The implementation of Electronic Medical Records (EMR) has become an important element in improving healthcare service quality, efficiency, and patient safety in hospitals. However, the benefits of EMR depend not only on system availability but also on the quality of the information provided and how actively the system is used by healthcare professionals. This study aims to analyze the influence of electronic medical record content and perceived ease of use on the net benefits of EMR, with actual system use acting as an intervening variable. The research applied a quantitative approach with a cross-sectional design conducted at RSM Hospital. The population consisted of all general practitioners and specialist doctors working at the hospital, totaling 51 respondents, and the study used a total sampling technique. Data were collected through structured questionnaires measured using a Likert scale and analyzed using the Structural Equation Modeling–Partial Least Squares (SEM-PLS) method. The results show that EMR content and perceived ease of use significantly influence the net benefits of EMR. Both variables also significantly affect the actual use of the system, while actual use significantly influences the benefits obtained. Furthermore, actual use mediates the relationship between EMR content, ease of use, and net benefits, indicating that better information quality and usability can encourage greater system utilization and maximize the advantages of EMR implementation.

One of the risk impacts of blasting activities is flyrock. The impact of flyrock can be minimized by evaluate the factors that influence flyrock such as blasting geometry. Flyrock cannot be completely eliminated but flyrock distance can be reduced to prevent damage. This study aims to determine the actual maximum flyrock distance in the field and the factors that influence the flyrock distance. This study was conducted at PT. Sims Jaya Kaltim, Paser Regency, East Kalimantan Province. This research was conducted 31 times and the average throwing distance was 79.8 meters, the actual maximum flyrock throwing distance was 134.3 meters and the minimum throw was 40.5 meters. In the flyrock throw prediction, the Richard & Moore calculation method was used with a face burst mechanism of 121.3 meters and cratering of 232.2 meters and the Ebrahim Ghasemi dimensional analysis method of 104.5 meters. From both methods, the Ebrahim Ghasemi method was found to be closest to the actual flyrock with a standard deviation of 29.49 meters and an error percentage of 2.90%. From the results of the correlation between the blasting parameters and the actual flyrock, it was found that the factors that influence the occurrence of flyrock are powder factors, so an analysis was carried out to obtain a maximum flyrock throwing distance of 90 meters so that the safe radius of the tool is 180 meters, then the maximum powder factor used is 0.14 kg/m3.

The increasing integration of internet technology in educational institutions requires structured network governance to ensure that digital resources support academic activities effectively. Unrestricted access to online platforms often leads to non-academic usage such as online gaming and social media engagement during instructional hours, which may reduce learning concentration and degrade network performance. This research develops and evaluates a network access control simulation using a MikroTik RouterBoard RB951Ui-2HnD device. The system applies firewall filtering mechanisms, hotspot-based authentication, and bandwidth allocation strategies through Simple Queue configuration. Network segmentation is implemented to differentiate teacher and student access privileges. The study adopts a Research and Development (R&D) approach to design, configure, test, and evaluate the proposed system. Testing results indicate that the firewall configuration successfully restricts access to selected online games (Mobile Legends, Clash of Clans, Roblox) and social media platforms (YouTube, TikTok, Shopee, Instagram, Telegram). Furthermore, bandwidth management demonstrates effective traffic prioritization, ensuring more stable allocation for teacher accounts in accordance with configured maximum limits. The findings confirm that structured firewall and bandwidth policies can improve network discipline, enhance performance stability, and support a controlled digital learning environment in schools.

This descriptive observational study aims to evaluate the achievement of Minimum Service Standards (MSS) for nutrition at RSUD Dr. H. Slamet Martodirdjo Pamekasan, specifically focusing on the accuracy of diet types, timeliness of food distribution, and patient food waste. Data were collected over a single menu cycle (10 days) from November 24 to December 4, 2025, involving 44 patients per day. Research instruments included observation sheets and the Comstock visual method, with data analyzed based on the Decree of the Minister of Health (Kepmenkes) No. 129 of 2008. The results indicated that the timeliness of food distribution reached 96% and the accuracy of diet types reached 100%, both of which met the MSS requirements (≥ 90% and 100%, respectively). However, the average patient food waste was 25%, which does not yet meet the maximum standard of ≤ 20%. In conclusion, while logistical aspects have fulfilled the established standards, the hospital needs to conduct further evaluations regarding food flavor factors and patients' clinical conditions to reduce food waste in accordance with the applicable standards.

Smoking is the activity of smoking smoke from the burning of tobacco in cigarettes, one end of the cigarette is burned and the smoke can be smoked through the mouth on the other end. If the amount or form of hemoglobin is abnormal, red blood cells cannot function properly in transporting oxygen and carbon dioxide. This can trigger various health problems, including anemia. From the results of this study, we can see that the average value or mean value of hemoglobin levels is 12.5 g/dL, the median value is 12.9 g/dL, the minimum value is 11.9 g/dL, and the maximum value is 16.2 g/dL. The results showed that most of the respondents had hemoglobin levels within normal limits. In detail, hemoglobin levels in the normal category were 23 respondents, low category was 1 respondent, and high category was 1 respondent. This shows that the majority of active smokers in Market VI of North Binjai Village still have normal hemoglobin levels, although smoking has the potential to affect oxygen transport capacity in the long term and increase the risk of health problems if it continues continuously.

