Abstract

The egg incubator is an egg incubator equipped with a heater with a special construction so that the heat in the box is not wasted. This study aims to determine the heat transfer in an automatic egg incubator with incubator dimensions of 0.38 × 0.35 × 0.45 m. The research was conducted by collecting data directly to obtain heat transfer values in automatic egg incubators with a heat source from a light bulb. A digital thermometer was used to measure the temperature of the egg incubator. The incubator temperature was maintained at a maximum temperature of 39°C. Radiation heat transfer that occured in an egg incubator with a surface area of 0.92 m² which was coated with aluminum foil with a material emissivity value of 0.07 and an egg incubator temperature of 39°C (312 K) was 34.6 Watt. The conduction heat transfer that occured on the wall of the egg incubator with the thermal conductivity value of aluminum foil, namely k = 0.034 W/mK, was 34.78 Watt. The results of the study by setting the temperature of the incubator room to a maximum of 39oC obtained a hatching success rate with a hatchability of 75%.

Abstract

In Indonesia, the production of water spinach increased by 9,24% from the last year, which was reasonable because water spinach was one of the most sought-after and popular types of vegetables. The farmers have exposure risk factors of work-related musculoskeletal disorders (MSDs) owing to poor watering of plant workstations using manual methods. This journal aims to explore the application of computer-aided ergonomic analysis and digital human modeling techniques in optimizing the workstations of farmers in water spinach plantations. This paper compares ergonomic scores for body posture farmers before and after improvement. Improvement was done by replacing the manual ball valve with motor operated valve (MOV), controlled (opens and closes) by farmers’ phones. Before and after improvement, body posture farmers are converted to digital human modeling and analyzed by CATIA and RULA analysis tools. The result of this paper comparing before and after improvement results in a percentage reduction in RULA Scores of 75% from a 4 to 1 value.

Abstract

The high market demand for water spinach can be a great opportunity to improve the local community's economy. The distribution of water to the kale plants must be done regularly and evenly, while the watering activities of the kale plants by the farmers are still done manually by carrying 20 liters of water. The problem so far is that the farmers water the kale plants by repeatedly carrying water on their backs. so it is necessary to have a control and monitoring system to make it easier for farmers to water the water spinach plants using an internet of thngs system to open and close with sensors that are sent to the database and then displayed in the form of tables and graphs. The results show that the control and monitoring of water sprinkling was successful according to the programmed water discharge.
