Abstract

Helicobacter pylori termasuk patogen opportunistik yang memiliki ciri berupa Gram negatif, flagela lopotrikus, tidak berkapsul, dan urease positif. Bakteri ini mampu menyebabkan gastritis, tukak lambung, dan kanker lambung. Penelitian ini bertujuan untuk mengetahui aktivitas nanoemulsi minyak lengkuas (Alpinia galanga L. Willd) dalam menghambat pertumbuhan bakteri Helicobacter pylori. Nanoemulsi minyak lengkuas dibuat dengan bantuan magnetic stirer dan ultrasonikator kemudian dianalisa ukurannya dengan Particle Size Analyzer. Uji aktivitas terhadap H. pylori dilakukan dengan metode difusi sumuran. Hasil penelitian menunjukkan bahwa nanoemulsi minyak lengkuas 1% (ukuran droplet 19.9 nm) mampu menghambat bakteri H.pylori dengan zona hambat sebesar 9,5 mm. Nanoemulsi minyak lengkuas dapat digunakan sebagai kandidat pengobatan infeksi lambung sehingga mampu mencegah karsinoma lambung.

Abstract

The problem of stunting is still a health problem that is a major concern for the Sidoarjo Regency government. While the stunting rate at the national level and East Java will decrease in 2022, Sidoarjo Regency shows an increase. In efforts to prevent and overcome stunting, the Sidoarjo Regency government has focused efforts in several villages spread across a number of sub-districts. Furthermore, the aim of this community service activity is to provide education about stunting and its prevention. This community empowerment activity consists of outreach activities to high school students as stunting ambassadors, and training on nutritious food processing attended by PKK cadres in Sidoarjo which is packaged in the Stop Stunting program. The activity method is carried out through coordination with the government, entrepreneurs and educational institutions, counseling of PKK cadres and high school student representatives, as well as training in processing nutritious food ingredients. This activity was attended by 50 students and counseling guidance teachers, as well as 100 PKK cadre mothers in the Sidoarjo area. Overall, the activities in the Stop Stunting program can be implemented well thanks to the cooperation of all related parties. The community service activities that have been carried out are able to increase participants' knowledge about stunting as well as efforts to prevent it, including increasing the ability of PKK cadres to process food ingredients..

Abstract

Pembelajaran sains yang efektif memerlukan metode yang mampu mendorong siswa untuk memahami konsep melalui pengalaman langsung. Di Kabupaten Humbang Hasundutan, Provinsi Sumatera Utara, keterbatasan fasilitas dan akses pendidikan menjadi salah satu hambatan dalam penerapan pembelajaran sains yang optimal. Program pengabdian kepada masyarakat ini bertujuan untuk meningkatkan kualitas pembelajaran IPA bagi siswa sekolah dasar melalui pendekatan Pembelajaran Sains Berbasis Eksperimen menggunakan alat sederhana dan sumber daya lokal. Berdasarkan observasi selama proses belajar mengajar, seluruh siswa terlibat aktif dalam percobaan, interaktif, serta mampu mengembangkan kemampuan berpikir kritis dan rasional. Selain memberikan pengalaman eksperimen langsung kepada siswa kelas 4–6, program ini juga melibatkan pelatihan guru serta penyediaan modul pembelajaran interaktif yang mudah diterapkan secara berkelanjutan. Kegiatan ini dapat meningkatkan literasi sains, minat belajar, dan pemahaman konsep dasar IPA di sekolah-sekolah dasar di Kabupaten Humbang Hasundutan.
