Abstract

Child violence in educational settings is often rooted in mimetic desire, which provokes rivalry and emotional tension among students. This study investigates the dynamics of mimetic desire, rivalry, violence, and reconciliation as portrayed in Rasa, a novel by Tere Liye. Employing a descriptive qualitative approach with thematic analysis, the research applies René Girard’s theory of mimetic desire, focusing on the interconnected concepts of desire, rivalry, and reconciliation. Textual elements such as dialogue, narrative perspective, and character development are systematically examined through six analytical stages: data familiarization, coding, theme development, thematic review and coherence checking, theme definition and naming, and interpretive narrative construction. To ensure the reliability and validity of the findings, the study incorporates intra-coder consistency testing—by re-coding at different times—and peer debriefing for collaborative validation. The results reveal that Lin’s mimetic desire to emulate Jo’s academic success and social interactions with Nando leads to escalating rivalry, ultimately manifesting in conflict and interpersonal violence. This unmanaged mimetic rivalry results in emotional manipulation, symbolic violence, and social exclusion, reflecting real-world school dynamics. Significantly, Rasa also offers a narrative resolution through self-reflection and reconciliation, positioning literature not only as a mirror of school-based violence but also as a pedagogical tool. This study contributes to Indonesian literary scholarship by integrating mimetic theory into the analysis of contemporary fiction and enriches educational discourse through an empathy-driven approach to character education and conflict prevention.

Abstract

The increasing demand for crude oil or fossil fuel as a raw material for oil fuel has been steadily rising over time in line with the development that is taking place in Indonesia. However, biofuels are potential vegetable fuels that can be developed as alternative energy because they are renewable and can be renewed to overcome the energy crisis in the future. For this purpose, a double metal catalyst (impregnated with nickel and lanthanum), is used to make biofuels from sunflower seed oil. The effect of metal ratio on the yield of biofuel products is the concern in this study. The temperature of hydrocracking process was 250-330 ℃ with ratio of metal 5% and 10% (metal ratio 1:1 and 1:2). X-ray diffraction (XRD) shows that natural zeolite has a clinoptilolite phase, X-Ray Fluorescence (XRF) shows that acid and base activation increases the Si/Al ratio from 4.5 to 5, Scanning Electron Microscope – Energy Dispersive X-Ray (SEM-EDX) shows images of natural zeolite surfaces in the form of aggregate pieces, and Brunauer Emmett Teller (BET) shows that acid and base activation increases SBET from 29.96 to 49.73 m2/g and forms a hierarchical natural zeolite. The impregnation of Ni-La/Zeolite catalyst has been successfully carried out using the incipient wetness impregnation method and the best catalyst results were obtained, namely Ni-La/Zeolite 10% (1:2) with a surface area of 15.33 m2/gS. The addition of Nickel and Lanthanum metals caused a decrease in the surface area and average pore diameter of the zeolite. The lowest surface area and average pore diameter were found in the variation of the Ni-La/Zeolite 10% (1:2) catalyst, namely 15.33 m2/g and 13.99 nm. The highest hydrocarbon yield was found in the hydrocracking process with the Ni-La/Zeolite 10% (1:1) catalyst with gasoline, kerosene and gasoil fractions of 0.91; 0.39 and 8.32 (%wt), respectively. The hydrocarbon compound composition of the catalyst includes n-paraffin 4.43%, isoparaffin 0.21%, cycloparaffin 2.99% and olefin 2.71%.

Abstract

This research examines the development of Pentigraf, an Indonesian minifiction form with a three-paragraph structure initiated by Tengsoe Tjahjono to suit modern, fast-paced culture. The emergence of Pentigraf and its community, i.e., KPI (Kampung Pentigraf Indonesian or the Indonesian Pentigraf Village), influenced the dynamics of the Indonesian field of cultural production. Using Bourdieu’s theory, it analyses Pentigraf’s position in cultural production from 2016-2023 based on literature reviews, media content analysis, competition records, and participatory observations in KPI. By studying the legitimacy and consecration of Pentigraf in the cultural production field, the research provides insights into how this literary format has been embraced by various institutions, serving as a medium for amateur writers. This research shows that Pen-tigraf has gained institutional support within the cultural production and has adapted to the literary environment by integrating conventional and digital to promote a new literary work. The position of Pentigraf moves from the left to the right below in Bourdieu’s diagram of cultural production, indicating its movement toward popular literature. The conclusion underscores the usefulness of Bourdieu’s framework in understanding new literary phenomena and highlights the implications of Pentigraf for the growth of popular literature in Indonesia.

Abstract

Hydrotalcite (HT) is a type of clay mineral belonging to the group of layered double hydroxides (LDHs) or anionic clays, which has a layered structure like brucite (Mg(OH)₂), but some of the divalent cations (such as Mg²⁺) are replaced by trivalent cations (such as Al³⁺). HT as a heterogeneous catalyst is particularly attractive because it is easy to separate and resistant to high temperatures. HT as a catalyst can be used in hydrocracking reaction to produce biofuel. Metal impregnation on HT is very promising to enhance catalytic activity especially with the bifunctional mechanism of catalyst. Ni-V metal impregnation has been successfully carried out on HTc using wet impregnation method which is indicated by the results of X-Ray Diffraction (XRD) which shows the emergence of typical peaks of both metals and HTc in 2θ = 35‒70⁰ for HTc, 2θ = 37.22⁰ (NiO) and 37.35⁰ (V2O5) regions, 2θ = 43.58⁰ for NiO, 2θ = 61.26⁰ (V) and 63.07⁰ (Ini). Scanning Electron Microscopy-Energy Dispersive X-ray (SEM-EDX) show a shape that is consistent with the characteristics of HT, namely the shape of the particles layered overlapping each other. In addition, the particle size of HTc is quite small with a scale of 1 μm indicating a particle size of hundreds of nanometers. EDX mapping shows that Ni and V have been dispersed evenly on the HTc surface. Based on the results of N2 adsorption-desorption isotherms, it shows that mesopores are formed which are characterized by hysteresis loops. Ni-V metal impregnation increases the surface area up to 19.915 m2/g and the pore diameter up to 37,642 nm. The results of the Waste Cooking Oil (WCO) hydrocraking reaction show that Ni-V metal impregnation can reduce the carboxylic acid composition up to 67.81% and increase hydrocarbons up to 15% at 10% Ni-V/HTc 1:2.

