Published: November 2023

This study aimed to evaluate the integration potential of cassava plants with goats in aerial production and goat manure-derived fertilizers. This research was conducted by purposive sampling with the consideration that Lampung Province is the central region of cassava production in Indonesia and is the region with the highest population of goats outside Java Island. Sampling was carried out in Central Lampung and East Lampung with high-production cassava and goats. Analysis using LQ, FPCI, carrying capacity, and fertilizer production from goat manure. The data obtained was then presented descriptively. The results showed that FPCI was located in Central Lampung, East Lampung, North Lampung, Tulang Bawang, and Tulang Bawang West. The highest aerial carrying capacity of cassava, 31.6%, was concentrated in Central Lampung, thereby affecting the livestock carrying capacity. LQ analysis obtained showed that around 66.7% of the area in Lampung was a goat livestock base. The highest production of fertilizer from goat manure was obtained by South Lampung, which covers around 24.5% of the total area of Lampung. The conclusion from this study was that areas that have potential for development supported by the provision of feed sourced from aerial sources from cassava plant waste if integrating cassava plants and goat livestock were East Lampung, Central Lampung, North Lampung, Tulang Bawang, and Tulang Bawang Barat districts.
Hitler's Car as Curriculum Text: Reading Adolescents Reading History
Authors: Matthews Sara
Published: November 2023

In this paper I explore how adolescents and beginning teachers encounter and respond to Hitler’s private limousine, a prominent and controversial exhibit at the Canadian War Museum. I first consider the conflicts of learning at stake when the curriculum contains representations of social trauma and war. I then draw from psychoanalytic perspectives on human development to think about what happens when conflict as it is represented in the world outside meets conflict in the individual’s inner world or psychology. Several research questions are raised: How do adults ‘read’ adolescents reading history and understand adolescents’ emotional connections to difficult historical objects? Further, how are these reading practices shaped by the traumatic losses that the concept of adolescence, as a category of the human, works to contain? What adolescence, as both a lived experience and social and developmental entity must endure, I argue, is the nostalgic hope for an adult world reconciled as free from conflict and human suffering. The paper conceptualizes how difficult it is for adults to separate their own conflicts of making a relationship to history from those of the adolescent learner and to encounter the adolescent as more than a story of historical consolation.
Living (Ek)statically: Educating-within-place and the Ecological Imagination
Authors: Kentel Jeanne Adele , Karrow Douglas
Published: November 2023

This paper explores the concept of educating-within-place, existentially derived through a series of immediate and direct experiences within several old growth forests in southern Ontario, and how this might inform notions of the ecological imagination. Our ruminations are guided by several ongoing research endeavours, some existential, others empirical. We take pause in order to examine what we have been doing in the field of Canadian curriculum studies whilst grasping towards a broadened perspective of teacher educating. To theoretically frame this pursuit we draw upon the notion of Ekstasis in order to engage in a pedagogy that considers possibilities through the senses and sensibilities of teacher candidates. In doing so we examine ways of being that move beyond the technocratic and cultivate a living curriculum.
La Figure de Terry Fox : Handicap et Performance et les Conséquences Pour l’Éducation
Authors: Schneider Cornelia
Published: November 2023

Cet article analyse la figure de Terry Fox par rapport à une reproduction idéologique d’un certain discours sur le handicap et sur l’infirmité à l’école. L’auteur reprend l’exemple du personnage de Terry Fox qui met en lumière certains aspects sociaux et culturels par rapport au handicap. L’analyse montre que la visibilité du handicap de Terry Fox est liée à sa performance physique et à des courants philanthropiques qui ont émergé dans les années 1980 et qui se sont maintenus, voire renforcés, depuis. Le handicap devient supportable quand il peut être « surmonté » et associé à de grandes causes qui transcendent le handicap. Ainsi, en enseignant de façon naïve l’histoire de Terry Fox et en encourageant la participation aux Courses Terry Fox dans les écoles, on renforce et on rend légitime un certain discours néolibéral qui cherche à former le citoyen consommateur individualiste capable de maîtriser son propre corps et son sort.

