Sistem rem tromol pada kendaraan menghasilkan panas yang cukup tinggi akibat gesekan antara kampas rem dan permukaan tromol, sehingga diperlukan metode pendinginan yang efektif untuk menjaga kinerja dan keamanan sistem pengereman. Salah satu metode yang dapat digunakan adalah pendinginan menggunakan udara bertekanan yang disemprotkan melalui nozzle dengan ukuran tertentu. Penelitian ini bertujuan untuk menganalisis pengaruh variasi ukuran nozzle terhadap efektivitas penurunan temperatur rem tromol. Metode yang digunakan dalam penelitian ini adalah dengan melakukan pemanasan terhadap backplate tromol menggunakan hot gun hingga mencapai temperatur 150°C. Setelah itu, dilakukan penyemprotan udara bertekanan melalui nozzle berukuran 1/4 inci, 1/2 inci, dan 3/4 inci, dengan tekanan udara konstan sebesar 5 bar dan dalam kondisi lingkungan tetap. Temperatur akhir setelah penyemprotan diukur untuk masing-masing ukuran nozzle pada durasi waktu10 detik. Hasil pengujian menunjukkan bahwa nozzle berukuran besar (3/4 inci) mampu menurunkan temperatur tromol secara lebih signifikan dibandingkan ukuran lainnya. Semakin besar ukuran nozzle, semakin besar debit udara yang dihasilkan, sehingga proses perpindahan panas melalui konveksi menjadi lebih efektif. Dengan demikian, dapat disimpulkan bahwa ukuran nozzle merupakan salah satu faktor kunci dalam meningkatkan efisiensi pendinginan rem tromol menggunakan udara bertekanan.

Kecelakaan lalu lintas merupakan permasalahan serius yang terjadi secara global, termasuk di Indonesia. Salah satu faktor utama penyebab kecelakaan adalah kegagalan sistem pengereman, khususnya rem blong. Rem blong umumnya disebabkan oleh overheating pada sistem rem, yang mengakibatkan berkurangnya daya cengkeram rem atau munculnya vapor lock, sehingga pengemudi tidak dapat mengendalikan kendaraannya. Kondisi ini sangat berisiko, terutama pada kendaraan bermuatan berat seperti truk, bus, dan mobil pick-up. Panas berlebih pada sistem rem terjadi karena gesekan saat pengereman menghasilkan temperatur yang melampaui kapasitas sistem, sehingga mempercepat kerusakan dan meningkatkan potensi kecelakaan. Salah satu solusi untuk mengatasi hal ini adalah dengan menjaga temperatur rem tromol, yaitu melalui sistem pendingin otomatis menggunakan udara bertekanan yang diarahkan ke rem tromol. Metode ini  mencegah kegagalan sistem rem akibat panas berlebih dan meningkatkan keselamatan kendaraan berat. Penelitian ini dilakukan pada prototipe rem tromol untuk menguji efektivitas udara bertekanan (5 bar) dengan memvariasikan jarak nozzle (8 mm, 10 mm, dan 12 mm) dengan sudut nozzle (45°) secara otomatis menggunakan Arduino Mega 2560. Tujuan dari penelitian ini adalah untuk mendapatkan data yang akurat mengenai jarak yang paling berpengaruh dalam menurunkan temperatur rem. Hasil terbaik diperoleh pada jarak yang tedekat yaitu 8 mm, dengan temperatur pendinginan terendah sebesar 127,64°C.

Restless Legs Syndrome (RLS) is a common but often undiagnosed neurological disorder, characterized by an urge to move the legs accompanied by uncomfortable sensations, especially during rest at night. This condition is common in the elderly, disrupts sleep, and negatively impacts mood, energy, and quality of life, especially in nursing home residents. This study investigated the relationship between Restless Legs Syndrome (RLS) and quality of life in the elderly living in nursing homes. The research design was cross-sectional, with a consecutive sampling technique. The independent variable in this study was the severity of RLS measured using the IRLSSG questionnaire. Higher scores of IRLSSG and SF-36 indicated severe RLS and better QoL. Data analysis was conducted using the Spearman correlation test to assess the relationship between RLS and quality of life. The sample used in this study was 70 participants, calculated using G power software. The results showed that the average age of the participants was 75.41 years, with the majority of participants being women. Most participants experience mild RLS (67.14%). Statistical tests showed a significant negative association between RLS and QoL, specifically in the bodily pain (BP) domain, with a p-value of 0.04 and r= - 0.2465, which means increasing RLS will increase BP. Participants experienced mild pain, while 24.29% reported moderate pain, and 8.57% experienced severe pain. Statistical tests showed p value of 0.05, which indicates a significant relationship between the severity of RLS and quality of life. RLS has a significant impact on the quality of life in the elderly. Therefore, healthcare providers need to recognize and manage RLS symptoms to improve the overall well-being of this population. For further research, researchers need to consider additional factors such as comorbidities and social support, and implement interventions to reduce RLS symptoms.

