UJI EFEKTIVITAS EKSTRAK ETANOL 70% DAUN MATOA (Pometia pinnata) SEBAGAI ANTIHIPERGLIKEMIA PADA MENCIT JANTAN (Mus muculus)
Full text linkHyperglycemia is one of the main clinical symptoms of diabetes mellitus. The use of herbal medicine can be an additional therapy to address this condition. Matoa leaves (Pometia pinnata) have the potential to lower blood glucose levels. The active compounds in the extract of matoa leaves, such as flavonoids are effective as antihyperglycemic agents. This study aims to determine the effectiveness of matoa leaf extract (Pometia pinnata) using the soxhlet extraction method as antihyperglycemic in male mice (Mus musculus). This study employs an experimental research design with a pre-test and post-test controlled group design involving 25 mice. Matoa leaves are extracted using the soxhlet method with 70% ethanol, resulting in a yield of 20.51% of concentrated extract. Glucose levels are measured every 30, 60, 90, and 120 minutes, and the results are analyzed using SPSS software for One Way Anova test if the data is normally distributed and homogeneous, then followed by Tukey's Test. The results of the study indicate that the leaf extract of Matoa obtained through the soxhletation method is effective as an antihyperglycemic agent in mice induced with 20% glucose. The average decrease in blood glucose levels at a dose of 200 mg/KgBB is 105,8 mg/dL, at a dose of 300 mg/KgBB is 112.4 mg/dL, and at a dose of 400 mg/KgBB is 118 mg/dL.Hiperglikemia merupakan salah satu gejala klinis utama pada penyakit diabetes melitus.

ENHANCING ELEMENTARY SCHOOL STUDENTS’ SPEAKING SKILLS THROUGH CONTEXTUALIZING VOCABULARY IN LUCA CARTOON MOVIES
Full text linkThis study examined how well Luca cartoons work to enhance the oral skills of elementary school students, paying special attention to vocabulary and pronunciation. The event took place at a Sidoarjo-based private Islamic elementary school. A mixed method approach including quantitative and qualitative data was used in this investigation. Twenty-five second-graders took part in the study, which used Luca cartoons as a teaching tool for eight treatment sessions. While observations evaluated motivation, engagement, listening comprehension, vocabulary acquisition, emotional reactions, interactions, and follow-up activities, pre-tests and post-tests evaluated vocabulary and pronunciation progress. Both vocabulary (from a mean score of 5.56 before the test to a mean score of 8.26 after the exam) and pronunciation (from a mean score of 5.16 before the test to a mean score of 7.82 after the test) shown notable increases, according to the results. Approximately 91% of the pupils engaged in active participation and shown desire and curiosity. The majority of kids demonstrated strong listening comprehension, picked up new vocabulary, and expressed interest in words they were unfamiliar with. Positive emotional responses made studying English more enjoyable. The students' enthusiastic participation and application of the English expressions they had learnt from the video were demonstrated by the post-film discussion. Although the terminology was not consistently transferred to other settings, the follow-up exercises successfully improved memory and summary abilities. According to the study's findings, adding Luca cartoons to the curriculum can make learning more fun and efficient while also greatly enhancing students' motivation, engagement, and speaking abilities. Thus, it's critical to keep considering individual characteristics when creating new teaching methods to guarantee that every student gains an equal advantage

Visual Parody of Decolonization: Reading the Hybridity of Colonial Symbols in the “Tujuh Belasan” Commemorations
Full text linkABSTRACT
Indonesia’s Independence Day celebrations—popularly known as Tujuh Belasan—often feature theatrical performances that restage battles between Japanese troops, Allied forces, and Indonesian freedom fighters. In these performances, military costumes and props are crafted manually by local hands, turning narrow village alleys into symbolic stages. While they may appear to be mere entertainment, such reenactments, when viewed through the lens of complex postcolonial understanding, function as visual parodies of decolonization. Drawing on Homi K. Bhabha’s concepts of mimicry and the third space, these performances expose ironic fissures that unsettle colonial authority. They transform colonial imagery from symbols of domination into objects of mockery, hybridity, and creative contestation. Through Gillian Rose’s notion of the site of production, this study highlights how the making of costumes and theatrical paraphernalia generates visual meaning beyond institutional control, embedding local participation and creativity in the reinterpretation of history. This research employs a qualitative approach combining visual studies and ethnographic observation to examine how vernacular visual forms negotiate power, memory, and identity. The result is a form of visual parody that acts as a grassroots strategy of decolonizing historical imagination—using design as a tool to subvert dominant colonial narratives and to reconstruct the past in ways that are playful, hybrid, and deeply rooted in local collective agency.
