<p align="justify">Oyster mushroom (Pleurotus ostreatus) is one of the many wooden mushrooms cultivated in Indonesia. The use of traditional technology make oyster mushroom production in Indonesia fluctuated. According to the Central Statistics Agency, demand for oyster mushrooms in Indonesia continues to increase until 2017 reached the figure of 0.177 kg / capita / year. Engineering of mushroom cultivation process is needed to increase the production number. One of the efforts made is to approach the chemical aspects through the use of vitamins and growth regulators. The techniques carried out in this study were the addition of vitamin B1 as well as hormone auksin and giberelin on planting medium. This research used factorial completely randomized design (RAL) with 8 variation of treatment (vit B1-0,3ppm; vit B1-0,6ppm; auksin 20ppm; giberelin 20ppm; vitamine combination B1-0,3ppm + auksin 20ppm; vit B1-0, 3ppm + giberelin20ppm; vit B1-0,6ppm + auksin 20ppm and vit B1-0,6ppm + giberelin 20ppm) with 6 repetitions each. Data were analyzed by ANOVA statistical test and Duncan's advanced test. The results of a 2-month observational study showed that the fastest and most markedly different time of formation of primordia (4 days) occurred in the treatment of H2V0 (gibberellin without vitamins). The highest diameter of the hood and significantly different from other treatments and controls was achieved in H1V0 treatment (auksin without vitamins), H2V0 (gibberellin without vitamins), H0V2 (vitamin B1-0.3ppm without hormone) with a diameter of 10.4; 9.9; 7.6 cm in a row. The highest number of fruit bodies (6 hoods) occurred in the H2V2 treatment (giberelin combination of vitamin B1-0.3 ppm) but did not differ significantly. The highest wet weight of the 2-month harvest period (111.44 g / log) was achieved in H2V2 treatment (gibberellin combination vitamins B1-0.3 ppm) which also did not differ significantly. The highest dry weight of the 2 month harvest period (9.69 g / log) was achieved in H1V0 treatment (auksin without vitamins) which also did not differ significantly. From the results of this study can be concluded that the provision of vitamins and growth hormone regulator does not significantly affect the harvest quantity results but has a significant effect on the appearance and size of fruit body diameter.<p align="justify">
