Apa Itu Just In Time dan Hubungannya dengan Lean?

Just In Time (JIT) adalah suatu sistem produksi yang dirancang untuk mendapatkan kualitas, menekan biaya, dan mencapai waktu penyerahan seefisien mungkin dengan menghapus seluruh jenis pemborosan yang terdapat dalam proses produksi sehingga perusahaan mampu menyerahkan produknya (baik barang maupun jasa) sesuai kehendak konsumen tepat waktu. Untuk mencapai sasaran dari sistem ini, perusahaan memproduksi hanya sebanyak jumlah yang dibutuhkan/diminta konsumen dan pada saat dibutuhkan sehingga dapat mengurangi biaya pemeliharaan maupun menekan kemungkinan kerusakan atau kerugian akibat menimbun barang.

Berdasarkan makna dari JIT tersebut, sehingga JIT juga dapat diaplikasikan dalam bidang jasa. Semua teknik JIT dalam hubungannya dengan para pemasok, tata letak, persediaan dan penjadwalan digunakan dalam sektor jasa.
Aplikasi prinsip JIT di bidang jasa tidak berbeda dengan apa yang dilakukan dalam bidang industri manufaktur. Beberapa contoh bagian dari industri jasa yang sudah sukses mengaplikasikan JIT adalah:
– Membuat penjadwalan yang tepat, sehingga tidak terjadi antrian atau konsumen yang terlalu      lama menunggu untuk mendapatkan pelayanan.
– Menggunakan tenaga kerja yang multifungsi sehingga kecepatan respon terhadap kebutuhan      layanan yang dibutuhkan konsumen juga meningkat.
– Perbaikan pada lokasi layanan yang berkaitan dengan kebersihan atau penataan tempat yang      efektif.

APA ITU JUST IN TIME ?
Just In Time (JIT) merupakan integrasi dari serangkaian aktivitas desain untuk mencapai produksi volume tinggi dengan menggunakan minimum persediaan untuk bahan baku. Konsep dasar dari sistem produksi JIT adalah memproduksi produk yang diperlukan, pada waktu dibutuhkan oleh pelanggan, dalam jumlah sesuai kebutuhan pelanggan, pada setiap tahap proses dalam sistem produksi dengan cara yang paling ekonomis atau paling efisien melalui eliminasi pemborosan (waste elimination) dan perbaikan terus – menerus (contionous process improvement).
Just in Time dan Lean Manufacturing adalah juga untuk meningkatkan laba dan posisi persaingan perusahaan yang dicapai melalui usaha pengendalian biaya, peningkatan kualitas, mengurangi pemborosan, serta menekan biaya operasional,dan akan sangat menghemat bahkan meniadakan biaya persediaan barang.
Sehingga didalam penjelasan diatas tidaklah menjadi etis atau keharusan pada perusahaan untuk menerapkan konsep Just In Time dan lean manufacturing pada setiap perusahaan,karena jika dilihat dari implikasinya dan penerapan penggunaanya pada lingkungan nyata, kedua konsep tersebut masih rancu atau masih belum bisa di implementasikan secara penuh oleh semua perusahaan.


APA ITU LEAN MANUFACTURING ?
Lean manufacturing atau lean production atau dikenal sebagai lean, merupakan metode optimal untuk memproduksi barang melalui peniadaan waste (pemborosan) dan penerapan flow (aliran), sebagai ganti batch dan antrian. Lena manufacturing adalah filosofi manajemen proses yang berasal dari Toyota Production System (TPS), yang terkenal karena menitikberatkan pada peniadaan seven waste dengan tujuan peningkatan kepuasan konsumen seccara keseluruhan.
Karakteristik dari lean meliputi struktur lantai produksi yang aktif melakukan pemecahan masalah dengan penerapan kaizen dan continuous improvement, serta pelaksanaan lean manufacturing melalui tingkat inventory yang rendah, manajemen kualitas yang mengutamakan tindakan preventif (pencegahan) dibandingkan tindakan corretive (perbaikan), penggunaan pekerja yang sedikit, ukuran lot yang kecil serta penerapan konsep Just in Time (JIT).

Lean manufacturing adalah strategi pencapaian yang signifikan, perbaikan yang berkesinambungan melalui eliminasi seluruh pemborosan waktu dan sumberdaya pada seluruh proses. Adapun yang dimaksud dengan pemborosan di sini meliputi 7 hal, yaitu:
  1. Transportasi
  2. Inventarisasi
  3. Pergerakan (proses)
  4. Waktu tunggu
  5. Produksi yang berlebihan
  6. Proses yang berlebihan
  7. Kerusakan produk

Kunci sukses Lean Manufacturing
  1. Mengurangi pengaturan biaya dan waktu
  2. Small lot production
  3. Keterlibatan karyawan dan pemberdayaan
  4. Fokus kualitas pada sumbernya
  5. Pull production atau just in time
  6. Perawatan equipment yang berkesinambungan
  7. Tenaga kerja yang multi-skill
  8. Keterlibatan supplier

