Abstract

Abstrak. Handphone atau telepon  selular  lebih  dikenal  dengan  nama  ponsel,  saat  ini hampir menjadi  kebutuhan primer  setelah  sandang,  pangan  dan  papan.  Sebagian  besar  penduduk  di  negara  ini  menggunakan ponsel  sebagai  alat  komunikasi,  bahkan  jumlahnya  mengalahkan  persebaran  penggunaan  telepon rumah.`Ponsel adalah  salah  satu  alat  komunikasi nirkabel,  yang memanfaatkan  gelombang  radio sebagai medianya. Keunggulan memanfaatkan gelombang radio ini jika dibandingkan dengan penggunaan  kabel, adalah kemampuannya untuk digunakan secara mobile, dapat digunakan dimana saja asalkan ada sinyal. Selain itu, penggunaan ponsel tidak memerlukan instalasi yang rumit seperti pada pemasangan telepon rumah yang menggunakan kabel. Baeberapa penelitian yang telah dilakukan dibeberapa Negara, seperti yang telah dilakukan pada University of Arizona, menyatakan bahwa ponsel sering dianggap bisa menyebabkan tumor otak karena diyakini bisa mengantarkan gelombang elektromagnetik, walaupun sejujurnya hingga sekarang belum ada bukti yang pasti. Tetapi berdasarkan penelitian terbaru menyebutkan bahwa ponsel yang kita gunakan sehari-hari ternyata memiliki radiasi yang cukup mematikan dalam jangka panjang jika kita tidak berhati-hati dalam menggunakannya pengaruh radiasi radio yang dipancarkan  dari ponsel teranyata berpengaruh terhadakesehatan terutama pada sistem reproduksi.Abstract. Handphones or cellphones which are known as phonecells becoming the primary need for every people. Most of the people in Indonesia use phonecells as a main tool for communication. Eve, the number of phonecells is more significant than the number of the home phones. Mobile phones are one of the wireless communication devices, which utilize radio waves as the medium. Compared to the use of wires, the advantages of using the radio waves are more invisible; which can be used mobile or portable and also can be used everywhere and anywhere as long as it has a signal. In addition to that, the use of cellphones do not require complicated istallation as the homephones. Some studies have been done in several countries. One of the studies  has been done at the University of Arizona. The surprising result was found that the effect of cellphones may cause the brain tumor as it is believed it could  deliver the electromagnetic waves to the brain, but there is no research yet on this fact. Therefore, the recent research  shows the increadible fact where the phonecells has deadly radition. This effect will shown after the long term use of the phonecells. The other effect of the radiation  is also effected on health especially on women reproductive system.

Abstract

The purpose of this study was to determine the effect of providing education on increasing knowledge, attitudes, and behavior of medical officers in solid medical waste management at the Regional General Hospital dr. Zainoel Abidin Banda Aceh, Indonesia. The research design used was a quasi experiment with the Wilcoxon comparison test. The research sample was the medical officer of dr. Zainoel Abidin Banda Aceh as many as 94 people who were divided into treatment and control groups. Knowledge, attitude, and the behavior of medical personnel was measured by interview using a questionnaire. The results showed that there was an effect of educational interventions on increasing the knowledge, attitudes, and behavior of medical personnel in the management of medical solid waste in the treatment and control groups (p <0.05). The results of the Wilcoxon test between the treatment groups on knowledge, attitudes, and behavior before and after the educational intervention showed a significant difference (p = 0.000), whereas in the control group between before and after the educational intervention did not show a difference with the p-value of knowledge (p = 0.102); attitude and behavior (p = 0.157). In the control group, the level of knowledge, attitudes and behavior tends to remain at a sufficient level. The conclusion of this study shows that educational interventions can provide an increase in the knowledge, attitudes and behavior of medical personnel in implementing solid medical waste management at dr. Zainoel Abidin Banda Aceh.
