aku bukan siapa-siapa
aku hanya manusia biasa
aku tak punya banyak ilmu

aku bukan orang yang pandai bercerita
aku bukan orang yang pandai mencairkan suasana
aku bukan orang yang humoris

tapi aku suka mendengar orang bercerita
aku tertawa jika mendengar cerita lucu
aku berempati jika ada cerita sedih

lebih banyak mendengar
membuat aku banyak tau
membuat aku bisa memposisikan diriku
membuat aku bisa mengukur kemampuanku

Dalam bangku kuliah dulu ada salah satu mata kuliah yang namanya mekanika teknik. Kuliah ini banyak bercerita tentang beban, tegangan, gaya, defleksi dll. Rumus-rumusnya juga banyak yang turunan dan integral, tak jarang banyak mahasiswa yang tidak suka dengan mata kuliah ini dan menyebutnya dengan MKS (Mata Kuliah Setan) termasuk aku juga seh, hehehe…

Namun ternyata aku baru sadar apa yang diajarkan dalam bangku kuliah itu begitu penting saat kita berada di dunia kerja.

Pengalaman berikut semoga bisa menjadi motivasi untuk terus belajar.

Di tempat aku bekerja ada sebuah ponton akan dibuatkan gantry crane untuk mengangkat dan memindahkan tutup palkah yang ada di ponton tersebut. Material yang akan digunakan adalah beam. Nah permasalahannya adalah berapa ukuran beam yang mampu mengangkat beban tutup palkah sebesar P ton?

Untuk menyelesaikan permasalahan itu ternyata harus pakai rumus mektek agar bisa diketahui shear, momen dan defleksi yang terjadi. Berikut ini rumusan yang bisa di pakai.

Nah setelah tau rumusannya, kita tinggal mencari nilai-nilai yang diminta dalam rumusan tersebut. Seperti P, L, E dan I

Besarnya ukuran beam akan berpengaruh terhadap nila Inersia (I), semakin besar ukuran beam, maka nilai inersia nya juga akan semakin besar.

Sederhana kan?? Memang segala sesuatu akan mudah kalau kita tau ilmunya.

Cita-cita itu masih ada
Menjadikan Indonesia negara maritim

Tetapi apa itu negara maritim ?
masih belum jelas terdefinisikan

apakah negara yang memiliki laut luas melebihi daratan
atau negara yang memiliki banyak pulau
atau negara yang punya armada laut yang handal

entahlah, namun intinya mungkin
“negara yang mampu mengelola sumber daya bahari/kelautan”

Yang saya tau untuk mengetahui berat badan kita ideal apa tidak adalah dengan cara mengurangi tinggi badan kita dengan angka 110.

misalnya tinggi badan kita 170 cm
maka berat badan ideal kita adalah 170-110 = 60 kg

nah, ini ada situs yang mungkin bisa dijadikan perbandingan untuk mengukur berat badan ideal kita.
