Abstract

Lead as the most commonly used material for radiation shielding but possessing toxic properties. This research aims to identify alternative, lead-free, and non-toxic materials for gamma radiation shielding through Monte Carlo simulations. Bismuth Oxide (Bi2O3), Barium Oxide (BaO), Tungsten Trioxide (WO3), Tungsten Dioxide (WO2), and Molybdenum Trioxide (MoO3) were selected as potential substitutes for lead. Pure lead (Pb) and Lead Oxide (PbO) were used for comparison. The simulation were performed using Particle Heavy Ion Tracking System (PHITS) software, with a gamma energy of 662 keV. The result of the simulation shows that the linear attenuation coefficient values for Pb and PbO were 0.902 mm-1 and 0.74 mm-1, respectively. Meanwhile, the simulation results of those simulated materials that are closest to Pb and PbO are Bi2O3 and WO2 with an attenuation coefficient of 0.71 mm-1. This simulation shows that for non-lead materials, BiO2 and WO2 have potential as alternative of non-lead radiation shielding.

Abstract

Peatlands have a crucial role in the global regulation of climate, the sequestration of carbon, and the conservation of biodiversity. Daily human activities and climate change have caused various environmental changes and ecological relationships for peatlands. An important thing to worry about is the decline in water quality, which harms the health and welfare of local communities that depend on clean water sources and drinking water from natural water. Additionally, the escalating demand for clean water necessitates substantial efforts in processing peatland water resources. The degradation in water quality harms the ecology and health of humans who use it for daily needs. Single Flow Ultrafiltration technology has emerged as a promising water treatment method, showing great potential in treating peat water while maintaining the ecological balance of peatlands. This research aims to evaluate the effectiveness of a combined treatment process consisting of filtration, absorption, microfiltration, and single-flow ultrafiltration. The application of this technology is carried out in the South Kalimantan region, with water processing stages, namely raw water filtration, semi-finished raw water filtration, ultrafiltration, and an ultraviolet irradiation process at the final stage so that the water is ready for consumption. Using both techniques, empirical methodologies were utilized to analyze the results of water quality and production capacity. This study proposes single-flow ultrafiltration to treat peat water for daily use. This research shows that the single-stream ultrafiltration treatment method for peat water gives a better water quality result than ordinary ultrafiltration treatment. This is indicated by the percentage difference in decreasing TDS values by 149%, turbidity by 200%, and color by 500%, increasing pH by 14.9%, decreasing nitrite by 135%

Abstract

The Mura'atul Lughat Islamic boarding school, located in the Sekumpul sub-district, Martapura District, Banjar Regency, requires clean water to ensure the survival of its residents. Bore well water and river water in this area are not suitable for consumption. However, it is not uncommon for Islamic boarding school residents to consume this water. This situation prompted the joint Community Service team from Lambung Mangkurat University and Kalimantan Islamic University Muhammad Arsyad Al Banjari to identify and implement this activity as a way to contribute science and technology to the Mura'atul Lughat Martapura Islamic boarding school. This community service activity enables the Islamic boarding school to utilize a water filtration membrane device, rendering the drilled well water fit for human consumption. Furthermore, the training activities offered can enhance the knowledge and skills of the Islamic boarding school community. We can eliminate the current costs of purchasing gallon drinking water and generate additional revenue for Islamic boarding schools by selling refillable water through membrane filtration devices. Keywords: Garbage, river environment, cleanliness

