Dental fluorosis (DF) is an endemic disease caused by excessive fluoride exposure during childhood. Previous studies mainly focused on the acid resistance of fluorotic enamel and failed to reach a consensus on the topic of the caries susceptibility of DF patients. In this review, we discuss the role of DF classification in assessing this susceptibility and follow the “four factors theory” in weighing the pros and cons of DF classification in terms of host factor (dental enamel and saliva), food factor, bacteria factor, and DF treatment factor. From our analysis, we find that susceptibility is possibly determined by various factors such as the extent of structural and chemical changes in fluorotic enamel, eating habits, fluoride levels in diets and in the oral cavity, changes in quantity and quality of saliva, and/or oral hygiene. Thus, a universal conclusion regarding caries susceptibility might not exist, instead depending on each individual’s situation.

Shallots (Allium ascalonicum L.) have a short shelf life because these tubers can experience decay and premature germination. Therefore, innovation is needed in shallot processing, one of which is by processing shallots into pasta products. This research conducted the making of onion paste with the addition of vegetable oil to improve the quality of the paste. The purpose of this study was to examine the effect of vegetable oil concentration treatment on shelf life and quality of shallot paste and to determine the level of preference for the panelists to shallot paste by organoleptic test. This study used a completely randomized design (CRD), namely one treatment factor with the addition of vegetable oil concentrations of 30%, 25%, and 20%. The data were analyzed using variance, if the results were significantly different, then it was further tested with DMRT with a significant level of 5%. The results showed that the concentration of vegetable oil on shelf life and quality of shallot paste were not significantly different so that the addition of vegetable oil concentration had no effect on shelf life and quality of shallot paste. Panelists preferred color and taste parameters of shallot paste with the addition of 30% vegetable oil. Meanwhile, for the pasta aroma that the panelists like, the paste with the addition of 25% and 20% vegetable oil.

Indonesia is one of the largest coffee producing and exporting countries in the world. Most of the production is robusta variety. Coffee is the fourth largest foreign exchange earner for Indonesia after palm oil, rubber and cocoa and is a source of income for the community. Coffee can be developed in a generative (seed) and vegetative way, including using cuttings. Efforts to accelerate the formation of roots in cuttings can be done by using natural growth regulators, one of which is shallots which contain auxins. The purpose of this study was to examine the effect of shallot extract on the growth of robusta coffee cuttings (Coffea canephora). This research was conducted from December 2019 to February 2020 at Campus II, Batanghari University (Pijoan). The design used in this study was a completely randomized design (CRD) with one treatment factor, namely shallot extract including; .k0 (without giving onion extract), k1 (250 g of shallots in 1 liter of distilled water), k2 (500 g of shallots in 1 liter of distilled water), k3 (750 g of shallots in 1 liter of distilled water), and k4 (1000 g of shallots in 1 liter of distilled water). Each stage of the experiment was repeated 3 times, so that there were 15 experimental plots, for each experiment there were 10 cuttings with a total of 150 cuttings. The observed data were analyzed using analysis of variance followed by the DNMRT test at α 5%. From the immersion treatment in 750 g of shallot extract in 1 liter of distilled water (k3), there was an increase in the percentage of live cuttings 47.37%, the percentage of shoots and roots growth of 83.51%, 106.06% of shoot length, and 98.03% of roots. , and the root dry weight of 225.27% compared without giving onion extract (k0).
