PT EQY is a textile company, especially yarn spinning. The activities of the staffing/packing department at PT EQY are packing, lifting, and moving cardboard boxes. This activity still relies on human power or manual material handling. This work is carried out repeatedly and continuously, causing complaints of pain in several parts of the body during work. This raises the risk of work postures such as Musculoskeletal disorders (MSDs). This research aims to produce a design for work aids that can reduce the risk of Musculoskeletal disorders (MSDs) using the Ovako Work Analysis System (OWAS) method. Based on the problem, work posture analysis was carried out using the OWAS method to find out whether the work posture of staffing/packing employees falls into the risky posture category or not. Based on the results of the Ovako Work Analysis System (OWAS) analysis research, it shows that the posture of staffing/packing workers is included in the high risk category and needs immediate improvement. This improvement involves designing work facilities, namely a handlift and packing table with an ergonomics approach, resulting in a handlift design with a height of 200 cm (2000 mm) and a packing table with a width of 200 cm (2000 mm) and a packing table with a length of 60 cm (600mm), width 60 cm(600mm), and height 104 cm(1040mm).
 
 
 

To support green energy and reduce the effects of greenhouse gases, it is necessary to conceptualize and explore the use of renewable energy. In this research, the use of new renewable energy, especially photovoltaics (PV), will be applied to educational buildings, especially at ITS PKU Muhammadiyah Surakarta. This system is intended to reduce the use of conventional electrical energy. This system will be installed on the roofs of campus buildings with installation plans to meet the power requirement of 4.8 kW. This photovoltaic (PV) system will be modeled to determine the number of PV panels needed. Based on the simulation results, the number of panels required is 36 panels (2 series, 18 parallel) to produce 4.85kWh of power. Modeling and analysis of this system was carried out using RETScreen and MATLAB SIMULINK software.

Radio is a mass media that is still used by many people as a means of communication, such as listening to songs, informing news and others. One of the radio stations that still exists and is developing to this day is Radio Republik Indonesia, which is overseen by the government, which can now be accessed via available radio and websites so that it makes it easier for listeners to listen to and watch the news and can be accessed anywhere. The author conducted research at Radio Republik Indonesia in the Central Jakarta section using qualitative research methods where the author went directly to the field or observed and interviewed as well as assisting with literature studies. The aim of conducting this research was to find out how the broadcasting system and radio supporting equipment at Radio Republik Indonesia Jakarta . So the results obtained are in the form of a radio broadcasting system at Radio Republik Indonesia using two broadcasting systems, namely audio and visual as well as supporting equipment used in the form of Microphones, Mixers, OB – Van, MCR, Transmitter, STL and Antenna.
