Abstract

Macrozoobentos are animals that live permanently in sediments at the bottom of the water, both on soft and hard substrate conditions. Macrozoobenthos contribute greatly to the function of aquatic ecosystems and play important roles such as mineralization processes in sediments and organic material cycles and play a role in transferring energy through the food chain. Based on the results of research conducted on the Lantahiwo River, Kotawo Village, West Kulisusu District, the species richness of macrozoobenthos found in the Lantahiwo River was varied where the number of individuals obtained from station 1 (upstream) was 20 individuals. At station 2 (middle of the river) there were 60 individuals, while at station 3 (downstream) there were 14 individuals. The river is a form of aquatic ecosystem that has an important role in the hydrological cycle and functions as a catchment area for the surrounding area. So that the condition of a river is strongly influenced by the characteristics of the surrounding environment. The sampling point includes looking at the considerations made in the field and sampling at stations 1, 2 and 3 is carried out in stages, first in the upstream, middle and downstream parts of the river then observations are made with several parameters that are considered important by researchers as key parameters that represent and describes the waters of the Lantahiwo River. This research was conducted from March to April 2020 in Kotawo Village, Kulisusu Barat District, North Buton Regency. Based on the results of identification, where the types of macrozoobenthos found in the Lantahiwo River at stations 1 to 3 consist of 2 families and 2 classes, namely; types of family Gerridae from class Bivalvia, species from family Thiaridae from class Gastropods, species from family Thiaridae from class Macrozoobentos were found at each station.

Abstract

This research was conducted to identify the potential level of earthquake damage in Kadia District, Kendari City. The potential level of damage is known based on the seismic vulnerability index parameter. The data used is microtremor data obtained from the results of the frequency filtering process of ground vibration data using a Band Pass Filter type with a frequency range of 1.00 to 25.00 Hz. While the ground vibration data was obtained from the results of direct measurements in the field at 16 measurement points using 1 set of portable seismograph TDL 303S. Furthermore, the data is processed using the Horizontal to Vertical Spectral Ratio (HVSR) method to produce the dominant frequency of the soil and the amplification factor used to calculate the seismic vulnerability index. From the results of data processing carried out scientifically in Kadia District, Kendari City, a seismic vulnerability index value was obtained with values ranging from 0.761 to 5.292 /cm. Based on the results of mapping of the potential level of earthquake damage obtained from the results of the seismic vulnerability index value, it shows that Kadia District, Kendari City has a low to moderate potential for damage due to earthquakes. Low zones with seismic vulnerability index values ​​< 3 are scattered in Kadia, Bende, Anaiwoi, and Wowawanggu Villages. Moderate zones with seismic vulnerability index values ​​< 3 to 6 are scattered in Kadia, Pondambea, and Bende Villages.

Abstract

This research on Ground Shear Strain (GSS) was carried out to determine the potential for ground movements in Kadia District, Kendari City. In its implementation, GSS is processed using microtremor data from measurements in the field. GSS is the result of multiplying the Seismic Vulnerability Index (Kg) and the basement Peak Ground Acceleration (PGA). Microtremor data were taken at 16 measurement points with a distance between measurement points of 400 to 600 m. The microtremor data were then analyzed using the HVSR (Horizontal to Vertical Spectral Ratio) method available in Geopsy 3.3.6 software to obtain predominant frequency values (f­o) and amplification factors (Ao). These two parameters are used to calculate the Kg value. The PGA value is determined using the Fukushima and Tanaka empirical formula using earthquake data with a depth of ≤ 50 km and surface magnitude (MS) ≥ 5 SR. The research results show that the GSS values in Kadia District, Kendari City ranges from 1.1768x10-4 to 6.5436x10-4. Based on the results of ground movement analysis, it is known that Kadia District, Kendari City, has the potential to experience cracks or land subsidence if an earthquake occurs with elasto-plastic soil dynamics. Apart from that, it is also known that the Kadia District area of Kendari City is not prone to landslides and liquefaction because g < 10-2.

