"ABSTRAKUp to present, plaque control is the most effective method to maintain oral hygiene. Using chewing gum after eating food and snacks can stimulate saliva, promote remineralization and reduce potential dental plaque. To know whether using chewing gum can reduce plaque index as good as toothbrushing, thus an experimental study was performed. Sample was the first grade of junior high school students. After selection according to the requirements, the sample size was 35 students. Each sample got two different treatments. In the first day, they used chewing gum and the next day they were instructed to brush their teeth. Before and after using chewing gum and toothbrushing their dental plaque was scored. The mean of plaque score before using chewing gum was 2.24 and after using chewing gum was 1.28, statistically there was a significant difference (t=33; df=34; p,0.001). The mean of plaque score before toothbrushing was 2.26 and after toothbrushing 1.10, statistically there was a significant difference. Using chewing gum and toothbrushing can reduce plaque score, though the reduction of plaque score by toothbrushing was greater compared with using chewing gum."

"Latar Belakang: Banyak anak menghabiskan waktunya untuk menonton TV lebih lama daripada aktivitas lainnya termasuk untuk belajar. Akhir-akhir ini banyak media visual baru bermunculan seperti internet dan permainan komputer, sehingga waktu yang dihabiskan anak untuk pemanfaatan media visual menjadi lebih banyak. Penelitian yang mempelajari pengaruh media visual terhadap prestasi akademis masih terbatas, terutama di Indonesia. Kebanyakan penelitian yang ada hanya meneliti satu jenis media visual yaitu TV, dan sebagian besar hanya membahas dari segi waktu yang digunakan tanpa memperhatikan segi jenis acara. Tujuan: Mengetahui pola pemanfaatan media visual murid SMPN 115 Jakarta dan hubungannya dengan prestasi akademis, serta faktor apa saja yang memengaruhi prestasi akademis. Metode: Penelitian bersifat potong lintang analitik dengan pengumpulan data menggunakan survei, kuesioner, dan logbook pada bulan Mei hingga Juli 2012. Subjek penelitian adalah 129 murid kelas VII SMPN 115 Jakarta yang dipilih secara consecutive sampling. Analisis statistik dilakukan untuk mencari faktor yang berhubungan dengan prestasi akademis dengan cara uji kai kuadrat (analisis bivariat) dan uji regresi logistik (analisis multivariat). Hasil: Prevalensi murid SMPN 115 Jakarta yang memanfaatkan media visual selama >2 jam per hari adalah 39,5% pada hari kerja dan 64,3% pada hari libur. Prevalensi murid SMPN 115 Jakarta yang memanfaatkan media visual tidak sesuai dengan usianya adalah 69% pada hari kerja dan 63,6% pada hari libur. Lama pemanfaatan jenis acara media visual pada hari kerja maupun hari libur, pendidikan ibu, status pekerjaan ibu, pendapatan per kapita, struktur keluarga, dan pendidikan di luar sekolah tidak memengaruhi prestasi akademis. Faktor yang secara statistik bermakna memengaruhi prestasi akademis murid SMPN 115 Jakarta adalah jenis kelamin (nilai RO 3,264 (IK95% 1,38-7,74; p=0,007)), nilai IQ (nilai RO 4,634 (IK95% 1,66-12,90; p=0,003) untuk perbandingan nilai IQ rata-rata dan superior, nilai RO 5,452 (IK95% 1,51-19,64; p=0,009) untuk perbandingan nilai IQ rata-rata dan sangat superior), motivasi berprestasi dan strategi belajar (nilai RO 4,089 (IK95% 1,14-14,70; p=0,031) untuk perbandingan motivasi rendah dan sedang, nilai RO 61,104 (IK95% 7,42-502,95; p<0,001) untuk perbandingan motivasi rendah dan tinggi), masalah emosi dan perilaku (nilai RO 0,45 (IK95% 0,37-0,54; p=0,01)), serta pola asuh orangtua (nilai RO 0,45 (IK95% 0,37-0,55; p=0,022)). Simpulan: Tidak ada hubungan antara media visual dengan prestasi akademis murid SMPN 115 Jakarta. Faktor yang memengaruhi prestasi akademis murid SMPN 115 Jakarta adalah jenis kelamin, nilai IQ, motivasi berprestasi dan strategi belajar, masalah emosi dan perilaku, serta pola asuh orangtua.

"Penelitian ini dilakukan untuk mengetahui hubungan antara prestasi akademik dan keterlibatan ayah pada remaja Sekolah Menengah Pertama. Prestasi akademik diukur melalui nilai rapor semester I yang diperoleh responden dari sekolah, sedangkan pengukuran keterlibatan ayah dilakukan melalui the Father Involvement Scale (Reported) yang disusun oleh Finley dan Schwartz (2004). Responden pada penelitian ini berjumlah 263 remaja kelas VIII Sekolah Menengah Pertama yang berusia 13 hingga 15 tahun dan memiliki sosok ayah. Hasil penelitian ini menunjukkan bahwa tidak ada hubungan yang signifikan antara prestasi akademik dan keterlibatan ayah pada remaja Sekolah Menengah Pertama (r = -.026; n = 263; p > 0,05, two-tailed). Walau hasil penelitian tidak menunjukkan hubungan yang signifikan antara prestasi akademik dan keterlibatan ayah, namun tidak berarti ayah tidak memiliki peran pada prestasi akademik anak remaja. Di masa tersebut remaja masih memerlukan keterlibatan ayah guna mendukung pencapaian prestasi akademik yang optimal di sekolah.

This study examined the relationship between academic achievement and father involvement among junior high school students. Academic achievement was measured by students’ official school records, whereas the father involvement was measured by the Father Involvement Scale (Reported) (Finley & Schwartz, 2004). The participants of this study were 263 8th grade junior high school students who have a father and encompassing the age between 13 and 15 years old.

The result of this study indicates that there is no significant relationship between academic achievement and father involvement among junior high school students (r = -.026; n = 263; p > 0,05, two-tailed). Furthermore, although the result of the study indicates no significant relationship between father involvement and academic achievement among junior high school students, but it does not mean that father does not have any role at all in student’s academic achievement, because during that period, adolescents still need father involvement in order to support the optimum academic achievement in their school."
