The lifestyle of Indonesian society, especially among Generation Z, has been influenced by globalization and foreign popular culture, specifically the Korean wave or hallyu. Awareness of halal certification and knowledge and literacy about halal food are important to study as they influence Generation Z's purchasing decisions regarding Korean food. This study uses a descriptive method, namely a qualitative approach, while the type of research used is literature research in the form of books, interpretations of the Qur'an, Hadith, and others related to the problem to be solved. Halal food is food and drink that is permissible for consumption according to Islam, i.e., free from haram ingredients such as pork, meat from animals that have not been slaughtered in accordance with Islamic law, and alcohol. To determine whether food is haram, there needs to be a guarantee, such as a halal certificate, which is an absolute step to ensure that a product complies with applicable standards. Korean food is cuisine that has grown and developed from the Korean environment and culture, which has a unique taste, starting from the names of the dishes, which are able to attract the interest of the public, especially Generation Z.  

Hypertension is a non-communicable disease that can be life-threatening, especially in the elderly. According to the WHO, more than 15 million people aged 30–69 years die each year from non-communicable diseases. This study aims to analyze factors influencing the incidence of hypertension in the elderly, including smoking, stress levels, culture, diet, exercise, and coffee drinking habits. This research method used a quantitative approach with a cross-sectional design. The population was 738 elderly people, with a sample size of 259 elderly people, and random sampling was used. Data analysis was performed using univariate, bivariate using the Chi-Square test, and multivariate using the Pearson correlation test. The results of this study such as Smoking with hypertension: There is a significant influence (p = 0.002), stress level There is a significant influence (p = 0.002), Culture There is a significant influence (p = 0.010), Eating patterns with hypertension are significant (p = 0.049), Exercise There is a significant influence (p = 0.003), drinking coffee with a significant influence (p = 0.048). Multivariate analysis shows that culture (p = 0.003; r = 0.177) and coffee drinking habits (p = 0.022; r = 0.139) are the most influential factors on elderly hypertension, while other factors are not significant. This study shows that smoking, stress levels, culture, diet, exercise, and coffee consumption are significantly associated with hypertension in the elderly. However, a multivariate analysis revealed that cultural factors and coffee drinking habits were the most dominant factors influencing hypertension, while other factors had no significant effect after being controlled for. Therefore, efforts to prevent and control hypertension in the elderly need to focus on changing cultural practices that are less conducive to health and regulating coffee consumption, while still considering the implementation of a healthy lifestyle overall.

Air pollution and oil reserves are two major issues in the technological development of the automotive industry. Air pollution is caused by gases from burning fossil fuel vehicles. In 2018-2019 Indonesia experienced a drastic decrease in petroleum resources by 49.8%. To overcome this problem, many researchers have conducted research on electric vehicles, including electric bicycles. This study aims to determine the effect of distance and load on BLDC motor power consumption on a prototype e-bomber electric bicycle designed for all terrains such as rocky, sandy, and muddy, and has a large battery capacity, low power consumption, and an electric motor with good speed and torque. This research uses a pseudo-experimental method with a quantitative approach. Tests were carried out on e-bomber electric bicycles with distances of 3 km, 5 km, and 8 km and loads of 60 kg, 70 kg, and 80 kg with a speed of 25 km / h. The results showed that there was an influence of distance and load on the e-bomber electric bicycle. The results showed that there was an effect of distance and load on BLDC motor power consumption with the results of graph analysis and two-way ANOVA tests conducted and the lowest average power consumption of 500 watts at a distance of 3 km and a load of 60 kg, while the highest average power consumption was 522.5 watts at a distance of 8 km and a load of 80 kg.

