Aggressive behavior is one of the manifestations commonly found in individuals with mental disorders, and this can potentially cause harm both to themselves and to their surroundings. To address this condition, one non-pharmacological approach that can be implemented is the use of Mozart classical music therapy. This study aims to evaluate the impact of Mozart classical music therapy on patients who have the potential to exhibit violent behavior at Aceh Mental Hospital. The research activities were conducted from July 2 to 5, 2025. The research design adopted in this study is pre-experimental using the One group pretest-posttest Design method. The study subjects consisted of 15 inpatients who had been identified as being at risk for violent behavior, with sample selection carried out through purposive sampling. The findings of the study showed that the average score of signs and symptoms before the intervention was 5.73, with a score range of 3 to 8. After the intervention in the form of Mozart classical music therapy, the average score of signs and symptoms decreased significantly to 1.60, with a range between 1 and 2. Statistical analysis using the Wilcoxon Signed Rank test showed a Z value of -3.437 with a significance level of P = 0.000 (P < 0.05). Based on these results, it can be concluded that Mozart classical music therapy has a significant effect in reducing the risk of violent behavior in patients. Therefore, Mozart classical music therapy is recommended as an effective supportive intervention and can be routinely integrated into psychiatric care rooms.

Ankle sprain is one of the most common musculoskeletal injuries in sports activities and often results in pain, limited range of motion, muscle weakness, and decreased functional ability. Appropriate physiotherapy management is essential to accelerate recovery and restore ankle function.

Spinal anesthesia is one of the regional anesthesia methods that is often chosen in various surgical procedures, especially in the area of the lower extremities, pelvis, and lower abdomen. The most common complication encountered in this technique is the occurrence of hypotension, which can affect tissue perfusion and hemodynamic stability of the patient. This study aims to examine the incidence of hypotension in spinal anesthesia, including mechanisms, risk factors, and management. The method used in this study is literature review with a scientific source search process conducted through various databases PUBMED, Sciencedirect, Researchgate, and Google Scholar with a publication year range of 2016 to 2026. The results showed that hypotension arises as a consequence of an obstacle in the sympathetic nervous system, which provokes dilation of blood vessels as well as reduced venous return. Risk factors include age, body mass index, patient position, block height, duration of surgery, fluid status, Injection Point, and type of anesthetic drug used. Management is carried out by administering fluids, vasopressors, as well as strict hemodynamic monitoring. A good understanding of the risk factors and mechanisms of hypotension is expected to improve patient safety during spinal anesthesia..

The transportation of tiger shrimp postlarvae (Penaeus monodon) in aquaculture practice is a critical stage as it may induce physiological stress that directly reduces survival rate. Salinity, as a water quality parameter closely associated with osmoregulatory processes, is a key determinant of success in closed wet system transportation. The present study was designed to examine how varying salinity concentrations influence the survival percentage of PL 10 tiger shrimp postlarvae subjected to closed wet transport conditions, as well as to identify the most suitable salinity range for such transport. A Completely Randomized Design (CRD) was employed with five salinity levels as treatments — 10, 15, 20, 25, and 30 ppt — each replicated five times. Each experimental unit contained 1,500 postlarvae in 1 L of oxygenated water packed in plastic bags and transported for approximately 3 hours. The main parameter observed was survival rate (SR), while supporting parameters included temperature, dissolved oxygen (DO), and pH. Statistical evaluation included the Kolmogorov–Smirnov normality test, Levene’s test for variance homogeneity, one-way analysis of variance (ANOVA), and Duncan’s Multiple Range Test (DMRT) at a significance level of α = 0.05. Results showed that salinity differences had a highly significant effect on postlarvae survival rate (Sig. = 0.000 < 0.05). The 25 ppt salinity treatment produced the highest survival rate of 99.64%, while 10 ppt resulted in the lowest at 63.78%. The measured water quality variables — temperature, dissolved oxygen, and pH — did not exert a statistically significant effect on postlarvae survival throughout the transport period.

