This research analyzes factors affecting the performance of the APIP (Government Internal Supervisory Apparatus) at the Inspectorate of Humbang Hasundutan Regency, using workplace stress as a moderating variable. The causal research analyzes and interprets numerical data to pinpoint the effect of independent variables on the dependent variables. Fifty-four members of the Government Internal Supervisory Apparatus (APIP) at the Inspectorate of Humbang Hasundutan Regency were selected as the samples. The findings indicate that competence (variable X1) positively and significantly affects APIP performance (variable Y). On the other hand, motivation (variable X2) has positive and significant effects on APIP performance (variable Y). Educational background (variable X3) positively and significantly affects APIP performance (variable Y). Also, independence (variable X4) positively and significantly affects APIP performance (variable Y). Simultaneously, workplace stress (variable Z) is the moderating variable that moderates the correlation of competence (variable X1), motivation (variable X2), educational background (variable X3), and independence (variable X4) with APIP performance (variable Z) at the Inspectorate of Humbang Hasundutan Regency.
