Indonesian Journal of Tropical Biology (IJTB) is a scientific journal that accommodates the results of basic and applied research in the field of tropical biology. The focus of this journal covers various aspects of biology such as ecology, biodiversity, conservation of biological resources, biotechnology, physiology, genetics, zoology, botany, and microbiology, especially those related to tropical ecosystems. IJTB aims to be a scientific communication forum for historians, researchers, and practitioners in developing science and its application to support tropical ecosystems and biological resources. Published manuscripts can be research results and results that have used scientific methodology standards. Therefore, the Indonesian Journal of Tropical Biology (IJTB) is a peer-reviewed journal published by the Siti Widhatul Faefa Foundation, which is published three times a year (January-April, May-August, September-December) in online and print versions.

Abstract

Butterflies (order Lepidoptera) are a group of insects that have an important role in ecosystems as pollinators, part of the food chain, and bioindicators of environmental quality. The diversity of butterflies also contributes to the aesthetic value and ecotourism potential of an area. This study aims to identify the types of butterflies and analyze their diversity and abundance in the Kelantangan Nature Tourism Park (TWA), West Lombok, West Nusa Tenggara. The survey was conducted using the visual transect method along the observation path at the active time of the butterflies, namely morning and noon. Data were analyzed using the Shannon-Wiener diversity index (H'), the Simpson dominance index (D), and the uniformity index (E). The results of the study show that the TWA Kerandangan area has a moderate to high level of butterfly diversity, with several species classified as endemic and indicators of habitat quality. The existence of different types of host plants and natural vegetation supports the diversity of species found. These findings show the importance of the role of the TWA Kerandangan area as an insect habitat and support the urgency of sustainable conservation management. In addition, the results of this research can be used as a basis for the development of biodiversity-based educational ecotourism in the region.

Abstract

Vegetables, as a source of plant-based protein, play a significant role in a healthy and sustainable diet. Several vegetables from the Fabaceae, Brassicaceae, and Amaranthaceae families are known to contain high levels of protein, making them viable alternatives to animal-based protein. This study aims to examine the potential of vegetables as alternative protein sources in supporting food security and sustainability. A literature review was conducted to analyze the protein content in various vegetables based on scientific literature from indexed journals and trusted organizations. The analysis was performed descriptively, comparing the protein content of vegetables based on their type, growth phase, and growing environment, while also identifying the biological roles of protein in plants. The results indicate that protein is a food substance made up of amino acids, which functions to build and regulate the body. Of the 20 amino acids, 8 are essential for adults and 10 for growing children. High-protein vegetables include spinach (Amaranthus sp.) with 3.5 g of protein per 100 g, broccoli (Brassica oleracea) 2.8 g, soybeans (Glycine max) 18.2 g, peanuts (Arachis hypogaea) 21 g, potatoes (Solanum tuberosum) 2%, and edamame (Glycine max) 18.5 g per 155 g. These vegetables are rich in protein, vitamins, and minerals essential for the body and offer health benefits such as improved stamina, support for bone health, and reduced risk of certain diseases. The study concludes that vegetables and legumes with high protein content can serve as an optimal alternative source of nutrition to support a healthy diet.

Abstract

Macroalgae play a crucial ecological role in coastal ecosystems, particularly in tropical and subtropical marine environments. This study aims to review the evolution, global distribution, and ecological functions of macroalgae through a systematic literature review approach. Scientific articles from the last ten years were selected from databases such as Scopus, ScienceDirect, and Web of Science, with a focus on macroalgae diversity, taxonomy, bioactive compounds, and environmental services. Results show that macroalgae have existed since the Proterozoic era and have evolved into morphologically and genetically diverse lineages. Distribution patterns vary significantly between tropical and subtropical zones, influenced by environmental factors such as temperature, salinity, and light intensity. In mangrove and coral reef ecosystems, macroalgae demonstrate adaptive capacity and act as habitat formers, carbon sinks, and bioindicators of ecosystem health. Several genera, including Sargassum, Padina, and Caloglossa, exhibit resilience and high ecological value. Furthermore, macroalgae are rich in bioactive compounds with potential applications in pharmaceuticals, cosmetics, and biofuels. Their high biomass productivity and carbon sequestration ability, comparable to seagrasses and mangroves, highlight their strategic role in blue carbon initiatives. However, excessive macroalgae blooms, particularly in the Atlantic Sargassum belt, raise environmental and socioeconomic concerns. This review emphasizes the need for integrated coastal management strategies to optimize the ecological and economic benefits of macroalgae sustainably.

Abstract

The COVID-19 pandemic has significantly impacted food security and the biological vulnerability of farming households, especially in rural areas heavily dependent on agriculture. This study aims to analyze the effects of the COVID-19 pandemic on the food security of farming households in Pringgasela District, East Lombok, and its relation to the biological vulnerability of farmer families. A descriptive quantitative and qualitative method was used, with data collection techniques including interviews, questionnaires, and documentation. The study sample consisted of 30 farming households directly affected by the pandemic. The results show that the pandemic disrupted food availability (73.33% of respondents) and access to food (86.67% of respondents) due to social restrictions and distribution disruptions. The majority of respondents (90%) reported food shortages and difficulties in meeting nutritional needs. Socio-economic factors such as low income, low education, and dependence on small-scale farming exacerbated vulnerability to malnutrition and health issues. Major challenges included decreased food production, limited access to quality food, and food price instability. These findings highlight the importance of interventions in the form of social and economic support to improve food security and enhance the quality of life for farming households during a crisis.

Abstract

Tuberculosis is one of the deadly infectious diseases worldwide. It is caused by Mycobacterium tuberculosis infection. The cases of tuberculosis in 2022 were reported to be 824,000 with an annual death toll of 93,000. Tuberculosis is a disease caused by long-term treatment and falls under the ICD-10 code 16.2 for national health insurance coverage. The aim of this research is to determine the cost of illness due to tuberculosis from a health perspective and to determine the variables associated with the cost of illness due to tuberculosis at RSUD dr. Soeselo Slawi in 2022. This research method uses observational with a cross sectional research design on 82 patient data, descriptive analysis methods to determine cost estimates and statistical methods to determine the factors that influence the total cost of illness for tuberculosis patients. Based on the research, it shows that the cost of service is the highest cost component compared to other cost components. The average cost of supporting examinations is Rp. 753,827.00; service fee of Rp. 2,133,809.00; and pharmacy costs Rp. 1,873,449.00. The average cost of tuberculosis illness from a healthcare perspective is Rp. 4,761,085.00. The largest component of the illness costs is the service cost. The variables significantly associated with a Sig. (2-tailed) value ˂ 0.05 are the ward class, length of stay, diagnostic test costs, service costs, and pharmacy costs with respect to the total illness costs.
