Abstract

Culex sp. is a vector of filariasis. Vector control mostly uses chemical insecticides which have a negative impact. Buas-buas plants (Premna serratifolia L.) are one of the plants that have the potential as an alternative to the use of chemical insecticides that have been widely used (as botanical insecticides). Buas-buas leaves (Premna serratifolia L.) contain alkaloids, flavonoids, saponins, and tannins. This study aimed to test the toxicity of the purified extract of buas-buas leaf (Lethal concentration 50) on the mortality of Culex sp. larvae with an exposure time of 24 hours. Serial concentrations of purified extract used were 850, 1350, 1850, 2350, and 2850 ppm with four repetitions. Each treatment used 20 Culex sp. late three to early four instars. Toxicity testing of Culex sp. gives an LC50 result of 1799.77 ppm.. Kata Kunci: Culex sp.; Premna serratifolia L. ; Terpurifikasi; Toksisitas

Abstract

Water is a natural resource which is needed for his life by all sentient beings is therefore important to know the quality of the water before consumption. The condition and texture of soil can affect the quality of the water. In district of Tegalsari Banyuwangi Regency that has a textured ground clay loam and loam water murky conditions, smelling the salty taste while in other regions the same in the sandy loam textured soil condition the water crystal clear, odorless and not felt. This research was conducted to find out the difference in the quality of biology, chemistry and physics there is ground water well textured clay loam, loam and sandy loam. Water quality test using 3 parameters i.e. biological parameter using the method of the test chemical, MPN includes the measurement of pH, and DO, test of physics include the measurement of TDS and organoleptic color, smell and taste. Research results based on biological and chemical parameters showed that water wells on the land of textured clay loam, loam and sandy loam worthy for consumption, while based on physical parameters (TDS) water well on clay loam textured soil proved to be not worth value consumed with TDS > 500 mg/l. In organoleptik water wells are fit to be consumed is water wells on the land of textured sandy loam because the water is colorless, odorless and tasteless No. The entire research results have been adjusted to PERMENKES RI No. 492/MENKES/PER/IV/2010.

Abstract

Field Experience Practice Program or Program Praktik Pengalaman Lapangan (PPL) is a mandatory program to be followed by FKIP students of the University of Jember. As a field supervisor lecturer, in order to improve the quality and effectiveness of PPL in Junior High School 9 of Jember, I launched integrated PPL program with Lesson Study (LS). Junior High School 9 of Jember, as a partner in the development of the LS school in Jember by FKIP UNEJ, providing full support to the implementation of LS-based PPL. The support not only the license to undergo LS based PPL, but also school provide policies that encourage teachers to officials actively involved in the implementation of integrated LS-based PPL. This implementation is expected to enhance the effectiveness of the implementation of the PPL so as to improve the teaching skills of students (teacher trainee). Teaching skills were measured using two instruments with two different focus. The first is the student learning observation instrument (student-focused) and the second is an assessment instrument for teaching practices (focusing on the actions of the teacher trainee). From four teacher trainee of Biology Education FKIP UNEJ who had the opportunity to practice LS-based PPL in Junior High School 9 of Jember, all of them show improved teaching skills significantly.

Abstract

The quality of food that is good in bacteriological, chemical and physical must always be maintained in order to avoid diseases or health problems. Healthy and safe food is an important factor to improve the standard of public health. Seblak is a ready-to-eat Indonesian food which until now has never been carried out research about what kinds of bacteria in it. Seblak is a food made from raw crackers which is then deliberately soaked using hot water to have a chewy texture. This study aims to determine what types of bacteria are contained in seblak, through the process of isolation and identification in the macroscopic, microscopic and biochemical way. This study used 5 samples, which was repeated 5 times for each sample. Bacteria were isolated from the sample using spread plate techniques and observed by growing colonies on the plate. Each different colonies was observed microscopically through gram staining and endospore staining. To strengthen the data, biochemical tests were also carried out, biochemical tests that have been done in this study were the oxidase test, catalase test, and indole test. The results of the study showed that the bacteria that were found from the samples are in the genus of Bacillus sp. because they show the morphological characteristics of the colonies that form concentric circles, meanwhile, microscopic observations show morphological characteristics of cells in the form of gram-negative bacilli and have the endospores.
