Below is a concise, practical overview of smart greenhouse automation systems in Indonesia — market players, technology options, what to budget for, key design considerations, and recommended next steps.

1. Who’s offering systems in/for Indonesia (examples)

• Local telco / IoT platform offerings: XL Axiata launched “XL Smart Hydroponics” — an all‑in‑one IoT hydroponics/greenhouse solution (sensors, actuators, platform) and has implemented pilots in West Java. (xlaxiata.co.id)
• Local system integrators / IoT developers: Indonesian engineering/IoT firms and startups provide turnkey greenhouse automation and custom IoT solutions (examples of local firms offering Hortimod/OS-based or bespoke systems). See Indonesian integrator portfolios for modular systems (sensors, fertigation, dashboards). (Ditstek.com)
• International greenhouse/control vendors: Global greenhouse automation leaders (e.g., Priva and other Dutch/European suppliers) sell climate control, fertigation and SCADA-style platforms and often work with local partners or distributors for installation and service. (en.Wikipedia.org)
• Research / DIY / low‑cost solutions: Indonesian universities and researchers publish IoT greenhouse prototypes using Arduino/Wemos/Raspberry Pi (temp/humidity, soil moisture, pH, water level) — good for small farms, demos, or low‑budget pilots. (JEMIT.fmipa.unila.ac.id)

2. Typical system components

• Sensors: air temperature, relative humidity, CO2, light (PAR/PPFD), soil/substrate moisture, EC/TDS and pH (fertigation), water level, rain/wind (for unprotected sites).
• Actuators: vents, fans, heaters, foggers/humidifiers, shading screens, irrigation pumps, fertigation injectors, grow lights.
• Control & automation: PLCs / microcontrollers or industrial controllers, PID loops or recipe-based controllers, alarm rules, scheduling.
• Connectivity & platform: local gateways (LoRaWAN, NB‑IoT, Wi‑Fi, cellular), cloud dashboards, data storage, analytics/ML for crop recipes.
• Power & backup: grid, generator, or solar + battery for remote sites.
• Services: installation, calibration, crop‑recipe setup, maintenance and spare parts.

3. Deployment options & pros/cons

• Turnkey commercial systems (international/local vendors): fastest and most reliable for commercial scale, include support and warranties; higher CAPEX; may require local partner for service. (en.Wikipedia.org)
• Modular/local integrator builds: mid CAPEX, customizable, better local support and pricing; depends on integrator quality. (Ditstek.com)
• DIY/academic/low-cost IoT kits: lowest cost and good for prototyping, education, and small urban farms; limited reliability and scaling. (JEMIT.fmipa.unila.ac.id)

4. Key technical and business considerations for Indonesia

• Climate & crop: tropical humidity/temperature profiles affect ventilation, cooling and disease control; choose crop recipes and climate control appropriate for local conditions.
• Connectivity: choose communication tech based on site (urban vs rural) — cellular or LoRaWAN are common in Indonesia. Telco IoT platforms (e.g., XL flexIoT) can help. (xlaxiata.co.id)
• Water & fertigation: monitor EC/pH closely; automation reduces nutrient errors and improves yields.
• Energy: cooling/ventilation can be the biggest operational cost in tropical greenhouses — evaluate passive cooling, shading and energy-efficient equipment.
• Local service & spare parts: prioritize vendors or integrators with local presence or partners for fast maintenance.
• Data & recipes: value comes from data — logging, analytics and iterative crop‑recipe tuning increase yield and reduce inputs over time.
• Regulations & incentives: check local/regional incentives for ag-tech, renewable energy, or MSME programs if financing is needed.

5. Ballpark costs (very approximate)

• Small hobby/urban (DIY kit + cloud monitoring): USD 300–2,000. (JEMIT.fmipa.unila.ac.id)
• Commercial small greenhouse (modular automation, sensors + basic actuators): USD 5,000–30,000 depending on size and automation level.
• Commercial/industrial turnkey (complete climate control, fertigation, lighting, SCADA): tens of thousands up to hundreds of thousands USD for large facilities; international suppliers + installation increase cost but add robustness and support. (Costs vary widely — get quotes.)

6. How to choose a supplier / evaluation checklist

• Local references and on‑the‑ground installations in Indonesia.
• Service level: response time, spare parts, training.
• Openness & integration: APIs, data export, standard protocols (Modbus, MQTT).
• Crop recipes & agronomy support (not just hardware).
• Scalability: can the system grow with your farm?
• Total cost of ownership: energy, consumables, maintenance.

7. Quick next steps (practical)

• Define objectives: target crop(s), area (m2), target yield, budget, and whether retrofit or new build.
• Pilot first: start with a small pilot (one greenhouse or one growing bay) to validate crop recipes and automation. University or integrator pilot projects can reduce risk. (JEMIT.fmipa.unila.ac.id)
• Shortlist suppliers: ask for local references, service contracts, and a demo of the dashboard and data export. Include at least one local integrator and one established international vendor for comparison. (en.Wikipedia.org)
• Consider telco/IoT platforms if you need managed connectivity/IoT platform services (e.g., XL’s smart hydroponics offering for IoT + platform). (xlaxiata.co.id)

8. Useful resources & places to look

• XL Axiata IoT / “XL Smart Hydroponics” for managed IoT solutions and pilots. (xlaxiata.co.id)
• Local integrator portfolios and Indonesian agtech/startup showcases (search for greenhouse automation, horti‑IoT or “smart greenhouse Indonesia”). (Ditstek.com)
• Academic papers from Indonesian universities on IoT greenhouse prototypes for low‑cost sensor/automation ideas and research partners. (JEMIT.fmipa.unila.ac.id)
• International greenhouse vendors (Priva and peers) for industrial commercial solutions; ask about Indonesian distributors/partners. (en.Wikipedia.org)

If you want, I can:

• shortlist Indonesian integrators and contact links (I can look up current vendors and partners), or
• prepare a one‑page request for proposal (RFP) template you can send to vendors asking for quotes, or
• design a simple sensor/actuator list and estimated BOM for a specific greenhouse size (specify m² and crop).

Which of those would help you next?
