Korosi yang biasa disebut sebagai pengkaratan akibat terjadinya penurunan kualiatas mutu logam karena reaksi kimia suatu logam terhadap lingkungan disekitarnya. Banyak cara yang bisa dilakukan untuk memperlambat suatu laju reaksi pada korosi, seperti membuat paduan logam yang berfungsi agar tidak terjadi korosi, melapisi bagian logam agar tahan dari medium korosif, atau dengan cara membuat penambahan suatu zat yang berfungsi sebagai inhibitor penghambat korosi. Dalam penelitian ini dilakukan studi laju korosi dengan cara membuat penambahan zat yang berfungsi sebagai inhibitor dengan metode yang digunakan untuk mempelajari studi laju reaksi korosi adalah metode Gravimetri. Studi laju korosi ini bertujuan untuk mempelajari pengaruh inhibitor yang digunakan untuk penghambat korosi pada Aluminium. Data yang dihasilkan adalah menghitung massa benda uji sebelum dan setelah perendaman untuk dibandingkan. Hasil penelitian menunjukkan bahwa efisiensi inhibisi menghambat laju reaksi korosi Alumunium dalam larutan HCl berfungsi dengan nilai daya inhibisi 50 ppm inhibitor didapatkan pada waktu 5 menit 80.00%, 10 menit 77.06%, 15 menit 71.03%, 20 menit 62.17%, dan 25 menit 57.53% dengan laju korosi pada waktu 5 menit 0.0004, pada waktu 10 menit 0.0025, pada waktu 15 menit 0.0076, pada waktu 20 menit 0.01415 dan pada waktu 25 menit 0.02988.

Diabetes Mellitus is an autoimmune disease characterized by hyperglycemia secondary toreduced pancreatic insulin production, reduced insulin release in response to a carbohydrate load, ordisruption cellular response to insulin. The aim of this study to know the correlation between diet patternand lifestyle on diabetes melitus risk at Public Health Centre Pembina Palembang in 2016. This study useda survey design analytic through cross sectional approach. The population of this study were all patientswho come for treatment at Publich Health Centre Pembina Palembang in 2016, the total sample of thisstudy was 60 respondents. The result of analysis found that there are relationship of diet pattern ondiabetes melitus risk at public health centre Pembina Palembang in 2016 (ρ value = 0.013). There isrelationship of lifestyle on diabetes melitus risk at Public Health Centre Pembina Palembang in 2016 (ρvalue = 0.032). It is suggested to health officer should provide councelling and blood sugar level treatmentregularly, especially health centers, to prevent rising numbers of diabetes mellitus, especially in PublicHealth Centre Pembina Palembang

Diet is the most important behavior that can influence nutritional conditions. This can happen because the health level of a person and society can be influenced by the food and drink consumed based on its quality and quantity. Eating patterns that can cause hypertension are unhealthy foods such as snack habits, snack habits, instant food and fast food or foods that contain potassium. Foods that contain excessive fat can pose a risk of hypertension because they increase cholesterol levels in the blood. This study aims to determine the relationship between diet and the risk of hypertension among students, especially biology students at Ocean University. This research uses quantitative descriptive methods, using a quantitative approach using analytical observational research. The data analysis technique used in this research is two analyses, namely univariate analysis and bivariate analysis. The results of this study showed that there were 10 people with a percentage of 31.25% who were detected as normal (not at risk of developing hypertension) and there were 22 people with a percentage of 68.75% who were detected as having a risk of developing hypertension. This study also shows that there is a relationship between diet and the risk of hypertension with the value ∑X2 table (3.48)> ∑X2 calculated (2.6). So you need to pay attention to your diet to avoid the risk of hypertension.

This study aims to explore the influence of the physical learning environment on student learning behavior at SDN Parakanmuncang II. Employing a quantitative approach with an observational research design, data were collected from 200 students ranging from grades 1 to 6 through direct observation and questionnaire completion. The results of data analysis indicate that the physical learning environment at the school significantly impacts student learning behavior. The research findings reveal that comfortable, clean classrooms equipped with adequate learning facilities contribute positively to students' learning motivation. Sufficient lighting and comfortable room temperature also play a role in enhancing student concentration during learning. The cleanliness of the learning environment also affects student participation in classroom activities. However, there are several aspects of the physical learning environment that need further attention, such as improving lighting and classroom cleanliness. In the context of educational policy development, the research findings provide a strong foundation for increasing attention to the physical learning environment in school planning and management. Thus, this study makes a significant contribution to enriching our understanding of the importance of the physical learning environment in shaping student learning behavior and underscores the need for investment in improving physical facilities in schools to create a more conducive and supportive learning environment for students.