Heart disease is the leading cause of death in Indonesia and globally, necessitating an early screening system that is both accurate and clinically trustworthy. Although XGBoost demonstrates high predictive performance, its black-box nature undermines clinical trust, while low recall risks missed diagnosis an unacceptable consequence in population screening, especially in middle-income countries with limited healthcare resources. This study aims to develop a sensitive, transparent, and implementation-ready heart disease screening framework through the integration of SHAP-based Explainable AI. The CDC's Indicators of Heart Disease dataset (319,795 samples) was processed according to WHO/CDC standards, followed by class imbalance handling, hyperparameter optimization using RandomizedSearchCV, evaluation based on metrics sensitive to minority classes (AUC, recall, F1-score, AUC-PR), and threshold tuning to maximize recall. The baseline model showed a very low recall of 12.18%. After optimization and threshold tuning at 0.10, the model achieved recall >96% (96.79%) with a G-mean of 0.7477, supported by SHAP interpretation stability and the ability to capture non-linear interactions between advanced age (AgeCategory_WHO) and poor general health (GenHealth). SHAP analysis confirmed the alignment of dominant features with medical evidence, and its visualizations provide transparent explanations for healthcare professionals indicating its potential implementation as an interpretable clinical decision support system.

Pyrolysis is a biomass conversion method into fuel through heating at high temperatures under oxygen-limited conditions. The main factors influencing the pyrolysis process include temperature, residence time, pressure, particle size, reactor design, and the type of pyrolysis employed.

Introduction: Maximal oxygen volume (VO2max) is the capability of the cardiorespiratory system to deliver oxygen to muscle mitochondria, which is directly proportional to the level of stamina and is obtained from physical activity. Central obesity, which is characterized by excessive accumulation of visceral fat, can cause decreased stamina, so individuals with central obesity tend to have lower VO2max values. VO2max values can be determined by body composition, such as waist circumference, which is an indicator of central obesity. Methods: This study used an observational analytical design with a cross-sectional approach and involved 54 male respondents with high physical activity jobs who worked as building construction workers in Medan City, North Sumatra Province. Waist circumference measurements were carried out using a measuring tape, while VO2max was assessed using a 6-minute walk test. Statistical analysis was performed using the Spearman correlation test with a significance level of 0.05. Results: A total of 47 respondents (87%) had a normal waist circumference, 31 respondents (57.4%) had a fair VO2max, and 16 respondents (29.6%) had an average VO2max. The analysis showed a significant relationship between waist circumference and VO2max, with a P value of 0.000 (P<0.05) and R = -0.658. Conclusion: There is a strong and significant negative correlation between waist circumference and VO2max. This indicates that a larger waist circumference results in a lower VO2max, and a smaller waist circumference results in a higher VO2max.

Breach of contract disputes with small claim values are often hindered by the lengthy and costly conventional litigation process. To address this issue, the Supreme Court issued PERMA No. 2 of 2015, which was later amended by PERMA No. 4 of 2019 concerning Small Claims Court. This study aims to examine the mechanism for resolving breach of contract disputes through small claims and its effectiveness in achieving the principles of fast, simple, and low-cost litigation. This research uses a normative legal method to analyze the relevant legal procedures and regulations. The findings show that small claims court is effective in streamlining the litigation process, with a resolution time limit of a maximum of 25 working days, much faster compared to regular litigation, which can take much longer. However, the implementation of this mechanism is limited by the requirement that evidence must be simple, which can be a challenge in some cases. Thus, small claims court can be an efficient and affordable solution for business disputes with low claim values.

The implementation method involved 20 children selected via purposive sampling, utilizing a one-group pretest-posttest design. The intervention procedure encompassed the presentation of listening strategies, interactive discussions, and structured repetition exercises designed to build phonological automaticity. Quantitative evaluation results indicated a significant improvement, with the participants' mean score rising from 82.9 on the pretest to 86.7 on the posttest, with a maximum achievement score of 94. The discussion reveals that the use of subtitles serves as a visual scaffolding mechanism that facilitates sound-to-form mapping, while repetition drills strengthen the participants' working memory. Overall, the utilization of digital media and repetitive exercises proved effective in lowering cognitive barriers and increasing the participants' active engagement in English language learning.

