Abstract

Mangifera foetida, commonly referred to as bacang, is a tropical fruit tree of the Anacardiaceae family widely used in traditional medicine throughout Southeast Asia for a variety of therapeutic purposes. Recent scientific studies have validated many of these ethnomedicinal uses by uncovering a diverse phytochemical composition alongside notable pharmacological activities. This review synthesizes current knowledge on the nutritional content, bioactive compounds, and pharmacological effects of M. foetida, with particular focus on its antioxidant, antimicrobial, cytotoxic, antidiabetic, and anti-inflammatory properties. Key secondary metabolites, including mangiferin, phenolic compounds, flavonoids, and essential oils, are believed to underpin its therapeutic efficacy. Moreover, the fruit and other plant parts provide considerable nutritional benefits, supplying essential vitamins, minerals, and dietary fiber. Despite these promising findings, further investigations are needed to clarify underlying mechanisms, improve extraction techniques, and evaluate clinical effectiveness. This review seeks to establish a comprehensive reference to support future research and facilitate the development of M. foetida-derived nutraceuticals and pharmaceuticals.

Abstract

The donkey ear taro plant (Alocasia polly) is an ornamental Araceae family plant with broad leaves capable of absorbing air pollutants. This research examined the macroscopic and microscopic characteristics of A. polly leaves for botanical identification and pharmaceutical potential assessment. The research methods included sample preparation and macroscopic, organoleptic, and microscopic observations of fresh leaves and leaf powder. Macroscopic observations revealed shield-shaped leaves (peltatus) with pointed tips (acuminatus), ear-like lobed base (auriculatus), smooth glossy surface (nitidus), dark green upper surface, purplish lower surface, pinnate venation (penninervis), and wavy margins (repandus). The leaves averaged 33 cm in length and 16.5 cm in width. Organoleptic examination showed fresh leaves with dark green upper surfaces and purplish-brown lower surfaces, characteristic leaf aroma, and tasteless properties. The leaf powder exhibited similar dark green coloration, characteristic aroma, and tasteless qualities. Microscopic analysis of both fresh leaves and powder revealed epidermal cell structures, spiral-type vascular bundles, anomocytic stomata, multicellular and unicellular trichomes, and calcium oxalate crystals. These findings provide fundamental botanical identification data for A. polly leaves. Further research is recommended, including non-specific parameter testing and phytochemical screening, to explore the plant's pharmacological potential more comprehensively.

Abstract

Soil insects play a vital role in maintaining forest ecosystem functions, yet their diversity in Indonesian protected areas remains underexplored. This study aims to analyze the diversity, dominance, and evenness of soil insect communities in three habitat zones riparian, forest edge, and forest interior within Aiknyet Natural Tourism Forest, Lombok Barat. A descriptive quantitative approach was used, with data collected via pitfall traps and analyzed using Shannon-Wiener (H'), Simpson (C), and Pielou (E) indices. A total of 4,524 individuals representing 68 species, 31 families, and 9 orders were recorded. The riparian zone showed the highest diversity (H' = 3.41) and evenness (E = 0.83), while the forest interior had the highest dominance (C = 0.17) due to the prevalence of Hypoponera opaciceps. These findings indicate that high individual abundance does not necessarily equate to high biodiversity. The study concludes that habitat heterogeneity strongly influences soil insect community structure. Scientifically, the results highlight the need for habitat-based conservation strategies and support the use of soil insects as ecological indicators in tropical forest management.

Abstract

: The armyworm (Spodoptera exigua) is one of the most common plant pests that lower plant yields.  The purpose of this study is to ascertain how armyworm (Spodoptera exigua) attacks on long bean plants are impacted by botanical pesticides and planting distance.  This study employs experiments and is quantitative in nature.  In this investigation, papaya leaf trials and garlic peels were used as plant insecticides in covert studies.  The one-way ANOVA test was the statistical method employed in this investigation. The findings demonstrated that while the botanical concentration had no effect on plant height or attack severity, it significantly affected the percentage of attacks and the leaf area index.  Plant height, attack intensity, attack %, and leaf area index were not significantly affected by planting distance in long bean plants.  The study's conclusions include the need for more research on plant insecticides that use plant leaves to fend against attacks, particularly in lowering the incidence of armyworm attacks.

