Abstract

The design of Ohm’s Law and Kirchoff’s Law trainers is an innovation aimed at improving the effectiveness process, particularly in the subjects of Ohm’s Law and Kirchoff’s Law. This trainer utilizes an AC-to-DC converter module and a DC-to-DC step-down module as the main power supply. The main structure of the trainer is divided into three key parts: the power supply, circuitry, and measurement tools. Ohm’s Law and Kirchoff’s Law are the focus in selecting the material, as they constitute the fundamental laws in electronics. During practical exercises, students often encounter challenges related to neatness, the structure of the materials, and practical tools. The trainer is expected to overcome these issues by providing a more structured and practical environment. By utilizing this trainer, it is expected that students can more easily comprehend and practically apply the concepts of Ohm’s Law and Kirchoff’s Law. Based on the test results, the trainer can provide measurement results that closely approximate accuracy with minimal differences from manual calculations. This indicates that the trainer will provide a consistent, practical experience in line with fundamental electronic principles. Moreover, the learning process can become more organized and efficient, improving the overall quality of learning in the basic electronic law.

Abstract

This study aims to evaluate the impact of implementing the Project-Based Learning (PjBL) model assisted by Multisim software on students' learning outcomes in the subject of planning and installation of audio-video systems (PISAV) in class XI Audio Video Engineering at SMK Negeri 1 West Sumatra. This research uses a quasi-experimental research design with a quantitative approach. The experimental design employs the One Group Pretest-Posttest Design. In this research, we conducted a pretest on one sample group before treatment (condition before), and after the treatment, we conducted a posttest (condition after). The sample in this study is the XI TAV class at SMK Negeri 1 West Sumatra. The research instruments used include pretest and posttest questions in objective form. The results of this study show that the condition after treatment has an average of 79.09, exceeding the condition before treatment, with an average of 50.18. These results suggest that the application of the PjBL learning model assisted by Multisim software has a significant impact on improving students' learning outcomes by 57.61%. Based on the hypothesis test results, it can be concluded that the t-value (21.59) is higher than the t-table (1.68), leading to the rejection of the null hypothesis (H0) and acceptance of the alternative hypothesis (H1). In conclusion, there is an improvement in students' learning outcomes in the PISAV subject after the application of the PjBL learning model assisted by Multisim software.

Abstract

Alfatih School Indonesia is the first Islamic school with a combination of Indonesia and Turkey which was founded on August 15 2019. This school always ensures that its students are safe from going to school to leaving school, but currently the school only carries out supervision by waiting and ensuring that only parents students who are allowed to pick up students. This method is less effective because there is no accurate documentation or records, besides that many crimes occur, such as kidnapping, which means that security must be improved. In this research, an Android-based school children pick-up and drop-off monitoring application was built using the WhatsApp API with the QR Code feature. The application that was built is equipped with the main feature of Whatsapp Information, namely a feature that allows parents to receive detailed information about the person who picked up their child via Whatsapp messages sent to the parents' Whatsapp number by the application automatically. The type of WhatsApp that will be used is the WhatsApp API (Application Program Interface). The message will be sent after the school confirms it using a scan of the QR Code that each parent has. To ensure security the generated QR Code will always be different and can only be created through the application. The application built can also validate invalid QR-Code

Abstract

Penelitian ini bertujuan untuk mengetahui hasil elektroreduksi CO2 menggunakan elektroda boron-doped diamond (BDD) yang didepositkan logam emas (Au). Au didepositkan pada elektroda boron-doped diamond (BDD) menggunakan teknik kronoamperometri. Berbagai konsentrasi digunakan dengan potensial deposisi secara berturut-turut -0,2 dan -0,3 V (vs Ag/AgCl). Siklik voltametri diterapkan untuk menentukan kondisi optimum elektroreduksi CO2 pada Au. CO2 dilarutkan dalam larutan NaCl 0,1 M dan Na2SO4 0,1 M. Suatu puncak reduksi yang berhubungan dengan CO2 muncul pada potensial -0,7 V (vs Ag/AgCl) pada larutan NaCl, sementara tidak ada puncak yang muncul pada larutan Na2SO4. Hasil tersebut menunjukkan bahwa modifikasi logam pada elektroda boron-doped diamond (BDD) dapat digunakan sebagai elektroda kerja pada elektroreduksi CO2.

