Abstract

Nori is a sheet-shaped snack generally made from Porpyra red seaweed, which is not found in Indonesia. Meanwhile; the binahong plants (Anredera codifolia) are spread through out Indonesia. Binahong leaves are consumed without further processing. Binahong leaves are potential functional food, as they are rich in nutrient. They are high in vitamin A, and vitamin C. They also contain some protein, and fat.  However, binahong leaves have bitter taste and unfavored flavor. In this study, binahong leaves were processed into nori with various concentrations of carrageenan. The concentrations of added carrageenan were 1, 2, and 3 %.  The psychochemical properties of the resulting products were tested by proximate analysis and sensory tests. The result showed that the addition of carrageenan had no significant effect on water, protein, fat, and carbohydrate contents. However, it had significant difference on ash content.  Sensory testing showed that there was no significant difference between treatments in terms of appearance, taste, aroma, texture, and overall assessment.

Abstract

The trend of low-fat consumption is not only limited to main meals, but also to desserts. Ice cream, which is usually made from milk, is replaced by plant-based ingredients that have low fat content but high protein such as soybean juice and sorghum juice. The purpose of this study was to obtain the best plant-based ice cream formulation with the ratio of soybean juice and sorghum juice and the use of xanthan gum as a stabilizer. The method in this study was a completely randomized design with two treatments, namely three ratios of soybean juice and sorghum juice (30:70; 50:50; 70:30) and two concentrations of xanthan gum (0.3% and 0.5%). Physical quality parameters observed were overrun and melting time, chemical quality parameters were proximate and sensory quality parameter which were taste, aroma, texture and overall acceptance. The three best treatments were then analyzed for functional value in the form of total phenolics, flavonoids and antioxidant activity. Statistical analysis used One Way ANOVA with Duncan's difference test. The results showed that the ratio of soybean juice and sorghum juice and the concentration of xanthan gum had a significant effect on physical, chemical and sensory parameters. Ice cream with a ratio of 30:70 and a concentration of 0.3% xanthan gum produced the highest overrun value of 39.71% but the longest melting time was obtained in the treatment of a ratio of 50: 50 and 0.5% xanthan gum concentration of 1005.98 seconds or 16.77 minutes. Based on functional analysis, the highest total phenolics, flavonoids and antioxidant activity were obtained in the ice cream treatment of soybean juice and sorghum juice 50:50 with the addition of xanthan gum as much as 0.5% as a stabilizer.

Abstract

Drono Village, Klaten Regency, Central Java, has the potential as a tempe-producing center. Unfortunately, the skills possessed by tempeh artisans are still limited, and they can only make tempeh withouth further processing diversification. Community Service Activities (PkM) are aimed at PKK members who are tempeh artisans to gain knowledge and skills regarding several types of processed tempeh, namely tempeh katsu and tempeh brownies. The activity method was carried out by providing modules several weeks before the training, distributing questionnaires regarding tempeh processing before the activity, carrying out tempeh processing practices, and assessing participants' understanding and satisfaction by distributing surveys. The activity ended with tasting the processed tempeh products that were produced together. Based on the questionnaire distributed, the participants agreed that they had gained additional knowledge regarding tempeh processing. This activity was also considered beneficial, and all participants were satisfied with their community service activities. The PKK community considers this activity essential and can be repeated with other tempeh-processing food training. They also want to apply the knowledge gained as processed products that can be sold or for family consumption.

Abstract

The global demand for plant-based dairy alternatives is driven by health, environmental, and food allergy or intolerance concerns.  This movement has promoted plant-based yoghurts, which are nutrient-rich and non-dairy. This study examines the physicochemical and sensory characteristics of yogurts made from peanut milk and soy milk, both with and without the presence of filler, a prebiotic polysaccharide. Peanut milk yogurt exhibited a greater fat content of 11.2% wb, protein levels at 6.2% wb, and increased viscosity when compared to soy yogurt. However, soy yogurt exhibited elevated microbial loads (1.5 × 10¹¹ CFU/mL) and protein content when supplemented with inulin, suggesting improved fermentation activity. Both yogurts displayed pH levels appropriate for consumption (4.1–4.6), with peanut milk yogurt demonstrating a marginally higher acidity compared to soy yogurt. The addition of filler had a notable effect on the sensory profile, enhancing texture, taste, and overall acceptability for both peanut milk yogurt and soy yogurt. It is noteworthy that filler-enriched peanut milk yogurt exhibited diminished microbial loads and decreased viscosity, probably as a result of unutilized carbohydrate content and the presence of inhibitory metabolites from fermentation. Proximate analysis indicated that peanut milk yogurt has the potential to function as an effective plant-based yogurt alternative, exhibiting quality comparable to soy yogurt. Organoleptic testing revealed a clear consumer preference for formulations supplemented with inulin, resulting in ratings ranging from "like slightly" to "like extremely." This thorough examination offers significant perspectives on the possibilities of legume-based yogurts in addressing the increasing consumer interest in healthy, plant-derived dairy substitutes

Abstract

Sabun merupakan salah satu produk pembersih yang berperan penting dalam pengendalian mikroorganisme. Penggunaan nanopartikel perak (AgNPs) sebagai agen antibakteri dalam formulasi sabun telah banyak dilaporkan, namun sebagian besar kajian masih berfokus pada sifat intrinsik AgNPs tanpa mempertimbangkan peran sistem sabun sebagai matriks aktif. Artikel ini bertujuan untuk meninjau secara kritis penggunaan AgNPs dalam formulasi sabun antibakteri dengan menekankan aspek formulasi dan relevansi aplikatif. Penulisan review ini menggunakan metode narrative review dengan pendekatan kritis, berdasarkan penelusuran literatur pada basis data Google Scholar, Scopus, dan ScienceDirect terhadap artikel yang dipublikasikan pada rentang tahun 2010–2024. Artikel yang direview diseleksi berdasarkan kriteria inklusi dan eksklusi yang mencakup relevansi terhadap sistem sabun, formulasi berbasis surfaktan, dan evaluasi aktivitas antibakteri, dengan total sekitar 30–40 artikel utama dianalisis secara kualitatif. Hasil tinjauan menunjukkan bahwa kinerja antibakteri AgNPs dalam sabun sangat dipengaruhi oleh interaksinya dengan surfaktan, kondisi pH basa, homogenitas dispersi, serta stabilitas selama penyimpanan dan penggunaan. Review ini mengidentifikasi kesenjangan penelitian utama terkait kurangnya pendekatan formulasi yang rasional, metode uji antibakteri yang aplikatif, serta minimnya kajian keamanan dan dampak lingkungan. Dengan demikian, artikel ini menawarkan kerangka konseptual dan arah riset masa depan untuk pengembangan sabun antibakteri berbasis AgNPs yang lebih efektif, stabil, dan berkelanjutan
