Abstract

Review of experimental effect of variations in the diameter of the nozzle and the amount of bucket on thepower and the efficiency on prototype pelton turbine in the Lab. Fluid. The aim of this study wants to know the effectof variations in the diameter of the nozzle and amount of the bucket to the power and efficiency of the existing peltonturbine prototype in the laboratory Fluid in the Pico-hydro scale. The steps in this research include the study ofliterature and field studies, designing, manufacturing of test equipment, testing, data analysis, and conclusions.Variation is done using nozzle diameter (dn) 6 mm and 9 mm, β2 at 165o, amount of bucket (Z) 12 units, 17 units,and 22 units. For the runner has a large diameter of 150 mm, while for the power plants or generators using spooland magnet on motorcycles. Results of this testing is the largest input power (Pin) at d 6 mm with a value of 46.81watts. The largest turbine power (Pt) and turbine efficiency (ηt) at dnn = 6 mm with Z = 12 unit with value P= 40,34watt and ηt =86,18 watt. The largest generator power (Pgen) at d = 6 mm with Z = 22 unit with value 9,6 watt,meanwhile for the largest generator efficiency (ηgenn) and the largest efficiency system (ηsis) at d= 9 mm with Z = 22unit with value ηgen = 54,24 % and η= 25,82 %.Keywords: Pelton Turbine, Bucket, Nozzle, Power and Efficiency

Abstract

Basic considerations of the Constitutional Court made ultra petita verdict  was:(a)  philosophical reasons in order to enforce substantive justice and constitutional justice as embodied in the Constitution NRI 1945, (b) theoretical grounds related to the authority of the judge to explore, discover and follow the legal values that live  in the community, if the law does not exist or insufficient legal anymore (outdated), and (c) juridical reasons relating to the provision of Article 24 paragraph (1) NRI 1945 Constitution and Article 45 paragraph (1) of Law no. 24 year 2003 on the Constitutional Court, that Court as organizers aim to enforce the judicial justice according to law and the evidence and the judge's conviction. The verdict the Constitutional Court which is ultra petita  basically acceptable, all associated  to  the subject of the request and based on considerations which can be accounted for philosophical (ie, contains the values of justice, morality, ethics, religion, principle, doctrine). The authority to make ultra petita verdict for the Constitutional Court can only be given if there is vagueness of legal norms (vague normen) through the method of interpretation of the law, or if a legal vacuum (rechts-vacuum) through the creation of legal methods (rechtschepping). But considering the legal interpretation and legal formation are highly subjective, hence in order to prevent abuse of power, the Constitutional Court issued a verdict ultra petita, should be limited by the principles of a democratic state of law,  the principles of fair trial and impartial, and general principles of good governance.

Abstract

Stroke remains a leading cause of disability and death, particularly in village areas where access to health education and preventive services is limited. While physical activity is known to reduce stroke risk, structured, community-based prevention programs are rarely implemented or studied in village settings. This study evaluates the implementation of anti-stroke exercises for stroke prevention in a village in Magelang, Central Java. A qualitative descriptive approach was used. Data were collected through focus group discussions and semi-structured interviews with village residents, community health workers, and local leaders in three village villages where the anti-stroke exercise program had been introduced. Thematic analysis was used to interpret the data. Participants reported increased awareness of stroke risk factors and the importance of physical activity. The exercise sessions were generally well-received and promoted social interaction among participants. Three key points for implementing anti-stroke exercises in rural areas aimed at preventing stroke were identified: early detection, education, and community participation. The program contributed to stroke prevention efforts by raising awareness and encouraging healthier lifestyles in village communities. Community engagement and leadership played crucial roles in the success of implementation. To strengthen the program, ongoing facilitator training, integration into broader public health strategies, and government support are needed. Regular monitoring and community feedback can help sustain and scale the initiative effectively.

Penelitian ini bertujuan untuk mengetahui apakah seks edukasi dengan media video evektif terhadap peningkatan pengetahuan seks dan sikap remaja tentang penyebaran konten pornografi di SMP N 6 Rembang. Metode penelitian ini menggunakan metode pre eksperimental, rancangan penelitian menggunakan One Group Pre-tes Post-test Design. Teknik pengambilan smapel dengan Simple Random Sampling dengan sampel sebanyak 72 responden. Variabel yang digunakan dalam penelitian ini adalah tingkat pengetahuan dan sikap sebagai variabel dependent dan seks edukasi dengan media video sebagai variabel independent. Teknik analisa data yang digunakan dengan Uji Wilcoxon dengan t-test sebagai alternative. Hasil penelitian menunjukan bahwa seks edukasi efektif terhadap peningkatan pengetahuan seks dan sikap remaja terhadap penyebaran konten pornografi di SMP N 6 Rembang dengan hasil untuk tingkat pengetahuan sebesar p=0,000 (p<0,05) dan untuk nilai sikap p=0,000 (p<0,05), maka Ha diterima.
