Abstract

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.

Abstract

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.

Abstract

Serang Regency, with an area of 1,467.35 km2 in 2020 had a population of 1,622,630 people. By referring to SNI 19-3983-1995, the waste capacity produced on average is 2.25 liters per person per day, so the potential waste in Serang Regency in 2020 is around 1,212,903.7 m3 /year, while the amount of waste that can be transported to the final waste processing site (or TPA) is 98,339 m3 . Based on this data, waste services in Serang Regency have only reached 7.37%, far from the target of the Serang District Regional Policy and Strategy (Jakstrada) of 74% as stated in the Serang Regency Regulation No. 6 of 2021. On the other hand, there are still many roadside piles of waste in Serang Regency, which indicates that there is still a lack of community participation in waste management. Waste management involves several factors, including institutions or organizations, laws, regulations, management financing, technical and operational waste, as well as community attention and participation. Looking at the phenomenon, analysis of waste management factors in Serang Regency was carried out so that the dominant factors in improving waste management performance could be identified for further planning of strategies to optimize waste management, both through waste handling and waste reduction. Based on the analysis carried out using SPSS, it can be stated that factors of operational technical, organizational, legal, and regulatory, as well as factors of financing and community participation are suitable to be used as a policy combination to improve waste management performance in Serang Regency.

Abstract

One of the risks associated with climate change is carbon dioxide (CO2) emission, which can negatively affect human health and the ecosystem. The CO2 emission can lead to a decline in urban area quality that surpasses the environment's carrying capacity. This research aimed to investigate the relationship between CO2 Emissions from Transportation (X1), Household (X2), and Business Sector (X3) with the CO2 reduction of green open space (Y). The hypothesis is that there is a negative correlation between CO2 emissions from transportation, households, and businesses and CO2 reduction from green open spaces. A quantitative research design was adopted using the Slovin formula and cluster random sampling. The Normality and Homogeneity Tests are used to analyze research data. The study yielded the following results: first, the coefficient of determination (r2) = 0.003 indicates a relationship between CO2 emissions from transportation with CO2 reduction from green open space, with a 0.3% contribution. The second finding is that there is a 0.1% contribution from CO2 reduction from green open space to the CO2 emissions of households, as indicated by the coefficient of determination (r2) = 0.001. Third, a correlation of 0.1% between CO2 reduction from green open space and CO2 emissions from the Business Sector is indicated by the coefficient of determination (r2) = 0.001. Thus, using the regression equation Y = 2320.432 – 0.16X1 – 0,25 X2 – 0,007 X3, there is an overall significant relationship between CO2 emissions from transportation, CO2 emissions from households, and CO2 emissions from the business sector with the reduction of CO2 from green open space. Salah satu risiko yang terkait dengan perubahan iklim adalah emisi karbon dioksida (CO2), yang dapat berdampak negatif terhadap kesehatan manusia dan ekosistem. Hal ini dapat mengakibatkan penurunan kualitas kawasan perkotaan hingga melampaui daya dukung lingkungan. Penelitian ini bertujuan untuk mengetahui hubungan Emisi CO2 dari Transportasi (X1), Rumah Tangga (X2), dan Dunia Usaha (X3) dengan penurunan CO2 pada Ruang Terbuka Hijau (Y). Hipotesisnya adalah terdapat korelasi negatif antara emisi CO2 dari transportasi, rumah tangga, dan dunia usaha dengan penurunan CO2 dari ruang terbuka hijau. Dengan menggunakan rumus Slovin dan cluster random sampling, desain penelitian yang digunakan adalah kuantitatif. Uji Normalitas dan Homogenitas digunakan untuk menganalisis data penelitian. Penelitian ini menghasilkan hasil sebagai berikut: pertama, koefisien determinasi (r2) = 0,003 menunjukkan adanya hubungan antara emisi CO2 dari transportasi dengan penurunan CO2 dari ruang terbuka hijau, dengan kontribusi sebesar 0,3%. Temuan kedua, terdapat kontribusi penurunan CO2 dari ruang terbuka hijau terhadap emisi CO2 rumah tangga sebesar 0,1% yang ditunjukkan dengan koefisien determinasi (r2) = 0,001. Ketiga, korelasi sebesar 0,1% antara penurunan CO2 dari RTH dengan emisi CO2 dari Dunia Usaha ditunjukkan dengan koefisien determinasi (r2) = 0,001. Dengan demikian, dengan menggunakan persamaan regresi Y = 2320.432 – 0.16X1 – 0,25 X2 – 0,007 X3, secara keseluruhan terdapat hubungan yang signifikan antara emisi CO2 dari transportasi, emisi CO2 dari rumah tangga, dan emisi CO2 dari dunia usaha dengan penurunan emisi CO2 dari ruang terbuka hijau.

Abstract

This study aims to analyze the threat of edge effects on endemic animal populations due to the presence of causeways in the TNGHS corridor habitat. Indicators of the occurrence of edge effects are characterized by the further distance of wildlife populations from sources of disturbance such as noise, light, and frequency of human activity mechanisms. Belt transect research method for population study and distribution of Javan Gibbon and Surili. Intensive Point Account (IPA) to measure the diversity index of bird species and Javan eagles. Encounter Rate is used for animal distribution studies. Results On the observation transect made along 3 km, the population density of Javan Gibbons was obtained 0.114 ind/ha, Surili 0.024 indv/ha, and Monkey 0.028 indv/ha. Bird species diversity index in 3 habitat patches each Purasari H'= 2.78 with 38 species; Garehong with 27 species, and Corridor H'= 3,087 with 27 species. The similarity of species is that there are only 7 species of birds found in the 3 habitats of the patch. As a result of primate population density and burng species similarity, it can be concluded that the cross-corridor access road area has experienced an edge effect and tends to be a bottle-neck area for the distribution of animals, especially primates.
