Abstract

High diversity of plant in University of Jember caused a safe, healthy, and beautiful environment. Almost all the plant are Spermatophyta and have woody form. Spermatophyta is a group of plant that has seed as the main characteristic. The woody plant (arbo) is a plant that has stem from wood, big form, and various type. This research aimed to know the kinds of Spermatophyta around Jember University. This research was included as a qualitative descriptive research, which is carried to drawing, interpretating and describing data systematically, factual, and accurate about the facts and the characteristics of Spermatophyta around of University of Jember. The research design contained location the selection of research location, sample and picture taking, and plant identifying. The method of sample taking was cruise. There were 4.644 of Spermatophyta that already found, that contained 80 species and grouped on 32 families.

Abstract

Leaves are an important organ for plants. One part of leaf is stomata which function as a place for gas exchange. The method used in this research is the observation of the morphology and anatomy of frangipani leaves (Plumeria acuminata) which are exposed to pollution and not exposed to pollution. The purpose of this study was to determine environmental conditions or as a bioindicator by observing damage to plants. Macroscopic damage to plants in leaf morphology and microscopic damage to changes in leaf stomata conditions. Observations show that the morphology of frangipani leaves (Plumeria acuminata) which are not exposed to pollution is larger than frangipani leaves (Plumeria acuminata) which are exposed to pollution. The number of stomata in the abaxial part is more than the adaxial part. Meanwhile, the number of stomata on frangipani leaves (Plumeria acuminata) that were not exposed to pollution was more than those exposed to pollution. The stomata type on frangipani leaves (Plumeria acuminata) is anomocytic type with kidney-shaped covering cells.

Abstract

Cocoa parasite leaves (Dendrophthoe pentandra (L.) Miq) belong to parasitic plants against hosts which are potentially used as traditional medicinal ingredients. However, the efficacy of cocoa parasite leaves is still not widely known by the public. One of the properties from cacao parasitic leaves is able to treat mild diseases such as smallpox, hookworm, flu, cough and diarrhea as well as being able to be used as a treatment for serious diseases such as tumors and cancer. The bacteria causing infection generally come from gram negative bacteria, namely Shigella dysenteriae and Salmonella typhi which refer to enteropathogenic bacteria causing infection to the host. The existing controls still use antibiotic drugs that are used less procedurally and causing bacteria more resistant. Cocoa parasite leaf extract contains active compounds in the form of alkaloids and saponins which play a role in inhibiting bacterial growth. This study aims to determine the effective concentration on the effect of cocoa parasite leaf extract to the growth of Shigella dysenteriae and Salmonella typhi bacteria. The research method was by using diffusion so that by using wells with 5 repetitions. The concentration used was 8%, 10%, 12%, 14%, 16%. Data were analyzed by using ANOVA analysis to determine the effective concentration on the effect of extracts to the inhibition of bacterial growth. The significant values were indicated at 0,000 against Shigella dysenteriae and 0.042 bacteria against Salmonella typhi (<0,05). The data revealed that cocoa parasite leaf extract has the potential to inhibit the growth of Shigella dysenteriae and Salmonella typhi bacteria.

Abstract

Kombucha is a fermented drink from nata kombucha starter which is symbiosis between Acetobacter sp. And Saccharomyces sp. Which were grown in medium of A. bilimbi. A. bilimbi kombucha produces various types of acids, enzymes, alcohol and vitamins in addition A. bilimbi fruit contain flavonoids, alkaloids, triterpene saponins, terpenoids, and essential oil. This study aimed to analyze the influence of A. bilimbi kombucha on growth of E. coli. This kombucha has an antibacterial activity on E. coli growth. E. coli is a diarrhea causing bacterium. Concentration of kombucha used were 25%; 27.5%; 30%; 32.5%, and 35%. Antibacterial test using a pour plate method. Analysize tested using one way ANOVA and followed by post hoc test LSD with 95% levelof confidence. This research showed that Averrhoa blimbi kombucha perform antibacterial activity against E. coli and at concentration of 35% kombucha buluh perform inhibition which different significally (p>0.05). Keywords: A. bilimbi, A. bilimbi kombucha, E. coli.

Abstract

The high diversity of plant species makes the Kapas Biru Waterfall a suitable area of tourism, research and other related activities. The plant species in this area are mostly seed plants and shrub. The shrub is a tree-like plant but with shorter and smaller main stem. The woody stems alsobranching near the surface of the soil. The aim of this research was to find out the species of shrub plants in the area of Kapas Biru Waterfall. This descriptive explorative research was conducted to systematically, factually and accurately describe and interpret the data of shrub seed plants in the area of Kapas Biru Waterfall. The study was conducted from April to May 2017. The research design included the selection of research sites, sampling and drawing, and plant identification stages.Samples were collected using total explore sampling method. Research result showed that there are 562 shrub plants in Kapas Biru Waterfall. They consist of 19 species incorporated in 11 families. Those family are Asparagaceae, Rutaceae, Asteraceae, Euphorbiaceae, Oleaceae, Arecaceae, Verbenaceae, Rubiaceae, Melastomataceae, Solanaceae, and Araliaceae.

Abstract

Indonesia has a wide variety of of moss plants. Approximately 1500-2000 types of true moss and liverworts are found in Indoensian territory. Moss are commonly found in humid habitats, in climatic conditions of tropical forests and waterfalls such as Kapas Biru Waterfall Pronojiwo Lumajang. This descriptive explorative study aimed to identify moss species found in Kapas Biru Waterfall Pronojiwo Lumajang. The sampling area was divided into 3 regions based on topography ie parking area, along the footpath heading towards the waterfall, and the area around the waterfall. The study was conducted using cruise method and plotting method. Several environmental factors such as temperature, air and soil humidity, soil pH, light intensity, wind velocity and elevation. The result showed that there are 13 species of mosses found belonging to 11 different families. Keywords: Biodiversity, Bryophyta, Kapas Biru Waterfall.

Abstract

Flipbook is organization of learning materials containing text, sound, animation, and video. This research aimed to produce a learning materials in the form of flipbook, especially on subject of animal’s growth and development for science class grade XII. The flipbook produced should be valid, effective and practical for use in learning process. Flipbook is a 2 dimensional application that is reliable and lightweight. This study used 3 stages from 4 dimensional model which are define, design and develop. The implementation of the developed product was planned by 2 different tests, the first was limited testing and second was field trial. All tests implemented in 44 students of 12 IPA SMA Budi Utomo Sidoarjo.

Abstract

Verbal discussion and arguments required as a necessity in academic activities. Argument is an important component in critical thinking, each individual in a professional and non professional activities require arguments. Argument also has an important role in the development of science. This argumentation skills can be improved by increasing the understanding of reading as a source of learning. This study aimed to stimulate student argument skills in the subject of Teaching and Learning Strategies using learning model of reciprocal teaching. Argument skills targeted adopted Toulmin’s Model of Argument. Result showed that there were increasing quality of student’s arguments in all six parameters with parameter of data, claim and warrants showing higher enhancement relative to the other three parameters namely qualifiers, rebuttal and backup.
