Ngurah Rai Forest Park Bali is a mangrove conservation which covers 1,373.50 ha; the largest mangrove forest area in Bali. However, its strategic location, in the center of business and the golden triangle of tourism (Sanur, Nusa Dua, and Kuta), creates pressures from various interests. This threat causes 253.40 ha of mangrove forest area in Ngurah Rai Forest Park Bali severely damaged. The aims of this study were: (1) to analyze the forms of land function change occurred in Ngurah Rai Forest Park Bali; (2) to analyze perception of the community around Ngurah Rai Forest Park Bali about mangrove conservation; (3) to analyze the behavior of the community around Ngurah Rai Forest Park Bali about mangrove conservation. The research was conducted from May until July 2018 in Tuban and Pedungan District. This study uses 2 (two) analytical methods, 1) literature study methods, to determine the form of land function change that occurred in the Ngurah Rai Area of ??Bali, 2) categorical quantitative analysis method to determine the perceptions and behavior of the local community. The categorical quantitative analysis method was used to categorize the perceptions and behaviors of local people. It is qualified into 4 (four) categories on a Likert scale. The results of the questionnaire collected were categorized into 4 (four) levels and discussed descriptively. This paper was based on primary data taken using questionnaire with a predetermined analysis unit to interview the community in the study area. The result presented with quantitative and descriptive analysis. The result shows that within twelve years, from 2000 to 2012, Ngurah Rai Forest Park Bali has a land function change of 29.76 ha or 2.16%; from 1,161.76 ha in 2000 to 1,132.00 ha in 2012. The level of community perception towards the mangrove preservation of Ngurah Rai Forest Park Bali is very good but the level of its community behavior is bad. It can concluded that good perception do not always have a good impact of people behavior towards the mangrove conservation.

Artificial reefs are made to act as temporary substitutes for small areas of damaged original reef. The structures attract fish and other marine organisms, which can eventually be exploited (e.g. for human food), so it is expected that they will form the basis around which natural reefs can grow and recover. The purpose of this study is to document recruitment of organisms onto the artificial structures, evaluate the effectiveness of the structures in terms of shape and recruitment potential, and use the recruitment information to show which species occur in the surrounding reefs. This research was conducted from May-July 2010 in north Bali, in the Village District Gerokgak Patas, Kampung Baru Village in Buleleng District, and Penuktukan Village, Kecematan Tejakula. The research method used was a visual census method to determine the number of fish species and fish abundance on artificial reefs at three different locations. Three replications were performed at each location. 2481 individuals from 18 families (38 species) of reef fish were observed. The area with the greatest abundance of fish and the highest number of fish species was in Kampung Baru, with 1170 individuals from 21 species of fish. Dominant reef fish species were Plotosus lineatus (Cat Fish) - 510 individuals, Pomacentrus auriventris (Goldbelly damsel)- 256 individuals, Dascyllus trimaculatus (Three spot damsel) - 335 individuals, Pseudanthias squamipinnis (Lyretail Anthias) - 320 individuals. A Sorensen analysis showed that reef fish communities on the artificial reefs in the form of 'hexadomes' were not derived from the surrounding reefs.

The Effect of Ethyl Methane Sulphonate (EMS) on Growth and Variations of Marigold (Tagetes sp.) The aims of this research are to determine the variation of marigold (Tagetes sp) derived from seed treated with EMS and to recommend the EMS concentrations that are able to induce varietion. Seeds of marigold cv Narai Orange were soaked in water for 6 hours, followed by soaking in EMS at concentration of 0%, 0.3%, 0.6% and 0.9% for 4 hours. This study employed Randomized Complete Blok Design with 10 replicates and each replicate consisted of 10 plants. Six plants were randomly chosen for measurements. The total number of samples observed were 240 plants. Observations were made on the percentage of the growth, plant height, number of leaves, number of branches, diameter and weight of flowers. Data obtained from the observations were analyzed using Analysis of Variance (ANOVA), followed by DMRT (Duncan’s Multiple Range Test) if there is a significant difference between treatments. The EMS treatment reduced all characters observed. The EMS concentration of 0.6% showed plant that had yellow flowers. The 0.9% EMS treatment resulted in one plant with chimera, 6 dwarf plants, 2 plants with thin stems, and 1 short plant with many branches. Untreated plants did not show any variation.
