Dental and oral health problems are one of the problems that need attention. The oral cavity is colonized by various microflora and some bacteria, so it is necessary to develop additional oral cleaning methods besides brushing teeth. Mouthwash with natural ingredients, such as a combination of chitosan and Eucalyptus grandis, is the right choice. Chitosan is a type of water-soluble chitosan characterized using FT-IR. Meanwhile, Eucalyptus grandis was isolated using the Stahl method to obtain its essential oil. Mouthwash was evaluated through organoleptic testing, pH, viscosity, and antimicrobial testing. The most optimal formula is formula III, with an inhibition zone diameter of 11.9 ± 1.5 mm for Streptococcus mutans bacteria, 12.8 ± 0.9 mm for Staphylococcus aureus, and 12.2 ± 0.15 mm for Candida albicans.

The high use of methamphetamine (MA) has resulted in many cases of overdose leading to death, where bodies are generally found after several days which complicates the investigation so that a forensic entomotoxicological analysis using insects is carried out. The use of necrophagous insects was chosen because necrophagous insects such as maggots were at the crime scene. Maggot was then analyzed using Gas Chromatography-Mass Spectrometry (GCMS) with several stages. The preliminary test was carried out using the marquis reagent which changed the color of the sample to orange if positive for methamphetamine, then continued with TLC (Thin Layer Chromatography) analysis and obtained the Rf value close to the comparative Rf value, which means that maggot positively contains methamphetamine. Maggot was extracted by maceration and sonication methods using methanol:chloroform 1:3 solvent. Finally, a confirmatory test was carried out using a GCMS and it was found that methamphetamine had a retention time of 3.554 minutes and a peak of 58.1. The results are matched with NIST (National Institute of Standards and Technology) library data. It can be concluded that the use of maggot in analyzing methamphetamine using GCMS can be realized properly

Phyllanthus emblica L. (Malacca fruit) is a tropical plant traditionally used for its medicinal properties. This study aimed to identify the secondary metabolite content through phytochemical screening and to evaluate the antibacterial activity of n-hexane, ethyl acetate, and ethanol extracts of Malacca fruit against Escherichia coli and Staphylococcus aureus. The simplicia was extracted using graded maceration. Phytochemical screening revealed the presence of flavonoids, terpenoids, steroids, saponins, and tannins. Antibacterial testing was performed using the agar well diffusion method at concentrations of 3.125–100 mg/mL. Results showed that all three extracts exhibited antibacterial activity against both bacteria. The ethanol extract demonstrated the highest inhibition, with zones of 23.78 mm and 21.63 mm against E. coli and S. aureus at 100 mg/mL, respectively. Inhibition zones increased with increasing extract concentration. The ethanol extract exhibited superior antibacterial activity compared to ethyl acetate and n-hexane extracts, likely due to its ability to extract a broader range of polar bioactive compounds.

Heavy metals are often found in river water polluted by industrial processes. To separate heavy metals from river water, blood clam shells (Anadara granosa) are used as adsorbents. This study aims to analyze the determination of Belawan river water pollution based on the Aquatic Insect Diversity Index and analyze the content of heavy metal (Ni) in waste by utilizing blood clam shell waste as an adsorbent. The method used is solid phase extraction. Based on the diversity index data, the condition of the Belawan River waters in the Control area is not polluted (H' 2.18), Settlement Area 1 is lightly polluted (H' 1.94), Settlement Area 2 is lightly polluted (H' 1.70), Industrial Area 1 is moderately polluted (H' 1.47), and Industrial Area 2 is lightly polluted (H' 1.7). The percentage of heavy metal (Ni) absorption in Residential Area 1, Residential Area 2, Industrial Area 1, and Industrial Area 2 were respectively 28.57%, 33.33%, 31.11%, and 34.38%. This shows that blood cockles (Anadara granosa) are able to absorb Ni metal up to 34.38%. Ni levels < 0.05 mg/L so it can still be used (PP No. 22 of 2021).

Conventional synthesis of titanium dioxide (TiO₂) nanoparticles often involves the use of toxic chemicals, high costs, and extreme operating conditions. This research aims to develop a cost-effective and environmentally friendly green synthesis method for TiO₂ by utilizing oil palm leaf (Elaeis guineensis Jacq.) extract as a reducing and stabilizing agent. Subsequently, doping with barium (Ba) was carried out to enhance the photocatalytic, optical, and electrical properties of the resulting TiO₂. Phytochemical analysis revealed that oil palm leaf extract contains alkaloids, flavonoids, terpenoids, saponins, and tannins, which play a role in the reduction and stabilization processes of TiO₂ nanoparticles. Characterization using Fourier Transform Infrared Spectroscopy (FTIR) identified Ti-O bonds in pure TiO₂ at a wavenumber of 588 cm⁻¹, and a shift in absorption peaks in the range of 548-595 cm⁻¹ in Ba-doped TiO₂ indicated the formation of the barium titanate phase. X-ray Diffraction (XRD) analysis showed that Ba doping increased the crystallite size of TiO₂ from 1.17 nm to 1.65 nm, which may have implications for photocatalytic applications.

Kefir is a fermented milk that contains probiotic bacteria. It is made by adding kefir grain starter as a source of lactic acid bacteria. The combination of goat milk and almond milk, along with the addition of pineapple core extract, is an effort to enhance the nutritional value of probiotic kefir milk. The aim of this study is to determine the quality characteristics of the combined kefir made from almond milk and goat milk with varying milk ratios (30:70, 40:60, and 50:50%) and the effect of pineapple core extract on the combined kefir. The combination is expected to produce kefir with unique characetristics due to the nutritional differences between animal-based and plant-based milk. Quality characteristics include pH testing measured using a pH meter, viscosity testing using a Brookfield viscometer, titratable acidity (total acid) using an alkalimetric titration method, and protein content tested using the Kjeldahl method. The results obtained show that the combined kefir made from goat milk and almond milk with the addition of pineapple core extract affects the pH, viscosity, titratable acidity, and protein content. The optimal variation was obtained at a 40:60% ratio, with a pH of 3.7650 ± 0.0849, viscosity of 0.7410 ± 0.0283, titratable acidity (%) of 1.2043 ± 0.0636, and protein content of 1.3509% ± 0.0304.

MDMA is known as a narcotic and stimulant is a drug that is often abused, both in pill and powder form. Therefore, it is important to have an accurate and sensitive analysis method to detect the presence of MDMA especially in urine samples of drug users. In this work, optimization of the GC-MS method was carried out to obtain the best separation conditions and the highest sensitivity using the GCMS instrument. This study aims to develop a validation method for the analysis of 3,4-methylenedioxymethamphetamine (MDMA) using the Gas Chromatography-Mass Spectrometry (GCMS) technique. The results of the analysis showed that the accuracy, precision, linearity, limit of detection, limit of quantification and selectivity were respectively: 97.53%, 3.66%, R² ≥ 0.99, LOD 0.7 ppm, LOQ 2.35 ppm, and Rs 19.83. The results of the study showed that this method has good accuracy with acceptable precision values and low enough LOD and LOQ to detect MDMA at appropriate concentrations. Thus, this validated GC-MS method can be effectively applied for the analysis of MDMA in various urine sample matrices, especially in the development of the field of analytical chemistry.
