In today's digital era, most people use smartphones for various purposes. In the laboratory field,  as an innovation in laboratory examinations, and as a form of community service to promote healthy living and change people's lifestyles, medical laboratory technicians play a role in creating medical record applications. The development of this application is based on the fact that patients often forget about the examinations they have undergone, making it difficult to accurately record medical history. The examinations conducted on patients are a benchmark for lifestyle patterns that should be carefully considered by patients. This attention begins with the periodic recording of health history, which should be done to anticipate spikes or abnormalities in the body's condition. The application system, created through a semi-automatic method for recording and reminding examinations, is able to minimize errors or inaccuracies in the examination results in the history, thus facilitating self-control of both lifestyle, examinations, and health. Medical record application software can provide health data from previous laboratory examinations and can provide reminders for the next scheduled examination."

Competition in the industrial world after the impact of Covid-19 has become fierce competition. Many companies choose to increase effectiveness and efficiency by implementing digitalization in production and sales activities. PT. Megarhizo Ega Persada is a company that is developing, a company whose main production is liquid organic fertilizer under the brand "Megarhizo". Production activities still use manual bookkeeping processes. So it takes a long time for distribution from the warehouse to the production location. Miscalculations often occur in warehouses resulting in inappropriate production targets, due to insufficient or expired materials due to being in the warehouse for too long. This problem often occurs because the recording process is not thorough and results in stock buildup or stock shortages in the warehouse. So we need a system that can easily and quickly manage data so that these things don't happen again. Digitalization of the sales process is a solution to this problem, fertilizer products are products that are different from other production, because fertilizer is a product that is monitored so the price of fertilizer should not burden the public. By digitizing sales, companies can directly monitor stock and products sold from each distribution location to the resellers. So the number of products sold and prices can still be monitored, besides that the company can also find out the effectiveness of fertilizer production.