Elemen utama dari lean production adalah:
  1. Produksi just in time (JIT), adalah suatu metode produksi yang membawa semua bahan baku dan suku cadang yang dibutuhkan dalam setiap produksi tepat pada saat dibutuhkan. Tujuan dari JIT adalah persediaan yang nol dengan kualitas 100%.
  2. Pengawasan kualitas yang ketat, dimana penghematan biaya maksimum dari JIT akan tercapai jika pembeli menerima barang yang sempurna dari pemasok. Dengan demikian pemasok harus menerapkan prosedur pengawasan yang sangat ketat sebelum barang tersebut diserahkan kepada pabrikan.
  3. Penyerahan beulang kali dan dapat diandalkan, dimana pengiriman ini sebaiknya dilakukan setaip hari untuk menghindari penumpukan persediaan. Bilamana terjadi keterlambatan akan pengiriman atau tidak memenuhi pemasokan maka pemasok dikenakan denda atau pemutusan kontrak kerja.
  4. Lokasi yang lebih dekat, dengan adanya lokasi yang berdekatan dengan pelanggan utama, maka penyerahan dapat diandalkan sehingga akan timbul komitmen yang besar dengan pelanggan utama.
  5. Telekomunikasi, dengan adanya perkembangan teknologi yang semakin pesat, maka pemasok dapat membangun sistem penyerahan yang lebih baik lagi.
  6. Jadwal produksi yang stabil, dimana pelanggan menyerahkan jadwal produksinya pada pemasok sehingga pemasok dapat menyerahkan barang sesuai dengan jadwal produksi pelanggan.
  7. Sumber tunggal dan keterlibatan awal pemasok, dimana dengan adanya JIT ini baik pemasok maupun pelanggan sudah terlibat dalam penyusunan kontrak kerja dan syarat-syarat lainnya.

Sehingga dengan kata lain tidak ada perbedaan yang signifikan antara JIT dengan lean manufacturing. Hal demikian dikarenakan just in time merupakan elemen utama dari lean manufacturing. Dan lean manufacturing melakukan penerapan konsep just in time.

A message for your other half

"You’re my best friend because I trust you with all of my deep secrets, and you trust me with all of yours. 
You know every embarrassing thing that’s happened to me, and I know every weird thing about you. I never hesitate to tell you something, because I know you will take it to your grave. If I need to call you at 3am, you will answer. If I don’t reach you, I can leave you a voicemail and I know you will call me the second you wake up. If I send you a string of demanding texts past midnight I know that you will be amused, and not annoyed.


We can make fun of each other and never take offence. You’ll always laugh at my inability to walk up stairs without panting and my disastrous attempts at styling my hair and my tendency to wear two different-coloured socks. But it’s cool, because I will always mock your love for One Direction.
You bring out my goofy side. We can talk to each other in weird accents for hours, have spontaneous dance sessions, and take the most ridiculous pictures of one another, just for the laughs.
You support my relationships. You may not think he’s right for me, you may find him odd, you may tell me I can do better — but as long as he treats me well and is a good person, you’re happy that I’m happy.
You’ve seen me at my worst, and you still love me. When bad days come, you know just how to cheer me up. You’ll play that one song, or suggest we watch that one movie, or take me to that one amazing cafĂ©. You’ll comfort me if I want, or give me space if I want to be alone. Somehow you always know what to do.
You believe that I deserve the best, and I believe that you deserve the best. We recognize each other’s hard work, and know that we are worthy of what we want, be it careers, relationships, etc. You are more than my best friend. You are my soul friend, and I appreciate you. I need you. I love you."

Aaak! Reaally love this quote of friendship! Every single word just makes me smile, I was like "yes that's freaking true how do u know thaaat?!"

People Leaves..

“But sometimes they wont fight for you. Sometimes they will just leave, without even hesitating.You need to be prepared for that. They will leave, and there’s not a thing you can do. Your perspective about them: destroyed. The person you love; gone. Not gone and ‘might be coming back’ gone. Really gone - because even if they might be coming back, everything you thought you knew and appreciate about them is gone - just because of the fact that you know they didn’t fight. Not that they need to put more effort into anything basically it’s just that I thought ending 5 years of a relationship would be a process and not just happen over night. it simply makes you rethink every moment. Which is worse than suddenly being alone now, because it feels like you have always been but you were just thinking you’re in love in someone who would fight.”

Scare Them


" Keep scaring them with your honesty, with your strength, with your kindness, with your love, with your understanding, with your words, with your eyes, with your presence and with your ability to read them. Keep reading them until you find someone who is just as fearless as you are and who won’t get scared off that easily, someone who is just as scary as you are that it starts to scare you.

Maybe you scare them because you don’t need them. Because they know you can survive without them, because they know that you won’t wait for them, because they know you will stand up for yourself and because they know that you will not allow yourself to be another number on their list.

Maybe you scare them because you value yourself, because you’re strong enough to walk away and because you’re smart enough to know your worth. Maybe they got so used to being put on a pedestal that they don’t know how to be anywhere else.
No matter what the reason may be, keep scaring them."

