Indonesia Shrimp Farm Monitoring Case

Indonesia is a major white-shrimp producer, and intensive ponds suffer frequent night-time hypoxia. Kantangren (SAFEBACK) DO + temperature + 4G + VFD aeration linkage replaces night patrol with dissolved-oxygen watch, turning night duty into system duty.

Background: intensive shrimp, frequent night hypoxia

Indonesian white-shrimp farming is mostly intensive earthen and raceway ponds - high density, heavy feeding - where the night-time dissolved-oxygen trough repeatedly dips below the safe line and floaters or even mass loss are common. Farmers used to walk the ponds and start aerators by feel, often acting only once they saw floaters - by which point DO was already at the bottom. This is typical of tropical round-the-clock farming: strong light, swingy algal blooms, and a very steep day-night DO swing.

Deployment: DO + temperature + 4G + VFD aeration linkage

The retrofit followed Kantangren (SAFEBACK) standard architecture: a fluorescence DO sensor and temperature probe connect over RS485 to a 4G controller, data goes to the cloud, and the platform drives aerator speed through a VFD by each pond's thresholds. The core swap is from 'watched by a person' to 'watched by dissolved oxygen' - DO below the warning line speeds the aerators up, recovery slows them down, and data caches locally on network loss. Multiple ponds share one dashboard, alerts escalate by pond to the phone, and night patrol is no longer manual.

Results: fewer hypoxia incidents, less chemical use

The gain is not a single headline number but a change in how the farm runs: with nobody on night duty, aerators start and stop on the DO curve, and floater and mass-loss incidents dropped markedly versus before. Steadier DO also cuts stress and secondary infection, so water-conditioning and chemical use fall too. Results depend on density, equipment power and operating strategy - these are project-level records, not a universal promise. To the farmer the most tangible change is 'no more getting up at 3 a.m. to start the aerators.'

What transfers to other farms

The playbook copies to similar tropical intensive shrimp ponds: survey pond count, area, depth, density and 4G coverage first, then set thresholds per pond; a starter kit covers a single pond, a large farm manages many from one screen. Kantangren (SAFEBACK) runs a partner service network across Southeast Asia for install and after-sales. The key is not piling on hardware but standing up 'DO linkage + remote alert' as baseline capability first.

FAQ

Is it suitable for small farms?

Yes. It scales with farm size; a starter kit covers a single pond, and it pays off once density and stock value are high enough.

Is local support available?

Kantangren (SAFEBACK) has a partner service network across Southeast Asia covering install and after-sales.
