By understanding these opportunities, threats, strengths, and weaknesses, Arch Barbershop can formulate a more effective development strategy to increase its competitiveness and business sustainability in Maumere City.

This journal analyzes sexual violence by educators against students by analyzing Supreme Court Decision No. 5642 K/Pid.Sus/2022 using normative legal research methods. The primary focus of this research is the abuse of power relations by perpetrators holding positions of authority, as well as the legal protections afforded to child victims. Furthermore, this paper compares the provisions on sexual violence in the Child Protection Law and the Sexual Violence Criminal Law (UU TPKS). The findings indicate that courts impose harsher sentences on perpetrators who abuse their trust as educators and place victims at the center of the legal process, ensuring guarantees of recovery, psychological rehabilitation, restitution, and the right to education. The judges' approach in the ruling also reflects the spirit and principles of victim protection as outlined in the TPKS Law, including recognition of power dynamics, psychological pressure, and the importance of a victim-centered perspective. The TPKS Law expands the scope of sexual violence beyond physical aspects to include psychological and structural dimensions, which were previously not clearly regulated in other laws.  Therefore, this paper emphasizes the importance of harmonizing the two laws to create a more just, progressive, and victim-centered legal system, especially for children in educational settings. This research is expected to contribute to strengthening a more comprehensive and child-oriented legal approach.

Currently, the skills needed to advance a tourist area are influenced by the availability of human resources who can speak English and understand local culture well. Unfortunately, improving English proficiency remains a challenge. Additionally, another issue appears as the Alpha generation is exposed to a great deal of English-language social media content; however, this does not appear to be directly correlated with an improvement in their English proficiency. It appears that the English Club instructors at SMA Fons Vitae 1 Jakarta were also aware of these two problems. Therefore, on September 11, 2025, an ABDIMAS activity entitled "Giving and Asking for Direction" training was held with the production of a short film. This activity was attended by 15 participants, 10 boys and 5 girls, a combination of students from grades 10 and 11. The results of the training showed that the pre-production process of making a short film provided a space for participants to recognize and explore Indonesian cultural heritage. Furthermore, the production process of making a short film made participants not afraid of speaking English. In the post-production process, participants can also edit parts of the video that are less than satisfactory because they can re-record if there are errors in pronunciation and grammar.

This study aims to examine pragmatic aspects, particularly speech acts and implicatures, in the lyrics of the song “Sedia Aku Sebelum Hujan” by Idgitaf. By applying a qualitative descriptive method through pragmatic content analysis techniques, this study examines locutionary, illocutionary, and perlocutionary speech acts based on Austin's theory, as well as conversational implicatures based on Grice's framework. The results show that the song lyrics are dominated by expressive and commissive illocutionary acts that serve to express sacrifice, vulnerability, and unconditional commitment. Locutionary acts play a role in constructing a literal narrative about protection and relationship inequality, while perlocutionary acts are aimed at evoking feelings of security and gratitude in the listener. Furthermore, the study of implicature reveals deeper implied meanings related to self-sacrifice, acceptance of inequality in relationships, and anticipatory commitment, which are often conveyed through the metaphors of “rain” and “war”. This study concludes that the power of lyrics lies not only in explicit romantic expressions, but also in the strategic use of language to perform actions and convey implicit values of devotion, reflecting the complex dynamics of human relationships, even when they are unbalanced. These findings emphasize the importance of pragmatic analysis in fully understanding the communicative and artistic impact of song lyrics.

This research focuses on optimizing the control system to improve voltage stability in a 10 kW Solar Power Plant (PLTS) located in a tropical region. The main issue addressed is voltage fluctuation caused by the intermittent nature of solar radiation (200–1200 W/m²) and temperature variations (20–50°C), which result in up to 12% overshoot in the inverter. The proposed method implements a Proportional-Integral-Derivative (PID) controller optimized using the Particle Swarm Optimization (PSO) algorithm with real-time irradiation input data. The research integrates a 100 Hz digital low-pass filter to mitigate sensor noise under low irradiation conditions. Simulation results show that the PID-PSO system successfully reduces overshoot from 12.1% to 4.2% under high irradiation, and decreases settling time from 0.62 seconds to 0.31 seconds. The digital filter effectively reduces measurement deviation from 7.2% to 2.8% at 200 W/m² irradiation. The PSO optimization achieved optimal convergence within 37 iterations with an Integral of Time-weighted Absolute Error (ITAE) value of 0.18. This study concludes that the implementation of PID-PSO with a digital filter significantly enhances the voltage stability of the PLTS by 20.3% compared to conventional PID control and is ready to be applied in tropical-region smart grid systems.

Self-harm among adolescents is a mental health problem influenced by various psychosocial factors, including family support. The family serves as the primary support system that can protect adolescents from the effects of stress and maladaptive coping behaviors. This study aimed to analyze the relationship between family support and the incidence of self-harm among adolescents. The study employed an analytic quantitative design with a cross-sectional approach. The research sample consisted of 476 adolescents selected using a cluster random sampling technique. Family support was measured using the Perceived Social Support–Family (PSS-Fa) questionnaire, while the incidence of self-harm was assessed using the Self-harm Inventory (SHI). Data were analyzed using the Spearman Rank test. The results showed that the majority of respondents had high levels of family support (65.8%) and did not engage in self-harm (78.2%). Bivariate analysis indicated a significant relationship between family support and the incidence of self-harm among adolescents (p < 0.001), where adolescents with high family support were more likely to be in the non–self-harm category, while mild and severe self-harm were more commonly found among adolescents with low family support. This study concludes that family support plays an important role as a protective factor against self-harm among adolescents. Strengthening the role of the family should be a key focus in family-based nursing interventions for the prevention of mental health problems in adolescents.

This study aims to analyze the supervisory strategy of the Panwascam (Central Election Supervisory Agency) of Sinjai Borong District in handling election violations in the 2024 Simultaneous Regional Elections in Sinjai Regency. The study focuses on two main aspects, namely preventive strategies and repressive strategies. The research method uses a qualitative approach with case studies, through in-depth interviews, observation, documentation, and interactive data analysis. The results show that the Panwascam's preventive strategies include socialization of election regulations, political education, and strengthening coordination with village officials and community leaders. This strategy has been proven to increase regulatory understanding among lower-level election organizers and public political awareness, especially first-time voters. Meanwhile, the repressive strategy is implemented through violation handling mechanisms, preparing legal recommendations, and summoning perpetrators and witnesses. Based on field findings, the Panwascam successfully handled one case of violation of ASN neutrality that was recommended to the Regency Bawaslu. This study concludes that the supervision of the Sinjai Borong Panwascam is relatively effective, although it still faces limited resources, low public legal literacy, and strong local political patronage. The results of this study provide a conceptual contribution to strengthening the community-based electoral supervision model, which integrates regulatory, educational, and collaborative aspects. They also serve as practical recommendations for improving the quality of electoral democracy at the local level.
