This study discusses the design and testing of a growing media moisture and water level monitoring system based on ESP32-MQTT. The system was developed to support real-time monitoring of growing media conditions and water availability through a monitoring dashboard. This research used an experimental method with a design and implementation approach by developing an ESP32 circuit connected to a capacitive soil moisture sensor and a water level sensor, then sending sensor data to the dashboard through the MQTT protocol and Node-RED. Testing was carried out using a plant pot as the moisture testing medium and a water container as the water level testing medium. The results showed that the growing media moisture sensor displayed 0% in dry and very dry soil conditions, 61% in moist soil, and 89% in very moist soil. The water level sensor displayed 0 cm, 2.4 cm, and 4 cm according to the testing conditions. These results indicate that ESP32-MQTT can be used as an initial prototype for monitoring growing media moisture and water level before being applied to a complete hydroponic or aquaponic system.

This research critically investigates the circulation of disinformation concerning the instability of fuel prices on the digital platform X and its subsequent implications for the polarization of modern society. In an era where unverified economic news frequently dictates public reaction, fake news often acts as a potent catalyst for mass anxiety. By implementing a quantitative framework driven by lexicon-based computational sentiment analysis, this study effectively processed a dataset of 500 public opinion samples extracted via Google Colab spanning from April 2024 to April 2026. To ensure computational accuracy and eliminate textual noise, the data underwent a rigorous preprocessing phase encompassing case folding, alongside the systematic removal of URLs, account mentions, numbers, hashtags, and punctuation marks. The statistical outcomes revealed a highly disproportionate emotional landscape, overwhelmingly dominated by 451 negative reviews. In stark contrast, neutral observations and positive affirmations were nearly absent, recording only 40 and 9 instances, respectively. The data compellingly illustrates that the relentless influx of pessimistic narratives regarding economic instability directly induces financial panic, undermines rational discourse, and severely fragments cyberspace into deeply polarized factions.

He rapid advancement of digital technology has significantly transformed human life, particularly in the way information is accessed, processed, and distributed. While this development brings numerous benefits, it also generates serious challenges such as information overload, misinformation, and the decline of critical thinking skills among digital users. This study aims to examine the relevance of the philosophical thought of Al-Kindi on intellect (aql) and knowledge in addressing these contemporary issues within the digital era. The research employs a qualitative approach through library research, analyzing classical philosophical texts and contemporary scholarly works related to epistemology and digital literacy. The findings show that Al-Kindi positions intellect as the primary faculty of human beings in understanding truth and organizing knowledge systematically and rationally. According to Al-Kindi, knowledge must be grounded in logical reasoning to achieve certainty and clarity. In the context of the digital era, this perspective is highly relevant as individuals are required to critically evaluate vast and unfiltered information circulating in digital spaces. This study concludes that Al-Kindi’s rational philosophy provides a strong intellectual foundation for developing digital literacy, strengthening critical thinking skills, and promoting responsible engagement with technology in modern society.

This study aims to explore the implementation of communication within routine counselling programmes as an intervention strategy to address student mental health issues at SMP Tri Guna Bhakti Surabaya. The investigation focuses on three primary problems: broken home backgrounds, lack of parental attention, and economic limitations. This research employed a qualitative descriptive approach, collecting data through in-depth interviews, participatory observation, and documentary studies involving school counsellors, teachers, students, and parents. Grounded in Interpersonal Communication Theory and Therapeutic Communication Theory, the analysis reveals that routine counselling programmes serve as a vital communication platform enabling empathetic, open dialogue between counsellors and students experiencing psychological distress. Key findings indicate that effective counselling communication requires consistent trust-building, active listening, and culturally sensitive message delivery tailored to each student’s unique circumstances. However, the study identifies significant systemic barriers, including student reluctance to disclose personal problems due to social stigma, limited counsellor availability, and insufficient parental engagement in follow-up communication. Despite these critical challenges, the implementation of the programme demonstrates substantial positive outcomes, including reduced student anxiety, improved academic motivation, and fostered psychological resilience. The study concludes that integrating structured interpersonal and therapeutic communication strategies within school counselling frameworks is essential for creating supportive, inclusive educational environments. These strategies are crucial to effectively address the multifaceted, urgent mental health needs of adolescents from vulnerable socioeconomic backgrounds, providing a scalable model for similar urban educational institutions.

