Abstract

Mangroves play an important role in the coastal ecosystem of Mauritius. Two species of mangroves, Bruguiera gymnorrhiza (L.) Lam., and Rhizophora mucronata Lam., have been identified so far. The latter species is more dominant and occurs in pure stands in most of the swamps. Loss of biodiversity due to the destruction of wetlands, mangroves and corals is one of the priority issues identified in the National Environment Strategies. Mangrove and Coral reef management and protection is one of the key strategies in addressing coastal zone challenges in Mauritius. Very few scientific studies exist on mangroves in Mauritius. Currently there are no scientific studies on the fauna and flora inhabiting mangrove ecosystems. This is an area that requires further research. Therefore a lot of work remains to be done with regards to the mangroves. Moreover, future management programs will need to look into the factors threatening mangrove ecosystems.

Abstract

Development is a changing process to improve human standard of life that strongly related to the activities of natural resource utilization. It is frequently found that these activities  change the ecosystems and their resources.  Eventually, these changes will give serious impacts to the environments. The most distinct environmental problems are caused by resident migration to the coastal areas, coastal developments, and land limitation. Coastal reclamation is an example of human effort to respond to the land limitation in the coastal areas as observed in coastal areas of Labakkang Subdistrict. Reclamation activity is doing along the coast of Pundata Baji Village, whereas, in other villages, cutting off of mangrove areas as an alternative land expansion is increasingly practiced by the local communities. This Research was aimed to observe the landscape change from 1980 to 2010 at coast area in Labakkang Subdistrict. Each review considers Landsat Image Map (acquired in 1980); Landsat Image Map (acquired in 1990); Landsat  Image Map-7 Enhanced Thematic Mapper Plus (ETM+) (acquired in 2000); Spot Image 4 (acquired in 2005); and Spot 4 LAPAN (acquired in 2010). Result of research indicates that at coast area of Labakkang Subdistrict in 1980, there are 248.3 ha of mangrove vegetation, 2,756.63 ha inundation, and 4,157.0 ha open land. In 1990, there are 234.2 ha mangrove vegetation, 2,251.63 ha embankment, 933.2 ha rice field, and 582.0 ha open land. In 2000, there are 218.3 ha mangrove vegetation, 2,848.1 ha embankment, and 3,579.2 ha rice field. In 2005, it has 121.4 ha mangrove vegetation, 3,762.6 ha embankment, and 2,306.2 ha rice field. In 2010, it is found 48.9 ha mangrove vegetation, 5,029.35 ha embankment, and 749.98 ha rice field.

Abstract

Its is well known that estuaries , mangroves, seagrasses beds, and coral reefs are productive ecosystems in the coastal marine areas. The production may goes up to 3.000 g C/m2/year. It is very high compared with the production in open seas that only 50 – 100 g C/m2/year. The coastal water ecosystems are also known as good habitat for spawning, nursering, and feeding several species of fish. Therefore, the secondary productivity is also high in these ecosystems. Anthropogenic activities in order to used the resources in coastal areas, however, are often dangerous to the life of those ecosystems. Considering to the anthropogenic activities, the Indonesian government have established several law and regulation for marine environmental protection. These included the establishment of 23 marine conserves areas which cover areas of about 2.800.000 Ha. These areas are expected will be expected will be expanded to 10.000.000 Ha by the end of 1995, and 30.000.000 Ha by the year of 2000.

Abstract

Macrofouling is one of the major problems on a marine net cage culture. The attachment of macrofouling could cover the net cage and thus reduce the water circulation in the cage. Application of copper oxide paints may be able to solve that problem.  A field experiment with Completely Randomizes Design was applied with 9 treatments: paint without biocide; paints contained: 5% Copper Oxide; 10% Copper Oxide; 1% Chlorothalonil; 1% Chlorothaloni + 5% Copper Oxide; 1% Chlorothaloni + 10% Copper Oxide; 1% Zinc Omadine; 1% Zinc Omadine + 5% Copper Oxide; 1% Zinc Omadine + 10% Copper Oxide, each treatment was replicated 3 times. The research was done on July – September 2007 at Hanura Bay Lampung. Data of the abundance and diversity of macrofouling were collected weekly. The results showed that the application of copper oxide paints affected the macrofouling attachment significantly (P < 0, 01). The best result was antifouling paints contained Copper Oxide, and combination between Copper Oxide with Chlorothalonil and Zink Omadine.  However, from the economical point of view, paint with 5% Copper Oxide could be suggested for preventing macrofouling attachment on the marine net cage.

