A suitable and targeted marketing plan is required because of the intense competition in the retail drinking water sector. Customer segmentation using RFM (Recency, Frequency, and Monetary) analysis is one of the techniques employed. Additionally, K-Means clustering, a clustering technique based on machine learning, is employed. This study's goal is to present the findings in the form of graphs that can be used to examine consumer trends according to their attributes. With a value of 10286, the Calinski Harabaz index is a suitable metric to move on to the segmentation step in this study, which also tests three metrics using the clustering method. An ideal cluster is created for every cluster evaluation by dividing the Calinski Harabaz index into three more manageable clusters. This contrasts with other evaluation metrics that only yield two clusters. For instance, when XYZ drinking water sales transaction data was distributed, it was discovered that, out of the total drinking water sales, woodsale had 422 customers, diamond had 1061 customers, and star diamond had 2005 customers. The management of the XYZ drinking water company and other marketing fields are expected to encounter more intense competition as a result of the study's findings.

Air pollution constitutes a significant environmental problem with far-reaching impacts on public health, quality of life, and ecosystem sustainability, particularly in urban areas and industrial zones in Indonesia. Although the national environmental legal framework has adopted the principle of strict liability through Law Number 32 of 2009 on Environmental Protection and Management, its implementation in air pollution cases continues to face substantial challenges, especially with regard to the proof and assessment of non-material damages. Non-material damages such as disturbances to living comfort, deterioration of environmental quality, psychological stress, and health-related anxiety are intangible in nature and lack clear measurement standards, resulting in their frequent exclusion or inadequate consideration in environmental civil litigation. This study aims to analyze the legal basis for the application of the strict liability principle to air pollution cases in Indonesia, identify relevant forms of non-material damage, and examine the implications of the absence of standardized methods for assessing such damages on legal certainty and the effectiveness of corporate liability enforcement. The research employs a normative legal research method with a library-based approach, incorporating statutory, conceptual, and case approaches. Legal materials are analyzed qualitatively using a descriptive-analytical method, drawing upon legislation, court decisions, and scholarly literature on environmental law and environmental damage valuation. The findings indicate that the absence of standardized criteria for assessing non-material damages leads to evidentiary difficulties, inconsistent court decisions, and a weakened deterrent effect on polluting corporations, thereby preventing the full realization of victims’ rights to effective remedies. This study underscores the urgency of developing an integrated national technical guideline for the assessment of non-material environmental damages based on scientifically grounded valuation methods, as well as the need for cross-institutional policy harmonization to strengthen legal certainty, access to justice for affected communities, and corporate accountability in controlling air pollution.

Exercise is a planned physical activity that not only contributes to physical fitness but also plays a significant role in maintaining and improving mental health. This study aims to explore the relationship between physical exercise and mental well-being among adolescents and university students with diverse backgrounds of physical activity. The research employs a qualitative approach using in-depth interviews with five informants, consisting of university students who engage in recreational exercise, recreational runners, middle- and long-distance runners, and a sprinter. Data collection was conducted in several public sports spaces in the city of Bandung, focusing on participants’ subjective experiences related to their psychological conditions before and after engaging in exercise. The findings indicate that all participants perceive exercise as an effective means of emotional regulation. Physical activity is consistently associated with improved mood, reduced stress, enhanced sleep quality, stable energy levels, and increased academic concentration and focus. In addition, exercise contributes to the development of self-confidence, self-efficacy, and self-control through structured routines. The social aspects of exercise, such as support from peers, communities, and coaches, were shown to strengthen the sustainability of physical activity while also providing essential emotional support for mental health. However, among competitive athletes, performance-related pressure was identified as a factor that may negatively affect psychological well-being, although this effect can be moderated by adequate social support. Overall, the findings of this study emphasize that exercise functions as an adaptive coping mechanism operating through biological, psychological, and social pathways, and highlight the importance of consistency and balance in physical activity to achieve optimal mental health benefits.  

Tuberculosis (TB) is a contagious disease of the respiratory system that remains a global public health problem, including in Indonesia, with high incidence rates among adolescents due to intense social activities and interactions. This community service activity aims to increase adolescents' knowledge about TB from an epidemiological perspective, including modes of transmission, symptoms, risk factors, and prevention efforts as an airborne disease. The method used was a quasi-experimental approach with a two-group pretest-posttest design, through health education provided to 149 adolescents aged 15–17 years at Darussalam High School in Medan. Data collection was conducted using questionnaires to assess the level of knowledge before and after the educational intervention. The results of the activity showed a significant increase in the level of knowledge after the education was provided, where the percentage of respondents in the high knowledge category increased from 82% in the pre-test to 93% in the post-test, accompanied by a decrease in the sufficient and low knowledge categories. This study shows that community service activities through health education have a significant effect on increasing adolescents' knowledge about tuberculosis. Health education has been proven to be effective as a promotional and preventive measure, so it needs to be implemented continuously to prevent the transmission

