The covid pandemic that has occurred for more than two years is still not over. Even in January 2022, with the new variant, Omicron, the number of COVID-19 cases has increased dramatically. According to statistics, on January 25 there were 3,559,000,464 new cases of COVID-19 and an average of 7 days as many as 3,397,073 cases. Therefore, it is important to take preventive measures to avoid the COVID-19 virus. One of them by eating foods high in antioxidants. Some fruits that are high in antioxidants are Averrhoa bilimbi L and Phaleria macrocarpa. Flavonoids are one of the types of antioxidants found in Averrhoa bilimbi L and Phaleria macrocarpa which function to inhibit the formation of Reactive Oxygen Species (ROS) by inhibiting enzymes in the formation of ROS and increasing the regulation and protection of antioxidants to prevent various negative impacts such as degenerative diseases and decreased immunity so that it can prevent exposure to the COVID-19 virus. The purpose of this study was to determine the levels of flavonoids in the combination of extracts of Averrhoa bilimbi L and Phaleria macrocarpa. The method used is the UV-VIS spectrophotometry method. The result of this research is that the flavonoid content of Averrhoa bilimbi L is 2.32 mg/g, the extract of Phaleria macrocarpa is 4.83 mg/g and the combination of the two is 4.77 mg/g. From these results, it can be said that the extract of Phaleria macrocarpa has the highest flavonoid content of 4.83 mg/g. Abstrak: Pandemi COVID-19 yang sudah terjadi lebih dari dua tahun masih belum berakhir bahkan pada Januari 2022 dengan adanya varian baru yaitu omicron, jumlah kasus COVID-19 meningkat drastis. Menurut statistik, pada 25 Januari terdapat 3.559.000.464 kasus baru COVID-19 dan rata-rata 7 hari sebanyak 3.397.073 kasus. Oleh karena itu pentingnya upaya pencegahan agar terhindar dari virus COVID-19. Salah satunya dengan mengonsumsi makanan tinggi antioksidan. Beberapa buah yang tinggi antioksidan adalah buah belimbing wuluh dan buah mahkota dewa. Flavonoid merupakan salah satu jenis antioksidan yang terdapat pada buah belimbing wuluh dan buah mahkota dewa yang berfungsi menghambat pembentukan Reactive Oxygen Species (ROS) dengan menghambat enzim dalam pembentukan ROS dan meningkatkan regulasi serta proteksi dari antioksidan sehingga dapat mencegah berbagai dampak negatifnya seperti penyakit degenerative dan penurunan imunitas sehingga dapat mencegah dari terpaparnya virus COVID-19. Tujuan penelitian ini yaitu untuk mengetahui kadar flavonoid pada kombinasi ekstrak buah belimbing wuluh dan buah mahkota dewa. Metode yang digunakan yaitu metode spektrofotometri UV-VIS. Hasil penelitian ini yaitu didapatkan kadar flavonoid buah belimbing wuluh sebesar 2.32 mg/g, ekstrak buah mahkota dewa sebesar 4.83 mg/g dan kombinasi dari keduanya sebesar 4.77 mg/g. Dari hasil tersebut dapat disimpulkan bahwa ekstrak buah mahkota dewa memiliki kadar flavonoid tertinggi yaitu 4.83 mg/g.

The use of paracetamol in excessive doses can increase the hepatotoxicity effect, which causes acute hepatocellular injury. Dewa leaves (Gynura pseudochina (L.) DC) contain flavonoids, saponin, and tannin. This study aimed to determine the effect of ethanol extract from dewa leaves in reducing the impact of paracetamol induction on SGPT and SGOT levels and liver histology of white rats (Rattus norvegicus). The test was grouped into five treatment groups, namely: normal control; negative control with paracetamol induction 315mg/KgBW; Dewa leaf extract was administered with three variations in dosage, namely 3.15mg/KgBW, 3.50mg/KgBW and 3.85mg/KgBW and each treatment group consisted of 5 rats as replications. Dewa leaf extract was administered to the experimental animal, followed by the administration of paracetamol 8 hours after the extract was given orally; both treatments were given for 14 days. Measurement of SGPT and SGOT levels uses the photometric method. The hepatoprotective effect was further verified by histopathology of the liver. Liver histology was made using the paraffin method. SGPT levels, SGOT levels, and Hepatocyte Damage Scores were analyzed using Analysis of Variance (ANOVA); if the results are significant, continue with the Least Significance Difference (LSD) test at a significance level of 5%. The results of this study show that the administration of dewa leaf extract was not able to significantly reduce SGPT and SGOT levels in rats. The administration of dewa leaf extract at doses of 3.50mg/KgBW and 3.85mg/KgBW significantly prevented histological damage to rat livers.

