Abstract

The cattle egret (Bubulcus ibis) utilizing landfill sites for foraging is not a new or rare phenomenon. However, to date, there is no scientific data on the presence of cattle egrets in landfill areas on a national scale. This study aimed to determine the abundance dynamics of cattle egrets at the Jatibarang landfill. Data collection on individual count dynamics was carried out using the Concentration Count method. Initially, this method involved identifying strategic areas to facilitate counting individual birds in each Active Zone. Bird censuses were conducted from 06:00 to 18:00 WIB using hourly photographic documentation. Data on the dynamics of cattle egret abundance in each Active Zone were tabulated using Microsoft Excel 2016, and graphs were produced to show the average number of individuals during the study. The results showed that the abundance dynamics varied among Active Zones, influenced by the status of waste disposal activities, which affected the availability of abundant food. The distribution patterns and utilization levels of cattle egrets in the three Active Zones differed due to variations in waste conditions, influencing the number and types of insects (larvae and adults). Active Zone 1 was intensively used by cattle egrets, with numbers reaching between 140 and 1505 individuals.

Abstract

Marine Science Techno Park (MSTP) is an area located in the Teluk Awur Beach region, Jepara Regency, Central Java. This area features a rehabilitated mangrove ecosystem that has been established for approximately 20 years. This research aims to study the mangrove vegetation structure, including diversity, composition, evenness index, Importance Value Index (IVI), and assess the regeneration of true mangroves in the Marine Science Techno Park (MSTP) area in Teluk Awur, Jepara, Central Java. The study was conducted at 3 stations: the mangrove track area (Station 1), riverbank area (Station 2), and coastal area (Station 3). The research identified 20 mangrove species (5 major mangroves, 4 minor mangroves, and 11 associated mangroves) belonging to 15 families. The species diversity index (H') ranged from 1.51 to 1.68, indicating a moderate category, while the evenness index indicates relatively even evenness ranging between (0.63 – 0.69), indicating relatively even communities and stable populations. The highest INP at station 1 (mangrove track) is Rhizophora mucronata Lamk (INP 163.58%), at station 2 (riverbank) is Bruguiera cylindrica (L) BI (INP 150.52%). At station 3 (coastline) the highest INP is Rhizophora mucronata Lamk (161.07%). The regeneration status of true mangroves in the MSTP area, categorized as good, includes Xylocarpus granatum Koen, Bruguiera cylindrica (L) BI, Ceriops tagal (Perr.) C.B. Rob, Rhizophora apiculata BI, and Rhizophora mucronata Lamk, while poor regeneration was observed in Nypa fruticans Wurmb, Lumnitzera racemosa Willd, Excoecaria agallocha L, and Aegiceras corniculatum (L.) Blanco.

Abstract

The Parijoto plant (Medinilla sp.) is an iconic and culturally significant species in Colo, Kudus, where many local farmers cultivate it. Based on preliminary interviews with farmers, several insect pests such as grasshopper and caterpillars have been reported to cause damage to the plants. The study aimed to identify potential impact of insect pests on Parijoto plant, asses their diversity and abundance, and analyze environmental factors that may influence their presence. The research was conducted in November 2022 using a survey method with three sampling periods. Insect collection was carried out using insect net and aspirators, while sample bottles were used for temporary storage before identification. Environmental factors, including light intensity, air humidity, soil humidity, and soil temperature, were also measured. A total of 11 potential insect pest species were identified, with the majority belonging to the orders Lepidoptera and Orthoptera. These findings provide valuable insight into the insect pests associated with Medinilla sp. in Colo, Kudus, which may help farmers develop better pest management strategies.

Abstract

The Bangka Belitung Islands Province has a mangrove ecosystem covering an area of 273,692.81 hectares. These ecosystems play a crucial role in mitigating greenhouse gas emissions through the sequestration mechanism, which involves absorbing carbon from the atmosphere and storing it in the form of biomass. Human activities around these areas, such as the flow of tailings from artisanal mining (TI), have caused damage to these ecosystems, leading to a reduction in one of the primary carbon dioxides (CO2) absorbers. This study aims to support the sustainable management of mangrove conservation areas in efforts to reduce the impact of global warming. Sampling stations were determined using purposive sampling, with the collection of substrate carbon, biomass, and carbon samples, as well as water quality parameters at Takari Beach. The results showed that the water temperature was 28°C, salinity ranged from 25 to 27 ppt, and pH ranged from 5 to 8,5. Four mangrove species were found at two stations: Rhizophora mucronata, Rhizophora apiculata, Sonneratia alba, and Lumnitzera littorea, totaling 185 trees. The mangrove biomass was measured at 27,10636 tons/ha, and the below-ground carbon stock was recorded at 12,74 tons/ha.
