Abstract

Electrodes play a crucial role in impedance measurements using the EIS method. This study undertook a comparative analysis of impedance measurement outcomes using aluminum, iron, stainless steel, copper, and tin electrodes with mineral water and distilled water as the measurement objects. The impedance Bode plots for mineral water and distilled water showed similar trends across all electrodes, while the phase difference trends varied. In this experiment, copper electrodes emerge as the preferred choice due to their consistently low impedance, particularly at higher frequencies, and their stable phase difference patterns. Additionally, copper electrodes showed superior stability up to 25 kHz, while tin electrodes remained stable up to 50 kHz, albeit valid only from a frequency of 100 Hz. The varying impedance and phase difference in mineral water measurements align with the Warburg impedance circuit, due to the presence of more complex capacitive and inductive elements. Furthermore, measurements with distilled water showed a uniform Bode plot pattern of both impedance and phase difference across all electrodes, making the Randles circuit approach the most appropriate choice in this case. Overall, all electrode types exhibited distinct characteristics.

Abstract

LiFePO4-Silicon doped has been widely developed as a battery cathode material. Due to the doping of silicon atoms, this study aims to determine the peak energy (E0), oxidation state and percentage of component composition for Fe K-edge. The experimental sample used are LFP Si-0%, LFP Si-1%, LFP Si-3% and LFP Si-6%. These samples were characterized using XAS (X-ray Absorption Spectroscopy). XANES spectrum showed the peak energy of Pre-edge area is 7113.08 – 7114.49 eV. The oxidation state of Fe atoms were increased and tend to be Fe3+ than Fe2+. Moreover, Linear Combination Fitting (LCF) used to determine the ratio composition FeO/Fe2O3 in experimental samples. The ratio composition indicated Fe atom is multivalent, when the percentage of silicon-doped increases, the ratio of Fe3+ increased.It has been found that the presence of silicon atoms in the LiFePO4 structure has an effect in electronic structure.

Abstract

Stunting dan anemia merupakan masalah kesehatan masyarakat paling umum yang berdampak pada kualitas sumber daya manusia di masa mendatang. Prevalensi stunting di Kecamatan Babulu, Kabupaten Penajam Paser Utara tercatat sebesar 14,64% pada balita, serta kasus anemia yang kerap terjadi pada remaja putri tingkat SMP dan SMA. Sebagai bentuk aksi nyata dalam upaya menghadapi masalah tersebut, dilaksanakan program BARIS (Babulu Atasi Risiko Stunting) yang merupakan salah satu kegiatan Kuliah Kerja Nyata (KKN) melalui intervensi berbasis penyuluhan di enam sekolah menengah dengan fokus meningkatkan pengetahuan siswa terhadap stunting dan anemia. Penyuluhan dilakukan dengan metode ceramah interaktif, diskusi, serta evaluasi pre-test dan post-test untuk melihat bagaimana peningkatan pengetahuan siswa mengenai stunting dan anemia. Partisipan yang ikut serta dalam program ini berjumlah 489 siswa. Terdapat peningkatan rata-rata nilai pengetahuan berdasarkan hasil evaluasi, yaitu dari 73,88 pada tahap pre-test menjadi 80,03 pada tahap post-test, dengan selisih nilai 6,15. Nilai terendah dari total keseluruhan sekolah meningkat dari 22,22 menjadi 33,33, sedangkan nilai tertinggi mencapai 100 pada beberapa sekolah. Berdasarkan analisis N-Gain score, menunjukkan peningkatan berada pada kategori rendah hingga sedang. Hasil ini menunjukkan bahwa intervensi penyuluhan mampu meningkatkan pengetahuan siswa, meskipun peningkatan belum optimal dan masih memerlukan pengembangan dan beberapa evaluasi lebih lanjut. Program ini diharapkan dapat menjadi model pengabdian masyarakat yang dapat dilaksanakan di wilayah lain dalam rangka mendukung upaya preventif dalam menangani kasus stunting dan anemia sejak dini.

Abstract

Thermoluminescent Dosimeter (TLD) is a personal dosimeter to measure radiation exposure which can capture and store radiation energies. It hits them and emits them in the form of light when heated. TLD aims to measure radiation exposure received by radiation workers. The purpose of this study was to determine the effective dose value of lung tissue at the Radiology, Radiotherapy, and Nuclear Medicine Installations in 2018 until 2021 at A.W. Sjahranie Samarinda Hospital. Data processing in this study was carried out using quantitative analysis techniques, i.e., descriptive statistics. This analysis technique used secondary data obtained from the results of recapitulation of absorbed dose values in Radiology, Radiotherapy, and Nuclear Medicine Installations. Data processing was performed by multiplying the equivalent dose values by the lung tissue weight factor. The results of these calculations are visualized in the form of graphs based on the effective lung doses for years and types of installation. Based on this study, in general, the highest to lowest effective dose values for lung tissue are from the Radiotherapy, the Nuclear Medicine, and the Radiology Installations. It matches theoretically in various references.

Abstract

Radiological phantom is a teaching and simulation tool designed to replicate the physical properties and characteristics of human body tissues, primarily for the evaluation of medical imaging. One alternative material for phantom fabrication is the blood cockle shell (Anadara granosa), which contains hydroxyapatite (HA). This study aims to investigate the effect of varying material compositions on the linear attenuation coefficient (μ) of X-rays in bone phantoms, as well as to determine the optimal composition that approximates the reference values of human bone. The research method involved mixing rice bran, resin, and HA powder synthesized from blood cockle shells in varying HA compositions of 20g, 25g, 40g, and 50g. Each phantom was then scanned using  a CT scanner to obtain CT Number values, which represent the linear attenuation coefficient (μ) values. The results showed that the correlation between composition and μ value was not entirely linear, due to the uneven distribution of HA and the presence of voids within the phantom structure. Among the four samples, the phantom with 40 grams of HA (Phantom 3) demonstrated the closest approximation to cortical bone characteristics, with an average CT Number of 1102.15 HU and a μ value of 0.441 cm⁻¹, approximating the attenuation coefficient of human cortical bone. These findings highlight the potential use of waste materials such as blood cockle shells as a main material for bone phantoms that can closely mimic human bone properties.

Abstract

Carbon is one of the abundant elements obtained from organic matter, one of which is found in the fronds of oil palm trees which is found on the Kalimantan Island. This research uses local organic waste in East Kalimantan to be used as activated carbon material, palm frond waste. Activated carbon material is one of the materials that has a high surface area and is widely applied for adsorbent materials. This study aims to analyze and compare the surface area of activated carbon synthesized from palm frond waste using different activating agents. This research also analyzes the nature of the material structure, surface area, pore size and pore volume of activated carbon. The method used is the process of thermal activation and chemical activation to convert carbon into activated carbon with variations of activating agents, phosphoric acid (H3PO4) and sodium hydroxide (NaOH). XRD, BET-SAA and SEM-EDX characterization tests were conducted. The results obtained show that the amorphous structure of activated carbon has been formed and there is an increase in BET surface area due to the activation process. The surface area obtained for the Non-Activated Carbon (C) sample is 15,149 m2/g, Activated Carbon-NaOH (AC-1) is 2,082 m2/g, Activated Carbon-H3PO4 (AC-2) is 307,692 m2/g. This shows that the best sample with the highest surface area is the AC-2 sample which uses the H3PO4 chemical activator solution.
