Abstract

This study aimed to analyze the types of damage to the mangrove forest ecosystem and address abrasion as part of disaster mitigation efforts on Sulamanda Beach, Mata Air Village, Kupang Regency. The research employed a quantitative and qualitative descriptive method using plot sampling for data collection. Observed data included mangrove density, frequency, and Important Value Index (IVI). The results identified six mangrove species: Avicennia marina, Avicennia alba, Lumnitzera racemosa, Rhizophora stylosa, Bruguiera parviflora, and Sonneratia alba. Among these, Bruguiera parviflora had the lowest density (1.7 stands/ha) and relative density (4.52%), while Sonneratia alba showed the lowest frequency (0.7 stands/ha) and relative frequency (12.3%). The IVI analysis revealed Sonneratia alba had the lowest value (14.14), indicating severe damage, primarily due to overharvesting for firewood. In contrast, Avicennia alba and Bruguiera parviflora exhibited the highest IVI values (55.04). These findings reflect the degraded state of mangrove communities, exacerbated by the perception of mangroves as common property with little value, leading to unsustainable exploitation. To mitigate abrasion and restore ecosystem health, community awareness programs and mangrove replanting initiatives are essential.

Abstract

Rivers, as part of the hydrological cycle, have long been an important element of human civilization. The Lematang River, which flows through South Sumatra, plays a key role in supporting local livelihoods by providing resources for activities such as sand and stone mining, fishing, and other economic activities. Water quality assessment can be effectively conducted using macrozoobenthos as biological indicators. This study aimed to assess the water quality of the Lematang River in Lahat Regency using the Family Biotic Index (FBI) and a purposive sampling approach. The FBI scores recorded at Stations I, II, and III ranged from 3.6 to 4.2, indicating slight variation between locations. Based on FBI standards, these results classify the water quality of the river in the study area as ranging from Good to Very Good.

Abstract

 The search for new therapeutic agents has increasingly focused on bioactive compounds from sponge-associated bacteria. This study investigated bacterial symbionts of marine sponges collected from the mangrove ecosystem of Tanjung Tiram, Southeast Sulawesi, which have not been previously explored for their bioactive potential. Thirty bacterial isolates were screened in triplicate for antibacterial, antioxidant, antidiabetic, and antibiofilm activities. Antibacterial activity was evaluated using the disc diffusion method, antioxidant capacity by DPPH radical scavenging assay, α-glucosidase inhibition for antidiabetic potential, and antibiofilm activity by the crystal violet binding method. Several isolates showed notable bioactivities: strain Sp.8 produced the largest inhibition zone against Escherichia coli (15 mm), and Sp.14 showed the strongest inhibition against Staphylococcus aureus (23 mm). The most active antioxidant strains (Sp.14, Sp.15, Sp.13, and Sp.6) exhibited radical scavenging activity above 80%, while Sp.13, Sp.15, Sp.31, and Sp.37 showed high α-glucosidase inhibition (>74%). Strains Sp.38 and Sp.12 significantly reduced biofilm formation by E. coli and S. aureus, respectively. These findings reveal the untapped potential of sponge-associated marine bacteria from Tanjung Tiram as promising sources of bioactive metabolites for future drug discovery.

Abstract

Mangrove plants are a type of plant that is able to grow in brackish waters in different salinity conditions in the tropics so as to form a unique and distinctive ecosystem. One of the mangrove plants that live in Indonesian waters is the mangrove of the Sonneratia genus. Empirically, parts of the mangrove plant of the Sonneratia sp. species such as fruit, bark, and leaves have been widely used as traditional medicine by the community to treat various diseases and can be used as natural antioxidants that are good for the body. The purpose of this study was to determine and analyze the potential activity of antioxidant compounds from the stem, fruit, and leaf extract of mangrove S. ovata. The antioxidant activity test method used the DPPH method which was measured by the percentage of inhibition and IC₅₀ value. The results of antioxidant activity from several test concentrations of stem, fruit, and leaf extracts obtained a very high percentage of inhibition so that the antioxidant compounds contained in the three samples could reduce free radical activity. Fruit samples had the highest antioxidant potential with an IC₅₀ value of 4.59 ppm, followed by leaf samples at 25.39 ppm and stem samples at 45.91 ppm. Thus, mangroves of the S. ovata species have the potential as natural antioxidants that are good for the body and only require <50 ppm to reduce free radicals by 50%.

Abstract

Ornamental plants are important horticultural commodities with considerable economic value, providing income for both growers and traders. Among them, Sansevieria trifasciata (commonly known as snake plant) is favored for its sword-shaped, rigid leaves. This study aimed to assess the incidence and intensity of disease in snake plants. The research was conducted from January to February 2025 using purposive sampling. Field observations revealed that the plants were affected by Colletotrichum sansevieria, causing necrotic black lesions. Disease incidence and intensity varied across locations, with the highest incidence (100%) observed in plants owned by Suwaji, Salikun, and Asep, and the lowest (10%) in those owned by Tina Purba and Sarkun. Disease intensity was greatest at Suwaji’s site (83.3%) and lowest at Tina Purba’s and Sarkun’s (3.3%). These differences were influenced by environmental factors such as temperature and humidity. Integrated disease management through physical, chemical, and biological methods is suggested as a strategy to suppress pathogen growth.

