Abstract

Fusarium oxysporum is the causal agent of damping-off disease. The fungus attacks seedlings of many plant species, including Acacia mangium. In order to effectively control the disease, detailed information on how the fungus infects seedlings of A. mangium and how the plant responds to the fungal infection is essentially needed. The objectives of this research were to investigate: (1) the infection process of F. oxysporumon seedlings of A. mangium, (2) the defence response of A. mangium seedling to infection by F. oxysporum. The fungal pathogen was identified, followed by performance of pathogenicity test. The infection process was followed by macroscopic observation as well as microscopic observation. The result indicated that fungal spore germination was observed at two-day post inoculation in planta. At four-daypost inoculation, hyphae of F. oxysporum had penetrated the collar root of A. mangium seedling via stomata aperture. In addition, fungal hyphae had grown intercellulary in to the vascular tissue. Correspondingly, hypersensitive response was also detected at the stomata aperture. However, this defence mechanism is not effective in stopping the fungus since F. oxysporum is a necrotropic pathogen. Moreover, accumulation of lignin, but not callose, was observed.

Abstract

Perubahan suhu global dapat mengubah sistem iklim, terutama presipitasi melalui peningkatan konveksi. Kondisi tersebut berpotensi terhadap kenaikan intensitas dan frekuensi hujan ekstrem. Hujan ekstrem merupakan sebab dari bencana hidrometeorologi seperti banjir, banjir bandang, dan kekeringan. Selain itu, pemanasan global berakibat pada El Nino/ Southern Oscillation (ENSO) dengan durasi kala ulang lebih pendek. ENSO berpengaruh terhadap iklim di sekitar wilayah monsunal Indonesia, terutama bagian timur.  Jawa bagian timur mengalami kekeringan ekstrem ketika ENSO positif kuat. Penelitian ini bertujuan untuk: a) mengidentifikasi perubahan curah hujan ekstrem di Bengawan Solo Hilir tahun 1979-2017; b) menjelaskan kejadian hujan ekstrem saat fenomena ENSO (El Niño/ Southern Oscillation). Penelitian menggunakan data curah hujan harian dari 16 stasiun hujan di Bengawan Solo Hilir mulai 1979 – 2017 (39 tahun) yang telah diuji homogenitas dan konsistensi. Data tersebut digunakan untuk memperoleh indeks ekstrem hujan berupa Rx1hari, Rx5hari, P95, P99, dan intensitas hujan harian. Tren hujan monotonik dihitung menggunakan statistik Mann-Kendall, adapun besarnya perubahan dianalisis menggunakan uji Sen’s slope. Hubungan antara hujan ekstrem dengan kejadian ENSO diketahui berdasarkan nilai korelasi Spearman-rank. Hasil penelitian menunjukkan bahwa sebagian besar stasiun hujan bagian timur-selatan mengalami penurunan hujan ekstrem berupa Rx1hari, P95, dan intesitas hujan harian (tren negatif) justru pada puncak musim hujan (Desember – Januari – Februari) dan transisi penghujan-kemarau (Maret-April-Mei). Penurunan hujan harian maksimum (Rx1hari) pada rentang 0,3 mm/tahun hingga 1,1 mm/tahun.  Kejadian ENSO tidak otomatis berakibat pada intensitas hujan ekstrem skala harian. Indeks ENSO dapat digunakan untuk analisis indeks ekstrem dengan skala kumulatif antarmusim maupun antartahun.  Hasil ini mengindikasikan bahwa variabel ENSO lebih tepat digunakan pada analisis kekeringan dan tidak berkaitan erat dengan bencana hidrometeorologi dalam skala pendek seperti banjir maupun banjir bandang.

Abstract

Kegiatan penambangan minyak dan gas bumi memberikan dampak pencemaran lingkungan yang disebabkan karena hasil sampingnya yang berupa air terproduksi. Di beberapa tempat di Indonesia kegiatan produksi ini dilakukan dengan cara tradisional dengan membuat gorong - gorong, salah satunya yang berada di Desa Kedewan, Bojonegoro. Pemakain alat yang sederhana dalam proses produksi serta tidak adanya IPAL menyebabkan kegiatan penambangan secara tradisional ini memberukan dampak terjadinya pencemaran terhadap kualitas air sungai. Penerima air libah berupa air terproduksi dari kegiatan ini adalah Sungai Kedungrupit dan Sungai Kaligaling. Tujuan dari penelitian ini adalah untuk menganalisis konsentrasi air limbah yang dihasilkan dan juga menganalisis konsentrasi air sungai akibat kegiatan penambangan. Kegiatan penambangan tradisional minyak bumi di Desa Kedewan menghasilkan konsentrasi air terproduksi yang masih melebihi baku mutu sesuai Peraturan Menteri Lingkungan Hidup No. 19 Tahun 2010. Parameter yang terlampaui yaitu TDS dan COD. Sedangkan untuk kualitas air Sungai Kedungrupit dan Sungai Kaligaling setelah menerima air terproduksi kegiatan penambangan minyak bumi termasuk kategori tidak memenuhi baku mutu untuk air kelas II sebagaimana terlampir dalam PP No.82 Tahun 2001. Parameter yang terlampaui untuk baku mutu kelas II yaitu parameter COD, TDS, NH?-N, serta, Minyak dan Lemak. Berdasarkan hasil analisis parameter fisika dan kimia air terproduksi di Desa Kedewan, maka perlu diadakan tindak lanjut dalam pengendalian pencemaran air sungai dengan membangun IPAL dan diperlukan adanya koordinasi dengan Pemerintah setempat agar dikeluarkan kebijakan yang terkait.
