Abstract

One of the reasons is that road construction in Indonesia is increasing every year. In the construction of toll roads, this activity absorbs more and more workers increase. Besides that, this activity carries the risk of work accidents, by because that is why the safety and health aspects of work K3 must always be important applied in these activities. This research was conducted to find out. Does the occupational safety and health program have an influence on unsafe behavior of workers during the construction of the Bocimi toll road section II. This method uses multiple regression with a cross-sectional approach to see how much influence the independent variable has on the dependent variable. There were 100 respondents in this study, each respondent was given as many as 20 statements using a Likert scale. Based on the results Data processing shows that the influence of safety work program factors and occupational health on workers' unsafe behavior factors obtained t count = -2.283 > t table = -1.984 and calculated f = 5.211 > 3.944. This shows that the influence of occupational safety and health work program factors on unsafe worker behavior. Meanwhile, the relationship between work program factors occupational safety and health with factors of worker unsafe behavior obtained p = 0.025. This shows H1 (there is influence) and the relationship between occupational safety and health work program factors on unsafe behavior worker.

Abstract

One of the areas planned as a swimming pool tourist attraction with natural views is located in Cipelang Village, Cijeruk District, Bogor Regency, which has a land area of 1.5 hectares. The purpose and contribution of the research is to plan a swimming pool system (water treatment) in a tourist pool contaminated by algae bloom. This research will begin by calculating the amount of rainwater discharge and water load on the ground surface, then measuring the water quality of the swimming pool contaminated with algae bloom in accordance with the Minister of Health Regulation Number 2 of 2023, namely Temperature, Turbidity, Odor, Laboratory Acidity Degree (pH), Residual Chlorine, Escherichia Coli. Then continued by compiling a DED (Detail Engineering Design) for the pool structure along with its water treatment. The results of water quality testing for the swimming pool are for parameters Temperature 26°C, Turbidity 0.45 NTU, Odor 1.4, Laboratory Acidity Degree (pH) 5.7, Residual Chlorine 1.75 mg/L, Escherichia Coli <1 CFU/100ml. After being designed for a pump system and implementing a water treatment system in the filtration system and adding PAC (Poly Aluminum Chloride), Alum, Soda Ash Dense USA, and 60% Chlorine Powder chemicals, the results of laboratory tests after the water was clear were that it met the requirements for all parameters.
