PENGARUH MOTIVASI KERJA TERHADAP KINERJA KARYAWAN

The labor conditions in Indonesia are confronted with issues of unemployment, low productivity, and a significant number of workers employed in the informal sector. Low productivity impacts the level of employee performance. Performance becomes a crucial issue in the success of a company by requiring high-quality human resources. High-quality human resources will yield high performance. Enhancing performance requires motivation to create a greater sense of enthusiasm for task completion. The objective of this research is to determine the influence of work motivation on employee performance. This research employs a quantitative approach with data collected through accidental sampling technique involving 174 subjects. The analysis method used is multiple linear regression. The measurement tools used are IWPQ (Individual Work Performance Questionnaire) and MWMS (Multidimensional Work Motivation Scale), which consist of six dimensions: amotivation, extrinsic regulation social, extrinsic regulation material, introjected regulation, identified regulation, and intrinsic motivation. The overall results of this study through the six dimensions on the MWMS scale motivation does not have an influence on employee performance

Constraining {\it CP} violation in a softly broken A4A_4 symmetric Model

To understand the mass spectra of charged lepton and neutrino $A_4$ symmetry has been proposed in addition with the Standard $SU(2)_L\times U(1)_Y$ model. We break $A_4$ symmetry softly and the deviation from the tri-bimaximal mixing arises due to Zee mechanism. In the present work, we express two mixing angles $\theta_{13}$ and $\theta_{23}$ in terms of a single model parameter and experimental observables, such as, mixing angle $\theta_{12}$, mass squared differences $\Delta m^2_{21}$ and $\Delta m^2_{32}$. Using the experimental values of $\theta_{23}$, $\theta_{12}$, $\Delta m^2_{21}$ and $\Delta m^2_{32}$ we restrict the model parameter and we predict $\theta_{13}$. This model gives rise to $\theta_{13}\simeq 11^\circ$ if we allow $1\sigma$ deviation of $\theta_{23}$ and $2^\circ$ deviation of $\theta_{12}$ from their best fit values. Utilizing all those constraints, we explore the extent of CP violation parameter $J_{\rm CP}$ in the present model and found a value of $J_{\rm CP}\approx 2.65\times 10^{-3}$ (for $1\sigma$ deviation of $\theta_{23}$ and $2^\circ$ deviation of $\theta_{12}$) consistent with the other neutrino experimental results. We have studied the mass pattern of neutrino and neutrinoless double beta decay $(\beta\beta_{0\nu})$ parameter $|(M_\nu)_{ee}|$ in this model.Comment: 16 pages, 6 eps figures,revised materials and figures, version to appear in Phys.Rev.

Jet Identification with Zest

We present a new observable zest and demonstrate its potential to differentiate between jets originated by gluons, top quark and vector bosons. Zest has salient properties such as boost invariance, stability against global color flow of partons and inclusion or exclusion of a few soft particles to the jet. For a gluon jet, zest distribution is also insensitive to the jet mass. We show that when zest is used in conjunction with other observables, it can yield high gluon rejection while retaining high signal sample.Comment: 3 pages, 5 figures, XXII DAE-BRNS Symposium Proceeding

Generalized Z2×Z2\mathbb{Z}_2\times \mathbb{Z}_2 in Scaling neutrino Majorana mass matrix and baryogenesis via flavored leptogenesis

We investigate the consequences of a generalized $\mathbb{Z}_2\times\mathbb{Z}_2$ symmetry on a scaling neutrino Majorana mass matrix. It enables us to determine definite analytical relations between the mixing angles $\theta_{12}$ and $\theta_{13}$, maximal CP violation for the Dirac type and vanishing for the Majorana type. Beside the other testable predictions on the low energy neutrino parameters such as $\beta\beta_{0\nu}$ decay matrix element $|M_{ee}|$ and the light neutrino masses $m_{1,2,3}$, the model also has intriguing consequences from the perspective of leptogenesis. With the assumption that the required CP violation for leptogenesis is created by the decay of lightest ($N_1$) of the heavy Majorana neutrinos, only $\tau$-flavored leptogenesis scenario is found to be allowed in this model. For a normal (inverted) ordering of light neutrino masses, $\theta_{23}$ is found be less (greater) than its maximal value, for the final baryon asymmetry $Y_B$ to be in the observed range. Besides, an upper and a lower bound on the mass of $N_1$ have also been estimated. Effect of the heavier neutrinos $N_{2,3}$ on final $Y_B$ has been worked out subsequently. The predictions of this model will be tested in the experiments such as nEXO, LEGEND, GERDA-II, T2K, NO$\nu$A, DUNE etc.Comment: 37 pages, 12 figures, 9 tables, version accepted for publication in JHE
