Weekend ini akhirnya kesampain juga nonton Iron Man sama keluarga. Terutama si kecil yang sudah nggak sabar, trailer Iron Man di youtube -dibaca ama junior yo-u-tu-be- pun direplay berulang-ulang. Seperti nggak ada bosennya untuk melihat aksi Iron Man walaupun sekilas sahaja.

Boleh komentar tentang video ini disini kok.

[...] Controversial Turkish Islamic author Adnan Oktar was sentenced to three years in prison on Friday for creating an illegal organization for personal gain, state-run Anatolian news agency said. [...]

–Reuters

Di atas adalah sedikit cuplikan dari Reuters mengenai berita divonisnya hukuman tiga tahun penjara kepada Adnan Oktar alias Harun Yahya. Menilik pada reputasi buruknya–tentu saja di negara yang mengenal beliau dengan baik, ini bukan berita yang mengejutkan, setidaknya bagi saya juga.

Beruntung sekali bagi bung Roy Suryo yang juga merupakan pakar™ seperti Harun Yahya. Beliau yang satu ini bisa menjaga diri sehingga tidak melakukan hal-hal yang ilegal seperti yang dilakukan tokoh yang memiliki fenomena yang sama dengan dirinya tersebut. Fenomena kepakaran™ tokoh populer dengan para fans fanatik yang seringkali lupa melakukan cross-check untuk membuktikan kredibilitas sang pakar™.

Kelihatannya kebenaran sudah mulai terkuak dengan kasus ini.

Bahan :

- LED. Yang banyak. Gw pake 6 LED putih.
- Push on Switch
- Batere 9 volt
- Kabel
- Karton
- Sarung Tangan
- Waktu luang

Cara :
Gunting karton supaya ngebentuk kotak, trus bolong-bolongin bagian tengahnya supaya bisa masuk kaki LED.
Hubungkan 3 LED secara seri, jadi ada 2 “seri”. Kedua seri ini lalu diparalel. Skematiknya kayak gini :

Hubungkan kabel dengan switch, atur supaya switch itu bisa diteken tanpa harus melibatkan tangan lain. Gw susun supaya switch diteken pas gw ngepal.

Atur-atur dikit bentuk kotaknya biar indah, trus pasang di sarung tangan.

Like this :

Trus gaya dikit lalu ambil foto :

Dengan sedikit usaha dan redesign, kita bisa bikin kayak gini :

Yeah. Totally. Uh…generator power 3 juta watt segede gelas kopi di dada dan otak lulusan summa cum laude MIT di umur 17 tahun juga mungkin membantu.

P.S. : Gak yakin ada orang aneh yang iseng mau bikin juga, tapi yang mau step-by-step lebih detil bilang o.o

The angel on the stairs
will tell you I was there
Under the front porch light
on a mystery night

I’ve been sitting watching life pass from the sidelines
Been waiting for a dream to seep in through my blinds
I wondered what might happen if I left this all behind
Would the wind be at my back?
Could I get you off my mind?
This time

The neon lights in bars
and headlights from the cars
Have started a symphony
surrounding me

The things I left behind
have melted in my mind
And now there’s a purity
inside of me

I’ve been sitting watching life pass from the sidelines
Been waiting for a dream to seep in through my blinds
I wondered what might happen if I left this all behind
Would the wind be at my back?
Could I get you off my mind?
This time

I’ve been sitting watching life pass from the sidelines
Been waiting for a dream to seep in through my blinds
I wondered what might happen if I left this all behind
Would the wind be at my back?
Could I get you off my mind?
This time

*could I get you off my mind ? *

  Kecoa merupakan binatang yang bisa menyebarkan penyakit. Nah cara sederhana dan ampuh untuk mengusirnya adalah dengan meletakkan kaleng berisi minyak tanah disekitar tempat keluar masuk kecoa. Karena serangga ini sangat anti terhadap minyak tanah maka kecoapun akan jauh-jauh menyingkir.

  Hanya saja sekarang minyak tanah sangat sulit didapat dan kalaupun inging mendapatkannya harus antri menganak sungai. Jadi mungkin tips ini jadi tidak berguna karena minyak tanahnya tidak ada.
  Atau di luar sana ada ide yang lebih cemerlang?

Hollow fiber membrane merupakan salah satu jenis membran yang banyak digunakan dalam industri makanan.

Membran? Tentunya teknologi yang satu ini bukan merupakan hal yang asing di telinga teman-teman mahasiswa Teknik Kimia. Aplikasi dari teknologi membran ini tersebar luas mulai dari pengolahan air (yang paling umum), teknologi pengolahan gas (seperti yang telah dibahas oleh teman saya dalam artikel sebelumnya), bahkan pengolahan limbah (contohnya yang sedang ramai dibicarakan adalah membrane bioreaktor dengan banyak variannya).

Secara sederhana membran adalah lapisan yang dapat secara selektif memisahkan satu zat dari zat lainnya dengan driving force pada umumnya adalah beda tekanan, beda temperatur, beda konsentrasi, beda energi potensial listrik atau kombinasi diantara keempatnya. Bila teman-teman tertarik dengan teknologi membran dan ingin mendapatkan pemahaman lebih dalam baik dari konsep dasar teori dan beberapa penerapannya, teman-teman dapat membaca buku “Basic Principle on Membrane Technology” karangan Mulder yang diterbitkan oleh Kluwer Press.

