Abstract

The purpose of this study is to determine whether supervision and division of labor affect employee morale at Pia Hotel Pandan, Central Tapanuli Regency. This study is a descriptive quantitative approach using a saturated sample of 61 people. Data were analyzed using multiple linear regression analysis. The findings of the study indicate that supervision and division of labor can affect employee morale by 55.5%, while the remaining 44.5% can be influenced by other factors not discussed in this study. Supervision and division of labor together have a positive and significant effect on work enthusiasm, where F count (38.365) is greater than F table (3.16). Supervision has a significant effect on work enthusiasm, where the t-count value of 3.072 is greater than the t-table value of 2.001 (3.072 > 2.001) or significant (Sig-t) of 0.003 < α (0.05). Division of labor has the most dominant effect on work enthusiasm, where the t-count value of 5.045 is greater than the t-table value of 2.001 (5.045 > 2.001) or significant (Sig-t) of 0.008 < α (0.05). The multiple linear regression model obtained by the regression equation is Y = Y = 4.408 + 0.321X1 + 0.555X2 indicating a positive direction.

Abstract

Project scheduling is a method to measure the duration required by an activity to be completed, scheduling in construction projects is also used to determine the start and finish times of each activity in the project. The Precedence Diagram Method (PDM) is a network with the Activity on Node (AON) model, usually depicted as of a square with arrows that connect between activities that are the link between project activities. Through the results of the analysis in this study, it was found that the duration of the Simpang Islamic Center – Tanjung Selatan Road Construction project, Tabalong Regency, was 214 working days or 259 calendar days and the total normal duration reached 300 calendar days, starting on January 6, 2022 and ending on September 22, 2022.

Abstract

Although environmental noise has been extensively studied, limited research has compared the differential effects of natural and urban soundscapes on psychological outcomes. This pilot study examined the impact of urban and natural soundscapes on students’ concentration and affective responses. A pre–post experimental design with two groups was implemented, involving 12 undergraduate participants (aged 18–24 years) with equal gender representation. Concentration was measured using the polyshape board, which was preliminary validated in this study, while affective states (pleasantness and arousal) were assessed using the Affect Grid Scale (AGS) before and after exposure. Given the limited sample size and the ordinal data, the Wilcoxon Signed-Rank test was applied. The analysis revealed a significant difference in concentration between the two conditions (p=0.037), with higher and more stable scores observed under natural sound exposure (M=32.9; Md=35.5) compared to urban sound conditions (M=31.1; Md=34.5). Manipulation checks indicated no significant difference in pleasantness (p=0.224), while arousal differed significanly between conditions (p=0.045), with higher arousal reported in the urban sound conditions. These findings suggest that natural sounds may be associated with improved concentration and reduced arousal in controlled educational and laboratory settings. However, given the small sample size and short exposure duration, the findings should be considered preliminary and require further investigation with higher and more diverse samples.
