Background and Aims: Temperament is determined as a relatively constant, basic, and innate position that underlies and modifies the expression of activity, emotionality, and sociability among people. The current study aimed to investigate the prediction of dark personality traits and self-destruction based on emotion regulation among adolescent females. Materials and Methods: This correlational study included 250 adolescent females using a cluster sampling method in the academic year of 2018-19 in Shiraz, Iran. The participants were asked to complete Difficulties in Emotion Regulation Scale, Dark Triad Scale, and Chronic Self-Destructiveness Scale. Results: The results of the regression analysis showed that emotion regulation with beta coefficients was able to predict significant and positive dark personality traits (0.25), narcissism (0.49), Machiavellianism (0.39), psychopathy (0.32), sadism (0.35), and self-destructiveness (0.49) (P<0.05). Conclusion: Directly targeted interventions to regulate emotion may be useful in addressing risky behaviors of adolescents with self-destructive and dark personality traits.

The objectives of this research are to investigate whether: (1) students’ achievement of grammar taught by applying inductive approach higher than taught by applying deductive approach, (2) achievement of grammar of visual learning style students higher than achievement of grammar of auditory learning style students, and (3) there is an interaction between instructional approaches and learning styles on the students’ achievement of grammar. The population was students of Grade X of Vocational High School 1 Beringin Deli Serdang. Based on Cluster Sampling technique, two classes were chosen, namely Grades X1 and X3. The data were analyzed using a two-way ANOVA with 2 × 2 factorial design. The result reveals that (1) Students` grammar achievement taught by using inductive instructional approach is higher than that taught by using deductive instructional Approach (81,20 > 72,10), (2) Students with visual learning style have higher achievement in grammar than students with auditory learning style (81,90 > 72) and (3) there is significant interaction between instructional approaches and learning styles on students` achievement of grammar (4.906 > 3.96). Thus, it can be concluded that the application of instructional approaches and learning styles can affect students` achievement in grammar.   Keywords: Grammar; Instructional Approach; Learning Styles

Abstract: Staphylococcus is a cause of infection. Infection can be transmitted from a source by an indirect through fomite. Paper money can act as transmission of infectious agents, money acts as a fomite. Smaller denominations of value have higher contamination. This study aims to analyze differences in contamination bacterial Staphylococcus sp on denomination of paper money Rp.2.000, 5.000, Rp.10,000 and Rp.20.000 that currently shop on Adi Sucipto street town Pontianak. The research method used in this research is in the form of difference and the sample in this research is denomination of paper money curently with sampling technique using cluster sampling. Checkup of Staphylococcus spon denomination of paper money using rinse method. On these result of study, denomination of paper money Rp.2.000 that is contaminated staphylococcus sp is 80%, denomination of paper money Rp.5.000 that is contaminated staphylococcus sp is 70%, denomination of paper money Rp.10.000 and Rp.20.000 that is contaminated staphylococcus sp is 80%. The data from result of study has been obtained were analyzed statistically by using fisher exact test, the result of p (0,477) >α (0,05) which mean as H1 is rejected. So it can be concluded there is no difference of contamination bacteria staphylococcus sp on denominations of paper money rupiah.Abstrak: Staphylococcus merupakan penyebab terjadinya infeksi. Infeksi dapat ditularkan dari suatu sumber dengan mekanisme tidak langsung melalui fomite. Uang kertas dapat bertindak sebagai transmisi agens infeksius ,uang berperan sebagai fomite. Pecahan uang yang lebih kecil nilainya memiliki kontaminasi yang lebih tinggi. Penelitian ini bertujuan untuk menganalisis perbedaan cemaran bakteri Staphylococcus sp pada pecahan uang kertas Rp.2.000, 5.000, Rp.10.000 dan Rp.20.000 yang beredar di warung jalan Adi Sucipto kota Pontianak. Metode penelitian yang digunakan dalam penelitian berbentuk komperatif dan sampel pada penelitian ini adalah pecahan uang kertas rupiah dengan.teknik pengambilan sampel menggunakan purposive sampling. Pemeriksaan Staphylococcus sp pada pecahan uang kertas rupiah menggunakan metode rinse. Pada hasil penelitian pecahan uang kertas Rp.2.000 yang tercemar staphylococcus sp adalah 80%, pecahan uang kertas Rp.5.000 yang tercemar staphylococcus spadalah 70%, pecahan uang kertas Rp.10.000 dan Rp.20.000 yang tercemar staphylococcus spadalah 50%. Berdasarkan data dari hasil penelitian yang telah didapat dianalisis menggunakan uji statistik fisher exact, didapatkan hasil p (0,477) >α (0,05) yang diartikan sebagai H1 ditolak.
