Study on some reproductive aspects of blue swimming crab (Portunus pelagicus) in Mayangan waters, Subang, West Java had been conducted for eleven months (Ferbuary-Desember 2003). The blue swimming crab samples (n=556 individuals, consisted of 251 male and 305 female) were caught by fisherman using crab net and trap sized 25x70 cm. This study covered sex ratio, gonad maturity stage (GMS), gonad somatic index (GSI), fecundity and eggs diameter. During the study (carapace width varied from 63,40-159,70 mm for male and 59,30-163 mm for female), sex ratio (male : female) of the crab was 1 : 1,2. Gonad maturity stage of the crab varied from immature to spent condition. Number of the male mature gonad was found higher during February - April, while female one was in February and June. Carapace width of first mature gonad analyzed using by Speraman-Karber method were 101,5 mm (male) and 122,2 mm (female). Gonad somatic index of male and female ranged 0,57-5,59% and 0,35-5,63%, respectively. The highest value of the gonad somatic index was found in June indicating a peak of spawning season of the crab. Fecundity of the crab ranged from 64.380-1.526.600, while egg carried in the abdomen (of ovigerous female) ranged 80.998-1.343.850. The egg diameter varied from 0,09-0,48 mm, with one mode indicating a total spawner.

Plankton community has an important role in the food chain, nutrient cycle and initial succession process in the wet dune slacks. Wet dune slacks are damp or wet hollows left between dunes where have a seasonally fluctuating water table. This unique habitat has been protected in European, but in Indonesia has not been studied by researchers. The aim of this research is to study plankton distribution and abundance in wet dune slacks with physico-chemical factors that most influence. Sample was picked on February 2018 in Gumuk Pasir Parangtritis, Bantul, Daerah Istimewa Yogyakarta. There was 10 liters sample taken using bucket with 3 replications in 5 different wet dune slacks. Water sample was filtered using plankton-net 120 mesh size and physico-chemical parameters was measured. The results of plankton samples show there were 37 species of pennate diatoms, 1 species of centric diatoms, 23 species of algae unisel, 28 species of algae colony, 18 species of algae filaments, 3 species of dinoflagellates, 6 species of chlorophyll protozoa, 22 species of rotifers, 6 species of cladocera, 11 species of ostracoda, 5 species of copepods, and 5 species of protozoa. Plankton species that have succeeded in wet dune slacks are species that have a strategy of surviving in the extreme habitat by changing to resting stages, cysts, spores, and resting eggs. Phytoplankton species that dominated in the wet dune slacks was Cyclotella meneghiniana while for zooplankton was Chlamydotheca flexilis and Alona rectangula. Phytoplankton distribution and abundance was regulated by wind speed, C-organic content, alkalinity, light intensity, phosphate content, pH and dissolved oxygen. The physico-chemical factors that most influence the distribution and abundance of zooplankton was concentration of dissolved oxygen, dissolved CO2, pH, water temperature, air temperature, depth, water transparency, wind speed, light intensity, C-organic content, sulfate and phosphate content.

This study aimed to determine the parameters of aquatic environments based on physical-chemical factors, zooplankton diversity, and zooplankton abundance relationships on togok catch results. The sampling is done 3 times with 1 week interval. Based on the value of DO note that station 1 is categorized as moderate polluted, while stations 2 and 3 are still in the low polluted category. During the study there were 8 types of zooplankton consisting of Brachionusdimidiatus, Brachionus quadratus, Calanus gracilis, Calanus minor, Euterpina acutifrons, Oikopleura laboradoriensis, Oithona attenuate, and Nauplius. An index value of zooplankton averages of 1.12-1.44 indicates that moderate diversity with moderate distribution of individuals and levels of contaminated pollution is moderate. The zooplankton dominance index value shows that there is no dominant type with value 0,29-0,34. Pearson correlation results show there is no relationship between zooplankton abundance of togok catches, with a value of 0.882.

Angso Duo Market is the largest traditional market in the city of Jambi, with an area of â€‹â€‹Â± 5 Ha. The amount of waste produced by Angso Duo market every day is around 105 tons per day with a ratio of 70% biodegradable waste, 25% recycled (organic and paper) and 5% other waste. Of the 75% of waste that is around 60% is waste in the form of vegetables, most of which are mustard and cabbage. Vegetable waste has great potential to be used as organic fertilizer because it has good and complex nutrients such as protein, fat carbohydrates, calcium, phosphorus, iron, vitamins A, B and C, folic acid, fiber, water and sodium. The advantage of liquid organic fertilizer is that it contains enough nitrogen as a constituent of plant protein and chlorophyll. The results showed 6 types of bacteria namely Planococus, Neisseria, Halobacter, Azomonas, Azotobacter and Bruccella which were formulated into liquid fertilizers with a basic substrate of vegetable cabbage and mustard waste.Then tested the ability of bacteria to dissolve nitrogen, phosphorus and potassium as potential bacteria as liquid fertilizer

The work presented here was aimed at investigating the proper time (after spreading) for viability assessment and the effect of various sucrose concentrations on pollen germination in Swainsona formosa. The rate of pollen tube formation was determined for freshly shed pollen grains of glasshouse-grown plants at 10, 15, 20, 25, 30, 60 and 120-minute intervals after being plated on Brewbaker and Kwack (BK) medium. The results indicated that within 60 minutes pollen germination reached 63.70%, after which remained steady at 120 minutes (63.71%). Under the effect of various concentrations of sucrose, i.e. 0.5, 10, 15, and 20% (w/v), the germination rate of pollen grains was assessed at 60 minutes following germination. The results showed that sucrose concentration of 10 â€“ 15% (w/v) produced better germination rate (64.14%) compare to lower concentrations (19.64 and 43.58% at zero and 5% sucrose, respectively). Sucrose concentration above 15% was also found to inhibit pollen germination (48.92% at sucrose concentration of 20%).

Antipredation is one type of adaptation done by prey animals in the face of predators, both avoid and fight. The antipredation strategy most often done by some animals is to trick predators, one of them by camouflage. In the camouflaged ghost crabs performed using background matching techniques, which alter their body colors and match them to the color of their environment by adjusting the concentration and dispersal of pigment in the chromatophore (Davies, 2013). In addition to camouflage, ghost crabs also make the hole as a hiding place from predators. With reference to camouflage and antipredation strategies on Ghost Crabs (Ocypode), It is necessary to conduct a study that examines the behavior of antipredation strategies that include camouflage and architecture of ghost crab burrows in Congot Beach, Kulonprogo, Yogyakarta. The method used in this research includes taking visible light portrait data using Ocypode and its environment to analyze the RGB value, then compare the RGB composition to the specimen and its environment with the Euclidean Distance index. In addition, data collection of burrow architecture using powder gypsum was sterilized with water and then allowed to dry and then the result of the mold is measured and analyzed. The results obtained, among others, the value of Euclidian Distance of 0.12 which indicates that the color on the carapaks are in accordance with the color of the environment. Furthermore, there were 29 cast of burrow architecture consisting of 20 I-shapes, 2 J-shapes, 2 L-shapes, 1 spiral 3 Y-shape, and 1 complex form.
