Abstract

Penelitian ini bertujuan untuk mengembangkan dan menguji kelayakan perangkat pembelajaran matematika berbasis aplikasi Android yang mengintegrasikan teknologi Google dalam kerangka Technological Pedagogical and Content Knowledge (TPACK) pada materi perbandingan trigonometri untuk siswa kelas X. Metode penelitian yang digunakan adalah Research and Development (R&D) dengan model ADDIE (Analysis, Design, Development, Implementation, Evaluation). Produk yang dihasilkan berupa aplikasi Android Matematika Pedia yang memuat Modul Ajar (MA), Bahan Ajar (BA), dan Lembar Kerja Peserta Didik (LKPD). Hasil validasi ahli menunjukkan bahwa perangkat berada pada kategori valid, dengan skor MA 3,3, BA 3,4, dan LKPD 3,7. Pada tahap implementasi, perangkat menunjukkan tingkat kepraktisan yang tinggi, ditunjukkan oleh keterlaksanaan pembelajaran oleh guru sebesar 88,75% dan siswa 83,01%, serta respons positif guru 100% dan siswa 90,21%. Efektivitas perangkat juga terbukti melalui perbedaan signifikan hasil belajar antara kelas eksperimen dan kelas kontrol sig. (2-tailed) = 0,001 < α = 0,05, dan nilai N-Gain yang lebih tinggi pada kelas eksperimen 0,58 dibandingkan kelas kontrol 0,36. Dengan demikian, perangkat pembelajaran yang dikembangkan memenuhi kriteria valid, praktis, dan efektif.

Abstract

Plantation production is the result of plantation cultivation which includes the of commodities such as coconut, cloves, nutmeg, cocoa, and coffee which have a high sales and economic value and are good for income, as well as being the main source of income for the community's life. Central Maluku Regency is one of the areas in Maluku Province that has great potential in the plantation sector, but the production level between sub-districts shows considerable variation due to differences in geographical conditions, infrastructure, and market access. This study aims to group sub-districts in Central Maluku Regency based on plantation production using a hierarchical cluster analysis approach. Distance measurement uses Single linkage, Average linkage, Complete linkage, and Ward linkage methods. In addition, descriptive analysis, standardization, KMO tests, and multicollinearity tests were carried out with the data used is in the form of plantation production data per sub-district in 2024 sourced from the Central Statistics Agency. Data processing using Microsoft Excel, SPSS, and R applications. The results of the study showed the formation of several sub-district clusters with similar production characteristics, where the Average linkage and Complete linkage methods with the number of clusters as many as three produced the best grouping with the highest Silhouette Score value of 0.477. Each cluster shows the basis for making policies for the development of the plantation sector. These results are expected to be the basis for local governments in formulating plantation development policies that are more targeted and effective.
