In general, inpatient health care facilities produce infectious and non-infectious waste 0.3 mᶟ / day. Non-infectious waste that is burned in an incinerator without a chimney filter, can cause particles, CO, SO2, NOx (air pollutants) and cause environmental pollution. This study aims to make a chimney filter design with a Scrubber model on an incinerator at the Public Health Center, Maospati District, Magetan Regency to reduce the amount of air pollutants emitted. This type of research is experimental research. This research designed a particle trapping device, gas by spraying water into the scrubber. The independent variable of this research was the variation of the water flow sprayed in the scrubber (3.2 liters / minute, 4 liters / minute, 5.6 liters / minute). The dependent variables of this study were particles, SO2, NOx, CO. Data collection using a digital gas detector method in the form of a UV spectrophotometer. Data were analyzed descriptively, in the form of frequency distribution, and percentage, presentation of data in a table based on air emission quality standards from thermal waste processing. The results illustrate that the use of a chimney scrubber filter with water spraying 3.2 liters / minute, 4 liters / minute, 5.6 liters / minute can reduce air pollutants, emission of SO2, CO to below the air quality standard. In addition, this tool can also reduce NOx gas and particles, but not yet below the quality standard. The conclusion from the results of this study is particulate emission air pollutants, gas SO2, CO, NOx. the incinerator can be lowered by modifying variations by spraying water 3.2 liters / minute, 4 liters / minute, 5.6 liters / minute on the chimney scrubber filter on the incinerator.

Mie adalah produk pangan yang terbuat dari tepung terigu dengan atau tanpa penambahan bahan pangan lain berbentuk khas mie. Makanan ini sangat digemari mulai dari anakanakhingga dewasa. Untuk mengurangi kerugian karena mie tersebut tidak layak untukdikonsumsi lagi, maka pedagang menambahkan zat-zat kimia berbahaya sepertiformaldehid/formalin. Jenis penelitian ini adalah deskriptif yaitu mengumpulkan semua data kemudiandideskripsikan. Pengumpulan data dimulai dari data tentang perilaku penjual mie basah khususnyapada saat proses pengolahan dan penyimpanan, identifikasi dari aspek organoleptik danpemeriksaan laboratorium terhadap kandungan formalin pada mie basah. Berdasarkan hasil penelitian, perilaku pedagang A diperoleh hasil dengan nilai 24,6kategori kurang dan pada pedagang B diperoleh hasil dengan nilai 34  kategori kurang. Untuk hasilpemeriksaan formalin, diketahui jumlah kadar formalin pada pedagang A sebanyak 0,45 mg/lt danpada pedagang B sebanyak 0,80 mg/lt dengan rata-rata kadar formalin sebesar 0,625 mg/lt. Dari hasil pengamatan organoleptik dapat disimpulkan bahwa mie basah tersebut tidak layak untuk di konsumsi, karena aroma mie basah sedikit berbau formalin dan teksturnya kenyal. Disarankan kepada masyarakat untuk lebih berhati-hati dalam memilih makanan yang baik terutamamie basah, hindari mie basah yang bertekstur kenyal dan berbau formalin.

Introduction: Livestock population in Magetan, East Java Province, Indonesia is quite high, which is 58.671 animals This can be become a potency for development of organic fertilizer with fresh cow dung as the raw material. For producing biogas from cow dung, it needs to be conducted appropriate technological innovation, thus, it can be used and can reduce environmental pollution. Methods: The research’s method was eksperimental research. Purpose: Identifying the measuring the levels of: macronutrient of organic fertilizer in this research: N, P, K, and C-organic. Analyzing exact fermentation time in making organic fertilizer from variation in the comparison of molasses. Result: The organic levels of N, P, K and C showed that it qualified the standard of Regulation of the Ministry of Agriculture Number 70/ PERMENTAN / SR.140 / 102011. Based on the research result, it was obtained that the fastest of fermentation time was in variation 4 with the comparison of addition of molasses dose in 200 ml and EM4 in 50 ml.

Refill Drinking Water Depot (DAMIU) is a business entity that manages drinking water for consumer needs at a price that is relatively cheap and easy to reach for consumers whose economy is middle to lower. If the processed product of the refill drinking water depot does not meet the requirements, it can cause the spread of disease.. The sample population was 24 samples from the inlet and outlet by doing 2 treatments at each Refill Drinking Water Depot. Laboratory examination was carried out with Microbiological Parameters, namely Coliform Bacteria in accordance with the quality standards of the Regulation of the Minister of Health of the Republic of Indonesia No. 492/Menkes/PER/IV/2010. The results obtained by conducting laboratory results that from 6 refill drinking water depots in the work area of the Parang Health Center, Magetan Regency, do not meet the requirements. And from the results of the Observation Sheet, it was found that the Filtration results contained 3 Refillable Drinking Water Depots that met the requirements and the results of Disinfection there were 3 Eligible Refill Drinking Water Depots. From this research, it can be concluded that from the 6 Refill Drinking Water Depots in the Work Area of the Parang Health Center, Magetan Regency, they do not meet the requirements and the results of the observation sheets from the 6 Refill Drinking Water Depots in the Parang Health Center Work Area, Magetan Regency do not meet the requirements due to the filter.

Personal Protective Equipment (PPE) is a tool used to prevent or minimize the occurrence of work accidents. Compliance with the use of PPE must be carried out by every worker who will enter the work area. This research was conducted at PT. Syngenta Seed Indonesia with the aim of knowing the description of worker compliance in the use of personal protective equipment at PT. Syngenta Seed Indonesia. This study uses a descriptive type of research. Data collection in this study was obtained by means of observation and questionnaire surveys. The sample of this research is all permanent workers in the production division as many as 24 workers. The variables studied were trust, accept, act, and worker compliance in the use of PPE.The purpose of this study is to determine the level of employee confidence in using PPE. The results of the study indicate that the trust aspect of the workers is mostly in the good category. While the aspects of receiving (accept) and aspects of doing (act) workers are mostly in the less category. From the aspect of believing (belief) as many as 18 (47%) workers are obedient, aspects of accepting (accept) as many as 11 (29%) workers are obedient, and aspects of doing (act) as many as 9 (24%) workers are obedient in the use of PPE so that the value of compliance is obtained. workers by 38 (100%). The conclusion of this study is that workers who have a good level of confidence in the use of PPE do not necessarily manifest in attitudes and actions because it can be caused by several factors, one of which is the convenience of using PPE.
