Introduction: e Covid19 virus has an outer lipid sheath that is not tolerant towards disinfectants, but this virus can quickly infect humans with a fairly high mortality rate. The increasing Covid19 patients directly proportional the amount of solid medical waste production in hospitals. This study aims to identify the health protocol in solid medical waste management in one of the Covid19 patient referral hospitals in Surabaya, East Java. Method: We used descriptive observational research with secondary data for the data compiling method. The obtained data were then compared with the 2020 Guidebook on Waste Management in Referral Hospitals, Emergency Hospitals, and Public Health Centers that Handles Covid19 Patients, issued by the Ministry of Health of the Republic of Indonesia. Result and Discussion: Research results showed that the management of all solid medical waste yielded from the Covid19 Special Isolation Room is directly infectious, went through the incineration process using an incinerator with the primary burner set at 800o C and the secondary burner set at minus 1.000o C. The usage of Personal Protective Equipment (PPE) by medical waste trolley carriers was inappropriate. The officers only used surgical masks, head caps, gloves, shirt, and work shoes, without using any apron. Conclusion: Health protocol for medical waste management in one of the Covid19 patient referral hospitals in Surabaya, East Java has been implemented, but the usage of PPE by medical waste trolley carriers was still inappropriate.

One of air pollution parameters that are harmful to human health is the amount of dust. The main source of the dust pollutant is a limestone grinding activities. The purpose of this study was to look at the description of workers pulmonary function status, physical quality of the work environment, and respiratory complaints that experienced by workers in the limestone milling industry. This research design was descriptive cross sectional study. All of 12 workers in limestone milling industry were recruited in this study. Physical quality of the environment that have seen was the amount of dust particle, air temperature, humidity, and wind speed. Characteristics and respiratory complaints worker measured by questionnaires. Lung function disorder was measured using spirometry. The result of the physical quality measurement of the environment still met quality standards. Respiratory complaints most experienced by workers was phlegm, cough, cough with phlegm, and cold conditions. A total of 100% workers in production and 83.3% of workers in the packing have impaired lung function. It is concluded that, lung function disorders more experienced workers with the working environment had higher levels of dust and higher temperatures, lower humidity. Judging by the characteristics of workers, impaired lung function more experienced workers by aged 20-29 years and 30-39 years old, have years of service more than 5 years, smoking habits, have normal status nutrition, not wearing protective respiratory tract, and not have a history of lung disease. It is suggested that, the workers with impaired lung function should immediately conductfurther tests to get proper treatment. In addition, workers should always wear respirator while working and quiet from smoking behavior.Keywords: dust particle, lung function status, limestone milling industry workers

Lead  (Pb) is one  of the pollutants  that can cause hypertension. The objectives of this study  were  to analyze characteristic, levels  of Lead (Pb) in blood  and hypertension at home industry workers  batteries.  This research was an observational descriptive studies and used cross-sectional approach. Data obtained from interviews, questionnaires, and observation. Measurement of blood  lead used Atomic Absorption Spectrophotometer and blood  pressure measurements used a tensimeter. Samples were selected by total population of 10 workers  batteries  home industry. The results  of the research that most workers  age is less  than 30 years was 50%, the worker men  was 60%, workers  who have a habit of smoke was 30%, Pb levels  in the blood  of workers  30% above the standards set by ATSDR (1999) < 10 μg/dL,  and 40% of workers  have hypertension. Cross-tabulation showed  that workers  who have hypertension that workers  aged 31–40 years (50%), workers  with employment ≤ 5 year period  (40%), male workers  (66.7%), workers  who was smoke (100%), workers  with no history of hypertension and diabetes (40%) and workers  who  have  levels  of lead (Pb) in the blood  > 10 μg/dL (100%). Advise  the workers  to reduce cigarette  consumption and wear personal protective equipment such as masks, gloves and boots while they work to reduce exposure of lead (Pb).Keywords: characteristic of workers,  levels  of lead (Pb) in the blood, hypertension, workers  home industry batteries

Introduction: Covid19 was an acute respiratory disease with fever, cough, and out of breath as the symptoms. WHO reported that until June 21st 2020, there were 8,708,008 cases were confirmed with 461,715 number of death (CFR 5.3%). In Indonesia, there were 45,891 cases were confirmed with 2,465 number of death (CFR 37%). People who were most at risk were people who physically close contact with the Covid19 patient, including health workers. The purpose of this study was to know the microbiology indoor air quality of Covid19 patient at Hospital before and during the pandemic. Method: The study design of this research was observational cross sectional. The study was done at a Hospital in East Java on December 2019 – June 2020. The sample of this research was a ward’s air in a Hospital. The research variable was the number of microbiology, temperature, and humidity of the ward of Covid19 patient that was measured 3 different points of measurement each rooms. Result and Discussion: The result showed that the average of the number of microbiology before the pandemic was about 46.31 CFU/m3 with the average of the temperature was 27.64°C and the humidity was 44.58%, while during the pandemic the number of microbiology in the air increased to 64 CFU/m3 with the average of the temperature was 27.77°C and the humidity was about 42.46%. Based on the statistic analysis, there were differences between the numbers of the microbiology before and during the pandemic in the ward of Covid19 patients (p value 0.00). Conclusion: The result showed that the number of the microbiology was increased before and during the pandemic although it was still under the quality standard. Increasing of Covid19 patient was the probably reason of the increasing the number of the indoor air microbiology. It was recommended the hospital requires to control the air quality of the treatment room by regulating air ventilation.

The production process of knowing the traditional poultry requires a supervisory system with Good Manufacturing Practices (GMP) approach as stipulated in Regulation of BPOM Head of 2012 on Good Food Making. The quality of tofu produced by a domestic industry must be in accordance with Indonesian National Standard (SNI) 01-3142-1998 about the quality of tofu so that the products know that piety produced safe. This study aims to analyze the quality of know-how with the approach of Good Manufacturing Practices (GMP) and consumer attitudes toward tofu products in one household industry in Kediri. This research was descriptive with cross sectional approach. Aspects of GMP examined were the location and environment of production, buildings and facilities, production equipment, water supply or water supply facilities, hygiene and sanitation facilities and activities, storage, process control, food labeling, supervision by persons responsible, product recall, record and documentation, and employee training, and see the quality of the IRT. The results of the assessment of the implementation of GMP on IRT know this pardon of 59.67%, included in the category of poor assessment. Therefore, it was necessary to improve the production process from the IRT to know piety against the unfavorable aspects, such as facilities and hygiene and sanitation activities, maintenance and hygiene and sanitation programs, storage, supervision by the responsible person, and recording and documentation, so that aspects it complies with the standards and produces quality tofu according to the standard.
