Abstract

This paper aims to examine the role of in vitro culture as a technique to produce secondary metabolites that are needed in various fields. In addition to producing secondary metabolites, in vitro culture can also be used as a plant conservation technique that can produce plantlet asexually in large numbers. This large number of plantlets besides being commercialized, its growth and development of plants is useful for overcoming the decline in environmental quality. An example of a plant will be useful as the lungs of an area and its roots will reduce the erosion of land areas. The conceptual framework of this study is that in addition to producing secondary metabolites, in vitro culture also has a function for plant conservation which in the future can prevent environmental damage. The problem in this study is the instability in the secondary metabolite biomass production and the need for optimization in the domain of conservation techniques. The method of this paper writing was extracting data information from journals, books and online sources which being analysed descriptively and qualitatively to verify the data objectively. The result of this study showed the role of in vitro culture that can produce secondary metabolites and can be implemented in plant conservation that overcome environmental crises.

Abstract

This research aims to determine the best dose of KCl fertilizer and humic acid for peanut yields. The study was conducted using a split-plot design with two factors, and each factor was repeated three times. The dose of KCl as a subplot consisted of 4 levels (0, 50, 75, and 100 kg/ha), while humic acid as the main plot consisted of 4 levels (0, 10, 20, and 30 kg/ha). Observation included the number of non-productive gynophores, the number of pods, dry weight harvest yield (pods per plant, pods per plot, seeds per plant, and seeds per plot), and the weight of 100 seeds. The single factor of KCl dosage significantly affected the dry weight of pods per plant, dry weight of seeds per plant, and dry weight of seeds per plot. The single factor of humic acid treatment had no significant effect on all observation variables, while the interaction of KCl and humic acid doses significantly affected the number of non productive gynophores and the weight of 100 seeds. The best dosage was 100 kg/ha, producing the highest yield with a dry seed weight per plot of 147.43 g. The combination of KCl 75 kg/ha and humic acid 30 kg/ha produced peanuts with the best quality, with weight 100 seeds of 39.47 g. Keywords: Humic acid, KCl, Peanut, Potassium, Yield.

Abstract

Melon (Cucumis melo L.) is a fruit known for its sweet and refreshing taste. Traditionally, melon cultivation has relied on conventional farming methods. The use of biofertilizers offers an alternative to reduce dependency on synthetic fertilizers. This study aimed to enhance the production of healthy, high-yielding melon plants by substituting Mutiara NPK fertilizer with Bioto Grow Gold (BGG) biofertilizer. Conducted in Sukosongo Village, Kembangbau District, Lamongan Regency, East Java, the experiment employed a factorial Completely Randomized Design (CRD).Two factors were tested: BGG fertilizer at four concentrations (0 ml/L [P0], 1 ml/L [P1], 2 ml/L [P2], and 4 ml/L [P3]) and NPK fertilizer at four doses (0 g/plant [N0], 60 g/plant [N1], 70 g/plant [N2], and 80 g/plant [N3]). Results indicated that BGG fertilizer influenced both vegetative and generative growth variables, as did the Mutiara NPK fertilizer doses. The optimal combination was achieved with a BGG concentration of 3 ml/L and an NPK dose of 70 g/plant, which significantly increased the sucrose content in melons. Keywords: Bioto Grow Gold fertilizer, Biofertilizer, Melon, NPK Mutiara fertilizer.

Abstract

This study aims to develop and evaluate bilingual (Indonesia-Malay) mathematics comics designed to increase the learning interest of Indonesia students in Malaysia. Using a Research and Development (R&D) approach with the ADDIE (Analysis, Design, Development, Implementation, Evaluation) model, this study involved 7 students from the Indonesian Community Centre (ICC) in Muar, Johor. The effectiveness of bilingual comics was evaluated through measuring students' interest before and after the intervention using a Likert scale questionnaire. The validity of the comic content was assessed using Aiken's V, then the results showed that all aspects of the comic (material, media, and language) had good validity with an Aiken's V value > 0.70. The data were analyzed for normality and homogeneity, followed by a paired t-test to compare the pre test and post-test scores. The results showed that the use of bilingual comics significantly increased students' interest in learning, with a t-statistical value of 5.227, p = 0.002, and Cohen's d of -1.976, indicating a large measure of effect. These findings show that bilingual math comics can increase students' interest in learning mathematics.

Abstract

Fig cuttings often face problems with failure of the roots to grow from the cuttings, so efforts are needed to encourage root induction by administering auxin growth regulators. Rootone F is an exogenous PGR from the auxin group which can stimulate root growth. In order for the roots to grow, develop and function well, plants need an ideal planting medium. The ideal planting medium to support good growth of plant seeds is a proportional composition of physical, chemical and biological elements. The aim of the research was to examine the combined effect of Rootone F concentration and planting media composition on the vegetative growth of fig cuttings. The research consisted of two treatment factors, namely the concentration of Rootone F (0 ppm (Control), 100 ppm, 150 ppm and 200 ppm) and the composition of the planting media (soil: husk charcoal: cow manure) with a ratio (1:1:1), (2:1:1), and (3:1:1). The best treatment combination is 150 ppm Rootone F and planting media mixed with soil: roasted husks: organic cow fertilizer with a ratio of 3:1:1 which has a significant effect on shoot length, root length, fresh weight of roots and percentage of live cuttings (%). A concentration of 100 ppm Rootone F gave the best results when the first shoots appeared (DAT), a concentration of 150 ppm Rootone F gave the best results on the number of leaves. A planting medium composition of (3:1:1) gives the best results when the first shoots appear (DAT).   Keywords: Auxin, Growth regulator, Influence, Nutrient, Vegetative.

Abstract

The purpose of this study is to analyze the effects of using the discovery learning model with the use of Quizizz media on the academic performance of seventh graders at MTsN 4 in Surabaya City.  The methodology used for this study is known as Classroom Action Research (PTK). The research involved 32 students from Surabaya City's seventh grade E MTsN 4 class. Two cycles were used to conduct the research.  The four phases of a cycle are preparation (preparation), execution (act), oversight (observation), and analysis (analysis). After collecting data using the learning results test technique, we compared the results using a table that categorized the percentage of learning completeness and then evaluated the data based on students' learning outcomes. Learning outcomes significantly improve with each cycle, according to the research. A score of 21.875% in the extremely bad category, 53.125% in cycle I, and 84.375% in cycle II are all indicative of this improvement compared to pre-cycle activity. Students in seventh grade at MTsN 4 in Surabaya City can benefit from using Quizizz media to supplement the discovery learning methodology.
