Abstract

Salah satu parameter utama dalam kualitas citra CT scan untuk penegakan diagnosa adalah   resolusi kontras tinggi, yang dinyatakan dengan Modulation Transfer Function (MTF) dan resolusi kontras rendah, yang dinyatakan dalam contrast-to-noise ratio (CNR). MTF dan CNR menjadi kriteria penting untuk membandingkan protokol dosis tinggi dan dosis rendah, yang bergantung pada karakteristik obyek target. MTF mengkarakterisasi tingkat keburaman pada domain frekuensi sedangkan CNR mengkuantifikasi detektabilitas objek-objek kontras rendah. Penelitian ini menggunakan fantom American Association of Medical Physicists in Medicine (AAPM) sebagai obyek dengan variasi arus tabung dan tebal irisan. Citra dianalisis dengan software Radiant DICOM dan IndoQCT. Pengukuran dilakukan dengan dua variasi yaitu arus tabung 100, 130 dan 150 mA pada tegangan tabung 80 kV dan tebal irisan 2,5 mm. Sedangkan untuk variasi tebal irisan 1,25, 3,75, dan 5 mm pada tegangan tabung 80 kV dan arus tabung 125 mA. Hasil penelitian menunjukkan nilai MTF10 masing-masing variasi arus tabung berturut-turut 0,7 line/mm; 0,7 line/mm; dan 0,8 line/mm. Nilai MTF masing-masing variasi tebal irisan sama yaitu 0,7 line/mm. Nilai CNR pada variasi arus tabung sebesar 2,548; 3,016; dan 3,482 serta pada variasi tebal irisan diperoleh 2,308; 2,613; dan 2,735. Semakin besar nilai arus tabung dan tebal irisan, maka nilai MTF semakin tinggi demikian pula untuk nilai CNR.

Abstract

This study aims to examine the integrated marketing communication strategy employed by Kedai Pempek Salisah in introducing pempek—a traditional Palembang dish—in Blitar, a city with a distinct cultural background. Drawing on perception theory and integrated marketing communication, and using a descriptive qualitative approach within a constructivist paradigm, the study finds that Salisah's success lies in preserving the cultural identity of pempek while adapting to local tastes. Consistent communication strategies through social media, word of mouth, taste adjustments, and relatable promotional language help build emotional connections with consumers. The study concludes that effective intercultural communication in culinary marketing requires a balance between cultural preservation and contextual adaptation.

Abstract

In the digital era, media plays an essential role in shaping public opinion, with alternative media platforms emerging as key players in critiquing government policies. Among these, satirical content has gained significant traction as a method of social critique. This study investigates MEET NITE LIVE, an Indonesian satirical program, to understand how humor and framing techniques are employed to critique government policies and influence public perceptions. By utilizing a qualitative approach that combines Critical Discourse Analysis (CDA) and Content Analysis, the study explores how the host uses satirical humor—particularly irony, sarcasm, and parody—to frame government policies, highlighting inefficiencies, injustices, and contradictions, particularly within the economic and educational sectors.  The research reveals that the humor in MEET NITE LIVE goes beyond mere entertainment. It serves as a tool for social critique, encouraging the audience to critically reflect on pressing socio-political issues. By using humor to expose the flaws in government actions, the show fosters a deeper public awareness, prompting meaningful discussions about the implications of these policies.  This study contributes to a deeper understanding of how satirical media, specifically through programs like MEET NITE LIVE, functions as a tool for political discourse. By analyzing the specific humor techniques employed, such as irony, sarcasm, and parody, the research reveals how satirical content critically engages the public with government policies. It demonstrates the potential of satire not only to entertain but also to stimulate critical reflection on socio-political issues, thereby encouraging a more informed and active public engagement with the implications of government actions  The findings highlight the importance of alternative media in providing a space for open critique, allowing the public to engage with social and political issues that are often overlooked or constrained by mainstream media. These findings emphasize the role of alternative media in expanding the public discourse, which in turn can have a significant impact on shaping opinions and policies.
