Abstrak: The application of VAM and chicken manure dose was investigated toward growth and production of maize using splitplot design by complete randomized design methode. The first factor as the main plot is VAM (without VAM and with VAM) and the second factor as subplot is the dose of chicken manure (0, 5, 10, 15, and 20 tons/ha). Doses of chiken manure 0 ton/ha was used to determine 100 % inorganic fertilizer and the other dose of chicken manure was used to determine 50 % of inorganic fertilizer. Statistically, the application of the VAM did not provide significant effect on the growth and yield of maize. However, at 9 weeks after planting, the use of VAM provide more high-than plant height without the use of VAM. In several treatment with VAM showed growth and higher production than without VAM. Application doses of chicken manure showed a significant effect on the growth and yield of corn. Doses of chicken manure give a linear response of plant height at 9 week after planting and corn grains.

Abstrak: This research aimed to get optimal rate of manure and proper manure application to increase crop production of bambara groundnut. The research was conducted from February to June 2014 at IPB experimental field. The experiment used factorial in randomized complete block design with two factors and three replications. The first factor was rates of chicken manure with four i.e. 0, 5, 10, and 15 tons ha-1. The second factor was 2 application methods of manure i.e. spread over the soil surface and put in planting row. Growth and production of bambara groundnut was insignificantly affected by neither manure rates nor manure applicaton methods. Although there was not significant effect of manure rates, there was indication that the highest yield (number of pods per plant) of bambara groundnut could be achieved with the addition of 6.8 tons manure ha-1. Bambara groundnut crop were heavily infected by desease at 7 weeks after planting, this might have resulted in insignificant effect of treatments to all variables.

Judul: Siklon Tropis di Wilayah Western North Pacific ketika Fase Kuat Boreal Summer Intraseasonal Oscillation (BSISO).
Abstrak: Kejadian siklon tropis di Belahan Bumi Utara (BBU) dominan terjadi pada musim panas atau awal musim gugur, yang kemungkinan bertepatan dengan aktivitas konvektif Boreal Summer Intraseaonal Oscillation (BSISO) antara bulan Mei-Oktober. Penelitian ini mengkaji keterkaitan fenomena BSISO terhadap pembentukan dan karakteristik siklon tropis di wilayah WNP. Analisis komposit dilakukan untuk melihat kondisi rata-rata dari kedua fenomena tersebut per fase BSISO, berdasarkan data kejadian siklon tropis wilayah WNP, data harian anomali SST, indeks dan fase BSISO. Analisis korelasi dilakukan untuk melihat keterkaitan kedua fenomena ini, serta analisis karakteristik siklon tropis yang meliputi intensitas (Skala Saffir-Simpson) dan masa hidupnya. Selama periode 2002-2011, kejadian siklon banyak ditemukan pada fase 5 sampai 8 BSISO1. Kejadian siklon tropis juga banyak terjadi pada fase 2 dan 8 BSISO2. Indeks BSISO menunjukkan korelasi negatif kuat dengan suhu muka laut ketika terjadi pembentukan siklon di fase 8. BSISO1 dan BSISO2 memiliki nilai korelasi masing-masing sebesar 0.807 dan -0.585 pada selang kepercayaan 95% dan taraf nyata 0.05. Pada kedua BSISO, karakteristik dominan yang terbentuk adalah badai tropis dan siklon tropis kategori 2 yang memiliki tingkat kerusakan moderat (sedang) dengan masa hidup tersingkat 8 hari dan terlama 21 hari. BSISO1 memiliki keterkitan terhadap siklon tropis berintensitas tinggi yaitu siklon kategori 4, yang dapat menimbulkan kerusakan ekstrim dengan masa hidup 12 hari.
