This study analyzes social change in Ponggok Village, Klaten, Central Java, from an impoverished village to a self-sufficient one, utilizing Talcott Parsons' structural functionalist framework and the AGIL model (Adaptation, Goal Attainment, Integration, Latency). Prior to 2006, Ponggok Village faced poverty, inadequate infrastructure, and limited employment opportunities, despite its significant potential for spring water. The transformation began in 2009-2013 with collaboration between the village head and academics for potential mapping and the establishment of the Village-Owned Enterprise (BUMDes) Tirta Mandiri. The period from 2014 to 2018 marked a "golden era" with the implementation of the Village Law of 2014, increased village funds, and peak revenues from Umbul Ponggok. However, from 2019-2023, the village experienced a significant decline due to the COVID-19 pandemic. A descriptive qualitative research method with a case study approach was employed, dividing the timeline into three periods (2009-2013, 2014-2018, 2019-2023). Data were collected through Focus Group Discussions, interviews, and literature reviews. The research findings demonstrate how Ponggok Village systematically fulfills the AGIL functional prerequisites by examining socio-economic policies through policies implemented by the Village Government, Village Consultative Body (BPD), and Village-Owned Enterprise (BUMDes) in efforts to improve quality of life, foster social integration among stakeholders, and maintain values through sustainable programs aimed at achieving and sustaining the success of its transformation. These findings provide a holistic understanding of the village’s resilience and adaptability in facing social and economic challenges.

Low Back Pain (LBP) is one of the most common musculoskeletal problems experienced by people in various age groups and work backgrounds. This complaint can be acute, subacute, or chronic, with various causes ranging from mechanical, degenerative, to psychosocial factors. This study aims to examine the characteristics of LBP through a literature review of several previous studies that focus on prevalence, risk factors, and their impact on patients' daily lives. The method used is a narrative literature review, with data sources coming from national and international journals, research reports, and academic repositories. The results of the study show that the prevalence of LBP is very high, with a significant percentage of occurrence in the elderly, pregnant women, administrative workers, and individuals with a sedentary lifestyle and non-ergonomic work posture. In addition to age, female gender, non-ideal body mass index, and long work duration, it was also found that psychosocial characteristics such as low social support and high work pressure play a role in triggering or worsening LBP. A study at Ibnu Sina Hospital Makassar showed that most LBP patients were elderly women with acute pain and radiological results showed lumbar spondylosis as the most common diagnosis. The conclusion of this study emphasizes the importance of prevention through ergonomic education, work stress management, and early intervention based on a healthy lifestyle. These findings are expected to be the basis for designing promotive and preventive strategies for high-risk groups.

This study aims to analyze the legal protection of personal data subjects in the case of the 2024 data breach at the Temporary National Data Center (PDNS) managed by the Ministry of Communication and Informatics (Kominfo), based on Law Number 27 of 2022 on Personal Data Protection. The research employs a normative juridical method with a case study approach and statutory analysis. Legal materials are obtained from primary and secondary sources using literature research techniques. The findings reveal that Kominfo, as a public body and personal data controller, has not fully fulfilled its obligations to protect personal data as mandated by the law, as reflected in weak security systems, lack of transparency, and slow response to the breach incident. This study highlights the urgent need for the establishment of implementing regulations and an independent supervisory institution to ensure the effective protection of personal data for the public in Indonesia.

This study aims to examine how the construction of sexuality is represented and perceived through Instagram social media. As a dominant visual platform, Instagram plays an important role in shaping body image, gender, and intimate relationships that are often influenced by popular culture, media algorithms, and prevailing social norms. Using a qualitative approach and in-depth interview method with six informants, this study found that the representation of sexuality on Instagram generally reflects ideal body standards, which can cause social and psychological pressures, such as body anxiety, insecurity, and objectification. On the other hand, some users also see Instagram as a space for self-expression, empowerment, and education, especially for those who have a critical awareness of the social construction behind the content. Perceptions of ideal sexuality also vary widely, depending on the cultural background, personal experiences, and visual preferences of each user. These findings emphasize the importance of media literacy and critical reflection so that social media can become a healthier, fairer, and gender-inclusive digital space.

