Abstract

Pengental memegang peranan penting dalam tingkat keberhasilan kualitas pencapan. Pada pencapan zat warna reaktif hasil optimum diperoleh dengan penggunaan campuran natrium alginat dan CMC. Pengental jenis natrium alginat memiliki waktu simpan yang singkat. Oleh karena itu, dalam penggunaannya perlu ditambahkan zat anti bakteri sehingga viskositas pengental tetap stabil. Salah satu zat anti bakteri alamiah yaitu daun sirih hijau. Sebelum digunakan, daun sirih hijau diekstraksi sampai diperoleh massa kental daun sirih hijau. Pengujian aktivitas anti bakteri dilakukan sebelumnya dan menunjukkan bahwa ekstrak daun sirih hijau dapat menghambat pertumbuhan bakteri dalam pengental induk. Penelitian dilakukan dengan penambahan ekstrak daun sirih hijau ke dalam pengental induk campuran dengan konsentrasi 0, 2, 5, dan 8 g/kg, yang disimpan dalam waktu kurun waktu 0 sampai 7 hari. Hal ini dibuktikan pada hasil uji aktivitas antibakteri dan viskositas pengental induk yang stabil hingga hari ke-7, berbeda dengan tanpa penggunaan ekstrak daun sirih hijau yang viskositasnya makin menurun drastis tiap harinya. Pada penggunaannya, makin banyak konsentrasi ektrak daun sirih hijau yang digunakan maka viskositas makin stabil dan ketajaman motif pun makin baik namun ketuaan warna makin menurun.

Abstract

PT X yarn warehouse have various leftover yarns of different types, colors, and yarn numbers. These leftover yarns can be reused for small-scale production. However, the problem in PT X's yarn warehouse is the difficulty in finding yarns due to their stacked positions and the lack of identification on the yarn piles. As a result, the search time for yarns in the warehouse becomes lengthy, affecting production efficiency. The average search time for one leftover production yarn is 20 minutes and 27 seconds. This study aims to design and implement a QR Code system for organizing raw materials in the yarn warehouse to reduce yarn search time. The research method begins with data collection of the yarns in the warehouse. Next, warehouse organization is carried out by grouping and placing the yarns based on type, color, and yarn number on designated racks. The collected data will form a database in an addressing document in Google AppSheet. Warehouse employees can do scanning the code and be directly directed to a specific page in Google AppSheet, Google Drive, or Google Spreadsheet to quickly obtain yarn location information. The study results show that the implementation of QR Codes leading to a reduction in search time until 98,45%. The average of searching time before the implementation is 20 minutes and 27 seconds and reduced become 19 seconds to locate the yarn position.

Abstract

Polyester-cotton fabric was dyed using disperse and reactive dyes. Dyeing of polyester using disperse dyes is commonly performed under acidic pH condition. However, reactive dyes dyeing process requires an alkaline pH condition so that the dye can be fixed on the cotton fiber. The usage of strong alkaline can cause erosion of the surface of the polyester fiber and result in a decrease in tensile strength. This research discusses about alkaline usage in the dyeing process of polyester-cotton fabric with disperse and reactive dyes to obtain good dyeing quality without reducing the tensile strength value of the fabric. The type of alkaline used was Na 2CO3 with concentration of 10 g/L (pH 11), 15 g/L (pH 12) and 20 g/L (pH 13). The dyeing process is carried out continuously using one bath two stages (1B2S). The characterization carried out on the dyeing samples were analyzed by tensile strength testing, color strength, color evenness using spectrophotometer, and color fastness to rubbing test. The results of the research showed the best condition under pH 12 with the usage of 15 g/L Na2CO3 had greater value of 39 kg for warp tensile strength, 28.08 kg for weft tensile strength, 12.69 of color strength, 1.17 of color evenness, color fastness to wet rubbing of 4 and color fastness to dry rubbing of 4-5.

