Perbandingan Hasil Belajar Biologi yang Diajar Menggunakan Model Cooperative Integrated Reading And Composition (CIRC) dengan Model Pembelajaran Langsung Berdasarkan Keterampilan Berpikir Kritis Siswa Kelas X SMA Negeri 4 PALU
Get PDFThe study aimed, to describe the difference of students’ learning outcomes of (1) cooperative integrated reading and composition (CIRC) and direct instruction on biology subject, (2) describe the different of critical thinking high level and the lowest by student learning outcomes. This study using quasi experiment. All students in grade 10 who enrolled 2013-2014 would become research subject. The sample of this research consisted of two classes: X MIA5 and X MIA6. The results showed that the comparison between the two learning models can be seen with the magnitude of the significant probability value < 0.05. There is also a difference between the learning outcomes of students who have highest critical thinking skills with students who have the lowest, where the average of each value 55.63 and 38.42 or significant probability value < = 0.05. It could be concluded, that the student who have the highest critical-thinking skills were taught by using both learning models was better learning-outcomes than the lowest

Sambung Pucuk Dini Pada 5 Jenis Klon Kakao (Theobroma cacao L.) Dengan Umur Batang Bawah Yang Berbeda
Get PDFThe aimed of this research were to determined the suitable of rootstock age for each cacao clone on the early grafting technique, to determined the best of cacao clone with great succesfull on early grafting technique and to obtain the best rootstock age for early grafting technique. The research was conducted during period of January to April 2015 at Laboratory of Forestry Sciences, Forestry Faculty, Tadulako University. This research was arranged based on completely randomized design with factorial treatments. The treatments consists of two factors, the first was superior cocoa clones as the entries and the second was the various age of rootstock. The output data was analyzed by Analysis of Varian and Duncan Multiple Range Test at 5%. The result showed that the suitable of rootstock age for each clone on the early grafting of cacao plant was not presented. Clone M01 had the best growth response in all observed variable. The average growing speed were 10,44 days after grafting. The percentage of success grafting was 100%, the number of shoots were 6,22, the number of leaves were 11,33 leaves, and shoot diameter was 0,40 mm. The two weeks-rootstock reflected better responses in all observed variable, where the average growing speed was 10,40 days after grafting, the percentage of living graft was 100%, the number of shoot was 5,20, the number of leaves was 10,67 leaves and shoot diameter was 0,33 mm

Get PDFThis research applied qualitative research which used descriptive method in order to describe the general epistemological beliefs of middle school students in two schools with different academic levels. The subjects of this research were the eleventh graders of SMA Al-azhar Palu and six the ninth graders of SMP Al-azhar Palu. The selection of respondents and the collection data of epistemological beliefs using EBAPS (Epistemological Beliefs Assessment for Physics Science). Interviews were carried out to elicit students' epistemological beliefs information. Analysis showed that the two academic levels have the same beliefs on dimensional Structure of Scientific Knowledge (SSK), Nature of Knowing and Learning (NKL) and Real-Life Applicability (RLA), and have different beliefs on Evolving dimensions of Knowledge (EK) and Source of Ability to Learn (SAL)
Produksi Antosianin Tersalut Maltodekstrin Dari Kelopak Bunga Rosella (Hibiscus Sabdariffa, L.) Dan Aplikasinya Dalam Pengolahan Pangan Fungsional
Get PDFProduction of anthocyanin maltodextrin coating from roselle’s petals (Hibiscus Sabdariffa,L.) and application in processing functional food has been investigated. The objective’s of research were : (1) To find out extract ratio of roselle’s petals to maltodextrin which is produce anthocyanin maltodekstrin coating which has a high degree of purity and stability. (2) To find out the concentration of anthocyanin maltodextrin coaty in seaweed syrup which was produced syrup with organoleptic properties. Design of this research used one factor complete random design and group random design one factor complete random design to applied in handling influence of anthocyanin dark extract ratio of roselle’s petals to maltodextrin (v/b) (1:1; 2:1; 3:1; 4:1; and 5:1) and group random design applied in organoleptic test of functional seaweed syrup which added by various concentration of coated anthocyanin maltodextrin about (g/100 mL) (0.125; 0.25; 0.375; 0.5 and 0.625) anthocyanin and tested by 30 untrained panelist. Total analysis of coated anthocyanin maltodextrin conducted every 1 week for 8 weeks starting at week 0 using spektrofotometer UV-VIS method at 535 nm wavelength. The result of the influence of coated anthocyanin maltodextrin ratio showed anthocyanin number (highest), degree of purity (highest), and the smallest decrease in retention during storage was ratio 5:1 (v/b), then with this ratio 5:1 conducted prediction of shelf life or expiration period using kinetics reaction model, so that expiration period of coated anthocyanin maltodextrin is 28 weeks. For the best organoleptik quality of functional seaweed syrup consistently is application of coated anthocyanin maltodekstrin with anthocyanin concentration is 0,625 g/100 mL

Pengaruh Model Pembelajaran Inkuiri Dan Gaya Kognitif Terhadap Hasil Belajar Matematika Siswa Kelas VIII SMP Negeri 2 Palu
Get PDFThis study aims to explain the influence of models of inquiry learning and cognitive styles of students towards mathematics student learning achievements. This study is a quasi-experimental design with factorial 2 × 2. The independent variable in this study is the inquiry learning and direct instruction. Cognitive styles of students is divided into two parts, namely the cognitive style field independent (FI) and cognitive style field dependent (FD). The dependent variable is the result of students' mathematics learning. The instrument used was GEFT test used to determine students' prior learning styles koognitif implemented and achievement test used to measure the learning achievements of students after learning mathematics implemented. Samples were students of class VIII SMP Palu Negeri 2 theconsist of 48 students were taken by purposive sampling technique. Data were analyzed using ANOVA analysis of two-path. The results showed that (1) there is an interaction between the model and style koognitif inquiry learning on learning achievement outcomes of mathematics, (2) there is a difference between students' mathematics learning achievements by inquiry learning model and the learning achievements of students who received direct instruction on a group of students who have FI force, (3) there are differences in mathematics learning achievements of students who received the inquiry learning model and who received students learning directly to the student groups which share FD cognitive styles, (4) there are differences in mathematics learning outcomes of students between who have cognitive styles FI and students who have the cognitive styles of students who obtain the FD on inquiry learning, (5) there are differences in mathematics learning achievements students’, among students who have cognitive styles FI with students who have the cognitive style FD on students who received direct instruction
