Abstract

This research aims to describe the kinship relationship of baronang fish species, based on morphological character analysis. The approach used is descriptive explorative. Research samples were obtained from the sea waters of Labean Village, Donggala Regency using purposive sampling techniques. The obtained baronang fish were then identified and measured based on 21 morphometric characters, 5 meristic characters, and 4 qualitative characters in each of the six species found. Data is processed using Microsoft Excel then analyzed using cluster analysis on MVSP (Multivariate Statistical Package) software. The similarity index uses the Simple Matching Coefficient method, the reconstruction of the dendogram using the UPGMA algorithm. The results of this research found six species of baronang fish, namely: Siganus canaliculatus, Siganus doliatus, Siganus vulpinus, Siganus vermiculatus, Siganus guttatus, and Siganus puellus. The kinship relationship between six types of baronang fish is formed into five clusters with various kinship categories, namely very close, close, and not close. The first cluster shows a very close kinship occupied by Siganus canaliculatus with Siganus doliatus with a similarity index of 0.93%. Meanwhile, the fifth cluster that shows not close kinship is the grouping between fish species on Node 4 with fish species on Node 3 with a similarity index of 0.43%. The results of this research, are expected to be the basis for further research related to kinship or the development of baronang fish species in Labean Village, Donggala Regency.

Abstract

This study aimed to analyze the effects of combining kinetin and picloram on the in vitro shoot development of vanilla. The research was conducted at the Plant Tissue Culture Laboratory, Faculty of Mathematics and Natural Sciences, Universitas Negeri Semarang, from July to November 2024, using a Completely Randomized Design one factorial with 16 treatment combinations and five replications. One nodal explants were taken from the 1st to 6th of Vania variety vanilla plantlets. Parameters observed included days to shoot emergence, shoot growth percentage, shoot length, root length, number of roots, and number of leaves. Data were analyzed using the Kruskal-Wallis test. The results showed that the combination of kinetin and picloram had a significant effect on all observed growth parameters. The treatment without the addition of plant growth regulators (kinetin 0 ppm + picloram 0 ppm) produced the best results across all parameters. Other treatments without picloram also exhibited good growth in at least three main parameters. Therefore, the combination of 0 ppm kinetin and 0 ppm picloram was the most optimal treatment for supporting the in vitro growth of vanilla explants.

Abstract

This study aims to analyze the protective potential of Bidens pilosa L. leaf ethanol extract against histological damage to the lungs of white rats (Rattus norvegicus) due to alcohol exposure. This study is an experimental research using five treatment groups, consisting of a negative control, a positive control (alcohol), and three groups administered alcohol combined with Bidens pilosa L. leaf ethanol extract (EEDK) at varying doses. The parameters observed include edema, alveolar septum destruction, and inflammatory cell infiltration in lung histology specimens. Data were analyzed using one-way ANOVA followed by DMRT. The results showed that EEDK administration significantly reduced lung damage, as indicated by a decrease in the average damage score from 43.12 ± 0.18 in the alcohol group to 33.92 ± 1.65 (250 mg/kgBW), 23.32 ± 2.18 (500 mg/kgBW), and 14.88 ± 1.06 (750 mg/kgBW). The reduction in lung damage included improvement in edema, reduction in alveolar septal destruction, and suppression of inflammatory cell infiltration. These findings suggest that ethanol extract of Bidens pilosa L. leaves has potential as a natural protective agent through its anti-inflammatory and antioxidant activities, thereby potentially useful for preventing or reducing alcohol-induced lung damage.

Abstract

This study aims to investigate the effectiveness of the integrated Problem-Based Learning (PBL) model with the Flipped Classroom approach on students’ problem-solving skills in biology learning for Grade XI Phase F at SMAN 1 Kota Jambi. The main issue addressed in this research is the suboptimal implementation of the PBL model in the classroom due to limited instructional time. This study employed a quasi-experimental design using the nonequivalent pretest-posttest control group design. The research was conducted at SMAN 1 Kota Jambi during the even semester of the 2024/2025 academic year. The population consisted of Grade XI Phase F students, with Class XI F2 assigned as the experimental group and Class XI F7 as the control group, selected through purposive sampling and random sampling techniques. Data were collected using observation sheets and essay test instruments. The research data were analyzed using a One-Way ANCOVA test. The results indicated a significant difference between the experimental and control groups based on the One-Way ANCOVA test results [F(1,69) = 53.941, p < 0.001, ηp² = 0.439]. The obtained Partial Eta Squared value of 0.439 demonstrates a significant difference between the integrated Problem-Based Learning with Flipped Classroom model and the conventional Problem-Based Learning model. Based on these findings, it can be concluded that the integration of the Problem-Based Learning model with the Flipped Classroom approach is effective in enhancing the problem-solving skills of Grade XI Phase F students at SMAN 1 Kota Jambi.

Abstract

This study aims to analyse the effect of online game addiction on students' learning motivation at SMP PKMI Methodist Aek Batu. This research uses a quantitative approach with survey method. The population consisted of 64 students, and the total sampling technique was used to determine the sample. The research instrument is a questionnaire that has been tested for validity and reliability. Data analysis was performed using Pearson's correlation test with IBM SPSS Statistics 23. The results of the study showed that there was no significant effect of online game addiction on student learning motivation, as evidenced by the correlation test results showing a significance value greater than 0.05 (> 0.05). This discrepancy in results may be influenced by factors such as time management, parental support, type of game, and the students' social environment. Therefore, it can be concluded that online gaming addiction does not directly affect students' learning motivation at SMP PKMI Methodist Aek Batu. Further research with a broader scope, larger sample size, and a mixed quantitative and qualitative approach is recommended to obtain more comprehensive results.

Abstract

This study aimed to analyze the effect of combined picloram and kinetin treatments on callus induction from young leaf roll explants of sugarcane variety Bululawang. The experiment was conducted using a completely randomized design with one factor consisting of 16 treatment combinations of picloram (0, 2, 4, and 6 ppm) and kinetin (0, 0.5, 1, and 1.5 ppm). The observed parameters included the time of callus initiation, percentage of explants forming callus, fresh weight, dry weight, and callus morphology. The results showed that the addition of picloram and kinetin combinations did not significantly affect the time of callus initiation but significantly increased the percentage of explants forming callus (averaging 86.72%) compared to the control (12.50%). The highest fresh and dry weights of callus were recorded at the treatment of 4 ppm picloram + 1 ppm kinetin, with a fresh weight of 0.4412 g and a dry weight of 0.0650 g. Callus morphology was predominantly compact in texture with a yellow to yellow-reddish color. The combination of picloram and kinetin effectively increased the percentage of callus induction, fresh weight, and dry weight of callus in sugarcane, indicating its potential application in tissue culture and secondary metabolite production.

Abstract

This study aims to document the traditional knowledge of the local community in Kaloy Village, Tamiang Hulu Subdistrict, Aceh Tamiang Regency regarding the use of medicinal plants for treating circulatory system disorders. The methods used include in-depth interviews, direct observation, and documentation involving 90 respondents from various age groups and two key informants. The results show that the community's trust in medicinal plants remains high, particularly among individuals aged over 50. A total of 10 plant species were identified and used to treat diseases such as hypertension, high cholesterol, anemia, stroke, and diabetes. The most commonly utilized plant parts were leaves and rhizomes, with traditional processing methods such as boiling, pounding, and chewing. The study also calculated the Index of Cultural Significance (ICS) to assess the cultural importance of each species in the community. These findings indicate that ethnobotanical knowledge is still well preserved among the older generation but is beginning to decline among the youth.
