Abstract

Abstract: The development of information technology has experienced rapid growth, especially the internet. The internet has made significant contributions, particularly in the business sector. The intense business competition and the rapid advancement of information technology have facilitated greater accessibility for customers in choosing industries. The Mazzuri Batu Bara industry is a business that sells coconut oil products and handcrafted items made from coconut. However, Mazzuri Batu Bara has not yet implemented services that make it easier for customers to purchase products efficiently and still relies on manual processes. Sales reports are recorded in ledgers, making the process inefficient for maintaining organized records. Customers are required to visit the industry in person to learn about the products available, which means they are unaware of the latest discounts and products on offer. One of the strategies to improve service and operations is to implement a Customer Relationship Management (CRM) system. The objective of this research is to assess the operability of the system design that has been developed. With the CRM design, sales can be enhanced to better meet customer needs. This system is designed to facilitate Mazzuri Batu Bara in selling products, processing data digitally, and improving customer service loyalty by retaining existing customers and attracting new ones.Keywords: coconut oil; e-crm; industry mazzuri batu bara.  Abstrak:  Perkembangan teknologi informasi telah mengalami pertumbuhan yang sangat pesat terutama internet.

Abstract

Abstract: The implementation of Geographic Information Systems (GIS) within organizations has become essential in accomplishing work activities in the modern era. Sideak Motor is a financing company in Kisaran City, Asahan Regency, that provides loans using motorcycle registration certificates (BPKB) as collateral, with a customer base reaching 6,052. Sideak Motor faces difficulties in data management. During meetings concerning customer locations, data communication with owners and office staff is often problematic. Additionally, when duties are transferred, new field officers struggle to locate customers because the previous officers could only provide textual information. As a result, office staff have no precise knowledge of customer locations—only the field officers do. This study aims to design a web-based customer mapping system to facilitate information storage, reduce costs, save time, and produce an information system that enhances the efficiency and accuracy of customer data management. The resulting system presents the distribution of customer locations and provides accessible information such as personal data, addresses, route details, and photos of customers’ homes, thereby simplifying the operations of Sideak Motor.Keywords: customer distribution mapping; geographic information system (GIS); sideak motor. Abstrak: Penerapan sistem informasi geografis dalam organisasi menjadi hal utama untuk menyelesaikan suatu aktivitas pekerjaan pada era sekarang ini.

Abstract: Asahan District Library Service is a growing regional public library and is always making improvements, improvements, and trying to maintain the quality of its services. This is evidenced by the provision of services such as borrowing and returning books (circulation), and adding to the book collection every year. Knowing and understanding visitors' reading interests is the main key in improving the quality of library services. However, managing reading interest from various levels of society is not an easy task. Each individual has different reading preferences and interests. Therefore, a systematic and efficient approach is needed in identifying reading interests to be able to manage the addition of book collections. Currently, in the process of adding a book collection, the library only makes employee recommendations, and the latest books, as a reference in increasing the number of book collections, without considering which books are most in demand to increase the collection. This can have a negative impact if there is an addition to the collection of books that are not in demand to read, which can cause problems in terms of service and finance. Based on this, the application of data mining, especially the K-Means method, will be carried out, to support the management of book collection additions, by grouping the reading interests of library visitors who have the same identity, so that libraries are more precise in managing book collections in grouping books that are rarely borrowed, often borrowed and very often borrowed.  Keywords: visitor reading interest; k-means method; library; data mining; book collectionAbstrak: Dinas Perpustakaan Kabupaten Asahan merupakan perpustakaan umum daerah sedang berkembang dan terus memperbaiki, membenahi, dan meningkatkan layanan. Diberikannya layanan seperti pinjaman dan sirkulasi, dan penambahan koleksi buku setiap tahunnya. Mengetahui dan memahami minat baca pengunjung menjadi kunci utama dalam meningkatkan kualitas layanan perpustakaan. Namun, mengelola minat baca dari berbagai lapisan masyarakat bukanlah tugas yang mudah. Setiap individu memiliki preferensi dan minat baca yang berbeda-beda. Oleh karena itu, diperlukan suatu pendekatan yang sistematis dan efisien dalam mengidentifikasi minat baca untuk dapat mengelola penambahan koleksi buku. Saat ini, ketika perpustakaan meningkatkan koleksi bukunya, mereka hanya bergantung pada rekomendasi karyawan dan buku terkini untuk menambah jumlah buku. Mereka tidak mempertimbangkan buku mana yang paling diminati untuk menambah koleksi mereka. Hal ini dapat berdampak negatif jika terdapat penambahan koleksi buku yang kurang diminati untuk dibaca, yang dapat menimbulkan masalah dari sisi pelayanan maupun finansial. Berdasarkan hal tersebut maka akan dilakukan penerapan data mining khususnya metode K-Means, untuk mendukung pengelolaan penambahan koleksi buku, dengan cara mengelompokkan minat baca pengunjung perpustakaan yang memiliki kesamaan identitas, sehingga perpustakaan lebih tepat dalam mengelola koleksi buku dalam mengelompokan buku yang jarang dipinjam, sering dipinjam dan sangat sering dipinjam.Kata Kunci: minat baca pengunjung; metode k-means; perpustakaan; data mining; koleksi buku

