THE EFFECT OF USING IMPROMPTU SPEECH TECHNIQUE TOWARD STUDENTSā SPEAKING ABILITY AT THE SECOND YEAR OF STATE SENIOR HIGH SCHOOL 12 PEKANBARU
Based on school based curriculum (KTSP), speaking is one of skills in
mastering English that must be taught and learned in senior high school. SMAN 12
Pekanbaru is one of schools that uses it as a guide in teaching learning process. After
doing preliminary observation at SMAN 12 Pekanbaru, some of the students of the
second year still have low ability in their speaking. The researcher interpret that they
have low ability in speaking were indicated because they have lack of self confidence
in expressing their ideas in English. Thus, the researcher interested to conduct the
research entitle The Effect of Using Impromptu Speech Technique toward Studentsā
Speaking Ability at the Second Year of SMAN 12 Pekanbaru
The type of the research was quasi-experimental research. The main focus of
this research was to find out a significant difference of improvement of studentsā
speaking ability at the second year of SMAN 12 Pekanbaru between students who were
taught by using impromptu speech technique and who were taught by using natural
approach as the conventional way. The subject of this research was the second year
students of SMAN 12 Pekanbaru. In this research, the researcher took six classes;
experimental and control class from the nine classes. It meant that 91 students as the
sample from 334 students of population by using clustering sample randomly based on
group. In collecting the data, the researcher used test and observation list. The test used
was oral presentation test. In analyzing the data, the researcher used SPSS16.
Finally, the research found that the significant number was 0.000<0.05, and
the implementation of Impromptu Speech Technique well done (95.83%). It means that
there were still any missing item procedures. Based on the significance result above, Ha
is accepted and Ho is rejected. Besides, it can be proved from mean score of studentsā
speaking ability of post-test at experimental class was 61.40, while studentsā speaking
ability of post-test at control class was 51.20. Furthermore, the mean score
improvement of studentsā speaking at experimental class was 12.61 (26.75%) while in
control class only 2.90 (7%). In conclusion, there is a significance difference of
improvement of studentsā speaking ability between students who were taught by using
impromptu speech technique and who were taught by using conventional way; natural
approach so, the difference on mean indicate that the use of impromptu speech
technique is better than natural approach

Effect Of Heat Treatment On Cellulose Crystallinity Of Empty Fruit Bunch Oil Palm Fiber And Its Relation To The Dimensional Stability Of Medium Density Fiberboard
Oil Palm (Elaeis guinensis) is an important commercial agriculture plant in Malaysia generating a vast amount of residues, in the form of oil palm trunk (OPT), oil palm frond (OPF) and empty fruit bunch (EFB) which have high potential as raw material in wood-based industry. However, these lignocellulosic materials have poor dimensional stability i.e., high thickness swelling and water absorption. Cellulose crystallinity has been reported to influence the physical properties of the fibers. This study attempts to increase the cellulose crystallinity of oil palm EFB fiber via heat treatment and aimed i) to evaluate the effect of heating temperature on the cellulose crystallinity of oil pal EFB fiber ii) to determine the effect of cellulose crystallinity on thickness swelling (TS) and water absorption (WA) of Medium Density Fiberboard (MDF) made from heat treated oil palm fibers and iii) to establish relationship between cellulose crystallinity and TS and WA.Oil palm EFB fibers were heated for two hours at different temperatures, 150Ā°C 160Ā°C, 170Ā°C, and 180Ā°C. Untreated samples were used as control. The crystallinity and crystallite size of the cellulose molecules were investigated using X-ray diffraction (XRD) technique. Chemical analyses were also conducted on both heat treated and untreated EFB fibers to determine the proximate amount of lignin, cellulose and hemicellulose. MDF with the size of 130mm x 130mm x 5mm were produced from these fibers. The density of the MDF was 700 Kgm-3. The effects of cellulose crystallinity to the TS and WA of board were examined.
The proximate amount of chemical components in the EFB fiber in this study was found comparable with those of conventional wood. The lignin content was in the range of 20-27%, cellulose content was 40-47% and hemicellulose content was 23-25%.
The results shows that crystallinity of oil palm EFB cellulose were 21.05% for untreated fiber, 27.09% for fiber heated at 150Ā°C, 26.68% at 160Ā°C, 26.53% at 170oC and 30.84% at 180oC. The corresponding crystallite sizes of the cellulose sample were 3.22 nm, 3.42 nm, 3.64, 3.38 nm and 2.93 nm respectively. Heat treatment was found to increase the cellulose crystallinity of EFB fiber but did not markedly affected the crystallite size.
In this study, MDF made from heat treated EFB of oil palm fiber was found to have relatively high TS and WA and failed to pass the Japanese Industrial Standard (JIS A 5906 ā 1983). The TS were 15.9% in the MDF from untreated fiber,16.5% for the MDF from fiber heated at 150Ā°C,16.3% at 160Ā°C, 15.3% at 170Ā°C and 15.6% at 180Ā°C. Meanwhile the WA of the MDF boards was 77.7%, 81.0%, 79.5%, 83.2% and 71.8%, respectively. It was found that the increase in temperature in this study gave no effect to the TS but reduce the WA only at temperature of 180Ā°C. This study found that there were no trend found in the relatioship between cellulose crystallinity with TS and WA at various temperatures as the R-squares were very small. There was also no direct effect of increase in cellulose crystallinity to the TS and WA of MDF as the R-squares were very small.
Even though the cellulose crystallinity of EFB fiber increased by heat treatment, it was not sufficient to impart dimensional stability to the MDF board
STRATEGI COPING REMAJA KORBAN PERKOSAAN
Coping adalah suatu proses dimana individu berusaha untuk āmanageā ketidak sesuaian yang dirasakan antara tuntutan dan sumber daya yang dimiliki dalam situasi yang menimbulkan stres (Sarafino, 1994:139). Untuk mengatasi dampak perkosaan baik secara fisik, seksual dan psikis remaja dapat melakukan upaya yang disebut dengan strategi mengatasi masalah atau disebut dengan istilah coping. Penelitian ini mengacu pada The Cope Scale yang dikemukakan oleh Carver karena lebih rinci sehingga diharapkan dapat memperoleh bentuk perilaku coping yang lebih spesifik. Tujuan penelitian ini untuk mengetahui perilaku coping remaja korban perkosaan.

PENGARUH MEDIA DAKON MATEMATIKA TERHADAP HASIL BELAJAR MATEMATIKA SISWA MATERI PENJUMLAHAN
Islamic Elementary School Students/Elementary school Students need concrete objects in learning process, especially in learning mathematics. An interesting learning media makes students easy in understanding materials. However, there are many teachers still use conventional and traditional media such as textbooks. Teachers should modified the media to suit the this modern era. This study aims to determine the learning outcome of the first-grade students in MIN 3 Tapin using Dakon mathematics media. This study uses quantitative approach and a one group pretest-posttest design. The population in this study were all students in MIN 3 Tapin by total 184 people and the sample was the first-grade students in MIN 3 Tapin. Data collection techniques using test, interviews and documentation. Data analysis technique using t-test. The result shows that there as a significant influence between Dakon mathematics media and students learning outcomes. This is evidenced by the result of the t-test, namely t-count was 1,46 and t-table was 2,306. Itās found that t-count was 11,46 >t-table was 2,306 or t-count higher than t-table, its meant that H0 was rejected and H1 was accepted
