Cassava leaves (Manihot esculenta C.) have a total chlorophyll of 27.4667 mg/g, the second highest after papaya leaves. Plants containing chlorophyll can be used as raw materials to make green powder natural dyes. The method used in the manufacture of powdered natural dyes is foam mat drying. the process of making natural dye powder with foam mat drying method added with maltodextrin and MgCO3. The purpose of this study was to determine the optimum formula for natural dyes of cassava leaf powder with variations of maltodextrin and MgCO3 and to determine the physical and chemical supporting characteristics of the optimum formula for natural dyes of cassava leaf powder. The results showed that the optimum formula of cassava leaf natural coloring powder is F5. Variations in the comparison of maltodextrin and MgCO3 concentrations in the optimum formula obtained the water content value of 4.44%; dissolving time 41 seconds; pH 8.2; value of L* 53.0; value a* -21,4; b* 18.9; the degradation of the stability of the heating time of the oven and the stability of the heating time of the hot plate are 11.59% and 11.92%; hue value 138.55o ; chroma value 28.55; and total chlorophyll content of 14,231 mg/g. In addition, the application to textiles with a color resistance test found that the decrease in the mass of the fabric did not change too much.

Tumbuhan yang mengandung klorofil dapat digunakan sebagai bahan baku pembuatan pewarna alami serbuk hijau. Metode yang digunakan dalam pembuatan serbuk pewarna alami adalah foam mat drying. Proses pembuatan serbuk pewarna alami dengan metode foam mat drying ditambah maltodekstrin dan MgCO3. Tujuan dari penelitian ini adalah untuk menentukan formula pewarna serbuk daun singkong yang optimum dengan variasi maltodekstrin dan MgCO3 serta menentukan sifat fisik dan kimia pendukung dari ekstrak daun singkong. Formula optimum pewarna alami serbuk daun singkong. Hasil penelitian menunjukkan bahwa formula serbuk pewarna alami daun singkong yang optimal adalah formula F5. Variasi perbandingan konsentrasi maltodekstrin dan MgCO3 pada formula optimum diperoleh nilai kadar air sebesar 4,44%; waktu larut 41 detik; pH 8,2; nilai L* 53,0; nilai a* -21,4; b* 18.9; penurunan stabilitas waktu pemanasan oven dan stabilitas waktu pemanasan hot plate masing-masing sebesar 11,59% dan 11,92%; nilai hue 138,55o ; nilai chroma 28,55; dan kandungan klorofil total 14.231 mg/g. Selain itu, aplikasi pada tekstil dengan uji ketahanan warna didapatkan bahwa penurunan massa kain tidak terlalu banyak berubah.

Cork eggs from mackerel are a snack in the form of long thin strands such as cendol made from tapioca flour, mackerel meat, egg yolks, cheese, salt and water which are fried and have a savory taste and crunchy texture, the addition of natural coloring leaf extract cassava cork egg product from mackerel is intended to increase the nutritional value of cork egg snack from mackerel. The addition of natural dyes from cassava leaf extract, cork egg products from mackerel, is intended not only to beautify the appearance of the product, but also to increase the nutritional value of the cork egg snack from mackerel. This research was conducted by experimental method with complete randomized design one factor, namely the treatment of cassava leaf extract concentration as an additive where the research stage consists of three stages with descriptive data analysis techniques. The results showed that Cork eggs which have the highest antioxidant activity is in treatment A3 with a value of 103.04 µ g/ml.

Synthesis and characterization of TiO2 films sensitized with chlorophyll and metal-chlorophyll complex (M=Zn2+, Co2+) were carried out. Chlorophyll isolated from cassava leaves shows absorption peaks on the UV-Vis spectra in the Soret band area (415 nm) and Q band area (665 nm). The metal-chlorophyll complex was prepared from the reaction of the isolated chlorophyll and ZnCl2 (for Zn2+-chlorophyll); CoCl2.6H2O (for Co2+-chlorophyll) under reflux condition at 65 ºC with a mole ratio of 1:1. The UV-Vis spectra of the isolated products showed a hypsochromic shift to 410 nm and 660 nm for Zn2+-chlorophyll whereas the spectrum of the Co2+-chlorophyll product demonstrated the shifts to 403 nm and 661 nm. These hypsochromic shifts are proposed to be a metal-to-ligand charge transfer (MLCT) transition as a result of chlorophyll metalation. The FTIR spectra of chlorophyll and metal-chlorophyll complexes have a similar pattern despite changes in the absorption of vibrational energy in several functional groups. The absorption of the C=N group shifted from 1372 cm-1 to 1368 cm-1 for both of the complexes, the C=C group of aromatic shifted from 1451 cm-1 to 1447 cm-1 (Zn2+-chlorophyll) and from 1451 cm-1 to 1445 cm-1 (Co2+-chlorophyll), and the C=O group of ketones shifted from 1627 cm-1 to 1645 cm-1 (Zn2+-chlorophyll) and from 1627 cm-1 to 1646 cm-1 (Co2+-chlorophyll). The shift pattern of the absorption peaks on the FTIR spectra indicates the coordination of metal ions towards the N atom in the pyrrole ring in the porphyrin structure of the chlorophyll. When the isolated chlorophyll as well as the chlorphyll complexes was sensitized on the surface of TiO2, variation of bandgap energy was observed. The calculation using the Tauc Plot method resulted in the bandgap energy of films of TiO2 at 3.20 eV, TiO2/chlorophyll at 2.97 eV, TiO2/Zn2+-chlorophyll at 2.87 eV, and TiO2/Co2+-chlorophyll at 2.90 eV
