Abstract

Natural dyes are used as a non-biodegradable alternative to synthetic dyes. Fresh palm fruit bunches (FFB) are known to contain several compounds which are thought to be used as alternative natural dyes, such as: flavonoids, caratenoids and tannins. Apart from that, the use of industrial waste is an added value in this research. Fixation is the most important stage after the color dyeing process because fixation is a stage to lock and strengthen the direction of the color. The types of fixator used in this research were tawas, kapur, and tunjung. The aim of this research is to see whether CPO production sterilizer waste can be used as an alternative to natural dyes and how the type of fixator affects the dyeing results of silk fabric. The evaluation parameters of the dyeing results observed were the value of color maturity, color evenness, and washing and rubbing fastness. The results showed that the three types of fixator had an effect on the color aging value produced but did not have a significant effect on the fastness of washing and scrubbing. The highest K/S value was found in Tunjung mordant at 1.33 at ʎmax 400nm. Meanwhile for Kapur and Tawas mordant it is 0.72 and 0.71. Keywords: fixator, natural dyes, waste

Abstract

Mukena merupakan produk yang sering digunakan khususnya oleh wanita muslim untuk beribadah, dimana penggunaannya sebanyak 5 kali dalam sehari. Selain itu penggunaan mukena untuk ibadah haji atau umroh juga menjadi perhatian, karena penggunaannya di luar ruangan dan dalam jangka waktu yang panjang. Oleh karena itu sangat penting untuk memilih mukena yang baik dan nyaman digunakan. Pada penelitian ini diambil 5 buah sampel mukena yang beredar di pasaran, kemudian menguji sifat fisik kelima sampel tersebut berdasarkan SNI 8856:2020 serta kenyamanannya menggunakan alat Fabric Touch Tester (FTT), Moisture Management Tester (MMT) dan Sweating Guarded Hot Plate (SGHP). Hasil pengujian menunjukan bahwa sampel mukena CTP yang berbahan baku 100% kapas tidak memenuhi standar mutu kekuatan tarik dan stabilitas dimensi, namun memiliki nilai resistansi termal kering dan resistansi evaporasi termal yang paling tinggi. Sedangkan sampel PEP2 memiliki nilai resistansi evaporasi termal yang paling rendah, namun memiliki grade Accumulative One-Way Transport Index (AOTI) yang paling tinggi. Penelitian ini masih perlu dilanjutkan terutama untuk dilakukan pengujian kimia untuk mengetahui sifat-sifat kimia dari sampel-sampel mukena tersebut.

Abstract

Zat warna reaktif banyak digunakan untuk mencelup kain kapas. Salah satu faktor yang berpengaruh dalam proses pencelupan menggunakan zat warna reaktif panas adalah penggunaan alkali sebagai pengatur pH larutan pencelupan dan untuk proses fiksasi zat warna ke dalam serat. Campuran alkali (Na2CO3–NaOH) digunakan sebagai pemberi suasana alkali pada pH 10,5, 11, 11,5, dan 12. Hasil penelitian menunjukkan bahwa proses fiksasi zat warna dipengaruhi oleh penggunaan campuran alkali (Na2CO3–NaOH) pada pH 10,5-12. Ketahanan luntur warna terhadap pencucian, kerataan warna, kecerahan warna, dan ketuaan warna (K/S) diuji. Kondisi proses terbaik diperoleh pada pH 11. Pada kondisi tersebut, nilai ketuaan warna (K/S) sebesar 22,578, nilai kecerahan warna (lightness) sebesar 17,154, nilai kerataan warna (standar deviasi) sebesar 0,310 dan nilai ketahanan luntur warna terhadap pencucian untuk penodaan warna pada kain pelapis kapas dan wol di multifiber sebesar 5 dan perubahan warnanya adalah 4-5.

Abstract

A Characteristic often found in textile products is softness. The compound widely used as softener is silicone compound. The aim of this research is to determine the properties that will be obtained from the type of fabric being processed by comparing the use of silicon types, namely amino-propyl-functional polydimethyl siloxane (PDMS) and blocked amino silicone to each fabric. Firstly, research was conducted by varying the pH of the finishing process. Determined optimum pH will be followed by determining concentration of 15“60 g/L for each type silicone. The experiments was carried out on pad- dry- cure method. The tests carried out include fabric stiffness, tensile strength, resistance to repeated washing and heat, yellowing effect, Fabric Touch Tester and Water Contact Angle testing. It was found that there was no significant influence of pH on the use of amino-propyl-functional polydimethyl siloxane and blocked amino silicone compounds, so the next process was carried out at pH 7. Increasing the concentration of the softener will provide a better softening effect and optimum concentration at 45 g/L for both types of fabric used. Blocked amino silicone has better resistance to repeated washing compared to amino-propyl-functional polydimethyl siloxane. Heat testing shows that differences in molecular structure have no influence on both fabrics. Fabric processed using amino-propyl-functional polydimethyl siloxane provides a yellowing effect. Amino-propyl-functional polydimethyl siloxane provides good hydrophilicity. The softness value of blocked amino silicone is better performance on cotton fabric.

Abstract

Zinc oxide refers to an inorganic compound functioning as a semiconductor, recognized for its wide-ranging potential and current usage in multiple domains, such as for antibacterial purposes. The formation of zinc oxide using a sustainable synthesis route, notably via plant-based extracts, has become an attractive alternative due to its eco-conscious and economical nature. This study synthesized ZnO particles with zinc acetate as the starting material and jasmine tea extract derived from commercial teabags acting as the reducing agent in two ratio variations (Z1 and Z2). The produced particles underwent characterization via XRD, SEM-EDX, PSA, UV-Visible spectrophotometry, and their antibacterial activity was evaluated using a microdilution method to find the MIC point. The result showed that both ZnO particles adopt a wurtzite crystal, and the morphology possesses a round morphology with an estimated diameter of 500 nm. Optical properties of ZnO were also observed, yielding results of 3.9 eV and 3.2 eV. Antimicrobial potency testing was additionally performed on S. aureus and E. coli with an MIC value of 1000 ppm.