Abstract

Masker menjadi salah satu bagian yang penting dan melekat pada wajah selama beberapa tahun terakhir. Bahkan hingga saat ini, Masker sudah menjadi kebutuhan dalam rangka menjaga kualitas udara yang kita hirup. Masker kain menjadi pilihan ekonomis karena dapat dipakai berulang-ulang namun penggunaan dalam waktu yang lama memberikan dampak yang kurang baik terhadap kulit wajah penggunannya. Modifikasi bahan masker menjadi pilihan untuk mengurangi dampak yang kurang baik terhafap wajah. Modifikasi permukaan menjadi salah satu pilihan ketika bahan tettron cotton (TC) sebagai bahan yang memiliki stabilitas dimensi yang baik dimodifikasi sifatnya untuk menaikan sifat adhesive nya. Paparan Plasma menjadi pilihan modifikasi yang ramah lingkungan untuk merubah sifat permukaan kain TC. Efek modifikasi permukaan akibat paparan plasma pijar diharapkan mampu menaikkan sifat adhesive, sehingga kain TC (tetteron cotton) yang semula memiliki sifat hidrofobik berubah menjadi hidrofilik dan dapat dilakukan penambahan sifat antibakteri. Dengan di tambahkannya sifat anti bakteri kain TC tidak hanya dapat menyaring udara sebagai bahan masker kain tetapi juga menjaga kulit wajah dari bakteri yang timbul akibat kelembaban selama penggunaan masker. Variasi yang diberikan dengan waktu proses treatment plasma yaitu 1.5, 2.5, 3.5, 4.5, 5.5 menit dengan jarak 4 cm. Kemudian variasi jarak yaitu 4 cm, 4.5 cm, 5 cm, 5.5 cm dan 6 cm pada waktu 5.5 menit selama pengujian. Hasil kebaharuan dari penelitian ini adalah dihasilkannya suatu produk masker kain yang memiliki sifat antibakteri dengan metode Coating Ekstrak Daun Eucalyptus Globulus serta berfungsi sebagai penghambat bakteri yang berpontensi masuk ke saluran pernapasan.

Abstract

Treating wastewater from polyester dyeing processes using disperse dyes is essential for environmental conservation. Among various treatment methods, electrocoagulation presents a promising alternative for textile effluent remediation. This study developed predictive models using Response Surface Methodology (RSM) to optimize the electrocoagulation process by examining the effects of process duration (0-30 minutes) and applied voltage (5-9 Volts) on pH and electric current. Results demonstrated that the RSM model achieved excellent predictive accuracy for electric current (R² = 0.9786), while the pH model showed moderate correlation (R² = 0.6013). Statistical validation confirmed model reliability through adjusted R², predicted R², and adequate precision values. The research identified optimal time-voltage parameter ranges for experimental waste treatment applications. Both independent variables significantly influenced the observed responses, with voltage exerting a dominant effect on electric current generation during electrocoagulation. These findings contribute to the development of more efficient treatment processes for textile wastewater and align with previous studies highlighting electrocoagulation's effectiveness in pollutant removal from industrial effluents.

Abstract

The removal of size from sarong woven fabric that has undergone yarn dyeing is very important to prepare the fabric for the next process. The handle of the sarong fabric will become stiff if the size removal process is not done perfectly. The size used to increase the strength of the yarn in the weaving of woven fabrics uses a synthetic polyvinyl alcohol size type. The size removal method is carried out using hot water by varying the process temperature of 70o C, 80o C, 90o C, and 100o C. The results of the starch removal process were evaluated for absorbency, stiffness and color difference values. The results showed that increasing the temperature of the size removal process significantly increased the effectiveness of polyvinyl alcohol removal. The optimum temperature for size removal was at 100o C, resulting in a weight reduction of 9.62%. The absorption test increased by 69.33% or 18.4 seconds. Fabric stiffness decreased drastically, with the largest decrease in stiffness of 63.15% in the warp direction and 61.3% in the weft direction. Color difference measurements showed the smallest ΔE value among other size removal temperature variations with a value of 0.36.
