Abstract

Malic acid (2-hydrobutanedioic-acid) is a dicarboxylic acid (carboxylic acid) which is generally found in many apples. Several malic acid derivatives have been synthesized through esterification and amidation reactions, including methyl malate, maleyl oleate and maleyl glutamide. Based on the results of FT-IR analysis of malic acid, it is known that there is an absorption peak at wave number 3448.72 cm¬-1 indicating the presence of an alcohol group and an absorption peak at wave number 1720.50 cm-1 indicating the presence of a carboxylic group. In methyl malate, it is known that in the wave number area of ​​1735.93 cm-1, stretching vibrations of the C=O ester carbonyl group occur. In maleyl oleate, the absorption in the wave area of ​​1743.65 cm-1 is a typical absorption from the stretching vibration of C=O ester. In maleyl glutamide, it is known that there is absorption at the peak wave number of 3425.58 cm-1 which is the stretching vibration of the NH (amide) group. The results of several literatures explain that the malic acid derivative, namely methyl malate, has an HLB value of 11.2 and can be used as an O/W (Oil in Water) emulsifier. The HLB value of maleyl oleate has a value of 4.61 which can be used as a W/O (Water in Oil) emulsifier and for maleyl glutamide the HLB is 14.84 which can be used as an O/W (Oil in Water) emulsifier. Therefore, malic acid derivatives have potential as materials for surfactant synthesis. Keywords: Malic Acid, Esterification and HLB (Hydrophilic Lipophilic Balance).

Abstract

Pengaruh budaya dan sosial dari negara tetangga melemahkan rasa nasionalisme kalangan peserta didik. Tanpa adanya upaya efektif dalam penguatan rasa nasionalisme, ada risiko generasi muda ini akan kehilangan identitas nasionalnya dan kurang memahami pentingnya menjaga keutuhan dan kedaulatan negara. Pentingnya sosialisasi penguatan rasa nasionalisme di daerah perbatasan. Tujuan utama sosialisasi ini untuk meningkatkan kesadaran nasional, menanamkan kebanggaan terhadap identitas nasional serta meningkatkan kesadaran akan pentingnya menjaga kedaulatan negara di kalangan peserta didik SMAN 1 Sajingan. Sosialisasi dilakukan dengan memberikan materi  melalui ceramah, diskusi dan tanya jawab. Melalui diskusi  peserta didik dapat menggali lebih dalam mengenai tantangan dan peluang dalam menjaga identitas nasional serta memperkuat rasa nasionalisme. Pelaksanaan sosialisasi ini dirancang untuk memastikan bahwa peserta didik di SMAN 1 Sajingan memiliki kesadaran yang kuat tentang pentingnya nasionalisme. Capaian hasil pengabdian dari survei menunjukkan 66,7% peserta didik  kategori sangat setuju dan 26,7%  kategori setuju jika penguatan rasa nasionalisme penting dan sekolah memiliki program mendukung peningkatan nasionalisme. Hal tersebut menunjukkan keberhasilan pengabdian ini meningkatkan pemahaman nasionalisme peserta didik di kawasan perbatasan. Selain itu terdapat kesadaran  dampak negatif pengaruh budaya asing. Melalui sosialisasi ini diharapkan peserta didik tumbuh menjadi generasi yang berkomitmen menjaga dan memperjuangkan kedaulatan bangsa di masa depan.

Abstract

The use of natural ingredients in dental care, such as manginang which has become part of the Minang community culture, is considered an alternative dental care that must be created to overcome the negative impacts of dental care made from artificial materials. The core of this study is to change the manginang tradition towards logical verification through screening of bioactive compounds of gambir leaves (Uncaria gambir Roxb.) as antibiofilms against Streptococcus mutans. This study was conducted using an in silico strategy approach with the help of computer programs such as MOE v.09 and Chimera 1.13.1, as well as the Way2Drug site, protein information bank, and protox_ii. This study began with the collection of ligand information from the writing, followed by transformation into 2D and 3D designs. Other antibiofilm actions were decided using the QSAR procedure through the website (http://www.way2drug.com/PASSOnline/predict.php). The selected antibiofilm compounds were then followed by observing their affinity for the receptor (pdb id. 3AIB) using an atomic docking strategy. Finally, the ligand damage profile was observed to anticipate. The results of this study indicate that of the 41 identified gambir leaf compounds, there are 20 compounds that have the potential to have antibiofilm effects with quinnic acid having the highest score (Pa 0.703), while the compound with the strongest affinity for the receptor is chlorogenic acid with an affinity score (Gbinding) of -16.03 kcal/mol and an average of low toxicity (level IV-VI). However, of the 20 bioactive compounds of gambir leaves, only 5 compounds are predicted to have the same potential as the -maltose control.

Abstract

Objective: This study aimed to evaluate the effect of gamal (Gliricidia sepium) leaf silage on the growth performance of local male goats. The research focused on key growth parameters, including daily feed consumption, daily body weight gain (PBBH), feed conversion, and feed efficiency. Method: The experiment was conducted using a randomized block design (RAK) with four treatments and four replications. The treatments included (P0) control with elephant grass without gamal leaves, (P1) 20% gamal leaf silage and 80% elephant grass, (P2) 50% gamal leaf silage and 50% elephant grass, and (P3) 100% gamal leaf silage. The goats were monitored over four weeks to assess their growth response to different feeding compositions. Results: The findings revealed a significant effect of gamal leaf silage on the growth performance of local male goats. The inclusion of gamal leaf silage improved daily body weight gain, feed conversion, and feed efficiency. Higher proportions of gamal leaf silage in the diet resulted in better growth performance compared to the control group. Novelty: This study highlights the potential of gamal leaf silage as an alternative, cost-effective feed source for ruminants. The results contribute to the understanding of utilizing non-conventional feed ingredients to reduce feed costs while maintaining livestock productivity.

Abstract

Research about the isolation of chemical active compounds antioxidants from ethyl acetate fraction of betel leaf forest (Piper aduncum L.) have been done. This research aimed to determine the type of secondary metabolites that contained in ethyl acetate fraction and the value of antioxidant activity as well as the structure that contained in ethyl acetate fraction. The test results of phytochemical showed that the secondary metabolites in ethanol extract are alkaloids, steroids and triterpenoids. The inhibitory concentration 50% (IC50) value that shown in the fraction Piper aduncum ethyl acetate-4-3 (PAEA-4-3) is 132.84 ppm. Fraction of PAEA-4-3 that have high levels of antioxidant activity was analyzed using a spectrophotometer Ultra Violet-Visible (UV-Vis), Infrared Fourier-Transform (FTIR) and Nuclear Magnetic Resonance (NMR) proton and carbon. The result analysis of PAEA-4-3 isolates showed the compound as 2,3-dimethoxy-metilanaoksi-benzene.
