<![CDATA[Noise can affected human health. Industrial noise with high intensity and prolonged exposuretincreases the risk of hypertension. The noise level in the sand and rock mining area PT. X was measured 88.3 dB(A). This studytaimed to analyzedtthe associationtbetweentthe intensity oftnoise andtblood pressuretin sand and rock mining workers PT. X Rowosari, Semarang. Thistwas antobservational researchtwith crosstsectionaltdesign, totaltsample was 31tpeople. This research was conducted at subdistrict Rowosari, Semarang City with research instrument as a questionnaire to interview personal characteristic, sound level meter to measure noise and digital sphygmomanometer to measure blood pressure before and after work. Datatweretanalyzed usingtChi Squarettest at α = 5%. Thetresults showedtthat 18 people (58.1%) had increasedtsystolictblood pressuretand 19tpeople (61,8%) had increasedtdiastolictbloodtpressure. There was an associationtbetween noisetintensity andtsystolic bloodtpressure (p = 0.017; RP = 3.273; 95% CI = 0.93-11.4). There were no associationtbetween noisetintensity andtdiastolic bloodtpressure (p =t0.253; RPt= 1.534; 95%tCI =t0.70-3.36). There were no association between working period and systolic blood pressure (p = 0.972, RP = 1,135, 95% CI = 0.6-2.11) and diastolic blood pressure (p = 0.252; RP = 0.650; 95% CI = 0.37- 1.12). There was no association between prolonged exposure with systolic blood pressure (p = 0.701, RP = 1.238, 95% CI = 0.61-2.50) and diastolictblood pressure (p = 0.697; RP = 0.816; 95% CI = 0.47- 1.41). The conclusion of this study, there is antassociation betweentnoise intensitytand systolic bloodtpressure on sandtand rock mining workers at PT. X Rowosari, Semarang.]]>
