Abstract

The research aims at developing Natural Science Subject Instructional packages of year XI Semester 1 SMK Negeri 5 Palu by employing Dick, Carey & Carey Model. The research employed Research Development (R&D) design. The instructional package drafts that have been previously developed were validated by a content expert, a design expert, and a media expert. The revised version of the packages were tried out into three different subjects; individual, small group, and big group which contained 25 students and 1 teacher. Questionnaire designed in Likert Scale was used as the instrument of data collection. Suggestion, input and comment during consultation period were also noted and used to compliment the collected data from the questionnaire. The results of the data analysis show that 1) the instructional materials product score ranges from 81.33% to 83.80% indicating that the instructional material is classified Good and Very Good, 2) the teacher’s book product score ranges from 80.00% to 91.25% indicating that the teacher’s book is classified Good and Very Good, 3) the student’s book product score ranges from 80.00% to 94.67% indicating that the student’s book is classified Good and Very Good. Based on Kuswadi’s argument (in Sudarman, 2006) if the developed instructional packages scored higher than 71%, the products are ready and valid to be used. The achievement of the students, between the pretest and the posttest, during the instructional materials try out is different significantly calculated by applying t-test formula. It implies that the instructional packages have been valid and ready to be used.

This research aims to determine the effect of product, price, place and promotion Against sales volume of fried onion in Palu. The population in this research as many as 52 industry fried onions. The total sample as many as 34 industries that considered representative of the population. Data were analyzed using multiple linear analysis. The analysis showed that the value Ftest (9,815) > Ftabel (4,04), this means that the independent variable (Xi) simultaneously the effected significantly toward dependent variable (Y). The coefficient of determination (R²) equal to 0.775 atau 77,50%, which means that the industry's sales volume fried onions (Y) may be described or explained simultaneously by the product variable (X1), price (X2), place (X3), and promotion (X4), while the remaining 22,50% is explained by other variables not included in the model.

Abstract

This 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.

Abstract

The 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.

Abstract

This research was aimed to determine the best based medium containing BAP in Melaleuca cajuputi propagation at the initiation stage, and to obtain the best growth of cajuputi plantlets during acclimatization stage. The experiment was arranged in completely randomized design, which consists of two experimental stage, cajuputi bud initiation and cajuputi plantlet acclimatization. At the initiation stage, the tested treatment were combination of based medium (WPM and MS) and Cytokinin (BAP). While at the acclimatization stage, plantlets from each treatment of initiation stage were grown in soil medium. This research was conducted over May to December 2014 at the Laboratory of Forest Biotechnology, Forestry Faculty Tadulako University. Data were analyzed by Analysis of Varian and the differences between treatments were determined by Duncan Multiple Range Test (DMRT). The outcome of this research showed that WPM based medium containing 0.7 ppm BAP had the best responses to the growth of cajuputi planlet (Melaleuca cajuputi) at the initiation stage. Application of Woody Plant Medium (WPM) based medium contained 0.7 ppm BAP at the initiation stage, give the optimal responses to the growth of Eucalyptus planlet (Melaleuca cajuputi) during the acclimatitation stage.
