In modern soccer, lower-limb power is a crucial component that determines an athlete’s performance in sprinting, kicking, and jumping. This study aimed to compare the effects of Squat jump and Hexagon jump plyometric exercises on lower limb power in youth soccer athletes from Garuda Timur Football Academy Surabaya. The research employed a quasi-experimental method with a pretest–posttest two group design involving 12 athletes aged 14–17 years. Participants were divided into two groups of six: a Hexagon jump group and a Squat jump group. Lower limb power was assessed using the vertical jump test before and after the training intervention. Data were analyzed using the Matched Subject Ordinal Pairing (MSOP) method to determine the relative effectiveness of both training types. The results indicated that both exercises significantly improved athletes’ vertical jump performance. However, the Hexagon jump exercise showed greater effectiveness, with a winning proportion of 67% (4 out of 6 pairs) compared to 33% for the Squat jump. The superior results of the Hexagon jump group were attributed to its multidirectional movement pattern, which provides greater stimulation of coordination, balance, and neuromuscular reactivity. Therefore, it can be concluded that Hexagon jump training is more effective than Squat jump in enhancing lower limb power among youth soccer athletes.

Athletic physical condition is a key factor in determining an athlete's performance during competitions. This study aims to assess the physical condition of Unesa Women FC athletes using a descriptive quantitative method, involving 20 athletes as the sample. Data was collected through a series of physical tests to measure various aspects of physical fitness, including aerobic endurance, speed, agility, leg strength, and explosive power. The tests conducted included the Multistage Fitness Test (MFT) for aerobic endurance, a 30-meter sprint for speed, Illinois Agility Run for agility, Leg Dynamometer for leg strength, and Jump MD for explosive power. The results of the study show that the average VO2Max of the athletes is 30.8 ml/kg/min, which falls into the "Poor" category. This indicates that the athletes' aerobic endurance has not yet reached the optimal standard required for competitive performance. The 30-meter sprint time recorded was 5.53 seconds, categorized as "Good," indicating that the athletes have adequate speed. However, the agility score obtained from the Illinois Agility Run was 21.97 seconds, classified as "Poor," suggesting that the athletes need to improve their agility for quicker movements on the field. The explosive power score, measured by the Jump MD test, was 45.75 cm, which also falls into the "Poor" category, while leg strength, measured using the Leg Dynamometer, resulted in a score of 57.47 kg, classified as "Very Poor." These findings indicate that most components of the physical condition of the Unesa Women FC athletes are still below optimal levels. Therefore, the study emphasizes the need for a more structured and targeted physical training program tailored to the individual needs of each athlete. A training program designed based on these test results will help improve the physical fitness components that are lacking and support the enhancement of their performance during competitions.

Village websites currently generally only provide information in the form of an interface for users, such as village profiles, potential areas, population data, and current news. However, the majority are not yet equipped with Application Programming Interface (API) support that allows for flexible and automated data integration and exchange. This is a challenge when dynamic access is needed by third-party systems, such as public service platforms, mobile applications, or local government information systems, which require real-time and accurate synchronization of population data. The project aims to implement a RESTful API that can be accessed securely, efficiently, and easily understood by developers to retrieve villagers' data. The development of the system is carried out using the Agile method, which supports rapid iteration and periodic evaluation to ensure that each feature functions optimally according to the needs of users and field conditions. This Agile method is applied in several sprints that include the stages of needs planning, designing the API endpoint structure, coding, documentation, and testing of the integration and security of the system as a whole. The results of the implementation show that the API successfully retrieves data directly from the village database, and presents it in a JSON format that is compatible for use by both frontend and third-party systems. This API supports pagination features for efficient access to large amounts of data, and is equipped with Basic Authentication to keep data access secure from being abused. With this API, the village website not only becomes a static information medium, but also transforms into a digital service platform that is open for cross-system integration. This supports the development of a more modern, efficient, sustainable, and collaborative village information system in the future, so that public services can be significantly improved.

This research aims to design and develop a web-based school payment information system using the Agile method at SMK Mutiara Bangsa Cengkareng.The school’s financial management process was still conducted manually using ledgers and spreadsheets, risking data errors and reporting delays.Data collection methods included interviews, observations, and documentation studies.The system was developed iteratively using Agile development cycles, involving stakeholders at each sprint stage.The final result is a web-based application that facilitates payment input, financial reports, transaction history, and role-based access for administrators, staff, teachers, students, and parents.The system improved efficiency, transparency, and accuracy in the school's financial administration.

In the dynamic and exciting technology startup industry uncertainty , management project device soft need approach adaptive and responsive to risk . This study explores synergy between Scrum methods and management risk in increase success project at PT XYZ, a startup that implements the Agile-Waterfall hybrid model. Qualitative methods with studies case and analysis descriptive used for digging practice management integrated risk informally in Scrum processes, such as Sprint planning and retrospectives, with support tool collaborative such as Trello and spreadsheets. The results show This synergy increases identification and mitigation risk , collaboration team , and success project in a way technical and managerial . However , the challenges Still found in the documentation risks and the roles of the Scrum Master and Product Owner that need to be considered reinforced . This study recommends development documentation more standardized risks and strengthening role the key to increasing Agile maturity and resilience projects in the technology startup environment

Sprint or short-distance running is a running event in the sport of athletics that demands maximum speed in a short amount of time. Speed and acceleration are key factors in achieving success in sprint events, making effective training methods essential to enhance athlete performance. This study aims to determine the effect of uphill running training on the speed and acceleration of sprinter athletes in the Athletics Student Activity Unit (UKM) at Universitas Negeri Surabaya. The research uses a quantitative method with a pre-experimental design, specifically the One-Group Pretest-Posttest. The sampling technique used is purposive sampling, with a population of 24 athletes and a sample of 15 male sprinter athletes aged 18-21 years. The instrument used was a 60-meter and 30-meter sprint test, with uphill running training conducted over 6 weeks at a frequency of three times per week. The results showed a significant improvement in the athletes' speed and acceleration after undergoing uphill running training, as evidenced by the t-test results with a significance value of <0.05. Therefore, it can be concluded that uphill running training can positively influence the speed and acceleration of sprinter athletes in the UKM athletics program at Universitas Negeri Surabaya.
