Abstract

Tujuan penelitian ini adalah pengembangan proses pembuatan CBS Minyak Inti Sawit (Refined Bleached Deodorized Palm Kernel Oil, RBDPKO) dengan proses hidrogenasi lalu membandingkan karakter fisikokimia CBS dari RBDPKO dengan beberapa jenis CBS komersial.  Tahapan penelitian yang dilakukan adalah (1) Pembuatan CBS RBDPKO melalui optimasi proses hidrogenasi dan rafinasi; (2) Analisis bahan baku dan produk CBS dari RBDPKO; (3) Karakterisasi produk CBS dan membandingkan dengan CBS komersial. Dari hasil penelitian didapat kondisi optimum proses hidrogenasi CBS RBDPKO adalah menggunakan katalis nikel 0,1% pada alat hidrogenasi (reaktor) kapasitas 5 liter, dengan suhu 184°C, tekanan 2,5 bar, lama proses 6 jam, kecepatan aduk 250 rpm, dilanjutkan proses penyaringan dengan alat filter press, proses bleaching menggunakan bentonit 1% pada suhu 90°C selama 45 menit, proses deodorisasi denganalat rafinasi pada suhu 220°C selama 1,5 jam dan penyaringan kembali dengan alat filter press. Pada kondisi tersebut dapat diperoleh CBS asal RBDPKO dengan tekstur, warna dan bau yang mirip dengan CBS asal RBDPKO komersial, kadar air 0,07%, bebas kotoran, bilangan Iod 2,16 gram Iod/100 gram, asam lemak bebas 0,61% , tidak mengandung asam lemak trans dan nikel, titik leleh berubah dari 26,25°C menjadi 34°C, yaitu berubah wujud menjadi padat, terjadi penjenuhan asam oleat dan asam linoleat oleh atom hidrogen menjadi asam stearat sebagai tanda bahwa terjadi hidrogenasi penuh dan memiliki solid fat content 6,62% pada suhu 35°C dan 1,80% pada suhu 40°C mirip dengan profil SFC CBS komersial dan mempunyai profil triasilgliserol (TAG) yang serupa dengan CBS komersial lainnya.

Abstract

In order to obtain the better mushroom drying operation, it requires proper information of its equilibrium moisture content (Me) and drying constant since it was very useful for storag.The objective of this research was to design  Me and K models.The models were function of drying temperature and designed based on infinite slab and sphere geometry.The experiments were conducted at 35,40,45,and 50 degree C,on blanched/unblanched condition and were operated at drying air velocity of 1.0 1.5 2.0, and 2.5 m/s.The Me and K models based on infinite slab gave better results.

Abstract

Penelitian mengenai pengaruh proses pengolahan terhadap kandungan skopoletin pada produk singkong telah dilakukan. Tujuan penelitian ini untuk mengetahui karakteristik perubahan kandungan skopoletin pada pasca panen dan pengolahan singkong. Ruang lingkup penelitian mencakup pembuatan produk antara ( mokaf dan tapioka) dan produk olahan dari singkong (singkong goreng, kripik singkong, singkong rebus dan singkong kukus) serta analisis kandungan skopoletin pada tahapan proses pembuatan produk antara dan produk akhir sedangkan hasil analisis kandungan skopoletin pada produk menunjukkan adanya penurunan kandungan skopoletin. Persentase kandungan skopoletin produk antara dan produk akhir terhadap kandungan awal pada bahan baku bervariasi antara 5,77% (keripik singkong) sampai 97,10% (mokaf) Proses pengolahan singkong untuk konsumsi langsung yang dapat mempertahankan kandungan skopoletin cukup tinggi adalah proses kukus (72,35%)

Abstract

When vitamin A undergoes oxidation in fatty food, two possible types of oxidation should be considered. Firstly, there is a possibility for the vitamin A to react directly with oxygen. However, it is also possible to be oxidised by the products of autoxidation of the lipid. This work is set out to study the rate of autoxidation of vitamin A. It is shown that this process is relatively slow. The factors which influence the rate of autoxidation were also explored.