Energy audits are an essential step in supporting the efficiency of electricity utilization, particularly in large-scale commercial buildings such as shopping malls. This study was conducted to measure and analyze electricity consumption at Pollux Malls Paragon Semarang using a direct measurement approach combined with historical monitoring of energy consumption. The main focus of the audit was on the lighting system and the Heating, Ventilation, and Air Conditioning (HVAC) system from the Basement to the 6th Floor. Measurement results showed that the Energy Consumption Intensity (ECI) ranged between 39.94–45.20 kWh/m²/month, far above the national efficiency standard (maximum 18.5 kWh/m²/month), indicating a highly wasteful energy usage condition. The two main systems contributing to the largest share of consumption were HVAC and lighting, with a combined estimated share exceeding 60% of the total monthly energy use. Based on the analysis, several energy-saving opportunities were identified, including the replacement of energy-efficient lighting (LED), installation of automatic control systems (light, temperature, and timer sensors), and regular maintenance of HVAC systems. With the implementation of technical, managerial, and operational efficiency strategies, it is estimated that energy consumption savings could reach 20–30%, or around 60,000 kWh per month, without compromising visitor comfort.

The use of fossil-fueled vehicles has long been a major cause of exhaust emissions that pollute the air and exacerbate global climate change. In an effort to address this problem, Indonesia has begun developing electric vehicles as a more environmentally friendly alternative solution. Electric vehicles (EVs) are considered capable of reducing dependence on fossil fuels while simultaneously reducing air pollution levels. The Indonesian government has demonstrated its commitment to supporting electric vehicle development by issuing several strategic policies, including Presidential Regulation (Perpres) Number 55 of 2019 concerning the Acceleration of the Battery-Based Electric Motor Vehicle Program for Road Transportation, and Presidential Instruction (Inpres) Number 7 of 2022 concerning the Use of Battery-Based Electric Motor Vehicles as official vehicles for central and regional government agencies. In line with these policies, research was conducted to assess the power consumption efficiency of the Ken Dedes electric vehicle prototype, designed using a 250-watt DC motor and a mid-drive system. The main focus of this research was to analyze the effect of variations in module input voltage and gear size on the vehicle's power consumption level. The method used was an experimental approach with a quantitative approach, where a series of tests were conducted on several gear combinations and input voltage levels. The results of the study indicate that variations in these two parameters—gear size and input voltage—significantly affect motor power consumption. The most optimal combination in this study achieved a power consumption efficiency of 6 Wh/km. This figure demonstrates the most energy-efficient performance in vehicle operation and can serve as a benchmark for further development of similar electric vehicles. This research provides an important contribution to efforts to encourage the use of more efficient and sustainable electric vehicles in Indonesia.

High-rise buildings such as the World Trade Center Jakarta generally have high inductive electrical loads, so that their reactive power consumption is large and the power factor decreases below the SPLN standard (≤0.85), resulting in increased power losses and operational costs. This study aims to measure the power factor value before and after repairing the detuned reactor and capacitor on the capacitor bank panel, compare the results of field measurements with ETAP simulations, and assess the feasibility of the installed capacitor bank and determine the difference in the results of the ETAP simulation between measurements and load calculations on the World Trade Center building. The methods used include literature review, field observations on the LVMDP panel, MCC and capacitor bank, discussions with supervisors, data collection of current, voltage, kW, kVAR, kVA and cos φ using Lovato DCRG8 and ampere clamp, and load simulation using ETAP software. The results show that the cosφ value increased from 0.70 to 0.95 (an increase of 35.71%), the compensated reactive power reached 204 kVAR (Lovato), 282.6 kVAR (tang ampere), and 415 kVAR (ETAP simulation), with a power factor or cosφ = 0.95. In conclusion, the replacement of detuned reactors and capacitors effectively improves the power factor in the WTC Jakarta Building, reduces reactive loads, and the ETAP simulation results are consistent with field measurements, so that the capacitor bank installed in the WTC building is declared effective in reducing reactive currents, thereby reducing kVAR, kVA loads and improving the efficiency of the electrical system distribution for better energy management