This study aims to identify and analyze Ramadan-specific lexicons used by Indonesian Muslim communities on social media, as well as to describe the cultural meanings embedded within them. The study employs an anthropolinguistic approach with a descriptive qualitative method. Data were collected through observation and note-taking techniques from three social media platforms X (Twitter), TikTok, and Instagram during the Ramadan 1446 H/2025 period. A total of 32 Ramadan-specific lexicons were identified and classified into three categories: greetings and expressions (12 items), worship-related lexicons (10 items), and culinary lexicons (10 items). The findings reveal that Ramadan lexicons circulating on social media reflect a blend of Islamic religious values, local Indonesian cultural traditions, and the influence of digital globalization. The hybrid nature of the language used — including code-mixing between Indonesian, Arabic, and English — illustrates the dynamic cultural identity of contemporary Indonesian Muslims. Ultimately, this study affirms that language is a living mirror of culture, one that continues to evolve alongside social and technological change.

The implementation of smoking prohibition policies in Islamic boarding schools continues to depend largely on manual monitoring methods, which often face challenges related to consistency and supervision range. This study aims to design an Internet of Things (IoT)-based cigarette smoke detection system as an alternative monitoring approach that is more effective, measurable, and sustainable. The system design combines an MQ-2 gas sensor with a NodeMCU ESP8266 microcontroller programmed through the Arduino IDE platform. When smoke levels detected by the sensor exceed the predetermined limit, the system automatically triggers a buzzer and LED as warning indicators while simultaneously sending monitoring data to cloud-based platforms such as Firebase or ThingSpeak for real-time observation through web interfaces. The research outputs include a comprehensive system design consisting of system architecture, electronic circuit schematics, flowcharts, and pseudocode that are systematically arranged to support future prototype development and implementation. Through this design, the proposed system is expected to provide an initial technological solution that can enhance the effectiveness of monitoring and enforcing smoke-free regulations within Islamic boarding school environments.

This study aims to analyze the impact of bullying on adolescents’ mental health through a literature review. The method used is a literature review, which involves the collection and analysis of various relevant scientific articles published in the last five years.  Data were obtained from journals and related scientific works, then systematically analyzed to identify patterns of association between bullying and adolescents’ mental health. The results of the review indicate that the majority of studies reveal a negative impact of bullying on mental health, such as the emergence of anxiety, depression, stress, low self-esteem, and difficulties in social interaction. However, some studies found that this relationship was not statistically significant, suggesting the role of other factors, such as social support, family circumstances, and an individual’s ability to cope with stress. In addition to affecting victims, bullying also impacts perpetrators and bystanders, making it a complex phenomenon. Therefore, comprehensive prevention and intervention efforts are needed through collaboration between schools, families, and the community.

Contract law recognizes the concept of force majeure as a mechanism to address extraordinary circumstances that hinder the performance of obligations, namely unforeseen events beyond the debtor’s control that may result in the release or suspension of obligations. However, this concept has limitations, as it does not encompass situations such as economic or monetary crises. In the development of international contract law, the UNIDROIT Principles of International Commercial Contracts 2016 (UPICC) introduce the concept of hardship as a response to fundamental changes in circumstances that affect the economic equilibrium of the parties. Although hardship has not been explicitly recognized in Indonesian law, it is considered more relevant for addressing such conditions.This study aims to examine the historical development of the concept of hardship and to analyze the implementation of its underlying values in Indonesian legal practice. The method employed is normative legal research, utilizing primary, secondary, and tertiary legal materials. The findings indicate that, despite the absence of explicit regulation within the national legal system, the values of hardship have been reflected in several court decisions through approaches grounded in fairness and contractual adjustment.The implication of this study is that the concept of hardship has the potential to be explicitly adopted into Indonesian contract law in order to fill existing legal gaps and provide a more adaptive solution to changing circumstances, particularly in addressing economic or monetary crises that fall outside the scope of the force majeure regime

