Abstract

Fruit production in Indonesia has greatly increased year by year that is resulting in price fluctuation due to abundant products. The fruits possible to be rotten which decrease the sale value when the harvest time is unstable. One of the efforts for increasing the sale value of fruit is by making juice. The most important process of making juice is pasteurization. Ohmic heating pasteurization is one of pasteurization methods that can be utilized to pasteurize the juice. Thus, the juice pasteurization machine was created in particular design to pasteurize juice in small-scale. This study aims to determine the design of machine and the performance machine test, and to determine the efficiency of energy use of machine performance. Performance testing of energy efficiency of fruit juice pasteurization was carried out in an ohmic tube with a diameter of 3.55 cm and electrode spacing of 18 cm. The experiment used mango as a sample with the addition of water (2:1), the sample was pasteurized with 3 variations of electric potential included 220V, 385V, and 425V up to 800C. The highest energy efficiency up to 94%. It was obtained in voltage of 385 V with pasteurization time 130 s and the lowest energy efficiency up to 88%. It was obtained in voltage of 220 V with pasteurization time 369 s. The result showed that the ohmic-based fruit juice pasteurization machine was able to pasteurize in short time and had high efficiency.Keywords: Ohmic Heating, Efficiency, Pasteurization

Abstract

Vacuum Impregnation (VI) adalah teknik untuk memasukkan suatu larutan ke dalam media berpori melalui mekanisme hidrodinamik yang ditimbulkan oleh perubahan tekanan. Penelitian yang telah dilakukan bertujuan untuk mempelajari karakteristik perpindahan massa pada proses VI pada tekanan yang berbeda pada buah pepaya. Buah pepaya yang telah dipotong berbentuk kubus dengan ukuran 60 x 30 x 10 mm, ditempatkan dalam larutan sukrosa 30%, dan di impregnasi pada tekanan 50, 40, dan 30 mBar, serta tekanan atmosfer sebagai kontrol, selama 5, 10, 15, dan 20 menit. Data penelitian menunjukkan bahwa perlakuan VI pada buah pepaya dalam larutan sukrosa, memberikan nilai koefisien perpindahan gula yang lebih tinggi dibandingkan dengan perlakuan dehidrasi osmosis, yaitu berkisar antara 10.4–37.11/m2h pada VI dan 7.85–15.319/m2h pada dehidrasi osmosis, sedangkan untuk perpindahan massa air nilai koefisien pindah massa berkisar 12.264–15.267/m2 pada dehidrasi osmosis dan 0.612–12.317/m2 pada perlakuan impregnasi 40 dan 50 mBar, sedangkan pada perlakuan tekanan 30 mBar terjadi penambahan kandungan air dengan koefisien pindah massa air -1.732 -9.8/m2.

Abstract

Research of the effect of cooking temperature and stirring speed on the quality of brown sugar cane were processed by vacuum vertical evaporator have been done. Brown sugar cane produced from purified green cane juice. The purification was done with addition of Ca(OH)2. Pure juice cooked with cooking temperature of 60, 70, and 80 oC, and the stirring speed of 200 and 250 rpm. Brown sugar cane was analyzed for color, moisture content, ash content, sucrose, and organoleptic test (hedonic quality test for color, flavor, and texture of hardness). The results showed that the higher of cooking temperature, the better the quality of color, flavor, and hardness brown sugar cane produced. While the higher stirring speed, lower moisture content of brown sugar, so the hardness of brown sugar was better. Besides effect of cooking temperature and stirring speed, quality of brown sugar cane was affected by the quality of cane juice and juice purification process. Good quality of cane juice will produce high yield, low moisture content, high sucrose, and good color, flavor, and hardness. The best result was obtained on brown sugar cane produced by cooking temperature of 70 oC and stirring speed of 250 rpm, which was obtained yield of 8.23%, sucrose of 75.37%, hardness of 4.52 kg/cm2, bright and high color intensity of brown sugar cane.Keywords: cane sugar, vacuum evaporator, brown sugar, stirring, cooking temperature

Abstract

Lignocellulosic has promising material for bioetanol production. One of the abundant material is the stem of a Palm. Stem of palm is a plantation of palm waste which has not been utilized optimally which is contain high cellulose. Every year Indonesia produce palm stem of 300.375 ktons. This waste can be develop to produce bioetanol. However, pretreatment processes conducted some researchers still do not optmimal. This is related to the particle size and the method of pretreatment of less than optimal so that led to an overhaul of the lignin insufficient, consequently increased levels of cellulose was not significant resulting in low yield by bioetanol. Therefore, the research was implemented using the process of pretreatment method ultasonifikasi in order to produce higher pulp with nano-sized particles that will yield ethanol derived stem of palm is higher. Research methods used in this research composed of two factors, namely the concentration of NaOH and frequency ultrasonic waves that are each composed last 3 levels. The analysis conducted was the influence of the concentration of NaOH and time ultrasonikasi to increased cellulose pretreatment process using PSA, SEM and a Cheason. For the analysis of the results, data, and best treatment using ANOVA. The best treatment was obtained by combination of 9 (2 M NaOH konsentasi and sonikasi frequency 60 Hz) and lignin (19.6%) cellulose (59.49%) and hemicellulose (11.8%).Keywords: Bioethanol, pretreatment, ultrasound, stem of  palm

Abstract

Banturejo that is located in Kecamatan Ngantang, Kabupaten Malang, East Java Province, has a potential commodity in fisheries. The local resident see this potential commodity as a business opportunity by producing several kind of food products. KOPWAN Srikandi, which is women corporation, sell food products from fresh fish material. One of the products is catfish (Pangasius pangasius) floss. The problem production is the quality of fish floss which contain high level of oil content. Therefore it makes shelf life of catfish floss is relatively short. “Spinner pulling oil” is an automatic removal oil device which is equipped by centrifugal force to reduce the high level of oil content and become a solution to solve the problems on a household industries. Spinner Pulling Oil equipped with timer that able to automation and dimensions used for the design are Length x Width x Height is 60 x 45 x 52 centimeters. The driving tool with an electric motor that is used has the power ¼ HP, 2.36 A with 220 V of voltage, 50 Hz, 1400 RPM (1 phase motor) and 200 watt so it can move the material basket with a capacity of 10 kg at a speed of 1076 RPM. Performance testing of spinner was carried out to determine the machine performance with trial to the machine and by doing the test of the oil content of sample after spinning. The sample of catfish floss was threatened with the difference time duration included 0, 2, 4, 6, 8 and 10 minutes. In this study, the time optimal and the power consumption of device was being analyzed.
