Abstract

Laboratories function as essential academic support units for knowledge acquisition in the implementation of education, research, and community service; therefore, they require effective management and utilization. To enhance integrated laboratory services and management, the POLAR Application (Mobile-Based Laboratory Service Portal) was developed as an innovative solution. This application aims to improve the quality of integrated laboratory services by digitizing service data. Accessible features include the Integrated Chemical Management System (SIBAKI) and the Digitalization of Laboratory Instruments (DILab) utilizing QR Code technology. The POLAR Application is available for download via the Google Play Store and App Store and currently serves over 1,000 active users across various countries, including Indonesia, the United States, France, India, and Japan. The development process involved several stages: conceptualization and feature analysis, database and application structure design, frontend and backend coding, periodic system testing and debugging, and finally, the User Acceptance Test (UAT). This service improvement provides users with a modern, transparent system that synergizes directly with the community. Feedback results indicate that 100% of respondents are now aware of the available laboratory services. This demonstrates that the optimization process has successfully achieved efficiency, making the retrieval of information regarding laboratory services significantly faster and easier.

Abstract

Chemical laboratory wastewater is classified as hazardous due to the presence of compounds that can pose serious risks to both human health and the surrounding environment. Parameters such as Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), and heavy metal content serve as key indicators of water pollution, reflecting its quality and environmental impact. In this study, treatment of complex chemical laboratory wastewater was carried out through coagulation and flocculation processes using natural coagulants derived from chitosan and Abelmoschus leaf extract. The main objective of this research was to evaluate the effectiveness of these organic coagulants in reducing COD, BOD, and heavy metal concentrations. The experiment consisted of two stages: (1) optimization of treatment parameters using the Jar Test method, and (2) analysis of treated and untreated wastewater for COD, BOD, and heavy metals (Cr, Mn, Cu, Pb, Zn, Ni, and Fe) using Atomic Absorption Spectrophotometry (AAS). The results revealed that the treatment successfully reduced COD from 74,928 mg/L to 65,311 mg/L; Cr from 3.422 mg/L to 2.877 mg/L; Mn from 5.084 mg/L to 4.787 mg/L; Cu from 36.548 mg/L to 9.902 mg/L; Pb from 0.169 mg/L to 0.141 mg/L; Zn from 0.342 mg/L to 0.243 mg/L; Ni from 23.79 mg/L to 17.375 mg/L; and Fe from 13.615 mg/L to 7.697 mg/L. However, the BOD value increased from 383 mg/L to 453.5 mg/L, which is likely due to the introduction of organic matter from the natural coagulants and flocculants used. For improved treatment efficiency, further processes such as filtration or adsorption using activated carbon, zeolite, or bentonite, as well as biological treatment with activated sludge, are recommended..

Abstract

The design of practical activities for testing anti-bacterial sensitivity in microbiology practice, often only reach the verification stage using model recipe guidance. It is suspected that the recipe model laboratory activity design has not been able to construct student knowledge. The aim of this research is to develop a video tutorial for anti-bacterial sensitivity testing using VEE diagrams based on the ANKER procedure. The research method chosen was descriptive research through object scoring and even VEE diagrams, The research object was the design of anti-bacterial testing practice activities. Data sources were obtained from documentation studies, observations and interview surveys. Supervision video tutorials resulting from the design reconstruction of practical activities were tested on respondents and an assessment was carried out using a questionnaire survey to strengthen the research results. Scoring of the design of anti-bacterial sensitivity testing practice activities obtained 12 out of 18 points in the good category. Reconstruction of the practical activity design was carried out because the choice of tools and materials had not been identified. Next, video supervision of antibacterial testing was carried out as a result of the reconstruction of the design of practical activities. The results of the questionnaire showed that 72% of respondents thought that the video was suitable for use without improvement, and the remaining 28% thought that the video tutorial was suitable for use but needed improvement.

