Abstract

Cryptococcus neoformans isolates were previously obtained from pigeon droppings in Jakarta. This study aimed to determine another source of infection and describe the supporting niche of the fungus. The occurrence of C. neoformans was evaluated in 110 samples of decaying wood and leaves, tree hollow debris, dust, and bird droppings. Yeasts isolates were collected from 22 houses of HIV-infected patients. The isolates were identified based on culture characteristics, an assimilation test, and URA5 restriction fragment length polymorphism polymerase chain reaction. The spatial analysis was conducted in geographical information system to determine dominant house and environmental factors. Seven of the 120 isolates (5.83%) were identified as C. neoformans, corresponding to four (18.2%) houses. All isolates were from house environments of HIV-infected patients with cryptococcal meningitis. Spearman’s correlation analysis and McNemar’s test revealed a significant association between cryptococcosis in HIV-infected patients and their environment. The clinical and environmental isolates were 100% identical based on molecular techniques, indicating that the patients acquired cryptococcosis from the environment. The spatial analysis revealed that house dust, soil, and leaves were the dominant distribution factors in terms of estimating disease prevalence. This study demonstrates that the house environment is a source of infection for cryptococcosis.

Abstract

Space-based earth observation technology applicable to forest inventory and monitoring is well known in the scientific community. High-resolution satellite images form an important data source for forest mapping and change detection at regional and national scales. The value of forest change information derived from remote sensing data is significantly enhanced if this information is integrated into a spatially explicit geographic information system. Satellite-based rapid assessment was conducted to measure spatiotemporal changes in Batudulang forest over the years. The general approach to quantify change in the spatial aspect of the forest involved change detection using moderate-resolution imaging spectro-radiometer satellite-based normalized difference vegetation index. A further top–down approach using high-resolution data from Google Earth was used to complement the mapping and specifically identify areas of spatial, temporal, and thematic change on a grid basis (1×1 sq. km.). Results from change detection studies revealed that the forest area changed from 287 sq. km. in 2008 to 189 sq. km. in 2016. Visual image interpretation of high-resolution Google Earth images (2001–2013) analyzed 63 grids, of which 30 showed significant change and 33 exhibited no change.

Abstract

Education is a crucial human right for the progress of a nation, especially in the era of globalization. In Indonesia, the quality of education still faces various challenges, one of which is the role of professional and competent teachers in improving the quality of education. This study aims to explore education quality management as a strategic tool for teacher human resource development at MAN 2 Malang City. The research method used is a case study with data collection techniques through participatory observation, interviews, and documentation. The results showed that the quality standards of teachers at MAN 2 Malang City include a minimum of S1 education that is linear with the field of study taught and has educator certification. In addition, teachers are required to have religious skills that are applied in all subjects. Quality management at MAN 2 Malang City is implemented through careful planning, teacher competency tests, and training programs to improve teachers' pedagogical, social, professional, and personality qualities. The findings emphasize the importance of quality management in teachers' professional development to achieve quality education in Indonesia.
