The rapid growth of Solar Power Plant (PLTS) installations in Indonesia faces efficiency challenges due to the continuously changing position of the sun. Fixed panel systems cannot absorb solar radiation optimally throughout the day. This study aims to evaluate and compare the efficiency of various solar tracking system methods developed over the last five years using a simple literature review approach. The research method was conducted by collecting, screening, and synthesizing secondary data from five reputable scientific journals using a synthesis matrix. The review results indicate that single-axis tracking systems increase power efficiency by 15% to 24.5%. Meanwhile, dual-axis systems achieve higher efficiency, ranging from 30% to 35%, by tracking both horizontal and vertical solar movements. In terms of control systems, astronomical algorithms are found to be more reliable in cloudy weather conditions than pure light sensors. However, the internal power consumption of the actuator motors remains a critical factor that can reduce the system's net energy gain. The implication of this study emphasizes the importance of shifting future research focus toward energy-saving algorithm optimization to maximize net power yield in dynamic solar panel implementations.

The rapid development of financial technology, particularly online lending, has transformed consumption patterns among working-age individuals by providing easy access to digital credit. This study aims to analyze the influence of financial literacy and online loans on the consumptive lifestyles of gas station workers in the Bululawang area. An explanatory quantitative approach was employed, with all gas station workers serving as the study population. A saturated sampling (census) technique was applied, and data were collected through digital Likert-scale questionnaires. The hypotheses were tested using Multiple Linear Regression Analysis. The findings indicate that financial literacy does not significantly reduce consumptive lifestyles, suggesting that financial knowledge alone is insufficient to control spending behavior without strong self-discipline. In contrast, the use of online loan applications has a significant positive effect on consumptive behavior, as rapid access to credit creates a perception of greater purchasing power and encourages impulsive spending to satisfy lifestyle and social prestige. Simultaneously, limited financial literacy combined with easy access to digital credit significantly increases consumptive lifestyles. The study concludes that improving financial management requires not only theoretical financial literacy but also practical financial discipline. Therefore, companies are encouraged to provide continuous financial education and develop safer internal financing alternatives to reduce workers' dependence on digital lending platforms.

The rapid development of digital technology has transformed the dissemination and consumption of religious information among Muslim communities. Alongside these advancements, the spread of Inkār al-Sunnah ideology through digital platforms has become a significant challenge to the integrity of Islamic religious understanding, particularly among younger generations who are frequently exposed to unverified religious content. This phenomenon has the potential to weaken the authority of the Sunnah as a primary source of Islamic teachings alongside the Qur'an. This study aims to examine Islamic education strategies in countering the spread of Inkār al-Sunnah in the digital era, focusing on strengthening hadith literacy, enhancing the role of Islamic Education teachers, utilizing digital media, and developing religious moderation education. The research employs a qualitative approach through library research and content analysis of relevant academic literature. The findings indicate that the challenge of Inkār al-Sunnah affects three dimensions of Islamic education: curricular, pedagogical, and socio-digital. In response, a multidimensional strategy is required, including strengthening Islamic epistemology, improving hadith literacy, contextualising learning through the living hadith approach, reformulating hadith curricula, optimizing educational digital media, enhancing teacher competencies, strengthening Islamic educational institutions, fostering family-school collaboration, and promoting religious moderation education. The study concludes that adaptive and integrative Islamic education, grounded in the Qur'an and Sunnah, plays a crucial role in developing a generation of Muslims who are critical, knowledgeable, digitally literate, and moderate in responding to contemporary religious challenges in the digital age.

Plastic waste, particularly bottle caps, poses a significant environmental challenge due to its slow degradation rate. This study aims to design a functional shoe rack utilizing plastic bottle cap waste to support Sustainable Development Goals (SDG 12: Responsible Consumption and Production). The product development process employed the Quality Function Deployment (QFD) method to translate consumer needs into measurable technical specifications. Concept selection was evaluated using the Pugh Matrix, while financial feasibility was analyzed through the Break Even Point (BEP) approach. The research resulted in an optimal shoe rack design measuring 53x32x37 cm, weighing 1.5 kg, and featuring additional side hangers for socks. The production process involves shredding, molding with resin, cutting, and assembling, with a total duration of 367.03 minutes. Financial analysis indicates that the business reaches the break-even point at a minimum production of 2 units or a total sales value of Rp227,272. This research demonstrates that integrating industrial engineering methods into plastic waste management can produce functional, durable, and economically viable products.

