Abstract

For long time vegetables were thought only as sources of several vitamins; however, it has been shown that vegetables contain other component, which is also important for maintaining body's health, i.e., dietary fiber. Dietary fiber is a group of polysaccharides oan other polymers, which cannot be digested by upper gastro-intestinal system of human. Dietary fiber can be grouped as soluble and insoluble dietary fiber, showing in different physiological effect. Soluble dietary fiber (SDF) is effective in preventing cardiovascular disease, while insoluble dietary fiber (IDF) can prevent the development of colon cancer, diverticulosis as well as obesity.Local vegetables found to contain high SDF (higher than 3,06% db) are: watercress, green bean, carrot, eggplant, lettuce, broccoli, spinach, string bean, and aubergine; while which contain high IDF (higher than 40,60% db) are: winged bean, watercress, chinese leaves, katuk leaves, lettuce, green bean, broccoli, carrot and spinach. Cooking (i.e. boiling, steaming and pan frying) decrease the IDF content of vegetables, while their SDF content is not affected by cooking treatments.

Abstract

Post harvest damage of horticulture commodity in Indonesia has reached 30 to 40%. This research is aimed at extending the storing period of cavendish banana in order to extend the market range, while still enabling to maintain the quality of fresh preserved banana as required by consumers. One of the ways to do so is by using combines adsorbant as to control the air of the fruit surrounding.The type of adsorbant used is as follows : 1,2 and 3% of KMn04 ; 0,5, 1 and 1,5% of iron powder, and 3% of active carbon. The experiment was conducted in completed randomized design, by 10 factors of combined and concentrate adsorbant, and by 6 factors of storing time. The parameters being analyzed includes texture intensity, starch rate, total acid rate, total glucose rate, water rate and reduced glucose rate.The statistics test results of 10 treatments of combines adsorbant KMn04, iron powder, active carbon which were(1%, 0,5%, 3%), (1%, 1%, 3%), (1%, 1,5%,3%), (2%, 0,5%, 3%), (2%, 1%, 3%), (2%, 1.5%, 3%) (3%, 0,5%, 3%), (3%, 1%, 3%) ( 3%, 1,5%, 3%), suggested that the combined adsorbant (2%, 1,5%, 3%) at 15°C storing temperature is the best. This treatment is the best because it has the highest substances rate up to 72.36% db; relatively small texture change, total acid rate, total glucose rate, water rate and the lowest reduced glucose rate of 3.531% db which is more likely to extend the storing period of cavendish banana for approximately six weeks.Key Words : horticulture, cavendish, adsorbant, texture, storing period.

Abstract

Soybean is a strategic commodity which is used as a raw material for food processing and consumed by most of Indonesian people. National demand cannot be covered by local production, due to imported one. This research indicated that soybean harvested area was influenced by local soybean real price, maize real price and last year harvested area. Soybean productivity was influenced by rainfall, maize real price and last year productivity. Local soybean price was influenced by soybean real price at producer level, imported soybean real price, quantity of imported soybean, productivity and last year soybean real price. Soybean real price at producer level was influenced by soybean production, imported soybean quantity, soybean consumption, BULOG monopoly and last year real price at producer level. Soybean import quantity was influenced by production and consumption. Imported soybean price was influenced by international price, exchange rates, import tariff, and last year import price. Combination policy of increase the soybean price and import tariff 20% would stimulate the producer to increase harvested area and production. Strategy to increase competitiveness and national soybean production are through productivity improvement and extended planting area programs. The priority to increase the production is to improve productivity and apply suitable technology. Extension of planting area to better region is conducted to increase cropping index. To anticipate trading liberalization negative effect to farmers’ welfare, protection policy by the government is still needed to control international price fluctuation and to strengthen local soybean competitiveness.

Abstract

The measurement of sucrose content of sugar cane is usually carried out by using polarimeter and Brix Wager scale. These two apparatus are operated manually so that the accuracy of the measurement results is depended on the operator skill. To overcome this problem we have developed an alternative method that can measure the sucrose content more quickly and accurately than the conventional methods. This new method was carried out by using ultrasonic waves whose velocity depends on the sucrose content. Firstly, the electronic apparatus used was calibrated with 37 samples of sugar cane with various sucrose content from 4.46 % to 7.29 %. The result of this calibration was an empirical equation between the ultrasonic wave velocity V and the sucrose content R, i.e. R = 2.65 V2 - 11,95 V + 17,65 where R in % and V in km/s. Then this equation was stored as database in a computer program that will be used to calculate the sucrose content. Finally, this sucrose content measurement system was tested by using 30 samples of sugar cane. The maximum error of the measurement result was 6.4 %.

Abstract

The aim of this research was to study the variation of shelf-life values, obtained in quantifying shelf-life of biscuits among models of accelerated storage studies (ASS) from unidirectional Fick'S law. Shelf-life of biscuits is defined as the length of time of a packaged biscuits can be stored before the onset quality change appears.Four models: Heiss-Eichner (1971), Labuza (1983), Rudolph (1986) and Half Value Period or HVP model (Syarief, 1986) were evaluated. These models shared a common basic principle that they were all derived and developed from unidirectional Fick's law. Therefore, each parameter of individual model can be compared to the athers. A semi empirical approach using reaction kinetics through Arrhenius plot was used as a real shelf-life values.Quantification resulted in two categories of shelf-life values, First those which higher than expected value and second, were lower than expected.Parameter evaluation of components of Heiss-Eichner and Labuza models clearly shown less in number than components of Rudolph and HVP models. This led to a conclusion that the more sophisticated models gave higher shelf-life values as compared to the Arhenius model.
