Abstract

Lombok has become one of the leading tourist destinations, especially with the development of the Mandalika Special Economic Zone. One of the cultural products that has the potential to be offered to tourists is Lombok traditional weaving. The study aims to analyze the effect of the pH of the dye solution on the characteristics of the dyed fabric. The research method uses a mechanical thermal method to obtain anthocyanin powder extraction, standard staining methods namely mordan, staining, and fixation, as well as characterization using tensilons, Color Analyzer software, Hooloovoo, and Encycolorpedi website. The extraction of anthocyanin compounds from teak leaves (Tectona grandis) was successfully carried out by mechanical thermal method. Color analysis and identified color changes are significantly affected by differences in solution pH. The higher the pH used, the darker the color will be produced and the higher the level of color fading in the fabric. The smallest  E value is at pH 6 =5.364 and the largest  E value is at pH 14 = 17.145. However, an increase in pH tends to increase the tensile strength of the fabric. However, the optimum tensile strength condition was obtained in a solution of pH 12, which was 17.414 MPa, while at pH 13 and pH 14, the tensile strength of the fabric decreased to 16.071 MPa. Based on the analysis of the influence of pH of dye solution on fabric tensile strength, it was identified that a 6th-order polynomial model (determination coefficient R2 = 0.9479) was identified as accurate enough to model the influence of pH on fabric tensile strength. Therefore, this finding has potential in the textile industry, especially in increasing the economic value of Lombok weaving.

Abstract

This study has succeeded in synthesizing and characterizing TiO2/CaTiO3 perovskite composites using calcium carbonate (CaCO3) from shellfish waste (Pinctada maxima). Synthesis was carried out through the coprecipitation method with variations in the molar ratio of CaCO3:TiO2 and calcination temperatures (700oC, 800oC, and 900oC). Characterization was carried out using FTIR, DTA-TG, XRD, SEM-EDS, BET and UV-Vis. The results of the analysis showed that the calcination temperature affected the powder color, crystal structure, thermal properties and particle size. The DTA-TG analysis shows that increasing the calcination temperature up to 900oC significantly reduces mass loss to 51.88%, with minimal thermal events, indicating the formation of a thermally stable and well-crystallized TiO2/CaTiO3 structure. At a temperature of 900oC, a more perfect CaTiO3 was formed with the whitest powder color, the anatase and brookite phases of TiO2 were still detected, while the calcite phase was still found at a temperature of 700oC. The morphology of the samples showed agglomeration with increasingly uniform particle sizes at higher calcination temperatures. Complementary BET analysis confirms that the composite possesses a mesoporous structure with a specific surface area of 11.42 m2/g and a pore size distribution of 3-5 nm, making it suitable for adsorption and photocatalytic applications. UV-Vis analysis showed an increase in the band gap value along with the increase in the TiO2 ratio. This is also confirmed by the presence of Urbach energy which tends to increase with increasing TiO2 ratio.

Abstract

Blood clam shells are inorganic materials rich in  content obtained from heating  at high temperatures, so they can be used as adsorbent. The purpose of this study is to determine the effect of calcination temperature of blood clam shell adsorbents, used to test the quality of used cooking oil (wosting oil). In this study, three calcination temperature variations were used, namely 800 ℃, 900 ℃ and 1000 ℃ for 2 hours each. Then the quality of adsorbent was tested by knowing oxide element with SEM. The adsorption process was carried out using the contact method by immersing the adsorbent in wosting oil for one hour. Wosting oil that has been adsorbed is then tested for quality, namely: free fatty acid content, peroxide number, water content, viscosity, density, physical properties (odor and color). The results obtained are: The best quality of  adsorbent was obtained at a calcination temperature of 1000 ℃ which was analyzed through three parameters namely,  content, density value and surface area. The best quality of wosting oil is obtained in used cooking oil with 3 times heating with calcined adsorbent at 1000 ℃ which is analyzed based on several parameters as previously explained.

