Sekolah Kardus

Semoga saja hasil uji coba tekanan terhadap kekuatan kardus KPU linier dengan luas bidang dimensinya.

Soal Kardus, beberapa hari ini ramai dibincangkan di banyak media. Terlebih di dunia online, dunianya antah berantah. Liar menjalar karena akarnya tidak menembus bumi, mencari sumber berita yang ke mana pun rimbanya. Kadang dibicarakan dengan sangat tidak terdidik atau sengaja dihembuskan angin ke mana akan berlabuhnya.

Saya berpikir tentang berita dari KPU (komisi pemilihan umum) untuk pesta demokrasi 2019. Berita tentang kotak suara yang terbuat dari bahan kardus, tapi sekuat baja. Bagaimana kekuatannya? Komisioner KPU, Ilham Saputra, mengaku takjub karena mampu menahan beban hingga 107 kilogram sesuai berat badan dirinya. Ilham juga menjamin keamanan kotak suara. Pengamanan bisa memakai gembok atau kabel khusus. Kekuatan kotak suara dari bahan karton tersebut juga dijamin Ketua KPUD Kendal, Jawa Tengah, Hevy Indah Oktarina. Bahan karton yang digunakan untuk kotak suara dan bilik suara itu cukup kedap air. https://beritagar.id/artikel/berita/soal-kotak-suara-kardus-kpu-yang-menghebohkan

Ada ide baru nih, saya tersenyum-senyum sendiri. Semoga saja hasil uji coba tekanan terhadap kekuatan kardus KPU linier dengan luas bidang dimensinya. Artinya semakin besar volume kardus, semakin tinggi kekuatan terhadap beban yang akan menderanya. Apalagi dipastikan, bahwa bahan kardus KPU kedap air.

Wah, aman tuh buat kelas baru di lahan baru. Kebetulan sekali, komunitas akan membangun kelas baru sebagai pengganti lahan Rawakopi yang habis masa sewanya. Lokasinya tidak terlalu jauh. Berkontur dekat genangan air berupa empang yang disulap menjadi danau sebagai pemanis view dan tempat belajar yang ‘asyik’.

Rencananya berdasar site plan dari tim pembangunan, ruang kelas berada dekat danau. Sedikit menjorok mengambil kesan bernuansa basah, tapi tidak terendam. Mungkin fondasinya yang mau tidak mau harus menopang kelas dari dasar danau. Kelas bisa ringan karena terbuat dari kardus, sementara kekuatannya sudah dijamin KPU karena memakai kardus KPU.

Nah, saya jadi berkeinginan kuat untuk segera mewujudkannya. Masa sih orang-orang sekelas anggota KPU asal bicara? Pasti mereka sudah mengujicobakan beberapa kali sehingga infonya disampaikan ke publik. Paling tidak sudah diuji dengan compression testing machine, yaitu alat penguji untuk mengetahui kekuatan bahan yang digunakan. Biasanya untuk kontruksi jalan dan jembatan. Menguji kekuatan bahan, seperti semen, beton, batako, batu bata, hingga berbagai komponen metal.

Saya berpikir sederhana, bisa juga digunakan untuk uji tekan terhadap kekuatan kardus. Toh, sama-sama untuk pengujian kekuatan. Bisa dicoba, kan. Biayanya pasti jauh dari anggaran pembangunan semi permanen apalagi permanen. Dapat ditekan dan pembangunan ruang-ruang kelas lebih cepat dari yang diperkirakan.
