Solusinya ... di .htaccess file di webroot bikin jadi gini

<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteBase /
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]

bukan gini

tugas kita berbuat baik bukan membuat orang bahagia

uang tidak bs membeli kebahagiaan.. iya.. mungkin karena uangnya sedikit 😂

action dengan cepat dan harus terarah boleh melambat atau istirahat tp jangan menyerah

menjadi akrab
bukan berarti
berkurangnya adab

pilih mana... 
lelah karena kerja
atau 
lelah mencari kerja 
?? 

maka bersyukurlah

pilih
 mana..
lelah karena kerja
atau 
lelah mencari kerja 
?? 

maka bersyukurlah

merasa berdosa lebih baik dari pada merasa telah berbuat baik

the best you ever made is you - bagusin dirimu untuk kamu tuliskan 
      di cv itu. buat cv mu saat ini dan 3 tahun mendatang.

narasi - cerita singkat ttg diri, karakter,  asal kota, pendidikan 
terakhir, ipk, thn lahir, umur  dll. singkat padat jelas

fokus - tonjolkan pada yg baik2
pengalaman kerja dan portfolio yg tidak relevan dengan posisi yg 
di tuju maka di hapus aja, tulis yg relevan saja

cv ats - bikin cv ats tapi desain bagus
cv ats - posisi bisnis, submit platform, screening applicant 
tracking system
cv kreatif - posisi desainer dll, submit ke email/personal, 
dibaca oleh recruiter

max 2 halaman

kontak
======
no wa & linkedin wajib
sosmed lain dihapus aja - hati2 ber sosmed
jgn pake email alay
alamat lengkap g usah, kota domisili aja

gunakan istilah yg keren misal tukang bantu fotokopi dosen jadi 
administrative assistant

pisahkan skill, achievement dan portfolio
skill d ukur dengan achievement
skill di buktikan dengan portfolio

pengalaman kerja
===============
- jgn terkesan kutu loncat, hati2 dengan banyak penglaman kerja tapi 
  cuma sebentar.
- tulis pencapaian ketika kerja. solve problem apa, bisa menaikan apa 
  dari berapa jadi berapa
- pengalaman yg tidak relate dengan posisi tujuan di hapus aja

kalo ada emak2 naik motor dijalan
posisi lampu sen nyala, jgn terlalu percaya
tetap waspada demi keselamatan Anda.

yang mati hari ini sama seperti kita...
mungkin tidak menyangka besoknya akan mati

belajarlah minta maaf dan memaafkan
karena manusia tidak luput dari kesalahan-kesalahan

kita itu di dunia membangun cerita
cerita nyata yg suatu saat akan dibuka 
dibaca dan tidak hanya d baca 
tapi d nilai dan diadili oleh sang Pencipta
maka goreskanlah cerita yg baik 
di setiap momennya

jatuh di 2 hal ini akan membuat anda berdebar-debar tidak karuan

1.jatuh cinta
2.jatuh tempo

yg pertama bikin bahagia
yg kedua bikin bahaya

yg pertama bikin jadi senang
yg kedua bikin pengen ngilang

rasakan bedanya ..🤣😂🤣😂
