Abstract

Phoenix dactylifera L. is widely available on the market and is generally consumed directly, whereas kurma Ajwa dates have a high nutritional content (water 22.8 g; ash 3.43 g; protein 2.91 g; fat 0.47 g; carbohydrates 70%; dietary fiber 6.5–11.5%; and mineral contents of sodium 7.5 mg/100 g, magnesium 150 mg/100 g, calcium 187 mg/100 g, potassium 476.3 mg/100 g, phosphorus 27 mg/100 g, iron 0.15 mg/100 g, and zinc 0.52 mg/100 g), thus presenting potential as a food source to support the prevention of nutritional problems such as stunting. This study aimed to analyze the effect of adding Ajwa date pulp juice as a form of food diversification on the aroma, color, taste, texture, and mineral content of a chocolate beverage. A quantitative method was employed with varying concentrations of Ajwa date pulp addition of 0 g (control), 5 g, 10 g, 15 g, 20 g, and 25 g, coded as M1 to M6, respectively. The characteristics of the chocolate date beverage were evaluated using a hedonic test for aroma, color, taste, and texture, while the nutritional value (minerals) was analyzed by XRF in the sample most preferred by the panelists. Data were statistically analyzed using one-way ANOVA. The results show that the inclusion of Ajwa date pulp juice in the chocolate beverage formulation received positive panelist preferences and tended to increase nutritional value, particularly mineral content; M6 was the most preferred product among 25 panelists, and one of the minerals that increased was calcium, from 41.77 in M1 to 42.172 in M6. However, the addition of Ajwa date pulp juice at different concentrations did not produce statistically significant effects on the hedonic test results (aroma, color, taste, and texture) or on the mineral content of the beverage. Thus, varying levels of Ajwa date pulp juice in chocolate beverages can increase mineral levels, although not significantly in statistical terms, and have potential to be utilized as an alternative form of chocolate beverage diversification based on functional foods.

Abstract

Stunting remains a major public health issue in Indonesia, including in Padang Pariaman Regency, where the prevalence reached 28.3% in 2021 and declined to 19.4% in 2023. Efforts to prevent stunting require a community-based approach that utilizes local resources, one of which is the nipa palm fruit (Nypa fruticans), known for its high nutritional content and potential as functional food. This Community Service Program (PKM) aimed to enhance the knowledge and skills of Posyandu cadres in Nagari Katapiang in processing nipa fruit into nutritious and economically valuable food products. The methods included nutrition education, dissemination of information on nipa fruit potential, and training on appropriate technology for processing nipa into food products such as jam, nuggets, and meatballs. Evaluation was carried out through pre- and post-activity questionnaires. The results showed a significant increase in cadres’ knowledge of nipa’s nutritional content (from 20% to 100%) and health benefits (from 30% to 100%). Perceptions of nipa’s role in stunting prevention also increased from 25% to 95%. Furthermore, practical skills in producing nipa jam improved, where all participants who had never tried before were able to produce processed products after the training. Thus, this PKM activity successfully enhanced the knowledge and practical skills of Posyandu cadres, while demonstrating the potential of nipa fruit as a local food innovation supporting stunting prevention efforts.

Abstract

The reaction rate topic is an abstract chemistry concept closely related to everyday life. However, students often struggle to connect theoretical concepts with real phenomena, resulting in less meaningful learning and limited critical thinking development. Therefore, learning resources grounded in local culture are needed to help students understand chemistry concepts through contextual experiences. The use of an ethnoscience-based module integrated with the GDL model in the reaction rate topic is expected to bridge scientific concepts with local wisdom and enhance students’ critical thinking skills. This study aims to develop and evaluate the validity and practicality of an ethnoscience-based module using the GDL model for the reaction rate topic in Phase F, Grade XI SMA/MA. The research employed a R&D design based on the Plomp model, consisting of the preliminary phase, the development or prototyping phase, and the assessment phase. The study was limited to validity and practicality testing, using a Likert scale questionnaire with a score range of 1–5. The validity assessment results showed an Aiken’s V value ranging from 0.93 to 0.97 across all aspects, indicating high validity. In addition, the practicality level obtained from teachers and students was 95% and 91%, respectively, indicating that the module is practical. Thus, the ethnoscience-based module using the GDL model is valid and practical for supporting learning in the reaction rate topic at the senior high school level. ABSTRAKMateri laju reaksi merupakan topik kimia yang bersifat abstrak namun memiliki keterkaitan erat dengan kehidupan sehari-hari. Peserta didik sering mengalami kesulitan dalam menghubungkan konsep teoritis dengan fenomena nyata sehingga pembelajaran menjadi kurang bermakna dan belum mampu menumbuhkan kemampuan berpikir kritis. Untuk mengatasi hal tersebut, diperlukan sumber belajar yang berorientasi pada budaya lokal agar konsep kimia dapat dipahami melalui pengalaman kontekstual. Penggunaan Modul Bermuatan Etnosains dengan Model GDL pada materi laju reaksi diharapkan dapat mengintegrasikan konsep ilmiah dengan nilai kearifan lokal serta meningkatkan kemampuan berpikir kritis peserta didik. Penelitian ini bertujuan untuk mengembangkan serta menguji validitas dan praktikalitas modul bermuatan etnosains berbasis GDL pada materi laju reaksi fase F kelas XI SMA/MA. Metode penelitian yang digunakan adalah R&D dengan model Plomp, yang terdiri atas preliminary, development or prototyping phase, dan assessment phase. Penelitian ini dibatasi hingga tahap uji validitas dan praktikalitas menggunakan instrumen berupa skala Likert dengan rentang skor 1–5. Hasil analisis validitas modul bermuatan etnosains berbasis GDL pada materi laju reaksi fase F kelas XI SMA/MA menggunakan Aikens’V, dengan nilai Aiken’s V pada setiap aspek berada antara 0,93-0,97 dinyatakan valid serta tingkat kepraktisan guru dan peserta didik masing-masing sebesar 95% dan 91% diyatakan praktis. Dengan demikian modul bermuatan etnosains berbasis GDL pada materi laju reaksi fase F kelas XI SMA/MA telah valid dan praktis digunakan sebagai sumber belajar pada materi laju reaksi di SMA/MA.
