Use of synthetic dyes for dyeing of textile fabrics is most problematic environmental concerned for textile industry. The demand of natural colourants for the dyeing of textile fabrics has been increasing. Thus, sustainable novel technologies for textile dyeing are needed that utilize improved colour strength and enhanced performance characteristics of the fabric. This study attempts to highlight the possibility of using cochineal natural dye in the printing of polyester fabrics after surface modification by O2/Ar plasma treatment. The colour strength, air permeability, crease recovery angle of printed fabrics, colour fastness to rubbing, washing and light, were also studied. The surfaces of untreated and plasma-treated polyester fabrics were analysed by SEM to compare the morphological changes. Surface roughness and cracks were indicated after the plasma pretreatment. The results indicated that plasma treatment could improve the printability of polyester fabric compared with untreated samples, with enhanced the adhesion and penetration of printing paste to the surface. The air permeability of printed fabrics has decreased, while the angle of crease recovery has increased. The fastness properties of printed samples were found suitable to very good.

Sweet potato leaf (Ipomoea Batatas) is a potential agricultural waste is used as animal feed to Goat crossbreed of Ettawa. Sweet potato leaf (Ipomoea Batatas) has a high enough protein content (> 20%), so it can be used as a source of protein goat crossbreed of Ettawa. This research aims to determine the effect of feeding of sweet potato leaves (Ipomoea Batatas) as feed on goat body weight of goat crossbreed of Ettawa. This research has been conducted in February to March 2015, located in Wonua Raya village, Toari district, Kolaka Regency. This research uses 12 goats crossbreed of Ettawa which is divided into 12 plots of cages. In this research, four levels of feeding treatment were applied: regular feed/Gamal leaf (R0), 90% Gamal leaves + 10% sweet potato leaves (R1), 85% Gamal leaves + 15% sweet potato leaves (R2), 80 % Leaf Gamal + 20% sweet potato leaves (R3). The results showed that the use of sweet potato leaves on weighing 15 days did not significantly affect the rate of body weight and had a significant effect on considering at day 30 (p

EFFECT OF PARTLY SUBSTITUTION OF BASAL DIET WITH SWEET POTATO VINES (Ipomoea batatas)  MEAL ON ENERGY AND PROTEIN DIGESTIBILITY OF PIGS. Pork is one of the meat producer animals that can contribute to satisfy animal protein requirements. Sweet potato vines is considered as an agricultural waste product and can be used as feedstuff for pigs. The present  study was conducted to determine the utilization of sweet potato vines  substituting basal diet on energy and protein digestibility of finisher pigs. Five ‘Duroc X Spotted Poland China’ castrated male pigs, aged 3.5 to 4.0 months with an initial body weight 50 kg (±2.5 kg) were assigned to four treatments as follow: R0 = 100% basal diet + 0% sweet potato vines meal; R1 = 92.5% basal diet + 7.5% sweet potato vines meal; R2 = 85% basal diet + 15% sweet potato vines meal; R3 = 77.5% basal diet + 22.5% sweet potato vines meal; and R4 = 70% basal diet + 30% sweet potato vines meal. Parameters measured were: energy and protein digestibility. Research reasults showed that there is no significant differences  (P > 0.05) among treatments on energy and protein digestibility of pigs in the present study. This indicated that utilization of sweet potato vines meal up to 30% replacing basal diet did not affect digestible energy and protein of finishing pigs. It can be concluded that substituting basal diet with sweet potato vines meal up to 30% has no negative effect on energy and protein digestibility of finishing pigs.   Keywords: Sweet potato vines, energy digestibility, protein digestibility, pigs

ABSTRACTColor is one of the determining factors in quality in cosmetics. Usage of synthjetic dye in blush on could cause irritation on facial skin, irritation on respiratory tract, and damage to the liver. The aim of this study was to formulate and to evaluate the physical characterization of the blush on preparation by using natural dye from the purple sweet potato extract (Ipomoea batatas L.) with the variation concentration on 20%, 25%, and 30%. Formulation of stick blush on used fusion method. The extract is obtained by means of maceration using ethanol solvent 96%. Organoleptics, color homogeneity, pH, stability toward light, polish test and preference test were included in the evaluation of the physical properties of the preparation. The result of the physical properties test showed the preparation’s color ranged from pale purple to dark pink, a distinctive scent of oleum rose perfume, soft texture, all preparation had homogenous arrangement, pH value of the preparation  ranged from 6.00-6.61, the best polish were on concentration 25% and 30% this is characterized by a one-time polishing of the ready has given a clear color when polished on the skin of the back of the hand, color observation at all preparation did not had any changes in 14 days, and the preferred preparation by the panelists were the preparation with pigment concentration of 20%, 25% and 30%. It can be concluded that the combination of the purple sweet potato extract (Ipomoea batatas L.) can be used as a natural dye in blush on preparation. Keywords: Ipomoea batatas L., Blush on, Formulation  ABSTRAK Warna adalah salah satu faktor penentu mutu kosmetika. Penggunaan pewarna sintesis pada perona pipi dapat menyebabkan iritasi pada kulit wajah, iritasi pada saluran pernapasan, dan kerusakan pada hati. Tujuan Penelitian ini untuk memformulasi serta mengetahui evaluasi fisik sediaan perona pipi dengan memanfaatkan pewarna alami dari ekstrak ubi jalar ungu (Ipomoea batatas L.) dengan konsentrasi 20%, 25% dan 30%. Pembuatan sediaan perona pipi menggunakan metode peleburan. Evaluasi fisik sediaan meliputi organoleptik, homogenitas warna, pH, stabilitas terhadap cahaya, uji poles dan uji kesukaan.

Textiles sectors serve up the outfit needs of every day and this industry plays a major role in the economy of the country. All the textile fabrics are either natural or synthetic fibers or a blend of both. Different types of dyes are used for different kinds of fabrics depending on the nature and type of the fabric to be dyed, to impart color, modify the fabric to make them more attractive and astonishing. In short, the introduction of synthetic dyes resulted in the demise of a massive natural dye industry. So, it's necessary to classify the different types of dyes with the increase in the number of types and varying dyeing properties so that this would be a best way to understand the different types of dyes, their applicability, fastness and other properties. In this article, a source for the beginners is provided to understand different kind of the textile fabrics and their importance as well as their drawbacks, dyes and their various types, their interaction with the corresponding fabric, their color strength and color fastness properties.
