Postoperative Total Knee Replacement (TKR) patients often face various clinical problems, including quadriceps muscle weakness, limited range of motion of the knee joint, swelling, and pain that can have a significant impact on functional movement ability, independence of daily activities, and overall quality of life. The condition demands the role of the physiotherapist in providing appropriate and comprehensive interventions to facilitate the patient's recovery. One approach that can be done is to provide a combination of Neuromuscular Electrical Stimulation (NMES) modalities and exercise therapy. This study aims to evaluate the benefits of NMES and exercise therapy combination interventions in improving quadriceps muscle strength, knee joint range of motion, and functional mobility ability in post-TKR patients. The research design used a case study method involving three patients who were in phase 2 (motion phase), namely 3 days to 6 weeks after TKR surgery. Patients show complaints in the form of weakness of the quadriceps muscles, limited range of joint movement, and decreased knee function function. Physiotherapy interventions were given as many as 8 meeting sessions with a frequency of 2 times a week. The intervention program consisted of administering NMES to the quadriceps muscle and functional exercises such as sit to stand exercise, gait training, strengthening exercises using resistance bands in the ankle joint, and stair climbing. The results showed a significant increase in quadriceps muscle strength, an increase in the range of motion of the knee joint, and an improvement in functional movement ability after all intervention sessions were completed. These findings confirm that the combination of NMES with exercise therapy can be an effective rehabilitation strategy for post-TKR patients. The implementation of this method has the potential to speed up recovery, reduce dependence on others, and improve the patient's quality of life in a sustainable manner.

Carpal Tunnel Syndrome (CTS) is one of the most common musculoskeletal disorders experienced by office workers. This condition generally arises from repetitive wrist activities, such as prolonged typing or intensive mouse use, which cause pressure on the median nerve. Symptoms of CTS include pain, tingling, weakness, and decreased hand function, which can interfere with work productivity. Various conservative interventions have been developed, one of which is nerve gliding exercises, which mobilize the median nerve to reduce pressure, improve blood flow, and facilitate nerve movement within the carpal canal. This study aims to narratively review the effectiveness of nerve gliding exercises in improving the functional abilities of CTS patients, particularly in office workers. The method used was a systematic literature review of 16 international articles published between 2016 and 2024, using randomized controlled trial (RCT) and quasi-experimental designs. Articles were selected based on inclusion criteria, which included the primary intervention of nerve gliding exercise in CTS patients, measurement of hand function using the Boston Carpal Tunnel Questionnaire (BCTQ), and parameters of grip strength and range of motion. The analysis showed that nerve gliding exercise consistently resulted in significant improvements in grip strength, wrist range of motion, and reduced disability scores on the BCTQ. Several studies also reported reduced pain complaints and improved quality of life in patients after 4–8 weeks of regular intervention. Furthermore, the combination of nerve gliding exercise with other modalities, such as ultrasound therapy, low-level laser therapy (LLLT), or the use of wrist splints, has been shown to produce more optimal effects than either intervention alone. These findings support the belief that nerve gliding exercise is an effective, simple, inexpensive, and easily applicable therapeutic strategy for CTS patients, particularly high-risk office workers.

The Public-Private Partnership (PPP) scheme with guarantees from PT PII aims to accelerate infrastructure development through private participation, but faces legal and practical challenges, particularly related to the risk of default by the Government and Construction Service Provider (GCA) and the effectiveness of the implementation of recourse rights by PT PII towards government institutions. This study uses a normative juridical method with an analytical descriptive approach through a literature study of primary and secondary legal materials, as well as a qualitative analysis of legal documents, to understand in depth the application of recourse rights to GCA in the PPP mechanism. The application of recourse rights by PT PII as a PPP project guarantor is based on a special legal framework and complex contractual agreements to protect investors from the risk of default by the GCA. However, its implementation has the potential to face legal, political, bureaucratic, and fiscal challenges that can affect the effectiveness of protection and the fiscal sustainability of PT PII. PT PII's recourse rights in the PPP scheme are an adaptation of the borgtocht concept applied lex specialis through the PPP agreement, guarantees, and recourse to protect state finances. However, its implementation faces bureaucratic, budgetary, and fiscal constraints that can hamper its effectiveness. Therefore, binding guidelines and increased institutional capacity are needed to ensure that regress rights can be exercised effectively, accountably, and in accordance with the principles of transparency and accountability. This study concludes that to increase the effectiveness of the PPP scheme, improvements in the legal framework, inter-agency coordination, and strengthening the capacity of institutions involved in implementing regress rights are needed.