The development of electric vehicle technology has encouraged the use of electric bicycles as an environmentally friendly and energy-efficient mode of transportation. One of the main components of an electric bicycle is the hub BLDC (Brushless Direct Current) motor, which is considered more efficient because it is directly integrated into the wheel without requiring a chain transmission system. However, the performance of the hub BLDC motor is affected by operating conditions, particularly variations in load and speed, which influence current consumption and overall electrical performance. This study aimed to analyze the effect of load and speed variations on the current consumption of a hub BLDC motor. A quantitative experimental method was employed by conducting direct tests on an electric bicycle using load variations of 50 kg, 60 kg, and 70 kg, as well as speed variations of 30 km/h, 35 km/h, and 40 km/h. Current measurements were carried out in real time using a PZEM 051 sensor, and the collected data were analyzed using average values obtained from repeated measurements. The results showed that increasing the load and speed led to higher current consumption of the hub BLDC motor, from 4.6 A to 5.0 A under load variation and from 4.5 A to 5.1 A under speed variation. These findings indicate that both load and speed significantly affect the electrical current required by the hub BLDC motor, demonstrating that greater operating demands result in higher energy consumption.

Background: Adolescence is often characterized as a period of puberty. Early menarche is associated with increased mortality and morbidity risks in later life among girls who experience menarche at an early age. Menarche is the first menstrual event in girls, marked by the shedding of the uterine lining and vaginal bleeding. The tendency to consume unhealthy foods, particularly fast food, as well as sugar-sweetened beverages (SSBs), may have adverse effects on health and potentially influence the timing of menarche. Objective: This study aimed to analyze the relationship between healthy food selection, sugar-sweetened beverage consumption, and the incidence of early menarche. Methods: This study employed a cross-sectional design. The sample consisted of 30 female students. Data were analyzed using the Spearman Rank correlation test. Results: The results showed that healthy food selection was significantly associated with the incidence of early menarche (p = 0.005) with a moderate correlation strength (ρ = 0.449). Similarly, sugar-sweetened beverage consumption was significantly associated with the incidence of menarche (p = 0.000) and demonstrated a very strong correlation (ρ = 0.841). Conclusion: There was a significant relationship between healthy food selection and sugar-sweetened beverage consumption with the incidence of menarche. Sugar-sweetened beverage consumption showed a stronger relationship with menarche incidence compared to healthy food selection.

Traditional wedding rituals constitute intangible cultural heritage rich in symbolic meaning, serving to strengthen social solidarity and transmit cultural values. The massive penetration of modernization and digitalization has created new pressures for the Bugis-Makassar community in maintaining this heritage. This study analyzes the transformation of Bugis-Makassar traditional wedding rituals in South Sulawesi within the digital era context, focusing on how the community negotiates their cultural identity between the forces of tradition and modernity. Using a critical ethnographic approach with a multiple case study design grounded in Bhabha's concept of the third space, the study involved 42 informants from three groups: young couples (digital generation, aged 22–35), parents/family (middle generation, 40–60), and customary elders (to panrita lopi/bissu, 65+) in Makassar City, Bone Regency, and Wajo Regency. Data were collected through in-depth interviews, participant observation in 12 wedding ceremonies, and social media content analysis. Results reveal three main transformation patterns: (1) digital spectacularization—rituals adapted for social media consumption; (2) reflective selectivity—young couples actively choosing which traditional elements to retain; and (3) procedural hybridization—the integration of customary procedures with contemporary elements. These transformations are colored by intergenerational contestation that generally ends in compromise between demands for customary completeness and the aesthetic preferences of the younger generation. The study concludes that this transformation is not merely a loss of tradition, but a creative form of identity negotiation in which the Bugis-Makassar community actively reconstructs the meaning of siri' (self-esteem/dignity) and pesse (solidarity) within the changed socio-cultural landscape. The findings imply the need for cultural preservation policies that understand change as inherent to living culture, and open avenues for longitudinal studies on the intergenerational transmission of cultural values.

