Ketahanan Lima Jenis Kayu Asal Ciamis Terhadap Sebelas Strain Jamur Pelapuk

Abstract

Fungal resistance of five wood species from Ciamis: tangkalakHassk cangkring Lour kayu putih Powell ki tanah D.C and huru leueur Blume. was observed using Kolle-flask method. Wood samples of inner and outer parts of the log were prepared from three trees of every species. Wood samples were tested against eleven strain of decaying fungi. The results show that tangkalak and ki tanah woods are classified as resistant (class II), while cangkring, kayu putih and huru leueur woods fall into not-resistant (class IV). In general, the weight loss of samples taken from outer part is greater than those taken from inner part of the logs. It indicates that wood samples taken from outer part (not resistant, class IV) is less resistance than the inner part (moderately resistant, class III). There were also resistant variations between trees. In those five wood species, for example, the first tree (P-I) belongs to class III, however the second and third tree (P-II and P-III) falls in to class IV. The highest weight loss was recorded in the inner part log of tree P-I of cangkring, which was exposed into HHBI-324. The wood fungus decaying capability from the highest to the lowest are HHBI-324 HHBI-348 sp. HHBI-209 sp sp. sp. and .

Basic Properties and Potential Uses of Saling-Saling Wood

“…Dalam dunia perdagangan, kayu kurang dikenal dan kurang dimanfaatkan yang berasal dari berbagai wilayah dan umumnya telah menjadi andalan setempat, berpotensi menggantikan kayu perdagangan yang telah langka (Sumarni et al, 2009). Agar peran sebagai kayu pengganti tersebut terpenuhi maka perlu diidentifikasi sifat dasarnya dan kegunaannya (Suprapti dan Djarwanto, 2014).…”

Ketahanan Lima Jenis Kayu Terhadap Serangan Delapan Jenis Jamur Pelapuk

“…Contoh uji berukuran 5 cm x 2,5 cm x 1,5 cm, panjang 5 cm searah serat dibuat dari kayu papan terlebar dari dolok kayu kemudian diserut sehingga tebalnya 2,5 cm, mengikuti pola yang telah ditetapkan dari penelitian terdahulu (Djarwanto, Suprapti & Hutapea, 2018;Suprapti & Djarwanto, 2014). Contoh uji yang digunakan dalam penelitian sifat ketahanan kayu diambil dari bagian tepi (gubal), dan bagian dalam (teras), yaitu lapisan terdekat dengan titik tengah dolok, sedangkan untuk sifat pengkaratan kayu terhadap logam, contoh uji diambil dari bagian teras yakni 4 cm dari titik tengah.…”

A Review on the Potency of Melaleuca leucadendron Leaves Solid Waste in Wood Preservation and Its In Silico Prediction upon Biological Activities

“…Suprapti and Djarwanto successfully identified some fungi attacked to cajuput including Pycnoporus sanguineus, Polyporus, Trametes, Schizophyllum commune, Chaetomium globosum, Marasmius, and Dacryopinax spathularia. Pycnoporus sanguineus is known to be the strongest attacker among them, followed by the genus of Polyporus [79]. Fortunately, although being attacked by fungi, the chemical composition especially the essential oils can block it.…”
