Geolini is designed for monitoring tectonic, volcanic, and microseismic activity, as well as induced seismicity, making it suitable for researchers, disaster-monitoring institutions, and industrial applications.

The innovation, developed by Dr. Ir. Zulfakriza, S.Si., M.T. and Prof. Dr.Sc. Ir. Andri Dian Nugraha, S.Si., M.Si., was created to reduce Indonesia’s dependence on imported earthquake-monitoring instruments.

Following continuous development since 2020, Geolini has now reached Version 2, which is capable of transmitting data wirelessly for remote, real-time monitoring.

Its reliability has been tested against industry-standard instruments. It has also been deployed in geothermal fields and oil and gas exploration activities and is now being marketed through the Ganesa Connection platform.

The development represents a step toward greater national self-reliance in geophysical instrumentation technology, which is particularly important for Indonesia given its high levels of seismic and volcanic activity.

“We have long relied on products from overseas. Therefore, we are trying to develop a domestically made seismometer to support technological self-reliance,” said Dr. Zulfakriza, as quoted from the DRI YouTube channel on Monday (24/8/2026).

The project was initiated in 2020 during the COVID-19 pandemic and has now entered its fifth year of development. Prof. Andri Dian Nugraha said the research began with a simple prototype and is now being directed toward broader-scale production.

The name Geolini is an acronym that embodies the philosophy of Seismograf Ganesa untuk Bangsa (“Ganesa Seismograph for the Nation”). It combines the word Geo, referring to the Earth, with lini, a Sundanese word meaning earthquake.

Lightweight and Flexible for Field Deployment

Based on its technical specifications, Geolini was designed as an ultra-lightweight, three-component digital seismometer. Its lightweight construction and portable design allow it to be installed quickly, even by a single person, at locations with moderate levels of ambient noise.

In addition to being practical, Geolini features a waterproof body with O-ring seals protecting various parts of the device, enabling it to operate under a range of environmental conditions.

The instrument can be used for local seismic and microseismic monitoring, including tectonic and volcanic activity as well as induced seismicity. It can also be applied to monitor seismic activity associated with hydraulic fracturing and other applications requiring high resolution and a wide dynamic range.

Geolini Version 2 Integrates IoT Technology

Geolini has currently reached Version 2 (V.2). While the previous version still relied on physical cable connections, Geolini V.2 uses a wireless system supported by IoT technology. This enables data to be monitored remotely in real time.

As a result, observation data no longer need to be retrieved directly from the devices deployed in the field. This remote data-transmission capability can improve monitoring efficiency, particularly when instruments are installed in difficult-to-access locations.

Capable of Recording Earthquakes Thousands of Kilometers Away

Geolini’s reliability has been tested comparatively at the ITB Jatinangor Campus Seismograph Station by operating it alongside standard instruments commonly used in the industry.

During the tests, Geolini successfully recorded regional seismic waves from a magnitude 5.4 earthquake in Pelabuhan Ratu, as well as a magnitude 6.2 teleseismic earthquake south of Mindanao, the Philippines, located thousands of kilometers from the instrument.

“The consistency of the post-earthquake recordings shows that the instrument we developed, Geolini, consistently records both P-wave (Primary) and S-wave (Secondary) phases, with performance comparable to foreign-brand instruments,” Dr. Zulfakriza said.

Geolini has also been deployed for three months in a geothermal field and used in oil and gas exploration activities in Kalimantan. These field deployments have played an important role in testing the device’s durability and recording consistency under different operational conditions.

Toward Commercialization and Self-Reliance in Geophysical Instrumentation

As part of its commercialization process, Geolini is now being marketed through Ganesa Connection, ITB’s digital marketplace platform. This step is intended to ensure that the research does not stop at the prototype stage, but can be adopted more widely for research purposes and field applications.
