Abstract

This research aimed to examine the antibacterial activity of lotus leaf (Nelumbo nucifera) extract as a basis for herbal tea production. Lotus leaf was chosen as the herbal tea ingredient due to its abundant availability in South Kalimantan and its believed beneficial phytochemical content for health. The research process involved several stages including lotus leaf herbal tea processing, multi-stage maceration extraction using hexane, ethyl acetate, and ethanol solvents, and testing the extract's ability against Escherichia coli bacteria. The research design employed a 2-factor complete randomized design, with the first factor being the extract concentration and the second being the solvent type. Data analysis was conducted using Two-Way ANOVA in IBM SPSS 25. The results revealed that ethanol solvent produced the highest concentration extract with a yield of 10.86%, while hexane solvent yielded the lowest at 1.64%. Subsequent antibacterial activity testing was carried out using direct contact method with lotus leaf extract concentrations of 0.5%, 1%, and 1.5% in all three solvents. The findings indicated that 0.5% and 1% concentration extracts inhibited Escherichia coli growth across all solvents, whereas the 1.5% extract concentration in ethanol was capable of killing Escherichia coli bacteria. It was concluded that lotus leaf extract holds potential as an antibacterial agent, with higher extract concentrations showing greater efficacy in inhibiting bacterial growth. The 1.5% concentration (45 μl) exhibited the most effective results in killing Escherichia coli, underscoring the potential of Nelumbo nucifera lotus leaf in the development of antibacterial herbal products.

Abstract

The children's tahfidz house is a conscious effort to eradicate the phenomenon of Al-Qur'an illiteracy that occurs in society due to modernization that is currently occurring. In the tahfidz house learning process, problems that arise are related to ineffective and efficient learning methods due to limited space to accommodate tahfidz house activities and events. Children who study in a space that is not conducive will hamper their learning process and cause children to be distracted by conditions outside of learning. So that children's understanding in listening to the teacher's explanation will decrease and end up with children who cannot understand the lesson. The result of the design is a design concept related to tahfidz home learning methods by paying attention to the child's character through an architectural approach to make it easier for children to learn the Koran. The method adopted is to make children familiar with the learning material, as well as developing children's interests, skills, attitudes and behavior.

Abstract

The peatlands have the potential to support food security efforts. However, there is have constraints on soil fertility, especially the P nutrients availability. The biotechnology approach, the application of ameliorant (biochar-compost carrier medium (biocom)) enriched with phosphate solubilizing fungi (PSF) and coal fly ash (CFA), was expected to increase the P-availability in peat soils. The research aimed to study the application of biocom enriched with PSF and CFA to increase soil P-availability and plant P-uptake. The study was conducted using peat soil media with the formulation of CFA and biocom enriched with PSF and CFA as treatments. The treatment effect was observed through soil P available and plant P uptake of maize. The results showed PSF application was inconsistent in improving P available in peat soils in Kalimantan. In Central Kalimantan, Biocom + PSF was able to increase P available in peat soils by up to 406.18% (A. oryzae-Tb7) and 353.44% (N. fischeri-Tm8). However, in South Kalimantan P available in peat soil was only 8.04% (A. oryzae-Tb7) and 12.86% (N. fischeri-Tm8). The CFA+ (biocom+PSF) formulation increased P available in Central Kalimantan peat soils, but it was different from South Kalimantan peat soils. The application of biocom+PSF and CFA has not been able to increase the P uptake of maize plant in peatlands of South Kalimantan.

Abstract

Pembelajaran matematika tidak hanya menuntut penguasaan konsep, tetapi juga pemaknaan proses berpikir dalam konteks kehidupan nyata, termasuk budaya lokal. Penelitian ini bertujuan mengidentifikasi dan menganalisis konsep penjumlahan dan aritmetika modulo dalam praktik adat babilangan serta menjelaskan langkah-langkah pelaksanaannya di masyarakat Tapin. Penelitian menggunakan pendekatan kualitatif eksploratif. Data dikumpulkan melalui wawancara semi-terstruktur dan dokumentasi terhadap tiga informan dari desa berbeda yang memahami Adat Babilangan. Analisis data menggunakan model Miles dan Huberman yang meliputi reduksi data, penyajian data, dan penarikan kesimpulan.Hasil penelitian menunjukkan bahwa Adat Babilangan berakar pada praktik hisab berbasis aksara hijaiyah yang diwariskan secara turun-temurun. Konsep matematis yang ditemukan meliputi penjumlahan bilangan bulat serta aritmetika modulo multibasis, seperti modulo 12 untuk menentukan sifat individu serta modulo 3, 5, dan 7 dalam penentuan nasib pernikahan melalui perhitungan nilai aksara. Meskipun terdapat variasi nilai aksara dan perbedaan penafsiran antar narasumber, struktur perhitungan tetap konsisten, yaitu penjumlahan yang diikuti pembagian bersisa. Temuan ini menunjukkan bahwa Adat Babilangan merupakan bentuk matematika informal yang berpotensi menjadi konteks pembelajaran yang mengaitkan konsep matematika formal dengan budaya lokal. Kata kunci: Adat Babilangan, Etnomatematika, Modulo, Penjumlahan Abstract: Mathematics learning requires not only conceptual mastery but also meaningful understanding of thinking processes in real-life contexts, including local cultural practices. This study aims to identify and analyze the concepts of addition and modular arithmetic embedded in the Adat Babilangan tradition and to systematically describe the procedures used in its implementation within the Tapin community. The study employed an exploratory qualitative approach. Data were collected through semi-structured interviews and documentation involving three participants from different villages who are knowledgeable about Adat Babilangan. Data analysis followed the Miles and Huberman model, including data reduction, data display, and conclusion drawing. The findings indicate that Adat Babilangan is rooted in a traditional calculation system based on the Arabic (Hijaiyah) script, transmitted across generations. The identified mathematical concepts include integer addition and multi-base modular arithmetic, such as modulo 12 for determining individual characteristics, and modulo 3, 5, and 7 for determining marital compatibility through calculations based on the numerical values of Hijaiyah letters. Despite variations in letter values and differences in interpretation among informants, the underlying computational structure remains consistent, involving addition followed by division with remainders. These findings suggest that Adat Babilangan represents a form of informal mathematics with potential as a culturally relevant context for connecting formal mathematical concepts to local traditions. Keywords: Adat Babilangan, Addtion, Etnomatematics, Modular
