Abstract

Ecoprint is a fabric dyeing technique that utilizes natural materials such as leaves, flowers, and twigs to create unique patterns on fabric, promoting environmental sustainability. While this technique offers ecological benefits, the manual heating process used to fix the colors is often inconsistent and time-consuming. This research aims to develop a controlled heating system based on a minimum system to improve the efficiency and quality of ecoprint production. The system allows for precise temperature control at 90°C and automatic heating duration, ensuring stable temperatures and optimized time settings. The trial results indicate that the controlled heating system produces more consistent patterns, sharper colors, and reduces the risk of fabric damage compared to manual heating methods. Additionally, the system is capable of saving up to 20% in energy consumption and lowering operational costs. The implementation of this technology has a positive impact on the productivity of small and medium enterprises (SMEs), enhances product quality, and expands the market potential for ecoprint products. Therefore, this controlled heating technology not only improves production efficiency but also supports the sustainability of creative industries based on local wisdom and environmentally friendly practices

Abstract

Aspal alam yang banyak terdapat di Pulau Buton Sulawesi Tenggara biasa dikenal sebagai Asbuton diketahui memiliki deposit yang besar sehingga dapat dimanfaatkan sebagai bahan alternatif pengganti aspal minyak. Kandungan bitumen yang terdapat dalam asbuton dapat dipisahkan dengan menggunakan metode ekstraksi. Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi Natrium Tripolyphosphate (Na5P3O10) sebagai sealing agent, temperatur proses, dan jumlah kerosene terhadap %recovery bitumen dari asbuton. Tahapan pemisahan bitumen asbuton terdiri dari beberapa tahapan yaitu size reduction dari asbuton, penentuan kadar bitumen awal, proses ekstraksi menggunakan kerosene dengan durasi pengadukan selama 30 menit pada kecepatan 1000 rpm, penambahan sealing agent, pemisahan tiga fase, dan pengujian kadar bitumen yang diperoleh. Pada tahapan pemisahan bitumen ini terdapat variasi rasio kerosene:asbuton sebesar 40:60, 50:50, dan 60:40 (%w/w), konsentrasi sealing agent sebesar 0,5; 0,375; dan 0,25 (%w/w), serta temperatur proses pada 50 – 90oC. Berdasarkan penelitian yang telah dilakukan, diperoleh %recovery tertinggi sebesar 37,07%, diperoleh pada rasio asbuton:kerosene sebesar 50:50, konsentrasi Na3P5O10 sebesar 0,25%, dan suhu proses sebesar 70oC. Dengan adanya penelitian ini diharapkan dapat mendukung pengembangan produksi bitumen dalam skala industri.

Abstract

Waste from used Polypropylene (PP) and High Impact Polystyrene (HIPS) plastic is problematic in its management. The purpose of this research is to obtain the fatigue life of a mixture of used PP and HIPS plastics in its pure plastic. The research method is through the stages of mixing pure PP and 50% volume of used PP, pure HIPS and 50% volume of used HIPS, injection molding of R.R. Moore standard fatigue test specimens for pure PP, pure HIPS, pure PP + used PP, and pure HIPS + used HIPS, checking the straightness and smoothness of the molded specimen surface, fatigue testing with increasing serial loads, analysis of the bending stress curve (S) against fatigue life (N). The results showed that mixing used PP and used HIPS in pure plastic affected the fatigue life at the test speed (n)=2100 rpm for recycled PP was 9.84% shorter than pure PP, and at n=1600 rpm for recycled PP it was 9.32% shorter than pure PP, while at n=2100 rpm for recycled HIPS it was 4.45% shorter than pure HIPS, and at n=1600 rpm for recycled HIPS is 4.77% shorter than pure HIPS, while the fatigue life of pure PP is 1627704 cycles and the fatigue life of pure HIPS is 1291636 cycles or the fatigue life of pure HIPS is 20.65% shorter than pure PP, the implication of which is that the addition of used PP and used HIPS reduces the fatigue life to 9.84% for PP and 4.45% for HIPS.
