Abstract

ABSTRAK Silinder pejal yang menggelinding di atas bidang miring akan mengalami dua gerak sekaligus, yakni gerak rotasi dan translasi. Gerak rotasi terhadap sumbu silinder pejal dan gerak translasi terhadap bidang miring yang dilalui. Dinamika gerak rotasi dan translasi pada bidang miring menjadi kompleks saat silinder pejal bergerak 2 medium yang berbeda kerapatannya. Penelitian ini merupakan eksperimen di laboratorium untuk menentukan profil jarak terhadap waktu dan kecepatan terhadap waktu untuk gerak silinder pada bidang miring dalam air dengan variasi ketinggian air. Pengambilan data dilakukan menggunakan perekaman video dengan variasi ketinggian air pada saat silinder pejal menggelinding pada bidang miring, lalu video tersebut dipindahkan ke laptop untuk di-tracking menggunakan software tracker. Data yang diperoleh dari hasil tracking tersebut kemudian dibuat grafik profil jarak terhadap waktu dan profil kecepatan terhadap waktu. Pada hasil analisis data selain menghasilkan profil jarak terhadap waktu dan kecepatan terhadap waktu juga memperoleh pengaruh variasi ketinggian air pada profil jarak terhadap waktu dan kecepatan terhadap waktu. Semakin tinggi air, maka semakin pendek lintasan yang ditempuh oleh silinder. Perubahan kecepatan silinder cenderung tidak linear bila ketinggian air tidak tinggi karena gaya gesekan dengan lintasan mulai membesar. Silinder bergerak dengan kecepatan hampir konstan pada saat di dalam air. Kata  kunci— Silinder pejal, software tracker, bidang miring, air ABSTRACT A solid cylinder that rolls on an inclined plane will experience two motions at once, namely rotational and translational motion. Rotational motion about the axis of a solid cylinder and translational motion about the inclined plane traversed. Rotational and translational motion dynamics on inclined plane become complex as a solid cylinder move inside two different mediums that has different density. This research is an experimental research in the laboratory to determine the profile of distance and velocity versus time of cylinder on an inclined plane in water with variations in water level. Data retrieval is done using video recording with variations in water level when a solid cylinder rolls on an inclined plane, then the video is transferred to a laptop for tracking using tracker software. The data are plotted to obtain graph of distance and velocity profile In the results of data analysis, in addition to producing a profile of distance against time and speed with respect to time, it also obtained the effect of variations in water level on the profile of distance against time and speed with respect to time. Higher the water height, shorter the cylinder path. The changes of cylinder speed tend to be non-linear if the height of water is low. This is due to the drag force with the track start to increase. Cylinder move with the speed almost constant under water. Keywords— Solid cylinder, tracker software, inclined plane, water

Abstract

Parabolic motion is the typical phenomenon in classical mechanics. The students are able to understand the concept by reading the data in the parabolic function. However, there is limited material for visual impaired students to study the parabolic motion data. One of the solutions to overcome this problem is the parabolic motion experiment development using sonification method. Research has been carried out to analyze the accuracy of the frequency produced by the speakers in data conversion assisted by Arduino Uno. The research also analyzes the effect of elevation angle variations on the resulting frequency changes. The data collection process is carried out by analyzing the percentage of accuracy using the average technique of the data recorded by the Phyphox application. The data analysis of the Phyphox application is compared with the data obtained from the Tracker application. From the results of data analysis obtained the percentage value of the velocity for the angle 30o, 45o, and 70o were 99.92%, 99.67%, and 98.42%, respectively. Therefore, it can be said that the preliminary sonification study is feasible to be used in physics experiments on parabolic motion learning, especially for visual impaired students. The final plotting result of this research shows that the frequency versus time at each angle produces a graph in the parabolic form. While the effect of angle variations on frequency changes is that the larger the angle, the slower it will reach the peak frequency.

Abstract

This study aimed to determine the volume of traditional eucalyptus oil from distillation with variations in fluid flow velocity. The method of distillation was distillation with water (water distillation). The material was eucalyptus leaves. To determine the volume of eucalyptus oil produced by distillation, the distillation device was set at the height of the condenser to the source of flow fluid, which was at an altitude of 15 cm, 25 cm, 35 cm, 45 cm, and 55 cm. Variation in the height of the condenser would affect the fluid flow rate. The faster the fluid flow rate, the greater the convection coefficient so that it increased the heat transfer rate. This results in greater volume (capacity) of oil produced. From these experimental results, most volumes of eucalyptus oil obtained from the distillation was obtained at 55 cm of the height of condenser with 3.6 mLof oil volume.

Abstract

Astronomical observatories can be declared feasible if they have a good condition such as a dark sky, relatively little cloud coverage, relatively low light pollution, and small air turbulence or seeing. The UAD (Universitas Ahmad Dahlan) observatory was measuring the seeing characteristic to assess the feasibility condition. The DIMM method (Differential Image Motion Monitor) was utilized to get the measurement in April, May, and September 2019. The 150 mm diameter Celestron C6-N telescope was used as the instrument to get the star images. The characteristics of a good seeing value on April 10, 2019, are Procyon star with a value of 0.2 arc seconds, and on September 18, 2019, the Vega star with a value of 1.6 arc seconds. Analysis of the seeing characteristic at the UAD Observatory can be used as a reference for observers on star selection, and the operation of the telescope
