Background: Body image is related to adolescent food preferences, which determine their nutritional status. Peri-urban areas might have different adolescents' snacking habits, strict diets, nutritional status, and body image. Objectives: This study aimed to analyze the association between adolescents' snacking habits, implementation of a strict diet, and nutritional status on their body image. Methods: This study used a mix-method, a combination of the quantitative and qualitative survey with a cross-sectional design. A total of 39 adolescents aged 15-18 who live in the peri-urban areas of Depok and Bogor were consecutively selected. The study was conducted in January 2022. Quantitative data include respondents' characteristics, body weight and height, snacking habits, and body image. Qualitative data collected were types of snacks, their reasons for buying snacks, and perceptions of ideal weight. Results: The nutritional status of the respondents was underweighted (5%), normal (92%), and overweight (3%), with snacking frequency 4-7 times/week (59%) with a weekly snacking expenditure of IDR 15,000 – 30,000 (49 %). As many as 23% of respondents performed a strict diet and perceived having a thin (21%) and fat (23%) body image. Adolescents with normal nutritional status were perceived as having fat (20.5%) and thin (15.4%) body image (p: 0,0215). There was also a relationship between diet (p: 0.0084) and weekly snacking expenditure (p: 0.0152) with body image, and there was no relationship between snacking frequency (p: 0.3123) and daily meal frequency (p-value=0.3972) with body image.  Conclusions: A wrong perception of body image from actual nutritional status can affect snacking habits and the implementation of a strict diet among adolescents.

Handwashing with Soap Practice (HWWS) to prevent the infection of Covid-19 is very low in eastern Indonesia. Triggering community behavior change of HWWS is necessary, especially to make them consistent and sustainable. This community service activity uses Participatory Rural Appraisal (PRA), which combines 14 methods. This study recruited 74 respondents in rural areas of Manggarai (NTT) and Sumbawa (NTB). To evaluate their HWWS behavioral change, we conducted a pre-and post-test on their knowledge, attitude, and practice. Results showed that there was a significant change in their HWWS practice in critical times, such as; before eating, after handling animals, and after defecating. The triggering method such as arousing shame, disgust, and fear of getting infected with diseases are the most effective. Further implementation of these methods to trigger the community's HWWS behavior change in other villages with a similar scheme will be potential. ABSTRAK Praktik Cuci Tangan Pakai Sabun (CTPS) untuk mencegah penularan penyakit infeksi Covid-19 masih sangat rendah di Indonesia Timur. Pemicuan untuk perubahan perilaku CTPS pada masyarakat sangat diperlukan agar perilaku CTPS dapat menetap dan berkelanjutan. Kegiatan pengabdian kepada masyarakat ini menggunakan Participatory Rural Appraisal (PRA) yang mengombinasikan 14 metode pemicuan. Kegiatan ini melibatkan 74 responden yang bertempat tinggal di pedesaan Manggarai (NTT) dan Sumbawa (NTB). Keberhasilan kegiatan pengabdian masyarakat ini dilakukan dengan mengukur kebiasaan CTPS sebelum dan sesudah dilakukan pemicuan. Hasil menunjukkan bahwa setelah pemicuan terjadi perubahan signifikan pada praktik CTPS sebelum makan, setelah memegang hewan, dan setelah BAB. Metode pemicuan yang menggugah rasa malu, rasa jijik dan rasa takut sakit merupakan kombinasi metode pemicuan yang paling efektif dalam mengubah perilaku CTPS di lokasi kegiatan. Pemicuan di seluruh pedesaan dengan skema serupa berpotensi dalam mencegah penyebaran virus Covid-19 di NTT dan NTB.