Collaborative Writing as an Exercise of Poetic Resistance in Teacher Education
Authors: Lund Darren E.
Published: November 2023

Over the last decade we have strived through a collaborative writing project to open a polyvocal and layered conversation on critical contemporary issues in teacher education, even as our program faced its demise. Our writing inquiries began as a critical thinking-through of the qualities of lived experiences as instructors within an innovative and now defunct teacher education program. The context for our work was a radically construed approach to teacher education that—in its language, form, and curriculum—challenged prevailing norms of practice. In our collaborative writing we confront the difficult work of teacher education, addressing specific challenges, complex demands, and forms of resistance that are prevalent in faculties of education everywhere. Such challenges include how we narrate alternative visions of teacher education, attend to issues of ethics and recognition, deal with the complexities of learning professional practice and take into account the larger, historical project of teacher education. As a provocative example of self-study research, our collaborative method of inquiry illustrates the richness and productivity of collaborative, poetic, practice-based research, oriented to critical issues in teacher education. The intentional effort to make our work public and politically provocative represents a deliberate attempt by the authors to reveal the importance of these critical conversations. We intend our conversations and thinking-through about practices in teacher education to remain open-ended and responsive to a plurality of thought and experience. Collaborative writing serves for us as a kind of resistance, reclaiming, re-storying, and historical accounting through encounters with others.

kistikwânihk êsko kitêhk: Storying Holistic Understandings in Education
Authors: Latremouille Jodi Marie , Bell Antonella , Kasamali Zahra , Krahn Mandy , Tait Lesley , Donald Dwayne
Published: November 2023

Learning alongside Dr. Dwayne Donald and Elder Bob Cardinal in a Holistic Understandings of Learning class held in Fall 2014 on Enoch Cree Nation evoked different ways of living well and wisely in the world. This course created a sacred place for the “four-part person” (mental, physical, emotional, and spiritual) to emerge, as we learned to pay deeper attention to the interconnectivity of creation in our educational practices. This multimedia métissage (Hasebe-Ludt, Chambers, & Leggo, 2009) combines life writing, readers’ theatre, and visual representations, weaving together our embodied responses to Elder Cardinal’s teachings. Each individual’s journey kistikwânihk êsko kitêhk (Cree: from head to heart) maintains its integrity and unique voice as it is intentionally woven into the Cree principles of meskanaw (pathway), miyo waskawewin (to walk in a good way), and the Blackfoot concept of aokakio’siit (being wisely aware).
Provoking Curricula of Care: Weaving Stories of Rupture Towards Repair
Authors: Jordan Nane , Richardson Pamela , Fisher R. Michael , Bickel Barbara , Walsh Susan
Published: November 2023

We are five scholars of education, provoking curriculum on the topic of “care”—as practice, theory, and struggle, through our stories of living, teaching, and learning. Our inquiries surface threads of rupture, where we find that “care” indicates our efforts to address suffering. Our care-work consists of restorative, creative, and contemplative practices. We tell our stories through a literary métissage (weaving) of creative non-fiction, poetic writing, artwork, and images. We thus creatively expand the meaning of care by evoking our understandings, lived experiences, and practices of caring. In this way, we hope to create more attuned relationships, and open the way for more stories of “care” to emerge.
Book Review: From Bricolage to Métissage: Rethinking Intercultural Approaches to Indigenous Environmental Education and Research
Authors: Vincent Adam
Published: November 2023

