Abstract

This research was conducted in the western coastal region of Buleleng which includestwo districts, namely: Seririt District and Gerokgak District. The research aims were (1) toanalyze the trend of the dynamics of sea level in the period of 2002 to 2010, and (2) to predictthe spatial distribution of flood of sea water. The data used are Envisat satellite altimetry datafrom the results of post-processing data, which were then analyzed the trend of mean sea leveland forecast of sea level rise for year 2020 using linear regression analysis. To determine thespatial distribution of area flood of sea water, then the data of level rise forecast were analyzedwith Geographic Information System (GIS). The results of this research define that the functionalrelationship of the trend of mean sea level rise in the area of research is y = 0.051 x + 1.612. Theprediction of mean sea level rise that is obtained every year 5.1 cm and for 2020, the sea levelrise is predicted to reach 2,224 cm. The width of coastal area that is potentially flooded of seawater reaches 812.954 m2 (0.227%). Spatially, the widest food area is Pejarakan village and thenarrowest is Celukan Bawang village. The percentages of the villages that are flooded to areavillages show a relatively homogeneousdistribution.

Abstract

The communities of Serangan have a habit to use turtle for trading, consumption, customs and religion. After the execution of Act of rare animal, the community became anxious, because it was prohibited using turtles for the above purposes. The community claimed the government so that it provided exemption using the turtles, but the government still wanted to preserve them. The two diversity of interests caused pro and contra of using the turtles so it aroused discourse internationally, nationally and regionally that gave an impact to the image of Bali society specifically the two villages was said as a society of turtles butcher by international world. The result of this research showed that before the execution of Act No: 7 and 8 in 1999 on the preservation of rare animal the use of turtle is a part of people of Serangan life for trading, consumption, custom and religious ritual. However since 2005 the use of turtle was changing from extractive to non extractive. Further there was also a changing in giving the meaning of turtle that is from exploitation to be the preserver through the release of tukik to the sea to maintain the balance of nature/sarwa bhuta hita. Since 2005 the use of turtle as religious ritual has been changing. Before 2005 the people used the big-size and large amount of turtles for ceremony. But since 2005 they are willing to use the small-size of turtles (boko), even if they did not get any single turtles, they replace it by using a duck. The changing of Serangan people perception regarding turtle that is from turtle consuming to turtle preserving can be found in awig-awig (adat law). Of adat village the turtle preservation was established, releasing tukik to the sea both as tourist attraction and as the form of turtle preservation that is taken from the conservation.

Abstract

The main purpose of the research is to analyze the needs of urban forest in the Kupang City based on the sink of CO2 anthropogenic. Primary data collected through field surveys and laboratory analysis of leaf samples using carbohydrate method. Case studies and literature are used to obtain secondary data from relevant agencies or literature, especially the results of studies with similar cases. The results showed that increasing emmission of CO2 anthropogenic. Total emissions of CO2 anthropogenic come from the use of fuel oil and gas and electricity consumption was 393,498.003 tons/year, in 2015 increased to 490,673.45 tons/year, and in 2025 reached 710,928.38 tons/year. Urban forest area in the city today in many forms of 969.35 ha or 5.38%, but from the region of the pure function as urban forest is only 177 ha or 0.98%. Based on the absorption of CO2, the needs of urban forest area in the city at this time are sufficient, but based on Government Regulation number 63/2002 that establishes urban forest land area of at least 10% of the area of ??the city, the area available has not yet qualified. CO2 absorption of 9 tree species studied vary between tree species, depending on the mass of net carbohydrates, leaf area, and number of leaves per tree. Plants that have high the absorptive capacity of CO2 are the jackfruit and the banyan tree with value of 453.95 and 428.48 kg/tree/year, respectively, while the lowest  is flamboyant with 0.12 kg/tree/year of CO2 absorption.

