Abstract

Reboisation is one strategy to anticipate global warming that most easily performed. This re-plantingactivity is very urgent to be conducted in mangrove areas, since the impact of global warming are very profound atthe coastal and lowland areas. Its implementation has been done, but failures are still high. One of the causes oftenfound in the field is pests. Its efficient and effective control are still faces various obstacles. Wideng (Sesarma) isvery often perform as pest to the mangrove propagules, therefore could affect the community structure. It is thereforeimportant to establish conceptual study and research on wideng control, especially those that are able to promoteparticipation and benefit the community. One potential control is to empower its natural predators, the mud crabScylla. The purpose of this research is to analyze the level of Scylla predation, namely of total prey consumed, preysize and prey density presentation. It is also intended to determine weight gain and predation behavior byScylla. Two units of the test cage were placed in the pond in Tapak Tugurejo Semarang with Complete RandomizedDesign (3 treatments and 5 replications). Data on predation tests are descriptively and statistically analyzed usingJMP software, whereas the study of behavior was analyzed descriptively.The results demonstrated that Scylla is able to prey and consume wideng namely the life ones. Scyllaperform no respecter of prey body size, since wideng of small body size (2-3 cm), preferably the same to themoderate size (4-5cm) and large size (> 5 cm). The level of consumption gives a high weight gain for Scylla,between 182 - 197% in just 6 days. In term of presentation of the treatment, showed that wideng really liked thepresentation of the feed lot at once rather than presenting a slightly but gradually. Finally, feeding on Scylla withwideng through cultivation, particularly in fattening purposes, using wideng is reasonable and flexible to be appliedfor fishermen. This concept, together with other control components (components of a dissertation study of theauthor), is very supportive on the wideng control whiles provide economic benefits to the society atonce.

Abstract

The breakwater of Tanjung Emas Seaport is designed to absorb seawave as well as increase ships stability.Such water stability will trigger the light and small particles to deposite onto the bottom of the water body,eventhough these are easily re-suspended and initiate to create turbidity. Turbididty is one factor affecting Mollusccommunity. In facing the global climate changes, there will be a seriuos problem triggering the turbidity of theseawater and so do the organims. Researh were aimed to study the benthic Mollusc community in different turbiditylevels. Justified ramdom sampling was applied in 14 stations. Community structure of the molluscs were analizeddiscriptively as well as through Shannon-Wiener (H’) and evenness (e) indeces.Result showed that turbidity in PTES varies between 06,750 – 45,250 NTU. Such qualities were relativelyhigh range and can be tolerated by several given species, mainly Gafrarium tumidum, Nuculana acuta and Pyrenesp. These three above species could live within such high turbidity levels, since some of material are part of theirdiets without disturbing their respiration fuction. The highest diversity index H’ was 1,68 and found in Station 5,which is in accordance with its highest turbididyt level 45,250 NTU. The smalest turbidity level occured in Station 8and it was related to smaller diversity index (0,24). There was a tendency, the smaller the turbidity levels the smallerthe diversity indices. Such relatonship was consistence to the other three stations, namely 9,10 and 11. Exceptionwas found in Station 1, where different dominant species occured and diversity index was relatively high. It isbelieved these are related to the presence of warm outlet of Indonesia Power sewage reaching 32,5 centdegree.

Abstract

Traditional knowledge of medicinal plant use in many regions of Papua New Guinea and the East New Britain Province is poorly described and rapidly disappearing due to some factors like religion and outside influence that may have contributed to the fading away of indigenous knowledge within each ethnic group. The main aim of this  research was to identify some of the plants used as medicinal plants in the Vunatui clan of the Tolai society in East New Britain, PNG and determine the type of disease or conditions being treated by these plants and how the plants are being prepared. The main data of this researched was compiled through consultation and interview with three of the traditional doctors “tena dawai” within the clan who helped to provide the information on plants used as medicine. Although most of the traditional or indigenous knowledge in East New Britain are based on secrecy and must be paid for in some circumstances if one wants to learn or know about it, the medicinal doctors were willing to provide information after they were made aware of the purpose and benefit of this research. There were about 50 species of plants gathered in this research and there is variation shown among the plants. The plants range from herbaceous to vines, shrubs and trees and were found on the coastal areas to mid- mountains of the area of study. Different methods of preparartion were used but the most common method used was infusion. From the methods of applications that were used, oral administration was the most common.Key words: Traditional medicinal plants, Vunatui Clan, tena dawai,

