Abstract

The influence of monsoonal wind to coastal upwelling mechanism which is generated by Ekman transport was studied here by analyzing wind stress curl (WSC) distribution over Java-Bali Sea waters and its surrounding area. Surface wind data were used as input data to calculate curl of wind stress in barotropic model. Confirmation with Corioli effect in the Southern Hemisphere, it could be known that negative curl value has relation with vertical motion of sea water as resulted by Ekman transport. Result of analysis showed that negative curl near coast over Java Sea which is stretching to Lombok Sea occurred in December to April when westerly wind of the North West Monsoon actives. It can be guidance and related with season of coastal upwelling in the region. Reversal condition, the occurrance of coastal upwelling in the south coast of JAva island related with the negative value of WSC that occurs since easterlies wind take place in May to August as a part of South East Monsoon episode. Generally, upwelling occurrance in the field of study is a response to the Monsoon circulation. This study with related data such as sea surface temperature, chlorophyll concetration and mixed layer depth that derived from satellite imaging data National Oceanic and Atmospheric Administration Advanced Very High Resolution Radiometer (NOAA-AVHRR), Aqua/Modis and sea viewing Wide Field-of-view Sensor(Sea WiFS) shows as magnificent confirmation pattern. So applying WSC to recoqnize upwelling zone is alternatively way as climatic approach to maps potential fertilizing of sea water in maritime-continent Indonesia.

Abstract

Penelitian ini bertujuan untuk menganalisis faktor-faktor yang memengaruhi penyerapan anggaran dengan perencanaan anggaran dan politik anggaran sebagai variabel pemoderasi pada satker Badan Penelitian dan Pengembangan Kesehatan. Jenis penelitian yang dilakukan adalah asosiatif yang bersifat kausal dengan metode survei. Populasi dalam penelitian ini adalah tim pengelola keuangan di 16 satker Badan Litbangkes. Sampel dalam penelitian ini diperoleh sebanyak 94 dengan pemilihan sampel secara purposive sampling. Data diolah dengan menggunakan analisis regresi berganda dan uji residual. Hasil penelitian ini membuktikan bahwa kompetensi sumberdaya manusia, proses pengadaan barang dan jasa, dan komitmen organisasi secara parsial berpengaruh signifikan terhadap penyerapan anggaran di satker Badan Litbangkes. Perencanaan anggaran dan politik anggaran yang merupakan variabel moderating dapat memperkuat hubungan antara kompetensi sumberdaya manusia dan komitmen organisasi terhadap penyerapan anggaran, namun perencanaan anggaran dan politik anggaran tidak dapat memperkuat hubungan antara proses pengadaan barang dan jasa terhadap penyerapan anggaran

Abstract

Preliminary observations indicated that students in Islamic senior high schools located in agro-industrial areas demonstrated limited digital literacy skills, particularly in accessing, evaluating, and utilizing digital learning resources to understand abstract biology concepts. This research aims to develop PowerPoint-based augmented reality media integrated with socio-scientific issues to enhance digital literacy. The study employed a Research and Development approach using the ADDIE model involving 19 students and one biology teacher at MA Arriyadlah Pandean, Probolinggo Regency. Data were collected through validation instruments, questionnaires, and pretest–posttest assessments, then were analyzed descriptively and inferentially using the Wilcoxon Signed-Rank Test due to the small sample size. The results showed that the media achieved very high validity (87.33%) and practicality (87.59%). Students’ digital literacy improved after implementation, indicated by a moderate N-Gain score (0.54) and significant differences between pretest and posttest scores. This study contributes an accessible AR-based biology learning medium integrated with socio-scientific issues to support digital literacy in pesantren-based education. The developed media were found to be feasible, practical, and potentially effective for contextual biology learning. However, the findings were limited to a small-scale implementation involving a single class and a single biology topic.
