Abstract

China's Belt and Road Initiative (BRI), launched in 2013, aims to improve global connectivity through infrastructure projects. In Indonesia, the Jakarta-Bandung High Speed Rail (KCJB) project is an important part of the BRI, with the aim of speeding up travel time, improving connectivity, and boosting regional economic growth. However, the project faces challenges such as land acquisition, community resistance, and the risk of economic dependence on China. Using the theoretical approaches of Dependency, International Political Economy, and National Interest, this study highlights the opportunities and risks of this project in the context ofVIndonesia-China bilateral relations. The analysis shows that the KCJB can deliver substantial benefits, but requires risk management, effective technology transfer, and an inclusive approach to ensure the project's success and sustainability.

Abstract

Time is a significant and massive worry in behaviour that causes difficulties amongst instructors and learners in ensuring an effective process of teaching and learning in open and distance learning (ODL) environment. This study aimed to identify instructors’ and learners’ ability to allocate time in ODL. The study was conducted with 320 respondents, and the instrument used was questionnaires. The results showed that ODL instructors and learners were challenged with many obstacles to prioritizing tasks and allocating time accordingly in their teaching and learning. A close inspection of the role of time management is much required. The most reported challenges were managing the academic schedule on ODL and multitasking while teaching and learning on ODL. Lastly, it was deemed unnecessary to have additional time to satisfy the expectations of ODL. It was found that both instructors and learners from public and private higher education institutions needed effective educational practices to succeed in ODL and blended learning. In short, time allocation in prioritizing tasks is still an obstruction to achieving effective and balanced teaching and learning system with ODL that satisfies the desire of the instructors and learners. This research suggests investigating social, cognitive, teaching and emotional presence to successfully conduct the teaching and learning process.

Abstract

Uji stabilitas merupakan tahapan penting dalam pengembangan sediaan farmasi untuk memastikan mutu, keamanan, dan efektivitas produk selama masa simpan. Nanoemulsi menjadi salah satu bentuk sediaan cair yang banyak dikembangkan karena mampu meningkatkan kelarutan, bioavailabilitas, serta kestabilan zat aktif yang bersifat lipofilik. Kajian ini bertujuan untuk meninjau berbagai penelitian terkait pengujian dan peningkatan stabilitas sediaan nanoemulsi berbasis bahan alam dengan menyoroti pengaruh bahan aktif, jenis surfaktan dan kosurfaktan, serta kondisi penyimpanan terhadap kestabilan sistem. Metode yang digunakan adalah telaah pustaka dari berbagai penelitian terbitan sepuluh tahun terakhir yang membahas formulasi dan uji stabilitas nanoemulsi bahan alam. Data yang dianalisis mencakup parameter fisik seperti ukuran droplet, indeks polidispersitas, viskositas, pH, dan kejernihan, serta metode pengujian stabilitas seperti freeze thaw, centrifugation, dan heating cooling test. menunjukkan bahwa kombinasi surfaktan nonionik Tween 80 dengan kosurfaktan PEG 400 atau gliserin merupakan perlakuan paling efektif dalam meningkatkan kestabilan fisik dan kimia nanoemulsi berbasis bahan alam. Sistem nanoemulsi yang dibuat menggunakan metode berenergi tinggi, khususnya ultrasonikasi, menghasilkan ukuran droplet dengan indeks polidispersitas rendah kurang dari 0,5, sehingga mampu menekan terjadinya koalesensi dan flokulasi selama penyimpanan. Selain itu, penyimpanan pada suhu ruang dan penggunaan bahan aktif yang mengandung senyawa antioksidan tinggi terbukti memperlambat oksidasi lipid dan mempertahankan kestabilan nanoemulsi dalam jangka panjang.
