Pumpkin seeds (Cucurbita spp.) are a byproduct of pumpkin that has great potential to be developed as a functional food ingredient due to their high nutritional content and bioactive compounds. This article aims to examine the valorization (utilization) of pumpkin seeds in various food products and their potential as a functional food. The method used was a narrative literature review through a search of the Google Scholar, ScienceDirect, PubMed, and MDPI databases for the period 2016–2026. The results of the study indicate that pumpkin seeds have been applied in various food products such as cookies, crackers, bread, biscuits, cakes, muffins, and snack bars. The addition of pumpkin seeds generally increases the content of protein, fiber, unsaturated fatty acids, minerals, and bioactive compounds that contribute to antioxidant activity. However, increasing the proportion of pumpkin seeds also affects the physical and sensory characteristics of the product, such as darker color, decreased volume, and changes in texture due to reduced gluten content in the dough. Therefore, formulation optimization is needed to achieve a balance between increasing nutritional value and consumer acceptance. Overall, pumpkin seeds have the potential to be used as an ingredient in the development of functional foods.

Starfruit (Averrhoa bilimbi L.), commonly known in Indonesia as belimbing wuluh, is widely used as a natural acid in traditional cuisine. It is often processed into dried sour starfruit (asam sunti), which can last 1–1.5 years. However, traditional sun-drying methods are inefficient due to weather dependency, long processing times, and inconsistent product quality and color. This study aims to design and develop a tunnel-type starfruit dryer equipped with a blower system and heat control based on the Arduino Mega 2560. The research employs a quantitative method to evaluate tool performance. The dryer is cylindrical and supported by key components, including LPG gas as a heat source, a blower for air circulation, and a drum holder. Drying is conducted in six stages, each lasting 120 minutes, totaling 12 hours to achieve optimal dryness. Temperature monitoring at three points (T1, T2, T3) uses a MAX6675 sensor with a thermocouple connected to the Arduino Mega 2560, while weight measurement is done manually. Results indicate the tool functions effectively. A denser drying chamber and proper blower installation are recommended to ensure even heat distribution and improved drying efficiency for community use.

Mozzarella cheese is traditionally made using rennet, an enzyme derived from the stomach lining of ruminant animals that plays a key role in coagulating milk. While effective, rennet has certain limitations such as its limited availability, relatively high cost, and concerns among vegetarians and certain religious groups regarding its animal origin. As a result, alternative coagulants that are easier to obtain, plant-based, and more environmentally friendly have gained interest. One such natural ingredient is lemon juice, which contains citric acid and can mimic the coagulation effect of rennet. This study aims to explore the effectiveness of lemon juice as a rennet substitute in the production of mozzarella cheese, specifically when applied in a food product like cheese-stuffed potato balls. The research involved organoleptic testing by 30 panelists to evaluate five sensory aspects: color, aroma, taste, texture, and overall acceptance. Several formulations were tested, and the sample containing 20 ml of lemon juice, 2 grams of citric acid, and an additional herb mix (Sample C) was rated the highest in preference across most parameters. The findings suggest that lemon juice is a viable alternative to rennet in mozzarella cheese making, particularly for small-scale or home-based production. It not only delivers acceptable sensory qualities but is also more accessible and affordable. Moreover, using lemon juice supports the development of more sustainable and vegetarian-friendly food options. In conclusion, lemon juice can successfully replace animal-based rennet, making mozzarella cheese production more inclusive, cost-effective, and environmentally conscious.