The cosmetic industry continues to grow rapidly along with the increasing demand for natural-based body care products, one of which is massage oil. Essential oils such as lavender, citronella, and chamomile are known to have synergistic effects as relaxation agents, anxiety reducers, and anti-inflammatory agents. To support the safety and effectiveness of their use, the selection of appropriate carrier oils, such as olive oil, almond oil, and virgin coconut oil (VCO), is required due to their good penetration ability and moisturizing properties. This study aimed to determine the effect of variations in carrier oils on the physical and sensory characteristics of aromatherapy massage oil preparations and to identify the most optimal formulation. The research was conducted experimentally by formulating three massage oil formulations using a combination of lavender, citronella, and chamomile essential oils with different carrier oil compositions. The evaluations included organoleptic tests, pH, viscosity, specific gravity, stability, irritation tests, and hedonic tests. The results showed that all formulations were liquid, homogeneous, stable for 28 days, had pH values within the normal skin pH range, met the required viscosity and specific gravity standards, and did not cause skin irritation. Based on the hedonic test, formulation F2 was the most preferred by respondents and was determined to be the best formulation due to its most favorable aroma, texture, and comfort during use. Therefore, variations in carrier oils influence the characteristics of massage oil preparations and enable the determination of the optimal formulation

Achilles tendon rupture is a common lower extremity injury that significantly affects functional mobility and gait performance. Post-operative patients frequently experience pain, edema, limited range of motion (ROM), muscle weakness, and impaired ambulation. Physiotherapy rehabilitation plays a crucial role in restoring tissue integrity and functional capacity. This case study aimed to analyze the effectiveness of combined electrotherapy modalities and therapeutic exercises in a post-operative left Achilles tendon rupture patient. The intervention included ultrasound therapy, Transcutaneous Electrical Nerve Stimulation (TENS), infrared therapy, dry needling combined with Percutaneous Electrical Nerve Stimulation (PENS), and progressive therapeutic exercises such as isometric training and calf raises. Clinical outcomes were evaluated through ROM measurement, Manual Muscle Testing (MMT), edema observation, and gait analysis across four therapy sessions. Results demonstrated gradual improvement in dorsiflexion and plantarflexion ROM, reduction of edema, increased gastrocnemius-soleus muscle strength, and restoration of independent ambulation without assistive devices. The multimodal physiotherapy approach appears to support tendon healing, enhance neuromuscular activation, and accelerate functional recovery during the subacute post-operative phase.

Acid mine drainage (AMD) is characterized by low pH and high concentrations of heavy metals such as iron (Fe) and manganese (Mn) that exceed environmental quality standards, thus requiring effective treatment to prevent environmental pollution. This study aims to evaluate the ability of a mixture of activated carbon derived from pineapple leaves mixed with coal to increase pH and reduce Fe, Mn, and Total Suspended Solids (TSS) levels in acid mine drainage at PT Alreksa Bara Mitra. The process to make activated carbon involved preparation, carbonization, and activation processes on the pineapple leaves and coal separately. The following step is to mix but pineapple leaves and coal the has been activated. The treatment was conducted using an adsorption method with variations in adsorbent mass of 4 g, 8 g, and 12 g and a contact time of 30 minutes. The parameters analyzed included pH, Fe, Mn, and TSS before and after treatment, and the results were compared with the quality standards stipulated in Minister of Environment and Forestry Regulation No. 05/2022. The results showed that the characteristics of the activated carbon mixture met the SNI 06-3730-1995 standard. Increasing the adsorbent mass contributed to the rise in pH from 5.5 to near the acceptable range of 6–9 and significantly reduced Fe, Mn, and TSS concentrations below the permitted limits.The findings indicate that the mixture of pineapple leaf- and coal-based activated carbon is an effective, economical, and environmentally friendly alternative adsorbent for acid mine drainage treatment.