Imbalance of body lipid levels, especially total cholesterol and HDL, is a major risk factor for cardiovascular disorders. A simple lipid profile examination can be used to detect potential atherogenic dyslipidemia that has not shown clinical symptoms. Total cholesterol and HDL levels were examined in 104 participants using the Point-of-Care Testing (POCT) technique. Education was provided individually using leaflets, which contained information on the effects of saturated fat and trans fat consumption, and the importance of unsaturated fat and fiber intake on lipid profiles. Most participants had total cholesterol levels within normal limits. However, more than half of the population showed low to very low HDL levels, indicating hidden metabolic risks. Dietary education was provided in a targeted manner according to the results of each participant's examination. Total cholesterol and HDL examinations were used to assess the risk of lipid disorders early on. Nutrition education based on examination results is useful in raising awareness of the importance of regulating diet to reduce the risk of atherosclerosis and cardiovascular complications.

Organic church and church management are often viewed as two opposing approaches: one emphasizes spiritual vitality and relational community life, while the other focuses on structure, planning, and organizational sustainability. This study argues that these approaches need not be placed in tension; rather, they can be integrated into a coherent and holistic framework of ministry. Using a descriptive qualitative approach through literature analysis, this research explores how the concept of the organic church in New Testament ecclesiology can be integrated with key principles of modern church management. Insights from Bonhoeffer (1954) on communal life, Erickson (1998) on the nature of the body of Christ, and Tomatala (2014) on congregational development provide the foundational basis for this integrative model. The findings indicate that the organic church contributes life, relational depth, and the dynamic work of the Holy Spirit, whereas church management offers direction, coordination, and the structural space needed for spiritual gifts to function. Together, these dimensions produce a living structure that is flexible, relational, theological, and accountable. The study concludes that the contemporary church requires structures that support life rather than replace it.

Work fatigue is a physical condition that weakens workers, causing less than optimal work capacity and endurance. Lactic acid is produced from anaerobic metabolism or carbohydrate metabolism without oxygen. This happens because there is not enough oxygen to support muscle energy production. The body that cannot produce the amount of lactic acid that is comparable to the rate of its synthesis, then the muscle pH will decrease, this is what inhibits glycolysis enzymes resulting in physical fatigue. Physical fatigue is the effect of increased levels of lactic acid in the body, especially muscles. One of the jobs at PT. X in Kampar Regency that can cause work fatigue is a palm oil harvester. This study is an observational study type with a cross-sectional study design. Data were obtained using interviews using a BMI questionnaire. Data collection was also carried out to obtain BMI measurement data, pulse measurements, blood pressure measurements, and lactic acid measurements with Accutrend Plus Roche Brand on 138 harvesters at PT. X Kampar Regency. In this study, the independent variable is the level of lactic acid and the dependent variable is work fatigue. The results of the study showed that the harvesters who experienced moderate work fatigue were 13 people (11.4%). The harvesters who experienced high work fatigue were 54 people (47.4%). The harvesters who experienced very high work fatigue were 47 people (41.2%). The high proportion of workers who experienced high and very high work fatigue (88.6%) reflects the significant physical workload that must be faced by oil palm harvesters at PT. X. Harvesters with lactic acid levels <2 mmol/l (not increasing) were 13 people (11.4%) and harvesters with lactic acid levels> 2 mmol/l (increasing/hyperlactatemia) were 101 people (88.6%). From the results obtained, a significant increase in lactic acid levels in 88.6% of respondents indicated that most workers experienced higher muscle fatigue conditions during work with increased lactic acid levels.

