Abstract

Background: Dietary antioxidants are essential to prevent free radical-induced cell damage and maintain the body’s physiological functions. Sembung leaves are rich in polyphenols, which are known to have substantial antioxidant activities. The antioxidant efficacy of Sembung leaves can be enhanced by nanoparticle size. Objectives: To examine the enhancement of antioxidant activity of Sembung leaf (Blumea balsamifera L.) extract modified into nanoparticles. Methods: The extract used was an ethyl acetate fraction extract. The fresh leaves of Sembung ware macerated in 96% ethanol for 24 hours. Ethanol, n-hexan, and ethyl acetate solvents were used to fractionate the ethanolic extract. The extract of the ethyl acetate fraction was modified into nanoparticles through the ionic gelation method. The nanoparticles comprised three formulations, F1 (0.25% chitosan and 10 ml NaTPP solution), F2 (0.50% chitosan and 20 ml NaTPP solution), and F3 (0.75% chitosan and 30 ml NaTPP solution). The antioxidant activity was assessed by lipid peroxidation using ferric thiocyanate (FTC) followed by the thiobarbiturat (TBA) method. A Spectrophotometer UV-Vis was used to analyse the % inhibition values of the samples. Results: The antioxidant activity assay on the sample of ethyl acetate fraction using the FTC method showed 31.25% inhibition, and using the TBA method indicated 17.34% inhibition. Meanwhile, the % inhibition was 23.77% and 40.43% in the nanoparticle sample with the FTC and TBA methods, respectively. Conclusions: This study revealed that nanoparticles of Sembung leaves  can increase antioxidant activities. These findings offer potential applications in the development of existing antioxidant products.

Abstract

Background: Goat milk offers more superior health benefits than cow milk, while mung beans possess high nutrient contents and promote probiotic growth. Enhancing goat milk yogurt with mung bean extract through fermentation can improve product quality and consumer acceptance by mitigating the off-flavors. Objectives: To determine the physicochemical, microbiological, and sensory characteristics of goat milk yogurt with mung bean extract enrichment. Methods: A Completely Randomized Design (CRD) was employed with four different formulation ratios of goat milk and mung bean extract at 100%:0%, 85%:15%, 70%:30%, and 55%:45%. Physicochemical properties, such as pH, acidity, ash, total solids, protein, fat, and total sugar were analyzed. on the total amount of lactic acid bacteria (LAB) was counted as microbiological analysis component. Sensory evaluations were conducted using hedonic and hedonic quality tests. All parameters were analyzed using a one-way ANOVA, and the best formulation ratio was determined using the De Garmo method. Results: pH of the product was 3.96 to 4.12, as acidity increased along with a higher mung bean extract. Ash, protein, fat, and total solids content varied moderately across samples, influencing the nutritional profiles of the yogurt. The amount of LAB peaked at 8.95 Log CFU/ml in the 85%:15% formulation ratio. Sensory evaluations showed the highest score of texture and overall assessments in the 85%:15% formulation ratio by achieving optimal tanginess, sweetness, and texture balance. Conclusions: Enriching goat milk yogurt with mung bean extract can significantly influence the physicochemical, microbiological, and sensory characteristics. The formulation of 85% goat milk and 15% mung bean extract provides the more enhanced nutritional value, probiotic potential, and consumer acceptance.

Abstract

Non-communicable diseases (NCDs) are a growing public health concern globally and in Indonesia, strongly associated with poor nutrition and unhealthy lifestyles. Schools are effective platforms for health promotion through sustainable nutrition education. The program was conducted at SMA Swasta Utama, Medan (March–July 2025) with 10 teachers and 36 students, involving preparatory coordination, development of educational tools, and delivery of nutrition education through lectures and multimedia discussions. Knowledge improvement was assessed using pretest–posttest with the Wilcoxon paired test, while teachers also received training in anthropometry, blood pressure monitoring, biochemical testing, and the Productivity Risk Self-Assessment Tool (PRISAT), supported by the provision of self-monitoring equipment. Results showed significant knowledge improvements in both groups, with clear shifts from poor to moderate and good categories (p<0.05). Teachers achieved greater gains than students, reflecting their role as facilitators and role models in health education. PRISAT screening revealed most teachers were low risk, though some were categorized as high risk, underscoring the importance of early detection. This program demonstrates the effectiveness of integrating nutrition education and health monitoring to strengthen school-based NCD prevention.

