Abstract

There are many of learning approaches and methods that could produce an active students in the learning process. The teacher has important role to engage students in the learning process. Discussion method is a kind of teaching method that believed could solve problems by exchanging ideas with mutually consensus among group members and participants. Discussion method is a way of presenting a lesson, where students are faced with a problem, which can be either statements or questions are problematic to be discussed and solved together. Nevertheless, the discussion method are facing the problem in terms of fiqh study areas. Some of students consider trivial and seem less interested in studying the field of fiqh study, so the impact on the results obtained by the students. There were some issues raised in this study: first, to determine the learning plan fiqh by using the method of discussion at High School Darussalam. Second, to examine the implementation of fiqh study by using the discussion method at High School Darussalam. And third, to find out the learning outcome fiqh by using the method of discussion on student High School Darussalam. This research was kind of qualitative researchwhich aimed to describe or analyze the phenomenon, events, social activities, beliefs, perceptions, thoughts people individually or in groups. The tools used are observation, documentation and interview. The finding of the research could be carried out in three phases, planning through the process of preparing teaching materials, syllabus and lesson plans. In this phase of implementation is in accordance with what was previously planned. The planning phases was discussion method preparation until discussion method implementation in some specific material.

Abstract

The mission to observe the Sea Surface Salinity (SSS) from the space is not really new because it has been started from long time ago. The first mission was the Skylab which used a 1.4 GHz microwave radiometer in 1970’s. But this mission is still not as comprehensive as other missions which observe such as Sea Surface Temperature (SST), Sea Surface Height (SSH), Ocean Color, and so on. Realizing the importance of SSS distribution in the ocean and its influences to the Earth’s climate system has motivated the scientists to develop a new technique in observing the SSS from space and lead a mission called the SMOS mission which was launched in November 2, 2011. Besides observing the SSS, this mission observes the Soil Moisture as well. The Soil Moisture and Ocean Salinity (SMOS) mission aims to obtain global and regular measurements on the soil moisture and the ocean salinity. These measurements are essential for climate and hydrological models, among other purposes. SMOS payload is a L band (21 cm, 1.4 GHz) 2D interferometric radiometer on a generic Proteus platform. The mission lifetime is at least 3 years (0.5 for commissioning and 2.5 for normal operation) + 2 years (extended operation) + 10 years for the post-mission processing. Raw physical data, level 1 and level 2 products will be produced by the PDPC (SMOS Payload Data and Processing Centre). It is an ESA center located in Villafranca (Spain) and operated under the responsibility of ESA. The SMOS Ocean Salinity objective is accuracy better than 0.1 psu, with 10 days to monthly grid scale (200 km).

Abstract

The purpose of the study was to evaluate the effectiveness of Project-Based Learning in the Mechanical Engineering Department at the Polytechnic in Malaysia. This study was designed with Context, Input, Process and Product (CIPP) model. Project-Based Learning is a different approach than the traditional learning in the sense that it is a student-centered learning approach based on the principles of constructivism. This study involved a random sample of 118 students and 43 supervisors in the Mechanical Engineering Department in Polytechnic Kota Bharu Malaysia. The instrument used in this study were a set of questionnaire. In terms of finding ideas, both students and supervisors agreed that students were encouraged to assess the real problem by their supervisors. However, the supervisors were uncertain whether the students went to the library to get the ideas for their project. In addition, the supervisors were barely agreed about the creativity of the students in finding the project ideas. However, students and their supervisors believed that critical thinking and creativity were needed in the Project-Based Learning. The respondents also believed that e-SOLMS helped the students to work in group to complete the project.

Abstract

Energy needs in Indonesia in particular and the world in general continue to rise due to population growth, economic growth and energy consumption patterns themselves are constantly increasing. One of the fast growing renewable energy in the world today is wind energy. Wind energy is a renewable energy that is very flexible. In general, the utilization of wind power in Indonesia is less attention. Until 2004, the installed capacity of wind power utilization is only up to 0.5 MW from 9:29 GW potential. One method used to measure the wind energy potential of wind energy for electricity generation is by using the Weibull method. From the analysis that has been carried out by the method of Weibull can be concluded that the wind energy potential of wind energy for electricity generation in Banda Aceh does not meet the eligibility criteria.
