Abstract

Oyster mushroom is one of the non-cholesterol food ingredients that have high nutrition and high demand by the public. In addition, oyster mushroom has a much cheaper price than chicken and beef. In the cultivation of oyster mushrooms, temperature and humidity are important factors in the success of cultivation, the optimum temperature for the growth of oyster mushrooms is 16-25°C and the ideal humidity required is 80%-90%. To maintain the temperature and humidity is to do watering or misting. Currently, there are still many farmers who use conventional watering systems that are not practical. Therefore, during the dry season, the productivity of oyster mushrooms tends to decrease due to hot weather conditions and intense watering needs to be done. Based on this, it is necessary to develop an automatic and efficient mushroom watering tool. The research method used is Research and Development (RD). The result achieved is the design of an automatic mushroom sprinkler based on temperature and humidity control. This automatic mushroom sprinkler has a blower component, piezoelectric, ATMega 16 microcontroller, DHT11 temperature sensor, and internet of things (IoT) features. The conclusion of this research is the creation of an automatic mushroom sprinkler that is efficient and easy to use. In addition, the results of the implementation of this tool in the cultivation area can increase the productivity of oyster mushrooms by 34.51%.

Abstract

Indonesia is a maritime country and many people work as traditional fishermen. Traditional fishermen generally use thermos filled with wet ice, ice boxes, or ice blocks to maintain the freshness of fish. The temperature obtained is still insufficient to maintain the fish’s quality and freshness. Furthermore, some existing technologies are expensive and use fossil fuels. Researchers designed and manufactured a cool box that utilizes solar energy to store fish. The experimental research method was conducted by testing the performance of the cool box device at four different locations. The results showed that the solar panel produced an average of 2,527.2 W of energy in a day, which can power the cool box device for 10 hours. To maintain the fish’s freshness with the reference temperature of 0 °C-5 °C, the device uses temperature control to prevent the fish from freezing, which damages its structure. The temperature control also helps the tool save energy, allowing it to last 170 minutes longer than without using the temperature control feature.

Abstract

Indonesia remains highly dependent on wheat imports, reaching 7.39 million tons annually, threatening national food security. Additionally, this heavy reliance on wheat imports can jeopardize economic stability, as wheat prices are controlled by producing countries. Therefore, it is essential to find local food alternatives that can replace wheat, one of which is purple sweet potato (Ipomoea batatas Blackie), which is widely available in Indonesia. This study explores the potential of purple sweet potato as an alternative raw ingredient in pizza production to reduce dependence on wheat imports. The research employs an experimental method with qualitative and quantitative analysis. Pizza was prepared by partially substituting wheat flour with purple sweet potato, followed by an organoleptic test conducted by 20 panellists to evaluate taste, texture, aroma, color, and presentation. The results indicate that purple sweet potato pizza has a balanced nutritional composition, containing 250 kcal of energy, 40g of carbohydrates, 6g of protein, 8g of fat, 3g of fiber, 500IU of vitamin A, and 10mg of vitamin C per 100g. Market response to this product was highly positive, with an average overall score of 4.38 out of 5, indicating good consumer acceptance. The substitution of purple sweet potato in pizza not only enhances nutritional value but also offers a more sustainable local food alternative. This study concludes that this innovation has the potential to be developed within the food industry, support food diversification, and reduce reliance on imported wheat flour.

Abstract

Limited food availability poses a significant challenge in keeping pace with rapid population growth. The impact is seen in the 30.8% of children under five in Indonesia who are stunted, signaling a serious nutritional problem. To solve this problem, it is important to find solutions that are healthy and affordable for the community. One of Indonesia's popular, affordable and versatile specialties is tempeh. However, the high consumption of tempeh poses a problem of domestic soybean availability for producers, prompting the search for alternative ingredients in the manufacture of tempeh. Lotus Fruit Seeds (Nymphaea sp.) were identified as a potential substitute for soybeans in making tempeh. The 71.06% carbohydrate and 10.86% protein content in these seeds offers an attractive alternative. This study attempted to use lotus fruit seeds as a raw material for tempeh, while gauging public responses to this product in terms of color, price, taste and aroma. Based on the results of the proximate analysis, the best experiment for processing tempeh from lotus seeds is boiling twice for 15 minutes each, because it can produce a high amount of protein, 37.38%. This study tried to use lotus fruit seeds as raw material for tempeh, while measuring public response to this product in terms of color, price, taste, and aroma. The results showed that tempeh from lotus fruit seeds has similar characteristics to soybean tempeh, the process of making tempeh from lotus seeds is relatively similar to soybean tempeh, although further research is needed to optimize the use of lotus. This has the potential to increase the economic value of lotus into a more meaningful alternative in food fulfillment in Indonesia.
