Eksplorasi Sentimen Pengguna pada Aplikasi E-Commerce dengan Deep Learning
Full text linkThis study investigates user sentiment toward leading Indonesian e‑commerce applications through deep‑learning‑based text classification. A balanced corpus of 50,000 Indonesian‑language reviews was collected from Google Play and App Store for Tokopedia, Shopee, Bukalapak, Lazada, and Blibli. We applied two state‑of‑the‑art approaches—Long Short‑Term Memory (LSTM) networks enriched with pre‑trained FastText embeddings and fine‑tuned Bidirectional Encoder Representations from Transformers (BERT; IndoBERT v2). Data pre‑processing included text cleaning, slang normalization, stemming, and tokenization following the KBBI standard. Both models were trained with an 80:20 stratified split and evaluated using accuracy, precision, recall, F1‑score, and AUC. BERT achieved 90.6 % accuracy and 90.1 % F1‑score, outperforming LSTM's 83.2 % accuracy and 82.7 % F1‑score. McNemar’s test indicated the improvement is statistically significant (p < 0.01). These findings show that contextual embeddings capture nuanced Indonesian sentiments more effectively than sequential RNN‑based approaches, offering actionable insights for e‑commerce stakeholders to enhance customer experience.Penelitian ini menganalisis sentimen pengguna terhadap aplikasi e‑commerce terkemuka di Indonesia melalui klasifikasi teks berbasis pembelajaran mendalam. Sebanyak 50.000 ulasan berbahasa Indonesia dikumpulkan secara berimbang dari Google Play dan App Store untuk Tokopedia, Shopee, Bukalapak, Lazada, dan Blibli.

FORMULASI DAN EVALUASI STABILITAS EKSTRAK DAUN SUNGKAI (Peronema canescens Jack) DENGAN Na-CMC
Full text linkKesehatan gigi dan mulut merupakan bagian penting dari kesehatan secara keseluruhan, namun karies gigi masih menjadi penyakit yang umum diderita oleh masyarakat. Plak gigi adalah penyebab utama masalah kesehatan gigi dan mulut dan pasta gigi berperan penting dalam mengendalikannya. Daun sungkai (Peronema canescens Jack) memiliki berbagai khasiat, termasuk sifat antibakteri. Penelitian ini bertujuan untuk memformulasikan dan mengevaluasi stabilitas pasta gigi yang mengandung ekstrak daun sungkai dengan menggunakan Na-CMC sebagai agen pengikat. Ekstrak daun sungkai dibuat melalui maserasi dengan etanol 96%. Empat formula pasta gigi, termasuk satu kontrol, dibuat dan diuji stabilitas fisiknya (uji homogenitas, pH, tinggi busa, dan organoleptik) selama dua minggu. Hasil pengujian menunjukkan bahwa semua formula homogen dan memiliki pH yang stabil dalam rentang 6,5 hingga 8,0, yang sesuai dengan standar SNI (4,5-10,5). Namun, tidak ada busa yang signifikan yang terbentuk, kemungkinan karena viskositas yang tinggi akibat konsentrasi Na-CMC yang berlebihan. Formula 3, dengan konsentrasi Na-CMC tertinggi, menunjukkan tekstur paling kental dan stabil. Disimpulkan bahwa formulasi pasta gigi ekstrak daun sungkai berhasil dibuat dengan stabil, dan formula 3 adalah yang paling ideal, meskipun busa tidak terbentuk.