Abstract

Fluff tea is the residual solid waste generated in the green tea industry and holds the potential for development as a solid fuel in bio-briquettes. This study transformed fluff tea into bio-briquettes utilizing biochar produced through slow pyrolysis. The study aimed to optimize bio-briquettes production from fluff tea using the Response Surface Methodology (RSM) approach through proximate analysis. The cylindrical bio-briquettes were produced using biochar particle sizes of 850, 500, and 150 μm, resin gum adhesive concentrations of 10%, 15%, and 20%, and immersion times in cooking oil of 0, 3, and 6 minutes. The results showed that the overall response by the p-value was <0.05, and the lack of fit was insignificant (p-value >0.05). The findings indicated that the calorific value of tea fluff rose from 4,482.56 cal/g to 6,374.98 cal/g after conversion to biochar. The optimum conditions for producing tea fluff bio-briquettes were a particle size of 850 μm, adhesive concentration of 11%, and immersion time of 5 minutes. The bio-briquettes exhibited a moisture content of 3.53%, ash content of 5.65%, volatile matter of 14.75%, fixed carbon of 76.14%, calorific value of 7,796.37 cal/g, combustion rate of 0.11 g/min, density of 1.22 g/cm3, and compressive strength of 35.57 N/cm2. Most tea fluff briquettes' properties had met Indonesia's briquettes standard. The production of bio-briquettes from tea fluff waste is a viable alternative fuel for both industrial and domestic applications.

Abstract

Precision in radiation dose delivery is critical in cervical cancer treatment to ensure effective tumor control while minimizing damage to surrounding healthy tissues. Given the increasing adoption of advanced radiation therapies, comparative studies on dose distribution between different modalities are essential for evidence-based treatment planning. This study aims to compare the dose absorption in cervical cancer treatment using proton and gamma radiation through Monte Carlo simulation modeling. A Monte Carlo simulation was conducted using the Particle and Heavy Ion Transport code System (PHITS). Proton beams with an energy of 120 MeV and gamma rays at 30 MeV were applied from the anteroposterior (AP) direction using a pencil beam configuration (1 mm × 1 mm). Anatomical data were obtained from Digital Imaging and Communications in Medicine (DICOM) files sourced from RSUD Ulin Banjarmasin. Dose distribution was assessed in the target region and organs at risk (OAR). The results showed that proton therapy delivered a higher absorbed dose to the cervical target area (34.5 ± 1.5 MeV) than gamma radiation (16.7 ± 2.3 MeV). While both conformed to ICRU Report No. 78, gamma radiation resulted in higher doses to nearby organs such as the rectum and bladder, indicating a greater risk of radiation-induced side effects. Proton therapy offers more targeted dose delivery with reduced exposure to surrounding organs, making it a potentially safer and more effective modality for cervical cancer treatment. These findings underscore the importance of modality selection in optimizing therapeutic outcomes and minimizing complications in radiotherapy.

Abstract

Pemanfaatan limbah biomassa kelapa sawit sebagai bahan baku material fungsional berpotensi memberikan solusi berkelanjutan dalam pengelolaan limbah dan pengembangan teknologi sensor. Penelitian ini bertujuan untuk mengkarakterisasi gugus fungsi permukaan dari arang cangkang, tandan kosong, dan campuran keduanya melalui spektroskopi FTIR, guna mengevaluasi kelayakannya sebagai prekursor dalam sintesis komposit reduced Graphene Oxide (rGO)–Fe₃O₄ untuk aplikasi sensor magnetik geofisika. Sampel arang diperoleh melalui pirolisis pada suhu 400 °C selama 1 jam, kemudian dianalisis pada rentang spektrum 400–4000 cm⁻¹. Hasil menunjukkan bahwa arang campuran menampilkan struktur aromatik C=C paling dominan (%T 80% pada 1585 cm⁻¹), kandungan gugus karbonil (C=O) yang rendah (%T 90,7%), dan gugus eter/alkohol (C–O) yang cukup sebagai situs ikatan Fe₃O₄. Interaksi termokimia antara lignin dalam cangkang dan selulosa dalam tandan menghasilkan atmosfer reduktif internal yang meningkatkan kualitas rGO tanpa memerlukan perlakuan kimia agresif. Dengan kombinasi tersebut, arang campuran menawarkan kestabilan struktural, konduktivitas, dan kompatibilitas kimiawi yang superior dibandingkan bahan tunggal. Hasil ini menunjukkan bahwa limbah arang kelapa sawit, khususnya dalam bentuk campuran, sangat potensial sebagai prekursor lokal untuk pengembangan sensor magnetik berbasis nanokomposit yang ramah lingkungan dan efisien.
