Abstract

Tepung pati aren merupakan hasil ekstraksi empulur pada batang aren. Proses pengeringan tepung pati aren bertujuan untuk memperpanjang umur simpan dan meningkatkan nilai harga jual tepung. Pengeringan tepung pati aren yang dilakukan saat ini masih menggunakan cara tradisional atau konvensional dengan menggunakan terpal sebagai lantai pengeringan. Proses pengeringan tersebut menyebabkan tepung pati aren tidak kering sempurna, membutuhkan waktu pengeringan yang lama serta berpotensi masuknya kontaminan seperti debu dan benda asing yang dapat merusak mutu tepung pati aren. Penelitian ini bertujuan untuk melakukan rancang bangun dan uji kinerja alat pengering efek rumah kaca (ERK). Alat pengering hasil rancangan diharapkan dapat mempercepat proses pengeringan serta meningkatkan mutu tepung pati aren. Metode penelitian yang digunakan adalah metode rancang bangun alat. Tahapan penelitian, diantaranya adalah identifikasi masalah, penetapan kriteria perancangan, perancangan alat pengering tipe ERK, perhitungan analisis teknik, pembuatan gambar teknik, pembuatan alat, uji kinerja alat serta pengolahan data. Alat pengering tepung pati aren tipe ERK yang telah dibuat memiliki panjang 4 m, lebar 2 m dan tinggi 1,5 m. Rangka alat pengering menggunakan konstruksi kayu dengan atap pengering berbentuk setengah oval menggunakan plastik UV 6%. Hasil dari pengujian alat didapatkan profil suhu rata-rata alat sebesar 37,2⁰C, RH rata-rata alat sebesar 41,85%, intensitas cahaya matahari rata-rata alat sebesar 301,16 W/m2, suhu bahan rata-rata alat sebesar 31.94⁰C, kadar air hasil pengeringan bahan rata-rata sebesar 15,46% (bb), laju pengeringan rata-rata sebesar 4,10% (bb)/jam, efisiensi alat sebesar 35,94%, serta efisiensi proses pengeringan sebesar 76,69%.

Abstract

Rancakalong village, Sumedang Regency, has been known for its small-scale palm sugar starch processing industry since 2013. This industry produces starch from palm trees, which is crucial for food and beverages. Generally, the processes involved in processing palm sugar starch include (i) splitting of the palm, (ii) grating, (iii) coarse fiber screening, (iv) fine fiber screening, (v) harvesting, and (vi) drying. Initial evaluations indicated that the workers experienced physical discomfort during their work. Therefore, this study aimed to analyze the ergonomic aspects of processing palm sugar starch, including the working posture, standard time, workload, noise, and vibration. Based on the analysis, the risk level for each work element in processing palm sugar starch fell into the high-risk (score 8-10) and very high-risk (score 11-15) categories. These risks cause discomfort due to inappropriate work posture and duration, necessitating significant changes. The standard time required for each work element was as follows: 212.88±28.43 seconds/kg (palm splitting), 363.45±12.90 seconds/kg (grating), 95.08±9.74 seconds/kg (coarse fiber screening), 192.05±21.27 seconds/kg (fine fiber screening), 35.57±5.78 seconds/kg (harvesting), and 1821.01±41.09 seconds/kg (drying). Regarding workload analysis, processing palm sugar starch activities fell into the moderate category with total energy cost (TEC) values ranging from 92.66±1.50 265.55±3.88 kcal/hour. Regarding noise and vibration analysis, the grating work element was identified as the station with the highest exposure, i.e., 96.00±0.82 dB and 1.6±0.05 m/s2, respectively. The results of this study could be used as a basis for developing more efficient work procedures, maintaining health, and improving safety in the processing of palm sugar starch.
