Abstract

This study aims to determine the effect of the Project Based Learning (PjBL) learning model on students' creative thinking skills on environmental pollution material. This type of research uses Quasi Experimental Design. The population of this study were all grade X students at MA Mu'allimat NWDI Pancor. The sample of this study was determined by Simple Random Sampling technique. Class X B as an experimental class using the Project Based Learning (PjBL) model and class X A as a control class using the lecture method. The research design used is Posttest-Only Control design which has been modified on the posttest value which is not obtained from student test scores after learning, but student creative thinking after learning. Data collection techniques used documentation, LKPD, and flower vase creativity assessment sheets. Data were analyzed using independent t-test analysis. The hypothesis results show that tcount> ttable, namely (2.795> 1.161) which means H0 is rejected and Ha is accepted, so it can be concluded that there is an effect of the Project Based Learning (PjBL) learning model on the Creative Thinking Ability of Class X MA Mu'allimat NWDI Pancor Students.

Abstract

Research conducted at SMPN 1 Suela aims to determine the effect of Discovery learning models on student learning outcomes in Biology subjects in class VIII SMPN 1 Suela Kec. Suela The research design used was quasi-experiment using pre-test and post-test of control class and experimental class. The study population was 171 students, while the sample for the control class was 25 students and the experiment was 25 students. Data about learning outcomes in Biology subjects is collected by multiple choice tests. Data analysis using t-test statistics. The results showed that there was a significant influence using Discovery learning models. Discovery learning model of the experimental class at the time of pre-test average value of 65.28 and post-test average value of 79.04 while the control class that uses conventional learning models at the time of pre-test average value of 65.12 and the average value of post test average of 72. And based on calculations using the t-test obtained t count (6.76) is greater than t table with a significant level of 5%. with degrees of freedom (dk) n_1 + n_2-2 = 25 + 25 = 48, obtained t table of 2.0126. This shows that t_ (count˃) t_table is 6.76 ˃ 2.0126. From these results it shows that Ha is accepted, meaning that there is a significant influence by using the Discovery learning model on student learning outcomes in Biology subject class VIII at SMPN 1 Suela Academic Year 2019.

Abstract

This study aims to: (1) Develop Problem-Based Learning (PBL)-based Poster Learning Media to Improve Student Learning Outcomes, (2) Determine the feasibility and validity of Problem-Based Learning (PBL)-based Poster Learning Media to Improve Student Learning Outcomes, (3) To determine the effectiveness of Poster-Based Learning Media Using Problem-Based Learning (PBL) in Improving Student Learning Outcomes. This development study employs the 4D model, which consists of four stages: Define, Design, Development, and Dissemination. The subjects of this study were subject matter experts, media experts, science teachers, and 20 students from MTs NW Sukamulia. Data collection techniques used questionnaires and tests that had previously undergone validity tests, reliability tests, difficulty level tests, and discrimination power tests. Based on the data analysis and discussion, the product is deemed suitable and valid for use in teaching and learning activities. This suitability is evident from the average suitability scores obtained: subject matter experts 3.6, media experts 3.6, science teachers 3.2, and student responses 3.6. These scores meet the criteria for good and very good. Furthermore, the validity of the poster learning media can be seen from the percentage of ideality from subject matter experts (90%), media experts (91%), science teachers (79%), and student responses (90%). Based on the percentage of ideality, the results obtained meet the criteria for valid and highly valid. Based on the average percentage for improving student learning outcomes, it falls into the very good category.

Abstract

This study aims to analyze the effect of learning media in form of posters on students’ motivation and learning outcomes in biology subjects at MA NW Sukamulia. The study was conducted with a quasi-experimental design, involving two classes: experimental class XI A which used poster media and control class XI B which applied conventional methods. Data were collected through questionnaires and learning outcome tests. The results show that students’ learning motivation in the experimental class, with an average questionnaire score of 81.4 and a standard deviation of 3.82, is higher than the control class which obtained and average score of 68 with a standard deviation of 6.47. independent T-test showed T count 7.9970, greater than T table 2.0227, indication a significant increase in students’ learning motivation using poster media. In terms of learning outcomes, the average pre-test score of the experimental class is 35.25 with an increase in the post-test to 46, while the control class shows a pre-test score of 29.52 and a post-test of 32.14. independent T-test for learning outcomes revealed T count 2.3136, higher than T table 2.0210, indicating a significant increase in the learning outcomes of students in the experimental class. Overall, the use of poster media significantly increased students’ motivation and learning outcomes in the experimental class compared to the control class.

Abstract

Kangkung darat (IpomeareptansPoir) merupakan salah satutanaman sayur yang banyak disukai oleh semua kalangan masyarakat. Kangkung darat termasuk dalam family Convolvulaceae atau kangkung-kangkungan yang dicirikan dengan batang bergetah dan berlubang di dalamnya. Penelitian ini dilakukan pada bulan juni sampai dengan November 2020 di kebun percobaan biologi universitas hamzanwadi. Rancangan yang digunakan pada penelitian ini yaitu rancangan acak lengkap (RAL) dengan 4 perlakuan dan 10 kali pengulangan sehingga didapatkan 40 satuan percobaan. Variable bebas dari penelitian ini yaitu 20 ml, 40, dan 60 ml. variable terikat dalam penelitian ini adalah pertumbuhan tanaman kangkung darat yang meliputi tinggi tanaman, jumlah daun dan panjang daun. Data yang diperoleh di uji normalitas dan homogenitasnya, bila hasilnya normal dan homogen maka kemudian dianalisis denganan analisis variansi. Hasil penelitian menunjukkan bahwa pemberian pupuk hijau tidak berpengaruh terhadap pertumbuhan tanaman kangkung darat baik tinggi, jumlahdaun, dan panjang daun.Kata kunci: pupuk hijau, pertumbuhan tanaman kangkung darat
