Abstract

The integration of technology in the learning process remains a significant challenge, especially in remote areas like SMA Negeri 4 Seram Bagian Timur. Limited infrastructure and low technological literacy among teachers have led to a lack of innovation in delivering learning materials. This activity aims to improve digital literacy and skills in creating technology-based learning media using Canva. The partner in this activity is SMA Negeri 4 Seram Bagian Timur, targeting 28 students and 1 teacher. The implementation of the activity is carried out in three stages: preparation, implementation, and evaluation. In the preparation stage, materials and tools are prepared. The implementation involves direct training using a Knowledge Transfer approach and the Community Development Model. The training sessions include an introduction to Canva, a workshop on creating media, and mentoring in the design process. Evaluation is done through pre-tests, post-tests, and response questionnaires. The results showed an average post-test score increase to 84.82 from 63.75 in the pre-test. The N-Gain analysis indicated a 57.82% improvement. Recommendations from this activity include the need for ongoing support for infrastructure and advanced technology training so that the skills gained can be consistently applied in the learning process

Abstract

Curah hujan merupakan unsur iklim krusial yang mempengaruhi ketersediaan air, siklus pertanian, dan risiko bencana hidrometeorologi. Pola curah hujan di Kota Ambon menunjukkan variabilitas dan periodisitas yang tinggi, sehingga memerlukan metode pemodelan yang mampu menangkap karakteristik nonlinier dan musiman secara akurat. Penelitian ini bertujuan untuk membandingkan kinerja model Spline Truncated dan Deret Fourier dalam pemodelan data curah hujan bulanan di Kota Ambon periode Januari 2020 hingga Desember 2024. Variabel terikatnya adalah curah hujan, sedangkan suhu udara, kelembaban udara, kecepatan angin, dan tekanan udara merupakan variabel bebas yang diperoleh dari publikasi Badan Pusat Statistik (BPS) Ambon dan BMKG Provinsi Maluku. Analisis menggunakan regresi nonparametrik menggunakan estimator Spline Truncated dan Deret Fourier. Titik knot optimal untuk model Spline ditentukan menggunakan Generalized Cross Validation (GCV), dan jumlah harmonisasi optimal untuk model Fourier dipilih berdasarkan Akaike Information Criterion (AIC) minimum. Hasil menunjukkan bahwa model Fourier dengan dua harmonik memberikan kinerja terbaik dengan R^2 sebesar 0,5719 dan AIC sebesar 820,8226, mengungguli model Spline Truncated. Kelembapan, tekanan udara, dan komponen harmonik sinus (2) berpengaruh signifikan terhadap curah hujan. Oleh karena itu, model Deret Fourier direkomendasikan untuk merepresentasikan tren curah hujan bulanan di Kota Ambon.
