Â The experiment aimed to produce native chicken with faster growth rate that is to achieve body weight of more than 1 kg at 3 months of age. Three hundreds and thirty three crossbreeds (PK) day old chicken from the results of artificial insemination between male Pelung and second generation of selection of female native chicken, were used in this experiment. One hundred and eighty purebreds native chickens were also used as control population. They were put in grower cages with density of 10 birds per cage and each cage was treated as a single unit of replication. Feeds during experiment were given and divided into 3 phases that is Starter Feeds I (Protein 21% and Energy 3000 kcal/kg) for chicken between 0-21 days of age, Starter Feeds II (Protein 19% and Energy 2900 kcal/kg) for chicken between 22-42 days and Grower Feeds (Protein 17% and Energy 2900 kcal/kg) for chicken between 43-84 days. Variables which were recorded were weekly body weight until 12 weeks of age, feed consumption, feed conversion, mortality, carcass weight and simple economic ratio (B/C ratio). The results of the experiment showed that body weight at 12 weeks of crossbred (PK) was significantly higher than the pure native chicken (1000 vs 923 g) (P<0.05). Feed consumption was not significantly different (3037 vs 3036 g/bird/12 weeks), but the feed conversion of the crossbred was significantly better than the purebred (3.09 vs 3.4) (P<0.05). Carcass weight and carcass components were not significantly different between the two breeds, but they were different between sexes (P<0.05). Simple economic calculation showed that crossbreeds produced higher profit than purebreds with the benefit cost ratio were 1.31 for crossbred (PK) and 1.2 for purebred native chicken. The mortality rate during the experiment was low, that is 5.5% for crossbred and 6.36% for purebred. Â Key words: Crossbreeding, male Pelung, female native chicken

An experiment was conducted to evaluate the performance of production traits of the synthetic population of Border Leicester x Merino crossbred. A comparison was made between the F2, F2.5, F3 generations ( synthetic population ) and Fl generation. Estimates the effects of maternal heterosis in the synthetic populations of Border Leicester x Merino crossbred were analyzed by the method of least squares for Birth Weight (BW), Weaning Weight (WW) and Yearling Weight (YW). Two kind of analyses were executed for each traits i.e. within Fl sire generation and within F2 sire generation. For each analysis, maternal heterosis was respectively calculated as twice the difference between the least squares means of F2 and F2.5 lambs and F2.5 and F3 lambs.Pool estimates of maternal heterosis effects were also calculated for each traits. Research results showed that there was no significant difference of BW between F2, F2.5 and F3 generation. Weaning Weight was significantly higher (P < 0,05) in the synthetic population as compared to the Fl generation. Yearling Weight (YW) was significantly higher in the F2 generation as compared to F2.5 and F3 generation at the level of 5% (P < 0,05 ) and the 10% level (P < 0,10 ) respectively. Within Fl sire generation,maternal heterosis effects were 12,65%, 3,4% and 1,67% for Birth Weight (BW), Weaning Weight (WW) and Yearling Weight(YW). From the analysis within F2 sire generation, maternal heterosis effects were 1% for BW, 4,49% for WW and 3,09% for YW.Pool estimates of maternal heterosis effects were 5,78%, 3,95% and 2,37% for BW, WW and YW respectively. These results indicated that the effect of maternal heterosis gradually declined from preweaning to postweaning periods. In general, the present estimates of maternal heterosis for body weights are in close agreement with previous publications.In order to gain maximum benefit from heterosis, these results suggest that in designing a crossbreeding program,especially in developing a new synthetic population, we should take into account not only individual heterosis effects but also all other different sources of heterosis such as maternal heterosis. Genetic methods presented in this paper can be used in the breeding program in Indonesia,especially in the development of the improved synthetic sheep population. However to the determine the superiority of synthetic population over the Fl generation, the overall comparison should be made on body weight, growth rate, survival rate and fertility traits.

In the oil industry, the main challenge is to maintain a stable oil production rate, especially when reservoir pressure decreases. Therefore, artificial lift methods are used to increase production rates. The LX well is one of the wells located in the Tarakan field, North Kalimantan, where at the beginning of production the Artificial Lift method had not been used. This study aims to analyze the production performance and economic aspects of the use of 2 artificial lift methods, namely Progressive Cavity Pump (PCP) and Sucker Rod Pump (SRP). The simulation results show that the flow rate increases with increasing operating speed and number of strokes per minute. The optimal speed for PCP is 400 rpm with a flow rate of 1668.14 STB/d, while for SRP, the optimal SPM is 22 with a flow rate of 1686.89 STB/d. The analysis of the economic calculation of the use of the PCP artificial lift method obtained a POT of 0.69 years. Calculation with DCA method, obtained IRR ranging from 132% - 133% and NPV ranging from $3,499,432 - $3,842,340. Based on the results of economic calculations from the use of the SRP artificial lifting method, the POT is 1 year. Calculation with the DCA method obtained IRR values ranging from 82% - 84% and NPV ranging from $1,661,827 - $2,008,573. These results indicate that this project is financially feasible.
