This study evaluates the consistency of transmitter level performance through calibration data obtained from the Instrumentation Maintenance Unit of the Cilegon PLTGU. The purpose of this study is to determine the accuracy, linearity, and stability of transmitter output against standard reference values. Qualitative methods were used, including direct observation, interviews, and literature studies to support the analysis of calibration procedures. Calibration data from the Masoneilan 12420-51 and Yokogawa EJA210E transmitters were analyzed using a comparative approach between normal and abnormal calibration results. Classification was based on the difference between the actual output and the 4–20 mA standard signal, with a tolerance limit of ±0.25% in accordance with ISA and IEC calibration standards. The results of the study show that the Level-3 Deaerator Storage Tank transmitter operates within the normal range, with excellent linearity and accuracy, while the Flash ST Tank Level transmitter shows minor deviations outside the tolerance limit, categorized as abnormal. These deviations suggest the potential for drift or zero shift influenced by environmental factors and aging. This study concludes that periodic calibration is necessary to maintain tranmitter performance reliability and ensure accurate signal transmission in the automatic control system at the Cilegon PLTGU facility.

The Gas and Steam Power Plant (PLTGU) utilizes exhaust heat from gas turbines to produce steam, which is then used to drive steam turbines. One of the critical processes in this system is seawater desalination, which requires reliable measuring instruments to ensure the continuity and quality of the water supply. The Differential Pressure Flow Transmitter type Azbil JTD920S is used to measure fluid flow rates at four main points: Sea Water Flow (feed), Distillate Water Flow, Condensate Water Flow, and Sea Water to Ejector Condenser Flow. A decline in transmitter performance may occur due to environmental factors, corrosion, and high workload, making periodic preventive maintenance (PM) essential. This study aims to analyze the transmitter’s performance by comparing PM data with the manufacturer’s maximum specifications using literature studies, direct observation, and interviews. The calculation results show that the highest performance levels are found in the Distillate Water Flow (73.53%) and Sea Water to Ejector Condenser Flow (73.87%) lines, while the lowest is in the Condensate Water Flow (49.00%). These findings emphasize the importance of close monitoring of high-performance transmitters to prevent premature failure and maintain the efficiency of the desalination process.

This study aims to analyze the narrative dissonance in the corporate communication of the Aqua brand, especially in the context of the crisis of meaning that arises between claims of natural purity and technical findings related to the use of borewells in the production process. Using a qualitative approach through content and narrative analysis, the study integrates two main theoretical frameworks: the Narrative Paradigm (Fisher, 1984) and Image Repair Theory (Benoit, 1995). The analysis focused on how companies are building, maintaining, and renegotiating their corporate narrative amid public pressure and consumer expectations. The results show that the legitimacy crisis arises due to the symbolic mismatch between the narrative of "purity" communicated and the operational reality revealed to the public. This tension triggered a strategic response from the company in the form of public clarification, transparency of the production process, and repositioning of messages to restore consumer image and trust. This study confirms the importance of narrative coherence and reflexivity in corporate communications, especially in an era of digital openness that demands accountability and consistency between symbolic messages and tangible practices. These findings contribute to the study of crisis communication and brand image restoration strategies, as well as a reference for companies in designing ethical, transparent, and sustainable communication to maintain legitimacy and credibility in the eyes of the public.

Technological advancements in education have led to major transformations, particularly with the implementation of the Merdeka Curriculum, which emphasizes learning flexibility, student-centered approaches, and educator autonomy in developing innovative teaching methods. One of its essential aspects is the integration of technology for managing educational data, including student health records. At SMP IT Mutia Rahma, biannual student health monitoring has generated a growing volume of data, making it difficult to identify students experiencing psychological challenges. Adolescent mental health problems—such as learning stress, anxiety, and social pressure—can negatively affect academic performance if left unaddressed. This study aims to group students based on their mental health conditions to support more effective intervention strategies. The K-Means Algorithm, a data mining technique for clustering data by similarity, was employed to analyze student health data. The results show that in a three-cluster model, Cluster 2 represents students in a stable condition characterized by high resilience and low counseling needs, indicating good mental health and academic engagement. Meanwhile, Clusters 1 and 3 include students requiring further attention and support. This research demonstrates that the K-Means Algorithm can serve as an effective tool in identifying and categorizing student mental health conditions to improve school-based health management and early intervention programs.

This study aims to examine the effect of using the Survey, Question, Read, Recite, Review (SQ3R) method assisted by digital story texts on students' critical thinking skills in the material "Book of the Window World" of grade V of SD Negeri 104202 Bandar Setia. The background of this study is based on the low critical thinking skills of students due to the dominance of conventional methods that are less varied and minimal use of learning media, especially in Indonesian subjects. This study uses a quantitative approach with a quasi-experimental method and a Nonrandomized Pretest-Posttest Control Group Design. The research subjects consisted of class VA (experimental, n = 22) who received learning with the SQ3R method assisted by digital story texts, and class VB (control, n = 23) who received conventional learning. The pretest results showed that students' initial critical thinking skills were in the moderate category (experimental x ̄ = 67.23; control x ̄ = 51.96). After the treatment, the experimental class' posttest average increased significantly to 82.41, or 15.18 points, while the control class did not experience any significant improvement. A t-test demonstrated a significant difference between the two groups (t count > t table). The study's conclusions indicate that the SQ3R method, aided by digital narrative texts, significantly improved students' critical thinking skills compared to conventional methods.

University students frequently face various academic demands, such as coursework, research, field practice, and examinations. These pressures may lead to psychological stress that can trigger anxiety. If not properly managed, anxiety can negatively affect academic performance, social interactions, and students’ psychological well-being. The aim of this study was to examine the relationship between the intensity of Qur’an recitation and the level of anxiety among students. This research employed a quantitative descriptive design involving 103 students from the Department of Psychology, Padang State University as participants. The sampling technique used was nonprobability sampling with a purposive sampling approach. The instruments consisted of the Qur’an Reading Intensity Scale adapted from Pradika (2014) with a reliability coefficient of 0.721, and the Zung Self-Rating Anxiety Scale with a reliability coefficient of 0.829. Data were analyzed using Pearson’s product-moment correlation test. The findings revealed a significant negative correlation between the intensity of Qur’an recitation and students’ anxiety levels (r = -0.801; p = 0.000 < 0.05). This indicates that the more frequently students read the Qur’an, the lower their anxiety levels, and vice versa. Categorization results further showed that most students had a high intensity of Qur’an recitation (42.7%) and experienced low to moderate levels of anxiety (78.7%). These results reinforce previous studies suggesting that spiritual practices such as Qur’an recitation can serve as an effective spiritual coping strategy to foster tranquility, regulate emotions, and strengthen resilience in facing academic stressors. Therefore, Qur’an recitation can be recommended as a complementary approach to maintaining students’ mental health in higher education settings.
