Abstract

Plankton are organisms that live floating in water bodies and move with the current. Plankton is a clue organism that can be used as a bioindicator because it is sensitive to environmental changes. The purpose of this study was to explore the limnological aspects of plankton distribution and diversity as bioindicators of water quality. In this study, 29 species of phytoplankton and 20 species of zooplankton were obtained, dominated by Nitzschia sp. and Asplanchna sp. The abundance index showed that the abundance of phytoplankton was 19386.67 ind/L and zooplankton was 5.33 ind/L. Water status based on phytoplankton diversity index with a value of 0.28-1.00 is categorized as low diversity and zooplankton diversity with a value of 0.78-1.97 is categorized as moderate diversity.

Abstract

The Javan surili (Presbytis comata), a keystone species in the tropical rainforest ecosystem of Java Island, is facing serious threats from deforestation, hunting, and habitat fragmentation. As an endemic species with a highly restricted, particularly on the island of Java, research on the Javan surili remains considerably limited. Hence, its geographical location and distribution patterns are still not clearly understood. Our literature review aims to determine the current status of the Javan surili and the factors influencing its population decline, as well as to evaluate the effectiveness of various conservation strategies that have been implemented. These findings highlight the importance of a multidisciplinary approach in Javan surili conservation efforts and provide policy recommendations to improve the success of species conservation, especially in its native habitat. Immediate conservation efforts and attention from the primatologist, relevant authorities, and stakeholders are needed to prevent the localized extinction of Javan surili.

Abstract

Macrocephalon maleo is an endemic bird species of Sulawesi that selects nesting sites based on specific environmental conditions, particularly optimal soil temperature, moisture, water content, soil weight, and texture (including clay, dust, and sand composition). However, studies examining the relationship between soil physical characteristics and microclimatic factors across multiple nesting sites remain limited. This study aims to analyze the distribution patterns and the correlation of ecological characteristics that influence the existence of maleo in Central Sulawesi. The research was conducted from February 2024 to March 2025 at seven locations with a total of 23 coordinate points, including nesting grounds near geothermal sources (Saluki, Lore Lindu National Park), coastal areas (Taima, Moilong, Batui, Ampana, and Balingara), and a riverbank area (Bukit Jaya). Field observations were carried out for 10 days at each location, during which 197 maleo birds were recorded. Maleo distribution patterns were analyzed using the Morisita Index, while the relationships between ecological factors and maleo presence were assessed using Pearson correlation analysis. The Morisita Index indicates a clumped distribution pattern, with values ranging from 2.0 to 5.0. The average sand temperatures recorded were 33.9°C in the geothermal area (Saluki TNLL); 35.0°C, 34.4°C, 35.4°C, 33.13°C, and 32.9°C in the coastal areas (Taima, Moilong, Batui, Ampana, and Balingara), and 36.1°C in the riverbank area (Bukit Jaya). The results indicate that soil-related ecological factors, particularly water content, soil texture, and sand weight, had a stronger influence on maleo presence than ambient microclimatic variables such as air temperature, humidity, wind speed, and light intensity. Soil texture influences water retention, aeration, heat absorption, and soil consistency. Sandy soils tend to absorb and release heat efficiently, thereby creating suitable incubation conditions for maleo eggs in natural nesting habitats.
