Abstract

The distribution, graduation and conservation of Megapodius reinwardt based on the ecological knowledge of local residents to support ecotourism on moyo island, has been carried out. The objectives are: 1) to obtain an accurate picture of the distribution of the population and its behavior, 2) knowledge of the ecology of the local population, 3) perception and behavior of the local population, 4) to increase the population, and 5) to carry out conservation to prevent its extinction in the Moyo Island. This research consists of two stages of activities, namely first, mapping population distribution, nest analysis, diseases, pathogens, interviews and discussions with local community about their perception and knowledge about M. reinwardt, document study about tourist visits; second, building awareness and participation of local community to support M. reinwardt conservation activities, formulating its conservation design and identifying potential nests as tourist attractions. The perception of the local residents of Moyo Island towards the existence of M. reinwardt is useful in supporting the fulfillment of their life needs directly or indirectly. Locals believe that by keeping M. reinwardt, his life needs can be met. In addition, the locals of Moyo Island think that laboring the bird at the time of laying eggs will be "Mali" or bring bad luck to hunters. The attitude of the local residents of Moyo Island towards the preservation of M. reinwardt is mostly 85% of residents agree with the preservation of M. reinwardt on Moyo Island, 10% are still hesitant and 5% disagree. The efforts to manage M. reinwardt as one of the tourist attractions, must involve and be able to accommodate the needs of local residents, tourists, tourism entrepreneurs and the government. For the success of the bird conservation efforts, six things must be considered, namely: 1) an agreement on the recognition of the minimum rights of group members; 2) the clarity of the boundaries of the scope of control of each active management community group; 3) the suitability between the cost of nest management and the benefits obtained; 4) conflict resolution mechanisms; 5) firmness in the application of sanctions and 6) willingness to receive knowledge/information and technology on the conservation and management of M. reinwardt from outside the moyo island area.

Abstract

Orange-footed scrubfowl (Megapodius reidwardt) are protected species and need to be preserved. Orange-footed scrubfowl (Megapodius reidwardt) are terrestrial birds that build nests on the ground. To maintain its sustainability, it is necessary to have knowledge about the characteristics of orange-footed scrubfowl nests. Kerandangan Natural Tourism Park is one of the places where orange-footed scrubfowl are found, but until now there is still no information about the characteristics of orange-footed scrubfowl nests. So this study aims to analyze the characteristics of orange-footed scrubfowl nests in Kerandangan Natural Tourism Park. The method used in this research is descriptive exploration, the research variables include physical parameters of the nest, environmental parameters of the nest, chemical parameters of the nest mound and plant vegetation around the nest. The results showed that the diameter of the nest ranged from 400-590 cm with a nest height of 85-154 cm, the number of laying holes ranged from 1-3 holes and the soil texture class of the nest mound consisted of sandy loam and loam. Environmental parameters obtained average temperature outside the nest 27,9oC, average temperature inside the nest 28,6oC, average humidity outside the nest 80,3%, humidity inside the nest 81,2% and light intensity ranged from 98,1-834,1 lux in the morning, 437,8-4014,8 lux in the afternoon, and 45,7-653,8 lux in the afternoon. Chemical parameters obtained organic matter content ranged from 1,4%-3,2% and pH ranged from 6,8-7. Vegetation that had the highest INP in each nest was Voacanga foetida, Inga edulis, Artocarpus elasticus, and Bambusa bambos, these plant species act as materials for building nest mounds and potentially as food for orange-footed scrubfowl.

Abstract

Fish are oceanic biota that are frequently utilized as signs of weighty metal contamination in waters. The purpose of this study was to determine the levels of cadmium (Cd) in tilapia from ponds in Palibelo and whether or not it is safe for consumption based on the Regulation of the Food and Drug Supervisory Agency (BPOM) No. 9 of 2022 concerning Requirements for Heavy Metal Contamination in Processed Food. Sampling was carried out by purposive sampling, at each station two fish samples were taken using floating nets. Samples were analyzed at the Health Laboratory, Testing and Calibration Center (BLKPK) of NTB Province. Data analysis was carried out by taking body parts, namely tilapia meat, then analyzing cadmium (Cd) levels using AAS. The results showed that cadmium levels in tilapia were still below the standard quality standards ranging from 0.0033-0.0057 mg/kg, with an average cadmium of 0.00465 mg/kg. Cadmium comes from household waste and modern waste carried by river currents. Environmental factors obtained temperature, pH, and salinity are in ideal conditions for the life of Tilapia fish. The conclusion is that Tilapia fish from fish farming in Palibelo is still suitable for consumption because it is still below the standard quality of 0.30 mg/kg.

Abstract

Orange-footed scrubfowl (Megapodius reinwardt) is a protected animal. Especially on the island of Lombok, one of the habitats of the orange-footed scrubfowl bird is in Tunak Montain Nature Tourism Park. The condition of the nest will influence the frequency of presence of orange-footed scrubfowl. In this regard, to enrich information in its conservation, it is necessary to carry out research on the characteristics of the nests of the orange-footed scrubfowl. The aim of this research to determine the nest characteristics of the orange-footed scrubfowl in Tunak Montain Nature Tourism Park. The method used is direct measurement and observation in the field. The results of the research show that the nest of the orange-footed scrubfowl bird is in the form of a mound of earth composed of leaves, branches, tree twigs, sand and rocks. The height of the nest mound ranges from 57-160 cm, and the diameter of the nest mound is 500-1,030 cm. The number of holes in each nest varies, namely between 5-9 holes, with a hole depth of 67-142 cm and a nest hole diameter of 30-41 cm. The dominant factors of the abiotic component of the nest that have a singular influence on the presence of orange-footed scrubfowl are distance to the river channel and number of predators. The tendency to choose a nesting area based on the results of Chi-Square analysis is influenced by five variables, namely, distance to the river, soil texture, altitude, temperature and number of predators around the nest.

Abstract

Orange-footed scrubfowl (Megapodius reinwardt) is a protected species and needs to be preserved. They build mounds using leaves, twigs, plant litter and soil. The importance of plant vegetation around the Orange-footed scrubfowl nesting area while until this research was conducted no one had examined plant vegetation in Orange-footed scrubfowl nesting area became the background of this research. The data collection method of this research is by using the plotted method. Variables in this study include plant vegetation (tree diameter, number of individuals and tree species) and environmental data including temperature, humidity and light intensity. The results showed that the vegetation of Orange-footed scrubfowl nesting area in TWA Gunung Tunak has differences in species between one nest and another, but there are still many similar species. The diversity index shows that the vegetation around the nest is not diverse, ranging from 11-15 species with high dominance evenness. The species similarity index between inside the nest and outside the nest is high. This is also influenced by environmental factors that are not too different from one nest and another. Based on the results of the research that has been done, it is concluded that the vegetation of the gosong bird nesting area in the red foot of TWA Gunung Tunak has differences in species between one nest and another, but there are still many similar species.
