Abstract

Carbon monoxide inhaled into the lungs will enter the blood circulation and inhibit the entry of oxygen needed by the body. This gas combines with hemoglobin to form carboxyhemoglobin (COHb). The increase in COHb in the blood will inhibit the function of oxygen transportation and will affect the health of workers. This study aims to determine the risk factors for increasing COHb in Tirtonadi Bus Station Surakarta officers. The research method used analytic observational with a cross-sectional design. The research population was 110 respondents with a purposive sampling technique to get a research sample of 43 respondents. CO levels in the environment were measured by a CO meter, while COHb levels were measured by a spectrophotometer. The research data were analyzed using Spearman rank. Statistical correlation test showed a significant relationship between CO levels in the environment and COHb levels, p-value = 0.000 and r-value = 0.897, and no significant relationship between length of work and COHb levels with p-value = 0.285 and r-value = - 0.167. CO in the environment is related to the COHb level of traffic security officers at Tirtonadi Bus Station Surakarta, and the length of work is not related to the COHb level of traffic security officers at Tirtonadi Bus Station Surakarta.

Abstract

Industrial noise is generally one of the risk factors for occupational and environmental safety and health. Noise is a risk factor for decreased hearing threshold value in addition to other factors such as age, working period. This study used a cross-sectional design that aimed to identify the hearing threshold level (HTL) of rice mill workers exposed to hazardous noise in Karanganyar Regency, and investigate the relationship with other factors such as age, tenure. Audiometric data from 92 participants were collected through audiometric examination by qualified personnel using an audiometer in a quiet environment. The test was conducted after the participants had rested completely for >14 hours after their last exposure to workplace noise. The results showed that all participants had worked in a noise-hazard work zone for >1 year. The participants' ages ranged from 28 to 57 years. The average hearing threshold in the right ear was 36.71 dB and the average hearing threshold in the left ear was 39.55 dB. The hearing loss associated with work experience was greater than that caused by noise intensity age. Noise intensity, age and working experience were significant to the workers' ear hearing threshold values. Multivariate test results show that noise intensity is the most influential factor (>60%) on HTL. HTL among industrial workers should be assessed regularly. At the health policy level, these workers need to start being protected when they start working.

Abstract

Kota Surakarta sebagai salah satu kota yang terus berkembang, menjadikan pemerintah setempat berupaya untuk memperbaiki infrastruktur dan memenuhi kebutuhan transportasi masyarakat. Revitalisasi Jembatan Jurug menjadi proyek cukup besar karena jembatan ini berperan sebagai jalur vital penghubung Solo-Karanganyar. Revitalisasi ialah suatu proses atau cara dan perbuatan untuk menghidupkan kembali suatu hal yang sebelumnya terberdaya. Proyek ini berdampak pada lingkungan sekitar akibat bertambahnya volume kendaraan yang menyebabkan gangguan kenyamanan dan kualitas hidup masyarakat di sekitar jembatan, yaitu kebisingan. Dampak kebisingan akan berpengaruh terhadap kesehatan masyarakat seperti gangguan pendengaran ataupun non pendengaran yang mana apabila kebisingan ini berlebih dapat menyebabkan gangguan tidur, stres, masalah pendengaran, dan mengganggu aktivitas sehari-hari. Tujuan dari adanya penelitian ini yaitu untuk mengetahui tingkat kebisingan di Kawasan Jembatan Jurug, mengetahui faktor penyebab kebisingan di kawasan Jembatan Jurug, serta mengetahui pengaruh kebisingan di Kawasan Jembatan Jurug terhadap kenyamanan masyarakat sekitar. Metode yang digunakan berupa riset kepustakaan dan riset lapangan yaitu dengan dilakukan penghitungan kebisingan menggunakan Sound Level Meter dan penghitungan jumlah kendaraan di dua hari dan waktu yang berbeda. Berdasarkan pengujian yang dilakukan, tingkat kebisingan di Jembatan Jurug telah melewati standar baku mutu dan didapati ketinggian pemetaan kebisingannya serta revitalisasi ini berakibat mengganggu kenyamanan masyarakat.
