Abstract

Latar Belakang: Daya ledak otot tungkai berperan penting dalam olahraga bola voli, terutama dalam teknik smash yang memerlukan lompatan tinggi. Kurangnya daya ledak otot tungkai dapat menghambat performa atlet dan meningkatkan risiko cedera. Latihan Countermovement Jump (CMJ) dan Calf Raise sering dilakukan guna meningkatkan daya ledak otot, tetapi perbandingan efektivitas keduanya masih belum banyak diteliti. Tujuan: Penelitian ini bertujuan untuk mengetahui perbedaan pengaruh Countermovement Jump dan Calf Raise terhadap peningkatan daya ledak otot tungkai pada atlet voli di Yogyakarta. Metode: Penelitian menggunakan desain quasi-eksperimental dengan metode pre-test post- test control group design. Sampel terdiri dari 22 atlet voli SMA Muhammadiyah 7 Yogyakarta yang dibagi menjadi dua kelompok: Countermovement Jump, dan Calf Raise. Latihan dilakukan selama 4 minggu, dengan frekuensi 3 kali dalam 1 minggu. Pengukuran daya ledak otot tungkai dilakukan menggunakan Vertical Jump Test, dengan analisis data menggunakan paired sampel t-test dan independent sample t-test. Hasil: Kedua latihan menunjukkan peningkatan signifikan terhadap daya ledak otot tungkai (p<0,05). Namun, Countermovement Jump memberikan peningkatan lebih besar dibandingkan Calf Raise. Kesimpulan: Countermovement Jump lebih efektif dibandingkan Calf Raise dalam meningkatkan daya ledak otot tungkai pada atlet voli, sehingga dapat direkomendasikan dalam program latihan atlet.

Abstract

Background: This study compares SNR and CNR in non-contrast head X-rays using Python. Head image quality is crucial due to its complex anatomical structure and the importance of small details in determining a diagnosis. Python is used to objectively analyze image clarity, read medical data, calculate SNR and CNR values, and display the results visually. This research is expected to help physicians obtain clearer images, accelerate diagnoses, and improve the quality of radiology services. Methods: This research was conducted at the Radiology Laboratory of Aisyiyah University Yogyakarta from March to May 2025. The subjects used were not live patients, but rather cranium phantoms, which are artificial models of human heads typically used for training or research to ensure safety. In this study, three different X- ray settings were used: 70 kV 10 mAs, 75 kV 12 mAs, and 80 kV 15 mAs. Each setting produced head X-rays with varying levels of brightness and sharpness. The images were saved in a medical-specific format called DICOM. Next, the images were analyzed using the Python programming language through the Google Colab platform. This analysis was carried out to calculate two important things: SNR (Signal-to-Noise Ratio), which describes how clear the image signal is compared to interference or "noise," and CNR (Contrast-to-Noise Ratio), which indicates how easy it is to distinguish two tissues or parts in the image. This calculation was carried out both before and after the image was improved through the image enhancement process. In this way, researchers can assess whether image processing actually makes head X-rays clearer and more useful for medical diagnosis. Results: The results showed that after image processing with Python, the SNR values increased in some settings, resulting in cleaner images, but the CNR values decreased in all images. This means that although the images appear sharper and clearer visually, the ability to distinguish anatomical structures is reduced. Therefore, improving visual quality through image enhancement does not always translate into improved diagnostic quality, requiring caution when applying it to radiology. Conclusion: The conclusion of this study is that processing non-contrast head radiographic images using Python can improve the SNR value in several parameter variations, so that the image appears cleaner from noise interference. However, the CNR value tends to decrease in all variations, which means the ability to distinguish anatomical structures is reduced. This shows that increasing visual acuity of the image is not always directly proportional to improving diagnostic quality, so image enhancement techniques need to be applied carefully to maintain a balance between image clarity and clarity of anatomical details to support medical diagnosis

Abstract

Background: Background: VO2 max or maximal oxygen volume is the main indicator of a person's aerobic capacity and has a vital role in athlete performance, especially in soccer. Therefore, developing VO2 max is a key component in modern soccer training programs. Physiotherapy interventions through skipping exercises and interval training are non-pharmacological approaches that can be used to increase VO2 max effectively. Research Objective: To determine the differences in the effects of skipping exercises and interval training on increasing VO2 max in soccer players. Method: This study is an experimental quantitative study with a pre-test and post-test control group design. The sample consisted of 22 male respondents from Baturetno Football School students who were divided into two groups (11 respondents each). The intervention was carried out 3x a week for 4 weeks. VO2 max data were collected using the Multi Stage fitness test (MFT). Statistical tests using Paired Sample T-Test and Independent Sample T-Test. Results: Hypothesis I and II tests using paired sample t-test showed that there was an effect of skipping and interval training on increasing VO2 max in soccer players (P = 0.00 P <0.05). Hypothesis III tests using independent sample t-test showed that interval training had a greater effect than skipping training on increasing VO2 max in soccer players. (P = 0.008 P <0.05). Conclusion: interval training had a greater effect than skipping training on increasing VO2 max in soccer players. Suggestion: Further research is expected to conduct further analysis on other, more varied exercises to increase VO2 max in soccer players

