Abstract

Pigmen berperan sebagai sumber utama pembentuk warna pada tinta cetak. Keberadaan tinta dalam proses pencetakan sangat penting karena berfungsi menghasilkan tampilan warna pada berbagai jenis media, seperti kertas, tekstil, maupun plastik. Selain memberikan nilai estetika, tinta juga berkontribusi terhadap kualitas dan daya tahan hasil cetak. Variasi konsentrasi pigmen dapat menyebabkan perbedaan nilai warna yang dihasilkan, sehingga diperlukan formulasi yang tepat untuk mengatasi permasalahan tersebut. Penelitian ini bertujuan untuk menganalisis pengaruh konsentrasi pigmen terhadap karakteristik warna bluish shade tinta fleksografi pada substrat LDPE White menggunakan parameter CIELAB dan ΔE. Metode penelitian dilakukan dengan memvariasikan konsentrasi pigmen merah pada lima formulasi tinta, sedangkan komposisi varnish dijaga tetap. Setiap formulasi dicetak menggunakan metode proofing hand anilox. Pengujian dilakukan untuk mengetahui kecenderungan perubahan arah warna dan intensitas warna hasil cetak menggunakan spektrofotometer berdasarkan parameter L, a, b, dan ΔE. Pengujian ini juga dilakukan untuk mengevaluasi tingkat kesesuaian warna terhadap standar yang ditetapkan pelanggan. Hasil penelitian menunjukkan bahwa variasi konsentrasi pigmen sebesar 61–65 gram memberikan pengaruh terhadap nilai CIELAB dan ΔE yang dihasilkan. Formulasi T4 dengan konsentrasi pigmen 64 gram menghasilkan karakteristik warna yang paling mendekati standar, dengan nilai L sebesar 46,32, a sebesar 67,74, dan b sebesar -9,82 serta nilai ΔE terendah sebesar 0,89. Hasil ini menunjukkan bahwa konsentrasi pigmen berperan dalam pembentukan karakter warna bluish shade pada tinta fleksografi dan memengaruhi tingkat perbedaan warna yang dihasilkan pada substrat LDPE White.

Abstract

Commercial calendar production typically uses virgin paper, contributing to increased wood fiber consumption and waste. This condition encourages the development of environmentally friendly alternatives using recycled materials. This study aims to produce a desk calendar made from recycled paper mixed with butterfly pea flowers as a natural dye and aesthetic element, and to evaluate the effectiveness of its production process.The study involved several stages, including recycled paper processing (soaking, pulping, mixing with butterfly pea petals, sheet forming, drying, and cutting) and calendar assembly (cutting carton board, applying linen cover, printing A5 calendar design, punching spiral holes, installing spiral wire, and attaching a 7×7 cm glass component). The production process was evaluated using the 5W1H framework to identify key factors, constraints, and methodological effectiveness.The resulting calendar displays natural visual characteristics,coloration from butterfly pea pigment, and an additional functional element through the integration of a small glass piece. Analysis shows that paper-making is the most time-consuming stage, while the assembly process is relatively efficient.The recycled paper calendar incorporating butterfly pea flowers was successfully developed as an eco-friendly product with strong aesthetic value and added functionality. Further improvements are recommended for achieving consistent paper thickness and optimizing drying time.

Abstract

The increasing volume of cellulose-based waste has intensified the need to utilize paper waste into products with higher functional value. This material has considerable potential to be developed into functional products when processed through a systematic design approach. This study aims to develop Ecovault, an environmentally friendly storage product made from cardboard and paper pulp, using the Design Thinking approach. During the empathize stage, a survey was conducted to identify user needs, which indicated strong support for the use of recycled materials. The define stage identified two main issues: the low utilization of paper waste and the demand for small-sized storage products with an attractive appearance. The initial concept was realized in the form of a flower-pot-shaped storage through 3D rendering and subsequently tested through prototype development. The first prototype experienced structural issues, leading to a design revision by changing the pot shape from cylindrical to box-shaped. This modification improved the stability, strength, and structural neatness of the final prototype. The results demonstrate that paper waste can be transformed into functional and aesthetic storage products through an appropriate design approach.
