Abstract

The experiment is aimed to develop a model to control the air temperature of drying chamber during drying of Chilli using Logical Fuzzy Control (LFC).  The temperature characteristic of three dryer subsystem, namely the drying chamber, the commodity (chilli), and the heater, is predicted by a mathematical models based on heat and mass balances.  Mathematical model obtained were then solved by numerical analysis using a Finite Different Euler Method, followed by simultaneous solution by a method of Gauss Jordan.  Borland Delphi 5.0 program and Celeron 566 MHz and RAM 256 MB processor was used to make a simulation program. The control of drying chamber temperature is carried out by adjustment of the energy given to the heater.  The degree of deviation to the set temperature of the drying chamber and the corrected value were then used as inputs to LFC.  As an output of the LFC is the amount of energy supplied to the heater.  The input was divided into three groups of set i.e.  3.5 and 7.  The function of the input element is a symmetrical triangle function, while the one of the output element is a fuzzy singletone. It was found that the determination value (R2) of the drying chamber, the commodity and the heater were 0.65, 0.62 and 0.67 respectively with the respective RMSE value of 2.2, 2.8 and 2.3.  A set of input of 7 was found to give the best LFC as compared with other sets of input. The control of drying chamber temperature using LFC for drying of chilli is best conducted in the range of set point of 45 – 55 oC.  At a temperature of 45 oC for 72 hours, the moisture content of the chilli was reduced from about 80 % to 32.9 % wet basis with an consumption of energy of 547.02 kWh.   Keywords: Simulation, Logical Fuzzy Control, Finite Different Method, Gauss Jordan Method

Abstract

Edible film is commonly used in the preservation of fresh and minimally processed fruits. The suitability to be used for such purpose mainly determined by its physical characteristics like transmission properties, particularly its permeability to water vapour, oxygen and carbon dioxide. The research was conducted to determine the transmission properties of the edible film made up of low metoxyl pectins (LMP) as a primary component combined with stearic acid at a level of 0.25% v/v. Particular study was made to determine the permeability of the film towards water vapour, oxygen and carbon dioxide at various ranges of temperatures (5 to 28oC) and relative humidities (0 to 80%) examined on the film with thicknesses of 20 – 50 µm. The results indicated that the permeability coefficients of the film varied with transmitted substances. The values were 12.89 – 19.45 g.mm/ (m2.day.kPa) for water vapour, 3.26 – 28 mL.mm/(m2.day.kPa) for oxygen and 149 – 129 mL.mm/(m2.day.kPa) for carbon dioxide.Key words: LMP-based edible film, permeability coefficients

Abstract

Biodiesel is an alternative fuel with a fatty acid ester composition made from raw vegetable oils/animal that has characteristics similar to diesel oil. High quality biodiesel fuel from oil/fat had been processed by two-stage supercritical metanol method which consisted of the hydrolysis process by mixing oil and water in sub-critical conditions that generated free fatty acids and glycerol, followed by esterification process that mixed free fatty acids with methanol in supercritical methanol conditions.  In this research, hydrolysis of frying oil at sub-critical conditions had been conducted in various conditions. The conditions were the ration of oil to water and hydrolysis time in the reactor chamber at sub-critical condition. Materials used in this research were commercial frying cooking oil and bottled water.  The purpose of this study was to find out the effect of hydrolysis at sub-critical condition on free fatty acids content generated in the production of biodiesel using super critical methanol.  The results showed that there was an increasing percentage of ALB in the hydrolysis reaction with sub-critical water conditions. The highest and significant ALB was 67.10% that obtained in ratio of water to oil 25:75 and holding time of 20 minutes. Fatty acid produced in super-critical reactor was solid at room temperature and the behavior of this product still required a thermal analysis for designing exhausting pipe from the reactor in order to prevent blockage.Keywords: Biodiesel, hydrolysis, sub-critical, free fatty acids

Abstract

Tahu merupakan makanan yang diolah dari kedelai yang melalui proses fermentasi. Limbah cair tahu memiliki kandungan BOD, COD, dan TSS yang tinggi, apabila langsung di buang ke perairan akan menyebabkan pencemaran dalam perairan tersebut. Arang aktif dapat dipakai sebagai adsorben untuk mengurangi kandungan dalam limbah cair tahu. Arang dari limbah tongkol jagung diaktivasi menggunakan larutan Asam Sulfat (H2SO4) 5 M dan 7 M. Arang aktif direndam dalam limbah cair tahu selama 90 menit, 120 menit, 150 menit, dan 180 menit. Parameter yang diukur adalah BOD, COD, dan TSS. Kondisi yang paling dalam menurunkan nilai BOD, COD, dan TSS adalah arang aktif 7 M dengan waktu perendaman selama 180 menit. Arang aktif tersebut menurunkan nilai BOD sebesar 37,97%, COD sebesar 32,83%, dan TSS sebesar 27,22%.

Abstract

Meningkatnya jumlah sampah kantong plastik di Indonesia mengharuskan produsen makanan beralih ke plastik yang lebih ramah lingkungan seperti bioplastik. Bioplastik merupakan salah satu jenis plastik yang terbuat dari polisakarida yang berasal dari tumbuhan seperti selulosa dan pati. Salah satunya adalah pati jagung yang memiliki kandungan amilosa cukup tinggi dan mudah terurai di alam. Pada penelitian ini digunakan tepung jagung sebagai bahan baku pembuatan film plastik biodegradable. Terdapat dua faktor perlakuan yaitu konsentrasi penambahan CMC dan suhu pengeringan. Setiap perlakuan terdiri dari 3 taraf yaitu 0,5% (b/v) 1% (b/v), dan 1,5% (b/v) serta suhu pengeringan yaitu 50áµ’C, 70áµ’C dan 90áµ’C yang dikeringkan selama 3 jam. Untuk memperbaiki fleksibilitas plastik ditambahkan gliserol sebesar 2% (v/v). Tujuan dari penelitian ini adalah untuk mengetahui pengaruh konsentrasi cmc dan suhu pengeringan terhadap sifat mekanik dan sifat biodegradasi, serta melakukan pengujian fisik seperti pengukuran densitas dan uji ketahanan plastik terhadap air melalui uji penggembungan. Adapun hasil dari penelitian ini menunjukkan bahwa semakin tinggi suhu pengeringan akan menurunkan nilai kuat tarik dan persen pemanjangan. Banyaknya konsentrasi cmc akan meningkatkan nilai kuat tarik dan menurunkan persen pemanjangan. Film plastik akan semakin cepat terdegradasi dengan semakin banyak konsentrasi cmc dan semakin tinggi suhu pengeringan akan semakin lama terdegradasi. Perlakuan terbaik pada konsentrasi CMC 1% dan suhu pengeringan 70áµ’C.Kata kunci: Biodegradasi, CMC, Kuat Tarik, Suhu Pengeringan
