Yagitudeh: Pake Lagi Minyak Goreng Bekas
Ini yang jadi pertanyaan banyak orang, mulai dari emakku yang doyan masak, sampai dengan seorang ibu di acara Green Fest kemarin: Menyak goreng abis dipake, kalo udah nggak layak pake lagi, diapain yah?
Kalo jumlahnya sedikit sih masih mending bisa dimasukin ke kotak kompos. Tapi kalo udah dalam jumlah yang banyak? Ga mungkin juga lah ya. Dibuang gitu aja?
Kebetulan, waktu ibu-ibu Green Fest itu tanya, saya baru aja mencari-cari tahu dari Om Gugel, jadinya saya bisa cuap-cuap ngecap-ngecap sedikit, walau belum ada satu pun yang saya dipraktekin. Tapi, saya tertarik juga untuk coba bikin sabun (ya betul! sabun… seperti sabun yang dipake untuk cuci tangan itu).
Mungkin minggu depan saya mau coba bikin sabun.
Jadi… beberapa hal di antara banyak hal yang bisa dilakukan dengan menggunakan minyak goreng bekas adalah:
Pengganti bahan bakar kendaraan
Terutama untuk kendaraan-kendaraan bermesin diesel. Pertama kali saya tau ini dari salah satu stasiun televisi musik sekitar tahun lalu. Ceritanya ada salah seorang artis bule yang menggunakan minyak jelantah untuk bis tur keliling negerinya. Jadi, dia tidak pusing kalau misalnya harus tur ke daerah-daerah yang rada jauh. Tinggal berhenti di suatu restoran, minta jelantahnya (kadang kalo bayar ya uwis… kadang dia didaulat nyanyi sebagai ganti sejerigen dua jerigen jelantah).
Di Indonesia, penggunaan jelantah sebagai bahan bakar alternatif juga sudah mulai marak lho. Di Bogor misalnya, pemerintah kota Bogor sudah mulai menggunakan minyak jelantah, yang dicampur solar (entah diseling-seling sama solar, atau dicampur beneran sama solar ya?) ini untuk kendaraan operasional pemerintah dan juga angkot Transpakuan.
Kalo di Bali ada Pak Olivier yang menggunakan minyak goreng bekas pakai sebagai bahan bakar truk. Kalau ada yang mau menyumbang minyak goreng atau bertanya-tanya, silakan hubungi beliau.
Dijadikan sabun
Jadi inget yang di filemnya Brad Pitt itu ya, yang Fight Club. Hehehe… bikin sabun secara rumahan. Intinya sih, karena menggunakan bahan soda api (caustic soda alias sodium hidroksida, NaOH), sabun ini sebaiknya nggak dipake untuk cuci muka dan jangan sampe kena mata. Mungkin paling banter bisa untuk bersih-bersih rumah, bisa untuk cuci-cuci baju, atau paling jauh ya untuk cuci tangan.
Bahan soda api (caustic soda) ini emang sering dipake untuk bikin deterjen kok.
Untuk jelasnya, gimana cara bikinnya, silakan liat di sini. Jurusnya cuma: aduk, aduk, aduk. Dan jangan sentuh soda api dengan tangan yang tak terlindungi. Pakelah perlindungan.
Oh iya, walau semua tipe minyak goreng sebenernya bisa dipake untuk bikin sabun ini, kayaknya (menurut sumber-sumber yang aku baca, paling bagus itu minyak kelapa).
Digunakan untuk mencegah rerumputan/tumbuhan liar
Buat yang suka berkebun, gunakan minyak goreng bekas pakai sebagai salah satu bahan sungkupan (untuk mulching). Jadi ceritanya, kertas bekas direndam dengan minyak goreng ini, lalu diletakkan di bagian bawah sungkupan itu.
Katanya nih, kalau di daerah yang adem-adem dingin (negara yang ada musim seminya), sungkupan berbahan minyak goreng malah bikin rerumputan liar ini cepet tumbuh. Tapi… karena kita tinggal di daerah tropis alias panas, menggunakan sungkupan dengan campuran minyak bekas ini malah mencegah, memperlambat, bahkan membunuh rerumputan liar. Oke banget, kan?
Info lebih lanjut sila buka halaman ini, lihat di bawah sub-judul "Paper Mulches".
Catatan kecil lainnya
Oh iya, kalau emang misalnya minyaknya rada berbau oye (misalnya abis ngegoreng yang enak-enak) dan takut kalau terlalu bau yah… bisa "dibersihin dulu". Menurut salah satu halaman web di bawah itu tuh *tunjuk-tunjuk* caranya:
- masukin ke dalam toples atau wadah yang cukup, masukkan minyak bekas dan air (perbandingan 1:1)
- abis gitu, sinar-sinarin di bawah matahari, sekitar 2 harian. Kocok seingetnya.
- nanti, tujuannya itu supaya hal-hal jelek yang terperangkap dalam minyak itu pindah masuk ke dalam air.
- kalau minyak sudah keliatan agak oke, dan air berubah menjadi agak buram, pisahkan minyak dari air.
- silakan dipake buat hal-hal lainnya yang dianggap asik.
Nah, kalau ada yang punya info lainnya, monggo lho kalau mau dibagi. Hihihi, supaya minyak gorengnya nggak "habis manis sepah dibuang"… Apalagi kalau masih bisa dipake.

emang artikel si hence ini menarik, maju terus bu!