Clean water quality is an important factor in supporting public health. In Kaliwader Village, Bener District, Purworejo Regency, drilled well water is used as the main source of clean water, however, based on initial testing, discrepancies were still found in several water quality parameters, particularly turbidity. The Community Service Lecture (KPM) activity of the Al-Qur'an Science University (UNSIQ) aims to improve the quality of drilled well water through the implementation of a water filtration system combined with a venturi aerator and providing education to the community about clean water management. The method used is a descriptive method with an observational approach, including water sampling, laboratory testing at the Regional Health Laboratory UPT, and the implementation of a Malang sand-based filtration unit with venturi aeration. The test results showed that the water turbidity level before treatment reached 8 NTU, exceeding the established quality standards. After the implementation of the filtration system and venturi aerator, the physical quality of the water improved, marked by a decrease in turbidity and an increase in water clarity. Chemical and microbiological parameters were generally within safe limits according to the Regulation of the Minister of Health of the Republic of Indonesia Number 2 of 2023. This activity demonstrated that the application of simple technology by UNSIQ KPM students can play an effective role in improving the quality of drilled well water and supporting the provision of more adequate clean water for the people of Kaliwader Village.

Nature-based tourism development has a strategic role in encouraging sustainable local economic growth, especially in rural areas such as Marente Village, Kabupaten Sumbawa. Agal Waterfall is one of the natural tourism destinations that has high attractiveness, but its utilization is still not optimal due to limited facilities and infrastructure, access to the location, promotional activities, and the quality of human resources management. This study aims to identify strengths, weaknesses, opportunities, and threats, and determine priority strategies in developing Agal Waterfall tourism using the Quantitative Strategic Planning Matrix (QSPM) method. The research approach used is descriptive quantitative with primary data collected from 100 respondents. Analysis techniques include the preparation of IFAS, EFAS, SWOT, and QSPM matrices. The research findings show that the beauty of the natural environment and community participation are the main strengths, while the limited supporting facilities and promotion are still the dominant weaknesses. Development opportunities are supported by the increasing interest in nature tourism and the utilization of digital platforms, while threats come from competition between tourist destinations and the potential for environmental degradation. Based on the results of the analysis, priority strategies suggested include improving basic facilities, optimizing digital-based promotions, strengthening the capacity of human resource managers, and implementing the principles of sustainable tourism.

Organic and inorganic waste is often left to accumulate behind the school or burned, which can cause air pollution and threaten the health of the surrounding environment. This study aims to determine the effectiveness of health promotion media on students' knowledge and attitudes about waste management at SMP Negeri 6 Birem Bayeun, East Aceh Regency.

Severe preeclampsia is a condition characterized by systolic blood pressure exceeding 160 mmHg and diastolic pressure exceeding 110 mmHg, occurring after 20 weeks of gestation and accompanied by edema and proteinuria. One intervention used to save both mother and fetus is a cesarean section. This final nursing scientific paper analyzes the implementation of evidence-based practice, specifically warm foot soak therapy, for mothers with severe preeclampsia during the pre- and postpartum periods who are at risk for ineffective cerebral perfusion. This descriptive case study method used a nursing care approach. Assessment results identified five major nursing problems, including the risk for ineffective cerebral perfusion. After four days of warm foot soak therapy, this problem was resolved, as blood pressure decreased from 147/101 mmHg to 120/88 mmHg. Conclusion: Warm foot soak therapy effectively lowers blood pressure in pre- and postpartum mothers with severe preeclampsia. Recommendation: Nurses can implement warm

This study examines the seismic performance of slender Air Traffic Control (ATC) towers in high‑hazard regions (PGA > 0.4g), where vertical taper, torsional eccentricity, and top‑heavy cab mass can significantly increase drift, base shear, and collapse risk relative to conventional buildings. Existing studies often rely on linear procedures and outdated provisions, leading to underestimation of nonlinear behaviour and limited guidance for ATC towers designed to SNI 1726:2019. The research aims to quantify these irregularity effects and formulate design recommendations that satisfy Immediate Occupancy, Life Safety, and Collapse Prevention performance targets. The methodology couples response spectrum analysis, using a site‑specific Padang spectrum consistent with SNI 1726:2019 and ASCE 7‑16, with nonlinear pushover analysis interpreted through FEMA/ATC performance‑based criteria. A parametric study is performed on three cab configurations small, medium, and large modelled as 5%, 15%, and 25% mass ratios at the tower head, while keeping a 10 m × 10 m hybrid core–frame shaft constant. Results indicate that larger cab mass produces systematic but moderate increases in global displacement, story drift, and base shear, while plastic hinges localize primarily in the upper stories and cab‑support region, yielding performance levels from Immediate Occupancy to Collapse Prevention. Overall, the tower meets code drift limits and acceptable performance if local strengthening is provided around the shaft–cab interface, offering a calibrated reference for top‑heavy ATC tower design in Indonesian high‑seismic settings and identifying priorities for future time‑history and soil–structure interaction studies.

