ABSTRAK Kajian risiko pajanan radiasi gama dan gas radon dilakukan di area terowongan eksplorasi uranium dalam upaya melindungi pekerja dari bahaya radiasi pengion di tempat kerja. Pengukuran pajanan sinar gama dan konsentrasi gas radon dilakukan di dalam terowongan eksplorasi uranium Remaja dan sekitar kamp pekerja di daerah Kalan, Kalimantan Barat. Pajanan sinar gama diukur menggunakan surveimeter gama, sementara pajanan radon (222Rn/220Rn) menggunakan detektor pasif RADUET. Konsentrasi gas radon dan toron di dalam terowongan secara umum cukup tinggi, berkisar antara 188,84 hingga 495,86 Bq/m3 (rata-rata 375,80 Bq/m3) sementara toron berkisar antara 58,07 hingga 340,73 Bq/m3 (rata-rata 189,80 Bq/m3). Nilai tersebut berada di atas reference level radon (300 Bq/m3) yang disaranakan oleh International Commission on Radiation Protection (ICRP). Dosis efektif tahunan sinar gama mencapai nilai 147,88 mSv di dalam terowongan eksplorasi. Nilai tersebut berada di atas nilai batas dosis untuk pekerja, yaitu 20 mSv. Pengendalian pajanan sangat penting dilakukan dengan memenuhi prinsip “as low as reasonably achievable” (ALARA) dan proteksi radiasi eksterna untuk melindungi pekerja di dalam terowongan dari masalah kesehatan yang disebabkan oleh pajanan dari sinar gama, radon, dan toron.ABSTRACT A risk assessment of gamma radiation and radon gas exposure is carried out in the uranium exploration tunnel area to protect workers from the ionizing radiation hazards in the workplace. Measurement of gamma-ray exposure and radon gas concentrations were carried out in Remaja uranium exploration tunnel and around the workers camp in Kalan Area, West Kalimantan. Gamma exposure was measured using a gamma survey meter while radon (222Rn/220Rn) using RADUET passive detector. The concentrations of radon and thoron gas inside the tunnel generally are high, ranging from 188.84 to 495.86 Bq/m3 (375.80 Bq/m3 average) and 58.07 to 340.73 Bq/m3 (189.80 Bq/m3 average) respectively. These values are above the radon reference level (300 Bq/m3)which is recommended by the International Commission on Radiation Protection (ICRP). The annual gamma effective dose reaches 147.88mSv inside the tunnel. This value is exceeding the 20 mSv dose limit value for workers. It is necessary to control the exposure by fulfilled the principle of “as low as reasonably achievable” (ALARA) and external radiation protection to secure workers inside the tunnel from a health issue caused by gamma-ray, radon, and thoron exposures.

To April 2021, COVID-19 cases in Indonesia reaches 1.668.368 with the death cases are 45.334. The increasing death cases due to COVID-19 worldwide and the presence of 14 employess exposed to COVID-19 in the project area specifically encouraged this study. This study aims to observe the relationship between individual factors and the risk perception againts COVID-19 among the employess in LRT Project PT X during April-May 2021. The results revealed that based on the individual factors, the composition of the respondents are 83,3% of male, aged 20â€“30 years old (56,7%), hold a bachelor degree (58,3%), have not infected with COVID-19 (88,3%), and do not have a chronic disease (100%). Overall, the risk perception of the respondents is relatively high (51,7%; n=62), and as much as 48,3% (n=58) of respondents have low risk perception against COVID-19. The result of the risk perception analysis showed that the factor of age has a significant relationship with the level of risk perception, level of knowledge, potential impact, readiness and self-efficacy, fear, severity, and voluntary of risk. The factor of gender is significantly related to readiness and self-efficacy, novelty, and severity. The education level is known to have a significant relationship with the entire variabels of risk perception. However, the factor of COVID-19 infected history is significantly related to the knowledge level, control over risk, and novelty. The health status of the respondents has a constant value because no respondent has a chronic disease so its relationship to other variables cannot be statistically made.