Abstract

Five sets of sediment traps were installed for thirty days (Oct.- Nov. 1999) in Banjir Kanal Timur Semarang coastal waters to examine the potency of sedimentation rate. Two sediment traps were lost in the second week of measurement. Based on the average data of three sets of sediment traps, the potency of sedimentation rate in Banjir Kanal Timur Semarang coastal waters was 6.10 cm/month. The result did not reflect the fact of the field condition. Based on the correction made  on the input of suspended discharge into Banjir Kanal Timur Semarang coastal waters and the average area of sediment distribution, the potency of sediment rate in Banjir Kanal Timur Semarang coastal water during transition of dry season to rainy season was 0.35 cm/month.

Abstract

In order to determine the extent of eutrophication due to pollution of organic matter from brackishwater shrimp ponds, on the north coast of Central Java, chlorophyll a and nutrient concentration were measured in near shore waters. It was revealed that chlorophyll a content in the study area were considerably high, ranging between 83 and 332 µg/l. The evidence of eutrophication was also supported by the relatively high level of nutrient, in which nitrate levels ranged between 1.295 and 2.060 mg/l and phosphate ranged between 0.093 and 0.270 mg/l. The relationship of chlorophyll a and nitrate indicated negative of chlorophyll a and phosphate also indicated negative correlation with regression : P = - 0.2587 Chl a + 0.1945. This suggests that the increase in chlorophyll a is accompanied by a reduction of both nitrate and phosphate, which may be caused by luxurious consumption of nutrient by phytoplankton in the surface water.

Abstract

The establishment of the plywood factory in “Sumbersari” has changed the pattern of land use. As in many other north coast villages along the Java Sea, agricultural land can be divided into two major categories, namely tambak (brackishwater ponds used for aquaculture) and sawah (irrigated land used for wet-rice cultivation). Landholders may thus own tambak and/or sawah. Tambak can be further divided into tambak bandeng (milkfish brackishwater pond) and tambak udang bago (giant-tiger shrimp brackishwater pond). Both can be farmed alone or they can be combined, which is locally called tambak campuran (mixed brackishwater pond). Tambak bandeng are sometimes further differentiated from tambak ipukan (fry pond), a smaller type of tambak designed for nursing milkfish fry to fingerlings. Still another type of tambak, which is only a portion of an irrigation stream or canal where landless peasants trap fish and shrimp with a bamboo fence, locally called tambak kali (canal pond).

Abstract

A wave runrup height on a coastal structure with sloping face is one ofthe considerations in the planning and design of sea—walLs or brealcwaters. In this paper, a wave run—up height on rock slopes of a coastal structure is presented using the empirical approach based on incident waves entering coastal structure. A height and increasing level of wave run-up hom incident wave amplitude are presented on rock slopes of a coastal structure with various angle of structure slopes and various water depths. The influence of incident wave height and wave period on the wave run-up height are described through the correlation analysis, and the probability distribution of wave run-up height is described as a Weibull distribution.

Abstract

The Coral Reef Rehabilitation and Management Program (COREMAP) is a 15-year program of theGovernment of Indonesia. It has been working at several sites in Indonesia since 1998 to achievesustainable use of coral reefs through the delegation of management authority to local communities.The establishment of effective models for participatory and community-based management is the core ofthis program. The model for community-based management includes community participation,community capacity building, promotion of alternative income generation, establishment of coral reefmanagement plans, community marine sanctuaries and community reef watcher programs. This paperdescribes the experiences and lessons learned in Phase I of the COREMAP Project in implementingcommunity-based reef management at Senayang and Lingga Islands, Riau Province. It is argued thatthe involvement of the community in the planning and implementation process of coral reef managementwill improve the management and conservation of coral reef ecosystems. It is hoped that the Indonesianexperience will contribute to the comparative literature on coral reef management.

Abstract

Since late 1997 Indonesia has been overwhelmed by monetary crisis and low income communities including fishermen received the worst impact of it.  This study was intended to see whether there was a difference in food consumption and the nutritional status of the underfive years old children in the fishermen community before and during the crisis. Sixty three subjects were chosen by cluster random sampling method and were followed from June 1998 to August 1999.  Food consumption data were gathered by weighing method for two days and food frequency questionnaires.  Paired t-test was used in the analysis. The study revealed that the families income almost doubled, the food consumption was significantly increased in term of energy and protein.  It was found that children have more frequent meal per day and more varieties of food eaten daily.  The children’s weight and height increased in an average of 2.5 kg and 8.7 cm, respectively.  The nutritional status in aggregate data showed an increase in height per age but slightly decrease in weight per age and weight per height indices but not statistically significant.  By group analysis, more children had lower nutritional status in all indices. It is concluded that there were improvement in food consumption of the underfive years old children, as the children grow older.  However, their nutritional status became lower. The primary health care providers in the area should be informed on this situation.  It is important that they should direct nutritional education program to improve the nutritional status of the children in its working area.
