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.

o access funding. This study aims to assist Al Huda Plastic and Baking Supplies Store in Kebumen in preparing financial statements in accordance with the Financial Accounting Standards for Micro, Small, and Medium Entities (SAK EMKM). This topic was chosen due to the importance of accounting literacy in managing small businesses, as the understanding of MSME actors regarding accounting standards is still relatively low. This research uses a descriptive qualitative method with a case study approach, utilizing observation, semi-structured interviews, and documentation as data collection techniques. The results show that Al Huda Store has been recording its finances manually. However, these records do not yet cover the components of financial statements required by SAK EMKM, such as the income statement, statement of financial position, and notes to the financial statements. The preparation of financial statements based on these standards has been carried out and demonstrates more accurate and structured financial information. In conclusion, the implementation of financial statements based on SAK EMKM in MSMEs plays a very important role in increasing accountability and quality in business decision-making. The results of this study also provide practical examples that can be used as references and re-applied by other MSMEs with similar characteristics

Abstract:The transition into emerging adulthood frequently induces life-direction anxiety, commonly known as a quarter-life crisis, among university students. This correlational quantitative investigation was designed to evaluate…
the correlation between the intensity of the quarter-life crisis (Variable X) and self-esteem (Variable Y) among active students at the State Christian Institute of Kupang (IAKN Kupang). Employing a sample of 30 participants gathered via probability sampling techniques, data collection was conducted utilizing Likert-scale questionnaires and statistically processed using the Pearson Product Moment correlation formula. The empirical analysis demonstrates a significant and highly robust positive correlation between the investigated constructs ($r = 0.769$; $p = 0.000$). This outcome highlights a noteworthy theoretical anomaly, wherein heightened levels of crisis are unexpectedly linked with enhanced self-esteem. This distinct psychological pattern is driven by active internal introspection, a purposeful pursuit of life meaning, and personal identity consolidation amid adversity. Furthermore, the campus culture at IAKN Kupang—characterized by comprehensive spiritual mentoring, robust peer networks, and a nurturing social atmosphere—serves as a constructive emotional buffer. These external dynamics empower students to navigate developmental stress adaptively, demonstrating that rather than diminishing their self-worth, the identity crisis ultimately bolsters their personal resilience.
