Judul: Rancang bangun sistem penunjang keputusan kelompok untuk penentuan strategi pengembangan usaha
Abstrak: Strategi pengembangan usaha merupakan salah satu strategi dalam perusahaan multi-usaha. Keputusan yang bersifat strategi dalam suatu perusahaan ditentukan oleh sekelompok perencana strategi. Anggota perencana strategi biasanya manajer tingkat menengah ke atas dan pemilik perusahaan. Kelompok tersebut seringkali kesulitan untuk mengadakan pertemuan lengkap karena masing-masing mempunyai kesibukan yang berbeda. Model STRAKEM diharapkan dapat mengatasi kesulitan-kesulitan tersebut. Model STRAKEM terdiri dari lima buah sub model yaitu Sub Model EKSTERNAL, Sub Model INTERNAL, Sub Model STRATEGI, Sub Model IDEPROYEK, dan Sub Model PROSTUDI. Sub Model EKSTERNAL terdiri dari Paket SINLINK dan Paket ESANDILI. Paket SINLINK adalah suatu Sistem Informasi Ekseku- tif tentang lingkungan usaha. ESANDILI merupakan paket Sistem Ahli untuk analisis dan diagnosis lingkungan usaha. ESANDILI terbagi menjadi dua yaitu ANDIPEL dan ANDIAN. ANDIPEL untuk melihat peluang usaha dan ANDIAN untuk melihat ancaman usaha. Sub Model INTERNAL terdiri dari Paket SIPRESUS dan Paket ESPRESUS. Paket SIPRESUS merupakan Sistem Informasi Eksekutif mengenai prestasi unit-unit usaha dan ESPRESUS merupakan Sistem Ahli untuk penentuan prestasi unit-unit usaha. Sub Model PROSTUDI terdiri dari dua paket yaitu ANFIS dan PROPHA. Paket ANFIS adalah program penunjang keputusan indi- vidu untuk membantu perhitungan parameter-parameter finansial proyek industri. Paket PROPHA merupakan paket komputerisasi teknik Proses Hirarki Analitik. Verifikasi model STRAKEM dilakukan untuk tahap pengambilan keputusan kelompok. Pada skenario pertama pengambilan keputusan bersama tahap satu (sub model STRATEGI) diperoleh keputusan untuk menutup peternakan dan mencari alternatif usaha lain. Pada tahap selanjutnya diperoleh keputusan bahwa alternatif usahanya adalah industri pestisida alami dari nimba. Pada skenario kedua diperoleh keputusan untuk membuka usaha baru yang relevan dengan usaha yang lama, mencari alternatif pemanfaatan kayu karet, dan membuka industri mebel dari kayu karet. Pada pengumpulan ide proyek hanya diperoleh satu ide proyek yaitu industri mebel dari kayu karet. Dalam kedua verifikasi yang dilakukan hanya terdapat sebuah ide proyek, sehingga penilaian dengan PHA tidak perlu dilakukan.

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.
