Field Survey

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.

Soil Moisture Survey

GITIIA researcher, Nur Etika Karyati, recently received soil moisture meter PMS710 and gave it a try in some districts around Dramaga and Ciomas, Bogor. She investigated various cash crops, including rice, maize, peanuts, sweet potatoes, chillies and fallow fields. Photo: Etika

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.

Contribution in Asian Conference on Remote Sensing 2020

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.

Fieldwork at Cihea Site

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.

Uncertainties to rice production

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:
