Abstract : Beauty is the most beautiful gift that God gives to every woman, how to care for it is also a nature that cannot be separated from the discussion of women, especially in the current millennial era. Beauty for the perception of many women can be relative and difficult to describe, but its meaning can be seen in different perspectives. This study aims to reveal what the meaning of beauty looks like for students of the IAIN Metro Social Studies Department, because based on the author's observations it is found that there are differences in perceptions in terms of interpreting beauty which tend to be seen from appearance so that students try to look beautiful by wearing make-up on campus so that beauty becomes a necessity of social recognition, appreciation and self-actualization. This study was analyzed using the theory of Phenomenology by Alfred Schutz. This study uses a qualitative research method with a phenomenological study approach. The results showed that there were various perceptions of the meaning of beauty for each student, especially Tadris IPS IAIN Metro students in interpreting beauty which tended to be objective in terms of: (1) ideal body shape (2) white and bright skin (3) attractive (outer beauty) rather than subjective meaning as seen from (1) Intellectual Intelligence (2) Emotional Intelligence (3) Spiritual Intelligence (Inner Beauty). The meaning of beauty for students is very diverse, every effort is made to meet certain beauty standards because then they will be more confident, get praise and attention and feel welcomed in a social environment.

Abstract

Limbah sekam padi memiliki potensi besar sebagai bahan baku energi alternatif, namun limbah dari proses pengolahan hasil pertanian yang melimpah ini belum dimanfaatkan secara optimal. Pembakaran langsung sekam padi sering menimbulkan polusi udara, sehingga perlu dilakukan pengolahan yang lebih ramah lingkungan. Salah satu solusinya adalah dengan mengolah sekam padi menjadi briket yang dapat digunakan sebagai sumber energi terbarukan. Artikel ini bertujuan untuk menjelaskan kegiatan pelatihan pembuatan briket berbahan limbah sekam padi sebagai upaya pemanfaatan limbah pertanian sekaligus pemberdayaan masyarakat Desa Sajau Hilir. Metode yang digunakan dalam kegiatan pengabdian ini adalah dengan dilakukannya pendekatan partisipatif yaitu demonstrasi teknik pembuatan briket, serta pendampingan teknis dalam proses produksi. Pelatihan dilakukan secara partisipatif agar terjadi transfer pengetahuan yang efektif kepada masyarakat. Hasil kegiatan menunjukkan bahwa peserta mampu memahami dan mempraktikkan pembuatan briket secara mandiri. Pelatihan ini memberikan dampak positif terhadap peningkatan kesadaran masyarakat mengenai energi alternatif serta potensi pemanfaatan limbah lokal sebagai solusi energi terbarukan di tingkat desa.

Abstract

Dietary pattern and anemia with the occurrence of LBW babies: Indonesian Life Family Survey (IFLS 5)Background: Nutritional problems occur throughout the human life cycle. Maternal, infant, and neonatal mortality rates are critical national growth indicators. The most common cause of death in neonates is babies with low birth weight (LBW). Objective: This study examines the association between diet, anemia, and the incidence of LBW in Indonesia using the Indonesia Family Life Survey (IFLS) wave 5. Methods: This observational study used IFLS 5 secondary data. The study population is women of reproductive age (15-49 years), married, had their last child born alive, and their weight weighed. The independent variables were diet and anemia, while the dependent was LBW. Effect modifiers were age, parity, education, employment, pregnancy complications, consumption of iron tablets, and residence. Results: The total number of respondents was 2,368, with an LBW incidence of 8.7%. The percentage of non-diverse diets is 72.3%, more than diverse diets. There was a significant relationship between diverse dietary patterns and LBW. A less varied diet provides a 1.32 more substantial risk of giving birth to an LBW baby compared to mothers with a diverse diet. However, there was no relationship between anemia and LBW. Further analysis showed two food groups significantly associated with LBW: nuts and meat and fish. Conclusions: A diverse diet lowers the risk of LBW but is not significantly related. Efforts are needed to improve community nutrition through a varied and balanced diet. Social factors related to LBW are mothers' education and employment.

Abstract

Stunting remains a significant child health issue in Indonesia, particularly in Bulungan Regency, with prevalence rates demanding multisectoral interventions. Low socioeconomic factors play a crucial role in stunting incidence due to limited access to nutritious food and healthcare services. This community service aims to optimize rice waste, especially straw and husks, as alternative energy sources to empower local economies and prevent stunting in Sajau Hilir Village. A participatory method was employed through direct education and training involving the PKK women's group. The activities focused on socializing the processing of rice waste into economically valuable products such as rice husk charcoal briquettes and biosensitizers from rice straw. The results showed increased knowledge and skills among community members in converting waste into environmentally friendly and marketable alternative energy products. Utilizing rice waste not only reduces agricultural waste but also opens new economic opportunities sustainably and independently, strengthening family economic resilience and enhancing the ability to meet children's nutritional and healthcare needs. Thus, optimizing rice waste provides a strategic contribution to integrating environmental management and accelerating stunting reduction through local economic empowerment. Recommendations include strengthening community institutions, developing joint business units, and fostering collaboration between universities and local governments.
