description: Porang tuber (Amorphophallus oncophyllus) contains a potential compound in the form  of  glucomannan  which  can  be  extracted  physically,  chemically,  and mechanically.  Extraction  in  this  study  was  carried  out  mechanically  with  a  disc mill  and  blower.  The aims of  this  study  were to  determine  the  effect  of  porang flour particle size on yield, glucomannan content, and calcium oxalate content of glucomannan  flour,  to  determine  the  effect  of  blower  air  speed  on  yield, glucomannan  content,  and  calcium  oxalate  content  of  glucomannan  flour,  and  to determine the interaction of porang flour particle size. and the speed of blower air for  the  best  yield,  glucomannan  content,  and  calcium  oxalate  content  of glucomannan  flour.  The  study  was  arranged  factorially  in  a  Complete Randomized  Block  Design  (RAKL)  with  3  repetitions.  The  first  factor  in  the treatment  was  particle  size  (mesh)  consisting  of  3  levels,  namely  M1  (40  mesh); M2  (60  mesh);  and  M3  (80  mesh);  and  the  second  factor  in  the  treatment  was blower  air  speed  (m/s)  consisting  of  3  levels,  namely  K1  (5  m/s);  K2 (7.5 m/s); K3  (10 m/s).  This  research  consisted  of  mechanical  glucomannan  extraction process with disc mill and blower, testing crude glucomannan yield, glucomannan content, calcium oxalate content to get the best treatment, which were then tested physically and chemically. The data obtained were analyzed statistically using the Bartlett and Tuckey tests and then continued with the ANOVA test and LSD test at  the  5%  level.  The  results  showed  that  the  best  treatment  interaction,  namely M3K3 with a particle size of 80 mesh and a blower air speed of 10 m/s with the test  results  being  yield  52.90%,  glucomannan  content  94.45%,  calcium  oxalate content  0.06%,  moisture  content  9.64%,  ash  content  2.80%,  protein  content 0.88%,  Loss  on  Drying  6.2%  ,  water  holding  capacity  595.66%,  viscosity  48000 cP, chloride content 0.02%, lead content 0.21%, starch content 0.95%, crude fiber 1.44%, pH 6.9, solubility in alcohol 0 .17%, and solubility in ether 0.22%.Keywords: glucomannan, disc mill, blower, mesh, calcium oxalate    Umbi  porang (Amorphophallus  oncophyllus) mengandung  senyawa  potensial berupa  glukomanan  yang  dapat  diekstraksi secara  fisik,  kimia,  dan  mekanis. Ekstraksi  pada  penelitian  ini  dilakukan  secara  mekanis  dengan disc  mill dan hembusan blower. Tujuan dari  penelitian  ini  adalah  untuk  mengetahui  pengaruh ukuran  partikel  tepung  porang  terhadap  rendemen,  kadar  glukomanan,  dan  kadar kalsium  oksalat  tepung  glukomanan,  mengetahui  pengaruh  kecepatan  udara blower terhadap rendemen, kadar glukomanan, dan kadar kalsium oksalat tepung glukomanan,  dan  mengetahui  interaksi  ukuran  partikel  tepung  porang  dan kecepatan  udara blower terhadap  rendemen,  kadar  glukomanan,  dan  kadar kalsium  oksalat  tepung  glukomanan  terbaik. Penelitian  disusun  secara  faktorial dalam  Rancangan  Acak  Kelompok  Lengkap  (RAKL)  dengan 3 ulangan. Faktor pertama  pada  perlakuan  adalah  ukuran  partikel  terdiri  atas  3 taraf  yaitu  M1  (40 mesh);  M2  (60  mesh);  dan  M3  (80  mesh);  serta  faktor  kedua  pada  perlakuan adalah kecepatan udara blower terdiri atas 3 taraf yaitu K1 (5 m/s); K2 (7,5 m/s); K3  (10  m/s).  Penelitian  ini  terdiri  atas  proses  ekstraksi  glukomanan  secara mekanis dengan disc mill dan hembusan blower, pengujian rendemen glukomanan kasar,  kadar  glukomanan,  kadar  kalsium  oksalat  untuk  mendapatkan  perlakuan terbaik, kemudian diuji secara fisik dan kimia. Data yang dianalisis secara statistik menggunakan  uji  Bartlett  dan  Tuckey  dilanjutkan  dengan  uji  ANOVA  dan  uji BNT  pada  taraf  5%.  Hasil  penelitian  menunjukkan interaksi  perlakuan  terbaik yaitu M3K3 dengan ukuran partikel 80 mesh dan kecepatan udara blower sebesar 10  m/s dengan  hasil  pengujian rendemen  sebesar 52,90%,  kadar  glukomanan 94,45%,  kadar  kalsium  oksalat  0,06%,  kadar  air  9,64%,  kadar  abu  2,80%,  kadar protein 0,88%, Loss on Drying 6,2%, daya ikat air 595,66%, viskositas 48000 cP, kadar  klorida  0,02%,  kadar  timbal  0,21%,  kadar  pati  0,95%,  serat  kasar  1,44%, pH 6,9, kelarutan dalam alkohol 0,17%, dan kelarutan dalam eter 0,22%.