Abstract

The efforts to improve land use efficiency to increase food crop production can be done with an intercropping system. Intercropping can be done with a food crop and horticultural crop planting system, such as corn and spinach. The purpose of this study was to determine the effect of coffee skin compost on the growth and production of corn and spinach in an intercropping system. The research method used a Randomized Block Design (RBD). The treatment factor were the dose of coffee skin composts consisting of 5 treatments, each treatment repeated 3 times. The treatments used were P0: (Control without treatment) P1: 4 tons/ha of coffee skin compost (2.5 kg/plot) P2: 4.6 tons/ha of coffee skin compost (3 kg/plot) P3: 5.2 tons/ha of coffee skin compost (3.5 kg/plot) P4: 6 tons/ha of coffee skin compost (4 kg/plot). Based on the research results, it was known that intercropping of corn and spinach with the application of coffee skin compost did not have a significant effect on the growth and yield of corn plants. While in spinach plants, the application of coffe skin compost had a significant influence on growth parameters,  namely plant height, leaf length and width per week. However, other variables, such as the number of leaf and spinach harvest did not show significant efect. This showed that coffee skin compost tends to affect spinach growth more than corn in the intercropping system. Although the effect on corn was not statistically significant, the highest mean values ​​were observed at P3 (5.2 tons/ha) and P4 (6 tons/ha) treatments  in corn and spinach intercropping.

Abstract

Bats are recognized as ecologically important mammals and potential natural reservoirs of zoonotic pathogens, including coronaviruses. However, baseline ecological information on bat diversity in human-influenced landscapes of Lampung, Indonesia, remains limited. This study aimed to conduct initial surveillance of bat diversity in selected urban and rural habitats in Lampung and to provide an ecological basis for assessing potential zoonotic risk contexts. Bat sampling was conducted using mist net trapping in four locations representing urban and rural landscapes, followed by morphological and morphometric identification. A total of 37 individuals representing five bat species were recorded, comprising four fruit-eating species, Cynopterus brachyotis, Cynopterus sphinx, Cynopterus horsfieldii, and Cynopterus titthaecheilus, and one insectivorous species, Scotophilus kuhlii. The predominance of C. brachyotis across all sites indicates broad ecological adaptability, particularly in human-modified environments. Rural habitats supported greater species representation than urban sites, suggesting the influence of habitat heterogeneity on bat assemblages. Morphometric and reproductive observations further supported species discrimination and ecological interpretation. Although this study did not assess pathogen presence directly, the occurrence of bats at human–wildlife interfaces provides important baseline information for future surveillance related to reservoir hosts and zoonotic disease risks. These findings contribute to understanding bat diversity in Lampung and support further ecological and epidemiological investigations.

Abstract

Microalgal omega-3 fatty acids have gained considerable attention as sustainable alternatives to fish-derived lipids due to environmental constraints, contamination risks, and increasing demand for nutraceutical products. However, the rapid growth of this field has led to a fragmented body of literature, necessitating a systematic evaluation of research trends and thematic developments. This study aims to examine the evolution, collaboration patterns, and thematic structure of microalgal omega-3 research using a bibliometric approach. Bibliographic data were retrieved from the Scopus database for the period 2010–2025 using relevant keywords, yielding 1,050 publications after screening. The dataset was analyzed using Biblioshiny and VOSviewer to assess publication trends, country contributions, journal distribution, author networks, and keyword co-occurrence. The results demonstrate a marked increase in publication output, particularly after 2017, indicating growing interest in sustainable lipid sources and functional food applications. India, China, and the United States emerged as leading contributors, supported by strong international collaboration. Thematic analysis identified four principal clusters: microalgal biotechnology and lipid production, nutritional and pharmaceutical applications, metabolic and biosynthetic pathways, and food and feed utilization. Therefore, this study highlights the rapid expansion and multidisciplinary nature of microalgal omega-3 research while providing insights to support future scientific development and innovation.

Abstract

Hostplant availability is a key factor influencing butterfly distribution, particularly in urban environments with limited ecological resources. This study aimed to examine the colonization, oviposition behavior, and pre-adult development of Pachliopta antiphus antiphus following the introduction of its host plant Aristolochia tagala in a residential area in Palembang, Indonesia. A direct observation method was applied to monitor butterfly presence, egg-laying activity, and development from egg to adult stage. All observed individuals  (total of 12 eggs successfully developed into adults. Eggs were laid singly, primarily on young leaves. Larval development consisted of four instars, with increasing body size and feeding rate at each stage. The duration from egg to adult emergence fell within the normal developmental range reported for the genus. This finding highlights the importance of hostplant presence in supporting butterfly persistence and suggests a nested pattern of species occurrence within urban landscapes.

Abstract

Populations of the Siamang (Symphalangus syndactylus) are declining due to habitat loss and illegal exploitation, highlighting the need for effective conservation strategies. Rehabilitation and reintroduction programs are important efforts, but their success depends on the behavioral readiness of individuals. Therefore, this study aimed to assess activity budgets, vertical space utilization, and behavioral responses to environmental enrichment in a rehabilitated siamang candidate for release. Behavioral observations were conducted using a scan sampling method during two periods, before and after the implementation of environmental enrichment. The enrichment consisted of woven palm leaf devices filled with fruits and vegetables placed at elevated positions to stimulate natural foraging and locomotion behaviors. Observed behaviors included feeding, locomotion, resting, grooming, social interaction, and enclosure strata use, which were analyzed quantitatively based on frequency and percentage. The results showed that environmental enrichment influenced behavioral patterns and activity distribution. Active behaviors increased from 57.67% before enrichment to 72.6% after enrichment, while resting behavior decreased from 42.33% to 27.4%. Social interaction increased notably, and locomotion remained a dominant activity. Vertical space utilization also shifted, with the use of the upper stratum increasing from 66.0% to 86.1%, while the lower stratum was no longer utilized after enrichment. In conclusion, environmental enrichment enhances behavioral competence in rehabilitated siamangs by promoting active behaviors and encouraging the use of upper canopy space, supporting their readiness for release.
