Abstract

Rolling bearings are a common machine element found in rotary machines. The components in the rolling bearing such as the inner race, outer race, rolling element, and cage are the parts that are often damaged. Traditionally spectrum analysis is used to diagnose bearing defects. However, spectrum analysis is not effectively applied to bearings with early defects because the vibration signal generated is dominated by frequency components from other machine elements, so the frequency of bearing defects cannot be observed. This study proposes an alternative method of detecting bearing defects based on vibration signals using machine learning with a decision tree algorithm. This method is more effective than the spectrum analysis method because machine learning is based on feature extraction and pattern recognition of vibration signal data, therefore, providing classification results directly without further analysis. Vibration signals were recorded using an accelerometer mounted on a bearing housing on a test rig. Nine-time domain statistical parameters and six frequency domain statistical parameters were extracted from the vibration signal and then used as input for decision trees. The results show that the decision trees algorithm gives an accuracy of 94.4% for classifying three rolling bearing conditions using the input of 6 selected frequency domain statistical parameters.

Abstract

Demand for chicken consumption in Indonesia tends to increase every year. Broiler chickens were slaughtered at short age than past years, recently about 4 to 6 weeks. Total of 28 to 42 day old broiler chicks were distributed to completely randomized design in factorial scheme (4,5 and 6 weeks old) and 2 (male and female). All of evaluated were live body weight (LBW), carcass weight (CW), and carcass percentage (CP). Analyzed used Two Way analysis of variane (ANOVA) using SPSS with 5 replication. Duncan Multiple Range Test (DMRT) to determine the differences among treatment means.  The result showed that live body weight had unsignificantly effect of sex but affect (P<0.05) to slaughter age (4, 5 and 6 weeks) it was 1460 g, 1881 g and 2310 g. The means of carcass weight with different sex of male and female had unsignificantly effect it was 1.283 g and 1.223, so do the carcass percentage was 69.43 % and 70.15%. This research can be concluded that difference sexing un affect to body weight (1.891 g), carcass weight (1.253 g) and carcass percentage (69.79%), but the female broiler get higher than male broiler. Thus slaughter age affect (P<0.05) to body weight, carcass weight and carcass percentage, at 4 weeks old was tend to decrease but increasily at 5 weeks and 6 weeks old. The best body weight, carcass weight and carcaas percentage at 5 weeks old, according to market demand.

Abstract

In studies of diasporic literature, Salt Houses by Hala Alyan has frequently been examined through the lenses of trauma, displacement, and memory. However, less attention has been given to how silence operated as a mechanism through which these experiences were transmitted across generations. This study examined how inherited silence functioned not merely as the absence of speech, but as a force shaping memory, emotion, and diasporic identity. Tracing a Palestinian family across generations, the novel presented quietness and narrative gaps as embedded in both narrative form and everyday interaction. Drawing on Marianne Hirsch’s concept of postmemory and Stuart Hall’s theory of cultural identity, this study employed qualitative close reading of narrative gaps and silences within the text. The findings showed that the selective withholding of family history, emotional restraint, and epistemic gaps shaped the transmission of memory and the negotiation of diasporic identity across generations. More broadly, this study positioned silence as a communicative mode of transmission that extended existing discussions of postmemory and trauma beyond explicit narration and representation. By foregrounding silence as an active structure rather than a simple absence, this study contributed to broader discussions of intergenerational memory, diasporic belonging, and cultural identity formation. The study was limited to one literary text, which may have restricted broader generalizability.

Abstract

This article examines religious practices in contemporary performance through a sociological approach grounded in the Eastern cultural context of Indonesia. The study focuses on how monologue theatre Amir Nasution, Topeng Monyet (the monkey show) performances, theatrical livestreams of online commerce, and digital stages within WhatsApp groups function as social arenas where religious values are produced, negotiated, and reflected. Religious experience is not understood as fixed doctrine but as a social construction that is symbolic, theatrical, and performative. The sociology of religion provides the framework to interpret how rituals, symbols, and religious practices emerge within the everyday life of Indonesian society, which is shaped by collectivist values and the spiritual ethos of Eastern culture. The meaning of religiosity in performance is layered and dynamic, shaped by social interaction, local traditions, and symbolic actions that emphasize harmony and solidarity. WhatsApp groups, as digital spaces of interaction, are understood as spontaneous forms of metatheatre that embody dramatic structure, performative awareness, and fluid spiritual moments, reflecting religious practices in Eastern communities in the digital era. This article argues that theatre—whether conventional, digital, or metatheatrical—constitutes a social space relevant to contemporary life and offers religious experiences that resonate with the inclusive, collective, and tradition-rooted character of Indonesian Eastern culture.

Abstract

This study examines how sound design contributes to the construction of conflict and tension in World War Z (2013). Rather than functioning merely as an accompanying cinematic element, sound design serves as a narrative mechanism that shapes audience perception, emotional engagement, and spatial awareness throughout the film. This research employed a descriptive qualitative approach using textual film analysis. Twenty scenes were purposively selected based on the presence of dominant sound design elements including voice, music, sound effects, silence, and spatial sound and their direct contribution to the development of narrative conflict and tension. The analysis was conducted through thematic coding and interpreted using film sound theories proposed by Bordwell et al. (2019) and Petrie and Boggs (2018). The findings reveal four principal narrative functions of sound design. First, auditory cues trigger narrative disruption by prompting audiences to anticipate conflict before it becomes visually apparent. Second, dense and overlapping sound layers represent the collapse of social order while increasing emotional intensity and narrative immersion during outbreak sequences. Third, deliberate silence generates psychological tension by directing audience attention toward uncertainty and anticipation. Fourth, spatial sound constructs invisible threats through off-screen and directional audio, encouraging viewers to perceive danger beyond the visual frame and strengthening suspense. Collectively, these auditory strategies influence audience cognition, emotional responses, and engagement with the film's narrative progression. This study concludes that sound design in World War Z (2013) acts as a storytelling system that systematically constructs conflict, tension, and cinematic experience rather than functioning solely as a technical or aesthetic feature. The findings contribute to film studies by demonstrating the narrative significance of sound design and by integrating film sound theory with literary narrative analysis. In addition, the study offers practical insights for filmmakers, sound designers, and future researchers seeking to understand how auditory elements can enhance cinematic storytelling and audience immersion.

Abstract

This article examines the female body within a feminist framework that operates at the intersection of religion and social space through a reading of Dorothea Rosa Herliany’s poem Perempuan Berdosa. The poem portrays a woman burdened by accusations of sin and by the symbolic violence imposed upon her body by society. Images of being hunted, pressed down, and judged reveal how religious and social norms often position women as the source of moral wrongdoing. Feminist analysis challenges these patterns by asserting that women possess voices and lived experiences that cannot be reduced to moral stigma. Through this poetic reading, the article argues that the female body can become a site of resistance against patriarchal control and unjust moral scrutiny. Women’s awareness of their bodies and experiences opens possibilities for renegotiating identity, spirituality, and their place within everyday social life.
