Abstract

The National Achievement Center (Puspresnas) and the Ministry of Education and Culture of the Republic of Indonesia proudly present the Indonesian Ash Robot Contest (KRAI), a yearly student robotics competition where teams tackle ash-related challenges with their robot creations. At KRAI 2021, it was shown that many robots were controlled using joysticks and resulted in a lack of effectiveness in robotic motion. The use of a joystick makes the movement of the robot take longer. This is because the robot is controlled by humans and the robot has not been able to pinpoint the robot's location. Gyrodometry is a method to map the robot's position using a inner ear and compass of the machine. In this research, Gyrodometry is used to map the position based on the readings of the gyroscope sensor and rotary encoder so that the robot can move automatically. In this research, the KRAI hitter robot can map positions and move in an accurate direction and can move automatically and effectively so that it can save more time and can increase the possibility of strategy in the match. From the results of this study, it was found that without using gyrodometry the error of X reached 11.825 cm and Y reached 35.1325 cm and also the angle error reached 13.7 degrees. and by using gyrodometry error X reaches 4.25 cm and Y reaches 5.775 cm and angle error 2.01 degrees. From these results, it was found that using gyrodometry was better than without using gyrodometry. The addition of waypoints to the robot only produces an average error of 8.2 cm X and Y error of -7.8 cm and the angle error reaches 10.2 degrees.

Abstract

Masalah emisi gas buang akan terus berlangsung selama manusia menggunakan bahan bakar fosil. Emisi gas buang dapat diturunkan dengan menggunakan katalis yang terbuat dari berbagai macam material, seperti aluminium, tembaga, seng, dan lainnya. Sehingga penelitian ini dilakukan untuk mengetahui pengaruh penggunaan jenis matrial katalis alumunium dan seng terhadap emisi gas buang HC dan CO. Metode yang digunakan dalam penelitian ini dengan menguji Katalitik converter menggunakan uji eksperimental menggunakan alat uji emisi dan dyno test (uji performa mesin). Dari penelitian diketahui bahwa kadar CO dan HC  terendah pada penggunaan katalis alumunium 2 saringan dengan torsi sebesar 5.69 dan power sebesar 3,9 hp. Menurunnya emisi gas buang karena katalis alumunium dan seng terbukti efektif menurukan kadar CO dan HC. The problem of exhaust emissions will continue as long as humans use fossil fuels. Exhaust gas emissions can be reduced by using catalysts made from various materials, such as aluminum, copper, zinc, and others. So this research was carried out to determine the effect of using aluminum and zinc catalyst materials on HC and Co exhaust emissions. The method used in this research is to test the catalytic converter using experimental tests using emission test equipment and dyno tests (engine performance tests). From the research, it is known that the lowest CO and HC levels are when using  2 filter aluminum catalyst with a torque of 5.69 and a power of 3.9 hp. Reduced exhaust emissions due to aluminum and zinc catalysts proven to be effective in reducing CO and HC levels.

Abstract

Kegagalan material berakibat komponen otomotif bisa menjadi patah, selain itu dapat berakibat chassis suatu kendaraan menjadi megalami lendutan (defleksi).  Faktor yang mempengaruhi kegagalan adalah beban pada suatu komponen kendaraan. Tujuan dari penelitian ini adalah untuk menganalisa tegangan dan defleksi pada engine stand sepeda motor akibat pembebanan. Engine stand menggunakan variasi ketinggian 40 cm, 45 cm dan 50 cm dengan bantuan software Autodesk Inventor Professional 2019. Hasil penelitian menunjukkan ketinggian 40 cm adalah ukuran ketinggian yang paling baik, karena tegangan normal (Smax), tegangan geser Tx, dan defleksinya minimum, walaupun pada nilai tegangan shear stress Ty nya nilainya lebih tinggi dari ukuran lainnya, tetapi nilainya sangat kecil dibandingkan Tegangan yieldnya (0,6 MPa < 207 MPa ). Hal ini berdampak positif pada rangka engine stand karena tidak terjadi deformasi plastis (rangka tidak akan patah). Material failure can cause automotive components to break, besides that it can cause a vehicle's chassis to experience deflection (deflection). Factors that affect failure is the load on a vehicle component . The purpose of this research is to analyze the stress and deflection on the motorcycle engine stand due to loading. The engine stand uses height variations of 40 cm, 45 cm and 50 cm with the help of Autodesk Inventor Professional 2019 software. The results showed that a height of 40 cm is the best measure of height, because the normal stress (Smax), shear stress Tx, and deflection are minimum, even though the shear stress value Ty is higher than the other sizes, the value is very small compared to the yield stress. (0.6 MPa < 207 MPa ). This has a positive impact on the engine stand frame because plastic deformation does not occur (the frame will not break).

Abstract

Project-based Learning is a learning model that has been proven to be effective in fostering students' active involvement in learning and developing abilities and skills. This research aims to determine the improvement in science process skills of class X students at SMA Negeri 1 Langsa through applying PjBL in biology learning. This research uses a pre-experimental approach, with a one-group pretest-posttest design involving 35 students. Data collection instruments include pretest-posttest questions and observation sheets to assess students' science process skills. Pretest-posttest data analysis was carried out using the N-gain test. In contrast, the assessment of science process skills data was analysed based on the percentage of achievement of each indicator. Research findings show a significant increase in students' science process skills, with an N-gain score of 0.76, which is in the high category. In particular, students showed excellent skills in the indicators of observing (87%), classifying (84%), formulating hypotheses (88%), conducting experiments (95%) and communicating (94%).

Abstract

Technology can be used as a preventive measure to avoid theft. One technology that can interfere and even make the perpetrator cancel the robbery is an alarm. With the sound of the alarm, the thief can be surprised and will immediately save himself because he is worried about being caught. Until now, various alarm technologies have been studied, from simple to complex. There are also many sensors used as triggers for alarm activation. This study created a simple anti-break alarm that is not easily turned off using a magnetic switch and relay. Several parameters are measured to determine the performance of the input and output of the alarm such as voltage and current, then a consistency test is carried out from the alarm that was created. The results obtained were that the alarm functioned properly. The alarm can sound when the door is opened then continues to sound and does not break when the door is closed again. The alarm also works consistently after 100 tests.

Abstract

Science process skills are skills that help students acquire and develop knowledge through direct observation of natural phenomena. SPS is important for students because it makes students more active, trains their questioning skills, and improves their understanding of subject matter through real experiences. This study aims to evaluate the effectiveness of the implementation of an integrated project-based learning nature exploration approach in improving biology SPS. This quantitative study used a pre-experimental approach with a one group pretest-posttest design. The study was conducted at SMAN 4 Langsa in May 2024 with a sample of 24 grade X students from a total population of 44 students. The research instruments used were pretest-posttest questions and SPS observation sheets. Data were analyzed using SPSS to see changes in skills before and after learning. The results showed an increase in SPS, with an average pretest score of 64.5 and a posttest of 84.8. The N-Gain obtained was 0.59, indicating a moderate increase. The average score of students' SPS> 82.3, indicating that aspects of skills such as observing, grouping, and planning experiments had increased. In conclusion, the integrated PjBL nature exploration approach effectively improves students' KPS. The implication is that this approach can be used as an effective innovative learning strategy to facilitate understanding of biological concepts and improve students' scientific skills through exploration of the surrounding environment. Abstrak. Keterampilan proses sains merupakan keterampilan yang membantu siswa memperoleh dan mengembangkan pengetahuan melalui observasi langsung fenomena alam.