Abstract

This study examines four Indonesian women’s travel narratives published between 2011 and 2014: The Naked Traveler One Year Round The World Trip (Trinity), The Jilbab Traveler (Asma Nadia), Perempuan Merah Putih (Nungky Irma Nurmala Pratikno), and London: Angel (Windry Ramadhina) through the concept of ambivalent agency by Ullah (2025) and Spivak’s (1994) notion of the double bind. This study reinterprets these contradictions not as conscious political strategies, but as symptoms of a complex, often complicit, negotiation with hegemonic power. The analysis reveals that agency in these texts is achieved through patterned accommodations to the very structures they critique: Trinity articulates agency through self-orientalizing mimicry that internalizes the tourist gaze; Nadia navigates the commodification of piety, transforming the jilbab into a neoliberal lifestyle brand; Nungky operates within the gendered constraints of State Ibuism, performing empowerment only within state-sanctioned nationalism; and Ramadhina utilizes intimate relationality to manage the anxiety of the unhomely. The study concludes that Indonesian women’s travel writing is less a site of pure resistance than a space of ambivalence, where the postcolonial subject must inhabit conflicting norms, simultaneously resisting and reproducing patriarchal and capitalist logics to achieve mobility.

Abstract

Pancasila faces complex character crises in the digital era, demanding holistic character education. This qualitative study formulates a comprehensive strategy to strengthen Pancasila values through the theological and pedagogical principles of Islamic Religious Education (IRE) within the Kurikulum Merdeka. Using a narrative literature review of 15 selected journals, the study reveals that IRE functions as the theological-ethical soul of Pancasila. The novelty of this research lies in formulating a practical synergy: integrating religious moderation (wasathiyah) and multicultural strategies into the Pancasila Student Profile (P5). This integration effectively counters radicalism and fosters social solidarity (ukhuwah basyariyah). The study concludes that IRE transcends ritualistic doctrine, acting as a primary catalyst for national character. It successfully bridges individual piety with inclusive civic action, forming a spiritually deep and highly loyal younger generation.

Abstract

Cold War literary studies remain dominated by Western perspectives, particularly narratives from the United States and the Soviet Union, resulting in the marginalization of literary experiences and criticism from Third World countries. Indonesian literary works that represent America as an object of critique have seldom been read as integral to global Cold War literary discourse. This research aims to uncover and explain criticisms of the United States in Umar Kayam's short story collection Seribu Kunang-Kunang di Manhattan within the context of Cold War Literature, using Indonesia’s perspective as part of the Third World. This study employs a qualitative-descriptive approach within a postcolonial framework, combining the concept of Occidentalism with an intersectional analysis of race, class, and gender. The analytical method used is a wide, close, and deep reading approach that integrates textual analysis and historical documents. The research data include primary textual units from short stories, as well as secondary data, including historical, and relevant academic literature. The results show that Kayam delivers an ideological critique of America by portraying it as a dark and ambiguous space, with a working-class society that is vulnerable and apolitical, and patriarchal gender relations, thereby dismantling the myth of America as a symbol of progress and universal freedom. This research concludes that Indonesian literature serves as a legitimate medium for cultural and ideological critique of Western hegemony, while also affirming Indonesia’s active position in global Cold War literary discourse.

Abstract

Indonesia’s limited fossil fuel reserves, coupled with increasing national energy demand, highlight the need for alternative and renewable fuel sources. Biomass-derived bio-oil produced through pyrolysis represents a promising solution that can both reduce dependence on petroleum-based fuels and mitigate environmental pollution from underutilized biomass waste. This study investigates the production of bio-oil from candlenut shells and coffee shells through pyrolysis at varying temperatures (250, 350, and 450°C), conducted with and without a NiCl2 catalyst. The bio-oil was characterized for yield, density, and viscosity. The highest bio-oil yields from non-catalytic pyrolysis were achieved at 450°C, amounting to 39.14% for candlenut shells and 41.80% for coffee shells. Catalytic pyrolysis using NiCl2 enhanced the bio-oil yield, producing up to 55.78% (candlenut shells at 450°C) and 58.05% (coffee shells at 350°C). Density measurements showed the highest values in catalytic pyrolysis at 250°C, while the lowest densities were observed in non-catalytic pyrolysis at 450°C. Viscosity followed a similar trend, decreasing with increasing temperature and the presence of the catalyst. FTIR analysis confirmed the presence of functional groups including C–O, C=O, C=C, C≡C, C–H, and O–H. Overall, this study demonstrates the potential of candlenut and coffee shell waste as feasible feedstocks for bio-oil production, offering alternative renewable energy sources for future applications.