Plastic waste is currently still a serious problem for society due to the lack of sensitivity to environmental problems and the impact of careless disposal of plastic waste in many places. The injection molding process on industry scale often faces obstacles such as machines that have not worked efficiently, injection capacity that is unable to fill the mold completely, and the emergence of product defects due to plastic flow that begins to freeze before the entire cavity is completely filled. This study aims to design and simulate a prototype injection molding machine with a capacity of 4 tensile test specimens (total volume 28.5 cm³) in order to overcome these problems and to adjust the practicum needs of mechanical engineering students. The design process is carried out with SolidWorks software for 3D design, as well as flow simulation using SolidWorks Plastics and Flow Simulation with recycled Polypropylene (PP) material at melting temperature ± 230 ° C and injection pressure ± 5.3 MPa. The design results in a machine with dimensions of 1273 × 400 × 826 mm equipped with main components in the form of a frame, electric motor and gearbox, hopper, body safety, wheels, piston cylinder, control panel, heater, screw with barrel, and mold. SolidWorks Plastics simulation shows that the plastic flow fills the mold evenly with a filling time of 10.93 seconds, cycle time of 83.94 seconds, and maximum pressure of 5.38 MPa in the gate area, while Flow Simulation simulation shows a spiral flow pattern from the hopper to the end of the mold without backflow, with a mass flow rate of 0.0227 kg/sec and an average pressure of 97.765 Pa. These results prove that the design and simulation can improve process efficiency and mold quality

This study aims to analyze the effect of body angle variations on propulsion force, drag coefficient, and freestyle swimming performance using a biomechanical approach. The background of the study is based on the importance of movement efficiency in swimming which greatly affects athlete performance. The research method used a quantitative experimental design involving university or club level swimmers who have a minimum of three years of training experience. Subjects were selected through purposive sampling with the criteria of being healthy, accustomed to using freestyle techniques, and willing to follow the research procedure. The instruments used included 3D motion capture to record body angles and movement coordination, force sensors to measure propulsion force and drag coefficient, and a time recording system to calculate average speed. The research procedure was carried out by providing variations in body angles of 0°, 15°, and 30°, each with three replications. The data obtained were analyzed using descriptive statistics to describe the average, standard deviation, and data distribution, as well as comparative statistics (ANOVA or paired t-test) to compare performance between angle variations. The results showed that a 15° body angle provided optimal performance, characterized by increased average speed and propulsive efficiency compared to 0° and 30° body angles. These findings confirm that body angle regulation is a key factor in reducing water resistance and increasing propulsive effectiveness. The discussion of the results indicates that applying biomechanical analysis to swimming training can provide objective information for developing training techniques and strategies. Therefore, this study concludes that a 15° body angle is the most ideal position for improving freestyle swimming performance. Further research is recommended to expand the number of subjects, explore variations in other swimming styles, and integrate physiological data to obtain a more comprehensive picture.

Uric acid (UA) is a waste product formed when the body breaks down purines, which are natural compounds found in the body and can be found in various types of foods such as alcohol, shellfish, and liver. Hyperuricemia is caused by increased uric acid production, decreased excretion, or a combination of both processes. Most people with hyperuricemia are asymptomatic (85% to 90%), but increased levels of uric acid in the blood or urine can cause gout or nephrolithiasis. Hyperuricemia and hyperuricosuria are also associated with other disorders such as metabolic syndrome, diabetes mellitus, cardiovascular disease, hypertension, atherosclerosis, obesity, and chronic kidney disease. The Community Service (PKM) activity held in Grogol Village, West Jakarta, aims to increase awareness of the elderly community regarding the importance of early detection of hyperuricemia. This program uses the Plan-Do-Check-Act (PDCA) approach, starting from planning uric acid level examinations and compiling educational materials, followed by implementing interactive screening and counseling, evaluating results, and following up in the form of medical referrals for participants with abnormal results. Of the 71 participants involved, only 1 person had uric acid levels above normal. Through education on low-purine diets, the importance of hydration, and physical exercise, this activity is expected to be able to reduce the incidence of hyperuricemia and its complications, as well as support the realization of a healthier elderly community that is aware of its metabolic health.