Abstract

Minuman fermentasi kulit buah nanas (tepache) merupakan salah satu produk pangan probiotik yang memiliki potensi besar untuk dikembangkan secara komersial. produk minuman tepache yang akan dikembangkan secara komersil wajib mengikuti persyaratan Peraturan BPOM Nomor 31 Tahun 2018 tentang Label Pangan Olahan yakni pencantuman batas kadaluwarsa pada label kemasan. Penelitian tentang tepache juga telah banyak dilakukan yang hanya berbasis pada formulasi dan karakteristik fisikokimia produk. Sementara, kajian mengenai pendugaan umur simpan (shelf- life) tepache belum mendapatkan perhatian, sehingga aspek krusial ini perlu diketahui sebagai upaya keberlanjutan dalam pengembangan produk secara komersil. Penelitian ini bertujuan untuk mengetahui masa simpan produk minuman tepache dengan berbagai kemasan dan suhu penyimpanan. Penelitian ini akan dilakukan dalam 3 tahapan. Tahap pertama yaitu pembuatan produk tepache menggunakan formulasi terbaik hasil dari penelitian sebelumnya pada tahun 2024. Tahap kedua yaitu melakukan pengemasan produk (botol kaca dan botol PET (Polyethylene Terephthalate)) dan disimpan pada suhu 5-8oC, 25-27oC, dan 45oC selama 0-14 hari. Selanjutnya, dilakukan pengujian mutu sensori dan fisikokimia pada setiap produk. Uji sensori meliputi warna, aroma, rasa, kekentalan, mouthfeel yang dilakukan pada 5 panelis terlatih. Pengujian organoleptik menggunakan metode hedonik menggunakan skala 1 sampai 5. Parameter mutu fisikokimia yang akan diamati adalah nilai pH dan viskositas. Tahap ketiga melakukan pendugaan umur simpan dengan menyimpan produk pada kemasan dan suhu berbeda. Pendugaan Umur Simpan dilakukan dengan metode ASLT (Accelerated Shelf Life Test) Model Arrhenius. Minuman tepache memiliki umur simpan 17,67 hari berdasarkan parameter warna, 17,67 hari berdasarkan parameter aroma, 12,43 hari berdasarkan parameter rasa, 15.95 hari berdasarkan parameter mouthfeel/kekentalan, dan 40,59 hari berdasarkan parameter pHKata kunci: Umur Simpan, Tepache, Kemasan, Arrhenius.@font-face {font-family:"Cambria Math"; panose-1:2 4 5 3 5 4 6 3 2 4; mso-font-charset:0; mso-generic-font-family:roman; mso-font-pitch:variable; mso-font-signature:-536870145 1107305727 0 0 415 0;}@font-face {font-family:Calibri; panose-1:2 15 5 2 2 2 4 3 2 4; mso-font-charset:0; mso-generic-font-family:swiss; mso-font-pitch:variable; mso-font-signature:-536859905 -1073732485 9 0 511 0;}p.MsoNormal, li.MsoNormal, div.MsoNormal {mso-style-unhide:no; mso-style-qformat:yes; mso-style-parent:""; margin-top:0cm; margin-right:0cm; margin-bottom:10.0pt; margin-left:0cm; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri",sans-serif; mso-fareast-font-family:Calibri; mso-bidi-font-family:"Times New Roman"; mso-ansi-language:EN-GB;}p.E-JOURNALAbstractBody, li.E-JOURNALAbstractBody, div.E-JOURNALAbstractBody {mso-style-name:E-JOURNAL_AbstractBody; mso-style-unhide:no; mso-style-qformat:yes; margin:0cm; text-align:justify; text-indent:1.0cm; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Times New Roman",serif; mso-fareast-font-family:"Times New Roman"; mso-ansi-language:IN;}p.StyleE-JournalKeywordsNotItalic, li.StyleE-JournalKeywordsNotItalic, div.StyleE-JournalKeywordsNotItalic {mso-style-name:"Style E-Journal_Keywords + Not Italic"; mso-style-unhide:no; margin-top:6.0pt; margin-right:0cm; margin-bottom:6.0pt; margin-left:0cm; text-align:justify; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Times New Roman",serif; mso-fareast-font-family:"Times New Roman"; mso-ansi-language:IN;}.MsoChpDefault {mso-style-type:export-only; mso-default-props:yes; font-size:10.0pt; mso-ansi-font-size:10.0pt; mso-bidi-font-size:10.0pt; font-family:"Calibri",sans-serif; mso-ascii-font-family:Calibri; mso-fareast-font-family:Calibri; mso-hansi-font-family:Calibri; mso-font-kerning:0pt; mso-ligatures:none; mso-ansi-language:IN; mso-fareast-language:IN;}div.WordSection1 {page:WordSection1;}

Abstract

Background: The commercial development of tepache beverages requires systematic mapping of sensory attributes, such as the Check-All-That-Apply (CATA) method, to ensure alignment with consumer perceptions. However, integration of emotional responses during sensory evaluation remains relatively underexplored. Emotional profiling offers complementary insights alongside conventional sensory acceptance data, offering a more holistic understanding of consumer responses to the product. Objectives: This study aimed to identify the sensory profile of tepache beverages using the CATA method and to determine emotional profiling through the Emotional Sensory Mapping (ESM). Methods: This study was conducted in two stages: Sample preparation and sensory testing. The materials used included three formulations of tepache beverage (A, B, C), mineral water, and crackers. The tools utilized were stationery, questionnaires, cups, and the XLSTAT 2020 software. Results: Correspondence Analysis showed that product A is closely correlated with acidity, product code B with citrate, and product code C with sparkle. Emotional profiling in Cochran’s Q test revealed significant difference at 5% level, with relaxing, energy, plain, and satisfied influencing consumer perceptions. Conclusions The correlation between the mouthfeel sensory attributes and preference for the tepache beverage samples was found in sweetness and richness, while the sensory attributes at swallow were lightness and richness. Emotional profile mapping indicates that consumers prefer relaxing emotional response observed in product C.
