Abstract

Inovasi merupakan kunci utama dalam perkembangan ekonomi. Tren industri mulai menggunakan mesin otomatis. Dampak  pengangguran sangat berpengaruh terhadap pertumbuhan ekonomi menjadi tidak stabil. Untuk itu, perlu terjalinnya “link and match” antara industri dan dunia pendidikan Perguruan Tinggi sebagai penyedia tenaga kerja penting melakukan kajian untuk menghadapi tantangan tersebut. Pada studi kasus kali ini adalah industri printing (grafika). Tujuan penelitian ini adalah adalah mengetahui indikator yang valid dan reliable pada pasar tenaga kerja di Industri Percetakan Jabodetabek. Metode yang digunakan penelitian ini adalah  analisis multivariate menggunakan cluster analysis. Pengumpulan data dilakukan menggunakan wawancara dan kuesioner dengan responden adalah industri printing. Adapun aspek yang diukur sesuai dengan key indicators of Labour Market (KILM) edisi 9 oleh ILO.  Hasil penelitian menunjukan terdapat 3 cluster industri dengan karakteristik masing-masing yang dapat diinterprestasikan menjadi cluster introduction, growth dan mature.

Abstract

Batik is a world-recognized cultural heritage of Indonesia, but the batik industry stillrelies on synthetic dyes that pollute the environment, especially water pollution. Thisstudy aims to develop natural black batik ink from coconut fiber through pyrolysis andanalyze its color density. The process is carried out by heating coconut fiber at 150-250°C to produce charcoal, which is then pulverized into pigments. The pigments weremixed with distilled water (variation of 1-7 g pigment and 6-12 mL distilled water) andtested for density using a spectrodensitometer. The results showed that the formulationof 6 grams of pigment and 11 mL of distilled water produced the highest concentration(2.68). The average concentration of all samples reached 2.57, indicating theconsistency of pigment quality. This study proves that the ratio of pigment and solventaffects color density, while providing an environmentally friendly solution by utilizingcoconut fiber waste as a natural dye with economic value.

Abstract

This study investigates the effect of gum arabic composition on the solid content of organic ink made from sappan wood (Caesalpinia sappan) as a natural dye. The study uses a quantitative method with an experimental approach. The main focus of this research is the solid content test, which is important for determining the quality and durability of organic inks. Variations of gum arabic were used as a binder in the ink formulation, with the tests conducted using screen printing on cotton combed fabric. The results indicate that the lower the composition of gum arabic used, the higher the solid content obtained. The ink with the lowest gum arabic composition (5 grams) produced the highest solid content at 78.79%, compared to 75.00% for 10 grams and 60.00% for 15 grams of gum arabic. Additionally, physical characteristics such as color intensity and viscosity were also influenced by the solid content, with darker colors and thicker textures observed as the solid content increased. These findings contribute to the development of more eco-friendly organic inks with improved stability and performance, supporting the sustainability trend in the printing industry.
