The objectivity of research is to develop the instrument of environmental sensitivity which have influence to increase environmental view for PAUD teachers. Research and development method taken through by need analysis, instrument draft, validation, and wide test of the instrument. Result, there are build a standardize of instrument through two cycles validation about 10 items instrument from 20 items. Also with the one factor of varian analysis in threes areas in Jakarta such as, Jatinegara District, Pasar Minggu District, and Grogol District, that F value 2,94 (p>0,01), there are not significant difference (Ho rejected). Based on that, a instrument have taken to recommendation. Keywords: Environmental sensitivity, Environmental View, PAUD teacher

Javan gibbon is one of an endemic species of Java with kind of unique vocalizations. Supported by a study which showed that every individual has the different anatomy vocal tract that will produce a different sound. Character vocalizations formed from the structure of vocalizations vary between individuals would be the identity of an individual so that there will be effective communication between the giver signal to the receiver. The objective of research is to find out the structure variation of Javan gibbon vocalizations.The research was accomplished in August-September 2015 at the Petungkriyono Protected Forest, Pekalongan, Central Java. The method used is the Focal Continuous sampling. Ratio coefficient of variation within and between female, indicates that the variable vocalizations vary between individuals, and the correct rate of individual identification yielded bydiscriminant function analysis using variable vocalizations was satisfactory (94,4%). Variable vocalization differentiatoris total great call duration (8,99-13,53 s), total great call duration excluding termination phase, duration pre-trill phase, duration introduction note (0,147-0,612 s), frequency range introduction note (408,54-1209,6 Hz), minimal frequency introduction note, maximal frequency introduction note, minimal frequency second trill note, minimal frequency at end of trill note, and minimal frequency range in trill. These vocalizations potentially allow individual recognition of animals.

KEPADATAN POPULASI MAMALIA DARAT KARNIVORA DI CAMP LEAKEY KAWASAN TAMAN NASIONAL TANJUNG PUTING, KALIMANTAN TENGAH: Population Density Of Terrestrial Mammalian Carnivore In Camp Leakey, Tanjung Puting National Park, Central Borneo Mandiri, Siwi Arthapati; Sukandar, Paskal; Istiadi, Yossa

Borneo has wide land that support high biodiversity. One of them is Tanjung Puting National Park (TPNP), which have biodiversity such as terrestrial mammalian carnivore. Carnivore has a role to maintain its ecosystems. But, there are no data for population density of terrestrial mammalian carnivore. The object of this research is to find out population density of terrestrial mammalian carnivore in Camp Leakey, TPNP, Central Borneo. This research accomplished in September-October 2015 in Camp Leakey. Using line-transect sampling. Data collection was accomplished at 18.00-24.00 Central Indonesian Time (WITA) on eight transects with three times replication by direct surveys and indirect surveys. This research has obtained five species, malayan sun bear (Helarctos malayanus), sunda clouded leopard (Neofelis diardi), leopard cat, and group of civet, like small-toothed palm civet (Arctogalidia trivirgata) and asian palm civet (Paradoxurus hermaphroditus). Population density of each species from the highest to the lowest is 13,5 Individual of leopard cat/km2, 9,84 Individual of malayan sun bears/km2, 4,31 Individual of sunda clouded leopard/km2, and 3,65 Individual of civet/km2. Malayan sun bears, sunda clouded leopards and civets prefer to be in land forest. Leopard cats prefers to be in transition forest.

Knowledge is an important factor in appearing care. As well as knowledge of high school student around Pulau Pramuka in order to bring conservation principle in the area. The aim of this research was to find out the correlation between environmental knowledge and coral reefs conservation concern. This research was held on February 2015 at SMAN 69 Jakarta. The research method used was descriptive with survey technique bycorrelational study. The sample reserach was 43 high school students grade X. The regression model was . Coefficient correlation was 0,395 that means there was low correlation between environmental knowledge of high school student and their care about coral reefs conservation. Environmental knowledge about coral reefs conservation gave contribution of 15,60% on high school student care about coral reefs conservation. The research result concluded that there was correlation between environmental knowledge and coral reefs conservation concern.

This study aims to determine the effect of educational technology competence, transformational leadership and self-efficacy on teachers' professional commitment to multicultural education in public elementary schools in Grogol Petamburan District, West Jakarta. This study uses a survey method with a quantitative approach using path analysis techniques. The data for this study were obtained by questionnaire. The survey involved 173 certified teachers from 25 public elementary schools as samples using simple random sampling techniques. The results of the study showed: 1) There is a positive direct effect of educational technology competence on teachers' professional commitment to multicultural education with a path coefficient value of 0.278 and a calculated t coefficient value of 4.311, 2) There is a positive direct effect of transformational leadership on teachers' professional commitment to multicultural education with a path coefficient value of 0.306 and a calculated t coefficient value of 4.76, 3) There is a positive direct effect of self-efficacy on teachers' professional commitment to multicultural education with a path coefficient value of 0.286 and a calculated t coefficient value of 4.477. Therefore, the three calculated t coefficient values ??are greater than the t table value, so H0 is rejected and Ha is accepted, namely that educational technology competence has a direct positive effect on teachers' professional commitment to multicultural education, transformational leadership has a direct positive effect on teachers' professional commitment to multicultural education, and self-efficacy has a direct positive effect on teachers' professional commitment to multicultural education.

This research aims to study the design of the ecological corridor management pattern of Gunung Halimun Salak National Park (TNGHS) through the identification of population and distribution of conservation species, edge effect of road access within the corridor, preservation mitigation, status of non-conservation species, and assessment of land-use-based ecotourism. The methods used include Belt transect, hypothetical transect, Intensive Point Account (IPA), and descriptive survey techniques. The research was conducted from September to December 2023. The results showed that the population density of Javan Gibbon was 0.114 indv/ha, Surili was 0.024 indv/ha, which is very low compared to the population density of TNGHS, 26 non-conservation bird species, and 1 endemic species, the Javan Gibbon. The edge effect is caused by the frequency of vehicles passing through the corridor. The hypothetical transect shows that the land use allocation for tea plantations is the target of ecotourism, and agricultural land use supports the product. The model design emphasizes the creation of protection zones for primates and Javan Eagles in terms of mobilization and migration, mitigation of vehicle crossings during the day, as well as the initiation of ecotourism based on non-conservation species and landscape characteristics. In conclusion, the ecological corridor management modeling includes accommodating the protection of endemic and rare animals, monitoring non-conservation bird species, conservation mitigation through vehicle frequency control, limited ecotourism development with a natural orientation, and agricultural products. Scientifically the contribution of this research is to explain the implications of island geography theory in the sustainability of endemic species in metapopulations to avoid genetic flow deviations.