Background: The rising global burden of hypertension presents a massive public health challenge, with its mitigation heavily tied to modifiable dietary factors. Among these, the escalating intake of sugar-sweetened beverages (SSBs) has emerged as a significant dietary risk. Objectives: This study aims to synthesize recent epidemiological evidence regarding the association between various types of sweetened beverages and the risk of hypertension. Methods: A narrative-analytical review was conducted by retrieving observational studies and meta-analyses published between 2023 and 2026 from the Scopus database using explicit keyword combinations targeting SSBs, prospective cohorts, and blood pressure outcomes. Findings: Synthesized data reveals that high consumption of traditional SSBs significantly increases hypertension risk by 13% (RR: 1.13) and elevates systolic blood pressure in children, primarily driven by excess liquid calories. Artificially sweetened beverages (ASBs) show a 14% risk increase in observational data, potentially confounded by reverse causation, whereas acute pure fructose ingestion triggers rapid transient blood pressure elevation. Energy drinks induce rapid 24-hour blood pressure spikes due to high caffeine content. Conversely, 100% pure fruit juice exerts a protective effect (RR: 0.74) via endothelial-improving polyphenols, while honey demonstrates a neutral effect. Implications: Public health policies must implement aggressive regulatory interventions, such as taxation on SSBs and energy drinks, alongside targeted dietary counseling that differentiates between harmful liquid sugars and protective natural fruit juices.

The continuous increase in paper consumption has a direct impact on waste accumulation and environmental degradation due to the exploitation of wood as the primary raw material. This study aims to design an innovative product called seed paper as a solution for managing paper and cardboard waste, transforming it into something more useful while supporting Sustainable Development Goal (SDG) No. 12 on responsible consumption and production. The production method involves several stages: processing waste into pulp, mixing it with chili seeds, followed by natural printing and drying. The analysis shows that both paper and cardboard waste can be processed into an effective planting medium, where the paper naturally decomposes and the embedded seeds germinate once planted. In terms of production costs, one batch of seed paper requires approximately Rp23.000 for the paper variant and cardboard variant. Technically, this process demonstrates that waste, which would otherwise accumulate in landfills, can be transformed into an innovative product that promotes reforestation while also carrying economic value through a structured calculation of the cost of goods sold.

The increasing demand for electricity and high dependence on the utility power grid have driven the adoption of photovoltaic (PV) power generation as an environmentally friendly alternative energy source. This study aims to analyze the techno-economic feasibility of a load-sharing PV power generation system, focusing on technical analysis, operational costs, electricity bill savings, and environmental impacts. The research was conducted using quantitative methods to compare energy from photovoltaic generation and the grid, carbon emission calculations using an emission factor of 0,87 kgCO₂/kWh, and economic evaluation through parameters such as Net Present Value (NPV), Return on Investment (ROI), Cost of Energy (COE), and Payback Period (PP). The research results indicate that the photovoltaic panel generation system enables reducing utility grid energy consumption and reducing carbon emissions by 4,85 tons of CO₂ in 2024, increasing to 8,45 tons of CO₂ in 2025. The economic analysis indicates that the NPV value is not yet optimal; however, the ROI stands at 15%, the COE is Rp. 980.08/kWh, and the Payback Period is 6,56 years. The system is feasible for long-term investment. Overall, the implementation of the photovoltaic power plant demonstrates good potential in supporting carbon emission reduction, increasing the utilization of renewable energy, and reducing dependence on fossil-based energy.

The rapid expansion of digital finance services, particularly Buy Now Pay Later (BNPL) platforms such as Shopee PayLater, has significantly altered consumption patterns among university students. The aim of this study is to examine the effect of Shopee PayLater usage and lifestyle on consumptive behavior, as to test the moderating role of financial literacy among Accounting Education students at Universitas Negeri Semarang (class of 2022). A quantitative explanatory approach was employed, with data collected via Likert-scale questionnaires distributed to 63 respondents selected through purposive sampling. Data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) with SmartPLS 4. Results show that Shopee PayLater usage positively and significantly affects consumptive behavior (path coefficient = 0.440, p = 0.000), as does lifestyle (path coefficient = 0.408, p = 0.003). Financial literacy, however, does not directly influence consumptive behavior (p = 0.676). Notably, financial literacy significantly strengthens—rather than weakens—the effect of lifestyle on consumptive behavior (interaction coefficient = 0.253, p = 0.019), while it does not moderate the relationship between Shopee PayLater usage and consumptive behavior (p = 0.712). These findings contribute theoretically by extending the Theory of Planned Behavior, demonstrating that BNPL accessibility and lifestyle orientation are stronger predictors of consumptive behavior than financial knowledge alone. Practically, this study suggests that financial literacy interventions must be accompanied by self-regulation strengthening and consumer protection policies to effectively curb excessive consumption driven by digital credit services.

