Abstract

Artemisia cina is a medicinal plant species which produces bioactive compound potential to anti-tumor, antifungal and antibacterial medicines. This study was aimed to obtain A. cina polyploid plants through a treatment of growth regulators in shoot culture. The shoot were treated in 1; 15; 2; and 3 mg L-1 of 2,4-dichloro phenoxy acetic acid (2,4-D) combined with 1; 1.5; 2; 3 mg L-1 of Benzyladenine (BA) for 28 days. Chromosome analysis showed that the highest polyploidy percentage, 23%, was reached in the treatment of 2 mg L-1 of 2,4-D combined with 1 of BA mg L-1. The polyploidy level varied, comprising 2n=3x, 2n=4x, 2n=5x, 2n=6x, with the highest polyploidy level percentage, 28.57%, and it was attained in the tetraploid (2n=4x). Polyploid plants had larger leaves area, larger stomatal size, and higher chlorophyll content than diploid plants. However stomatal density of polyploidy plants was lower than that of in diploid plants.

Abstract

The primary cause of wilting in leafy vegetables after harvesting is high intensity of transpiration processthrough natural openings (stomata, hidatoda and lenticels). The mechanism of closing and opening of those naturalopenings is affected by the temperature of the environment. Under high external temperature, the stomata tendto open and vice versa. It is possible to diffuse water into the produce to give a vigorous effect by controlling theexternal temperature and moisture. The process is normally called crisping. The aim of this experiment was tostudy the effectiveness of crisping in order to give vigorous and freshness effects to four different leafy vegetables,namely lettuce, kangkung, leeks and chinese cabbage compared to those without crisping. The crisping processwas involving the immersion of produce in three different water temperatures (30, 40 and 50oC) combined withdifferent lengths of immersion times (1, 3, 5 and 7 minutes) and continued by immediate movement of produce tolow temperature (5±2oC) and stored for 12 hrs before placing and displaying at the show case under temperatureof 10±2oC. Produce treated as controls were provided without immersion in the warm water and stored at roomtemperature, and other was also placed at the show case. The result shows that the effectiveness of crisping dependedupon the physical structure or morphology of the respective vegetables. In general, the water temperatures of 30 and40oC and combined with the lengths of immersion time of 1-3 minutes were effective to improve the freshness andvigorousness of lettuce and leeks, while 7 minutes immersion was effective for kangkung and Chinese cabbage.

Abstract

Frying is one of fast and practical mean of cookingprocess of food using fat or oil media. The aims of theresearch were to find out, to test and to apply the model of oilabsorption in potatoes during frying. Frying temperatureswere adjusted at 140oC, 160oC and 180oC, with interval timeof analysis at 0, 30, 90, 150, 300, dan 600 seconds. Freshpotatoes were cut in cylinder shaped with diameter of 0.9 cmand 4 cm long. The result showed that the higher fryingtemperature, the higher absorption of fat during frying. Therate of fat absorption could be analogically expressed as theNewton model for cooling, to predict the absorption of fatduring frying of fresh potatoes in other temperature.

Abstract

Water loss is a main cause of deterioration because it results not only in direct quantitative losses, but also in losses in appearance (wilting and shriveling), textural quality (softening, flaccidity, limpness, loss of crispness and juiciness), and nutritional quality. Transpiration is a physical process that can be controlled by applying treatment to commodity e.g. waxes or wrapping with plastic film or by manipulating the environment. Temperature management is the most effective tool for extending the shelf life of fresh horticultural commodities. The aimed of this experiment was to study the effect of modified atmosphere packaging of polyethylene (PE) plastic on physical quality of caisim during cooling storage. For that experiment, caisim were packed into PE plastic without hole (P1), 2 holes (P2), 4 holes (P4), 6 holes (P6), and 8 holes (P8). Products as controls were provided without packed. Then, products were stored in cold storage on 0 – 5oC for 4 days. The results of this experiment shows that packaging were significantly affected the decreasing of weight, moisture content, and the value of physical quality of caisim for 4 days, in spite of colors. Packaging of polyethylene plastic without hole can delay the deterioration or change physical quality of caisim more than 4 days.

Abstract

Bali’s salacca is one of fruits which is perishable and isnot able to be stored for along time. To lengthen its shelf lifeand to prevent it from damage, this fruit can be packed inpolyethylene plastic which is known as modified atmospherepackaging (MAP).There were two objectives of this research. The firstobjective was to study respiration rate of Bali’s salacca fruitsin MAP. The second one was to study its weight loss duringstorage.This research used polyethylene plastic as packaging withthickness of 0.02, 0.05, and 0.08 mm. Storage time were 0, 2,4, 6, 8, 10, and 12 days at room temperature storage.The result showed that respiration rate expressed as O2and CO2 increased in the beginning, decreased in middle of,and increased again until the end of storage time. Duringstorage of this fruit in MAP showed lower weight loss thanthose of without packaging. It was found that the ticker theplastic used the lower weight loss of the fruit.

Abstract

Children are a gift of God which is given to be treated and maintained. Oneeffort to give attention to early childhood is the provision of a decent education tochildren, especially during the development of the child, so the child is able tomaximize its development to the optimum. an early age is an important phase inhuman development across the life span. the attention of parents to their childrenwill determine how the child in adult life. to provide educational services for earlychildhood can be started since the child is born until the age of 6 years. thegovernment has set up the organization for early childhood: first, formal channelsinclude kindergarten (TK), Raudhatul RA (RA) and kindergarten outstanding(TKLB). A second, non-formal pathways include garden Nursery (TPA), play group(KB) and a type of early childhood education Units (SPS), and the third informalchannels such as family education and the environment. This type of service devotedto early childhood is intended to prepare children to enter further education.Keywords: Early Childhood Education(ECD), Formal, Formal, Informal

Abstract

Penggunaan koagulan lateks yang tepat mampu menghasilkan karet bermutu baik. Namun, jaminan ketersediaan dan harga koagulan anjuran menyebabkan petani karet beralih menggunakan koagulan non-anjuran, sehingga dalam penelitian ini mencoba meneliti tentang karakteristik morfologi dan mutu karet yang dihasilkan oleh koagulan anjuran asam formiat dan koagulan non-anjuran asam sulfat. Hasil penelitian menunjukkan bahwa bobot basah koagulum asam formiat lebih berat dibandingkan bobot basah koagulum asam sulfat, meskipun waktu koagulasinya lebih cepat dibandingkan waktu koagulasi asam formiat.  Mutu karet yang dihasilkan oleh asam formiat berdasarkan kadar karet kering, kadar abu dan kadar zat menguapnya lebih baik dibandingkan dengan mutu karet yang dihasilkan oleh asam sulfat.Kata kunci: Koagulasi; asam formiat; asam sulfat
