Abstract

The rapid advancement of technology has had a significant impact on contemporary life. One of the technologies commonly encountered is the Quick Response Code (QR-Code) and Barcode, both of which serve a similar function, that is, to store information represented in the form of squares and lines. Three squares at the corners of the QR-Code are key to ensuring accurate scanning. Universities are educational institutions that provide Student ID Cards as a means of student identification. This research aims to design a transaction system by utilizing QR-Code technology on Student ID Cards for parking and library transactions, as well as creating a transaction system using digitized Student ID Cards. This study employs the Technology Acceptance Model (TAM) testing method to measure the factors influencing users in utilizing the application. The system design successfully incorporates QR-Codes and can be used as a transaction tool. The TAM testing results from 75 respondents regarding system acceptance conclude that the Perceived Ease of Use (PEOU) variable will influence the Perceived Usefulness (PU) variable by 67.4% and affect the Behavioral Toward Using (BITU) variable by 55.1%.

Abstract

Biodiesel is an alternative fuel substitute for diesel engines produced from vegetable or animal oil through the transesterification reaction process between fatty acid, methanol, and catalyst. However, in its use in diesel engines, there is a decrease in engine performance. This is partly due to the higher viscosity value compared to diesel. Some ways to improve engine performance using biodiesel include adjusting injection pressure and increasing fuel inlet temperature. This study aimed to determine the effect of adding injection pressure and fuel inlet temperature on the performance of diesel engines using B40, such as power, thermal efficiency, sfc, and AFR. This study used a 1-cylinder diesel engine with constant rotation, using five variations of injection pressure 110-150 bar with a 10 bar interval, and five variations of fuel inlet temperature 30˚C-70˚C with a 10˚C intervals, and five loads from 5,000 kg/m2 to 25,000 kg/m2 with a 5000 kg/m2 interval. Testing and data processing were done using the Taguchi method. The results showed that the best diesel engine performance occurred at an injection pressure of 150 bar and a fuel temperature of 60˚C. The predicted performance value achieved under optimal conditions is a power of 2.9 kW at a load of 25000 kg/m2, thermal efficiency of 69.92% at a load of 25000 kg/m2, sfc of 3 x10-5 kg/kJ at a load of 25000 kg/m2, and AFR of 169.23 at a load of 5000 kg/m2. Temperature significantly affects engine performance power, sfc, thermal efficiency, and AFR compared to injection pressure.

Abstract

Electronic commerce or commonly known as e-commerce is a trading activity carried out by sellers and buyers to offer or buy goods or services electronically using electronic payments. With e-commerce, it will certainly facilitate transactions because sellers and buyers do not need to meet in person, and the prices offered are cheaper because sellers do not need to pay rent. With the ease of this transaction, it certainly adds to the competition in the business because the target market is wider. Competition in business is an unavoidable part, now competition in business is getting tougher in various aspects both in terms of production, service and marketing. Many companies want to develop and their products are known by the public and potential buyers, including PT. Glucksindo Makmur, which until now is still using the offline marketing system, namely sales looking for customers from one place to another to offer products. So that an electronic-based sales system is needed. The software used to design this application are PHP, MySQL, and Laravel Framework. The method used in this test is UAT. The results of this study are the presence of an E-Commerce system that can assist customers in placing orders online, knowing information on the type of product they want to buy and a clear and complete company profile. This research has succeeded in implementing the Laravel framework in designing web-based E-Commerce.

