Blasting is a critical method for overburden removal in open-pit coal mines, where fragmentation quality directly impacts loading efficiency and operational costs. This study aims to analyze the actual fragmentation resulting from overburden blasting at Pit 4 Middle of PT. Victor Dua Tiga Mega, Central Kalimantan, to predict fragmentation using the Kuz-Ram model, and to evaluate the conformity of both results against the company standard (boulder size ≤144.6 cm or ≥50 cm for analysis). The research employed a quantitative comparative method. Primary data included blasting geometry and photographs of muck piles from 10 blasting events, which were analyzed using WipFrag software to obtain actual fragmentation distribution. Secondary data comprised rock characteristics and explosive properties for Kuz-Ram prediction input. The results showed significant variation in actual boulder percentage (≥50 cm), ranging from 6.19% to 32.91% with an average of 16.05% (medium category). Statistical analysis revealed a very weak negative correlation (r = -0.21) between powder factor (PF) and boulder percentage, indicating that PF is not the dominant factor within the consistent application range (0.21-0.23 kg/bcm). Comparison with Kuz-Ram predictions showed that the model consistently over-predicted coarse material, with an average difference of +25.21%, suggesting the need for rock factor (A) recalibration. It is concluded that the blasting results are inconsistent, strongly influenced by uncontrollable factors such as geological conditions. Recommendations include geometri evaluation, particularly burden and spacing, and calibration of the Kuz-Ram model for more accurate future predictions.

The global ecological crisis is not only a scientific issue but also reflects the decline of human moral and spiritual awareness toward nature. This study aims to examine the acculturation approach of Islam Nusantara in Islamic Religious Education (PAI) learning as an effort to foster students’ ecological awareness. The research employed a qualitative library research method using various relevant sources, including books, national and international journal articles, and educational policy documents. Data analysis was conducted through data reduction, thematic presentation, and interpretive-analytical conclusion drawing. The findings indicate that Islam Nusantara, as a product of the acculturation between universal Islamic values and local Nusantara wisdom, contains various ecological traditions such as sasi, subak, and hutan larangan (forbidden forests), which can be contextually integrated into PAI learning. The developed learning model includes the use of local wisdom as learning resources, participatory project-based learning methods, and thematic Qur’anic interpretation related to environmental issues. The ecotheological approach of Islam Nusantara is considered effective in connecting religious teachings with students’ ecological realities, thereby fostering a religious-ecological character that views environmental preservation as part of worship. Although challenges remain in theological, pedagogical, and institutional aspects, this approach contributes strategically to shaping environmentally responsible Muslim generations.

This research is motivated by the phenomenon of high academic pressure among students who possess excessively high self-standards or perfectionistic personality traits. The primary issue examined is how these students manage their emotions amidst a constant fear of failure. This study aims to gain a profound understanding of the emotion regulation strategies employed by perfectionistic students. The research method used is qualitative with a phenomenological approach to explore the participants 3 subjective experiences. Data were collected through in-depth interviews with active students selected via purposive sampling. The results indicate that participants tend to use maladaptive strategies, such as expressive suppression and procrastination, when they feel unable to achieve maximum targets. Social support and emotional maturity were identified as key factors helping them transition toward adaptive strategies. The study concludes with an emphasis on the necessity of specialized psychological support for perfectionistic students to develop self-compassion.

This research aims to analyze the legal protection of workers' rights during Termination of Employment (PHK) due to company bankruptcy, as well as assessing the conformity between applicable legal provisions and practice in the field. The method used is normative legal research with a statutory and factual approach. The research examines various legal regulations related to employment and bankruptcy, as well as the implementation of these regulations in resolving employment disputes. The research results show that the regulation of layoffs according to Law Number 6 of 2023 concerning Job Creation emphasizes that layoffs are the termination of the employment relationship due to certain things which result in the end of the rights and obligations between workers and employers which is a last resort. In practice, however, workers often experience difficulties in obtaining their normative rights, especially when companies face financial instability or insolvency. Then the responsibilities that can be carried out by companies to realize fair legal protection for workers are divided into 2 (two) efforts, namely preventive and repressive. Preventive efforts include compliance with labor regulations and transparent communication, while repressive efforts are carried out through dispute settlement and fulfillment of workers’ compensation rights. This research confirms the existence of a gap between legal norms and practice in the field. Therefore, it is necessary to increase legal awareness and strengthen regulatory enforcement to ensure the fulfillment of the rights of workers affected by layoffs.

Strengthening scientific literacy in elementary science learning requires interactive and contextual instructional strategies. Game-based learning has been shown to enhance student motivation and engagement (Clark et al., 2016). This study aims to develop and examine the effectiveness of an interactive quiz-based educational game on the topic of food chains and ecosystems for fifth-grade students. The research employed a Research and Development approach using the ADDIE model, consisting of analysis, design, development, implementation, and evaluation stages (Yusuf & Rahman, 2023). The participants were 25 students. Data were collected through pretest and posttest instruments and analyzed using the N-Gain formula to measure learning improvement. The findings indicate a moderate to high increase in students’ learning outcomes after the implementation of the developed media. In addition, students demonstrated greater participation during the learning process. These results suggest that interactive quiz-based educational games can serve as an effective alternative strategy to enhance conceptual understanding in elementary science education.