Gregory Lowan-Trudeau’s book From Bricolage to Métissage: Rethinking Intercultural Approaches to Indigenous Environmental Education and Research offers insights into métissage as a research methodology and explores issues of identity and ecology. His book provides a readily accessible understanding of who the Métis people in Canada are, and how taking what he calls the spirit of métissage, an approach which weaves multiple cultural perspectives together, can lead to greater and deeper understandings. This practice can also be built into teaching practices and be used to solve problems in various fields. The chapters which introduce Lowan-Trudeau’s research participants feel somewhat disjointed with the rest of the text, but provide various perspectives which will be of interest to those working in environmental education.
The Journey to Becoming an English Academic Writing Instructor as a Non-Native English-Speaking Teacher
Authors: Al Hariri Khalid
Published: November 2023

This presentation is an autoethnography that explores my identity as a non-native English-speaking writing instructor. The presentation narrates my feelings, opinions and observations about my educational journey from when I was an undergraduate student in the English department and first introduced to academic writing in English, to becoming a non-native English-speaking teacher (NNEST), until I became an English academic writing instructor. Throughout my years of teaching English to non-native speakers and teaching English academic writing, being foreign to the English language has always had a presence either in the way I identified myself or in the way my society labeled me. Society focused mainly on my non-nativeness to English. However, I was able to self-consciously see my strength of understanding and comparing the writing norms of my first culture with those of the target culture, which was reflected on my teaching in the classroom. Much of the research on NNESTs has focused on issues such as their pronunciation, vocabulary, students’ perceptions, but this study focuses on how I negotiated my identity in teaching writing.
Symposium: Critical Friendships, Poetic Relations: Weaving Inspirited Pathways Through the Academy
Authors: Latremouille Jodi , Bartlett Stephanie , Hanzel Stacey , Tait Lesley
Published: November 2023

In this symposium presentation, we explore how four women scholars are drawn to one another as a sustaining and life-giving practice in the hetero-patriarchal world of academia. Institutional attitudes, power, hierarchy and oppression (Betasamosake Simpson, 2014; Foucault, 2008; Kumashiro, 2002) hold both a visible and an invisible presence in the academy as individuals struggle with increasing workloads, institutional accountability and competition. We base our foundational understandings of these conditions in critical theory (Freire, 2000), and turn to ecology (Abram, 1996; Jardine, 2006; Macy & Brown, 2014) and Indigenous philosophies (Smith, 2012) for a response that is messy, heart-full, multivocal and rooted in good relations. We weave poetry and narrative writing to describe the well-worn pathways in the academy and to critically reflect on how we might step away from them to create fresh and renewed paths. Walking alongside each other in a courageous sisterhood, we see our criss-crossing footsteps, woven together like a braid, creating strength and new possibilities through relationships. We engage Indigenous and literary métissage (Donald, 2012; Hasebe-Ludt et al., 2009) as a form of life writing (Richardson & St. Pierre, 2005) and we will invite our audience into a dialogue that explores the deep influence of these relations on our well-being and success on our personal and academic journeys.
The Fecundity of Silence in Dialogue: Students’ Experiences of Classroom Discussions
Authors: Blackman Galicia Solon
Published: November 2023

Scholars have noted that literary studies ought to be marked by opportunities for students to engage with difficult topics. Arguably, class discussions are a signature pedagogy of literary studies that support engagement with difficult topics. However, silences can disrupt the anticipated insight of such discussions. How do students in higher education literary studies experience silence in such discussions? Can student silence be understood as a generative aspect of difficult conversations about literary texts? This research sought to disrupt established beliefs about the idea of silence as non-participation and to determine whether there is evidence that speaks to the fecundity of silence in discussions. Silence has not been studied nearly as much as dialogic pedagogy, but scholars recognize its value for literacy. My research is based on the conceptual frameworks of dialogic pedagogy and hermeneutics and methodologically uses hermeneutic interviewing to develop thick descriptions of students’ experiences. This presentation focuses on my preliminary findings with reference to the academic literature on student silence in dialogic teaching and learning contexts. I address confirmations and disconfirmations of prevailing academic perspectives and instructors’ assumptions that consider student silence as fecund. This research is relevant for instructors in literary studies but may have implications for other disciplines using dialogic pedagogy.
Digital Oral Histories for Reconciliation: The Nova Scotia Home for Colored Children History Education Initiative (DOHR)
Authors: Smith Tony , Morrison Gerald , Dorrington-Skinner Tracy , Llewellyn Kristina , Llewellyn Jennifer , Roberts-Smith Jennifer , Gibson Lindsay , Peck Carla
Published: November 2023

