kondisi pasar. PT Victoeria Vici, sebagai pelaku usaha perhiasan emas custom, menghadapi kendala dalam menentukan estimasi harga jual kepada pelanggan, sebab proses pengerjaan pesanan custom membutuhkan waktu hingga 14 hari, sementara harga emas bergerak fluktuatif dan tidak terstruktur setiap harinya sehingga estimasi harga menjadi tidak akurat dan tidak efektif. Berdasarkan permasalahan tersebut, penelitian ini menerapkan konsep Data Mining dengan algoritma Trend Moment untuk mengestimasi harga emas pada rentang waktu tertentu. Data yang digunakan merupakan data historis harga emas per gram pada PT Victoeria Vici periode Agustus–Oktober 2021 sebanyak 92 data. Tahapan penelitian meliputi pengumpulan data, penentuan variabel X dan Y, eliminasi untuk memperoleh nilai konstanta a dan slope b, serta penerapan persamaan Y = a + bX untuk memperoleh nilai estimasi. Hasil perhitungan menunjukkan nilai a = 720.871,725 dan b = 3,108 sehingga model estimasi mampu menghasilkan proyeksi harga emas yang mendekati pola data historis. Model ini kemudian diimplementasikan ke dalam aplikasi berbasis desktop menggunakan Microsoft Visual Basic 2010 dan basis data Microsoft Access, dilengkapi Crystal Report untuk pencetakan laporan hasil estimasi. Hasil penelitian menunjukkan bahwa algoritma Trend Moment dapat membantu PT Victoeria Vici dalam memperoleh estimasi harga emas secara lebih cepat, konsisten, dan terdokumentasi.
Gold is one of the most sought-after commodities for investment purposes, as it is regarded as a safer instrument compared to stocks and has a selling value that constantly fluctuates with market conditions. PT Victoeria Vici, a custom gold jewelry business, faces difficulty in determining the estimated selling price offered to customers because the production process for custom orders takes up to 14 days, while gold prices move in an unstructured and fluctuating manner every day, making manual price estimation inaccurate and ineffective. Based on this problem, this study applies the concept of Data Mining using the Trend Moment algorithm to estimate gold prices over a certain period of time. The data used is historical daily gold price data per gram from PT Victoeria Vici for the period of August–October 2021, consisting of 92 records. The research stages include data collection, determination of the X and Y variables, elimination to obtain the constant value a and the slope b, and the application of the equation Y = a + bX to obtain the estimated value. The calculation results show a value of a = 720,871.725 and b = 3.108, so that the estimation model is able to produce gold price projections that closely follow the pattern of historical data. This model was then implemented into a desktop-based application using Microsoft Visual Basic 2010 and a Microsoft Access database, equipped with Crystal Report for printing estimation result reports. The results show that the Trend Moment algorithm can help PT Victoeria Vici obtain gold price estimations more quickly, consistently, and in a well-documented manner.

penanggulangan yang telah dilakukan sekolah. Menggunakan pendekatan kualitatif deskriptif dengan desain studi kasus, data dikumpulkan melalui observasi lapangan, studi dokumentasi data Dapodik, dan wawancara mendalam terhadap empat informan kunci yang terdiri dari kepala sekolah dan jajaran guru senior. Analisis data kuantitatif populasi siswa secara longitudinal disajikan menggunakan metode grafik perilaku sepanjang waktu atau Behaviour Overtime Graphs (BOTG). Hasil penelitian menunjukkan adanya tren penurunan populasi siswa yang bersifat linier berkelanjutan selama periode enam tahun ajaran terakhir (2019/2020 hingga 2025/2026), dengan jumlah akhir hanya tersisa 24 siswa aktif. Faktor internal yang menjadi pelemah utama adalah keterbatasan sarana prasarana pembelajaran yang masih tradisional. Sementara itu, faktor eksternal dominan meliputi hambatan aksesibilitas geografis, pergeseran demografi akibat penurunan angka kelahiran, ketatnya kompetisi antarlembaga, serta minimnya dukungan kebijakan tata pamong desa. Krisis jumlah siswa ini berdampak pada pasifnya dinamika psikososial kelas kecil dan peningkatan beban kerja emosional guru. Strategi insentif jangka pendek berupa pembagian paket seragam gratis terbukti belum efektif memulihkan volume input siswa. Kesimpulannya, penurunan siswa di sekolah ini merupakan kegagalan adaptasi struktural dalam perspektif teori pendekatan sistem akibat ketidakselarasan antara instrumen internal dengan tekanan lingkungan makro.

gency. From initial observations, it was seen that students' enthusiasm for learning tended to be low, as seen from their inactive attitudes, little interaction, and easily distracted when teachers used less diverse learning methods. To address this, a Smartboard was proposed as an innovative solution. This tool is an interactive whiteboard that uses multimedia and audiovisual technology, so it can combine teaching materials with images, videos, and animations to make learning more interesting and diverse. The method used in this study was the correlation method, namely a quantitative method that studies the relationship between the use of Smartboard interactive features and the level of student enthusiasm for learning. The results showed that the use of Smartboard in learning was proven to be able to increase student enthusiasm for learning. After implementing the Smartboard, students appeared more active and enthusiastic during the learning process, so that their enthusiasm for learning increased and reduced boredom. The implementation of Smartboard involves game-based learning methods such as Duck Race Games and Wordwall, which successfully trigger students' curiosity, focus, and enthusiasm, and encourage them to actively participate in answering questions and interacting in class.
