  A woman's advice is no great thing, according to an old proverb, but he who won't take it is a fool.

  Perhaps architect Muhammad Lukman and mathematician Yun Hariyadi were aware of this when their friend Nancy Margried criticized their poor self-presentation.

  Nancy met Lukman after he held an exhibition of his mathematics-based architectural works at a

• The State Ministry for Research and Technology gave them a Rp 75 million grant early in 2008 for software development and to arrange a solo exhibition in Bandung and participate in international and national exhibitions.

  Their software, jBatik, processes traditional batik design patterns into millions of new motifs using a fractal mathematics formula.

  However, the business side of the project was still flimsy. Perhaps, Nancy said, "because we hadn't received much publicity and our batik stock was limited."

  Nevertheless, they won the 2008 Indonesian ICT Award and Unesco's Award of Excellence at the 2008 Asia Pacific ICT Awards, out of a field of 70 entrants from 10 Asia-Pacific countries.

  One of their products is now on permanent display at the Unesco Gallery in Bangkok.

  They were again hampered by financial problems, and were helped by a US$25,000 grant from Senada-USAID. After four months of development, the advanced software was launched in Bandung in May, attended by the State Minister for Research and Technology Kusmayanto Kadiman.

• Salah satu hasil desain Batik Fractal tersebut meraih penghargaan UNESCO. Selain itu, jBatik juga mengikuti beraneka kompetisi teknologi informasi. Di tingkat lokal jBatik memenangi INA-ICTA 2008 dan di tingkat Asia Pasifik jBatik memenangi APICTA 2008.

• Program jBatik dirancang dan diciptakan secara khusus untuk menghasilkan desain Batik Fractal, yaitu desain yang dibuat semirip mungkin dengan desain batik tradisional menggunakan konsep fraktal. Tentu ada masalah serius dalam penentuan semirip mungkin ini.

  Salah satu upaya jBatik agar hasilnya semirip mungkin dengan desain batik tradisional adalah dengan membuat algoritme yang mengandung: penggolongan motif batik (motif: tumbuhan, parang, geometri), mengenali unsur-unsur batik (misal: ornamen utama dan isen), serta perhitungan dimensi fraktal yang berperan sebagai alat ukur terhadap tingkat fraktal batik.
• Jika pada perangkat lunak desain grafis pada umumnya menggunakan masukan: titik, garis, dan kurva, tetapi pada jBatik masukan tersebut berubah menjadi bentuk rumus matematika sederhana: L System.
• Dengan rumus ini, titik garis dan kurva diterjemahkan menjadi variabel rumus. Selanjutnya hubungan antarmasukan tersebut akan diterjemahkan oleh L System menjadi suatu gambar tertentu.

• The recursive nature of the L-system rules leads to self-similarity and thereby fractal-like forms which are easy to describe with an L-system. Plant models and natural-looking organic forms are similarly easy to define, as by increasing the recursion level the form slowly 'grows' and becomes more complex. Lindenmayer systems are also popular in the generation of artificial life.

• using fractal as the main source of decorative patterns, the hybrid batik that is emerged from the acquisition of L-System Thue-Morse algorithm for the harmonization within the grand designs by using both fractal images and traditional batik patterns, and using the random image tessellation as well as previous tiling algorithms for generating batik designs.

• Barnsley generated the fractal   pattern that's now known as Barnsley's Fern. It's supposed to   resemble the Black Spleenwort, Asplenium adiantum-nigrum.   You can find numbers of references to Barnsley's Fern on the Internet.   It's usually depicted like this:

    

• FS fractals, as they are normally called, can be of any number of dimensions, but are commonly computed and drawn in 2D. The fractal is made up of the union of several copies of itself, each copy being transformed by a function (hence "function system")
