Abstract

The synthesis of acetins from glycerol is achieved through esterification assisted by a solid acid catalyst and microwave irradiation. Diacetin and triacetin, suitable as biofuel additives, are produced using biogenic silica from bamboo leaves, which is chemically activated with strong acid and calcined. No research has utilized silica catalysts derived from bamboo leaf ash to produce diacetin and triacetin. This study aims to employ bamboo leaf-based heterogeneous catalysts to enhance triacetin selectivity, simplify product purification and separation, and enable catalyst reuse. Furthermore, microwave application can accelerate the reaction time. The best total selectivity for diacetin and triacetin was obtained under operating conditions of 3% catalyst concentration, a 1:6 molar ratio, and 60 minutes of microwave irradiation. The yields of diacetin and triacetin under these conditions were 65.80% and 18.70%, respectively. GC-MS and FTIR analysis confirm the presence of monoacetin, diacetin, and triacetin, with a total selectivity for diacetin and triacetin of 84,50%.

Abstract

Latar Belakang: Pengangkutan sampah merupakan salah satu komponen penting dalam sistem pengelolaan persampahan perkotaan yang berpengaruh terhadap efisiensi operasional dan dampak lingkungan. penelitian ini bertujuan untuk menganalisis efisiensi rute pengangkutan sampah di Kota Lhokseumawe dengan memanfaatkan SIG sebagai alat bantu analisis Metode: Penelitian ini bertujuan untuk mengoptimalkan rute pengangkutan sampah di Kota Lhokseumawe menggunakan pendekatan Sistem Informasi Geografis (SIG). Data yang digunakan meliputi jaringan jalan, 18 Tempat Penampungan Sementara (TPS), dan lokasi Tempat Pemrosesan Akhir (TPA) Alue Lim. Analisis rute terpendek dilakukan dengan metode network analysis berdasarkan bobot jarak dan waktu tempuh. Hasil: analisis menunjukkan bahwa jarak tempuh rute pengangkutan sampah berkisar antara 2,1 km hingga 19,6 km dengan waktu perjalanan 4–39 menit, yang berdampak pada perbedaan konsumsi bahan bakar antar TPS. Kesimpulan: Penerapan rute optimal berbasis SIG berpotensi meningkatkan efisiensi pengangkutan sampah, menekan konsumsi bahan bakar, serta mendukung sistem transportasi sampah yang lebih hemat dan ramah lingkungan di Kota Lhokseumawe.
