Analisis Literasi Kimia Peserta Didik melalui Pembelajaran Inkuiri Terbimbing Bermuatan Etnosains

Abstract: Penelitian ini bertujuan untuk menganalisis kemampuan literasi kimia peserta didik melalui penerapan model pembelajaran inkuiri bermuatan etnosains pada materi hidrolisis garam. Metode penelitian yang digunakan adalah studi kasus dengan desain penelitian One-Shot Study Case. Pengambilan sampel pada penelitian ini menggunakan teknik purposive sampling. Pengumpulan data menggunakan metode tes dan metode angket. Metode tes berupa soal literasi kimia berbentuk pilihan ganda dengan jumlah soal sebanyak 25 butir soal yang sebelumnya sudah diuji validitas dan reliabilitasnya. Metode tes bertujuan untuk mengetahui kemampuan literasi kimia peserta didik pada aspek konten, konteks, dan kompetensi, serta metode angket untuk mengetahui sikap peserta didik terhadap kimia. Hasil penelitian menunjukkan bahwa rerata kemampuan literasi kimia peserta didik pada sapek konten, konteks, dan kompetensi berada pada kategori kurang, sedangkan untuk aspek sikap peserta didik terhadap kimia dalam kategori sangat baik. Hasil penelitian disimpulkan bahwa setelah penerapan model pembelajaran inkuiri bermuatan etnosains kemampuan literasi kimia peserta didik berada dalam kategori cukup.e

Influence of Guided Inquiry Model on Students Cognitive Learning Outcome in Stoichiometrytopic

Abstract: Teacher as a facilitator is expected to explore the potential of students to be able to master the material with minimal mastery. This research aims to understand the concept of students' increased understanding of the material stoichiometry with guided inquiry learning model application. Experimental research conducted in SMAN 6 Semarang. The research sample is determined by purposive sampling class X MIPA 7 (an experimental class with 36 students) and Class X MIPA 8 (a control class with 36 students). Theused instrument is a cognitive achievement test. Analysis of students' cognitive learning outcomes data using the N-gain average test obtained 80.94%, with the average of an experimental group of students by 83.00% and theaverage of control group students by 76.94%. Achievement of experimental class minimum completeness criteria 91.67% and a standard deviation of 6.21 is higher than the minimum completeness criteria for achievement grade control by 69.44% and a standard deviation of 7.38. The t-test analysis obtained t value of 57.61 is greater than t table at a significance level of 0.05 by 2.03. The results of the analysis stated that there is significant influence guided inquiry learning model application of the cognitive achievement of students on the concept of stoichiometry.

Pengaruh Analisis Kebangkrutan Model Altman Terhadap Harga Saham Perusahaan Manufaktur

Abstract: This study aims to help investors determine the health of companies listed in DES during 2008-2013 period by using the first model of Altman Z – Score, Z = 12 X1 + 14 X2 + 33 X3 + 06 X4 +0999 X5, and analyze Z - Score influence on stock prices The stock price was taken on 28 th day after the company published financial statements 36 manufacturing companies were sampled by purposive sampling Z - Score calculation results showed that there were 2 potentially bankrupt companies, 9 companies in grey category, and 25 other companies are healthy Simple regression analysis results showed that the value of the Z - Score does not affect the stock price However, the result of the simultaneous multiple regression analysis on financial ratios of the Z - Score affects the stock prices, partially showed the ratio of WC/TA and S/TA negatively affect the stock price; ratio EBIT/TA have a positive effect on stock prices; ratio of RE/TA and MVE/BVD has no effect on stock prices Keywords: Altman Z - Score, Financial Ratios of Z - Score, Share Price Abstrak Penelitian ini bertujuan untuk membantu investor mengetahui tingkat kesehatan perusahaan manufaktur yang terdaftar dalam DES periode 2008-2013 dengan menggunakan model Altman Z-Score pertama yaitu Z = 1,2X 1 + 1,4X 2 + 3,3X 3 + 0,6X 4 +0,999X 5 dan menganalisis pengaruh Z-Score terhadap harga saham Harga saham diambil hari ke-28 setelah laporan keuangan perusahaan dipublikasikan 36 perusahaan manufaktur diambil sebagai sampel berdasarkan purposive sampling Hasil penghitungan Z-Score menunjukkan terdapat 2 perusahaan berpotensi bangkrut, 9 perusahaan masuk kategori grey / rawan, dan 25 perusahaan lainnya sehat Hasil analisis regresi sederhana menunjukkan nilai Z-Score tidak berpengaruh terhadap harga saham Namun, hasil analisis regresi berganda secara simultan rasio keuangan pembentuk Z-Score berpengaruh terhadap harga saham, secara parsial menunjukkan rasio WC/TA dan S/TA berpengaruh negatif terhadap harga saham; rasio EBIT/TA berpengaruh positif terhadap harga saham; rasio RE/TA dan MVE/BVD tidak berpengaruh terhadap harga saham Keywords : Altman Z-Score , Rasio Keuangan Pembentuk Z-Score , Harga Saham

The effectiveness of nature-based practicum worksheet on acid-base titration material towards students’ science process skills

Abstract: The study aimed to find out the eligibility, effectiveness, and practicality of Nature-Based Student Practicum Worksheet on Acid-Base Titration towards students' Science Process Skills Research and Development method was used in this study The research was conducted at SMAN 1 Kendal The result of the validation assessment showed that the developed worksheet was eligible, with an average score, given by the validators, was 8958% for its materials and 9028% for its media The analysis result of the students' science process skills in performing practicum activities showed that 60 students reached a "very good" category and 9 students reached a "good" category; and the result of evaluation test revealed that 62 out of 69 students passed the minimum passing criteria (≥75) The reliability of the questionnaire for the students' responses was also tested; and it was revealed that its reliability was 089 According to the validation stage, the test results on a small and a large scale showed that the nature-based practicum worksheet on acid-base titration material towards students' science process skills was eligible, effective, and practical to be implemented
