        abstract = {The use of synthetic fertilizer affects on soil fertility, such as the structure of soil 
is  becoming  hard,  there  is  no  biological  activity  in  soil,  and  the  harmony  of 
nutrient elements in soil is distracted. Therefore, to repair the  condition of soil, it 
needs  to  use  rice  husk-biochar  and  trychocompos  in  a  balance  number.  The 
purpose of this study is to see the affect of rice husk-biochar and trychocompos 
due  to  growth  and  productivity  of  Pakcoy,  and  also  the  affect  of  using 
trychocompos  efficiently.  This  study  was  using  complete  randomised  factorial 
design. There are two factor, the first factor was biochar dose (0 g, 50 g, 100 g), 
and  another  factor  was trychocompose  dose  (0  g,  500  g,  1000  g,  1500  g),  each 
treatment  was  repeated  3  times.  Rice  husk  -  biochar  factor  was  significantly 
affected to evapotranspiration, plant height, number of leaf, wide of canopy, fresh 
gross  weight,  water  productivity,  and  fertilizer  productivity.  But  it  was  not 
significantly  affected  to  soil  solidity  and  soil  pH.  Trychocompos  factor  was 
significantly affected to soil solidity, plant height, number of leaf, green color of 
leaf,  wide  of  canopy,  fresh  gross  weight,  water  productivity,  and  fertilizer 
productivity.  But  it  was  not  significantly  affected  to  soil  pH  and 
evapotranspiration.  Adding  100g/pot  of  biochar  dose  could  decrease 
recommendation of trychocompos, that is 1500 g/pot to 1000 g/pot according to 
study which had been done.

Penggunaan pupuk kimia menimbulkan dampak negatif terhadap kesuburan tanah, 
struktur  tanah  (menjadi  keras),  mengurangi  aktifitas  biologis  dalam  tanah,  dan 
mengganggu keseimbangan unsur hara pada tanah. Untuk mengatasi hal tersebut 
aplikasi  biochar  sekam  padi  dan  pupuk  trichokompos  dalam  jumlah  berimbang 
perlu dilakukan untuk memperbaiki kondisi tanah. Penelitian ini bertujuan untuk 
melihat  pengaruh  penambahan  biochar  sekam  padi  dan  trichokompos  terhadap 
pertumbuhan  dan  produktivitas  tanaman  pakcoy.  Penelitian  disusun  dalam 
Rancangan Acak Lengkap (RAL) faktorial dengan dua faktor yaitu dosis  biochar
(A) dengan 3 taraf dosis yaitu 0 gram, 50 gram dan 100 gram per pot, dan dosis 
trichokompos (B) dengan 4 taraf yaitu 0 gram, 500 gram, 1000 gram, dan 1500 
gram per pot. Masing-masing perlakuan dilakukan 3 kali ulangan. Hasil penelitian 
menunjukkan  bahwa  faktor  biochar  sekam  padi  berpengaruh  nyata  pada 
evapotranspirasi,  tinggi  tanaman,  jumlah  daun,  luas  kanopi,  total  bobot  segar, 
produktivitas  air  dan  produktivitas  pupuk,  tetapi  tidak  berbeda  nyata  pada 
kepadatan tanah dan pH tanah. Sedangkan faktor trichokompos berpengaruh nyata 
pada  kepadatan  tanah,  tinggi  tanaman,  jumlah  daun,  warna  hijau  daun,  luas 
kanopi, total bobot segar, produktivitas air dan produktivitas pupuk, tetapi tidak 
berbeda  nyata  pada  pH  tanah  dan  evapotranspirasi.  Hasil  penelitian  juga 
menunjukkan  bahwa  penambahan  biochar  dengan  dosis  100  gram/pot  dapat 
meningkatkan  efektivitas  trichokompos  dan  mengurangi  dosis  trichokompos 
rekomendasi (1500 gram/pot) menjadi 1000 gram/pot.
