Abstract: Carbon dots (CDs) have been widely used in various applications, one of them being metal ion sensing. Synthesizing CDs with sensing characteristics is influenced by two factors, i.e., precursor and dopant agent. This study aims to use bilimbi (Averrhoa bilimbi) with N, N-dimethylformamide (DMF) as a nitrogen source to synthesize CDs via the hydrothermal method. The result of hydrothermal showed significant colors of CDs with and without the presence of nitrogen, and these behaviors were also confirmed by the differential absorption of the CDs, with λmax of absorption at 291 nm. FTIR spectra confirmed the presence of functional groups related to CDs, such as C-H, C=H, C=N, C=O, C-O-C, and NH2. Meanwhile, emission spectra displayed fluorescent emission at λmax 495 nm (DMF 2%) and 491 nm (DMF 4%). The ion metal sensing test showed that these two samples with 2% and 4% of DMF were sensitive to Fe3+ and Hg2+ sensing. These characteristics concluded that NCDs from bilimbi juice via hydrothermal method were able in sensing metal ions, such as Fe3+ and Hg2+.Abstrak: Karbon dots (CDs) telah banyak diterapkan pada berbagai penggunaan, salah satunya adalah sebagai alat pendeteksi ion logam. Sintesis Cds dengan kemampuan mendeteksi dipengaruhi oleh dua faktor, yaitu prekursor dan agen dopant. Penelitian ini bertujuan untuk menggunakan asam belimbing wuluh (Averrhoa bilimbi) dengan penambahan N, N dimetilformamida (DMF) sebagai sumber nitrogen sebagai bahan sintesis CDs melalui metode hidrotermal. Hasil hidrotermal menunjukkan perbedaan emisi warna dari CDs dengan dan tanpa penambahan DMF, dan karakteristik ini juga ditunjukkan dengan adanya perbedaan penyerapan panjang gelombang maksimum (λmax) di 291 nm. Spektra FTIR juga mengkonfirmasi adanya gugus fungsi terkait dengan CDs, seperti C-H, C=H, C=N, C=O, C-O-C, dan NH2. Sementara itu, emisi spekra menunjukkan emisi fluorosensi pada λmax sebesar 495 nm (DMF 2%0, dan 491 nm (DMF 4%). Pendeteksian ion logam pada kedua sampel sensitif pada ion Fe3+ dan Hg2+. Karakteristik ini menyimpulkan bahwa NCDs dari jus asam belimbing dapat digunakan sebagai alat pendeteksi ion logam dalam air, khususnya pada ion logam besi dan merkuri.

Printed newspaper is one of the print-based media published daily in large quantities. The focus of this research is to remove the ink from used newsprint with alkaline treatment by using ultrasound sonochemistry method. Newsprint sheets collected were characterized by mechanical and morphology tests using FT-IR, XRD, tensile test and SEM. FT-IR spectra analysis shows the absorption of C=C functional groups as the main components of newspapers at 1427 and 1635 cm-1 wavelengths. The treatment with alkaline solution increased the mechanical strength properties of paper. SEM morphology analysis result shows that the surface of paper becomes more rough after ultrasound-alkaline treatment compared to paper without ultrasound treatment (conventional treatment). The crystallinity value decreased with alkaline treatment. The longer the ultrasound duration was, the lower the crystallinity degree became.

Abstract: Carbon dots have gained much interest due to their outstanding optical and electrical properties, making them useful for a wide range of applications. Here Empty fruit bunch (EFB) biochar was used as a carbon source in a straightforward, environmentally friendly, and reproducible hydrothermal method for producing carbon quantum dots. In this study, the role of the hydrothermal process was seen and studied by comparing the shape and fluorescence. Exciting results from HRTEM show that the carbon quantum dots in the sample are 4 nm in size. The obtained CD emits bright blue luminescence, and the absorption peak of the carbon dots was observed in the UV region with maximum absorption at 205 nm and 322 nm. The light CD shows an intense sky blue color upon illumination by a UV-light source at 365 nm. The intensity of the photoluminescence (PL) spectra sharply increases with decreasing concentration of carbon dots. Meanwhile, the CD exhibited excitation-dependence, photo-stability, and well dispersibility. These results suggest that the present CD are potential applications in optoelectronics and imaging.Abstrak: Karbon dots telah menarik banyak perhatian karena sifat listrik dan optik yang luar biasa, sehingga dapat digunakan untuk berbagai aplikasi.

