Judul: Pengujian Formulasi Konsorsium Bakteri terhadap Penyakit Blas Leher (Neck Blast ) pada Tanaman Padi
Abstrak: Pemanfaatan bakteri sebagai bentuk pengendalian hayati dalam mengurangi serangan penyakit padi perlu dilakukan. Penelitian ini bertujuan untuk mengetahui keefektifan formula konsorsium bakteri sebagai pengendali penyakit blas leher (Neck Blast) pada tanaman padi. Perlakuan formula isolat yang digunakan masing-masing adalah A2 (B. firmus E65), A6 (B. firmus E6 + P. aeruginosa C32b + B. cereus II.14), A8 (B. firmus E6 + P. aeruginosa C32b + B. cereus II.14+S. marcescens E31) serta penambahan bahan agensia yang diberikan pada masing-masing kode perlakuan. Formula bahan agensia yang digunakan berupa talk (T), bentonit (B), dan pupuk organik granula (P). Pengujian secara in vitro dari konsorsium suspensi A6 dan A8 serta formula dengan bahan agensia (AST, dan A8P) dapat menghambat pertumbuhan P. oryzae masing-masing sebesar 46,29%, 54,45%, 40,00%, 42,59%. Hasil uji efektivitas formulasi terhadap intensitas serangan blas leher menunjukkan intensitas serangan terkecil yaitu ISA8 (13,89%), IPA6 (13,44%), dan ITA6 (14,59%). Selain itu pemberian formula memberikan pengaruh tehadap jumlah anakan total, jumlah malai setelah 94 hari tanaman (hst) yaitu dengan pemberian formula IPA6 sebesar 25 untuk jumlah anakan total dan 12,3 untuk jumlah malai. Pemberian formulasi juga berpengaruh nyata terhadap bobot basah dan bobot kering tanaman. Hasil tersebut menunjukkan bahwa penyemprotan dengan formula IPA6, ITA6 dan ISA8 pada tanaman padi memberikan pengaruh penghambatan terhadap penyakit blas leher. Pemberian formula IPA6 memberikan pengaruh terhadap jumlah anakan total dan jumlah malai serta berpengaruh nyata terhadap berat biomassa tanaman padi Inpari 13.

Judul: Seleksi dan Formulasi Konsorsium Bakteri untuk Mengendalikan Penyakit Blas (Pyricularia oryzae) pada Tanaman Padi
Abstrak: Penyakit blas yang disebabkan cendawan Pyricularia oryzae merupakan salah satu hambatan pada produksi padi lahan kering maupun lahan basah. Penelitian ini dilakukan untuk mencari agen pengendali hayati (konsorsium bakteri) untuk mengendalikan penyakit blas. Metode pertama yang dilakukan yaitu uji kompatibilitas in vitro bakteri Bacillus firmus E65, Serratia marcescens E31, Pseudomonas aeruginosa C32b, Bacillus cereus II.14, serta kombinasi konsorsiumnya terhadap cendawan P. oryzae. Hasil uji menunjukkan 2 perlakuan yaitu A2 yang menggunakan isolat E65 dan perlakuan A6 yang menggunakan konsorsium E65, II.14, dan C32b memiliki luas daerah penghambatan terhadap P oryzae terbaik dengan persentase penghambatan 73-85% dan sebesar 66-83%. Pembuatan formulasi dilakukan untuk dua perlakuan terbaik dengan bahan pembawa talk, bentonit, minyak, dan kaldu nutrien (suspensi). Hasil aplikasi in vivo menunjukkan formulasi suspensi memiliki potensi penekanan blas paling baik.

Judul: Kasus: Konsumen Remaja di Tiga One Stop Shopping Mall di Jakarta
Abstrak: Teenager is one of the most potential markets for producers. The consumptive lifestyle is one of the reasons. It’s all due to peer pressure among friends, unrealistic lifestyle, and also have a tendency to be wasteful in monetary usage. Through their lifestyle, teenager can show their characteristic and social class among their people. That is why producers are using this type of attribute between teenagers to be their market. The purpose of this research is to identify the characteristic of regular “shopping mall” lifestyle with teenager “shopping mall” lifestyle. These research using quantitative approach. This approach was done using a survey method. The technique to obtain a respond was done using purposive sampling with 40 people of responder. The data that I obtained was primary data and secondary data. Primary data were obtained using survey method, where secondary data were obtained from the data that was previously exist. Frequency table and cross tabulation were the technique to obtain the quantitative data. Shoppers are usually around 15-18 years old and also in high school. They go to average school and they usually spend their time hang-out in café, sightseeing, sports, and visiting their friend’s house. This teenager uses their own car to go to school, and their father’s job is an entrepreneur and their mother does not go to work or as a house wife. Shoppers’ family uses their money for recreation and education. This shopper uses cash as a payment. Shopper has a tendency to use electronic media as their primary media. Magazine is used as their written media and internet is used as the electronic media. According to the research, I can conclude there are three types of shoppers, which are real shoppers, socialize shoppers, and beginner shoppers. Shoppers are usually a high school or college student. The majority of these three types of shoppers are usually the same, which are go to cinema, eat and shopping. They commonly used two to three hour at mall with their friends because mall are comfortable and calming. Shoppers main concern are the price, model and the brand of the product. The difference between the three types of shoppers are beginner Socialize shoppers and shoppers ages are between 15 - 18 years old, while real shoppers ages between 19 to 22 years. Real shoppers and beginner shoppers usually are women and Socialize shoppers are men. The mass media are often used by real shoppers are print media, while the beginner shoppers and socialize shoppers more likely to use electronic media. Real shoppers spend more than one million rupiah, while socialize shoppers spend five hundred to one million dollars, and beginner shoppers spend their money under five hundred thousand rupiah. Real shoppers go to the mall in order to fill his spare time, while socialize shoppers tend to socialize with friends. Meanwhile beginner shoppers aim to buy their daily needs.
