Abstract

Type 2 diabetes mellitus is a global health problem that continues to increase. One alternative approach in managing diabetes is using natural materials with antihyperglycemic activity. This study aims to evaluate the effectiveness of solid lipid nanoparticles (SLN) containing Kabau seed extract (Archidendron bubalinum (Jack) I.C. Nielsen) coated with trimyristin in reducing blood glucose levels in hyperglycemic rats. Extraction was carried out by maceration using 96% ethanol, while SLN was synthesized by high-speed homogenization and ultrasonication methods. Particle size analysis showed an average diameter of 262.61 nm with a polydispersity index (PDI) of 0.144, indicating a homogeneous formulation. Phytochemical testing showed that Kabau seed extract contains alkaloids, flavonoids, tannins, and saponins contributing to antihyperglycemic activity. In vivo tests on Mus musculus showed that 20 % concentration of Kabau SLN reduced blood glucose levels by up to 97 mg/dL, approaching the effectiveness of metformin (104 mg/dL). Statistical analysis of ANOVA and BNT test showed significant differences between treatments. These results indicate that Kabau SLN has the potential as a candidate for phytopharmaceuticals in managing type 2 diabetes mellitus.

Abstract

Halophilic bacteria, a group of extremophiles adapted to high-salinity environments, have emerged as valuable sources of relevant biocatalysts. This review aims to compile and analyse current knowledge on the enzymatic potential of halophilic bacteria. Using a systematic literature review as its primary methodology to collect, examine, and integrate academic findings on halophilic bacteria as promising sources of biocatalysts. This review highlights that halophilic bacteria possess remarkable physiological and biochemical adaptations that enable them to survive osmotic stress, with recent advances in genetic engineering and synthetic biology enhancing their enzyme production and functional efficiency. These findings underscore their potential as robust and efficient biocatalysts for sustainable industrial applications. In conclusion, halophilic bacteria represent valuable resources for biotechnology, particularly in extreme conditions where conventional enzymes fail. Future research should focus on in-depth genomic and proteomic analyses, metabolic engineering for optimized enzyme yields, industrial-scale feasibility studies, environmental impact assessments, and cross-disciplinary collaborations to fully harness their capabilities in real-world applications.

Abstract

This community engagement initiative aimed to address organic waste management issues at the Angkringan Kampung Belimbing (AKB) restaurant by introducing innovations in liquid organic fertilizer (LOF) production and environmental education. The approach included initial observation, awareness sessions, hands-on LOF training using kitchen waste and Effective Microorganisms 4 (EM4), and evaluation through application on water spinach and shallot plants. Results indicated an increase in community understanding of circular economy principles and sustainable waste management. The LOF produced proved effective in enhancing plant growth and opened opportunities for eco-friendly local entrepreneurship. This program demonstrates that combining educational and practical strategies can significantly strengthen community awareness and capacity in independently managing organic waste in a sustainable manner.

Abstract

Tanaman Scleria poaeformis merupakan salah satu sumber yang kaya akan jamur endofit. jamur endofit merupakan penghasil senyawa metabolit sekunder yang memiliki bioaktivitas seperti sitotoksik dan antimikroba. Penelitian ini bertujuan untuk mengisolasi dan mengetahui senyawa metabolit sekunder dari fungi Trichoderma sp pada tanaman Scleria poaeformis. Isolat fungi di kultivasi pada media PDA selama ±2 minggu. Trichoderma merupakan fungi patogen penyebab penyakit antraknosa pada tumbuhan. Penelitian ini bertujuan untuk mendapatkan senyawa metabolit sekunder fungi Trichoderma sp. Yang diisolasi dari tumbuhan Scleria poeformis. Penelitian ini dilaksanakan di Laboratorium Mikrobiologi dan Laboratorium Genetika dan Bioteknologi Jurusan Biologi, Fakultas Matematika dan Ilmu Pengetahuan Alam, Universitas Sriwijaya, Indralaya Tahapan Penelitian meliputi inokulasi fungi Trichoderma sp, kultivasi, ekstraksi dan isolasi metabolit sekunder. Isolasi senyawa metabolit sekunder pada fungi Trichoderma sp dilakukan dengan kromatografi kolom dan mendapat 37 eluat  yang merupakan senyawa fenol, alkaloid, fenolik, flavonoid, terpenoid, steroid, dan poliketida.
