Abstract

Non-oil and gas exports are exports carried out outside the gas and oil sectors. Some examples of Indonesia's non-oil and gas export commodities are: Coffee beans, Tea, Spices, Tobacco, Cocoa beans, Shrimp, Textiles, Processed wood products, Palm oil, Chemicals, and others. Export activities are one component of aggregate expenditure because exports can affect the level of national income to be achieved. If exports increase, aggregate expenditure will increase and will then stimulate a country's economic growth. This value can be predicted using the trend moment method which is developed for upward trend data patterns. The stages of this method explain the problem of predicting the Value of Non-Oil and Gas Exports in 2023-2024 using the trend moment method. This method is carried out by looking at the trend line in past data and then applying mathematical principles to the stages of the calculation processes. The test results show that the accuracy of the trend moment prediction model in the 2023-2024 Non-Oil and Gas Export Value data is classified as good with a good Mean absolute percentage Error (MAPE) calculation percentage.

Abstract

Parents' hope for their children pursuing formal education is to get maximum test scores and graduate with good grades. Thus, some efforts are made by parents to increase children's understanding of learning. Non-formal education at tutoring institutions is one of the parents' efforts. However, not all parents can provide tutoring facilities through non-formal institutions. Concrete steps are needed from various elements of society to overcome these problems, one of which is a lecturer. Lecturers carry out community service (PKM) by giving free mathematics tutoring at the elementary level within the Badung Bali Kencana Bakti Semesta Foundation (YKBS). The PKM aims to develop good learning habits, increase learning motivation, and increase learning achievement in mathematics. Tutoring is carried out 14 times, held on Wednesdays and Saturdays. The material provided refers to the students' textbooks and worksheets. A series of activity methods, namely (1) warming up through giving motivation to learn (2) explaining the material, (3) questions and answers, (4) quiz, (5) giving gifts, (6) giving post-test. The PKM activity can improve students' learning outcomes, as shown by the post-test results. The development of student motivation also shows good results, shown by the enthusiasm of students who ask for continuous tutoring activities.

Abstract

Tourism is a vital sector in the economic development of Bali Province, with the number of international tourist arrivals through I Gusti Ngurah Rai International Airport as the main indicator. According to data from the Central Statistics Agency (BPS), the number of international tourists reached its peak in 2019 with over 16.1 million visits. However, in 2020–2021, there was a drastic decline due to the COVID-19 pandemic. In 2022, the number of international tourist arrivals began to show a significant recovery. In 2023, the number of international tourist arrivals to Indonesia reached 11.68 million, most of whom entered through major airports such as I Gusti Ngurah Rai Airport (Bali). The inaccuracy of the tourist arrival grouping process has had a negative impact on business growth and tourism revenue. This study aims to classify the countries of origin of international tourists based on the number of visits using the K-Means Clustering method, an effective unsupervised data mining algorithm for data segmentation. Data was obtained from the Central Statistics Agency (BPS), covering the number of tourist arrivals and their countries of origin from 2018 to 2024. The analysis process involves determining the optimal number of clusters using the Elbow Method, followed by grouping countries based on visit characteristics. The results of the study indicate that tourist countries of origin can be grouped into three main clusters: high-visit countries (Australia and China), medium-visit countries, and low-visit countries. This study provides strategic insights for the government and tourism industry stakeholders in developing more targeted policies, such as improving transportation infrastructure and implementing more effective marketing strategies to maintain and increase the number of tourist visits to Bali.

Abstract

Latar belakang: Seorang pendidik mempunyai tugas untuk selalu mengembangkan diri secara teknik pembelajaran atau penelitian. perkembangan teknologi ternyata belum mampu memberikan hasil yang diharapkan. Sering sekali kita temukan beberapa pendidik atau peneliti diantaranya: 1) masih menggunakan hardcopy sebagai bahan penelitian dan perhitungan, 2) kebanyakan bahan ajar yang digunakan untuk proses media pembelajaran tersaji dalam bentuk text. 3) kurangnya keterampilan seorang pendidik dalam menyampaikan materi berbasis aplikasi software. Tujuan: Program ini dilaksanakan agar para guru dalam membuat media pembelajaran, pengelolaan data, atau penelitian dapat menggunakan aplikasi statistika terutama aplikasi software minitab yang dapat menghasilkan perhitungan otomatis dengan tingkat keakuratan serta penarikan kesimpulan yang lebih akurat. Metode: Salah satu tahap kegiatan program pengenalan dan pelatihan aplikasi software minitab yaitu dilaksanakan dengan beberapa tahap: 1) observasi dan wawancara terkait keterampilan guru-guru dalam pembelajaran dan penelitian menggunakan aplikasi software matematika; 2) pengenalan dan pendampingan penggunaan aplikasi software minitab; 3) praktik dan uji coba pengolahan data menggunakan aplikasi software minitab; 4) membuat media pembelajaran melalui aplikasi software minitab; serta 5) memberikan kuesioner untuk melihat perkembangan setelah pelatihan aplikasi software minitab. Hasil: Melalui program pengenalan dan pelatihan aplikasi software minitab, menunjukkan peserta para guru sudah dapat mengenal dan menggunakannya. Berdasarkan dari hasil pemberian nilai kuesioner, dapat disimpulkan kegiatan pengabdian pengenalan aplikasi software minitab meningkatkan kretivitas para guru dalam menggunakan aplikasi software minitab sebesar 96% dibandingkan dengan sebelum program pengenalan dan pelatihan. Kesimpulan: program pengenalan dan pelatihan aplikasi software minitab yang tepat akan memberikan dampak perkembangan para guru dalam media pembelajaran dan penelitian menggunakan aplikasi.

Technological developments have not been able to provide the expected results. Very often we find educators or researchers including: 1) still using hardcopy as material for research and calculations, 2) most of the teaching materials used for the process of learning media are presented in text form. 3) the lack of skills of an educator in delivering material based on software applications. Objective: This program is implemented so that teachers in creating instructional media, data management, or research can use statistical applications, especially the Minitab software application which can produce automatic calculations with a more accurate level of accuracy and draw conclusions. Method: One of the stages of the introduction and training program for Minitab software applications is carried out in several stages: 1) observation and interviews related to the skills of teachers in learning and research using mathematical software applications; 2) introduction and assistance in the use of Minitab software applications; 3) data processing practices and trials using the Minitab software application; 4) create learning media through minitab software applications; and 5) giving a questionnaire to see developments after the Minitab software application training. Result: Through the Minitab software application introduction and training program, it shows that the participants are teachers who are able to recognize and use it. Based on the results of scoring the questionnaire, it can be concluded that the minitab introduction service activity increased the creativity of teachers in using the Minitab software application by 96% compared to before the introduction and training program. Conclusion: the introduction and training program for the proper Minitab software application will have an impact on the development of teachers in learning media and research using applications.   Keywords: learning tools, data management, minitab program