Developmental Dysplasia of the Hip (DDH) in children often results in joint stiffness, muscle weakness, limited range of motion, and gait impairment following surgical management and immobilization. Early physiotherapy intervention is essential to restore hip function and walking ability. This study aimed to evaluate the effectiveness of active exercise on functional walking in outpatient children aged 3–5 years after DDH surgery. A case study design was conducted on three female patients who completed a five-week rehabilitation program consisting of ten active exercise sessions, including hip strengthening, mobility training, and balance exercises, combined with a home program. Outcome measures included hip range of motion, Manual Muscle Testing, and Modified McKay and Harris Hip Score assessed at baseline, mid-intervention, and post-intervention. The results showed improvements in hip range of motion, particularly in flexion, extension, abduction, adduction, and external rotation, while internal rotation improved but did not reach normal values. Muscle strength increased from grade 1–2 to grade 3 in most hip muscle groups. Functional walking scores improved from poor to good and excellent, with patients achieving independent, symmetrical gait without pain. These findings indicate that active exercise is an effective rehabilitation approach to reduce impairments and enhance functional walking in children after DDH surgery. The study highlights the importance of structured physiotherapy and caregiver involvement to optimize recovery and participation in daily activities.

This meta-analytic study aims to comprehensively examine the relationship between mental health, learning capacity among health education students, and competencies in nosocomial disease risk management through cross-contextual empirical synthesis. An analysis of 47 studies involving 12,847 participants from 15 countries demonstrates a strong, statistically significant association between students' mental health and competencies in nosocomial infection prevention, as reflected by a correlation coefficient of r=0.68 (p<0.001) and a 95% confidence interval of 0.61-0.74. Students with high mental health scores (M=78.4; SD=8.2) exhibited substantially superior understanding of infection prevention protocols, namely 43% higher than the control group (M=54.7; SD=12.1; t(846)=18.42; p<0.001; d=2.31). Structural equation modeling confirmed learning capacity as a significant partial mediator (β=0.52; p<0.001), with an indirect effect reaching 35.4% and a 95% CI range of 28.6-42.1%. Mindfulness-based psychoeducational interventions were shown to enhance nosocomial risk identification abilities by 38.7% (F(2,564)=42.18; p<0.001; η²=0.41) while reducing clinical anxiety by 31.2% (t(382)=9.84; p<0.001). These findings extend the frameworks proposed by Song (2024) and Schutte et al. (2025), which primarily emphasize cognitive aspects, by demonstrating that the integration of psychological dimensions yields a multidimensional predictive model explaining 64.3% of the variance in risk management competence (R²=0.643; F(5,841)=304.76; p<0.001), surpassing conventional models that account for only 38-45% of the variance.

Knee osteoarthritis (OA) is a degenerative joint disorder frequently affecting older adults, characterized by symptoms such as pain, stiffness, and reduced physical capability. These symptoms can lead to decreased independence and a lower quality of life among the elderly. Tai Chi exercise is recognized as one of the recommended non-pharmacological approaches for managing osteoarthritis. This paper aims to explore the effects of Tai Chi exercise on alleviating knee pain in older adults with osteoarthritis. The methods applied include a literature review, a Pre-test Post-test design, and theoretical nursing care analysis using a community nursing framework. Pain intensity was measured using the Numeric Rating Scale (NRS). The Tai Chi program was conducted three times per week, with each session lasting 20–30 minutes. Findings show that Tai Chi exercise helps reduce knee pain intensity, enhances joint range of motion, strengthens muscles, and improves balance and physical mobility in the elderly. Furthermore, Tai Chi promotes relaxation, which aids in pain management by decreasing stress responses and increasing endorphin release. Overall, the study concludes that Tai Chi exercise is an effective non-pharmacological nursing intervention for managing knee pain in older adults with osteoarthritis and holds potential for incorporation into elderly healthcare programs.

