Abstract

Pseudomonas solanacearum is a bacterial agent causing wilt disease on mulberry species and other woody plant in Indonesian. Biological control employing the antagonist bacteria such as P. fluorescens and P. Putida is a potential method. The aim of the research was to know the effectiveness of P. fluorescens and P. putida to suppress wilt diseases caused by P. solanacearum. The diseases control test with antagonist bacteria was conducted by immersion of root of seedlings in P. fluorescens and P. putida suspensions before planted in a growth medium inoculated by P. solanacearum with the all concentrations were 108 CFU/ml. The following parameters were observed: numbers of leaves, fresh and dry weights of leaves and severity of disease. The results of the effectiveness test showed that antagonist bacteria in the form of mixing of P. fluorescens and P. putida was the best, because they were capable to suppress wilt disease caused by P. solanacearum and increased productivity of mulberry leaves. keywords : antagonist bacteria, biological control, wilt disease

Abstract

Wood deterioration were generally occured by the activities of biological agents. Fungal can attack wood and lignoselulosic substances and cause staining and decaying. Its damage levels were vary depending on the attacking fungal species. Eventhough it poses some disadvantages, actually fungy have potential benefits for human life such as nutrient, energy resources, medicine, etc. Fungy from Tabo-tabo educational forest were collected, isolated,and identified in this study. Identification was conducted throughout their macroscopic and microscopic characteristics. The result showed that the amount of fungal species were nineteen species, i.e: Aspergillus sp.,Poria subacida, Fomes sp., Lenzites sp., Hericium sp., Dacrymyces deliquescens, Ganoderma lucidum, Clitocybe sp., Trametes confragasa, Shizophyllum commune, Periconia sp., dan Helicosporium sp.,Clitocybe sp., Schizophyllum commune, dan Hygrophorus hypotejus,Ganoderma lucidum dan Coprinus atramentarius, Amanitopsis fulva dan Dacrymyces deliquescens, Collybia sp., Amanitopsis fulva, Hygrophorus hypotejus,Coprinus atramentarius, Monilia sitophilia, Gilmaniella sp. dan Conoplea sp.

Abstract

The development of an alternative energy is now becoming important due to the decrease of natural energy source, The current research was conducted to observe the quality of making charcoal briquette from cocoa pod shell with the particle size of 30 mesh, 50 mesh, 70 mesh and 7 % starch as adhesive. The result showed that charcoal particle size of 70 mesh gave the best charcoal briquette quality having characteristics: moisture 10.67 %, density of 1.15 g/cm3, 18.98% ash content, 49.93 % fixed carbon, 24.99% volatile matter and the calorific value of 4372.54 cal/g. Charcoal briquette from cocoa pod shell was utilized as alternative energy. Key words: Cocoa pod shell, charcoal briquette, starch as adhesive. References

Abstract

Kabupaten Gowa has 63.099 ha forest area, consists of 24.226 ha of protected forest, 3.309 ha of conservation forest/recreation forest, and 35.554 ha of production forest. The value of forest resource can be estimated based on use value an non use value. Use value of forest resource in Kabupaten Goewa covers direct economic value wich is obtained from timber product and non timber product. While indirect economic value is obtained from iriigation water, fresh water, agriculture production increase, and forest recreation value and also contribution in labour section. Contribution of agricultural sector in Bruto Regional Domestic Product (Produk Domestik Regional Bruto = PDRB) of Kabupaten Gowa base on the data of 2000 to 2005 is high enough, more than half of PDRB of Kabupaten Gowa which is 52,29 %. However the contribution of subsector of forestry to the economy of Kabupaten Gowa is very small, only 0,17 %. the use of ecpnomy rent for land of rehabilitation in 2005 has been use as much as Rp. 142.384.858,- for 95,50 ha of area. This fund is come from Dana Alokasi Khusus - Dana Reboisasai(DAK-DR)40 % (special allocation fund-reforestration fund 40 %) the part is managed by the region of production.

Abstract

The plant diversity using shanon index and the farmer income level were investigated in this study. This information is very important to contribute some improvement of agroforestry pattern related to the farmer welfare and the ecological productivity in upperstream Minraleng Sub Watershed. Results show that the diversity index of mix public forest was higher than the other patterns, eventhough it has a lower contribution compared to paddyfield. Paddyfield and unirigated-land have a higher contribution to farmer income, but they have lower diversity indexes. In contrast, candlenut monoculture and mix garden have higher diversity indexes and lower contribution to farmer income. A plant diversification under candlenut stands and an economical plant intensification on mix garden were needed to increase the farmer income and the diversity of economic plants. Key words: Diversity index, farmer income, agroforestry, Minraleng Sub Watershed References

Abstract

A research was conducted to evaluate the quality of white refined sugar produced from palm tree (Arenga pinnata) using direct and indirect cooking processes. Visual methods were applied to determine color, shape and texture of produced sugar. The sucrose, ash, and other sugar contents as well as dry weight of produced refined sugar were also analyzed. Results showed that the production process using direct cooking resulted in small granulated, dry, compacted and milky white refined sugar, while that using indirect cooking (four hours storage) produced clay granulated, less compacted, dust shape and browning refined sugar. The sucrose, ash, and other sugar contents found in direct cooking process were 10.27%, 0.016%. and 2.68%, respectively, while those found in indirect cooking process were 11.11%, 0.018%, and 2.78%, respectively. Keywords: Palm tree, Arenga pinnata, nira, white refined sugar
