Abstract

Diabetes mellitus is a long-lasting metabolic condition marked by high blood sugar levels resulting from insufficient insulin production. This study aims to evaluate the profile of antidiabetic drug use in outpatients with diabetes mellitus at a private hospital in Bandar Lampung and assess its compliance with current treatment guidelines. This study employed a non-experimental method with a retrospective descriptive design based on medical records and outpatient prescriptions from January to July 2025. The data analyzed included gender, age, comorbidities, and the types of antidiabetic drugs used. The results showed that type 2 diabetes mellitus patients were more prevalent in women (60.78%) than in men (39.22%), with the largest group of diabetes mellitus patients falling within the 45–60 age group. Most patients also had comorbidities, with hypertension being the most common. The pattern of medication use showed that biguanides, particularly metformin, were the most commonly prescribed drugs as first-line therapy. In general, the use of antidiabetic drugs in outpatients at the hospital was in accordance with the PERKENI treatment guidelines.

Abstract

Microalgae play an important role in aquatic ecosystems as primary producers and have significant potential as a sustainable source of protein. One of the microalgae with high economic value is Arthrospira platensis, which is rich in bioactive compounds and protein content. Light is a key factor influencing microalgae growth, particularly its wavelength and spectrum, which can affect biomass production and biochemical composition. This study aimed to analyze the effect of different LED light wavelengths (red, blue, and a combination of red–blue) on the growth performance and protein content of Arthrospira platensis. The experiment was conducted in January 2026 using a completely randomized design with three treatments and three replications. The microalgae were cultivated in Walne medium under controlled conditions with continuous aeration for 14 days. Growth was monitored daily, and protein content was analyzed using a UV-Vis spectrophotometer at wavelengths of 280 nm and 260 nm. The results indicated that different light wavelengths significantly influenced the growth and protein content of Arthrospira platensis. The combination of red–blue light showed better performance compared to single wavelengths in enhancing biomass production and protein content. In conclusion, the use of combined LED light spectra can optimize the cultivation of Arthrospira platensis and improve its potential as an alternative protein source
