We present the photometric and spectroscopic studies of a Type Ib SN 2015apand a Type Ic SN 2016P. SN 2015ap is one of the bright (M$_{V}$ = $-$18.04 mag)Type Ib while SN 2016P lies at an average value among the Type Ic SNe (M$_{V}$= $-$17.53 mag). Bolometric light curve modelling of SNe 2015ap and 2016Pindicates that both the SNe are powered by $^{56}$Ni + magnetar model with$^{56}$Ni masses of 0.01 M$_{\odot}$ and 0.002 M$_{\odot}$, ejecta masses of3.75 M$_{\odot}$ and 4.66 M$_{\odot}$, spin period P$_{0}$ of 25.8 ms and 36.5ms and magnetic field B$_{p}$ of 28.39 $\times$ 10$^{14}$ Gauss and 35.3$\times$ 10$^{14}$ Gauss respectively. The early spectra of SN 2015ap showsprominent lines of He with a "W" feature due to Fe complexes while other linesof Mg II, Na I and Si II are present in both SNe 2015ap and 2016P. Nebularphase [O I] profile indicates an asymmetric profile in SN 2015ap. The [O I]/[CaII] ratio and nebular spectral modelling of SN 2015ap hints towards aprogenitor mass between 12 $-$ 20 M$_{\odot}$.