ABSTRAK
Perayaan Hari Kemerdekaan Indonesia yang populer disebut Tujuh Belasan sering menampilkan pertunjukan teatrikal yang merekonstruksi pertempuran antara pasukan Jepang, Sekutu, melawan pejuang kemerdekaan Indonesia. Di pertunjukan itu kostum dan properti militer dibuat secara manual oleh tangan-tangan lokal yang mengubah lorong perkampungan menjadi panggung simbolik. Walau tampak sebagai hiburan semata, pertunjukan itu dalam perspektif pemahaman pascakolonial yang kompleks adalah bentuk parodi visual terhadap dekolonisasi. Menggunakan konsep mimicry dan third space dari Homi K. Bhabha, reenactment semacam itu mempertontonkan celah-celah ironis yang mengguncang otoritas kolonial. Menjadikan citra-citra kolonial bukan lagi simbol dominasi, melainkan objek olok-olok, hibriditas, dan perebutan makna secara kreatif. Melalui konsep site of production dari Gillian Rose, penelitian ini menyoroti bagaimana proses produksi kostum dan pernak-pernik impresi teatrikal membentuk makna visual di luar kendali institusional, menanamkan partisipasi dan kreativitas lokal dalam penafsiran ulang sejarah. Penelitian ini kualitatif melalui studi visual dan observasi etnografis, yang mengkaji bagaimana bentuk-bentuk visual vernakular bernegosiasi dengan kekuasaan, ingatan, dan identitas. Hal itu menjadi ungkapan parodi visual yang berfungsi sebagai strategi dekolonisasi imajinasi sejarah yang muncul dari bawah. Dimana menjadikan desain sebagai alat untuk menumbangkan narasi dominan kolonial dan merekonstruksi masa lalu secara jenaka, hibrid, dan penuh agensi kolektif khas lokalitas
Oversharing dan Resiko Phishing: Tinjauan Perilaku Bermedia Sosial Mahasiswa di Salatiga
Full text linkABSTRACT
The rapid growth of social media has transformed how individuals communicate and manage personal information, while also creating space for oversharing that is often carried out without a clear awareness of its risks. Oversharing opens opportunities for digital crimes such as phishing, especially when users, including university students, fail to manage their privacy boundaries properly. This study aims to analyze how students’ oversharing practices on social media increase their vulnerability to phishing by using Communication Privacy Management (CPM) theory as the main framework, particularly through the concepts of boundary rules, co-ownership, and boundary turbulence. This research adopts a descriptive qualitative approach with a constructivist paradigm and involves 40 informants from four universities in Salatiga. Data were collected through in-depth interviews and analyzed using thematic analysis. The findings show that most students understand the idea of oversharing, yet they continue to engage in it for social recognition and self-expression. Many of them do not have clear boundary rules in deciding who can access their personal information and to what extent it can be shared, which leads them to unintentionally disclose sensitive data such as location, identity, and daily routines.Once personal information has been shared and becomes co-owned by others, weak coordination over how that information is used can trigger boundary turbulence, creating opportunities for data misuse in the form of phishing. Theoretically, this study reinforces the relevance of CPM in explaining students’ digital privacy management; practically, it underscores the importance of digital literacy and stronger privacy policies in higher education settings.