Uterine myoma is a benign smooth muscle tumor of the uterus commonly found in women of reproductive age and may cause symptoms related to mass effect and hematologic disturbances. We report the case of a 41-year-old woman presenting with progressive vaginal pain for 3 months, accompanied by low back pain and impaired daily activities, without vaginal bleeding, vaginal discharge, fever, or urinary or defecatory symptoms. Laboratory examination revealed severe microcytic hypochromic anemia with a hemoglobin level of 4.7 g/dL, while ultrasonography demonstrated a 9.93 × 10.32 cm mass described as symmetric, well circumscribed, and hyperechoic, leading to a working diagnosis of uterine myoma with anemia. The patient was managed with general condition monitoring, intravenous fluids, analgesics, transfusion of four units of packed red cells, and laparotomy as definitive intervention. Following transfusion and surgery, the hemoglobin level increased to 9.4 g/dL and subsequently to 11.0 g/dL, accompanied by improvement in postoperative symptoms and clinical condition. This case demonstrates that a large uterine myoma may present predominantly with pelvic pain and functional impairment in the absence of vaginal bleeding. A comprehensive approach involving systematic evaluation, preoperative correction of anemia, appropriate surgical intervention, and postoperative monitoring is essential to improve safety and clinical outcomes in patients with symptomatic pelvic masses.

Gastritis is an inflammation of the gastric mucosa that often causes pain in the epigastric area, which can reduce patient comfort and quality of life. This condition requires treatment that is not only pharmacological, but can also be supported by non-pharmacological interventions such as warm compresses that function to provide a relaxing effect and improve blood circulation. This study aims to determine the effect of warm compresses on reducing pain intensity in gastritis patients. The research method used was descriptive with a case study approach on one patient treated in the inpatient ward. Data collection was carried out through interviews, observation, and documentation using the PQRST method to assess pain. The intervention in the form of warm compresses was given for three days with a frequency of once a day for ± 15–20 minutes in the epigastric area. The results showed a gradual decrease in pain intensity from a scale of 6 to a scale of 2 after the intervention, as well as an increase in patient comfort. The implications of this study indicate that warm compresses can be used as an effective, safe, and easy-to-implement independent nursing intervention to help reduce pain in gastritis patients and improve the quality of nursing care.

Type II Diabetes Mellitus is one of the chronic diseases whose prevalence continues to increase and has become a global health issue. A common complication in patients with Type II Diabetes Mellitus is peripheral circulatory disorders, which can be identified through the Ankle Brachial Index (ABI) examination—a non-invasive method used to detect peripheral artery disease. ABI testing is essential for early detection and prevention of serious complications such as diabetic ulcers.This study aims to describe the Ankle Brachial Index values in patients with Type II Diabetes Mellitus at Santa Elisabeth Hospital Medan in 2025. This research used a descriptive quantitative method with purposive sampling technique. The study sample consisted of 52 respondents from a total population of 109 patients diagnosed with Type II Diabetes Mellitus. Data collection was conducted through observation sheets and measurement of systolic blood pressure in the upper and lower extremities using a sphygmomanometer and stethoscope. The ABI value was calculated based on the ratio between the highest ankle systolic pressure and the highest brachial systolic pressure. Data were analyzed using tabulation techniques and presented in tables and diagrams. The results showed that the majority of respondents had normal ABI values (>0.90), totaling 33 individuals (63.5%), while 19 individuals (36.5%) experienced abnormal ABI values (≤0.90).Conclusion:The study concludes that most patients with Type II Diabetes Mellitus at Santa Elisabeth Hospital Medan had ABI values within the normal range. However, a considerable proportion with abnormal ABI indicates the necessity of routine ABI screening as a preventive measure against peripheral vascular complications in diabetic patients. This study is expected to serve as a reference in developing nursing interventions aimed at improving the quality of life for patients with Type II Diabetes Mellitus.

