PHYSICOCHEMICAL CHARACTERISTICS OF SAGO STARCH OBTAINED FROM FLUIDIZED BED DRYING USING SOLAR AND BIOMASS POWERED CROSS FLOW FLUIDIZED BED DRYER. The research aim is to study the comparative quality of sago starch drying results using cross flow fluidized bed dryer powered by solar and biomass in conventional drying, particularly the chemical composition and physicochemical characteristics. This research was conducted through a drying phase of wet sago starch using a cross flow fluidized bed dryer, and drying in conventional as well as dried sago starch quality testing results are drying. The results of this study indicate that dry sago starch which has been drained by means of cross flow fluidized bed dryer has a chemical composition that does not vary much with starch which is dried by conventional drying, so that the dried sago starch produced by the dryer is very good. On the other hand the use of dryers is the more correct because the physicochemical properties of sago starch using a low drying temperature and drying time is short. Tujuan penelitian ini adalah mempelajari perbandingan kualitas pati sagu hasil pengeringan menggunakan alat pengering cross flow fluidized bed bertenaga surya dan biomassa dengan pengeringan secara konvensional, khususnya komposisi kimia dan karakteristik fisikokimia. Penelitian ini dilakukan melalui beberapa tahapan yaitu pengeringan pati sagu basah menggunakan alat pengering cross flow fluidized bed, pengeringan secara konvensional serta pengujian kualitas pati sagu kering hasil pengeringan. Hasil dari penelitian ini menunjukkan bahwa pati sagu kering yang telah dikeringkan dengan alat pengering cross flow fluidized bed memiliki komposisi kimia yang tidak berbeda jauh dengan pati yang dikeringkan dengan cara pengeringan secara konvensional, sehingga pati sagu kering yang dihasilkan oleh alat pengering tersebut sangat baik. Di sisi lain penggunaan alat pengering ini semakin memperbaiki sifat fisikokimia pati sagu sebab menggunakan suhu pengeringan yang rendah dan waktu pengeringan yang singkat. Kata Kunci: pengering unggun terfluidakan; fisikokimia; pati sagu
In order to produce sago starch, sago bar had to be crushed and extracted using water to separate starch from other compounds. In the sago processing, a lot of water was used to extract sago starch and finally was discarded as liquid waste. In this study, the quality of sago liquid waste, before and after applying a layer-based filter containing: coir, charcoal, gravel and sand, was measured. The study was designed with a different time of storage of the Sago liquid waste, namely 0,1,2,3,4, and 5 day of storage. Each day the liquid waste was filterd using layer-based filter, and then the quality of the liquid waste was compared. The parameters measured were total suspended solids, total dissolved solids, final pH, and physical parameters such as smell and color. The results of this study showed that quality decrese of sago liquid waste accurs during 5 days of storage as indicated by increasing the total suspended solids (up to 1400 mg/L) and the dissolved solids (up to 2000 mg/L), decresing the pH value (down to 5) and arising unpleasant smells. Furthermore, the use of the layer-based filter was effective enough to restore the quality of the sago liquid water by decreasing the total solids, neutralizing the pH value and reducing the unpleasant smell.
Pengering Agitated Fluidized Bed (AFB) telah dirancang untuk pengeringan pati sagu. Untuk mengetahui kinerja pengering AFB tersebut, maka dilakukan analisis nilai indeks kinerja Heat Utilization Factor (HUF), Coefficient Of Performance (COP), Effective Heat Efficiency (EHE), dan Specific Energy Consumption (SEC) berdasarkan perlakuan suhu (50oC, 60oC, dan 70oC) dan massa input bahan (3 kg, 6 kg, dan 12 kg). Nilai indeks kinerja HUF, COP, EHE dan SEC ditentukan dengan analisis matematis. Hasil penelitian ini menunjukkan bahwa indeks kinerja pengering AFB terbaik dari semua perlakuan suhu dan massa input bahan adalah pada suhu 60oC dengan massa input bahan 12 kg, dimana nilai HUF lebih besar dari nilai COP. Nilai HUF, COP, dan EHE masing-masing adalah 53,1%, 46,9%, 70,3% dan nilai SEC 559,9 kJ/s. Nilai rata-rata HUF, COP, EHE, dan SEC dari semua perlakuan pada pengering AFB adalah 37,23%, 62,7%, 58,5%, dan 337,6 kJ/s. Kinerja pengering AFB cukup rendah, dimana nilai HUF rata-rata lebih kecil dari nilai COP rata-rata, dan energi yang digunakan cukup tinggi. Namun demikian, pengering AFB mampu mengeringkan pati sagu dengan kadar air akhir 14,4% basis basah mendekati standar mutu pati sagu kering 13%, pada suhu 70oC dengan massa bahan sebanyak 3 kg selama 5 menit (300 detik).
Pengolahan pascapanen pokem khususnya pada tahapan perontokan masih dikerjakan secara konvensional/tradisional sehingga cara ini sangat rumit dan kurang efisien serta kapasitas yang terbatas. Tujuan penelitian ini adalah melakukan evalusi teknik-ekonomi alat perontok pokem mekanis . Hasil pengujian diperoleh rata-rata kapasitas perontokkan 17,60 kg/jam, rata-rata efisiensi perontokan 86,80 % dan rata-rata persentase pemisahan malai 96.40% . Hasil evaluasi finansial diperoleh Net Present Value (NPV ) = Rp. 20,317,066, Nett Benefit-Cost Ratio (B/C) = 2,49, Internal Rate Return (IRR )= 64% dan Pay Back Period (PBP ) = 1,5 tahun. Berdasarkan analisis finansial maka penggunaan alat perontok ini layak.
