Abstract

Grade X students of SMA Negeri 2 Bontang experienced problems of low biology learning outcomes and lack of collaboration skills due to conventional teacher-centered learning. This study aimed to determine the effect of implementing the CTL (Contextual Teaching and Learning) model on students' collaboration skills and learning outcomes. The CTL model emphasizes active student involvement in the learning process, connecting material with real-life contexts, and encouraging collaboration and group discussion. This study used a quantitative approach with a quasi-experimental method and a non-equivalent control group design. Sampling was carried out by purposive sampling, with class X5 as the experimental class implementing the CTL model and class X6 as the control class using conventional methods. Data analysis was carried out using the N-Gain test and the Independent Sample t Test. The results showed that the experimental class had an N-Gain value of 0.72 (high category) while the control class had 0.59 (moderate category). The t test showed a significance value of 0.000 <0.05 for collaboration skills and learning outcomes. These results indicate a significant difference between the experimental class and the control class after the CTL model was implemented. Based on these results, it can be concluded that the application of the CTL model has a positive and significant effect on improving the collaboration skills and learning outcomes of class X students of SMA Negeri 2 Bontang in biology subjects.

Abstract

Nile Tilapia (Oreochromis niloticus) is highly sought after by Indonesian consumers and is one of the leading commodities cultivated in freshwater. However, tilapia farming still frequently encounters challenges that lead to a decline in production, one of which is infection by pathogens such as Tilapia Lake Virus (TiLV). TiLV can infect fish in waters with temperatures above 25°C, with mass mortality peaking at 30°C, reaching a 50% death rate. Proper handling and control measures are essential to manage TiLV outbreaks effectively. TiLV detection in fish can be conducted using the Polymerase Chain Reaction (PCR) method. PCR-based virus detection is a diagnostic technique that identifies the presence of viral genetic material with high specificity and accuracy. This study aimed to detect TiLV infection in farmed Nile tilapia. The procedures included sample collection, necropsy, organ fixation, RNA extraction, PCR amplification, electrophoresis, and gel documentation analysis. Based on the PCR results, Nile tilapia samples tested positive for TiLV infection, as indicated by the presence of a 250 bp DNA band in the gel documentation system, aligning with the TiLV positive marker. Among the three fish showing suspected TiLV symptoms, two (66.6%) were confirmed infected.

Abstract

The rapid growth of e-commerce in the pharmaceutical sector requires companies to understand key factors influencing consumer purchasing decisions. This study analyzes the effects of product variety, service quality, and delivery methods on purchasing decisions on PT W Pharmacy’s e-commerce platform, with promotion as a moderating variable. A quantitative approach using SEM-PLS was applied to data from 301 respondents. The results show that product variety has a positive and significant effect (coefficient = 0.207; t = 3.623; p = 0.000), as does service quality (coefficient = 0.157; t = 2.150; p = 0.032). Delivery methods show the strongest positive and significant effect (coefficient = 0.227; t = 4.223; p = 0.000). Promotion also directly has a positive and significant effect on purchasing decisions (coefficient = 0.362; t = 4.853; p = 0.000). As a moderating variable, promotion significantly strengthens the effect of service quality (coefficient = 0.196; t = 2.135; p = 0.033), does not significantly moderate product variety (coefficient = -0.090; t = 1.373; p = 0.170), and has a significant negative moderating effect on delivery methods (coefficient = -0.120; t = 2.019; p = 0.044). These findings emphasize the strategic role of delivery, service quality, and targeted promotion in enhancing online purchasing decisions
