Abstract

Marketing agricultural products remains a major challenge for farmers in Toapaya Village, located in Bintan Regency. The selling prices received by farmers are often significantly lower than the market prices paid by end consumers. This is primarily due to the lengthy distribution chain and dependence on middlemen who take a large portion of the profits. Limited market access further weakens the farmers' position in setting prices and marketing their harvest independently. To address this issue, a web-based marketing system is proposed to facilitate direct transactions between farmers and customers, aiming to shorten the distribution chain and increase farmers' income. The system was developed using the Waterfall software development methodology to support a structured, user-oriented development process, while system modeling was carried out using UML to provide a detailed overview of the system flow. The research results indicate that the developed web-based marketing system can simplify the agricultural marketing process and expand market access. System evaluation will be conducted periodically through direct testing to collect feedback from users. Based on testing results, the system has been proven to enhance product accessibility and facilitate online transactions. Therefore, this marketing system is expected to contribute to economic growth, improve farmers' welfare, and serve as a form of digital transformation in the agricultural sector in Toapaya Village, Bintan Regency.

Abstract

This study proposes a blockchain-based student identity card system as a secure and transparent solution for managing digital identities at the senior high school level. The system is designed to address various issues found in conventional identification methods, such as data forgery, physical card damage, and limited verification capabilities. Developed using the Laravel framework and integrated with a private blockchain network, student identity data is hashed and stored permanently. The digital identity is represented as a QR code printed on the student ID card. Identity verification can be performed independently through a web-based application without relying on a central authority. System evaluation was conducted through functional testing using the black-box testing method, as well as user testing to assess reliability, efficiency, and usability. Test results showed that the system was able to verify identities with an average QR code response time of less than 3 seconds and a login success rate of 98%. Therefore, the integration of blockchain technology into the web platform proves to be an innovative and feasible approach to modernizing student identity management. This system contributes to strengthening the digital transformation of secondary education in a secure, efficient, and decentralized manner.

Abstract

Abstract: The selection of the Head of the Computer Laboratory is a process that requires multidimensional considerations, including technical competence, managerial skills, pedagogic skills, communication, as well as work ethics and discipline. Subjectivity or seniority-based selection approaches often do not produce optimal laboratory leaders. This study aims to design and develop SPK based on the integration of AHP and TOPSIS methods as a means to conduct a methodical and unbiased selection of candidates. The stages carried out include: identification of five main criteria based on expert interviews, weighting of criteria using AHP, collection of candidate assessment data, and final ranking using TOPSIS. The weighting results showed that the Technical criteria  had the highest weight of 0.416, followed by Managerial (0.211) and Pedagogic (0.171). Of the ten candidates analyzed, Candidate I obtained the highest preference score of 0.659, indicating a high balance of scores on all three main criteria. Logical validation tests and sensitivity analysis to weight changes showed that the system remained stable, with the position of Candidate I remaining in the first rank despite the change in the weight of the technical criteria (from 0.3 to 0.5). These findings prove that SPK based on AHP-TOPSIS is able to reduce subjectivity and provide consistent and reliable recommendations in the selection process for the Head of Computer Laboratory. Keyword: DSS, TOPSIS, Laboratory, Technical-Managerial-Pedagogic, AHP Abstrak: Pemilihan Kepala Laboratorium Komputer merupakan proses yang membutuhkan pertimbangan multidimensi, meliputi kompetensi teknis, kemampuan manajerial, keterampilan pedagogik, komunikasi, serta etika dan disiplin kerja. Pendekatan seleksi berbasis subjektivitas atau senioritas sering kali tidak menghasilkan pemimpin laboratorium yang optimal. Studi ini bertujuan merancang dan mengembangkan SPK berbasis integrasi metode AHP dan TOPSIS sebagai sarana untuk melakukan seleksi kandidat secara metodis dan tidak bias. Tahapan yang dilakukan meliputi: identifikasi lima kriteria utama berdasarkan wawancara pakar, pembobotan kriteria menggunakan AHP, pengumpulan data penilaian kandidat, dan perankingan akhir menggunakan TOPSIS. Hasil pembobotan menunjukkan bahwa kriteria Teknis memiliki bobot tertinggi sebesar 0,416, diikuti Manajerial (0,211) dan Pedagogik (0,171). Dari sepuluh kandidat yang dianalisis, Kandidat I memperoleh skor preferensi tertinggi sebesar 0,659, menunjukkan keseimbangan nilai tinggi pada ketiga kriteria utama. Uji validasi logis dan analisis sensitivitas terhadap perubahan bobot menunjukkan bahwa sistem tetap stabil, dengan posisi Kandidat I tetap pada peringkat pertama meskipun bobot teknis berubah sifnifikan (dari 0,3 hingga 0,5), hal ini menunjukan metode yang digunakan konsisten dan handal. Temuan ini menunjukan bahwa SPK berbasis AHP-TOPSIS mampu mengurangi subjektivitas dan memberikan rekomendasi yang konsisten serta dapat diandalkan dalam proses seleksi Kepala Laboratorium Komputer. Kata Kunci: SPK, TOPSIS, Laboratorium, Teknis-Manajerial-Pedagogik, AHP
