Judul: Perbedaan kualitas gizi makan siang katering dengan bekal Anak Sekolah Dasar
Abstrak: Tujuan penelitian ini untuk mengetahui perbedaan kualitas gizi makan siang katering dengan bekal pada anak sekolah dasar. Desain yang digunakan adalah cross sectional, terdiri dari 25 siswa kelompok katering dan 28 siswa kelompok bekal. Hasil menunjukkan rata-rata asupan energi, vitamin A, vitamin C, kalsium dan zat besi makan siang kelompok katering lebih tinggi, namun rendah protein dibandingkan kelompok bekal. Kualitas makan siang subjek katering signifikan lebih tinggi dibanding dengan subjek bekal. Terdapat perbedaan yang nyata (P<0.05) pada asupan energi dan zat gizi makan siang. Kontribusi energi makan siang tidak menunjukkan adanya perbedaan, namun pada keragaman menu makan siang terdapat perbedaan yang nyata (P<0.05). Terdapat hubungan yang signifikan (P<0.05) antara kontribusi energi makan siang dengan prestasi belajar, namun tidak terdapat hubungan antara kontribusi energi makan siang dengan status gizi. Keragaman makan siang tidak berhubungan dengan prestasi belajar dan status gizi.

Judul: Analisis Konsumsi Bekal Makanan dari Rumah dan Katering Sekolah Kaitannya dengan Status Gizi Siswa SD Berkarakter Al-Biruni Bekasi.
Abstrak: Konsumsi pangan dapat mempengaruhi status gizi. Anak-anak lebih banyak menghabiskan waktu di sekolah, sehingga konsumsi pangan di sekolah harus diperhatikan. Penelitian ini bertujuan untuk menganalisis konsumsi makan siang yang berasal dari bekal makanan rumah dan katering sekolah serta kaitannya dengan status gizi siswa SD Berkarakter Al-Biruni Bekasi. Desain penelitian yang digunakan adalah cross sectional study dengan total sampel 38 orang, yaitu 21 siswa pada kelompok katering sekolah dan 17 siswa pada kelompok bekal dari rumah. Penelitian dilaksanakan pada September-November 2019 di SD Berkarakter Al-Biruni Bekasi. Data diperoleh dari sekolah, pengukuran antropometri, dan penilaian konsumsi pangan (food recall 24 jam, food record, food weighing, dokumentasi). Total konsumsi pangan sehari kedua kelompok lebih tinggi pada hari sekolah daripada hari libur. Kontribusi energi dan protein makan siang kedua kelompok sudah memenuhi 30-35% total kebutuhan sehari, dan zat gizi lainnya belum memenuhi kebutuhan sehari. Kualitas konsumsi makan siang kedua kelompok sebagian besar tergolong belum berkualitas. Terdapat hubungan yang signifikan antara asupan protein dan zat besi makan siang dengan status gizi kelompok katering (p<0.05). Tidak terdapat hubungan signifikan antara konsumsi makan siang dengan status gizi kelompok (p>0.05). Terdapat perbedaan status gizi yang nyata antara kedua kleompok (p=0.004).

Judul: Characteristic of Overshooting Top (OT) Based on  Himawari  8  Satellite  as  a  Convective  Cloud  Feature  that  Generates  Extreme Weather in the Java Island Region
Abstrak: Overshooting Top (OT) is a feature at the top of a convective cloud that is associated with extreme weather. Research on OT in tropical Indonesia is still very limited. The existence of geostationary satellites with wide area coverage and fast frequency observations is useful for observing the fast dynamics of the OT life cycle. Therefore, this study intends to analyze the relationship between OT and extreme weather, updraft and thermodynamic conditions of OT when extreme weather occurs, the best objective method for detecting OT in the day time and night time, and the spatiotemporal distribution of OT in the tropical region of Java Island during the 2018-2021 period. Based on visual analysis using visible channel and Himawari 8 sandwich products, 87% of extreme weather events in Java were accompanied by the appearance of OT. It indicates that the presence of the OT pattern is a convection cloud pattern or feature that is closely related to extreme weather events for the Java Island region. The existence of a time lag between the appearance of OT and extreme weather events on Java Island indicates that the OT of convection cloud can be used as a precursor or nowcasting for the appearance of extreme weather. Most of the convective cloud OT features during extreme weather events on Java Island have altitude that were only able to exceed the altitude of the equilibrium level and few were able to exceed the tropopause level of 9 km – 16 km. The difference in atmospheric conditions during extreme weather events on Java Island, which is in the tropics and subtropics, is a strong and unstable convective energy condition characterized by a larger CAPE, as well as unstable KI, LI, SI and TTI values. It is offset by kinematic factors in the form of a weak vertical wind shear (bulk wind shear 0-6 km) and a higher freezing point height. The difference between extreme weather events in the Java Island region and other tropical regions compared to subtropical regions is the strong updraft speed of convection clouds. The IRW Texture COMB algorithm based on the IRW-Texture Gradient modification and the COMB algorithm shows a significant increase in quality for detecting OT and non-OT pixels in Java. Rainy days with rainfall > 50 mm/day are very common in areas with an altitude of > 500 m. On the other hand, the level of convection activity which is indicated by the presence of OT and lightning is significantly reduced in this area. OT of convective clouds appear more frequently during the DJF season and less frequently during the JJA season. OT often appears during the day time and rarely at night time. Most OTs appear in the central part, away from the south and north coasts of Java Island during the day, while OTs that appear near the south and north coasts of Java Island can appear in the morning or afternoon.
