Mertani Automatic Rainfall Recorder (ARR) in Plantations

Mertani Automatic Rainfall Recorder (ARR) will assist you in measuring rainfall from anywhere and anytime. ARR will help you obtain more accurate rainfall data, improve farm water management, and enhance fertilizer absorption efficiency.

Challenge

  • Indonesia, with its diverse regions characterized by high rainfall, faces limitations in the number of rain gauge stations. As a result, rainfall data becomes uneven and difficult to predict. This situation highlights the importance of enhancing infrastructure for more accurate weather measurements.

  • The use of ARR devices is supported by various government regulations and policies related to environmental management and disaster mitigation. This is reflected in various laws and government regulations governing the use of technology for environmental measurement and monitoring, including rainfall.

Study Case

Study Case

Implementation of Automatic Rainfall Recorder (ARR) at Oil Palm Plantation Sites in East Kalimantan.

PT Mertani installed Automatic Rainfall Recorders (ARR) at six different locations in oil palm plantations in East Kalimantan. These locations include Kaubun, Berau, Muara Ancalong, Muara Kaman, Muara Bengkal, and Paser.

The purpose of installing ARR devices is to enhance automatic climate monitoring at various points in oil palm plantations. This is expected to assist in making more accurate and efficient operational decisions, as well as increasing productivity and income from the plantations.
