Rice plant is very important staple food and has been the main staple food for half of people in the world. Rice is the main commodity and food support in Indonesia. Many efforts to increase rice productivity face some obstacles, such as environmental factor and place. Water supply becomes the main problem in rice planting. Rice plant needs different volume of water for each phase of growing. The research goal is to find the effect of lacking water towards the stomata index, the length of root, and the height of the rice plant of IR64 variety and Ciherang variety. The result of the research concludes that IR64 variety has lower stomata index than Ciherang variety does. IR64 variety has low stomata index because IR64 variety belongs to indica variety that has low transpiration so that it can be planted in dry area. The length of root of IR64 variety is longer than Ciherang variety which supports the variety to be planted in dry area. IR64 variety is 83-88 cm lower than Ciherang variety.Keywordsâ€”: stomata index, length of root, height of the plant, rice variety

Abstractâ€” Plant germination is the beginning of a new individual's growth marked by the appearance of a radicle at the seed testa. This research aims to determine the effect of long immersion towards germination and growth of King Palm. This study used an experimental method with Randomized Block Design (RBD) with 4 treatments and 4 repetitions. Those treatments were treatment of P0 (control), P1 (immersion for 24 hours), P2 (immersion for 48 hours) and P3 (immersion for 72 hours). The data obtained was analyzed by variance analysis and continued with BNT test. Based on observations, King Palm seed germination is hypogeal, because cotyledons (keeping seeds) remain in the soil. King palm seeds with immersion treatment do not significantly affect germination. Likewise, immersion time does not significantly affect the height of shoots aged 55 days after seedling. The treatment of immersion time for King Palm seeds significantly affected the root length at the age of 55 days after seedling. After the BNT test, the effect of immersion towards the root length showed that 48 hours of immersion treatment had the best effect. The 48-hour immersion treatment for the King Palm plant nursery is recommended to be done by ornamental plant farmers and ornamental plant breeders to accelerate the growth process.Keywordsâ€”: King's Palm, Germination, Growth, Hypogeal.

Indonesia is the third largest coffee producing nation in the world after Brazil and Vietnam. The types and the characteristics of Indonesian coffee are different in each area but the main important factor of consumer acceptance depends on its bitterness level. Chlorogenic acid lactone is a compounds that play an important role as contributor to the coffee bitterness that are formed during the roasting process of coffee bean because of its precursor chlorogenic acid. Chlorogenic acid is commonly found in many plants. One of them can be found in coffee with high concentration. Chlorogenic acid lactone (bitter compound) can be hydrolyzed to chlorogenic acid (non-bitter compound) using hog liver esterase and chlorogenate esterase.Â This study aimed to analyze the use of these enzymes to decrease the level of bitterness in coffee. The results indicated that HLE and chlorogenate esterase effectively hydrolyzed chlorogenic acid lactones in coffee.Â Based on the sensory test, coffee extracts treated with enzymes were less bitter than the untreated coffee extracts. If it was associated with Indonesian local coffee then the method can be done with chlorogenate esterase that was in accordance with the legal guarantee of halal product.

Hypertriglyceridemia is one of the risk factors for cardiovascular disease and acute pancreatitis (Pejic and Lee, 2006; Brahm and Hegele, 2013; Afari et al., 2015). One way to treat it by using the apple vinegar (Malus sylvestris Mill) of manalagi varieties which contained high antioxidants and acetic acid as well as more durable than the fresh fruit. The study aimed to know the effect of the Apple vinegar of manalagi varieties (Malus sylvestris Mill) to blood triglyceride levels of white male rats (Rattus norvegicus) wistar strain with high-fat diet and induced by alloxan. The study used the post test only control group design, with 24 rats samples which were divided into three groups. The negative control group (K0) only received standard diet for 24 days, the positive control group (K1) received a high-fat diet for 7 days and induced by alloxan with doses of 90 mg/kgBW of rats, and treatment group (K2) was given a high-fat diet for 7 days, induced by alloxan and received the apple vinegar (Malus sylvestris Mill) of manalagi varieties with a dose of 0,27 ml/100 g BW of rats for 14 days. The results by using one way ANOVA showed the significance value of the data p = 0,974 (p>0,05) so that there is no significant difference of the mean of blood triglycerides levels between K0, K1 and K2. This study concluded that apple vinegar (Malus sylvestris Mill) of manalagi varieties can not significantly lower the blood triglyceride levels of white male rats (Rattus norvegicus) wistar strain with high-fat diet and induced by alloxan. Further study about apple vinegar of manalagi varieties is required to define its effects.

Dyslipidemia is an abnormal lipid metabolism which may cause fat degeneration on hepatocytes cells and elevated triglyceride serum level. Dyslipidemia can be prevented by the consumption of high antioxidant food. Noni(Morinda citrifolia) contains many antioxidant such as flavanoid, kuersetin, tannin, and saponin, which are able to prohibit the elevation of ROS.This research is aimed to find out the effect of noni(Morinda citrifolia) extract in reducing the number of hepatocyteâ€™s cells with fat degeneration and decreasing the triglyceride level which is elevated due to high cholesterol diet induction.In this study white rats divided randomly into 4 groups, control group (K-), high cholesterol diet induced group (K+), high cholesterol diet induced with 100 mg/Kg BW noni extract group (P1), high cholesterol diet induced with 200 mg/Kg BW noni extract group (P2). The result shows that noni Â extract with dose 100 mg/Kg BW andÂ 200 mg/Kg BWcan reduce the number of hepatocytes cells with fat degeneration (p= 0,026 and p=0,027) and decrease the level of triglyceride serum (p=0,036 and p=0,010).The conclusion is noni extract with dose 100 mg/KgBW reduces effectively Â the number of hepatocyteâ€™s cells with fat degeneration and decreases the level of triglyceride serum which increase because of high cholesterol diet.Â