Diesel engines are widely used in the transportation and industrial sectors due to their high thermal efficiency and good operational durability. However, increased fuel consumption due to inefficiency of the injection system remains a common problem. Injector characteristics, particularly nozzle diameter and injection pressure, are important factors that affect the quality of fuel atomization, air-fuel mixing, and combustion efficiency. An inappropriate combination of parameters can cause suboptimal combustion and increase fuel consumption. This study aims to analyze the effect of variations in nozzle diameter and injection pressure on fuel consumption efficiency in diesel engines. The method used is an experiment with variations in nozzle diameter of 0.150 mm, 0.152 mm, and 0.154 mm and injection pressures of 400 bar, 420 bar, and 440 bar. Tests were conducted at engine speeds of 500 rpm, 1000 rpm, and 1500 rpm with a fuel consumption measurement time of one minute for each parameter combination. Fuel consumption was measured using the volumetric method and analyzed through the fuel volumetric flow rate, fuel mass flow rate, Brake Power (BP), and Brake Specific Fuel Consumption (BSFC). The results showed that the combination of a nozzle diameter of 0.150 mm and an injection pressure of 400 bar produced the lowest BSFC value, thus providing the best fuel consumption efficiency. Meanwhile, the combination of a nozzle diameter of 0.152 mm and an injection pressure of 420 bar showed the closest condition to optimal because it was able to provide a balance between atomization quality and the amount of fuel injected, resulting in efficient and stable combustion. Thus, the efficiency of a diesel engine is influenced by the balance of nozzle size and injection pressure, not solely by the lowest fuel consumption.

High consumption of sugar-sweetened beverages (SSBs) has become an increasing public health concern, particularly among adolescents. Excessive SSB intake is a major risk factor for various non-communicable diseases, including type 2 diabetes mellitus, cardiovascular diseases, obesity, dental caries, and certain types of cancer. This study aimed to analyze the factors associated with the level of sugar-sweetened beverage (SSB) consumption among adolescents. This study employed a descriptive literature review approach. Data were obtained from national and international journals relevant to the topic of SSB consumption among adolescents. The selected articles were analyzed to identify factors associated with SSB consumption. The findings indicated that SSB consumption among adolescents is influenced by several factors, including individual factors (gender and knowledge), socioeconomic factors (peer influence and pocket money allowance), environmental factors (mass media exposure and beverage availability), and psychological factors (stress level and preference for sweet tastes). This study highlights that SSB consumption is a multifactorial behavior influenced by various interacting determinants. Therefore, comprehensive interventions targeting both individual and environmental factors are needed to reduce SSB consumption among adolescents.

The study aims to analyze the influence of consumption behavior, projected through cultural, social, personal, and psychological factors, through Generation Z's decision to use the Quick Response Code Indonesian Standard (QRIS). The focus subjects were taken from undergraduate students of Economics at Surabaya State University from 2021 to 2024 who are active users of QRIS. Using an associative quantitative approach using primary data to be collected using an online questionnaire distribution. The data analysis technique applied Structural Equation Modeling–Partial Least Square (SEM-PLS) using SmartPLS 4 software. The results of the study showed that four factors of consumption behavior, namely cultural factors, social factors, personal factors, and psychological factors, have a positive and significant impact on students' decisions to use QRIS. Evaluation of the F-square value F2 shows that psychological factors (internal motivation, perceived ease, security, and trust) are the most dominant predictors with the largest effect value of 0.434 in influencing the decision to adopt this digital payment system technology. These findings indicate that a combination of students' internal motivation, the digital culture inherent in the campus environment, and the demands of practicality in Generation Z's lifestyle strengthen the decision to use QRIS in daily economic activities.

The millennial generation holds a strategic role in the economy but is prone to consumptive behavior due to low financial literacy. This study aims to analyze the influence of financial literacy on the consumption behavior of the millennial generation in Banda Aceh City, and to test the role of demographic factors (education, occupation, and income) as a moderating variable. A quantitative approach was employed using a survey method on 100 respondents aged 28–43, selected through random sampling. Data were analyzed using simple linear regression and Moderated Regression Analysis (MRA). The results indicate that financial literacy has a significant and positive influence on consumption behavior. Another finding is that demographic factors were unable to significantly moderate this relationship. However, simultaneously, all variables in the model significantly influence Consumption Behavior, contributing 92.8% of the variation. These findings underscore the importance of increasing financial literacy as a dominant strategy for promoting more rational consumption behavior among the millennial generation.

