INGIN TAHU CARA MENGHITUNG NIKMAT ALLAH SWT DENGAN MATEMATIKA?

Di kesempatan awal ramadhan 1439 H ini saya ingin berbagi tulisan tentang nikmat Allah yang kita terima begitu besar sekaligus mencoba menghitungnya dengan matematika. Hitungan ini hanya sebagai alat untuk mempertegas tentang ayat yang dimaksud sekaligus menambah kesadaran kita sebagai hambaNya yang harus senantiasa bersyukur.

Sebelumnya, saya mohon maaf pada guru-guru dan teman-teman saya yang mungkin lebih paham bahasa arab dan kaidahnya. Saya hanya meraba-raba sedikit pengetahuan yang saya miliki dan kiranya membuka maklum atas apa yang saya tulis jika terjadi kesalahan. Satu lagi, kalau ada masukan japri aja ya…xixixi

Ketika saya lulus MA (Madrasah Aliyah), acara lepas tasyakur yang biasa dilakukan oleh madrasah-madrasah pasca ujian nasional, latar acaranya bertuliskan “وَإِن تَعُدُّوا۟ نِعْمَةَ ٱللَّهِ لَا تُحْصُوهَآ ۗ إِنَّ ٱللَّهَ لَغَفُورٌۭ رَّحِيمٌۭ”, artinya kurang lebih “jika kamu menghitung/menyebut (mencacah) nikmat Allah maka tidak akan bisa dihitung jumlahnya, tak berhingga”(QS. AnNahl: 18).

Sedikit saya urai ayat itu dalam pandangan nahwu dan shorof. Bahwa kata تَعُدُّوا memiliki akar kata  عد. Saya ingat sekali, kata ini juga sewazan dengan “madda”, “yamuddu”. Kalau dibahas lebih jauh “madda” itu bina mudho’af. Dalam kamus Al-Munawwir, عد searti dengan hasiba dan ahso yaitu menghitung. Ahso sendiri dalam masyarakat Cina sebagai alat untuk menghitung. Kembali ke kata “madda”, تَعُدُّوا adalah bentuk fiil mudhori dengan mukhotobnya “kalian”. Fiil mudhori (present tense/ continous tense) boleh dilakukan berulang pada saat ini. Maksudnya, ayat itu menunjukan bahwa silakan kita terus melakukan hitungan (mencacah) kapanpun, saat inipun. Saya lebih suka menggunakan arti “mencacah” agar lebih mudah untuk menghitung. Dalam matematika, ada dua istilah populer bilangan, yaitu diskret dan kontinu. Diskret berarti dapat dihitung dengan mencacah, dengan tangan. Adapun kontinu adalah pekat, bilangannya tidak bisa dihitung dengan tangan, misal 1,2234 dan seterusnya. Kontinu itu mirip bilangan riil, atau bahasa sederhananya pecahan-pecahan (meski tidak begitu tepat).

Jadi seolah-olah ayat itu ingin mengajak kita semua untuk mencacah saja, tidak perlu dengan bilangan riil yang sulit, cukup dengan menghitung menggunakan jari. Yang dicacah adalah nikmat Allah. Kata “nikmat” juga unik, mengapa menggunakan kata dasar tunggal, bukan “niam” jamak dari kata nikmat. Hal ini juga membuka kesadaran kita bahwa Allah swt memberikan kesempatan kepada kita untuk menghitung (dengan jari) satu nikmat saja yang Allah berikan. Sanggupkah? padahal sudah dimudahkan dengan hitungan diskret.

Sekarang saya mencoba menjelaskan penghitungan satu nikmat saja dengan matematika. sebelum saya bahas lebih jauh, paling awal kita akan sepakat dulu dengan istilah “nikmat”. Nikmat itu apa? Pembahasan kali ini, saya tidak mengartikan nikmat sebagai kata sifat, tetapi digunakan sebagai kata benda, yaitu pemberian Allah (KBBI online).

Nikmat Allah dapat berupa fisik dan nonfisik. Agar lebih mudah, penghitungan nikmat ini juga dibatasi pada bentuk fisik. Nikmat fisik ini lebih mudah dihitung daripada nonfisik. Sekarang, kita breakdown lagi nikmat fisik yang lebih mudah lagi yaitu nikmat yang ada dalam diri kita. Mata, telinga, hidung, mulut, tangan, kaki, dan banyak lagi. Dari mata, kita bisa buka lagi nikmat yang lain yaitu bagian-bagian mata misal pupil, retina, kornea, saraf, alis, bulu mata dan sebagainya. Di dalam retina, misalnya, terdapat syaraf-syaraf dan sel-sel lagi yang lebih kecil. Andaikan sel yang terkecil dari yang terkecil itu diberi simbol   (baca: epsilon). Epsilon biasanya melambangkan bilangan terkecil positif yang mendekati nol. Epsilon bisa kita ilustrasikan sebagai sel yang terkecil dari yang terkecil tadi. Jika manusia hidup dari pertama kali ditiupkan ruh sampai ajal menjemput berarti kita bisa membuat interval waktu (t) sebagai 0 < t < .

Hubungan antara waktu (t) dan kehidupan manusia dapat dilukiskan secara grafis sebagi sebuah fungsi.

Andaikan luas di bawah kurva adalah luas nikmat sel terkecil kehidupan setiap orang. Ingat luas sel terkecil (Epsilon). Kurva nampak bergelombang tidak linier, karena memang kehidupan tidak selalu monoton, tidak selalu bahagia atau sedih, tidak selalu konstan. Sekarang kita akan menghitung luas daerah sel terkecil tersebut di bawah kurva. Menggunakan Riemann Sum, kita bisa menghitung luas daerah di bawah kurva meski batas atasnya tidak beraturan. Riemann sum merupakan metode menghitung luas kurva dengan cara membuat partisi-partisi yang membentuk persegi panjang atau trapesium. Semakin banyak partisi, tingkat kesalahannya semakin kecil.

