UJI EFEKTIVITAS BAKTERI ANTAGONIS Pseudomonas flourescens DAN P. putida UNTUK MENGENDALIKAN P. solanacearum PENYEBAB PENYAKIT LAYU PADA TANAMAN MURBEI
Get PDFPseudomonas 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.

PEMANFAATAN NIRA AREN (Arenga pinnata Merr) SEBAGAI BAHAN PEMBUATAN GULA PUTIH KRISTAL
Get PDFA 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.

KONTRIBUSI HUTAN PINUS RAKYAT TERHADAP PENDAPATAN MASYARAKAT DI TANA TORAJA
Get PDFA study on the contribution of community forest to the community income in Tana Toraja Regency was implemented with the aim of identifying the community forest contribution to owners income and formulating the effort that can be carried out for enhancing the contribution. As the result, the community forest contribution to owners income is still very low (2.94% in average). Based on analysis result, the potencial revenue of community forest farming in Tana Toraja Regency can be 2.3 larger than the present obtaining revenue. The mentioned potencial revenue can be more increased by developing a more proportional allocation of the revenue to the related farmers (related communities)

PENENTUAN JENIS TUMBUHAN PENCIRI PADA EMPAT KOMUNITAS TUMBUHAN DI KAWASAN KARST MAROS-PANGKEP SULAWESI SELATAN
Get PDFThe study aims to determine the distinguishing plant species within a plant community forest in the karst area of Maros-Pangkep. Plots of 20 meters by 20 meters were purposively established on 40 different locations representing proportionally facies of massif, porous, leyered and metamorphosed carbonate rocks. Tree dimensions in terms of height and diameter of trees in every plot were measured. The data were examinated through table method and principal component analysis (PCA). The study indicated that the distiguishing plant species determined by table method, only could diffrenciate between the group of communities over massif, porous rock facies and the group of communities over layered, metamorphosed rock facies. Whereas, determining plant species characteristic by PCA method gave sharper interpretation about the distiguishing plant species of plant communities among massif, porous, layered and matamorphosed rock facies.