Digital Oral Histories for Reconciliation (DOHR) is a history education initiative to teach Grade 11 students about the Nova Scotia Home for Colored Children (NSHCC). The NSHCC, opened in 1921, was a segregated welfare institution for African Nova Scotian children. Residents suffered the effects of institutionalized racism in the Home throughout its 70 years. DOHR has partnered in the educational mandate of the restorative inquiry into the Home to co-design with the former residents a curriculum about their experiences (Province of Nova Scotia, 2015, p. 26). The purpose of the DOHR curriculum is for former residents to share their oral histories to develop students’ historical consciousness about institutionalized racism and to build right relations in their communities. The project was piloted in two Halifax area schools in October 2019. This symposium introduces attendees to the curriculum and shares initial findings from the pilot. Former residents share their impetus for the project, while other DOHR members share findings about the use of oral history—first person accounts of lived experiences with the past—as a restorative approach to redress of harms in education (e.g., Llewellyn & Llewellyn, 2015); how historical thinking lessons develop students’ historical consciousness—their sense-making of the past for orienting themselves to the present and future (Seixas 2004); and how DOHR’s use of virtual reality supports reconciliation with pedagogy-led (rather than technology-led) design principles (Kwon, 2019). To our knowledge, this is the first history education project centred on first-voice, to address reconciliation for African Nova Scotians.
An Overview of Darwinian Literary Studies: A New Science-Based Approach to Literature
Authors: Rizano Gindho , Yeni Marliza
Published: November 2023

This article discusses a newly emerging branch of literary criticism, Darwinian literary studies, an approach with a serious ambition to change the landscape of literary studies. It seeks to outline some of the approachâ€™s key contributions, such as explanations of possible origins of narrative and adaptive functions of literature as well as novel ways of interpreting individual works. This piece of writing also explores the controversies surrounding the approach, namely the stance that the approach takes against the postmodernist establishment and the criticism it receives. Regarding both the main ideas and the controversies, this paper seeks to answer and whether or not this approach is useful or relevant at all in todayâ€™s modern world.
Image of Bali from Western Perspective in Jamie James' A Tale of Bali and Elizabeth Gibert's Eat, Pray, Love
Authors: Seswita Seswita , Yeni Marliza
Published: November 2023

Many foreign writers have expressed their fascination with Bali in their works, among them are Jamie James in Andrew and Joey: a tale of Bali and Elizabeth Gilbert in Eat, Pray, Love. The two authors wrote about Bali from their personal experience dring their stay in that island. Some images created in the works are seen and analyzed through the prespective of Postcolonialism and New Criticism. This article presents how the two authors depicts Bali as an extravagant place in Eastern country which has adopted some Western values. The negative image is delivered to oppose the idea of Bali as the perfect island; moreover, as part of Indonesia, Bali still has some weaknesses to strengthen and truly support that it is part of Indonesia. The writer admits that this article is far from perfect. Due to the limitation of thinking and time, some more aspects can be explored more profoundly in terms of the image of Bali in these two works. Hence, there are still a lot of literary works that also talk about and discuss the image of Bali. Hopefully, there will be anyone who, willingly or even the writer himself, could continue the research and find out more about the images of Bali from the Western perspective as seen in some other novels and works.

