Abstract

The presence of media in the learning process acts as a tool to prevent communication failures between teachers and students. This study aims to determine the effect of Annotated Illustration and PhET media on physics learning achievement on Dynamic Electricity material. The research method used in this study is a quantitative research method. While the type of research is experimental research. In this study, the PhET media was applied to the experimental class, while the Annotated Illustrations media was applied to the control class. The calculation results obtained = 3.836 and = 2.056 at a significant level of 5% and dk = 1 + 2. Therefore > , so that the null hypothesis (H0) is rejected or the alternative hypothesis (Ha) is accepted, which means that there is a difference in the effect of Annotated Illustrations and PhET on physics learning achievement on Dynamic Electricity material.

Abstract

This study aims to create a tool that can explain the event of the photoelectric effect on a laboratory scale. So that the existence of a tool that can explain the photoelectric effect will make it easier for users to study the nature of light as a particle. This tool is designed according to its function which will find out that the photoelectric effect event is not influenced by light intensity but is influenced by the frequency of a light source and the wavelength that illuminates a metal so that electrons will move from a negative source towards a positive voltage source. In the manufacture of these tools, a photodiode is used as a light sensor where when the photodiode is illuminated by light it will cause electrons to move from the cathode to the anode and make an electric current flow. To determine the stopping voltage, a voltage is applied to the cathode where the electrons are ejected. This stopping voltage for each wavelength is different. From the ongoing data retrieval, a graphic relationship is obtained between the ADC value and the Sensor Output Voltage. Thus, it can be concluded that, First, the voltage applied to the photodiode (cathode) is different for each color spectrum. Second, the output voltage obtained for each different wavelength, the less light intensity received by the photodiode, the smaller the output voltage value. The amount of output voltage for each LED color is different because the wavelength of each color is also different so the value is not the same.

Abstract

The impact of high-intensity noise can cause discomfort for crew and ship passengers. The noise is partly caused by the maine engine which is the biggest noise source. So it is necessary to find a solution on how to reduce noise and the impact of the noise. The purpose of this study was to determine the magnitude of the sound intensity and the effect of sound intensity on the comfort of the crew and passengers. The research was conducted using the Sound Level Meter (SLM) application. Measurements made in the passenger compartment and an average of 66.4 dB to 73.6 dB indicate that the ship's engine noise level when operating is included in the strong category according to Suma'mur's study, 2009, but does not cause deafness and hearing damage.

Abstract

Morals are very important, so Allah SWT sent his messenger to fix it. Morals, attitude and character positive are life skills. Life skills cannot be taught, they should be transmitted, so a model is needed to be imitated. Scientific phenomena have the potential to be a model. Nature saves a lot of messages from Allah SWT which, if digested, becomes knowledge. One of the scientific phenomena in nature that can be used as knowledge and improve life skills are butterflies and magnets. Literature study is used to analyze scientific phenomena from several aspects, namely 1) religion based on Al-Quran and Hadith, 2) scientific concepts of phenomena found in nature, 3) application in life, and 4) integration in life skills. Butterflies can be a model of the importance of self-control to be good and not give up quickly in the face of difficulties and the belief that with difficulties there is ease. Magnets become a model of unity, rhythm, agreement, strength will be achieved. Based on the analysis, it can be concluded that the creation of Allah SWT in nature in the form of scientific phenomena can be a model for improving life skills.

Abstract

The increase in the incidence of disasters in recent years has given birth to many ideas in disaster mitigation efforts to save lives from the effects of disasters. The disaster mitigation system in Indonesia is still far from ideal. Mitigation technology is only limited to pre-disaster and early warning. There is no technology that facilitates knowledge and preparedness. Education and disaster mitigation procedures that must be imitated by the community are very necessary. The aim of the study was to determine the effectiveness of the disaster mitigation learning model on disaster awareness of students at SD N 6 Mataram. This study was limited to 25 fifth grade or high grade students at SD N 6 Mataram using a one group pretest-posttest design. Disaster mitigation awareness is measured using an objective test instrument with 25 items. Disaster mitigation awareness includes disaster knowledge (PK), disaster signs (TB), risk impact and efforts to reduce (DR), preparedness (KN), and procedures, first aid tools for victims (AP). The disaster mitigation awareness test instrument used has been tested for validity and reliability. The data obtained were statistically analyzed using SPSS 23.0 by performing normality test and paired t-test (paired t-test). The results showed that the student-oriented disaster mitigation learning model was effective in increasing the disaster awareness of students at SD N 6 Mataram.

Abstract

Radioterapi kanker serviks pada pesawat Linac menggunakan berkas photon energi 6 MV dengan teknik 3 Dimension Conformal Radiotherapy (3DCRT) dan Intensity Modulation Radiation Therapy (IMRT). Perencanaan radioterapi pada tehnik 3DCRT dan IMRT  kemudian dibandingkan dengan menganalisis distribusi dosis atau planning target volume (PTV) coverage melalui Conformity Index (CI) dan Homogeneity Index (HI) serta Organ At Risk (OAR) dimana organ beresiko yang diperhatikan adalah rektum. Pada penelitian ini menggunakan 30 data pasien kanker servik di Instalasi Radioterapi RSUP Sanglah Denpasar dengan perencanaan menggunakan box system  pada teknik 3DCRT dan teknik IMRT dengan sudut rotasi 00, 900, 1800, dan 2700 dan dosis radiasi 5000 cGy. Perbandingan kedua teknik ini dilakukan dengan menganalisis kurva Dose Volume Histogram (DVH) pada PTV coverage yang terdapat pada komputer Treatment Planning System (TPS). Hasil penelitian ini menunjukan nilai rata-rata CI pada tehnik 3DCRT adalah 1,017542 sedangkan pada tehnik IMRT sebesar 1,019668, dengan uji mann whitney (Asymp.Sig =0,492). Demikian juga dengan nilai HI, dimana pada tehnik 3DCRT rata-ratanya adalah 0,089494 sedangkan pada tehnik IMRT sebesar 0,093126 denga uji mann whitney (Asymp.Sig = 0,487), kedua nilai CI dan HI tidak signifikan. Sedangkan persentase dosis rata-rata organ rektum pada kedua teknik penyinaran 3DCRT dan IMRT berturut-turut yaitu 96% dan 87% dengan hasil uji statistik diperoleh nilai Asimp.Sig = 0.000 yang berarti signifikan. Radioterapi kanker serviks dengan menggunakan teknik IMRT dapat meminimalisir dosis serap pada OAR (rektum).