Abstract. Manan A, Sudia LB, Hasani UO, Kete SCR, Gandri L, Yasin A, Agusrinal, Isabela. 2025. Diversity, carbon stock and economic value of the mangrove ecosystem in Wakatobi Biosphere Reserve, Indonesia. Biodiversitas 26: 1095-1104. Mangrove ecosystems significantly contribute to climate change mitigation through the absorption and storage of carbon. This research evaluates the diversity, carbon stock, and economic valuation of mangrove ecosystems within the Wakatobi Biosphere Reserve. Data collection occurred at 11 stations distributed among four primary islands: Kaledupa, Wangi-Wangi, Tomia, and Binongko. Diameter at Breast Height (DBH) measurements were utilized to estimate biomass and carbon storage, employing species-specific allometric equations. Economic valuation utilized carbon trading data from the Indonesia Stock Exchange (IDX Carbon) as of 3 January 2025, alongside the Social Cost of Carbon (SCC) and Voluntary Market (VM) prices. The mangrove ecosystem of the Wakatobi Biosphere Reserve covers an area of 10,994 hectares and is in excellent ecological condition. The Shannon-Wiener Diversity Index values for tree and pole strata demonstrate moderate diversity (1-3), with Kaledupa and Binongko classified as moderate, whereas Wangi-Wangi and Tomia are categorized as low (&lt;1). The evenness score indicates a high classification for tree strata (&gt;0,6), with the exception of Wangi-Wangi, which is classified as medium (0,4-0,6). Wangi-Wangi Island is classified as low for splinter strata (&lt;0,4), whereas Tomia, Kaledupa, and Binongko Islands are classified as medium. The composition of mangrove species differed across islands, with Sonneratia alba, Rhizophora mucronata, Bruguiera gymnorrhiza, and Ceriops tagal identified as the most prevalent species and significant contributors to carbon sequestration. The total carbon stock was estimated at 329,82.06 tons, with Kaledupa Island exhibiting the highest stock at 317,226.51 tons, while Binongko Island recorded the lowest at 2,053.8 tons. The economic valuation of carbon storage indicates significant potential: IDR 18,763,377,420 or USD 1,159,307 (IDX Carbon), IDR 266,390,582,055 or USD 16,459,103 (SCC), and IDR 43,155,274,293 or USD 2,666,375 (VM), underscoring the financial importance of mangrove conservation. This signifies a potential for revenue generation in the Wakatobi region, offering a hopeful prospect for the future. This study highlights the ecological and economic significance of mangroves and establishes a basis for sustainable conservation and management strategies aimed at improving the resilience of the Wakatobi Biosphere Reserve.

Abstract

Flood frequency in Kendari City has sharply increased, emphasizing need for community-based mitigation strategies. However, studies examining the contributions of structural and non-structural flood mitigation at community level remain limited, particularly in flood-prone areas such as Lepo-Lepo. This study identifies and analyzes the contributions of structural and non-structural flood mitigation efforts in Lepo-Lepo Village, Baruga District, Kendari City. Research from June to July 2021 employed observation, interviews, literature studies, and document analysis, with data analyzed descriptive and qualitatively. Lepo-Lepo Village experienced five floods between 2013 and 2021. The 2013 and 2017 floods were the most severe, with water levels reaching 3–4 meters. In 2018, floods reached 2 meters and lasted several days; in 2019, 1–2 meters for five days; and in 2021, 1 meter for two days. These floods were triggered by high-intensity rainfall and overflow of the Wanggu River, resulting in casualties, infrastructure damage, and economic losses. To reduce flood risk, integrated structural and non-structural measures were implemented, including embankments, drainage improvements, retention ponds, mosque siren warnings, weather monitoring, evacuation training, and Disaster Preparedness Groups (KSB). These measures improved flood control, strengthened early warning systems, and enhanced community preparedness and through community participation and institutional coordination.