Fast and accurate modeling of thermoset fracture by active learning quantum-chemical bond scission
Authors: Yu Zheng , Jackson Nicholas
Published: November 2023

A molecular understanding of thermoset fracture is crucial for enhancing performance and durability across applications. However, achieving accurate atomistic modeling of thermoset fracture remains computationally prohibitive due to the high cost associated with quantum mechanical methods for describing bond breaking. In this work, we introduce an active learning (AL) framework for our recently developed machine-learning based adaptable bond topology (MLABT) model that uses datasets generated via density functional theory (DFT) calculations that are both minimalistic and informative. Employing MLABT integrated with AL and DFT, we explore fracture behavior in highly crosslinked thermosets, assessing the variations in fracture behavior induced by system temperature, temperature fluctuations, strain rate, cooling rate, and degree of crosslinking. Notably, we discover that while fracture is minimally affected by temperature, it is strongly influenced by strain rate, suggesting the absence of the time-temperature superposition in thermoset plasticity. Furthermore, while the structural disparities introduced by different network annealing rates influence the elastic properties, they are inconsequential for thermoset fracture. In contrast, network topology emerges as the dominant determinant of fracture, influencing both the ultimate strain and stress. The integration of MLABT with the AL framework paves the way for efficient and DFT-accurate modeling of thermoset fracture, providing an affordable and accurate approach for calculating polymer network fracture across chemical space.
IR of Vanillin: A classic study with a twist
Authors: Nicolaou Michael , Seen Hans , Gibson Emma , Vilà-Nadal Laia
Published: November 2023

In this research, we delve into the vibrational spectroscopy of vanillin, a widely used aromatic and flavouring agent, through a comprehensive computational analysis. We employ a variety of common computational chemistry functionals and basis sets to calculate the infrared (IR) and Raman spectra of vanillin, aiming to shed light on its structural and spectroscopic properties. Our investigation entails benchmarking these theoretical results against one another to identify the most accurate computational approach. Furthermore, we juxtapose our theoretical findings with experimental IR and Raman spectra to evaluate the degree of agreement between theory and experiment. This comparative analysis provides insights into the reliability of the chosen computational methods in capturing the vibrational behaviour of vanillin, a crucial aspect for applications in the food and pharmaceutical industries. In future work we plan to expand this study to other compounds aiming to bridge the gap between theory and experiment, this study contributes to a deeper understanding of vanillin's molecular behaviour, ultimately enhancing our knowledge of its sensory and chemical attributes.
Optimisation of Process Parameters on Tensile Strength of 3D Printed Polylactic Acid (PLA) Parts: ASTM D638 Type – IV
Authors: Akpakpavi M. K. , Sackey S. M. , Asante-Afrifa M. K.
Published: November 2023

Purpose: The purpose of this study is to optimize the influence of 3D printing processing parameters on the ultimate tensile strength of 3D printed Polylactic Acid (PLA) parts. The objective is to develop predictive models to help predict and attain optimised mechanical strength integrity of 3D printed parts.

Design/Methodology/Approach: In the present study, 3D printed PLA samples were modelled and fabricated using carefully selected processing parameters-processing speed, processing temperature and nozzle diameter. Tensile tests were performed by ASTM D638 standard. Two characteristics response optimisation models based on Taguchi Technique and multi-linear regression models were developed to optimise the process parameters and the ultimate tensile strength of the 3D printed samples.

Findings: Results of this study reveal that ultimate tensile strength is significantly affected by the Nozzle diameter. The ultimate tensile strength of the 3D-printed PLA sample was found to be significantly higher than the strength of the original PLA filament printed.

Research Implications/Limitations: In this study, only three critical 3D printing processing parameters including, processing speed; processing temperature and nozzle diameter were implemented concurrently.

Practical implication: The optimisation of process parameters for enhancing the tensile strength of 3D-printed PLA parts holds significant practical consequences, including cost savings, improved performance, sustainability, and innovation. The aforementioned consequences render PLA a more feasible and appealing material option for a diverse array of applications and industries.

