Abstract

Waste has become a problem in city/regency. The waste produced originates from daily activities. The study was conducted between June and October. The aim of this research was to analyze the level of knowledge and participation of students as the younger generation in waste management. Data were obtained using questionnaires administered to 177 young participants. The obtained data were descriptively analyzed. The results showed that 87% of the students knew the importance of processing the waste produced so as not to pollute the environment. However, only 32% had processed waste. The processing includes converting organic waste into compost or eco-enzymes.

Abstract

Occupational Health and Safety (OHS) in work environments is crucial for optimal productivity. Work accidents affect productivity because they can reduce working hours and decrease productivity. The problem faced by a company is the absence of a Key Performance Indicator that explicitly considers the safety aspect. This study aims to determine and calculate the key performance indicator safety of KPIs and implement a correlation between work accidents and productivity. Key Performance Indicator data processing Safety consists of leading indicators for potential future events and lagging indicators for past accident data using the Safe T-Score method to determine the effect of accident rates on work productivity. The Key Performance Indicator calculation results for safety showed good performance, with a total actual value of 94.74%. The results show that the Safe T Score is 2.68 in 2022 and -1.61 in 2023, indicating little change in the occupational health and safety program. The results show a positive relationship between occupational safety and productivity; the fewer the accidents, the higher the productivity.

Abstract

The increasing population in Bogor City, especially in the Tanah Baru area, leads to an increase in the volume of domestic wastewater and municipal waste such as chicken eggshells. Chicken eggshells have the potential to be used as an environmentally friendly biocoagulant to reduce pollutant load, but their effectiveness on domestic wastewater still needs to be studied. This study aims to analyze the effect of adding chicken eggshell biocoagulant on changes in pH, TDS, and conductivity parameters of domestic wastewater and compare it with the conventional coagulant polyaluminum chloride (PAC). The methods used include preparing chicken eggshell powder through washing, drying, grinding, sieving, and chemical activation, then applying it to wastewater samples at a dosage of 50 g/500 mL and comparing it with PAC at a dosage of 1 mL/500 mL using the jar test. The results show that adding chicken eggshell biocoagulant did not significantly reduce pollutant load, even causing an increase in TDS and conductivity, while PAC was able to improve wastewater quality with much lower increases in TDS and conductivity, and the pH remained within the quality standard range. These findings indicate that chemically, chicken eggshells are more suitable for use as an adsorbent or support material in coagulation systems than as the primary coagulant in domestic wastewater treatment.

Abstract

Household activities generate large amounts of organic waste. Improper waste management can negatively impact the environment. Several areas, including Mulyaharja in Bogor, still face difficulties in managing organic waste. This is because the practice of sorting and processing organic waste has not yet been widely introduced and implemented. An alternative solution to reduce the negative impact of poor organic waste management on the environment is to process it into eco-enzymes. In addition to reducing the amount of waste disposed of in landfills, eco-enzymes can also function as a natural cleaning solution for daily household use. To introduce this processing method, a sustainable waste processing program was carried out in Mulyaharja through two activities. The first activity was the socialization of the definition and processing of organic waste, as well as the types of organic waste that can be used to produce eco-enzymes. The second activity was hands-on training in processing organic waste into eco-enzymes, so that the community could fully understand the tools, materials, and stages of its production. The main ingredients in making eco-enzymes are fruit and vegetable peel waste, molasses, and water. After the eco-enzyme solution was ready, this solution could be used to clean toilets, bathrooms, floors, and kitchen surfaces. The results of the program showed an increase in community knowledge and skills in processing organic waste, as well as increased adoption of environmentally friendly cleaning products as alternatives to chemical cleaners.
