PERFORMANCES OF VILLAGE CHICKEN FOLLOWING CROSS BREEDING WITH DIFFERENT BREEDS OF CHICKEN
The performances of village chicken in South-east Sulawesi, Indonesia were typically small and light weight, and low productivity of both egg and meat. However, they more resistant to disease compared to other breed of chicken such as commercial broiler or layer. Therefore, in this research the more productive breed of cocks were used. The objective of this research was to improve productivity of the village chicken using different breeds of cock. Bangkok-crossed breed chicken, commercial broiler and village chicken were used to mate the hen of village chicken using artificial insemination. Variables measured were egg fertility, egg hatchability, and day old chick weight of village chicken crossed by different breeds. Duncan multiple range test was applied to compare the averages of each data. The results showed that the higher egg fertility and hatchability were obtained when crossing the hen of village chicken and bangkok-crossed breed cocks, although no statistical differences was showed between breeds of cock. The average of day old chick weight was also higher in a group of village chicken hen crossed by bangkok-crossed breed cocks compare to other breeds, but no significant differences was showed. It was concluded that the bangkok-crossed breed cocks tended to be a good candidate for increasing the productivity of village chicken
THE IMPACT OF THE GOLD MINING ON THE SOCIAL, ECONOMIC, ANDCULTURAL IN THE BOMBANA DISTRICT SOUTHEAST SULAWESI PROVINCE

COMPARATIVE STUDIES ON PHYSICOCHEMICAL PROPERTIES OF THE MINERAL SOILS IN THE MAJOR SAGO-PALM (METROXYLON SAGU ROTTB.)-GROWING AREAS OF EASTERN INDONESIA
Physicochemical properties of the mineral soils, under major sago-palm-growing areas in the eastern Indonesia around Sentani near Jayapura, Papua Province (hereafter Jayapura); Kairatu, Seram Island, Maluku Province (Seram); Kendari, Southeast Sulawesi Province (Kendari); were studied and compared. The soil samples of 0-15 cm and 15-30 cm depth were collected from every site, respectively, from September 2005 to January 2008. The results revealed that the average of physicochemical properties of the soils from 0-30 cm depth in the sago-palm-growing areas varied depending on the site. Soil bulk densities were averagely higher in Seram (1.35 g cm-3) than those in Kendari (0.98 g cm-3) and Jayapura (0.89 g cm-3). Soil textures around Jayapura were dominated by silty loam. While in Seram soil texture was dominated by silty loam and loam, and around Kendari it was dominated by sandy loam, loam and silty clay. The averages of soil pHs were slightly acid (6.4) in Jayapura, acid in both Seram (5.5) and Kendari (4.9). Total carbons (total-C) in Kendari were higher (30.5 g kg-1) than those in Jayapura (27.2 g kg-1) and Seram (9.9 g kg-1). Based on the averages of nutrient contents including the CEC and the total-C, the sago-palm-growing areas showed the same trend in the order of Kendari > Jayapura > Seram in the CEC, total-N and total-C. On the other hand, the exchangeable-K, and the available-P were showed the trend in the order of Jayapura > Seram > Kendari. Variations of soil fertility such as the exchangeable-K, CEC, and total-N among the soils collected sites in each area are higher in the order of Kendari > Jayapura > Seram. And also we tried to discuss about the relation between the soil physicochemical properties and the reported growth parameters or starch productivity of sago palms grown on the same researched areas
