Abstract

This study evaluates the performance and effectiveness of a Wastewater Treatment Plant (WWTP) at a medical device manufacturing facility with a capacity of 6 m3/day. Based on laboratory analysis, the parameters for BOD, COD, TSS, pH, ammonia, and total coliform in the effluent comply with the quality standards stipulated in the Regulation of the Minister of Environment No. 5 of 2014. However, oil and grease parameters showed 0% removal efficiency and failed to meet the standards due to the absence of a specific treatment unit, such as a grease trap. Technical evaluations revealed significant discrepancies in detention times across several primary units. The detention time in the equalisation tank reached 48 hours, far exceeding the design criterion of <2 hours, triggering anaerobic conditions and odour issues. In the aerobic biofilter units, pollutant degradation was suboptimal due to the lack of contact media for microorganism biofilm formation. Furthermore, the sedimentation unit experienced excessive detention time of 12 hours and operational disruptions due to turbulence from existing diffusers, hindering particle settling. This study recommends adding a grease trap, installing biofilter media (such as bioballs or honeycombs), and removing diffusers from the sedimentation tank to optimise treatment efficiency.

Abstract

Hazardous waste is waste generated by a business or activity that has chemical, physical, or biological characteristics that pose a danger to human health and the environment. The medical device manufacturing industry generates hazardous waste, including used lubricating oil, used rags, product rejects, and fluorescent lamp electronic waste. This industry already has a hazardous waste storage facility that temporarily stores hazardous waste, but as the company grows, several new rooms or facilities will be needed to support the production process. Therefore, changes in waste production necessitate the redesign of the hazardous waste storage facility. The data collection method used primary data (field observations and interviews) and secondary data (Rintek Hazardous Waste Management and regulations applicable to hazardous waste management in Indonesia). Based on the findings of gaps and waste volume data, the number of containers was recalculated, and a space requirement analysis was carried out by grouping waste into compatible zones and ensuring physical separation. The selection of containers and packaging materials was adjusted to the waste's physical and chemical properties. The redesigned layout applies a separate block system based on a compatibility matrix so that incompatible waste is not stored side by side, with a safe distance of 60 cm in accordance with Minister of Environment and Forestry Regulation No. 6 of 2021.

Abstract

Palm sugar (Arenga pinnata Merr.) is a natural sweetener with the potential to be developed as an alternative to white sugar due to its distinctive sensory characteristics and its reported lower glycemic index. However, quantitative data on the glycemic index of various forms of palm sugar products remain limited. This study aims to analyze the in vitro glycemic index of various palm sugar products, namely liquid sugar, molded sugar, and granulated palm sugar, and to compare them with white sugar as a reference. Additionally, the study also evaluates the chemical characteristics (moisture content and ash content) and organoleptic properties of each product. The glycemic index determination was performed using an in vitro method based on enzymatic digestion simulation and the calculation of the area under the curve (AUC) of glucose release, with glucose serving as the reference food. The results of the study indicate that all palm sugar products have a low glycemic index, namely 39 for liquid sugar, 37 for molded sugar, and 35 for granulated palm sugar, while white sugar has a moderate glycemic index of 60. The differences in glycemic index values are related to variations in sugar composition, mineral content, and the physical characteristics of each product. Organoleptic testing showed that palm sugar, particularly granulated palm sugar, received good acceptance for its color, aroma, taste, and texture. Overall, the results of this study demonstrate that palm sugar has the potential to serve as a low-glycemic index alternative sweetener, supporting the development of downstream palm sugar products and the diversification of healthier food options.

Abstract

The rising energy demand in Indonesia is driving the development of biodiesel as a sustainable, renewable fuel. Waste cooking oil has the potential as a biodiesel feedstock due to its abundant availability and relatively low cost. Biodiesel is generally produced via transesterification, but conventional heating methods have limitations, such as long reaction times and high energy consumption. Therefore, microwave-based heating is used as an alternative to improve process efficiency through rapid, even heating. This research aims to' optimize biodiesel synthesis from used cooking oil using a microwave-assisted transesterification process with the Response Surface Methodology (RSM) and Analysis of Variance (ANOVA) approaches. The process variables studied include catalyst' concentration (1', 2, 3, 4, and' 5%w/w) and' reaction time (2, 4, 6, 8, and 10 minutes), with biodiesel yield as the main response. A mathematical model was developed using an appropriate experimental design and statistically validated using ANOVA to assess the model's significance and the effects of interactions between variables. The research results showed the highest biodiesel yield at 4% catalyst with a reaction time of 6 minutes. The RSM method, validated by ANOVA, was effective in determining optimum operating conditions and increasing biodiesel yield. This approach has the potential to be applied as a highly effective and sustainable method for biodiesel production from used cooking oil.

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.
