Abstract

PKBM Mutiara is a non-formal education institution in Pemalang district which was founded in 2007. Currently PKBM Mutiara has 15 employees who have different duties and responsibilities. The chairman of PKBM stated that recently there had been complaints of work fatigue from several employees. Therefore, PKBM Mutiara wants to know the workload borne by each employee. The workload analysis method used is the NASA TLX method (National Aeronautics and Space Administration Task Load Index). Employees will assess their workload conditions based on 6 dimensional measurement factors, namely Mental Needs (KM), Time Needs (KW), Physical Needs (KF), Effort (U), Work Performance (PK), and Frustration Level (TF). Based on the calculation of employee workload scores at PKBM Mutiara, It is known that there are 2 employees whose workload is in the "very high" category, 10 employees have a "high" workload, and 3 employees have a "medium" workload. The identification results using the fishbone diagram show that the high workload of PKBM Mutiara employees is influenced by methods and human factors. Proposed improvements to increase employee workload levels are: 1. Distribution of duties and responsibilities according to employee abilities; 2. Reduce the workload of secretaries by recruiting special employees for dapodik operators; 3. Encourage the Education Department to create a technical manual for PKBM management; 4. Carrying out online teaching and learning process training for tutors; 5. Create a system such as Google form or similar for the registration process for prospective new students.

Abstract

Microplastic pollution, particularly from textile waste, has become a significant environmental concern, especially in urban runoff systems. These pollutants pose a considerable threat to water quality, aquatic life, and human health. Traditional wastewater treatment methods often fall short in addressing the complexities of microplastic contamination. This research explores the integration of advanced biodegradable polymer coatings with solar-powered textile waste treatment to reduce microplastic pollution in urban runoff systems. Biodegradable polymers, such as polylactic acid (PLA) and polyhydroxyalkanoates (PHA), are highlighted for their potential to efficiently filter microplastics while providing an eco-friendly alternative to conventional filtration technologies. By combining these materials with a small solar-powered unit, the prototype enables an off-grid, low-energy solution to treat textile wastewater in urban environments. The study includes testing the prototype in simulated urban runoff conditions with varying concentrations of microplastics, evaluating key performance indicators such as microplastic removal efficiency, energy consumption, and operational sustainability. Results demonstrate a significant reduction in microplastic concentration, indicating the effectiveness of biodegradable polymer coatings and solar-powered systems in treating urban runoff. The discussion addresses the feasibility of using local biodegradable materials, performance in real-world urban environments, and operational challenges such as maintenance and scalability. This innovative approach is compared with existing microplastic filtration methods, such as membrane filtration and adsorption, highlighting its advantages in terms of sustainability and cost-effectiveness. The findings suggest that this integrated system could offer a viable, low-cost solution for addressing microplastic pollution in urban drainage systems, with potential for widespread urban implementation.
