BANDUNG, KOMPAS.com – Konversi minyak tanah ke  gas yang sempat menimbulkan kontroversi dikalangan warga masyarakat beberapa waktu lalu mengundang perhatian kalangan kelompok mahasiswa peneliti dari Universitas Padjadjaran (Unpad) Bandung yang kemudian berhasil menemukan alternatif pengganti minyak tanah.

Hasil penelitian kelompok mahasiswa Fakultas Farmasi Unpad menemukan bahan bakar yang mereka namakan “Jeli bioetanol” dari bahan utama  jerami menjadi pengganti minyak tanah ditampilkan pada Pameran Kreativitas Mahasiswa (PKM) di kampus Unpad Jalan Dipati Ukur Bandung, Kamis (11/6).

Salah seorang mahasiswa peneliti Sylvia, mengatakan jerami yang selama ini dianggap remeh tidak lebih dari sekedar limbah justru mengandung hemoselulosa dan jika dilakukan proses difermentasi dapat menghasilkan etanol. “Etanol merupakan zat mudah terbakar seperti terdapat pada  minyak tanah,” ucap Restu, anggota kelompok mahasiswa peneliti lainnya.

Bentuk jeli dipilih karena bersifat membungkus etanol dan pembungkusan itu bertujuan menjaga agar etanol tidak mudah menguap. Cara pembuatan jeli bioetanol tersebut cukup mudah, jerami dimasukkan ke dalam tempayan 15 liter yang kemudian diberi ragi.

Setelah itu, etanol menguap dan masuk ke dalam pipa kondensor untuk pengembunan. Kemudian yang muncul ialah cairan yang akhirnya diberi basis jel dan jadilah jeli  bioetanol yang siap digunakan sebagai bahan bakar. Penelitian kelompok mahasiswa Fakultas Farmasi Unpad  yang dilakukan awal maret 2009 itu dijadwalkan  rampung pertengahan Juni 2009.

Tim penelitian  mengaku belum akan memasarkan produknya, sebab mereka masih mencari formula tepat. Tapi jika selesai, hasil penelitian itu diharapkan dapat dimanfaatkan kalangan home industry dalam menggerakan usaha sebagai pengganti minyak tanah yang harganya terus melambung dan semakin sulit dicari.