The quality of rice that is suitable for consumption, one of which is determined by the absence of associated components when the rice is in storage. Rice storage is carried out by means of long shelf life and good rice quality. Damage to rice due to pest attacks causes a decrease in quality and quantity. Environmentally friendly efforts are needed to control the rice weevil Sitophilus oryzae using vegetable materials. This study sought to ascertain the death rate of rice weevils treated with lemongrass stem (Cymbopogon citratus), bay leaves (Syzygium polyanthum), and pandan leaves (Pandanus amaryllifolius). The study employed a fully randomized design with three treatments in the form of simplicia plant components. There were 21 study units because each treatment included seven repetitions. Each treatment used 20 rice weevil imago breeding results which were infested in a jar containing 200 g of rice for 4 weeks in the laboratory. The use of pandan leaf, bay leaf, and lemongrass simplicia at 7 days after treatment showed the proportion of rice weevil mortality was 59,29%, 39,29%, and 50,00%, respectively. As for the observations of 14 day after treatments, 21 day after treatments, and 28 day after treatments showed that the mortality rate of all rice beetles was above 50%. Regarding the percentage of rice powder, hollow rice, and rice weight loss, the findings of observations on rice weevil mortality did not reveal any significant variations across all treatments.

Antimicrobial resistance is a persistent threat to hospital care, particularly when empirical therapy relies on broad-spectrum antibiotics without continuous evaluation of local use and susceptibility patterns. This literature review aimed to synthesize evidence from four Indonesian hospital-based studies regarding antibiotic utilization, rationality assessment, and bacterial resistance profiles. A structured narrative review was conducted using four selected articles provided by the author. Data were extracted for study design, setting, population, antibiotic evaluation method, dominant antibiotic classes, rationality indicators, resistance profile, and stewardship implications. The four studies were descriptive and hospital-based, using retrospective records, concurrent observation, ATC/DDD with DU 90%, qualitative rationality criteria, and antibiogram data. The synthesis showed a consistent concentration of antibiotic use in broad-spectrum groups, especially third-generation cephalosporins, penicillins, quinolones, and macrolides. In a Bandung public hospital, total antibiotic consumption reached 95,719.01 DDD, with penicillins, cephalosporins, quinolones, macrolides, and sulfonamides included in the DU 90% segment. In intensive care, ceftriaxone was the most frequently used antibiotic and most rationality indicators were appropriate, although clinically significant drug interactions were still identified. In pediatric acute respiratory infection inpatients, cefotaxime and ceftriaxone dominated empirical therapy. Resistance mapping in Denpasar highlighted relevant Gram-positive and Gram-negative pathogens and recommended antibiotics according to susceptibility levels. Overall, the reviewed evidence supports an integrated antimicrobial stewardship model combining ATC/DDD-DU 90% surveillance, qualitative rationality evaluation, antibiogram-based empirical guidance, and periodic feedback to prescribers.

Increased caffeine intake is commonly used by students to cope with academic demands, especially during examinations and the completion of final projects. Excessive caffeine consumption may affected sleep quality and potentially influence nutritional status. This study aimed to determine the correlation between caffeine intake, sleep disturbances, and nutritional status among final – year unsergarduated students at Dr. Soekardjo University. This study used quantitative approach with an observational analytic and cross-sectinal design. A total of 108 students participated in the study. Data were collected using questionnaires and analyzed using the Spearman Rank correlations test. The findings indicated that the most of respondents with low caffeine intake experienced mild sleep disturbances, totaling 56 respondents (80%). Meanwhile, respondents with moderate and high caffeine intake mostly experienced moderated sleep disturbances, with 13 respondents (61.9%) and 9 respondents (52.9%), respectively. The results showed a significant correlation between caffeine intake and sleep disturbances (p-value=0.000). In all categories of caffeine intake, most respondents had normal nutritional status. However, no significant relationship was found between caffeine intake and nutritional status (p-value=0.351). In conclusion, caffeine intake was associated with sleep disturbances but not with nutritional status among final-year undergraduate students.
