Community service activities are going well, the students of SMK Bina Nusa Slawi have understood and understand the benefits of lime and star fruit that grow in the surrounding environment as antibacterials, are aware of a healthy and clean lifestyle to prevent the transmission of bacteria and viruses, and have skills in making hand sanitizer as a health product
Pembelajaran Integral Tak Tentu Menggunakan Articulate Storyline di MA Miftahussalam
Get PDFMathematics is often considered a difficult subject and is of little interest to students, which results in students having difficulty learning independently outside of school. The difficulty of class XI students in understanding mathematics material is the background for the need to use new technology, namely articulate storylines, so that mathematics learning is more innovative and interactive. This community service activity is divided into 2 stages, namely the preparation stage and the implementation stage. In the preparation stage, the community service team conducted interviews with class XI mathematics teachers at MA Miftahussaam to find out what material was still difficult for students to understand. The second stage of this community service activity is the implementation stage which includes a pre-test, providing learning companion modules, playing the Articulate Storyline video, and post-test. The results of community service regarding the use of Articulate Storyline media at MA Miftahussalam show that the average pre-test score of 25 students is 42.2. This average value shows that the level of students' understanding ability and interest in learning about Indefinite Integral material is still below the average standard, namely less than 50. Meanwhile, the average post-test score of 25 students is 72.2. This average value shows that the level of students' understanding ability and interest in learning about Integral Uncertain material has reached the standard value, namely more than 70. Meanwhile, if calculated using percentages, the percentage increase in value from pre-test to post-test is 71.09%. This percentage level can be stated to be quite good
Existential Feminism in Priscilla: Patriarchy, Identity, and The Making of “the Other”
Get PDFPatriarchy systematically constructs women’s identities through control and subjugation, often reducing them to “the Other” or a secondary figure defined by men. This research applies existential feminist theory to analyze Sofia Coppola’s Priscilla (2023), focusing on how patriarchal systems fabricate the identity of the female subject as “the Other,” a subordinate figure defined by men. The research investigates how the film portrays Priscilla’s character and transformation from a passive figure into a selfaware individual who reclaims her identity, exploring how systems enforce power, identity, and gender roles. Findings suggest that the film visualizes Priscilla’s internal and external conflicts in the context of love and fame under Elvis Presley’s dominance, utilizing narrative to critique forms of systemic othering while opening a space for female subjectivity and resistance. Positioning the film within feminist discourse, this research challenges patriarchal ideologies that marginalize women and instead foregrounds identity as a site of performance and resistance
Mapping Truth and Lies: A Forensic Linguistic Analysis of Verbal and Non-Verbal Cues in Student Interviews
Get PDFThis study is the preliminary stage of a series of research projects attempting to develop a lie detection model in student interviews using a forensic linguistic approach. In this study, researchers focused on the differences between truth-telling and lying, as seen from the discourse and non-verbal cues. The data were taken from audio and video recordings of interviews with 20 students who were asked to draw two types of lots. The first draw required the students to either (1) take the envelope and the money inside it or (2) leave the envelope. The second draw required the students to either (1) tell the truth or (2) tell lies during the entire interview session. They were not allowed to show their draw results to anyone, until the end of the interview sessions. The researchers then analysed the discourse and non-verbal cues of the interview results. The theoretical framework used includes the Discourse Open-ness Theory (Fraser, 1990) to analyse the use of discourse markers that provide clues related