Abstract

This research is an ethnobotanical study of the traditional food Wa'ai Zamu, a form of cultural heritage of the Ende people, East Nusa Tenggara. The objective was to document local knowledge regarding the use of plants in making Wa'ai Zamu and the cultural values it embodies. The study employed a qualitative approach with ethnographic methods. Data were obtained through in-depth interviews with 10 key informants selected purposively, consisting of traditional leaders, women traditional food processors, and local cultural experts. Triangulation techniques were used through participant observation and literature review to strengthen the validity of the data. The results indicate that Wa'ai Zamu uses various types of local plants with nutritional value and symbolic functions in traditional rituals. Information regarding nutritional content comes from informants and is partially supported by previous literature references.

Abstract

Adolescent Idiopathic Scoliosis (AIS) is the most common spinal deformity seen by general practitioners, pediatricians, and spine surgeons in adolescents aged 10–18 years. Also known as “late-onset” scoliosis, AIS is typically characterized by a lateral curvature of the spine of ≥10° on radiological examination. This article aims to examine the characteristics, prevalence, diagnostic methods, and risk factors of AIS through a literature review. The method used was a literature review of several scientific articles from the PubMed, Scopus, and Google Scholar databases published within the past 10 years. The results of the study indicate that AIS is more common in females, with a global prevalence ranging from 0.47 to 5.2%. Physical examinations, such as the Adams forward bend test, are common initial screening methods for detecting postural abnormalities, such as rib hump or shoulder asymmetry. The conclusions of this review emphasize the importance of early detection of AIS to prevent progression of the disorder and long-term biomechanical complications.

Abstract

Leri water is a household waste from washing rice, known to contain various important nutrients, such as vitamins A, C, B1, carbohydrates, phosphorus, potassium, magnesium, nitrogen, and iron. The nutritional content in rice washing water can be used to support the growth and development of chili plants. This study aims to determine the effect of leri water on the growth of plant height and number of leaves of cayenne pepper plants (Capsicum frutescens L). The design used was a Completely Randomized Design (CRD) consisting of 5 treatments with 3 replications P1 0%, P2 25%, P3 50%, P4 75%, and P5 100%. P1 (without using leri water), P2 (250ml leri water + 750 plain water), P3 (500ml leri water + 500ml plain water), P4 (750ml leri water + 250ml plain water), and P5 (without using plain water). The variables observed were plant height and number of cayenne pepper leaves. The results of the study showed that the provision of leri water had an effect on the vegetative growth of cayenne pepper plants (Capsicum frutescens L.), the best results were seen in the P5 treatment with 100% leri water without a mixture of ordinary water, and the lowest results were in the P1 treatment without using leri water.

Abstract

River water pollution due to domestic, industrial, and agricultural waste poses a serious threat to aquatic ecosystems and human health. One environmentally friendly approach to monitoring water quality is through the use of aquatic plants as bioindicators. This study aims to inventory the types of aquatic plants that have the potential to be bioindicators of river water quality based on their sensitivity to pollutants and their relationship to water quality. This study was conducted through a literature study by analyzing articles from the Google Scholar, DOAJ, and GARUDA databases, published between 2015-2025, totaling 52 relevant articles regarding aquatic plants as bioindicators of river water quality. Using a qualitative content analysis and descriptive synthesis approach. The results of the analysis indicate that 12 species of aquatic plants have the potential to be bioindicators of river water quality. Some prominent species include: Cyperus papyrus, Echinodorus palaefolius, Eichhornia crassipes, Hydrilla verticillata, Ipomoea aquatica, Lemna minor, Limnocharis flava, Microsorum pteropus, Nymphaea sp., Pistia stratiotes, Salvinia molesta, and Typha angustifolia. Based on their sensitivity to pollution, aquatic plants can be grouped into Eichhornia crassipes and Ipomoea aquatica (highly sensitive), Pistia stratiotes and Salvinia molesta (sensitive), Nymphaea sp. and Limnocharis flava, Lemna minor, and Cyperus papyrus (pollution-tolerant), and Hydrilla verticillata and Microsorum pteropus (highly adaptable). This research can provide an alternative for assessing water quality through aquatic plants and increase public knowledge about aquatic plant species as bioindicators.

Abstract

Hypercholesterolemia is a major risk factor for cardiovascular disease and requires alternative therapies derived from natural products to minimize the side effects of synthetic drugs. This study aimed to evaluate the potential of bioactive compounds from Antidesma bunius as hypocholesterolemic drug candidates through an in silico approach, including drug likeness screening, toxicity prediction (GUSAR), and molecular docking against the HMG-CoA reductase enzyme (PDB ID: 1HWK). From 104 compounds identified via GC-MS, 52 met the Lipinski’s Rule of Five (Ro5) criteria, indicating favorable oral pharmacokinetics. Toxicity prediction using GUSAR revealed that most compounds had oral LD₅₀ values >2000 mg/kg and were classified as having low to non-toxic profiles according to OECD standards Compounds such as Farnesol, 3-Deoxy-d-mannoic lactone, and Ambrettolide were classified in toxicity class 5 to non-toxic based on their high LD₅₀ values, particularly through oral and subcutaneous routes, indicating a wide safety margin. Docking analysis showed that Ambrettolide (−6.5 kcal/mol) and Acenapthylene (−6.4 kcal/mol) had stronger binding affinities than Pravastatin (−6.2 kcal/mol), a standard control drug, suggesting that certain natural compounds from A. bunius may possess comparable or superior hypocholesterolemic activity. Furthermore, 2,4-Dihydroxy-2,5-dimethyl-3(2H)-furan-3-one displayed a promising combination of safety, pharmacokinetic properties, and binding affinity. These findings suggest that A. bunius contains several natural compounds with the potential to be developed into safe and effective herbal therapies for hypercholesterolemia.
