Abstract

Bolus is a material that has properties similar to body tissues and is used to maximize the absorbed dose on the skin surface. The purpose of this research was to determine the most optimal treatment to kill fibrosarcoma on the patient’s skin surface by comparing the isodose curve and the value of the radiation absorption dose on the physical bolus (from CT-Scan) and model bolus (TPS). This study used data in the form of bolus images (with a bolus thickness of 0 cm, 0.5 cm and 1.0 cm) and phantom image. Then the data was processed with Treatment Planning System (TPS) and given energy variations in the form of electrons (10 MeV, 12 MeV, dan 15 MeV) and photons (6 MV and 10 MV). The result of this research was an isodosis curve that describes the distribution of the dose and the value of the absorbed dose of radiation received by the skin surface. The conclusion of this research is a bolus thickness of 0,5 cm and an electron energy of 15 MeV, has more even isodose curve (covering the entire tumor) and the maximum absorption dose value were 5720 cGy for physical bolus and 5710 cGy for TPS bolus.

Abstract

Banana kick is a type of soccer kick that uses the Magnus effect. The Magnus effect is a change in the direction of the ball's trajectory caused by the Magnus force. The force arises when a ball moving in air rotates on its axis. This research was conducted to analyze the ball entering the goal as a result of the Magnus force created by footballers. By means of Tracking Video Analysis and Modeling Tool software to several video tracks of football matches, it can be obtained the initial velocity, elevation angle, and angular velocity to determine the reach and heigh of the ball and the pertain Magnus force. The results of this study can be used in banana kick training.

Abstract

Saat ini pandemi Covid-19 telah menjadi faktor yang sangat berpengaruh dalam melakukan penelitian. Oleh sebab itu, umumnya penelitian yang dilakukan menyesuaikan kondisi sekarang dengan memanfaatkan alat dan bahan yang mudah diperoleh dan bisa dikerjakan dari rumah atau secara virtual. Pada penelitian ini dilakukan eksperimen elastisitas bahan berdasarkan prinsip Cantilever Beam yang bisa dilakukan di rumah. Preparasi sampel dilakukan dengan memotong kertas dengan variasi bentuk geometri dan densitasnya. Adapun geometri yang dipilih adalah persegi panjang dan trapesium. Persegi panjang divariasi densitasnya dengan variasi kertas polos, melapisi pilox sepanjang sampel dan juga pilox berselingan.Sementara yang berbentuk trapesium ditentukan dengan variasi polos dan dipilox sepanjang sampel. Eksperimen sederhana dilakukan dengan melakukan pemotretan pada sampel dengan sudut kelengkungan 00 , 450 dan 900 . Hasil pemotretan diolah dengan menggunakan aplikasi Video Tracker Analysis, Visual Basic Application dan fitting polynomial dengan Excel. Hasil yang diperoleh menunjukkan nilai modulus young setiap sampel tanpa harus melakukan pengukuran langsung dengan alat yang canggih serta bisa dilakukan di rumah selama pandemi Covid-19. Eksperimen ini berpotensi untuk dikembangkan lebih lanjut sehingga dapat menghasilkan metode baru dalam pengukuran elastisitas bahan.

Abstract

Cervical cancer is cancer that grows in the cells on the cervix. Cervical cancer can be treated using radiotherapy. The purpose of this study was to determine the ratio of the dose received by the target volume and Organ at Risk (OAR) as well as the isodose curve using 4 directions of radiation field (gantry angle: 0°, 90°, 180° and 270°) and 2 directions of radiation field (gantry angle: 0° and 180°). The data processing step in this research was to do radiation planning (planning) by using 4 directions of radiation field (gantry angle: 0°, 90°, 180° and 270°) and 2 directions of radiation field (gantry angle: 0° and 180°). Then a comparative analysis of the dose value received by the target volume and Organ at Risk (OAR) was carried out. A comparative analysis of the isodose curve was performed by using each of the techniques. The results obtained from this study are the target volume has minimal dose using the box technique compared to the antero posterior-postero anterior technique. For Organ at Risk, namely bladder and rectum, the dose was minimal by using the box technique compared to using the anteroposteriorpostero anterior technique. Meanwhile, the right and left femoral heads received higher doses using the box technique than the antero-posterior-postero anterior technique. And for the isodose curve planning results using the box technique shows a more even distribution of the dose distribution to the entire target volume compared to the antero posterior-postero anterior technique.

Abstract

Visualization of crystal structure and simulation of X-ray diffraction patterns of TiO2 (Titanium dioxide) was successfully performed by VESTA application. The purpose of this research is to obtain the relation of lattice parameter and composition to the diffraction pattern. The program on VESTA needs several input parameters that can be found on Crystallography Open Database (COD). The obtained output of the VESTA application are in the form of crystal structure and diffraction pattern graph. The data obtained by VESTA can be used to estimate the size of the crystal. The result showed that TiO2 has a tetragonal shape crystal structure. The addition of dopant such as Vanadium does not change the crystal structure and does not change the peak position of diffraction pattern graph.