Limited access to adequate housing remains a major challenge for low-income households in Indonesia, including in Banyumas Regency. The subsidized housing program has been implemented as a public policy instrument to improve housing affordability while enhancing social and economic welfare. This study aims to analyze the role of subsidized housing in improving housing access and the economic conditions of low-income communities in Banyumas Regency. The research adopts a qualitative approach using a documentation study method by collecting and analyzing policy documents, official government reports, scholarly journal articles, and relevant publications related to subsidized housing and the socio-economic conditions of low-income households. Data analysis was conducted through content analysis to interpret the role of subsidized housing based on indicators of housing affordability and household economic impacts. The findings indicate that subsidized housing significantly reduces the housing cost burden of low-income households from levels exceeding the affordability threshold to a more economically manageable range. The reduction in housing expenditure contributes positively to household economic stability by allowing savings and reallocation of income toward productive needs such as education, healthcare, and financial security. However, the effectiveness of subsidized housing in improving economic outcomes is still influenced by location and accessibility of housing areas. This study concludes that subsidized housing plays a crucial role in expanding housing access and improving the economic conditions of low-income communities, while requiring integrated and sustainable policy support to maximize its long-term benefits.

This study aims to analyze the quality of granulated sugar products at PT Madukismo Yogyakarta using the Six Sigma methodology through the DMAIC approach (Define, Measure, Analyze, Improve, and Control). The main problems identified involve high variations in product quality and significant defects, particularly related to moisture content (less dry) and off-color products. Production and defect data from May 2023 to September 2024 were used to calculate DPMO and sigma levels as indicators of process performance. The results show that the sigma level ranges from 4.48 to 5.03, with the highest DPMO recorded at 1,456.76 and the lowest at 205.55, indicating that the process has not yet achieved Six Sigma performance. Pareto analysis reveals that color defects (58.4%) contribute the most to overall defects. The Fishbone diagram analysis indicates that defect causes originate from factors related to manpower, method, material, machine, measurement, and environment. Improvement recommendations include digitalizing monitoring systems, enhancing SOPs, upgrading operator competencies, modernizing machinery, improving raw material management, and strengthening environmental control systems. These improvements are expected to reduce DPMO to below 500 and increase the sigma level to at least 5.2. This study concludes that the Six Sigma approach is effective in identifying quality issues and formulating strategies to improve the quality of granulated sugar products at PT Madukismo.

In high-performance computing (HPC) environments, the need to balance memory efficiency and query performance is crucial for ensuring optimal system performance. Traditional data structures, such as B-trees and hash tables, often prioritize either memory usage or query speed, leading to suboptimal performance in memory-constrained systems. This paper proposes a hybrid data structure that combines the strengths of multiple traditional data structures to optimize both memory usage and query processing speed. The proposed hybrid structure integrates cache-conscious algorithms, dynamic memory allocation, and compression techniques for intermediate query results. The approach is evaluated through extensive benchmarking tests comparing it to standard data structures like B-trees and hash tables under various workloads. Results show that the hybrid data structure reduces memory overhead by up to 30% while maintaining query processing speeds up to 1.5 times faster than conventional methods. Furthermore, the hybrid structure demonstrates robust performance across different types of queries, including both point and range queries, ensuring versatility and efficiency. The findings indicate that this hybrid approach provides a promising solution for HPC systems, where both memory efficiency and query speed are essential. Future research can explore extending the hybrid structure to distributed systems and emerging technologies, further improving its scalability and adaptability to new computational paradigms.

