| dc.description.abstract | Gula semut sebagai pemanis alami membutuhkan proses pengeringan yang
efisien untuk memenuhi standar mutu industri dan mempercepat produksi.
Penelitian ini bertujuan menguji performansi prototipe mesin pengering tipe rotary
dryer dalam menurunkan kadar air gula semut hingga target maksimal 2,5%.
Pengujian dilakukan dengan variasi kecepatan putar 23,83 ± 0,1 RPM dan 41,83 ±
0,1 RPM serta waktu pengeringan 1, 2, dan 3 jam pada kapasitas 500 g per batch.
Semua perlakuan berhasil menurunkan kadar air di bawah target 2,5%, memenuhi
SNI 01-3743-2021 dan standar internal perusahaan. Kombinasi optimal ditentukan
menggunakan metode Simple Additive Weighting (SAW) pada kecepatan 23,83 ±
0,1 RPM selama 1 jam dengan kadar air akhir 2,4%, susut tercecer 14,4%, dan
biaya energi terendah Rp821. Kecepatan tinggi meningkatkan susut tercecer hingga
55,07% akibat gaya sentrifugal dan distribusi panas yang tidak merata. Gula semut
yang menempel pada dinding silinder menunjukkan perlunya perbaikan desain sirip
dan aliran udara. Penelitian ini merekomendasikan pemanas yang lebih stabil,
perluasan variasi kecepatan putar (15–50 RPM) dan suhu (60–80°C), serta integrasi
kontrol otomatis untuk aplikasi industri skala kecil-menengah. | |
| dc.description.abstract | Granulated palm sugar requires efficient drying to meet industrial quality standards
and accelerate production. This study aimed to evaluate the performance of a
prototype rotary dryer in reducing moisture content to a maximum target of 2.5%.
Tests were conducted at rotation speeds of 23.83 ± 0.1 RPM and 41.83 ± 0.1 RPM
with drying durations of 1, 2, and 3 hours using a 500-g batch capacity. All
treatments successfully reduced moisture below the 2.5% target, meeting SNI
01-3743-2021 and the company’s internal standards. The optimal condition,
determined using the Simple Additive Weighting (SAW) method, was 23.8 ± 0.1
RPM for 1 hour, resulting in a final moisture of 2.4%, a product loss of 14.4%, and
the lowest energy cost of Rp 821. Higher rotation increased the product loss to
55.07% due to centrifugal forces and uneven heat distribution. Sugar adhering to
the cylinder walls highlighted the need for improved fin design and airflow. Future
development should incorporate stable heating, expanded rotation speed (15–50
RPM) and temperature (60–80°C) variations, and automatic controls for small- to
medium-scale food industry applications. | |
