In an effort to encourage sustainable development, the Indonesian Ministry of Environment and Forestry (KLHK) has implemented the PROPER program (Company Performance Rating Assessment Program in Environmental Management). The highest ratings in this program are gold and green, where the green rating is given to companies that have exceeded minimum compliance with environmental regulations, as well as demonstrated innovative initiatives in natural resource management and pollution reduction.
One technological approach that can support the achievement of a green rating in PROPER is the implementation of Electrical Signature Analysis (ESA) in the company's operational activities.
What is Electrical Signature Analysis (ESA)?
Electrical Signature Analysis is a non-invasive condition monitoring method used to detect the condition of electric motors and other electro-mechanical systems through electrical signals such as current and voltage. Electrical Signature Analysis enables early detection of disturbances in industrial equipment such as induction motors, pumps, compressors, and gearboxes, without having to dismantle the equipment.
The Relation of Electrical Signature Analysis to PROPER Green Rating
The implementation of Electrical Signature Analysis has a real contribution to the PROPER assessment criteria, especially in terms of energy efficiency, emission reduction, and environmentally friendly innovative practices. Here are some of the connections:
1. Energy Efficiency
Electrical Signature Analysis helps companies identify energy-wasting equipment due to hidden damage such as phase imbalance, harmonics, or mechanical damage. With targeted repairs, companies can reduce electricity consumption, which has a direct impact on reducing carbon footprints.
2. Predictive Maintenance with Minimal Waste
Compared to reactive maintenance methods, Electrical Signature Analysis allows maintenance to be carried out only when needed, reducing waste of lubricants, spare parts, and other hazardous materials. This is in accordance with the reduce-reuse-recycle principle which is highly appreciated in PROPER.
3. Innovation in Environmental Management
The use of Electrical Signature Analysis can be included in the category of beyond compliance initiatives in PROPER because the technology is not required by regulation, but has a positive impact on the environment and industrial process efficiency.
4. Reducing the Risk of Operational Disruption
Production disruption due to machine damage can result in waste overflow, uncontrolled emissions, and low efficiency. Electrical Signature Anaylsis helps prevent this with continuous monitoring, making operations more stable and environmentally friendly.
Case Study Example
A palm oil processing company implemented Electrical Signature Analysis on screw press and pump drive motors. The Electrical Signature Analysis results showed indications of damaged bearings and unbalanced loads. With timely repairs, the company managed to reduce electricity consumption by 8% and reduce downtime by 60% in one year. This is an added value in PROPER reporting, especially in the efficiency and innovation categories.
Electrical Signature Analysis is not only a technical tool for maintenance, but can also be part of a company's strategy to achieve environmental sustainability. With good documentation, the results of Electrical Signature Analysis implementation can be one of the real evidences in the beyond compliance efforts needed to obtain a green rating in PROPER. Through a smart and technology-based approach like this, companies not only improve operational efficiency and reliability, but also demonstrate a strong commitment to responsible environmental management.
Currently, PT Hyprowira Adhitama is a provider of Electrical Signature Analysis in Indonesia, as well as being a distributor of Enging in Indonesia.
