Kebisingan mempengaruhi kesehatan, antara lain dapat menyebabkan kerusakan pada indera pendengaran sampai kepada ketulian. Tujuan penelitian ini yaitu untuk mengetahui pengaruh Intensitas kebisingan terhadap ambang dengar pada pekerja rumah kayu di Kelurahan Wolian I dan II Kota Tomohon.Jenis penelitian ini merupakan studi observasional analitik dengan rancangan cross sectional study. Hasil perhitungan besar sampel dalam penelitian sebesar 34 orang tenaga kerja.Hasil pengolahan dan analisis data secara bivariat dengan menggunakan uji chi square mendapatkan hasil yaitu terdapat hubungan yang bermakna antara kebisingan dengan ambang dengar pekerja rumah kayu, terdapat hubungan yang bermakna antara lama kerja dengan ganguan ambang dengar pekerja rumah kayu, yang memperoleh nilai p = 0,031, tidak terdapat hubungan antara umur responden dengan gangguan ambang dengan pekerja rumah kayu di Kelurahan Woloan I dan II Kota Tomohon, yang memperoleh nilai p = 0,745. Saran, bagi perusahaan pembuatan rumah kayu sebagai bahan masukan agar dapat menyediakan alat pelindung diri berupa tutup/sumbat telinga bagi pekerja sehingga penyakit akibat kerja berupa gangguan pendengaran dapat dihindari
Lead is a metal that is very dangerous and toxic to humans, which can be derived from the act of consuming food, drink or inhalation from the air, dust contaminated with Pb, contact with skin, contact with eyes and through parental. Lead can cause air pollution due to motor vehicle emissions gas. Street vendors are one of the groups that can be exposed to Pb. The purpose of this study was to determine the relationship of lead levels (Pb) in urine to the length of street vendors selling at the 45 markets of Manado City. This research uses observational analytic method with cross sectional design. The sample in this study were all street vendors selling from zero points to the front of jumbo in Pasar 45. Purposive Sampling was carried out by sampling. The results of this study showed that the average length of work was 12 hours, the average lead level in urine for all samples was 0.8461 mg / L which had exceeded the threshold value of 0.15 mg / L. Statistical test results using Pearson Product Moment correlation show there is no significant relationship between work duration and levels of Pb in urine (r = -0.024, p = 0.899). The conclusion of this study is that there is no relationship between lead levels (Pb) in urine with the length of street vendors selling at the 45 markets of Manado City.
The Tondano watershed rehabilitation project is a project that consists of the construction of embankments and roads along the Tondano river. This project activity can cause air pollution, which has the potential to affect the occurrence of public health problems, especially the occurrence of lung capacity disorders. From the results of the preliminary service, it was found that some people complained of frequent coughing, runny nose and shortness of breath. Based on this fact, research was conducted on the effect of dust on the disruption of the lung capacity of the community. This research is a descriptive study. The samples in this study were 26 people. The instrument used to measure lung capacity is a spirometer. The variables studied were Das Tondano Rehabilitation Project Dust levels and Lung Capacity. The results showed that the level of dust in the study area around the Das Tondano rehabilitation project site in Environment 4 of Karame Sub-district was the value of dust content at point I 266 μg / m3, point II 644 μg / m3, point III 488 μg / m3. Average value of 466 µg / m3. above the PP 41/2009 quality standard of 230 μg / m3. From the measurement of lung capacity, the incidence of lung capacity is 4 people (15.4%). In the project initiator to carry out regular ambient air quality monitoring around the Das Tondano rehabilitation project and efforts to control air pollution by carrying out road pollution every day.
