Abstract

Woods which have low natural durability are easy to be attacked with wood staining fungi (blue stain) so can decrease its wood quality. Syzygium aromaticum, Melia azedarach and Piper betle contain of active components (botanical fungicide) that can be used as natural preservative to prevent staining fungi attack. The purpose of this research is to know effect of botanical fungicide species and preserved wood investigated, i.e Paraserianthes falcataria and Toona sureni on the attack intensity of wood staining fungi. Results of the research showed that interaction between botanical fungicide and wood species gived very significant effect on the attack intensity of wood staining fungi. The lowest of attack intensity was resulted on Toona sureni that had preserved by Melia azedarach leaf extract. The leaf extract of Syzygium aromaticum, Melia azedarach and Piper betle could keep Paraserianthes falcataria and Toona sureni wood against staining fungi. Toona sureni wood was more resist against wood staining fungi than Paraserianthes falcataria, it was due to higher extractive in Toona sureni than Paraserianthes falcataria. To preserve woods which had bright colour such as Paraserianthes falcataria, more suitable to use Melia azedarach leaf extract which not change wood colour. Key words: Botanical Fungicide, Preservative, Wood Staining Fungi

Abstract

Produksi serasah mangrove berperan penting dalam menyediakan nutrisi esensial bagi lingkungan perairan di sekitarnya, karena memfasilitasi perpindahan bahan organik ke tanah. Produksi serasah merupakan ukuran produktivitas sebagai kontribusi terhadap sistem muara. Hutan Mangrove Baros merupakan kawasan konservasi di sepanjang pesisir pantai Baros dan muara Sungai Opak, yang memiliki keanekaragaman flora dan fauna. Jenis vegetasi yang dominan di sini adalah Avicennia dan Rhizophora. Penelitian ini bertujuan mengetahui produksi serasah jenis mangrove di Pantai Baros. Penelitian dilakukan dengan meletakkan 3 petak ukur pada ke dua  jenis mangrove. Kerapatan pohon setiap petak diukur dan selanjutnya dipasang 3 buah litter trap pada masing-masing  petak ukur yang diletakkan secara purposive. Pengambilan serasah daun mangrove dilakukan setiap 7 hari sekali selama 28 hari. Serasah basah dimasukkan ke dalam plastik  untuk  ditimbang, kemudian dioven pada suhu 85º C sampai beratnya konstan, untuk memperoleh berat keringnya. Pengujian untuk mengetahui perbedaan berat kering serasah daun antar kerapatan  menggunaan uji-t dan uji F. Hasil penelitian menunjukkan kerapatan Avicennia 700 pohon/Ha dan 1.000 pohon/Ha berbeda dalam memproduksi serasah daun yaitu 2.21 gram/m²/hari dan  6,80  gram/m²/hari, sementara kerapatan Rhizophora 500 pohon/Ha, 900 pohon/Ha dan 1.000 pohon/Ha berturut-turut menghasilkan 4,81 gram/m²/hari, 5,21 gram/m²/hari, 7  gram/m²/hari belum menunjukkan perbedaan  dalam memproduksi serasah daun.

Abstract

Anthocephalus cadamba Miq., is a type of tree from South and Southeast Asia which is currently widely cultivated by the community. Jabon has various uses such as block board and particle board. Apart from that, this plant is also known as a fast growing plant. Jabon farmers have their own way of caring for their plants, on of which is plant spacing. The goal of this research was to ascertain the impact of planting distance on survival rate and growth (height and diameter) of 1 year old Jabon plants in Temanggung Regency, Central Java. Data collection was carried out by taking 50 samples in each field consisting of 2x2 m, 3x3 m, and 4x4 m spread across 3 villages in Temanggung Regency. The replicates used were individual Jabon plants. Data from the research results were analysed using by analysis of variance, and tested further using the LSD test. The research results showed that land with a planting space of 3x3 m had a higher percentage of jabon plants than the land with a planting space of 2x2 m and 4x4 m, namely 71%. Land with a planting space of 2x2 m produce a better average height and diameter of jabon plants than of 3x3 m and 4x4 m, namely 1,39 m for height and 1,97 cm for diameter respectively.

Abstract

Wood preservation is important to increase the service life of species woods which have low natural durability. The absorption of preservative in wood is effected by anatomy, physical and chemical properties of wood and kind of preservative. The purpose of this research is to know effect of wood species, i.e : Paraserianthes falcataria, Shorea spp., Cocos nucifera and Toona sureni, and kind of preservative namely borax (Na2B4O7.5H2O) and terusi (CuSO4) on the absorption, retention and penetration of preservative. Results of this research showed that wood species investigated gived significant effect on the absorption and retention. The highest absorption was resulted on Paraserianthes falcataria and the highest retention was resulted on Cocos nucifera wood. Borax gived higher absorption, retention and penetration than terusi. Paraserianthes falcataria wood tend to easier to absorb preservative than three wood others. Key Words : Preservative, Absorption, Retention, Penetration

Abstract

Bamboo is multipurpose plant widely used for many purposes. One of problem in the utilization of bamboo is dimensional change caused by difference of relative humidity. Hence, to overcome this problem is used dimensional stabilization to decrease shrinkage and increase the quality of bamboo. The purpose of this study is to know the effect of bamboo species and concentration of urea stabilizer against tangential and radial shrinkage, Anti Shrink Efficiency (ASE) and ratio of tangential and radial shrinkage (T/R ratio). The bamboo investigated are Gigantochloa apus and Dendrocalamus asper using bulking method at 20%, 40% and 60% urea concentration. Results of the study showed that interaction between bamboo species and urea consentration was very significant effect against tangential and radial shrinkage and Anti Shrink Efficiency (ASE). G. apus stabilized in 20% urea concentration and D. asper stabilized in 60% urea concentration gived lower shrinkage and high tangential and radial of Anti Shrink Efficiency with criteria of dimensional stability was very successful. G. apus had higher dimensional stability than D. asper. Keywords : Bamboo, Dimensional stabilization, Shrinkage, Anti Shrink Efficiency
