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.

Bangli solar power plant has 5004 solar modules and uses concrete foundations to support those modules. Due to the location of this power plant was a former landfill, after 5 years in operation, 121 foundations have dropped to lower level. The soil under foundation is not enough to support modules sufficiently. In this paper, a new design has been proposed to correct this problem. The first step is to test the carrying capacity of soil through Sondir boring. Using Standard Penetration Test (SPT) obtained that the layer of hard soil is located at a depth of -10m from the original soil surface with type of soil layer above the elevation of hard soil in the form of silt soil. Using a palm foundation, carrying capacity of a foundation with a width of less than 1.2 meters and a depth of foundation of 1 meter. This makes the average carrying capacity is only 0.39 - 1.20 kg/square cm or the value is too small for foundation of solar power plants. The proposed foundation is a 50 x 50 cm palm foundation that is laid on a geotextile bed. The area of the geotextile depends on the area of decreased foundation.

Media pembelajaran merupakan bagian yang sangat penting dalam dunia pendidikan khususnya bagi guru. Salah satunya adalah overhead projector (OHP) yang merupakan alat bantu yang banyak digunakan dengan Ms. PowerPoint sebagai perangkat lunaknya. Dengan cara ini guru akan dapat lebih mudah memberikan materi pelajaran kepada siswa. Namun tidak semua guru dapat mengoperasikan OHP dan membuat presentasi menggunakan Ms. PowerPoint, termasuk guru-guru di SDN 1 Kesiut. Untuk itu melalui program pengabdian kepada masyarakat, guru-guru tersebut diberikan pelatihan penggunaan OHP dan pembuatan slide PowerPoint yang efektif. Hasilnya adalah adanya peningkatan pengetahuan (mean normalized gain) rata-rata para guru sebesar 74% dengan rata-rata pemahaman materi pelatihan sebesar 8,33 dari nilai maksimum 10. Jadi setelah mengikuti pelatihan ini, pengetahuan para guru bertambah secara nyata.