This research explores hedonistic lifestyle patterns as a social reality that grows within peer interactions, both in adolescence and adulthood. The investigation applies a qualitative descriptive literature review by examining national scholarly publications issued from 2016 to 2026. The findings indicate that hedonistic tendencies should not be interpreted merely as individual choices to seek enjoyment. Instead, they emerge from social processes shaped by interaction, peer influence, and shared norms that develop within a group. In this context, peer circles function as influential socialization agents, encouraging conformity so individuals can be accepted and avoid social exclusion. The study also identifies differences in underlying motivations across life stages. Among adolescents, hedonistic behavior is closely linked to identity exploration and self-definition. For adults, however, it is more associated with maintaining self-image, signaling social standing, and displaying markers of achievement. Overall, environmental dynamics, the expansion of consumer-oriented culture, and intensive exposure to social media play significant roles in strengthening this phenomenon in Indonesia.

Amid intense market competition, the profitability of manufacturing companies is not solely determined by sales volume but is highly dependent on the precision of financial management, particularly in managing the working capital cycle and operating cash flow circulation. This study aims to evaluate the relationship between Working Capital Turnover (X1) and Operating Cash Flow (X2) on Profitability (Y) in consumer goods industry companies listed on the Indonesia Stock Exchange during the 2022–2024 period. Using a quantitative approach and multiple linear regression analysis, this study processes 77 observations that have passed purposive sampling and outlier testing. The partial test results reveal contrasting findings: Working Capital Turnover (X1) does not have a significant effect on profitability, while Operating Cash Flow (X2) is proven to be a strong positive determinant. However, simultaneously, both variables have a significant influence on the financial performance of companies (Fhitung 24,008 > Ftabel 3,08), with operating cash flow acting as the dominant driving factor of profit. The implications of these findings emphasize that to maintain profit stability, management should prioritize the availability of cash generated from core operations, while investors should be more attentive to cash flow trends as an indicator of fundamental financial health before making investment decisions.

Discretion exercised by election management bodies constitutes an administrative instrument that is functionally necessary to prevent stagnation in electoral processes under conditions of legal vacuum, normative ambiguity, or extraordinary circumstances. However, in practice, discretionary decisions often generate public concern and expose election officials to the risk of criminalization, particularly when such discretion is assessed through a formalistic and result oriented criminal law paradigm. This study aims to analyze the construction of criminal liability of election administrators for the use of discretion in conditions of electoral stagnation, by examining the paradigm shift from the old Indonesian Criminal Code to the new Criminal Code and its implications for criminal law enforcement under the Criminal Procedure Code. This research employs a normative legal method using statutory, conceptual, and case approaches. The findings reveal that the old Criminal Code tended to facilitate policy criminalization by emphasizing formal violations and objective consequences, whereas the new Criminal Code introduces a substantive approach centered on subjective fault, official purpose, and rationality of action. Nevertheless, the lack of synchronization with the Criminal Procedure Code which remains focused on conventional evidentiary standards causes discretionary actions of election administrators to remain legally ambiguous. Therefore, harmonization between substantive criminal law and criminal procedure law, along with a transformation in law enforcement reasoning, is essential to ensure that discretion exercised by election officials is assessed proportionally, contextually, and in line with democratic principles.

Nahwu (Arabic grammar) is a fundamental discipline in learning the Arabic language, helping to prevent errors in speech and serving as a primary key to clearly understanding Islamic legal texts. However, in practice, the teaching of Nahwu often faces complex challenges, particularly the lack of active participation among female students and their uneven mastery of the subject. Therefore, this study aims to explore the problems in teaching Nahwu at Al-Madani Islamic Boarding School in Cikalong and to identify the factors causing these issues. This study aims to: (1) reveal the problems faced by second-grade female students of KMI in learning Nahwu at Al-Madani Islamic Boarding School in Cikalong, and (2) identify the contributing factors influencing the emergence of these problems. This research employs a descriptive qualitative approach. The researcher used three data collection techniques: classroom observation, in-depth interviews with the Nahwu teacher, and questionnaires distributed to the students. For data analysis, the researcher applied the Miles and Huberman model, which consists of data reduction, data display, and conclusion drawing. To ensure data validity, data triangulation techniques were used. The results of the study indicate that the problems are divided into two main aspects: (1) learning-related problems, including the gap between memorization of grammatical rules and their application (i‘rab), high levels of academic anxiety, and decreased classroom concentration; and (2) contributing factors, including methodological factors, linguistic-psychological factors, and classroom management factors. The researcher suggests that teachers adopt more interactive teaching methods and media, as well as innovative visual tools to reduce the abstract nature of Nahwu materials and enhance students’ functional understanding. Additionally, activating “Halaqah Nahwiyyah” (grammar study circles) in dormitories is recommended to overcome psychological barriers and improve students’ linguistic confidence.