Abstract

Background Morbus Hansen (MH) is a granulomatous infectious disease of the skin caused by Mycobacterium leprae, which induces skin lesions and peripheral nerve injuries that can cause physical disabilities. The basis of the diagnosis of MH is based on classic clinical signs, characteristic histopathological findings and demonstration of acid-fast bacilli in skin biopsies. However, determining neurovascular involvement in a granulomatous reaction is challenging in pathologic diagnosis. S100, a marker of pheripheral nerve, may aid MH diagnosis. The aim of this study to determine different pattern of S100 immunostaining in paucibacillary and multibacillary type MH. Methods This research was an analytic cross-sectional study. Sample was MH patients who underwent a skin biopsy and was examined for histopathology by routine H&E staining and Ziehl Neelsen (ZN) staining at the Anatomical Pathology Laboratory, Faculty of Medicine, Udayana University/Prof.Dr. I.G.N.G Ngoerah hospital, Denpasar from 2017 to 2022. Clinical information, histopathological examination results and ZN stain data were obtained. Pattern of neurovascular damage was determined by S100 immunohistochemistry and catagorized into intact infiltrated pattern and reduced/fragmented infiltrated patterns. The association between MH type and S100 staining pattern was analyzed by Chi-square test with a significance value of p<0.05. Results The results showed that the staining pattern in paucibaciler type MH was mostly reduced/fragmented infiltrated pattern, meanwhile in multibacillary type MH was mostly intact infiltrated pattern. There was a significant different S100 immunostaining pattern in Paucibaciler and Multibaciler MH (p=0.001). Conclusion S100 immunostaining can identify differences in staining patterns in cases of paucibacillary and multibacillary MH types. S100 may used as aditional testing to determine neurovascular involvement.

Abstract

This article examines the factors that contribute to successful principal leadership at SMA Negeri 1 Bunut. Principal leadership is pivotal to the quality of teaching–learning processes and student outcomes; understanding the critical determinants of effective leadership can strengthen secondary-school leadership, particularly in under-researched regional contexts. The study aimed to analyse those critical factors from the principal’s experience and perspectives. A qualitative case-study approach was adopted. Data were collected through in-depth interviews with the principal, supplemented by field observation and document review, and were analysed using thematic analysis and source triangulation. Six overarching themes were identified: motivation to serve in one’s home region; strategies emphasising collaboration, discipline, and collegiality; transformational leadership; direct communication and communication via social media; role modelling as a critical factor; instructional leadership; and a focus on process. Leadership effectiveness was assessed in terms of academic and non-academic achievement, teacher and staff satisfaction, management effectiveness, and achievement of the school’s vision and mission. In sum, successful leadership at SMA Negeri 1 Bunut is underpinned by role modelling, transformational leadership, and attention to both instruction and students’ character development. Other principals and policymakers are encouraged to prioritise role modelling, teacher professional development, instructional leadership, and process-oriented evaluation.
