Abstract

Penelitian ini adalah penelitian Eksperimen Semu (Quasi Experimental) yang bertujuan untuk (1) memperoleh informasi tentang hasil belajar fisika peserta didik yang diajar menggunakan Metode pemberian Tugas terstruktur dan yang diajar secara konvensional. (2) mengetahui ada tidaknya perbedaan yang signifikan antara hasil belajar fisika peserta didik yang diajar menggunakan metode pemberian tugas terstruktur dan yang diajar secara konvensional. Desain penelitian adalah Nonequivalent Control Group  design yang melibatkan satu variabel bebas dan satu variabel terikat. Variabel bebasnya berupa: metode pembelajaran yang terdiri atas dua dimensi yaitu  pemberian tugas terstruktur dan secara konvensional. Variabel terikatnya adalah hasil belajar fisika.  Populasi penelitian adalah peserta didik kelas XI MIA SMA Negeri 22 Makassar tahun ajaran 2014/2015  dengan sampel penelitian peserta didik  kelas XI MIA 2 dan peserta didik kelas XI MIA 3. Kelas XI MIA 2 diberi perlakuan berupa pembelajaran menggunakan metode pemberian tugas terstruktur  dengan jumlah peserta didik 42 orang dan  kelas XI MIA 3  yang diajar secara konvensional dengan jumlah peserta didik 43 orang. Hasil analisis deskriptif mengungkapkan bahwa skor rata-rata hasil belajar fisika peserta didik kelas eksperimen adalah 17,40 dengan standar deviasi 3,21 dan skor rata-rata hasil belajar fisika peserta didik kelas kontrol adalah 16,35 dengan standar deviasi 3,03. Hasil analisis inferensial mengungkapkan bahwa terdapat perbedaan  yang signifikan hasil belajar fisika peserta didik kelas XI MIA SMA 22 Makassar antara yang diajar menggunakan  metode pemberian tugas terstruktur dan yang diajar secara konvensional pada taraf signifikasi Kata kunci: hasil belajar, pemberian tugas terstruktur, model pembelajaran konvensionalThis study was a quasi-experimental research ( Quasi- Experimental ) that aims to ( 1 ) obtain information about the physics learning outcomes of students who were taught using the method of administration tasks are structured and taught conventionally . ( 2 ) determine whether there is a significant difference between the results of studying physics students are taught using the method of administration tasks are structured and taught conventionally . The study design was a nonequivalent control group involving one independent variable and the dependent variable . The independent variables such as : learning method consists of two dimensions , namely the provision of structured and conventional tasks . The dependent variable is the result of learning physics . The study population is of class XI students of SMAN 22 Makassar MIA academic year 2014/2015 with a sample of students of class XI MIA 2 and students of class XI MIA 3 . Class XI MIA 2 treated form of learning using structured task giving the number of learners 42 people and 3 MIA XI classes taught conventionally the number of learners 43 people . Descriptive analysis revealed that the average score of students learning outcomes physics class experiment was 17.40 with a standard deviation of 3.21 and an average score of student learning outcomes physics control class is 16.35 with a standard deviation of 3.03 . The results of inferential analysis revealed that there were significant differences in learning outcomes of students of class XI physics MIA SMA 22 Makassar between the taught using the method of administration tasks are structured and conventionally taught at the level of significance.Key words: learning outcomes , structured method of administration tasks, taught conventionally

Abstract

A study has been conducted analyzing the Entrance Skin Dose (ESD) value on PMMA phantoms based on variations in Field of View (FOV) and thickness. In addition, the magnitude of the dose scattering that reaches the thyroid and gonad areas of radiation workers when C-Arm fluoroscopy examination is performed was also tested. The variation in phantom thickness values ​​was 15, 20, and 25 cm while the variation in FOV irradiation values ​​was 12, 15, 17, and 20 cm. The purpose of the study was to determine the magnitude of the change in ESD value due to changes in object thickness which will also directly affect changes in peak voltage for each irradiation. This also has implications for providing an increasing scattering dose due to the presence of the object. The results showed that the larger the FOV and thickness of the phantom, the higher the ESD value received. At a phantom thickness of 25 cm, ESD increased from 6.42 mGy at a FOV of 12 cm to 11.61 mGy at a FOV of 17 cm. The scatter dose value that reaches the thyroid area is a maximum of 22.31 µSv at FOV 20 cm, while the gonad area receives 1.647 µSv, which is lower because the fluoroscopy machine is equipped with Pb protection for radiation workers when performing interventions. The conclusion in C-arm fluoroscopy examinations, radiation workers must also use protective equipment for other vital areas such as Pb glasses and neck protection to be safer from scattered radiation.

Abstract

Performance evaluation of diagnostic radiology modalities strongly supports the quality of radiation and images for diagnosis. This test requires certain materials as a substitute for human objects to avoid excessive radiation. Phantom as one of the object replacement media has been directed according to the characteristics of the tissue. This study aims to obtain the radiation response of artificial bone tissue made from eggshells with the addition of rice bran, resin and catalyst, in 4 (four) mixture compositions. Test variations were carried out by changing the X-ray tube voltage (80 kV, 100 kV, 120 kV and 140 kV) to obtain CT-Scan images and analyzed using Radiant DICOM software. The results showed that the Hounsfield unit (HU) value of the artificial bone phantom corresponded to the HU value range of real bone organs, which is between 100 and 700 HU. This value affects the analysis of the resulting image resolution in the form of SNR and CNR values, in the range of (8.07-37.38) and (14.98-28.20), respectively. Conclusion Artificial bone tissue phantom made from eggshells and rice bran has the potential as a testing medium because it corresponds to the characteristics of human bones, especially in adulthood, and has the potential as a testing medium.

Abstract

Stunting, yang ditandai dengan tinggi badan di bawah standar usia, merupakan masalah nutrisi serius pada balita yang berpotensi mempengaruhi kesehatan dan perkembangan kognitif mereka. Penelitian ini dilakukan untuk mengeksplorasi faktor-faktor yang berhubungan dengan stunting pada anak usia 24-59 bulan. menggunakan desain survei analitik observasional. Dari populasi 83 balita, 45 diambil sebagai sampel melalui Probability Sampling, dengan perhitungan sampel menggunakan rumus Slovin. Data dikumpulkan via kuisioner dan dianalisis menggunakan SPSS versi 25 untuk analisis univariat dan bivariat dengan chi-square. Hasil menunjukkan hubungan signifikan antara pemberian ASI eksklusif, tingkat pendidikan orang tua, dan pendapatan keluarga terhadap kejadian stunting. Penelitian ini mengidentifikasi pentingnya ASI eksklusif, edukasi orang tua, dan kondisi ekonomi keluarga dalam mengatasi stunting di wilayah tersebut
