Judul: Factors Related to the Inciden of Overweight in High School Adolescents in Magetan during the Pandemic Period
Abstrak: Kasus kelebihan berat badan pada remaja di Kabupaten Magetan masih tergolong tinggi yaitu 9,75%. Masa pandemi Covid-19 membuat aktivitas diluar rumah sangat dibatasi sehingga mempengaruhi (tingkat stres, durasi tidur, dan keragaman pangan) remaja, karena secara tidak langsung berhubungan dengan tingkat keragaman pangan. Tingkat keragaman pangan bergantung dari pengetahuan gizi yang dimiliki seseorang. Penelitian ini menggunakan desain cross sectional study dengan subyek sebanyak 75 orang yang dilakukan pada Februari-Maret 2021 di enam SMAN di Magetan. Keberadaan perbedaan data antar kelompok subyek dan korelasi antar variabel masing-masing dianalisis dengan uji Man-Whitney, Spearman dan Chi-square. Subyek berusia 16-18 tahun dengan 38 berstatus gizi normal dan 37 berstatus overweight. Sebanyak 68% subyek memiliki pengetahuan gizi seimbang yang kurang, 81,3% mengalami stres tingkat sedang, 94,7% dengan durasi tidur yang buruk dan 53,3% memiliki tingkat keragaman pangan yang kurang. Hasil uji Spearman menunjukkan tidak terdapat hubungan (p>0,05) antara karakteristik subjek (usia), karakteristik keluarga (penghasilan orangtua), pengetahuan gizi seimbang, tingkat stres, dan durasi tidur dengan tingkat keragaman pangan serta tidak terdapat hubungan (p>0,05) antara tingkat keragaman pangan dengan kejadian kelebihan berat badan pada remaja SMAN di Magetan selama masa pandemi., The overweight cases in adolescents in Magetan is relatively high, sitting at 9.75%. The Covid-19 pandemic has severely limited outside activities and it has affected the stress levels, sleep duration, and food variety of adolescents, indirectly related to their food variety. Food variety depends on a person’s knowledge regarding nutrition. This cross-sectional research involved 75 subjects and was conducted between February-March 2021 in six State Senior High Schools in Magetan. The difference of data between subject group and correlation between variables were analyzed using Mann-Whitney, Spearman and Chi-Square test. The subjects were aged 16-18 years with 38 of them had normal nutritional status and the other 37 had overweight status. There were 68% of subjects with poor knowledge of balanced nutrition, 81.3% experienced moderate stress, 94.7% had poor sleep duration, and 53.3% had lack of food variety. Further test results using the Spearman test also stated that there was no relationship (p>0,05) the subject characteristic (age), family characteristic (parent’s income), knowledge of balanced nutrition, stress levels, sleep duration and the food variety levels, and there was no relationship (p>0,05) between food variety levels and the incidence of overweight in state senior high school adolescents in Magetan during the pandemic.

Judul: Factors related to Stress Levels and Quality of Food Consumption of Overweight and Normal Hight school Adolecents during the Pandemic Period
Abstrak: Masa pandemi Covid-19 menimbulkan pembatasan aktivitas di luar rumah termasuk belajar secara daring yang memengaruhi stres akademik, konsumsi pangan dan gaya hidup (kebiasaan makan, kegiatan daring, aktivitas fisik). Penelitian ini bertujuan menganalisis faktor-faktor yang berhubungan dengan tingkat stres dan kualitas konsumsi pangan remaja SMA dengan status gizi overweight dan normal pada masa pandemi. Desain penelitian ini adalah comparative cross sectional study dengan subjek sebanyak 41 remaja dengan status gizi normal dan 41 remaja overweight. Subjek dipilih secara purposive dengan pengumpulan data primer melalui kuesioner dan wawancara. Berdasarkan hasil uji beda Mann-Whitney dan Independent Sample T-Test terdapat perbedaan yang signifikan (p<0,05) pada variabel waktu kegiatan daring (p=0,041), tingkat kecukupan energi (p=0,040), frekuensi konsumsi makanan pokok (p=0,004), protein nabati (p=0,021), dan minuman (p=0,003) antara subjek normal dan overweight. Hasil uji korelasi Spearman menunjukkan terdapat hubungan yang signifikan positif (p<0,05) antara tingkat kecukupan energi, protein, lemak, karbohidrat, dan vitamin C dengan kualitas konsumsi pangan. Variabel jenis kelamin berhubungan signifikan (p<0,05) dengan tingkat stres. Berdasarkan uji korelasi Spearman, tidak terdapat hubungan yang signifikan (p>0,05) antara tingkat stres dan kualitas konsumsi pangan dengan status gizi., The Covid-19 pandemic has caused restrictions on activities outside the home including online learning which affects academic stress, food consumption and lifestyle (eating habits, online activities, physical activity). This study aims to analyze factors related to stress levels and quality of food consumption Hight school Adolecent with overweight and normal nutritional status during the pandemic Period. The design of this study was comparative cross sectional study of 41 adolescents with normal nutritional status and 41 overweight adolescents selected by purposive sampling. Data was collected through questionnaires and interviews. Based on the results of the Mann-Whitney difference test and Independent Sample T-test, there were significant differences (p<0.05) in the online activity time variable (p=0.041), energy adequacy level (p=0.040), frequency of consumption of staple food (p=0.004), protein vegetable (p=0.021), and drinks (p=0.003) between normal and overweight subjects. The results of the Spearman correlation test showed that there was a significant positive relationship (p<0.05) between the level of adequacy of energy, protein, fat, carbohydrates, and vitamin C with the quality of food consumption. Gender variable has a significant relationship (p<0.05) with stress levels. Based on the Spearman correlation test, there is no significant relationship (p>0.05) between stress levels and the quality of food consumption with nutritional status.

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
