Abstract

Secara umum, untuk setiap buah durian secara proporsional terdapat kandungan buah durian sebesar 20-35% dari berat buah, biji 5-15%, dan sisanya merupakan kulit yaitu 60-75%. Sehingga lebih dari 60% produksi buah durian adalah menghasilkan limbah. Untuk tahun 2019 di Sumatera Utara potensi produksi buah durian sebesar 90.105 Ton, tumbuh 8,73 % dari sebelumnya 82.872 ton per tahun (sumber: BPS dan Direktorat Jendral Hortikultura) dengan potensi sampah kulit durian 59.147 Ton sampah kulit durian dimanah kondisi ini diperparah oleh dibuang sembarangannya kulit tersebut dipinggir jalan dan parit/ got, hal ini dapat menjadi salah satu penyebab banjir jalan dan timbulnya penyakit. Penelitian ini bertujuan membuat teknologi yang bermanfaat sebagai alternatif energi yang berdasarkan kesimpulan yaitu untuk membuat satu kompor portabel briket didapat dengan biaya Rp 405.500. Dari hasil percobaan briket dengan menggunakan kompor portabel waktu pembakaran yang didapat untuk satu briket adalah 2,5 jam Untuk menggunakan kompor dibutuhkan biaya Rp 550.500 sebagai biaya awal untuk penggunaan

Abstract

Boolean logic learning is a fundamental competency that must be mastered by Informatics Engineering students as a foundation for understanding digital computation and programming concepts. However, the presentation of theoretical materials often makes it difficult for students to visualize the relationship between binary inputs and logical operation outputs, which leads to a low level of conceptual understanding. This study aims to develop a web-based Boolean logic learning medium that integrates the Pyodide engine to provide interactive simulations directly within a browser environment. The application is designed to assist students in understanding Boolean logic operations through truth table visualization, binary input simulations, and mini-game features as learning exercises. The research method employs a prototyping approach consisting of needs analysis, system design, application implementation, and user evaluation stages. The evaluation was conducted through pilot testing involving five Informatics Engineering students from Universitas Pamulang to assess the application’s functionality, usability, and initial user acceptance as a learning medium. The results indicate that the application produces outputs that are consistent with Boolean logic truth tables and achieves a high level of user acceptance. These findings suggest that the developed learning medium has the potential to serve as an effective interactive learning tool in supporting students’ initial understanding of Boolean logic concepts prior to broader-scale testing.
