“…Semakin besar konsentrasi fiksator tawas maka pH semakin menurun yang diartikan semakin asam. Pigmen zat warna dalam kondisi pH 2.5-7 akan menghasilkan warna kuning yang cerah, sedangkan pada pH basa akan menghasilkan warna kecoklatan (Winarto, 2004;Wang et al, 2009;Wang et al, 2014). Dapat disimpulkan bahwa konsentrasi pada fiksator kapur memiliki nilai a* tertinggi yang diartikan kain warna yang dihasilkan cenderung mengarah pada warna merah.…”

ABSTRAKPenelitian ini adalah untuk mengetahui pengaruh jenis dan konsentrasi fiksator terhadap kualitas pewarna alami dari daun mangga arum manis yang diaplikasikan pada kain. Penelitian ini menggunakan Rancangan Acak Tersarang dengan dua faktor. Faktor utama adalah jenis fiksator yaitu tawas, garam, dan kapur tohor, sedangkan faktor tersarang adalah konsentrasi pada setiap fiksator. Konsentrasi fiksator terdiri dari tawas dengan konsentrasi 10% dan 15%, garam 10% dan 12%, serta kapur tohor 8% dan 10%. Sifat setiap fiksator dapat mempengaruhi arah warna serta ikatan antar serat dan pigmen warna. Pada fiksator tawas, perlakuan terbaik diperoleh pada konsentrasi 10% dengan nilai a* 11.63, nilai b* 22.3, dan nilai L* 63.13. Pada fiksator garam, perlakuan terbaik terdapat pada konsentrasi 10% dengan nilai a* 9.87, nilai b* 30.1, dan nilai L* 62.07. Pada fiksator kapur tohor, perlakuan terbaik terdapat pada konsentrasi 10% dengan nilai a* 14.57, nilai b* 29.3, dan nilai L* 56.8 PENDAHULUANTanaman mangga (Mangifera indica L.) merupakan tanaman holtikultura yang mempunyai nilai ekonomis tinggi karena memiliki kandungan gizi yang cukup tinggi bagi kesehatan manusia. Luas lahan tanaman mangga di Indonesia mencapai 18354990 km 2 . Luas lahan terbesar terdapat pada Jawa Timur dengan luas lahan 55955299 km 2 dan disusul oleh Jawa Barat dengan luas lahan 3151115 km 2 (BPS, 2015). Setiap bagian tanaman mangga dapat dimanfaatkan, salah satunya adalah bagian daun. Mangga (Mangifera indica L.) memiliki banyak varietas, akan tetapi varietas mangga arum manis adalah varietas yang banyak dibudidayakan. Daun mangga mengandung pigmen warna flavonoid yang akan menghasilkan warna hijau kekuningan (Pujiarti et al., 2009). Pigmen tersebut dapat diaplikasikan sebagai pewarna alami pada kain.

“…Different shades and tones might be obtained from a single dye source by application of the pH value of its bath (Wang et al, 2014;Ren et al, 2016;Suciatmih and Yuliar, 2018) and mordant (Sangeetha et al, 2015;Suciatmih and Hidayat, 2017;Suciatmih and Yuliar, 2018). The effect of the dyeing pH can be attributed to the correlation between the pigment structure and cotton cloth.…”

This study aimed to examine the dyes production of mixed Aspergillus and Paecilomyces on different culture conditions and evaluate the combination between culture and dyeing conditions on cloth color by the fungal dyes. The different media consist of mineral salt glucose (MSG) medium and mineral salt sucrose (MSS) medium were evaluated. Additionally, different culture conditions such as C and N sources, incubation temperature, and pH of the media were evaluated together with variation of dyeing conditions including pH and mordants. The result showed that different culture conditions on media and the combination of those with dyeing conditions produce distinction colors on the fabric. The variation of dyed colors on the fabric was related to the dyes concentration produced by combination treatment of culture condition and dyeing pH. However, the effect was not observed on the combination between culture condition and mordants. Combination of culture and dyeing conditions on cloth color dyed with mixed fungi dyes generated various cloth colors, adding a color variation on textile dyeing.

“…The probable reason could be that anthocyanin pigment present in grape seed extract has the minimum staining time of 120 minutes, [19] and chlorophyll pigment present in wheat grass extract has a minimum staining time of 105 minutes. [20] The application time required for the present protocol was far less than staining time of antioxidants.…”

Background and Aim: The bleached enamel surface requires application of antioxidant as there will be continuous release of free oxygen radicals. It would be beneficial if remineralizing agent which is recommended after bleaching also provides an antioxidant therapy. The natural antioxidants are colored. Hence, the aim of the present study was to evaluate the effect of natural antioxidants on the shade of the bleached enamel. Materials and Methods: Thirty single rooted maxillary anterior teeth were selected for the study. For all the samples middle third portion of the labial surface of the teeth was standardized using computerized cellophane stickers. Bleaching was carried out with 22% Carbamide peroxide gel (Philips Zoom Nite White). Based on the type of antioxidant solution application, samples were divided into three groups of ten samples each. Group I control (n=10) Group-II (n=10) 10% wheat grass solution (Sresta natural Bio products, India) Group-III (n=10) 5% grape seed extract (Zenith nutrition, Medizen Labs Pvt.Ltd, India). L, a, b values were recorded with spectrophotometry (Vita Zahnfabrik H. RauterGmbH & Co. KG,Bad Sackingen, Germany) thrice for each sample at the three respective time periods i.e at baseline, after bleaching and after antioxidant application. Results: ΔE values were subjected to statistical analysis using one way ANOVA with p>0.05 and the results were tabulated. It was observed that there was statistical insignificant difference between the groups with a p value of 0.295(p>0.05). Conclusion: The antioxidants 5% grape seed extract and 10% wheat grass extract did not affect the shade of the bleached enamel. Keywords: tooth bleaching, antioxidant, shade, spectrophotometry