Obesity, central obesity, and hypercholesterolemia are prevalent yet often unrecognized health conditions that significantly elevate the risk for various non-communicable diseases (NCDs) such as diabetes mellitus, hypertension, and cardiovascular disorders. These conditions, when left undiagnosed and untreated, contribute to the growing public health burden worldwide. This community service program was designed to raise awareness and provide early detection of these conditions through basic health screening measures, including body mass index (BMI), waist circumference, and blood cholesterol levels. The program was implemented in Tomang Subdistrict, West Jakarta, where 90 participants were involved. The findings from the screening revealed concerning results: 67% of the participants were classified as obese, and 58% had central obesity, both of which are major risk factors for NCDs. A deeper analysis of lifestyle factors highlighted that high-fat diets, sedentary behaviors, and night shift work were significant contributors to the high rates of obesity and metabolic abnormalities observed. The educational outreach component of the program, which included the provision of information about healthy diets, exercise, and the importance of regular health screenings, proved to be effective in raising awareness about these health issues. Moreover, the simple health screening process was well-received by the community and contributed to a greater understanding of individual health risks. This initiative is expected to serve as a sustainable model for promoting health and preventing metabolic diseases in the community. The findings underscore the importance of early detection and education as critical strategies in the fight against obesity and related NCDs, suggesting that such programs can play a key role in reducing the future burden of chronic diseases in underserved populations

The agricultural sector plays a crucial role in fulfilling food needs, but it continues to face several challenges, including limited land, climate change, and the need for more cost-efficient production methods. To address these challenges, the application of Artificial Intelligence of Things (AIoT) technology emerges as a promising solution to enhance productivity and efficiency in farm management. AIoT technology integrates artificial intelligence (AI) and the Internet of Things (IoT), enabling smarter decision-making, automation, and real-time data analysis in agricultural practices.

This community service activity was carried out with the primary objective of improving the Qur'an reading skills of the women of the Majelis Taklim (Islamic study group) through systematically designed intensive training. Reading the Qur'an properly and correctly is an obligation for every Muslim, but in reality, many people, especially the women of the Majelis Taklim (Islamic study group), still face obstacles in aspects of makhraj, tajwid, and fluency. This condition encourages the need for a targeted coaching program to improve the quality of Qur'an reading, so that the values ​​of Islamic teachings can be understood and practiced more accurately. The training was held in early July 2025 with a total of 35 participants from the Majelis Taklim (Islamic study group) with diverse reading ability backgrounds. The methods used included lectures, demonstrations, reading practice, individual guidance, and ongoing evaluation at each meeting. This approach was chosen so that participants not only gain theoretical knowledge but also practical skills that can be immediately applied. Evaluation was carried out through observing reading ability, courage to ask questions, and active participation in group exercises. The results of the activity showed a significant improvement in the participants' Qur'an reading skills, both in terms of letter pronunciation, application of Tajweed rules, and fluency in reading holy verses. The participants' enthusiasm was evident in their eagerness to participate in all sessions, their sincerity in practicing, and their active interaction during the learning process. Furthermore, this activity also fostered new motivation for participants to continue improving their reading quality independently and create a conducive learning environment in the Islamic study groups. Thus, this training proves that the right learning strategy, supported by high motivation from participants, can have a positive and sustainable impact on improving the quality of Quran reading. It is hoped that this type of program can be replicated in other Islamic study groups so that its benefits are even broader for the community.

