Abstract

Tujuan dari penelitian ini adalah untuk mengetahui secara empiris pengaruh variabel kualitas sistem (system quality), kualitas informasi (information quality) dan kualitas layanan (service quality) terhadap kepuasaan pengguna (user satisfaction) dalam penggunaan SIAKAD online berbasis Web. Responden dalam penelitian ini berjumlah 252 mahasiswa. Data primer dalam penelitian ini dikumpulkan pada bulan April 2017 sampai Mei 2017. Teknik pengambilan sampel menggunakan purposive sampling, yaitu peneliti dengan sengaja mengambil mahasiswa Strata satu (S1) yang telah menempuh perkuliahan selama 3 (tiga) semester atau lebih sebagai sampel. Metode pengumpulan data primer menggunakan kuesioner. Data dianalisis menggunakan regresi linear berganda dengan bantuan program SPSS version 17,0 for Windows. Berdasarkan review literatur, model penelitian ini mengadopsi Model Kesuksesan Sistem Informasi DeLone & McLean (update, tahun 2003). Hasil peneltian menunjukkan bahwa kualitas sistem (system quality), kualitas informasi (information quality), dan kualitas layanan (service quality) berpengaruh positif dan signifikan terhadap kepuasaan pengguna (user satisfaction) SIAKAD online berbasis Web pada Universitas Jambi.

Abstract

Produktivitas padi sawah di Desa Teluk, Kecamatan Pemayung, Kabupaten Batanghari mengalami penurunan dalam lima tahun terakhir akibat penggunaan pupuk kimia berlebihan, degradasi kesuburan tanah, dan minimnya pengetahuan petani tentang teknologi pupuk organik. Program pengabdian masyarakat ini bertujuan untuk mentransfer pengetahuan pemanfaatan pupuk organik guna meningkatkan produktivitas dan pendapatan usahatani padi sawah. Metode yang digunakan adalah Community Based Participatory Development (CBPD) dengan pendekatan learning by doing, technology transfer, dan community empowerment. Kegiatan meliputi sosialisasi, penyuluhan, pelatihan praktik pembuatan pupuk organik JAKABA (Jamur Keabadian) dan JADAM, serta monitoring dan evaluasi. Hasil program menunjukkan peningkatan hasil panen, efisiensi biaya produksi, perbaikan kualitas tanah, dan peningkatan kemandirian petani. Pupuk JAKABA memiliki tingkat adopsi lebih tinggi dibandingkan JADAM karena kemudahan bahan baku dan proses pembuatan. Program ini berhasil membentuk kelompok tani pengolah pupuk organik dan berpotensi untuk direplikasi di wilayah lain, mendukung pertanian berkelanjutan dan ketahanan pangan nasional.

Abstract

Vendor selection at PT. Manufaktur Digital Jaya is still prone to subjectivity and bias that focuses on price, which risks causing production bottlenecks and quality decline. This decision is a complex Multi-Criteria Decision Making (MCDM) problem and requires an objective and structured assessment. This research aims to design a Decision Support System (DSS) to determine the best vendor at PT. Manufaktur Digital Jaya, using a combination of the Analytical Hierarchy Process  (AHP) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) methods. The AHP analysis was validated using Expert Choice software and the TOPSIS calculations were performed with Microsoft Excel. The AHP method is used to determine the priority weights of the assessment criteria, while TOPSIS is used to rank the vendor alternatives based on their closeness to the ideal solution. Five main criteria were established, covering Product Quality (C1), Unit Price (C2), Delivery Accuracy (C3), Service Capacity (C4), and Reputation (C5). The results of the AHP analysis show that Product Quality (C1) and Service Capacity (C4) are the criteria with the highest weights, reflecting the company's strategic priority on quality and long-term support.

Abstract

Data is an essential asset that must be protected due to its strategic role in maintaining the continuity of information systems. Therefore, data security becomes a crucial aspect in information management. One of the approaches to ensure data security is through the application of cryptographic techniques. Two commonly used classical cryptographic algorithms are the Rail Fence Cipher and the Vigenere Cipher. However, the use of a single algorithm has weaknesses, as it remains vulnerable to brute-force attacks. This study aims to combine two cryptographic methods, namely the transposition technique (Rail Fence) and the substitution technique (Vigenere), to enhance resistance against brute force attacks. The research employs an experimental method by implementing the combined algorithms using the Python programming language. Testing was conducted on three scenarios: encryption using Rail Fence, Vigenere, and their combination. The results show that the combined algorithm increases key space and produces more complex character distribution patterns, thereby improving security against brute-force attacks.

Abstract

The quality of public service is a crucial factor for companies such as the Regional Water Company. The main challenges often faced are the slow handling of customer complaints, difficulty in accessing billing information, and the bureaucratic process of new connection registration. This research aims to design and build an integrated web and mobile-based customer service information system. The research method used is the Waterfall model, which includes the stages of requirements analysis, system design, implementation, and testing. The result of this research is the customer service application, which consists of three platforms: (1) A back office web for administrators, supervisors, and superadmins to manage master data, monitor, and delegate complaints and reports; (2) An Android Mobile Application for Customers, featuring online complaints, complaint tracking, new connection registration, bill checking, self-service meter reading, and news information; (3) An Android Mobile Application for Field Officers, which functions to receive and update the status of complaint work orders. The implementation of this system has successfully transformed manual business processes into digital ones, thereby increasing response speed, data transparency, and customer satisfaction one of them is PERUMDA Air Minum Tirta Mayang.
