Literature is not only a source of entertainment, but also a tool for contemplating human life that is full of internal conflicts and psychological issues. Short stories as a type of literature often present the realities of life in a concise yet meaningful way, making them interesting to analyze with a variety of scientific methods. This research focuses on the short story "Happiness That Kills" by applying two main approaches, namely the analysis of intrinsic elements and literary psychology. This story depicts a happy state that appears from the outside, but actually hides the emotional burden experienced by the main character, Malla. The method applied in this study is qualitative descriptive with literature study techniques, which is oriented towards the introduction of themes, plots, characters, settings, and mandates, as well as exploring the psychological dynamics of characters using Freud's psychoanalytic theory. The results of the study show that the internal conflicts in this story arise from the battle between the id, ego, and superego, especially when Malla struggles to maintain harmony in her family at the expense of herself. Overall, this short story shows that forced happiness can lead to suffering. By combining structural and psychological analysis, this study reveals the deep meaning related to social pressures, inner struggles, and humanitarian messages that the author seeks to convey. It is hoped that the results of this research can contribute to the study of literature, especially in understanding the relationship between story structure and the psychological condition of characters in contemporary literary works.

The increasing consumption of packaged food products in Indonesia reflects modern lifestyle changes but simultaneously raises public health concerns related to high calorie, sugar, and fat intake. Nutritional information presented on food labels consists of multiple interrelated variables, making it difficult to identify dominant nutritional factors that characterize packaged food products. This study aims to apply Principal Component Analysis (PCA) to reduce the dimensionality of nutritional data and to map the nutritional characteristics of packaged food products in Indonesia. The research employs a quantitative exploratory approach using secondary data obtained from nutrition facts labels of 1,651 packaged food products. Seven nutritional variables were initially analyzed, namely total energy, protein, total fat, total carbohydrates, sugar, sodium, and dietary fiber. Data preprocessing included data cleaning, Z-score standardization, and iterative variable selection based on the Kaiser-Meyer-Olkin (KMO) measure and Bartlett’s Test of Sphericity to ensure sampling adequacy and sufficient correlation among variables. Variables with low sampling adequacy and perfect multicollinearity were eliminated, resulting in five variables retained for the final PCA model. Principal components were extracted using the eigenvalue greater than one criterion and confirmed through a scree plot, followed by Varimax rotation to enhance interpretability. The results indicate the formation of two principal components explaining approximately 69.7% of the total variance. The first component represents energy density and macronutrient richness, while the second component reflects carbohydrate-related characteristics, particularly the contrasting pattern between sugar and dietary fiber. Biplot visualization further illustrates product distribution based on these components. The findings demonstrate that PCA effectively simplifies complex nutritional information and provides a clear nutritional mapping of packaged food products, offering practical insights for consumers, producers, and policymakers in supporting healthier food choices in Indonesia.

Film as a cultural text never exists independently but is always connected to previous texts that form a network of meanings. The phenomenon of film remakes demonstrates a strong intertextual relationship, as seen in My Annoying Brother in its South Korean and Indonesian versions. This study examines the intertextual relationship between the two films and analyzes the ways the story is reworked within different social and cultural contexts. The purpose of this research is to investigate the intertextual relations between the South Korean version as the source text and the Indonesian version as the transformed text by applying the concepts of opposition, transposition, and transformation. This study employs a qualitative descriptive approach using an observation method through careful and repeated film viewing, accompanied by note-taking of important dialogues and significant scenes. The research data consist of narrative elements of the films, including plot, characters, conflict, setting, and cultural values. The findings reveal that although both films share similar narrative structures and central conflicts, the Indonesian version incorporates local cultural adaptations that generate new meanings within the context of cross-cultural film remakes.

Teaching fiction in Indonesian language classrooms is often constrained by text-centered instruction and limited use of engaging digital media. In the era of Generation Z learners who are visually and digitally oriented, innovative learning materials are needed to enhance motivation, interpretation, and comprehension of literary texts. This study aims to develop and evaluate a Scribus-based digital magazine for fiction learning by integrating the ADDIE model within a qualitative descriptive framework. The research adopted a qualitative descriptive design comprising five stages of the ADDIE model: Analysis, Design, Development, Implementation, and Evaluation. The study was conducted at SMP Negeri 10 Semarang, involving one Indonesian language teacher and fifteen Grade VIII students, who were selected through purposive sampling. Data were collected through observation, interviews, and documentation, and analyzed using the Miles and Huberman model (data reduction, data display, conclusion drawing). Media and content experts conducted validation to assess the feasibility, usability, and pedagogical quality of the content. Findings revealed that the Scribus-based learning media effectively increased students’ engagement and comprehension in analyzing fictional elements such as plot, character, and setting. Expert validation results indicated a high feasibility level, with mean scores above 85% in design and content quality. Teachers reported improved classroom interaction and creativity, while students expressed enthusiasm for the visual and interactive format. The study concludes that open-source tools, such as Scribus, can provide cost-effective and pedagogically sound alternatives for developing literary learning media. The integration of ADDIE and multimodal design promotes contextual, engaging, and sustainable learning experiences. Future research should explore multimedia enhancements, such as audio storytelling and cross-curricular applications, to broaden the pedagogical impact.

Continuous chemical control of rat pests (Rattus spp.) can sometimes lead to resistance and resurgence problems, and even some cases of inaccurate targeting ultimately killing livestock. The idea of ​​​​repelling rats in rice fields using vibrations of crickets and other natural animals transmitted via radio has been done and the results are quite optimal for rat control, but it has not been done in corn cultivation. The purpose of this study was to determine the effect of cat sound audio on the intensity of rat pest attacks (Rattus spp.) in corn (Zea mays L.) plantations. The research location was in a farmer's land owned by a farmer in Dagan Village, Solokuro District, Lamongan Regency. Determination of sampling points using the diagonal method, each into 5 sub-observation plots. In each sub-plot, markers were placed as sampling points. Audio with cat and bird sounds was played continuously from 05.00 pm - 07.00 am. Observations were conducted at 7:00 a.m. at all sampling points at 30 and 60 days after planting. Observations were conducted for three days using audio and three days without audio. Damage symptoms were observed directly at each sampling point. Corn plants showing symptoms were then recorded and analyzed using the Damage Intensity formula. Observations showed that the use of cat sound audio was able to reduce the level of rat infestation. At 30 days after planting, the damage percentage was reduced by 8.33%. Meanwhile, at 60 days after planting, the damage percentage was reduced by 18.33%.

Oral literature is a form of storytelling from one individual to another in a concise manner as a representation of a society's culture. One type that is interesting to study in this field is legends. This study examines the Keong Mas legend using Burhan Nurgiyantoro's structuralism approach theory, which focuses on analyzing the relationship between intrinsic and extrinsic elements in literary works. This study uses a qualitative descriptive method that aims to reveal the narrative structure and social and cultural meanings contained in the legend as a reflection of the moral values and local wisdom of the people of East Java. The information collection method used observation and note-taking. The results of the analysis show that the Keong Mas legend has a cohesive story structure, including theme, characters, plot, setting, and point of view, which simultaneously reflect the values of loyalty, justice, and family conflict in a socio-cultural context. These findings confirm the relevance of oral literature as a medium for the inheritance of living and evolving cultural values, and contribute to the understanding of cultural identity and literary aesthetics in Indonesia, especially in the East Java region.
