Mangrove vegetation growsalong the coastal line and iscapable of thriving in salty water. Therefore, the study reported in this articlesought to describe the production and decomposition rate of Ceriops tagal litter in Tanjung Panjang Nature Reserve in Randangan Sub-District, Pohuwato District, Gorontalo Province. A survey method was employed, and a purposive sampling technique was used for selecting the research site. The data of litter production was collected using a litter trap of 2m x 1m. Decomposition data was collected using a litter bag sized of 1m x 1m. The results showed that litter production containing leaves at Station I reached 46%, twigs 40%, and fruits 14%. At Station II, the production of litter containing leaves reached 42%, twigs 45%, and fruits 13%. At Station III, the production of litter containing leaves reached 48%, twigs 43%, and fruits 9%. The decomposition rate (R) of C. tagal litter at each station was obtained with an average on the 14th day of 0.42 g, 0.75 g, and 0.77 g, respectively. On the 28th day, it was 0.75 g, 1.00 g, and 0.89 g; on the 42nd day was 1.13 g, 1.27 g, and 1.22 g; and on the 56th day was 1.48 g, 1.62 g, and 1.59 g. The ratio of the decomposition rate of C. tagal litter on day 14 to day 56 increased. This condition was influenced by several environmental factors, including salinity, which ranged from 4.5-6.3‰, ambient temperature at 27-28°C, dissolved oxygen at 2.0-5.0 mg/L, and soil pH between 5.9-8.0.Keywords: Ceriops tagal, decomposition rate, litter production, Pohuwato

Rafflesia patma is an endemic plant of Pangandaran, West Java which is protected because of its rare status. The purpose of this research is to study the population structure, distribution patterns, and the effect of the physical environment of abundance R. patma in Pananjung Pangandaran Nature Reserve, West Java. The method used in this research was a survey method with a purposive sampling technique. Sampling was conducted using quadrat plots. The population pattern distribution was defined by a standardized Morisita index, and the analysis of abiotic environmental factors was determined by Principal Component Analysis (PCA) using PAST3. The results showed that there were 114 R. patma individuals scattered in several research areas in Pananjung Pangandaran Nature Reserve, they were Gua Parat (3 individuals), Cilegon (13 individuals), Pasir Putih (12 individuals), Badeto (48 individuals), and Curug Leutik (38 individuals). The distribution pattern of R. patma in Pananjung Pangandaran Nature Reserve was clustered with the Morisita index value (Id) > 1. Based on the PCA analysis, results that support the classification of the cluster analysis were obtained. Based on four abiotic environmental conditions analyzed, the most dominant character in influencing the distribution patterns and population structure of R. patma is light intensity.

Mangrove communities are part of the natural coastal ecosystems that have a vital role, such as the greatest source of organic material for the surrounding aquatic environment. A variety of ecological phenomenon often happens recently, either directly or indirectly affects the change of mangrove vegetations. Leaf is one of the plant organs that change shape according to the condition of the mangroves and the aquatic environment where the plant lives. The common changes of the leaves are the symmetry (morphometry), the size, and the shape. Mangrove leaves are also subjected to herbivory (predation), that will result in reduced leaf area of the photosynthesis and lowered the production of organic matter to the surrounding waters. This research aimed to determine the morphometric variation and herbivory rates of mangrove leaves at Segara Anakan Cilacap. Mangrove samples were Aegiceras corniculatum, Avicennia marina, Ceriops tagal, Rhizophora apiculata, and Sonneratia caseolaris. The study used survey method with stratified random sampling technique. The results showed morphometric variations of the five species were three variations, while the average herbivory rate from highest to lowest were: Avicennia marina (7.46%), Sonneratia caseolaris (6.91%), Rhizophora apiculata (4.08%), Aegiceras corniculatum (3.42%) and Ceriops tagal (3.00%). The difference of age and species of leves affected the herbivory level.

The high changes of Serayu River land use is resulting the high of load particle sedimentation into the body of water. Turbidity will accumulate in the downstream or estuaries which would have an impact on biota, especially plankton as primary productivity and secondary productivity. This research is conducted with a survey method and purposive sampling technique. Estuary Serayu River is divided into 5 stations, starts from the nearest to the sea (1) with 26 ‰ salinity and the furthest stations from the sea (5) with 8 ‰ salinity. Samples of water and plankton are taken at the time of high tide and low tide every month, for 4 months (August, September, October, and November 2016). The obtained data is analyzed by PCA to study the environmental factors towards primary productivity and secondary productivity. Based on the research result environmental factors has relation waters estuary productivity of Serayu river on the highest and lowest tide those are lightness, level TSS and pH.

Filariasis is a chronic infectious disease caused by filarial worms and transmitted by Mansonia, Anopheles, Culex, Armigeres mosquitoes. Living microfilariae are channeled and lymph nodes and cause inflammation of lymph node channels. This disease is one of the serious public health problems in Indonesia. Almost all regions of Indonesia are filariasis-endemic areas, especially in Eastern Indonesia which has a higher prevalence. The purpose of this study was to determine the factors associated with the incidence of filariasis in Pota District, East Manggarai Regency in 2016. The location of this study was carried out in Pota Subdistrict, East Manggarai Regency, with sampling in 4 villages conducted for approximately 2 months, namely in September to October 2016. This study used a descriptive survey method and finger blood survey to see the description of physical environmental factors and behavior of the head of the family in filariasis disease and type of microfilariae. Independent variables (free), which are included in this variable are environmental factors and behavior of the family head with indications of the physical environment (temperature, humidity, place of breeding of family mosquitoes and mosquito resting places) and the behavior of the head of the family which consists of knowledge and attitudes (knowledge of disease Filariasis: Dependent variable (bound) or variable Y which is expected to experience changes due to the influence of independent variables included in this variable is the incidence of Filariasis Disease. The population in this study were all family heads in Pota District, totaling 4570 populations, with Sampling technique is proportionally 154. Data is processed and analyzed descriptively presented in the form of frequency distribution tables of each independent variable with a 95% confidence level (α = 0.05). The results of this study indicate that the four factors include environment, work, Air humidity, per Night effects significantly have a risk of filariasis transmission (p> 0.05). Of the various species found two types of filariasis species namely Wuchereria Bancrofti and Brugia malayi. The conclusion from the results of this study can be concluded that the incidence of filariasis in Sambi Rampas subdistrict, East Manggarai Regency was caused by environmental factors, occupation, air humidity, human behavior and all blood survey samples found (100%) positive for filariasis Wuchereria Bancrofti and Brugia Malayi.
