Abstract

Reading is an act that opens the door to knowledge and new information for individuals. However, the interest in reading in Indonesia has a concerning record. Indonesia ranks 60th out of 61 countries in the reading interest index. UNESCO data shows that only 0.001% of Indonesia's population actively reads. Factors such as the lack of school libraries, limited budgets, and the impact of technology have contributed to the low reading interest, especially among students. The LINE Program is an initiative by the UNM 2023 KKNT team aimed at increasing the reading interest of elementary school children in Jompie Village. This program uses participatory observation methods to understand children's interaction with books and literacy. The LINE program has successfully achieved positive results. Children's reading interest has increased, they have developed reading skills, taken the initiative to read independently, expanded their vocabulary, and gained a deeper understanding. This program also promotes lifelong learning. The LINE program has transformed children into diligent and initiative readers, providing long-term benefits in their literacy and education development. In efforts to increase reading interest in Indonesia, initiatives like this are crucial to be implemented nationwide. Abstrak Membaca merupakan tindakan yang membuka pintu pengetahuan dan informasi baru bagi individu. Namun, minat membaca di Indonesia memiliki catatan yang mengkhawatirkan. Indonesia menduduki peringkat ke-60 dari 61 negara dalam indeks minat membaca. Data UNESCO menunjukkan bahwa hanya 0,001% dari penduduk Indonesia yang aktif membaca. Faktor-faktor seperti kurangnya perpustakaan sekolah, anggaran terbatas, dan dampak teknologi telah berkontribusi pada rendahnya minat baca, terutama di kalangan siswa. Program LINE adalah inisiatif tim KKNT UNM 2023 yang bertujuan untuk meningkatkan minat baca anak-anak sekolah dasar di Desa Jompie. Program ini menggunakan metode observasi partisipatif untuk memahami interaksi anak-anak dengan buku dan literasi. Program LINE telah berhasil mencapai hasil positif. Minat baca anak-anak telah meningkat, mereka telah mengembangkan keterampilan membaca, mengambil inisiatif membaca mandiri, meningkatkan kosakata, dan mendapatkan pemahaman yang lebih mendalam. Program ini juga mendorong pembelajaran seumur hidup. Program LINE telah mengubah anak-anak menjadi pembaca rajin dan inisiatif, memberikan manfaat jangka panjang dalam perkembangan literasi dan pendidikan mereka.

Abstract

This research is applied research to determine the numerical solution for the SIPAS mathematical model for the spread of monkey business practices using the Adams-Bashforth-Moulton method. The epidemic model for the spread of monkey business practices is susceptible, infected, practiced, and awareness (SIPAS). The discussion begins by determining the initial solution using the fifth order Runge-Kutta method, prediction and correction values using the Adams-Bashforth-Moulton method, simulation and analysis of the results. In this research, it was found that the Adams-Bashforth- Moulton method predicts an increase in the population who know a viral business and become vulnerable(S) due to the number of residents who know a viral business and the population who are aware of the dangers of monkey business practices. Meanwhile, the population that is interested (I), practiced (P) and awareness (A), on the other hand, has decreased and disappeared completely due to a population that has stopped following a viral business and is aware of the dangers of monkey business practices. After carrying out simulations and analyzing the results, it can be seen that the Adams-Bashforth-Moulton method can be used to determine the numerical solution for the SIPAS mathematical model for the spread of monkey business practices.

Abstract

Hybrid ARIMA-NN is a combined approach of the ARIMA model used to capture linear patterns in time series data and Artificial Neural Networks (ANN) to handle non-linear and stochastic patterns. Using a gradient descent algorithm, backpropagation adjusts synaptic weights based on the error between the network's prediction and actual training data values. In this study, a comparison was made between the Backpropagation method and Hybrid ARIMA-NN in forecasting rainfall in Makassar City. Rainfall data in Makassar City uses data from the rainfall measuring station at the Paotere Maritime Meteorological Station in Makassar. The activation functions used are ReLU and Leaky ReLU with epoch parameters set at 350, and learning rates of 0.01, 0.001, 0.0001, and 0.00001. The two best methods selected for further evaluation are Backpropagation with architecture 12-32-16-8-1 and Hybrid ARIMA-NN (ARIMA [4,0,1]-NN 12-256-128-64-1). The ARIMA model (4,0,1) with AIC values of 1303.4 and RMSE 162,369 is the best compared to other models, which aligns with the advantages of backpropagation architecture. The results showed that the Backpropagation method excelled with an RMSE value of 137.320 or 0.1149, indicating high accuracy in forecasting changes in seasonal trends and patterns. Hybrid ARIMA-NN gives good results with RMSE 145.834, as residues contain better nonlinearity compared to ARIMA models (4,0,1), although it shows a slightly higher error rate compared to Backpropagation.

Abstract

Earthquakes pose a major threat in Indonesia, particularly in complex tectonic regions like Sulawesi and Maluku. To support disaster mitigation, this research employs the Self Organizing Maps (SOM) method—an unsupervised technique that reduces data dimensionality into an intuitive two-dimensional form—to cluster earthquake data using four key variables: longitude, latitude, magnitude, and depth. The dataset includes 5,275 earthquake records from 2022, sourced from the Meteorology, Climatology, and Geophysics Agency (BMKG). SOM training produced 25 neurons, which were then grouped into three optimal clusters using hierarchical clustering, validated by internal metrics: the lowest Connectivity Index (296.1512), highest Silhouette Index (0.3304), and a Dunn Index of 0.0058. Cluster 1, with 13 neurons, covers eastern Sulawesi and Maluku, featuring medium magnitude and depth. Cluster 2, with 11 neurons, represents central to southern Sulawesi, characterized by low magnitude and shallow depth. Cluster 3, comprising a single neuron, includes western regions with high-magnitude, very deep earthquakes. Keywords⎯ Clustering, Earthquake, Internal Validation, Self Organizing Maps (SOM).
