Abstract

The Central Laboratory of Universitas Andalas is equipped with Shimadzu 9050 Quadrupole Time-of-Flight (QTOF) LC-MS/MS instrument, which has strong potential to support scientific research at international standards. However, the utilization of this instrument remains limited due to the lack of optimized standard methods for both qualitative and quantitative analyses. This study aims to develop an LC-MS/MS analytical method that can be used as a standard method for research services in the laboratory. The research stages included sample preparation of red flower (BM) and white flower (BP) by extraction of sample using methanol pH 3 as the solvent, separation of sample using a rotary evaporator, method optimization including selection of mobile phase composition (isocratic and binary gradient), selection of analysis time (5, 10, and 15 minutes), and optimization of collision energy in the range of 5–40. Quantitative analysis of flower samples was then conducted using the optimized method. The optimisation results showed that a binary gradient mobile-phase method with an analysis time of 15 minutes and a collision energy of 25 could be used as the analytical method. Furthermore, quantitative analysis of both flower samples revealed that cyanidin in the red flower sample was 24.92 ppm, while cyanidin in the white flower sample was 71.69 ppm.

Abstract

Salt waste (bittern) is a byproduct of the salt processing industry that is rich in magnesium, but is often not optimally utilized and is discharged into the environment. This study aims to produce magnesium oxide (MgO) from salt waste through a synthesis and characterization process. The synthesis process begins with the precipitation of magnesium hydroxide (Mg(OH)2) using sodium hydroxide (NaOH), which is then calcined at various temperatures and times to convert it to MgO. The calcination temperature variations used include 300–700°C, and calcination times between 2 and 6 hours. Product characterization was carried out using the XRF method for chemical composition analysis, XRD to determine the crystal structure, and SEM to observe particle morphology. The results showed that calcination temperature and time have a significant effect on MgO formation. The optimal temperature to produce the highest MgO is 500°C, with the best calcination time of 3 hours. Under these conditions, the resulting MgO has a crystal size of approximately 42 nm and a uniform and porous particle morphology. This research proves that salt waste has great potential to be utilized as a raw material for magnesium oxide, which not only reduces environmental pollution but also provides economic added value.

Abstract

This study investigates the syntesys of hydroxyapatite (HAp) from chicken bone waste, which is abundantly available due to high poultry production, using a high-temperature method. The objective of this study was to determine the effect of variations in sintering temperature (300, 400, 500, and 600°C) and sintering time (3, 4, 5, 6, and 7 hours) on the yield and Ca/P ratio of the HAp produced. The prepared chicken bone powder was first calcined at 900°C for 3 hours before sintering. The results showed that the optimal conditions were 600°C for 7 hours, characterized by a change in the sample's colour to white and a yield of 69%. XRF analysis confirmed the formation of HAp with a Ca/P ratio of 1.69. It was concluded that a sintering temperature of 600°C for 7 hours is optimal for producing pure HAp from chicken bone waste.

Abstract

The research was carried out in two stages. First, the electrocoagulation process was performed using aluminium electrodes with electric current settings of 1, 2, 3, 4, and 5 amperes and contact times of 20, 30, 40, 50, and 60 minutes. Second, the ozonation process was conducted with contact time variations of 0, 15, 30, 45, and 60 minutes. The analysed parameters were TSS, COD, and colour, and the data were further evaluated using ANOVA to determine the statistical significance of the treatment factors. The combination of electrocoagulation and ozonation demonstrates significant potential as an alternative method for reducing pollutant load in batik wastewater, particularly by lowering Total Suspended Solids (TSS), Chemical Oxygen Demand (COD), and colour. The electrocoagulation process achieved 98% TSS reduction and 67% COD reduction. Subsequently, ozonation further enhanced treatment efficiency, resulting in an impressive 93% reduction in COD and 37% reduction in colour. These promising results highlight the combined method's capability to support more environmentally friendly wastewater treatment efforts.

Abstract

Information systems play a critical role in enhancing service quality and operational efficiency in healthcare institutions. However, personnel and activity management in many hospitals is still conducted through manual or fragmented processes, leading to data duplication, administrative delays, limited transparency, and difficulties in generating accurate reports. RSKM Regina Eye Center faces similar challenges, particularly in recording daily employee activities, managing leave and overtime submissions, and organizing doctor schedules, which are not yet integrated into a unified system. This study aims to design and develop a web-based Hospital Personnel and Activity Management Information System (SIM-KARS) to address these issues. The system was developed using the Waterfall method for software development and implemented with the Laravel framework, supported by PHP, JavaScript, and MySQL. System evaluation was conducted through black-box testing and a user satisfaction assessment. The results indicate that SIM-KARS improves administrative efficiency, data accuracy, transparency, and ease of access to personnel information. User evaluation results show a satisfaction level of 90%, reflecting positive user acceptance and perceived usefulness. This study contributes a practical, integrated model for digitalising personnel and operational activity management in specialised hospitals to support data-driven decision-making and sustainable healthcare administration.

Abstract

The excessive use of synthetic fertilizers and pesticides in biopharmaceutical crop production has raised increasing concerns regarding environmental sustainability and food safety. This study investigated the potential of liquid organic fertilizer (LOF) derived from herbal medicine waste and rabbit urine as an alternative nutrient source for turmeric (Curcuma longa L.), focusing on plant growth, micronutrient uptake, and curcumin accumulation. A factorial randomized complete block design was implemented using varying concentrations of herbal medicine waste LOF (0–200 mL L?¹) and rabbit urine LOF (0–20 mL L?¹). Rhizome biomass, leaf iron (Fe) and boron (B) concentrations, and rhizome curcumin content were evaluated. The results demonstrated that moderate application rates of herbal medicine waste LOF (100 mL L?¹) combined with rabbit urine LOF (20 mL L?¹) effectively enhanced curcumin content without significantly increasing rhizome biomass. Elevated boron accumulation was observed at higher LOF concentrations. These findings highlight the potential of organic waste-derived LOF to improve turmeric quality while promoting sustainable and environmentally responsible cultivation practices.

Abstract

Coal fly ash is an industrial waste containing aluminium and iron with potential for reuse as coagulant materials. This study aimed to recover aluminium and iron from coal fly ash using Microwave Assisted Extraction (MAE) with hydrochloric acid, and to evaluate their application in textile wastewater treatment. Variations in HCL concentration (1-5 M) and extraction time (30-50 minutes) were examined to determine optimal conditions. The result showed that the highest recovery was achieved at 5 M HCL and 40 minutes, with aluminium and iron recovery of 48.4% and 78%. The extracted aluminium and iron were successfully applied as coagulants in textile wastewater treatment, resulting in significant reductions in color to 30 Pt-Co, turbidity to 26.9 NTU, and TSS to 46 mg/L, while maintaining a stable pH value at 6. All treated wastewater parameters complied with the applicable discharge standards. These finding demonstrate that MAE is an effective and promising approach for recovering aluminum and iron from coal fly ash and production sustainable coagulant for industrial wastewater treatment.
