Abstract

Instant noodles are a food product that the public highly favors because of their diverse taste, easy presentation, and economical price. Instant noodles cannot be considered whole food because they do not meet the needs of balanced nutrition for the body. Purslane flour (Portulaca oleracea L.) contains macronutrients and micronutrients in the form of carbohydrates, protein, dopamine, potassium salts, tannins, saponins, vitamin A (β-carotene), Vitamin B, Vitamin C, nicotinic acid and natural antioxidants related to fatty acids omega 3 by 44.29%. This study contributed to compare the effectiveness of the substitution of Purslane flour and glucomannan powder on organoleptic test instant noodles. This study was an experiment with a completely randomized design of two-factorial with six treatments including the formulation of purslane flour 25%, 30%, and 35%, while glucomannan formulation of 5%, 10%, 15% with two temperature treatments, 50 °C, and 60 °C. We conducted an organoleptic test with statistical analysis t-test and descriptive. The substitution of purslane flour and glucomannan in instant noodles gave the best organoleptic characteristics in the K2S2 treatment (the formulation of 60% wheat flour, 30% purslane flour, and 10% glucomannan at a drying temperature of 60 °C) with proximate analysis content of 12.26% moisture, 5.53% ash, 5.13% fat, 13.91% protein, and 63.14% carbohydrates.

Abstract

Original "SuleMu" soy milk currently has limited shelf life without refrigeration. Therefore, it is crucial to assist partners in enhancing product competitiveness and diversification. The primary objectives of this community engagement activity were to improve SuleMu's marketability through the addition of new flavors and the provision of nutritional value analysis, as well as to enhance product quality by developing derivative products such as soyghurt and frozen yogurt. The activity stages included: (1) mentoring for the diversification of SuleMu derivative products, (2) nutritional value analysis of derivative products, (3) designing product labels compliant with standards, and (4) conducting a market survey on consumer preferences for SuleMu derivative products. Results indicate that SuleMu is now available in new flavors: melon, chocolate, and strawberry. The nutritional content per 100 grams is 3.4–3.5 grams of soluble protein, 3.3–3.7 grams of fat, 5–5.7 grams of reducing sugars, 2.6–3.6 grams of crude fiber, and approximately 39–40 mg of calcium. SuleMu production increased from 5 kg of soybeans to 6 kg per day. Furthermore, consumers showed high interest in the "Soyoghurt" frozen yogurt derivative product, with 42.4% being very interested and positive evaluations regarding taste (36.1%) and affordable price (29.2%). Overall, this community engagement activity successfully increased SuleMu's production by 17%, and soyghurt demonstrates significant potential for development as a highly competitive new innovation.

Abstract

This research aims to develop a web-based mobile plant-tagging application that connects local plant species to scientific information through QR codes, which emphasizes contextual, technology-assisted learning grounded in local potential. The resulting educational media, titled Pelurutaloka (an acronym for Pembelajaran Luar Ruang Tanaman Lokal, or Outdoor Learning of Local Plants), is specifically designed to be pedagogically relevant and to serve as a foundation for future studies in local natural resources.This study adopts a Research and Development (R&D) methodology using the 4D model (Define, Design, Develop, Disseminate), with development limited to the evaluation/revision stage. The evaluation phase employed a 14-item Likert-scale questionnaire, which demonstrated high levels of validity and reliability based on expert review and Rasch model analysis (reliability = 0.72). Further Rasch analysis revealed a unidimensionality value of 40.2%, exceeding the acceptable threshold of 20%, indicating that the instrument effectively measured a single construct. The primary contribution of this research lies in the creation of a web-based, mobile-accessible biology learning media designed for outdoor contexts, offering an engaging, technology-enhanced learning experience that promotes student activity and interaction with the environment. This study recommends broader dissemination of the Pelurutaloka platform and its implementation in outdoor biology education, particularly through collaborative, active learning models such as problem-based learning (PBL) and project-based learning (PjBL).
