Abstract

This study aimed to determine the density of Hydrilla verticillata in Lake Talaga and to evaluate its potential as a bioindicator of changes in water quality caused by domestic pollution. The study was conducted at three stations, where physicochemical parameters were measured, including temperature, pH, light intensity, turbidity, dissolved oxygen, and the heavy metals Pb, Fe, and Cu. The results showed that water temperature ranged from 26 to 28°C and dissolved oxygen from 8.04 to 8.49 mg/L, indicating conditions that still support aquatic life. Heavy metal concentrations were below the established water quality standards. However, the pH was categorized as highly alkaline, and the highest turbidity was recorded at the station located near residential areas, suggesting environmental pressure associated with domestic activities. The density of Hydrilla verticillata varied among stations, reaching 607,333.3 ind/ha at Station II (high category), 180,000 ind/ha at Station I (moderate category), and 6,066 ind/ha at Station III (low category). The high density observed in the residential area indicates nutrient enrichment that may stimulate excessive growth of aquatic vegetation. This condition suggests symptoms of eutrophication and indicates that Lake Talaga is experiencing localized light to moderate pollution. Therefore, the density of Hydrilla verticillata has strong potential to be used as a bioindicator for assessing changes in water quality.

Abstract

This study aimed to examine the effect of providing lecture recordings on students’ self-regulated learning (SRL) in online learning contexts characterized by unstable internet connectivity and limited access to course materials. A quasi-experimental pretest–posttest design was employed involving 52 students from the Biology Education Study Program at Tadulako University, with 26 students assigned to the control group and 26 to the treatment group. SRL data were collected using a questionnaire adapted from the Motivated Strategies for Learning Questionnaire (MSLQ), comprising five subscales: metacognition, time and study environment management, effort regulation, elaboration, and help-seeking. Students in the treatment group received YouTube links to lecture recordings via WhatsApp within 24 hours after each session, whereas those in the control group attended lectures without access to the recordings. Analysis of Covariance (ANCOVA), with pretest scores as the covariate, showed a significant difference in posttest composite SRL scores between the groups (F(1,49) = 32.806; p < 0.001; η²p = 0.401). Significant effects were also found for metacognition (η²p = 0.394), time management (η²p = 0.173), effort regulation (η²p = 0.153), and elaboration (η²p = 0.100), while help-seeking showed no significant difference. These findings suggest that providing lecture recordings through familiar and easily accessible platforms is an effective low-cost pedagogical strategy for enhancing students’ SRL in online learning environments with infrastructural constraints. Therefore, lecture recordings should be considered by lecturers and study program administrators when designing online instruction that supports students’ autonomous learning.

Abstract

Salmonella spp. are Gram-negative rod-shaped bacteria commonly found in the gastrointestinal tract of humans and animals and are recognized as one of the major causes of foodborne diseases. This study aimed to identify the presence of Salmonella spp. in gado-gado sold in the canteens of Tadulako University. This research employed a descriptive exploratory laboratory design. Samples were collected from five different canteens using a random sampling technique. Microbiological analyses were conducted through presumptive and confirmatory tests using the Most Probable Number (MPN) method, Total Plate Count (TPC), Gram staining, cultivation on selective Salmonella–Shigella Agar (SSA), and biochemical testing using Triple Sugar Iron Agar (TSIA). The MPN results showed an average value of 4,900 MPN/mL of sample, while the TPC reached 35,800/ml sample. These values indicate that the food product does not meet the microbiological safety standards established by the Indonesian Ministry of Health, as the TPC exceeds the maximum permissible limit of 104 CFU/mL.
