Abstract

From past to present, masculinity has continuously shaped how men are expected to behave in society, especially in adolescence. The television series Adolescence highlights these expectations by portraying different male characters in their daily interactions, reflecting how masculinity operates in real life. This study aims to explore the types of masculinity displayed in the series based on R.W. Connell’s theory (2005), which classifies masculinity into hegemonic, complicit, subordinate, and marginalized types. The research applies a qualitative descriptive method to examine social realities through selected dialogues and scenes. The findings reveal that hegemonic masculinity (64%) is the most frequently represented form, where dominance, toughness, and emotional restraint are highlighted as masculine ideals. Subordinate masculinity (27%) follows, showing that expressions such as emotional openness or queerness are still viewed as less masculine. Marginalized masculinity (9%) appears in contexts involving race and class, while complicit masculinity (5%) is rarely shown, suggesting that most characters either fully embody or struggle against dominant norms. The data shows how the media continues to uphold hegemonic masculinity while only subtly acknowledging its alternatives, offering insight into the gender dynamics experienced by teenage boys today.

Abstract

Shrimp shell waste is a potential marine biomass resource rich in bioactive compounds such as astaxanthin and chitin, yet remains underutilized in the livestock sector. This study aimed to evaluate the effect of incorporating shrimp shell meal into duck (Anas sp.) feed rations on the yolk color intensity of duck eggs. The experimental design applied a completely randomized design (CRD) with a single factor and four treatments: D0 (100% rice bran, control), A1 (rice bran + 2% shrimp shell meal), A2 (rice bran + 6%), and A3 (rice bran + 10%), with a 21-day observation period. The primary parameter measured was yolk color intensity, assessed visually using a standardized color scale. The results indicated that the addition of shrimp shell meal significantly enhanced yolk color intensity, with the highest pigmentation observed in the A3 treatment. Astaxanthin, functioning as a natural carotenoid pigment, was biologically absorbed and distributed into the yolk via lipophilic pathways, while chitin supported gut health and nutrient absorption efficiency. This study aligns with the principles of the circular economy by valorizing marine processing waste as a functional feed ingredient. A 10% inclusion rate was found to be visually optimal; however, further studies are required to assess its physiological impacts and economic feasibility in broader production contexts.

Abstract

Shrimp shell waste is a chitin-rich biopolymer with high potential for microbial bioconversion into value-added products. This study aimed to analyze the microstructural degradation of shrimp shells by the actinomycete isolate 18D38A1 under solid-state fermentation, using Scanning Electron Microscopy (SEM). A fresh sample preparation method was applied, involving washing and immersion in 70% ethanol, followed by vacuum drying and gold sputter-coating. Fermentation was conducted over a period of 1 to 4 days. SEM analysis revealed progressive structural deterioration of the shrimp shell matrix, including increased surface erosion, pore formation, and breakdown of chitin fibers, which became more pronounced each day. These observations indicate active and time-dependent biodegradation by isolate 18D38A1. The sample preparation protocol proved effective in preserving morphological features and enhancing SEM image clarity, enabling precise visualization of degradation stages. The combination of solid-state fermentation and optimized SEM preparation provides a reliable approach to evaluate the biodegradation process of chitinous waste by actinomycetes over time. This study demonstrates a practical SEM sample preparation method for visualizing the progressive biodegradation of shrimp shell by actinomycete isolate 18D38A1 from day 1 to day 4.