Membran dalam Pemrosesan Pangan

Konfigurasi membran yang telah dipakai dalam teknologi pangan sangat bervariasi mulai dari hollow fiber hingga spiral wound. Aplikasinya pun sangat beragam mulai dari klarifikasi bahan pangan, konsentrasi/pemekatan bahan pangan, pengolahan air limbah industri pangan untuk dipakai kembali (reused water), dan masih banyak macamnya. Secara umum, keunggulan teknologi membran dalam pemrosesan pangan dapat digolongkan menjadi dua yaitu:

1. Peningkatan proses produksi, yang dicapai karena :
   • Tingginya kualitas retentate atau permeat secara konsisten
   • Mengurangi biaya operasi
   • Tidak terlalu ketat dalam maintenance
   • Rendahnya hilang tekan
   • Pada umumnya tidak melibatkan zat kimia dan/atau temperatur yang tinggi (yang dapat menurunkan kualitas makanan)
   • Umur operasi membran yang tahan lama
   • Tidak memakan tempat dan mengurangi biaya lahan
2. Dapat memberikan recovery bahan pangan yang masih berharga yang biasanya terbuang bersama limbah

Nah, apa saja sih teknologi membran yang sudah diterapkan di industri pemrosesan pangan? Marilah kita tinjau satu per satu:

Reverse osmosis. Teknologi reverse osmosis dapat digunakan untuk memproduksi air bersih dengan konsentrasi mineral yang konsisten untuk menjamin kualitas produk pangan.

Teknologi Membran. Implementasi teknologi membran pada industri pangan akan memberikan banyak keuntungan baik secara teknis maupun ekonomis.

1. Mikrofiltrasi (MF)

   Ini adalah salah satu teknologi pangan yang sudah dipakai secara luas di industri pemrosesan pangan umumnya dipakai dalam proses klarifikasi bahan pangan, bisa juga untuk sentrifugasi, alat sterilisasi, pemisahan suspended solid dan penyingkiran High Molecular Protein (HMW). Contoh aplikasi dari Teknologi MF ini adalah pada industri susu dan produk susu, dimana membran digunakan mengklarifikasi dadih keju, menghilangkan lemak (de-fat) dan mengurangi kandungan mikroba di dalam susu.

2. Ultrafiltrasi (UF)

   Teknologi UF dipakai dalam proses fraksionasi, konsentrasi/pemekatan, dan purifikasi. Contohnya dalam industri susu. UF dipakai untuk memfraksionasi susu untuk memproduksi susu dimana di dalam permeatnya terkandung protein, lemak, dan garam tak larut sedangkan di dalam retentate /konsentratnya terkandung laktosa dan garam terlarut. Contoh lainnya, masih dari industri susu, adalah konsentarasi dari susu skim sehingga mempunyai kandungan protein dan kalsium yang tinggi. Aplikasi lain yang juga populer (selain dalam industri susu) adalah dalam pengolahan jus buah. Dalam hal ini, teknologi UF digunakan untuk mengklarifikasi jus buah dari kontaminan-kontaminan seperti ragi, kapang, dan bakteri untuk meningkatkan kualitas dari jus buah tersebut.

3. Nanofiltrasi (NF)

   NF umumnya dipakai jika kita ingin memisahkan campuran komponen (desirable component dari undesirable component) yang pada umumnya akan sulit dipisahkan karena kecilnya ukuran partikel. Contohnya adalah pada proses pemekatan sirup jagung (corn syrup). Penerapan lain teknologi NF adalah untuk proses demineralisasi parsial dan pemekatan secara simultan, misalnya pada proses demineralisasi dari dadih susu.

4. Reverse Osmosis (RO)
   Pada umumnya teknologi RO digunakan dalam proses pemurnian air (tawar dan laut) serta desalinasi air laut, hal ini dikarenakan membran jenis RO dapat merejeksi partikel garam hingga 99% konsentrasi. Akan tetapi bagaimana penerapannya di dalam teknologi pangan? Dalam pemrosesan pangan, teknologi RO digunakan untuk proses pemekatan, pemurnian, dan recovery dari valuable product dalam bahan pangan. Keunggulan teknologi RO dibandingkan teknologi lainnya adalah:
   • Diperoleh produk yang berkualitas tinggi tanpa perlu melalui proses pemanasan (karena dapat merusak bahan pangan)
   • Mengurangi volume limbah, sehingga biaya pengolahan limbah berkurang secara signifikan
   • Biaya modal yang cenderung lebih murah dibandingkan proses untuk aplikasi sejenis
5. Electrodialysis (ED)
   Teknologi ED digunakan dalam proses demineralisasi susu dan dadih susu, pengurangan keasaman (de-acidfy) dalam jus buah, penghilangan komponen terlarut (de-ash) dari larutan gula (dextrose). ‘Saingan’ dari teknologi ED adalah teknologi ion-exchange (IEX). Akan tetapi, pada proses yang bersifat kontinyu, ED cenderung dipakai karena lebih ekonomis. Perkembangan terbaru dari teknologi ED adalah kombinasi/hybrid dari ED dengan IEX yang dikenal dengan istilah electrodeionization.

Selain teknologi-teknologi yang telah dijabarkan diatas masih banyak lagi teknologi membran di dalam industri pemrosesan pangan. Salah satu yang sedang populer sekarang ini adalah teknologi pervaporasi yang banyak dipakai dalam pemisahan campuran alkohol (etanol) dengan air dan campuran azeotrop lainnya.