Social implication: Optimisation of PLA printing can promote community engagement by allowing individuals to bring their creative ideas to life, fostering a sense of community and innovation.

Originality / Value: The unique aspect of this research resides in its particular emphasis on PLA, the utilization of empirical and data-based techniques to optimise process parameters, and its potential to enhance the real-world implementation of 3D printing with PLA across diverse industries.

Designing Smart Antennas Using Machine Learning Algorithms
Authors: Samantaray Barsa , Das Kunal Kumar , Roy Jibendu Sekhar
Published: November 2023

Smart antenna technologies improve spectral efficiency, security, energy efficiency, and overall service quality in cellular networks by utilizing signal processing algorithms that provide radiation beams to users while producing nulls for interferers. In this paper, the performance of such ML solutions as the support vector machine (SVM) algorithm, the artificial neural network (ANN), the ensemble algorithm (EA), and the decision tree (DT) algorithm used for forming the beam of smart antennas are compared. A smart antenna array made up of 10 half-wave dipoles is considered. The ANN method is better than the remaining approaches when it comes to achieving beam and null directions, whereas EA offers better performance in terms of reducing the side lobe level (SLL). The maximum SLL is achieved using EA for all the user directions. The performance of the ANN algorithm in terms of forming the beam of a smart antenna is also compared with that of the variable-step size adaptive algorithm.

Changes in the Relation Between ESG and Expected Returns According to ESG Awareness Levels
Authors: Lee Eun Jung , Lee Yu Kyung
Published: November 2023

The COVID-19 pandemic has triggered an increased awareness and interest in ESG (Environmental, Social, Governance) among investors in the Korean market. Consequently, this study examines the changes in investors’ tastes and preferences regarding ESG before and after COVID-19 and analyzes how these changes affect the relationship between ESG and expected returns. The analysis revealed that, before COVID-19 the excess returns of portfolios constructed by buying stocks with high ESG scores and selling stocks with low ESG scores were not statistically significant. However, after COVID-19 the excess returns of these portfolios were significantly positive. This result suggests that prior to the pandemic, investors did not perceive ESG as a risk and showed no preference for ESG investments, leading to insignificant excess returns close to zero. In contrast, after the COVID-19 pandemic, increased interest in ESG resulted in a shift in investor preferences, leading to positive excess returns in ESG investments. The results remain consistent even after controlling for firm characteristics. Furthermore, when we examine the impact of each ESG component on expected returns separately, we find that heightened interest in environmental and social factors has a significant positive effect on expected returns.

ensino de Sociologia no contexto de ascensão da extrema direita no Brasil
Authors: Bodart Cristiano das Neves , Pires Welkson
Published: November 2023

Este artigo apresenta o lugar e o papel da Sociologia escolar no atual contexto brasileiro, marcado pela ascensão de ideologias e práticas de extrema direita, mais especificamente pelo seu viés econômico ultraliberal e pelo conservadorismo moral. Organizado em três partes, esboça, respectivamente, o cenário macro político, curricular e alguns dos seus desdobramentos nas práticas escolares. O esforço maior está em refletir sobre as formas como a Sociologia escolar tem sido – ambiguamente – compreendida e instrumentalizada no contexto brasileiro. As reflexões estão amparadas, além da revisão de literatura, na análise de conjuntura, nos encaminhamentos político-institucionais, nos documentos curriculares e em relatos de experiências docentes coletados no ano de 2022.

