Abstract

The research about utilization of extracts areca nuts (Areca catechu L.) as natural dye on sasirangan using whiting mordan 1% (w/v) was carried out. The results showed that the extract of areca nuts can be used as a dye on sasirangan with the types of cloth ware cotton, silk, semi-silk and the colour was red guava. The dye yield of areca nuts was resulted in 34.43%. The optimum mass of natural dye on cotton was adsorbed about 1,90% in the concentration of dye solution 1:50 (g/mL), on silk about 0,46% in the concentration of dye solution 1:100 (g/mL), and on semi-silk about 0,64% in the concentration of dye solution 1:75 (g/mL). The quality color fastnessin detergents 1% were showed the best value on cotton about 23% in the concentration of dye solution 1:50 (g/mL), on silk about 66% in the concentration of dye solution 1:75 (g/mL), and on semi-silk about 34% in the concentration of dye solution 1:100 (g/mL). The results of dray and wet brush resistance showeda good values for all treatment with the avaregge staining scale values were 3-4. The qualities of color intensity for cotton and silk showed that the higher mordant concentration, washing fastness becomes better, and color is deeper. The quality of color intensity optimum for semi-silk was showed  in the concentration of dye solution 1:75 (g/mL). The optimal result for cotton is in the used of day solution 1: 100 (g/mL), silk 1:75 (g/mL), and semi-silk 1:75 (g/mL) which the whiting mordant concentration was used 1% for all treatment.Keywords: arace nuts (Areca catechu L.), whiting mordant, sasirangan dyeing

Abstract

Oil palm empty fruit bunches and water hyacinth have not been widely used, especially in South Kalimantan. These materials were known containing macro elements that are needed by plants. This research was conducted to study potential of oil palm empty fruit bunches and water hyacinth as raw material for organic fertilizer. The effect of ashing temperature variations (500°C; 750°C; 1000°C) on the macro nutrients content (N, P2O5, and K2O) have been studied. The result showed that the characterization of empty fruit bunches and water hyacinth have the highest P2O5 and K2O content, whereas the content of nitrogen was still lowest. The treatment of ashing temperature was effect on improve total content of N, P2O5 and K2O. The highest nitrogen contents in empty fruit bunches and water hyacinth obtained on ashing temperature 500oC. The highest P2O5 contents in empty fruit bunches obtained on ashing temperature 1000oC and water hyacinth obtained on ashing temperature 750oC. The highest K2O contents in empty fruit bunches obtained on ashing temperature 750oC and water hyacinth obtained on ashing temperature 500oC. Ash of oil palm empty fruit bunches and water hyacinth was potentially as a source of nutrients P2O5 and K2O for organic fertilizer, but less potential as a source of nitrogen.Keywords: oil palm empty fruit bunches, water hyacinth, raw material, organic fertilizer

Abstract

Seiring banyaknya permintaan konsumen akan pakaian menyebabkan banyaknya jenis usaha pembuatan serta penyediaan pakaian berkembang di masyarakat. Umumnya mereka hanya menyediakan jasa pembuatan T-shirt, jaket, dan kemeja, hanya masih sedikit wirausaha yang menyediakan jasa pembuatan jas lab, sehingga berdampak sulitnya pelajar khususnya mahasiswa dalam memenuhi kebutuhan jas lab. Tujuan penulisan ini adalah mengetahui peluang usaha pembuatan jas lab di Bali, sehingga nantinya dapat membantu memenuhi kebutuhan jas lab mahasiswa serta pelajar SMP-SMA. Berdasarkan perhitungan harga yang dilakukan, dengan berwirausaha menggunakan sistem suplier ini, dihabiskan biaya pembuatan jas lab untuk bahan kain Nagata Drill sebesar Rp 76.000 dan bahan kain Oxford Rp 56.000 per potong. Harga jualnya adalah Rp 90.000 untuk jenis kain Nagata Drill dan Rp 70.000 untuk jenis kain Oxford, dengan harga tersebut diperoleh keuntungan Rp 14.000 per potong. Berdasarkan hasil survei harga rata-rata jas lab yang ada adalah Rp105.000. Hal ini menunjukkan prospek yang menjanjikan untuk usaha selanjutnya sebab dapat ditawarkan harga yang bersaing di pasaran.
