PAUD teachers experience problems and difficulties when developing appropriate learning media when teaching. This research aims to develop Tri Kaya Parisudha's Animated Video Media on the My Environment Theme for PAUD. This type of research is developed using the ADDIE model. The product was tested by 1 learning content expert, 1 instructional design expert, 1 learning media expert, as well as with research subjects 3 individual trial students, 6 small group trial students, and an effective test using 19 students. The data obtained is quantitative data by collecting data using a questionnaire/questionnaire and an observation questionnaire (non-test). The data analysis technique used is quantitative descriptive analysis and inferential statistics. The study's results, firstly, the design of animated video media using the ADDIE development model with the assessment results by design experts with a very good percentage. Second, the validity of the animated video media shows the results of the validity according to the experts and research subjects having good and very good categories so that the developed product is feasible to use. Third, the effectiveness of video animation media based on the results of the t-test shows that the video animation media based on Tri Kaya Parisudha is effectively applied to the theme of my environment in group B PAUD children.

This study aimed to determine the relationship between academic stress and academic procrastination in STIKES Notokusumo Yogyakarta students. The subjects of this study were 134 students of the Level 2 nursing education program from 4 different classes. This study used a quantitative data collection method using measuring devices in the shape of an academic procrastination scale and an academic stress scale. The Pearson Product Moment Correlation method of data analysis was employed in this investigation. According to the study, academic stress and procrastination have a significant inverse association. This is demonstrated by the correlation coefficient (r), which is -0.182 and has a significant level of 0.035 (p 0.05). This indicates that learning procrastination increases with reduced learning stress levels, while decreasing learning stress levels increases learning procrastination. The effective ratio of academic procrastination and academic stress is 3.3%, which means 3.3% of academic stress can reduce the occurrence of academic procrastination, while other behaviors are impacted by things like self-control or poor time management, resulting in delays. The findings of this study can be applied to student education to improve motivation among students. Other factors that should have been looked at in this study can be added by future researchers. Abstrak Memahami hubungan antara stres akademik dan penundaan akademik siswa STIKES Notokusumo Yogyakarta menjadi tujuan dari studi ini. Subyek penelitian ini adalah 134 mahasiswa program pendidikan keperawatan Tingkat 2 dari 4 kelas yang berbeda. Penelitian ini menggunakan metode pengumpulan data kuantitatif dengan instrumen berupa skala prokrastinasi akademik dan skala stres akademik. Teknik analisis data yang digunakan dalam penelitian ini adalah teknik Korelasi Pearson Product Moment. Berdasarkan hasil analisis, ditemukan adanya hubungan negatif yang signifikan antara stres akademik dengan prokrastinasi akademik. Hal ini ditunjukkan dengan koefisien korelasi (r) = -0,182 dengan nilai signifikansi 0,035 (p < 0,05). Artinya semakin rendah stres belajar maka semakin tinggi prokrastinasi belajar, sebaliknya semakin tinggi stres belajar maka semakin rendah prokrastinasi belajar. Rasio efektif prokrastinasi akademik dan stres akademik adalah 3,3% yang berarti 3,3% stres akademik dapat mengurangi terjadinya prokrastinasi akademik, sedangkan sisanya dipengaruhi oleh faktor lain seperti pengendalian diri atau manajemen waktu yang kurang baik, sehingga terjadi keterlambatan. Rekomendasi penelitian ini dapat digunakan sebagai dasar pelatihan siswa untuk meningkatkan motivasi belajar siswa. Peneliti selanjutnya dapat menambahkan variabel lain yang tidak diteliti dalam penelitian ini.

Herein, we update the diagnosis and description of the genus Krantzolaspina Datta & Bhattacharjee and provide a list of the three valid species including new combinations and synonyms, as follows: 1) Krant-zolaspina angustatus (Ishikawa, 1987) comb. nov. (= Indutolaelaps jiroftensis Hajizadeh et al., 2017 syn. nov.),2) K. rebatii Datta & Bhattacharjee, 1989 and 3) K. solimani (Metwali, 1983) comb. nov.Finally, we re-describe K. angustatus (Ishikawa, 1987) comb. nov. based on the holotype from Japan, voucher specimens from Iran and additional females that we found in soil samples from oil palm planta-tions in Sumatra, Indonesia.

Indonesia’s biodiversity is at risk due to large forest areas being transformed into rubber and oil palm monoculture plantations. The effects of this land-use change on local fauna have been studied in a variety of organisms, including invertebrates from leaf litter and soil habitats. Litter and soil organisms are important drivers of essential ecosystem functions, such as nutrient cycling and carbon sequestration, which are impacted heavily by monoculture plantations. Pseudoscorpions (Arachnida: Pseudoscorpiones) are predatory arthropods in such litter and soil habitats and are an ubiquitous, although typically not very abundant, component of the soil animal food web. Since virtually nothing is known on their functional role diversity in tropical soil food webs, this study aims at contributing filling this gap of knowledge. We studied the impact of the conversion of rainforest into rubber and oil palm plantations on the density and diversity of pseudoscorpions in two landscapes of Jambi province, Sumatra, Indonesia, and applied stable isotope analysis to investigate changes in their trophic niches. Among 266 sorted individuals, only one described species was recorded, while the others were sorted to a total of nine morphospecies. Pseudoscorpions in the study region predominantly colonized mineral soil rather than the litter layer. As expected, the density declined from rainforest to rubber (-83%) and oil palm (-87%), and the number of species declined from rainforest to rubber (-37%) but in particular to oil palm (-47%). The density in riparian areas was five times lower than in non-riparian sites, however, species richness was almost the same. Further, the community composition of pseudoscorpions differed between land-use systems and landscapes; no species was present across all land-use systems, and the majority of species was only present in one land-use system indicating high habitat dependence. Stable isotope analysis suggested that the pseudoscorpion community shifted from species associated with the detritus-based energy channel in rainforest to species associated with the plant-based energy channel in monoculture plantations, indicating shifts in the use of basal resources by the soil community cascading up into predators. Overall, the results indicate that tropical pseudoscorpion communities comprise high-level predators that prefere to inhabit soil rather than litter and respond sensitively to land-use change. Due to this sensitivity, pseudoscorpion abundance may serve as bioindicator for ecosystem changes in the tropics. To mitigate negative effects of changes in land use in tropical ecosystems on cryptic and unexplored soil biodiversity, reduced herbicide use resulting in increased understory vegetation and mulching practices might be adopted.

A new species of blattisociid mites Lasioseius orangrimbae n. sp., that belongs to the floridensis-group, is described based on females and males from litter and soil samples of secondary rainforest in Sumatra, Indonesia., Acarologia, 60, 338-352

Three species from the family Oonopidae are newly described from leaf litter habitats in Sumatra, Indonesia based on male and female morphology. All three species belong to the genus Aposphragisma Thoma, 2014: Aposphragisma globosum sp. n., Aposphragisma jambi sp. n., and Aposphragisma sumatra sp. n.
