Objectives: The study assesses periapical radiograph image with various android based analysis method to detect granuloma. Materials and Methods: The study uses survey descriptive cross sectional by using questionnaire. The questionnaire is distributed to 70 random respondents. The methods of the android application used are BLOB (Binary Large Object), DCT and LDA (Discrete Cosine Transform and Linier Discriminant Analysis), DWT and PCA (Discrete Wavelet Transform & Principal Component Analysis), and multiwavelet transformation. The questionnaire assessment included accuracy, effectiveness, attractiveness, innovativeness of the android application. Results: Android application with BLOB has effectivity and accuracy of 62,5%, attractiveness and innovativeness of 75%. Android application with DCT and LDA has effectivity and accuracy of 50 %, attractiveness of 70% and innovativeness of 80%. Android application with DWT and PCA has effectivity of 50%, accuracy of 60%, attractiveness of 66,66% and innovativeness of 80%. Android application with multiwavelet transformation has effectivity and accuracy of 50%, attractiveness of 55% and innovativeness of 73%. Conclusion: Based on assessment, the four methods used to detect granuloma are effective and applicative with android-based application. Android-based Application can detect granuloma with approximately more than 70% successful rate. These methods ease the practitioner to interpret the granuloma image.
Introduction: Selasih is one of tropical and subtropical plant used as traditional medicine. It has antibacterial activity especially toward Gram-positive bacteria because it contains volatile oils, tannin, flavonoid and tertepenoid. Method: The study was performed as an experimental laboratory study used Kirby Bauer agar diffusion applied to eight samples of Streptococcus sanguis which was done by twice repetition for each sample. The concentrations of ethanol extract were 16%, 8%, 4%, 2% and 1%.The result was analysed using ANOVA method for single factor of experimental design. The result of the study showed that there was evidence of the antibacterial effect contained in the ethanol extract of selasih leaves inhibiting the growth of Streptococcus sanguis . The average of inhibitory zone for each concentration in every sample, were: 5,25 mm for 16%, 3,22 mm for 8%, 1,84 mm for 4%, 1,53 mm for 2% and 0,19 mm for 1%. The conclusion of the study indicates that there is an antibacterial effects in ethanol extract of selasih leaves (Ocimum basilicum Linn) which inhibits the growth of Streptococcus sanguis. This antibacterial strength is caused by the active content of selasih leaves extract.Conclusion: The extract of basilicum ethanol (Ocimum basilicum L) effectively inhibits the growth of Streptococcus sanguis.
Pengenalan dini antioksidan dan radon merupakan langkah dalam promosi kesehatan guna untuk meningkatkan pengetahuan, sikap, dan tindakan individu karena dapat berdampak pada kualitas hidup. Kegiatan ini dengan metode penyuluhan berprinsip edutaiment dan dibagikan kuesioner sebelum dan sesudah penyuluhan kepada siswa SDN Arjasari kelas IV,V dan VI yang direncanakan di bulan Juli 2017 dan di laksanakan pada bulan November 2017. Data yang diperoleh dari kuesioner dilakukan analisis statistika SPSS t-Test. Pengelompokan responden berdasarkan tingkat pengetahuan yang dimiliki menjadi 3 kategori responden berpengetahuan tinggi, sedang, dan rendah hasil respon siswa terhadap antioksidan dan radon sangat baik. Hal ini terlihat dari peningkatan pengetahuan pengetahuan siswa sebelum dan sesudah dilakukan penyuluhan edutaiment pada kelas IV V dan VI sebesar 2.19% pada kategori rendah, 19,08% pada kategori sedang dan 33,11% pada kategori tinggi. Siswa tertarik dengan dalam radiasi alam dan pengolahan jagung yang dapat menjadi konsumsi dan tambahan penghasilan bagi kedua orang tuanya. Oleh karena itu , perlu dilakukan penelitian lebih lanjut untuk meningkatkan pengetahuan siswa tentang cara meningkatkan kualitas hidup baik secara ekonomi dan sosial yang sesuai dengan Radon Mitigation Program yang di pelopori UNSCEAR dan EPA.
Background; Perception and Radon's awareness has become a public and environmental health problem during this two decade about the dangers and benefits. Food can be used as a free radical preventive agent for radon. Purpose; this study was to discuss the level of knowledge parents of the importance of antioxidants towards radon which has been inspired. This study was conducted on parents of Arjasari Elementary School's students with a total sample of 106 subjects. Method; This studywas used descriptive cross sectional using a questionnaire after counseling. Result; The level of knowledge about food ingredients and sources as a source of antioxidants and perceptions of natural ionizing radiation (radon) showed good at 75.4%, moderate knowledge at 24.6% and no one had bad knowledge .Conclusions; Mostly ,there has
Konsentrasi radondapat mempengaruhi kondisi air yang biasa dikonsumsi masyarakat untuk kebutuhan sehari-hari. Hal ini berpotensi terhadap risiko kesehatan termasuk risiko kanker. Pengamatan potensi ini dilakukan pada sumber-sumber air yang biasa digunakan masyrakat. Sampel didapatkan dari sumber air di berbagai kampung yang biasa digunakan oleh masyarakat sekitar untuk keperluan sehari-hari. Pada penelitian ini sampel di tes menggunakan RAD 7 Electronic Radon detector yang telah disahkan oleh BATAN. Instrument ini digunakan untuk pengukuran radon dalam air, tanah, batuan maupun udara secara komprehensif. Konsentrasi radon pada air bervariasi di setiap sumber air. Konsentrasi radon telah diketahui yaitu 2030± 509 Bq/m 3 yang berasal dari sumber mata air kampung Cisalada dan 1140±393 Bq/m 3 yang berasal dari air sumur Kampung Giri Mulya dan 705±393 Bq/m 3 pada mata air daerah Kampung Pamucatan. Konsentrasi ini digunakan untuk menghitung konsentrasi rerata harian pada penduduk sekitar yang terpapar radon. Dosis rerata harian individu yang terpapar akibat konsumsi air mengandung radon adalah 5,0 × 10 -3 kg/ug/hari dan dosis efektif tahunan lebih rendah dari 0,1 mSv/tahun. Penelitian ini direkomendasikan sebagai acuan komprehensif yang dapat ditarik untuk kajian radiobiologi kesehatan dan toksisitas yang berhubungan dengan penyakit dan kualitas hidup masyarakat.
