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

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 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.

Abstract

This study explores the duality of the main character’s persona in The Mask (1994) by applying Christopher Vogler’s narrative framework within the context of film studies. The research aims to investigate the concept of the anti-hero as a recurring character type in modern narrative texts, particularly in cinematic works, where characters are defined by flawed attributes and ethically ambiguous behavior. The relevance of the anti-hero lies in its deviation from conventional heroic archetypes and its function as a representation of shifting public values and beliefs. This study employs a descriptive qualitative method using a narrative structuralism approach. The analysis draws on Christopher Vogler’s concept of the anti-hero and Eaton’s (2012) anti-hero theory to examine narrative elements within the film. The film’s narrative presents the main character through traits such as manipulative, cruel, petty, malicious, selfish, ill-tempered, and duplicitous behavior. Primary data consist of significant character interactions, dialogues, and visual representations in specific scenes, while secondary data are obtained from previous studies and relevant literature on anti-hero representation and heroic film theory. The findings indicate that the main character in The Mask successfully embodies the anti-hero archetype by critiquing everyday identity repression, releasing subconscious impulses, and disrupting social conformity through chaos. This study contributes to academic discussions on anti-hero characters by demonstrating how The Mask, beyond its cartoonish entertainment value, functions as a structural narrative text in which manipulative traits dominate the character’s transformation.
