<![CDATA[Abstract. Lake Sentani is located in Jayapura Regency, Papua Province with an area 9,360 ha and 70-90 meters above sea level. The lake directly adjacent to Cycloops Mountains Nature Reserve, obtaining supplies of about 34 springs. The aim of the research was to describes the lake bathymetry as a basic information for the utilization. The function are as habitat place for many species, water resources, fisheries, transport and tourism. Morphometry and bathymetry of the lake is very important for the sustainable management of the lake functions as a topography and relief lakes that have different extreme depths. Making the bathymetry of the lake is done with the acoustic method. Recording data using Garmin GPSmap 76CSx and Garmin Echo 100 Fishfinder. The result of the research showed that the depth of Lake Sentani with 9 variation at the different location, in generally range 15-23 m. Meanwhile, the waters of the deepest lake located in the eastern part of the lake is more than 70 m and the lowest depths of 0-7 m are in the middle of the Sentani area.Keywords: bathymetry; morphometry; acoustic method; Garmin Echo 100 Fishfinder; Lake SentaniAbstrak. Danau Sentani terletak di Kabupaten Jayapura, Provinsi Papua dengan luas 9.360 ha dan ketinggian 70–90 m dpl. Danau ini berbatasan langsung dengan Cagar Alam Pegunungan Cycloops dan memperoleh suplai dari sekitar 34 sumber mata air. Tujuan penelitian ini adalah menggambarkan batimetri danau sebagai informasi dasar pemanfaatan danau.

<![CDATA[Phytoplankton is an autotrophic organism that produce its own food through the process of photosynthesis with the help of sunlight which forms the basis of water productivity to be utilized for trophic organisms above. In freshwater, river plankton are categorized as potamoplankton. Rivers are a dominant freshwater ecosystem and have a more stable morphology than other freshwaters. Changes in land function is triggered by an increase in human population, an increase in the number of residential areas and industrial activities that discharge untreated waste into the river. Because of the importance of phytoplankton for life, it is necessary to conduct research on the Comparison of Phytoplankton Composition and Abundance Based on Different Land Uses in the Cisadane River, Tangerang Regency. In this study, sampling was carried out using a purposive sampling method by measuring parameters such as pH, temperature, and water transparency. Identification of phytoplankton composition and abundance was carried out using the Sedgwick Rafter Counting Cell (SRCC) using the sweep method. The results of this study obtained 23 phytoplankton genera from 6 classes consisting of: Bacillaryophyceae, Cyanophyceae, Chlorophyceae, Conjugatophyceae, Trebouxiophyceae, and Zygnematophyceae. Phytoplankton abundance was 185-490 Ind/L with the highest abundance in both areas are Bacillaryopiceae and Navicula. The diversity index was 1.307-2.124 and the dominance index was 0.201-0.461. Water quality parameters that affect the composition and abundance of phytoplankton are water-transparency, pH, and water temperature. The fertility level of the Cisadane River waters has an oligotrophic fertility level.]]>

<![CDATA[Agroforestry-integrated community forests foster greater plant diversity compared to conventional agriculture, potentially offering significant ecological and societal benefits. However, the specific contribution of diverse floor vegetation within these forests to carbon cycling remains understudied. This study addresses this knowledge gap by comprehensively analyzing the floristic composition and carbon storage potential of floor vegetation in tropical community forests. Using a stratified random sampling design with quadrats to ensure representative data collection across various locations in Ciamis Regency, West Java, Indonesia, we identified 296 plant species belonging to 89 families. Our analysis revealed that the understory vegetation exhibits moderate species diversity and stores carbon ranging from 0.107 to 0.238 Mg C ha⁻¹, with an average sequestration potential of 0.730 Mg C ha⁻¹. These findings suggest that community forests harbor diverse floor vegetation communities with significant carbon storage and sequestration potential, providing valuable insights for environmentally sustainable community forest management and contributing to broader efforts towards climate change mitigation.]]>

<![CDATA[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.]]>

<![CDATA[Water is a basic necessity for living things. The catchment area (DTA) is very important to be conserved to maintain water availability and prevent the exploitation of springs. Studies on water and land conservation in Beji Village, Ngawen Sub-district are still very limited, especially DTA outside Wonosadi indigenous forest area. This study aims to study structure and composition of tree vegetation in DTA Wonosadi, Gunungkidul. Determination of DTA analyzed by using ArcGIS 10.2 with overlay of Hydrogeology Map, Indonesian Earth Map (RBI), and QuickBird Image. Analysis of vegetation in the analysis using Microsoft Excel software. Tree vegetation analysis used 10 m x 10 m square plot (40 plots) on each vegetation density class of DTA. The results showed that area of DTA Wonosadi was 23.300.924 m2. S. macrophylla King has highest density overall. S. macrophylla King, Tectona grandis L and Tectona grandis L has the highest Importance Value Index (IVI) of each vegetation class. This research concluded that tree vegetation structure in DTA Wonosadi is dominated by poles growth form. Tectona grandis L. is species that has the highest INP, which potentially affect ground water availability and reduce water discharge.]]>

<![CDATA[Rafflesia patma Blume is a plant endemic to Pangandaran, West Java, which is protected because of its rare status. This study aims to study the composition of the floristic vegetation that supports the life of R. patma in the Pananjung Pangandaran Nature Reserve, West Java. The research was conducted using a survey method with a purposive sampling technique and sampling using quadrat. The data obtained were then analyzed using the Importance Value Index (IVI), Shannon-Wiener index, and Evenness index. The results showed that R. patma in the Pananjung Pangandaran Nature Reserve lived as a parasite on the roots and stems of Tetrastigma leucostaphylum. The floristic composition of the habitat of R. patma in the Pananjung Pangandaran Nature Reserve, West Java, consisted of 251 individuals divided into 28 species. The plant species with the highest Importance Value Index (IVI) were Syzygium antisepticum, Stephania capitata, Casearia sp., and Buchanania arborescens for the sapling category, as well as Syzygium antisepticum and Vitex pubescens for the tree category. The condition of the vegetation around the habitat of R. patma is quite dense with the diversity index values obtained belonging to the moderate level of diversity. The highest diversity index at the sapling level was found at the Cilegon location with an H' value of 2.14 and the highest diversity index at the tree level was found at the Gua Parat location with an H' value of 1.5.]]>
