Abstract

This training was designed to introduce ecoprint techniques to members of the Women's Dharma Association of the West Papua Provincial Forestry Service, emphasizing its potential as a community-based business opportunity. The activity utilized natural materials readily available in the surrounding environment, such as butterfly pea leaves and flowers, teak leaves, and other local foliage. The training was conducted in stages, beginning with an introduction to the basic concepts of eco-printing, followed by hands-on practice using two main techniques: pounding and steaming. These techniques were applied to cloth tote bags and ceramic mugs. The results showed that participants demonstrated a higher level of proficiency in producing eco prints using the steaming technique compared to the pounding method.

Abstract

Pada penelitian ini, telah dilakukan pengujian tahap awal sifat tahan api batu bata yang dibuat dari tanah merah dan alumina (Al2O3) sebagai bahan paduannya. Bahan Al2O3 diperoleh dari ekstraksi limbah bungkusan susu formula, sedangkan tanah merah yang digunakan berasal dari daerah distrik Warmare, Manokwari Barat, Papua Barat. Analisis kandungan tanah merah menggunakan XRF diperoleh komponen utama berturut-turut 39.57%, SiO2, 30,94% Al2O3 dan 23,73% Fe2O3. Proses ekstraksi dilakukan dengan metode gravimetri, melarutkan limbah alumunium dalam larutan HCl 18%, selanjutnya pengendapan Al(OH)3 menggunakan larutan Amoniak 25%. Konversi endapan Al(OH)3 menjadi Al2O3 dengan proses kalsinasi pada suhu 800 °C, hasil analisis XRF terhadap ekstrak yang diperoleh menunjukan 89.1% Al2O3, 3.95% SiO2, 3.06% NA2O dan 1.79% MgO. Batu bata dengan kandungan Al2O3 30% dan 50% menunjukan sifat tahan api setelah dibakar pada suhu 300 °C dan 500 °C karena batu bata tersebut tidak mengalami keretakan.
