Judul: Keefisienan Masa Belajar di Fakultas Pertanian dan Fakultas Peternakan Universitas Andalas Tahun Akademik 1970 sampai 1974
Abstrak: Tujuan dari penelitian ini ialah. menilai keefisienan masa belajar sarjana pertanian dan peternakan tingkat S1 di Fakultas Pertanian dan.Fakultas Peternakan Universitas Andalas tahun akademik 1970 sampai 1974 serta mengusut faktor-faktor yang mempengaruhi keefisienan ini. Keefisienan masa belajar sarjana pertanian dan sarjana peternakan di Fakultas Pertanian dan Fakultas Peternakan Universitas Andalas tahun akademik 1970 sampai 1974 dinilai masih rendah. Keefisienan masa belajar sarjana pertanian di Fakultas Pertanian lebih tinggi nilainya dari keefisienan masa belajar sarjana peternakan di Fakultas Peternakan Universitas Andalas.Dari 366 orang mahasiswa seluruh angkatan tahun 1970 sampai 1974 di Fakultas Pertanian, lulus 230 orang, putus kuliah 106 orang dan masih kuliah 30 orang sampai tahun 1982. Lulusan menyelesaikan pendidikannya antara 6 sampai 12 tahun. Mahasiswa yang putus kuliah lama pendidikannya antara 1 sampai 2 tahun. Mahasiswa yang masih kuliah sampai tahun 1982 diperkirakan akan lulus pada tahun 1983, berarti lama penyelesaian pendidikannya antara 10 sampai 14 tahun. Faktor-faktor ini menyebabkan keefisienan pendidikan E, sebagai salah satu komponen dari keefisienan masa belajar E nilainya menjadi rendah. Dari 230 orang lulusan ini tidak ada yang menyelesaikan pendidikan dalam lima tahun, sehingga lulusan yang berusia 23 tahun (jadi yang mempunyai harapan masa pengabdian kepada negara 37 tahun) tidak ada. Faktor ini menyebabkan orang-tahun pengabdian kenyataan kurang nilainya dari orang pengabdian semestinya kepada negara. Dengan demikian maka nilai keefisienan masa pengabdian E2 menjadi rendah. Keefisienan pendidikan El dan keefisienan masa pengabdian E2 yang bernilai rendah menyebabkan keefisienan masa belajar E juga akan menjadi rendah nilainya.

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.
