Abstract: Developing reading habits is part of empowering education; therefore, reading habits should be instilled from an early age. However, not all children can experience facilities such as reading various types of reading books… ks that suit their interests and preferences, as is the case with children in orphanages. As a response, this community service plays a part in increasing children’s interest in reading. The program we proposed, namely Reading Corner, took place at Imanuel Orphanage in Palangka. The program was carried out by assessing the needs, designing the Reading Corner, and implementing it. Reading Corner serves as a facility for extensive reading at home. Reading Corner allows the children to read various types of books based on their preferences. The result of this program indicated that the children looked enthusiastic about the books as they chose and borrowed the book to read. The closer children are to the books, the more often they will use their time to access and read the books. In line with that, it is expected that the literacy level of Indonesian will increase. Keywords: reading corner; reading interest; reading habit   Mengembangkan budaya membaca merupakan bentuk dari penyelenggaraan pendidikan, maka dari itu budaya membaca harus ditanamkan sejak dini pada anak.

Sinuraya, Khairul Abdi, Sinuraya, Insan Utama, Toras Pangidoan Batubara
Abstract: Abstract: The assessment of PKH employees in Batu Bara Regency still requires an objective and measurable evaluation process to support performance decisions. Manual assessment can cause subjectivity and take more time,… especially when several criteria must be considered. This study aims to apply the Simple Additive Weighting (SAW) method to the PKH employee assessment system in Batu Bara Regency. The criteria used in this assessment are attendance, teamwork, responsibility, communication, and length of service. The SAW method is applied by determining criteria weights, converting employee values, normalizing the decision matrix, and calculating preference values to obtain the final ranking. The results show that alternative A1, Rahmi Rizkya, obtained the highest score of 0.9504 and ranked first, while alternative A5, Toni Syahpradanadaely, obtained the lowest score of 0.4831. Based on these results, the SAW method can help the employee assessment process become more objective, structured, and useful as a reference for evaluating PKH employee performance.

WEB-BASED ELEMENTARY SCHOOL SELECTION DECISION SUPPORT SYSTEM USING A COMBINATION OF SMART AND TOPSIS METHODS

Maharani, Dewi, Marpaung, Nasrun
Abstract: Abstract: Choosing the right elementary school is a crucial milestone for a child's future. However, the large number of school options in Asahan Regency with diverse criteria such as accreditation, facilities, fees, curriculum,… riculum, and accessibility often makes it difficult for parents. Decision-making tends to be based on subjective word-of-mouth recommendations, which risks triggering bias. This research aims to develop an adaptive and objective web-based elementary school selection Decision Support System (DSS) framework to minimize such bias. The system is designed using a hybrid model that combines the Simple Multi-Attribute Rating Technique (SMART) method as a dynamic criteria weighting engine based on parents' preferences, and the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) method to rank ten alternative schools. System testing was conducted through black-box testing functionality and empirical accuracy testing using Spearman Rank Correlation involving 40 respondents. The black-box testing results confirmed that all main system operations ran perfectly with a 100% success rate. Validity testing demonstrated very high accuracy, with a Spearman correlation coefficient of 0.89, demonstrating significant alignment between the system's recommendations and actual choices on the ground. Thus, the SMART-TOPSIS framework has proven reliable as a data-driven approach to helping parents choose the best elementary school.

Namun, banyaknya pilihan sekolah di Kabupaten Asahan dengan keberagaman kriteria seperti akreditasi, fasilitas, biaya, kurikulum, dan aksesibilitas sering kali menyulitkan orang tua. Pengambilan keputusan pun cenderung didasarkan pada rekomendasi subjektif dari mulut ke mulut, yang berisiko memicu bias. Penelitian ini bertujuan mengembangkan kerangka kerja Sistem Pendukung Keputusan (SPK) pemilihan sekolah dasar berbasis web yang adaptif dan objektif guna meminimalkan bias tersebut. Sistem dirancang menggunakan model hibrida yang mengombinasikan metode *Simple Multi-Attribute Rating Technique* (SMART) sebagai mesin pembobotan kriteria dinamis sesuai preferensi orang tua, serta metode *Technique for Order of Preference by Similarity to Ideal Solution* (TOPSIS) untuk memeringkat sepuluh sekolah alternatif. Pengujian sistem dilakukan melalui uji fungsionalitas *black-box testing* dan uji akurasi empiris menggunakan Korelasi Peringkat Spearman dengan melibatkan 40 responden. Hasil *black-box testing* mengonfirmasi seluruh operasi utama sistem berjalan sempurna dengan tingkat keberhasilan 100%. Uji validitas menunjukkan akurasi sangat tinggi dengan koefisien korelasi Spearman sebesar 0,89, membuktikan keselarasan signifikan antara rekomendasi sistem dan pilihan nyata di lapangan. Dengan demikian, kerangka SMART-TOPSIS ini terbukti andal sebagai pendekatan berbasis data untuk membantu orang tua memilih sekolah dasar terbaik.

Abstract: Abstract: Managing fast-moving drug inventory requires accurate supplier selection to ensure product availability and minimize the risk of overstock and out-of-stock conditions. At Annisa Pharmacy, the supplier selection… process has traditionally relied on experience and subjective judgment, which may lead to less optimal decisions. This study aims to design and implement a Decision Support System (DSS) for selecting fast-moving drug suppliers using the Weighted Product (WP) method. The WP method is applied because it is capable of processing multiple criteria simultaneously through structured weighting, including demand frequency, delivery lead time, remaining shelf life, purchase price, and profit margin. The system is developed as a web-based application using PHP and MySQL. The results show that the implementation of the Weighted Product method successfully produces preference values and accurate supplier rankings, enabling the system to correctly determine the most optimal fast-moving drug supplier based on the defined criteria. Therefore, the developed system can assist the owner of Annisa Pharmacy in making more precise, objective, and structured inventory procurement decisions. Keywords: decision support system; drug inventory; supplier selection; weighted product.   Abstrak: Pengelolaan stok obat fast moving di Toko Obat Annisa memerlukan ketepatan dalam menentukan supplier agar ketersediaan obat tetap terjaga dan risiko overstock maupun out of stock dapat diminimalkan.
