Abstract

Telah dilakukan percobaan menggunakan gelas ukur untuk menganalogikan peluruhan radioaktif yang mudah dipahami. Tujuan dari percobaan ini untuk menentukan waktu paruh dan konstanta peluruhan dari analogi radioaktif. Metode penelitian ini dilakukan dengan variasi tinggi dari masing-masing lubang pada gelas ukur dengan ketinggian 13 cm ; 22 cm ; 28 cm ; 31,5 cm dan 34,5 cm yang dilakukan pengulangan sebanyak 5 kali untuk setiap lubang. Dari hasil percobaan diperoleh waktu paruh (T) dari masing-masing lubang T1 = 0 s, T2 = 14,656 s, T3 = 17,532 s, T4 = 18,416 s, T5 = 21,798 s dengan konstanta peluruhan (λ) dari masing-masing lubang λ1 = 0 s-1, λ2 = 0,0472 s-1, λ3 = 0,0395 s-1, λ4 = 0,0376 s-1, λ5 = 0,0317 s-1. Berdasarkan hasil percobaan tersebut dapat disimpulkan bahwa hubungan antara waktu paruh dengan konstanta peluruhan berbanding terbalik karena semakin lama waktu paruh yang didapatkan maka semakin kecil nilai konstanta peluruhan.Kata Kunci: Waktu Paruh, Konstanta Peluruhan, Radioaktif

Abstract

Tujuan dari penelitian adalah untuk menentukan ketinggian dan kecepatan minimum benda pada track melingkar vertikal sehingga benda tidak terjatuh, seperti yang terjadi pada gerakan Roller Coaster. Penelitian ini menggunakan alat peraga sederhana yang dibuat semirip mungkin dengan track Roller Coaster untuk membuat simulasi gerak yang terjadi. Gerak benda yang terjadi dianalisis menggunakan software tracker, dan menggunakan perhitungan manual dengan menggunakan persamaan-persamaan yang berlaku pada gerak benda yang terjadi. Data yang diperoleh dari hasil perhitungan manual didapat bahwa agar benda dapat melintasi track tanpa terjatuh kecepatan minimal benda yang harus dicapai adalah 1,21 m/s dan ketinggian minimal benda yang harus dipenuhi menurut hasil perhitungan manual adalah 2,5 kali dari jari jari lintasan melingkar (2,5R). Untuk kasus ini karena jari-jari lintasan melingkar adalah 15 cm/0,15 m maka ketinggian minimal adalah 37,5 cm atau 0,375 m. Berdasarkan hasil percobaan menggunakan alat peraga, ketinggian benda agar tidak terjatuh dari lintasan adalah 50 cm dan analisis menggunakan software tracker didapat bahwa kecepatan benda ketika bergerak pada lintasan adalah 2,26 m/s juga hasil perhitungan manual kecepatan benda pada saat dilintasan adalah 2,31 m/s. Dari hasil kedua perhitungan tersebut dapat kita simpulkan bahwa persamaan-persamaan yang digunakan untuk mencari ketinggian dan kecepatan benda pada track melingkar vertikal sudah sesuai, karena kecepatan yang didapat dari hasil perhitungan mendukung hasil dari alat peraga. The purpose of this study is to determine the height and minimum speed of the object on the vertical circular track so that objects do not fall, as happened in the Roller Coaster movement. This study uses simple props made as closely as possible with the Roller Coaster track to make the simulation of motion taking place. The motion of objects that occur is analyzed using the tracker software and using manual calculations using equations that apply to the motion of objects that occur. The data obtained from the results of manual calculations found that for objects to cross the track without falling, the minimum speed of the object to be achieved is 1.21 m/s and the minimum height of the object according to the results of manual calculations is 2.5 times of the radius of circular trajectory (2.5R), for this case because the radius of the circular path is 15 cm / 0.15 m then the minimum height is 37.5 cm or 0.375 m. Based on experimental results using props, the height of the object in order not to fall from the track is 50 cm and analysis using the tracker software found that the velocity of objects when moving on the track is 2.26 m/s and also the result of manual calculation of the velocity of the object at that time is 2.31 m/s. From the result of both calculations can be concluded that the equations used to find the height and velocity of the object on the vertical circular track are appropriate, since the speed obtained from the calculation supports the results of props showing the object passing through the path without falling over the limit minimums that have been taken into account. Kata kunci: Gerak Melingkar, Roller coaster,Tracker, alat peraga

Abstract

In basic physics practicums there are some simplification of cases that aim to support the understanding of physics learning concepts. In practicum implementation there is a proof process that is carried out through an experiment and involves a formulation. This can be found in simple pendulum experiments, in which there are simplified cases that facilitate understanding of the factors that affect the pendulum period value. Therefore, this study aims to prove the value of the pendulum period based on experimental results and calculation data based on formulas. The experimental method used is to use simple pendulum props and observe the effect of pendulum mass, pendulum diameter, length of the rope, and angle deviation on the value of the pendulum period. The angle variations chosen were 15o, 30o and 45o. The results obtained show that at an angle of 15o, the magnitude of the period depends only on the value of the change in the length of the rope, while at an angle of 30o and 45o, the magnitude of the angle affects the value of the period. The pendulum mass and pendulum diameter do not affect the magnitude of the period for all angular variations. Period values obtained based on experimental results and formula calculations do not show significantly different values.

Abstract

The aim of this research is to develop Atwood machine propswith sensor-based PIR (Passive Infrared) to determine the acceleration value of earth gravity. This type of research is an experiment conducted in the physics laboratory of Universitas Indraprasta PGRI. Atwood machine was developed by using PIR (Passive Infrared) sensors to detect the movement of the objects used. Based on the trialof the result of the data analysis experiment tool, the acceleration of gravity was obtained (9.87 ± 0.08) m/s2. Whereas the value of acceleration of gravity in the literature is 9,80665 m/s2. The obtained results shows that the acceleration of gravity obtained in this research is not much different from the acceleration value of gravity  found in the literature so that Atwood machine tool that is developed by using PIR sensor is recommended to be one alternative tool in determining the acceleration of earth gravity.