The development of Si-based materials has attracted increasing attention, particularly for application in semiconductors, batteries, sensors, and optical technology. Silicon has abundant availability, high energy storage capacity, and low work potential. However, it faces compatibility challenges due to its low electrical conductivity and extremely small magnetic susceptibility. This research aimed to investigate the influence of Co dopants on the structure, morphology, electrical conductivity, and magnetic susceptibility of silicon. Silicon was synthesized using the magnesiothermic reduction method, and silicon was modified with Co metal dopants at 0.1% and 0.5% concentrations through the impregnation method. XRD analysis results showed that Si, 0.1% Co/Si, and 0.5% Co/Si exhibit silicon diffraction patterns at 2θ = 28.42º; 47.28º; 56.11º; 69.13º; and 76.36º. The morphology of Si and Co/Si revealed a rough, uneven, and porous surface with particles appearing spherical. Electrical conductivity increases with Co concentration: Si = 1223 µS/cm, 0.1% Co/Si= 1376 µS/cm, and 0.5% Co/Si= 1529 µS/cm. Magnetic susceptibility measurements indicated that Si, 0.1% Co/Si, and 0.5% Co/Si are paramagnetic at a range of 1.18 x10-6 to 1.25 x10-5 SI. These characterization results confirmed that the modification with Co dopants can enhance the magnetoelectric properties of silicon.

Introduction: The greatest disadvantage of silicone soft denture liner (SDL) materials is the difficulty in keeping them clean due to their incompatibility with conventional denture cleaning solutions. As a result, chemical methods are often recommended as effective alternatives to mechanical cleaning. Natural products have emerged as promising substitutes for synthetic chemical agents. Origanum vulgare, in particular, has shown significant antifungal activity against Candida albicans. This study aims to analyze the effect of incorporating Origanum vulgare gel on auto-polymerized SDL materials, focusing on its impacts on the inhibition zone of Candida albicans over varying usage durations and concentrations. Methods: The antifungal activity was evaluated using the disc diffusion method. The samples were divided into three groups: (1) SDL without antifungal agent addition, (2) SDL with nystatin addition, and (3) SDL with Origanum vulgare gel addition. Data were analyzed using one-way ANOVA and Dunnett’s T3 for usage duration of 7 and 14 days. Results: The addition of Origanum vulgare gel showed significant antifungal activity, with MIC (3.12%) and MFC (6.25%). One way ANOVA analyses the inhibition zone of Candida albicans was significantly affected by the usage duration (7 and 14 days), with p<0.001 respectively. Post-hoc analyses using Dunnett's T3 test for the groups at 7 days and 14 days revealed significant difference in the antifungal effect between each group with MIC and MFC. Conclusion: Nystatin was found to be less effective than Origanum vulgare gel in inhibiting the growth of C. albicans. The addition of Origanum vulgare Gel at a concentration of 6.25% to auto-polymerized silicone SDL is recommended, as it effectively inhibits the growth of Candida albicans for up to 14 days.

The detection of amoxicillin has been successfully carried out using C-dot fluorescence probes made from d-glucose and urea. The fluorescence probe has an intense bright blue emission under UV light at 395 nm and and depends on the excitation and depends on the excitation. Raman studies successfully showed a D peak at 1381 cm-1 and a G peak at 1586 cm-1 associated with graphitic and amorphous structures. The absorption peaks in UV-vis spectroscopy confirm transitions at 275 nm (π → π*) and 322 nm (n → π*) with the presence of conjugated C=C and carbonyl (C=O) functional groups. The results of the fluorescence test show a bright blue color, with its intensity measured at an excitation of 365 nm. This can be attributed to nitrogen incorporation on the surface of the C-dots derived from urea, resulting in a quantum yield of 54%. This fluorescence probe is highly sensitive in detecting amoxicillin, as evidenced by the successful detection of AMX at concentrations of 10–30 μM and a resulting LOD of 5.75443×10−7 nM. The microstructure shows a uniform size of C-dot nanoparticles, and C-dot modeling was created. C-dot probes have an LOD of 5.75443×10−7 nM, indicating high sensitivity in detecting AMX.

