Flood disasters in Baleendah District (Bandung Regency) which occur every year often cause hundreds of hectares of paddy fields to fail in harvesting. Meanwhile, rapid land use changes occurred in the plain area has caused many paddy fields have turned into settlements, while many of slopes of hills area have turned into barelands caused by rock mining activities. This kind of activity can reduce slope stability and facilitate landslides in the future. Studying the natural hazards for this region becomes important for disaster mitigation needs in the future. The purpose of this study is to map land use and assess flood and landslide hazards in Baleendah District. The research method includes land use visual interpretation from Quickbird imagery, Pairwise Comparison analysis to obtain the weight and score of flood and landslide hazards parameters, and Multi Criteria Evaluation (MCE) analysis to assess the natural hazards. The results showed that the interpretation of Quickbird imagery produced 12 types of land use dominated by settlement types (31.17%) and rice fields (30.90%). From Pairwise Comparison analysis, it was found that the sequence of weights of flood hazard parameters were inundation duration (0.50), inundation frequency (0.33), and inundation depth (0.17), while for landslide hazards were slope steepness (0.50), land use (0.33), and slope form (0.17). Based on the participatory flood-prone mapping, it was found that flood-prone areas were only spread in one village, i.e. Andir Village, while for landslide-prone areas were spread in 5 villages. The results of Multi Criteria Evaluation (MCE) analysis showed that the high and medium class of flood hazards covered 128.99 ha and 34.76 ha respectively, while high, medium and low class of landslide hazards covered 281.62 ha, 940.84 ha and 124.69 ha respectively. Controlling land use change is a good choice to do in this region to reduce natural hazards in the future.

Tingginya kejadian longsor di Kabupaten Sukabumi menjadi penyebab diperlukannya data dan informasi kawasan yang memiliki potensi longsor. Identifikasi potensi longsor dapat dilakukan melalui berbagai pendekatan dimana metode statistik adalah pendekatan yang paling banyak digunakan untuk pemetaan longsor. Maka dari itu, tujuan penelitian ini adalah memprediksi longsor di Kabupaten Sukabumi. Metode penelitian yang digunakan adalah metode Weight of Evidence (WoE), Logistic Regression (LR), dan kombinasi WoE-LR. Hasil pengujian menunjukkan bahwa parameter yang layak digunakan menjalankan model adalah jarak dari jalan, jarak dari sungai, jarak dari patahan, SPI, TWI, Elevasi dan Lereng. Hasil metode WoE menunjukkan bahwa parameter elevasi <300 m, jarak dari jalan >200 m dan jarak dari sungai >100 m merupakan kelas parameter yang tidak baik untuk memprediksi longsor. Sebaliknya, parameter lereng 8–15%, jarak dari jalan 31–70 m dan elevasi 700–800 baik digunakan untuk memprediksi longsor. Pada metode LR, parameter elevasi dan jarak dari jalan secara signifikan berpengaruh terhadap longsor. Hasil metode kombinasi WoE-LR menunjukkan bahwa parameter jarak dari jalan dan SPI merupakan parameter yang kurang baik untuk memprediksi longsor. Sebaliknya, parameter lereng dan TWI merupakan parameter yang paling baik untuk memprediksi bahaya longsor. Berdasarkan pengujian ketiga metode tersebut, dapat disimpulkan bahwa metode kombinasi WoE-LR adalah metode yang paling baik dalam memprediksi bahaya longsor di wilayah penelitian.

Penyakit busuk lunak (PBL) yang disebabkan oleh Pectobacterium carotovorum subsp. carotovorum atau Pseudomonas viridiflava merupakan kendala utama dalam budidaya anggrek. Serangan patogen tersebut sangat merugikan petani, mengingat biaya investasi produksi anggrek tergolong tinggi. Oleh karena itu patogen tersebut harus dikendalikan menggunakan metode pengendalian yang ramah lingkungan, yaitu dengan mengaplikasikan biobakterisida berbahan aktif rizobakteri, seperti Bacillus subtilis dan Pseudomonas fluorescens. Tujuan penelitian ini ialah (1) mendapatkan komposisi bahan aktif dan bahan pembawa biobakterisida yang efektif mengendalikan penyakit busuk lunak pada anggrek Phalaenopsis, (2) mengetahui perubahan reaksi kimia formula biobakterisida dan pertumbuhan populasi bahan aktif (rizobakteri B. subtilis dan P. fluorescens) pada kondisi sebelum dan setelah difermentasikan, dan (3) mengetahui kompatibilitas antara B. subtilis, P. fluorescens, dan bahan pembawa biobakterisida. Percobaan dilaksanakan mulai Bulan Mei sampai dengan Desember 2009 di Laboratorium Bakteriologi Departemen Proteksi Tanaman, Institut Pertanian Bogor, dan Laboratorium Bakteriologi serta Rumah Kaca, Balai Penelitian Tanaman Hias, di Segunung, Cianjur, Jawa Barat. Ruang lingkup penelitian meliputi pembuatan propagul rizobakteri sebagai bahan aktif biobakterisida, pembuatan formula biobakterisida, uji viabilitas bahan aktif, dan uji kemangkusan biobakterisida pada tanaman anggrek di rumah kaca. Hasil penelitian menunjukkan bahwa (1) perlakuan gabungan antara B. subtilis B12 dan P. fluorescens Pf10 yang difermentasikan dalam media ekstrak kotoran cacing (kascing) dan molase, merupakan perlakuan yang konsisten dapat menekan PBL pada anggrek Phalaenopsis dengan persentase penekanan sebesar 80%, (2) reaksi kimia formula biopestisida pada kondisi sebelum dan setelah fermentasi diindikasikan dengan perubahan pH basal medium yang sebelum fermentasi menunjukkan pH 3,75 dan berubah menjadi pH 3,50 setelah difermentasikan. Pertumbuhan populasi mikrob antagonis setelah fermentasi meningkat secara signifikan bila dibandingkan pada kondisi sebelum difermentasikan, dan (3) isolat bahan aktif (B. subtilis dan P. fluorescens) bersifat kompatibel dengan bahan pembawanya (ekstrak kascing dan molase).
