Abstract

CV Agrindo Suprafood as one of the largest suppliers of nata de coco in Yogyakarta is only able to meet 40% of market demand due to the limitations of coconut water. An alternative strategy to tackle this problem is by looking for coconut water substitute as raw material for the production of nata. The purpose of this study was to analyze the potential of cassava and glucose syrup as raw material alternative of nata and its feasibility on an industrial scale . Formulation of nata is performed on a pilot plant scale with cassava and glucose syrup as raw material. Cassava glucose and glucose syrup were separately used as a growth medium of Acetobacter xylinum for the production of nata. The physical, chemical, and sensory evaluation as well as technical and financial feasibility analysis were conducted on the nata product. The best formula for production of nata de cassava and nata de glucose was obtained by a combination of glucose, glucose syrup, coconut water, ZA,vinegar, and acetic acid. Based on the analysis, it was concluded that both of nata production were industrially-feasible in terms of both technical and financial analysis. However, based on the financial analysis, nata de glucose was more prospective than nata de cassava.

Abstract

Industri Maju Mulyo merupakan salah satu industri logam berbahan alumunium masih eksis di Kelurahan Tegalrejo Magelang. Keberadaan industri logam berbahan alumunium di Kelurahan Tegalrejo Magelang memberikan potensi yang besar terutama di bidang ekonomi, sosial, pendidikan dan lapangan kerja. Industri perabot rumah tangga berbahan alumunium juga memberikan dukungan pada wisata alam dan agro di daerah lereng gunung Merapi dan Merbabu khususnya wisata alam pegunungan Kopeng dan Ketep. Tantangan produk dengan desain rumit dan ukuran relative besar masih menjadi kendala. Proses pengerjaan produk dengan profil lekukan skala kecil melibatkan beberapa proses meliputi pemanasan awal, penekuk bahan dan pengelasan. Sedangkan proses pengerjaan produk dengan profil lekukan dan ukuran besar secara umum dikerjakan melalui beberapa tahap meliputi pengerolan, pembentukan, pengelasan dan penyelesaian akhir.  Industri Maju Mulyo merupakan industri yang mulai berbenah dan berkembang menuju industri dengan menejemen yang baik dan bersaing secara kompetitif.  Dan tujuan kegiatan penerapan teknologi melalui Program Kemitraan Masyarakat meliputi pelatihan dan konsultasi perancangan dan pengerjaan produk perabot rumah tangga berbahan alumunium, pendalaman, pengoperasian dan perawatan mesin potong plat otomatis. Pemotongan plat secara manual konvensional dilakukan dengan teknik pengoresan dan gunting plat. Aplikasi pemotong plat dengan bersumber energi listrik dilakukan dengan mengaplikasikan gaya geser pada salah satu pahat potong yang bergerak arah bolak-balik (maju-mundur) di mana salah satu pahat potong dia
