Mangrove Health Tester: Inovasi Pendeteksi Kesehatan Mangrove Berbasis Arduino Sebagai Langkah Awal Mitigasi Bencana Tsunami Di Kota Palu, Sulawesi Tengah

Mangrove has important role in ecosystem. However, the existence of the mangrove
ecosystem is experiencing disruption, which affects the existence of mangroves. It is important
to know the health of mangroves to determine further conservation steps. The research method
by purposive random sampling to choose tree of mangrove and measure environmental factor
like water salinity, pH levels and HUE values of leafs using the innovation of the mangrove
health tester tool that take into account the size including large stem diameter, tree height, and
the light intensity. The species of mangrove’s will taken to measurement in Rhyzophora spp.
We take 5 location of mangrove ecosystem as our sample, for location 1 R=22.40 G=20.48
B=19.98 salinity=27.7‰ pH=7.16, location 2 R=17.52 G=15.95 B=16.15
salinity=29.71 pH=7.35, location 3 R=18.60 G=17 B=17.03 salinity=29.40‰ pH=7.93,
location 4 R=21.33 G=19.17 B=19.02 salinity=28.75‰ pH=8.04, location 5 R=25.48
G=23.25 B=21.56 salinity=0‰ pH=8.04. Therefore, the salinity and pH levels effects the
RGB levels of Mangrove leaves as shown in 5th location. The results of measurements of
salinity, pH levels and RGB values of leaves linked as a result of generalizing analysis of
healthy mangroves.
