ABSTRAK UD Melati Mekar Mandiri adalah sebuah perusahaan pengrajin yang bergerak di bidang kain tenun gedog dan batik tulis. Perusahaan yang terletak di Kerek, Jawa Timur ini mempunyai pengrajin, baik yang mengerjakan tenun batik di perusahaan maupun di rumah. Adapun tahap pengerjaan yang dilakukan dilakukan dari kain menjadi batik yaitu : mencuci kain yang telah ingin dibatik, pembatikan, dan pewarnaan. Banyaknya tahapan produksi dan persaingan yang sangat ketat, sehingga dibutuhkan perencanaan untuk mementukan jumlah produksi. Hal ini dilakukan agar dapat memenuhi permintaan pasar sehingga jumlah kebutuhan konsumen dapat terpenuhi. Kegiatan dalam melakukan persediaan barang yang terlalu besar harus dihindari karena merupakan sebuah pemborosan/kerugiaan. Untuk itu dibutuhkan sebuah sistem untuk memperkirakan jumlah produksi agar perusahaan dapat memenuhi permintaan konsumen. Pengambilan data akan dilakukan dengan studi kasus di UD Melati Mekar Mandiri. Metodologi dalam pembangunan sistem menggunakan metodologi waterfall. Penelitian ini menggunakan data jumlah permintaan, jumlah persediaan, jumlah tenaga kerja sebagai variabel inputan dan data jumlah produksi sebagai variabel outputnya. Tahap pertama penyelesaian produksi barang dilakukan dengan menentukan variabel input dan variabel output, kemudian menentukan variabel menjadi himpunan fuzzy, menentukan derajat keanggotaan, menentukan fire-strenght, dan penegasan. Penggunaan metode ini diharapkan dapat memberikan solusi untuk mengatasi ketidakpastian dan jumlah produksi yang bersifat fleksibel. Pengembangan aplikasi ini menggunakan software Macromedia Dreamweaver, Adobe Photoshop, bahasa pemrograman PHP dan basis data MySQL. Sistem ini digunakan sebagai bahan pertimbangan bagi pemilik perusahaan dalam melakukan perencanaan jumlah produksi pada waktu yang akan datang. .
