Abstract

Hypothyroidism is characterized by inadequate production of thyroid hormones, chiefly thyroxine (T4) and triiodothyronine (T3). Thyroid peroxidase (TPO), is an enzyme and crucial for producing thyroid hormones, and also serves as a primary autoantigen in autoimmune thyroid conditions, such as Hashimoto's thyroiditis and Graves' disease. The existence of anti-thyroid peroxidase antibodies (anti-TPO) indicates an autoimmune response in which the immune system TPO which is normally recognized as part of the body (self), begins to be identified by the immune system as a something foreign (non-self). This study aimed to characterize, measure TPO activity, and evaluate the immunogenicity of TPO protein derived from patient serum and its ability to induce TPO antibody production in New Zealand White Rabbits. TPO protein isolation was achieved through SDS-PAGE and confirmed by western blot technique have molecular weight of 52 kDa. In samples from normal patients, the average TPO enzyme activity was 31.34 U/mL, while in hypothyroid patients, the average activity increased to 49.46 U/mL. TPO polyclonal antibody production in rabbits indicated its immunogenicity, peaking in week eight post-immunization, with an ELISA absorbance of 0.555. Dot blot analysis further confirmed anti-TPO sensitivity at various dilutions, anti-TPO has a high sensitivity at 1:80 dilution still detects TPO in sera patient.

Abstract

Natural sciences—particularly psychology and biology—can be applied to better understand human behavior, cognitive processes, stress responses, and other factors influencing workplace dynamics and employee well-being. Natural science relies on empirical evidence gathered through observation, experimentation, and data analysis. It aims to formulate theories and laws that explain the natural world and predict future outcomes. The emergence of Industry 4.0 has transformed the landscape of Human Resource Management (HRM) by introducing advanced technologies, including artificial intelligence (AI), machine learning, and big data analytics. These innovations have enhanced HRM processes such as recruitment, training, performance evaluation, and employee engagement. Natural sciences play a critical role in understanding the dynamics of these technological advancements, offering insights into human behavior, cognitive processes, and organizational ecosystems. This article explores how principles of natural science, including biology, psychology, and neuroscience, integrate with modern HRM practices in the 4.0 era. Through a qualitative approach, we examine case studies to illustrate the application of natural science in HR strategies, highlighting the advantages and challenges of adopting a scientifically-informed HRM framework.

Abstract

This research aims to evaluate the performance of contract employees using the Weighted Aggregated Sum Product Assessment and Borda methods. The Weighted Aggregated Sum Product Assessment approach uses mathematical calculations, thereby producing precise and accurate results. The Borda technique is useful because it efficiently aggregates diverse rankings of alternatives through voting groups that combine many preferences. The choice of these two methodologies has the ability to produce more efficient solutions to complex problems by guiding or making decisions more quickly in resolving problems. The determining criteria for assessing the performance of contract employees are punctuality or attendance, skills, knowledge, communication, decision making, discipline, adaptation to the work environment, work safety and initiative.  The results of the calculation process from the ranking combination of the weighted aggregate sum product assessment and the borda method were obtained by placing alternative 5 as an employee who is worthy of being a permanent employee and getting the highest score of 0.288. All calculations using this method can be a guide in making decisions at PT SMART Tbk Surabaya, because the accuracy of contract employee performance evaluations has a significant influence on achieving company goals in the permanent employee recruitment process.

Abstract

The level of pond productivity is influenced by the environmental conditions of maintenance caused by the physiochemical and biological quality of pond waters. Biological parameters of waters consist of the abundance of Phytoplankton and Bacteria. The purpose of this study was to determine the correlation between the abundance and types of Phytoplankton and Bacteria in pond water to the productivity level of whiteleg shrimp (Penaeus vannamei) ponds in different DOCs cultivated with an intensive system. The research method used observed maintenance parameters, namely the diversity and abundance of Phytoplankton including Green Algae (GA), Blue Green Algae (BGA), Diatome, and Dinoflagellate groups. Other parameters include Total Bacteria Count (TBC), Total Vibrio Count (TVC) Yellow, and Total Vibrio Count (TVC) Green. These research parameters will be subjected to Multiple Linear Regression analysis on the total harvest, feed conversion value (FCR), and survival rate (SR) of whiteleg shrimp obtained from each pond. The results of the study showed that the abundance of Phytoplankton based on the group from the lowest to the highest value was the Dinoflagellate group of 0 cells/mL with the GA group of 1.52 x 106 cells/mL. Parameters found that were significant to the level of pond productivity were the abundance of TBC and BGA (P <0.05). The conclusion is that the level of pond productivity is influenced by the abundance of Phytoplankton and bacteria based on the diversity of their species.

Abstract

This study analyzes the non-point source (NPS) pollution load and water carrying capacity of the Bolango River in Gorontalo Province, Indonesia. The river is experiencing water quality degradation due to various human activities, particularly in the upstream and midstream regions. Water samples were collected at six locations along the river during five different periods, with key parameters such as pH, Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Nitrate (NO₃), Total Phosphate (TP), and Total Suspended Solids (TSS) measured. A simulation model, Qual2KW Version 5.1, was employed to estimate the river’s carrying capacity and validate the pollutant load. Results show that TSS levels frequently exceed regulatory limits, particularly in downstream segments, with the highest concentration recorded at 645 mg/L. BOD and COD levels remained within acceptable limits, although some points demonstrated high values due to agricultural and domestic waste discharge. The findings suggest that pollution control strategies should focus on managing agricultural runoff, domestic wastewater, and solid waste, particularly in critical segments of the watershed. Immediate intervention is needed to address the TSS exceedances and mitigate further environmental degradation. This study provides important insights for developing sustainable watershed management practices for the Bolango River
