Abstract

Hypoglycemic and hypolidemic properties of Edible podded peas (Pisium sativum LINN) and Soy bean (Glycine max MERR) were evaluated in alloxan-induced diabetic rats. The objectives of this research were to investigate the effects of these legumes on serum glucose, total cholesterol and triacyl glycerol in alloxan-induced diabetic rats. Thirty male Sprague-Dawley (SD) rats (250-300 g) were provided and divided into three groups of ten rats. They were diabetic induced by twice intramuscular injection of alloxan (80 mg/Kg of body weight), then fed with three different diets i.e. Standard (ST), (2) Edible Podded peas (EP) and Soybean (SB) for 28 days. The legumes provided 20 % calorie of total duet calorie. Concentration of serum glucose, total cholesterol and tracyl glycerol were measured before injection and diet intervention (0 day and day 17th) and were monitored in the middle and at the end of diet intervention (day 31st and 45th). It was found that alloxan injection increased serum glucose concentration from 63.5 mg/dL to 281.4 mg/dL, total cholesterol and triacyl glycerol concentration increased from 90.7 mg/dL to 136.6 mg/dL and from 108 mg/dL to 147.5 mg/dL, respectively. In 28 days of diet intervention, EP and SB diets decreased the serum glucose concentration by 145.5 mg/dL (67%) and 142.1 mg/dL (65%), respectively, compared to 125.3 mg/dL (57%) in the ST diet. Total cholesterol decreased by 31% and 27% for EP and SB groups. respectively but only 17% for ST rats. Intervention of the diets also decreased concentration of triacyl glycerol by 9% and 5% for EP and SB diets, respectivelym but increased by 6% for standard (ST) diet.

Abstract

The utilization of shallow groundwater well to support cropping pattern in dry land area should be directed to increase land and water productivities through proper irrigation management and effective operation of groundwater irrigation pump. By the concept that a certain plant needs a certain amount of transpired water through it's leaves to produce 1 kg dry product during it's production cycle, an attempt is done to determine technical and economic aspects of the groundwater irrigation system to utilize water and energy efficiently by improving the conjunctive use of rainfall and groundwater irrigation in dry land area. A set of centrifugal pump (ɸ 2") was used to lift water from the shallow groundwater well at total head of 22 m (Suction head = 12 m and delivery head = 10 m) and was used to irrigate maize, peanut and onion crops. The result obtained indicateds that the introduced technology is suitable to be applied at farm level. In order to reduce operational cost of pump, simulation was done to determine the most appropriate planting achedule using computer simulation model. By taking planting schedule back approximately 2 weeks reducing annual irrigation requirement of 500 to 600 m3/ha and reduce annual operation pump of 66.5 hour/ha/year. Advanced analysis using economic feasibility analysis indicates technology introduced suitable to applied with B/C ratio = 1.25 (maize), 1,83 (peanut) and 2,36 (onion).

Abstract

Pumpkin flour has high β-carotene, therefore, can be added to the noodle to alleviate vitamin A deficiency. Deterioration of β-carotene may take place during drying, proper control of the process to minimize the deterioration is necessary. The objective of the research was to study the β-carotene deterioration during drying process of the noodle and the physico-chemical properties of the cassava noodle that was enriched by pumpkin flour. The enrichment of the cassava flour was made by adding pumpkin flour various proportions 0, 5, 10 and 15 %. Noodle was sun dried for 8 hours, in cabinet dryer at 60ºC for 3 hours and in a two step cabinet dryer (60ºC for 2 hours followed by drying at 55ºC for 2 hours. The result showed that sun drying cause the greatest deterioration of β-carotene (46.24%). However, enrichment of pumpkin flour can improved the color, protein and β-carotene content of the noodle.

Abstract

To operate machines during the producing wet-noodle sheets processes involve both crews' hands and physical activities. The constructed structures for such machines which are not suitable for the operators's physical anthropometry may ultimately affect the operators' performances. Accordingly, declining in production quantities and qualities are unsurprising. Three stages are involved in designing and construction of such machines based on the above approaches. Namely identifying a set of operators' associated needs (which are gathered through questionaires), secondly is developing the ergonomics machine concept through FAST diagram and the last stage is analyzing the machines' overall expected value and performances. These design stages are performed on the main machine structure, the mixed blend basin, the milled paste container and on the handle grip to rotate the milling device. Studies indicated that machines constructed through these methods produced increamental of performance by 2.56% and value by 3.72 % respectively.

Abstract

In the terms of precision farming system, this research was carried out in order to develop a trajectory path control method for the autonomous tractor when approaching a target. Firstly, open loop control was considered to design a trajectory control algorithm directly, definitely and simply structure. A proposed trajectory control algorithm called parallel parking theory was developed as non-linear state equation within non-holonomic constraint. To stabilize non-linear controlled, the algorithm was derived using the state feedback linerization technique. The vehicle posture can be expressed into position, direction angle and steering angle. In a front-wheel steering vehicle, two controlling inputs, running speed and steering vehicle, two controlling inputs, running speed and steering angle. Due to the running speed is difficult to control accurately, thus only the steering angle was controlled. In order to achieve the research objective, research work was carried out to compare the performance developed control algorithm between feedback and open-loop control system. A twenty-nine Ps computer-controlled tractor with four-wheel steering and four-wheel drive was used in this research ecperiment. For local based positioning method, fan beam laser sensor,fiber optic gyro sensor and incremental type rotary encoder were installed properly on the vehicle. The experimental results showed that after modifying of the developed algorithm into a feedback control form by correcting vehicle direction angle and lateral moving distance had improved its accuracy varied up to about 95%.

Abstract

Experiments were performed to optimize the process of smoke powder production using liquid smoke of coconut shell as raw material and rice powder as a model system for filler of smoke posder. The liquid smoke was produced by pyrolization method and the purification of the liquid smoke was done by redistillation method. The redistilled liquid smoke was diluted with varied water and mixed with some ratio of rice powder. The sensories of smoke powder was evaluated for ador, taste and overall, and data were optimized using Response Surface Methodology.The result of optimization process on the production of smoke powder indicated that the optimum temperature for redistillation process were 160ºC, the ratio of redistilled liquid smoke and rice powser was 2.5 ml/ 50 gram, and the concentration of the liquid smoke was 15.1%. The confirmation of the optimization value indicated that smoke powder was acceptable for consumer.