Background: Dental caries is a common infectious disease that leads to the demineralization and structural degradation of the tooth's hard tissues, caused by acid-producing bacteria such as S. mutans through carbohydrate fermentation. One of the essential strategies for caries prevention is using fluoride to inhibit bacterial activity and enhance enamel remineralization. Anchovy Stolephorus commersonnii, widely found in Indonesian waters, were rich in calcium and fluoride, particularly in the form of calcium fluoride (CaF₂), which may offer potential benefits in preventing dental caries. Objective: This study aimed to assess the fluoride concentration in S. commersonnii nanopowder to evaluate its potential as a natural source of fluoride for dental caries prevention. Materials and Methods: This research was a descriptive laboratory-based experimental study. The sample was Stolephorus commersonnii (S. commersonnii). The sample was prepared through drying, acid maceration, and high-energy milling to produce nanoparticle powder. Fluoride content was measured using two methods: a colorimetric method with a spectrophotometer and a portable fluoridemeter based on the SPADNS method. Results: The results showed that the fluoride concentration was 21.05 mg/100 g (21.05 ppm) by spectrophotometry and 20.0 ppm using the SPADNS method. The S. commersonnii nanopowder contained 1,305.80 mg/100 g calcium, 281.60 mg/100 g phosphorus, and 91.5% of particles were in the nano size. Conclusion: S. commersonnii nanopowder contains a considerable amount of fluoride and minerals, suggesting its potential as a natural dietary source of fluoride in supporting dental caries prevention strategies.

Background: Chronic kidney disease (CKD) is a condition in which kidney function gradually declines or is even lost completely. This decline in kidney function can lead to fluid and metabolic waste accumulation in the body, which, if not properly managed, can progress to end-stage kidney failure, requiring renal replacement therapy in the form of dialysis or a kidney transplant. For patients with chronic kidney disease (CKD), the presence of caregivers and family members is the most important source of support. Purpose: To determine the physical and psychological impact of CKD on patients undergoing hemodialysis. Method: This literature review utilized databases such as PubMed, Google Scholar, and Science Direct and included articles published between 2020 and 2024. Inclusion criteria included studies discussing physical activity, quality of life, and psychological aspects in CKD patients undergoing hemodialysis. Studies not available in English or Indonesian, as well as studies not relevant to the topic, were assessed in this review. The search yielded 14 articles, which were selected through keyword selection. Results: Physical activity is an important treatment and prevention measure for chronic kidney disease. The concept of "exercise as medicine" emphasizes that exercise not only helps improve physical function and muscle strength but also provides positive benefits in slowing the progression of chronic diseases. Conclusion: Physical activity such as aerobic exercise, resistance training, and other light exercise can reduce levels of depression and anxiety, improve sleep quality, and enhance perceived quality of life. Suggestion: More longitudinal studies and randomized controlled trials (RCTs) are needed in Indonesia or other developing countries to assess the effectiveness of physical activity-based programs on the psychological aspects of CKD patients. Keywords: Chronic Kidney Disease; Hemodialysis; Psychological; Physical Activity. Pendahuluan: Gagal ginjal kronis adalah suatu kondisi ketika fungsi ginjal secara bertahap menurun atau bahkan hilang sepenuhnya. Turunnya fungsi ginjal dapat menyebabkan penumpukan cairan dan sisa metabolisme dalam tubuh yang apabila tidak ditangani dengan baik akan berkembang menjadi gagal ginjal stadium akhir, membutuhkan terapi pengganti ginjal berupa dialisis atau transplantasi ginjal. Bagi pasien gagal ginjal kronis, kehadiran perawat dan keluarga merupakan sumber dukungan yang paling utama. Tujuan: Untuk mengetahui aktivitas fisik dan psikologis pada pasien chronic kidney disease yang menjalani hemodialisis. Metode: Penelitian literature review menggunakan database dari pubmed, google scholar dan science direct, artikel diterbitkan antara 2020-2024. Kriteria inklusi yang digunakan mencakup studi yang membahas aktivitas fisik, kualitas hidup, dan aspek psikologis pada pasien PGK yang menjalani hemodialisis. Studi yang tidak tersedia dalam bahasa Inggris atau Indonesia, serta yang tidak relevan dengan topik, dikecualikan dari review ini. Pencarian yang diperoleh dari seleksi penilaian dan kata kunci sebanyak 14 artikel. Hasil: Aktivitas fisik merupakan pengobatan dan tindakan pencegahan yang penting untuk penyakit. Konsep “olahraga sebagai obat” menekankan bahwa olahraga tidak hanya membantu meningkatkan fungsi fisik dan kekuatan otot, tetapi juga memberikan manfaat positif untuk memperlambat perkembangan penyakit kronis. Simpulan: Aktivitas fisik seperti latihan aerobik, resistensi, dan latihan ringan lainnya mampu menurunkan tingkat depresi dan kecemasan, meningkatkan kualitas tidur serta persepsi kualitas hidup. Saran: Diperlukan lebih banyak studi longitudinal dan uji coba terkontrol secara acak (RCT) di Indonesia atau negara berkembang lainnya untuk menilai efektivitas program berbasis aktivitas fisik pada aspek psikologis pasien CKD. Kata Kunci: Aktivitas Fisik; Chronic Kidney Disease; Hemodialisis; Psikologis.