Abstract

Saturasi oksigen dalam darah (SpO₂) adalah indikator vital yang menunjukkan efisiensi sistem pernapasan dalam mendistribusikan oksigen ke seluruh tubuh. Pemantauan SpO₂ sangat penting dalam deteksi dini gangguan pernapasan seperti penyakit paru obstruktif kronis (PPOK), asma, dan hipoksia. Penelitian ini bertujuan untuk mengembangkan sistem pemantauan SpO₂ berbasis sensor MAX30102 yang dikendalikan oleh mikrokontroler Arduino Uno. Kalibrasi sensor dilakukan menggunakan alat pulse oximeter medis standar untuk memastikan akurasi pembacaan. Pengujian dilakukan dalam kondisi lingkungan terkendali dengan suhu 20°C hingga 27°C. Hasil kalibrasi menunjukkan bahwa sensor MAX30102 memiliki tingkat akurasi tinggi dengan deviasi rata-rata kurang dari 2% dibandingkan alat medis referensi. Pengujian terhadap beberapa subjek menunjukkan bahwa sistem mampu mendeteksi kadar SpO₂ dalam rentang normal (95%-100%) maupun rendah (85%-90%), dengan hasil yang stabil dan konsisten. Dengan hasil yang telah diperoleh, sistem pemantauan kadar oksigen dalam darah berbasis sensor MAX30102 menunjukkan potensi besar dalam mendukung pemantauan kesehatan secara efisien, akurat, dan real-time. Namun, beberapa faktor eksternal seperti pergerakan pengguna, pencahayaan lingkungan, dan suhu tubuh dapat memengaruhi hasil pengukuran. Optimalisasi lebih lanjut diperlukan untuk meningkatkan ketahanan terhadap faktor eksternal dalam berbagai kondisi. Dengan pengembangan yang berkelanjutan, teknologi ini diharapkan dapat berkontribusi dalam meningkatkan kualitas layanan kesehatan dan memberikan manfaat luas bagi masyarakat.

Abstract

Biomaterial implants are one of the alternatives to replace damaged organs in the body system temporarily (scaffolding) or permanently. Bone biomaterial implants can be obtained through the manufacture of HA/Cs/Coll (HA/Cs/Coll) biocompositeses with the addition of Hydroxypropyl Methylcellulose (HPMC) matrix. The objective is to evaluate how variations in material composition and lyophilization time affect the physical properties of the biocomposites, including density, compressive strength, Young’s modulus, and surface morphology. The manufacture of  biocomposites uses the mechanical thermal method for mixing materials and the freeze drying method for the biocomposites drying process. Composition ratios of HA:Cs/Coll were varied at 3:7, 5:5, and 7:3, while lyophilization durations were set at 24, 48, and 72 hours. Characterizations were performed through density measurements, mechanical testing using a Tensilon machine, and surface morphology analysis using a digital microscope. The results showed that the comparison of biocomposites with a ratio of 7:3 had the highest density of 0.150 gr/cm³, compressive strength of 0.046 MPa, and young modulus of 0.3 MPa. Meanwhile, the biocomposites that was lyophilized for 48 hours showed the best balance between a density of 0.145 gr/cm³, a compressive strength of 0.08 MPa, and a young modulus of 0.17 MPa. Morphological analysis revealed improved porosity and surface uniformity with longer freeze-drying times. Based on this, the resulting HA/Cs/Coll biocompositese has potential as an implant material but further research is needed to improve its mechanical properties by increasing the concentration of the binder, namely HPMC.

Abstract

Biocompatible, mechanically stable, and easy-to-use injectable biomaterials are often needed for bone defects caused by trauma, disease, or surgery. This study aims to investigate the effect of polyvinyl alcohol (PVA) concentration on the microscopic and macroscopic characteristics of injectable bone substitute (IBS) formulations composed of Hydroxyapatite (HAp), chitosan, and PVA. The biopolymer chitosan was extracted from pearl oyster shell waste (Pinctada maxima), and HAp was synthesized via precipitation. The formulations were prepared with varied PVA concentrations (5%, 10%, and 15%) and evaluated for their structural, physicochemical, and functional properties. Fourier-transform infrared (FTIR) spectroscopy was employed to determine the presence of functional groups and molecular interactions. Results showed that increasing PVA content enhanced the intensity and sharpness of phosphate () bands, with Sample C (15% PVA) exhibiting the strongest interaction, indicated by a peak shift to 1047.32 cm⁻¹. Organoleptic observations revealed stable color across all samples, with increasing viscosity and paste-like consistency observed in higher PVA concentrations. Sample C had the highest viscosity (82.2 dPa·s) and the lowest injectability (92.43%), while Sample A exhibited the highest injectability (98.33%) and the lowest viscosity (2.79 dPa·s). Sample B (10% PVA) showed balanced characteristics with a viscosity of 38.93 dPa·s and injectability of 97.26%, aligning closely with ideal ranges for injectable biomaterials. Density measurements indicated that all samples approximated or exceeded the minimum density of healthy bone, with Sample C reaching 1.18 g/cm³. pH monitoring over 21 days revealed a consistent value of ~6, suggesting good chemical stability. These results demonstrate that the 15% PVA formulation achieves an optimal compromise between physicochemical properties and clinical applicability. This composite's injectability enables precise defect filling and promotes new bone formation, making it a superior and promising alternative as an injectable bone graft material in patients.