ABSTRAK
Perkembangan media sosial telah mengubah cara individu berkomunikasi dan mengelola informasi pribadi, sekaligus membuka ruang bagi fenomena oversharing yang sering kali tidak disadari risikonya. Oversharing menciptakan peluang bagi tindakan kriminal digital seperti phishing, terutama ketika batas privasi tidak dikelola dengan baik oleh pengguna, termasuk mahasiswa. Penelitian ini bertujuan menganalisis bagaimana praktik oversharing mahasiswa di media sosial meningkatkan kerentanan terhadap phishing dengan menggunakan teori Communication Privacy Management (CPM) sebagai kerangka utama, khususnya melalui konsep boundary rules, co-ownership, dan boundary turbulence. Penelitian ini menggunakan pendekatan kualitatif deskriptif dengan paradigma konstruktivisme, melibatkan 40 informan dari empat perguruan tinggi di Kota Salatiga. Data dikumpulkan melalui wawancara mendalam dan dianalisis menggunakan analisis tematik. Hasil penelitian menunjukkan bahwa sebagian besar mahasiswa memahami konsep oversharing, tetapi tetap melakukannya demi pengakuan sosial dan ekspresi diri. Banyak dari mereka belum memiliki boundary rules yang jelas dalam menentukan siapa yang boleh mengakses informasi pribadi dan sejauh mana informasi tersebut dibagikan, sehingga secara tidak sadar mengungkapkan data sensitif seperti lokasi, identitas, dan kebiasaan sehari-hari. Ketika informasi pribadi telah dibagikan dan menjadi co-ownership dengan orang lain, lemahnya koordinasi penggunaan informasi memicu boundary turbulence yang membuka peluang penyalahgunaan data dalam bentuk phishing. Secara teoretis, penelitian ini menegaskan relevansi CPM dalam menjelaskan pengelolaan privasi digital mahasiswa serta secara praktis, menyoroti pentingnya literasi digital dan penguatan kebijakan privasi di lingkungan perguruan tinggi
HOW SOON THE ENVIRONMENTAL PERFORMANCE CAN CREATE FIRM'S VALUE IN ASIA
Full text linkResearch Purposes. This study aims to investigate the effect of Environmental performance on the financial performance of companies in sectors sensitive to natural issues in Asia, for the current year, the following year, and two years after.
Research Methods. The study employs quantitative methods, utilizing secondary data and regression analyses.
Research Results and Findings. The results of this study indicate that environmental performance has a significant negative impact on financial performance, and the moderating variable of Women on Board does not strengthen the relationship between environmental performance and financial performance. This outcome may be attributed to the costs of improving environmental performance not being commensurate with their impact on financial performance. Furthermore, the influence of women on boards may be limited because there may not be many strategic positions within these companies held by women. The implications of these findings are to provide guidance for corporate decision-making in addressing sustainability issues through corporate financial performance, while still maximizing the financial performance of companies, particularly in Asian firms sensitive to natural resource issues

ACUTE APPENDICITIS: IS SURGERY STILL THE BEST OPTION? SPECIAL CONSIDERATION ON PEDIATRIC AND PREGNANT PATIENTS
Full text linkAcute appendicitis, being one of the most prevalent sources of the acute abdomen in adult and pediatric patients, is marked by inflammation of the remnant of vermiform appendix. Combine the pregnancy and general surgery cases, acute appendicitis is also of the leading concern. For more than 10 decades, open surgery was the solely normative treatment for acute appendicitis. Nonoperative management (NOM) is a master plan in which patients get anti-microbials with the point of averting surgery. Appendectomy is set aside for patient who do not response to anti-microbials or undergo relapse of appendicitis. But the decision to conduct NOM increased since the outbreak of COVID-19 until now. NOM is suitable in first attack patients who have a clinical sign of merely appendicitis without bodily discoveries of diffuse peritonitis or proof of imaging of enormous abscess, phlegmon, perforation, or tumor. The limited contraindications to NOM are of patient who has delayed response to anti-microbials, those with appendicolith finding, and older patients because of higher chance to have a latent malignancy. Treatment failure clinically or radiographically, as prove by obstruction of the bowel, sepsis, or constant ache, pyrexia, or leukocytosis, necessitates prompt appendectomy. NOM may be a choice for children who can describe their symptoms verbally, have a trustworthy and reproducible abdominal examination, and after shared decision-making among the overseeing pediatric surgeon and the parents/primary caregivers. Successful rate of NOM in child patient is about 67% to 91%. The customary treatment of acute appendicitis in pregnancy is still appendectomy, with laparoscopic appendectomy preferable than open appendectomy. The selection of strategy is based on the clinical status and inclinations, gestational age, and the surgeon's experience degree. Under considerations of gestational age, NOM was more frequently chosen than appendectomy in the first and third trimesters. Overall successful rate of NOM is 93%
