The growth of Matic-Motorcycle in Indonesia is increased steeply lately. According to Assosiasion of Indonesian Motorcycle Industry, AISI the sales of matic motorcycle have achieved 75,49% (3,639,000) of the wholesaler 4,821,000. In fact, motorcycle users do not realize that automatic motorcycle’s characteristics especially braking distance are different with those of non-automatic motorcycles. The different way of riding can cause uncontrolled vehicles during braking, when promptly change speed either faster or slower. Stopping sight distance is the distance needed by riders in order to stop their moving vehicles after seeing the obstacles in the front. This research is seeking to know the behavior of motorcycle users and stopping sight distance that is ideal for the users of automatic motorcycles. Multi linear Regression model is made to find out the relationship between stopping sight distance and other variables such as speed, machine capacity, type of brakes etc. From this model, it can be derived the ideal stopping sight distance which is affected by speed, machine capacity, type of front brakes.

This study aims to find factors influencing students to do speeding in Yogyakarta Special Region. 179 respondents filled in on-line and off-line questionnaires to determine options or probabilities of speeding up on a variety of different road / environmental conditions. Cross tab tests and ordered logistic regression are adopted to analyze influencing factors (both internal and external). 3 of 18 predictor variables do not affect speeding behavior, and those are driving experience, road separator, and speed limit signs. While the age, education, and police presence are negatively correlated with speeding behavior, it means that the older, and the higher a person's education and the presence of police, people tend not to have speeding behavior. The other research result is the level order of the influencing factor of speeding (predictor variables).
Penelitian ini bertujuan menemukan faktor – faktor yang mempengaruhi pelajar dan mahasiswa melakukan ‘speeding’ atau ngebut di Daerah Istimewa Yogyakarta.

Driving at high speed has negative consequences, namely, the high number of accidents. Several factors have been considered as causes of the increasing severity of victims of traffic accidents, such as a human, vehicle, and environmental factors. The risky driving behavior factor is a factor that needs to be considered in traffic safety studies. This study aims to determine the probability model of speeding behavior based on several driver characteristics and their relationship to accident involvement. This study used a binary logistic regression method to determine the probability of driving behavior exceeding the speed limit and accident involvement. The results showed that the younger a person is, the higher the probability of breaking the maximum speed limit. Furthermore, driving experience also shows a similar trend, where the longer the driving experience of someone, the less likely it is to be involved in an accident. Directions for further research are also presented.

Capparis spinosa (Capparidacea), is one of the most used medicinal plants worldwide. It is used for the treatment of various diseases because of its biological and pharmacological effect, such as antioxidant, anticancer, antihypertensive, antidiabetic and antibacterial. Phytochemical analysis of the plant showed that it is a rich source of bioactive constituents, including alkaloids, glucosinolates, tocopherols, carotenoids and polyphenols, which have led to C. spinosa being considered as a promising medicinal plant. Our study aims to detail the chemical profiles of the present bioactive responsible for the pharmacological effects of C. spinosa; it also aims to experimentally demonstrate the presence of polyphenols in different parts of the plant as well as their antimicrobial effects. For this, we used methanolic and aqueous extracts of the different parts of the plant picked in Beni Aziz in the Sétif region (North-east of Algeria). The extracts subjected to TLC and HPLC showed that they were rich in flavonoids and phenolic acids. This led to find that rutin was the most dominant compound in most of our extracts. On the other hand, the antimicrobial effect was tested by the disk diffusion method on three bacterial strains: E. coli, P. aeruginosa and S. aureus and two fungi: C. albicans and A. flavus. Candida albicans’s antifungal effect of our extracts was absent. While the same extracts showed a slight inhibitory activity against Aspergillus flavus. As for the antibacterial effect, it exists only for the methanolic extract of the twigs against Staphylococcus aureus. While the other extracts only showed a slight inhibitory activity against the same strain. The other strains of bacteria were resistant to all extracts at any used concentration.
