s business faces the challenge of unpredictable monthly fluctuations in consumer demand, which often lead to supply imbalances, overproduction, or lost profit opportunities due to stockouts. This study aims to implement and analyze the accuracy of the Single Moving Average (SMA) quantitative forecasting method in predicting Sate Padang Hapis sales volumes for June 2026. Model performance was evaluated by assessing mathematical accuracy across two time-interval variations: 3-month and 5-month moving averages. Projection error rates were rigorously measured using Mean Absolute Deviation (MAD), Mean Squared Error (MSE), and Mean Absolute Percentage Error (MAPE) parameters. The analysis reveals that the Single Moving Average model with a 5-month interval yields projections closest to actual data, achieving the lowest error rates (MAD: 28.00; MSE: 1,304.00; MAPE: 2.28%). Implementing this forecasting model provides management with an objective basis for decision-making, enabling the effective and efficient optimization of raw material logistics and supply management.

Abstract:Signal interference or noise is one of the main problems in data transmission that can reduce information quality in both analog and digital systems. This study aims to visually analyze the effects of noise using audio software.…
oftware. The method used is simulation-based, where a pure signal is used as an initial reference before being subjected to various levels of interference. The analysis results show that in analog signals, noise causes permanent waveform distortion that is difficult to recover. In contrast, digital signals tend to maintain data integrity as long as the interference does not exceed a certain threshold. These differences in signal characteristics can be visually observed through waveform displays in the software. The results indicate that digital systems have advantages in maintaining signal quality in noisy environments and have the potential to be used as educational media for basic telecommunication and signal processing studies.

ese issues by providing educational assistance. However, in its implementation, the selection of PIP recipients at IT Al-Ikhsan Private Junior High School is still inaccurate. This research aims to classify the eligibility of PIP recipients using the Naive Bayes method. This method is applied to student data from the school's Dapodik in 2024 which consists of 265 students. The data is processed through CRISP-DM data mining stages, namely Business Understanding, Data Understanding, Data Preparation, Modeling, Evaluation, and Deployment. As a result, the Naive Bayes model showed an accuracy of 92.31% with a precision value for the “Yes” class of 89%, recall 100%, and F1-score 94%. In conclusion, variables such as means of transportation, KPS and KIP recipients, parents' income, and distance from home to school affect the eligibility of PIP recipients.
Abstract:Diagnostic assessment tests for students entering elementary school were conducted once, focusing solely on letter reading. However, teachers did not assess syllable, word, paragraph, or reading comprehension, leading to…
ongoing issues in early reading ability among students. This study aimed to describe the early reading ability of the first-grade students at SDN 014 Tarakan through diagnostic assessment in terms of five key aspects: reading letters, reading syllables, reading words, reading paragraphs, and comprehending information from reading. A qualitative descriptive approach was employed in this study. Data were collected through interviews, observations, and documentation. The findings revealed that in the letter reading aspect, 34 out of 55 students were fluent, while 21 were not. In the syllable reading aspect, 27 students were fluent, and 28 were not. In the word reading aspect, 21 students read fluently, while 34 did not. In the paragraph reading aspect, 15 students read fluently, and 40 struggled. In the comprehension aspect, 16 students could understand the content, whereas 39 had difficulties with comprehension. The study also identified several challenges faced by students with reading difficulties. These included poor memorization of letter shapes, frequent errors such as changing, omitting, or misplacing letters, difficulty with long words, limited vocabulary, and lack of concentration while reading.
Abstract:Epilepsi anak membutuhkan tata laksana farmakologis jangka panjang yang bertujuan menurunkan frekuensi kejang dengan efek samping seminimal mungkin. Terapi antikejang tunggal umumnya dipilih sebagai strategi awal karena…
regimen lebih sederhana, evaluasi respons lebih jelas, dan risiko interaksi obat lebih rendah. Namun, sebagian anak tetap mengalami kejang meskipun telah mendapat terapi awal yang adekuat, sehingga terapi kombinasi diperlukan pada kasus tertentu. Tinjauan literatur ini bertujuan menganalisis peran terapi antikejang tunggal dan kombinasi pada epilepsi anak, khususnya terkait frekuensi kejang, keamanan, kepatuhan, dan kualitas hidup. Metode disusun menggunakan kerangka PICO dan alur seleksi berbasis PRISMA. Penelusuran literatur dilakukan melalui PubMed, ScienceDirect, Google Scholar, Cochrane Library, dan laman pedoman klinis resmi untuk publikasi tahun 2021-2026. Sebanyak 14 artikel dan dokumen pedoman memenuhi kriteria kelayakan dan disintesis secara naratif. Hasil kajian menunjukkan bahwa terapi antikejang tunggal tetap rasional sebagai pendekatan lini awal, sedangkan terapi kombinasi lebih tepat dipahami sebagai eskalasi terapi pada anak dengan kontrol kejang belum optimal. Perbedaan frekuensi kejang antara kedua kelompok terapi harus ditafsirkan dengan mempertimbangkan tipe kejang, etiologi, durasi penyakit, kepatuhan, komorbiditas, riwayat kegagalan terapi, dan derajat keparahan awal.

Teknik pengumpulan data dilakukan melalui dokumentasi teks berita dan studi pustaka. Hasil penelitian menunjukkan bahwa kedua media memiliki konstruksi realitas yang berbeda dalam membingkai isu lingkungan. Detik.com membingkai isu lingkungan sebagai persoalan krisis pengelolaan sampah yang membutuhkan intervensi kebijakan pemerintah dan perubahan perilaku masyarakat. Sementara itu, RRI membingkai isu lingkungan sebagai bagian dari perubahan gaya hidup generasi muda yang semakin sadar terhadap keberlanjutan lingkungan. Penelitian ini menunjukkan bahwa media online memiliki peran penting dalam membentuk pemaknaan publik terhadap isu lingkungan melalui pemilihan sudut pandang, narasi, dan solusi yang ditonjolkan dalam pemberitaan

nelitian ini menggunakan pendekatan kualitatif dengan metode analisis semiotika Roland Barthes dan analisis resepsi Stuart Hall. Data penelitian berupa satu unggahan Instagram yang terdiri dari 11 slide serta 200 komentar dari total 293 komentar. Hasil penelitian menunjukkan bahwa dr. Tirta merepresentasikan proses sebagai perjalanan panjang yang melibatkan perjuangan fisik, mental, dan sosial. Representasi ini dibangun melalui penggunaan data, visual penderitaan, serta validasi sosial. Namun, audiens memaknai representasi tersebut secara beragam, terbagi ke dalam dominant reading (65%), negotiated reading (20%), dan oppositional reading (15%), khususnya terkait isu privilege. Temuan ini menunjukkan adanya kontestasi makna antara narasi yang dibangun oleh kreator dan interpretasi audiens dalam media sosial.
