The Effectiveness of Using Snakes and Ladders Game Mathematical Concepts (ULTAKOM) For Children Age 5-6 Years Fatrica Syafri, Fatrima Santri Syafri, Anna Zuniasari IAIN Bengkulu Abstract Creative ways to increase children^s attention, motivation, involvement and are considered to be able to help the learning process of children in the classroom so that it supports the introduction of mathematical concepts for children aged 5-6 years is an active learning technique. An active learning process cannot be separated from learning media such as the snake and ladder game of mathematical concepts. So this study aims to see the effectiveness of the use of snakes and ladders game in the introduction of mathematical concepts for children aged 5-6 years. This type of research is quantitative research. This research method is an experiment with the form of research used is a pretend experiment (Quasi experimental design). This study uses a nonquivalent control group design experimental design, namely posttest-only control group design (POCGD) for sample collection using purposive sampling technique. The study was conducted at the Misbahul Ummi Early Childhood School with a total of 44 children with a sample of 16 children consisting of 2 classes containing children aged 5-6 years. Where class B1 is the experimental class and class B2 is the control class. The results of the questionnaire on the effectiveness of early childhood on the game of snakes and ladders mathematical concepts (Ultakom) in the experimental class obtained an average value of 78.57. While the control class obtained an average score of 69.19. So that the use of the snake and ladder game in the introduction of mathematical concepts in children aged 5-6 years can be said to be ^Effective^ can be seen from table 3. the effectiveness criteria that the experimental class obtains an average value of >71% with the criteria ^Effective^ and if seen in the table 2. The criteria for the success of children with an average value of >71% in the experimental class are included in the ^Developing According to Expectations^ criteria.

INCREASING THE STUDENTS^ UNDERSTANDING OF ANALYZING DATA THROUGH PROJECT-BASED LEARNING Nurul Astuty Yensy. B (1*) Sudarwan Danim (2) Agus Susanta (3) Bengkulu University Abstract Statistics is a universal language in the modern association of the international community and as one of the main indicators of a nation^s civilization. Because statistics are related to sample data, it is necessary to have the ability to interpret, understand and make good decisions on the data. However, most of the students still have difficulty in interpreting and analyzing the data, such as difficulty in choosing the right data processing technique that is relevant to the type of data, as well as errors in interpreting the results. The learning process that is suitable for overcoming the problems like this is project-based learning. The research that examines project-based learning has never discussed how to improve students^ understanding of analyzing data, so this study wants to show that project-based learning can improve students^ understanding of analyzing data. Data were collected through observations, questionnaires, project report documents, and tests given to seventy students taking statistics courses. The results of observations in class showed that the students were very active in discussing, more skilled at communicating, very collaborative, and able to think critically in finding solutions. The results of the questionnaire showed that their learning motivation was high, most of the students agreed with this learning because it was very interesting, fun, and full of challenges. Reports on student project results show that they have performed well in analyzing data, namely understanding the types of data, selecting the appropriate statistical analysis, data processing procedures, and concluding. The students^ test scores also increased. Keywords: Project-Based Learning, Data Analysis. Share Link | Plain Format | Corresponding Author (Nurul Astuty Yensy)

Combination of Fenton Mechanism and Electrocoagulation Technology for Treatment Palm Oil Mill Effluent (POME) Diana Novita Sari (a*), Dea Amelia (b), Muhammad David Ramadhon (c), Yuant Tiandho (d) Department of Physics, Faculty of Enginering, Universitas Bangka Belitung, Indonesia Abstract Indonesia is the largest palm oil producer in the world. In proportion to the increase in production, the waste generated also increases. The palm oil mill effluent (POME) has relatively high COD and BOD so that if it is just thrown away it will cause environmental pollution. The Fenton process is one of the most effective methods in removing COD and BOD, but because Fenton utilizes ferrous ion reagents, the wastewater after the Fenton process contains quite high iron heavy metals. Therefore, it is necessary to carry out further research on the processing of POME from the Fenton process which is then combined with electrocoagulation techniques. Fenton^s research process begins with finding the optimal dose of process reagent, which is 1 liter of wastewater, 10 ml of H2O2 and 1.25 grams of FeSO4. Furthermore, the study continued with the electrocoagulation process using a time variation of 10, 20, and 30 minutes with a voltage of 20 volts. The results showed that all treatments had met the quality standards of palm oil waste with the best results obtained for Fe metal of 89.21%, COD of 99.95% and BOD of 99.96%.

Mechanical Properties Effects of Clay Ceramics by Mixing With Activated Charcoal, Rice Husk Ash, and Sugarcane Leaf Ash Muchammad Chusnan Aprianto (a*) a) Department of Mechanical Engineering, Sekolah Tinggi Teknologi Dr. KH. EZ Muttaqien Jl. Baru, Ciwareng, Kec. Babakancikao, Kabupaten Purwakarta, Jawa Barat 41151 Abstract This experimental study aims to determine the effect of mixing rice husk ash, sugarcane leaf ash, and activated carbon on the mechanical properties of ceramics. Rice husks were obtained from the rice mill in Sawah Kulon Village, Pasawahan District, Purwakarta Regency. Sugarcane leaves were obtained from the Sugarcane Plantation, Purwadadi District, Subang Regency. While activated carbon were made of burning coconut shells. Rice husk ash, sugarcane leaf ash, and activated carbon powder were mixed with clay in a ratio of 25%, 50%, and 70% in volume percent. Each sample was burned at a temperature of 300oC - 350oC for 3.5 hours. Futhermore, the pressure test and bending test were carried out to determine the mechanical properties of the sample. The results shows that there is an effect of mixing the three materials on the hardness and flexibility of ceramics.

Fast forward of adiabatic quantum transport Iwan Setiawan, Andik Purwanto, Ryan Sugihakim, Bobby Eka Gunara Physics Education Department University of Bengkulu Physics Department Bandung Institute of Technology Abstract We study a scheme of accelerated adiabatic quantum dynamics. This scheme was originally proposed by Masuda-Nakamura. The strategy of combining two opposite idea: infinitely-large timemagnification factor and infinitely-small growth rate (&#1013-) of adiabatic parameter was elucidated. We apply the proposed method to the system with electric and magnetic field and obtain regularization term, driving potential VF F and driving Hamiltonian HF F to accelerate the system. The driving potential VF F and the driving Hamiltonian HF F to be able to accelerate adiabatic transport of electron in the ground state trapped in the plane xy and electric field in the x direction and a constant magnetic field in y direction.

Analysis of Interactive Teaching Material Development Needs in the Form of Modules Android using the STEM approach Menza Hendri, Dian Pertiwi Rasmi, Nadia Yensi Febriana Jambi University Abstract This study aims to analyze the teacher^s needs for one of the development of learning media in the form of STEM-based modules that are loaded in the form of an android application. The development uses the ADDIE (Analysis, Design, Development, Implementation, Evaluation) model. The data was obtained through interview questions posed to the teacher. From the results of interviews conducted, it was found that teachers need interactive learning media that can attract students, while students need media that can make it easier for students to understand the material. So that researchers will develop modules in the form of android applications which are STEM integration.
