Abstract

Immunization is the process of making a person immune or resistant to an infectious disease. Overall, Universal Child Immunization (ICU) states that Indonesia has the fourth highest prevalence in the world. Immunization has been proven to be one of the most important public health efforts. Through immunization, it can show great success because it is an effort to prevent infectious diseases. Immunization is influenced by several factors, including the mother's age, level of education, employment, number of children and family support. This research is a descriptive analytical study with a cross sectional approach which aims to see the relationship between family support and children's basic immunization status. The sample in this study was 84 children selected using a cluster random sampling technique with bivariate and univariate analysis using the chisquare test. Data were collected using a family support questionnaire and immunization completeness status. The results of the research show that there is a relationship between family support and basic immunization status for children in the Totoli health center working area with a p value of: 0.000.

Abstract

Seiring kemajuan teknologi, semakin meningkatlah kepentingan computer vision. Hal ini paling jelas penerapannya dalam sistem pengawasan dan keamanan. Teknologi ini akan memungkinkan komputer mengenali dan mendeteksi sebagian besar objek secara otomatis, menggantikan sejumlah besar orang dalam pekerjaan pengawasan. Tujuan penelitian ini adalah untuk mengembangkan sistem kamera otomatis. Sistem ini menggunakan beberapa sensor ultrasonik HC-SR04 dan motor servo untuk mendeteksi pergerakan objek secara real time. Metode sistem ini adalah dengan mendeteksi jarak objek dengan menggunakan sensor ultrasonik, lalu data tersebut diolah oleh mikrokontroler yang nantinya digunakan untuk menggerakkan motor servo. Sehingga kamera pada awalnya dapat menetapkan posisi dimana objek berada, sesudahnya kamera akan bergerak mengikuti objek tersebut. Dengan begitu, kamera dapat menetapkan fokus pada objek tanpa harus diatur oleh operator, karena semuanya berjalan secara otomatis. Hasil penelitian membuktikan bahwa sistem ini dapat bekerja sesuai dengan tujuan dan dapat melacak dengan akurat sehingga luas pemantauan menjadi lebih efektif. Sistem ini dapat diterapkan dalam banyak bidang seperti keamanan rumah, pengawasan kantor, pemantauan mesin produksi, dan lain-lain. Penentuan pergerakan kamera sangat tergantung dari ketepatan sensor ultrasonik membaca posisi objek. Penentuan posisi objek yang bergerak dapat di tentukan dari penempatan beberapa sensor ultrasonik yang diletakkan dengan sudut yang berbeda-beda
