Abstract

Financial management among students at SMP Utama has not been conducted in an organized manner. Based on interviews, 57 students across three classes receive daily allowances between IDR 10,000 and IDR 30,000, yet most do not record their income and expenses, potentially reinforcing consumptive spending habits. Most students already own Android smartphones, presenting an opportunity to offer a mobile- based financial management solution. This study aims to design and develop a simple Android -based digital wallet application using the Waterfall development model. The application was built using Android Studio, Java/Kotlin programming language, and Firebase as the real-time data storage backend. Features include account/wallet management, categorized transaction recording, budget management, savings goals, and graphical financial reports. Black Box Testing results confirmed all major application functions operate according to specifications. This application is intended to serve as an effective financial literacy tool for junior high school students.

Abstract

Raudlatul Makfufin Braille Printing Foundation (YARFIN) is a social institution producing Braille books for the visually impaired with a production capacity of 150 books per day. The production process requires book catalogue data in database format before being sent to the printing machine. However, data is still stored manually in separate Microsoft Excel files, making the transfer to the database a time-consuming manual process. This condition hinders the targeted increase in production capacity. This study develops a web-based application using PHP, MySQL, and the PhpSpreadsheet library to automatically convert book data from Excel to MySQL through validation, duplicate cleaning, and column mapping processes. Development uses the waterfall method with data collected through observation and interviews. Black-box testing on 10 scenarios shows a 100% success rate across all features. This system is expected to accelerate production datapreparation and support the improvement of YARFIN's printing capacity.

Abstract

Singkong (Manihot esculenta) merupakan tanaman pangan penting di Indonesia; Namun, produktivitasnya seringkali menurun akibat serangan kutu putih (Phenacoccus manihoti), yang dapat menyebabkan hilangnya hasil panen lebih dari 80%, sehingga diperlukan metode pengendalian yang efektif dan ramah lingkungan. Salah satu alternatif yang dapat digunakan adalah insektisida nabati yang berasal dari daun tuba (Derris elliptica). Penelitian ini bertujuan untuk menganalisis kandungan fitokimia dan menentukan efektivitas ekstrak daun tuba pada berbagai konsentrasi terhadap mortalitas kutu putih. Penelitian ini menggunakan Rancangan Acak Lengkap (RUPS) dengan 5 perlakuan yang diulang 4 kali, sehingga menghasilkan total 20 unit percobaan. Perlakuan yang diterapkan terdiri dari 0% (Kontrol), 1%, 2%, 3%, dan 4% ekstrak daun tuba. Analisis data dilakukan dengan menggunakan ANOVA Satu Arah, diikuti dengan uji Tukey pada tingkat signifikansi 5%, dan analisis probit untuk menentukan nilai LC₅₀ dan LT₅₀. Hasil penelitian menunjukkan bahwa ekstrak daun tuba mengandung senyawa bioaktif yang berperan sebagai insektisida, seperti flavonoid, terpenoid, saponin, tanin, fenol, dan alkaloid. Konsentrasi 4% menghasilkan tingkat kematian tertinggi. Nilai LC₅₀ sebesar 2,3% dan LT₅₀ tercepat yaitu 37 jam diperoleh, menunjukkan bahwa ekstrak tersebut efektif dalam mengendalikan hama.

Abstract

The primary challenge currently faced by Warung Nasi Rames is its daily bookkeeping method, which still relies on manual paper-based recording. This conventional practice frequently leads to lost records, mathematical calculation errors, and difficulties in tracking cash flow. To address these issues, a web-based financial management information system has been successfully developed. The system's development utilizes XAMPP as the local server, integrated with PHP scripting and a MySQL database for data management. Furthermore, the design process is based on a descriptive analysis approach involving field observations, direct interviews, and literature reviews. The core features provided include menu data management, daily income and expense recording, and the instant generation of profit and loss statements. System testing demonstrates a significant increase in efficiency regarding data recap speed and calculation accuracy, owing to the minimization of manual intervention (human error). In conclusion, this digitalization facilitates the owner in evaluating daily profitability while ensuring that cash flow is systematically recorded, thereby supporting better-informed business decisions.

Abstract

Omaira Fas Internet is an Internet service provider (ISP) based on the RT/RW Net WiFi network that specializes in network installation, network maintenance, and customer service. In addition to its full-time staff, the company regularly hosts a significant number of students participating in Field Work Practice (PKL) programs from various vocational schools, with the number sometimes reaching dozens of students during certain periods. Currently, the attendance process at Omaira Fas Internet is still done manually by sending photos to a WhatsApp group as proof of attendance. This process poses several challenges, such as attendance data that is not systematically organized, the difficulty of compiling attendance records, and suboptimal supervision of PKL students. The objective of this internship is to design and develop a web-based attendance system that can assist the company in managing employee and PKL student attendance data more effectively and accurately. The methods used in preparing this report include observation, interviews, and literature review, while the system development method employs the Waterfall model. The developed system features QR code scanning, selfies for attendance validation, office location radius validation, check-in and check-out attendance, leave and sick leave, automatic attendance summaries, user data management, WhatsApp notifications to parents and supervising teachers, as well as report export to Excel and PDF formats. The expected outcome of this system is the creation of a more effective, accurate, and structured attendance process, as well as simplifying the task of managing and reporting attendance data for interns and employees for company administrators.