Abstract

Background: Head CT Scans for hemorrhage cases at the Radiology Unit of Aisyiyah Ponorogo Hospital use an automated volumetric method to calculate the volume of bleeding. This process involves segmenting the bleeding area, and the volume results are immediately available without manual calculations. Unlike some studies that suggest automated methods require more time, this method was chosen at Aisyiyah Ponorogo Hospital because it utilizes multislice  CT Scanning technology, which allows for faster and more accurate estimation of the volume of bleeding. Methods: This study employed a descriptive qualitative approach with observation, interviews, and documentation techniques. The subjects included three radiographers and one radiologist. The study took place at the Radiology Unit of Aisyiyah Ponorogo General Hospital from March to July 2025. Data were collected through direct observation, in-depth interviews, image documentation, and literature review. Data analysis was conducted through transcription, categorization, and narrative presentation based on the research focus. Results: There are differences in the preparation of tools and materials used in bleeding cases. Calculating bleeding volume using automated segmentation-based methods still requires manual involvement and precision in shading the bleeding volume. However, automated methods remain superior because they reduce subjectivity between operators and provide consistent, measurable, accurate, efficient, and reproducible results. Calculating bleeding volume using automated methods is particularly helpful in emergency situations, where clinical decisions must be made quickly. Conclusions: Head CT Scans for hemorrhage cases have not optimized the use of head straps and blankets. The use of blankets and head straps can provide comfort and reduce movement during the examination. Automatic segmentation-based hemorrhage volume calculation improves work efficiency, result consistency, and diagnostic accuracy, while reducing the potential for subjective errors similar to manual methods. This method has nearly perfect agreement with manual methods (coefficient of 0.99), making it worthy of inclusion in medical assistive technology

Abstract

Background: Head CT scans performed at the Pediatric Radiology Unit of Temanggung Regency Hospital use the adult head protocol (Head Helical). This differs from the theory that specific head protocols are required for each age group. The purpose of this study was to determine the pediatric head CT scan procedure at the Radiology Unit of Temanggung Regency Hospital, the rationale for using the adult head CT scan protocol for pediatric head CT scans, and the radiation protection measures implemented during pediatric head CT scans. Methods: This study employed a descriptive qualitative method with a case study approach. Data were collected through observation, interviews, documentation, and literature review at the Radiology Unit of Temanggung Regency Hospital. Subjects included three radiographers and one radiation protection officer, with the pediatric head CT scan procedure as the object of the study. Data were analyzed through observation, interviews, and documentation. Interview results were transcribed and then summarized using a categorization table. The summarized data were presented in narrative form and explained with a theoretical basis to draw conclusions. Results: Pediatric head CT scans performed at the Radiology Department of Temanggung District Hospital used the adult protocol (Head Helical) without modifications based on age classification. Parameters such as tube voltage (120 kV) and current (300 mAs) were the same for infants and children, resulting in CTDIvol (78.1 mGy) and DLP values exceeding the BAPETEN IDRL standard. Although diagnostic imaging results were considered good, the risk of high radiation exposure remains a concern. Several reasons for the lack of protocol adjustments for pediatric head CT scans include: habit, timeliness, culture, and prioritizing good image quality. Radiation protection for patients and caregivers was implemented according to standards, including the use of aprons and educational procedures. Conclusion: The procedure was largely in accordance with theory from a technical and protective perspective, but the use of the adult protocol without adjustments increases the risk of overdose in pediatric patients. Periodic evaluation and implementation of pediatric-specific protocols based on the ALARA principle are strongly recommended for pediatric patient safety

Abstract

This study examines the strategic involvement of Osing youth in preserving local culture through their participation in the Gandrung Sewu Festival in Banyuwangi. This annual festival functions not only as an artistic performance but also as a medium for transmitting Osing cultural values and promoting culture-based tourism. Employing a descriptive qualitative approach framed by theories of social participation, cultural transmission, cultural tourism, and cultural festivals as preservation and promotion tools. The research explores various forms of youth involvement, ranging from dancers, organizing committees, and art facilitators to digital promoters. The findings reveal that youth participation is predominantly symbolic, although creative initiatives have emerged, such as the Gandrung Anak Muda community, which utilizes social media and digital content innovation. Key driving factors include cultural identity and community support, while challenges consist of limited training, inadequate cultural facilities, and the influence of popular culture. The study underscores the importance of engaging young generations in all stages of sustainable cultural preservation. The Gandrung Sewu Festival holds significant potential as an educational platform and as a driver of culture-based creative economy. Recommendations are directed toward strengthening digital strategies, fostering early cultural education, and implementing participatory cross-generational policies

Abstract

Sustainable tourism development poses a significant challenge for local governments in maintaining a balance between economic, social, and environmental interests. However, the multiple roles played by local governments often face structural and operational obstacles. This study aims to critically examine how the Karanganyar Regency Government fulfills its roles as a motivator, facilitator, and dynamizer in promoting sustainable tourism in the Tawangmangu tourism area. This research employs a qualitative approach using a case study strategy, collecting data through in-depth interviews, participatory observation, and documentation involving informants from government agencies, tourism managers, business actors, and tourists. Data analysis follows the interactive model of Miles, Huberman, and Saldana. The findings indicate that the facilitator role is the most dominant in tourism development efforts, while the roles of motivator and dynamizer are present but not yet optimal. Supporting factors include natural potential, local cultural richness, and policy support, while the main obstacles consist of limited budget allocation, weak cross-sector coordination, and low public awareness of environmental issues. The study concludes that strengthening multi-stakeholder collaboration and integrating cross-sectoral policies are strategic steps to ensure the sustainability of tourism in Tawangmangu
