3.2. Using of Lower Resin and Process Positive Moulds
The study on the use of low resin with a “positive mold” on disc brake pads show that fading does not occur when using the brake lining. This is due to positive mold process is the
best way to produce the disc pad and this process is widely used by brake manufacturers original equipment manufacturerOEM.During the process of positive mold hot press, the
brake lining material placed into the cavity of the dies hot press and then pressed so that the average density occurs on the brake. Brake product that uses the system process mold
flash with resins and brake material content must be excessive so that the resin can flow out. High resin content can easily lead to tension brake due to high temperatures fading
when braking occurs. Due to this fading can cause increased braking distances of 50 or more, resulting in an unavoidable accident due to tension brake. This can happen on the
brake canvas made from raw asbestos brakes with high resin consumption between 15 - 20. Non-asbestos brake canvas which only added to the resin content of 9-10, high
temperature braking can anticipate of tension brake problems or canvas fading brakes.
4. CONCLUSION
1. The addition of non-wood pulp fiber as a substitute for asbestos in vehicle brake canvas obtained the optimum composition of pulp fiber .

2. Pulp fiber brake for two wheeled vehicles produce good friction power quality and has a heat resistance up to 300
o
C braking effect on the optimum composition of the pulp. 3. Optimization of fiber pulp manufacture brake lining can be implemented with the addition
of a number of other filler materials in accordance with the composition of the pulp. Pulp fiber brake lining type A and type B is the experimental result that has been applied to
the automotive industry scale. 4. Nonwood pulp fibers can be used as a filler canvas brakes as a replacement of asbestos
fibers. Trial results on an industrial scale by making 1000 pairs of brake drum type and disc type has been implemented in the automotive industry.
5. Test results of pulp fiber brake canvas products for two-wheeled vehicles, in compliance with SNI 09-0143-1987 and meet the commercial brake canvas. Patents canvas pulp
fiber brake for vehicles have been registered as a Patent No.ID. P0029623 in Indonesia.
6. Socialization and installation of fiber pulp canvas brakes on two wheels vehicles in the community such as students, households, workers and taxi motor has been implemented
with encouraging results. ACKNOWLEDGMENTS

ABSTRAK Pemanfaatan kembali sisa kain perca menjadi produk fashion bernilai seni patchwork aesthetic
dengan teknik patchwork kembali marak di Kota Bandung dan berbagai kota kreatif lainnya di Indonesia. Teknik penggabungan perca bukan hal yang baru, namun tidak semua orang mampu
membuat motif produk perca bernilai seni patchwork aesthetic. Perlu budaya kreatif dalam menggabungkan potongan kain menjadi motif tertentu yang bernilai ekonomi. Selain mengurangi
limbah kain, produk fashion patchwork ini membuka lapangan kerja padat karya, sumber pendapatan dan ekspresi seni pembuatnya bahkan sebagian orang menggunakannya untuk terapi. Penelitian ini
menggunakan pendekatan kualitatif dengan teknik wawancara pada desainer graphic fashion yang memiliki bisnis patchwork di Bandung. Pembuatan produk secara eksklusif dengan satu motif dan satu
warna untuk satu barang dengan lama pengerjaan dari satu minggu hingga 3 bulan tergantung pada tingkat kesulitan motif dan ukuran. Kisaran harga dari Rp. 75.000,- s.d Rp. 3.000.000,- membuktikan
bahwa inovasi frugal bekerja pada limbah kain sehingga bernilai ekonomi kreatif. Kata Kunci: budaya kreatif, inovasi frugal, Kota Bandung, kriya tekstil
