Nurses are working with high expectation, especially nurses at inpatient care unit are. They are to always be ready to  provide health treatment to the patients for 24 hours for 7 days. This high expectation may affect and inflicting fatigue on them. Work fatigue is a condition of activity, motivation and physical exhaustion. If nurses don’t take a rest, it can accumulated work fatigue eventually drops the health condition of the nurse off. This research aims to analyze level of work fatigue based on physical workload of the nurses in Inpatient Care Unit of RSU Haji Surabaya. This observational descriptive study applied cross-sectional study design. The research was conducted nurses at ward IIIC and IVC. The respondents are 27 nurses with following the criteria of this. The research applied Kruskal Wallis test to find out the variety of the work fatigue level based on physical workload and Spearman correlation test to find out the relationship between physical workload and work fatigue. The result showed that several characteristics of most of the respondents were aged between 30 and 49 years old, female, had been working for more than 5 years, married, normal nutritional status, and low calorie intake. The result also showed the average workload and the nurses might experience moderate work fatigue. The result of inter-variables correlations indicated there were correlation between physical workloads and work fatigueand there are varieties of the work fatigue based on the physical workload. Keywords: nurse, physical workload, work fatigue

Background:Ammonia is one of the chemical compounds that can cause acute and chronic effects to the workers. The purpose of this study is to determine the no-observed-adverse-effect level (NOAEL) ammonia in white mice.Methods:This study applied a laboratory experimental with design post test-only control group design using white mice as an object. The process of finding the safe limit began by determining the highest dose and the lowest dose of ammonia without effect in white mice.Results:The latest research showed that the highest dose without effect is 0.0456 mg/kg and the lowest dose without effect is 0.0046 mg/kg. After determining the highest and the lowest dose of ammonia, the researcher started to determine the middle dose. The middle dose is the dose between the highest and the lowest doses with the multiplication of 1.5 starting from the lowest dose (there are 5 middle-dose variations from 5 middle concentration variations), consisting of 0.0872, 0.1309, 0.1963, 0.2944, and 0.4416 mg/m3.Conclusion:From the result of the middle dose and the lowest dose without effect, it is found the value of the highest NH3 dose without effect, which showed the highest Index Remmele Scale (IRS) CD4 before the reduction of IRS. The study concludes that the NOAEL of ammonia contained in white mice is 0.0103 mg/kg body weight of the mice.

Welding have several potential to cause work accidents. Therefore, it is necessary to prevent work accident, one of them through safety culture. Safety culture is made up of three factors: psychological factors, job factors, and situational factors. The purpose of this study is to analyze safety culture based on the factors of safety culture in welders in shipyard company. This research was an observational research using crosssectional design. The variables were safety climate, safety behavior, and safety culture. The results showed that most respondents had a very good perception of OSH and the safety climate profile was in a good category, most respondents had good safety behavior and safety behavior profile was in a good category. In addition, most respondents had a very good safety culture and profile of safety culture was 74,89% and in a good category. Based on these results, it is expected to develop the safety culture and make some efforts to improve the safety behavior of welder. The management of this shipyard company may take action to perform an analysis of safety culture level as a form of oversight of the existing safety culture.

Pengolahan sampah berbasis 3R merupakan salah satu alternatif pengolahan sampah yang ada di Indonesia. Akan tetapi, konsep pengolahan ini masih belum diketahui seluruh lini masyarakat, khususnya masyarakat pedesaan. Oleh karena itu, perlu dilakukan pengenalan pengolahan sampah berbasis 3R pada masyarakat pedesaan agar masyarakat dapat mengurangi produksi sampah, dapat memilah sampah sejak dari rumah tangga, dan dapat melakukan daur ulang sampah yang pada akhirnya dapat membantu mengurangi timbulan sampah yang ada di TPA. Adapun tahapan pelaksanaan kegiatan ini adalah identifikasi masalah, sosialisasi pengolahan sampah berbasis 3R, dan praktik pengolahan sampah organik (kompos). Kegiatan pengabdian masyarakat berjalan dengan lancar dan sesuai dengan rencana yaitu terlaksananya sosialisasi pengolahan sampah berbasis 3R dan praktik pengolah sampah berbasis 3R. Masyarakat antusias mengikuti kegiatan karena hal ini merupakan hal baru bagi mereka. Diharapkan ke depannya dapat dilakukan kegiatan pengabdian masyarakat untuk melihat penerapan pengolahan sampah berbasis 3R, sehingga dapat diketahui lebih pasti perubahan perilaku masyarakat dalam melakukan pengolahan sampah.
