| Abstraksi Narasi | : | The objective of the experiment was to know the concentration of IAA and BAP that could induce effectively shoot formation on melinjo shoot tip planted on MS (Murashige-Skoog) medium. The shoot tip explants were picked from a hermaphrodite melinjo tree. After sterilization, they were planted on MS medium. Treatment combination of 0.1, 0.3, and 0.5 mg/l and IAA 1, 3, 5, 7, and 9 mg/l BAP were arranged factorially, and aplied into MS medium. The experiment used a randomized complete design with three replications. Culture was placed in culture room under temperature of 25-26 C, 3000 lux light intensity, and 12 hours daylight each day. Results showed that the combinations of 0.1 mg/l IAA and 7 mg/l BAP in MS medium effectively induced shoot formation of melinjo. |

| Abstraksi Narasi | : | The second Liapuno method is used to know both linear and nonlinear differential equations. The aims of the research was to study sufficient condition of stability and instability of a critical point automous system. It was concluded that sufficient condition of stability of a critical point for automous system dx/dt=F(x,y), dy/dt=G(x,y) are (i) automous system has an isolated critical point at the origin; (ii) V continue; (iii) V` exits, continue and positive definite; (iv) V`(x,y) negative semidefinite. While sufficient condition of instability an isolated critical point at the origin for automous system dx/dt=F(x,y), dy/dt=G(x,y) are (i) autonomous system has an isolated critical point at the origin; (ii) V continue;(iii) V` exis and continue; (iv) |

| Abstraksi Narasi | : | The development of the nonparametrics regression have been discussed for a long time due to the limitedness of the parametric regression. The paper will be discusse the kernel method of smoothing Nadaraya-Watson to estimate the relationship between two variables as an alternative method if the parametric regression is imposible to be used. |

| Abstraksi Narasi | : | The have been synthesized the derivatives compound of piperic acid. These compounds are 1-piperilpyperazine, 1-piperilpyrolidine, and 4-piperilmorpholine. Ammonolysis of piperil chloride using pyperazine resulted in about 85% of 1-piperilpyperazine, with melting point 243-244C, using pyrolidine yielded 1-piperilpyrolidine about 82,25%, melting point 123-124C, and with morpholine yielded 1-piperilmorpholine about 51,92%, melting point 147,3C. Rf value these compounds were measured using thin layer chromatography. In addition their ultraviolet and infrared spectrums were detected. |

| Abstraksi Narasi | : | The purpose of the research was to determine the level of aerial CO concentration in the work place of the traffic police, and the concentration level of CO and its influential factors in the police blood in Ujung Pandang municipality. Measurement of CO in the work place of the traffic police was done by detector gas while microdiffusion method was used to measure CO in the police blood. Interview was elaborated to obtain data of health history, smoking habits, complains, expectations, age, and length of service. The results showed that the average CO level in the work place of the traffic police was 4,400 pmm and SD 0,632. This value was lower than the Treshold Limited Value (TLV) namely 20,000 ppm. The average CO in the police blood was 7,791% COHb with SD 3,781. This value was lower close to TLV, namely 10% COHb. Meanwhile, there were 40% of the police who had CO concentration level in their blood higher than TLV. These police suffered from headache, fatigue and hot tempered. |

| Abstraksi Narasi | : | A material microinjection technique has been evaluated and developed to transforn DNA Plasmid to Wasp C. sonorensis. Female wasps were injected by DNA plasmid (pJKP2) at posterior segment of abdoment beside the ovipositor. Transformation was confirmed by Betta-galactosidase assay and Polymerase Chain Reaction. This maternal injection method has relatively high levels of survivals. All injected wasps and their first generation of DNA pJKP2 displayed the positive result after 3 hours assay. The PCR reaction also showed the positive reaction for pJKP2 using primers mH022 and mH027 (568bp). |

| Abstraksi Narasi | : | The hand dermatoglypic research was carried out on thalassemia sufferers who routimly under medical treatmen in thalassemia centre of FKUI-RSCM Jakarta. The objective of the research was to know the difference between the thalassemia sufferers showing alergic reactions toward "constituents" of their transfusion blood plasma (ra) and those child thalassemia sufferers not showing alergic reaction toward "contituents" of their transfusion blood plasma (tra). The observed dermatoglyphic aspects were frekwensi of pattern of the ten finger tips; frekwensi of pattern type of ulna and non ulna on finger I; index of Dankmeijer (ID); index of Furuhata (IF); index of pattern intensity (IP); index total finger count; and corner average of atd. The result of the research shows that frequency of pattern of the ten finger tips statistically was not significant either on male and female (ra). The frequency of pattern type between ulna and non ulna on finger I (left ang right) was significantly different. ID on female (pra) was lower than (ptra), but on mole (Ira) was higher than (Itra). IF on female (pra) was lower than (ptra), also on male. IP on female (pra) was lower than (ptra), but on male (Ira) was higher than (Itra). In conclusion child of thalassemia sufferers with hand dermatoglyphic of ulna on finger I pattern type, low index of Furuhata would be greater showing the risk of alergy reaction toward "constituents" of their blood plasm transfusion. |

| Abstraksi Narasi | : | Biosorption of zinc from solution was studied using Saccharomyces cerevisiae that was cultured under laboratory condition. Several variables affecting the degree of zinc concentration, and initial pH of the solution Concentration of zinc was determined by atomic absorption spectrometry (AAS). The loading of zinc on the biomass was determined as the difference between the initial and final zinc concentration in the solution. The initial solution pH had a dramatic effect on zinc uptake by S. cerevisiae. Zinc uptake increased as the pH was raised from pH 3 to 7. The biosorption of zinc was found to increase linearly as function of initial zinc concentration up to 50 mg/l. The maximum biosorption capacity of S. cerevisiae was calculated using Langmuir isotherm model and was found to be 19.12 mg per gram dry biomass. |
