Abstract

In the era of globalization, industrial and business activities significantly contribute to environmental impacts, making systematic environmental management crucial. This study analyzes the implementation of an Environmental Management System (EMS) at PT “X” based on ISO 14001:2015, evaluates its performance, and identifies its impact on environmental sustainability. A qualitative approach was employed, with data collected through in-depth interviews, field observations, and document analysis. Informants consisted of five representatives from key functional areas, including top management, accounting, HSES (Health, Safety, Environment & Security), and Quality Assurance as the internal auditor. The interview guidelines were designed according to ISO 14001:2015 clauses to ensure comprehensive coverage. The findings indicate strong top management commitment in supporting EMS implementation through policies that encompass planning, execution, and monitoring. The organizational structure effectively facilitates the environmental management cycle, including identifying, addressing, and resolving findings categorized as major non-conformities, minor non-conformities, and opportunities for improvement. These serve as the basis for performance evaluation and continuous improvement. In conclusion, PT “X” has effectively implemented EMS in line with ISO 14001:2015 and complies with Indonesia’s Law No. 32/2009 on Environmental Protection and Management. The company demonstrates environmental responsibility, and continuous improvement is recommended to strengthen sustainability and stakeholder trust.

Abstract

Savonius wind turbines are wind turbines that canoperate at low wind speeds, this type of turbine is very suitable tobe used in several places in Indonesia. The research aims toimprove the performance of the Savonius wind turbine withvariations in the number of turbine blades as well as variations inthe velocity of wind speed. The research method wasexperimental where wind turbine testing was carried out withvariations in the number of turbine blades with number of 2, 3and 4 blades, other variations carried out were wind speed at 3.5;4,5; 5.5 and 6.5 m/s. The study results show that the 2-bladeturbine produces greater rotation, but the torque moment islower than the 3 and 4 blade turbines, this can be seen in the lowefficiency of the 2 blade turbine at low wind speeds with highloading. At 3.5 m / s wind turbines 2 blade turbines haveefficiency that tends to be the same as 3 and 4 blade turbines upto 0.5 N but at loads of 0.6 - 1.2 N 2 blade turbines have lowerefficiency, while at wind speeds of 4.5 - 6.5 m / s 2 blade turbineshave greater efficiency than turbines 3 and 4 blades up to a loadof 1.2 N but if the load is added then the efficiency of 2-bladeturbines can be smaller than efficiency 3 and 4-blade.

Abstract

Savonius wind turbine is one of the wind turbines that is more widely used for low energy needs, with more energy needs, this turbine type is very feasible to be developed. This research aims to improve the performance of Savonius wind turbines with variations in turbine blade curvature and variations in wind speed. The research method is a laboratory experiment on the fan test, the blade curvature test variation is 1R; 1.5R and 2R, another variation is the wind speed which are 4.0; 5.5; 7.0 and 8.5 m/s. The experiement results shows that the greater the wind speed, the input power, air mass flow velocity, power output, and efficiency will be even greater; the greater the load force on the turbine shaft, the torque on the turbine shaft will also be greater; the relationship of force loads to power output and turbine efficiency is to construct a parabolic curve; for the same wind speed, the 2R turbine has the lowest rotation, power output and efficiency compared to the 1R and 1.5R turbines; at the same wind speed the 1R turbine produces a higher rotation but requires lower torque than the 1.5R turbine; at low wind speeds (4 m / s) the 1.5R turbine has better efficiency than the 1R turbine, whereas at the high wind speed (8.5 m/s) the 1R turbine has a better efficiency than the 1.5R turbine; The maximum efficiency is obtained at 89.56% in the 1R curvature turbine with a wind speed of 8.5 m / s.