Listening to that song makes me forgot about the dark side of my love-life, and just having a new fantasy of love, um i mean.. look at the music video, it reminds me of a scene on 500 days of summer... Lovely! and quiet heartwrecking.


Music Video Here ---> Nathan Sykes - Over and Over Again


Lyrics

Over and Over Again

From the way you smile
To the way you look
You capture me
Unlike no other
From the first hello
Yeah, that's all it took
And suddenly
We had each other

And I won't leave you
Always be true
One plus one, two for life
Over and over again

So, don't ever think I need more
I've got the one to live for
No one else will do, and
I'm telling you
Just put your heart in my hands
Promise it won't get broken
We'll never forget this moment
It will stay brand new
'Cause I'll love you
Over and over again
Over and over again


From the heat of night
To the break of day
I'll keep you safe
And hold you forever.
And the sparks will fly
They will never fade
And every day gets better and better

And I won't leave you
Always be true
One plus one, two for life
Over and over again

So, don't ever think I need more
I've got the one to live for
No one else will do
I'm telling you
Just put your heart in my hands
I promise it won't get broken
We'll never forget this moment
It will stay brand new
'Cause I'll love you
Over and over again
Over and over again

Girl when I'm with you
I lose track of time
When I'm without you
You're stuck on my mind
I'll be all you need
Until the day that I die
I'll love you
Over and over again.

So, don't ever think I need more
I've got the one to live for
No one else will do,
I'm telling you
Just put your heart in my hands
I promise it won't get broken
We'll never forget this moment
It will stay brand new
'Cause I'll love you
Over and over again

Over and over again

Over and over again

Unspoken Fears

"What are you afraid of?"
A question that is often asked as a light question.
 People expect an answer like snakes or heights, something simple, something unimportant, actually.. 
But the truth is Im not afraid of spiders and I have absolutely no problem with taking the elevator.
Im afraid of time, how everything goes by way too soon, how i might run out of time before i even start living.
Im afraid of choosing a wrong person to build a life with, not knowing what love really is, not knowing there is more.
 Im afraid of making mistakes, being at the wrong place, at the wrong time, and completely messing up with my happiness.
 But those subject far too heavy for a small-talk and i'll just get a weird looks from the people who asked me. So I'll be polite, I'll say Im afraid of sharks, ducks, or big dogs.
But our real fears, are those unspoken. "

Promise The Stars

                                "Promise The Stars"
by: We The Kings




Let's take off in flight 
And race through the sky 
And like the hundreds of airplanes we're floating way up high 
We'll never look down 
We'll build our own town 
And like the thousands of clouds we will never touch the ground 

But would you risk some broken bones 
Just to call this place home 
This could be home 

Maybe I'm down low 
Maybe I'm up high 
Maybe I'm losing my own mind 
You know that there are no other two hearts closer than ours 
Maybe you'll follow 
Maybe you'll stay 
I'm praying you won't give yourself away 
You know that you are the only one I promise the stars 
You are 

With your hand in mine 
We'll soar through the night 
And like the dozens of spaceships we'll dance with sattelites 
We'll keep our eyes closed 
And we won't let go 
And with the millions of stars we'll will never be alone 

But would you risk some broken bones 
Just to call this place home 
This could be home 

Maybe I'm down low 
Maybe I'm up high 
Maybe I'm losing my own mind 
You know that there are no other two hearts closer than ours 
Maybe you'll follow 
Maybe you'll stay 
I'm praying you won't give yourself away 
You know that you are the only one I promise the stars 
You are 

I want you my only lover 
And I want you my only lover 

Maybe I'm down low 
Maybe I'm up high 
Maybe I'm losing my own mind 
You know that there are no other two hearts closer than ours 
Maybe you'll follow 
Maybe you'll stay 
I'm praying you won't give yourself away 
You know that you are the only one I promise the stars 

Maybe I'm down low 
Maybe I'm up high 
Maybe I'm losing my own mind 
You know that there are no other two hearts closer than ours 
Maybe you'll follow 
Maybe you'll stay 
I'm praying you won't give yourself away 
You know that you are the only one I promise the stars 

Maybe I'm down low 
Maybe I'm up high 
Maybe I'm losing my own mind 
You know that there are no other two hearts closer than ours 
Maybe you'll follow 
Maybe you'll stay 
I'm praying you won't give yourself away 
You know that you are the only one I promise the stars 
You are

Fear

She's afraid to get close to someone anymore..

She's afraid to believe in someone's words, 
Because once she believed them, 
They did the opposite things from what they said..

She doesn't like to be alone,
She wants to have someone in her life,
But life is too harsh to her..

Life force her to survive alone...                          When.. Now.. She's dying to have someone who can hold her and have a faith on her..
She's tired of waiting..                            

Waiting for miracle to come.. and surprise her.. 
She can only live in her deep imagination, drowning in her fantasy, and fading in her thoughts, alone..

...
She asked herself over and over again.. 

"When is it my turn to be happy?"
