The problem of domestic waste in Soragan has not completely been solved by Bantul municipal government. The government has realized this problem, however, it has not found an appropriate long term solution. The objectives of the research on community-based waste management are (1) to describe a community-based domestic waste management in Soragan Bantul municipality, (2) to identify the problems in the community-based domestic waste management, and (3) to recommend the solutions for improving the community-based domestic waste management. The research was conducted in Soragan in which a pilot project of the community-based domestic waste management has been initiated. The descriptive qualitative research was employed in this research. Data were collected with interview, questionnaire, observation, and documentation. The collected data were validated and analyzed qualitatively. The findings of the research are as follows :. Firstly, the pilot project of the community-based domestic waste management in Soragan, Bantul municipality has successfully been carried out by using 3R (reduce, reuse, recycle) principle and has reduced the amount of waste in Temporary Waste Dumping (TPS) up to 73%. Secondly, the community-based domestic waste management using 3R principle is a paradigmatic solution. Thirdly, the main problem of carrying out the community-based domestic waste management is how to change old paradigm of “throwing out the waste” to “managing the waste”. The other identified problems are : (1) the municipal government has not appreciated the people who have been sorting domestic waste; (2) there is no mechanism and person to supervises and evaluates the management; (3) the management has not been provided with supporting facilities and infrastructures; (4) sorting domestic waste has not really been completed; (5) people do not form new cadres who have capability and integrity to manage waste. There are six recommendations to manage domestic waste. Firstly, the government, RT boards, and managers plan to facilitate people measurably how to sort domestic waste properly. Secondly, the government organizes and gives incentive and disincentive to encourage people. Thirdly, the government, RT boards, and managers make a mechanism and appoint persons to supervise and evaluate the management. Fourthly, the government provides facilities and infrastructures to support the management. Fifthly, managers and RT boards find strategies to form new cadres who have capability and integrity to manage waste. Sixthly, the community-based domestic waste management is a suitable model developed in urban areas.

This research is a study on the waters quality observed through the content of carbonate and organic substance found in the bed sediment of Serang river estuary in Kulonprogo. The result of the research is aimed to provide the data about the content of carbonate and organic substance as well as the size of granule. Then, in turn, this result will help to monitor one of the waters quality parameters in that area, besides it will provide the consideration in running the business on fishpond cultivation. Research method applied in this research is a descriptive method and the data is administered explosively, whereas the sampling is done using the purposive sampling method. The analysis on carbonate and organic substance is conducted chemically on the bed sediment of the waters, and the granule analysis is done using sieve shaker whereas the analysis of sediment distribution in the location is done using 4 statistic parameters : mean, deviation standard, skweness and kurtosis. The result of the physical analysis indicates that bed sediment of Serang river in Kulonprogo consists of granular silt, silted very fine and sand. The highest content of carbonate is found for about 16% - 16,4% in coastal area, the estuary consists of 9,2% - 9,6% and the river consists of 9,1% - 9,8%. The highest content of organic substance is found in the estuary and the lowest is found in the coastal area, whereas the content of it in the river is between them. Rubbish and organic waste accumulated in the estuary influence the level of the organic substance content, however, as a whole the content of organic substance in the estuary is in the medium classification.

Purworejo Regency is one of the five areas affected by the Java tsunami run-up on July 17, 2006. Based on the results of the Rapid Survey by BPDP and BPPT, along Pantai Kebempuan is the location of the tsunami run-up in Purworejo Regency at coordinates 109,912 LS -7.85 East BT 1.7 meters. The purpose of this study is to estimate the tsunami travel time, distribution of tsunami wave heights and tsunami coverage areas due to the impact of the Java earthquake on July 17, 2006 at Pantai Kebempuan, Purworejo. The method used is a descriptive analytical method with a quantitative approach. The data used in this study are the high point, bathymetry, earthquake parameters, tidal forecasts for the waters of the Kebempuan coast, Geo Eye 1 image data, and beach slope. Tsunami modeling using COMCOT v 1.7 software with the Java 17 July 2006. Based on data processing, it is known that the maximum wave speed is 3.8788 m / s. In the 40th minute, the initial amplitude of the tsunami wave of 1,644 meters had reached the Kebshore Beach. The widest tsunami coverage area and the maximum farthest distance to occur on the Labor Beach are 1.23 km2 and 1.4 km. Based on the results of verification with an RSR value of 0.26. The results of validation of tsunami simulations using COMCOT v.17 note that the height of the model tsunami run-up is quite in accordance with the run-up data that occurred at the time of the incident, with an RSR value of 0.29 and a CF of 1.63.

Ship maintenance is necessary and must be implemented. Among maintenance is corrosion prevention. The corrosion of a ship cannot be eliminated, but can only be reduced to a level of malignancy. There are two types of corrosion prevention, namely passive and active prevention. Passive prevention that is commonly done is by painting, while active prevention is by installing Zinc Anode Protection (ZAP). The need for ZAP on the ship depends on the wet surface area of the ship, the replacement period, the type of material from the ZAP, and the size of the ZAP. Installation of ZAP on a ship is generally done by bolting it on the ship's body. The distance between one plate and another is not the same. Placement of ZAP is installed in relatively large flow sections around the keel and those located in the eddy area around the propellerinstalled tighter than other areas.