This study aims to analyze the influence of service quality, destination attraction, and supporting facilities on visitor loyalty in the context of halal tourism at Maimun Palace, Medan City. Employing a quantitative approach with an associative research design, the study involved 254 respondents selected using the Slovin formula from a total population of 689 visitors recorded in April 2025. Data were collected through a structured questionnaire using a Likert scale and analyzed using SPSS software. The findings reveal that each independent variable—service, attraction, and facilities—has a positive and significant effect on visitor loyalty. Furthermore, the simultaneous analysis confirms that the combination of these three factors significantly influences loyalty among visitors to the halal tourism destination. These results align with the Customer Satisfaction Theory, which posits that positive experiences related to service delivery, destination appeal, and the availability of appropriate facilities contribute to higher levels of satisfaction, ultimately fostering loyalty. The implications of this study suggest that halal tourism destination managers should prioritize enhancing service quality, preserving the cultural and historical appeal of attractions, and ensuring the availability of facilities that meet the specific needs of Muslim tourists. By doing so, destinations like Maimun Palace can cultivate sustainable visitor loyalty, which is essential for long-term tourism development and competitiveness in the halal tourism sector. This research contributes to the growing body of literature on halal tourism by empirically validating the role of service, attraction, and facilities in shaping visitor loyalty. Future studies are recommended to explore additional variables such as religious compliance, digital engagement, and cultural sensitivity to provide a more comprehensive understanding of loyalty drivers in halal tourism contexts.

Obesity in women of childbearing age is a growing health problem, not only due to dietary patterns and lack of physical activity, but also due to the influence of social and cultural factors. This study aims to gain a deeper understanding of the experiences, perspectives, and habits of women of reproductive age who are obese within the context of local social and cultural norms. Using a qualitative phenomenological approach, data was collected through in-depth interviews with five primary informants who are obese, as well as triangulation informants from community health workers and healthcare professionals. The results of the study indicate that perceptions of obesity are still predominantly viewed from the perspective of physical appearance rather than health. Social factors such as family eating patterns, snacking habits, comments from others, and lack of physical activity are triggers for obesity. Meanwhile, local culture has a varied influence—some communities are beginning to adopt slim body ideals, while others remain neutral. Obesity also impacts self-confidence, social stigma, and limitations in daily activities. However, most informants expressed hope for a healthier life. This study recommends interventions that consider local cultural values and involve family and community support in obesity prevention effort.

The selection of appropriate solvents in sterile injection formulations plays a pivotal role in determining the stability, efficacy, and safety of pharmaceutical products. Among the commonly utilized solvents, Dimethyl Sulfoxide (DMSO), Polyethylene Glycol (PEG), and pyrogen-free water exhibit distinct physicochemical properties and functional roles. This study aims to analyze the characteristics, functions, and implications of these three solvents within the context of sterile injectable preparations. The research methodology involves a comprehensive review of six peer-reviewed scientific articles published within the last five years, focusing on solvent performance, compatibility, and safety profiles. Findings reveal that DMSO is highly effective in dissolving lipophilic compounds due to its strong solvating capacity. However, its use at elevated concentrations may lead to irritation and cytotoxicity, necessitating careful dosage regulation. PEG, particularly in its flexible molecular weight variants, serves as a co-solvent and viscosity modifier, enhancing solubility and stability of active pharmaceutical ingredients. Pyrogen-free water, characterized by its inertness and biocompatibility, remains the gold standard for injection solvents, offering minimal risk and broad applicability across drug classes. The study underscores the importance of aligning solvent selection with the physicochemical nature of the drug, intended route of administration, and patient safety considerations. Furthermore, the potential for combining solvents to achieve optimized formulations is highlighted as a promising avenue for future pharmaceutical development. Such combinations may offer enhanced solubility, reduced toxicity, and improved delivery mechanisms, particularly for complex or poorly soluble compounds. In conclusion, understanding the nuanced roles of DMSO, PEG, and pyrogen-free water is essential for formulating safe and effective sterile injections. This research contributes to the growing body of knowledge supporting rational solvent selection and encourages further exploration into innovative solvent systems for advanced drug delivery.

