GITIIA has attended SATREPS Flood Team online meeting in 23 December 2020. This marked our end-of-year research activity, together with a LPDP supported field work (24-28 December 2020). With the amount of dataset available to the team, we seek to submit several manuscripts at international levels…
Interns Ms. Arda Ardella and Fiktia Alfianita, assisted by Mr. Ramadhani Dwi Handrian conducted a field survey to collect ground data for their research in remote sensing applications in rice fields. Measurements included soil moisture, chlorophyll and growth stages to help building estimation models from Sentinel-1 data.

In a near future, we plan a publication using the dataset with the topic of soil moisture estimation using Sentinel-1 SAR data that overpassed in that day.
A new book chapter, contributed by Dyah Panuju and Bambang Trisasongko, has been published in collaboration with senior lecturers from The University of New South Wales, Canberra and RMIT University, Melbourne, Australia. It focuses on the use of satellite imageries in the monitoring rice growth stages. Details available in Springer website.
Research intern, Mr. Muhammad Hayyu Mahabbah, has recently received notification on the acceptance of his abstract in ACRS 2020; this year is virtually managed by China. His contribution title is “Rice Field Detection and Mapping Using Multitemporal Sentinel-1 Synthetic Aperture Radar Data with RGB Composite and Thresholding Approach: A Case in Three Districts of Cianjur, Indonesia” with Baba Barus and Bambang Trisasongko as co-authors.
In addition to Cihea site, IPB Team led by Dr. Boedi Tjahjono, DEA have investigated the inundation event during January 2020. The team included two undergraduate students researching flooding and microtopography from UAV’s Structure from Motion (SfM).
In the final week of January, SATREPS-IPB teamed up with Dinas Tanaman Pangan dan Hortikultura, Provinsi Jawa Barat to collect ground data in Cihea region. We found that rice paddies are still in early planting rotation. Dinas has introduced two rice cultivars, i.e. Pajajaran and Siliwangi. Needless to say, this new introduction only cover few parcels. However, we keen to investigate more in their growth in the future.
The IPB team was led by Dr. Khursatul Munibah, M.Sc. assisted by Dr. Boedi Tjahjono, DEA, Dr. M. Ardiansyah, La Ode S. Iman, MSi and Bambang Trisasongko, PhD along with 12 undergraduate students.
In general, rice production in Indonesia has two major threats: geohazard and anthropogenic causes. Geohazards have long been studied, including inundation, drought, etc. On the other side of the story, man-related threats need more attentions, not merely science-based but policy making would contribute to the production.
Our previous research tells us that infrastructure development can cause vulnerability to the existence of rice fields. Details are presented in:

A new version of Inundation Monitoring Using Sentinel-1 is available in Bahasa Indonesia.