Hypertension is a chronic disease characterized by persistently elevated blood pressure. This condition occurs when the arteries narrow, obstructing blood flow and increasing pressure on the vessel walls. As a result, the heart is forced to work harder to pump blood throughout the body. If this condition is not properly controlled, it can lead to serious complications such as damage to the blood vessels, heart, kidneys, and even the brain. Therefore, effective management of hypertension is crucial, not only with pharmacological treatment but also through non-pharmacological interventions such as regular exercise. One recommended form of light exercise is brisk walking, which involves brisk walking at moderate intensity. This exercise is known to reduce peripheral resistance when the body's muscles contract, which in turn helps control blood pressure and increase cardiac output. This case study aims to determine the effectiveness of brisk walking therapy on the risk of decreased cardiac output in hypertensive patients. The intervention was carried out on hypertensive patients through home visits three days a week, with one meeting each morning. Patients were given brisk walking therapy with a specific duration and intensity according to their condition. Evaluation was carried out by measuring blood pressure before and after the intervention using a standard observation sheet. After three interventions, there was a significant decrease in blood pressure in patients. This indicates a positive effect of brisk walking on the cardiovascular system of hypertensive patients. Brisk walking is an effective and easy-to-do non-pharmacological therapy to help lower blood pressure and reduce the risk of decreased cardiac output in hypertensive patients. It is hoped that this therapy can become part of a self-help intervention carried out continuously in the patient's home environment.

The purpose of this community service (PkM) is to provide Mindfulness training to ANANDA PAUD teachers in RW.19 to improve their understanding of themselves regarding their physical and psychological well-being. Mindfulness training is a meditation method used to increase empathy both affectively, cognitively, morally, intrapersonally and interpersonally.

Futsal is a high-intensity team sport that requires a combination of speed, agility, and physical endurance, particularly cardiorespiratory endurance. Cardiorespiratory endurance is crucial because it directly relates to a player's ability to maintain optimal performance throughout a match, particularly when facing fast-paced and stressful play. Therefore, variables that can influence this ability, such as body composition and nutritional status, are crucial in developing athlete performance. One indicator that can be used to measure nutritional status and body composition is the Body Mass Index (BMI), which is obtained by measuring weight and height. BMI not only reflects whether a person is within the ideal weight range but also potentially influences the efficiency of the body's organs, including the cardiovascular and respiratory systems. In the context of futsal, players with a higher BMI tend to have a higher body weight, which can hinder movement efficiency and increase fatigue during matches. Conversely, players with a lower BMI may have insufficient energy reserves and muscle mass to maintain stamina during matches. This study shows a significant negative relationship between BMI and cardiorespiratory endurance in futsal players at Bali International University. The results of statistical tests using the Spearman rank correlation method showed a correlation coefficient (r) of -0.504 with a significance value of p = 0.005. This indicates that the higher a player's BMI, the lower their cardiorespiratory endurance tends to be. These findings support the importance of ideal body weight management in futsal athlete training, both through dietary adjustments and measured physical exercise programs.

This study examines the role of discretion exercised by law enforcement officers, especially within the context of criminal investigations. Discretion refers to the authority granted to investigators, prosecutors, and judges to make decisions that are not always explicitly regulated by written laws or regulations. It is granted to allow flexibility in addressing situations that require quick, context-specific decisions. Discretion is necessary because not every legal situation can be anticipated in advance by the law, especially in dynamic and unpredictable situations that law enforcement professionals encounter daily. However, the exercise of discretion must be grounded in the core principles of justice, legal certainty, and respect for human rights, ensuring that decisions are made fairly and in accordance with legal norms. While discretion allows law enforcement officers to exercise judgment and adapt to diverse situations, it also carries significant risks, particularly the potential for abuse of power. Such abuse could manifest in inappropriate criminalization of innocent individuals, discriminatory practices, or biased decisions that undermine the legitimacy of the justice system. The possibility of such negative consequences necessitates a careful and responsible approach to the application of discretion. Law enforcement officers must not only act in accordance with the law but also adhere to ethical standards and ensure that their decisions are made transparently and equitably. Therefore, the study emphasizes the need for strict oversight and the development of clear, consistent guidelines to govern the exercise of discretion. Supervision mechanisms, such as internal audits and external oversight bodies, are crucial in monitoring law enforcement activities and ensuring that officers do not misuse their powers. Furthermore, providing adequate training to law enforcement personnel on the ethical and legal boundaries of discretion is vital in preventing arbitrary or unjust decisions.
