Abstract

Abstrak Akar kuning (Fibraurea tinctoria Lour) merupakan tumbuhan khas yang dapat dijumpai di Kalimantan serta biasa dimanfaatkan oleh masyarakat setempat sebagai obat gatal, penyakit kuning dan diare. Salah satu senyawa kimia yang terkandung dalam akar kuning adalah berberin yang berpotensi memiliki khasiat sebagai antidiabetes, antivirus, antibakteri dan antiinflamasi. Penelitian ini bertujuan untuk  mengetahui potensi tumbuhan Akar Kuning (Fibraurea tinctoria Lour.) sebagai antibakteri terhadap bakteri Escherichia coli dan Staphylococcus aureus dengan menggunakan metode disc diffusion. Ekstrak etanol difraksinasi dengan menggunakan pelarut n-heksan dan etilasetat, ekstrak dan fraksi yang telah didapat ditimbang dengan konsentrasi 2,5%, 5% dan 10%. Kontrol positif yang digunakan yaitu amoxicillin dan DMSO sebagai kontrol negatif. Hasil penelitian menunjukkan bahwa ektrak etanol dan fraksi akar kuning (Fibraurea tinctoria Lour.) memiliki potensi untuk menghambat pertumbuhan bakteri. Aktivitas zona hambat terbesar yang terbentuk pada ekstrak etanol yaitu pada konsentrasi 10% dengan diameter zona hambat 9,18 mm terhadap bakteri Escherichia coli dan 12,16 mm terhadap bakteri Staphylococcus aureus sedangkan fraksi batang akar kuning yang memiliki aktivitas antibakteri paling kuat terhadap bakteri Escherichia coli dan Staphylococcus aureus yaitu fraksi sisa. Staphylococcus aureus memiliki sensitifitas lebih tinggi terhadap akar kuning (Fibraurea tinctoria Lour) dari pada bakteri Escherichia coli. Kata kunci  : antibakteri, akar kuning, berberin, Fibraurea tinctoria Lour. Abstract Akar kuning (Fibraurea tinctoria Lour.) is typically plant that can be found in Kalimantan usually used by local people as itch medicine, jaundice and diarrhea. Berberin, one of the chemical compounds contained in the akar kuning, berberin has the potential to act as an anti-diabetic, antiviral, antibacterial, and anti-inflammatory. This study aimed to determine the activity of akar kuning as an antibacterial against Escherichia coli and Staphylococcus aureus using the disc diffusion method. Ethanol extract are fractionated using n-Heksan and Etilasetat solvents, the obtained of extract and fraction are weighed to 2,5%, 5% and 10%. Positive control antibacterial used amoxicillin and DMSO as negative control. The results showed that ethanol extracts and fraction of akar kuning (Fibraurea tinctoria Lour.) are have potential to inhibited bacteria growth. The highest antibacterial activity that showed at 10% concentration of ethanol extract with diameter inhibition is 9,18 mm to Escherichia coli and 12,16 mm to Staphylococcus aureus while the fraction of akar kuning which has the stronger antibacterial activity to Escherichia coli and Staphylococcus aureus is the rest fraction. Staphylococcus aureus were more susceptible to akar kuning (Fibraurea tinctoria Lour.) extract and fraction than Escherichia coli.Keywords:           antibacterial, akar kuning, berberin, Fibraurea tinctoria Lour

Abstract

Breastfeeding is very important for optimal growth and development for babies. One of the efforts that can be done to increase breast milk production is by using traditional ingredients such as katuk extract (Sauropus androgynus (L.) Merr.). This study aims to determine form of the herb, processing method, usage method and the factors behind people using katuk leaves (Sauropus androgynus (L.) Merr.) for breast milk booster in Sumberan Ngestiharjo Kasihan Bantul. The research method used is descriptive qualitative observation. The sampling technique was snowball sampling through observation and in-depth interviews with informants who knew about the use of katuk plants to increase breast milk production in Sumberan Village, then the informants selected respondents to provide additional information. The results showed that the form of katuk leaves (Sauropus androgynus (L.) Merr.) was as a vegetable, brewed, encapsulated and blended to extract the starch. The processing method is cooked as a vegetable, made juice to drink, boiled for fresh vegetables and dried, its use by eating with a frequency of two times a day used during breastfeeding. The factors behind people using katuk leaves to increase breast milk production that is believed katuk leaves can increase breast milk production or breast milk boosters at low prices and easy to obtain. Katuk leaves (Sauropus androgynus (L.) Merr.) to increase breast milk production, which can be consumed as a vegetable by eating it with a frequency of two times a day during breastfeeding. The factors behind people using katuk leaves (Sauropus androgynus (L.) Merr.) that katuk leaves are believed to increase breast milk production.

Abstract

Purpose: This study aims to understand how the cultural elements of Surabaya’s Tugu Pahlawan Monument can be used to introduce basic numeracy in primary school, especially concepts related to plane geometry. The goal is to show that cultural landmarks can offer real and relatable examples for young learners. Method: The research was conducted through a qualitative ethnographic approach. The researcher observed the monument directly, spoke with on-site guides and staff who were familiar with its history, and documented various architectural and visual features. All information gathered from notes, photographs, and short interviews was analyzed using the Miles and Huberman framework to identify patterns that relate to mathematical ideas. Findings: The study found that many parts of the monument display clear geometric forms. These include rectangles, squares, circles, triangles, trapezoids, rhombuses, and even a ten-sided figure. Such shapes appear in the floor patterns, plaques, murals, decorative ornaments, museum structures, and the wheels of military displays. Each of these elements can be directly connected to geometry topics taught in primary classrooms. Significance: The findings highlight the potential of local heritage as a meaningful resource for mathematics education. When students see that the shapes they learn in class appear in a monument tied to their own city’s history, mathematical concepts become easier to grasp and more engaging. This approach supports early numeracy while also helping learners build a stronger connection to their cultural environment.