Menghitung luas daerah yang dibatasi oleh a < t < b, kita hanya menghitung dengan batas a dan b yangmerupakan sebagian dari waktu kehidupan seseorang, menggunakan rumus integral sebagai berikut.

Jika dalam satu sel terkecil saja mendapatkan satu rumus integral, maka integral rangkap berapa untuk menghitung satu syaraf dalam satu komponen retina. Boleh jadi untuk satu sel saja didapat rumus intergral.

Padahal dalam syaraf terdapat sel-sel, lalu berapa rangkap untuk satu syaraf. Lebih jauh lagi intergral rangkap berapa untuk satu nikmat retina? TIDAK BISA DIHITUNG, itu baru retina, belum bagian mata yang lain. Oleh karena itu, benarlah ayat Alquran sebagaimana dijelaskan di depan.

Ingin Tahu Asal Simbol “X” dalam Matematika?

Anda yang pernah sekolah di tingkat dasar sampai perguruan tinggi, pasti tidak asing dengan simbol “x”. Simbol ini sering dikaitkan dengan pelajaran matematika, pelajaran yang banyak mendapat tempat tidak nyaman di hati siswa.
Simbol “x” adalah variabel/peubah yang bermakna kondisional bergantung pada pembuat arti. Ini yang dalam matematika disebut artifisial. Yang lebih cocok untuk menggambarkan arti “x” adalah “sesuatu”. Mirip kalau dulu saya belajar bahasa arab tentang asmaul khomsah, yang salah satunya “hanuuka”, yang berarti “anu”/ sesuatu.

Sebenarnya, simbol “x” itu apa dan darimana?
Kali ini saya akan memaparkan sedikit tentang simbol “x”.
Tidak dipungkiri, matematikawan muslim seperti Alkhowarizmi, Al Jaali, Ibnu Rusyd, Ibnu Sina dan sebagainya adalah pelopor berdirinya dasar2 matematika. Alkhowarizmi, misalnya, mencetuskan satu konsep variabel yang tertulis dalam kitabnya, Aljabbar Wal munqobalah, sebagai akar keilmuan matematika lanjutan.
Termasuk di dalamnya variabel x yang sebenarnya berupa huruf “ش”, yang kepanjangannya “شىء”, sesuatu. Penulisan “ش” oleh orang-orang barat kemudian berubah menjadi “x” sampai sekarang. Jadi simbol/variabel x  berasal dari bahasa arab.

Jika ditarik lebih dalam, sesuatu yang dalam hal ini “شىء”, merupakan sikap kerendahan diri bahwa kita memiliki sesuatu yang tidak bisa digambarkan tapi hanya disimbolkan. Sesuatu itu berpengaruh pada rumus-rumus matematika lain seperti pengaruh sesuatu itu pada kehidupan ini.

Melipat Kertas 42 Kali, Sampai Ke Bulan? Berikut Secara Matematis

Percayakah anda, bahwa dengan melipat kertas seukuran A4 sebanyak 42 kali, lalu hasil lipatannya ditumpuk, maka bentangan tumpukan itu bisa mencapai bulan!

Bagaimana mungkin? Mari kita lihat perhitungan sederhananya. Rata-rata ketebalan kertas adalah 0.1 mm. Kalau kita lipat selembar kertas sekali akan diperoleh 2 tumpukan. Kalau ini dilipat lagi, maka pada lipatan kedua akan menghasilkan 4 tumpukan (22). Demikian seterusnya, sehingga pada lipatan ke-42 akan diperoleh 242 tumpukan. Berarti ketebalannya adalah 242 × 0.1 × 10-6 km ≅ 439 805 km. Ini melebihi jarak rata-rata bumi – bulan sebesar 384 400 km.  Jadi secara matematis masuk akal, bukan?

Tetapi pada prakteknya mungkinkah hal ini bisa dilakukan?  Cobalah lipat secara berulang selembar kertas berukuran sedang. Maksimum kita dapat melakukannya hanya sampai 6-7 lipatan!  Lagipula 242 tumpukan itu sama dengan 4 398 046 511 104 (hampir 4.4 triliun) tumpukan.  Bisa dibayangkan andaikan bisa betapa kecilnya ukuran tumpukan itu. Mungkin wujud fisik kertas sudah tidak bisa dilihat lagi.

Inilah sebuah contoh yang sangat sederhana bahwa apa yang tidak mungkin secara praktis, bisa jadi masih mungkin secara matematis.  Namun demikian, tidak sedikit fenomena-fenomena alam seperti prediksi gempa bumi, tsunami yang baru bisa didekati secara matematis.  Konsep-konsep matematika umumnya bersifat abstrak.  Dari konsep-konsep abstrak inilah kemudian banyak lahir model-model matematik yang digunakan untuk membantu mengungkap fenomena-fenomena alam atau permasalahan-permasalahan dalam kehidupan sehari-hari.  Sang ilmuwan besar – Galileo menulis, “The great book of nature can be read only by those who know the language in which it was written. And that language is mathematics…”  Karena itu, janganlah membenci matematika.  Bila alat-alat canggih komunikasi, transportasi, dll. “dibedah”, pasti di sana ditemukan matematika.  Ia adalah alat bantu untuk bisa sukses dalam era persaingan global yang makin ketat dewasa ini…
