Abstract

The purpose of this study was to analyze the effect of web-based science teaching materials with the context of local wisdom on higher-order thinking skills (HOTS) and cultural care attitudes of students. The non-equivalent post-test-only control group design is the quasi-experimental design used. The study population included 140 grade VII SMPN 16 Mataram students, with a total sample of 35 students in the experimental class and 35 people in the control class. Data were obtained from the HOTS test instrument and a cultural caring attitude questionnaire which were analyzed using one-way MANOVA descriptive statistics. The HOTS test consists of 20 multiple-choice questions and a cultural care attitude questionnaire with 12 statements. The results showed that the average HOTS score of students in the experimental class was 83.75 while in the non-experimental class (the control class) it was 74.29. The average value of students' cultural attitudes in the experimental class was 91.61 while in the control class, it was 88.39. This means that HOTS and students' cultural care attitudes are superior in the experimental class compared to the control class. Based on the Multivariate tests, an F value of 20.32 was obtained with a significance much less than 0.05. This means there were differences in HOTS and cultural awareness between students who used web-based science teaching materials in the context of local wisdom and those who used conventional science teaching materials. Thus, using web-based science teaching materials in the context of local wisdom has an effect on HOTS and the attitude of caring for the culture of students. Web-based science teaching materials with the context of local wisdom can be an alternative contextual learning resource that plays an important role in strengthening character education, especially caring attitudes.

Abstract

The use of inorganic fertilizers in high doses for chili pepper (Capsicum frutescens L.) cultivation can negatively impact plant productivity over time. This study aimed to evaluate the effectiveness of chicken manure (CM) and foliar fertilizer (FF) in reducing the reliance on inorganic fertilizers for chili pepper plants grown in dryland conditions. The experiment was conducted in Gumantar Village, North Lombok Regency, from March to August 2023. As the control, an inorganic fertilizer treatment with NPK (16-16-16) at a dose of 1,200 kg/ha was used. The tested treatments included 85% NPK + CM, 70% NPK + CM, 55% NPK + CM, 85% NPK + CM + FF, 70% NPK + CM + FF, and 55% NPK + CM + FF. The dose of chicken manure applied was 20 tons/ha. These treatments were arranged using a randomized block design with three replications. The results indicated that CM, with or without FF, could increase the percentage of flowers that developed into fruits. There were no significant differences in the growth and yield of chili plants among the various treatments, suggesting that CM, with or without FF, could effectively replace up to 45% of the inorganic fertilizers used. This finding indicates that the dependence on inorganic fertilizers in chili pepper cultivation in drylands can be gradually reduced by incorporating organic and foliar fertilizers

Abstract

Siamese catfish (Pangasius hypophthalamus) is one of the most economically importantfreshwater commodities in Indonesian aquaculture. A major challenge during the growth-out phase, is the limited ability to digest plant-based diets due to high cellulose and crude fiber content, which reduce feed digestibility. Supplementation of cellulase in feed has been proposed as a strategy to improve nutrient utilization. Therefore the present study investigated the effect of dietary celulase supplementation on feed digestibility and growth performance in Seamese catfish. Juvenile catfish with an average initial length of 6cm were reared for 30 days in floating net in a cement pond. A complete reandomized design was employed with four treatments, two control, and four replciates. Treatments included cellulase derived from mivrobes sources T1 = Plant feed + WT, T2 = Plant feed + (WT + SKIK), T3 = Plant feed + Mutant, T4 = Plant feed + (mutant + SKIK). The control consisted of C1 = Commercial feed and C2 = Plant-based feed without enzyme supplementation. The results showed that C1 showed the best results for the growth of fish. However, T2, T3 and T4 showed the best results when compared to C2 and T1 which used 100% vegetable protein feed. Therefore, it can be concluded that the addition of cellulase enzymes to the feed has an effect on increasing the growth of Siamese catfish.

Abstract

Data from the Global Youth Tobacco Survey shows that although 78.9% of students received information about the dangers of smoking, high smoking prevalence remains among adolescents. This study aims to evaluate the effectiveness of the AISAS model in improving adolescent knowledge about smoking prevention through the social media platform TikTok. Using a one-group pre-test-post-test design in a quantitative approach, this study involved 54 seventh-grade students as  sample using a proportionate stratified random sampling method. Data collection was conducted through questionnaires distributed before and after the intervention. Data analysis involved univariate and bivariate approaches, including the Paired Sample T-Test and Wilcoxon Signed Rank Test. The main finding was a significant increase in respondents' knowledge from pre-test (0%) to post-test (100%) after the intervention. Analysis using the Wilcoxon test showed a p-value of 0.000 (p < 0.05), indicating a significant effect of the intervention. Activities such as liking, commenting, and posting twibbons had a significant positive correlation with increased knowledge, with the activity of posting twibbons showing a B coefficient of 1.025 (p = 0.025). The results of this study indicate the importance of active involvement in social media as a key factor in increasing adolescent knowledge regarding smoking prevention
