Abstract

Pemahaman konsep fisika, terutama momentum dan impuls, merupakan hal yang penting dalam pembelajaran fisika di sekolah menengah. Namun, banyak siswa mengalami kesulitan dalam memahami konsep-konsep ini karena sifatnya yang abstrak. Penelitian ini bertujuan untuk menguji pengaruh PHET Simulation dalam meningkatkan pemahaman konsep fisika pada materi momentum dan impuls, dibandingkan dengan metode ceramah konvensional. Metode yang digunakan adalah eksperimen dengan desain two-group pre-test post-test design, melibatkan dua kelompok siswa kelas XI di SMAN 15 Muara Jambi. Kelompok pertama menggunakan PHET Simulation, sedangkan kelompok kedua menggunakan ceramah. Data diperoleh melalui tes pre-test dan post-test, yang dianalisis menggunakan N-Gain untuk mengukur peningkatan pemahaman. Hasil penelitian menunjukkan bahwa kelas A yang menggunakan PHET Simulation memiliki nilai N-Gain rata-rata sebesar 66,39% (cukup efektif), sedangkan kelas B yang menggunakan ceramah hanya mencapai 41,14% (kurang efektif). Kesimpulannya, PHET Simulation terbukti lebih efektif dalam meningkatkan pemahaman siswa terhadap materi momentum dan impuls dibandingkan dengan metode ceramah konvensional.

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan memberdayakan ibu-ibu PKK Medokan Ayu Timur, Rungkut, Surabaya melalui pelatihan pembuatan batik kerudung dengan teknik ikat celup dan ecoprint menggunakan pewarna alami dari limbah dapur. Permasalahan utama yang dihadapi mitra adalah belum adanya pengetahuan dan keterampilan dalam memanfaatkan bahan-bahan sisa dapur, seperti kulit kunyit, ampas kopi, ampas teh, kulit bawang merah, dan kulit bawang bombay, sebagai pewarna alami. Selain itu, mitra juga memerlukan pendampingan dalam proses pemberian merek dan pemasaran produk secara digital. Kegiatan dilaksanakan melalui pendekatan observasi dan partisipasi aktif agar peserta terlibat langsung serta mampu berlatih secara mandiri. Pelatihan terbagi menjadi dua tahap, yaitu penyampaian materi dan praktik lapangan yang berlokasi di rumah anggota mitra. Pada tahap praktik, peserta diajarkan mulai dari proses persiapan kain, pewarnaan, pengikatan, pencelupan, pembilasan, hingga pengeringan, dilanjutkan dengan sesi branding dan promosi produk melalui media sosial. Hasil kegiatan menunjukkan antusiasme peserta yang tinggi serta kemampuan mereka dalam menghasilkan motif batik yang unik dan estetis. Produk batik yang dihasilkan kemudian dikembangkan melalui pemberian merek, pengemasan, dan pameran yang didukung oleh publikasi di akun media sosial PKK Medokan Ayu Timur. Program ini didanai oleh Diktisaintek Berdampak bekerja sama dengan Institut Sains dan Teknologi Terpadu Surabaya, dan diharapkan menjadi langkah awal bagi pengembangan batik ramah lingkungan di masyarakat sekitar.

Abstract

Reptil dan amfibi merupakan dua kelompok hewan vertebrata yang memiliki peran penting dalam ekosistem, namun kerap sulit dibedakan hanya melalui pengamatan visual. Kemiripan warna kulit, bentuk tubuh, dan pola permukaan sering menimbulkan kesalahan identifikasi, terlebih ketika faktor pencahayaan, latar belakang, dan sudut pengambilan gambar bervariasi. Kondisi ini menimbulkan tantangan signifikan bagi proses identifikasi otomatis berbasis citra. Penelitian ini bertujuan mengembangkan model identifikasi berbasis citra dengan memanfaatkan algoritma Convolutional Neural Network (CNN), yang dikenal handal dalam mengekstraksi dan mempelajari fitur visual dari data citra kompleks. Dataset penelitian terdiri dari 6.045 gambar yang mencakup 10 spesies, dikategorikan menjadi dua kelas utama, yaitu reptil dan amfibi. Arsitektur CNN yang dirancang terdiri dari tiga lapisan konvolusi, pooling, dan fully connected, disertai mekanisme callback seperti EarlyStopping dan ModelCheckpoint untuk mencegah overfitting dan mempertahankan bobot terbaik. Hasil pengujian pada data uji menunjukkan akurasi 86,60%, dengan nilai F1-score 0,91 untuk kelas reptil dan 0,73 untuk kelas amfibi. Perbedaan kinerja ini menunjukkan model lebih optimal dalam mengenali reptil dibandingkan amfibi, yang kemungkinan disebabkan oleh distribusi data tidak seimbang dan kompleksitas visual pada amfibi. Secara keseluruhan, penelitian ini membuktikan bahwa CNN dapat digunakan sebagai alat bantu identifikasi otomatis yang efektif untuk membedakan spesies reptil dan amfibi berdasarkan citra visual.

