HONDE Water Quality Dissolved Oxygen Sensors in Indonesian Aquaculture

Abstract
This case study explores the successful application of Chinese HONDE dissolved oxygen sensors in Indonesian aquaculture. Through the deployment of advanced dissolved oxygen monitoring technology, Indonesian aquaculture enterprises have achieved precise monitoring and intelligent regulation of dissolved oxygen content in farming water, significantly improving breeding efficiency and environmental sustainability.

1. Project Background
As an important aquaculture country in Southeast Asia, Indonesia’s aquaculture industry faces the following challenges:

• Inadequate dissolved oxygen management: Traditional farming relies on manual experience to judge dissolved oxygen status, lacking precise data support
• High breeding risks: Insufficient dissolved oxygen leads to increased stress response in fish and higher disease incidence
• Unstable production: Dissolved oxygen fluctuations affect feed conversion rates, causing significant production volatility
• High energy costs: Lack of intelligent control for aeration equipment operation results in energy waste

2. Technical Solution: HONDE Dissolved Oxygen Sensors
After comprehensive comparison, Indonesian aquaculture enterprises selected HONDE’s DO-500 series dissolved oxygen sensors as the solution.

Product Advantages:

1. High-precision measurement: Advanced optical measurement principle with accuracy of ±0.1mg/L
2. Maintenance-free design: No need to replace electrolytes or membrane caps, reducing maintenance costs
3. Strong anti-fouling capability: Special surface treatment technology effectively prevents biological adhesion
4. Long-life probe: Designed service life of up to 3 years
5. Multiple output interfaces: Support for 4-20mA, RS485, and other output methods

3. Implementation and Deployment
System Configuration:

• Deployment of 2 HONDE dissolved oxygen sensors in each farming pond
• Equipped with intelligent control cabinets integrating data acquisition and equipment control functions
• Establishment of cloud platform for remote monitoring and data analysis
• Mobile APP configuration for convenient real-time data viewing by breeding staff

Optimal Installation Positions:

• Surface sensor: At 0.5m depth, monitoring surface dissolved oxygen status
• Bottom sensor: 0.3m above pond bottom, monitoring bottom dissolved oxygen changes
• Monitoring points at both water inlet and outlet

4. Application Results
4.1 Breeding Efficiency Improvement

• Survival rate increase: Dissolved oxygen maintained at optimal range (5-8mg/L), improving fish survival rate by 15%
• Growth acceleration: Stable dissolved oxygen environment increased feed conversion rate by 12%
• Quality improvement: Fish achieved uniform size and significantly improved flesh quality

4.2 Operational Cost Reduction

• Electricity savings: Intelligent control of aeration equipment reduced power consumption by 30%
• Labor costs: Reduced manual testing frequency, saving 50% in labor costs
• Medication costs: Reduced disease incidence decreased medication usage by 40%

5. Intelligent Management System
5.1 Early Warning System

• Tiered alarm mechanism: Set warning value (3mg/L) and danger value (2mg/L)
• Multiple notification methods: SMS, APP push notifications, audible and visual alarms
• Automatic emergency response: Automatic activation of emergency aeration equipment during low oxygen levels

5.2 Data Analysis

• Historical data query: Support data query and export for any time period
• Trend analysis: Automatic generation of dissolved oxygen variation trends
• Reporting function: Regular generation of aquaculture water quality reports

6. Economic Benefit Analysis
Return on Investment Analysis:

• Initial investment: Approximately $800 per farming pond for sensor deployment
• Operational benefits:
  • Yield increase: 150 kg more high-quality fish per mu
  • Cost reduction: $120 savings in electricity and medication costs per mu
  • Quality premium: High-quality fish price increased by $0.5/kg
• Investment payback period: Average 6-8 months

7. User Feedback
Farm Owner Evaluation:

• “HONDE sensors help us achieve precise oxygenation, we no longer need to check the ponds in the middle of the night”
• “Accurate data, accessible anytime via mobile phone, making management particularly convenient”
• “Fewer fish diseases, higher production, significantly improved benefits”

Technician Feedback:

• “Simple installation, easy maintenance, very suitable for our farm use”
• “The alarm function is very practical, enabling immediate response when problems occur”

8. Promotion Value
Technical Adaptability:

• Suitable for farms of various scales: From family farming to large enterprises
• Compatible with multiple breeding species: Fish, shrimp, shellfish, etc.
• Withstands environmental challenges: Corrosion resistance, anti-biofouling

Social Benefits:

• Promotes modernization and transformation of aquaculture industry
• Enhances water product quality and safety levels
• Reduces environmental pollution risks from aquaculture
• Increases economic income for farmers

9. Conclusion and Outlook
The successful application of HONDE dissolved oxygen sensors in Indonesian aquaculture demonstrates:

1. Technical leadership: Optical measurement technology suitable for aquaculture environments, providing accurate and reliable data
2. Economic practicality: High return on investment, suitable for widespread adoption
3. Management intelligence: Enables refined management and improves aquaculture standards

Future Plans:

1. Establish regional water quality monitoring networks
2. Develop multi-parameter integrated monitoring systems