Abstract

Water media influences the effectiveness of the use of ovitrap media for Ae. aegypti. Water media which is prefered by the mosquito as well as inhibition the premature growth have huge potency in controlling Ae. aegypti. The objective of this study were to investigate the preference of oviposition of Ae. Aegypti and to determine the premature growth of Ae. aegypti in water media containing a combination of organic matter and different chlorine concentrations, also to examine the interaction between organic matter and chlorine to the preferences of oviposition and the premature growth of Ae. Aegypti. The method of this study is done by experiment by applying Completely Randomize Design (RAL). This study used two types of water media combination. The media combinations contained organic materials and chlorine with seven different treatments. They were well water (control), water added with soil and hay-soaked water added with chlorine by 5, 10, and 15 ppm respectively. The findings show that Ae. aegypti have the tendency in choosing hay-soaked water in lay the eggs since it has abundant content of organic matter in it. The mean amount of Ae. aegypti oviposition in the water medium combination ranged from 84 to 152.7 eggs, while the percentage of premature survival rate ranged from 59.4% to 97%. In conclusion, the study showed that the preference of oviposition is highly influenced by the organic matter content of the media. Both organic matter and chlorine do not inhibit the premature growth of Ae. aegypti. However, the interaction between organic matter and chlorine to the preferences of oviposition and the premature growth of Ae. aegypti was not found. Keywords: Aedes aegypti, combination, ovitrap, organic matter, chlorine.

Abstract

Plankton is organisms that had an important role in water as natural feed of fishes and as an indicator. This study aimed to identify water quality which was suitable for fish cultivation reviewed from physics-chemicals parameters of water and its saprobic status in Tambak Lorok Tanjung Mas Kota Semarang. Sampling were take based on 5 stations that could represented from plankton variety of condition water stability . Plankton samples were by using net plankton number 25, then preserved with alcohol 70% and formalin 4%. Variables of ponds water quality measured were temperature, salinity, dissolved oxygen, pH, turbidity, N concentration, and Pb content. Identification of planktons used SRC method under microscop. The result of plankton analysis in Tambak Lorok water showed 42 phytoplankton species, the commonly species found are Coscinodiscus centralis, Coscinodiscus granii, Gyrosigma sp., Navicula radiosa, Pandorina sp., and Melosira sp. Meanwhile, zooplankton found was 22 species with common species are Cyclops, Harpaticoida, Tricodesmium evythraeum, Brachinus plicatilis, and Lensia subtilis. Phytoplankton diversity index are 0.057-0.367 and equity index are 0.025-0.176. Zooplankton diversity index are 0.247-0.360 and equity index are 0.157-0.201. This indices showed that there were low level of species diversity and community stability, dominance since the species occurred. Measurement of water quality variables indicated that Tambak Lorok had been contaminated and needed a preliminary management before d be used as fish cultivation ponds, because the analysis result was not appropriate with Government water quality  regulation. Based on the measurement, soprobic index categories on α/β-Mesosaprobic to Oligosaprobic phase and the degree of pollution is very mild to moderate. Keywords :  Community Structure, plankton, Tambak Lorok, Tanjung Mas, Semarang

Abstract

Diatom is a unicellular micro algae that had an important role in the food web and major contributor of oxygen in the water. The short life cycle, rapid reproduction, cosmopolite, wide spread distribution, variation in population, most are sensitive to the environmental changes, easily handle samples and identification, low cost of  sampling and data analysis may promote diatoms as a powerful bioindicator of water quality. The unique siliceous frustules make diatoms able to preserve in the sediment. Rawa Pening is a semi natural lake that administratively surrounded by four districts that consist of 27 villages. The main problem of this lake is erosion in the upstream and sedimentation in the downstream area as well as uncontrolled of aquatic plant growth, particularly water hyacinth (Eichornia crassipes) that induce lake shallowness. For people who live around Rawa Pening, this lake had been used for agricultural irrigation, fisheries, electricity power and tourism. To conserve the lake, as 3rd World Water Forum in Tokyo, March 2003 and 2006 – 2009 National Research Agenda there is a need of limnological research on the environmental changes. This research was conducted in order to study the potential used of epipelic diatom as bioindicator of lenthic ecosystem, particularly Rawa Pening Lake. Water and sediment samples were taken from 27 sites from inlet, outlet and water body of Rawa Pining Lake. There were 254 diatom species that consist of 8 Centrophycidae species and 246 Pennatophycidae species. The population varied between 6,989 and 3,781,000 individual/gram. Based on diversity indices of diatom, some part of Rawapening Lake was unstable, whereas the others were stable based on the diversity indices. Based on epipelic diatom, Rawa Pening Lake and its catchments area might be divided into 3 groups: agricultural lotic ecosystem, settlement lotic ecosystem and lenthic ecosystem. The high population of Synedra ulna, Nitzschia palea and Aulacoseira indicated that the lake is eutrophic that tent to be hypereutrophic. It was supported by high concentration of total nitrogen and phosphorous. The concentration of heavy metals Cadmium, Chromium, Copper and Lead were very high in sediment. However, the government of Indonesia has not yet set up sediment quality criteria. The following research would be proposed on this matter. Key words: diatom, bioindicator, water quality, Rawapening