to honesty or deception in conversation. The Illusion of Honesty Theory (Ekman, 2001) identifies non-verbal cues such as eye contact, gestures, and postures that are often associated with lying. Vrij’s Deception Theory (2008) introduces language strategies commonly used in lying and supports a deeper analysis of the verbal and non-verbal elements found in dishonest interactions. A forensic linguistic approach (Coulthard & Johnson, 2007) is applied to examine sentence structures and other linguistic features that often emerge in deceptive communication. The results of this study show that inconsistent answers, evasions, short and less detailed responses, longer response times, minimal eye contact, rigid or frequently shifting body positions, and nervous smiles are all indications of lies. In contrast, detailed, longer, and consistent responses, direct eye contact, and relaxed posture indicate truth-telling
Evaluating PCA and LDA to Improve Machine Learning Classification of Consumer Behavior in Health Informatics
Get PDFBehavioral data derived from consumer activity offer significant potential in health informatics, particularly for developing predictive models related to lifestyle, adherence, and patient engagement. This study evaluates the effect of two widely used dimensionality reduction techniques, namely principal component analysis (PCA) and linear discriminant analysis (LDA) on the performance of five supervised machine learning classifiers: logistic regression (LR), support vector machine (SVM), naive bayes (NB), decision tree (DT), and random forest (RF). The experimental dataset, although sourced from a commercial context, contains demographic and economic attributes commonly found in health-related behavioral data, such as age and income. Results indicate that LDA significantly improves classification performance across all models, with Random Forest achieving the highest scores: accuracy = 0.91, precision = 0.88, recall = 0.85, F1-score = 0.86, and AUC = 0.95 when trained on LDA-transformed features. SVM also performed competitively under the same configuration (AUC = 0.94). Conversely, PCA provided moderate gains but underperformed in capturing class-discriminative information compared to LDA. These findings demonstrate that integrating LDA with robust classifiers such as RF and SVM enhances both predictive accuracy and model interpretability, offering practical benefits for behavior-informed health decision support systems. The study highlights the relevance of supervised feature transformation in optimizing data pipelines for personalized healthcare applications

ISOLASI DAN IDENTIFIKASI SALMONELLA SP. PADA DAGING AYAM BROILER DI PASAR TRADISIONAL X
Get PDFDaging ayam adalah sumber protein yang kaya akan vitamin dan mineral untuk mendukung pertumbuhan, pemulihan jaringan, serta menjaga kesehatan tubuh. Meski demikian, proses memasak, penyimpanan, dan penanganan yang kurang tepat dapat mengurangi kandungan nutrisi seperti vitamin dan protein. Selain itu, daging ayam rentan terhadap kontaminasi bakteri Salmonella sp., yang dapat menyebabkan infeksi usus. Penelitian dilakukan di Pasar X, diketahui memiliki kondisi sanitasi yang buruk. Pasar tampak kumuh, banyak lalat yang mengerubungi daging, dan penanganan kebersihan oleh pedagang kurang diperhatikan. Sebanyak dua puluh empat sampel daging ayam dari empat pasar tradisional X dipilih secara acak untuk diuji melaluiberbagai langkah. Tujuan penelitian ini adalah untuk mengidentifikasi dan mengisolasi bakteri Salmonella sp. dari daging ayam broiler yang dijual di Pasar Tradisional Kabupaten X menggunakan metode SNI ISO 6579-1-2017. Metode ini dipilih karena memiliki standar prosedur yang lebih akurat untuk mendeteksi keberadaan Salmonella sp. Tahap pre-enrichment menggunakan BPW, pengayaan dengan RVS dan MKTTn, isolasi pada media selektif XLD dan HE, serta konfirmasi melalui pewarnaan Gram dan uji biokimia (Indol, MR, VP, TSIA, dan SCA). Hasil penelitian menunjukkan 7 dari 24 sampel positif mengandung Salmonella sp., dengan ciri-ciri koloni hitam, Gram negatif berbentuk batang, serta hasil uji biokimia yang sesuai dengan karakteristik Salmonella sp. Penelitian ini menegaskan bahwa sanitasi lingkungan dan akses terhadap air bersih sangat memengaruhi tingkat kontaminasi. Pedagang yang berjualan di dalampasar cenderung memiliki kondisi kebersihan lebih baik dibandingkan pedagang yang berjualan di sekitar area luar pasar
