Dalam hal ini solusi persamaan yang akan digunakan sebagai solusi adalah persamaan Schrodinger dari koordinat bola. Posisi elektron dalam atom tidak dapat ditentukan dengan pasti, tetapi kita dapat menentukan probabilitas dengan menggunakan fungsi radial atom deuterium. Tujuan dari penelitian ini adalah pendekatan ketidakpastian Hesenberg dalam menentukan momentum dan spektrum energi atom deuterium n=4. Jenis penelitian ini adalah penelitian non eksperimen berupa pengembangan teori yang ada. Hasil penelitian ini meliputi (1) data distribusi probabilitas, ekspektasi, ketidakpastian momentum, dan simulasi keluaran grafik ketidakpastian momentum atom deuterium tergantung pada bilangan kuantum utama dan azimuth-nya, (2) data distribusi spektrum energi n≤4. Semakin besar nilai bilangan kuantum utama dan azimuth-nya akan mengakibatkan peningkatan nilai ketidakpastian momentumnya dan mengakibatkan penurunan nilai ketidakpastian posisinya, sehingga semakin akurat pengukuran posisi akan menghasilkan pengukuran momentum yang lebih tidak akurat. Data yang diperoleh menunjukkan bahwa semakin besar tingkat energinya, maka energi atom Deutrium yang diperoleh akan semakin kecil. Ini karena semakin banyak lintasan kulit atom akan menghasilkan lebih sedikit energi.","PeriodicalId":33966,"journal":{"name":"Gravity Jurnal Ilmiah Penelitian dan Pembelajaran Fisika","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136343956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pendekatan studi kasus digunakan untuk mengeksplorasi pengalaman dan pandangan mahasiswa yang terlibat dalam PLPP. Melalui wawancara mendalam dan analisis konten, penelitian ini mengungkapkan kompleksitas faktor-faktor yang membentuk tingkat kesiapan mereka dan bagaimana hal tersebut memengaruhi praktik pengajaran. Temuan menyoroti pentingnya pembekalan yang komprehensif dalam aspek kesiapan sebelum terjun ke lapangan. Implikasi dari penelitian ini adalah perlunya pendekatan yang holistik dalam mempersiapkan mahasiswa PPL Pendidikan Fisika, memastikan bahwa mereka memiliki keterampilan dan kesiapan emosional yang cukup untuk menghadapi tantangan dunia nyata dalam mengajar. Berdasarkan hasil penelitian dapat diketahui bahwa, terdapat beberapa kekurangan mahasiswa dalam hal kesiapan diri sebelum mengajar yaitu pemahaman konsep yang kurang mendalam, kurangnya persiapan materi, tidak siap secara emosional, kurangnya pengalaman praktik mengajar, kurangnya pengetahuan tentang strategi pengajaran, dan kurangnya keterampilan interpersonal mahasiswa.

The DRL value is obtained from the Volumetric Computed Tomography Dose Index (CTDIvol) which is obtained from a phantom with a diameter of 16 cm or 32 cm, so it is not yet possible to accurately estimate the dose for each patient, especially pediatric patients. The American Association of Physicists in Medicine (AAPM) then issued a water equivalent diameter (Dw) parameter to calibrate the CTDIvol to obtain a Size-Specific Dose Estimate (SSDE) so that it is more specific and effective. This study aims to obtain local DRL values and compare local DRL values in two pediatric age groups. This study used data from 25 pediatric abdominal CT scan patients aged <15 years, divided into two groups, ages 0-4 years and ages 5-15 years. The results of this study showed that typical DRLCTDIvol values for ages 0-4 years and 5-15 years were 3.09 mGy and 4.39 mGy respectively, while DRLSSDE for the two age groups were 3.25 mGy and 3.54 mGy respectively. There is a difference of 5.27% and 19.36% respectively from the local DRL value based on CTDIvol and SSDE for the two age groups. It can be seen that in the 0-4 year age group, the DRLSSDE value is greater than the DRLCTDIvol, conversely in the 5-15 year age group the DRLSSDE value is lower than the DRLCTDIvol which indicates that the dimensional factor affects the dose received by the patient.","PeriodicalId":33966,"journal":{"name":"Gravity Jurnal Ilmiah Penelitian dan Pembelajaran Fisika","volume":"44 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83247170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One important factor for plant growth is the need for sufficient light to support the process of photosynthesis. Efforts to overcome the lack of light is to use artificial light that comes from LED lights. This study aims to determine the effect of ultraviolet LED growth lamp power on the growth of lettuce plants. This study was divided into two groups: the control group without irradiating LED growth lamps and the experimental group using irradiation of LED growth lamps with a duration of irradiation of 4 hours at night. Parameters observed included plant height, leaf length, leaf width, number of leaves and leaf color in the third week. Analysis of research data used a non-parametric statistical test, namely the Kruskal Wallis test with the help of SPSS 23. The results showed that the power treatment of LED growth lamps had a significant effect on plant height, leaf length, leaf width and number of leaves. However, the power treatment of LED growth lamps did not significantly affect leaf color. The results showed that the best treatment was obtained at 18 watts of power.","PeriodicalId":33966,"journal":{"name":"Gravity Jurnal Ilmiah Penelitian dan Pembelajaran Fisika","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76742025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
