Abstract

This study was inspired by the class X SMA Hidayatullah Batam's poor mathematics learning outcomes, one of which was brought on by teaching strategies that discouraged student participation in the learning process. The purpose of this study was to compare the Team Assisted Individualization learning model assisted by mathematics domino (domat) visualizer with conventinal learning models in terms of the mathematics learning results for class X students at SMA Hidayatullah Batam. This kind of research utilized a posttest-only control group design and was quasi-experimental in nature. Up to 53 pupils from class X at SMA Hidayatullah made up the research population. The experimental class, X MIPA PA (15 students), and the control class, X MIPA PI (15 students), were sampled via purposive sampling. The research instrument was in the form of essay questions where all items were valid and reliable (reliability coefficient 0.927 in the high category). Using one sample t-test and independent sample t-tests the data were analyzed. The results showed: (1) The implementation of the domat-assisted TAI learning model was effective in terms of mathematics learning outcomes with a t-value (4.231) t-table (2.144); (2) the conventional model is ineffective with a t-value (-0.728) ≤ t-table (2.144); and (3) there were differences between the domat-assisted TAI learning model and the conventional model in terms of the outcomes of mathematics learning with a t-value (3.082) t-table (2.048). On the basis of the study's findings, the domat-assisted TAI learning approach is advised as an alternative to learning mathematics. It can help students take an active part in the learning process and improve their learning outcomes.

Abstract

Background: The oxeye snail (Turbo argyrostoma) is a marine gastropod commonly harvested by coastal communities for consumption. Intensive and unregulated harvesting may lead to population decline, raising concerns for ecosystem stability and resource sustainability. This activity directly reduces the population of T. argyrostoma in coastal waters. This study aims to determine the abundance and the correlation between the length-weight and condition factors of T. argyrostoma in the waters of Batam, Riau Islands. Method: This study was performed from September to October 2024. Sampling was conducted at three locations: Kajang Island, Piring Island, and Layang Island. The sampling method conducted was purposive sampling. Water quality measurements were carried out in situ. Abundance was determined based on the number of individuals per unit area. Morphometric data were collected by measuring the body dimensions of T. argyrostoma using digital callipers. Next, the length-weight relationship was analysed using linear regression to determine growth patterns. Results: The aquatic environment met the quality standards set by the Minister of Environment, as outlined in Decree No. 51/2004. The highest abundance of T. argyrostoma was observed at Kajang Island (1.37 ind/m²). Morphometric measurements showed mean shell length (SL) of 39 ± 4.83 mm, weight (W) of 21.3 ± 4.58 g, and shell width (SW) of 30.3 ± 3.25 mm in Layang Island samples. A positive length–weight relationship was identified at all stations (r = 0.73, 0.45, 0.78) with allometric growth coefficient (b) values indicating growth patterns. Condition factors (K and Wr) varied across locations: 6.766 and 70.340 at Piring Island; 6.518 and 103.984 at Kajang Island; and 6.229 and 101.037 at Layang Island, respectively. Conclusion: A positive length–weight relationship was observed at all sites, and variation in condition factors suggests differing ecological pressures. The low Wr value at Piring Island may indicate environmental stress or higher predation pressure.

Abstract

Lola snails (Rochia niloticus) are biota that are widely consumed by coastal communities in Batam waters. Even though it is not a favored commodity, exploitation that does not consider sustainability can lead to population scarcity in nature. This research aims to collect comprehensive data regarding the abundance, morphometrics, and weight-length relationship of Lola snails in the waters of Sarang Island, Batam. Sampling was carried out at 3 locations, including Kajang, Piring, and Layang Islands. The Lola snail sampling method was carried out using purposive sampling. Water quality measurements are carried out in situ. Morphometric data were collected by measuring the body dimensions of Lola snails using digital calipers. Abundance was determined based on the number of individuals per unit area, and the length-weight relationship was analyzed using linear regression to determine growth patterns. The research results show that the condition of the aquatic environment still meets the environmental quality standards set by the Ministry of Environment No. 51 of 2004. The abundance of Lola snails was in range of 0.22- 0.97 ind/m2, and the highest was found on Kajang Island. The results of morphometric measurements showed that the highest shell length, weight, and shell width were observed in Lola snail samples from Kajang Island with values of 48.40 25.28 mm, 68.77 101.55 mg, and 44.42 23.28 mm. There is a relationship between the growth patterns of Lola snails caught at three stations which have negative allometric growth patterns, where Kajang Island, Piring Island, and Layang Island have negative allometric growth patterns (b3) with exponential values of 0.9685, 1.5121, and 2.5471, respectively. The value of relative weight condition factor (Wr) shows a value close to 100 on Kajang, Piring, and Layang Island, namely 102.753 and 104.812, 99.654, which indicates that Lola snails were in good condition during the research.
