Abstract

This study aims to develop a decision support system (SPK) for the selection of new students at YPPK Christ Raja Junior High School in Jayapura using the Vikor (Multi-criteria Decision Analysis) method. The main problem faced by the school is the selection process of new students who still use a manual system, causing errors in decision making. The vikor method was chosen because it is efficient in handling multi-criteria problems. This study involved 15 students as an alternative sample in the selection process. The vikor method is used for normalization, calculation of utility measure (s) and regret measure (r) values, as well as determination of index values. The ranking results are based on the s, r, and q sequences, with the best alternative solution determined based on the minimum q value. The results showed that recommendations for new student admission decisions can be obtained by utilizing the ranking results from the vikor method. The system development process is carried out using the waterfall method with stages of software requirements analysis, design, program code creation, and testing. System design is carried out using structured design, while testing uses the blackbox method. The results of this study are expected to improve the efficiency and accuracy of the selection process for new students at YPPK Christ Raja Junior High School in Jayapura through the implementation of a decision support system with the vikor method.

Abstract

Penelitian ini meningkatkan teknik backward chaining untuk diagnosis Demam Berdarah Dengue (DBD) dengan mengintegrasikan algoritma backtracking, dengan tujuan untuk meningkatkan efisiensi penelusuran gejala dan aturan dalam sistem pakar. Hasil eksperimen menunjukkan bahwa penggunaan backtracking secara signifikan mengurangi waktu pemrosesan dibandingkan dengan metode tanpa backtracking. Pada eksperimen yang melibatkan 3 aturan, waktu pemrosesan berkurang dari 168,50 ms menjadi 19,53 ms, sementara untuk 6 aturan, waktu pemrosesan turun dari 161,63 ms menjadi 20,88 ms. Demikian pula, dalam pengujian dengan 10 aturan, waktu pemrosesan menurun dari 161,68 ms menjadi 17,38 ms. Secara keseluruhan, integrasi algoritma backtracking meningkatkan efisiensi penelusuran rata-rata sebesar 88%, terbukti menjadi pendekatan yang sangat efektif, terutama dalam sistem pakar yang memiliki banyak aturan dan gejala.   Kata kunci: Backward Chaining, Backtracking, Diagnosis DBD, Efisiensi

Abstract

This study aims to analyze the Quality of Service (QoS) of the internet network at Universitas Sepuluh Nopember Papua as part of efforts to support academic activities, particularly online learning. The network quality was evaluated using Wireshark software based on QoS parameters, namely throughput, packet loss, delay, and jitter. Data were collected through direct observation of network usage conditions, interviews with Information and Communication Technology (ICT) managers, and a literature review related to the TIPHON standards. The study's findings revealed that network conditions varied according to traffic density. During low-traffic periods, throughput reached 2.355 Mbps, packet loss was 0%, delay was 15.794 ms, and jitter was 8.329 ms, all of which fall into the excellent category. However, during peak hours, throughput dropped to 23.918 Kbps, with packet loss reaching 86.21%, indicating significant disruptions. Based on these results, the study recommends optimizing network infrastructure, increasing bandwidth capacity, and managing user traffic to ensure more stable internet service quality and better support for academic activities.Keyword: Quality Of Service; Wireshark; TIPHON AbstrakPenelitian ini bertujuan untuk menganalisis kualitas layanan jaringan internet (Quality of Service/QoS) di Universitas Sepuluh Nopember Papua sebagai bagian dari upaya mendukung aktivitas akademik, terutama pembelajaran daring. Kualitas jaringan dievaluasi menggunakan perangkat lunak Wireshark berdasarkan parameter-parameter QoS, yaitu throughput, packet loss, delay, dan jitter. Data dikumpulkan melalui observasi langsung pada kondisi penggunaan jaringan, wawancara dengan pengelola Teknologi Informasi dan Komunikasi, serta studi literatur terkait standar TIPHON. Hasil penelitian menunjukkan bahwa kondisi jaringan bervariasi sesuai tingkat kepadatan lalu lintas. Pada kondisi sepi, throughput mencapai 2,355 Mbps, packet loss 0%, delay 15,794 ms, dan jitter 8,329 ms, yang semuanya berada dalam kategori sangat baik. Namun, pada jam sibuk, throughput menurun menjadi 23,918 Kbps dengan packet loss mencapai 86,21%, mencerminkan gangguan signifikan. Berdasarkan hasil ini, penelitian merekomendasikan optimasi infrastruktur jaringan, peningkatan kapasitas bandwidth, dan manajemen lalu lintas pengguna untuk memastikan kualitas layanan internet yang lebih stabil dan mendukung kegiatan akademik secara optimal.

Abstract

PT. Sinarta Karya Papua, a medium-scale enterprise in Eastern Indonesia, faces operational challenges due to its reliance on manual sales recording systems, leading to data duplication, delayed reporting, and limited information transparency. This hinders operational efficiency and strategic decision-making. This study aims to develop a web-based sales management information system addressing these issues using the Rapid Application Development (RAD) methodology, selected for its rapid prototyping and iterative adaptation to user needs. Data was gathered through field observations, semi-structured interviews with staff and management, and literature reviews on information systems and RAD. The system was developed with PHP and MySQL to ensure flexibility and reliable data management. Findings demonstrate the successful integration of sales transaction processing, customer management, inventory control, and real-time reporting modules. Comprehensive functional testing (Blackbox Testing) confirmed 100% operational accuracy across all features, significantly improving record-keeping efficiency and information accessibility. The primary contribution lies in implementing RAD within Papua's unique business context—an underexplored area in existing literature. The system delivers a practical solution for PT. Sinarta Karya Papua while serving as a reference model for similar enterprises in geographically challenging regions. Key implications include enhanced organizational competitiveness through digital transformation and the potential replication of this framework across other business sectors in Eastern Indonesia.