Penelitian ini mengkaji simbol air dalam Injil Yohanes sebagai bahasa wahyu yang mengungkapkan identitas ilahi Yesus dalam kerangka pneumatologi. Latar belakang penelitian ini adalah adanya kecenderungan studi sebelumnya yang menafsirkan simbol air secara parsial, baik sebagai simbol sakramental maupun metafora spiritual, tanpa melihat keterkaitannya secara menyeluruh dalam struktur naratif Injil Yohanes dan tradisi Yahudi. Tujuan penelitian ini adalah untuk menunjukkan bahwa simbol air merupakan struktur teologis yang mengintegrasikan kristologi, dan pneumatologi  Yohanes. Metode yang digunakan adalah pendekatan kualitatif dengan jenis studi kepustakaan, melalui analisis teologis-intertekstual terhadap teks-teks Yohanes yang berkaitan dengan simbol air serta hubungannya dengan Perjanjian Lama dan tradisi Yahudi. Hasil penelitian menunjukkan bahwa simbol air berkembang secara progresif dari makna literal menuju simbol kehidupan ilahi dan Roh Kudus, serta mencapai klimaks dalam peristiwa penyaliban sebagai pencurahan Roh dan kelahiran Gereja. Dengan demikian, air berfungsi sebagai medium pewahyuan yang tidak hanya menjelaskan karya keselamatan, tetapi juga mengungkapkan identitas Yesus sebagai sumber kehidupan ilahi. Implikasi penelitian ini menegaskan bahwa pneumatologi Yohanes pada dasarnya merupakan ekspresi kristologi dalam bahasa simbolik.

In demographic studies, population growth refers to changes in the number of inhabitants over a given period, measured by calculating numerical differences in population size and expressing them within specific time units to illustrate patterns of increase or decline. Based on data from Tembalang District in Figures 2025, the population growth rate in Kedungmundu Village rose by 0.51% between 2016 and 2025, with most residents relying on clean water services provided by PDAM Tirta Moedal as their primary source of drinking water. This study aims to estimate clean water demand based on projected population growth and to design a pipeline network system capable of meeting future needs. The analysis of water demand applies population projection methods, including arithmetic, geometric, and least square approaches, to compare their levels of accuracy, while the clean water distribution network is modeled using EPANET 2.0. One of the main challenges faced by PDAM is that service coverage has not yet been fully optimized. The ten-year projection results indicate that the arithmetic method provides a correlation value closest to 1, estimating a future population of 14,904 people with a total clean water requirement of 3.48 liters per second. To support this projected demand, the proposed network design utilizes High Density Polyethylene (HDPE) pipes with diameters of 12, 10, and 8 inches to ensure efficient and sustainable water distribution.

Emergency conditions refer to situations that require immediate intervention because they have the potential to threaten life, impair organ function, or cause disability if not managed promptly and appropriately. Status epilepticus is a neurological emergency defined by seizures lasting five minutes or longer, or by repeated seizures without regaining consciousness between episodes. Status epilepticus can develop in individuals both with and without a previous diagnosis of epilepsy and may result from a wide range of causes, such as metabolic abnormalities, infections of the central nervous system, stroke, head injury, sudden discontinuation of antiepileptic medications, and alcohol intoxication or withdrawal. Clinically, this condition is classified into convulsive and non-convulsive status epilepticus. The diagnosis is primarily clinical and must be established rapidly, while electroencephalography plays an important role, particularly in cases of non-convulsive status epilepticus. Management emphasizes initial stabilization of the airway, breathing, and circulation, after which benzodiazepines are given as first-line treatment, including intramuscular midazolam, intravenous lorazepam, or intravenous diazepam. Status epilepticus represents the most severe form of seizure activity, characterized by continuous, unremitting seizures accompanied by strong muscle contractions, respiratory compromise, and widespread abnormal electrical activity in the brain. If not treated promptly, the risk of permanent brain tissue damage increases and the condition may ultimately lead to death.

