Species of Ceratocystis are well-known wound related pathogens many tree species, including commercially planted Acacia spp. Recently, several isolates were collected from wilting A. mangium in plantations Indonesia. The aim this study was to identify these and investigate their ability cause disease on two plantation-grown using greenhouse field inoculation experiments. For identification, morphological characteristics comparisons DNA sequence data for the ITS, β-tubulin TEF 1-α gene...

Ganoderma root rot is the most serious disease affecting commercially planted Acacia mangium in plantations Indonesia. Numerous spp. have been recorded from diseased trees of this species and to a lesser extent Eucalyptus, causing confusion regarding primary cause disease. In study, large collection isolates were obtained roots A. showing early signs centres South Sumatra plantations. Isolates also collected Eucalyptus at Lake Toba North similar symptoms as well sporocarps connected these...

Summary The rapid emergence of A cacia mangium as the key industrial plantation species in I ndonesia has been followed by equally red root rot ( G anoderma philippii ) its potential nemesis. As a consequence, and on severely affected mineral soils equatorial tropical environments particular, . may no longer be capable producing commercial yields after three rotations. In this experiment, 100‐tree plots were established plantings at five sites which represented range growing conditions used...

Pruning (singling) is a common silvicultural practice in commercial Acacia plantations because these trees tend to have multiple stems. The wounds resulting from pruning are susceptible infection by pathogens. Ceratocystis acaciivora and Lasiodiplodia theobromae been shown recently be important pathogens of A. mangium Indonesia, where they commonly associated with on trees. aim this study was determine the impact different wound types crassicarpa two Isolates C. L. theobromae, found most...

Abstract. The objective of this study is to detect flooded area in rice paddy fields Indonesia by using remotely sensed data. We used synthetic aperture radar (SAR) data for purpose, because it capable getting high-resolution almost all-weather conditions. paper gives a result detecting occurred our research sites located close Bandung area, Tegalluar Bojongsoang district, from the end February beginning March 2018. C-band SAR acquired Sentinel-1 were analysis. derived gamma-naught threshold...

Kondisi fisik optimal ternak dapat dicapai bila didukung oleh kesesuaian lingkungan tempat tumbuh dan kecukupan hijauan sebagai makanan ternak. Analisis dalam penelitian ini dilakukan menggunakan Sistem Informasi Geografis (SIG) pada berbagai peta digital (peta pengunaan lahan, suhu, tanah, elevasi, curah hujan) data- data tabular untuk menilai lingkungan, daya dukung Luas sapi potong di Kabupaten Cianjur yang digembalakan adalah 193,282 hektar (ha) (53.45% dari total luas wilayah),...

Bencana longsor merupakan salah satu bencana yang sering melanda Indonesia. Data dihimpun dari BPBD Kota Bogor, menunjukkan pula bahwa kejadian menempati urutan pertama 6 jenis ada di Bogor; pada tahun 2017 terdapat 179 (40.5%) 442 tercatat. Guna mendukung program pembangunan kota ini, penelitian risiko sangat diperlukan. Penelitian ini bertujuan untuk menilai dan memetakan Bogor merumuskan rekomendasi mitigasinya. Metode digunakan adalah Multi Criteria Evaluation dimana bobot skor setiap...

Lahar merupakan proses alami, namun menjadi berbahaya jika memberikan dampak bagi manusia dan lingkungan. yang terjadi karena hujan dengan intensitas tinggi membentuk aliran bahaya sekunder gunung api. Gunungapi Sinabung meletus pada tahun 2010 hingga saat ini telah mengeluarkan material piroklastik lebih dari seratus juta kubik siap lahar. Untuk mengantisipasi lahar, perlu diketahui pola di sekitar Sinabung. Informasi dapat digunakan untuk menyusun rencana mitigasi menghadapi lahar Analisis...

The flood-detection accuracy verified visible near-infrared images acquired proposed showed VV...

Abstract Since its first introduction to the Indonesian forest plantations, eucalyptus has been associated with pests and diseases. As a component of integrated disease management, some biocontrol agents have developed manage Application endophytic Trichoderma is critical option in this effort; it demonstrated other pathosystems that fungus can improve seedling growth health. This study aims screen evaluate effect isolates on health E. pellita seedlings. Field isolation resulted 43 isolates....
