Researchers from the Massachusetts Institute of Technology (MIT) campus, United States, successfully developed a watercress plant that is able to remove light by using nanoparticles contained in the leaves. This allows the tree to emit a light replacement lamp. The plant, allegedly can emit light for 4 hours.

One of the researchers, Michael Strano, hopes their findings can help us from the dependence of light coming from electricity. In addition, another goal of this research is to make plants that can function as table lamps, of course without electricity. [1]

Then how the plant can emit its light?

Researchers from the MIT campus said the light will radiate from the metabolism energy derived from the plant itself. Then in order for the plant to produce light, they use luciferase, a substance that gives light to fireflies.

Next, the researchers soaked the watercress plant in a solution containing luciferase, luciferin particles. Then they add a molecule called coenzyme A, this component is added in order to function to eliminate chemical reactions of both particles (luciferase and luciferin). [2]

The Luminous Tree in the Mountains of Indonesia

Meanwhile, in one of the mountains located in Binaiya, Maluku, Indonesia, there are trees that produce light at night. However, the light is not derived from the tree content but the light coming from the hundreds of fireflies that alight in the trees. [3]

If you come here at night, you will see the fiber and the flying fireflies that make the tree row there glowing like exposed to the light of the lamp.

Things like that will be very rarely seen in urban areas, because the species of firefly are rarely found in the city caused by pollution.

As for villages in the mountains Binaiya, Maluku, Indonesia, there are many fireflies is the village of Salumena. This is because the area is still clean and not polluted by pollution. Cold air is still enveloping this village.

watercress, Tanaman Bercahaya Temuan Peneliti Amerika Serikat

Para peneliti dari kampus Massachusetts Institute of Technology (MIT), Amerika Serikat, berhasil mengembangkan tanaman selada air yang mampu mengeluarkan cahaya dengan menggunakan nanopartikel yang terdapat di dalam daun. Hal ini memungkinan pohon untuk memancarkan cahaya penganti cahaya lampu. Tanaman tersebut, disinyalir dapat memancarkan cahaya selama 4 jam.

Salah satu peneliti, Michael Strano, berharap penemuan mereka dapat membantu kita dari ketergantungan cahaya yang berasal dari listrik. Selain itu, tujuan lain dari penelitian ini adalah untuk menjadikan tanaman yang dapat berfungs sebagai lampu meja, tentunya tanpa aliran listrik.[1]

Lalu bagaimana tanaman tersebut dapat memancarkan cahayanya?

Para peneliti dari kampus MIT tersebut menyebutkan, cahaya akan terpancar dari energi metabolisme yang berasal dari tanaman itu sendiri. Kemudian agar tanaman tersebut bisa menghasilkan cahaya, mereka menggunakan luciferase, sejenis zat yang memberikan cahaya pada kunang-kunang.

Selanjutnya, para peneliti merendam tanaman selada air tersebut dalam larutan yang mengandung partikel luciferase, luciferin. Kemudian mereka menambahkan molekul yang bernama coenzyme A, komponen ini ditambahkan agar dapat berfungsi menghilangkan reaksi kimia dari kedua partikel tersebut (luciferase dan luciferin).[2]

Pohon Bercahaya di Pegunungan Indonesia

Sementara itu, di salah satu pegunungan yang terletak di Binaiya, Maluku, Indonesia, terdapat pepohonan yang menghasilkan cahaya menjelang malam hari. Namun, cahaya tersebut bukan berasal dari kandungan pohon tersebut melainkan cahaya yang berasal dari ratusan kunang-kunang yang hinggap di pepohonan tersebut.[3]

Jika anda kesini menjelang malam hari, anda akan melihat seratudan kunang-kunang yang berterbangan yang membuat deretan pohon disitu bercahaya seperti terkena cahaya lampu.

Hal seperti itu akan sangat jarang anda saksikan di kawasan perkotaan, karena binatang jenis kunang-kunang jarang ditemukan di kota yang disebabkan oleh polusi.

Adapun desa di Pegunungan Binaiya, Maluku, Indonesia, yang banyak terdapat kunang-kunang adalah Desa Salumena. Hal ini dikarenakan kawasan ini masih bersih dan belum tercemar oleh polusi. Udara dinginpun masih menyelimuti desa ini.
