"Studi interaksi antara TiO2 dan ekstrak klorofil dari daun singkong (Manihot utilissima) telah dilakukan. TiO2 yang telah dibuat dengan metode Rapid Breakdown Anodization (RBA) dilapisi pada permukaan kaca substrat FTO dengan teknik doctor blade sebagai fotoanoda. Pengukuran dilakukan terhadap fotoanoda yang direndam maupun yang tidak direndam dengan ekstrak dyes. Interaksi antar komponen diukur menggunakan spektrofotometer UV-Vis/DRS dan FTIR. Spektrofotometer UV-Vis digunakan untuk mengukur adanya perubahan absorbansi sedangkan DRS digunakan untuk menentukan perubahan energi TiO2 yang telah direndam ekstrak dyes.
Spektrofotometer FTIR digunakan untuk menentukan karakteristik gugus fungsi. Kemudian juga diukur energi level HOMO LUMO dari ekstrak dyes dengan penentuan potensial oksidasi reduksi menggunakan metode voltametri siklik. Teknik Linear Sweep dan Multi Pulse Amperommetry digunakan untuk menentukan pengaruh penyinaran oleh sinar UV maupun sinar tampak pada fotoanoda sebelum dan sesudah perendaman dengan ekstrak dyes. Koefisien degradasi dan formasi serta koefisien difusi hole ekstrak dye diukur dengan menggunakan teknik spektroelektrokimia.
Komunikasi yang baik (good anchor) antara TiO2 dengan ekstrak dye klorofil alami dapat dilihat dari niali energi level LUMO dye (-4,26 eV) yang mendekati pita konduksi TiO2 (-4,3 eV), nilai koefisien degradasi dan formasi yang menunjukkan dye klorofil bersifat quasi reversible dan nilai koefisien difusi hole yang kecil menyebabkan terjadinya rekombinasi juga kecil sehingga bisa digunakan sebagai sensitizer.

ABSTRACT
With great economic potential of cassava in the world trade and the
increasing world demand for cassava as well as the limitations of Indonesia to
increase cassava production it needs to be investigated factors that can affect the
production, consumption and prices of cassava in Indonesia. Cassava production
is significantly influenced by the variable price of cassava, cassava harvested
area and price of urea fertilizer. Consumption of cassava in Indonesia is
significantly influenced by population of Indonesia. The price of cassava in
Indonesia is significantly influenced by cassava harvested area, consumption of
cassava and the length of tarred road. Based on projections, cassava production
would increase if cassava price, cassava land productivity and harvested area are
improved. Indonesian cassava consumption is projected to decline if there are
increasing in cassava price, per capita income and population of Indonesia
simultaneously. The price of cassava is projected to increase if the consumption of
cassava decreased accompanied by a decrease in the total area harvested
cassava., With great economic potential of cassava in the world trade and the

"Penelitian ini telah berupaya untuk meningkatkan tekstur keju yang dibuat dari susu sapi segar, dengan menggunakan pengganti enzim rennet sebagai koagulan. Susu mengandung dua protein utama yaitu kasein dan whey. Namun bagian yang penting untuk dijadikan keju adalah kasein, di mana kasein ini yang mengalami koagulasi untuk membentuk produk keju. Koagulan yang digunakan adalah kombinasi enzim papain dan transglutaminase.
Berdasarkan penelitian-penelitian sebelumnya, enzim papain bisa digunakan untuk mengkoagulasi kasein susu menjadi keju karena kemampuan proteolitiknya. Enzim transglutaminase digunakan untuk meningkatkan tekstur keju, dengan kemampuan ikatan silangnya. Proses pembuatan keju ini terdiri atas tiga variasi konsentrasi enzim papain yaitu 0,5; 1,5; dan 2;5 gram/100 ml susu untuk menentukan yield yang dihasilkan paling banyak, dan variasi kadar enzim transglutaminase sebesar 0,5; 1; 2 UE/gram protein susu atau setara dengan 0,027; 0,054; dan 0,11 gram enzim/100 ml susu.
Pada sampel keju terbaik yang dihasilkan dilakukan pengujian seberapa banyak yield, pH, uji FTIR, uji proksimat, mikrostruktur keju, uji potensial zeta, dan uji profil tekstur. Yield yang dihasilkan sebesar 23,33%, dengan pH 6,3, dan nilai puncak potensial zeta 0,97. Mikrostruktur keju yang diamati menggunakan Scanning Electron Microscope dengan perbesaran menunjukkan penambahan TGase menyebabkan koagulum lebih memadat. Nilai proksimat yang didapat menandakan penambahan TGase meningkatkan kadar lemak dan karbohidrat, dan menurunkan kadar air dan protein. Profil tekstur yang didapat menandakan keju dengan TGase lebih keras dan elastis karena adanya peningkatan kandungan lemak dan ikatan silang lebih lanjut pada matriks protein oleh TGase"

"Singkong dapat menjadi salah satu alternative dalam pengembangan bioethanol dan ekspor di Indonesia. Selain itu tanaman singkong hampir bisa kita jumpai dimana saja. Singkong yang sudah dikeringkan atau biasa di sebut gaplek memiliki nilai untuk di ekspor. Penelitian kali ini bertujuan untuk mengetahui karakterisasi dari singkong untuk dijadikan referensi dalam perancangan rotary dryer dan juga untuk mengetahui pengaruh dari temperatur, aliran udara dan tebal singkong terhadap laju pengeringan singkong.
Dalam kasus ini singkong akan dipotong dengan ukuran 0,3cm, 0,5cm, 0,7cm. Singkong yang diletakkan didalam ruang pengering akan dialirkan udara dengan 3 variasi ketinggian manometer yaitu 10mm, 18mm, 28mm. Udara yang dialirkan juga akan divariasikan temperaturnya yaitu 100℃, 80℃, 60℃. Hasil penelitian menunjukkan bahwa equilibrium moisture content (xe), konstanta pengeringan (k) dan α saling berhubungan. Critical moisture content (xc) sangat dipengaruhi oleh ketebalan potongan singkong dan laju aliran udara pengering.