Additionally, instructors should receive training to use these media innovatively and effectively, ultimately improving learning efficiency and helping students achieve optimal results.

Dengue Hemorrhagic Fever (DHF) is a disease caused by the dengue virus and transmitted by the Aedes aegypti mosquito. The working area of the Rawasari Health Center in Jambi City shows a trend of increasing dengue cases from year to year. This indicates that there may be other factors influencing the incidence of dengue, including physical environmental conditions and community behavior. The objective of this research is to determine the relationship between the presence of mosquito larvae in water reservoirs/containers, the action of hanging clothes, using mosquito repellent, cleaning water containers, disposing of waste items, and installing wire mesh with the incidence of dengue fever in the working area of the Rawasari Health Center in 2025. This research uses a quantitative study, with a case control design. The sample size consisted of 24 cases and 24 controls determined by matched case control study techniques based on age and gender. Data were collected through questionnaires and observation sheets, and analyzed using the chi-square test to determine the relationship between the independent variables and the incidence of dengue fever. The results show that the presence of mosquito larvae in water storage containers (p-value 0.042), practices of cleaning water storage containers (p-value 0.020), actions to eliminate waste items (p-value 0.043), and the installation of screens or mosquito nets (p-value 0.004) are significantly related to the incidence of dengue fever. Conversely, other factors such as the habit of drying clothes and the use of mosquito repellent did not show a statistically significant relationship with dengue fever cases in the study population. There is a significant relationship between the actions of cleaning water storage places and installing wire mesh. Effective prevention requires active community involvement in maintaining environmental cleanliness and consistently implementing the 3M Plus practices.

Bullying is a deviant behavior that can occur among students in the school environment. Bullying behavior will have a negative impact on its victims, both physically and psychologically. The impact on victims can be in the form of psychological disorders, loss of self-confidence, the tendency for students to be difficult to trust others (trust issues), and tend to be alone. Civic Education is present to create (civic disposition/responsibility) the character or attitude of the student's personality and be able to take responsibility. The role of Civics teachers in providing subject matter is very much needed so that students can form character values in behavior, both in the school environment so as to prevent deviations among students such as bullying. Pancasila and Citizenship Education teachers need to educate as well as teach, duly trying to prevent issues of bullying behavior. The objectives of this study are 1) to know the role of Civics Teachers in strengthening character to prevent bullying behavior at SMP Negeri 17 Medan 2) to know the negative impact of bullying behavior among students at SMP Negeri 17 Medan. This type of research is a type of narrative qualitative research. Data collection techniques in this study were interviews, observation and documentation. The sample in this study were all Civics Teachers at SMP Negeri 17 Medan, which were 2 Civics teachers. The results showed that Civics teachers at SMP Negeri 17 Medan have carried out the role of teachers as role models, inspirers, motivators, dynamizers and evaluators. It can be seen that the negative impact of bullying for victims can be in the form of physical and psychological injuries, not wanting to come to school, feeling inferior, losing a sense of security and comfort. Meanwhile, the perpetrators, if not caught or caught bullying, will repeat their actions continuously
 

Iron deficiency anemia (ADB) is anemia that arises due to reduced iron supply for erythropoiesis, due to empty iron stores (depleted iron stores) which ultimately results in reduced hemoglobin formation. This study aims to determine the effect of giving blood supplement tablets on HB levels in female students suffering from anemia at SMAN 1 Tambakboyo, Tuban Regency. The research design used a pre-experiment using a one group pre test post test approach, with a total sampling technique on a population of 34 female students suffering from anemia in class X and analyzed using the Wilcoxon test. The instruments in this research were Standard Operating Procedures (SOP), hemoglobin level observation sheets and Easy Touch GCU brand hemoglobin measuring equipment. The results of the study showed that the average HB level before 10.17 g/dl and after 15.46 g/dl given blood supplement tablets was normal. The results of the Wilcoxon test obtained a significant value of p=0.000 (p<0.05), which means that there was a significant difference in the HB levels of class X female students before and after being given blood supplement tablets. Health workers, especially in school health offices, should provide blood supplement tablets at the right time so that female students can take the blood supplement tablets regularly and finish them.
