Abstract

Macroinvertebrates is one of bioindicator for aquatic ecosystem. By assessing indicator species, diversity, functional groups of macroinvertebrates community, it is possible to determine water quality. Purpose of this research was to inventory and study the macroinvertebrates species diversity in Sepanjang Beach, Gunungkidul, Yogyakarta. This research was conducted on Wednesday, November 25th 2014 at Sepanjang Beach, Gunungkidul, Yogyakarta. Sampling points was determined by line transect method. At each transect, sampling with 1x1 m2 plots was done. The data obtained in this study was the result of macro-invertebrates species inventory in each sampling point and the number of individuals of each species. Data analysis was performed by calculating the Shannon-Weiner diversity index (H’). Result of this research showed that there were 63 macroinvertebrates species with 1033 number of individuals found in Sepanjang beach. Result of calculation of Shannon-Weiner diversity index (H’) showed the diversity index of macro-invertebrates in Sepanjang beach was 1.24. The diversity index showed that the diversity index of macro-invertebrates in Sepanjang beach categorized by medium diversity.

Abstract

Water is important natural resources for people and spring is one of clean natural water resources in the village. Indonesia has high rain fall, but water availability varies spacially and temporally. The change of land cover or ecosystem in spring catchment area or surroundings decreases water catchment capacity. Therefore it is necessary to conduct a study of floor vegetation contribution on rain-water infiltration. This study aims to determine the structures and the roles of floor vegetation in regards of water infiltration at various degrees of slope. This study was carried out in two times, end of the dry season from June to October 2013 and end of wet season from March to June 2014. Floor vegetation data were obtained from 6 plots (1x1m2) in each growth forms and slopes. Water infiltration were analyzed using rain simulation method in 0.5x0.5m2 plot size. Results showed that there were 18 species of 5 families and 29 species of 10 families found during the dry and wet season respectively. Rainy season triggered grass and herbaceous (Poaceae and Asteraceae) plant density from 5 to 9 times, and also shrubs density from 3 to 6 times. Based on important value analysis at slope classes, Panicum repens (34.7%), Ischaemum sp. (34.2%), Elephantopus scaber (33.5%), and Desmodium triflorum (11.9%) are grasses and herbaceous dominated all slopes during both seasons. Boerhavia difussa, Chromolaena odorata, Flemingia macrophylla, and Mimosa pudica are shrubs dominated in all slopes, especially at the steep slopes for the last 3 shrubs.  The diversity index of the floor vegetation can be categorized low. Based on the rain simulation with average rate of 67.6 mLs-1, P. repens and M. pudica, can respectively withstand water runoff for 27s and 18s and had infiltration capacity of 83.2 % and 75.9 % in the steep slope, and E. Scaber can withstand water runoff for 15s and had infiltration capacity 71.6% in the gentle slope.

Abstract

Watershed is the land area that could potentially be a source of water. The main components of watershed ecosystem composed of humans, animals, vegetation, soil, climate, and water. Watershed ecosystem components that are interconnected is going to maintain the quality of the watershed. A common problem in a watershed is the sedimentation due to large amounts of waste, landslides, and erosion. Water and soil conservation efforts in the watershed can be cultivated by maintaining the balance of watershed ecosystem components one of which is the condition of the vegetation diversity. This study intends to analyze the potential of vegetation in water and soil conservation in the watershed. In-depth study based on the results of the analysis of vegetation and 3 sub-watershed namely Keduang, Dengkeng, and Samin which is a sub-watershed in the Bengawan Solo watershed. Analysis of the condition of the vegetation around the sub-watershed Keduang, Dengkeng, and Samin shows that vegetation has an important role in maintaining the quality of the watershed. Vegetation affects the ability of soil to retain water, thus increasing soil water reserves, prevent erosion and landslides in the surrounding watershed. Vegetation potentially in favor of water and soil conservation in the watershed are shrub vegetation, grass, and other plant floor coverings.

Abstract

Long-tailed monkeys (Macaca fascicularis) are social primate animals that interact each other. Social interaction done by long-tailed monkeys give rise to different activities of individuals in the population. The purpose of this research was to study long-tailed monkeys behavior in Grojogan Sewu, Tawangmangu, Karanganyar. This research was conducted in Tuesday, November 24th 2014 in Grojogan Sewu, Tawangmangu, Karanganyar. Observational method that used in this research is focal sampling. Determination of sampling points was conducted by purposive sampling so that resulted 8 sampling points (8 individuals of long-tailed monkeys was observed). Observation was done by observing each long-tailed monkeys daily activity until 3 hours with 5 minutes intervals. Result of this research shows that the average percentage of daily activities of the observed long-tailed monkeys are: 2.27% sleeping; 20.76% inactive; 16.78% grooming; 1.99% mating; 32.85% moving; 13.37% eating; 4.97% take caring; 5.26% playing; 0.71% secreting; 0.42% making a voice; and 0.56% agonistic.
