Abstract

Vortex turbine is the one of turbines which meets those criteria. This turbine utilizes kinetic energy of vortex water and converts it into a shaft power. The objectives of this research were to obtain the torque that could be generated from the vortex  turbine by varying the width of turbine blades and to know  the output  power also the optimum efficiency obtained from this variation. This research was conducted by  using vortex pool in a laboratory scale with a diameter of 108 cm and 6 turbine blades on permanent rotation at 50 rpm, 60 rpm, and 70 rpm. Turbine blades were made from flat rectangular steel with a length of 40 cm sized 1/6, 2/6, 3/6, 4/6 and 5/6 times to radius of vortex pool.The results of the research showed the torque as 1.40 Nm at rotation is 50 rpm. The maximum power is obtained from blade with width of 3/6 times  radius of the pool, that is  8.60 Watts at head 0.362 m and discharge 11.83  l/s or  0.01183 m3/s at rotaion shaft is 70 rpm. This experiment also generated and turbine efficiency of 16.46% at rotation of shaft is 70 rpm.

Abstract

Anggar adalah olahraga pertarungan dengan 3 jenis pedang yang digunakan. Floret/foil, sabre, dan degen/epee adalah pedang yang digunakan dalam olahraga ini. Dasar permainan anggar adalah gerakan kaki yang disebut dengan footwork. Salah satu gerakan footwork adalah lunge. Lunge menggunakan otot rectus femoris sebagai penggerak utama. Hal ini akan berpengaruh pada kualitas lunge jika atlet mengalami cidera lutut. Penelitian ini bertujuan untuk menganalisis aktivitas otot rectus femoris saat melakukan gerakan lunge pada atlet anggar nomor sabre yang memiliki riwayat cedera lutut. Penelitian kuantitatif dengan metode observasional analitik dan pendekatan cross-sectional. Sampel adalah 3 atlet anggar nomor sabre dan floret, berusia 15-24 tahun dengan riwayat cedera lutut. Aktivasi otot rectus femoris diukur oleh S-EMG saat gerakan lunge. Hasil S-EMG nilai kontraksi otot rectus femoris pada ketiga subjek sabre adalah sekitar 48.33 mV, 53.33 mV dan 52 mv. Sementara floret sekitar 96,67 mV, 91,33mV dan 96 mV. Hasil perekaman data S-EMG menunjukkan bahwa terdapat hubungan antara aktivitas listrik otot rectus femoris pada atlet anggar nomor sabre yang pernah mengalami cidera, sedangkan pada nomor floret cidera tidak mempengaruhi aktivasi otot rectus femoris.

Abstract

Introduction : This case report shows the application of the exercise therapy method with the New Bobath Concept Approach in cases of Traumatic Intracerebral Hemorrhage (TICH) and reports the results of the exercise. Case presentation: Mr. AR, a 16-year-old student with a clinical diagnosis of Traumatic Intracerebral Hemorrhage (TICH) received an exercise therapy program with a New Bobath Concept Approach consisting of abdominal exercise, facilitate foreward & backward pelvic, bridging exercise, sensibility exercise, sitting and sitting balance exercise, mobilization and facilitation of the scapula and arm, core stability exercise, standing exercise, facilitation of walking patterns and walking exercise. Management and outcome: Exercise was carried out for 12 weeks with a frequency of twice a week and a duration of 60 minutes per training session. Discussion: After giving exercise therapy with the New Bobath Concept Approach for 12 weeks, the results showed an increase MMT value in muscles shoulder, elbow, wrist, fingers, hip and knee from 0 to 2 and 3. Meanwhile for the Barthel index from a value of 2 (total dependence) to 10 (moderate dependence). Conclusion: Mr. AR is able to sit, stand independently and walk 100 meters with assistance.

Abstract

Carpal Tunnel Syndrome (CTS) merupakan salah satu gangguan saraf perifer yang umum terjadi, terutama pada individu dengan aktivitas berulang yang melibatkan pergelangan tangan. Edukasi mengenai pencegahan dan penanganan CTS sangat penting untuk meningkatkan pemahaman komunitas berisiko, seperti kelompok ibu-ibu penggiat rebana yang sering menggunakan tangan dalam aktivitas musik. Pengabdian ini bertujuan untuk memberikan edukasi tentang CTS melalui metode ceramah dengan media leaflet dan demonstrasi. Materi edukasi mencakup pengenalan CTS, faktor risiko, gejala, pencegahan, dan teknik latihan rehabilitasi. Demonstrasi praktis meliputi Phalen Test dan Tinnel Test untuk mendeteksi CTS, serta nerve gliding exercise untuk mengurangi gejala dan meningkatkan fungsi saraf. Metode ini diterapkan pada komunitas ibu-ibu rebana di lingkungan tertentu, dengan pendekatan partisipatif untuk memastikan pemahaman dan keterlibatan peserta. Edukasi ini diharapkan dapat menjadi model intervensi kesehatan yang aplikatif dan relevan untuk kelompok komunitas serupa.

Abstract

The digitalization era significantly influences human life, such as lifestyle and physical activity. Human life change happens because of the ease of access provided by digitalization to purchase goods from home. This matter becomes the predictor of waist circumference and body mass index increase with obesity risks. Larger waist circumference influences the increased intra-abdominal fat accumulation. This fat accumulation leads to obesity and hypertension. This research aims to determine the correlation between waist circumference and blood pressure of people aged from 25 to 60 years old in Palur village, CA III. This cross-sectional research used chi square data analysis. The results showed that 51 people out of 100 had a larger waist circumference than 90cm suffering from hypertension.

Abstract

Suak Baru Village in Simeulue Regency, Aceh, faces challenges in waste management, particularly in the tourist area of Suak Baru Beach. This situation is exacerbated by the lack of adequate waste management facilities, leading to environmental pollution that threatens public health and the area's attractiveness to tourists. The design of this community service program aims to increase the community's preparedness for the adoption of environmentally friendly waste management technologies, specifically composting and plastic recycling methods. The activities include socialization, training, technology implementation, and program sustainability evaluation. The program's results show a significant improvement in the community’s understanding of effective waste management. The use of organic and plastic shredding technology successfully reduced waste volume and created economic value through recycled products. It is hoped that government support and active community participation will ensure the sustainability of this program for a cleaner, healthier environment and improved local economic welfare.
