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: The Correlation between Nutritional Knowledge, Eating Habits, and Physical Activity with Nutritional Status among Student of SMAN 1 Kebumen
Abstrak: Prevalensi remaja gemuk usia 16-18 tahun di Indonesia meningkat pada tahun 2018. Kegemukan pada remaja dapat menimbulkan dampak negatif terkait aspek kesehatan dan psikososial. Penelitian ini bertujuan menganalisis hubungan pengetahuan gizi dengan kebiasaan makan, hubungan kebiasaan makan dengan status gizi, dan hubungan aktivitas fisik dengan status gizi siswa SMAN 1 Kebumen. Penelitian dilakukan pada Mei 2023 menggunakan desain cross sectional, melibatkan 30 remaja normal dan 30 remaja gemuk yang dipilih secara purposive. Data primer diperoleh melalui pengisian kuesioner dan wawancara berupa data karakteristik individu, karakteristik keluarga, pengetahuan gizi, aktivitas fisik, dan kebiasaan makan. Hasil uji beda menunjukkan tidak terdapat perbedaan signifikan (p>0,05) pengetahuan gizi, aktivitas fisik dan duduk, tingkat kecukupan energi dan zat gizi, asupan gula, serta kebiasaan pangan sumber gula dan lemak antara kedua kelompok subjek, namun kelompok subjek gemuk signifikan lebih banyak asupan lemaknya (p<0,05). Hasil uji korelasi menunjukkan hubungan signifikan positif antara asupan lemak dengan status gizi (p=0,01). Tidak terdapat hubungan signifikan pengetahuan gizi dengan kebiasaan pangan sumber gula dan lemak, asupan gula dan lemak, serta tingkat kecukupan energi dan zat gizi. Tidak terdapat perbedaan signifikan kebiasaan pangan sumber gula dan lemak, asupan gula, tingkat kecukupan energi dan zat gizi, dan aktivitas fisik dengan status gizi (p>0,05)., Prevalence obese adolescents aged 16-18 years in Indonesia increased in 2018. Obesity in adolescents have negative impacts related to health and psychosocial. This study aims to analyze correlation nutritional knowledge and eating habits, correlation eating habits and nutritional status, and correlation physical activity and nutritional status students at SMAN 1 Kebumen. Study was conducted in May 2023 using a cross-sectional design, involving 30 normal and 30 obese adolescents that selected purposively. Primary data was obtained through questionnaires and interviews with individual characteristics, family characteristics, nutritional knowledge, physical activity, and eating habits. There was no significant difference (p>0.05) nutritional knowledge, physical activity and duration of sitting, energy and nutrients adequacy level, sugar intake, and eating habits of food sources sugar and fat between two subject, but obese subjects had significantly higher fat intake (p<0.05). There was a significant positive correlation fat intake and nutritional status (p=0.01). There was no significant correlation nutritional knowledge with eating habits of food sources sugar and fat, intake sugar and fat, also energy and nutrients adequacy level (p>0.05). There was no significant correlation eating habits of food sources sugar and fat, sugar intake, energy and nutrients adequacy level, and physical activity with nutritional status (p >0.05).

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.