Benzene bersifat toksik dan karsinogenik ditemukan dalam proses operasional Kilang Paraxylene di PT. X. Kilang ini dibangun mengolah bahan Naphtha menjadi berbagai produk bahan bakar berdaya jual tinggi. Proses ini menjadikan para pekerja terpajan pada benzene sehingga perlu dilakukan analisa pajanan benzene terhadap pekerja melalui pemeriksaan konsentrasi benzene di lingkungan dan konsentrasi metabolit benzene pada urin melalui pemeriksaan SpMA. Metode desain penelitian adalah analisa kuantitatif dengan metode potong lintang dari data sekunder hasil pengukuran pajanan personal dan biomonitoring. Jumlah sampel penelitian sebanyak 64 sampel. Hasil penelitian menunjukkan bahwa konsentrasi pajanan personal benzene berada di bawah NAB (NAB Permenaker No 5/2018: 0,5 ppm), namun sebanyak 28 responden (43,75%) memiliki kadar SpMA Urin melebihi Indeks Pajanan Biologis (ACGIH 2020: 25 µg/g kreatinin) dengan median 20,34 µg/g kreatinin. Hasil analisa menunjukkan bahwa tidak terdapat hubungan yang signifikan antara konsentrasi pajanan personal benzene dengan kadar SpMA Urine dengan nilai p=0,287. Namun, dari uji statistic ditemukan adanya hubungan signifikan antara kadar SpMA dengan lama bekerja dengan nilai p=0,04. Pada beberapa area di Kilang Paraxylene terdapat konsentrasi benzene di udara yang tinggi namun konsentrasi benzene yang terpajan personal di dekat area pernafasan pekerja selama 1 shift kerjanya masih di bawah nilai ambang batas. Namun dengan adanya hubungan antara metabolit benzene di tubuh pekerja dengan faktor lama kerja menandakan bahwa dosis pajanan yang rendah namun diterima dalam jangka waktu yang lama menimbulkan resiko pada tubuh pekerja. Perusahaan perlu menerapkan pengendalian rotasi kerja yang lebih baik lagi

Introduction: Workers face pressure that comes from the work environment, one of which is heat pressure. Exposure to heat, workload, rehydration, and rest period are several factors that can cause heat stress to workers. People who are uncovered to heat are much more likely to experience heat stress. Related to this, current research was carried out aiming to analyze environmental factors that are at risk of heat stress exposure to fishermen in Indonesia. Methods: This study was conducted through a cross sectional design in the coastal regions in Surabaya. Accidental sampling technique was applied, obtaining 42 respondents. In this case, the variables included are humidity, temperature, access to clean water, risk of heat stress, and dehydration, while the data analysis techniques used are the logistic regression and pearson correlation. Results: The results showed that the significant environmental factor is access to clean water, with a value of 0.009 so that the p-value is less than 0.05. Furthermore, the relationship between heat stress and dehydration is 27.1%. Conclusion: Therefore, this study concludes that only access to clean water is significantly related to the risk of heat stress. In addition, the relationship between heat stress and the incidence of dehydration is weak.

Introduction: In line with the increasing number of COVID-19 cases from July to early August 2022, this paper aimed to analyze the perception of COVID-19 among Indonesians. Methods: A cross-sectional online study on COVID-19 risk perception was conducted in the first week of July 2022. A questionnaire adapted from ECOM (Effective Communication in Outbreak Management for Europe) was distributed online through social media to obtain information about the respondents' knowledge, behavior, and risk perceptions on COVID-19. Results: There were 775 respondents. Most of them were female (61.3%), lived in the eight most targeted areas (84.1%), were unmarried (52.5%), held a bachelor's degree (38.5%), and were Muslims (80.8%). The percentages of respondents who had been infected with COVID-19 were (43.8%). Most participants believed that their knowledge level of the disease was average and above average (>91%). Of the respondents, 83.6% perceived the seriousness of COVID-19 as serious and very serious. However, the anxiety level among these respondents was moderate (slightly and quite anxious). This indicates that even though most respondents still see COVID-19 as a serious disease, their level of fear is decreasing. Compared to a previous study, most respondents in the current study were more confident of their ability to control the risks associated with the transmission of the virus. Nevertheless, they still believe that outdoor activity and not using a face mask can significantly increase the probability of getting infected. Conclusion: The risk perception of COVID-19 in Indonesian community among our study population was appropriate.

Introduction: The COVID-19 pandemic in Indonesia has not officially ended, and due to the apparent underestimation of protective behavior, it is imperative to continuously promote public awareness and implement health protocols to control its spread. Therefore, this study aims to analyze the community's risk perception and experiences of COVID-19 transmission in Indonesia. Method: This study was conducted in 2022 using an online survey. The questionnaire was developed based on a standard questionnaire (ECOM, 2015) on the risk perception of an infectious disease outbreak. It was then distributed through various social media platforms, including WhatsApp, Facebook, and Instagram. Result: According to all ten risk perception distribution data, the majority of respondents considered COVID-19 a threat. This showed that most respondents had intense COVID-19 transmission directly or indirectly. This study also revealed that there were more female respondents than men. Conclusion: Individuals who had contracted COVID-19 might have different perceptions compared to those who had not been infected. Furthermore, experiences such as the COVID-19 transmission involving relatives and friends might also shape an individual's risk perception, particularly in implementing protective behavior, in this case, health protocol. Control measures based on gender should also be considered to ensure the effectiveness of the COVID-19 risk management.
