Judul: Cemas, Depresi, dan Aktivitas Fisik selama Masa  Pandemi Covid-19 di Indonesia
Abstrak: Many have reported that covid-19 pandemic contributes to mental health issues. Therefore, this study aims to determine anxiety and depression in relation to physical activity in Indonesia during covid-19 pandemic. Anxiety and depression were assessed using the Hospital Anxiety and Depression (HAD) scale. Meanwhile, physical activity was assessed using an International Physical Activity Questionnaire (IPAQ). Both instruments were presented in online form and distributed through social media in Bahasa Indonesia. Present findings show physical activity is associated with sex, age, marital and employment status, living area, and anxiety. Anxiety and depression are associated with each other, as well as with sex, age, marital and employment status, living area, and physical activity. Body Mass Index (BMI) is associated with depression exclusively. Recent research has shown that physical activity is inversely related to adverse mental health outcomes. Chronic illnesses such as covid-19 and existent mental health problems were common predictors of increased negative effects of anxiety and depression., Banyak yang melaporkan pandemi covid-19 berkontribusi pada masalah kesehatan mental. Karenanya, penelitian ini bertujuan menentukan cemas dan depresi terkait aktivitas fisik di Indonesia selama pandemi covid-19. Cemas dan depresi dinilai menggunakan skala Hospital Anxiety and Depression (HAD). Aktivitas fisik dinilai menggunakan International Physical Activity Questionnaire (IPAQ). Kedua instrumen diberikan dalam bentuk formulir daring dan disebarluaskan melalui media sosial dalam Bahasa Indonesia. Hasil studi menunjukkan aktivitas fisik berasosiasi dengan jenis kelamin, usia, status perkawinan dan pekerjaan, tempat tinggal, dan cemas. Cemas dan depresi berasosiasi satu sama lain, serta dengan jenis kelamin, usia, status perkawinan dan pekerjaan, area tempat tinggal, dan aktivitas fisik. Body Mass Index (BMI) hanya berasosiasi dengan depresi saja. Penelitian terbaru menunjukkan bahwa aktivitas fisik berbanding terbalik dengan hasil kesehatan mental yang merugikan. Penyakit kronis seperti covid-19 dan masalah kesehatan mental bawaan adalah prediktor umum dari peningkatan efek negatif dari cemas dan depresi.

Judul: Relationship between Intensity of  Using Online Food Delivery Applications and Physical Activity with College  Student’s Nutritional
Abstrak: Meningkatnya intensitas penggunaan pesan antar online serta rendahnya aktivitas fisik selama pandemi Covid-19 dapat memberi dampak yang buruk bagi kesehatan. Intensitas penggunaan aplikasi pesan antar online dan status gizi berhubungan dengan tingkat ekonomi seseorang. Penelitian ini bertujuan untuk menganalisis hubungan antara intensitas penggunaan aplikasi pesan antar makanan online, aktivitas fisik, uang saku, dan pendapatan keluarga dengan status gizi selama pandemi Covid-19. Desain penelitian ini adalah cross sectional dengan jumlah sampel 94 subjek mahasiswa aktif IPB yang dipilih secara purposive sampling. Pengumpulan data dilakukan melalui wawancara dan self-administrated secara online. Tidak terdapat hubungan yang signifikan antara status gizi dengan intensitas penggunaan aplikasi pesan antar makanan online aktivitas fisik, uang saku, dan pendapatan keluarga (p>0,05). Pengguna aplikasi pesan antar makanan online agar dapat mengontrol pemesanan makanan dan meningkatkan aktivitas fisik walau hanya di dalam rumah agar memiliki pola hidup yang lebih sehat.

Judul: Synthesis of Molybdenum Trioxide (MoO3) by Electrochemical Method for Electrochromics Application
Abstrak: Molybdenum trioxide (MoO3) thin films have been deposited on glass substrates by electrochemical method using ammonium heptamolybdate tetrahydrate ((NH4)6Mo7O244H2O). The films were deposited onto glass substrates as the control temperature at 25○C and annealing treatment at 350○C for 30 mins. The MoO3 thin films were investigated by UV-Vis, X-ray diffraction techniques (XRD), Scanning Electron Microscopy (SEM). The JCPDS card show that orthorhombic MoO3 (α- phase) has been formed. Molybdenum trioxide MoO3 formation was also confirmed by JCPDS card no. 35-0609. The SEM photographs revealed that the spherical and rod-like morphology and their grains size increased with increasing of heating temperatures. The measurement results show that the MoO3 thin film prepared at 350°C transmited about 80% of the visible spectrum. The effect of different heat treatments on surface morphology, thickness and optical properties of the films are discussed in this thesis.
