00:00In the southern waters of East Java, there is hidden a wild ecosystem that is still mysterious to the world of science.

00:10A small island that seems to stand alone in the middle of the ocean,

00:14become the last bastion of untouched biodiversity.

00:20Nusa Barong or Nusa Barong is a small island located south of Java Island.

00:26This island is located in the Puger Kulon Village area, Puger District, Jember Regency, East Java.

00:34Designated as a conservation area since 1920 and designated as one of the outermost islands in Indonesia.

00:45The 7,635 hectare uninhabited island now has the status of a wildlife sanctuary.

00:53Based on the decision of the Minister of Forestry on May 1, 2013.

00:59Today with the help of cutting-edge technologies such as e-DNA, Soundscape, and satellite imagery,

01:07Scientists are beginning to uncover new insights into the island's wildlife.

01:11Nusa Barong Island is a unique mosaic of ecosystems.

01:23The coastal forest is filled with typical vegetation such as

01:26nyamplung tree with scientific name,

01:29kalophylum inofilum,

01:31then put it with the scientific name,

01:33barringtonia espedinum,

01:35and sea pandan or pandanus tectorius.

01:38The existence of mangrove forests surrounding Plirik Bay and Kandangan Bay

01:44is real evidence that the ecosystem on this island is still functioning well.

01:49Here, Rizophora mucronata and Aficenia spi

01:53creating habitat for various species of fish, crabs and water birds.

01:59However, what is most surprising about this latest exploration is that

02:05the existence of a lowland tropical forest ecosystem that is still very beautiful.

02:11Latest research results as of May 2024

02:15from the team from the Center for Applied Zoology Research,

02:19BRIN Biological and Environmental Research Organization

02:21together with the East Java KSDA Center,

02:24Bromo Tengger Semeru National Park Main Office,

02:28Samboja Environmental and Forestry Instrument Standards Implementation Center,

02:32and the Pakarti Foundation,

02:34found indications of the existence of Rafflesia.

02:36One of the rarest parasitic flowers in the world

02:39which lives on the host plant tetrastigma SP.

02:42If confirmed,

02:45this will be an important scientific discovery

02:47which adds important value to the status of the Nusa Barung area

02:50as a conservation area.

02:58But, did you know?

03:01Nusa Barung Island is also home to diverse fauna.

03:05The beach is a regular landing site

03:08for green turtles with scientific names,

03:11Celonia Midas,

03:12who come to lay eggs every year.

03:15Besides that,

03:16rare species such as the hawksbill turtle with the scientific name,

03:20Eretmocellis imbricata,

03:22also found in the waters around this island.

03:28Then in the forest,

03:30camera trap successfully captures documentation

03:33Rusatimor or Rusatimoresis

03:36and long-tailed monkeys,

03:38Macaca fascicularis.

03:40Then the bird survey recorded more than 30 species.

03:44found on this island.

03:46With the species Pachnonotus plumosus

03:49and Schalcovaps indica

03:50as two dominant species that fill

03:53the acoustic landscape of the island.

03:55Then there are also some rare predator species,

03:58starting from the white-bellied sea eagle with the scientific name,

04:01Haliaetus leukogaster,

04:03the bido snake eagle or Spilornis cila,

04:06and the Javan eagle with the scientific name,

04:08Nisaetus bartelsi,

04:10also found circling the skies of Nusa Barung.

04:13This indicates that the food chain on this island

04:15still functioning naturally.

04:19The interesting thing about using bioacoustics

04:22to uncover the hidden life in Nusa Barung.

04:25Sound recording in the depths of the forest

04:28generated over 24 thousand voice annotations

04:31with the majority coming from birds, insects and amphibians.

04:36Soundscape analysis shows that

04:38This island has a high acoustic diversity index,

04:42indicates an environment that is still healthy and rich in species.

04:47In addition, e-DNA technology is applied on this island

04:50also brings a big surprise.

04:52Samples taken from fresh water sources and tree trunks

04:56revealed the existence of 554 species from five kingdoms

05:00such as from Amebozoa, Animalia, Chromalveolata, Fungi, and Plantai.

05:07This includes various species of microbes.

05:08which had never been previously detected on this island.

05:15In the expedition,

05:17Researchers also found 11 species of bats.

05:20All of these are new records for Nusa Barung Island.

05:24One of the most dominant species here

05:26is Rosetus Amplexicaudatus,

05:29fruit-eating bats play an important role

05:32in the distribution of seeds.

05:33Meanwhile,

05:37the herpetofauna survey successfully recorded 19 species of reptiles and amphibians,

05:43including water lizards with scientific names

05:46Pharanus salvator,

05:48gray monitor lizard or Faranus nebulosus,

05:51as well as several species of frogs and lizards

05:54most of which are new records for the island.

05:57This discovery further confirms that Nusa Barung

06:01is an important refuge for fauna

06:03which requires a natural habitat with minimal human disturbance.

06:10Apart from its rich biodiversity,

06:13Nusa Barung Island faces major challenges in conservation.

06:17Its remote location and difficult access

06:19making research and supervision a challenge in itself,

06:23where the crashing waves of the Indonesian Ocean limit exploration time.

06:29However, these new findings open up huge opportunities.

06:32for data-driven conservation.

06:35By understanding the ecological patterns and distribution of species,

06:38management of this area can be better structured,

06:42ensure that the wild ecosystem in Nusa Barung remains sustainable.

06:45Further research will continue to be conducted,

06:54including further monitoring of newly discovered species,

06:57as well as the possibility of other rare species

07:00which is still hidden in the corners of this island.

07:07Nusa Barung Island is a reminder that

07:10There are still many wild corners of Indonesia

07:12which we do not fully know.

07:14Every discovery here

07:16not only opens up new insights about biodiversity,

07:19but also emphasizes how important it is

07:22maintain this natural ecosystem.

07:25Amidst the roar of the waves of the Indonesian ocean,

07:27Nusa Barung remains standing as the last stronghold

07:30biodiversity,

07:32a natural heritage that we should protect

07:34for future generations.