Praktikum menjadi salah satu sarana dalam peningkatan kompetensi IPA bagi siswa di sekolah. Implementasi dari praktikum dapat memberikan dampak positif dalam peningkatan kompetensi karena pembelajaran akan lebih berkesan dan mudah dipahami jika dilaksanakan dengan aksi yang dikerjakan langsung oleh siswa. Hal tersebut yang mendasari sekolah, baik di tingkat SMP maupun SMA, melakukan banyak praktikum untuk meningkatkan kompetensi IPA yang dimiliki muridnya. Berdasarkan dari hasil survei yang telah dilakukan, banyak implementasi praktikum yang selinier dengan pembelajaran IPA di jenjang SMP sehingga program kerja yang dilakukan berfokus pada kegiatan praktikum yang dapat menunjang peningkatan kompetensi siswa di SMP Djama’atul Ichwan, Surakarta. Program-program tersebut terdiri dari 5 program kerja yang satu di antaranya merupakan program kerja sama dengan dosen Grup Riset Biomaterial Hewan Prodi Biologi FMIPA UNS berupa pendampingan praktik mikroskopis. Kelima program kerja tersebut di antaranya, sosialisasi pengelolaan limbah organik melalui praktikum pembuatan eco-enzyme; praktikum pembuatan insektarium dalam upaya meningkatkan pembelajaran klasifikasi dan sistematika hewan; praktikum pengamatan morfologi dan anatomi hewan uji laboratorium; praktikum pembuatan preparat sederhana sebagai objek pengamatan dengan mikroskop; serta kegiatan mini project yang menekankan skill kerja sama dan kepemimpinan antarsiswa dengan mengimplementasikan pembelajaran IPA yang telah didapat.

Persistent hyperglycemia in type 2 diabetes mellitus (T2DM) increases the risk of lipid peroxidation that produces malondialdehyde (MDA). Red spinach mira extract (RSME) contains anthocyanins and beta carotene, both of which have the potential as antioxidants in reducing fasting blood glucose (FBG) and MDA levels. The purpose of the study was to determine the effect of RSME administration on FBG and MDA levels in T2DM. The research method was true-experimental with pretest-posttest. The study used 30 male Wistar rats, and divided into 5 groups, namely the normal group and given standard diet, K- T2DM rats and given a standard diet, K+ T2DM rats and given acarbose drug therapy 1.8 mg/200g/day, P1 T2DM rats and given a dose of RSME 688 mg/200g Body weight (BW) and P2 T2DM rats and given a dose of RSME 1376 mg/200g BW for 14 days. Statistical analysis of FBG and MDA using One Way Anova test and continued with Post Hoc test to determine the difference between groups, while to determine the effect using Paired t-test. The results of the study after intervention for 14 days, all groups given RSME experienced a decrease in FBG levels P1 by 158.60 mg/dl (p=0.000), KP2 by 180 mg/dl (p=0.000) and MDA KP1 decreased by 6.01 nmol/mL (p=0.000) and KP2 by 7.75 nmol/mL (p=0.000) and there was significant value (p<0.05). The study concluded that the best dose is KP2, which reduces FBG levels by 180.84 mg/dl and MDA by 7.75 nmol/ml, the highest decrease compared to the other doses.

This study aims to examine the effectiveness of G. parviflora extract in reducing fasting blood glucose (FBS) levels and improving lipid profiles. The research design used was a laboratory experiment with a Completely Randomized Design (CRD). This study was conducted from June 2024 to January 2025 in the Laboratory of Biology Study Program and Integrated Mathematics and Natural Sciences Laboratory. Rats were divided into five groups, namely negative control, positive control (glibenclamide 5 mg/kgBB), and three treatment groups of bribil extract with doses of 400 mg/kgBB, 600 mg/kgBB, and 800 mg/kgBB. Parameters measured included GDP levels and lipid profiles (total cholesterol, triglyceride, HDL, and LDL levels). Data analysis was performed using one-way ANOVA test and Tukey's Post Hoc further test. The results showed that the ethanol extract of bribil (Galinsoga parviflora) doses of 600 and 800 mg/kgBB effectively reduced GDP levels, total cholesterol levels, triglyceride levels, LDL levels, and HDL levels of rats (Rattus norvegicus) T2DM model. These results indicate that bribil extract has potential as a therapeutic agent for T2DM. These findings suggested the possibility of Galinsoga parviflora extract as a DMT2 therapeutic agent.
