Abstract

Learning difficulty students at the Nahdlatul Ulama Institute of Technology and Science Pasuruan in first semester for academic on year 2018/2019 which are marked by midterm scores in general Biology courses for human digestive system meterial that is deficient. Learning Difficulty student can lead to their lack of achievement in this course. This research was conducted to find out the factors of learning difficulty both internal and external by the students and the expectation is to be able to provide further input as an effort to resolve the difficulty learning to improve their learning achievement. This research is a qualitative descriptive study that aims to determine the internal and external factors that induces difficulty student Learning in General Biology courses in human digestive system material. The study used a descriptive design, tests, questionnaires and interviews to receive data. The research subjects are 32 students are from Biology, Mathematics, Physics and Agricultural Product Technology major. Based on the results of the study for the internal factors that cause their difficulty for Learning are study habits and ability material comprehension are still lacking as much as 59.37%, while the external factors are the lack of learning support tools as much as 59.37% and the condition of the house environment and around it as much as 50%.

Abstract

One of the potential agricultural products from Pasinan Village, Lekok sub-district, Pasuruan, East Java Province is Kawista Fruit. Residents of Pasinan used it for consumption, both raw and ripe. The large consumption of this fruit was caused an abundance of fruit peel. Based on the results of phytochemical analysis, the extract of kawista fruit peel contains saponins, tannins, alkaloids, flavonoids, and terpenoids. Another income source of Pasinan residents comes from marine resources, that can be served in fresh fish, dried fish and other processed fish is susceptible to contaminated by microorganisms such as Salmonella sp. Salmonella sp. is pathogenic microbe lives on intestines of animals and humans. Purposes of this study are to determine the antibacterial activity of kawista rind extract on the growth of Salmonella sp. in-vitro and to determine the concentration of Kawista peel extract which is effective for inhibiting the growth of Salmonella sp using the paper disc diffusion method. The results of this study, the diameter of the inhibitory zone for the growth of Salmonella sp. using variables concentrations of kawista rind extract at 12.5%; 25%; 50%; 75%; 100%, with negative control are distilled water and methanol and positive control is tetracycline. At a concentration of 100% extract, the diameter of the bacterial inhibition test was the largest and significantly different from another treatment group at concentrations of 12.5%; 25%; 50%; 75%. However, the 100% extract showed a smaller inhibitory zone than the tetracycline treatment group, but not significantly different. Based on the results of this study, that can be concluded that kawista peel extract is effective for inhibiting the growth of Salmonella sp. Kawista peel extract at a concentration of 100% is most effective for inhibiting the growth of Salmonella sp and shows results that are not significantly different from tetracycline.