This study aims to analyze the effect of variations in body angle on propulsion force and water resistance in swimming athletes through a biomechanical approach. The background of the study is based on the importance of movement efficiency in swimming, where a less than optimal body position can increase the drag coefficient, thereby slowing swimming speed. The research method uses a quantitative experimental design involving professional and semi-professional level swimmers. The instruments used include a motion capture system to record body movements, force sensors to measure propulsion and water resistance, and biomechanical software to analyze force vectors and drag coefficients. The results show significant differences in swimming performance based on variations in body angle. At an angle of 0°, the average propulsion force generated is 145.3 N with a drag coefficient of 0.92. At an angle of 15°, the propulsion force increases to 162.7 N with the lowest drag coefficient of 0.78. Meanwhile, at an angle of 30°, the propulsion force decreases to 150.1 N with the drag coefficient again increasing to 0.88. These findings demonstrate that a 15° body angle is the most optimal position because it minimizes water resistance while maximizing propulsion, thereby increasing swimming efficiency. The implications of this study suggest that a biomechanical approach can be used as a reference in planning swimming training programs. In addition to contributing to the development of sports science, the results of this study also have practical benefits for athletes and coaches in developing more effective training strategies. Future research is recommended to expand the sample size and include various swimming styles to strengthen the generalizability of the results.

The development of science and technology has caused the military forces of many countries to spend a lot of money and energy on research and development of automated, multi-faceted and effective (including lethal) technology. From a maritime perspective, this development has attracted widespread interest from many navies in underwater technology such as submarines and unmanned submarines. Modern submarines are now capable of moving at high speeds with very low noise levels, in addition to being able to carry weapons with very high destructive power and carry out diving operations for long periods of time. At the same time, modern unmanned underwater vehicles are now capable of carrying out various types of operations, including surveillance, minelaying, underwater surveys, and even the ability to carry long-range weapons up to thousands of kilometers away. It is undeniable that the development of other countries' navies is a real threat to Indonesia. To overcome this problem, an underwater surveillance system is needed in Indonesian waters, especially in deep waters which are likely to be used by other countries such as ALKI to carry out covert operations. This underwater surveillance system must utilize existing technological developments in order to carry out its functions effectively and sustainably, especially by using autonomous underwater vehicles (USVs). The use of USV in surveillance systems will save a lot of costs because it does not waste budget on expensive logistics, personnel, maintenance, and spare parts. This research is a research and development using mixed research methods (qualitative and quantitative) with research products in conceptual form. In this underwater surveillance system concept, USV will automatically conduct underwater contact surveillance along the ALKI II water body using sensors and software integrated into the USV.

This journal explores the role of the Church Unity Body in strengthening the unity of Christian faith. The Church, as the body of Christ composed of various members from diverse backgrounds and traditions, is called to unite in one faith, one teaching, and one way of life aligned with the teachings of Christ. This unity is crucial for maintaining harmony within the community of believers and for addressing social and theological challenges in the modern world.The role of the Church Unity Body is evident through Bible teaching based on enduring truth, participation in sacraments such as Holy Communion and Baptism, as well as collaboration among churches in social service and mission. In this context, the church functions not only as a place of worship but also as a community that supports spiritual growth and the well-being of its members. The unity of Christian faith requires mutual respect, forgiveness, and humility among church members. By strengthening this unity, the church can provide a clearer testimony to the world, demonstrating that in Christ, differences can be reconciled in love that transcends all. This article also highlights the importance of the church’s role in building a unity of faith that goes beyond denominational boundaries, within the framework of ecumenism, to realize the wholeness of the body of Christ and bring about transformation in the world.