Abstract

Serinting Beach, located within the Mandalika Special Economic Zone (SEZ), is an intertidal area with high biological potential for tourism. However, studies on its Echinodermata community remain limited. The existence of this community is crucial as an indicator of coastal ecosystem health and holds potential for developing educational ecotourism, such as reef walking tours. This research aims to analyze the species richness and composition of the Echinodermata community, along with its ecological indices (diversity, evenness, and dominance). Data was collected in March 2025 using the transect-quadrat method, employing three transects perpendicular to the coastline and 15 quadrats, each measuring 2 × 5 m². The study results revealed 21 Echinodermata species, consisting of 10 genera and 9 families from four classes: Asteroidea, Ophiuroidea, Echinoidea, and Holothuroidea. The community composition was dominated by Ophiocoma scolopendrina (43.90%), Echinometra mathaei (21.33%), and Echinometra sp. (16.77%). The diversity index (H') was 1.59; the evenness index (E) was 0.62; and the dominance index (D) was 0.28. Tripneustes gratilla populations were found in low numbers and are suspected to be under pressure due to traditional reef gleaning activities. The findings of this study are expected to serve as a basis for enviromental management and the development of educational tourism, like reef walking tours, in the intertidal zone of the Mandalika SEZ.

Abstract

Serinting Beach is located within the Special Economic Zone of Mandalika, where ongoing massive tourism facility development may impact the intertidal coral communities. The intertidal zone of Serinting Beach is also a primary location for reef gleaning, which impacts corals in the intertidal area. Considering that corals are the foundational components of reef ecosystems, the prospective development of this designated super-priority tourism area may exert significant impacts on the intertidal coral communities. This investigation aimed to delineate the coral community structure within the intertidal zone of Serinting Beach, situated in the Mandalika Special Economic Zone (SEZ). Sampling was executed via the transect-quadrat method. Measured variables encompassed coral life forms, genera, families, and the respective colony counts. The study identified 323 coral colonies distributed among 17 genera and 9 families. Compositions of three predominant genera were Heliopora 25.39%, Favites 24.77%, and Porites 22.91%. The Faviidae family exhibited the highest compositional abundance, contributing 37.15%, followed by Helioporidae 25.39% and Poritidae 23.53%. Furthermore, eight distinct coral life forms were documented in the intertidal zone, with massive coral representing the predominant form at 35.60%, followed by coral encrusting 26.01%, and blue coral 25.39%. Ecological indices indicated a moderate level of coral diversity (H'=1.98), accompanied by an unstable evenness index (E=0.70) and a low dominance index (C=0.19).

Abstract

Soil insects play an important role as indicators of ecosystem balance, however information about soil insects especially the distribution patterns of soil insects across microhabitat in the Lemor Botanical Gardens is still limited. This research aimed to analyze the distribution patterns of soil insects across various types of microhabitats in the Lemor Botanical Garden. This type of research is descriptive exploratif where soil insect samples were taken using the pitfall traf method, soil drill and continued using berlese tullgren. Sampling was carried out for 3 repetitions at two stations, namely station 1 in the Ex Situ area and station 2 in the In Situ area of the Lemor Botanical Garden. Each station consists of 10 sampling plots where each plot consists of 3 microhabitats namely litter, soil surface and subsurface. The research data were analyzed using the Morisita Index. The results indicated that the distribution of soil insects showed variation across microhabitats: in the litter microhabitat, 14% of individuals exhibited a clumped distribution and 1% an uniform distribution; in the soil surface microhabitat, 32% were clumped and 2% uniform distributed; and subsurface microhabitats, 7%  were clumped and 1% uniform distributed. These findings suggest that the dominant distribution pattern of soil insects across all microhabitats is clumped followed by a lesser degree of uniform distribution. The research is expected to provide insights to the public regarding the distribution patterns of soil insects across various types of microhabitats in the Lemor Botanical Garden.

Abstract

The Bagek Kembar Mangrove Ecosystem Essential Area (EEA) in West Lombok is a critical habitat that supports various aquatic organisms, including mollusks. This study aimed to identify and analyze the diversity of mollusks from the classes Gastropoda and Bivalvia, within the Bagek Kembar mangrove ecosystem. Sampling was conducted from February to April 2025 using the quadrat transect method, and data were analyzed using the Shannon-Wiener diversity index (H′), Pielou’s evenness index (E), and Simpson’s dominance index (C). A total of 2,368 individual mollusks were recorded, comprising 20 species: 16 Gastropods and 4 Bivalves. The family Potamididae from the class Gastropoda was the most dominant, with Cerithidea cingulata being the most abundant species. Gastropods exhibited moderate diversity (H′ = 2.20), high evenness (E = 0.79), and low dominance (C = 0.15), while Bivalves showed low diversity (H′ = 0.61), moderate evenness (E = 0.44), and moderate dominance (C = 0.70). These results indicate that mollusk diversity in the area is at a moderate level. The findings highlight the importance of mangrove ecosystems in maintaining mollusk diversity and support their use as bioindicators in environmental monitoring and local conservation strategies.