Abstract

Zaman Yang dimana serba teknologi ini, dimana teknologi sebuah kebutuhan yang sangat penting dan tidak dapat dipisahkan dari kehidupan manusia. khususnya Stok atau yang biasa disebut Inventory pada suatu perusahaan juga sangat saling bekerjasama erat menggunakan aktivitas dalam mengumpulkan data mengenai kegiatan pada aktivitas proses keluar dan masuknya pada setiap bisnis perusahaan. Lantaran Persedian sangat berpengaruh dan krusial bagi kebutuhan bisnsis perusahaan, Pt. Link Net adalah perusahaan yang bergerak bidang tv kabel dan jaringan. oleh karena itu sistem ini dapat berguna dalam melakukan transaksi keluar masuk barang pada perusahaan. Metode penelitian ini adalah dengan menggunakan metode Black Box Testing yaitu pengujian yang dilakukan oleh user untuk memastikan bahwa sistem yang dibuat sudah sesuai dengan harapan user atau pengguna.permasalahan yang ada di PT. Link Net yaitu dalam melakukan transaksi keluar masuk barang pada gudang masih menggunakan pencatatan buku besar dan excel. maka penulis ingin merancang suatu sistem inventory berbasis web dan dapat diaskses oleh pengguna dimanapun dan kapanpun untuk membantu dalam transaksi keluar masuk barang dan kestabilan stock barang pada Gudang PT. Link Net

Abstract

Dalam era digital saat ini, pemanfaatan teknologi informasi dalam bidang bisnis menjadi kebutuhan yang penting untuk meningkatkan efisiensi dan efektivitas operasional. Usaha mikro kecil dan menengah (UMKM) seperti Dodol Ny. Pang masih banyak yang mengandalkan sistem penjualan konvensional, yang memiliki keterbatasan dalam hal jangkauan pasar, efisiensi proses transaksi, serta pengelolaan data pelanggan dan stok produk. Oleh karena itu, penelitian ini bertujuan untuk menganalisis dan merancang sistem informasi penjualan online berbasis web guna mendukung perkembangan usaha dan meningkatkan daya saing di pasar digital. Penelitian ini menggunakan pendekatan analisis kebutuhan sistem untuk mengidentifikasi fitur utama yang diperlukan oleh pengguna. Proses perancangan dilakukan dengan metode berorientasi objek menggunakan diagram UML (Unified Modeling Language) dan Entity-Relationship Diagram (ERD) untuk merancang basis data yang terstruktur. Implementasi sistem dilakukan dengan mengembangkan platform berbasis web yang mencakup fitur manajemen produk, pemesanan, pembayaran online, serta pelaporan transaksi.

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan efisiensi dan akuntabilitas dalam pengelolaan keuangan lembaga pendidikan berbasis pesantren melalui pengembangan dan penerapan sistem informasi keuangan berbasis cloud. Aplikasi yang dikembangkan memanfaatkan bahasa pemrograman PHP dan sistem manajemen basis data MySQL, yang diintegrasikan pada layanan cloud agar dapat diakses dengan mudah melalui jaringan internet. Penerapan sistem ini dilakukan di Ponpes Khairul Ummah 2 Pekanbaru sebagai bentuk kontribusi teknologi dalam mendukung tata kelola keuangan yang lebih modern dan transparan. Proses pengembangan meliputi instalasi komponen back-end, perancangan dan pengaturan basis data, serta integrasi sistem ke dalam domain dan layanan hosting milik pesantren. Kegiatan ini mengangkat tema: “Penerapan Sistem Keuangan Berbasis Cloud Computing di Pondok Pesantren Khairul Ummah 2 Pekanbaru.” Lingkup pelaksanaan mencakup tiga aspek utama, yaitu: (1) implementasi antarmuka aplikasi dan integrasi basis data ke dalam sistem hosting, (2) konfigurasi serta aktivasi fitur-fitur aplikasi yang mencakup pencatatan transaksi, kas masuk, kas keluar, dan laporan keuangan, dan (3) pengisian data awal serta parameter operasional sesuai kebutuhan lembaga. Hasil dari kegiatan ini menunjukkan bahwa penggunaan sistem berbasis cloud tidak hanya mempermudah pencatatan transaksi keuangan harian, tetapi juga memberikan dampak positif dalam meningkatkan transparansi dan akuntabilitas keuangan pesantren. Dengan demikian, penerapan teknologi informasi ini diharapkan dapat menjadi solusi efektif dalam manajemen keuangan lembaga pendidikan berbasis keagamaan di era digital.
