Abstract

This study aims to measure the effectiveness of using ethnochemistry-based Adobe Flash learning media using indigenous knowledge on scientific literacy. The study used a quasi-experimental method. The research subjects were 68 students who used ethnochemistry-based Adobe Flash learning media using indigenous knowledge on secondary metabolite material. The research is a quantitative study with pretest and posttest design. Data in the study were collected through tests to determine students' scientific literacy skills, including aspects of knowledge and competence in analyzing scientific phenomena, connecting chemical concepts to existing phenomena, and interpreting data or scientific evidence and questionnaires. Supporting data was obtained through a questionnaire to determine learning media users' opinions. The test was conducted with ten multiple-choice questions and a questionnaire with ten statements using a Likert scale of 1-4. The data analysis technique calculates the average score of test questions that have criteria according to scientific literacy and the percentage of user satisfaction. Based on the research results, the average value of 81.50 for scientific literacy skills on the concept of secondary metabolites with an N Gain of 80% is in a good category, and it is also known that the average percentage of user satisfaction is 83%, in a good category. Based on the hypothesis testing using the right-test, it has a t count of 16,160 and a t table of 2,021. The study concludes that applying ethnochemistry-based Adobe Flash learning media on secondary metabolites is effective for students' scientific literacy. Thus, it could be excluded that interactive media can support students' learning and improve scientific literacy.

Abstract

The experiment was done to find out species, intensity and prevalence of common crap fry from traditional ponds and "longyam" at Sukamulya village, Singaparna, Tasikmalaya. This experiment was conducted at Sukamulya village and Aquatic Biology Laboratory of Fisheries Department, Faculty of Agriculture, Padjajaran University form October 1st 2002 to October 31th 2002. Samples of common carp fry were obtained from six traditional ponds and six "longyam". The survey method was used in this experiment of common carp fry at difference type of pond were based on the Wilcoxon rank sum test. Intensity and prevalence of ectoparasites of common carp fry at traditional ponds and longyam was based on the Kruskal-Wallis test. The result of this experiment showed that eight genera of ectoparasites were found, consisted of three Platyhelminthes: Dactylogyrus (47,01%), Gryrodactylus (3,84%), Transversotrema (0,01%), four Protozoa: Ichtyophthrius (9,59%), Epistylis (1,05%), Trichodina (1,68%) and one Arthopoda: Acarus (0,01%), The intensity of Dactylogyrus was 28,83. Gryrodactylus 4.98, Transversotrema 0,17, Ichthyophthirius 13,51, Epistylis 4,68, Trichodina 25,14 Trichodinella 6,55 and Acarus 0,17. The prevalence of Dactylogyrus is 90,00% Gyrodactylus 44,82%, Transversotrema 0,37%, Ichthyophthirius 42,17, Epistylis 13,17%, Trichodina 82,59%, Trichodinella 17,04 and Acarus 0,37%. Key words: Intensity, prevalence, ectoparasites, common carp fry, traditional pond, "longyam"

Abstract

This study aims to analyze the self-efficacy of students of SMP N 8 Banjar class VIII on the material of additives. Self-efficacy is important as one of the psychological aspects that play a role in learning. Specifically, the role of self-efficacy in learning includes increasing students' self-confidence in understanding difficult material, encouraging motivation to learn with greater effort and persist in facing challenges, helping students set realistic goals according to their abilities, and encouraging the selection of effective learning strategies. The method used is descriptive quantitative with a questionnaire consisting of 27 questions and involving 32 students. Self-efficacy is measured based on 3 dimensions based on magnitude level, generality, strength. The results of the study showed an average value of each dimension, namely: magnitude level (66), generality (70) and strength (63). The overall average value of the self-efficacy dimension is 66 with a sufficient category. The less than optimal study was caused by students' lack of confidence in their abilities, giving up easily if given more complex tasks and low learning motivation. Strategies such as providing positive feedback, real-world problem-based learning, more contextual learning models, and social support that encourage students' self-confidence and resilience in facing academic tasks are recommended. ABSTRAKPenelitian ini bertujuan untuk menganalisis self-efficacy siswa SMP N 8 Banjar kelas VIII pada materi zat aditif. Self-efficacy ini penting sebagai salah satu aspek psikologis yang berperan dalam pembelajaran. Secara spesifik, peran self-efficacy dalam pembelajaran meliputi peningkatan kepercayaan diri siswa dalam memahami materi yang sulit, mendorong motivasi untuk belajar dengan usaha lebih keras dan bertahan menghadapi tantangan, membantu siswa menetapkan tujuan yang realistis sesuai dengan kemampuan mereka, serta mendorong pemilihan strategi belajar yang efektif. Metode yang digunakan adalah deskriptif kuantitatif dengan angket kuesioner sebanyak 27 butir soal dan melibatkan 32 siswa. Self-efficacy  yang diukur berdasarkan 3 dimensi berdasarkan magnitude level, generality, strength. Hasil penelitian menunjukkan nilai rata-rata tiap dimensi yaitu : magnitude level (66), generality (70) dan strength (63). Nilai rata-rata secara keseluruhan dimensi self-efficacy yaitu 66 dengan kategori cukup. Kurang optimalnya penelitian ini disebabkan oleh kurang yakinnya siswa terhadap kemampuan yang dimiliki, mudah menyerah jika diberi tugas yang lebih komplek serta motivasi belajar yang masih rendah. Disarankan strategi seperti pemberian umpan balik positif, pembelajaran berbasis masalah nyata, model pembelajaran yang lebih kontekstual, serta dukungan sosial yang mendorong rasa percaya diri dan ketahanan siswa dalam menghadapi tugas akademik.
