Abstract

This study aimed to describe the influence of learning model and learning motivation through conceptual understanding students. This research was conducted at Madrasah Aliyah Negeri 1 Palu using a quasy-experimental design with factorial 2 × 2. The independent variable is a learning model and learning motivation. Learning model are problem based learning model and inquiry learning model. Learning motivation investigated that were high learning motivation and low learning motivation. Dependent variable is conceptual understanding students. There was using two instruments, there were (1) a questionnaire of learning motivation that used before learning activity and (2) a test of conceptual understanding students was used after learning activity. These samples included s 48 students at grades X students, who were chosen by random sampling. Analysis of data using analysis of variance two-lane.

Abstract

The problem in this study was the lack of student activities and low learning outcomes of students in science subject at fourth grade SDN Kawatuna Palu. This study was classroom action research consist of two cycles. Each cycle consists of two meetings. The stages of every cycle were planning, action, observation and reflection. By through the six phases of Student Team Achievement Division (STAD) learning, that students activity and student learning outcomes on the material force and motion of objects might increase. The activity of student in first cycle reached 72.7%, (good categories according to Likert scale), teacher activity reached 75% (good categories) and learning outcomes in the form of classical completeness reached 59.4% (enough category). In the second cycle, the student activity reached 84.9% and teacher reached 87.5%, the result of classical completeness increased up to 100%. These results provide a positive impact in improving the activity and student learning outcomes. STAD might made students more familiar and more active in learning. Familiar means that students work together in completing the LKS group, they cooperate by accepting the differences of each member of the group. Active in this case was students more active to ask and answer the question, both of teachers and of other groups at the time of the learning process.

Abstract

The aims of this research are: (1) analyzing the supplies effect, the effective working days, the catching trip, the fishing equipment which affecting the fishermen result in catching fish of Bantaya Village, Parigi Sub-District in Parigi Moutong Regency, (2) Analyzing the fishermen income in bantaya Village Parigi Sub-District in Parigi Moutong Regency. The sample of this research is fishermen in Bantaya village, and then the method used was census method. The instruments of data collection were observation and interview which analyzed through multiple linear regression and income analysis. The result of the research by using multiple linear regression showed that coeffcient of determination (R2) is 0.849. Going through Ftest, it shows that Fcounted = 80.034 > Ftable = 3.695 on α = 1%, it proves that Null hypothesis was rejected. It means that the independent variable (1n X1), labor (1n x2), the number of catching trip (1n X3) the fishing equipment (D) simultaneously affects the result of catching fish in bantaya Village Parigi Sub-District in Parigi Moutong Regency. Furthermore, the fisheries’ income in Kelurahan of Bantaya with the production cost is Rp. 26.208.658,-/ month, which consists of fixed amount is Rp. 16.101.847,-/month and the variable cost is Rp. 10.106.810,-/month, the amount income is Rp. 53.881.207,-/month, so that the amount before sharing profit is Rp. 27.672.549,-/month, while income after sharing profit is Rp. 3.231.213,-/month.

Abstract

The aim of study is to determine the optimal combination between energy and protein levels on feed efficiency, income and (IOFCC) Income Over Feed and Chick Cost of growth phase of super local chiken. The study was conducted in Kawatuna Village, Mantikulore Sub-district, Palu from April 17th to July 17th , 2017. This study used 192 old 1 Day Old Chick (DOC) super local chicken and designed in a Completely Randomized Design (CRD) within factorial design with two factors. The first factor is the metabolic energy consisted of two levels i.e EM1 (2800 kcal / kg) and EM2 (3000 kcal / kg). The second factor is four levels of protein ration ie P1 (18%); P2 (19%); P3 (20%); and P4 (21%). These two factors obtained 8 of treatment combination and repeated 4 times, so there are 32 experiment units. The variables observed were feed efficiency, income, and income over feed and chick cost. The analysis of variance result showed that the interaction between energy and protein produce no significant (P> 0,05) effect to all observation variables. Moreover energy and protein factor also produced no significant (P> 0,05). However a combination between 2800 kcal/kg ME and 18% protein is recommended as optimum diet formulation.

Abstract

The study aims to identify changes in forest cover resulting from forest and land rehabilitation activities using Landsat 8 OLI Imagery in Miu Sub Watershed Area and to formulate the role of the parties to the implementation of forest and land rehabilitation in the Miu Sub Watershed. This research was conducted in Miu Sub Watershed area in Sigi, Central Sulawesi. This research was conducted for 4 months starting from June until September 2017. Data obtained through direct observation to the field, while the role of the parties obtained through the method of purposive sampling. The data were processed using analysis of image interpretation and 4R analysis for the role of the parties. The results show that the success rate of forest and land rehabilitation in the Miu Sub Watershed area is included in either good category until very good. From the result of wide delineation of landsat image 8 it is known that the Miu Sub Watershed area in Namo village has the highest percentage in the implementation of forest and land rehabilitation management of 92% with an area of ​​50 Ha. While the results of 4R analysis indicate that the relevant parties have performed their duties and responsibilities fairly well so that forest and land rehabilitation activities in the Miu Sub Watershed area could be done well.
