For three days in the first week of July, the singer and Doddy riding on a delman, a traditional horse-powered form of transportation, passed the vibrant Malioboro area in Yogyakarta and recorded songs about the species'€™ conservation.

The pair successfully recorded a song titled '€œBos Javanicus'€ written by Sarah while on the delman.

'€œThis is a creative way to express something efficiently and without costing too much money. This is the perfect time for musicians in Indonesia to consider using technology,'€ Doddy told The Jakarta Post.

'€œI used to spend millions of rupiahs on producing a record. But with recent technological advancements, not only can I do it for a lot less but the process can be done anywhere because it only requires a tablet and a special microphone.'€

With readily available programs such as Vocalive, AudioBus, Garage Band, Amplitube, Nave and Drum Jam, the noises that come from the surrounding cars can be muted down.

The duo also performed a similar gig at Yogyakarta Palace.

Doddy, who is popular for his one finger guitar technique, said the palace is considered a symbol of Javanese society. By associating the campaign to it, he hoped to reach wider awareness among local residents.

In the three-minute song '€œBos Javanicus'€, Doddy used a Rick Hanes Mr. D Squirrel Signature Series guitar, made in Surabaya.

After being named '€œGuitar of the year 2012'€ by UK-based guitar webzine Guitar Planet the Rick Hanes guitar is getting popular.

The former guitarist of rock band Boomerang was keen to participate in the cause after noticing the declining number of Javanese bulls.

Doddy said that there are no more than 8,000 bulls today. The International Union for Conservation of Nature (IUCN) categorized the Javanese bull as facing extinction in 1996.

Guitarist Doddy Hernanto and singer Sarah Fitria Andini record '€œBos Javanicus'€ on a delman.
'€œI was very interested in recording the sound of a Javanese bull in Baluran, but I only saw a deer and failed to even find a single bull,'€ he said.

'€œI'€™d like to encourage the younger generation to partake in saving these creatures,'€ said 20-year-old Sarah, a medicine student at Airlangga University in Surabaya.

Today, the number of Javanese bulls at Baluran Situbondo National Park is only 26. A staggering fact considering that in 2012, there were around 200 bulls there. There is also declining number of Javanese bulls at the Meru Betiri National Park in East Java.

Other than the diminishing habitat caused by land clearing, competition with predators like dholes and hunting threaten the species.

In an effort to minimize the decline in the number of Javanese bulls, the Forestry Ministry has implemented a semi-natural breeding program at the Baluran National Park with the support of Taman Safari Indonesia conservation area.

This program is similar to Taman Safari Indonesia Sumatran rhinoceros breeding effort at Way Kambas National Park. The purpose of this program, aside from breeding the species is to provide an area to study the behavior of the animal

There is also cross-breeding effort crossing Javanese bulls with Balinese cows at the Taman Safari Indonesia II in Prigen, East Java.

'€œMusic is a universal language through which people can send out messages. I am hopeful that the campaign will bring people together to support this cause,'€ the Wildlife Conservation Forum chairman and Taman Safari Indonesia II director, Michael Sumampauw, said.