Coffee husk is an agro-industrial waste with significant potential to be utilized as a renewable energy source through the fast pyrolysis process. This study aims to analyze and optimize gas production from the fast pyrolysis of coffee husk biomass using a screw reactor through single-particle-based Computational Fluid Dynamics (CFD) simulations. The simulations were conducted by varying the operating temperature at 500°C, 600°C, and 700°C to examine pressure distribution, heat transfer, particle temperature, and the formation of pyrolysis products, namely bio-oil, biogas, and biochar. The modeling was performed using COMSOL Multiphysics 6.2 with a numerical approach to represent thermal phenomena and biomass decomposition reactions during the pyrolysis process. The simulation results indicate that increasing temperature significantly affects the rate of heat transfer and the temperature distribution of coffee husk particles. At 600°C, heat transfer and temperature distribution are more uniform compared to 500°C, although heating at the particle core is not yet fully optimal. The pressure distribution shows a stable flow of pyrolysis gas from the bottom to the top of the reactor. In terms of products, increasing temperature leads to a reduction in biochar and bio-oil formation due to the occurrence of secondary reactions, while biogas production increases. The highest gas production is achieved at 700°C, indicating the most optimal condition for maximizing gas yield from fast pyrolysis. Therefore, single-particle-based CFD simulation can be used as an effective tool to understand pyrolysis mechanisms and optimize process parameters in a screw reactor.

This study investigates biomass-derived surface engineering of AISI 1020 steel for electromedical applications using galam wood charcoal and chicken bone waste as carburizing media. Surface modification is required to improve the mechanical performance of low-carbon steel, particularly in applications that demand high wear resistance and long-term durability. A pack carburizing approach was applied using various ratios of biomass-derived media at a treatment temperature of 800 °C for 2 hours. Chemical composition was analyzed using Optical Emission Spectroscopy (OES), surface hardness was evaluated using Micro Vickers hardness testing, and microstructural characteristics were observed using optical microscopy. The results show a significant increase in surface carbon content with increasing fractions of chicken bone powder, indicating its effectiveness as a carbon donor and diffusion promoter. The surface hardness increased from approximately 150 HV in the untreated condition to a maximum of about 860 HV in the treated specimen. Microstructural observations revealed the formation of a distinct carburized layer with increasing thickness and uniformity, consistent with enhanced carbon diffusion and surface strengthening. These findings demonstrate that biomass-derived surface engineering provides an effective and sustainable approach for improving the surface properties of low-carbon steel. The proposed method offers strong potential for environmentally friendly manufacturing of durable and reliable electromedical components.

Japanese kale (Brassica oleracea) is a leafy vegetable with high nutritional and economic value and strong potential for development through intensive cultivation systems, including polybag-based cultivation. Fertilization is an important factor determining plant growth success. This study aimed to analyze differences in the effects of cattle-manure compost fertilizer and NPK Mutiara fertilizer on the vegetative growth of Japanese kale, as well as to evaluate their roles in maintaining growing media fertility. The research employed a quantitative experimental approach using a single-factor Completely Randomized Design (CRD), namely fertilizer type. Treatments consisted of cattle-manure compost fertilizer and NPK Mutiara fertilizer, each with twelve replications, resulting in twenty-four experimental units. Observed parameters included plant height, leaf width, and growing media pH. The results showed that NPK Mutiara fertilizer produced better plant height and leaf width than compost fertilizer, particularly during the vegetative phase. This advantage was associated with the rapid availability of macronutrients such as nitrogen, phosphorus, and potassium for plant uptake. Meanwhile, cattle-manure compost fertilizer contributed to stabilizing growing media pH and improving soil physical and biological conditions. pH values in both treatments remained within the optimal range and did not limit plant growth. Therefore, NPK Mutiara fertilizer is more effective for short-term vegetative growth enhancement, whereas compost fertilizer supports sustainable growing media fertility.

This is related to the rights of traffic accident victims regulated in Article 240 of Law 22 of 2009 concerning Road Traffic and Transportation "traffic accident victims have the right to receive compensation from the party responsible and are entitled to insurance compensation from the insurance company". Article 1365 of the Civil Code, every person who commits an unlawful act is obliged to compensate for the losses arising from his or her mistake. In fact, many accidents occur due to damaged roads in Samarinda City, so this is one of the factors causing traffic accidents.The aim of this research is to answer two things. First, to find out and examine unlawful acts by the authorities in cases of traffic accidents due to damaged roads. Second, we want to know and examine the legal responsibilities of road operators. In this part of the research, we review and explore the relevant laws that regulate and are relevant to claims for compensation against road operators by victims of traffic accidents due to damaged roads.The results obtained from this research are as follows: 1) In this case, the occurrence of traffic accidents in terms of the last 5 years continues to show a significant increase, which means that the government has not maximally provided the community's rights, namely to have good roads. One of the causes of accidents is damaged roads, but to date no member of the public has filed a civil lawsuit against the government for compensation for the pain they suffered. 2) The government's regulations and efforts to provide protection for road users are sufficient, but they are not implemented optimally, in fact the public has never been given an appeal to demand their rights to receive good roads.
