Abstract

Abstract: Use of antibiotics and chemicals substances were done to prevent bacterial attacks especially byVibrio sp, which if used excessively will cause bacterial resistance. Another problem that arises is the risk ofdamage to the surrounding environment of fish farming and human health, therefore the use of thesesubstances must be effective and efficient. The research aims to determine the antimicrobial inhibition duringthe handling of cage-cultured fish diseases and to determine the level of resistance to antimicrobialsubstances (Antimicrobial Resistance/AMR) to obtain recommendations for the sustainability ofantimicrobial use. Disk diffusion test method with antibiotics Oxytetracycline, Enrofloxacin, andTetracycline in paper disc form was used in the inhibition test. Bacterial identification used biochemical testswith bacterial culture media (TCBS) also biochemical tests using the API 20E kit. The results show that theinhibitory power of using the three types of antibiotics is able to provide sensitive and intermediate responsesto Vibrio sp bacteria. Sensitivity inhibition in white snapper, trevally, grouper, and humpback grouper withoxytetracycline antibiotics all at 60%, enrofloxacin antibiotics respectively 80%, 100%, 100%, and 80%;and tetracycline antibiotics respectively 60%, 100%, 60%, and 80%. Intermediate inhibition with the samegroup of fishes with oxytetracycline antibiotics all at 40%, enrofloxacin antibiotic in all fish 0%, except inhumpback grouper 20% and tetracycline antibiotics respectively 40%, 0%, 40%, and 20%. Thus, it can beconcluded that the use of oxytetracycline, enrofloxacin, and tetracycline antibiotics can still be recommendedfor the management of diseases in aquaculture. For common bacteria, two types of bacteria Vibrioparahaemolyticus and Vibrio alginolyticus have been found.Keywords: Resistance, Vibrio spp, antibiotics, fish farming

Abstract

This study aims to analyze the influence of self-regulated learning and learning styles on the mathematical problem-solving abilities of students at SMA Negeri Ilugua, Mamberamo Tengah Regency, Papua Pegunungan Province. A quantitative approach with a survey design was used. The population consisted of all students at SMA Negeri Ilugua, and the sample included 102 students selected through simple random sampling. Data were collected using an essay-based mathematics problem-solving test and questionnaires to measure self-regulated learning and learning styles. The findings show that: (1) self-regulated learning has a significant effect on students' mathematical problem-solving ability, contributing 48.5% to the variance; (2) learning styles significantly influence problem-solving ability, with kinesthetic learners achieving the highest scores, followed by auditory learners, while visual learners had the lowest; (3) simultaneously, self-regulated learning and learning styles have a significant combined effect, contributing 59.9% to the improvement of problem-solving abilities. These results emphasize the importance of promoting self-regulated learning and tailoring instructional strategies to students' learning styles to enhance mathematical problem-solving skills, particularly in remote regions such as Papua. The study suggests that adaptive learning approaches and stronger interventions to develop learner autonomy are essential for improving educational outcomes.

Abstract

Modules are very important developed in chemistry learning. Modules as teaching materials are very minimal so that they become obstacles in chemistry learning, especially acid-base solution materials. Therefore, this study aims to develop and validate the feasibility of chemical modules on acid-base solution materials through a problem-based learning approach, as well as to examine the responses of students and teachers to the developed products. The method in this study uses research and development (R&D) methods and ADDIE is a development model applied as a methodology. The sample in this study was 25 students. The sampling technique is saturated samples. The module is validated by the material and media validators then validated by the teacher and asked for feedback from students. The data was processed using SPPS acid-base solution as the subject of this study. The module was developed because it is very feasible to be applied in chemistry learning to acid-base solution materials, based on the results of data analysis. The material validator gave an average score of 92% (very decent), the media validator 95% (very decent), the teacher's response to 96% (very good) and the students' response to the developed module was 98% (very good) and the average was 94% (very decent).

Abstract

This study aims to analyze the influence of the Project-Based Learning (PjBL) model on the learning outcomes of high school students in Pascal's Law material. The background of this research is the low level of students' understanding of Pascal's Law, which is often taught theoretically, so it is less contextual and can be applied. This study uses a quantitative approach with quasi-experimental methods and Pretest-Posttest Design of Control Groups. The research subjects were 11th grade students of SMA Negeri 1 Sei Bamban for the 2024/2025 academic year, with a total sample of 60 students, consisting of 30 students in the experimental class and 30 students in the control class, selected using purposive sampling. The research instrument consisted of a multiple-choice learning outcome test with 20 validated items and an observation sheet of student activities. The results showed that the average pretest scores of the two classes were relatively equivalent (experimental = 45.33; control = 45.17) with a significance value of 0.960 (>0.05), indicating no significant difference in initial ability. After treatment, the average post-experimental class score increased to 78.67, while the control class only reached 66.33. The t-test reveals a significant difference between the two classes (Sig. <0.05). Student activity in the experimental class was also recorded high, with an average of 79.97% in the active category. It can be concluded that the application of the Project-Based Learning model has a significant influence on improving student learning outcomes in Pascal's Law compared to conventional learning. These findings reinforce previous literature on the effectiveness of PjBL as an innovative learning strategy that is able to connect abstract concepts with students' real-life experiences.
