Abstract

Algae are lower plants that do not have differentiated structures such as roots, stems, and leaves; although they may appear to have differences, they are actually just thallus forms. Macroalgae have macroscopic body shape and size consisting of fronds without distinct roots, stems, and leaves. Macroalgal diversity is not only reflected in their ecological and economic significance but also in their high species richness and wide geographical distribution within aquatic ecosystems. However, research on the species diversity of macroalgae in Budo Tourism Village Beach, North Minahasa remains limited. This study aims to identify the macroalgal species in the Budo Tourism Village, Wori, North Minahasa area. The research employed the line transect and quadrat-based sampling method, which was implemented at two distinct station locations: Station I (rocky reef substrate) and Station II (sandy-muddy substrate). Macroalgae identification was facilitated by utilizing the comprehensive identification textbooks. The research reveals the presence of four macroalgal species, comprising three brown algae (Phaeophyceae), namely Padina boergesenii, Sargassum llinearifolium, Turbinaria ornata and one red algae (Rhodophyceae), Gracilaria corticata. Sargassum linearifolium, Padina boergesenii, and Gracilaria corticata was found in rocky reef substrate. Turbinaria ornate and Padina boergesenii was found in sandy-muddy substrate.

Abstract

Celery and Green Gedi leaves have been long considered traditional topical supplements to support hair growth. They contain flavanoids that are efficacious to induce keratinocyte proliferation. However, the research about whether the combination of celery and green gedi leaves can still provide an effect is limited. This current study aims to determine the effect of the combination of ethanol extracts of celery leaves and green gedi leaves on white rat hair growth. This is laboratory experimental research to compare the hair growth in three different groups with normal and positive control. Animals were randomly grouped (n=3 for each group) and then given a combination of leaf extracts and carbopol with a concentration of 17.5%:10%; 27.5%:15%;37.5%:20%. A normal control group was left untreated, while another group was treated with 2% minoxidil as positive control. The results of measuring fur weight on day 21 showed that the treatment group given the combination of extracts did affect the growth of rat hair. Statistical tests using one-way ANOVA showed a p-value of <0.001 which means there is a significant difference in the average hair weight of rats treated. LSD post hoc test showed that treatment with a 17.5%:10% concentration ratio was significantly different from the other treatments. It can be concluded that the combination of celery leaf extract and gedi leaf positively affects rat hair growth.

Abstract

This study aims to determine the potential of natural sterol compounds from Tin (Ficus carica) leaves as anticholesterolemic using in silico test. This study employed an in silico approach using molecular docking methods to evaluate the potential of sterol compounds as anti-hypercholesterolemic agents, in comparison to other references compounds. Data processing and interpretation were conducted using molecular databases for both ligands and target proteins. The analysis utilized several computational tools, including PyRx 0.8, PyMOL, LigPlus, and Discovery Studio 2016 Client. The compounds used in this research  were sterol, fluvastatin and simvastatin (as control), with HMG CoA reductase as the target protein. The results showed that the highest binding affinity value was fluvastatin which is -8.3 kcal/mol. Sterol compounds are compounds with lower binding affinity which is -7.7 kcal/mol. From the visualization results, it is known that the binding distance between sterol compounds with target proteins (HMG CoA reductase) is between 2.69 to 5.49 Å, and the binding distance between simvastatin compounds with target proteins (HMG CoA reductase) is between 2.76 to 5.36 Å, and the binding distance between fluvastatin compounds with target proteins (HMG CoA reductase) is between 1.95 to 5.26 Armstrong. While based on the comparison of the binding side of strerol, simvastatin and fluvastatin, it is known that the three compounds have the same site because they bind to the same amino acid residues, namely ARG (B: 515), TYR (A: 533), TYR (B: 533), TYR (B: 517), PRO (A: 511). The results of this research indicate that the natural sterol compounds found in Tin (Ficus carica) leaves have potential as anti-hypercholesterolemic agents, based on reverse docking analysis. These sterol compounds bind to the same active site as the control drugs, simvastatin and fluvastatin, and exhibit comparable binding affinity values

Abstract

Indonesia is a highly biodiverse country, second only to Brazil. This gives Indonesia enormous potential in ethnopharmacology. Previous studies have shown that the leaves of the Brugmansia suaveolens plant, also known as Angel trumpet, have high antioxidant activity. The aim of this study is to test the antioxidant activity of B. suaveolens flowers and conduct quantitative screening to determine which compounds play the greatest role in their antioxidant activity. This research used the DPPH test and Gas Chromatography-Mass Spectrometry (GC-MS) screening. Ascorbic acid was used as the comparator in this study. Before the DPPH and GC-MS testing, the samples were extracted using the cold maceration technique with a 95% ethanol solvent. Then, the samples were concentrated using a rotary evaporator. The IC₅₀ value of the ethanol extract of B. suaveolens flowers is 196.16 µg/mL, while the IC₅₀ value of ascorbic acid, the comparator, is 3,814 µg/mL. This result shows that the ethanol extract of B. suaveolens flowers has moderate antioxidant activity. Screening bioactive compounds with GC-MS showed that Hexadecenoic acid and Octadecanoic acid play the biggest role in antioxidant activity. However, the compound with the highest content in the ethanol extract of B. suaveolens flowers is scopolamine.

Kolongan Village is one of the villages in Talawaan district of North Minahasa, North Sulawesi. In the village of Kolongan, some springs are potentially a clean water source for the people of the village. This research aims to analyze the quality of the springs in the village of Kolongan Talawaan, Prefectures as a water source. This type of research is quantitative, and the method used in this research is the Indonesian National Standard (SNI) according to the water quality parameters that have been established with the direct observation plan of the physical properties of water and with the laboratory testing plan for the observation of water chemical and biological properties with indicators of iron, sensitivity, manganese, E.coli, taste, and smell. The research was conducted from July 24, 2021, to September 20, 2021. The water quality measurement results in the spring in one village of Kolongan showed iron <0.0086 mg/L, iron 69-93 mg/ L, manganese 0.03-0.07 mg / L, E. coli, 11 CFU, not sensitive and odorless. Water source 2 showed iron <0.086 mg / l, density 75-85 mg/ l, manganese 0.02-0.03 mg/l, and E. coli, 3.6-9.2 CFU, is not sensible and odorless. The pollution index calculation indicates that the springs in Kolongan Village belong well. However, because they still contain biological reservoirs, it is necessary to have an advanced process for them to be consumed by the community.
