Abstract

This research is based on the student’ learning outcome of building construction major which is relatively low at under minimum passing grade score 75. Students are toward to be silent, passive, and less in involving on learning process. By NTH learning including the cooperative activity, it is expected to be meaningful learning providing the worthy academic experience for students, and they can possess the active involvement in learning activity. The aim is to discover the learning outcome of students after applied the cooperative learning model using NTH type. The research employs the descriptive method in which the quantitative data is number or score obtained from student’s learning outcome. The research schedule started between September 2016 and October 2016 conducted in SMK-N 1 Palangka Raya. Students of Class X TKBB SMK-N 1 Palangka Raya is selected as research subject participated by 25 person using research instrument on student’s final learning outcome. Each equation in final test sheet is investigated to gain the valid test model by three figures consisting to two lecturer of Department of Building Engineering in University of Palangka Raya and a teacher of Class X TKBB SMK-N 1 Palangka Raya. Previously it is 60 equations of test sheet. The result of validity analysis by ratter, it is obtained at about 40 valid equations. The data analysis utilized the individual and classical passing grade. The research result depicted that the whole learning activity and student’s learning outcome has been complete from 1th to 8th meeting in which it experienced the downward and upward trend. On the first meeting to last meeting, the result has been collected at 60%, 58%, 77%, 78%, 81% for complete learning portion followed by 75%, 75%, 79%, 80,9%, 83,3% categorizing into passing grade status. Then these have been compared to the final test analysis that gained the passing grade result of student’s learning outcome at around 88 % and the achievement level at 76,1 % with complete status. In conclusion, the learning outcome level can be improved by implementing the cooperative learning model with NTH type on material of specification and concrete characteristic, ceramic, and roof-tile for building construction in Class X TKBB SMK-N 1 Palangka Raya at academic year 2016/2017.

Abstract

Coconut shell is an organic waste (waste processing) of household or industrial use of coconut as the main raw material. Most usage of coconut shell is merely as a firewood which is a challenge to be able to take advantage of coconut shell optimally, when coconut shells can be proved technically as material / aggregate for concrete. It is expected to reduce the impact of environmental pollution then having alternative economic value for community. The study aims to determine what the optimum compressive strength of concrete resulting from the addition of coconut shell in the concrete mix. In this study, the coconut shell is broken down into fragments that are up to 20 mm used as an addition to the coarse aggregate mixed with fine aggregate, water and PPC cement type I of coarse sand brands. Percentage variation coconut shell applied in this study were 0%, 5%, 10%, 15% and 20%. Concrete mix design was using SNI 03-2834-2000. The test used a cylindrical specimen with a height of 30 cm, 15cm diameter with a sample of 10 cylinders for each variation of the addition of coconut shell, thus the total of 50 cylindrical specimen. Tests carried out at 14 and 28 days in the Laboratory of Building Engineering Study Program of the Faculty of Education University of Palangkaraya. The results showed the highest compressive strength of concrete that uses a mixture of 5% coconut shell in the amount of 23.66 MPa, while the compressive strength of normal concrete was resulting in the addition of 23.63 MPa compressive strength of concrete of 0.12% of normal concrete. The compressive strength of concrete on the coconut shell mixture of 10% was amounting to 19.72 MPa with a decrease of 16.54% of the compressive strength of normal concrete, shells 15% ie a decrease of 12.11 MPa to 48.75% of the compressive strength of normal concrete, shells 20% and amounting to 12.51 MPa to 47.05 decline of normal compressive strength of concrete with compressive strength forecast 28 days. The addition of coconut shell was opposite to the concrete mix increasing the strength of concrete for the addition of 5% by weight of coconut shell coconut. Shell addition of coarse aggregate in excess (over 5%) was causing the compressive strength of concrete will decrease.

Abstract

This study aims to find out how much the Effectiveness of E-Learning in the Pandemic Period in the Automotive Engineering Basic Work Subject. This study uses the research method used in this study is a qualitative descriptive research method. The subject of this study is the effectiveness of e-learning in the Automotive Engineering Basic Work subject using the online media Zoom Meeting during the Covid-19 pandemic by class X students. Automotive in the odd semester of the 2021/2022 school year. The object of research in this study were Deputy Head As if, Supporting Teachers for Basic Automotive Engineering subjects and Shiva class X. Data collection used Interview and Documentation methods. The collected data is then analyzed as a result of the research. The results of the study show that e-learning uses online media during the Covid-19 pandemic in the field of basic automotive engineering, class X students of SMKN 1 Kuala Kurun in the 2021/2022 academic year online during the Covid-19 pandemic using zoom meeting media is quite effective, but still not optimal and less efficient. This is caused by repeated boredom so that it reaches a saturation point. In addition, the material that students are able to absorb is less than half, coupled with the ability of teachers and students to use the internet which is still low. Thus online learning is felt to be quite effective when it is only done intermittently, not continuously for 1 semester.
