Abstract

This simple experiment with title  the analysis of the effect of cross-sectional area on air flow velocity using a venturimeter tube with aim to know the relation between section wide, speed of water flow and water level in capillary pipes and to know basic principle of Bernoulli and the application in simple set. The activity was reading water level of capillary pipes the caused by changes of water flow that started from heavy, medium, and low. Then analyzed the data that got for every changes of water flow that started from count the different water level in capillary pipes on big pipes and small pipes after that looking for speed of fluid flow on both pipes. Based on analyze data as a result relation between section wide, speed of water flow and water level in capillary pipes that was as bigger of section wide then the speed of water flow was getting smaller and the level water in capillary pipes was getting taller. This is appropriate with Bernoulli principle that states an increase in the speed of a fluid on a pipe with decrease in pressure and in reverse.Keywords: Venturimeter Tube, Cross-Sectional Area, Speed Of Water Flow, Water Level, Principle Of BernoulliEksperimen sederhana ini berjudul analisis pengaruh luas penampang terhadap kecepatan aliran air dengan menggunakan Tabung Venturimeter yang bertujuan untuk mengetahui hubungan antara luas penampang, Kecepatan aliran air dan ketinggian air pada pipa kapiler serta untuk mengetahui prinsip dasar hukum Bernoulli dan penerapannya dalam rangkaian sederhana. Kegiatan yang dilakukan adalah membaca ketinggian air pipa kapiler yang disebabkan dari perubahan laju aliran air dimulai dari deras, sedang dan rendah. Kemudian menganalisis data yang diperoleh untuk setiap perubahan laju aliran air yang dimulai dari menghitung perbedaan ketinggian air pipa kapiler pada pipa besar dan pipa kecil setelah itu mencari kecepatan aliran fluida pada kedua pipa. Berdasarkan analisis data diperoleh hubungan antara luas penampang, kecepatan aliran air dan ketinggian air pada pipa kapiler yakni semakin besar luas penampang pipa maka kecepatan aliran air pada pipa semakin kecil dan ketinggian air pada pipa kapiler semakin tinggi. Hal ini sesuai dengan bunyi asas Bernoulli yang menyatakan bahwa semakin besar kecepatan fluida dalam suatu pipa maka tekanannya makin kecil dan sebaliknya makin kecil kecepatan fluida dalam suatu pipa maka semakin besar tekanannya.Kata kunci: Tabung Venturimeter, Luas Penampang, Kecepatan aliran air, Ketinggian air, hukum Bernoulli

Abstract

Tidaran 1 Hamlet, Candiretno Village, Magelang Regency, is a rural area with quite heavy traffic in several areas. One location of particular concern is the bends and T-junctions in RT 11, which are frequently used by both two-wheeled and four-wheeled vehicles. This area is known to be an accident-prone area due to blind spots that obstruct the view of drivers from both directions. Unfortunately, to date, there are no safety facilities such as traffic signs or convex mirrors to aid visibility. Seeing this problem, students participating in the Community Service Program (KKN) from Tidar University conducted an intervention based on community needs. One effort was the installation of convex mirrors to minimize the risk of accidents. This activity was carried out using an action research method (action research), which included field observation, risk analysis, solution design, implementation, and impact evaluation. Throughout the process, students actively involved the community, the RT head, and village officials to ensure the proposed solution was participatory and sustainable. Convex mirrors with a diameter of 80 cm and a 2.5-meter-high support pole were installed at strategic points on the bends. Following the installation, follow-up observations and interviews with local residents were conducted. The results showed a significant improvement in visibility for drivers, especially at night and in similar weather. Residents reported feeling safer, less hesitant when crossing, and more alert to oncoming traffic. This program not only improved safety but also raised public awareness of the importance of traffic management. Therefore, similar interventions can be replicated in other vulnerable areas, with collaborative support from the community, universities, and village government.
