Pengaruh jenis Spesies Pillaring Agent Logam Si dalam proses Pilarisasi Bentonit Alam
Full text linkAbstract—The pillarization process of natural bentonite from Pacitan, East Java has been carried out using the metal species Si in Na-silicate and TEOS. The pillarization process is carried out using direct pillarization and indirect pillarization methods. In this research, the number of moles of metal pillaring agent used was 5 mmol/gram bentonite. The pillarization process is carried out by mixing the natural bentonite suspension and pillaring agent at a temperature of 80oC and stirring for 5 hours using a hot plate stirrer. Pillars were formed in the calcination and oxidation stages at a temperature of 500oC using N2 and O2 gas flows for 1 hour and 5 hours respectively. The resulting material was characterized using the FTIR spectroscopy method, X-ray diffraction and N2 gas adsorption using the BET method. The characterization results show that TEOS species can form better and more homogeneous pore structures compared to silicate species. The direct pillarization method provides better and more homogeneous pillar heights compared to the indirect pillarization method. However, the pore size obtained is still on the micropore size scale observed using the N2 gas adsorption method with the BET method.

Hubungan Antara Lingkungan Belajar yang Mendukung Kebutuhan dan Perilaku Sabotase Diri Akademik pada Siswa Form Two di Meru County, Kenya
Full text linkAcademic self-sabotaging behavior is a prevalent problem among Form Two students in Kenya, being linked to lower academic achievement, academic anxiety, academic stress, and poor mental health. Existing research has consistently linked basic psychological needs (BPN) satisfaction to less academic self-sabotaging behavior. Despite this, there is a relative dearth of studies exploring this area in the Kenyan context. Therefore, the current study examined how basic psychological needs-supportive learning environment relate to academic self-sabotaging behavior, with self-determination theory (SDT) as the theoretical basis, and a convergent parallel mixed-methods research design. The quantitative study sample comprised 400 students (215 boys; 185 girls) drawn using proportionate stratified and simple random sampling. The qualitative study sample included 20 students drawn using purposive criterion sampling. Data for quantitative study was collected using Basic Psychological Needs Satisfaction and Frustration Scale (BPNSFS; Chen et al., 2015) and Academic Self-Handicapping Scale (Midgley & Urdan, 2001). Qualitative data collection tools was a semi-structured interview schedule. Study results revealed a weak, negative and statistically significant correlation between needs-supportive learning environment and academic self-sabotaging behavior (r(396) = - .14; p < .01). Qualitative findings complemented these results, revealing that a learning environment that supported students’ needs of autonomy, competence, and relatedness promoted high level of adaptive learning behaviors. The study recommends that schools should promote an autonomy-supportive school environment that meets students’ basic psychological needs (BPN) to reduce academic self-sabotaging behavior.Perilaku sabotase diri akademik merupakan masalah yang lazim di kalangan siswa Form Two di Kenya, yang dikaitkan dengan prestasi akademik yang lebih rendah, kecemasan akademik, stres akademik, dan kesehatan mental yang buruk. Penelitian yang ada secara konsisten mengaitkan kepuasan kebutuhan psikologis dasar dengan perilaku sabotase diri akademik yang lebih sedikit. Meskipun demikian, terdapat kelangkaan relatif studi yang mengeksplorasi area ini dalam konteks Kenya. Oleh karena itu, studi ini meneliti bagaimana lingkungan belajar yang mendukung kebutuhan psikologis dasar berhubungan dengan perilaku sabotase diri akademik, dengan self-determination theory (SDT) sebagai dasar teoritis, dan desain penelitian metode campuran paralel konvergen. Sampel studi kuantitatif terdiri dari 400 siswa (215 laki-laki; 185 perempuan) yang diambil menggunakan random sampling sederhana dan stratifikasi proporsional. Sampel studi kualitatif mencakup 20 siswa yang dipilih menggunakan sampel kriteria purposif. Data untuk studi kuantitatif dikumpulkan menggunakan Basic Psychological Needs Satisfaction and Frustration Scale (BPNSFS; Chen et al., 2015) dan Academic Self-Handicapping Scale (Midgley & Urdan, 2001). Alat pengumpulan data kualitatif adalah jadwal wawancara semi-terstruktur. Hasil studi mengungkapkan korelasi yang lemah, negatif dan signifikan secara statistik antara lingkungan belajar yang mendukung kebutuhan dan perilaku sabotase diri akademik (r(396) = - 0,14; p < 0,01). Temuan kualitatif melengkapi hasil ini, mengungkapkan bahwa lingkungan belajar yang mendukung kebutuhan siswa akan otonomi, kompetensi, dan keterkaitan mendorong perilaku belajar adaptif tingkat tinggi. Studi ini merekomendasikan bahwa sekolah mempromosikan lingkungan sekolah yang mendukung otonomi yang memenuhi kebutuhan psikologis dasar siswa untuk mengurangi perilaku sabotase diri akademik

Peran Indonesia dalam Implementasi Prinsip Responsibility to Protect dan Non-Refoulement dalam Krisis Kemanusiaan Etnis Rohingya
Full text linkThe humanitarian crisis experienced by the Rohingya ethnic group in Myanmar has raised a dilemma in the international legal order, between the principle of state sovereignty and international obligations to protect human rights. This article aims to analyze Indonesia's contribution to the implementation of the Responsibility to Protect (R2P) and non-refoulement principles as two main norms in modern international law, especially in the context of handling Rohingya refugees. With a normative legal approach and literature study of international legal documents, UN reports, and Indonesian foreign policy, this study shows that although Indonesia is not a state party to the 1951 Convention, its practices show the application of the principle of non-refoulement as part of jus cogens. Within the R2P framework, Indonesia plays a role through multilateral diplomacy in ASEAN and the United Nations, as well as initiatives such as Formula 4+1. However, the limitations of the UNSC in acting due to political vetoes and ASEAN's principle of non-intervention are the main obstacles to the collective implementation of R2P. This article concludes that Indonesia's success as a regional actor in this crisis requires a proactive diplomatic strategy, encouraging reform in the UNSC, and consistency in making humanitarian values a priority over political interests. It is hoped that these findings can provide academic contributions to the study of international law and the role of Indonesian diplomacy in handling contemporary humanitarian crises