Penelitian tentang formulasi body scrub dari sari ubi jalar ungu sebagai bahan pembuatan body scrub  dengan penambahan  scrubber beras ketan putih. Body scrub adalah sediaan farmasi berupa produk kecantikan yang berfungsi untuk menghaluskan kulit tubuh dan mengangkat sel-sel kulit rusak dengan bantuan bahan scrub. Ubi jalar ungu (Ipomoea batatas L.) varietas ayamurasaki banyak mengandung zat warna, terutama pigmen antosianin yang merupakan antioksidan alami yang dapat mencegah penyakit kanker, jantung, tekanan darah tinggi, dan bahkan dapat menghaluskan kulit. Pembuatan sari ubi jalar ungu dilakukan dengan cara pengupasan kulit ubi jalar ungu, setelah itu dibersihkan dan dihaluskan dan diperas ubinya sampai menjadi sari. Penelitian ini sudah pernah dilakukan sebelumnya, yang belum pernah dilakukan yaitu tentang pengaruh waktu pengadukan. Penelitian ini bertujuan untuk memanfaatkan sari ubi jalar ungu untuk pembuatan body scrub dengan konsentrasi sari ubi jalar ungu 40 gram, 50 gram, dan 60 gram sedangkan konsentrasi granul beras ketan 60 gram, 50 gram, dan 40 gram. Pengujian sediaan ini meliputi uji organoleptik. Uji pH, uji tipe emulsi, uji daya sebar, dan uji homogenitas. Hasil penelitian menunjukkan sediaan yang memenuhi evaluasi fisik  dan daya sebar adalah dengan perbandingan konsentrasi sari ubi jalar ungu dan granul beras ketan 60 : 40 gram, 50 : 40 gram, dan 60 : 50 gram dengan tekstur semi padat, berwarna coklat dan berbau khas. Hasil uji tipe emulsi menunjukkan bahwa body scrub itu termasuk minyak dalam air dan untuk uji homogenitas body scrub itu homogen.

Antioksidan adalah zat yang dibutuhkan untuk menetralkan radikal bebas dan mencegah kerusakan akibat radikal bebas. Banyak tumbuhan yang telah terbukti bermanfaat dalam melindungi tubuh manusia dari bahaya radikal bebas karena tumbuhan tersebut mengandung antioksidan. Biji tanaman juga mengandung senyawa fitokimia seperti fenol, flavonoid dan tanin, yang mencegah produksi radikal bebas yang berlebihan dan dapat berperan sebagai antioksidan, termasuk biji kelengkeng. Penelitian tentang ekstrak tanaman kelengkeng sudah dilakukan sebelumnya, penelitian yang belum dilaporkan yaitu pengaruh perbedaan metode ekstraksi biji kelengkeng (dimocarpus longan.) terhadap aktivitas antioksidan. Penelitian ini bertujuan menganalisa pengaruh perbedaan metode ekstraksi terhadap aktivtas antioksdan yang akan dihasilkan. Penelitian ini memvariasikan metode yaitu maserasi dan refluks, serta memvariasikan waktu yaitu maserasi 1 hari, 2 hari, 3 hari, kemudian refluks 30 menit, 90 menit, dan 120 menit dimana keduanya dilakukan perbandingan larutan terhadap tiap sampel yaitu 1:9, 1:10, 1:11, dan 1:12. Kemudian dianalisa sifat organoleptiknya, rendemen, aktivitas antioksidan, dan analisa GCMS. Hasil penelitian ini menunjukkan bahwa ekstrak dengan nilai IC50 tertinggi sebesar 23,7464 µg/mL dari metode refluks yang didapat dari perbandingan pelarut dan serbuk biji kelengkeng 1 : 11 dari reaksi selama 120 menit, sedangkan hasil dari proses metode maserasi mendapatkan hasil IC50 yatu 33,29125 µg/mL dari reaksi 2 hari dengan perbandingan pelarut dan serbuk biji kelengkeng 1:11. Hasil GC-MS membuktikan bahwa hasil ekstrak biji kelengkeng yang diperoleh terdiri dari beberapa jenis asam lemak dan metil ester, dimana asam lemak utama yang terdapat pada ekstrak biji kelengkeng yaitu elaidic acid sebesar 14,65% dan palmatic acid sebesar 13,38% yang berpotensi menjasikan ekstrak biji kelengkeng ini bahan baku sebagai biodiesel. Kata Kun