Abstract

Preservation using glycerol as cryoprotectant agents is expected to be an alternative in maintaining bacterial viability, so that when they are to be used again, the bacteria can grow. The objective of this study was to determine the effect of glycerol concentrations of 10%, 30%, and 50% in the preservation medium and preservation time on the viability of Pseudomonas aeruginosa FNCC 0063 during storage, as well as to determine the effective glycerol concentration and time. Preservation of Pseudomonas aeruginosa FNCC 0063 in the form of bacterial suspensions and pellets was conducted for 30–150 days at a freezer temperature of –40°C. Viability tests were performed from day 30 to 150 using the Plate Count method with Nutrient Agar medium. Two-way ANOVA test of pellet preservation from cell viability data,  significant value 0.000 < 0.05, meaning that viability or the number of living cells is influenced by time and glycerol concentration. Preservation time and glycerol concentration based on the Tukey test results showed the highest average value on day 60 and a concentration of 50%, which was 9.4 x 10⁵ CFU/ml. Suspension preservation: the two-way ANOVA test results showed that preservation time had an effect, but glycerol concentration did not significantly affect cell viability. Tukey test showed that the preservation results on day 120 were significantly different from those at 30–90 days. As for concentration treatment, there were no significant differences between 10%, 30%, and 50%, but the 50% concentration had relatively stable and high viability compared to 10% and 30%, at 6.7 × 10⁵ CFU/ml.

Abstract

Excessive exposure to X-ray radiation can be harmful to human health; therefore, it is important to regularly monitor its intensity, especially in laboratories equipped with ionizing radiation facilities. This research aims to develop an X-ray radiation monitoring system designed to measure radiation levels in the Material Characterization Unit of the Physics Laboratory at Universitas Negeri Semarang. The research method refers to the prototype model, which consists of several stages: communication, quick planning, quick design modeling, and prototype construction. This monitoring system is essential due to the presence of an X-Ray Diffractometer (XRD) machine, which serves as a source of ionizing radiation.The developed system consists of an X-ray radiation detector integrated with an ESP32 microcontroller that transmits data to a cloud server via a Wi-Fi protocol. The radiation detector used in this monitoring system is a Geiger-Müller counter. The measured radiation data can also be displayed on an OLED 128x64 screen. Data acquisition is recorded online using the Google Sheets Application Programming Interface (API), enabling real-time data logging. Experimental results of radiation measurements inside the XRD unit show a radiation dose of 319.2 µSv at a distance of 30 cm from the tube at an angle of 30°, while environmental radiation measurements indicate a dose of 0.815 µSv. The monitoring system’s measurements were compared with those obtained from a standard survey meter, Ludlum Model 3. The results demonstrate that the developed system is capable of measuring X-ray radiation in real-time and can be effectively used for X-ray radiation monitoring.

Abstract

This work was created with the aim of developing maintenance techniques for equipment, namely the X-Ray Diffractometer (XRD) brand/model D8 Advance Made by Bruker Germany, especially in the Water Flow/Cooling Water unit in the Integrated Laboratory of the Faculty of Mathematics and Natural Sciences, Sebelas Maret State University, Surakarta, which has not been available so far. The X-Ray Diffractometer (XRD) tool is currently widely used by students and researchers in understanding and studying the crystal structure of a material. To prevent water flow problems, it is very important to maintain and check the water cooling system regularly to ensure continued peak performance. As part of the filter cooling system in the Water Flow/Cooling Water chiller, it has a role in filtering particles that enter the hose that flows through the X-Ray tube to prevent overheating. The water flow sensor monitors the water flow in the X-Ray Diffractometer (XRD) cooling system, playing an important role in the redundant safety system of the XRD unit and supporting the accuracy and reliability of consistent XRD data. The XRD system is programmed to alert the operator and shut down the X-ray generator if the water flow rate drops below a safe threshold—below approximately 3.6 liters per minute (some machines have a two-stage shutdown process/some go into standby mode). Over time, the filter becomes contaminated with debris, which restricts the water flow to the X-ray Tube, resulting in inaccurate readings from the water flow sensor, which can lead to overheating and potential damage to the X-ray tube. The X-ray Diffractometer (XRD) cannot operate without the support of the Water Flow/Cooling Water system unit on the X-ray tube detector and X-ray generator. Therefore, a regular maintenance system is required by replacing several filters and replacing the water in the Flow/Cooling Water to ensure the equipment operates properly and the X-ray Generator has an optimal.
