This paper assesses the potential ecological risk of hexavalent chromium (Cr(VI)) and silicon dioxide/silica (SiO

) in well water. Both of pollutants have been classified as carcinogenic compound. The ecological risk assessment of drinking water is an effective tool to evaluate drinking water quality to reduce further risk.

Fourteen well water samples were collected around the residential area near cement industrial activity and karst mining area. Estimating the ecological risk of well water which consumed daily evaluated based on Hazard Quotient (HQ) ratio.

The mean values of Cr(VI) and SiO

in well water samples were 0.0017mg/L and 12.94mg/L, respectively. Drinking water in this area are unacceptable. HQ values for SiO

at all stations are more than 1 (moderate level).

Cr(VI) and SiO

are discoverable within well water surrounding the research location. This finding is used as scientific data and references for ecological protection of drinking water in Maros.

To identify factors related to the stress levels among pregnant women in Indonesia.

The study was used cross sectional design. The participants were 92 pregnant women who worked at a footwear manufacturer at Banten, Indonesia. Half of the participants worked less than 40h per week and the other half worked 40h or more per week. A test instrument to measure stress in pregnant women was developed and conducted in this study. Dependent and independent factors were analyzed by the chi-square test.

Our results showed that 59.78% of respondents had their gestational age was more than 31 weeks; 53.00% of workers experienced moderate stress; and as many 53.26% of respondents experienced a high workload.

Our conclusion confirmed gestational age, workload, and working time related with work stress level of pregnant women significantly.

Our conclusion confirmed gestational age, workload, and working time related with work stress level of pregnant women significantly.

This study wants to evaluate heavy metals pollution and ecological risk level of well water in Pangkajene watershed area.

The total concentration of Cd, Cr(VI), Pb and Ni were determined using AAS. We used heavy metal pollution index (HPI), metal index (MI), hazard quotient (HQ) used to estimate metals pollution and ecological risk level. Pearson correlation analysis is executed to evaluate the relationship between all measured parameters.

The concentration of Cd, Ni and Pb are below detection limit value. The mean concentration of Cr(VI) 0.0017±0.0006mgL

. The mean of HPI and MI value are 3.06 and 0.06, respectively. The upstream area of Pangkajene has HQ value for Cr(VI) is higher than 1, it indicates that exposure of Cr(VI) may cause adverse effects to the ecological system and human health.

The Cr(VI) is the main risk factor for well water contamination surrounds Pangkajene watershed area.

The large-scale social distancing policy conducted twice was unable to reduce the rate of development of COVID-19 widespread in Makassar, yet it increased. One of the causes was that social awareness is still lacking especially for people in the poverty line. This study attempts to describe the social behavior of people in poverty line toward COVID-19 case in Makassar.

This research is a qualitative descriptive study based on the case. The data analysis was undertaken qualitatively.

The results revealed that the limited understanding of people in poverty line about COVID-19 and health protocols makes their behavior indifferent and disobedient to health protocols. In addition, the government's top-down approach to deal with COVID-19 pandemic was ineffective. However, bottom-up collaborative interventions need to be carried out through a group approach to gain an understanding of the COVID-19 health protocol, especially for people in poverty line and other vulnerable groups.

The research aims to identify human error committed by traditional divers while fishing, and to determine the relationship between human error as a cause of occupational accidents at sea.

A cross-sectional study with total of 186 traditional divers participated. The data was collected by questionnaires, and analyzing with chi-square test (p-value=0.05).

More than 83% of respondents had experienced occupational accident and behave human error while diving (81%). Type of human error such as rush of work, never attend safety training and does not have diving certificate, dives more than 30min, continues to work even tired, dives more than once a day, and continues to dive despite bad weather. The types of occupational accidents were slips, scratches, shipwrecks, hit by rocks, and suffered open wounds. The statistical test p value=0.000 (<0.05) and OR=44.883.

There is a relationship between human errors and occupational accident.

The study aimed to find the factors that contributed greatly to health complaints due to use of pesticides.

The research using the cross-sectional research design. The sample was determined using a total sampling technique. Data analysis was performed by path analysis using Smart PLS.

The result of the study found that the use of pesticides affected the working time t-statistic 3.467. GSK690693 cell line The use of pesticides affects health complaints t-statistic 2.586. Types of pesticides affect working time t-statistic 2. Improper timing of spraying and the frequency of spraying has a bigger impact on farmers' health complaints.

Spraying time has the greatest influence on health complaints. It is recommended that farmers reduce the frequency of spraying more than 2 times a day, spraying time in the morning, and pay attention to the wind direction to reduce exposure and health hazards due to pesticides.
