Abstract

Segara Anakan Mangrove Forest in Cilacap is one of the most extensive mangrove forests on the southern coast of Java Island. This study aims to determine the level of herbivory and environmental conditions. The sampling technique used was purposive random sampling, which considered the different characteristics of the vegetation. Sonneratia caseolaris dominated Station 1, while Station 2 was more diverse, including Avicennia marina, Avicennia alba, Rhizophora mucronata, Sonneratia caseolaris, and Aegiceras corniculatum. Each station is spread over three points, each with five sampling plots, representing the distribution and zonal homogeneity of carrying capacity. The research was conducted in May, August, and November 2023, based on the different temporal seasons in Indonesia. The results showed biotic factors from herbivory activity and abiotic factors such as the hydrological cycle caused mangrove leaf damage. The class of leaf damage caused by herbivory at all observation stations was mainly in class I (<2.5%). The most leaf damage was found in old leaves, which is related to the optimal photosynthesis process producing carbohydrates as a food source for herbivores. Additionally, tannin content in the leaves plays a role in protection from excessive UV radiation during the dry season. This condition indicates that Segara Anakan mangrove forest is still in good condition. PCA analysis results show that mangrove leaf damage is closely related to the age of the leaves.

Abstract

ARTICLE HIGLIGHTS- Nickel mining activities significantly impacted the ecological integrity of the Pomalaa coastal area in Southeast Sulawesi, particularly in the mangrove ecosystem.- The exposure of overburden waste in the mangrove ecosystem has led to the loss of important gastropod species and a decline in population of surviving species- The low population of gastropod species in nickel mining impact areas indicates extensive environmental damage caused by these activities.ABSTRACTGastropod resources in the Dawi-Dawi mangrove ecosystem, Southeast Sulawesi are greatly influenced by the input of overburden waste (sediment) from nickel mining activities. This condition has been going on for the last 2 decades and has degraded the habitat and structure of the gastropod community. The upstream connectivity (the existing nickel mining area) and the Dawi-Dawi River estuary mean that the mangrove forest (estuary) in this area is continuously affected by (massive) overburden runoff. This research was carried out in June-August in the mangrove ecosystem of Dawi-Dawi Village, Southeast Sulawesi Province. This research aims to determine the existing condition of mangrove gastropods affected by overburden. This research began by conducting initial observations in the field, to identify mangrove ecosystems affected by overburden. research stations were determined using a purposive sampling technique (targeted) and sampling gastropods using a simple random sampling method. The ecological index of the mangrove gastropod community affected by overburden shows a tendency for a medium diversity index (H'=1.81), low species richness (R=1.42), high evenness (E=1.12), and no dominance of certain species (C=0.19). The gastropod species found are typical types that make up the mangrove fauna, namely Terebralia sulcata, Terebralia palustris, Faunus ater, Telescopium telescopium, Hebra nigra, and several taxa (genus) of climbing Littoraria snails (periwinkle) which are found in the roots, stems and leaves of mangroves. The abundance of gastropods obtained was also very low, namely around 0-12 Ind./m2. At some points (rarely) schools of small snails of the type T. sulcata (5-21 Ind./m2) are sometimes found. This research shows de facto that overburden waste eliminates (survival) or reduces the diversity and richness of gastropod species (ecological index) in the mangrove ecosystem of Dawi-Dawi.

Abstract

Western Segara Anakan Lagoon (WSAL) is a semi-enclosed lagoon located in the Cilacap, Central Java Province, Indonesia which has two outlets called pelawangan. West Pelawangan is an open channel from WSAL and the Indian Ocean, which has vast sediment input. It impacts the sediment deposits and delta formations in WSAL. This research aimed to determine the sediment characteristics deposited in the WSAL specifically in the delta formation area, and the mean size of sediments (D50), sorting, and skewness. The research used the survey method while data collected were sediment-bed, bathymetry, and satellite imagery Sentinel 2A with the ebb-tide condition. Sediment was analyzed by sieve and gravimetry and interpreted as a Ternary diagram, D50, sortation, skewness, and fraction percentage spreading map. Satellite imagery Sentinel 2A was searched by the ebb-tide condition. Shorelines and delta was extracted by the Normalized Different Water Index. Bathymetry built from depth points data 2018. The results of the Ternary diagrams analysis were the Citanduy River had a sand grain size, the Pelawangan Barat Waters (PBW) were dominated by sand and the lagoon was dominated by a fine grain size and silt. The result of sediment D50, sortation, and skewness in the Citanduy River and the PBW were dominated by sand, and the lagoon was dominated by fine sediment: silt, and clay grain size. The sediment fractions were sorted very well; skewness was dominated by the fine skewed (positive skewed). The delta formation in the lagoon covers a large area, presumably due to the consolidation of the fine sediment.Keywords: Sediment Characteristics, Ebb-Tidal Delta, Western Segara Anakan Lagoon

Abstract

The Karimunjawa National Park area has various coastal resources and ecosystems, such as mangrove forests, seagrass, and coral reefs, which provide a habitat for several vital organisms. The presence of natural and human factors in coastal areas causes environmental degradation. Changes in environmental conditions, increasing population, and land requirements in Karimunjawa National Park can have negative impacts if not appropriately managed. Therefore, coastal management strategies are needed to maintain sustainability and prevent the extinction of coastal resources. The research locations are Karimunjawa Island and Kemujan Island. This research aimed to develop a coastal management strategy based on changes in the shoreline of Karimunjawa Island and Kemujan Island. The SWOT (Strengths, Weaknesses, Opportunities, Threats) analysis model was used to identify coastal management strategies through the most effective priority scale. The research results showed that in 2008-2023, the average erosion on Karimunjawa Island was -11.41 m or -0.75 m/year, and accretion was 13.30 m or 0.87 m/year, while the average erosion on the island rainfall was -13.74 m or -0.90 m/year and accretion is 13.30 m or 1.07 m/year. Management strategies that can be implemented are (1) forming a board or committee; (2) conducting outreach and education activities; (3) identifying critical areas; (4) developing protection and utilization programs; (5) conducting research; (6) monitoring; (7) formulating policies.

Abstract

Mangrove litter is a critical component of the nutrient cycle, reflecting soil fertility and water quality within the mangrove ecosystem. This study investigates the dynamics of litter productivity in the Segara Anakan mangrove forest in Cilacap. The study area is divided into two locations with three points, with five litter traps installed at each point. Sonneratia caseolaris dominates vegetation characteristics at Station 1, while Station 2 has more diverse vegetation, including Sonneratia caseolaris, Aegiceras corniculatum, Acanthus ilicifolius, Derris trifoliata, Rhizophora mucronata, Avicennia alba, and Avicennia marina. Sampling follows seasonal changes in Indonesia, covering June 2023 to March 2024. The primary data for this study include aboveground litterfall production, estimated using litter traps, and the litter layer on the forest floor collected through soil transects. Secondary data comprise weather measurements, including air temperature, rainfall, wind speed, and humidity. Litterfall and litter layer were collected four times: June (dry season), September (transition from dry to rainy season), December (rainy season), and March (transition from rainy to dry season). The results indicate a total litter productivity of 18.99 tonnes ha-1 yr-1. The lowest litter production was observed in September, while the highest was in March. Leaf litter contributed the most, accounting for 71.49%, followed by twigs at 19.19%, flowers/fruits at 8.31%, stipules at 0.62%, and the lowest portion from other unidentified materials at 0.39%. Litter productivity shows a strong correlation (0.99) with rainfall. The main factors influencing litter productivity include environmental factors, primarily rainfall, and physiological factors, such as flowering and fruiting phenology.