Abstract

Denpasar city which is the center of the development requires a quite a lot of water. Intensively the taking of groundwater can lead to changes in soil structure or water cycle and environmental damage. The aims of this study are to examine aquifer as a water carrier layer that that spread laterally and vertically. Aquifer analysis performed by analysis of aquifer parameters from well bore data. West Denpasar District is a centralized location of underground water flow to the sea, because of this the region has a high potential for groundwater discharge which values >10 liters/second. Generally, augmentation of ground water from rainfall that is equal to 1.528 liters/second. Data from well bore indicate good water carrier layers (tuffs, sand, gravel) are at more than 20 m depths, there is free ground water from a depth of 12 m but with a small discharge. After 20 m depth, there is a new semi-free aquifer until more than 24 m depths. Well bore in the Mahendradata Street showed groundwater discharge is moderate with value 8.467 liters/second. In this well bore two types Aquifer types was found there are unconfined aquifer and Semi-confined aquifer. Unconfined aquifer located on the surface of the rock layers. Therefore, Semi-confined aquifer is more dominant because the layers are rare waterproof that located in Palasari formation layer. The aquifer layer was also found in the relative position of more than 30 m from the local surface.

Abstract

Research  on “Birds as an Ecotour Attraction in Ubud Tourist Resort, Bali” (Burung sebagaiAtraksi Ekowisata di Kawasan Pariwisata Ubud, Bali) was undertaken in 2013. Aims ofthese research were as follows: first, to find out birds observed in Ubud Tourist Resort, Baliand second, to find out their potentials as ecotour attractions.Samples were collected by exploring the study sites and running interview between July andOctober, 2013.  Observation was carried out by using binoculars and number of individualsof birds was counted by using a counter when necessary.  Birds were identified such asthrough direct observation on the species, or through their calling.  Results of observationwere compared with hand boooks, such as Mackinnon (1990) and Mackinnon et al. (1992).Birds data were recorded either on their species and on numbers (relative)/freqency, and theresult was typed in tables.  The data provided such as the status (protected/not), migrantspecies or not, as well as their distribution.  In addition, locations where birds have beenused as a tour attraction (ecotour attraction - bird watching), and how to set up theirproducts were reported.From this research it can be concluded as follows.  In Ubud tourist resort at least 67 birdspecies have been identified, in which 7 (seven) were birds that were restricted theirdistribution in Indonesia, namely:  Halcyon cyanoventris, Alcedo caerulescens, Paddaoryzivora, Prinia familiaris, Treron griseicauda, Dicaeum trochileum, and Gallus varius.In addition, from this reserach it was observed seven species of migrating birds: Hirundorustica, Merops philippinus or M. superciliosus, Accipiter soloensis, Actitis hypoleucos,Tringa glareola, Gallinago stenura, and Apus pacificus.From all birds observed, there were 14 species that were classified as protected species inIndonesia, namely: Sturnus melanopterus, Anhinga melanogaster, Bubulcus ibis, Egrettaalba, Egretta garzatta, Egretta intermedia, Halcyon cyanoventris, Halcyon chloris, Alcedocaerulescens, Haliastur indus, Nectarinia jugularis, Anthreptes malacensis, Rhidipurajavanica, and Accipiter soloensis.Based on data from survey and interview, it was revealed that seven trekking routes wereidentified in which birds were utilised as ecotour attractions or the routes of which have apotential to be developed as ecotour attractions (where birds utilised as their touristattractions in Ubud tourist resort and ajacent areas), such as: (1) Subak Sok Wayah Ubudand its surrounding areas; (2) Melinggih - Subak Kembang Kuning and their surroundingareas; (3) Laplapan, Banjar Sala and their surrounding areas; (4) Kliki (Bangkiang Sidem)and its surrounding areas; (5) Tirta Temple Mas Village and its surrounding areas; (6)Banjar Pande Peliatan Village - Alas Arum temple and their surrounding areas; (7) Petuluand its surrounding areas.Community perceptions on bird conservation and bird based ecotoursim in Ubud touristresort showed that: in general the community believed the need for conservation of birds,and they said that the development of bird based ecotour activities have given benefit for thecommunity, such as providing jobs and source of income for them, even though some constraintsstill need to be overcome, such as trekking trails that have not been perfect, the smell of fecesof birds, and weekness in human resources capability.From statements of stakeholders (community, govenment, industry, and visitors), it can berevealed that the commitment of all is needed in bird conservation, because they becomeimportant part of nature, in the sustainability of nature or ecosystem. The media for meetingand discussing for development of birds based tourism activities especially bird watching inUbud tourist resort need to be improved.Limitation in time may caused incompleteness of the bird data collected on this research. Asa result, a longer time in research is recommended. In addition, other studies or research arealso needed to get more data, the data of whcih their availability are still very limited.  Forexample, research on bird habitats are also need to be undertaken.