The development of wearable technology, especially smartwatches, opens up great opportunities in preventive health monitoring, especially in rural areas such as Sembung Village, Wringinanom, Gresik, where access to health services is limited. However, this technology is still alien to the local community. Preliminary surveys show that the majority of citizens, including health cadres, have never used or even seen a smartwatch in person, and view it as a luxury and irrelevant item. In fact, the potential of smartwatches as “digital health assistants” is huge from tracking heart rate, blood oxygen levels (SpO₂), stress levels, to physical activity reminders that are essential for early detection of health disorders. This service activity aims to improve digital literacy and adoption of smartwatch technology through a participatory educational approach and direct assistance. Implementation methods include: (1) coordination with the village government and health workers, (2) Interactive socialization using local languages, (3) step-by-step practical training, (4) simulation of application in the field, and (5) pre-test and post-test evaluation of 27 participants (25 health cadres, 1 midwife, 1 nurse). The results showed significant improvements: function understanding from the original value of 1.8 increased to 4.2, consumption interest from the original value of 2.1 increased to 4.0, benefit perception from the original value of 1.9 increased to 4.3, self confidence from the original value of 1.5 increased to 3.8, and digital literacy awareness from the original value of 2.0 increased to 4.1. The hands-on approach proved effective in changing participants ' mindset from skeptical to enthusiastic, proving that the digital divide is not due to incompetence, but the lack of access to contextual education. The implication is that smartwatch has the potential to become a strategic tool for village health cadres in early detection and real-time data-based health education, provided that it is supported by sustainable mentoring.

This study examines how interactive storybooks can help children aged 7 to 9 years learn about the dangers of excessive sugar consumption in packaged drinks. The book is designed with interactive techniques such as pop-up, pull-the-tab, and lift-the-flap to enhance the effectiveness of learning for children. Each mechanical method is aimed at capturing the children’s attention and delivering an educational message in an engaging and easy-to-understand way. The results show that the pull-the-tab technique was the most commonly used because of its ease of use and effectiveness in illustrating gradual changes. This technique allows children to visually see how excessive sugar consumption affects the body through changes that occur when they pull the tab on the book. Additionally, the use of pop-up and lift-the-flap methods provides a visually and physically engaging experience, which makes children more involved in the learning process. Based on the findings, interactive storybooks have proven to be a highly effective learning tool for educating children about important health issues. Therefore, book developers are encouraged to continue innovating by incorporating various interactive methods, such as adapting the books into digital formats. By doing so, a broader and more effective educational impact can be achieved, allowing children to learn in a fun, interactive, and easily accessible way.

The development of digital technology and the massive penetration of social media have transformed consumption patterns, particularly among younger generations. Excessive use of social media may lead to addictive behavior, which has the potential to trigger psychological anxiety such as fear of missing out, and ultimately encourage impulse buying behavior. Denpasar City, as a center of urbanization and consumption in Bali, serves as an appropriate location to examine this phenomenon, as its community tends to be consumptive and highly active in social media use. The purpose of this study is to explain the role of fear of missing out in mediating the effect of social media addiction on impulse buying. This study employs Uses and Gratifications (U&G) theory as the theoretical foundation, with a sample of 130 respondents selected using purposive sampling. Data collection was conducted through a questionnaire method. The study applied descriptive and inferential techniques, including Path Analysis, Classical Assumption Test, and Sobel Test. The findings reveal that fear of missing out mediates the effect of social media addiction on impulse buying. This study strengthens the understanding that social media not only influences social interaction but also shapes impulsive consumption behavior as a result of psychological pressure and exposure to digital content.

