Judul: Formulasi Pelet Berbahan Aktif Trichoderma sp. untuk Pengendalian Penyakit Rebah Kecambah (Pythium sp.) pada Tanaman Mentimun
Abstrak: Cucumber (Cucumis sativus Linn. ) is an important agricultural comodity in Indonesia, but the production rate of it still low. One of the factors that causes the low productivity is plant diseases. Damping-off disease often causes the damage of cucumber plant, early stage of cucumber plant growth. It is caused by Phytium sp, a fungus that lives in the soil as soilborne disease. The controlling effort of this disease have been done, for example by using Trichoderma sp. as bio-agent, but the utilization of the bio-agent still not practical so it is difficult to be applied in field. The utilization of Trichoderma sp as a pallet formulation is more effective to be implemented because of the small size and easily moved. The purpose of this research is to produce the pellet formulation with active material of Trichoderma sp. with high nutritious, cheap and easy carrier. This research uses two tests, invitro and invivo. The invitro test uses six different pellet formulations, DAT, UAT, TAT, PAT, DDS and ATS. The best formulation in invitro test byare UAT and DDS because Trichoderma sp can grow very well in these pellet formulation and the raw material of them are cheap and easily obtained. The DDS and UAT can suppress the attack of pathogenic fungus, Pythium sp. on the test with invivo

Judul: Seleksi bakteri endofit untuk pengendalian penyakit rebah kecambah (Pythium sp.) pada tanaman mentimun
Abstrak: Damping-off is one of the major diseases that often attack almost any plants in the nursery phase. Cucumber is one of the main hosts for damping-off disease caused by Pythium sp. The use of biocontrol agents such as endophytic bacteria is one an alternative for controlling plant diseases. The objective of this study was to isolate an endophytic bacteria from betel and paddy and to select their potency in controlling damping-off disease on cucumber. The isolation of endophytic bacteria was carried out through surface sterilization method with 70% alcohol, 4% NaOCl and sterile distilled water. A total of 50 isolates of endophytic bacteria were isolated from the betel and two isolates from the paddy. Based on antibiosis test result, growth and suppression of endophytic bacteria against damping-off, four isolates AS2, BS14, Ci6, and Ci10 were known to have ability in suppressing the disease severity of damping-off up to 87.6% and able to increase the plant growth of cucumber in a greenhouse.

Judul: Pola dan Variabilitas Arus di Wilayah Laut Bali-Laut Flores dari Hasil Model INDESO Tahun 2008-2014
Abstrak: Dinamika laut di wilayah Laut Bali dan Laut Flores dipengaruhi baik oleh dinamika Arus Muson dan Arlindo Makassar, maupun intrusi gelombang Kelvin dari ekuator Samudera Hindia via Selat Lombok. Tujuan penelitian ini adalah untuk mengkaji pola dan variabilitas arus, struktur menegak arus, serta koherensi arus di Laut Bali-Laut Flores dari hasil model INDESO tahun 2008-2014. Pola arus di wilayah studi dicirikan oleh arus laut yang kuat mengalir ke arah selatan (Arlindo Makassar), serta pusaran arus di Laut Bali. Percabangan Arlindo terjadi di utara Lombok, dimana sebagian Arlindo masuk Selat Lombok dan sebagian lagi berbelok ke timur menyusuri Laut Flores. Variasi musiman sirkulasi laut ditandai dengan menguatnya Arlindo pada musim timur, serta terbentuknya pusaran arus dan kelokan arus muson yang mengalir ke arah timur pada periode musim barat. Struktur Arlindo di lintang geografis 8 °S, dicirikan oleh inti Arlindo yang lebih dalam (220 m) dan lebih luas dengan kecepatan arus yang lebih kuat dalam musim timur dibandingkan dengan musim barat. Estimasi transpor volume dari Arlindo di lintang ini adalah sekitar 2 Sv (musim barat) dan 4.7 Sv (musim timur). Variabilitas arus berfluktuasi pada rentang periode dari intra-musiman sampai tahunan. Koherensi arus yang tinggi pada periode 1 hingga 2 bulanan dengan beda fase positif dari Samudera Hindia menuju Selat Lombok bagian utara menunjukkan bahwa adanya pembelokan arus di Selat Lombok akibat perambatan Gelombang Kelvin.