Abstract

Malaria is an endemic disease in Timor Tengah Selatan. The data of Annual Parasite Incidence (API) 2014 showed that there were 8.2/1000 population who were infected by this disease. It is still above the national rate of 5/1000 of the population. Cases of malaria spread in almost all areas of health centers with different topographic characteristics that allow the Anopheles larvae breeding sites with different characteristics. The study was conducted to determine the factors of physical environment and biological environment that influence the existence of Anopheles larvae in breeding sites based on topographic characteristics of Timor Tengah Selatan. This study applied across-sectional study approach. The research activities were started by sampling health centers and villages locations. The locations were determined representation of the three characteristics of the topography region, namely lowland (coastal region), plains (the hills) and highland (mountain region). Of 18 variables observed, there are two variables that significantly have relationship with the existence of the Anopheles larvae in breeding sites, namely (1) water depth brood with an average depth 0,5682 m, p value of 0.000 and (2) water clarity brood with p value 0.045 at 95% CI 1.172 to 30.725. Some variables show that: the average of air temperature is 31.82 °C, the average of water temperature is 25.73 °C, the average of PH water is 8.1, the average of air humidity is 72.55. A total of 63.6% breeding sites is directly exposed to sun, 81.8% of breeding sites is stagnant water, the average of area of breeding sites is 4.0682 m2, a total of 63.3% of breeding sites there is water all the year, a total of 50% of breeding sites is clear water, a total of 100% location found public activities there and at all locations, there are no mangrove sand algae. Based on topography region, the most breeding sites of Anopheles larvae found in the coastal region (lowland). It is recommended to list and eliminate all potential breeding sites of Anopheles larvae. District Health Office should control the activity plan and intervention schedule of health centers to eliminate Anopheles larvae breeding sites. During dry season, the society should control to dry the puddles too.

Abstract

Fluctuation of water regimes where plant grows has been known to affect the plant chemical, nutrition compositions and plant chemical defenses, which can affect the vulnerability of plants to insect herbivores. This research aimed to compare the concentration of plant nutrition and chemical defenses of Melaleuca ercifolia grows on different water regimes, subsequently to insect herbivore attacks. The leaf total nitrogen was higher in plants growing in water fluctuated areas, therefore the insect herbivores compared to plants growing in prolong-flooded condition. Insect herbivores prefer to consume plants that are more nutritious and less affected by the plant growing conditions.

Abstract

The diversity of marine biota resources is very high, therefore it is necessary to be recovered for our life need. The objective of this research is to know the antifungal ability of marine biota derived from Bali Island against Fusarium oxysporum f. sp. vanillae. Samples were collected at the intertidal zone of seven beaches around Bali. Extraction of antifungal substance of raw material extract was conducted using various organic solvents until the best ability was obtained. The dry material extract was then screened using well diffusion method. The method was also used to determine the inhibition indicators to Fusarium. The methanolic extract of Aglaophenia sp. marine animal was able to suppress the Fusarium effectively, with minimum inhibition concentration (MIC) of 0.05%. The extract inhibited the colony growth, total of conidial forming, total of growing colony, total of mycelial dry weight, total of mycelial protein, however, increased fusaric acid production of the pathogen.
