Abstract

The purpose of this study is produced paperback book-based Integrated Science science literacy as a learning medium. The development procedure included: analysis of students' needs and characteristics, formulating learning goals, the formulation of the material, the preparation of the evaluation instrument, write a script / draft media, expert validation, field trials, and print production script. Expert validation is done by physicists. Expert validation test results state that pocket book-based Integrated Science science literacy in accordance with the design and materials are included in it have been worth it to be used as a medium of learning. Results from field trials showed pocket book Integrated Science science literacy based designs are very interesting and very effectively used as a medium of learning.Tujuan penelitian ini yaitu menghasilkan buku saku IPA Terpadu berbasis literasi sains sebagai salah satu media pembelajaran. Prosedur pengembangan ini meliputi: analisis kebutuhan dan karakteristik siswa, perumusan tujuan pembelajaran, perumusan butir-butir materi, penyusunan instrumen evaluasi, menulis naskah/draf media, validasi ahli, uji coba lapangan, dan mencetak naskah produksi. Validasi ahli dilakukan oleh ahli fisika. Hasil uji validasi ahli menyatakan bahwa buku saku IPA Terpadu berbasis literasi sains telah sesuai dengan desain serta materi yang mencakup di dalamnya telah layak untuk digunakan sebagai media pembelajaran. Hasil dari uji coba lapangan menunjukan buku saku IPA Terpadu berbasis literasi sains desainnya sangat menarik dan sangat efektif digunakan sebagai media pembelajaran.Kata kunci: buku saku, literasi sains, media pembelajaran, penelitian pengembangan

Abstract

The rise of social media platforms, particularly Twitter, has transformed how individuals express opinions and concerns. Companies, like Spotify, leverage platforms such as Twitter for customer support and feedback gathering. This research delves into the world of Spotify Cares tweets using K-Means and K-Medoids clustering methods, aiming to enhance customer support analysis. The study employs the silhouette coefficient and the Davies-Bouldin Index (DBI) to evaluate clustering quality. With an extensive dataset covering more than 3 million Twitter customer service interactions, including 29,479 notes specific to Spotify Cares, this investigation uncovered latent patterns and themes. The versatility of K-Means and K-Medoids, proven effective in a wide range of applications, is highlighted. Therefore, K-means and K-medios were implemented in this research. The results show that K-Means, with 10 clusters (K = 10), with a DBI value of 1.76, shows moderate dispersion, indicating the potential for improvements for better segmentation precision. In contrast, K-Medoids, with 2 clusters (K = 2) and a lower DBI of 1.48, present a clearer and more compact clustering structure. This implies simplified customer categories, which is beneficial for targeted support. In conclusion, although both methods have strengths and weaknesses, K-Medoids with two clusters emerges as a promising method for Spotify Cares, offering cohesive customer groupings for efficient intervention. Future research efforts could focus on refining parameters and exploring the complex relationships between response time, sentiment analysis, and customer satisfaction to achieve a more nuanced analysis.

Abstract

The arrangement of facilities and infrastructure for the Integrated School District on the road Purnama Agung V, Pontianak City is an effort to maintain the stability of nature and the function of an area that prioritizes secondary needs such as providing beauty, comfort and providing enthusiasm for learning as well as providing an attraction for residents or visitors in the area. Integrated School. The Integrated School area planning stands on an area of ​​1.94 ha consisting of 4 schools including the Early Childhood Education (PAUD) school building, SD Country 15 Pontianak South, SMP Country 22 Pontianak and SMA Country 10 Pontianak. The location of the Integrated School is located on the road Agung Purnama V, South Pontianak sub-district, Pontianak city, West Kalimantan. The planning for the arrangement of the Integrated School area with a total area of ​​1,94 Ha but that will manage with a land area of ​​0,76 Ha will be planned for green open spaces, playgrounds, reading parks, environmental roads, parking lots vehicles, drainage channels and placement of trash cans, as an effort to support the educational process and protect the environment in Indonesia, especially in the city of Pontianak, West Kalimantan.

Abstract

Abstract—Indonesia is one of the second largest agricultural countries in the world after Brazil. Most of Indonesia's population works in agriculture. This sector accounts for 13.28% of gross domestic product in 2021. Indonesia's very strategic location, starting from the geographical side, causes Indonesia to be in a tropical area which has two seasons. These factors make Indonesia very suitable for the agricultural sector. However, the distribution process of rice yields in Indonesia has many obstacles, including the habit of local farmers selling through collectors so that the profit margin obtained is relatively small. In this final project, a solution called ByTani is proposed (a website-based online agricultural trading platform), a trading platform for agricultural products that will connect farmers with buyers directly so that farmers' profits can increase. Based on a survey conducted by the author on March 1, 2022, to farmers in the West Java area, data obtained that 66.7% of farmers have privately owned rice fields. Of all the farmers interviewed, all sold their produce to local collectors in their area. The sale of crops to collectors creates another problem, namely that farmers become dependent on collectors and have narrow sales targets. Meanwhile, 66.7% of farmers stated that the purchase price from collectors was relatively cheap compared to the total costs incurred during the process of planting rice to harvesting. Based on the test results, 68.5% of farmers agree with the problem that the collector's purchase price is quite low. Based on the solutions offered, 73.3% of farmers agree that the ByTani application as an intermediary for selling farmers' crops can help increase the profit of selling rice.Keywords— Indonesia, agriculture, farmers, collectors, application
