The Javan rhino (Rhinoceros sondaicus) is one of the most threatened mammals on Earth. The only remaining individuals live as part of a small population isolated in a single protected area, Ujung Kulon National Park, Java, Indonesia. Despite almost a century of studies, little is known about the factors that affect Javan rhino demography and distribution. National park officials require such information to identify conservation strategies and track the success and failures of these efforts; translocating selected individuals to establish a second population has been considered, but the risks must be weighed. We show that the 2013 global population of Javan rhinos was 62 individuals, which is likely near the site's carrying capacity. Our analysis of rhino distribution indicates that tsunamis are a significant risk to the species in Ujung Kulon, justifying the risks of establishing additional populations. Continued individual-based monitoring is needed to guide future translocation decisions.

The research objective is multimedia whiteboard animation's impact on understanding and completing the preparation of non-basic education (non-pendas) students' scientific work at UPBJJ UT Semarang. The research objects are 123 non-pendas students taking scientific work courses at UPBJJ UT Semarang, which are explored using a questionnaire. The research used a qualitative analysis of the completion of the preparation of scientific papers using the Whiteboard Animation learning media. The learning process showed the average good and very good answers of 63.41% in the high category, 68.09% in the very high category for content of learning materials, and 60.16% in the high category for the impact of Whiteboard Animation. Overall, students' perception of the Whiteboard Animation-based learning process is very effective, proven by: 1) 85 students (69.10%) uploaded their scientific work before the lecture was over, 2) the average value of students' perceptions for all indicators was high. The limitations are the difficulty of controlling respondents because the experiment was carried out by students online. The factors assessed are only learning media. To determine whether students will pass or fail, it is not the tutor in charge of this course but the students. Even though students have uploaded scientific papers, they cannot determine it.