Highways play a strategic role in supporting economic development, so the quality of pavement materials (flexible pavement) must meet previously established quality standards. The Asphalt Concrete Wearing Course (AC-WC) layer, as the topmost layer of flexible pavement, is susceptible to damage caused by aging triggered by environmental conditions, particularly ambient temperature. Temperatures above 30°C are known to accelerate plastic deformation (rutting) and reduce pavement bearing capacity. The Meteorology, Climatology, and Geophysics Agency indicates that temperatures in Lhokseumawe City, North Aceh, range from 33.7–35.3°C with day-night fluctuations that could potentially accelerate the degradation of mechanical properties. This study aims to analyze the Marshall characteristics of AC-WC asphalt mixtures under ambient temperature conditions. The testing was conducted with varying exposure times of 0, 15, 30, 45, 60, 75, and 90 days at a minimum temperature of 23.90°C and a maximum temperature of 31.80°C, with an average humidity of 87.93%. The test results showed that the AC-WC asphalt mixture experienced a decrease in stability value of 21.37% and an increase in flow value of 36.36%, resulting in a decrease in the Marshall Quotient (MQ) value of 42.52%.

Catfish farming is one of the fisheries areas with great potential in Indonesia. However, the problem of feed efficiency, use of probiotics, and air temperature control are still the main obstacles that affect the health and growth of fish. This study aims to design and implement an automatic system that can regulate the provision of feed and probiotics and control and control air temperature directly using the ESP32 microcontroller. This system has several important components, such as the ESP32 microcontroller as a control center, servo motors for feed and probiotic distribution, and DS18B20 temperature sensors to monitor air temperature. All components can be controlled and viewed through an IoT-based application with a Wi-Fi connection or applications such as Telegram. This trial aims to determine whether this system can provide feed and probiotics according to the specified time, and maintain air temperature in the optimal range (28°C–40°C) for catfish growth. In this way, the system is expected to increase efficiency in catfish farming automatically, reduce the need for human labor, and minimize errors in pond management.

Engine performance is a critical parameter in automotive engineering as it directly affects power output, torque characteristics, and overall vehicle efficiency. One of the components that significantly influences engine performance is the exhaust system, which regulates exhaust gas flow and back pressure. This study aims to experimentally analyze the effect of replacing a standard exhaust system with an aftermarket exhaust system on the performance of a 2NR-VE engine. The research employed an experimental method using a comparative design with two testing conditions: a factory-standard exhaust system and an aftermarket exhaust system. Engine performance testing was conducted using a dynamometer (dyno test) to measure horsepower and torque across various engine speed ranges (RPM). Each testing condition was performed repeatedly, and the resulting data were averaged to reduce measurement errors and minimize the influence of operational fluctuations. The experimental results indicate that the aftermarket exhaust system significantly improves engine performance. The maximum power increased from 82.5 HP to 91.6 HP, while the maximum torque rose from 131.2 Nm to 154.4 Nm. These improvements suggest that the aftermarket exhaust configuration effectively reduces exhaust back pressure and enhances exhaust gas flow efficiency. Therefore, replacing the exhaust system can be considered an effective approach to improving engine performance, provided that the modification is technically appropriate and complies with applicable emission and noise regulations.

Chronic kidney disease (CKD) is a growing global health concern that frequently remains undiagnosed until advanced stages. Early detection through simple laboratory screening is essential to prevent disease progression and associated cardiometabolic complications. This community service program aimed to assess kidney function using serum creatinine and estimated glomerular filtration rate (eGFR), while increasing public awareness regarding CKD prevention. A total of 59 participants were included, with a mean age of 39.15 ± 15.39 years (range 16–75 years), predominantly female (74.58%). The mean serum creatinine level was 1.0 ± 0.19 mg/dL, and the mean eGFR was 91.08 ± 20.53 mL/min/1.73 m². Most participants demonstrated normal kidney function (28.8%) or mild decline (21.6%). A progressive reduction in eGFR with increasing age was observed, reflecting the physiological decline in nephron mass and renal perfusion. The program also provided education on kidney-protective practices, including optimal blood pressure control, diabetes management, adequate hydration, and avoidance of nephrotoxic agents. This intervention improved participants’ understanding of CKD risk factors and the importance of regular screening. In conclusion, serum creatinine and eGFR evaluation offer simple, accurate, and practical tools for early CKD detection, supporting promotive–preventive strategies to slow disease progression and enhance quality of life in at-risk populations.
