Antifungal resistance has implications for the development of bioactive compounds. Bacillus sp. has been widely studied for the discovery of antifungal volatile compounds. This study aims to explore the antifungal activity of Bacillus sp. HSFI-6 isolated from sea cucumber (Holothuria scabra Fermented Intestine-HSFI) against Malassezia furfur, Candida albicans, and Aspergillus fumigatus. Bacillus sp. HSFI-6 was identified molecularly by 16S rRNA sequencing. Ethyl acetate extract of Bacillus sp. HSFI-6 was produced using media containing starch, yeast, peptone, and its metabolites were profiled using Gas Chromatography-Mass Spectroscopy (GC-MS). A disc diffusion antifungal assay was performed. Bacillus sp. HSFI-6 has 93.47% similarities with Bacillus albus strain MCCC 102146 and moderately inhibit C. albicans (7.00 ± 1.15 mm), A. fumigatus (9.25 ± 0.96 mm). The GC-MS metabolomics analysis showed two antifungal volatile compounds, namely cycloheptasiloxane, tetradecamethyl- and cyclononasiloxane, octadecamethyl-. These results conclude that Bacillus sp. HSFI-6 is suitable for the development of antifungal drugs.

Background: Stunting is a form of chronic malnutrition that affects growth and development during early life. Stunting remains a government priority, with a target to reduce its prevalence to 14%, yet it continues to rank high in the Lamper Tengah Sub-district. This situation is attributed to the lack of family knowledge regarding the risks and long-term impacts of stunting. Therefore, this program aimed to implement stunting risk screening and a booklet-based intervention entitled “Control of Stunting Risk Factors” within the Stunting Community in Lamper Tengah Sub-district, Semarang City. Methods: This community service activity was carried out in Lamper Tengah Village, targeting 10 families with stunted children. The activity methods included preparation, anthropometric measurements, filling out questionnaires on stunting risk factors, and distributing and presenting the booklet “Stunting Risk Factors.” The evaluation stage was carried out by assessing the mothers' level of knowledge about stunting before and after the intervention. Results: Among stunted toddlers, 60% are female, 60% do not receive exclusive breastfeeding, and only 20% practice responsive feeding. After the intervention, the proportion of families with good knowledge levels increased from 80% before the activity to 100% after the activity. Conclusion: The results of the activities show that this community service program is able to increase mothers' knowledge about the risk factors for stunting. Therefore, similar activities need to be continued and expanded to include more participants, accompanied by in-depth counseling and practical guidance on active feeding practices before pregnancy, during pregnancy, and after childbirth to support efforts to reduce stunting rates in Semarang City.

Hipertensi merupakan salah satu penyakit tidak menular dengan prevalensi tinggi dan menjadi faktor risiko utama berbagai penyakit kardiovaskular. Di wilayah kerja Puskesmas Tlogosari Wetan, hipertensi tercatat sebagai penyakit dengan jumlah kasus tertinggi, sehingga diperlukan upaya promotif dan preventif berbasis komunitas. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pengetahuan dan pemahaman masyarakat mengenai hipertensi dan gaya hidup sehat melalui edukasi kesehatan berbasis audiovisual. Metode pelaksanaan berupa edukasi edukatif-partisipatif yang dilaksanakan secara langsung kepada masyarakat dewasa dan lanjut usia dengan hipertensi atau faktor risiko hipertensi di Kelurahan Tlogosari Wetan. Evaluasi dilakukan menggunakan kuesioner pretest dan posttest tingkat pengetahuan hipertensi serta kuesioner gaya hidup. Hasil kegiatan menunjukkan bahwa sebelum intervensi, tingkat pengetahuan responden masih relatif rendah pada aspek kepatuhan minum obat dan penerapan gaya hidup sehat, serta sebagian besar responden memiliki aktivitas fisik, pola makan, dan kebiasaan istirahat yang belum optimal. Setelah intervensi edukasi, terjadi peningkatan pengetahuan yang signifikan pada seluruh materi yang diberikan, yang diperkuat oleh hasil uji Wilcoxon Signed-Rank (p < 0,05). Kegiatan ini menunjukkan bahwa edukasi kesehatan berbasis audiovisual efektif dalam meningkatkan pengetahuan masyarakat mengenai pengelolaan hipertensi. Disarankan agar kegiatan edukasi serupa dapat dilaksanakan secara berkelanjutan oleh puskesmas dengan melibatkan kader kesehatan untuk mendukung pengendalian hipertensi di tingkat komunitas.