Boyolali is known as a milk-producing city, which makes animal husbandry one of the biggest options for economic activity. Limited forage resources are one of the problems faced by breeders. This activity aims to provide fermentation training using dry leaves as an alternative animal feed. The method used is to collect dry leaves from local resources in Sumbung Village, followed by training on the fermentation process using probiotic bacteria, which has been proven to be effective in increasing the nutritional value of feed. Fermented dry leaves have an aroma and taste that livestock like, thereby increasing feed consumption. Utilizing fermented dried leaves as animal feed can be a sustainable solution for overcoming limited food sources in Sumbung Village. Apart from providing a higher-quality alternative feed, this research can also support efforts to manage dry leaf waste and encourage environmental sustainability.  

Iron deficiency anemia is a significant public health problem in pregnant women, because it can cause maternal and fetal complications. Compliance with iron tablet consumption is often low due to limited knowledge, side effects, and cultural misconceptions. Leaflet-based education is a low-cost intervention that has the potential to improve understanding and compliance. This study aims to analyze the effect of leaflet education on the adherence of iron tablet consumption in pregnant women at the Pujon Health Center, Batu. The research design used a quasi-experiment with a pretest-posttest control group design. A total of 40 pregnant women were divided into an intervention group (n = 20) that received leaflet education and a control group (n = 20) that received standard counseling. Compliance was measured over four weeks through self-consumption records and tablet count calculations, while knowledge was assessed with a structured questionnaire. Data analysis used the Chi-square test with a significance level of p < 0.05. Results showed a significant improvement in adherence in the intervention group, with 70% of pregnant women complying compared to 15% in the control group (p = 0.001). Leaflet education also increased knowledge scores and consistency of iron tablet consumption. The conclusion of this study confirms that leaflet education is effective in increasing iron supplementation adherence, so it is recommended to be integrated into routine antenatal services to prevent anemia and support maternal and fetal health.

However, environmental degradation caused by human greed, uncontrolled exploitation of natural resources, and unsustainable consumption patterns has led to widespread ecological crises across various parts of the world. This study aims to examine in depth how ecological values embedded in Buddhist teachings can foster strong environmental awareness, particularly among Buddhist communities. Using a qualitative literature review method, the study systematically analyzes various textual sources, including Buddhist scriptures, classical literature, and contemporary ecological literature. The findings indicate that Buddhist teachings, which emphasize the principles of interdependence, moral ethics, mindfulness, and respect for all living beings, can cultivate attitudes of care and responsibility toward the environment when these values are consistently integrated into education from an early age, both within families, schools, monasteries, and the broader community. This study makes a significant contribution to the discourse on religion-based ecological ethics by positioning Buddhist ecology as a conceptual framework for the sustainable and profound transformation of ecological consciousness.

The increasing demand for cloud computing services has led to the rapid expansion of cloud data centers, which consume significant amounts of energy and contribute substantially to global CO2 emissions. As the IT industry grows, the environmental impact of these data centers becomes an urgent concern. Green Cloud Computing (GCC) has emerged as a solution to mitigate this impact by focusing on energy efficiency and reducing carbon footprints while maintaining the necessary functionality and performance of cloud infrastructures. However, traditional blockchain consensus algorithms such as Proof of Work (PoW) and Proof of Stake (PoS) face limitations regarding energy consumption and scalability, which exacerbates the environmental burden. This study proposes a quantum-inspired blockchain consensus algorithm designed to optimize energy consumption and reduce latency in cloud data centers. By integrating quantum principles such as superposition and entanglement, the algorithm enhances task scheduling and resource utilization, enabling more energy-efficient operations without sacrificing performance. Simulations in a green cloud environment showed that the quantum-inspired algorithm resulted in up to a 30% reduction in energy usage compared to traditional consensus methods, with a 40% improvement in consensus processing time. These results suggest that quantum-inspired algorithms hold significant potential for enhancing the sustainability of cloud infrastructures by improving energy efficiency and scalability. Furthermore, this study discusses the feasibility of implementing quantum-inspired algorithms on classical hardware, addressing challenges in scalability and integration into existing blockchain frameworks. The findings provide valuable insights into the potential of quantum-inspired technologies to drive energy-efficient solutions in cloud computing.
