Abstract

Industri telekomunikasi berkembang sangat pesat dan perusahaan telekomunikasi terus melakukan berbagai inovasi untuk mendukung persaingan bisnis yang benar-benar sengit dan semakin sulit mendapatkan pelanggan. Persaingan ini menghasilkan churn pelanggan. Churn pelanggan yang tinggi adalah salah satu tingkat kegagalan perusahaan, oleh karena itu churn harus dikurangi. Algoritma Random Forest dipilih karena memiliki kemampuan untuk mengklasifikasikan data yang tidak lengkap dan dapat menangani data sampel yang besar. Tujuan khusus dari penelitian ini adalah untuk membandingkan kinerja algoritma Random Forest dengan optimasi menggunakan teknik boosting (XGBoost dan AdaBoost). Pada penelitian menggunakan Upsampled untuk mengatasi data yang tidak seimbang dan metode interquartile range dalam mengatasi pencilan. Hasil penelitian ini menujjukkan bahwa optimasi algoritma Random Forest menggunakan boosting AdaBoost menghasilkan kinerja yang paling optimal dengan hasil akurasi (99.13%), presisi (98.31%), recall (100%) dan f1-score (99.15%).

Abstract

Banyak kasus kematian akibat kanker disebabkan oleh pasien yang terlambat memeriksakan diri. Pasien memeriksakan diri ke dokter jika kankernya sudah pada stadium tinggi (akut). Kanker merupakan penyebab kematian utama di dunia. Pada tahun 2020, tercatat hampir 10 juta kematian akibat kanker. Pembelajaran mesin adalah teknik yang meniru cara mesin (komputer) belajar dari data. Klasifikasi merupakan algoritma pembelajaran mesin untuk mencari pola dengan tujuan memisahkan kelas data. Salah satu algoritma klasifikasi untuk mengklasifikasikan data kanker adalah algoritma support vector machine (SVM).. Pada penelitian ini kanker (tiroid, paru-paru dan usus besar) akan diklasifikasi menggunakan algoritma SVM. Pasien nantinya akan diklasifikasikan menderita kanker tiroid, kanker paru-paru, atau kanker usus besar. Dataset ini merupakan data teks yang merupakan dataset publik yang diambil dari Kaggle. Setelah data melalui preprocessing dan dilakukan klasifikasi menggunakan algoritma SVM dengan proporsi pembagian train-test sebesar 70% sebagai data latih dan 30% sebagai data uji. Hasil penelitian manunjukkan bahwa matriks kinerja algoritma sebagai berikut: nilai akurasi sebesar 93,83%, nilai presisi sebesar 94,23%, nilai recall sebesar 94,35%, dan nilai F1-measure sebesar 94,27%

Abstract

This study addresses the educational challenges faced by slow learner students, who exhibit lower cognitive abilities than their peers, particularly in the context of reading difficulties during elementary school. Recognizing the need for targeted interventions, this research focuses on the development of a culture-based digital sandpaper letter learning medium tailored to enhance the letter recognition and writing skills of slow learner students. The research employs a 4D development model, encompassing define, design, development, and dissemination phases. The sandpaper letters, featuring rough textures, serve as a sensory-motor stimulus to facilitate the learning process for slow learner students. Culturally relevant themes from Indonesia, such as dances, songs, musical instruments, names of weapons, tribes, food, and place names, are incorporated into the design to enhance engagement and connection with the material. Expert assessment sheets and teacher response questionnaires are utilized as assessment instruments. Results indicate that the developed learning medium is validated by experts and deemed practical by teachers. Furthermore, research trials demonstrate the effectiveness of the culture-based digital sandpaper letters in facilitating letter recognition and writing skills among slow learner students. This innovative approach not only addresses the specific needs of this student population but also contributes to the broader field of inclusive education.

Abstract

Corona Virus Disease (Covid-19) began to enter Indonesia in March 2020. The spread of this virus was massive in July with the highest case on July 15, 2021. So far, cases have started to decline because the discipline of health protocols has begun to be applied, and most Indonesians have received the Covid-19 vaccine. The growth of Covid-19 had a major impact and became an obstacle to Indonesia's economic growth, especially the Micro and Small Industry (MSI). According to the Asian Development Bank (ADB) there are 50% of Small and Medium Industries went bankrupt due to Covid-19 because turnover has decreased by 40% - 70%. In the Covid-19 pandemic situation, Product Branding can be offered to MSI as one of the solutions to problems to achieve economic resilience. The Community Partnership Program is expected to be able to contribute to solving the problems faced by IMK in Sorong, namely "competitor constraints" and "marketing constraints". In relation to competitor constraints and marketing constraints, MSI is expected to be able to market products easily and be able to compete. For this reason, product branding insight is needed. In this case, MSI actors need to be equipped with product branding insights, so that they can sell their products easily, precisely in booking, easy to recognize their products, and customer loyalty. For this reason, product branding skills need to be socialized to improve the quality of MSI Actors' Human Resources. Based on evaluation results, in general the initial knowledge related to product branding is good, with the lowest score for the pretest 54 and the highest score being 70. Meanwhile, in the posttest score there was a significant increase in the value, with the lowest score being 73 and the highest score reaching 95.

Abstract

Implementing learning on mathematics material that does not provide facilities for students to explore critical thinking skills results in a lack of student learning outcomes. The teacher-centred learning process makes many students passive when learning takes place, and low student learning outcomes and critical thinking are also caused by the use of less varied learning models. This makes researchers apply an approach with PMRI (Pendidikan Matematika Realistik Indonesia or Indonesian Realistic Mathematics Education). This study aimed to determine the effectiveness of PMRI in improving fourth-grade students' learning outcomes and critical thinking. This research was a pre-experimental study; the subjects in this study were fourth-grade students with 20 students. The design in this study is quasi-experimental with the form of one group pretest-posttest design. Data collection was carried out using test, observation and documentation techniques. Data analysis techniques were carried out by Normality Test, Homogeneity Test, and Paired t-test. The results showed that PMRI learning can improve students' learning outcomes and critical thinking. This is evidenced by the average value of learning outcomes pretest (69.65) and post-test (87.35). Then the average value of critical thinking at the first meeting (68.05) and the second meeting (78.85). The conclusion that can be drawn is that students' learning outcomes and critical thinking have increased after PMRI was applied to fourth-grade students.
