The Indonesian Law No. 14 Year 2005 on teacher and lecturer and Government Regulation No 74 Year 2008 on teacher, have mandated the government to carry out certiﬁ cation for teachers of all subjects who have met the requirements. Based on a survey conducted by the Directorate General of Quality Improvement of Teachers and Education Personnel (PMPTK) in 2009, the certiﬁ cation program has not been able to improve the competence and professionalism of teachers signiﬁ cantly so it has not given positive inﬂ uence on improving the performance of teachers. The purpose of this study is to determine the effectiveness of the model of professional competence improvement of biology teacher based on initial competence test in Surakarta.This research uses R D approach developed by Borg and Gall (2007), which includes six procedures or stages of development: (1) determine the product; (2) conduct a theoretical and empirical study; (3) development planning; (4) the development of early models; (5) validation of the model; and (6) the discovery of the ﬁ nal product. The ﬁ rst up to the fourth stage has been done in previous studies, and this research is the ﬁ fth stage namely the stage of model validation through limited experiment with one-group pretest-Posttest Design. While the data analysis uses traditional descriptive quantitative approach.The results of the study on the effectiveness of implementation of the model of increasing Biology teacher competence based on CPD on a limited scale test show that the classical absorption of pretest is 27.78%, while the classical absorption of post-test is 72.22%. It means that Biology teacher competence based on CPD has increased in a limited test scale of 44.44%. The results of a statistical analysis of the increase of pre- test and post-test absorption on each competence shows that the greatest increase of percentage in absorption was on the competence: “understanding the concepts, laws, and theories of biology and ﬂ exible implementation” for 38.89%. While the lowest increase of percentage in the absorption occurred on the competence: “conducting action research to increase professionalism” with only 13.27%.

Production optimization in mature field water drive gas reservoir is not easy especially when water already breakthrough in producing wells. An integrated reservoir study is needed to get reliable strategy to optimize production of water drive gas reservoir. This research presents the integrated reservoir study of Lower Menggala (LM) Gas Field which is located Central Sumatera Basin, Riau Province. LM had been produced since 1997, current RF are 55%, which is quite high for water drive gas reservoir. The current gas rate production is about 1.97 MMscfd with high water production around 4250 BWPD, consequently some of wells suffered liquid loading problem This research comprises of well performance analysis, estimate OGIP, aquifer strength of the reservoir by using conventional material balance method and modern production analysis method then conduct dynamic reservoir simulation to identify the best strategy to optimize gas production. Economic analysis also be performed to guide in making decision which scenario will be selected. DST analysis on DC-01 well defined reservoir parameter, boundary and deliverability which are P*= 2520 psia, k= 229 mD, Total skin= 8, detected sealing fault with distance 175 m, and AOF 45 MMscfd. Conventional material balance method gave OGIP 22.7 BScf, aquifer strength 34 B/D/Psi, whereas modern production analysis estimated OGIP 22.35 BScf, aquifer strength 34 B/D/psi. Those two method shows good consistency with OGIP volumetric calculation with discrepancy OGIP value +/- 1%. Six (6) scenario of production optimization has been analyzed, the result shows that work over in two wells and drilling of 1 infill well (case 6) achieve gas recovery factor up to 75.2%, minimal water production and attractive economic result

Feed broiler is one important factor that is very supportive of other factors when broiler maintenance. One way to reduce the use of maize is to use alternative raw materials of wheat. Wheat can be obtained and the price is cheaper than corn but contains a high Non Starch Polysaccharide, while the poultry digestive tool is not able to digest such crude fiber because it has no crude fiber-breaking enzymes so it needs enzyme addition to the efficient use of nutrient feed. The research method used is the experimental method using Completely Randomized Design consisting of 4 treatments 5 replications. The treatment is as follows P0 (without wheat and xylanase); P1 (substitution of maize with 20% wheat); P2 (maize substitution with 40% wheat) and P3 (substitution of maize with 60% wheat). The observed variables are metabolic energy of pseudo-feed and metabolically correlated false energy n. Data were analyzed by analysis of variance (ANOVA) if there are differences among the treatments followed by Duncan's Test. The results showed that the use of wheat with a xylanase enzyme supplementation as a substitute corn provides highly significant effect (P<0.01) on the apparent metabolize energy of feed and apparent metabolize energy corrected N. The addition of xylanase enzymes in feed with the substitution of wheat by 20 percent produce the best feed metabolizable energy among other treatments.

This research was arranged using Completely Randomized Design (RAL) with factorial pattern. The first factor is the length of meat immersion in bay leaf solution, namely: P0: control; P1 (20 minutes); P2 (40 minutes); P3 (60 minutes). While the second factor is a piece of carcass, namely: K1 (thigh) and K2 (chest). Each treatment was repeated 3 times. The research variables were pH of meat, WHC, and cooking loss. The data obtained were proceed to variance analyze and further tested by BNT Test for length of immersion and Tukey test for carcass type at 5% level of significant. The results showed that there was no interaction (P>0,05) between soaking time and carcass cut. The duration of immersion had no significant (P>0,05) effect on pH, WHC, and cooking loss. Carcasses cut of thight and breast have a significant effect (P<0,05) on pH and cooking loss, but are not significant (P>0,05) for WHC. The pH value of the thigh meat is significantly (P<0,5) higher than the breast, but the cooking loss is lower. Keywords : Bay Leaf, Breast, Thight, Broiler, Physical Quality