Abstract

Introduction: As a first-line antiepileptic drug for partial and tonic-clonic seizures, carbamazepine requires long-term use. This drug carries a risk of Stevens-Johnson syndrome (SJS) or toxic epidermal necrolysis (TEN) reaction. Case: A 23-year-old woman with a history of seizures had reddish rashes on the face, neck, chest, back, and left and right upper extremities covering 10% of the body surface area (BSA) after taking carbamazepine 200 mg twice a day for her seizures. Discussion: The patient was given methylprednisolone 16 mg tablets twicea day, IV diphenhydramine twice a day, and other symptomatic drugs. After 9 days, the patient was discharged with phenytoin 100 mg tablets twice a day as a substitute for carbamazepine. Early treatment with high-dose systemic steroids provides benefits of rapid recovery,especially in SJS patients where skin damage is not too extensive and can be restored by the anti-inflammatory effects of steroids. The main treatment of SJS/TEN is early recognition and immediate discontinuation of the drug. Conclusion: Carbamazepine is often a risk factor forSJS, thus an alternative treatment is needed.

Abstract

Developing telecommunications infrastructure is vital for national advancement improving connectivity to accelerate information flow and access to public services Effective base station planning prioritizes maximizing network coverage in densely populated areas However traditional visualization methods often fall short in identifying regions with the highest population density This study addresses this gap by applying a sector expansion algorithm to select optimal base station locations within the most densely populated sectors achieving more balanced network coverage Using Indonesia s population data and administrative boundaries optimal base station locations are determined with DBSCAN and K Means clustering algorithms The network s reach is then enhanced through sector expansion to increase coverage in areas with high population density by selecting new base station locations based on the densest sector around a primary station The candidate station is positioned at a distance of three quarters of twice the radius of the primary station optimizing coverage while remaining close to existing network resources The evaluation compares population coverage before and after sector expansion assessing connectivity between base stations and distribution efficiency Results show that sector expansion increased population coverage on Lombok Island from 15 94 to 99 14 with the most populated base station covering up to 34 274 people enhancing distribution efficiency < p>

Abstract

One of the world's largest consumption of energy is crude oil, which is a source of transportation fuel. Crude oil is often used as an indicator of the world economy because fluctuating oil prices can affect a country's capital market, both developed and developing countries. This study aims to analyze the comparison of the effect of crude oil prices on stock indexes in Indonesia and Malaysia during the RussiaUkraine War. This research is a comparative research using saturated sampling data collection method with a total sample of 454. The data is taken from index data listed on the Indonesian and Malaysian stock exchanges and world oil price data, then the data is tested using the Statistical Program for Social Science application. (SPSS). The results of this study indicate that the price of crude oil has a significant positive effect on the stock price index of Indonesian energy companies, while for Malaysia it produces a significant negative relationship.

Abstract

Each individual has their own assets, but the important thing is how to manage them properly and correctly. A bad investment or even consumptive behavior will cause the person to experience losses and bankruptcy. Lack of knowledge and education about managing finances will be a big challenge, especially for students. This research aims to examine the effect of financial knowledge and financial attitude on the personal financial management of Batam International University students. Data was obtained by filling out questionnaires, which were distributed to 97 students at Batam International University using Google Forms as a data collection tool. The analytical method used in this study is the partial least squares structural equation model (PLS-SEM). Based on the results of the research, it can be concluded that financial knowledge and financial attitude have a significant positive effect on financial management.
