PROJECT PORTFOLIO
Proven Track Record in Industrial Solutions
A collection of successful case studies demonstrating PT Global Persada Teknologi (neXus)'s expertise in automation, SCADA, IIoT telemetry, and energy management across leading manufacturing facilities.
Industrial Automation
Real-time Process Data Monitoring
Mixing & Filling Line Automation with Real-Time Process Data Monitoring
The production area has two lines, the mixing line and the filling line. Both lines are automated and monitored in real-time through a centralized SCADA engine.
Real-time process data from both mixing and filling lines is now centrally monitored through a single SCADA dashboard.
Machine status (run/stop) and critical process parameters (temperature, pressure, fill volume) are visualized in real time.
Key Results:
Real-time Process Data Monitoring
Challenge
The main challenge was to integrate existing data from filling machines using Mitsubishi PLCs and Weintek HMIs, together with Ystral panels equipped with Siemens PLCs in a hazardous area, into a unified monitoring system without disrupting existing machine operations.
Solution
The neXus team implemented a distributed monitoring architecture using neXus SCADA and industrial Ethernet switches to connect to the existing control system. This solution allowed real-time process data to be collected from both mixing and filling machines without requiring a complete overhaul of the existing PLC infrastructure.
Measurable Results
- Real-time process data from both mixing and filling lines is now centrally monitored through a single SCADA dashboard.
- Machine status (run/stop) and critical process parameters (temperature, pressure, fill volume) are visualized in real time.
- Historical data logging and reporting capabilities enable production analysis and troubleshooting.
- The monitoring system can be expanded to include additional machines and process steps in the future.

SCADA & Monitoring
Real-time Data Monitoring & Fast Anomaly Response
Web SCADA & Distributed Telemetry for Reservoir and Waste Water Treatment Plant (WWTP)
A centralized web-based SCADA and telemetry system for real-time monitoring of reservoir levels, flow rates, pH, TDS, and turbidity across distributed water treatment facilities.
Operators can monitor real-time changes in flow rate, totalizer, level, pH, TDS, and turbidity sensor readings.
Real-time Telegram notifications for reservoir levels and pump status (ON, OFF, or TRIP), enabling immediate field inspection when abnormal conditions occur.
Key Results:
Real-time Data Monitoring & Fast Anomaly Response
Challenge
The water reservoirs and wastewater treatment plant were located far from the central control room, requiring operators to travel between sites using operational vehicles to collect process readings manually. This resulted in limited real-time visibility and delayed response to abnormal operating conditions.
Solution
The neXus team implemented industrial-grade Remote Terminal Units (RTUs) with secure cellular VPN connectivity, integrated with ultrasonic level sensors, electromagnetic flowmeters, pH, TDS, and turbidity sensors. Field data was transmitted through MQTT and centrally visualized using the ThingsBoard platform, enabling secure remote monitoring across distributed sites.
Measurable Results
- Operators can monitor real-time changes in flow rate, totalizer, level, pH, TDS, and turbidity sensor readings.
- Real-time Telegram notifications for reservoir levels and pump status (ON, OFF, or TRIP), enabling immediate field inspection when abnormal conditions occur.
- Field operators can securely monitor equipment status and sensor data directly from tablets and mobile devices

Real-Time Monitoring & Fast Anomaly Response
Reservoir Level and Pump Status Monitoring
A centralized web-based monitoring system for real-time reservoir levels and pump status across multiple remote locations.
Operators can monitor real-time reservoir levels and pump status, including On, Off, and Trip conditions.
Reduced the risk of reservoir overflow by implementing automatic pump shutdown when the water level reaches a critical limit.
Key Results:
Real-Time Monitoring & Fast Anomaly Response
Challenge
The system is deployed across four geographically dispersed locations: Siwarak, Tambakboyo, Senjoyo, and Ngemplak. Reliable remote monitoring and secure data connectivity were required to provide centralized visibility of reservoir conditions and pump operations.
Solution
The solution integrates industrial-grade Remote Terminal Units (RTUs), encrypted cellular VPN connectivity, ultrasonic level sensors, and pump motor status monitoring. Data from all remote stations is transmitted to a centralized monitoring platform powered by Grafana, enabling operators to monitor field conditions in real time.
Measurable Results
- Operators can monitor real-time reservoir levels and pump status, including On, Off, and Trip conditions.
- Reduced the risk of reservoir overflow by implementing automatic pump shutdown when the water level reaches a critical limit.
- Field operators can securely monitor equipment status and sensor data from tablets and mobile devices.
- Reduced the need for manual operator patrols to remote locations.

Key Results:
Real-time Gas Stove Monitoring, Data Logging & Calibration
Challenge
Gas stove testing required continuous monitoring of multiple test stations with accurate temperature and pressure measurements. Manual recording of test results made it difficult to maintain consistent test data, monitor operating conditions in real time, and perform efficient calibration and reporting.
Solution
Development of a dedicated SCADA application integrated with a PLC through Modbus TCP. The system simultaneously monitors up to five gas stove testing stations, displaying real-time temperature and pressure data, configurable temperature set points, gas solenoid valve control, pressure mode selection, zero/span calibration, and automatic data logging. Historical test data can be searched, visualized through trend charts, and exported to Excel and PDF reports.