Sea Surface Temperature (SST) is an important parameter in oceanographic studies because it influences climate dynamics, ocean circulation, and marine ecosystems. Continuous monitoring of SST in open sea areas requires a reliable system capable of operating autonomously. This study develops a solar-powered ocean buoy designed to measure sea surface temperature while simultaneously evaluating the performance of a solar panel as the main energy source. The system uses a DS18B20 sensor to measure SST and an INA219 sensor to monitor the voltage, current, and power of the solar panel, while an ESP32 microcontroller functions as the central data processing unit. The results show that sea surface temperature tends to remain relatively stable with small daily variations, whereas the temperature and performance of the solar panel exhibit larger fluctuations due to direct exposure to solar radiation and changing weather conditions. Solar panel performance also shows significant variations in current and power depending on the intensity of sunlight. To analyze the influence of SST variations on solar panel performance, a statistical analysis using Analysis of Variance (ANOVA) was conducted. The ANOVA results, based on the calculated F-value and the significance value (p-value) at a confidence level of α = 0.05, indicate that SST variations have a significant effect on solar panel performance, demonstrating that the proposed solar-powered buoy system can operate autonomously and has potential for long-term SST monitoring in offshore areas.

The rapid development of the Industrial Revolution (IR) 4.0  and the transition towards Society 5.0 demand an increase in digital literacy and a basic understanding of technology systems starting from secondary education. The Community Service (CS) Program conducted by the Department of Electrical Engineering Universitas Presiden aims to introduce the concepts of logic gates and digital systems to students of SMA 1 Cikarang Pusat. This CS integrates theoretical explanations and simulation practice using the online platform Circuitverse. This CS was evaluated using a Likert scale (1–4) questionnaire instrument, namely Expectation (Importance) and Performance, with a total of 40 student respondents. The analysis results show that all indicators received an average performance score above 3.30, with satisfaction indices ranging from 82.50% to 90.62%, which falls into the very high category. The indicator for the use of appropriate technology received the highest score of 90.62%, indicating the relevance of the material to current technological developments. The Importance–Performance Analysis (IPA) shows that most indicators are in the 'maintain performance' quadrant, indicating alignment between participants' expectations and the activity's performance. These findings suggest that the workshop is effective in enhancing students' understanding of basic digital system concepts while also fostering interest in engineering and technology fields. The activity underscores the strategic role of universities in bridging the technology literacy gap at the secondary education level in response to the challenges of the IR4.0 and Society 5.0.

This study contributes to the development of cultural-based SME studies by positioning digitalization and sustainability as key foundations for strengthening local economic performance.

Floods are the most frequent hydrometeorological disasters in Indonesia and significantly contribute to increased trauma cases and disruption of healthcare services, particularly in vulnerable regions such as Aceh Province. These conditions are exacerbated by limited resources, damaged health facilities, and restricted access to referral centers. This study aims to examine the implementation of early emergency surgical management during flood disasters based on damage control surgery principles and international guidelines. A descriptive qualitative approach was employed through a literature review combined with field observations conducted during the emergency response phase of flood disasters in Bireuen Regency. Data were collected from direct clinical observations, brief interviews with healthcare providers, and documentation of trauma cases requiring early surgical intervention. The results indicate that effective patient stabilization can be achieved despite limited resources through airway, breathing, and circulation (ABC) management, hemorrhage control, wound irrigation, and fracture immobilization using simple and improvised equipment. Approximately 90% of patients were successfully stabilized prior to referral to definitive healthcare facilities. In conclusion, adaptive and timely application of damage control surgery principles plays a crucial role in saving lives and strengthening emergency surgical response during flood disasters.
