Abstract

ABSTRAKPada jaman dahulu masyarakat Nusantara kita ini tidak mengenal tulisan, sehingga segala pengetahuantentang arsitektur tidak tertulis dan dianggap bahwa rumah adat yang ada tidak dikatakan sebagai sebuah karyaarsitektur. Sedangkan kondisi sekarang ini wujud fisik arsitektur sudah tersedia, literatur mengenai rumah adattiap daerah sudah ada walau terbatas. Tetapi kondisi masyarakat di jaman modern ini, perkembangan teknologiyang semakin canggih membuat generasi muda saat ini lebih kecanduan gadget, segala informasi danpengetahuan melalui media online. Sedangkan pengetahuan tentang rumah adat tiap daerah sangatlah terbatas,sehingga tidak heran jika generasi muda cenderung tidak memahami rumah adat tiap daerah. Penelitian inimembatasi hanya pada pemahaman wujud fisik arsitektur Batak dengan tiga variasi, yaitu Batak Karo, BatakToba dan Batak Simalungun. Tujuan penelitian ini adalah untuk menambah wawasan kepada generasi mudamengenai wujud fisik arsitektur Batak, agar kekayaan budaya bangsa Indonesia tetap dapat dilestarikan. Metodepengumpulan data dengan menggunakan observasi di lapangan dan literatur mengenai detail dari wujud fisikarsitektur Batak Karo, Toba dan Simalungun. Analisis data dalam penelitian ini dilakukan dengan cara analisisdeskriptif, yaitu menyeleksi data yang diperoleh dari lapangan berdasarkan kualitas kebenarannya, dandihubungkan dengan data yang diperoleh dari literatur tentang Batak Karo, Toba dan Simalungun. Kesimpulandari penelitian ini bahwa banyak dari generasi muda belum mengenal arsitektur Batak Karo, Toba danSimalungun, sehingga memang diperlukan pemahaman mengenai arsitektur Batak dari berbagai media.Kata kunci : Arsitektur Batak, Generasi Muda, Pengenalan, Wujud FisikABSTRACTIn ancient times our Archipelago community did not know writing, so all knowledge of architecture was notwritten and it was assumed that the existing Nusantara house was not said to be an architectural work. Whereasthe present condition of the physical form of architecture is available, the literature on Nusantara houses in eachregion already exists even though it is limited. But the condition of society in modern times, increasinglysophisticated technological developments make the younger generation today more addicted to gadgets, allinformation and knowledge through online media. While the knowledge of Nusantara houses in each region isvery limited, so it is not surprising that the younger generation tends to not understand the traditional houses ofeach region. This research limits only the understanding of the physical form of Batak architecture with threevariations, namely Batak Karo, Batak Toba and Batak Simalungun. The purpose of this study is to add insight tothe younger generation regarding the physical form of Batak architecture, so that the Indonesian culturalrichness can still be preserved. Methods of collecting data using field observations and literature on the detailsof the physical form of Karo, Toba and Batak Simalungun architectures. Data analysis in this study was carriedout by means of descriptive analysis, namely selecting data obtained from the field based on the quality of itstruth, and related to data obtained from the literature on Karo, Toba and Batak Simalungun. The conclusion ofthis study is that many of the younger generation are not familiar with the Karo, Toba and Batak Simalungunarchitecture, so it is indeed necessary to understand Batak architecture from all media.Keywords : Architecture Batak, Young Generation, Introduction, Physical Being

Abstract

Data and information are essential in various fields today, as well as in the field of education, especially in universities. Some universities already have information systems that support data and information needs. However, the system has not been integrated, so it cannot provide data and information needs quickly and in an integrated manner. Information systems in universities are still primarily departmental because each was built at a different time and uses another platform. The departmental nature of this information system causes inaccuracies and inconsistencies of data that drive the information produced in reports and data reused in transactions to be invalid. Invalid data, in the end, also impacts decision-making taken by management. This study aims to develop a data warehouse at a university to integrate academic data using a star schema. The method used is the Nine Step Methodology. The result of this research is data warehouse architecture used in the academic field; fact tables and ERDs have been designed at the current stage of designing a Prototype of the Study Program Performance Sheet (LKPS).

Abstract

The current era is marked by rapid technological advancements, with e-commerce being one of the most prominent innovations that caters to people's needs and saves time. In this study, we examine the factors that significantly influence user satisfaction in Shopee, a popular e-commerce platform, using the End User Computing Satisfaction (EUCS) method. Data was collected through the distribution of questionnaires to students in the DKI Jakarta area. Our analysis revealed that Content, Accuracy, Format, Ease of Use, Timeliness, and Fulfillment are all significant factors that affect user satisfaction. Together, these factors explain 78.7% of user satisfaction. Additionally, through T-tests, we found that only three variables have a significant and positive impact on user satisfaction: Ease of Use, Timeliness, and Fulfillment. These findings indicate that e-commerce platforms should prioritize these factors to enhance user satisfaction.

Abstract

Education infrastructure in Indonesia faces significant challenges and inequity between urban and rural areas. Differences in education facilities, teacher qualifications, and access to technology are key issues in improving the quality of education across the country. In this context, an efficient education infrastructure system and the software applications that support it are crucial to achieving educational equity. This study adopted the Extreme Programming (XP) software development method to develop an education infrastructure application focusing on school data management. The results of this study show that the education infrastructure application based on the XP method successfully identified the initial requirements strongly and focused on the most essential features. User Acceptance Testing (UAT) provided valuable feedback, highlighting the strengths and weaknesses of the application; the user satisfaction rate was 82%. It was found that the app has the potential to fulfil user needs, although some improvements are needed, especially in certain features such as the Inventory module. Future research could focus on the continued development of the education infrastructure app, taking into account user suggestions and feedback. Further research involves more stakeholders, including parents and students, in testing and improving the app. This research highlights the importance of developing software applications that support equitable and efficient education infrastructure in Indonesia.
