Here are smart‑greenhouse suppliers and integrators in Indonesia (websites or news showing their smart/IoT greenhouse work). I’ve included a short note on each and a source you can check.

• AgriFam (PT AgriFamili Sarana Exedis Indonesia) — Builds commercial smart greenhouses (climate control, dosing, IoT monitoring, hydroponic systems); project portfolio includes research and commercial installations. (agrifam.co.id)

• Agrosolution — Offers turnkey greenhouse & smart greenhouse technology (hydroponics, climate control, project engineering and installation). (agrosolution.co.id)

• Harja Smart Greenhouse (Harja Smart Green) — Indonesian provider advertising IoT‑based smart greenhouse solutions and customized designs. (harjasmartgreen.com)

• PT Arana Agroteknologi Indonesia (GreenhouseIndonesia.co.id) — Manufacturer/supplier of greenhouse structures and accessories for Indonesian market. (greenhouseindonesia.co.id)

• Agrarise — IoT/precision‑agriculture developer that provides greenhouse climate control (Engrow) and low‑cost/affordable greenhouse solutions for tropical areas. (agrarise.com)

• PT Rasa Agri / Rasa Group (vendor for institutional smart greenhouse projects) — cited as a vendor for smart‑greenhouse installations and knowledge transfer in university/government projects. (unusia.ac.id)

• PT Agro Jabar / PT Agrindo Karya Persada (project-based) — local companies that have developed/deployed smart greenhouse tech (drip irrigation, fertigation) in West Java (example reported by Antara). (antarafoto.com)

• Research / integration groups (SmartAgri UGM and partners) — university research center and industry collaborations that design/deploy IoT smart‑greenhouse systems (useful if you want research partners or proven system integrators). Recent project examples include deployments with industry partners. (smartagri.tp.ugm.ac.id)

Quick selection checklist (what to ask each supplier)

• Do they provide full turnkey (structure + climate control + fertigation + IoT dashboard) or only parts?
• References / photos of completed installations in Indonesia (similar crop & climate).
• Sensors & control platform: which sensors (temp, RH, CO2, pH, EC), local vs cloud dashboard, data access and API.
• After‑sales & training: commissioning, agronomy support, warranty, spare parts availability locally.
• Scalability & customization: modular sizes, materials (UV film vs polycarbonate), shading/ventilation options.
• Cost estimate and timeline for delivery/installation.

Next practical steps

• Visit each supplier website (links in the citations) and request a site visit / proposal (include expected greenhouse size, crops, and budget).
• Ask for at least 2 local references and technical spec sheets for sensors/controllers.
• If you’d like, I can draft a standard RFQ you can send to 3–5 vendors (including fields for specs, warranty, installation timeline, and training).

Would you like an RFQ template to send to these suppliers (I can tailor it for a specific crop, size, or budget)?
