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.

Abstract:This study aims to analyze the effectiveness of using a Smartboard in increasing students' enthusiasm for learning in the Pancasila Education subject in grade V of SDN 07 Mudiak Lawe, Sungai Pagu District, South Solok Regency.…
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.

Abstract:ABSTRACT The objective of community partnership program cluster 2 (CPP-C2) is to provide micro and small-scale layer chicken farmers in Tomohon city with business management procedures based on “biosecurity”. Problems faced…
blems faced by partners, both farm owners and farm workers: 1) lack of knowledge and understanding of the concept and application of biosecurity 2) lack of sanitation application, which increases the risk of diseases emerging and spreading 3) not yet aware that the use of open house system, unfenced farms and no procedures for entering the farm area, are not in accordance with the principles of biosecurity system. The activity was carried out in stages: survey, socialization on the concept and implementation of the 3-zone biosecurity system, provision of disinfectants and examples of regulation for laying hen farming as well as evaluation. The evaluation results show that during the extension activity, out of 8 participants only 2 were actively asking questions, and it turned out they were the farm owners, while the farm workers were passive. It was found after the outreach activity, that the farm owners or farm workers who were partners had not been implemented the 3-zone biosecurity system, therefore outreach activities regarding biosecurity on poultry farm still need to be provided again to them, so that the concept and application of biosecurity will be truly understood and they would be willing to do so. However, at least 2 farms have prepared signboards with rules for entering the farm area. The occurrence of outbreaks and pandemics should be a lesson-learned that biosecurity measures are highly relevant to the saying “it is better to prevent than cure”. If, chicken remain healthy, they produce high-quality and safe products, and so, farmers can minimize health costs and maximize profits, even enabling farms owner to expand their businesses scale. In conclusion, this activity has not been given a significant impact on partner’s farm management because all partners have not been implemented the 3-zone biosecurity system, and it would be better if, all farm owners as decision makers to participate in this kind of activity, as well as the need for synergy between relevant agencies in the livestock sector in Tomohon city and academics with poultry farming business practitioners in an effort to maintain livestock health, poultry communities and maintain food security.
Abstract:Sports-related minor injuries are common occurrences in school-based physical education activities, yet literacy regarding appropriate first aid management remains limited among teachers and students. This community service…
ice program aimed to improve knowledge, skills, and preparedness in managing minor sports injuries through a digital-based educational intervention entitled Smart Recovery. The program was implemented among junior high school (SMP) teachers and students in Banyumas Regency, Indonesia, using a participatory and technology-integrated approach. Activities consisted of program socialization, theoretical and practical training on minor injury management based on the RICE principle (Rest, Ice, Compression, Elevation), and the pilot implementation of the Smart Recovery digital application. Program effectiveness was evaluated using pre-test and post-test assessments, practical skill observations, and user feedback questionnaires. The results demonstrated a substantial improvement in participants’ knowledge, with average scores increasing from 62.4 to 88.6, and 95% of participants successfully performing the RICE procedures correctly after training. Furthermore, 92% of users reported that the digital application facilitated their understanding of injury management, while 87% perceived the platform as user-friendly and applicable for physical education learning. The integration of hands-on training and digital learning media proved effective in enhancing sports injury literacy, digital competence, and safety awareness in school settings. These findings indicate that the Smart Recovery program has strong potential as a sustainable and scalable model for promoting sports safety education within junior high schools.

The SIPAKATAU (Synergy of Local Food and Physical Activity) programme was designed to address these issues through nutritional education, my plate demonstrations, physical activity, and the use of locally sourced, easily accessible food to the community. The activities were carried out over a month in Paccerakkang and Berua villages, involving 24 participants, health cadres, and the Paccerakkang community health centre. The intervention included pre-tests, interactive education, hands-on practice, physical activity monitoring, and health checks before and after the activities. The results showed an increase in knowledge from 50% to 75% in the good category, increased implementation of My Plate, and 75% of participants had sufficient physical activity. Health indicators showed improvement, particularly in cholesterol (normal levels increased from 1 to 7 individuals) and uric acid (100% normal). Blood sugar levels showed improvement, while blood pressure and nutritional status required longer-term intervention. The SIPAKATAU programme proved effective in improving community nutrition and health behaviours and is recommended as a model for community-based NCD prevention.
