Get PDFThis study aims to develop folktale comic teaching materials based on Problem-Based Learning (PBL) using Adobe Illustrator to enhance cognitive learning outcomes in Indonesian language learning for 2nd-grade elementary school students. The research method used is Research and Development (R&D) with the ADDIE model. The research subjects consist of teachers and students of Grade 2 at SDN Transpangkalan. Data collection was conducted through needs analysis, observation, interviews, and cognitive learning outcome tests, with data analysis performed qualitatively and quantitatively. The research results show that the development of teaching materials was systematically carried out based on curriculum analysis and student needs. Validation results indicated an increase in feasibility: the content aspect improved from 0.50 (moderate) to 0.90 (highly valid), the language aspect from 0.57 (moderate) to 1.00 (highly valid), and the design aspect from 0.50 (moderate) to 0.87 (highly valid). Teacher and student responses also indicated that the teaching material is engaging and suitable for use in learning. The effectiveness of this teaching material was proven by an N-Gain increase in the experimental class of 0.47 (moderate category) compared to the control class, which only increased by 0.22 (low category). The Independent t-Test showed a significance value of 0.000 (p < 0.05), indicating a significant difference in student learning outcomes. Thus, the folktale comic-based PBL teaching material positively contributes to improving students' cognitive learning outcomes in 2nd-grade elementary school Indonesian language learning.This study aims to develop folktale comic teaching materials based on Problem-Based Learning (PBL) using Adobe Illustrator to enhance cognitive learning outcomes in Indonesian language learning for 2nd-grade elementary school students.

Forecasting Indonesia's Non-Oil and Gas Exports Using the Exchange Rate as an Exogenous Variable with the ARIMAX Model: Peramalan Ekspor Nonmigas Indonesia Menggunakan Variabel Eksogen Nilai Kurs Dengan Model Arimax
No full textThis study aims to develop an ARIMAX model for forecasting Indonesia’s non-oil and gas export values for the period of March to June 2025. The variables used include Indonesia’s non-oil and gas exports (Z) and the exchange rate (X), obtained from the Ministry of Trade and Bank Indonesia. The export data is monthly time series data characterized by autocorrelation. The forecasting method employed is the Autoregressive Integrated Moving Average with Exogenous Variables (ARIMAX), which extends the ARIMA model by incorporating external predictor variables. The results show that the ARIMAX(0,1,1) model is the most suitable for forecasting, yielding a Mean Absolute Percentage Error (MAPE) of 5.01%. Using the Maximum Likelihood Estimation (MLE) method, the derived model is Ẑₜ = Zₜ₋₁ - 0.4153εₜ₋₁ - 0.00000608Xₜ. The forecast indicates that Indonesia’s non-oil and gas exports will reach USD 23,692.17 million in June, with the lowest projected value in April at USD 23,003.46 million

KOMPARASI SARANA. PRASARANA, TATA RUANG DAN AKSESIBILITAS DINAS PERPUSTAKAAN DAN KEARSIPAN DAERAH JAWA BARAT DAN DINAS ARSIP PERPUSTAKAAN KOTA BANDUNG
Get PDFResearch regarding comparisons of facilities, infrastructure, spatial planning and accessibility is also important as evaluation and reference material for improving library services in the future. Library facilities and infrastructure are the main aspects that determine the comfort and completeness of the services that can be provided to visitors. First, there are significant differences between the facilities and infrastructure available in the two library objects. The Bandung City Library has more facilities such as multimedia rooms and meeting halls, while the West Java Library focuses more on book collections and reading rooms. This difference certainly affects the activities that can be carried out in the library. Second, in terms of spatial layout, the two library objects have different designs. The Bandung City Library has a modern and open design with lots of windows and natural lighting, while the West Java Library still has traditional elements with the use of thick walls and artificial lighting. This also affects visitor comfort and the learning atmosphere in the library. Third, accessibility is also an important factor in choosing a library. The Bandung City Library is more easily accessible because it is located in the city center and can be reached by public transportation, while the West Java Library is located in a suburban area. This can influence the number of visitors and community participation in library activities. The method used in this research is a qualitative method. The qualitative research method is a research method used to examine the natural state of objects, where the researcher is the main tool, data collection techniques are carried out through cross-examination, data analysis is inductive and the results of qualitative research emphasize significance rather than generalization.Penelitian mengenai komparasi sarana, prasarana, tata ruang, dan aksesibilitas ini juga penting dilakukan sebagai bahan evaluasi dan acuan untuk perbaikan layanan perpustakaan di masa mendatang. Sarana dan prasarana perpustakaan menjadi aspek utama yang menentukan kenyamanan dan kelengkapan layanan yang dapat diberikan kepada pengunjung. Pertama, terdapat perbedaan signifikan antara sarana dan prasarana yang tersedia di kedua objek perpustakaan. Perpustakaan Kota Bandung memiliki lebih banyak fasilitas seperti ruangan multimedia dan aula pertemuan, sedangkan Perpustakaan Jawa Barat lebih fokus pada koleksi buku dan ruangan baca. Perbedaan ini tentunya mempengaruhi kegiatan yang dapat dilakukan di perpustakaan tersebut. Kedua, dari segi tata ruang, kedua objek perpustakaan memiliki desain yang berbeda. Perpustakaan Kota Bandung memiliki desain modern dan terbuka dengan banyak jendela dan pencahayaan alami, sedangkan Perpustakaan Jawa Barat masih memiliki unsur tradisional dengan penggunaan dinding tebal dan pencahayaan buatan. Hal ini juga mempengaruhi kenyamanan pengunjung dan suasana belajar di perpustakaan. Ketiga, aksesibilitas juga menjadi faktor penting dalam memilih perpustakaan. Perpustakaan Kota Bandung lebih mudah diakses karena terletak di pusat kota dan dapat dijangkau dengan transportasi umum, sedangkan Perpustakaan Jawa Barat terletak di daerah pinggiran, Ini dapat mempengaruhi jumlah pengunjung dan partisipasi masyarakat dalam kegiatan perpustakaan Metode yang digunakan dalam penelitian ini adalah metode kualitatif. Metode penelitian kualitatif adalah metode penelitian yang digunakan untuk meneliti keadaan alamiah objek, dimana peneliti sebagai alat utamanya, teknik pengumpulan data dilakukan melalui pemeriksaan silang, analisis data bersifat induktif dan hasil penelitian kualitatif menekankan signifikansi daripada generalisasi