Public facility cleanliness is a reflection of cultural values and collective social responsibility. Bus stops, as daily transit points for thousands of commuters, often face declining cleanliness due to limited user participation and management. This community service program was conducted on April 22, 2026, at RSAL Bus Stop, Surabaya, Indonesia, with one researcher as the sole implementer. The objectives were to improve physical cleanliness, provide environmental education, and enhance aesthetics through greening. The method consisted of three activities: installing cleanliness reminder posters, cleaning the bus stop area, and adding ornamental plants in flower pots. Evaluation employed qualitative descriptive techniques, including observation, photographic documentation, and informal interviews. Findings revealed that the bus stop floor, initially littered with plastic waste, cigarette butts, and dry leaves, became clean after sweeping. Posters were successfully placed in visible positions, and three flower pots containing Sansevieria trifasciata and Epipremnum aureum created a fresher atmosphere. Users responded positively, noting improved comfort and cleanliness. The synthesis indicates that simple interventions by a single individual can generate meaningful improvements when combining physical cleaning, visual education, and greening. This initiative demonstrates that small-scale university-led social responsibility programs can serve as replicable models for sustainable public facility management.

This study examines the effect of capital structure, dividend policy, and firm size on firm value at PT Adhi Karya (Persero) Tbk during the period 2014–2024. The company’s firm value has shown fluctuations and a declining trend despite an increase in total assets, indicating a mismatch between asset growth and market perception. This study aims to analyze the influence of internal financial factors on firm value, both partially and simultaneously. A quantitative approach is employed using secondary data obtained from the company’s annual financial statements. Capital structure is measured using the Debt to Equity Ratio (DER), dividend policy using the Dividend Payout Ratio (DPR), firm size using the natural logarithm of total assets, and firm value using Tobin’s Q. Data are analyzed using multiple linear regression with the assistance of SPSS, supported by classical assumption tests, t-test, F-test, and coefficient of determination (R²). The results show that partially, capital structure and dividend policy do not have a significant effect on firm value, while firm size has a significant effect. Simultaneously, all independent variables have a significant effect on firm value. The findings indicate that firm size plays a dominant role, while other factors may also influence firm value beyond the model.

This study aims to analyze the role of liturgical inculturation in shaping the faith experience of the congregation through the practice of Inculturated Mass at St. Klemens Mandonga Parish. The study employed a descriptive qualitative approach combined with literature review and a survey involving 96 parish respondents.

The rapid digital transformation in educational institutions demands an efficient student grade data processing system capable of handling workloads responsively. This study aims to analyze and compare the efficiency of sorting algorithms (Merge Sort and Quick Sort) and searching algorithms (Linear Search and Binary Search) on a web-based platform. The research method employed is laboratory experimental, testing algorithm performance across various data volume stratifications, ranging from 50 to 1000 entities, using the V8 JavaScript engine. Research findings indicate that Quick Sort possesses superior speed compared to Merge Sort due to its efficient in-place sorting architecture, which minimizes memory overhead and Garbage Collection activity. Furthermore, a performance anomaly was discovered where the Just-In-Time (JIT) Compiler mechanism optimizes execution on large data volumes through a warm-up phase. In the searching aspect, Binary Search demonstrates superior O(log n) logarithmic stability compared to Linear Search, which risks causing interface freezing on massive data. The implication of this study is the critical importance of implementing data pre-sorting protocols to exploit logarithmic search speeds to ensure academic information system scalability. The integration of appropriate algorithms proves to be a crucial foundation in maintaining web application responsiveness amidst the ever-increasing escalation of educational data.

This study focuses on the elements of gharar (uncertainty), tadlis (fraud), and breach of contract in examining multiple transactions of a single land object from the standpoint of Islamic economic law. The rising frequency of disagreements over land purchases and sales brought on by the same seller engaging in overlapping transactions, unclear ownership status, and a lack of transparency has prompted this research. This study aims to investigate the effects of these activities on Indonesian positive law and Islamic economic law. This case study employed an empirical legal approach and was carried out in Grogol Village, Tulangan District, Sidoarjo Regency. Data was gathered through observation, interviews, and documentation by the buyer, seller, and local authorities. The findings indicate that due to unclear land boundaries and ownership status, the transaction contained significant elements of gharar and tadlis because the seller concealed important information about the previous transaction. Furthermore, the seller's failure to fulfill obligations stipulated in the contract constitutes a breach of contract under positive law. This study demonstrates that these practices not only violate legal regulations but also contradict the principles of Islamic economic law such as justice, transparency, and good faith. According to this study, legal awareness, administrative accuracy, and institutional oversight are vital to prevent such issues in the future.

Dengue Hemorrhagic Fever (DHF) remains a significant public health problem in tropical countries, including Indonesia. The presence of Aedes aegypti larvae is an important indicator of dengue transmission risk and is influenced by environmental factors, particularly temperature and humidity. This study aimed to analyze the relationship between temperature and humidity and the presence of mosquito larvae in Meteseh Village, Tembalang District, Semarang City. This analytical observational study employed a cross-sectional design involving 100 households selected through quota sampling. Data were collected through direct observation and measurement of temperature and humidity using a thermo-hygrometer, then analyzed using the Chi-square test. The results showed a significant association between temperature and the presence of mosquito larvae (p=0.000), while humidity was not significantly associated with larvae presence (p>0.05). Temperature was identified as a more influential environmental factor in supporting mosquito larvae existence than humidity in the study area. These findings highlight the importance of environmental-based vector control strategies, particularly through management of microhabitat temperature conditions, to support dengue prevention.