The Tapal Kuda Air Salobar Food Court is one of the culinary areas that plays an important role in supporting tourism and social activities in Ambon City. This area offers a variety of local culinary specialties from Maluku which are an attraction for the community and tourists. However, the increase in the number of visitors and the activities of traders have not been fully balanced by the conditions of adequate spatial planning, facilities, and area management systems. This study aims to analyze the existing condition of the Tapal Kuda Air Salobar Food Court from the aspects of spatial planning, waste management, supporting facilities, as well as the potential and challenges of its development as a culinary tourism destination. This study uses a descriptive qualitative approach with data collection methods in the form of field observations and in-depth interviews with key informants, namely area managers, traders, and visitors. The data obtained are analyzed thematically to identify the main problems and potential development of the area. The results of the study indicate that the spatial planning of the Tapal Kuda Air Salobar Food Court has not been able to accommodate the increase in visitor and trader activities due to the lack of clear zoning, limited circulation routes, and spatial planning that develops without integrated planning. Furthermore, waste management in this area is not yet systematic and sustainable, as evidenced by limited trash bins, a lack of waste sorting, and poorly scheduled waste collection. Limited supporting facilities, such as seating and sanitation facilities, also impact the comfort and quality of the visitor experience, especially during peak visitor periods. Nevertheless, the Tapal Kuda Air Salobar Food Court has significant potential as a culinary tourism destination based on local cuisine and a social space, which can be developed through spatial planning, facility improvements, and more integrated area management. This study concludes that the revitalization of the Tapal Kuda Air Salobar Food Court requires a comprehensive approach, emphasizing spatial planning improvements, strengthening waste management, and enhancing the quality of facilities and area management to support the sustainability of culinary tourism and the quality of public spaces in Ambon City.

The increasing intensity of traffic object movement in urban areas has not been accompanied by adequate road infrastructure, resulting in traffic congestion, air pollution, and a higher risk of traffic accidents. One of the primary causes of accidents is traffic violations, particularly wrong-way driving behavior. This study develops a video-based automated traffic violation detection system using the YOLOv5 algorithm. A computer vision approach is employed to detect, classify traffic objects, and count wrong-way violations in real time. Due to limited access to real-world traffic violation footage, simulated traffic scenarios are used as testing data. The system is evaluated on four traffic object classes: motorcycles, cars, buses, and trucks. Experimental results demonstrate strong performance, achieving a precision of 90%, a recall of 92%, and an F1-score of 91%, while the traffic object counting accuracy reaches 89%. These findings indicate that the proposed system has significant potential to support traffic analysis and assist authorities in making more effective decisions to reduce congestion and traffic accidents.

This community service initiative provides a comprehensive business analysis to evaluate financial feasibility, aiming to mitigate potential losses and ensure operational viability. By offering concrete data on business prospects and challenges, this analysis serves as a strategic guide for resource allocation and market targeting, while simultaneously enhancing attractiveness to potential investors. The program was conducted in the South Nunukan District, Nunukan Regency, North Kalimantan. As Indonesia's 34th province and a strategic border region, North Kalimantan faces significant challenges in food security due to limited supply chains. A central component of this study is the Break-Even Point (BEP) analysis—the threshold at which a business incurs neither profit nor loss. The BEP analysis provides critical insights into the relationship between pricing, operational costs, sales volume, and production levels. Consequently, it serves as a vital decision-making tool for business owners to optimize profitability. The results of this study demonstrate that, despite the continued use of traditional methods, the polyculture system remains highly profitable and sustainable for the local community.

Hemangioma is the most common benign vascular tumor in infancy and is generally characterized by a proliferative phase followed by spontaneous involution. Although most cases resolve without intervention, treatment is required when hemangiomas cause functional impairment, ulceration, or life-threatening complications. Lingual hemangioma is a rare presentation and may result in significant feeding difficulties and airway compromise, requiring prompt and multidisciplinary management. This study aims to report the comprehensive management of a refractory lingual hemangioma in an infant, emphasizing diagnostic evaluation, therapeutic strategy, and nutritional support. A six-month-old female infant presented with a lingual hemangioma associated with progressive feeding difficulties. Prior to initiating therapy, a thorough diagnostic workup was performed, including echocardiography to assess cardiac function, magnetic resonance imaging (MRI) to evaluate lesion extent, and computed tomography angiography (CT-angiography) to delineate vascular anatomy. The patient initially received oral propranolol as first-line therapy; however, due to an inadequate response, combination chemotherapy with Bleomycin–Vincristine (BV) was initiated. To minimize the risk of toxicity, a 50% dose reduction was applied. Clinical evaluation demonstrated a favorable therapeutic response, with a reduction in lesion size and improvement in feeding ability after 10 weeks of treatment. No severe adverse effects were observed during the treatment period. To ensure adequate nutritional intake and support growth, enteral nutrition via a nasogastric tube (NGT) was provided throughout the course of therapy. This case highlights the importance of comprehensive diagnostic assessment, individualized treatment planning, and close monitoring in refractory hemangioma. In addition, optimal nutritional support plays a crucial role in overall patient outcomes. A multidisciplinary approach is essential for the successful management of complex infantile hemangiomas with functional complications.
