The purpose of this study is to determine the risks and hazards in the laboratory, it is necessary to identify hazards, risk assessment and risk control. Laboratories are often found in research and development institutions, service companies, industry and universities. The material laboratory is a place to carry out student practicum activities and conduct research which has a source of danger that can cause work accidents such as chemical explosion, fire, poisoning and ext. Work accidents can be avoided by improving the quality of Occupational Safety and Health (OSH) which is related to the process of doing work safely and working conditions that are safe and comfortable. One effort that can help is to identify hazards and risk assessments so that effective control efforts can be made to increase work productivity and reduce work accidents. Hazard identification is a process that can be carried out to identify all situations or events that have the potential to cause work-related accidents and diseases that may arise in the workplace [1]. Carry out hazard identification to answer the question of what potential hazards can occur or befall the company organization and how it can occur. Hazard identification is the first step in developing OSH risk management and a systematic effort to understand the existence of organizational hazards and is the foundation of an accident prevention and risk control program [2].

The existence of the green campus program is expected to create awareness and concern for the campus community to participate and be responsible for reducing global warming. This research is expected to be a guideline in implementing smart waste management in the Civil Engineering Department of the Bali State Polytechnic in particular to improve quality in the environmental sector. The method of analysis in this research includes: Identification, planning of and quantity of waste generation. The analysis conducted in this study used an analysis referring to several standards regarding green campus, namely UI Greenmetric, Green Guide for University and Greening University Toolkits. Waste management in the Department of Civil Engineering has not carried out processing efforts such as recycling, composting or other integrated efforts. The waste generated from teaching and learning activities, practicum and canteen is carried out by making a reservoir and it is carried out by disposing of waste into the trash bins that have been provided, practicum waste is collected in carts, waste management is carried out in the area of the department such as in the room carried out by cleaning services, which is then the final handling in the campus area, namely garbage is disposed of to the Temporary Landfills (TPS) campus then brought to the Landfills (TPA) by the South Kuta District Sanitation Office. The main objective of the campus solid waste management plan is to maximize resource recovery, with the aim of minimizing the disposal of waste to the TPS. The main strategy is to implement a waste hierarchy by avoiding purchasing products that will eventually become waste, repair and reuse, then recycle, and finally if there is no other choice, disposal to the TPS.

Construction projects contribute to the damage to nature, among others, from material extraction, material processing, material distribution, construction processes, land acquisition for buildings and energy consumption in building operations. Besides that, construction activities also produce high enough waste. One of the discussions to overcome the problem of global warming and construction waste is to promote sustainable construction or what is often referred to as sustainable construction. In the green construction concept, one of the things that needs to be considered is waste management. The purpose of this study is to determine construction activities that have the potential to cause the construction material residuals that arise in construction projects and analyze mitigation actions to minimize the occurrence of material waste. The methods used for data collection are field observations, interviews and questionnaires. Data analysis uses qualitative analysis to determine dominant activities as a cause of waste material and mitigation actions that can be done. The results of the study stated that the activity as a potential factor causing potential waste material in building construction projects in Badung regency which most often occurred was "lack of skilled labor" with a mean value of 4.22 while the activity as the causative factor that had the greatest impact on influence was "quality material does not match specifications "with a mean value of 1.51. From the waste risk matrix, it is found that "lack of skilled labor" is included in the category of very high waste risk due to the frequency that often occurs so that it is a very serious disruption to project implementation and corporate finance.
