Water quality monitoring is one of the most crucial tasks in modern pond cultivation. Small changes in parameters such as ammonia, dissolved oxygen (DO), alkalinity, and nitrite often occur rapidly without easily recognizable visual symptoms. When detection is delayed, the impact can directly impact cultivation performance, ranging from decreased appetite, slowed growth, impaired molting, to an increased risk of disease.

However, in the field, water quality monitoring remains a challenge for many pond technicians. In addition to the limited availability of practical tools, the process of interpreting monitoring results often depends on the technician's individual experience.

To address these challenges, FisTx officially launched the NAWASENA Water Test Kit, a pond water quality monitoring solution designed to be easier to use, more economical, and equipped with a superior 24/7 Smart Virtual Assistant feature to assist technicians in understanding monitoring results and determining necessary technical actions.

FisTx CEO, Rico Wisnu Wibisono, explained that this innovation was developed to address the needs of pond technicians who require a practical monitoring tool and analytical assistance that can be accessed at any time.

"In the field, the challenge isn't just conducting water quality tests, but also how to quickly interpret the results and determine the appropriate action. That's why we've equipped NAWASENA with a Smart Virtual Assistant so technicians not only receive test results but also real-time technical assistance," he said.

Quick Monitoring Directly at the Pond

The NAWASENA Water Test Kit allows technicians to test important parameters such as:

• Ammonia (NH3/NH4)
• Nitrite (NO2)
• Alkalinity
• Dissolved Oxygen (DO)
• pH
• Calcium (Ca)
• Magnesium (Mg)
• Other supporting water quality parameters

Users simply take a pond water sample, add reagents or test strips, and then match the color change with the color chart provided in the kit.

The entire process can be performed directly in the field without additional equipment, and results can be obtained in real time within 1–2 minutes.

This speed allows technicians to make immediate operational decisions such as:

• Increasing aeration when DO decreases
• Adjusting feeding when signs of stress appear
• Mineralizing
• Anticipating ammonia spikes
• Evaluating the effectiveness of water quality treatments

With testing costs around IDR 1,500–IDR 1,900 per test, routine monitoring is much more feasible than laboratory methods or high-investment digital devices.

Smart Virtual Assistant 24/7: A Technical Assistant at Your Fingertips

NAWASENA's most prominent feature is the Smart Virtual Assistant, an exclusive service that all customers can access free of charge, 24/7, via their smartphones. After purchasing, customers gain immediate access to this feature at any time.

Through the Smart Virtual Assistant, technicians can:

• Consult regarding water quality monitoring results
• Understand the meaning of parameter changes more precisely
• Receive technical action recommendations based on modern aquaculture SOPs
• Analyze pond conditions based on test data
• Receive technical assistance whenever needed

This approach provides a new experience in water quality monitoring, as users no longer have to work alone when interpreting field data. Whereas previously, interpreting test results relied heavily on the experience of senior technicians or time-consuming manual consultations, now the entire analysis process can be done more quickly directly from a mobile device.

Not Just a Test Kit, but a Decision-Making System

According to Rico, NAWASENA was developed not just as a water quality measurement tool, but as a data-driven aquaculture decision support system. "We want water quality monitoring to be a simple, consistent, and actionable daily activity. With the combination of the test kit and the Smart Virtual Assistant, technicians can be more confident in making decisions, supported by fast and accurate data interpretation," he explained. This innovation is also part of FisTx's efforts to drive the transformation of Indonesian aquaculture towards a more preventative, precise, and sustainable system. As an Indonesian product, NAWASENA offers a local solution with international standards, specifically designed to meet the real needs of Indonesian aquaculture farmers. The NAWASENA Water Test Kit is currently available nationwide through FisTx's official channels, official marketplaces, and the company's sales team. For more information, visit: FisTx Indonesia
