Paparan karbon dioksida (CO2) di Tempat Pemrosesan Akhir Sampah (TPAS) berpotensi menimbulkan gangguan fisiologis pada pekerja akibat akumulasi gas dari dekomposisi sampah organik. Penelitian ini bertujuan menganalisis risiko kesehatan lingkungan akibat paparan CO2 pada pekerja TPAS Manggar, Kota Balikpapan, menggunakan pendekatan Analisis Risiko Kesehatan Lingkungan (ARKL...
This article scientifically and methodologically analyzes the role and importance of lexical wealth in the formation of students' speech competence in the process of teaching the mother tongue. Methodological approaches and a system of practical exercises aimed at developing oral and written speech competence based on systematic work with explanatory, spelling and orthoepic...
Optically addressable spin systems have been widely studied for quantum-sensing applications. In this work, we demonstrate that photogenerated spin-correlated radical pairs in certain flavoproteins, cryptochrome and improved light–oxygen–voltage protein, can be manipulated by radio waves. This capability enables magnetic field sensing and spatial modulation of photoluminescence...
Intracellular calcium (\(\:C{a}^{2+}\)) signaling at synapses is fundamental to understanding how the brain processes information, learns and stores memories. However, achieving precise control over calcium dynamics at the level of individual synapses remains a major challenge in neuroscience. Recent advances in calcium-permeable channelrhodopsins (CapChRs) provide a promising...
This study is motivated by the importance of internal communication in improving employee performance within public sector organizations. Several issues were identified at the Department of Transportation, Communication and Informatics of Tasikmalaya Regency, including delays in information delivery, limited communication interaction between leaders and employees, and the lack of...
This study aims to analyze and compare the pedagogical paradigms in two Arabic textbooks, namely Kunuz Ta’līm al-Lugah al-'Arabiyyah volume 1 and Al Arabiyyah Baina Yadaik volume 1, to understand the relationships among learning approaches, material design, activities, and evaluation systems. The difference between structural and communicative approaches is seen as a reflection...
Heavy metal pollution is a serious environmental problem that affects soil fertility and microbial activity. Soil microorganisms play a key role in nutrient cycling, organic matter decomposition, and ecosystem stability. This study examines the effects of heavy metals on soil microbial communities and biochemical processes. The findings indicate that cadmium, lead, mercury, and...
Diamonds crystallise from fluids/melts circulating in the Earth’s mantle. Analysis of these fluids is possible if they remain entrapped in the diamond during growth, but such fluid inclusions are rarely observed in gem-quality stones. We investigated thin films surrounding mineral inclusions, previously described as silicic fluid rims containing Si2O(OH)6 and Si(OH)4, in gem...
Industri pembangkit listrik merupakan sektor dengan tingkat risiko operasional yang tinggi akibat kompleksitas sistem, penggunaan material berbahaya, serta aktivitas operasional yang berlangsung secara kontinu. Namun, evaluasi kinerja keselamatan pada banyak organisasi masih didasarkan pada indikator frekuensi kejadian, yang belum mampu merepresentasikan tingkat risiko secara...
Shipping is a transnational sector competing for energy on a global market and needs effective policies to decarbonize. Here we assess energy transitions under different shipping policies using a sector-coupled global energy system model and connected life-cycle environmental impacts. We find that postponed International Maritime Organization’s ‘net-zero framework’ could increase...