Abstract

The study was aim at obtaining the optimal acetylation and activation time for obtaining water insoluble acetylated pectin which would be used for bioplastic material. The activation time for swelling of pectin were 120, 180, and 240 minutes, meanwhile the acetylation time were 60, 90, and 120 minutes. The experiment revealed that the activation time of 180 minutes and acetylation time of 120, 180, and 240 minutes, meanwhile the acetlylation time were of 60, 90, and 120 minutes. The experiment revealed that the activation time of 180 minutes and acetylation time 120 minute, produced water insoluble (hydrophobic) material were diluted in dimethly sulfoxide, and the highest actyl subsitution was 62.9% (wb). Infrared spectrospic analysis indicated that the absoption band of pectin and the acetylated pectin were different at wave number 1743 cm1 of which the ester group of the material can be detected. The analysis of pectin acetate structure by stereophotomicroscope revealed that the highest surface density was resulted from activation time and acetylation time of 120 minutes. Moreover, the best result of the bioplastic sheet of pectin acetate was produced by using pressure of 100 Psi at temperature of 100oC for 5 minutes pressure.

Abstract

Dalam lima tahun terakhir belum diketahui secara akurat peran investasi dalam menciptakan Nilai Tambah Bruto (NTB) dan penyerapan tenaga kerja dalam sektor industri makanan. Tujuan penelitian ini adalah menganalisis berapa besar peran investasi sektor industri makanan dalam menciptakan 1) NTB, 2) penyerapan tenaga kerja, 3) import content, dan 4) indeks backward linkage dan forward linkage. Data diolah dengan Tabel I-O pada 66 sektor industri dengan tahun dasar 2010. Investasi di sektor industri makanan periode 2007–2011 rata-rata sebesar Rp 12,39 triliun per tahun, terbukti dapat menciptakan NTB riil sebesar Rp 4,22 triliun juta per tahun di sektor bersangkutan, dengan elastisitas investasi terhadap NTB sebesar 1,77.  Investasi tersebut berperan menciptakan penyerapan tenaga kerja sebanyak 49.158 orang per tahun, dengan elastisitas penyerapan tenaga kerja sebesar 0,98.  Import content di sektor bersangkutan sebesar 5,92% dengan nilai sebesar Rp 993.934.000.000,- per tahun. Peran investasi di sektor industri makanan berkontribusi besar terhadap pendapatan nasional dan ketenagakerjaan, yang berimplikasi cukup baik pada ketahanan nasional. Namun demikian, import content yang relatif cukup besar bila tidak dicermati dapat memperlemah ketahanan nasional.

Abstract

To study the effect of deterpenation process on the medicinal quality of nutmeg oil (Myristica fragrans Houtt), the alcoholic extraction as well as the chomatographic separation technique of deterpenationwas employed on some crude nutmeg oil.Result of the experiment concluded that either the alcoholic extration or the chromatograpic separation technique of deterpenation caused a down grade of the medicinal quality of nutmeg oil due to an increase in the level of myristicin concentration. The former technique gave a complete removal of monoterpene hydocarbon and the latter gave only partial removal.

Abstract

A study on the effects of distillation time and seed crushing on the yield and physico-chemical properties of cumin oil has been conducted. Two treatments were given to cumin seed i.e.(a) remain whole, and (b) crushed (using blender). The seeds were distilled using cohobation methods for 3,5 and 7 hours. The yield of whole seeds were 1.90; 2.10 and 2.23% for each distillation time, while those of crushed seeds were 2.18; 2.25 and 2.43% respectively. The evaporation residues of both oils were increased from ca. 0.18% (3 hrs. distillation) to 2.23% (7 hrs distillation). an from ca. 0.20% (3 hrs. distillation) to 0.26% (7 hrs distillation). The highest cuminaldehyde content was obtained from 3 hrs. distillation (5.99%) and the lowest was those of 7 hrs. distillation (45.14%).

Abstract

A study to analyse for equilibrium moinsture content, sorption-isotherm and economic analysis of ginger powder processing (zingiber officinalle Rosc) production has been conducted. the study was aimed at designing adsorption and desorption model of ginger powder by investigating its equilibrium moisture content conducted at 30 C and 40 C, relative humifily (Rh)level of 11.3, 32.4, 51.4, 63.5, and 75.0% for adsorption model and 11.2, 31.8, 48.5, 61.4 and 75.8% for desorption model. Four models of smith, henderson, caurie and bradley were emploved and modified to investigate a model which appropriate for ginger powder composition. before resulting the models and curves. it was initially calculated some constant. the modification of smith model showed the best result for adsorption condition. Financial analysis was conducted to evaluated the financial viability of ginger powder processing. the financial analysis of ginger production of 500 kg per day consits of some parameter e.g IRR (internal rate return) was 28.53%, NPV (net present value) was Rp. 204.252.000.-, net revenue was Rp. 252.000.000,- and PBB (pay back period) was 3.5 years. It can be concluded that ginger powder production was viable to be set up.
