Abstract

Cyanide (CN-) is a compound that is commonly found in food and can cause health problems and reduce the bioavailability of nutrients in the body and even death, so the presence of cyanide needs to be controlled.Ninhydrin functions as a cyanide complexing reagent formed from the oxidation of thiocyanate which can be used to identify the presence of cyanide. This study aims to develop a cyanide identification method using the ninhydrin cyanide test kit. The test kit is a tool that can be used to detect levels of a compound quite accurately which is easy to use and operate by various groups. The reaction of ninhydrin with cyanide forms hydrindantine which will give a red color to the strip containing Na2CO3. This study uses a qualitative method with the type of pre-experimental research. The results of the data obtained were analyzed using a descriptive test that uses a pie chart frequency so that the results for cassava were positive at 93.3%, while the results were negative at 6.67%. So from this research it can be concluded that the development of a cyanide examination method using the Ninhydrin Test Kit method can be used to identify samples that are suspected to contain free cyanide qualitatively.

Abstract

Hypertension therapy evaluation requires longitudinal information that connects blood pressure measurements, laboratory examination results, and medication history. In practice, these data are often recorded separately, making continuous evaluation difficult. This study aims to develop e-LabCare as a digital health information system that integrates laboratory data, blood pressure, and antihypertensive therapy within a single longitudinal platform. The system was developed using the Waterfall method consisting of requirement analysis, system design, implementation, testing, and evaluation. The developed modules include user management, laboratory examination recording, systolic and diastolic blood pressure recording, medication history including drug name, dose, frequency and treatment period, examination history, trend visualization, and health insight. Initial functional testing using simulated data showed that the main system functions could operate according to their intended processes. The system is currently capable of displaying health parameters and medication periods in an integrated manner. However, clinical effectiveness has not yet been evaluated because testing still uses simulated data. e-LabCare therefore provides a functional prototype for longitudinal health-data integration and can be further evaluated through usability testing and validation using real-world data.