Abstract

Tujuan penelitian ini adalah untuk menentukan model optimal pada klasifikasi sapi dan babi dengan menerapkan augmentasi data serta hyperparameter pada Convolutional Neural Network (CNN) arsitektur EfficientNet-B0. Data citra daging sapi dan daging babi yang diambil langsung dari beberapa pasar yang ada di kota Pekanbaru. Data diambil menggunakan kamera DSLR dan kamera smartphone dengan jarak antara 10cm sampai 15cm dan pencahayaan menyesuaikan dengan kondisi cahaya pada lingkungan pasar. Proses pelatihan dan pengujian model klasifikasi menggunakan beberapa skenario yaitu kombinasi pembagian data, jenis dataset, optimizer, fungsi aktivasi, dan learning rate. Berdasarkan hasil pengujian, model klasifikasi yang memiliki nilai akurasi tertinggi adalah 0,93 yaitu model dengan skenario jenis dataset gabungan (dataset original ditambah dengan dataset hasil augmentasi) dengan pembagian data 90% data latih dan 10% data uji. Hasil pengujian akurasi tertinggi menunjukkan model tidak overfitting, tetapi masih ada beberapa data citra daging sapi yang diklasifikasikan menjadi daging babi ataupun oplosan, sehingga perlu dilakukan penelitian lebih lanjut untuk meminimalkan masalah tersebut karena sebagai seorang muslim harus memastikan daging sapi yang dimakan adalah benar daging sapi.

Abstract

Masalah keterbatasan data latih menjadi tantangan utama dalam klasifikasi sentimen di berbagai bahasa, termasuk bahasa Indonesia, terutama untuk analisis sentimen terkait topik tertentu. Hal ini disebabkan oleh berbagai faktor, dan umumnya adalah kebutuhan untuk mengetahui dengan segera bagaimana sentimen terhadap suatu isu, sehingga tidak mungkin menghabiskan waktu untuk memberi label yang cukup pada data untuk proses pelatihan. Penelitian ini mengusulkan model klasifikasi sentimen dengan sumber data pelatihan yang sedikit, pada studi kasus pengangkatan Kaesang Pangarep sebagai ketua umum PSI. Algoritma Random Forest digunakan sebagai model dasar (baseline) yang dioptimasi dengan penambahan data eksternal untuk training, pemrosesan teks (text preprocessing) dan parameter tuning. Fitur input yang digunakan adalah model bahasa IndoBERT sebagai embedding kata untuk menghasilkan representasi teks yang lebih kontekstual. Hasil penelitian menunjukkan bahwa metode IndoBERT dengan Random Forest yang dioptimasi memberikan peningkatan performa yang signifikan dibandingkan baseline, sebesar 6%. Hasil klasifikasi model yang paling optimal sebesar 54% unutk F1-score dan 63% akurasi. Temuan ini menegaskan bahwa penambahan data eksternal dan optimasi parameter dapat meningkatkan kemampuan generalisasi model dalam klasifikasi sentimen bahasa Indonesia. Penelitian ini diharapkan dapat menjadi referensi metodologis bagi studi klasifikasi sentimen serupa yang menghadapi kendala ukuran dataset.

Abstract

Psychological assessment for students is one of the activities that cannot be separated from counseling services. Psychological attributes obtained from the implementation of the assessment can be used by school counselors to intervene and develop counseling programs. However, conditions in the field indicate that school counselors still have not carried out a comprehensive assessment of the condition of students, so this has an impact on the effectiveness of counseling services. This research and community service aims to provide training and skills for school counselors in conducting psychological assessments using an Android application called Potential. The urgency of using this application has increased since the emergence of the Covid-19 pandemic, where students and school counselors cannot meet face-to-face. This community service is carried out in stages in a series of workshops and independent training. School counselors are provided with a Potential account that can be used at their school. The results of community service activities show that students' psychological conditions are generally mapped through applications and assist school counselors in planning and developing effective programs.

Abstract

This study aims to investigate the potential of chalcone derivatives as antimalarial agents. The structure of the  chalcone derivatives was designed by inserting amino substituents on acetophenone and methoxy variants on benzaldehyde to  produce three amino chalcone derivatives (C1, C2, and C3). The synthesis was carried out by carrying out the Claisen-Schmidt  condensation reaction with NaOH 40% as catalyst, resulting in compound yields ranging from 66% - 83%. The structure of the  three compounds was determined by FTIR, MS, and 1H-NMR spectroscopy techniques, which confirmed that the compounds  had structures that were in line with the desired molecular structure. The antimalarial activity test was carried out by inhibiting  the heme polymerization process into hemozoin (β-hematin) using hydroxychloroquine sulfate as a positive control. Absorption  measurements were carried out at two different wavelengths, namely 415 nm and 630 nm. The results of the IC50 antimalarial  activity of the three compounds (C1, C2, C3) were obtained respectively at 227.61; 115.18; 260.01 µg/mL and positive control of  184.98 µg/mL. From these results, it was found that compound C2 showed better antimalarial activity compared to the other two  compounds and positive control.
